Description

Technical Field

[0002] Automobile parts constitute the overall unit of automobile parts processing and also include various products serving automobile parts processing; in the process of automobile parts processing, stamping is a key process; due to the different shapes, sizes and process requirements of different automobile parts, when performing stamping operations, it is often necessary to frequently replace the corresponding stamping dies.

[0003] The patent with the publication number CN219899944U discloses a stamping device for automobile parts. The device mainly consists of a support plate and a stamping cylinder. An installation groove is opened at the top of the support plate for placing the stamping die. This design realizes the convenient replacement of the stamping die to a certain extent and improves the production efficiency.

[0004] However, the stamping device still has obvious defects in actual use. On the one hand, the device lacks a movable connection mechanism between the stamping head and the stamping cylinder. Given that the stamping die and the stamping head need to be precisely matched, it is inconvenient to synchronously replace the stamping head after replacing the stamping die. On the other hand, with the continuous development of stamping operations, a large amount of heat will be generated due to frequent friction between the punch and the die. If there is no effective heat dissipation measure, the continuous accumulation of heat will cause the temperatures of the punch and the die to continue to rise. This will not only have a negative impact on the quality of the stamped parts, such as causing a decrease in the deformation accuracy of the stamped parts, but also accelerate the wear of the punch and the die, greatly shortening their service lives, thereby reducing the practicability of the entire device.

[0030] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific implementation manners of the present utility model in conjunction with the accompanying drawings of the specification.

[0031] Such as Figure 1 - Figure 3As shown together, this embodiment provides a stamping device for automotive parts. Such a stamping device for automotive parts includes a base 1. A mold 3 is provided on the top of the base 1. A fixing mechanism connected to the mold 3 is provided at the bottom of the base 1. A gantry 2 is provided on the top of the base 1. Hydraulic cylinders 4 are symmetrically provided on the top of the gantry 2. And the telescopic end of the hydraulic cylinder 4 is connected to a punch 6 through a connecting mechanism. Cooling mechanisms are symmetrically provided on the top of the gantry 2. A blanking assembly is provided at the bottom of the base 1; The connecting mechanism includes a connecting seat 5, and the connecting seat 5 is fixedly connected to the telescopic end of the hydraulic cylinder 4. Installation grooves 19 are symmetrically opened at one end of the connecting seat 5. Sliders 7 connected to the punch 6 are slidably installed in the installation grooves 19; The fixing mechanism includes a toothed ring 8, and the toothed ring 8 is rotatably installed below the base 1. First racks 9 meshing with the toothed ring 8 are symmetrically provided at the outer center of the toothed ring 8.

[0032] In this example, the connecting mechanism includes a rotating rod 12. A chamber is provided inside the connecting seat 5. The rotating rod 12 is rotatably installed in the chamber, and the upper end of the rotating rod 12 extends outside the connecting seat 5. A first gear 13 and a torsion spring 15 are sleeved on the outer side of the rotating rod 12 in the chamber, and the torsion spring 15 is located above the first gear 13. Both ends of the torsion spring 15 are fixedly connected to the inner wall of the chamber and the rotating rod 12 respectively. Second racks 14 meshing with the first gear 13 are symmetrically provided at the outer center of the first gear 13. The opposite outer ends of the second racks 14 are both connected to a push plate 16. Plug rods 17 are symmetrically provided on the side of the push plate 16 away from the second rack 14. One end of the plug rod 17 penetrates through one side of the slider 7, so that by twisting the rotating rod 12, the two second racks 14 can be driven to drive the connected push plates 16 to move towards the relative inner sides, and then drive the separation between the plug rod 17 and the slider 7, and the punch 6 can be pulled to drive the slider 7 to slide out of the installation groove 19 to complete the disassembly of the punch 6 for replacement. When installing the punch 6, after twisting the rotating rod 12, the punch 6 can be installed. After installing the slider 7 into the installation groove 19, releasing the force applied to the rotating rod 12 can make the plug rod 17 reset and penetrate through the slider 7 under the torsion of the torsion spring 15, thus completing the installation and fixing of the punch 6.

