Description
Technical field
The utility model is related to a kind of mould structure of machine components processing, and in particular to a kind of traditional yoke shaping punching press
Mould.
Background technology
Traditional yoke is used to transmit the moment of torsion of engine and bears to bend combined load, is to be applied to automobile, container ship
Etc. the heavy connection in transmission system, market demand is very big.The structure proximate Y shape of traditional yoke, one end is a post
Shape output shaft, the other end, which is width size between U-shaped prong, the fork of prong, the fork ear depth, fork is long differs, and fork ear wall thickness compares
It is relatively thin.The manufacture of current propeller shaft yoke typically all uses casting, and fork ear and output shaft are by being welded to connect, such processing
Mode is not only complicated cumbersome, low production efficiency, and often has weld defect, and easy fracture produces quality accidents, and product is qualified
Rate is low.
Utility model content
In view of this, the utility model provides a kind of traditional yoke shaping diel, and yoke manufacture is integrally formed, product
Qualification rate is high, and production efficiency is high.
To solve above technical problem, the technical solution of the utility model provides a kind of traditional yoke shaping stamping die
Tool, it includes upper die and lower die setting up and down, and upper mould connects and output shaft die cavity and fork ear die cavity are set in drift, lower mould, defeated
Shaft die cavity and fork ear die cavity connect insertion with central shaft, and the diameter of fork ear die cavity is more than the diameter of output shaft die cavity, pitches ear type
The accent end face of chamber is concordant with the upper surface of lower mould, is fixed with securing cover plate, securing cover plate and opens up on the accent for pitching ear die cavity
Limited location hole, the center line of spacing hole is overlapped with the center line of drift, 1.1~1.3 times of a diameter of punch diameter of spacing hole,
It is provided with drift on cooling-water duct, drift and offers several cooling water spouts, cooling water spout is connected with cooling-water duct.
Further, the upper die and lower die are respectively sleeved in die sleeve, are fixed or are connected with transmission mechanism by die sleeve.
Further, the spacing hole is arranged on the center of securing cover plate.
Further, limited block is connected with the spacing hole, limited block is equidistantly positioned on the circumference of spacing hole, just
Further limited in the up and down motion position to drift, it is to avoid the unnecessary displacement of drift, cause fork ear shaping failure.
Further, the drift upper end is provided with oblique angle portion, and oblique angle portion can avoid workpiece from producing burr in shaping,
So that substantially increasing the production efficiency of workpiece without deburring after Workpiece shaping.
The utility model by bar preparatory processing into ladder shaft-like bar, in the die cavity for then putting it into lower mould, by
Be less than the diameter of fork ear die cavity in the diameter of output shaft die cavity, therefore position-limiting action served to bar, back punching head in transmission
Moved down in the presence of mechanism and the securing cover plate pair that impact is formed on fork ear, fork ear die cavity is carried out to the bar in fork ear die cavity
The movement of drift serves positioning action while being also convenient for the separation of the fork ear after shaping and drift, and the cooling set on drift
Water spout is cooled down to shaping workpiece, improves product quality.
Therefore the utility model has made the yoke of conventional cast welding fabrication into integrated punching shaping, it is to avoid output shaft
Weld defect with pitching ear, mould structure is simple, convenient for production, substantially increases the qualification rate and production efficiency of product.
