Description

Technical Field

[0001] This utility model relates to the field of machine housing processing technology, and in particular to a continuous stamping device for pushing machine housings. Background Technology

[0002] As a crucial component of electronic or mechanical equipment, the housing primarily protects internal components, provides structural support, and facilitates the overall aesthetic design of the product. In modern manufacturing, particularly in consumer electronics, communication equipment, and automotive electronics, the processing quality and efficiency of the housing directly impact the performance and production costs of the entire product. Stamping, as a highly efficient and precise metal forming process, is widely used in housing manufacturing. It involves applying pressure to sheet metal using molds and stamping equipment, causing plastic deformation to obtain parts of the desired shape and size.

[0003] In the stamping process of machine casings, the stamping device, as one of the key pieces of equipment, has a decisive impact on production efficiency, processing accuracy, and operational safety due to its performance and degree of automation. Especially in the core link of ensuring the continuity of material feeding and stamping, existing stamping devices have gradually revealed a series of obvious limitations and technical problems. Utility model patent CN215745792U discloses a stamping device for machine casing processing, including a support base. A groove is formed in the middle of the upper surface of the support base. A support frame is fixedly connected to the outside of the support base. A positioning component is installed inside the support base, and safety components are installed on the left, right, and front surfaces of the support base. This utility model, by incorporating the positioning component, allows the motor within the positioning component to rotate the lead screw. Both the first and second positioning rods move the positioning plate towards the center, fixing the object in place. This is suitable for objects of different specifications. Operators can set a safety sensing distance value for the first and second reflective photoelectric sensors in the safety component. These sensors can detect whether someone is nearby; an alarm light will sound when someone approaches, preventing danger during stamping.

[0004] Although the device improves its applicability by incorporating positioning components and enhances operational safety through safety features, it still has significant shortcomings in practical applications. Specifically, existing stamping equipment is not conducive to continuous feeding and stamping of casing materials during casing processing. Operators must manually place each piece of material into the stamping area before processing, which not only increases labor intensity but also significantly reduces stamping efficiency. Furthermore, the intermittent processing method easily leads to uncoordinated production cycles, affecting the connection of subsequent processes and failing to meet the actual needs of modern high-volume, high-efficiency production. Therefore, to address the numerous shortcomings of existing technologies, we urgently need an innovative continuous casing pushing stamping device to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a continuous stamping device for pushing and pressing machine housings, which solves the problem that in the existing stamping equipment, it is not convenient to continuously feed and stamp the machine housing material during the processing of machine housings. Operators need to manually place each piece of material into the stamping area one by one before processing can be carried out, which not only increases the labor intensity but also greatly reduces the stamping efficiency.

[0006] To achieve the above objectives, this utility model provides a continuous stamping device for pushing a housing, including a frame, and conveyor rollers rotatably connected to both sides of the inner side of the frame, with two conveyor belts wound and connected between the two conveyor rollers, and a gap between the two conveyor belts.

[0007] A top frame is fixedly connected to the top of the frame, and a stamping plate is provided at the top between the two conveyor belts. A hydraulic cylinder is fixedly connected to one side of the top of the top frame by bolts. The output shaft of the hydraulic cylinder passes through the top of the top frame and is fixedly connected to the top of the stamping plate. A U-shaped limiting plate is provided on the inner side of the top frame, and a first cylinder is fixedly connected to one side of the top of the top frame by bolts. The output shaft of the first cylinder passes through the top of the top frame and is fixedly connected to the top of the U-shaped limiting plate. The two ends of the U-shaped limiting plate are respectively located at the top of the two conveyor belts. Support plates are provided on the inner side of the two conveyor belts, and both sides of the support plates are fixedly connected to the inner wall of the frame.

[0008] One end of each of the two conveying rollers is rotatably connected to the inner wall of the frame via a rotating shaft, and the other end of each of the two conveying rollers passes through the side wall of the frame via a bearing sleeve. A drive motor is fixedly connected to one side of the outer wall of the frame by bolts, and one end of one of the conveying rollers is connected to the output shaft of the drive motor.

[0009] The U-shaped limiting plate has sliders fixedly connected to both sides, and the two sliders are slidably connected to the inner wall of the top frame through a sliding groove. Several protrusions are fixedly connected to the bottom of the U-shaped limiting plate.

[0010] The two conveyor belts are connected by a push plate, and a fixed plate is fixedly connected to one side of the frame. A second cylinder is fixedly connected to one side of the fixed plate by bolts. The output shaft of the second cylinder passes through the fixed plate and is fixedly connected to one side of the push plate. The push plate is located on the top of the support plate.

