Description

Multi-station drawing die insert capable of preventing multiple materials from cracking

Technical Field

The utility model relates to a station mould technical field especially relates to a multistation drawing die prevents that many materials are beaten and is split and insert.

Background

With the rapid development of the automobile industry, the production of stamping parts increasingly uses automatic feeding lines and presses. The multi-station press is typical automatic production equipment, has high production rate and high safety, occupies less production personnel, has low stamping production cost, can cause the problem of mistaken feeding of the automatic press, and has higher incidence rate of die damage accidents than a single-process die.

The existing U-shaped part die insert is unreasonable in design, if more than 2 sheets are mistakenly fed in production, the die insert and a die body are cracked, the upper die drawing U-shaped insert is single, the partitioning is unreasonable, the blocking keys are arranged on one side, if more than 2 sheets are mistakenly fed, the insert and the die body are cracked, if more than 2 sheets are mistakenly fed in, the insert is cracked in the drawing process due to the fact that 2 sheets are the whole U-shaped insert, the insert is cracked by the sheets, and due to the fact that only the key is arranged on the right side, the insert is extruded to the right after being cracked, and if the maximum plastic deformation amount of the single blocking key is smaller than the moving amount of the insert after being cracked, cracking or scrapping of the upper die base or high-cost cracking repair can be possibly caused. Therefore, the insert for preventing multiple materials from cracking of the multi-station drawing die is provided.

SUMMERY OF THE UTILITY MODEL

The utility model provides a to prior art not enough, the utility model provides a multistation drawing die prevents that many materials are beaten and are split and insert, has overcome prior art not enough, aims at solving the problem in the background art.

In order to achieve the above object, the utility model provides a following technical scheme: the multi-material cracking-preventing insert for the multi-station drawing die comprises an upper die base, wherein a drawing insert is installed on the upper die base and is a U-shaped part die insert, the drawing insert comprises a first drawing insert and a second drawing insert, the first drawing insert and the second drawing insert are movably installed on the upper die base and are connected in a splicing mode, a splicing seam is formed between the first drawing insert and the second drawing insert, and a blocking device used for blocking the first drawing insert and the second drawing insert from moving is installed on the upper die base.

As a preferred technical scheme of the utility model, blocking device is including keeping off key one and keeping off key two, keep off key one and keep off key two and be located respectively draw insert one with draw one side of inserting two and keeping away from each other.

As a preferred technical scheme of the utility model, the width of fender key one with keep off key two is-millimeter.

As an optimized technical scheme of the utility model, keep off key one with keep off key two and make by the material that has plastic deformation ability.

The utility model has the advantages that:

the original single insert is changed into the splicing of a drawing insert I and a drawing insert II, and the position strength of the splicing seam of the inserts is ensured. If a plurality of sheets are delivered by mistake, after the splicing between the drawing insert I and the drawing insert II is extruded in a large quantity, the drawing insert I and the drawing insert II respectively move towards two sides to extrude the blocking key I and the blocking key II, so that the insert cannot be cracked, the blocking key I and the blocking key II have better plasticity, the width is reduced by extrusion, and therefore the die body is protected from being cracked, the service life of the drawing insert is prolonged, and the maintenance cost of the die is greatly reduced.

The utility model discloses the protection die body is not cracked, improves the life that the drawing was inserted, and greatly reduced mould cost of maintenance is convenient for make, easy operation, reasonable in design easily promotes.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the multi-material cracking-preventing insert for the multi-station drawing die comprises an upper die base 5, wherein a drawing insert is installed on the upper die base 5, the drawing insert is a die insert of a U-shaped part, the drawing insert comprises a first drawing insert 3 and a second drawing insert 4 which are movably installed on the upper die base 5, the first drawing insert 3 and the second drawing insert 4 are connected in a splicing mode, a splicing seam is formed between the first drawing insert 3 and the second drawing insert 4, and a blocking device used for blocking the first drawing insert 3 and the second drawing insert 4 from moving is installed on the upper die base 5.

The blocking device comprises a first blocking key 1 and a second blocking key 2, and the first blocking key 1 and the second blocking key 2 are respectively positioned on one sides, far away from each other, of a first drawing insert 3 and a second drawing insert 4. In addition, the widths of the first blocking key 1 and the second blocking key 2 are 25-30 mm, the first blocking key 1 and the second blocking key 2 are made of materials with plastic deformation capacity, plasticity exists without heat treatment, the deformation space is large, the plasticity of the first blocking key 1 and the second blocking key 2 is good, and the widths of the first blocking key 1 and the second blocking key 2 are reduced by extrusion of the first drawing insert 3 and the second drawing insert 4, so that the die body is protected from being cracked, and the service life of the drawing insert is prolonged.
