Description

Technical Field

[0001] The utility model relates to the technical field of punching machines, in particular to an automatic waste removal device for punching machines. Background Art

[0002] In modern industrial production, stamping machines are widely used in various fields, such as automobile manufacturing, electronic equipment production, etc. With the continuous expansion of production scale and the increasing requirements for production efficiency, the cleaning of stamping machine waste has become a key link. Traditional waste cleaning methods are mostly manual cleaning, but manual cleaning is inefficient and there are safety risks. With the development of technology, automatic cleaning devices have emerged. Automatic cleaning devices can clean waste in a timely and effective manner, ensure the continuous operation of stamping machines, and improve production efficiency. At the same time, reasonable waste cleaning device design helps to optimize the layout of production workshops, reduce production costs, and improve the economic benefits and market competitiveness of enterprises.

[0003] Among the existing technologies for removing waste from stamping machines, it is more common to use conveyor belts for waste transportation and cleaning. The conveyor belt system is usually driven by a motor, which drives the active roller to rotate. The friction between the belt and the roller causes the belt to circulate. A conveyor belt is provided under the stamping machine to transport the waste to the designated collection area. Some conveyor belt systems are also equipped with simple guide devices, which are used to ensure the stability of the conveyor belt's running direction, prevent it from running off, and ensure that the waste falls accurately to the collection area.

[0004] The existing method of using conveyor belts for waste cleaning has obvious deficiencies in space utilization. The conveyor belt usually needs to extend from the stamping machine to the waste collection point, which requires reserving a long passage in the workshop for arranging the conveyor belt. In some production workshops with limited space, this long conveyor belt passage occupies a lot of valuable space, which not only makes the workshop layout crowded, but also limits the placement of other equipment and the operating space of personnel. For example, in some small stamping processing plants, limited space is required to place multiple stamping machines and supporting equipment, resulting in a reduction in the available space in the production area, affecting the further improvement of overall production efficiency, and increasing the difficulty of workshop layout planning. For this reason, an automatic waste removal device for stamping machines is proposed to solve the above problems. Utility Model Content

[0036] Reference Figure 1 and Figure 2 The utility model provides an embodiment of an automatic waste removal device for a stamping machine, comprising a device frame 1. The device frame 1 is the core supporting structure of the entire device and is made of high-strength steel. After precise welding and machining processes, it is ensured that it has sufficient strength and stability to bear various forces in the stamping process. The bottom of the device frame 1 is fixedly connected to a rectangular array of support legs 6. The support legs 6 are also made of high-quality steel. A shock-absorbing rubber pad is installed at the bottom, which can effectively absorb the vibration generated when the stamping machine is working and ensure the stability of the device. The top of the device frame 1 is fixedly connected to a hydraulic rod 2. The output end of the hydraulic rod 2 is fixedly connected to an upper mold 3. The top of the device frame 1 is fixedly connected to a lower mold 4. A punching hole 15 is provided inside the lower mold 4. A slide rail 13 is provided inside the device frame 1. The slide rail 13 is made of stainless steel and has a polished surface with a low friction coefficient, which can ensure that a slider 12 slides smoothly inside it. A limiting groove 14 is provided inside the device frame 1. A control component is provided on the outer wall of the device frame 1, which is used to control the device. The device frame 1 is provided with a cleaning component inside, and the cleaning component is used to clean the waste materials after processing. The device frame 1 is provided with a collecting component on the outer wall, and the collecting component is used to collect the waste materials. The cleaning component includes a transmission belt 10, and the outer wall of the transmission belt 10 is fixedly connected with a connecting column 11. The connecting column 11 is made of aluminum alloy, which is light in weight but high in strength. The outer wall of the connecting column 11 is slidably connected to the inside of the limiting groove 14, and the outer wall of the connecting column 11 is rotatably connected with a slider 2 17. The slider 2 17 is made of wear-resistant polytetrafluoroethylene material, which reduces the sliding In order to prevent frictional resistance during movement, a connecting block 19 is provided on the outer wall of the slider 2 17, and a limiting groove 2 18 is provided inside the connecting block 19. The outer wall of the slider 2 17 is slidably connected to the inside of the limiting groove 2 18, and a push rod 16 is fixedly connected to the bottom of the connecting block 19. The push rod 16 is made of stainless steel with a smooth surface and can effectively push the waste to move. The outer wall of the connecting block 19 is fixedly connected to the slider 12, and the inside of the slider 12 is slidably connected to the inside of the slide rail 13, so that the fallen waste is circulated and cleared to both sides of the device, reducing the space occupied by the conveyor belt.