[0033] In this example, the fixing mechanism further includes a telescopic rod 10, and the telescopic rod 10 is fixedly installed on one side of the bottom of the base 1. The telescopic end of the telescopic rod 10 is fixedly connected to one end of the first rack 9 close to the telescopic rod 10. Sliding grooves 20 are symmetrically provided on the top of the base 1, and the sliding grooves 20 correspond to the first racks 9. Blocks 11 connected to the first racks 9 are slidably installed in the sliding grooves 20. A clamping groove 18 adapted to the block 11 is opened at the bottom of the mold 3. A supporting plate 34 is provided at the bottom of the first rack 9, so that by driving the connected first rack 9 to move through the telescopic rod 10, the other first rack 9 can be driven, so that the two blocks 11 move to the position corresponding to the opening of the clamping groove 18, and then the mold 3 can be disassembled by pulling up, which is convenient for replacement.

[0034] In this example, both the first rack 9 and the clamping block 11 are L-shaped. The inner diameter of the lower opening of the card slot 18 is greater than or equal to the length of one end of the horizontal part of the clamping block 11, so as to use the structure of the clamping block 11 to limit and fix the mold 3.

[0035] As Figure 1 - Figure 2 and Figure 4 - Figure 5 collectively shown, in this example, the cooling mechanism includes a third rack 21, and the third rack 21 is symmetrically arranged on the top of the connecting seat 5. The upper end of the third rack 21 penetrates through the top of the gantry 2. At symmetric positions on the top of the gantry 2, a second gear 22 meshing with the third rack 21 is rotatably installed. At symmetric positions on the top of the gantry 2, a crankshaft 23 is rotatably installed. A third gear 24 meshing with the second gear 22 is sleeved on the outer side of one end of the crankshaft 23. A push rod 26 is hinged to the concave part of the crankshaft 23 through a connecting member 25. Water tanks 28 are symmetrically arranged on the top of the gantry 2 on the opposite outer sides of the push rod 26. A pump barrel 27 is arranged in the water tank 28. One end of the push rod 26 is connected with a piston 29 inside the pump barrel 27. One side of the top of the pump barrel 27 is provided with a water inlet, and a check valve is arranged in the water inlet. The end of the pump barrel 27 away from the push rod 26 is connected with a water outlet pipe 37 with a check valve. The top of the water tank 28 is connected with a water inlet pipe 38. A first cooling cavity 35 is arranged inside the punch 6, and the mold 3 is provided with a second cooling cavity 36. One ends of the water outlet pipe 37 and the water inlet pipe 38 on the left side are respectively connected with the two open ends of the first cooling cavity 35 through quick connectors. One ends of the water outlet pipe 37 and the water inlet pipe 38 on the right side are respectively connected with the two open ends of the second cooling cavity 36 through quick connectors. So that while the third rack 21 moves up and down following the punch 6, the transmission drives the push rod 26 to drive the piston 29 to reciprocate, continuously pushing water to flow through the first cooling cavity 35 and the second cooling cavity 36, and then the punch 6 and the mold 3 can be cooled and temperature-reduced, avoiding the continuous stamping work from causing its own temperature to rise due to friction, thereby affecting the quality of the stamped workpiece.

[0036] In this example, the diameter of the second gear 22 is larger than that of the third gear 24. The top views of the first cooling cavity 35 and the second cooling cavity 36 are both U-shaped. The connecting member 25 is T-shaped, and one end of the connecting member 25 is rotatably sleeved on the outer side of the crankshaft 23. A sealing ring is sleeved on the outer wall of the piston 29 to improve the sealing performance between the piston 29 and the pump barrel 27.

