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

2, the thickness and total width of the goods, generally more than 5 mm high is not suitable for high speed stamping, and the total width of the stamping goods by high speed molded shell.

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

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

1. Large, medium and small parts of the cutting parts of the bending parts of the polyester can be tilting punch manufacturers production and manufacturing, the selection of open mechanical equipment punch.

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.

5. Clarifying specifications and models, according to the specifications and punching pressure of pressing molds of stamping enterprise management department

1. The selected pound level of the punch must exceed the total punching pressure required by the stamping.

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

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 of the punch and the minimum closing height.

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.
