Do you stamp metal springs with dies?
- Metal spring stamping die, because the metal stamping parts with tight size and shape will not damage the appearance quality of metal spring stamping parts and the service life of the mold as usual, so the quality of stamping parts is stable and the interchangeability is good.
- As usual, metal spring stamping has no natural debris, less material loss, and no other heating and shaping equipment. It is a material-saving, energy-saving processing, and low-cost stamping parts.
- The processing scale of metal spring stamping parts is large, and the parts with huge shapes, such as small clock stopwatches, to automobile longitudinal beams and covering parts, coupled with the cold deformation and hardening of stamping materials, have great strength and rigidity during stamping .
- The production efficiency of metal spring stamping is high, the operation is convenient, and it is easy to realize mechanization and automation. This is because stamping dies and stamping equipment depend on the penalty of disposal. Usually, the number of strokes per minute can reach dozens, and the high pressure can reach hundreds or even thousands of strokes per minute. Each punch stroke can get approximately one punch.
The main function of hardware spring
Hardware spring is a widely used elastic part, which has the characteristics of easy deformation and high elasticity. Let me briefly talk about the main functions of hardware springs:
- Smooth shock and shock absorption Use metal spring deformation to absorb the energy of shock and vibration, such as buffer hardware springs on vehicles and forging equipment, vibration-absorbing hardware springs in couplings, etc.
- Control the movement of the organization Use the elastic force of the hardware spring to maintain the contact between the parts to control the movement of the organization, such as the valve hardware spring in the internal combustion engine, the control hardware spring in the brake, clutch, cam organization, governor, and safety valve On the security hardware springs and so on.
- Storage and output energy Use the energy stored when the metal spring deforms to do work, such as the hardware spring of the wall clock, the hardware spring of the gun bolt, and the hardware spring in the automatic return device of the tool holder in the automatic machine tool, etc.
- Measuring the size of the force The size of the load is measured by using the characteristic that the deformation of the hardware spring is linearly related to the load it bears, such as force measuring devices, hardware spring scales, and metal springs in engine dynamometers.
What material is used for stamping spring leaf
Spring sheets are generally used as sensitive components, elastic supports, positioning devices, flexible connections, etc. in testing instruments or automatic devices. The use of spring sheets of different materials is also different.
The spring piece can be made of stainless steel. The spring piece can produce large elastic deformation when loaded, and convert mechanical work or kinetic energy into deformation energy. After unloading, the deformation of the spring disappears and returns to the original shape, and the deformation energy is converted into mechanical work or kinetic energy. . Spring leaf has high elastic limit, fatigue limit, impact toughness and good heat and corrosion resistance.
After heat treatment and cold drawing hardening, the 65mn spring sheet will have high strength and certain toughness and plasticity. Can be used in wear-resistant mechanical parts.
70# steel has the advantages of cheap price and convenient source of raw materials. The disadvantage is that the elastic limit is low, it is easy to lose elasticity after repeated deformation, and it cannot work normally at 130 degrees. Due to the advantage of convenient price, customers often come to use it as the raw material of spring leaf.
Bronze spring piece, bronze has the characteristics of low melting point, high hardness, strong plasticity, wear resistance, corrosion resistance, bright color and so on. It has excellent resilience performance, can be compressed up to 70% of its height, and can withstand 100,000 times without deformation; high compressive performance, can be repeatedly compressed in two directions; durable fatigue resistance; easy to electroplate and weld; excellent electrical conductivity; ultra-low magnetic Conductivity. Bronze spring sheets are often used as shielding electronic materials.
When selecting materials for spring sheets, the use, importance, load nature, size, cycle characteristics, working temperature, surrounding medium and other conditions of use of the spring sheet, as well as factors such as processing, heat treatment and economy, must be considered to select the material. , which can achieve twice the result with half the effort.
