Description

Scrap cutter set

technical field

The utility model relates to the treatment of stamping waste materials, in particular to a cutting knife group which can cut the stamped waste materials into three sections to facilitate the discharge of the waste materials from the waste material channel.

Background technique

In the stamping process, there will be waste materials. When the waste materials are too large, they often need to be cut into several sections and then discharged in sections. The current scrap cutter has the same structure as the ordinary cutter, specifically, the front end is tapered, and the tapered front end is used to stamp the scrap board surface to complete the cutting. There is no problem with the cutter with this structure when the waste material only needs to be cut into two sections to be sent out, but when the waste material needs to be cut into three sections to be sent out smoothly, two or more knives need to cooperate to form a knife set. There will be disadvantages in the knife set formed by the combination of structural tools. Specifically, as shown in Figure 1, due to the cooperation of the tapered front ends of the two cutters, the distance between the cutters is larger at the top and smaller at the bottom, and the cut waste is slightly larger than the discharge gap between the cutters. Between the knives, it cannot be discharged smoothly.

Contents of the invention

The purpose of the utility model is to overcome the shortcomings of the traditional waste cutting knife set, and provide a waste cutting knife set that can satisfy the smooth discharge of middle-section waste.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a scrap cutting knife set, including a first knife body, a second knife body, and a knife holder. The first cutter body and the second cutter body are all vertically installed on the knife rest, and the bottom ends of the first cutter body and the second cutter body are connected with the cutter rest; the first cutter body is long block, and its left side is a vertical plane, and the upper It is a slope; the angle between the top and the left side is 125 degrees; the right side includes the first side connected to the top and the second side below the first side; the first side and the second side are vertical planes, and the first side and the second side The junction of the two sides is an arc-shaped transition; the upper side cooperates with the first side to form a knife edge; the second knife body is in the shape of a long block, the right side is vertically parallel, and the upper side is an inclined plane; the angle between the upper side and the right side is 125 degrees, and the left side includes and The first surface connected above and the second surface lower than the first surface; the first surface and the second surface are both vertical planes, and the connection between the first surface and the second surface forms an arc transition.

The distance between the adjacent surfaces of the first cutter body and the second cutter body of the utility model increases from small to large from top to bottom, so that the cut waste section must be smaller than the distance between the two, and no jamming will occur. The phenomenon of material hanging, and the two adjacent surfaces of the knife body are designed on both sides, which makes the structural strength of the knife edge part higher and increases the durability of the knife body.
