Abstract

The utility model discloses a T-shaped iron flattening mold. The T-shaped iron flattening mold comprises an upper mold and a lower mold which are matched with each other, wherein the upper mold comprises an upper mold plate and a flattening upper mold arranged at the interior of the lower end of the upper mold plate; the lower mold comprises a lower mold plate, a flattening lower mold arranged inside the lower mold plate and an ejector pin arranged inside the flattening lower mold; a T-shaped groove is formed in a dent at the top of the flattened lower mold; the T-shaped groove penetrates through the bottom of the flattening lower mold; the ejector pin stretches into the lower part of the T-shaped groove from the bottom of the flattening lower mold; the bottom surface of the flattening upper mold is bonded with the top surface of the flattening lower mold; the upper part of the T-shaped groove forms a closed compressing cavity. According to the T-shaped iron flattening mold disclosed by the utility model, the production efficiency is improved, the production period is shortened, the machining cost is reduced, and the raw materials are further saved.

Description

A kind of T iron flattens mould

Technical field

The utility model relates to a kind of mould, relates in particular to a kind of T iron and flattens mould.

Background technology

It is inhomogeneous because walking to expect when 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.

Utility model content

The purpose of this utility model is to provide a kind of T iron and flattens mould, has solved the problem that efficiency is low, waste of material serious, produce girth.

For achieving the above object, the utility model provides a kind of T iron to flatten mould, comprises the upper die and lower die that cooperatively interact, and 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 utility model flattens the compression chamber of mould due to 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 utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.

Accompanying drawing explanation

Fig. 1 is the cutaway view that the utility model T iron flattens mould.

The specific embodiment

With reference now to accompanying drawing, describe embodiment of the present utility model, 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 is made up 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.

In conjunction with most preferred embodiment, the utility model is described above, but the utility model is not limited to the embodiment of above announcement, and should contains the various modifications of carrying out according to essence of the present utility model, equivalent combinations.
