The external spline cold extrusion forming die has the advantages of low construction cost, high production efficiency and material saving; compared with a cold extruder, the die is high in processing speed and low in product rejection rate and is suitable for large-scale product processing.
Description
Technical field
The utility model relates to external splines cold extrusion device technical field, is specifically related to external splines cold-extrusion shaping mould.
Background technology
External splines is multiple tooth part, and external splines is connected in intensity, technique and use following feature: connect stressed comparatively even; Can bear larger load; Guidance quality is good.External splines is applicable to that centering precision requirement is high, transmitting torque is large or the connection of frequent slippage.External splines is widely used in the mechanized equipments such as automobile, tractor, engineering machinery, in actual production, is in great demand.Because external splines is difficult to processing with conventional machine cut processing.At present, the comparatively advanced processing method of external splines is to adopt cold extrusion press processing, but cold extrusion press is too expensive, and production cost is high, and process velocity is slow, and material expends larger.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of cost expense is low, production efficiency is high and save the external splines processing mold of material, i.e. external splines cold-extrusion shaping mould.
Technical problem to be solved in the utility model realizes by the following technical solutions:
External splines cold-extrusion shaping mould, comprises upper bolster and die shoe, and described upper bolster is provided with guide pin bushing near end positions, upper bolster bottom is provided with punch, punch outside is provided with punch retainer, and punch top is provided with punch insert, between punch insert and upper bolster, is provided with upper padding plate; Described die shoe is provided with guide pillar near end positions, die shoe top is provided with die block, die shoe middle part is provided with push rod fixed cover a, push rod fixed cover a inside is provided with push rod, push rod fixed cover a top is provided with push rod fixed cover b, and push rod fixed cover b is in die block inside, and push rod fixed cover b top is provided with lower bolster, lower bolster top is provided with die, and die top is provided with die overcoat.Push rod can eject the waste material that machines rear generation.
Described punch retainer inside is provided with fixture of the spring.Fixture of the spring is used for clamping spline, is convenient to spline to process.
On described die, be processed with the key tooth of spline.
The beneficial effects of the utility model are: the utlity model has the advantage that cost expense is low, production efficiency is high and save material, mould is faster than cold extrusion press process velocity, and product rejection rate is low, are applicable to a large amount of processing of product.
