DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-6 As shown, a stamping device for the production and processing of automobile parts includes an operating table 1. A groove 7 is formed in the middle of the operating table 1. A punch 2 is installed in the groove 7. A fixing structure 8 is installed on the groove 7. The fixing structure 8 includes a positioning rod 801. Two positioning rods 801 are installed in the groove 7. Two card slots 802 are formed in the punch 2. The two positioning rods 801 are respectively engaged with the two card slots 802. A plurality of convex blocks 805 are arranged in a circumferential array on the outer circumference of the punch 2. A stopper 804 abuts against the convex blocks 805. The bottom end of the stopper 804 is fixedly connected to a limiting ring 803. The limiting ring 803 is rotatably connected in the groove 7. The stopper 804 has an "L" - shaped structure. A baffle 806 is fixedly connected to one side of the stopper 804. The baffle 806 abuts against the side of the convex block 805. An upper die 3 is arranged in cooperation with the punch 2 above the punch 2. When installing the punch 2, align the card slots 802 on the punch 2 with the positioning rods 801, and then move the punch 2 downward to engage the card slots 802 with the positioning rods 801, so as to realize the rapid positioning of the punch 2 and prevent the punch 2 from moving left and right. Then, snap the limiting ring 803 into the groove 7, and then rotate the limiting ring 803 so that the stopper 804 on the limiting ring 803 abuts against the adjacent convex blocks 805 on the punch 2. At the same time, the baffle 806 on one side of the stopper 804 abuts against the side of the convex block 805, making the limiting ring 803 unable to rotate further, thereby further fixing the punch 2 and preventing the punch 2 from moving upward. Thus, the punch 2 can be quickly installed on the operating table 1. The operation is flexible and convenient, improving the installation efficiency. When it is necessary to replace the punch 2 with different sizes, rotate the limiting ring 803 so that the stopper 804 no longer abuts against the convex blocks 805, which facilitates the disassembly and replacement of the punch 2. When replacing, only the punch 2 needs to be disassembled, and there is no need to replace the bottom plate together, thus saving the production cost.

[0024] As a technical optimization solution of the present utility model, both the positioning rod 801 and the card slot 802 have a "T" - shaped structure, and the top end of the positioning rod 801 has a trapezoidal structure. The trapezoidal structure at the top end of the positioning rod 801 facilitates the engagement of the positioning rod 801 with the card slot 802.

[0025] As a technical optimization solution of the utility model, a limiting structure 9 is installed on the operating table 1. The limiting structure 9 includes a pressing ring 901. The pressing ring 901 is installed on the operating table 1. The bottom end of the pressing ring 901 is rotatably connected to the limiting ring 803. A limiting rod 902 is slidably connected to the pressing ring 901. Two limiting holes 906 are formed in the limiting ring 803. The limiting rod 902 is engaged in one of the limiting holes 906. The top end of the limiting rod 902 is fixedly connected to a connecting plate 904. A guiding rod 905 is fixedly connected to the pressing ring 901. The connecting plate 904 is slidably connected to the guiding rod 905. A tension spring 903 is sleeved on the guiding rod 905. The bottom end of the tension spring 903 is fixedly connected to the pressing ring 901. The top end of the tension spring 903 is fixedly connected to the connecting plate 904. When it is necessary to replace the punch 2 of different sizes, the connecting plate 904 is pulled upward. The connecting plate 904 drives the limiting rod 902 to slide out of the limiting hole 906. At the same time, the connecting plate 904 drives the tension spring 903 to elongate, so as to release the fixation of the limiting ring 803. Then the limiting ring 803 is rotated backward, so that the stopper 804 no longer abuts against the convex block 805. Then the connecting plate 904 is released. The tension spring 903 resets and drives the limiting rod 902 to slide downward at the same time. At this time, the limiting ring 803 abuts against the limiting rod 902, and the tension spring 903 is not fully reset. Then the limiting ring 803 is slightly rotated until the other limiting hole 906 on the limiting ring 803 is aligned with the limiting rod 902. After losing the abutting force, the tension spring 903 is fully reset, driving the limiting rod 902 to engage into the other limiting hole 906, so that the limiting ring 803 cannot rotate, and further the stopper 804 does not affect the disassembly of the punch 2, making the disassembly of the punch 2 more convenient and flexible.

[0026] As a technical optimization solution of the utility model, four fixing rods 4 are installed on the operating table 1. A driving structure 5 is installed on the fixing rods 4. The driving structure 5 includes a second fixing plate 502. The same second fixing plate 502 is installed on the four fixing rods 4. The top end of the second fixing plate 502 abuts against a fixing cap 503. The fixing cap 503 is threadedly connected to the top end of the fixing rod 4. A hydraulic cylinder 504 is installed in the middle of the second fixing plate 502. The extending end of the hydraulic cylinder 504 is fixedly connected to the first fixing plate 501. The first fixing plate 501 is slidably connected to the fixing rod 4. The female die 3 is installed on the bottom surface of the first fixing plate 501. The hydraulic cylinder 504 is started. The hydraulic cylinder 504 extends downward, and at the same time drives the first fixing plate 501 to slide downward on the fixing rod 4. The first fixing plate 501 drives the female die 3 to move downward. After the female die 3 abuts against the raw material of the clutch housing, it continues to move downward until it is engaged with the punch 2, so that the clutch housing is stamping formed, thus completing the stamping work of the clutch housing, with flexible operation and high stamping efficiency.

