Continuous punching die

Abstract

The invention discloses a continuous punching die. The continuous punching die comprises a die handle, an upper die plate, guide sleeves, a convex die body, a lower die plate, guide pillars and a concave die body, wherein the die handle is vertically arranged over the upper die plate; the guide sleeves are arranged on two sides of the upper die plate; and the convex die body is installed under the upper die plate. The continuous punching die further comprises a fixing plate, guide devices with springs, a first punch head, a second punch head and a base plate, wherein the upper portion of the fixing plate is connected with the upper die plate, and the lower portion of the fixing plate is connected with the first punch head and the second punch head; the upper portions of the guide devices with the springs are connected with the fixing plate, and the lower portions of the guide devices with the springs are connected with the base plate; the guide pillars are arranged on two sides of the lower die plate; the upper die plate and the lower die plate are connected together through sleeving connection of the guide sleeves and the guide pillars; the concave die body is installed on the lower die plate and under the convex die body, and the concave die body comprises a limiting plate which is connected with the concave die body through a spring. The continuous punching die can punch multiple holes, achieve rapid forming, guarantee accurate positions of punched holes, and conduct continuous punching, the efficiency is high, the service life of the punch heads can be prolonged, and the cost is lowered.

Description

technical field [0001] The invention relates to the technical field of dies, in particular to a continuous punching die. Background technique [0002] In machining production, it is often necessary to open holes or grooves on metal materials. If drilling or milling is used, the workload is large, the work efficiency is low, and it is not safe. The use of punching die processing can improve productivity, and the product quality is stable and safe, but there are some defects in the punching die in the prior art. The existing punching die has only one punching head, and only one punching head can be punched at a time. Holes, if continuous multiple holes are punched on the metal material, it is necessary to repeat the punching action again and again to complete the punching of multiple holes, and when the continuous hole is punched, the metal material is prone to deformation, punching The position of the hole is not accurate enough, resulting in a low forming rate of the hole, ...

[0002] In machining production, it is often necessary to open holes or grooves on metal materials. If drilling or milling is used, the workload is large, the work efficiency is low, and it is not safe.

The use of punching die processing can improve productivity, and the product quality is stable and safe, but there are some defects in the punching die in the prior art. The existing punching die has only one punching head, and only one punching head can be punched at a time. Holes, if continuous multiple holes are punched on the metal material, it is necessary to repeat the punching action again and again to complete the punching of multiple holes, and when the continuous hole is punched, the metal material is prone to deformation, punching The position of the hole is not accurate enough, resulting in a low forming rate of the hole, resulting in defective products, wasting materials, and increasing the cost
