It should be noted that: when the molded part rises to the limit position along with the T-shaped clamping sleeve 914 on the transmission mechanism 9, the boss on the top of the molded part will press against the bottom of the washer 709, so that the washer 709 is pressed to carry the movable block 708 up.

[0054] An inclined groove 712 is provided at the lower portion of the movable block 708 , and a T-shaped detection head 713 is movably connected inside the inclined groove 712 , and one end of the T-shaped detection head 713 extends to the outside of the detection disk 706 .

It should be noted that: the inner ring 715 is symmetrically fixed with a synchronization block, and synchronization grooves are provided on both sides of the gear rod 5. The two synchronization blocks are slidably connected to the inside of the two synchronization grooves. When the punch 11 moves the adjusting cylinder 702 upward, with the cooperation of the synchronization groove and the synchronization block, the gear rod 5 will not move with it to avoid interference; under the action of the semicircular groove 714, the adjusting cylinder 702 rotates forward through the slot 717 and the plug block 716 to rotate with the gear rod 5.

[0057] In this embodiment, Figures 1 to 15 As shown, the top surface of the arc wedge block 704 is set as an inclined surface, and the two arc wedge blocks 704 are arranged in a ring shape on the outer wall of the adjustment tube 702. It should be noted that when the adjustment tube 702 with the two arc wedge blocks 704 rises to the limit position, the two arc wedge blocks 704 cooperate with the two ball head pressure rods 705 to enable the adjustment tube 702 to rotate 180 degrees.

[0058] In this embodiment, Figures 1 to 15 As shown, the transmission mechanism 9 includes a transmission shaft 901, the top of the gear rod 5 is fixedly connected to the transmission shaft 901, the lower part of the transmission shaft 901 is fixedly sleeved with a waist-shaped groove plate 902, the inner bottom surface of the transmission sleeve 4 is slidably connected with a transmission rack 903, the top of the transmission rack 903 is movably connected to the inside of the waist-shaped groove plate 902, the side wall of the transmission rack 903 is meshed with the side wall of the upper part of the gear rod 5, the inner wall of the transmission sleeve 4 is fixedly connected with an electric telescopic plate 904 matched with the transmission rack 903, the right side of the inside of the transmission sleeve 4 is movably inserted with a push rod 905 matched with the block 15, the right side of the push rod 905 is movably connected with a return spring 906, and the left end of the push rod 905 is on the same line as the transmission rack 903. It should be noted that: when the gear rod 5 rotates 180 degrees, the electric telescopic plate 904 is automatically inserted into the left end position of the transmission rack 903, which can block the reset movement of the transmission rack 903. At this time, the push rod 905 will not push the transmission rack 903 to reset and move after being compressed. After the molded part at the bottom of the transmission sleeve 4 is unloaded, the electric telescopic plate 904 is started to reset and shrink, and the blocking of the transmission rack 903 is released; because the gear rod 5 can rotate 180 degrees, the inner circle of the molded part boss is in a flat state at this time, indicating that the molded part is a qualified product, and therefore the push rod 905 cannot press the transmission rack 903 to reset and move.

At this time, under the action of the main one-way bearing 907, the connecting plate 908 will not rotate with it. When the top rod 905 presses the transmission rack 903 to reset and move, the transmission shaft 901 will rotate synchronously with the connecting plate 908 during the reverse process.

[0060] The lower part of the hydraulic cylinder 8 is movably sleeved with a connecting rod 911, the bottom of the hydraulic cylinder 8 is fixedly connected with a pad 912, and a return coil spring 913 is fixedly connected between the bottom of the connecting rod 911 and the bottom of the pad 912.

[0069] In this embodiment, Figures 1 to 15 As shown, a punch hole is provided at the bottom of the female die 6 to match the adjusting cylinder 702, and the punch hole is coaxially arranged with the forming punch 12. It should be noted that the punch hole cooperates with the forming punch 12 to punch and form a boss structure of the formed part.

[0070] In this embodiment, Figures 1 to 15 As shown, spring holes are symmetrically opened at the bottom of the punch 11, and the upper parts of the two spring slide bars 10 are respectively slidably connected inside the two spring holes.

[0071] The use method and advantages of the present invention: The working process of the gas preheater stamping equipment is as follows:

[0072] like Figures 1 to 15As shown, when using the gas preheater stamping equipment, the steel plate is first accurately placed on the top of the punch 11 by the manipulator, and then the two hydraulic cylinders 8 are started to move the die downward for stamping. The steel plate is stamped into a concave ridge shape under the cooperation of the punch 11 and the die 6. At the same time, as the die 6 continues to move downward, the spring slide bar 10 is compressed. At this time, the punch 11 continues to move downward, so that the forming punch 12 on the top of the support seat 1 enters the inside of the die 6 to perform secondary stamping on the stamped steel plate, so that a ring boss is formed in the middle of the formed part;

