Look at the process plan of stamping die

The working principle of Dalian stamping die is to use the same shape punch and concave die to process various geometric solid products according to the design requirement by pressing the metal material through the pressing plate. Die pressing force, die clearance, etc. The punching die has simple single punching die and complex continuous die. The main consideration is machine tool pressure, die punching force, die unloading force. The stroke times of ordinary press can reach dozens of times per minute, and the high-speed pressure can reach hundreds or even thousands of times per minute.

And each stamping stroke may get a stamping piece. The supply status of metal materials for stamping is generally sheet and strip materials of various specifications. Sheet metal can be used in the production of Engineering die, strip material (coil) can be used in the production of continuous die, and can also be used in the production of Engineering die. If the workability of the parts is too poor, we should consult with the designer and put forward the plan of modifying the design.

If the production batch is too small, other production methods should be considered for processing. After major repairs or changes in the original design performance of the lifting machinery, static and dynamic load tests must be carried out before use, and the equipment power management department, security department and use department jointly identify and accept the qualified lifting machinery, and compare the quality, cost, productivity, grinding and maintenance of the mould, service life and operation safety of the mould.

Choose a good process plan from it. In addition to the shape and size of the parts, it is important to understand the requirements of the accuracy and surface roughness of the parts. The rationality of benchmark selection and dimension labeling of parts and the suitability of dimension, position and shape accuracy for stamping are analyzed. Arrange reasonable stamping sequence. Attention should be paid to ensure that the deformation area of each process is weak, and the formed part (including the punched hole or shape) should not be involved in the deformation in the subsequent process.