[0027] As a technical optimization solution of the present utility model, a shock-absorbing structure 6 is installed at the bottom end of the first fixing plate 501. The shock-absorbing structure 6 includes a support rod 601. Four support rods 601 are installed at the bottom end of the first fixing plate 501. The bottom end of the support rod 601 is slidably connected to an installation sleeve 604. A spring 603 is fixedly connected inside the installation sleeve 604. The top end of the spring 603 is fixedly connected to the bottom surface of the support rod 601. Four connection sleeves 602 are fixedly connected to the operation table 1. The support rod 601 is slidably connected to the connection sleeve 602. During the downward movement of the driving structure 5, the support rod 601 is driven to move downward, so that the support rod 601 slides into the connection sleeve 602. When the fixing cap 503 at the bottom end of the support rod 601 abuts against the connection sleeve 602, the fixing cap 503 slides upward on the support rod 601, and at the same time, the spring 603 is abutted and contracted. When the driving structure 5 vibrates during the reciprocating stamping process, the support rod 601 reciprocates in the connection sleeve 602, and at the same time, the fixing cap 503 reciprocates on the support rod 601. The spring 603 undergoes elastic deformation during the movement of the fixing cap 503. The four springs 603 can play a role in shock absorption and protection for the stamping equipment, avoiding damage to the components on the stamping equipment due to large vibrations, thereby effectively improving the safety of use.

[0028] When the utility model is in use, first, the positioning rod 801 and the pressing ring 901 are installed on the operating table 1 through bolts, so that the limiting ring 803 is rotatably connected to the operating table 1. When installing the punch 2, the card slot 802 on the punch 2 is aligned with the positioning rod 801, and then the punch 2 is moved downward to engage the card slot 802 with the positioning rod 801, thereby realizing the rapid positioning of the punch 2, preventing the punch 2 from moving left and right. Pull the connecting plate 904 upward, and the connecting plate 904 drives the limiting rod 902 to slide out of the limiting hole 906. At the same time, the connecting plate 904 drives the tension spring 903 to elongate, thereby releasing the fixation of the limiting ring 803. Rotate the limiting ring 803 so that the stopper 804 on the limiting ring 803 abuts against the adjacent convex block 805 on the punch 2. At the same time, the baffle 806 on one side of the stopper 804 abuts against the side of the convex block 805, making the limiting ring 803 unable to rotate further, thereby further fixing the punch 2 and preventing the punch 2 from moving upward. Thus, the punch 2 is quickly installed on the operating table 1, with flexible and convenient operation and improved installation efficiency. At this time, the limiting rod 902 corresponds to another limiting hole 906, and the limiting rod 902 engages with this limiting hole 906 to limit the limiting ring 803, further increasing the stability of the fixing structure 8 for fixing the punch 2 and making the installation effect of the punch 2 better. When it is necessary to replace the punch 2 with different sizes, pull the connecting plate 904 upward, and the connecting plate 904 drives the limiting rod 902 to slide out of the limiting hole 906. At the same time, the connecting plate 904 drives the tension spring 903 to elongate, thereby releasing the fixation of the limiting ring 803. Then rotate the limiting ring 803 back so that the stopper 804 no longer abuts against the convex block 805. Then release the connecting plate 904, and the tension spring 903 resets and drives the limiting rod 902 to slide downward. At this time, the limiting ring 803 abuts against the limiting rod 902, and the tension spring 903 is not fully reset. Then slightly rotate the limiting ring 803 until another limiting hole 906 on the limiting ring 803 is aligned with the limiting rod 902. After losing the abutting force, the tension spring 903 fully resets and drives the limiting rod 902 to engage with another limiting hole 906, thereby making the limiting ring 803 unable to rotate, and further making the stopper 804 not affect the disassembly of the punch 2, making the disassembly of the punch 2 more convenient and flexible. And when replacing, only the punch 2 needs to be disassembled, without replacing the bottom plate together, thereby saving production costs. Start the hydraulic cylinder 504, and the hydraulic cylinder 504 extends downward, and at the same time drives the first fixing plate 501 to slide downward on the fixing rod 4. The first fixing plate 501 drives the die 3 to move downward. After the die 3 abuts against the raw material of the clutch housing, it continues to move downward until it engages with the punch 2, making the clutch housing stamping formed, thereby completing the stamping work of the clutch housing, with flexible operation and high stamping efficiency;During the downward movement of the driving structure 5, the support rod 601 is driven to move downward, causing the support rod 601 to slide into the connecting sleeve 602. When the fixing cap 503 at the bottom end of the support rod 601 abuts against the connecting sleeve 602, the fixing cap 503 slides upward on the support rod 601, and at the same time, the abutting spring 603 contracts. When the driving structure 5 vibrates during the reciprocating stamping process, the support rod 601 reciprocates in the connecting sleeve 602, and at the same time, the fixing cap 503 reciprocates on the support rod 601. The spring 603 undergoes elastic deformation during the movement of the fixing cap 503. The four springs 603 can play a role in shock absorption and protection for the stamping equipment, preventing the components on the stamping equipment from being damaged due to excessive vibration, thereby effectively improving the safety of use.
