Abstract

A kind of Correction Die of slip shaft yoke, correction for slip shaft yoke, the slip shaft yoke includes splined shaft and the U-shaped plug set on splined shaft one end, including correction upper module and correction lower module, it corrects and is equipped with standard type chamber compatible with slip shaft yoke external surface shape on the lower end surface and the upper surface of correction lower module of upper module, the standard type chamber includes spline spindle-type chamber and U-shaped plug type chamber, the correction upper module and the standard type chamber corrected on lower module enclose the correction type chamber matched with slip shaft yoke, correct the jaw that clamping slip shaft yoke forging is equipped in the middle part of the standard type chamber of lower module, the correction upper module and correction lower module are connected and fixed by right angle lock catch.The utility model can guarantee slip shaft yoke quality, avoid U-shaped plug curvature overproof, improve qualification rate.

Description

A kind of Correction Die of slip shaft yoke

Technical field

The utility model belongs to mould for forging correction field, and in particular to a kind of Correction Die of slip shaft yoke.

Background technique

Currently, traditional horizontal forging and upsetting machine edge mould belongs to combined type, including upper and lower die body and upper and lower body of punch, punch holder, Blocking punch-pin and blocking cavity plate, finish-forging punch-pin and finish-forging cavity plate, when processing die body up and down, using round bar overall processing, It is subsequent that using wire cutting, at two symmetrical semi-cylindricals, but up and down, for die body when carrying out linear cutter, there are biggish Deviation, the die body up and down after actual processing be it is asymmetric, the forging that will cause production later easily bends, offsets and wrong The problems such as mould, rejection rate can be machined by increasing；Promotion with customer to quality requirement, the reduction of patch are curved to yoke Curvature requirement is stringenter, is Meet Customer Requirements, and yoke production is designed with correcting process.

Utility model content

In order to overcome the drawbacks of the prior art, the utility model provides a kind of Correction Die of slip shaft yoke.

Based on above-mentioned purpose, the present invention is adopted the following technical scheme that:

A kind of Correction Die of slip shaft yoke, for the correction of slip shaft yoke, the slip shaft yoke includes splined shaft and sets U-shaped plug in splined shaft one end, including correction upper module and correction lower module correct lower end surface and the correction lower die of upper module Standard type chamber compatible with slip shaft yoke external surface shape is equipped on the upper surface of block, the standard type chamber includes splined shaft Type chamber and U-shaped plug type chamber, the correction upper module and the standard type chamber corrected on lower module enclose and slip shaft yoke matching The correction type chamber of conjunction corrects the jaw that clamping slip shaft yoke forging is equipped in the middle part of the standard type chamber of lower module, the correction upper mold Block and correction lower module are connected and fixed by right angle lock catch.

Further, the middle part of the correction upper module standard type chamber two sides is equipped with right angle convex block, corrects lower module standard The middle part of type chamber two sides is accordingly equipped with right angle groove compatible with right angle convex block, the side of the right angle convex block and horizontal plane Angle be 90 °.

Further, the fit clearance of the right angle convex block and right angle groove is 0.3mm.

Further, the rib of the right angle convex block is arc transition.

The jaw is located at spline spindle-type chamber close to one end of U-shaped plug type chamber.

The advantages of the utility model: (1) Correction Die of the utility model produces on 4000T press machine, slip shaft yoke Forging is put into correction drag chamber by worker after cutting side, and correction upper mold is fallen, and is molded, is achieved the purpose that bending with sizing degree, Guarantee that curvature in acceptability limit；

2) it uses right angle lock catch fit clearance for 0.3mm, avoids generating mismatch phenomenon, since right angle lock catch is vertical 90 °, Lateral force will not be generated, the power of vertical direction can be only generated, reduce mold lateral force, avoid lock or crack of die.

3) the utility model ensure that the curvature of slip shaft yoke, improve product qualification rate, while also improving customer Satisfaction, and the phenomenon that avoid lock or crack of die.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the top view of mold under the utility model.

Specific embodiment

The structure of the utility model is described in further details with reference to the accompanying drawing.

As illustrated in fig. 1 and 2, a kind of Correction Die of slip shaft yoke, for the correction of slip shaft yoke, the slip shaft yoke packet Splined shaft and the U-shaped plug set on splined shaft one end, including correction upper module 1 and correction lower module 2 are included, correction upper module 1 It is equipped with standard type chamber 3 compatible with slip shaft yoke external surface shape on lower end surface and the upper surface of correction lower module 2, it is described Standard type chamber 3 includes spline spindle-type chamber 31 and U-shaped plug type chamber 32, the standard on the correction upper module 1 and correction lower module 2 Type chamber 3 encloses the correction type chamber matched with slip shaft yoke, corrects and is equipped with clamping splined shaft in the middle part of the standard type chamber of lower module 2 The jaw 4 of forging is pitched, the correction upper module 1 and correction lower module 2 are connected and fixed by right angle lock catch.

Further, the middle part of correction 1 standard type chamber of upper module, 3 two sides is equipped with right angle convex block 11, corrects lower module 2 The middle part of 3 two sides of standard type chamber be accordingly equipped with the compatible right angle groove 21 of right angle convex block 11, the right angle convex block 11 The angle of side and horizontal plane is 90 °.

Further, the fit clearance of the right angle convex block 11 and right angle groove 21 is 0.3mm.

Further, the rib of the right angle convex block 11 is arc transition.

The jaw 4 is located at spline spindle-type chamber 31 close to one end of U-shaped plug type chamber 32.

In use, the slip shaft yoke forging of heat is put into the standard type for correcting lower module 2 by worker after slip shaft yoke cuts side In chamber 3, correction upper module 1 is fallen, and is molded, and is achieved the purpose that correct slip shaft yoke U-shaped plug curvature, is bent U-shaped plug Degree guarantees in acceptability limit.
