Optimum assembly steps of stamping die

The best assembly steps of stamping die

The assembly of stamping die is a meticulous work. If there is no clear assembly idea, the stamping die will be disassembled and reassembled many times after assembly, which greatly reduces the production efficiency and the quality of stamping die. In order to save everyone time, Zhonghua Standard Parts summarizes the following five assembly steps of stamping die.

(1) Select the assembly datum. When assembling, the datum parts should be selected first. The principle of selecting benchmark parts is determined according to the dependence of the main parts of the mold during processing. The main parts that can be used as assembly reference parts are punch, die and die. Punch die, guide plate and fixed plate, etc.

(2) assembly of components. Component assembly refers to the assembly work of connecting more than two parts into a component according to the specified technical requirements before the final assembly of the mold. Such as the assembly of the die frame, the assembly of the punch and die with the fixed plate, and the assembly of the parts of the unloading and pushing mechanism. These components should be assembled according to the functions of each part, which will ensure the assembly accuracy of the whole Dongguan stamping die.

(3) overall assembly. Assembly is the process of combining parts and components into a complete Dongguan stamping die. Before the final assembly, the reference parts should be selected and the assembly sequence of the upper and lower dies should be arranged.

(4) Adjust the gap between the punch and the die. When assembling the die, the uniformity of the gap between the punch and the die must be strictly controlled and adjusted. Only after the clearance is adjusted can the screws and pins be tightened.

The methods for adjusting the gap between the punch and the die mainly include light transmission method, measurement method, gasket method, coating method and copper plating method.

(5) inspection and debugging. After the stamping die is assembled. It is necessary to ensure the assembly accuracy, meet the specified technical requirements, and check the functions of various parts of the mold according to the technical conditions of mold acceptance. Try the mold under the actual production conditions, and adjust and correct the mold according to the production conditions of the trial mold. When the trial mold is qualified, the mold processing and assembly will be basically completed. ;
