Anti-sticking material device with hole-punching and hole-flanging functions

Abstract

The invention discloses an anti-sticking material device with a hole-punching and a hole-flanging functions, comprising a punch head, a female die and a hole-flanging inner separation block. The anti-sticking material device is characterized in that the punch head comprises a cutter bar and a cutter head connected with the cutter bar, wherein the cutter head comprises a front cutter head used for punching a hole and a main body part used for flanging the hole, and the cylinder diameter of the main body part is more than that of a front cylinder; the female die comprises a hole-flanging female die and a hole-punching female die, wherein a through hole is arranged in the hole-flanging female die, the hole-flanging inner separation block is arranged in the through hole, the hole-punching female die is arranged on the hole-flanging inner separation block, and a blanking through hole is arranged in the hole-punching female die. When the punching and the flanging are carried out in the prior art, a punched bottom hole does not have the female die; in the production process, the small hole-punching waste materials are adhered to the hole-flanged opening and are difficultly removed; because the inner separation block is arranged in the hole-flanging female die and the hole-punching female die is increased on the inner separation block, the problem of the waste materials during hole flanging is solved; and the invention has simple structure and is easily applied to production operation.

Description

technical field [0001] The invention relates to the field of stamping dies, in particular to a punching and hole turning anti-sticking material device. Background technique [0002] In factory production, when punching and reversing the processed materials, the die is generally not used for punching small bottom holes. During the operation, sometimes small punching waste will stick to the reversing hole. In the case of parts, it cannot be removed, so there is a need for a mold device that can solve the problem of waste. Contents of the invention [0003] In order to achieve the above technical purpose, the present invention provides a punching and turning hole anti-adhesive material device, including a punch, a die, turning holes and removing blocks, characterized in that: [0004] The punch includes a cutter bar and a cutter head connected with the cutter bar, the cutter head includes a front cutter head for punching and a main part for turning holes, and the diameter of...
