Description

Technical Field

[0001] This utility model relates to the field of tube shrinking processing technology, specifically a high-speed tube shrinking machine feeding device with adjustable feeding speed. Background Technology

[0002] A pipe shrinking machine is used to expand and shrink pipe ends under normal conditions. Pipe shrinking is a forming process that reduces the diameter of the pipe blank's end. The pipe blank enters the deformation zone under axial force, where it undergoes tangential shrinkage plastic deformation. It then enters the stabilization zone, ultimately forming a reduced end diameter. Pipe shrinking machines are widely used for processing and forming pipe joints, automotive oil pipes, air ducts, water pipes, air conditioning pipes, and other connection parts, making them ideal pipe end forming equipment. When expanding or shrinking pipes, the pipe needs to be transported to the placement table via a feeding device.

[0003] However, most existing pipes are stacked together, requiring manual intervention to place each pipe on the platform. Furthermore, some conveying devices cannot quickly adjust for different pipe specifications when conveying pipes. Therefore, they do not meet the current needs. To address this, we propose a high-speed pipe shrinking machine feeding device with adjustable feeding speed. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1.

By controlling the switch of the second motor, the second motor can drive the first threaded rod to rotate, and the two first threaded plates can move simultaneously in a direction closer or further apart, driving the horizontal plate and vertical plate to move, thereby adjusting the distance between the two limiting mechanisms. It is suitable for U-shaped tubes of different widths.

In addition, by setting up the roller, jamming during the conveying process can be prevented. This utility model can limit and convey U-shaped tubes of different widths, improving its applicability.

[0014] 2. This utility model, by comprising a support plate, a second electric push rod, a clamping mechanism, a third electric push rod, and a first arc-shaped plate, allows the U-shaped tube to be conveyed to the upper surface of the worktable. By controlling the second electric push rod, the support plate retracts into the inner side of the groove. Then, by controlling the second and third electric push rods, the first and second arc-shaped plates move upwards, bringing the U-shaped tube into contact with the upper surfaces of the first and second arc-shaped plates. Finally, by controlling the switch of the first electric push rod, the arc-shaped pressure plate moves towards the outer surface of the U-shaped tube, stabilizing the U-shaped tube and enabling subsequent tube shrinking and bending processes.

The roller 502 also prevents jamming during conveying. When the tube is conveyed to the upper surface of the worktable 1, the support plate 15 is retracted into the inner side of the groove 7 by controlling the second electric push rod 14. Then, by controlling the second electric push rod 14 and the third electric push rod 16, the first arc plate 1002 and the second arc plate 11 are moved upward, and the U-shaped tube is in contact with the upper surface of the first arc plate 1002 and the second arc plate 11.

This utility model can limit and convey U-shaped tubes of different widths, improve applicability, and can convey the U-shaped tube to the worktable 1 and clamp it for convenient subsequent processing.
