Abstract

The present invention relates to multifunctional part forming mechanism without grab. In the hollow upsetting and material holding demolding mechanism, these is one spike mechanism in the material pushing position and the spike is pointed straightly to the main mold and locked onto the spike rod. The material holding mechanism has demolding cam, bearing, lever, tension spring, knuckle bearing, material supporting oscillator and material holding knife. The upsetting ram mechanism includes female mold seat with two main molds and ram seat with three ram molds. The material cutting and conveying mechanism comprises material cutting rod and material cutter with one small hole on the end to cut material and screw on the other end for connection to the material cutting rod. The present invention may be used in machining various complicated nail-shaped parts.

Description

Multifunctional part forming mechanism without grab

Technical field

The present invention relates to a kind of part forming, especially a kind of multifunctional part forming mechanism without grab.

Background technology

The multistage cold former of plain bolt and the hollow machine of processing tubular rivet are made in rammer in the past, can only process some fairly simple screws and semi-hollow screw etc., for the hollow nail of processing belt stepped screw or many steps and complicated any hollow nail, cold machine of common multidigit and hollow machine are to be difficult to realize, on present hollow nail manufacturing industry, major part all is to process by punch press, lathe and common hollow machine, the low and also increase exponentially of cost of efficient.In the market some types of playing complicated screw and tubular rivet that is used for upsetting are all somewhat expensive, and structure is more complicated and function singleness also, and operation go up higher to technician's specification requirement, unfavorable popularizing.A kind of multifunctional part forming mechanism without grab that can process the spike part of multiple complexity of purpose design of the present invention.

Summary of the invention

A kind of multifunctional part forming mechanism without grab, its structure is by body and be located at drift up and down upsetting mechanism, blank and send that feeding clip mechanism is beaten by blank mechanism, hollow rammer, the one ejector pin mechanism is formed on the body, the liftout position of beating the material folding mould emptier in hollow rammer is provided with the one ejector pin mechanism, and thimble leads directly to main mould, thimble is locked together with the thimble rod, make corresponding sports, in feeding clip mechanism, be provided with demoulding cam, bearing, lever, extension spring, oscillating bearing, retainer goods of furniture for display rather than for use, clip feed blade; The described drift mechanism that upsets up and down is provided with two main moulds by the former seat, is divided into being arranged above and below, and punch holder is arranged three punch dies from top to bottom; Described blank and send blank mechanism, by cut the material bar, cutter is formed, an end that is used for cutting off blank on the cutter is drilled with an aperture, this hole is decided by the size of part, the other end is locked to cut with bolt expects on the bar.

The present invention has following advantage:

1, the part transmission between the upsetting station has adopted no clamp to send the mode of blank, and part transmission and rammer are beaten and can be utilized moving up and down of drift to realize simultaneously.

2, mould emptier adopts the lever form, makes the retainer goods of furniture for display rather than for use drive clip feed blade and does steadily side-to-side movement reliably.

3, make the blank direct forming in the mould thimble that is delivered to main mould, common multistage cold former and tubular rivet machine are upset when beating step and many steps and hollow parts before having solved, blank is clipped in and is difficult in the thimble ejecting, the shortcoming that fault is many, assembling is complicated, and can easily finish owing to upset when making hollow nail and many stepped screws, stressed heavier, press from both sides out being enclosed within the blank that is difficult for ejecting in the mould thimble that is used to be shaped, the demoulding, liftout, material folding are finished synchronously.
