Abstract

The utility model relates to a multi-station bolt cold header, which comprises master molds and punching molds, wherein the number of the master molds is three, and the number of the punching molds is five; a first punching mold corresponds to a first master mold, a second and a third punching molds correspond to a second master mold, a fourth and a fifth punching molds correspond to a third master mold. As three master molds and five punching molds are adopted, that is to say, one punching mold is respectively increased on the second and the third master molds, compared with a three-mold three-stroke cold holder, the number of the master molds is not increased, and the capability of processing complex parts is increased, so the processing effect of the utility model is far exceed three-mold three-stroke cold holders and four-mold four-stroke cold holders, and even reaches the processing effect of five-mold five-stroke cold holders, and the cost of molds can not exceed the four-mold four-stroke cold holders. The multi-station cold holder can be improved on the basis of original machine tools, and the improvement is simple and convenient.

Description

Multistation bolt Cold header

Technical field

The utility model relates to a kind of bolt Cold header, relates in particular to a kind of multistation bolt Cold header.

Background technology

The product that present known multistation bolt Cold header is produced cooperates with punch die simply because of main mould, the product of making has certain limitation, a lot of specialities, get out of a predicament or an embarrassing situation above three layers such as bolt head, perhaps the tube reducing of cross section diameter ratio surpasses 0.5 under the bolt head, and the product of the middle all-pass of parts, all need the instrumentation lathe to carry out secondary operations; If bolt head slows down speed of production, cost up for eccentric parts more need punch press to carry out whole head.If adopt to increase mould mode, can increase manufacturing cost because of the increase of mould again, simultaneously, the product precision also falls sharply because of needs repeatedly are installed.

The utility model content

The purpose of this utility model is at the problems referred to above, provides a kind of and transforms conveniently, do not need to increase main mould and reach the multistation bolt Cold header that can make the complex product effect again.

For this reason, multistation bolt Cold header of the present utility model comprises main mould and punch die, and described main mould is three, and punch die is five; The corresponding first main mould of first punch die wherein, the corresponding second main mould of second, third punch die, corresponding the 3rd main mould of the 4th, the 5th punch die.

Owing to adopt three main moulds and five punch dies, promptly each correspondence increases a punch die on second, third main mould, therefore for three moulds, three strokes, its main modulus amount does not have to increase and the ability of processed complex part has increased, three moulds three that surpass far away are towards Cold header, also surpass four moulds four towards Cold header, even reach the processing effect of five moulds five, and die cost can not dashed above four moulds four towards Cold header; This multistation Cold header can be improved on the basis of original lathe, and its improvement is simple and convenient.

Described first punch die can be fixedly installed in decompressor, and second, third punch die and the 4th, the 5th punch die are installed on decompressor by a slide plate; Described slide plate moves between two stations, makes described second punch die or the respectively corresponding second main mould of the 3rd punch die at these two stations, then respectively corresponding the 3rd main mould of described the 4th punch die or the 5th punch die.Adopt this structure, second, third punch die and the 4th, the 5th punch die can same moved further, and it is simple in structure.Moving then of described slide plate can be driven by a connecting rod swing structure.

Also can be that first punch die is fixedly installed in decompressor, and second, third punch die is installed on decompressor by first slide plate, the 4th, the 5th punch die be installed on decompressor by second slide plate; Described first slide plate moves between two stations, makes described second punch die or the respectively corresponding second main mould of the 3rd punch die at these two stations; And described second slide plate also moves between two stations, makes described the 4th punch die or respectively corresponding the 3rd main mould of the 5th punch die at these two stations.Adopt this structure, second, third punch die and the 4th, the 5th punch die can move respectively, and its different combination can finish that three moulds three dash, three functions that moulds four dash and three moulds five dash, and can realize a tractor serves several purposes.Moving then of described first slide plate, second slide plate can be driven by two connecting rod swing structures respectively.

The described first, second, third and the 4th main mould can be arranged side by side by along continuous straight runs.
