Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to an automatic cleaning device for stamping dies of automotive parts. Background Technology

[0002] Stamping dies for automotive parts are process equipment used in the automotive manufacturing industry. They apply pressure through stamping technology to cause metal or non-metal materials to undergo plastic deformation or separation in the die in order to produce automotive parts of the required shape and size. They are an indispensable and important tool in modern automobile manufacturing.

[0003] During the stamping process of automotive parts, a large amount of waste is generated. However, the traditional waste disposal mainly relies on manual collection and cleaning. Manual waste cleaning is inefficient and increases the labor intensity of workers. Moreover, after long-term use, dirt such as grease and metal shavings easily accumulate on the surface of the stamping head, affecting the normal operation of the stamping head, leading to mold damage and a decline in the quality of stamped parts. In order to solve the above problems, the inventor proposes an automatic cleaning device for automotive parts stamping dies. Utility Model Content

[0004] In order to solve the problem of automatic cleaning of stamping dies for automotive parts, the purpose of this utility model is to provide an automatic cleaning device for stamping dies for automotive parts.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: an automatic cleaning device for stamping dies of automotive parts, including a base plate, a lower die fixedly connected to the top of the base plate, the lower die having a discharge hole, a waste bin corresponding to the discharge hole being opened below the lower die, a discharge hopper being arranged inside the waste bin and below the discharge hole, the discharge hopper being inclined to the horizontal plane and fixedly connected to each other, the discharge hopper being slidably connected to the base plate via a sliding plate, a vibration discharge assembly being arranged on one side of the lower die, the vibration discharge assembly being used to vibrate and discharge waste, an L-shaped plate being fixedly connected to the top of the base plate near the lower die, an upper die being fixedly installed below the L-shaped plate, a stamping head being arranged at the bottom of the upper die, a flushing mechanism being arranged at the bottom of the L-shaped plate near the upper die, the flushing mechanism being used to clean the stamping head, a hydraulic rod being fixedly installed at the top of the L-shaped plate, the piston rod of the hydraulic rod being fixedly connected to the upper die.

[0006] Preferably, the vibratory unloading assembly includes a fixed plate, which is fixedly connected to the top of the base plate near the slide plate. A telescopic rod is fixedly connected to the side of the slide plate near the fixed plate. The end of the telescopic rod away from the slide plate movably passes through the fixed plate and is connected to a fixed block. A spring is provided between the fixed block and the fixed plate. The spring is movably sleeved on the outside of the telescopic rod. A fixed block is fixedly connected to one side of the upper mold. A roller is rotatably connected to the bottom end of the L-shaped rod. An inclined guide block is fixedly connected to one side of one of the discharge hoppers. The bottom end of the L-shaped rod slides along the top end of the inclined guide block.

[0007] Preferably, the flushing mechanism includes a piston cylinder, which is fixedly connected to one side of the bottom of the L-shaped plate. A piston plate is slidably connected inside the piston cylinder, and a piston rod is fixedly connected to the top of the piston plate. A horizontal plate is fixedly connected to one side of the upper mold, and the horizontal plate is fixedly connected to the piston rod. A horizontal plate is opened on one side of the top of the piston cylinder, and a gooseneck tube is fixedly connected to one side of the top of the piston cylinder and at a position corresponding to the horizontal plate. The nozzle of the gooseneck tube corresponds to the position of the punching head.

[0008] Preferably, a guide rod is fixedly connected to one side of the base plate, and a slider is fixedly connected to the bottom of the front end of the discharge hopper, with the slider slidably engaged with the outside of the guide rod.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. The upper mold moves downward, driving the L-shaped rod and roller to move downward synchronously. The inclined guide block guides the movement of the discharge hopper, while pushing the discharge hopper to move horizontally along the top of the base plate. This causes the fixed block to move towards the side of the spring and compress the spring. Since the discharge hopper is inclined to the horizontal plane, the waste material falling on the discharge hopper is pushed by the horizontal component force and moves a distance towards the inclined plane of the discharge hopper under the action of inertia. When the upper mold returns to its original position, the spring force is used to reset the discharge hopper. This process is repeated to achieve automatic unloading of waste material, further reducing the labor intensity of workers.

[0011] 2. When the upper die moves downward, it simultaneously moves the horizontal plate, piston rod, and piston plate downward. At the same time, air enters the piston cylinder through the horizontal plate and is positioned above the piston plate. When the upper die moves upward, it simultaneously moves the piston plate upward, compressing the air inside the piston cylinder and causing the air to be sprayed onto the surface of the punch head through the gooseneck tube. This cleans the dirt adhering to the surface of the punch head, preventing the dirt accumulated on the punch head from affecting its normal operation. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1-5As shown, this utility model provides an automatic cleaning device for stamping dies of automotive parts, including a base plate 1, a lower die 2 fixedly connected to the top of the base plate 1, a discharge hole 4 opened in the lower die 2, a waste bin 3 corresponding to the discharge hole 4 opened below the lower die 2, a discharge hopper 5 arranged inside the waste bin 3 and below the discharge hole 4, the discharge hopper 5 is inclined to the horizontal plane and fixedly connected to each other, the discharge hopper 5 is slidably connected to the base plate 1 through a sliding plate 13, a vibration discharge assembly 6 is arranged on one side of the lower die 2, the vibration discharge assembly 6 is used to vibrate and discharge the waste, an L-shaped plate 8 is fixedly connected to the top of the base plate 1 near the lower die 2, an upper die 9 is fixedly installed below the L-shaped plate 8, a stamping head 10 is arranged at the bottom of the upper die 9, a flushing mechanism 7 is arranged at the bottom of the L-shaped plate 8 near the upper die 9, the flushing mechanism 7 is used to clean the stamping head 10.

