Description

Staggered cutting insert for stamping die
Technical Field
The utility model relates to the field of stamping dies, in particular to a miscut insert for a stamping die.
Background
The stamping die is a special process equipment for processing metal or nonmetal materials into parts or semi-finished products in cold stamping processing, and is called as a cold stamping die and commonly called as a cold stamping die. Stamping is a press working method in which a die mounted on a press is used to apply pressure to a material at room temperature to cause separation or plastic deformation thereof, thereby obtaining a desired part.
After the die completes the stamping operation, the excess sheet material on the corners of the die needs to be removed, so that the die forms a part with a preset shape, and when the excess sheet material is removed, the excess sheet material is generally removed by cutting or secondary stamping.
The applicant researches and discovers that the existing die scrap removal method generally adopts a cutting or secondary stamping mode, so that secondary processing is required, the operation is complex during processing, and the stamped die is easy to damage.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provides a miscut insert for a stamping die.
The purpose of the utility model is realized by the following technical scheme: the utility model provides a cross cutting inserts for stamping die, includes stamping die and inserts the cutter, the stamping die is last to be equipped with the cutter of inserting, the sword income of the cutter of inserting is the thick end of stock and the surplus sum of 2mm, wherein: the insert cutter comprises an insert correcting block and a side insert correcting block, wherein the cutter crossing area of the insert correcting block and the side insert correcting block is 5mm, a 3mm gap is reserved between the insert correcting block and the side insert correcting block, the cutting edge thickness of the edge passing position of the insert correcting block and the side insert correcting block is 7mm, a recess is arranged on the insert correcting block, the cross section of the recess is of a round angle type structure, and the insert correcting block is in smooth transition between the front edge part and the rear trimming part.
Further, when the angle between the correcting insert and the side insert is less than or equal to 30 degrees, the correcting insert is firstly edged.
Further, when the angle between the correcting insert and the side insert is larger than 30 degrees, the side insert is firstly cut in.
Compared with the prior art, the utility model has the following advantages:
during the use, directly carry out the miscut to it after the punching press action is accomplished and cut the limit to make stamping equipment accomplish the operation of cutting the limit when protecting the finished piece, avoid causing the problem of destruction to the good mould of punching press, the crossing sword region of inserting is repaiied to the positive and side of inserting moreover is 5mm, leaves the 3mm clearance between inserting is repaiied to the positive and side, can effectively prevent to repair and insert and side and repair and to inlay and bump between inserting.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described below with reference to the accompanying drawings and examples.
Example one
As shown in fig. 1 to 4, the embodiment discloses a miscut insert for a stamping die, which includes a stamping die 1 and an insert cutter 2, wherein the insert cutter 2 is arranged on the stamping die 1, the cutting edge of the insert cutter 2 is the sum of the blank thickness and the 2mm allowance, the insert cutter 2 includes a front insert 3 and a side insert 4, the intersection area of the front insert 3 and the side insert 4 is 5mm, a 3mm gap is left between the front insert 3 and the side insert 4, the cutting edge thicknesses of the passing edge of the front insert 3 and the side insert 4 are both 7mm, a recess 5 is arranged on the front insert 3, the cross section of the recess 5 is in a fillet structure, and the front edge of the front insert 3 is in smooth transition with the rear edge.
When the angle between the correcting insert 3 and the side correcting insert 4 is less than or equal to 30 degrees, the correcting insert 3 is firstly cut in.
Example two
As shown in fig. 1 to 4, the embodiment discloses a miscut insert for a stamping die, which includes a stamping die 1 and an insert cutter 2, wherein the insert cutter 2 is arranged on the stamping die 1, the cutting edge of the insert cutter 2 is the sum of the blank thickness and the 2mm allowance, the insert cutter 2 includes a front insert 3 and a side insert 4, the intersection area of the front insert 3 and the side insert 4 is 5mm, a 3mm gap is left between the front insert 3 and the side insert 4, the cutting edge thicknesses of the passing edge of the front insert 3 and the side insert 4 are both 7mm, a recess 5 is arranged on the front insert 3, the cross section of the recess 5 is in a fillet structure, and the front edge of the front insert 3 is in smooth transition with the rear edge.
When the angle between the correcting insert 3 and the side insert 4 is more than 30 degrees, the side insert 4 is firstly cut in.
The working process and principle of the utility model are as follows: after the stamping die 1 finishes stamping the workpiece, the positive trimming insert 3 and the side trimming insert 4 are pushed according to a preset proper sequence through a pushing device, so that an insert cutter can cut redundant rim charge of the workpiece, and when the positive trimming insert 3 and the side trimming insert 4 meet the workpiece, a clearance 5 designed in a fillet shape and the lifting front edge part of the positive trimming insert 3 and the rear trimming part of the positive trimming insert 4 are in smooth transition, so that collision between the positive trimming insert 3 and the side trimming insert 4 can be avoided, and the wrong-cutting insert also has the advantages of simple structure, convenience in operation and easiness in implementation.
