Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die for automobile parts with good stability. Background Art

[0002] Auto parts, including chassis and exhaust pipes, require groove processing through stamping. Existing stamping dies include conveying devices, stamping modules, and drive equipment, which enable continuous stamping of multiple groups of auto parts.

[0003] When the stamping module performs stamping processing on automobile parts under the control of the driving equipment, the automobile parts will be pushed by a large external force. At present, the conveying device is only provided with a limit device to limit the automobile parts from both sides. Under this condition, multiple groups of automobile parts can still slide between the limit devices, resulting in poor overall fixation effect of the automobile parts. When the stamping module is removed, the automobile parts will move simultaneously with the stamping module in close contact with it, causing the automobile parts to be suspended on the conveying device. Later, when the automobile parts fall to the surface of the conveying device under the action of their own gravity, the position will change, causing the automobile parts to collide with the limit device on the transmission device, causing damage to the automobile parts and affecting the processing accuracy of the automobile parts. In view of the shortcomings of the existing technology, we propose a stamping die for automobile parts with good stability to solve the above problems. Utility Model Content

[0031] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. 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 making any creative efforts are within the scope of protection of the present invention.

[0032] The embodiment of the present application solves the problem of unstable connection between automobile parts and the conveying device at the stamping die, which causes automobile parts to be damaged under the influence of collision, by providing an automobile parts stamping die with good stability, and realizes a stable connection between automobile parts and the conveying device at the stamping die.

[0033] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0034] The embodiment of the utility model discloses a stamping die for automobile parts with good stability.

[0035] According to the attached Figure 1-6 As shown, it includes a stamping die base 1, a conveying roller 11 rotatably arranged on the inner wall of the stamping die base 1, multiple groups of conveyor belts 12 arranged on the outer wall of the conveying roller 11, a stand 2 arranged on the top of the stamping die base 1, a stamping module 21 arranged at the lower part of the stand 2, and a control cylinder 22 arranged on the top of the stand 2. Under the limit drive of the multiple groups of cylinders 22, the moving path of the stamping module 21 can be limited, so that the overall stamping process of the stamping die is relatively stable. Figure 1-2 , multiple groups of automobile parts are placed in sequence on the top of multiple groups of conveyor belts 12 set at the stamping die base 1, so that under the conveying action of the conveyor belt 12, multiple groups of automobile parts are moved in sequence to the bottom of the stamping module 21, and then the cylinder 22 is controlled to push the stamping module 21 downward, so that the stamping module 21 performs a stamping operation on the surface of the automobile parts. After the stamping is completed, the cylinder 22 is controlled to drive the stamping module 21 to move upward. At this time, the conveyor belt 12 is opened again, so that the stamped automobile parts can be discharged with the assistance of the conveyor belt 12.

[0036] A positioning plate 3 is provided on the top of the conveyor belt 12, and a hydraulic cylinder for driving the position change of the positioning plate 3 is provided on the top of the stamping die base 1. Figure 1 By setting the positioning plate 3, the position of the automobile parts on the surface of the transmission belt 12 can be limited from the left and right directions. Figure 3 When the height of the automobile parts is smaller than the height of the positioning plate 3, since the top of the positioning plate 3 is provided with an opening corresponding to the size of the stamping module 21, the downward movement path of the stamping module 21 will not be blocked by the positioning plate 3, so that the stamping module 21 can fit tightly with the automobile parts, making the stamping module 21 more stable during the stamping process.

[0037] A negative pressure mechanism 4 is provided in the stamping die base 1. Through the provided negative pressure mechanism 4, a group of automobile parts located at the lower part of the stamping module 21 can be further fixed to the conveyor belt 12, so that a group of automobile parts will not be offset during the stamping process. The negative pressure mechanism 4 includes a negative pressure pump 41. The negative pressure pump 41 is provided at the lower part of the stamping die base 1. The negative pressure pump 41 can be fixed to the ground by a threaded fixing member, etc. The threaded fixing member is not specifically drawn in the drawings. A fixing member for fixing the stamping parts to the conveyor belt 12 is provided on the top of the negative pressure pump 41. The adsorption member 42 is positioned between the conveyor belts 12, and a cavity 13 is provided between two adjacent groups of conveyor belts 12. One end of the adsorption member 42 is limitedly inserted into the interior of the cavity 13, and the top of the adsorption member 42 is flush with the top of the conveyor belt 12. The controller 43 is provided on one side of the stand 2. The controller 43 is electrically connected to the negative pressure pump 41. A press switch 44 for opening and closing the negative pressure pump 41 is provided on one side of the controller 43, and a groove 431 for installing the press switch 44 is provided on one side of the controller 43. Figure 4-6 When a group of automobile parts are conveyed to the bottom of the stamping module 21, the control cylinder 22 drives the stamping module 21 and the guide blocks 45 arranged on both sides of the stamping module 21 to move downward. The guide blocks 45 are fixedly connected to the outer wall of the stamping module 21. A connecting groove 451 is provided on one side of the guide block 45. A spherical block 46 for opening and closing the press switch 44 is provided inside the connecting groove 451. A spring 47 is provided inside the guide block 45. The connection position between the spherical block 46 and the press switch 44 is automatically adjusted by the spring 47. The inner wall of the connecting groove 451 is slidably connected to the limit plate 5. The spherical block 46 and the limit plate 5 are fixedly connected. A telescopic rod 51 is provided between one side of the limit plate 5 and the inner wall of the connecting groove 451. The spring 47 is sleeved on the outer wall of the telescopic rod 51.

[0038] When the guide block 45 moves to the position corresponding to the press switch 44, please refer to the attached Figure 6 At this time, the spherical block 46 in the guide block 45 is not blocked by the side wall of the stand 2. The spherical block 46 moves to the inside of the groove 431 under the elastic force of the spring 47, and the spherical block 46 presses the press switch 44 set in the groove 431 once, so that the press switch 44 is turned on, so that the negative pressure pump 41 controlled by it runs, so that negative pressure is generated in the adsorption member 42 at the negative pressure pump 41, and then a group of automobile parts are adsorbed and fixed on the transmission belt 12. Then, the stamping module 21 and the guide block 45 continue to move downward under the drive of the control cylinder 22, so that the spherical block 46 in the guide block 45 gradually moves out of the groove 431. When the spherical block 46 is completely moved out, the stamping module 21 and a group of automobile parts gradually approach each other. At this time, the stamping module 21 that continues to move downward can perform a stamping operation on a group of automobile parts.

[0039] After the stamping of a group of automobile parts is completed, the stamping module 21 and the guide block 45 are moved upward by the control cylinder 22. During this process, the negative pressure pump 41 is still in operation. When the guide block 45 on one side of the stamping module 21 moves to the position corresponding to the press switch 44, please refer to the attached Figure 6 At this time, the spherical block 46 in the guide block 45 is not blocked by the side wall of the stand 2. The spherical block 46 moves to the inside of the groove 431 again under the elastic force of the spring 47, and the spherical block 46 presses the press switch 44 set inside the groove 431 again, so that the press switch 44 is closed, and the negative pressure pump 41 stops running, thereby freeing a group of automobile parts from negative pressure control. Then, the conveyor belt 12 is turned on to discharge the group of automobile parts after stamping.

[0040] The inner wall of the stand 2 is fixedly connected to a guide frame 6, and one end of the guide block 45 is limitedly slid inside the guide frame 6. The setting of the guide frame 6 and the guide block 45 can further limit the movement of the stand of the stamping module 21.
