The split type shaping structure is operated by matching the trimming punch with the trimming anti-scrap-jumping insert and the lower die trimming insert, and the knife edge is easy to maintain after being split and worn, so that the waste is effectively prevented from jumping out upwards in the reverse direction.

Description

Die trimming knife edge assembly

Technical Field

The utility model relates to a mould field especially relates to a mould side cut edge of a knife subassembly.

Background

Now, please refer to fig. 4, which is a schematic diagram of a knife edge structure in the prior art.

However, the existing knife edge structure has the following defects:

because the middle part of the knife edge is very thin, the maintenance difficulty is high after abrasion, and the waste can jump upwards in the reverse direction due to the improper maintenance.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, one of the purposes of the utility model is to provide a die edge cutting knife edge assembly, which can solve the problem that waste materials reversely jump upwards.

The utility model discloses an one of the purpose adopts following technical scheme to realize:

the die trimming knife edge assembly comprises a trimming punch, a trimming scrap-jumping-proof insert and a lower die trimming insert, wherein the trimming scrap-jumping-proof insert and the lower die trimming insert are both in a U shape, the trimming scrap-jumping-proof insert is attached to the lower die trimming insert, and a through groove matched with the trimming punch is formed in the middle of the trimming scrap-jumping-proof insert; the middle part of the trimming scrap-jumping-preventing insert is provided with a middle bulge, and two sides of the middle bulge are provided with edge grooves; the lower die trimming insert is provided with a lower side groove.

Furthermore, the cross section of the middle bulge is triangular.

Furthermore, a flat end face is arranged on the middle bulge.

Furthermore, the scrap-jumping-preventing insert for trimming and the scrap-cutting insert for lower die are both provided with fool-proof angles.

Further, the depth of the lower side groove is larger than that of the side groove.

Compared with the prior art, the beneficial effects of the utility model reside in that:

the trimming and scrap jumping preventing insert and the lower die trimming insert are both U-shaped, the trimming and scrap jumping preventing insert is attached to the lower die trimming insert, and a through groove matched with the trimming punch is formed in the middle of the trimming and scrap jumping preventing insert; the middle part of the trimming scrap-jumping-preventing insert is provided with a middle bulge, and two sides of the middle bulge are provided with edge grooves; the lower die trimming insert is provided with a lower side groove. The split type shaping structure is operated by matching the trimming punch with the trimming anti-scrap-jumping insert and the lower die trimming insert, and the knife edge is easy to maintain after being split and worn, so that the waste is effectively prevented from jumping out upwards in the reverse direction.

The foregoing description is only an overview of the technical solutions of the present invention, and in order to make the technical means of the present invention more clearly understood, the present invention may be implemented according to the content of the description, and in order to make the above and other objects, features, and advantages of the present invention more obvious and understandable, the following preferred embodiments are described in detail with reference to the accompanying drawings.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1-3, a die trimming knife edge assembly comprises a trimming punch 10, a trimming anti-scrap-jumping insert 20 and a lower die trimming insert 30, wherein the trimming anti-scrap-jumping insert 20 and the lower die trimming insert 30 are both U-shaped, the trimming anti-scrap-jumping insert 20 is attached to the lower die trimming insert 30, and a through groove matched with the trimming punch 10 is formed in the middle of the trimming anti-scrap-jumping insert 20; the middle part of the trimming scrap-jumping-preventing insert 20 is provided with a middle bulge 21, and two sides of the middle bulge 21 are provided with edge grooves 22; the lower die trim insert 30 is provided with a lower side groove 31.