[0037] Specifically, when performing the stamping operation, the operator first places the raw material inside the lower mold 4, and then starts the hydraulic rod 2. The hydraulic rod 2 drives the upper mold 3 to move vertically downward under the action of hydraulic power, so that the upper mold 3 is placed on the raw material in the lower mold 4, and the raw material is stamped. After the stamping process is completed, the waste material generated will fall into the inside of the device frame 1 through the punching hole 15 on the lower mold 4. At this time, after starting the transmission belt 10, the transmission belt 10 drives the connecting column 11 to move. The connecting column 11 moves with the operation of the transmission belt 10, and then drives the slider 2 17 connected to it to move. The slider 2 17 is on the connecting column 11. Under the traction of the drive belt 10, it starts to slide on its running track, thereby driving the connecting block 19 to perform a translational movement. The connecting block 19 drives the push rod 16 to perform a translational movement inside the device frame 1 to clean and push the waste. At the same time, during the movement of the connecting block 19, it also drives the slider 12 to move inside the slide rail 13. When the transmission belt 10 runs to the bend, the connecting column 11 will rotate inside the slider 2 17. Due to the change in the direction of the transmission belt 10 at the bend, the connecting column 11 rotates and drives the slider 2 17 to slide inside the limiting groove 2 18. In this way, the moving direction is adjusted, so that the entire device can be smoothly realized. The circular translation movement, from the push rod 16 continuously working, cleans the waste inside the device frame 1 to the inside of the collection box 9 on both sides for subsequent collection and unified processing, thereby performing a circular swing to push the waste into the collection box 9 on both sides. This method can make full use of the space around the punching machine, especially in a production workshop with limited space. This method does not require a long linear space like a conveyor belt. The collection boxes 9 on both sides can be closely arranged next to the punching machine, making the entire production layout more compact, improving space utilization, and leaving more space for other equipment or operating processes. At the same time, the power usually required for the circular swing mechanism is reduced. It is relatively small, and it mainly relies on the reciprocating motion of the mechanical structure to push the waste. Its movement is relatively simple, and it consumes less energy. Its structure is relatively simple, and it is usually composed of some mechanical parts. The manufacturing and installation costs of these parts are relatively low. It can also push the waste to the collection boxes 9 on both sides more accurately. Since the direction and strength of the swing can be adjusted according to the characteristics of the waste, it can ensure that the waste falls accurately into the collection box 9, reducing the scattering of waste. At the same time, the noise generated during operation is relatively small, it has fewer moving parts, and the movement is relatively smooth, and it will not generate continuous friction and vibration noise like a conveyor belt.

[0038] Reference Figure 1 The control component includes a button 5 and a rotary knob 7. The outer wall of the button 5 is fixedly connected to the outer wall of the device frame 1, and the outer wall of the rotary knob 7 is rotatably connected to the outer wall of the device frame 1.

[0039] Specifically, button 5 and rotary knob 7 are used to start the device. The operation is intuitive and simple. Button 5 can be quickly found and pressed to start the device, which greatly shortens the preparation time before the device is started. Button 5 is used to directly start the main function, and rotary knob 7 is used to adjust some starting parameters. The clear functional division and operation design make it less likely for operators to make misoperations. Compared with some complex and unclear starting methods, this combination can greatly reduce the probability of equipment damage, production interruption and even safety accidents due to misoperation.

