Abstract

The utility model discloses a two-main die and three-punching die structure of an element forming machine, which comprises two main die holes corresponding to two material returning holes, a die seat is provided with a punching sliding block which is respectively provided with an upper punching die, a middle punching die and a lower punching die independently, the center distance of the three punching dies is the same as that of the two main die holes, and the middle punching die is a spring punching sleeve die; the product is provided with one more main die and one more punching die on the basis of an ordinary cold holder, thereby being capable of processing a product with difficulty, simplifying the production operation compared with a multistation cold holder, being optimized and convenient, greatly lowering the production cost, being easy to maintain, having easy operating technology and having strong common use property with the ordinary cold holder.

Description

A kind of two main mould three punch die structures of parts shaping machine

Technical field

The utility model relates to a kind of shaping mechanism of cold headers, particularly relates to a kind of two main mould three punch die structures of forming parts process.

Background technology

Make the bolt class component in the past and be by a common mould two and hit cold headers or multistage cold former is made, present some be used for upsetting types of playing complicated screw are all somewhat expensive on the market, structure more complicated and function singleness, and operation is gone up higher to technician's specification requirement, unfavorable universal.

Summary of the invention

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of two main mould three punch die structures of adding a molding on common cold headers basis.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of two main mould three punch die structures of parts shaping machine, it comprises and the mutual two corresponding main nibs in two material returned holes, on the described die holder Punching slider is installed, three punch dies of upper, middle and lower independently are installed respectively on the Punching slider, centre-to-centre spacing between three punch dies is identical with the centre-to-centre spacing of two main nibs, and described middle punch die is that spring is towards cover die.

The beneficial effects of the utility model are: this product is added a main mould and a punch die on common common cold headers basis, thereby satisfied the processing of difficulty product, simplify than multistage cold former in the production operation, it is convenient to optimize, production cost reduces greatly, maintaining is easy, and operating technology is also simple, and the shared property of mould and common cold headers is strong.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a punch die structure schematic diagram of the present utility model;

Fig. 2 is a main nib structural representation of the present utility model.

The specific embodiment

With reference to Fig. 1, Fig. 2, a kind of two main mould three punch die structures of parts shaping machine, it comprises and the mutual two corresponding

main nibs

61,62 in two material returned holes, on the described die holder 1 Punching slider 2 is installed, three punch dies of upper, middle and lower 3,4,5 independently are installed respectively on the Punching slider 2, centre-to-centre spacing between three punch dies 3,4,5 is identical with the centre-to-centre spacing of two

main nibs

61,62, and described middle punch die 4 is that spring is towards cover die.

The operation principle of this product is: 3 of upper trimming dies play the once compression effect of waylaying and rob, and blank are stamped into the distortion first time of carrying out material in the first main mould; Two punch dies 4 be spring towards cover die, mainly act as and be raised to a main mould position and receive in a main mould through the blank of punching press, contain and entangle, be delivered to two main mould positions by moving downward of Punching slider 2 then, blank is delivered in the two main moulds, and is done a punching press of head; The 5 main effects of three punch dies are to do the last moulding punching press of product head.

This product is added a main mould and a punch die at a traditional mould two towards cold headers, thereby this machine of making can increase a cold-heading part upsetting distortion number of times.Can produce complicated parts, part that multistage cold former is produced and multistage cold former are difficult for the part of production.The method is than traditional multistage cold former designs simplification, and function is basic identical, and more convenient operation is not high to operating personnel's specification requirement, has especially solved the production difficult problem of ultrashort extra small line series products.

Claims

1. two of a parts shaping machine main mould three punch die structures, it is characterized in that: comprise and the mutual corresponding two main nibs (61,62) in two material returned holes, Punching slider (2) is installed on the described die holder (1), three punch dies of upper, middle and lower (3,4,5) independently are installed respectively on the Punching slider (2), centre-to-centre spacing between three punch dies (3,4,5) is identical with the centre-to-centre spacing of two main nibs (61,62), and described middle punch die (4) is that spring is towards cover die.
