Abstract
The invention discloses an all fiber forging technology of a cross shaft forging piece. The all fiber forging technology of the cross shaft forging piece comprises the following steps: (1) the first fire, heavy pressing and upsetting-stretching of a blank: upsetting vertical materials by an upper flat anvil and a lower flat anvil; (2) the second fire, forming: forging through and compacting the blank, then finishing all directions of the blank, and pressing 90 degrees triangular pressing shoulders in from the upper face and the lower face, finally turning 90 degrees to form opposite grooves; (3) the third fire, forming in a mould: stretching the blank for forming four sections of small circles to the size of the forging piece. The technology is low in skill requirement of a worker, convenient to operate and high in production efficiency; the loose tooling forging is accurate in shape and high in size accuracy, so that the accessorial blocks of the technology are few and the machining allowance is small; an all fiber forging method is used, so that abundant raw materials are saved and the machinery machining working hours are reduced; by means of the complete and streamlined tissue fiber, the mechanical property of the products is greatly improved and the service life is increased.
Description
Technical field
The present invention relates to Forging Technology, be specifically related to the forging technique of full fiber of cross axle forging.
Background technology
Cross axle is the strength member on crossheading type universal coupling, and design requires to use flat-die forging to shape,
Check and accept by JB/T5000.8-2007 standard.Owing to using the FMT of Whole fiber, user does not propose spy
Other performance requirement.Some producers used when forging and were swaged into cake class or square class blank, so in the past
Part shape is become afterwards with machine tooling.The most both waste a large amount of raw material, add again machining man-hour,
The most important thing is to there is no guarantee that the forging that design proposes should ensure that the technology of cross axle axial direction fibre is wanted as far as possible
Ask, cut off the tissue fibers of forging, make the mechanical property of product be substantially reduced, affect service life.
Summary of the invention
For solving technical problem described in background technology, the present invention by the following technical solutions: cross axle forging
Forging technique of full fiber, it comprises the following steps:
1) the first fire weight upsetting pull blank, uses upper and lower flat anvil to carry out vertical material jumping-up, and initial forging temperature controls
1200-1300 DEG C, final forging temperature controls at 700-900 DEG C；
2) the second pyrogene type, by saturating for blank forging, compacting, finishing blank from all directions, finally uses 90 ° of triangle pressures
Shoulder upper and lower surface press-in, overturns 90 ° and extrudes opposite groove, and initial forging temperature controls at 1100-1200 DEG C, eventually
Forging temperature controls at 600-800 DEG C；
3) the 3rd fire in-mold molding；Finally by blank four sections of roundlets of pulling to forging's block dimension, initial forging temperature control
System is at 1100-1300 DEG C, and final forging temperature controls at 600-900 DEG C；
4) put in storage through the conformance with standard regulation that examines the forged pieces.
Preferably, step 2) in mould need in advance by triangle pressure shoulder preheating 200-250 DEG C and smear lubrication
Agent, constantly to overturn blank in forging process.
The invention has the beneficial effects as follows: this technique is less demanding to workman's technology, easy and simple to handle, production efficiency is high；
The shape of loose tool forging is accurate, and dimensional accuracy is higher, thus more than technique, block is few, allowance is little；Owing to adopting
Use all fiber forging method, both saved a large amount of raw material, decrease again machining man-hour, complete streamline
Tissue fibers, makes the mechanical property of product be greatly improved, increases the service life.
