Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing:

[0019] An embodiment of a spline sleeve cold extrusion processing method: comprising the following steps,

[0020] 1) Blank blanking. Raise the saw blade, shake the handle of the sawing machine to feed the material, visually inspect the gap between the end face and the backing, confirm that the material is in place, and start the equipment to saw the material. Cutting by sawing machine, the inclination of the end face is less than 1°;

[0021] 2) Blank annealing. Put the material vertically into the material basket, use the hoisting car to lift the material basket and place it on the working platform, place three baskets of products on the working platform for each heat treatment, open the sand door to send the product into the furnace, and wait until the platform completely enters the furnace Inside, close the sand door, open the temperature regulator on the control box...

Abstract

The invention relates to a cold extruding processing method of a spline housing and the spline housing produced by the same. The cold extruding processing method of the spline housing comprises the following steps: blanking of a tubular blank, annealing of the blank, performing turning on an inner bore, saponification of phosphorus, hole shrinkage and extrusion, cold extrusion of the spline and turning and shaping. The wall thicknesses of the larger end, transmission section, and smaller end of the spline manufactured by the method are equal, wherein yield torsion of the spline housing is more than 30,000Nm. The invention has the beneficial effects: firstly, the application of two cold extruding molding processes ensures that the strengthen of the material are improved after the cold-workhardening, the whole part is designed in an equicohesive manner, and greatly improves the material utilization and reduces the process cost; secondly, the processing procedures are reduced, the processing cycle of the part is shorten, and the production efficiency is improved while the cost is lowered; and thirdly, the hot processing procedures such as forging and tempering with high-energy consumption and pollution are cancelled, thus achieving obvious effects of energy saving and emission reduction.

Description

technical field [0001] The invention relates to a spline sleeve used on a transmission shaft, in particular to a spline sleeve cold extrusion processing method and the spline sleeve produced therefrom. Background technique [0002] At present, the spline sleeve parts used on the transmission shaft of heavy commercial vehicles are generally designed by experience, and the parts are relatively bulky. The raw material is generally thick-walled seamless pipe, and the processing process includes pipe blanking, local heating forging and upsetting of the large-diameter A-end, quenching and tempering, inner hole turning, inner spline multiple broaching, and outer turning. The material utilization rate of this design and processing spline sleeve is only 40%, and there are forging, quenching and tempering heat treatment, multi-pass turning process and internal spline broaching process, which has more energy consumption and chips, and the processing cost and material cost are relativel...
