[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1: Figure 1-Figure 8 As shown, an anti-deviated stamping forming assembly for automobile sheet metal processing includes a mounting bracket 1, the mounting bracket 1 provides a mounting position, a hydraulic cylinder 2 is fixedly connected to the top of the mounting bracket 1, and the hydraulic cylinder 2 serves as a power source, and is used to provide power for stamping forming;

[0032] The output end of the hydraulic cylinder 2 is fixedly connected with a transverse anti-deflection mechanism 3, which is used to prevent the stamping part from lateral deviation. An anti-deflection demoulding mechanism 4 is arranged at the top of the middle part of the mounting frame 1, which is used to demould and prevent the stamping part from longitudinal deviation. A replacement mechanism 5 is arranged on one side of the mounting frame 1, which is used to maintain the installation state of the anti-deflection demoulding mechanism 4.

[0033] The lateral anti-deflection mechanism 3 includes a stabilizing plate 301, which provides installation conditions. The top of the stabilizing plate 301 is fixedly connected to the output end of the hydraulic cylinder 2. A linkage rod 302 is fixedly connected to one side of the stabilizing plate 301. The linkage rod 302 provides an installation position. The bottoms of both ends of the linkage rod 302 are rotatably connected to base rods 303. The base rods 303 can provide a rotation basis. An installation groove 304 is provided inside the base rod 303. The installation groove 304 provides an installation space. A compression spring 1 is fixedly connected inside the installation groove 304. The compression spring 1 provides a reset power. A sliding block 306 is slidably connected inside the installation groove 304. The sliding block 306 plays a role of limiting. A sliding rod 307 is fixedly connected to the bottom of the sliding block 306. The sliding rod 307 plays a role of connection.

[0034] The bottom of the sliding rod 307 is fixedly connected with a mounting plate 308, which serves to connect and rotate. The bottom of the mounting plate 308 is rotatably connected with an anti-deflection plate 309, which can prevent the stamping part from deflecting. The bottom of the anti-deflection plate 309 is rotatably connected with two moving wheels 310. A limiting groove 305 is provided at the top of the middle part of the mounting bracket 1. The moving wheel 310 cooperates with the limiting groove 305 to play a limiting role. The moving wheel 310 is arranged inside the limiting groove 305. The bottom of the compression spring 1 is fixedly connected to the top of the sliding block 306, and the bottom of the anti-deflection plate 309 is slidably connected to the inside of the limiting groove 305.

[0035] During the specific setting, the hydraulic cylinder 2 is started, and the hydraulic cylinder 2 drives the stabilizing plate 301 to move downward, and the stabilizing plate 301 drives the linkage rod 302 to move downward. After the linkage rod 302 moves downward, it can drive the top of the base rod 303 to move downward. Since the anti-deflection plate 309 can only move laterally, under the action of the downward force, the sliding rod 307 and the mounting plate 308 are forced to rotate, so that the mounting plate 308 moves toward the middle, and the mounting plate 308 drives the anti-deflection plate 309 to move toward the middle, which can prevent the stamping part from shifting laterally. At the same time, if the anti-deflection plate 309 is against the outside of the anti-deflection demolding mechanism 4 and the stabilizing plate 301 still needs to move downward, the side sliding rod 307 will move toward the inside of the base rod 303, and the anti-deflection demolding mechanism 4 will produce motion interference with the anti-deflection plate 309.

[0036] Embodiment 2: The anti-biased demoulding mechanism 4 includes a receiving groove 401, which provides an installation position. A sliding plate 402 is slidably connected inside the receiving groove 401, and the sliding plate 402 can be installed inside the receiving groove 401. A base plate 403 is fixedly connected to the top of the sliding plate 402, and the base plate 403 provides an installation position. Both sides of the base plate 403 are fixedly connected with hollow installation columns 404, and the hollow installation columns 404 provide an installation position. A stabilizing rod 405 is fixedly connected to the top of the base plate 403, and the stabilizing rod 405 can provide stability. A movable stopper 406 is fixedly connected to the top of the stabilizing rod 405, and the movable stopper 406 plays a limiting role.

