Nowadays, in the production of stamping parts for cars, most of them are produced by cold stamping, and in the time of making stampings, the material of the stamping must be debugged before it can be used in production. After many years of research, engineers have put forward severe requirements for the commissioning of cold dies, so that after these detailed adjustments, these cold dies can exert more energy in the process of making stamping parts.
However, the cold die has to go through some step-by-step process before producing the stamping parts of the car. Generally, in the commissioning, the first step must be to determine whether these cold stamping dies can be applied to the press. In short, the newly produced cold dies can be smoothly installed on the press. Assuming that it can be mounted on a press machine, it means that the cold die has no problem in the general structure and can be used for the next step of debugging.
After determining that the cold die can be applied to the press, the next requirement is to determine whether the specified blank can be machined into the specified stamped part by the cold die. Generally, in this step of debugging, it is required to use these blanks for the processing of stamping parts, because in the commissioning, the basis for judging that the blanks are matched with the cold stamping die can be confessed without a single commissioning. In the commissioning of this step, after passing through the operation process of a certain number of stamping parts, the effect of the quantitative data calculation can be used to determine that the blank and the cold die are in full compliance.
Now that we have completed the first two operations, we will need to check whether these cold stamping dies are made in the stamping parts of the car. Generally, in the process of checking whether these stamping parts meet the requirements, we do not only need to compare the planned drawings of the stamping parts with the manufactured products, because the assembly of the car is a messy process, in the assembly process, assuming any stamping The production of the piece does not meet the standard pile, it may lead to the car can not be produced and put into operation after all. When checking whether the stamped parts produced meet the requirements, it is assumed that these processed stamping parts do not meet the requirements, and the reasons should be sought from the processing technology and the cold stamping die. After all, this type of stamping parts can be planned with the drawings. It is common to ensure that cars can travel safely.
After determining that the stampings made by the cold stamping meet the requirements of the drawings, we also need to check the standard and size of these stampings in the next commissioning. Assuming that the requirements are not met, the standard and size of these cold dies can be adjusted until the requirements are met.
Some people will see that the debugging work of the cold die has not ended yet. In fact, the actual commissioning operation is not over. In the final debugging work, it is judged that the stamped parts of the processed car are in full compliance. After the request, a severe operation procedure is also determined for this cold-rush simulation, so that the cold die can be used by more people in practice.
In fact, in the whole process of commissioning the cold stamping die to make the stamping parts of the car, the commissioning personnel must pay attention to the time when the debugging hypothesis finds that the cold die is stable and the batch production is affected. The commissioning personnel should adjust the cold die in time, after all, it is the cold die. Can complete the purpose of safe production.
