[0041] With reference to Figure 5 , the concave die block 7 is bolted on the moving die 2, the concave die block 7 is internally hollow and open at one end facing the convex die column 4, the concave die block 7 is slidingly sleeved on the clutch support 0, and the circumferential inner side wall of the concave die block 7 is tightly attached to the wave crest of the corrugated outer side wall of the clutch support 0.

[0042] With reference to Figure 3 and Figure 5 , the inner convex column 8 coaxial with the convex die column 4 is arranged in the concave die block 7, the inner convex column 8 vertically slides through the inner and outer side walls of the concave die block 7, the concave die block 7 is provided with the avoiding slot 13 for the sliding of the inner convex column 8, the diameter of the inner convex column 8 is smaller than the inner diameter of the convex ring 5, and the inner convex column 8 is used for pressing the clutch support 0 blank on the convex ring 5.

[0043] With reference to Figure 3 , Figure 4 and Figure 5The movable die 2 is provided with a pre-pressing part 9 for pre-pressing the clutch support 0 blank on the male die column 4. The pre-pressing part 9 comprises a pre-pressing cylinder 91 provided on the movable die 2 and electrically connected to the control system. The piston rod of the pre-pressing cylinder 91 slides through the inner male column 8. A pressing block 92 is bolted on the piston rod of the pre-pressing cylinder 91. The pressing block 92 is used to press the clutch support 0 blank on the male die column 4.

[0044] With reference to Figure 3 The movable die 2 is provided with a pre-pressing part 9 for pre-pressing the clutch support 0 blank on the male die column 4. The pre-pressing part 9 comprises a pre-pressing cylinder 91 provided on the movable die 2 and electrically connected to the control system. The piston rod of the pre-pressing cylinder 91 slides through the inner male column 8. A pressing block 92 is bolted on the piston rod of the pre-pressing cylinder 91. The pressing block 92 is used to press the clutch support 0 blank on the male die column 4.

[0045] The control system starts the pre-pressing cylinder 91. The piston rod of the pre-pressing cylinder 91 drives the pressing block 92 to press the clutch support 0 blank on the male die column 4. At this time, the inner top wall of the clutch support 0 blank abuts against the convex ring 5. Moreover, the circumferential outer side wall of the male die column 4 is in close contact with the circumferential inner side wall of the clutch support 0 blank. In this process, the open end of the clutch support 0 blank drives the stripper block 62 to descend. The floating ring plate 61 causes the gas spring 64 to be continuously compressed.

[0046] In the process of combining the movable die 2 with the static die 1, the control system starts the pre-pressing cylinder 91. The piston rod of the pre-pressing cylinder 91 is continuously contracted until the inner male column 8 abuts against the clutch support 0 blank. With the movable die 2 continuing to approach the static die 1, the inner male column 8 punches out the step crease 03 of the closed end of the clutch support 0 blank under the action of the convex ring 5.

[0047] In this process, the circumferential inner side wall of the female die block 7 always limits the deformation of the corrugated outer side wall of the clutch support 0 to the outside. Moreover, the male die column 4 limits the deformation of the corrugated inner side wall of the clutch support 0 to the inside. In this way, the machining process of the step crease 03 of the clutch support 0 is completed.

[0048] In the process of separating the movable die 2 from the static die 1, the gas spring 64 restores the deformation. The piston rod of the gas spring 64 drives the floating ring plate 61 to rise. The floating ring plate 61 drives the open end of the clutch support 0 to synchronously rise through the stripper block 62. In this way, the separation of the clutch support 0 from the male die column 4 is realized. The clutch support 0 separated from the male die column 4 is clamped on the inner side wall of the female die block 7 through the friction force.

[0049] At this time, the control system starts the stripping cylinder 101, and the piston rod of the stripping cylinder 101 extends, and the piston rod of the stripping cylinder 101 drives the inner protruding column 8 to descend through the mounting plate 102, and the descending inner protruding column 8 drives the clutch support 0 to descend, until the clutch support 0 is separated from the concave die block 7, so as to complete the machining process of the clutch support 0.