[0073] When the stamping is completed, the two hydraulic cylinders 8 shrink and move upward, the spring slide bar 10 also resets and pushes the formed part up with the punch 11. During the upward movement of the hydraulic cylinder 8, the connecting sleeve rod 911 and the T-type clamping sleeve 914 will rise synchronously. At this time, the circular gear 919 on the slave shaft 918 of the T-type clamping sleeve 914 meshes with the side wall of the toothed plate 13 on the top of the support seat 1, so that the slave shaft 918 rotates with the slave H-type gear 921 through the slave one-way bearing 920, and then the slave H-type gear 921 rotates with the main H The H-shaped gear 917 meshes and rotates, so that the clamping block 922 on the slave H-shaped gear 921 and the main H-shaped gear 917 clamps the molded part on the top of the punch 11 as it turns over. The clamped molded part rises synchronously with the contraction of the hydraulic cylinder 8, and when the main H-shaped gear 917 rotates to the limit, the cone head limiting rod 925 inserted into the side wall of the T-shaped clamping sleeve 914 is movably inserted into the inside of the limiting hole 924 under the action of the limiting spring 926, so as to limit the clamping state of the main H-shaped gear 917;

[0074] As the die 6 rises with the hydraulic cylinder 8, the detection disk 706 at the bottom of the gear rod 5 gradually emerges from the bottom of the die 6, and as the T-clamping sleeve 914 rises, the boss on the molded part will pass through the detection disk 706 and press against the bottom of the gasket 709, so that the gasket 709 rises with the movable block 708 inside the detection disk 706. At this time, during the sliding cooperation between the inclined groove 712 and the T-type detection head 713, the T-type detection head 713 moves out from the inside of the detection disk 706 and overlaps the inner circle position of the boss of the molded part. When the adjusting cylinder 702 at the top of the die 6 moves up synchronously, the two arc wedge blocks 704 on the outer wall of the adjusting cylinder 702 rise and contact with the corresponding ball head pressure rod 705, so that the arc wedge block 704 rotates the adjusting cylinder 702 forward 180 degrees at the top of the die 6. During the rotation process of the adjusting cylinder 702 In the process, the semicircular groove 714 and the slot 717 inside the adjusting cylinder 702 cooperate with the ring 715 and the plug block 716 to rotate synchronously. At this time, the gear rod 5 at the inner ring position of the ring 715 rotates, so that the detection disk 706 at the bottom of the gear rod 5 rotates 180 degrees along the inner ring of the molded part boss with the two T-shaped detection heads 713. When there is a raised unevenness at the inner ring position of the molded part boss, the T-shaped detection head 713 is blocked and no longer rotates. At this time, the detection disk 706 and the gear rod 5 no longer rotate, so that the plug block 716 on the ring 715 is released from the slot 717, and the adjusting cylinder 702 that continues to rotate will not rotate with the ring 715 and the gear rod 5, and the upper part of the gear rod 5 will mesh with the transmission rack 903 during the positive rotation process in the transmission sleeve 4, so that the transmission rack 903 moves to the right;

[0075] After the hydraulic cylinder 8 rises to the limit, the electric telescopic cylinder 3 is started to move the transmission sleeve 4 to the right. At this time, the push rod 905 on the right side of the transmission sleeve 4 moves and contacts the block 15 on the right side of the support plate 2. When the gear rod 5 has not rotated 180 degrees, the left end of the transmission rack 903 is not in a locked state, so that the block 15 can press the push rod 905 to move. When the push rod 905 is pressed and pressed against the end of the transmission rack 903, the transmission rack 903 is reset and moved. During the reset movement of the transmission rack 903, it will pass through the waist-shaped groove plate 902 The transmission shaft 901 rotates, so that the transmission shaft 901 and the main one-way bearing 907 cooperate with the connecting plate 908. At this time, the two L-shaped push plates 910 at both ends of the connecting plate 908 slide inside the corresponding arc groove 909, and the L-shaped push plates 910 push the corresponding T-shaped clamping sleeve 914 and the connecting sleeve rod 911 to rotate on the surface of the hydraulic cylinder 8. At this time, the clamped molded parts also rotate. The rotated molded parts cannot accurately fall into the recycling box 16 during the unloading process. At this time, it can be judged that the boss of the stamped parts after molding does not meet the requirements;

[0076] When the detection plate 706 can stably rotate 180 degrees with the gear rod 5, the boss of the molded part meets the requirements, and after the gear rod 5 rotates 180 degrees, the transmission rack 903 moves to the right to the limit position. At this time, the electric telescopic plate 904 extends to limit the reset of the transmission rack 903, so that during the movement of the transmission sleeve 4 to the right, the top rod 905 presses the stopper 15 and does not reset the transmission gear inside the transmission sleeve 4. At this time, the extrusion spring of the side wall of the baffle 15 is compressed;

[0077] Finally, after the transmission sleeve 4 moves to the right to the extreme position with the die 6, the U-shaped unlocking block 17 is started to insert into the conical surface position of the corresponding cone head limit rod 925, so that the cone head limit rod 925 is released from the plugging of the limit hole 924, and the reset coil spring 923 rotates and resets with the main H-type gear 917 and the slave H-type gear 921, so that the clamping block 922 releases the clamping of the molded part, and the molded part falls into the recovery box 16. After unloading is completed, the electric telescopic cylinder 3 resets the transmission sleeve 4 and the die 6, and at the same time, the recovery coil spring 703 resets the adjustment cylinder 702 and the gear rod 5, and the return coil spring 913 on the bottom pad 912 of the hydraulic cylinder 8 resets and moves with the T-shaped clamping sleeve 914 and the L-shaped push plate 910.
