A stamping hole 61 is opened at the top of the stamping table 6, the diameter of which is adapted to the outer diameter of the interface portion 12 of the pipe interface. The stamping head 8 is coaxially arranged with the stamping hole 61. The stamping head 8 includes a mounting base 85 fixedly connected to the telescopic end of the telescopic cylinder 21, and an expanding column 83 is fixedly mounted at the bottom of the mounting base 85. The outer diameter of the expanding column 83 is adapted to the inner diameter of the interface portion 12 of the pipe interface, and a truncated cone 84 is provided at the bottom of the expanding column 83.

[0032] Preferably, the mounting base 85 comprises a circular plate 81 and a circular truncated cone 82, the top surface of the circular plate 81 is fixed to the telescopic end of the telescopic cylinder 21, the large-diameter surface of the circular truncated cone 82 is fixed to the bottom surface of the circular plate 81, the small-diameter surface of the circular truncated cone 82 is fixed to the expanding column 83, and the outer diameter of the expanding column 83 is the same as the diameter of the small-diameter surface of the circular truncated cone 82.

[0033] The sliding plate 9 is coaxially arranged on the telescopic rod of the telescopic cylinder 21, and the sliding plate 9 and the telescopic rod are in sliding connection. The sliding plate 9 is in sliding connection with the stand column 4 and slides up and down along the stand column 4. The top plate 3 is provided with a driving mechanism 22 for driving the sliding plate 9 to slide. The bottom of the sliding plate 9 is fixedly provided with a pressing ring 7, which is coaxially arranged with the punching hole 61. The inner diameter of the pressing ring 7 is greater than the outer diameter of the punching head 8 and less than the outer diameter of the punching table 6.

[0034] The driving mechanism 22 comprises a nut 221 and a first screw rod 223. The nut 221 is embedded and fixed on the top plate 3. The first screw rod 223 extends vertically and is in threaded connection with the nut 221.

The upper end of the second screw rod 23 is fixedly provided with a positioning column 24, which is coaxially arranged with the punching hole 61. The lower end of the second screw rod 23 is fixedly provided with a handle.

[0036] The machining tool of the embodiment is used for machining the reinforcing type pipe joint of the embodiment on the tank bottom plate 1. The pipe joint is integrally machined, so it is necessary to separately punch the tank bottom plate 1 before the tank is formed.

[0037] Before punching, a person first needs to open a circular tank opening part 11 on the discharging position of the tank bottom plate 1. The hole diameter of the circular tank opening part 11 is matched with the outer diameter of the positioning column 24, so that the taper 84 at the bottom of the expanding column 83 can be inserted into the circular tank opening part 11 for expanding.

[0038] As shown in Figure 5 When punching, first rotate the second screw rod 23, so that the positioning column 24 at the top of the second screw rod 23 moves upward. Stop moving when the upper end surface of the positioning column 24 is higher than the upper end surface of the punching table 6. At this time, place the opened tank bottom plate 1 on the punching table 6, and make the circular tank opening part 11 on the tank bottom plate 2 coaxially arranged on the positioning column 24, so as to complete the positioning.

[0039] Then the first screw rod 223 is rotated, the first screw rod 223 of the two driving mechanisms 22 is synchronously rotated, thereby synchronously driving the sliding plate 9 to slide downwards, and further making the pressing ring 7 press and be arranged on the tank body bottom plate 1 to be fixed. After the tank body bottom plate 1 is fixed, the second screw rod 23 is rotated, thereby making the positioning column 24 move downwards and reset.

The conical frustum 84 of the stamping head 8 is firstly inserted into the circular tank mouth part 11, and the inclined surface of the conical frustum 81 uniformly expands the circular tank mouth part 11 outwards. With the continuous pressing of the stamping head 8, finally the circular tank mouth part 11 is expanded to be consistent with the outer diameter of the diameter expansion column 83, thereby forming the annular interface 12. The stamping head 8 continues to press downwards, and stops when the circular frustum 82 is arranged on the top surface of the tank body bottom plate 1, at this time the inclined surface of the circular frustum 82 stamps the transition surface between the upper end of the interface part 12 and the tank body bottom plate 1 into an inclined surface.

[0041] After the stamping is completed, the first screw rod 223 is rotated to reset the pressing ring 7, the telescopic cylinder 21 is retracted, and the tank body bottom plate 1 can be taken off, and the reinforced pipe interface is integrally stamped and formed on the tank body bottom plate 1.
