Clamping and trepanning die for hardware

Abstract

The invention discloses a clamping and trepanning die for hardware. The clamping and trepanning die comprises a lower die body and an upper die body. The lower die body is located under the upper die body. The clamping and trepanning die further comprises horizontal transverse air cylinder sets, a horizontal longitudinal air cylinder set, vertical air cylinder sets and compression rings. A workpiece fixing table used for installing a workpiece is arranged in the middle of the lower die body. The horizontal transverse air cylinder sets and the horizontal longitudinal air cylinder set are fixedly installed on the periphery of the upper end face of the lower die body. Air cylinder telescopic rods of the horizontal transverse air cylinder sets and the horizontal longitudinal air cylinder set face the workpiece fixing table. The vertical air cylinder sets are installed on the lower end face of the upper die body. The lower sides of the vertical air cylinder sets are fixedly connected with the upper surfaces of the compression rings, and each of the lower end faces of the compression rings and the upper end face of the workpiece fixing table are coated with an ultra-hard wear-resistant coating. The clamping and trepanning die for the hardware is reasonable in structure, the machining and positioning precision of the workpiece is improved, the workpiece is prevented from deforming, the service life is long, and the labor intensity is greatly reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of hardware processing equipment, in particular to a hardware clamping and opening mold. 【Background technique】 [0002] At present, the processing of hardware holes requires multiple clamping, multi-process, and multi-station processing, resulting in problems such as poor processing accuracy and low efficiency. Deformation also brings unnecessary troubles to the subsequent assembly, such as the relevant dimensions are not in place during assembly, the appearance is poor, etc., which require the staff to repeatedly repair and adjust during work, but the repair effect is not very obvious, and Time-consuming and labor-intensive, high labor intensity also affects production efficiency and product qualification rate. In order to ensure the machining accuracy and positioning accuracy of hardware holes and improve production efficiency and product qualification rate, it is necessary to propose a hardware clampin...
