Embodiment 1

[0031] like figure 1 As shown, the processing technology of the spherical cage bell shell includes the following steps:

[0032] First, select the material: select the metal rod-shaped material, cut the required length of the rod blank, the diameter of the selected rod material and the length of the cut rod blank can be selected according to the size of the bell-shaped shell to be processed. , the intercepted bar blank such as figure 2 As shown in the first picture,

[0033]Secondly, carry out pretreatment: deburring the cut bar blank, so that the bar blank can be placed on the die of the cold extrusion machine more stably, so as to ensure the yield of workpiece processing. After the above treatment is completed, the two ends of the bar blank are chamfered, and the obtained bar blank is as follows: figure 2 As shown in the 2nd picture.

[0034] Annealing treatment: put the bar blank into the annealing furnace and gradually raise the temperature to 500°C for 2h; then keep...

Embodiment 2

[0043] The processing technology of the spherical cage and bell shell of this embodiment is basically the same as that of the first embodiment, and the difference lies in: annealing treatment: put the bar blank into the annealing furnace, and gradually increase the temperature to 600 ° C, and the duration is 1 h ; Then keep at this temperature for 0.3h, then gradually raise the temperature to 600°C within 1h, keep at this temperature for 0.3h, and then gradually raise the temperature to 700°C within 1h. Then, the temperature was gradually lowered to 660 °C for 1 h; then the temperature was gradually lowered to 300 °C by natural cooling to 400 °C, and the furnace was released, and the process lasted for 0.8 h.

[0044] Heat treatment: first clean the bell-shaped shell blank after cold extrusion, then quench the bell-shaped shell blank at a high temperature of 750 ° C for 0.5h, and then quickly cool to room temperature, the cooling rate is 200 ° C / s, again The cleaned bell she...

Embodiment 3

[0047] The processing technology of the spherical cage bell shell of this embodiment is basically the same as that of the first embodiment, and the difference lies in: annealing treatment: put the bar material into the annealing furnace, and gradually increase the temperature to 550 ° C, and the duration is 1.5 h; then keep at this temperature for 0.4h, then gradually increase the temperature to 625°C within 1.1h, keep it at this temperature for 0.4h, and then gradually increase the temperature to 750°C within 1.5h. Then, the temperature was gradually lowered to 680°C for 1.5h; then the temperature was gradually lowered to 275°C by natural cooling to 450°C, and the process lasted for 0.8h.

[0048] Heat treatment: first clean the bell-shaped shell blank after cold extrusion, then quench the bell-shaped shell blank at a high temperature of 800 ° C for 0.75h, and then quickly cool to room temperature, the cooling rate is 250 ° C / s, again The cleaned bell-shaped shell blank was...

A bell-like shell product manufactured by the process for machining the ball cage bell-like shell is stable in quality, high in production efficiency, short in production period, low in production cost and good in economy.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a processing technology of a spherical cage bell-shaped shell. Background technique [0002] The ball cage, also known as the constant velocity joint, is an important part of the car's transmission system. Its function is to transmit the power of the engine from the transmission to the two front wheels to drive the car at high speed. There are many types of constant velocity joints used in cars, among which the ball cage type constant velocity joint and the tripod type constant velocity joint are the most widely used, which mainly include sliding sleeves, three-way shafts, transmission shafts, star It is composed of main parts such as sleeve, cage and bell shell. Because the constant velocity universal joint transmits heavy driving torque, bears heavy load, high transmission precision, large demand, and is a safety part, its main parts are all made of precision forgi...
