[0037] Reference Figure 2 The forming seat 3 is provided with a forming groove 31, the shape of which corresponds to the pressure head 23. When the pressing plate 22 falls, the pressure head 23 can fall into the forming groove 31. The opening direction of the forming groove 31 is parallel to the length direction of the telescopic member 233. After the pressure head 23 slides to different positions on the pressing plate 22, it can still fall into the forming groove 31.

The fixing presses 33 are pressed on the forming seat 3, so that the forming seat 3 maintains a stable position on the workbench 1. Positioning pieces 34 are provided on both sides of the forming seat 3, and the positioning pieces 34 are configured as bolts. The bolts are horizontally arranged and connected to the workbench 1, and the ends of the bolts abut against the end faces of the forming seat 3.

[0040] Reference Figure 4 and Figure 5, a feed trough 111 is provided on the two side panels 11, and the feed trough 111 passes through the side panels 11. The user can insert a steel pipe of a longer length into the feed trough 111 and place it in the placement slot 32. A positioning mechanism 4 is provided on the workbench 1, and the positioning mechanism 4 is installed on the outside of the side panel 11. The positioning mechanism 4 includes a mounting frame 41, a guide rod 42, a limit plate 43, a scale 44 and a screw 45. The mounting frame 41 is fixed on the workbench 1, the guide rod 42 is horizontally arranged and fixed on the mounting frame 41, the guide rod 42 passes through the limit plate 43, so that the limit plate 43 can slide along the length direction of the guide rod 42, and the screw 45 is rotatably connected to the mounting frame 41, and the screw 45 passes through the limit plate 43 and is threadedly connected to the limit plate 43.

By rotating the screw 45, the user can move the limit plate 43 to different positions on the guide rod 42 and keep it fixed. After the user inserts the steel pipe into the feed trough 111, by making the end of the steel pipe abut against the limit plate 43, the position on the steel pipe that needs to be folded can be located below the pressure head 23, thereby improving the efficiency of steel pipe processing. The scale 44 is set on one side of the limit plate 43, and the length direction of the scale 44 is parallel to the length direction of the guide rod 42. The user can adjust the position of the limit plate 43 according to the scale 44, thereby facilitating the user to use the positioning mechanism 4 to position the steel pipes with different processing requirements.

[0041] The implementation principle of the embodiment of the present application is as follows: by arranging the side plates 11 and the top plate 12 on the workbench 1, the hydraulic cylinder 21 can be installed above the workbench 1 and drive the pressing plate 22 and the pressing head 23 to move vertically back and forth. The user places the steel pipe on the forming seat 3, moves the pressing head 23 downward and falls into the forming groove 31, so that the pressing head 23 can crush the steel pipe. By opening a placement groove 32 on the forming seat 3, the steel pipe is clamped in the placement groove 32 for processing, thereby reducing the probability of the steel pipe slipping on the forming seat 3 when the pressing head 23 presses down the steel pipe, thereby improving the processing quality.
