Technical field
The utility model belongs to vehicle transmission forging shaft production technical field, is specifically related to a kind of New-type transmission shaft slip yoke forging hot-cutting die.
Background technology
When conventionally carrying out the design of slip yoke hot-cutting die, same heat expansion coefficient of discharge can be multiplied by slip yoke cold forging ' s block dimension entirety, and according to this hot size design hot-cutting die.But in actual production, because the complicated shape coefficient of slip yoke forging is higher, the cooling velocity of each several part is also inconsistent, causes the shrinkage degree of each several part in cooling procedure different.As shown in Figure 1, existing slip yoke hot-cutting die comprises die ontology 1, slip yoke forging placed cavity is provided with in die ontology 1, slip yoke forging placed cavity comprises fork ear chamber 2 and chamber, bar portion 3, distance A between outer side edges edge, two fork ends, ear chamber 2 is 86mm, distance B between two fork tip inside edges, ear chamber 2 is 57.9mm, the external diameter C in chamber, bar portion 3 is 39.4mm, the distance D that end, chamber 3, bar portion is in axial direction arrived between the fork earhole center of pitching ear chamber 2 is 137.9mm, the fork distance E of ear chamber 2 between the outer edge step place, both sides closing on chamber 3, bar portion place is 52.6mm, fork earhole center is 31mm with the axial distance F on fork center edge edge, ear chamber 2.
Can not well match with actual forging ' s block dimension according to the edger designed by above-mentioned size, each several part trimming discontinuity, and then produce following problem:
1, partial cut burr is comparatively large, and the operation forging that must increase by one sanding thorn just can conform to quality requirements, and adds process cost, manpower, waste of time.
2, in trimming process, each several part discontinuity causes producing following problem: 1., cause forging flexural deformation, directly causes forging to be scrapped, reduce product quality and production efficiency time serious; 2., to equipment cause and injure in various degree, increase the working strength of service worker, have impact on manufacturing schedule to a great extent.
3, the cutting edge each several part degree of wear of trim die is uneven, mould is scrapped seriously and in advance because of concentrated wear, reduces die life, add product cost.
4, in metalworking process, location is not accurate, and centre bore easily bores partially, product quality is reduced and even produces waste product.
Utility model content
The utility model, in order to solve weak point of the prior art, provides a kind of and guarantees that trimming operation uniform force, surface spikes are few, the New-type transmission shaft slip yoke forging hot-cutting die of metalworking accurate positioning, long service life.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: New-type transmission shaft slip yoke forging hot-cutting die, comprise die ontology, slip yoke forging placed cavity is provided with in die ontology, slip yoke forging placed cavity comprises fork ear chamber and chamber, bar portion, it is 0.3mm that described die ontology is provided with thickness H on center edge edge, fork ear chamber, width is the process area of 15mm, distance A between outer side edges edge, two fork ends, ear chamber is 86mm, distance B between two fork tip inside edges, ear chamber is 57mm, the external diameter C in chamber, bar portion is 39.6mm, the distance D that bar portion in axial direction arrives end, chamber between the fork earhole center of pitching ear chamber is 138.1mm, the fork distance E of ear chamber 2 between the outer edge step place, both sides closing on chamber place of bar portion is 52.8mm, fork earhole center is 31mm with the axial distance F on fork center edge edge, ear chamber.
Adopt technique scheme, by carrying out a large amount of tracking, measurement, statistics and analysis to each several part size of slip yoke forging, respective scaling is summed up to different parts, and is repeatedly revised by actual production, finally draw more satisfactory ratio value.Meanwhile, the drill centers technique of conveniently follow-up metalworking, a process area is added in the center, fork ear chamber of edger, solves centre bore in metalworking process and easily bore an inclined difficult problem.
Prove through test of many times, use the utility model to have following beneficial effect:
1. forging surface residual burr evenly and burr remnants≤0.5mm, and the product of 80% eliminates sanding thorn operation, reduces process cost.
2. the trimming bending deformation quantity≤0.4mm of forging, forging quality uniformity improves, and percent defective reduces by 1%; The maintenance and repair number of times of equipment reduces 1-2 time.
3. be improved the service life of edger, decrease the number of times of more mold exchange in forging process, improve production efficiency, reduce die manufacturing cost.
4. the percent defective caused because holing in metalworking process declines 0.5%.