[0021] The vibratory unloading assembly 6 includes a fixed plate 61, which is fixedly connected to the top of the base plate 1 near the side of the slide plate 13. A telescopic rod 62 is fixedly connected to the side of the slide plate 13 near the fixed plate 61. The end of the telescopic rod 62 away from the slide plate 13 moves through the fixed plate 61 and is connected to a fixed block 63. A spring 64 is provided between the fixed block 63 and the fixed plate 61. The spring 64 is movably sleeved on the outside of the telescopic rod 62. A fixed block 63 is fixedly connected to one side of the upper mold 9. A roller 66 is rotatably connected to the bottom end of the L-shaped rod 65. An inclined guide block 67 is fixedly connected to one side of one of the discharge hoppers 5. The bottom end of the L-shaped rod 65 slides along the top end of the inclined guide block 67.

[0022] By adopting the above technical solution, when the upper die 9 is stamping the parts, the upper die 9 moves downward, driving the L-shaped rod 65 and the roller 66 to move downward synchronously. When the roller 66 moves to contact the inclined surface of the inclined guide block 67, the inclined guide block 67 guides the movement of the discharge hopper 5, and pushes the discharge hopper 5 to move horizontally along the top of the bottom plate 1, thereby driving the fixed block 63 to move to one side of the spring 64 and compressing the spring 64. Since the discharge hopper 5 is inclined to the horizontal plane, the waste material falling on the discharge hopper 5 is subjected to the horizontal component force and moves a distance towards the inclined surface of the discharge hopper 5 under the action of inertia. When the upper die 9 is reset, the elastic force of the spring 64 is used to reset the discharge hopper 5. This process is repeated to realize the automatic unloading operation of waste material.

[0023] The flushing mechanism 7 includes a piston cylinder 71, which is fixedly connected to one side of the bottom of the L-shaped plate 8. A piston plate 72 is slidably connected inside the piston cylinder 71. A piston rod 73 is fixedly connected to the top of the piston plate 72. A horizontal plate 74 is fixedly connected to one side of the upper mold 9. The horizontal plate 74 is fixedly connected to the piston rod 73. A horizontal plate 74 is opened on one side of the top of the piston cylinder 71. A gooseneck tube 75 is fixedly connected to one side of the top of the piston cylinder 71 and at a position corresponding to the horizontal plate 74. The nozzle of the gooseneck tube 75 corresponds to the position of the stamping head 10.

[0024] By adopting the above technical solution, when the upper die 9 moves downward, it simultaneously drives the horizontal plate 74, piston rod 73 and piston plate 72 to move downward. At the same time, air enters the interior of the piston cylinder 71 through the horizontal plate 74 and is located above the piston plate 72. When the upper die 9 moves upward, it simultaneously drives the piston plate 72 to move upward, compressing the air inside the piston cylinder 71 and causing the air to be sprayed onto the surface of the punch head 10 through the gooseneck tube 75, cleaning the dirt attached to the surface of the punch head 10.

[0025] A guide rod 11 is fixedly connected to one side of the base plate 1, and a slider 12 is fixedly connected to the bottom of the front end of the discharge hopper 5. The slider 12 is slidably engaged with the outside of the guide rod 11.

[0026] By adopting the above technical solution, the movement of the discharge hopper 5 is guided by the cooperation between the slider 12 and the guide rod 11, thereby improving the stability of the discharge hopper 5 when it moves laterally.

[0027] A hydraulic rod 14 is fixedly installed at the top of the L-shaped plate 8, and the piston rod of the hydraulic rod 14 is fixedly connected to the upper mold 9.

[0028] By adopting the above technical solution, the upper die 9 is driven to press through the extension and retraction of the piston rod of the hydraulic rod 14.

[0029] Working principle: When cleaning up the waste generated from automotive parts, the waste generated during the stamping process falls through the unloading hole 4 onto the top of the discharge hopper 5. When the upper die 9 is stamping the parts, the upper die 9 moves downward, driving the L-shaped rod 65 and the roller 66 to move downward synchronously. When the roller 66 moves to contact the inclined surface of the inclined guide block 67, the inclined guide block 67 guides the movement of the discharge hopper 5 and pushes the discharge hopper 5 to move horizontally along the top of the base plate 1, thereby driving the fixed block 63 to move to one side of the spring 64 and compressing the spring 64. Since the discharge hopper 5 is inclined to the horizontal plane, the waste falling on the discharge hopper 5 is pushed by the horizontal component force and moves a distance towards the inclined surface of the discharge hopper 5 under the action of inertia. When the upper die 9 resets, the elastic force of the spring 64 is used to reset the discharge hopper 5. This process is repeated to realize the automatic unloading operation of the waste.

[0030] Simultaneously, when the upper die 9 moves downward, it also drives the horizontal plate 74, piston rod 73, and piston plate 72 to move downward. At the same time, air enters the interior of the piston cylinder 71 through the horizontal plate 74 and is located above the piston plate 72. When the upper die 9 moves upward, it also drives the piston plate 72 to move upward, compressing the air inside the piston cylinder 71 and causing the air to be sprayed onto the surface of the punch head 10 through the gooseneck tube 75, cleaning the dirt attached to the surface of the punch head 10.

[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
