Abstract

The utility model discloses a forge transition die holder, including last mould and lower mould, the center correspondence of last mould and lower mould be provided with die cavity, the forging die of inserting can be placed to the inside to will insert the forging die through fixed slide wedge and be fixed in die cavity, the lower mould is provided with a plurality of guide pillar, it has a plurality of guide hole to go up the corresponding position of mould and open. The application range of the die holder is expanded, the purpose of producing medium and small high-strength material forgings on large equipment is achieved through the transition die holder, the forgings with different sizes and shapes are produced by using inserts with different specifications, and the forging transition die holder has the advantages of being simple in structure, saving a large amount of die materials and reducing die manufacturing cost.

Description

Forging transition die holder

Technical Field

The utility model belongs to the technical field of the forging mould, the utility model particularly relates to a forge transition die holder.

Background

High strength materials have high strength and high deformation resistance, requiring small area, large tonnage forming equipment. The 4000 ton electric screw press belongs to large forging equipment, has a large table top, and can produce a forged piece by being designed into a large die set on the 4000 ton equipment according to the conventional design, and the waste of die materials can be caused by using one set of die set to produce medium and small forged pieces made of high-strength materials, so that the manufacturing cost of the die is increased.

Disclosure of Invention

In order to solve the problem, the utility model provides a forge transition die holder can realize the forging of centering, small-size high strength material forging on large-scale forging equipment.

The purpose of the utility model is realized like this: the utility model provides a forge transition die holder, includes mould and lower mould, the center of mould and lower mould correspond and be provided with concave cavity, the forging die of inserting can be placed to concave cavity the inside, the lower mould is provided with a plurality of guide pillar, the corresponding position of going up the mould is opened has a plurality of guide hole, guarantees going up adjusting well of mould, lower mould.

The utility model discloses still have following technical characteristic:

1. the outer walls of the upper die and the lower die are provided with dovetail-shaped inclined planes for fixing the transition die holder on the large die frame.

2. The insert forging die is fixed in the concave cavity through the fixed wedge.

The utility model has the advantages and beneficial effect: the application range of the die holder is expanded, the purpose of producing medium and small-sized high-strength material forgings on large-scale equipment is achieved through the transition die holder, the production of forgings with different sizes and shapes is realized through insert forging dies with different specifications, and the forging transition die holder has the advantages of being simple in structure, saving a large amount of die materials and reducing die manufacturing cost.

Detailed Description

The invention is described in detail below with reference to the drawings and the following detailed description:

example 1

As shown in fig. 1-3, in this embodiment, a forging transition die holder is designed on an existing die carrier of a 4000-ton electric screw press to realize the production of a TB6 titanium alloy forging, the forging transition die holder includes an upper die 1 and a lower die 2, the centers of the upper die and the lower die are correspondingly provided with a concave cavity 5, an insert forging die can be placed in the concave cavity 5 for forming the forging, the insert forging die is fixed in the concave cavity through a fixed wedge 3, the lower die is provided with 2

guide posts

4, and 2 guide holes are formed in the corresponding position of the upper die to ensure the accurate guiding of the upper die 1 and the lower die 2. The dovetail-shaped inclined planes of 10 degrees are arranged on the front outer wall and the rear outer wall of the upper die 1 and the lower die 2 and are consistent with the inner cavity of the large die carrier, so that the transition die holder is conveniently and reliably fixed on the original large die carrier of the 4000-ton electric screw press equipment. The upper die 1 and the lower die 2 are both made of 5CrNiMo hot die steel, so that the high strength, high hardness and high toughness of the die in a hot state are ensured. The concave cavity of the embodiment can be designed in different specifications and sizes and different shapes, such as a round or square insert, so that the application range of the die holder is expanded. Has good popularization and realizes the interchangeability between a die forging hammer and an insert die on a 4000-ton electric screw press.

The application method of the forging transition die holder of the embodiment is as follows:

the first step is as follows: the transition die holder is placed into an original large die holder of a 4000-ton electric screw press, the upper die and the lower die are aligned by two guide pillars and guide holes in the transition die holder, and then the transition die holder is pressed into the large die holder by an inclined pressing plate by means of a 10-degree inclined plane on the outer side of the transition die holder.

The second step is that: and (3) placing the insert forging die into a concave cavity of the transition die holder, wherein one side of the concave cavity is a reference surface, and the other side of the concave cavity extrudes the insert forging die to the reference surface by using a fixed wedge and plays a role in fixing.

The third step: after the insert forging die is fixed, a forge piece is tried to be forged, and if the phenomenon of dislocation occurs, a spacer can be added in the same way of on-hammer adjustment.

Claims

1. The utility model provides a forge transition die holder, includes mould and lower mould, its characterized in that: the die comprises an upper die and a lower die, wherein the centers of the upper die and the lower die are correspondingly provided with a concave cavity, an insert forging die can be placed in the concave cavity, the lower die is provided with a plurality of guide pillars, and the corresponding position of the upper die is provided with a plurality of guide holes.

2. The forging transition die holder of claim 1, wherein: the outer walls of the upper die and the lower die are provided with dovetail-shaped inclined planes.

3. The forging transition die holder of claim 1 or 2, wherein: the insert forging die is fixed in the concave cavity through the fixed wedge.
