Abstract

The invention discloses a multipurpose cross wedge rolling die. The multipurpose cross wedge rolling die comprises an upper die body and a lower die body. The upper die body and the lower die body are respectively composed of a plurality of modules. The modules are movably installed on an upper working roll and a lower working roll of a cross wedge rolling machine. Hole pattern sizes of the die can be determined according to the actual sizes of machined products, namely, hole patterns of a new die are designed according to changed modules of shaft parts to be machined and an original die, and the shaft parts to be machined are produced. The multipurpose cross wedge rolling die has the advantages of being low in production cost, short in design and production time, small in formed number, and capable of being widely applied to manufacturing the shaft parts and improving economic benefits of enterprises.

Description

The cross wedge rolling die of one module multiple usages

Technical field

The present invention relates to a kind of mould, be specifically related to a kind of cross wedge rolling die of producing the one module multiple usages of many sizes.

Background technology

Cross wedge rolling is a kind of axial workpiece New Forming Process, new technology, and it is metallurgy rolling and the emerging technology of intersecting with development of machinery forging and stamping.Its operation principle is the wedge shape mould being contained on homodromal roll with two, drives rolled piece rotation under the protruding role of wedge shape of wedge shape mould, and makes blank produce continuous and local small deformation, is finally rolled into the various Step Shafts of wedge shape pass.Wedge cross rolling deformation is under die pressure effect, and the surface contacting with mould from rolled piece starts, and along with the increase of drafts, plastic deformation is infiltration inwards constantly, until inside also produces plastic deformation.Along with the rotation of mould, such distortion is by continuous on the whole section of rolled piece.At axial direction, the broadening along with wedge shape moves wedge cross rolling deformation gradually, and rolled piece middle part is deformed area when wedging starts, and deformed area is divided into two subsequently, and interlude becomes deformed area, and expands gradually.At present, each forms general cross wedge rolling die by some, and a secondary mould correspondence can only be produced a product, when product size changes or when two products approach very much, all needs to design a new mold separately, could meet Production requirement.For a long time like this, the rolled piece of exploitation different length, all obtains exploitation and composition cross wedge rolling die again, increases enterprise's production cost and construction cycle, affects enterprise and better develops.

Summary of the invention

The object of the present invention is to provide the cross wedge rolling die of the one module multiple usages that a kind of design time is short, production cost is low, this mould can be changed the module needing according to the different position of product size, improves the utilization rate of identical product same area module.

For achieving the above object, the cross wedge rolling die of one module multiple usages of the present invention, comprises upper and lower die ontology, and described upper and lower die ontology forms by some modules, and each module activities is arranged on the upper and lower working roll of cross wedge rolling machine.

Some described modules comprise the first module, the second module, the 3rd module, four module and the 5th module.

Adopt after technique scheme, because described upper and lower die ontology is comprised of several modules, each module activities is arranged on the working roll of cross wedge rolling machine.When production circular section is identical, length is different axle class part, only mould piece corresponding to different positions need to be replaced with to the module that axle class part to be processed needs, according to module and original Design of Dies new die pass of axle class part change to be processed, can complete the production of axle class part to be processed.Take this structure, on the one hand, simplify the Design and manufacture of cross wedge rolling die, fully realize one module multiple usages; On the other hand, be reduced to mould quantity, reduce production mould expense and construction cycle, greatly save production cost, increase economic efficiency.

Accompanying drawing explanation

Fig. 1 is the cross wedge rolling die structural representation of one module multiple usages of the present invention;

Fig. 2 is mold body construction schematic diagram of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing, the cross wedge rolling die of one module multiple usages of the present invention is described further;

From Fig. 1, Fig. 2, a kind of cross wedge rolling rolled piece mould of the present invention, comprises upper and lower die ontology 1, and described upper and lower die ontology 1 forms by some modules, and each module activities is arranged on the upper and lower working roll 2 of cross wedge rolling machine.

Use when of the present invention, according to the size of axle class part actual size to be processed, determine the module piece number of upper and lower die ontology 1, then each module is installed on the upper and lower working roll 2 of cross wedge rolling machine, form a complete upper and lower die ontology 1, can produce the axle class part of different size.

The technology of the present embodiment is mainly solved by the following technical programs: by the four module 14 of different size and the removable position of the upper and lower die ontology 1 of the 5th module 15 formation; The two ends of four module 14, the 5th module 15 are connected with the upper and lower working roll 2 of cross wedge rolling machine with manner.

In the present embodiment, by changing the length of four module 14 and the 5th module 15, meet the requirement of different axle class part sizes to be processed, thereby produce the axle class part of different size, i.e. one module multiple usages, one-shot forming, thus simplified Design of Dies and manufacture; The first module 11, the second module 12, the 3rd module 13 can Reusabilities, reduced mould quantity, and convenient manufacture is cost-saving.

Claims

1. a cross wedge rolling die for one module multiple usages, comprises upper and lower die ontology (1), it is characterized in that: described upper and lower die ontology (1) forms by some modules, and each module activities is arranged on the upper and lower working roll (2) of cross wedge rolling machine.

2. the cross wedge rolling die of one module multiple usages according to claim 1, is characterized in that: some described modules comprise the first module (11), the second module (12), the 3rd module (13), four module (14) and the 5th module (15).
