Wire Thread Inserts of the installation process

1, drilling
Thread specification
The threaded holes in the table with the corrupted into Φ standard bit pruned.Be careful not to drill into conical or not vertical, bored after chamfering, chamfering depth should not be more than 0.4 P (pitch).Because of too much chamfer for screwing in a screw and can lead to poor assembly.
2, tapping
With the corresponding specifications of the special tap, a screw in the drilled hole tapping, tapping must exceed the length of the length of a screw.All tapping hole.Tapping screw holes within the field of precision decide the standard tolerance zone, the user to properly select tapping method, and lubrication;Blind hole tapping into the appropriate, in case of broken tap.After tapping screw thread hole should be clean, prevent the screw hole and silk suites have sundry, general use compressed air blow gun.Tapping after application of the corresponding holes is in accordance with the provisions of the thread plug gauge to check accuracy requirement.Especially new tap and tap is close to wear must be used when using thread plug gauge to check to identify tap screw holes is available.

3, installation,
Use special tool to put a screw in the installation tools, installed to handle embedded guide slot rotation tool handles, by its diameter was reduced by twisted shank installation along the screw hole thread screwing in the screw hole, and make it within 0.25-0.75 times surface with empty thread.Small when installing a screw and 14 * 2 or more coarse thread silk set of "T" type slot can be used when installation or simple screw head with installation, and pay attention to don't impose on a screw to install the handle large axial force to prevent jump "teeth".Steel wire spiral sets is to use a special tool stuck its installation handle, for quick installation or assembly line assembly, a screw using electric or pneumatic semi-automatic installer to obtain a fast and reliable installation.After installation, a screw for testing standard which is formed by the internal thread pit accuracy, can examine corresponding level gauges.
4, install handle broken
Hole, a screw to install the handle must be broken, thrust generally use the cross on the horizontal line, install the handle, with around 200 g bang head on it can be removed.Install the handle will be from the break tank break.Broken handle installation should begin from the screw hole will be removed.
Take a screw: problems during the installation process or due to the use of time is too long a screw, a screw can be removed should use cone with edge detection and set of tools, to prepare the handle, with a bang head on, with the hand strength to press the handle counterclockwise rotation can take out a screw.

The meaning of the spring

Spring is a kind of mechanical parts use flexibility to work.Usually made from spring steel.Used to control the movement of the parts, moderate impact or vibration, energy savings, the size of the measuring force, etc., widely used in machinery, instrument.The sort of spring is complex, the shape can be divided into the disc spring, circular spring, leaf spring, coil spring, truncated cone vortex coil spring and torsion bar spring, etc.According to the mechanical properties are divided into compression spring, torsion spring, profiled spring, etc.According to the production process can be divided into cold coil spring and hot coil spring.Ordinary cylindrical spring because of its simple manufacture, and can be made into various types according to the load situation, simple structure, is the most widely used.Spring manufacturing materials in general should have high elastic limit, fatigue limit, impact toughness and good heat treatment performance, such as the commonly used carbon spring steel, alloy spring steel, stainless spring steel and copper alloy, nickel alloy and rubber, etc.Spring manufacturing methods of cold rolled and hot rolled method.Spring wire diameter less than 8 mm with cold roll method, generally greater than 8 mm with hot volume method.Some spring after made to crush or shot peening treatment, can improve the bearing capacity of the spring.

Spring compression function

Observe all kinds of electric switch, switch the two contact, there must be a head filled with spring, in order to make sure the two s close contact, conduction is good. If poor contact, the contact point of resistance, a current flows through the heat generated by the larger, serious when will be in contact with the metal melt. Two metal column bayonet base have been equipped with spring to contact good;As to the center of the screw base metal as well as all the plug-in socket metal reed, its function is to make both sides close contact, in order to keep to the same good. In the cassette tape, one piece of phosphor bronze reed, use it when the elastic bending deformation to make head closely contact with the tape. In the stapler is a long spiral spring its role on the one hand is top tight staple, on the other hand, when the front of the pin after being launched, can be nailed to the front for comfortable behind the launch, in this way, can automatically to nail a all push to the front, until all the nails out. Many machine automatic feeding, automatic automatic bullet taste of  this function by the spring. In addition, like clothes clip, ball-point pen, pen clip on spend spring compression function on clothes.

