Abstract

The utility model relates to a hot punching and edge cutting mould of forgeable piece, which belongs to the field of plastic forming and mainly comprises an upper mould plate, an edge cutting male mould, a punching head, an edge cutting female mould and a lower mould seat, wherein, the edge cutting male mould and the punching head are fixedly connected with a holder. When in operation, the punching head punch round holes on the forgeable piece under the action of a pressing machine. When the male mould and the forgeable piece contacting at the same time, the edge cutting female mould make the edge cutting; when the slide block descending to the lower dead point, the edge cutting is completed; thus the purpose of edge cutting and hole punching at the same time can be realized. The utility model is integrated with hole punching and edge cutting functions and can complete the hole punching and the edge cutting at one time. Compared with the prior art of compound mould with hole punching and edge cutting function, the utility model can eliminate the parts of U shape plate and tension rod and has the advantages of simple structure, convenient loading and unloading, high working efficiency and low costs.

Description

Novel hot piercing, shaving die

(1) technical field

The utility model relates to a kind of hot piercing, shaving die of forging, belongs to the plastic forming field.

(2) background technology

At present, at forging industry, the edge-cutting and hole-punching of circle class forging with holes mainly contains two kinds of devices; A kind of is the edge-cutting and hole-punching compound die, and this mould structure complexity, processing difficulties, process-cycle loading and unloading long, mould are more difficult time-consuming; Another kind method is to adopt two covering devices, finishes on two equipment, and the method need design two molds, and a cover is edger, and a cover is perforating die, production cost height.

(3) summary of the invention

The utility model proposes a kind of punching, side cut function of integrating at the deficiencies in the prior art, and make punching, cut edge and once to finish, and rational in infrastructure, easy to use, the simple novel hot piercing of mould handling, shaving die.

The utility model is finished by following technical measures.

This device is made up of cope match-plate pattern, side cut punch, drift, trim die, die shoe, wherein, side cut punch, drift be fixedly connected on cope match-plate pattern below, trim die is fixedly connected on the die shoe, trim die inner edge and side cut punch outer rim are complementary, and die shoe is fixedly connected on the fixture.

Described cope match-plate pattern, die shoe are made by steel-casting.

Described side cut punch, trim die and drift are made by mould steel.

The utility model is connected side cut punch, drift on the cope match-plate pattern by screw, for connecting power, cope match-plate pattern is connected with slide block on the forcing press, trim die is connected on the die shoe by screw, die shoe is installed on the workbench of forcing press, and there is the forging discharging opening front of die shoe or back.During work, drift will be gone out circular hole on the forging under the effect of forcing press, and when punch contacted with forging, trim die was cut edge; When slide block down during to bottom dead centre, side cut is finished; Thereby realize side cut, the one step completed purpose of punching.The utility model with punching, side cut function in one, make punching, cut edge and once finish, compare with the punching side cut composite die of prior art, saved parts such as U-shaped plate and pull bar, have simple in structure, easy to loading and unloading, high efficiency, advantage such as with low cost.

(4) description of drawings

Accompanying drawing is a structural representation of the present utility model.

Wherein: 1, cope match-plate pattern; 2, soket head cap screw; 3, die shoe; 4, side cut punch; 5, drift; 6, trim die.

(5) specific embodiment

Embodiment: as shown in drawings, side cut punch 4, drift 5 are connected on the cope match-plate pattern 1 by soket head cap screw 2, and trim die 6 is connected on the die shoe 3 by soket head cap screw 2.Cope match-plate pattern 1, die shoe 3 are steel-casting, and side cut punch 4, trim die 6, drift 5 are made by mould steel, and manufacturer's standard is pressed the universal mold manufacturer's standard.

During use, forging after the forging (temperature 〉=800 ℃) is put on the trimming and piercing die, starting pressure machine button, slide block drive cope match-plate pattern 1 and punch 4, drift 5 move downward, and drift at first contacts the punching recess of forging, after punching recess has just dashed, punch 4 contacts with forging and cuts edge, when slide block down during to bottom dead centre, the action of cutting edge is finished, and slide block is up.The side opening of die shoe 3 takes out in order to the forging with completion of processing.

Claims

1, a kind of novel hot piercing, shaving die, it is characterized in that, mainly form by cope match-plate pattern, side cut punch, drift, trim die, die shoe, wherein, side cut punch, drift be fixedly connected on cope match-plate pattern below, trim die is fixedly connected on the die shoe, and trim die inner edge and side cut punch outer rim are complementary, and die shoe is fixedly connected on the fixture.
