According to the characteristics of the stamping process to be carried out, the production and manufacture of large quantities of dimensions, geometric specifications of stamping parts (to protect the thickness, is not to pull, the appearance design of the test products) and precision provisions.

1. Large, small and medium-sized parts of the production of bending parts polyester, choose open mechanical equipment Longmen punch manufacturers.

2. In the production and manufacture of small and medium-sized stamping parts, we choose the mechanical equipment punch in the form of closed test structure.

3. Four-column hydraulic press is used for small and mass production, large and medium thick steel plate stamping parts.

4. In the mass production or the beginning of many production and manufacturing of complex parts, the use of high-speed punch or multi-process automatic punch.

The specification and model are defined according to the specification and punching pressure of pressing molds of stamping enterprise management department

1. The selected pound level of the high-speed stamping machine must exceed the total punching pressure required for stamping.

2. The travel arrangement of the punch should be moderate: the key height of the travel arrangement immediately endangers the mold shell is too large, and the die seat is separated from the reaming drill, and the reaming drill die or die guide pillar is separated.

3. The closing height of the punch should be consistent with the closing height of the stamping die, that is, the closing height of the stamping die is close to the middle of the larger closing height and the minimum closing height of the punch.

4. The specifications of the cabinet table in the work of the punch machine must exceed the size of the mold base under the mold shell, and leave space for installation and fixing, but the operating table should not be large, in case the operating table is not very good.

Depending on the material of the product

1, the material of the product must be metal material to be able to carry out high-speed punch.

2, the thickness and total width of the product, generally more than 5 mm high is not suitable for high speed stamping, and the total width of the stamping product is controlled by high speed molds.

3, by the high-speed punch of the product, must be if the pipe material and cutting, otherwise can not carry out high speed stamping.

According to the total number of stamping products and the rate must be clear:

Manufacturers have been applying low speed pull-down punch, not in line with today's low speed, if you want to press speed in more than 150 times, you can choose to replace the high-speed punch.

According to the precision of the stamping products:

High speed punch has C type and dragon type punch, dragon punch because of its unique production process, its manufacturing accuracy, reliability, speed level must be better than C type punch, therefore, if the customer has a particularly high requirement for stamping products, and the cost budget is sufficient, we must choose dragon type punch.
