In addition to reasonable mold structure, high precision, good heat treatment effect and correct selection of punch and punch mounting accuracy, the correct use, maintenance and maintenance of the mold can not be ignored.

 

(1) Before installing and using the mold, it is necessary to strictly check the dust and check whether the guide sleeve and the mold are lubricated.

 

(2) Regularly check the press and die holder to ensure the coaxiality accuracy of the upper and lower turntables.

 

(3) Install the mold on the turntable to ensure that the mold direction is consistent with the mold, especially the mold (non-circular, square) should be more carefully designed in the expected direction.

 

(4) After installing the mold, check if the fixing screws are locked.

 

(5) The edging of the press, the grinding of the press and the grinding of the press rapidly expand the wear of the press, accelerate the wear of the press, reduce the quality of the press, and shorten the service life of the press.

 

(6) Spare parts should be used to ensure the rotation and production requirements of the molds commonly used in large-scale production.

 

(7) Stamping personnel should use soft metals (such as copper, aluminum, etc.) to make operating tools to prevent damage to the mold during installation.

 

(8) During the transportation process, the mold should be handled carefully, and the garbage should be thrown at will, so as not to damage the edge and direction of the mold.

 

(9) After using the mold, return to the specified position in time to prevent rust.

 

(10) In order to ensure the service life of the mold, the mold spring is replaced regularly to prevent spring fatigue damage and affect the use of the mold.

 

Common problems in the use of stamping dies.

 

In order to meet the production needs, molds or special molds are usually required, such as bridge molds, blind molds, main molds, hole molds, stamping molds, die and combination molds. Special or molded molds can greatly increase productivity, but molds are more

expensive. The cost of the mold is usually 4-5 times higher than the cost of a conventional mold. To avoid mistakes, we should pay attention to the following principles:

 

(1) Check the mounting direction of the mold to ensure that the mounting direction of the mold is the same.

 

(2) Adjust the stamping depth of the mold as needed, no more than once.
