[0036] Specifically, the punch power assembly 3 can move relative to the limit track 15 by moving the slider 17, thereby changing the positions of the flanging die 18 and the flaring chamfering die 19, and realizing the switching of the flanging die 18 and the flaring chamfering die 19. When the flanging die 18 moves to the pipe processing object 14, the flanging process is performed, and when the flaring chamfering die 19 moves to the pipe processing object 14, the flaring chamfering process is performed. The design of the anti-rotation punch adapter 16 can improve the processing accuracy of the flanging die 18 and the flaring chamfering die 19.

[0037] In a possible embodiment, the part forming assembly 2 also includes a support rod 20 and a rod driving member 21; the support rod 20 is located between the upper die seat 5 and the lower die seat 6, one end of the support rod 20 corresponds to the pipe processing object 14, and the other end of the support rod 20 is connected to the rod driving member 21. A pendulum block support 22 is connected to one side of the lower die seat 6 close to the punch power assembly 3, and the pendulum block support 22 is connected to a pendulum block body 24 through a pendulum block shaft 23; the end of the pendulum block shaft 23 is connected to a rotary cylinder body 25, and the rotary cylinder body 25 is connected to the side of the lower die seat 6 through a rotary cylinder seat 26; a notch is provided on the side of the lower die seat 6, and a wedge block 27 is provided inside the notch, and the wedge block 27 and the rotary cylinder seat 26 are fixedly connected; the center of the pit pressing slider 11 is filled with a slider spring 28, and the slider spring 28 presses the pit pressing slider 11 against the wedge block 27 in the mold opening state. Side; a guide groove 29 is formed between the upper flanging block 7 and the lower flanging block 8, and the swing block body 24 swings upward relative to the swing block axis 23 to the guide groove 29 to compress and align the end of the pipeline processing object 14; the interior of the upper mold base 5 is filled with a preload spring 30, and the lower end of the preload spring 30 contacts the upper surface of the upper flanging cavity insert 9; the side of the upper mold base 5 is connected to a sensing rod 31, and the side of the lower mold base 6 is connected to a proximity switch 32; the sensing rod 31 and the proximity switch 32 are used to sense the opening and closing actions of the upper mold base 5 and the lower mold base 6.

[0038] Specifically, the upper flange cavity insert 9 is slidably matched with the upper die seat 5 (H7 / F6); the pre-stressing spring 30 adopts SSWL14-30 to have an ejection pre-stressing effect on the upper flange cavity insert 9, and the gap is opened by 5mm; the pit pressing slider 11 is reset under the action of the slider spring 28, and the pit pressing slider 11 is required to slide with the matching part of the lower die seat 6 (H7 / f6)), and be close to the wedge block 27, and the stroke of the pit pressing slider 11 is 5mm; in the open mold state, the support rod 20 is retracted under the action of the rod driving part 21, and the pendulum block body 24 is in the lower position, which is convenient for the semi-finished parts to be placed in the cavity.

[0039] During the processing, the machine tool clamping power assembly 4 is started, and at the same time the rod driving part 21 moves forward, the support rod 20 is inserted into the semi-finished part, and the speed regulating valve of the rotary cylinder body 25 is adjusted to make the speed of the rotary cylinder body 25 slower than the cylinder pneumatic speed of the rod driving part 21. After the support rod 20 is inserted, the rotary cylinder body 25 drives the pendulum block body 24 to guide and press the semi-finished part again, but it must be completed before the upper flange cavity insert 9 presses the part.

[0040] When the distance between the upper die seat 5 and the lower die seat 6 is 10.7mm, the shovel base 10 contacts the pit pressing slider 11. The upper die seat 5 continues to move downward, and the pit pressing slider 11 starts to move toward the part. When the mold closing distance is 5mm, the upper flanging cavity insert 9 contacts the lower flanging cavity insert 33. At this time, the corrugation of the semi-finished part is guaranteed to be within the cavity range. At this time, the pit pressing slider 11 is 2.33mm away from the corrugation. When the upper flanging cavity insert 9 is pressed against the flanging cavity insert, the pit pressing is completed. At the same time, the sensing rod 31 interacts with the proximity switch 32 to generate an electrical signal, and the rotary cylinder body 25 rotates the rocker body back to the initial position. It should be noted that the machine tool time relay should be adjusted, and the punch power assembly 3 starts to move after a delay of 2 seconds to prevent the rocker body 24 from interfering with the expansion and chamfering mold 19.

[0041] When the swing block body 24 returns to the initial position, the machine tool control system commands the forming cylinder to move forward, and the flaring and chamfering mold 19 contacts the part for flaring and chamfering. After the chamfering is completed, the forming cylinder returns. After the control stops, the mold change cylinder moves longitudinally to change the mold, so that the flanging mold 18 is aligned with the central axis of the molding cavity, and stops moving. The forming cylinder moves forward, and the flanging mold 18 contacts the part for flanging molding. The flanging mold 18 presses the part and then returns. After the forming cylinder stops, the machine tool opens the part molding assembly 2. The upper die seat 5 will reach the dead point and the machine tool stops moving, and all systems return to the initial state.

[0042] In a possible embodiment, in order to ensure the dent size of the corrugated part and the product appearance requirements, the wedge angle of the dent slider 11 needs to be reasonably designed, and the optimal wedge angle is 25° to ensure that the dent slider 11 starts to contact the part and dent after the upper flange cavity insert 9 contacts the lower flange cavity insert 33. On the one hand, if the wedge angle is too large, the dent slider 11 will dent first, and there will be no limit on the left and right sides, and the part material will flow out, causing the upper flange mold cavity insert to cut (clamp) the part to produce indentations or iron filings, causing appearance problems for the product; on the other hand, if the wedge angle is too small, the dent slider 11 will have a small running distance, the dent slider 11 will not be in place, and the dent size will be unqualified.

[0043] In a possible embodiment, the clamping power assembly 4 of the machine tool is responsible for the clamping action of the mold of the part; the die power assembly 3 is responsible for the expansion, chamfering and flanging action of the part; the pneumatic triplet (oil mist, pressure reducing valve and filter), the single electric control solenoid valve is responsible for the action of the rod driving part 21 pulling the support rod 20; four speed regulating valves are used to adjust the movement speed of the rod driving part 21 and the rotary cylinder body 25; the double electric control solenoid valve is used to swing the swing block body 24. The part forming assembly 2 is responsible for the pitting and flanging forming of the part. First, the pneumatic triplet and the solenoid valve control assembly are installed on the machine tool, and then the electrical signal of the solenoid valve is connected in parallel to the double-handed start signal source. The return stroke of the swing block body 24 is completed by controlling the double electric control solenoid valve through the proximity switch 32. The rotation angle of the rotary cylinder body 25 is adjusted by adjusting the screw: the adjusting screw adjusts the stroke of the rack cylinder, the rack drives the gear to rotate, and the speed regulating valve controls the movement of the rotary cylinder body 25 and the rod driving part 21 through the flow.

After the support rod 20 is inserted, the rotary cylinder body 25 drives the pendulum block body 24 to guide and press the semi-finished part again, but it must be completed before the upper flange cavity insert 9 presses the part.
