Background

Forging is a processing method which utilizes forging machinery to apply pressure on a metal blank to cause the metal blank to generate plastic deformation so as to obtain a forged piece with certain mechanical property, certain shape and certain size. The defects of as-cast porosity and the like generated in the smelting process of metal can be eliminated through forging, the microstructure is optimized, and meanwhile, because the complete metal streamline is preserved, the mechanical property of the forging is generally superior to that of a casting made of the same material.

Since the forged workpiece is generally a hard metal, the forging operation is performed by performing multiple cycles of forging operations on the surface of the workpiece along the length direction thereof to achieve a desired diameter or thickness. And in the forging process at every time, the surface of the workpiece can only deform by a small stroke amount, so that the whole forging operation needs to be performed for multiple times of circular forging, the operation efficiency is low, and time and labor are wasted.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the technical solution of the present invention with reference to the accompanying drawings and embodiments.

Referring to fig. 1-5, the multi-layer forging die comprises a die body 1, wherein the die body 1 is of a rectangular block structure, and a forging groove 11 (the shape of which is preferably an arc structure or a plane structure according to the surface shape of a forging workpiece 4) matched with the surface shape of the forging workpiece 4 is formed in the bottom of the die body 1. Because the present mode of forging is to forge 4 surperficial length directions of forging the work piece one by one, and the stroke volume of forging 4 surperficial vertical forging of edge at every turn is less, need carry out multi-level forging and just can reach required diameter or thickness, and the forging cycle is longer, and efficiency is comparatively low, consequently forge groove 11 along its length direction and set up to have the step level that a plurality of increases gradually, its purpose is through the different internal surface height of step level, once only forges multi-level to forging the work piece 4 for forging the work piece 4 has more forging deflection at the in-process of a circulation forging, reduces the forging cycle, improves forging efficiency. And a buffer mechanism used in the forging process of the die body 1 is arranged on one side of the die body 1, which is far away from the forging groove 11. Because there is the fit-up gap between mould body 1 and the forging equipment 5, after forging impact many times, cause the damage of mould body 1 easily, consequently this buffer gear can effectively alleviate mould body 1 and receive the reciprocating type forging impact force of forging equipment 5, carry out effectual guard action to mould body 1, prolong its life cycle, this buffer gear also can carry out effectual buffering to the contact of mould body 1 and forging work piece 4 simultaneously, it is great through hard contact effort to have solved both, and make the easy cracked problem of forging work piece 4.

Since the forging workpiece 4 is less likely to deform as the forging type variation increases during the forging process, the forging workpiece 4 is more resistant to deformation, and therefore, in consideration of the quality of the actual forging, the forging deformation is performed twice in the cycle of the forging process, and the forging quality can be ensured, and therefore, it is preferable that the step is two-layered, specifically, the step includes a first step a and a second step b along the forging direction (as shown by an arrow in fig. 5) of the forging workpiece 4, and as shown in fig. 5, the second step b is higher than the surface height of the first step a, and therefore, the distance from the second step b to the workpiece is larger than the distance from the first step a to the workpiece, and during the forging process, the first forging operation is performed on the surface of the forging workpiece 4 by the second step b, and after the first forging operation is completed, the entire forging die is raised, and the forging workpiece 4 moves in the direction opposite to the forging direction, the surface 100 forged by the second step b is made to correspond to the first step a, the forging die is entirely down and is forged again, the second step b performs the first forging of a new forged surface, and the first step a performs the second forging of the surface 100, thus completing the two-stage forging operation of the die during one forging cycle. The first step layer a is longer than the second step layer b, and the purpose of the first step layer a is that as the first step layer a is subjected to twice forging, a 'joint' (as shown in a part in fig. 5) exists between two forging surfaces, the tail end of the first step layer a can be extended to the part of the 'joint', the part has the function of flattening the forging, and the flatness of the surface of the forging workpiece 4 is improved.

Specifically, the buffer mechanism comprises an inverted trapezoidal block 12 arranged on the surface of the die body 1, preferably, the mounting position of the forging device 5 is set to match the shape of the inverted trapezoidal block 12 (as shown in fig. 5), a plurality of elastic members 2 are uniformly distributed in the inverted trapezoidal block 12, and the elastic members 2 are higher than the surface of the inverted trapezoidal block, so that in the forging process, the die body 1 is subjected to the reverse acting force of the surface of the forging workpiece 4, the die body 1 moves towards the forging device 5, in the moving process, the top of the elastic member 2 firstly contacts with the forging device 5, the reverse impact on the die body 1 is effectively buffered, and the problem that the forging workpiece 4 is easily broken due to the fact that the rigid contact acting force is large between the two is solved.

In order to prevent the die body 1 from being separated from the forging device 5 after being vibrated, tapered through holes (not shown in the figure) are formed in two ends of the inverted trapezoidal block 12, tapered insertion rods 3 are arranged in the tapered through holes in a matched and penetrating mode, and the die body 1 can be rapidly disassembled through the matching of the two tapered insertion rods.

The principle of the utility model is that: in the forging process, the forging workpiece 4 is subjected to multi-level forging at one time through different inner surface heights of the step layers in the die body 1, so that the forging workpiece 4 has more forging deformation in a circulating forging process, the forging period is shortened, and the forging efficiency is improved.

The die body 1 deviates from and forges 11 one side in groove and is equipped with the buffer gear who is used for die body 1 to forge the in-process, and it can effectively alleviate die body 1 and receive the reciprocating type impact force of forging equipment 5, carries out effectual guard action to die body 1, prolongs its life cycle, and this buffer gear also can carry out effectual buffering to the contact of die body 1 and forging work piece 4 simultaneously, has solved both and has great through hard contact force, and makes the easy cracked problem of forging work piece 4.