[0037] The outer part of the movable limit stopper 406 is slidably connected with an outer cylinder 407, and the outer cylinder 407 can store oil. An oil outlet hole 408 is opened on the top of the outer cylinder 407, and the oil outlet hole 408 can facilitate the oil outlet. The outer bottom end of the stabilizing rod 405 is sleeved with a compression spring 2, and the compression spring 2 can drive the outer cylinder 407 to automatically reset. The bottom of the outer cylinder 407 is fixedly connected with a connecting plate 410, and both sides of the connecting plate 410 are rotatably connected with connecting rods 411. The top of the connecting rod 411 is rotatably connected with a mounting block 412, and the connecting rod 411 can drive the mounting block 412 to move toward the middle. The bottom of the mounting block 412 is slidably connected to the top of the hollow mounting column 404, and the middle of the mounting block 412 is fixedly connected with a mounting cylinder 413, and the mounting cylinder 413 provides a mounting position;

[0038] The interior of the installation cylinder 413 is fixedly connected with a compression spring 3, and the interior of the installation cylinder 413 is slidably connected with a limiting round block 416, which provides a limiting function, and the side of the limiting round block 416 away from the compression spring 3 is fixedly connected with a connecting cylinder 417, and the side of the connecting cylinder 417 away from the compression spring 3 is fixedly connected with a movable anti-deflection block 418, the top of the outer cylinder 407 is fixedly connected with a push plate 419, and both sides of the top of the base plate 403 are fixedly connected with hollow abutment columns 420;

[0039] The top of one of the hollow abutment columns 420 is fixedly connected with an oil pipe 421, which serves as a connection. The top of the oil pipe 421 is fixedly connected to the inside of the oil outlet hole 408. The four corners of the top of the base plate 403 are fixedly connected with a limit rod 422, which improves stability. The outer sleeve of the limit rod 422 is provided with a compression spring 4;

[0040] A lower punch 424 is slidably connected between the outsides of the four limit rods 422, a sliding slot 425 is provided inside the bottom end of the stabilizing plate 301, a sliding plate 409 is slidably connected inside the sliding slot 425, a round rod 414 is fixedly connected to the bottom of the sliding plate 409, an upper punch 415 is fixedly connected to the bottom of the round rod 414, four corners of the upper punch 415 are slidably connected to the outsides of the limit rods 422, a baffle 423 is fixedly connected to the top of the limit rods 422, and a push plate 419 is slidably connected to the inside of the lower punch 424;

[0041] Liquid is arranged inside one of the hollow abutment columns 420, a side of the compression spring 3 close to the movable anti-deflection block 418 is fixedly connected to a side of the limiting round block 416 away from the movable anti-deflection block 418, the middle part of the connecting plate 410 is slidably connected to the outside of the stabilizing rod 405, and the outside of the stabilizing rod 405 passes through the bottom of the outer cylinder 407;

[0042] The connecting rod 411 passes through the outside of the hollow mounting column 404, the tops of the four compression springs 404 are fixedly connected to the bottom of the four corners of the lower punch 424, and the top of the hollow abutment column 420 is fixedly connected with a protective pad;

[0043] When the stabilizing plate 301 moves downward, it can drive the sliding plate 409 to move downward, and then drive the upper punch 415 to move downward through the round rod 414. When the round rod 414 contacts the stamping part on the top of the lower punch 424, the lower punch 424 will move downward, and at the same time, it can move the ejecting plate 419 into the interior of the lower punch 424. The ejecting plate 419 drives the outer cylinder 407 to move downward, and the outer cylinder 407 drives the connecting rod 411 to move downward, so that the mounting block 412 can be driven to move toward the middle. After the mounting block 412 moves toward the middle, it drives the mounting cylinder 413 to move toward the middle.