[0037] As Figure 2As shown, in this example, the blanking assembly includes an installation cylinder 30, and the installation cylinder 30 is fixedly installed at the bottom of the base 1. The toothed ring 8 is rotatably sleeved outside the installation cylinder 30, and the support plate 34 is fixedly sleeved outside the installation cylinder 30. A push rod 31 is arranged inside the installation cylinder 30, and the upper end of the push rod 31 penetrates through the mold 3. A baffle 32 and a spring 33 are sleeved on the outside of the push rod 31 inside the installation cylinder 30, and the spring 33 is located on the side of the baffle 32 away from the mold 3. So that after the stamping process is completed, under the action of the baffle 32 and the spring 33, the push rod 31 can be driven to reset and move upward to eject the stamped workpiece for blanking.

[0038] During use, when the punch 6 needs to be disassembled and replaced, the rotating rod 12 can be twisted to rotate, driving the connected first gear 13. At the same time, the rotating rod 12 will twist the torsion spring 15. The rotation of the first gear 13 will drive the second racks 14 engaged on both sides to drive the connected push plate 16, which will drive the insertion rod 17 to move synchronously towards the relatively inner side, so that the insertion rod 17 can be separated from the slider 7. Then, pull the punch 6 to one side to drive the slider 7 out of the installation groove 19, thus completing the disassembly of the punch 6. When installing the punch 6, the above steps can be repeated to move the relatively outer end of the insertion rod 17 between the two installation grooves 19. Then, after installing the slider 7 on the punch 6 into the installation groove 19, release the force applied to the rotating rod 12, and it can reset under the torque of the torsion spring 15, thereby driving the insertion rod 17 to penetrate the slider 7 to complete the installation and fixation of the punch 6 for easy disassembly and replacement of the punch 6. When the mold 3 needs to be replaced, the telescopic rod 10 can be started to push the connected first rack 9, driving the engaged toothed ring 8 to rotate, and then driving the first rack 9 on the other side, so that the two first racks 9 can drive the connected clamping blocks 11 to move towards the relatively inner side, making the clamping blocks 11 move to the position corresponding to the opening of the card slot 18. Then, pull up the mold 3 to disassemble the mold 3. When installing the mold 3, the mold 3 can be installed on the base 1, and the upper end of the clamping block 11 can be inserted into the card slot 18 opened at the bottom of the mold 3. Then, start the telescopic rod 10 to pull the first rack 9 to move, and the transmission drive can be used to make the two clamping blocks 11 move towards the relatively outer side, thereby restricting and fixing the mold 3 for easy disassembly and replacement of the mold 3. During the stamping process of using this equipment, when the hydraulic cylinder 4 drives the punch 6 to move down for stamping or move up for resetting, the connecting seat 5 will drive the connected third rack 21 to move synchronously. The third rack 21 will drive the engaged second gear 22 to rotate. The second gear 22 will drive the engaged third gear 24 to drive the crankshaft 23 to rotate, and then drive the connecting member 25 to continuously push and pull the push rod 26, so that the push rod 26 will drive the piston 29 to reciprocate in the pump cylinder 27, continuously pushing the water entering the pump cylinder 27 through the water outlet pipe 37 to be transported to the first cooling cavity 35 and the second cooling cavity 36, and then transported back to the water tank 28 through the water inlet pipe 38 to form a cycle. The water flowing through the first cooling cavity 35 and the second cooling cavity 36 can be used to cool the punch 6 and the mold 3, thus avoiding the continuous stamping work, resulting in the increase of its temperature due to friction, and further affecting its stamping quality. After the stamping process is completed, when the punch 6 moves up for resetting, the ejector rod 31 will be reset and move up under the action of the baffle 32 and the spring 33, which can push the stamped part up for easy blanking, with convenient use and stronger practicability.

In addition, it should also be understood that after reading the technical content of the present utility model, those skilled in the art can make various changes, modifications and / or variations to the present utility model, and all these equivalent forms also fall within the protection scope defined by the appended claims of this application.
