Correspondingly, two first extensions 24 and two second extensions 162 are also provided. Thus, the first elastic reset member is provided so that the top seat moves up and resets after the tube is processed, thereby realizing that the upper pressure die, lower pressure die and side pressure die release the tube, so as to facilitate the subsequent removal or movement of the tube to switch processing positions. At the same time, the installation hole is provided to facilitate the assembly and connection between the first elastic reset member and the top seat and the base.

A second elastic reset member 18 is provided between the support base 16 and the base 10. When the top seat moves down, the linkage part contacts the limiting step to move the support base down, so that the lower pressing die is close to the tube for stamping operation. After stamping is completed, the support base is reset upward under the action of the second elastic reset member. Preferably, the second elastic reset member is a spring, and several second elastic reset members are provided and arranged at intervals along the length direction of the lower end of the support base.

[0051] Furthermore, the movable seat 133 is connected to a third elastic reset member 19 for movable reset on the chamber. Preferably, the movable seat 133 has a third slider 137, and the chamber 14 is provided with a third sliding groove (not shown in the figure) extending to the left and right. The third slider is adapted to the third sliding groove, which is beneficial to the displacement stability of the movable seat on the chamber.

[0052] The key design feature of this utility model is that it mainly uses the design of each component to control the top seat to move down through the drive device, so that the two upper side dies and two lower side dies move toward the tube, thereby realizing the upper dies, lower dies and side dies to stamp the tube to form a flower tube structure, reducing equipment energy consumption. The structure is ingenious and reasonable, stable in use, low in cost and wide in application.

[0053] Secondly, the setting of the limiting step is to stop and limit the movement of the linkage part when it moves down, so as to ensure the effect of the upper die, lower die and side die on the tube stamping and forming.

[0054] Furthermore, the first elastic reset component is provided so that the top seat moves upward and resets after the tube is processed, thereby enabling the upper pressure die, lower pressure die, and side pressure die to loosen the tube, facilitating the subsequent removal or movement of the tube to switch processing positions.