[0044] The movable anti-deflection block 418 is driven to move toward the middle by the limiting circular block 416 and the connecting cylinder 417, thereby preventing the stamping part from moving longitudinally. In order to prevent the motion interference between the movable anti-deflection block 418 and the stamping part, when the movable anti-deflection block 418 contacts the stamping part and the ejector plate 419 still needs to move downward, the connecting cylinder 417 moves toward the inside of the mounting cylinder 413, thereby preventing the motion interference from occurring. As the outer cylinder 407 moves downward, the movable limiting plug 406 is used to squeeze the liquid inside the outer cylinder 407 into the inside of the oil pipe 421 through the oil outlet hole 408, and then enters the inside of the hollow stop column 420 through the oil pipe 421.

[0045] When the bottom of the lower punch 424 moves to the top of the hollow pillar 420, the lower punch 424 will not move downward any further. At this time, the upper punch 415 moves downward to stamp the stamping part at the top of the lower punch 424.

[0046] After the stamping is completed, the hydraulic cylinder 2 is started again, and the upper punch 415 is driven to move upward by the slide plate 409 and the round rod 414 through the output end of the hydraulic cylinder 2. When the upper punch 415 leaves the stamping part, the connecting plate 410 is driven to move upward under the reaction force of the compression spring 2, and the connecting plate 410, the outer cylinder 407 and the ejecting plate 419 can be moved upward, forcing the ejecting plate 419 to slide out of the interior of the lower punch 424, and the stamping part is ejected from the interior of the lower punch 424, so as to facilitate the removal of the part.

[0047] At the same time, when the push plate 419 moves upward, the liquid inside the hollow column 420 can be pumped into the outer cylinder 407 through the oil pipe 421. Since the oil outlet hole 408 and the oil pipe 421 are relatively thin, the speed of the liquid entering the outer cylinder 407 can be controlled, so that the outer cylinder 407 moves upward slowly, preventing the push plate 419 from moving upward quickly and causing damage to the stamping parts in the lower punch 424.

[0048] Embodiment 3: The replacement mechanism 5 includes a receiving groove 501, which provides an installation position. The receiving groove 501 is opened on one side of the middle part of the installation fixing frame 1. A plurality of compression springs 5 ​​are fixedly connected inside the receiving groove 501. The compression springs 5 ​​can provide a power for resetting. A sliding limit plate 503 is slidably connected inside the receiving groove 501. The sliding limit plate 503 plays a role of limiting.

[0049] The top of the sliding limit plate 503 is fixedly connected with a blocking plate 502, and the blocking plate 502 has the function of blocking the sliding plate 402. The tops of the plurality of compression springs 5 ​​are fixedly connected to the bottom of the sliding limit plate 503. The outer sleeve of the blocking plate 502 is provided with a rubber sleeve. When the anti-bias demoulding mechanism 4 is disassembled;

[0050] When setting it specifically, first move the blocking plate 502 downward to drive the sliding limit plate 503 to move downward, and then move the sliding plate 402 out of the receiving groove 401. Therefore, when the sliding plate 402 moves to the outside of the receiving groove 401, the base plate 403, the limit rod 422, the upper punch 415 and the round rod 414 drive the sliding plate 409 to move out of the sliding groove 425, and the disassembly of the anti-bias demoulding mechanism 4 is completed.

[0051] During installation, since the top outer side of the blocking plate 502 is a curve, when the sliding plate 402 is directly inserted into the interior of the receiving groove 401, the blocking plate 502 will move downward under the action of the extrusion force. When the sliding plate 402 is completely moved into the interior of the receiving groove 401, the sliding limit plate 503 and the blocking plate 502 are driven to move upward under the action of the compression spring five, and then the blocking plate 502 can be used to support the sliding plate 402 and prevent it from moving outward.

[0052] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
