Abstract
The utility model relates to a spline half axle forged blank for a heavy truck. The spline half axle forged blank comprises a half axle blank body and a shaft rod, wherein the end of the half axle blank body is connected with the shaft rod; a spline is arranged on the shaft rod; a lubricating layer is arranged on the surface of the shaft rod; and the diameter of the shaft rod is 0.05 to 0.5 mm more than that of a tooth top of the spline. The spline half axle forged blank has the beneficial effects that: when a product is processed, high efficiency is realized, and materials are saved; compared with the conventional cutting process, the spline half axle forged blank has the advantages that: the spline is formed by adopting cold extrusion, the production efficiency and the material utilization rate are improved remarkably, the production cost is relatively low, and energy consumption of a single product, auxiliary material consumption and the die cost are lower than those of the cutting process; due to the formed spline part, the intensity is relatively high; the spline subjected to cold extrusion forming has a complete metal streamline, so that the intensity of the spline is improved; and the surface quality of the spline is improved, so that detection and assembly are facilitated.
Description
Technical field
The utility model relates to the Metal Forming technical field, relates in particular to a kind of heavy motor vehicle semiaxis splined forging stock.
Background technology
The semiaxis that has spline is the important Transmission on the heavy motor vehicle, and its diameter is bigger.At present; This parts general-duty work flow is: one of which; Adopt cutting working method, promptly Milling Process directly mills out spline at the semiaxis blank; This spline is owing to adopt milling mode processing, and metal streamline is cut off and makes that spline intensity reduces, the life-span reduces and efficient is low, waste raw MAT'L, cause the technology cost high; Simultaneously, be prone to produce milling mark during the milling spline, this position is prone to cause stress concentration and reduces fatigue life after the heat treatment, and the spline straightness accuracy of milling descends, and also causes service life not high; Its two, because of adopting rolling processing, this technology can only be processed modulus 2 with interior castellated shaft, and this technology equipment needed thereby is expensive, cutter is made difficulty, cost is high.Therefore, to above aspect, need reasonably improve prior art.
The utility model content
To above defective; The utility model provides a kind of can improve Formation of Axle Shaft Spline intensity, increase the service life, strengthen functional reliability, tooling cost is low, production efficiency is higher, the heavy motor vehicle semiaxis splined forging stock of the assembling that is content with very little, to solve many deficiencies of prior art.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of heavy motor vehicle semiaxis splined forging stock comprises semiaxis blank body and axostylus axostyle, and said semiaxis blank end of body connects axostylus axostyle, and this axostylus axostyle is provided with the spline of cold-extrusion shaping, and said axostylus axostyle surface is provided with lubricating layer; Said shaft diameter is greater than spline tooth top diameter 0.05mm-0.5mm.
Compared with prior art, the beneficial effect of the described heavy motor vehicle semiaxis of the utility model splined forging stock is:
(1) product is adding man-hour, efficient and economical with materials: compare with traditional cutting, through adopting the cold-extrusion shaping spline, its production efficiency and stock utilization significantly improve;
(2) productive costs is lower: the energy consumption of single products, and machine supplementary product onsumption and die cost are lower than cutting;
(3) preferable through the spline position intensity that shaping is set: the cold-extrusion shaping spline, have complete metal streamline, improved the intensity of spline;
(4) preferable through the spline position roughness that shaping is set, splined surfaces is smooth, straightness accuracy is good, be beneficial to the crossing ability that detects and assemble.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of the said heavy motor vehicle semiaxis of the utility model embodiment splined forging stock.
Among the figure:
1, semiaxis blank body; 2, axostylus axostyle; 3, flange; 4, spline.
The specific embodiment
As shown in Figure 1; The described heavy motor vehicle semiaxis of the utility model embodiment splined forging stock; Comprise semiaxis blank body 1 and axostylus axostyle 2, said semiaxis blank body 1 end connects axostylus axostyle 2, and this axostylus axostyle 2 is provided with spline 4 and axostylus axostyle 2 diameters greater than spline 4 diameter 0.05mm-0.5mm; Said axostylus axostyle 2 surfaces are provided with the lubricating layer that the phosphatization saponification is handled, this semiaxis blank body 1 other end mounting flange 3.Adding man-hour; Axostylus axostyle 2 upwards places the mould of the following form frame system on the special hydraulic press; Closed form frame system down; Start special hydraulic press and drive the spline shaping dies downfeed motion that is fixed on the top mold frame, accomplish the precise cold extrusion molding of spline 4, obtain heavy motor vehicle semiaxis splined forging stock; Then, start the special hydraulic press drive and be fixed on the spline shaping dies upward movement on the top mold frame, form frame system is opened down in spline 4 demouldings, takes out heavy motor vehicle semiaxis splined forging stock.
Above embodiment is the more preferably specific embodiment a kind of of the utility model, and common variation that those skilled in the art carry out in present technique scheme scope and replacement should be included in the protection domain of the utility model.
