Description

High-speed forging machine for shaping

The utility model is a kind of high-velocity forging make-up machine, belongs to the manufacturing equipment of a kind of pin, pin or nail.

Forging is the conventional process in the machining.Wherein, the clamping of wire rod is cut off it then for forging of wire rod general need earlier, again with the wire rod folder that shears to over against hold in the material nib, forge at last.Because this forging molding machine must the material nib is outer cut off wire rod holding, and has not only increased the process-cycle, has reduced production efficiency, and make this forging molding machine complex structure thus, the cost raising.

The purpose of this utility model is: design a kind of simple in structure, simplify processing technology, improve the high-velocity forging make-up machine of speed of production.

The utility model comprises the feeder, the transmission mechanism that are fixed on the base, holds material mechanism, die mechanism, the said material mechanism of holding comprises and is fixed on the rotary disk basement on the base and is installed in band on the rotary disk basement by the rotating disk of at least two material placing holes that rotating disk is by the intermittent drive mechanism drive that links to each other with transmission mechanism; Have on the rotary disk basement than material placing hole few one and corresponding with it jogger hole, a push rod and the backgauge lever mated that is driven by transmission mechanism are respectively arranged in each jogger hole.Of the present utility model holding in the jogger hole that does not have push rod on the rotary disk basement of expecting mechanism the wire rod of being sent here by feeder is arranged; when dial rotation; owing to the relative motion of rotating disk and rotary disk basement wire rod is cut off; when rotating disk went to the position of other jogger hole, die mechanism forged the wire rod in the material placing hole and finishes forging.Push rod withstands wire rod in the meantime, forges end back push rod finished product is ejected material placing hole.Preferably be evenly distributed with four material placing holes on the said rotating disk, have on the rotary disk basement and three material placing hole jogger holes corresponding, that have push rod wherein, two corresponding punch dies are arranged on the die mechanism along its circumference.This structure can make wire rod accept to forge for twice and the quality that guarantees finished product, and the push rod in another jogger hole is responsible for finished product is ejected.Intermittent drive mechanism of the present utility model can be following structure: it comprises the eccentric wheel that links to each other with transmission mechanism by power transmission shaft, and it drives a unilateral bearing by connecting rod, and further drives rotating disk.And intermittent drive mechanism with hold the material mechanism can be connected by the gear that cooperatively interacts.Said die mechanism also should have balancing weight in order to keep the steady of die mechanism operation.

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