[0040] Reference Figure 1 and Figure 3 The collection assembly includes a fixed shell 8 and a collection box 9. The outer wall of the fixed shell 8 is fixedly connected to the outer wall of the device frame 1. The outer walls of the collection box 9 are arranged on both sides of the device frame 1. A fixed groove 27 is provided inside the fixed shell 8. The inner wall of the fixed groove 27 is smooth and has high dimensional accuracy. It is used to guide and accommodate the sliding of the fixed rod 20. The fixed groove 27 is slidably connected to the fixed rod 20. The outer wall of the fixed rod 20 is fixedly connected to the outer wall of the collection box 9. A card slot 28 is provided inside the fixed rod 20. The fixed shell 8 is slidably connected to the mobile rod 22. The outer wall of the mobile rod 22 is rotatably connected to the pull rod 21. A roller 23 is provided on the top of the mobile rod 22. The roller 23 is made of steel and has a chrome-plated surface. It not only ensures strength but also has good wear resistance. Both sides of the roller 23 are rotatably connected with a card column 24. The card column 24 is also made of stainless steel. The top of the card column 24 is processed into a hemispherical shape so that it can slide in more smoothly when it contacts the card slot 28. The outer wall of the card column 24 is slidably connected to the inside of the fixed shell 8. The outer wall of the card column 24 is fixedly connected to the lifting plate 25. The lifting plate 25 is made of aluminum alloy plate, and its surface is anodized to enhance corrosion resistance. The outer wall of the lifting plate 25 is slidably connected to the inside of the fixed shell 8. A spring 26 is arranged inside the fixed shell 8. The top of the spring 26 is fixedly connected to the bottom of the lifting plate 25, and the bottom of the spring 26 is fixedly connected to the inside of the fixed shell 8.

[0041] Specifically, when the raw material is stamped, the moving rod 22 is first pushed. As the moving rod 22 moves horizontally, its inclined surface begins to contact the roller 23. Due to the angle of the inclined surface and the extrusion force generated by the movement, the roller 23 begins to rotate and rise, and the rear roller 23 drives the clamping column 24 to rise together. The rise of the clamping column 24 drives the lifting plate 25 to move upward, thereby stretching the spring 26 and accumulating elastic potential energy. Then the operator moves the collection box 9 to both sides of the device frame 1, so that the fixed rod 20 slides smoothly along the fixed groove 27 opened inside the fixed shell 8. At this time, the collection box 9 is in the initial positioning state, and then the moving rod 22 is pulled by the pull rod 21 to move it in the opposite direction. As the moving rod 22 moves back, the spring 26 begins to rebound, and the spring 26 drives the clamping column 24 to fall rapidly, and the clamping column 24 slides into the inside of the clamping groove 28. Through the close fitting relationship between the clamping column 24 and the clamping groove 28, the collection box 9 is firmly fixed on both sides of the device frame 1. This stable fixing method enables the collection box 9 to withstand the impact force caused by falling waste without shaking or displacement during the operation of the punching machine, thereby collecting waste conveniently and efficiently, laying a solid foundation for subsequent waste processing. At the same time, this fixing method can also be quickly unlocked and removed through simple operating steps when the collection box 9 needs to be replaced or cleaned, thereby improving the flexibility and efficiency of the entire production process.

[0042] Working principle: When stamping the raw material, first push the moving rod 22, and drive its inclined surface to move horizontally through the moving rod 22, and then drive the roller 23 to rotate and rise through the inclined surface of the moving rod 22, and then drive the card column 24 to rise through the roller 23, and then drive the lifting plate 25 to rise through the card column 24, and drive the spring 26 to pull up, and then place the collection box 9 on both sides of the device frame 1, and slide the fixed rod 20 into the fixed groove 27 opened inside the fixed shell 8 through the collection box 9, and then pull the moving rod 22 to move through the pull rod 21, and then drive the card column 24 to fall through the rebound of the spring 26, thereby sliding into the card slot 28, and fixing the collection box 9 on both sides of the device frame 1, so as to facilitate the collection of waste materials. Finally, the raw material is placed inside the lower mold 4, and then the hydraulic rod 2 is started to drive the upper mold through the hydraulic rod 2 3 moves downward to punch the raw material, and the punched waste falls into the inside of the device frame 1 through the punching hole 15, and then the transmission belt 10 is started, and the connecting column 11 is driven to move by the transmission belt 10, and then the slider 2 17 is driven to move by the connecting column 11, and then the connecting block 19 is driven to translate by the slider 2 17, and then the push rod 16 is driven by the connecting block 19 to perform a circular translation inside the device frame 1 to clean the waste, and at the same time, the slider 12 is driven to move inside the slide rail 13 through the connecting block 19. When the transmission belt 10 turns, the connecting column 11 rotates inside the slider 2 17, and drives the slider 2 17 to slide inside the limiting groove 2 18, and then the moving direction can be adjusted, and then the circular translation can be performed to clean the waste inside the device frame 1 and move it to the inside of the collection boxes 9 on both sides for collection and unified treatment.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
