Description

Technical Field

[0001] This invention relates to the field of non-ferrous metal processing technology, specifically a drawing device for forming and processing internally threaded aluminum alloy tubes. Background Technology

[0002] Currently, the main production process for aluminum alloy internally threaded tubes in China is cold drawing. The main steps involve forming the extruded tube blank into a suitable semi-finished product size (internal thread tube blank) through multiple cold drawing processes. After softening its structure and eliminating cold working deformation stress through intermediate online annealing, it is then drawn at low speed to the finished tube with the outer diameter, wall thickness, and tooth height specified in the drawings using specialized internal thread forming equipment and matching internal thread forming dies.

[0032] Guide frames are fixedly installed on both upright plates 2, and auxiliary rollers 6 are rotatably connected to the end of the guide frame away from the upright plate 2.

[0033] In addition, an oil reservoir is fixedly connected to the first hydraulic pipe 16, a pressure valve is provided between the oil reservoir and the first hydraulic pipe 16, and an electric control valve is provided between the first hydraulic pipe 16 and the hydraulic cover 17.

[0034] In the implementation of this invention, the aluminum alloy tube is first drawn using the drawing die 5. Specifically, the drawing part 4 is connected to the aluminum alloy tube blank, and then the shift drive motor 8 is started to drive the shift conveying screw 9 to rotate, thereby moving the drawing seat 3. The drawing seat 3 drives the drawing part 4 to move, thus completing the drawing of the aluminum alloy tube.

[0035] After being pulled out, the aluminum alloy tube is cut using the cutting assembly 11. The translation drive motor 26 and the cutting motor are started to make the cutting saw blade 23 rotate and move, thus completing the cutting of the aluminum alloy tube.

[0036] The cut aluminum alloy tube falls downwards and, guided by the guide rod 10, falls into the placement groove 28 on the rotating column 27. Then, the rotary drive motor 31 is started, driving the rotating column 27 to rotate, causing the aluminum alloy tube to move to one side of the clamping plate 35. Next, the hydraulic rod 12 is shortened, and during the shortening process, the hydraulic rod 12 drives the push-pull block 13 to move, causing the push-pull rod 15 to press into the first hydraulic pipe 16, thereby causing the hydraulic oil in the hydraulic cover 17 and the second hydraulic pipe 18 to flow, pressing the hydraulic plate 36 and driving the first jacking rod 37 to move until the clamping plate 35 tightly presses the aluminum alloy tube into the placement groove 28. At the same time, the second jacking rod 38 drives the jacking head 39 to press against one end of the aluminum alloy tube. Simultaneously, the push-pull block 13 drives the tapping rod 34 to move, and the tapping motor 33 is started, driving the tapping rod 34 to rotate. As the tapping rod 34 moves, it performs tapping processing on the aluminum alloy tube.

[0037] After the tapping process is completed, the hydraulic rod 12 is reset and the tapping motor 33 is started to rotate in the opposite direction to realize the retraction of the tapping rod 34. Then, the rotary drive motor 31 is started to drive the rotating column 27 to rotate, so that the tapped aluminum alloy tube is discharged from the release port 30.

[0038] Before tapping, the first solenoid valve is closed. After the clamping plate 35 and the jacking head 39 clamp the aluminum alloy tube, the oil pressure in the first hydraulic pipe 16 increases, and the hydraulic oil enters the oil reservoir through the pressure valve for storage. When the tapping is completed and the hydraulic rod 12 is reset, the solenoid valve is closed first. When the push-pull rod 15 moves, it creates a negative pressure state in the first hydraulic pipe 16, which draws out the oil in the oil reservoir. When the tapping rod 34 is completely detached from the aluminum alloy tube, the solenoid valve is opened again, which reduces the hydraulic oil in the second hydraulic pipe 18 and the hydraulic cover 17, thus releasing the fixation of the aluminum alloy tube.
