Embodiment Construction

[0018] see Figure 1-3 A combined die-cutting die, which includes a laser die 2 and an etching die 3. The laser knife template 2 includes a wooden board (laser knife template) 21 and a blade 22 embedded in the gap on the surface of the laser knife template.

[0019] see Figure 4-6 , The etching knife template 3 includes an etching knife template 31 and a blade edge 32 formed on the surface of the etching knife template. The knife edge 32 has two circular blanking through-hole knives 33 , three straight-line knives 34 , and an arc-shaped connection between two adjacent straight-line knives 34 . The arc-shaped connection part is a circular arc with a radius of 1mm. The radius of circular blanking through-hole knife 33 is 2mm.

[0020] The etching knife template 31 is detachably embedded in the plank (laser knife template) 21. On the back side of the embedded plank (laser knife template) 21, there is a waste discharge card slot 23 communicating with the blanking circular ho...

Abstract

The invention provides a combined die cutting die which is capable of reducing burr and improving die cutting size precision during die cutting. The combined die cutting die comprises a laser cutting die and an etching cutting die, wherein the laser cutting die comprises a laser cutting die plate and a cutter blade embedded in a seam of the surface of the laser cutting die plate, the etching cutting die comprises an etching cutting die plate and a cutter point formed on the surface of the etching cutting die plate, the etching cutting die plate is detachably connected onto the laser cutting die plate, and the cutter blade and the cutter point form a cutter of the combined die cutting die.

Description

technical field [0001] The technology relates to a die-cutting die, specifically, a combined die-cutting die formed by combining a laser die and an etching die. Background technique [0002] In the entire die-cutting process design, the design of the die is particularly important. The designer should design the corresponding cutting die according to the precision, material, shape and structure of the product. The cutting die designed by the designer should be suitable for die-cutting processing as much as possible, simple and reasonable, with high material utilization rate and less difficulty in waste discharge. Especially for products with small holes, the process of die-cutting and waste discharge is very important. If it is not mastered well, it is very likely that the product will not be produced or cause waste. The purpose of developing a refined knife mold is to give full play to the benefits of the equipment, but also to take into account the service life and cost o...