Inherit the torsional deformation of the custom spring

 Custom springs  steel wire around the spiral spring.Helical spring type is more, according to the shape can be divided into ordinary cylindrical helical spring and variable diameter coil spring;By direction can be divided into the lefthand helix spring and dextral spring.Cylindrical helical spring has simple structure, easy fabrication, the most widely used, its characteristic line is straight line, as a compression spring, tension spring and torsion spring.When the load is big and restrictions on the size and the radial, two different diameter of compression spring can be set in spring become combination.Variable diameter coil spring cone spiral spring, volute spring and concave in helical spring, etc.The cushioning property of conical helical spring is good, can bear larger load.Volute spring can store more energy and under high load, but the manufacturing process is more complicated.Concave in the performance of the helical spring with conical helical spring, more used to cushion and mattress, etc.Spring steel wire surface load of the circular and rectangular, circular cross section in the most commonly used.

Helical spring torsion spring, is under torsional deformation of spring, its working part is tightly wound into a helix.Torsion spring end structure is processed into various shapes of twisting arms, rather than GouHuan.Torsion spring is often used in the mechanical balance institutions, in automobile, machine tools, electrical appliances are widely used in industrial production.

Several methods to improve the service life of the spring

1) thermomechanical treatment
Thermomechanical treatment is the deformation of steel strengthening and heat treatment strengthening both together, further improve the strength and toughness of steel.Thermomechanical treatment are high, moderate in low temperatures.High temperature thermomechanical treatment is produced under the stable state of austenite deformation immediately after quenching, can also be combined with forging or hot rolled, namely thermoforming immediately after quenching.60 si2mn steel manufacturing automobile plate spring, after the high temperature thermomechanical treatment (930 ℃ + 18% hot variables, oil quenching), with 650 ℃ high temperature tempering of x 3.25 min, its strength and fatigue life have been greatly improved.
(2) spring isothermal quenching
Can be used for small diameter or hardenability enough spring isothermal quenching, which can not only reduce, but also can improve the tenacity.Best again after isothermal quenching tempering, can improve the elastic limit, tempering temperature and isothermal quenching temperature are the same.
(3) the shot blast
Shot peening treatment is currently the most widely used one method to improve the surface quality of the spring.Spring requires a higher surface quality and surface defects such as scratches, folding, oxidation decarburization tend to become spring job stress concentration and fatigue fracture source.If use small high-speed spray the surface of the spring, steel shot peening treatment, not only improve the surface quality of the spring, to improve the surface strength, make the surface in the compressive stress state, so as to improve the spring fatigue strength and life use.

Wire installation problems that should pay attention to during the process of a screw

  



(1) before installation, clean them repeatedly set screw hole, silk, remove the impurities in the thread;
(2) the installation time, using special installation tools, nor axial force, avoid the phenomenon of disorderly buckle;
(3) if the screw hole is blind holes, should remove the broken handle installation, to avoid more tailings;
(4) for the installation after take out the wire sets under any circumstances can no longer use;
(5) after the demolition of silk set, its substrate screw hole should be clean, check the screw hole meet the standard requirement, and can replace the wire sets.

We Are Familiar With What Kind Of Machine-------It Springs

Speaking of spring, surely many of us think of a child playing the kind of trampoline inside will think of spring steel used ink tube where there are springs that basketball it? This maybe a lot of people do not understand. Since there are so many springs, spring machines that do are the same? We work together to explore!

Spring machine according to the degree of automation is concerned, can be divided into CNC helical coil machine and mechanical spring machines; by function points, can be divided into compression spring, torsion spring machines, tension spring machine, spring grinding machine, multi-function computer spring machine; Press structure to points, can be divided into traditional and non-cam engine cam spring machine; cam and cam unit can also be subdivided without changing lanes without changing lanes spring machine and spring machine. According to the driving mode is divided into: semi-automatic, automatic, computer-controlled CNC type and style. Different types for different purposes, like everyone is more versatile, or automatic type, because this way we operate is not so complicated. Technologically advanced society, many of which are automated, intelligent, this pattern slowly become a part of life everyone, also gradually expand the market.

Ever uttered such a joke, when the first contact with the computer spring machine, that machine is a computer inside the spring, also doubts, the computer inside a spring or spring it? Later learned that after the adoption and professional people to understand is actually a machine come forward. This also reflects a problem that many varieties of spring machine, use is also more widely, consumers need may vary depending on the performance they need to choose.

How To Determine The Level Of Computer Spring Machine Precision Standards

XinXiang ChangLing Metal Products Co.,Ltd

For the uninitiated, the purchase of computer spring when unable to determine the accuracy of the level of the standard, the accuracy level is very important to use, so we have to learn how to determine the level of accuracy of computer spring.

