[0021] The present invention will be further described below with reference to the embodiments.

[0022] Example 1, as Figures 1 to 5 As shown, this utility model is an automatic stamping and forming device, including a worktable 1, a column 10, a top plate, and a lower pressure plate 7 that can slide on the column 10. The top plate is provided with a lifting cylinder 12 that drives the lower pressure plate 7 to move up and down. The bottom of the lower pressure plate 7 is equipped with a sliding plate 8 that can move left and right. A forming extrusion head is fixed at the bottom of the sliding plate 8. The worktable 1 below the forming extrusion head is provided with a clamping and rotating mechanism that clamps the workpiece and drives it to rotate. A pressure cone wheel 4 is provided on one side above the clamping and rotating mechanism. The pressure cone wheel 4 is connected to a lifting and translating mechanism that drives it to move up and down and slide horizontally. An extrusion disc 13 is provided on the opposite side of the pressure cone wheel 4. The extrusion disc 13 is connected to a translation adjustment mechanism. The sliding plate 8 is connected to a horizontal moving mechanism that drives it to slide left and right.

[0023] During operation, the pipe fitting to be flanged is placed on the clamping and rotating mechanism, clamped, and rotated. Then, the lifting cylinder 12 extends, allowing the forming extrusion head to reach the center of the pipe fitting, with the lower part of the forming extrusion head at the extrusion height. Then, the horizontal moving mechanism drives the sliding plate 8 to move outward, bringing the forming extrusion head close to the upper inner wall of the pipe fitting for extrusion and expansion. At the same time, the translation adjustment mechanism drives the extrusion disc 13 close to the upper outer wall of the pipe fitting for outer extrusion support. The forming extrusion head and the extrusion disc 13 work together to make the upper part of the pipe fitting smoothly flanged outward at a certain angle. Then, the horizontal moving mechanism and the lifting cylinder 12 work together to drive the forming extrusion head back to its original position, and the translation adjustment mechanism drives the extrusion disc 13 back to its original position. Then, the lifting and translation mechanism drives the edge pressing cone wheel 4 to move the top of the outer wall of the pipe fitting, performing roller pressing and flanging on the expanded pipe fitting. Then, the lifting and translation mechanism drives the edge pressing cone wheel 4 back to its original position, the clamping and rotating mechanism stops rotating, and the pipe fitting is released.

[0024] In Example 2, based on Example 1, the forming extrusion head includes a forming extrusion shaft 5, and a connecting shaft 6 is fixed to the top of the forming extrusion shaft 5. The top of the connecting shaft 6 is fixed to the sliding plate 8.

[0025] The horizontal movement mechanism includes a horizontal slide rail fixed to the bottom of the lower pressure plate 7, a horizontal slider on the horizontal slide rail, a sliding plate 8 fixed to the horizontal slider, and a horizontal movement cylinder 9 fixed to the bottom of the lower pressure plate 7. The piston rod end of the horizontal movement cylinder 9 is fixed to the sliding plate 8. During operation, the horizontal movement cylinder 9 extends, which drives the sliding plate 8 to slide horizontally along the horizontal slide rail, thereby adjusting the horizontal position of the forming extrusion head.

[0026] The translation adjustment mechanism includes a translation slide plate 19, a translation slider fixed to the bottom of the translation slide plate 19, a translation rail connected to the translation slider, and the translation rail fixed to the worktable 1. A translation cylinder 20 is fixed to the worktable 1, and the piston rod end of the translation cylinder 20 is fixed to the translation slide plate 19. A support frame 18 is fixed to the top of the translation slide plate 19, and an adjusting screw 11 is threaded onto the support frame 18. The extrusion disc 13 is rotatably mounted on the adjusting screw 11. In use, the translation cylinder 20 extends, driving the translation slide plate 19 to move along the translation rail, thereby adjusting the extrusion disc 13 to approach the outer wall of the pipe for extrusion support. Furthermore, before operation, the adjusting screw 11 can be rotated as needed to adjust the vertical position of the extrusion disc 13.

[0027] The lifting and translating mechanism includes a lifting frame 16, an installation shaft is fixed to the inner end of the lifting frame 16, a pressure cone wheel 4 is rotatably mounted on the installation shaft, a lifting slide plate 14 is fixed to the outer end of the lifting frame 16, a lifting slide plate 14 is connected to a lifting slide rail, a lifting drive mechanism is connected to the lifting slide rail, a lifting bracket 15 is fixedly connected to the lifting slide rail, a horizontal slide plate 17 is fixed to the bottom of the lifting bracket 15, and a horizontal slide plate 17 is connected to a horizontal slide rail and a horizontal drive mechanism.

[0028] The lifting drive mechanism includes a lifting screw rotatably mounted on the lifting bracket 15, a lifting nut connected to the lifting screw, the lifting nut being fixed to the lifting slide plate 14, and a lifting motor fixed to the upper end of the lifting screw.

[0029] The horizontal drive mechanism includes a horizontal lead screw connected to a horizontal nut, which is fixed to a horizontal slide plate 17. A horizontal slider that mates with a horizontal slide rail is fixed to the bottom of the horizontal slide plate 17. A base is fixed to the bottom of the horizontal slide rail and is fixed to the worktable 1. The horizontal lead screw is rotatably mounted on the base, and a horizontal drive motor is fixedly connected to the outer end of the horizontal lead screw. When the pressing cone wheel 4 moves, the horizontal drive motor rotates, driving the horizontal lead screw to rotate, thereby driving the horizontal slide plate 17 to move horizontally through the horizontal nut. Simultaneously, the lifting motor rotates, driving the lifting lead screw to rotate, thereby driving the lifting slide plate 14 to rise and fall through the lifting nut, thus realizing the horizontal movement and vertical lifting of the pressing cone wheel 4.

[0030] The clamping and rotating mechanism includes an outer shaft 21 rotatably mounted on a worktable 1. An inner clamping shaft 22, which can be raised and lowered, is connected to the outer shaft 21 via a spline. An outer support sleeve 2 is fixed to the top of the outer shaft 21. An inner clamping sleeve 3, which is fixed to the inner clamping shaft 22, is provided inside the outer support sleeve 2. The outer wall of the inner clamping sleeve 3 is tapered. Multiple clamping opening slots are evenly provided on the outer side wall of the inner clamping sleeve 3.

The rotary drive mechanism includes a driven pulley fixed to the bottom of the outer shaft 21. The driven pulley is connected to a driving pulley via a belt, and the driving pulley is connected to a rotary motor. The outer shaft 21 is mounted on the worktable 1 via a bearing sleeve. During operation, the pipe is placed inside the inner clamping sleeve 3, where it is supported and positioned at the bottom. Then, the clamping cylinder retracts, causing the inner clamping shaft 22 to descend, thereby moving the inner clamping sleeve 3 downward and retracting it into the outer support sleeve 2. During the retraction process, the outer support sleeve 2 squeezes the inner clamping sleeve 3, causing the upper part of the inner clamping sleeve 3 to deform and clamp the pipe. Then, the rotary motor rotates, driving the outer shaft 21 to rotate via the driving pulley, belt, and driven pulley. This rotation, in turn, drives the inner clamping shaft 22 and the inner clamping sleeve 3 to rotate together, clamping the workpiece.

This narrative style is merely for clarity.
