Description

TECHNICAL FIELD

[0002] A pipe joint with three openings is called a three-way pipe, and the three-way pipe is widely used in pipe networks for conveying liquid and gas. The three-way pipe can be divided into stainless steel three-way pipes, carbon steel three-way pipes, copper three-way pipes, PVC three-way pipes and cast iron three-way pipes according to materials. For manufacturing a three-way pipe by using a seamless pipe, two processes, i.e. hydraulic bulging and hot pressing, are usually adopted. The hydraulic bulging is a forming process for bulging out a branch pipe by axial compensation of metal materials. In the process, a special hydraulic machine is used to inject liquid into a pipe blank, and the pipe blank is extruded by synchronous centering movement of two horizontal side cylinders of the hydraulic machine, so that the volume of the pipe blank is reduced, and the liquid in the pipe blank is pressurized with the volume reduction of the pipe blank. When the required pressure for bulging out the branch pipe is reached, the metal materials flow along the inner cavity of the die under the double action of the side cylinder and the liquid pressure in the pipe blank to bulge out the branch pipe. The hydraulic bulging is suitable for copper, aluminum and titanium, etc. In the prior art, the length-adjusted pipe blank needs to be repeatedly placed into the die of the hydraulic machine by workers, which is not only troublesome in operation, but also reduces the manufacturing efficiency and has certain safety hazards.

Referring to the above, when in use, the drive motor 70601 is turned on, and the drive motor 70601 operates, with the output shaft rotating. This rotation drives the second rotating shaft 70402 to rotate together via the pulley assembly 70602. The small gear 70604 on the second rotating shaft 70402 rotates along with it, while the large gear 70603 rotates synchronously in the opposite direction due to meshing. The small gear 70604 on the first crossbar 70501 also rotates synchronously in the opposite direction due to meshing, driving the first crossbar 70501 to rotate together. Since the two small gears 70604 rotate in the same direction, the second rotating shaft 70402 and the first crossbar 70501 also rotate in the same direction. As the second rotating shaft 70402 and the first crossbar 70501 are the power sources for the operation of the drive component 705 and the drive unit 704, respectively, the drive component 705 and the drive unit 704 are driven to operate synchronously.

[0051] like Figures 12-15 As shown, in some embodiments, the fixing mechanism 8 includes a vacuum pump 801 and a fixing tube 802 both mounted on the movable frame 703. The vacuum pump 801 is fixed on the movable frame 703, and the fixing tube 802 is vertical and fixed on the movable frame 703. One end of the fixing tube 802 is connected to the input end of the vacuum pump 801, and the other end is connected to a suction cup 803. The suction cup 803 is horizontal and fixedly connected to the fixing tube 802. The shape of the suction cup 803 is as follows: Figure 12As shown, the suction cup 803 has a connecting hole 804 and multiple annularly arranged strip grooves 805. The connecting hole 804 is vertical, and the strip grooves 805 are horizontal. The fixing tube 802 communicates with the connecting hole 804. The suction cup 803 has air passages 806, the same number as the strip grooves 805, which correspond one-to-one. The air passages 806 are horizontal, and all air passages 806 communicate with the connecting hole 804. The strip grooves 805 have multiple spaced-apart through holes 807, all communicating with the air passages 806. The through holes 807 are vertical. The suction cup 803 has multiple spaced-apart arc-shaped grooves 808 forming a concentric circle structure. The arc-shaped grooves 808 are horizontal and communicate with the strip grooves 805. Referring to the above, during use, the suction cup 803 contacts the outer surface of the tube blank, and the vacuum pump 801 is turned on. The process involves extracting air from the fixing tube 802, connecting hole 804, strip groove 805, air channel 806, through hole 807, and arc groove 808, creating a negative pressure state within these components to fix the wafer blank. The multiple strip grooves 805, air channels 806, through holes 807, and arc grooves 808 enhance the adsorption strength of the wafer blank, thereby improving the stability of the fixation. In practical use, a sealing ring can be added to the bottom of the suction cup 803 to improve sealing. Conversely, when releasing the wafer blank, air is pumped into the fixing tube 802, connecting hole 804, strip groove 805, air channel 806, through hole 807, and arc groove 808 via vacuum pump 801 to release the silicon wafer from fixation.