Computer spring machine detects displacement in accordance with strict standards for testing, you can ensure that the spring force in different parts of the test pressure plate are the same, you can ensure that, within the scope of the test force to meet, the load will not cause any load sensors displacement sink.In addition, the impact of computer spring machine loading method of the test results also exist. The first loading method is the use of an AC motor drive transmission system to load, the loading speed can not be adjusted. For the spring element, the stress is present. Fast compression automatically when the data collected and slow compression or high compression data collected varies greatly. With variable speed systems such as AC servo control system, by simulating the spring working condition, measuring spring in the state of internal stress.

With the development of computer technology, SCM function is relatively simple, the disadvantage would be to improve the computer, intelligence expert system feature set, parameter selection, mouse operation, intelligence level has been greatly improved. Just gently motor mouse, you can control. This can reduce the amount of labor.

Spring manufacturers tell you in the spring of idea

1.Without supporting ring spring and spring wire diameter interloper spring should not be welding head, but end wire should not have obvious loose, deburring.Would all the welding head more strands of spring, the weld length should be less than three times the cable diameter (the longest not greater than 10 mm).Heating length should be less than a circle, should be polished smooth after welding, gas welding when the welding parts should be partial annealing at low temperature.

2 according to the product, bearing ring can use cold and hot and the two methods.Using thermal and spring are not allowed to be heated to spark or white, silicon manganese steel temperature is not higher than 850 ℃.With effective support circle should be effective contact, clearance shall not exceed 10% of the nominal gap between circle.

3, many strands of spring can be adjusted by the lead decision, winding line distance can make the necessary adjustments.Screw pitch desirable 3 ~ 14 times wire diameter, but generally take 8 ~ 13 times is preferred.The spring force and free height, and end ring, outside diameter and the steel wire performance is closely related, and can be adjusted through changing one or a few.

Teach you how to choose good quality steel wire spiral sets

Wire Thread Inserts is a kind of a screw inserts for non-ferrous metal thread protection and development, applicable to the threaded connection.Helicoil is widely used in aerospace industry, shipbuilding, defense industry, automobile industry and other industries.As steel wire spiral sets of the application of more and more widely, how to choose the suitable wire screw becomes especially important.
Steel wire selection is a screw should consider the following factors:
1, the shear strength value of the parent metal at the same level between the two values, should choose low.
Listed in the table 2, the shear strength of the numerical value of room temperature and under high temperature, the value is much smaller, when choose, should make the necessary calculations.
3, to ensure that the selected thread specification fully comply with the design standards.
4, screw the practical tensile strength, especially in the lower strength level, much bigger than the calibration of the ratings.To this point in the wire should be fully considered when the selection of a screw.

What functions can spring applications

Delisert Spring

Spring in the widely used long ago.It is an accumulator, it has the role of storing energy.Ancient bow and crossbow is two kinds of spring in the broadest sense of the term.
Now tell me about the function of the spring:
1 buffer function
Between the frame and the wheel is equipped with spring, the use of the elasticity of the spring to slow down the vehicle.So each motor vehicle spring use above is pretty big.
2, vibrating voice function
When the air from the harmonica and accordion in the spring flow hole, the impact of reeds, reed beautiful sound.
3, measurement function
How to make spring balance?It is within the elastic limit, elongation of the springs (or contracts) with external force is proportional to the.Use this property to spring balance is made of.
4 and reset function
Custom Spring deformation under the action of external force, external force is removed, the spring will return to normal state.A lot of equipment and tools is to use this property to copy.For example, many buildings is installed on the door hinge reset spring, after people in and out of the door will automatically comfort.People also use this function from the automatic pencil, the article such as automatic umbrella, is very convenient.
Spring has other functions, has been widely applied, jiangsu king smart spring with the first-class products, first-class service welcome new and old customers call advisory business negotiations.

Spring in the practical application in life

What are the practical application in the spring in your life?The king of the king smart spring manager made some simple elaboration:
1, control the movement of the machine, such as the engine valve spring, control of clutch spring, etc.
2, absorption of vibration and impact energy, such as buffer spring under the car, train carriages, coupling of the vibration-absorbing springs, etc.
3, storage and output energy as power, such as clock spring, spring in the gun etc.
4, used as the load components, such as force-measuring device, the spring spring balance, etc.The ratio of the load and deformation of the spring called spring stiffness, the stiffness, the greater the spring harder.
According to stress nature, spring can be divided into tensile spring, compression spring, torsion spring and bending spring, according to the shape can be divided into the disc spring, circular spring, leaf spring, coil spring, truncated cone vortex coil spring and torsion bar spring, etc.Ordinary cylindrical spring because of its simple manufacture, and can be made into various types according to the load situation, simple structure, is the most widely used.Jiangsu king smart spring with the first-class products, first-class service to welcome new and old customers call advisory business negotiations.