[0050] The implementation principle of the embodiment 1 is that the worker puts the clutch support 0 blank on the protruding die column 4, at this time, the corrugated outer edge of the clutch support 0 blank is located between the positioning column 14 and the protruding die column 4, and the circumferential outer side wall of the protruding die column 4 is in close contact with the circumferential inner side wall of the clutch support 0, and the clutch support 0 blank blocks the signal transmission between the signal transmitter 11 and the signal receiver 12, and the control system obtains the signal feedback that the clutch support 0 blank has been placed.

[0051] The control system starts the pre-pressing cylinder 91, and the piston rod of the pre-pressing cylinder 91 drives the pressing block 92 to press the clutch support 0 blank on the protruding die column 4, at this time, the inner top wall of the clutch support 0 blank abuts on the convex ring 5, and the circumferential outer side wall of the protruding die column 4 is in close contact with the circumferential inner side wall of the clutch support 0 blank, in this process, the open end of the clutch support 0 blank drives the stripping block 62 to descend, and the stripping block 62 makes the gas spring 64 be continuously compressed through the floating ring plate 61.

[0052] In the process that the moving die 2 is combined with the stationary die 1, the control system starts the pre-pressing cylinder 91, and the piston rod of the pre-pressing cylinder 91 is continuously contracted, until the inner protruding column 8 abuts on the clutch support 0 blank, and with the moving die 2 continuing to approach the stationary die 1, the inner protruding column 8 punches out the step crease 03 of the closed end of the clutch support 0 blank under the action of the convex ring 5.

[0053] In this process, the circumferential inner side wall of the concave die block 7 always limits the corrugated outer side wall of the clutch support 0 to deform outward, and the protruding die column 4 limits the corrugated inner side wall of the clutch support 0 to deform inward, so as to complete the machining process of the step crease 03 of the clutch support 0.

[0054] In the process that the moving die 2 is separated from the stationary die 1, the gas spring 64 restores the deformation, the piston rod of the gas spring 64 drives the floating ring plate 61 to ascend, the floating ring plate 61 drives the open end of the clutch support 0 to ascend synchronously through the stripping block 62, so as to realize the separation of the clutch support 0 from the protruding die column 4, and the clutch support 0 separated from the protruding die column 4 is clamped on the inner side wall of the concave die block 7 through the friction force.

[0055] At this time, the control system starts the stripper cylinder 101, the piston rod of the stripper cylinder 101 extends out, the piston rod of the stripper cylinder 101 drives the inner protruding column 8 to descend through the mounting plate 102, the descending inner protruding column 8 drives the clutch support 0 to descend, until the clutch support 0 is separated from the die block 7, so as to complete the processing process of the clutch support 0.

[0063] At this time, as the clutch bracket 0 continues to slide, the friction between the clutch bracket 0 and the first column module 43 and the clutch bracket 0 and the second column module 44 will drive the second column module 44 to slide in the direction close to the movable die 2, and under the limiting action of the anti-slip rail 48, the second column module 44 slides along the inclined contact surface between the second column module 44 and the connecting ring seat 42, and the distance between the two adjacent second column modules 44 becomes smaller.

[0067] At this time, as the clutch support 0 continues to slide, the friction between the clutch support 0 and the first column module 43 and the clutch support 0 and the second column module 44 will drive the second column module 44 to slide towards the movable mold 2, and under the limiting action of the anti-slip rail 48, the second column module 44 slides along the inclined contact surface between the connecting ring seat 42, and the distance between the two adjacent second column modules 44 becomes smaller.

[0068] The second column module 44 separates from the inner side wall of the clutch support 0, and at the same time, the second column module 44 drives the connecting ring seat 42 to move towards the movable mold 2, and in the process of vertical sliding of the connecting ring seat 42, at the same time, under the combined limiting action of the connecting groove 47 and the connecting slide rail 46, the first column module 43 slides along the length direction of the chassis slide strip 45 on the connecting ring seat 42 towards the axis of the bottom chassis 41, and the distance between the two adjacent first column modules 43 becomes smaller.

[0069] Until the first column module 43 separates from the inner side wall of the clutch support 0, so that the clutch support 0 quickly realizes the effect of demolding, and when the clutch support 0 completely separates from the first column module 43 and the second column module 44, the connecting ring seat 42, the first column module 43 and the second column module 44 will reset under the action of gravity.
