The large automotive market also has a great demand for transmission clutches. The clutch of the gearbox comprises a clutch gear hub, a friction plate, a steel sheet and the like, and the torque is connected and disconnected by pressing and loosening the friction plate. The clutch hub is one of the core parts in the clutch, and the clutch hub and the friction plate are usually engaged with each other by a tooth profile. The clutch hubs are typically provided with inner longitudinal teeth, outer longitudinal teeth, or both. The tooth profile of the clutch hub is generally formed by two methods of cutting machining or forging extrusion.
The cutting process is performed by hobbing, broaching and the like, so that the processing efficiency and the material utilization rate are low, the material fiber streamline is cut off, the fatigue impact resistance is weak, and the processing of the non-through teeth cannot be realized. The requirement of the forging and extrusion molding on the tonnage of equipment is high, the blank is usually required to be heated, and the energy consumption is high. In addition, the extrusion strength born by the forging extrusion forming die is high, and the service life is short.
In the past, I have adopted the forging machine processing mode to process the forging stock to the cup dish form, and then have processed the gear hobbing machine with the external tooth position gear hobbing, gear shaper or planer internal tooth position processing, not only production is slow, and required process is held up long when mass production, and processing equipment and board operating personnel are numerous, and area is big and once only invest in many.

Detailed Description
To facilitate an understanding of the present invention by those skilled in the art, specific embodiments thereof are described below with reference to the accompanying drawings.
As shown in fig. 1 to 8, the invention provides a process for preparing an internal spline and an external spline of a clutch hub of an automatic transmission, which comprises the following steps: firstly, placing a plate material on a leveling machine by an external mechanical arm, leveling the plate material by the leveling machine, and ensuring that the plane difference of the whole plate material is less than 0.2mm so as to ensure the wall thickness consistency of a clutch gear hub; secondly, placing the plate processed by the leveling machine into a positioning punching die by an external mechanical arm, and punching the plate into a round plate blank as shown in figure 1; thirdly, moving the round plate blank into a stretching die by an external mechanical arm, drawing the round plate blank by the stretching die, and stamping the round plate blank into a cup shape as shown in figure 2; fourthly, an external mechanical arm moves the cup-shaped blank into the inner and outer gear hub molds, and the cup-shaped blank is stamped by the inner and outer gear hub molds to preliminarily form the inner and outer gear hubs as shown in fig. 3; fifthly, after the fourth step, primarily molding the inner and outer gear hubs, but the sizes of the inner and outer gear hubs are not accurate enough, and then moving the inner and outer gear hubs into a molding die by an external mechanical arm to finish the shaping work of the inner and outer gear hubs; sixthly, side punching the side length of the gear hub, basically molding the shaped inner and outer gear hubs, punching the heights of the inner and outer gear hubs at the time, and putting the shaped inner and outer gear hubs into a side-punching gear hub side length mold by an external mechanical arm to complete the side length cutting work of the gear hub, as shown in fig. 4; seventhly, laterally punching the first oil passing holes 1, as shown in figure 5; eighthly, laterally punching the second oil passing holes 2, as shown in fig. 6; traditional first oil passing hole 1 and second oil passing hole 2 are all supported by lathe cutting, burrs are more, the finish turning process is needed, the process is complex, the first oil passing hole 1 and the second oil passing hole 2 are machined by punching, burrs are small, the machining speed is high, deformation of the whole inner and outer gear hubs during punching is avoided, interval punching is adopted, punching is performed twice through a seventh step and an eighth step, but the punching process of twice is not divided, and only a tooth groove is required to be ensured to be arranged between the adjacent oil passing holes during punching. Ninthly, laterally punching the first fastening ring clamping grooves 3, as shown in fig. 7; tenth step, side punching second tighrening ring draw-in groove 4, as shown in fig. 8, the punching process of first tighrening ring draw-in groove 3 and second tighrening ring draw-in groove 4 is not in order, if punch to first tighrening ring draw-in groove 3 and second tighrening ring draw-in groove 4 simultaneously, then whole inside and outside tooth hub is out of shape when the punching press very easily, can cause the product to scrap when serious, consequently, the punching process of tighrening ring draw-in groove also is the interval punching press.
In the present embodiment, a tooth groove is formed between the first oil passing hole 1 processed in the seventh step and the next first oil passing hole 1, and a tooth groove is formed between the second oil passing hole 2 processed in the eighth step and the next second oil passing hole 2. Spline is separated between the first fastening ring clamping groove 3 processed in the ninth step and the next first fastening ring clamping groove 3, and spline is separated between the second fastening ring clamping groove 4 processed in the tenth step and the next second fastening ring clamping groove 4. On the one hand, the interval punching is to ensure that when the first oil passing hole 1 or the first fastening ring clamping groove 3 is punched, the inner and outer gear hubs are punched relatively dispersedly, so that the inner and outer gear hubs cannot crack due to more integral stress points during punching. On the other hand, the density of the punch is also considered, and if the density of the punch is higher, the pressure born by the punch of the die is also higher, so that the requirement on the die is increased, and the investment of enterprises is increased.
Meanwhile, in order to facilitate the turnover of parts in each step, a mechanical clamping jaw is arranged between every two adjacent steps, manpower is replaced by the mechanical clamping jaw, the automatic turnover of workpieces is realized, and the production efficiency of products is improved.
The invention achieves the following beneficial effects:
according to the invention, the first oil passing hole 1 and the second oil passing hole 2 are punched at intervals, so that the influence on the appearance of the clutch gear hub during punching is avoided, and the roundness of the clutch gear hub is ensured; the first fastening ring clamping grooves 3 and the second fastening ring clamping grooves 4 are punched at intervals, so that the phenomenon that the quality of the clutch gear hub is influenced due to the deformation of the clutch gear hub when the first fastening ring clamping grooves 3 and the second fastening ring clamping grooves 4 are punched is avoided; the original cutting machining or forging extrusion is replaced by a stamping mode in the whole clutch gear hub machining process, so that the machining procedures of the clutch gear hub are reduced, and the preparation efficiency of the clutch gear hub is improved; the turnover process of whole equipment is all transferred through external arm, has saved the manpower.
The above-described embodiments of the present invention do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
