Description

V-shaped bending die for automobile parts

Technical Field

The utility model relates to the technical field of bending equipment, in particular to a V-shaped bending die for an automobile part.

Background

Bending forming of a die is an important item for manufacturing of stamping dies, and basically bending is realized by adopting a bending punch as a bending impact part; the bending principle is that the bending forming of a product is achieved by utilizing the toughness between a bending punch and the product, and the product formed by the bending punch is easy to scratch the surface of the product due to the fact that the vertex angle of the bending punch and the surface of the product generate a large friction force, so that the surface of the product is scratched, and the appearance of the product is seriously affected.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: in order to solve the defects in the background technology, the utility model discloses a V-shaped bending die for an automobile part.

The technical scheme is as follows: the utility model provides an automobile parts V-arrangement mould of bending, includes cope match-plate pattern, sets up upper die base, lower bolster and the die holder of setting on the lower bolster on the cope match-plate pattern, the upper die base all is provided with the guide pillar all around, the die holder all cooperates all around and is provided with the guide pillar hole, the bottom surface of upper die base is provided with the V-arrangement drift, the upper surface shaping of die holder has the V-arrangement notch, just the C-arrangement notch is all cut open to the both sides of V-arrangement notch and is equipped with the C-arrangement notch, just C-arrangement notch is filled in and is equipped with the metal rod, the die holder upper surface that the V-arrangement notch corresponds distributes all around has several product locating piece.

Further, the metal rod is made of tungsten steel.

Further, the shape of the V-shaped punch matches the size of the V-shaped recess.

The utility model realizes the following beneficial effects:

according to the utility model, the metal rod is inserted into the C-shaped grooves arranged on the two sides of the V-shaped notch, so that the friction force between a product and a bent part during bending can be reduced to the maximum extent, and the coating of the product is protected from being damaged.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Examples

Referring to fig. 1-2, a V-shaped bending die for automobile parts comprises an upper die plate 10, an upper die holder 20 arranged on the upper die plate, a lower die plate and a lower die holder 40 arranged on the lower die plate 30, the guide posts 50 are arranged on the periphery of the upper die base, the guide post holes 60 are arranged on the periphery of the lower die base in a matching way, the bottom surface of the upper die holder is provided with a V-shaped punch 70, the upper surface of the lower die holder is formed with a V-shaped notch 80, the shape of the V-shaped punch head is matched with the size of the V-shaped notch, and the two sides of the V-shaped notch are both provided with C-shaped notches 90, and the C-shaped notch is internally plugged with a metal bar 100, a plurality of product positioning blocks 110 are distributed around the upper surface of the lower die base corresponding to the V-shaped notch, the V-shaped punch and the V-shaped notch are matched for use, so that the product 120 can be bent, in the bending process, the two metal rods are matched for use, so that scratches on the surface of a product can be reduced, and the surface of the product can be scratched.

In this embodiment, the metal rod is made of tungsten steel, because it has high hardness, good wear resistance, good strength and toughness, and meets the requirement of bending.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
