Select 'Hardware' for the processing skills of each precision stamping shrapnel

Now, the processing equipment and production line of mechanical precision stamping shrapnel are developing towards the depth and breadth of numerical control (NC) and computer control (CNC). However, with the changes in the information and geometry of precision stamping shrapnel, processing skills have also been developed. 1. The shrapnel of variable precision stamping parts has completed the moldless plastic processing of the shrapnel outer diameter, variable pitch and variable steel wire diameter (three-variable) suspension precision stamping parts. Since the development of three-change precision stamping shrapnel, tapered steel bars have been used for winding processing on CNC lathes, but the yield and quotation are not ambitions. Now it is changed to go through the spring coiling machine under the heating state to control the roll speed and drawing force to obtain the required cone shape, and use the processing waste heat for quenching. 2. The shrapnel rod of the hollow and stable precision stamping parts is made of low-carbon boron steel plate rolled and welded. 3. The torsion bar is made of high-purity 45 steel. After high-frequency quenching, it obtains the appearance of high hardness and large residual contraction stress, and then improves the fatigue life and anti-loosening ability. 4. The shrapnel of precision stamping parts widely used in electronic products is basically formed by stamping and active bending processing. Now the first thing is to develop the joining skills of composite materials.
