[0001] The utility model relates to the technical field of shaft tube processing, and particularly relates to a shaft tube extrusion forming device. Background Technique

[0002] When processing a shaft tube, first, a high-quality seamless steel tube is cut into sections by a cutting machine, and both ends of the steel tube are subjected to a primary high-temperature heating process. After extrusion, the main part of the steel tube is thickened. Secondly, the heated and thickened steel tube is subjected to a three-stage extrusion process to ensure the forming of the shaft tube.

The first driving block 11 and the side corresponding to the second driving block 12 are both inclined, and the inclined portion of the first driving block 11 and the inclined portion of the second driving block 12 have complementary inclination angles.

[0024] Through the setting of the clamping assembly, when it is necessary to perform extrusion forming processing on both ends of the shaft tube, the shaft tube can be placed in the inner cavity of the arc groove 4, and then the two-way hydraulic cylinder 10 can be opened through the external controller. The upper telescopic end of the two-way hydraulic cylinder 10 will drive the upper first driving block 11 to extrude the corresponding second driving block 12, and drive the two groups of clamping seats 9 to move toward the direction of the shaft tube through the second driving block 12, so as to extrude and fix the shaft tube in the arc groove 4.

Then the user can control the telescopic end of the double-acting hydraulic cylinder 10 to move downward, so that the clamping seats 9 clamping both sides of the shaft tube are loosened. At this time, the shaft tube will automatically fall downward under the action of its own gravity, achieving the purpose of automatic blanking. After blanking is completed, the user can place the next group of shaft tubes to be processed in the arc-shaped groove 4 above and clamp and fix them through the clamping component.
