[0027] like Figure 2 , Figure 4 As shown, a prismatic ring 401 is fixedly connected to the top outer wall of the stamping cylinder 4. A blocking groove 403, corresponding to and engaging with the prismatic ring 401, is provided at the top of the receiving groove 402. The top of the receiving plate 301 is fixedly attached to the extrusion plate 3. A groove is provided at the center of the bottom end of the stamping cylinder 4, with the top of the groove inclined in a conical shape towards the center.

The outer wall of the top bolt 302 is slidably connected to the stamping cylinder 4. The blocking groove 403 can... The prism ring 401 is engaged with the prism ring 401, thereby preventing the prism ring 401 from rotating. This restricts the rotation of the stamping cylinder 4, preventing it from disengaging from the top bolt 302. The receiving plate 301 is moved to the bottom, causing the blocking groove 403 inside the receiving plate 301 to disengage from the prism ring 401. This allows the stamping cylinder 4 to be easily removed from the receiving groove 402. The stamping cylinder 4 is then rotated to disengage from the top bolt 302, thus enabling the replacement and adjustment of the stamping cylinder 4.

Since the lead screw 101 is threadedly connected with the extrusion plate 3, the extrusion plate 3 is sleeved with the rotating column 1, and the lead screw 101 can drive the extrusion plate 3 to move to the bottom end, thereby driving the containing plate 301 to move to the bottom, and the punch cylinder 4 moves to the bottom and approaches the extrusion column 5 for extrusion, so that the corresponding petroleum perforating shell blank is extruded and formed, the working operation is realized, and different sizes of the punch cylinder 4 and the extrusion column 5 can be arranged in the containing plate 301 and on the top of the support plate 2 during use, so that the size of the perforating shell processed can be adjusted according to the interval size of the punch cylinder 4 and the extrusion column 5, and different sizes of the perforating shell can be processed on the two sides of the top of the support plate 2 as needed without disassembling and replacing the device, so that different processing requirements can be met.

[0031] When the size of the existing processing perforating shell needs to be adjusted, the movable plate 201 can be conveniently moved to the top, thereby driving the extrusion spring 502 to move to the top, releasing the extrusion of the extrusion spring 502 on the fixed ring 501, and then the extrusion column 5 can be conveniently rotated, thereby making the extrusion column 5 and the mounting bolt 503 separate from each other, so that the extrusion column 5 of different sizes can be conveniently replaced, and the fixed connection between the extrusion plate 301 and the containing plate 3 can also be released during use, thereby moving the containing plate 301 to the bottom, making the blocking groove 403 inside the containing plate 301 release the clamping of the prismatic ring 401, and then the punch cylinder 4 can be conveniently taken out from the inside of the containing groove 402, and the punch cylinder 4 is rotated to release the connection with the top bolt 302, thereby realizing the replacement and adjustment of the punch cylinder 4, so that the interval size between the punch cylinder 4 and the extrusion column 5 is adjusted, and then the size of the perforating shell inside the punch cylinder 4 changes during punching, and the size adjustment can be completed without disassembling the whole equipment, and the operation is very convenient.
