Abstract

The invention discloses a flattening die for T-shaped iron. The flattening die comprises an upper die and a lower die which are mutually matched. The upper die comprises an upper die plate and an upper flattening die body mounted inside the lower end of the upper die plate. The lower die comprises a lower die plate, a lower flattening die body and an ejector pin, the lower flattening die body is mounted inside the lower die plate, and the ejector pin is mounted in the lower flattening die body. The top of the lower flattening die body is recessed to form a T-shaped groove which penetrates the bottom of the lower flattening die body. The ejector pin extends into the lower portion of the T-shaped groove through the bottom of the lower flattening die body. The bottom surface of the upper flattening die body is attached to the top surface of the lower flattening die body. The upper portion of the T-shaped groove forms a closed pressing cavity. By the flattening die for the T-shaped iron, production efficiency is improved, production cycle is shortened, machining cost is reduced, and raw materials are saved.

Description

A kind of T iron flattens mould

Technical field

The present invention relates to a kind of mould, relate in particular to a kind of T iron and flatten mould.

Background technology

It is inhomogeneous because walking to expect during more than 80 T iron products at forging and stamping diameter that common T iron flattens mould, with problems such as technique bias, make excircle eccentricity degree and the cylindricity of T iron not reach requirement, therefore conventionally will go up lathe processing just can make product up to standard, although the method for lathe processing can make circle product external reach higher precision, will waste a lot of manpower and materials, and efficiency is low aspect machined, waste of material is serious, produces girth.

Summary of the invention

The object of this invention is to provide a kind of T iron and flatten mould, solved the problem that efficiency is low, waste of material serious, produce girth.

For achieving the above object, the invention provides a kind of T iron and flatten mould, comprise the upper die and lower die that cooperatively interact, described patrix comprises cope match-plate pattern and is arranged on the flattening patrix of inside, described cope match-plate pattern lower end; Described counterdie comprises lower bolster, is arranged on the flattening counterdie in described lower bolster and is arranged on the thimble in described flattening counterdie, described flattening counterdie top depression forms a T-shaped groove, described T-shaped groove runs through the bottom of described flattening counterdie, described thimble stretches into the bottom of described T-shaped groove from the bottom of described flattening counterdie, the end face laminating of the bottom surface of described flattening patrix and described flattening counterdie, and the top of described T-shaped groove forms the compression chamber of a sealing.

Preferably, described cope match-plate pattern bottom notch forms mounting groove, and the center of described cope match-plate pattern is also provided with the through hole being communicated with described mounting groove, and described flattening patrix is arranged in described mounting groove, and the bottom surface of described flattening patrix and the bottom surface of described cope match-plate pattern concordant.

Preferably, the center of described lower bolster is provided with installing hole, and described flattening counterdie is arranged in described installing hole, and the end face of described flattening counterdie and the end face of described lower bolster concordant.

Compared with prior art, T iron of the present invention flattens mould due to the compression chamber of a sealing of top formation of described T-shaped groove, can make T iron product in the process of forging and stamping, walk material evenly, and T iron excircle eccentricity degree and the cylindricity produced all can reach requirement, avoid machining process, thereby not only improved production efficiency, shortened the production cycle, reduce machined cost, but also saved raw material.

By following description also by reference to the accompanying drawings, it is more clear that the present invention will become, and these accompanying drawings are used for explaining embodiments of the invention.

Accompanying drawing explanation

Fig. 1 is the cutaway view that T iron of the present invention flattens mould.

The specific embodiment

With reference now to accompanying drawing, describe embodiments of the invention, in accompanying drawing, similarly element numbers represents similar element.

Please refer to Fig. 1, described T iron flattens mould and comprises the upper die and lower die that cooperatively interact, and wherein, described patrix comprises cope match-plate pattern 1 and is arranged on the flattening patrix 2 of described cope match-plate pattern 1 inside, lower end; Described counterdie comprises lower bolster 3, is arranged on the flattening counterdie 4 in described lower bolster 3 and is arranged on the thimble 5 in described flattening counterdie 4, the end face laminating of the bottom surface of described flattening patrix 2 and described flattening counterdie 4, and described flattening patrix 2, flattening counterdie 4 and thimble 5 surround the compression chamber 6 that forms a sealing.

Described cope match-plate pattern 1 bottom notch forms mounting groove 11, and described flattening patrix 2 is arranged in described mounting groove 11, and the bottom surface of described flattening patrix 2 is concordant with the bottom surface of described cope match-plate pattern 1.The center of described cope match-plate pattern 1 is also provided with the through hole 12 being communicated with described mounting groove 11.The center of described lower bolster 3 is provided with installing hole 31, and described flattening counterdie 4 is arranged in described installing hole 31, and the end face of described flattening counterdie 31 is concordant with the end face of described lower bolster 4.Described flattening counterdie 4 top depression form a T-shaped groove 41, and described T-shaped groove 41 runs through the bottom of described flattening counterdie 4, and described thimble 5 stretches into the bottom of described T-shaped groove 41 from the bottom of described flattening counterdie 4, and described compression chamber 6 consists of the top of described T-shaped groove 41.

In sum, because the top of described T-shaped groove 41 forms the compression chamber 6 of a sealing, can make T iron 7 in the process of forging and stamping, walk material evenly, and T iron 7 excircle eccentricity degree and the cylindricity produced all can reach requirement, avoid machining process, thereby not only improved production efficiency, shortened the production cycle, reduce machined cost, but also saved raw material.

Invention has been described for above combination most preferred embodiment, but the present invention is not limited to the embodiment of above announcement, and should contain the various modifications of carrying out according to essence of the present invention, equivalent combinations.