[0011] The frame has a cleaning plate that slides on the lower inner side, and a support rod is fixedly connected to one side of the cleaning plate.

[0012] The cleaning plate has sliding blocks fixedly connected to both sides, and both sliding blocks are slidably connected to the inner wall of the frame through sliding grooves.

[0013] This utility model discloses a continuous stamping device for pushing a casing. By setting up two conveyor belts and the gap structure between them, along with conveyor rollers, it realizes the automatic continuous material conveying function, avoiding the inefficiency caused by traditional manual material placement, and significantly improving the overall stamping efficiency. At the same time, the design of the first cylinder driving the U-shaped limiting plate to press and fix the material effectively solves the problems of low stamping accuracy and poor product consistency caused by unstable material positioning, and improves the quality stability of stamped products. The stamping plate is driven by a hydraulic cylinder to complete the stamping action. Combined with the structural support and guiding function provided by the top frame, it further enhances the stability and controllability of the stamping process. The setting of the support plate provides solid reverse support force for the stamping process, preventing the material from collapsing or deforming during the stress process, thereby improving the forming quality of the product. The overall structure is compact and highly automated, which not only reduces the labor intensity of operators, but also improves the coordination of production rhythm, meeting the actual needs of modern mass production and high-efficiency production.

Detailed Implementation

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1-5 A continuous stamping device for pushing a housing includes a frame 1, and two conveyor rollers 11 are rotatably connected to the inner sides of the frame 1. Two conveyor belts 10 are wound and connected between the two conveyor rollers 11, and there is a gap between the two conveyor belts 10. A top frame 2 is fixedly connected to the top of the frame 1, and a stamping plate 4 is provided on the top between the two conveyor belts 10. A hydraulic cylinder 3 is fixedly connected to one side of the top of the top frame 2 by bolts. The output shaft of the hydraulic cylinder 3 passes through the top of the top frame 2 and is fixedly connected to the top of the stamping plate 4. A U-shaped limiting plate 6 is provided on the inner side of the top frame 2, and a first cylinder 5 is fixedly connected to one side of the top of the top frame 2 by bolts. The output shaft of the first cylinder 5 passes through the top of the top frame 2 and is fixedly connected to the top of the U-shaped limiting plate 6. The two ends of the U-shaped limiting plate 6 are respectively located on the top of the two conveyor belts 10. A support plate 13 is provided on the inner side of the two conveyor belts 10, and both sides of the support plate 13 are fixedly connected to the inner wall of the frame 1.

[0023] First, the housing material to be stamped is placed on the conveyor belt 10, and the material is conveyed forward by the operation of the conveyor belt 10. The gap between the two conveyor belts 10 is used to position the parts of the material that need to be stamped, ensuring accurate stamping position. When the material is conveyed to the top of the support plate 13 and the bottom of the stamping plate 4, the first cylinder 5 is activated, and its output shaft pushes the U-shaped limiting plate 6 downward. The two ends of the U-shaped limiting plate 6 are respectively located at the top of the two conveyor belts 10, thereby applying downward pressure to the material and firmly clamping it between the conveyor belt 10 and the U-shaped limiting plate 6, achieving effective fixation of the material. Subsequently, the hydraulic cylinder 3 is activated, and its output shaft drives the stamping plate 4 to move downward. The stamping plate 4 moves precisely downward in the guide direction within the top frame 2. The fixed material is stamped into shape. After stamping, the hydraulic cylinder 3 is reset, causing the stamping plate 4 to return to its original position. At the same time, the first cylinder 5 also drives the U-shaped limiting plate 6 to rise, releasing the clamping force on the material. At this time, the conveyor belt 10 continues to operate, sending out the stamped material and sending the next piece of material to be processed into the stamping area, thereby realizing continuous feeding and stamping operations. Throughout the process, the support plate 13 is set on the inner side of the conveyor belt 10, and its two sides are fixedly connected to the inner wall of the frame 1, which can provide a stable support foundation for the material and prevent the material from deforming or shifting during the stamping process. In addition, the conveyor rollers 11 are rotatably connected to the inner sides of the frame 1, so that the conveyor belt 10 can run smoothly and ensure the stability and continuity of the material conveying process.

[0024] Furthermore, one end of each of the two conveyor rollers 11 is rotatably connected to the inner wall of the frame 1 via a rotating shaft, and the other end of each of the two conveyor rollers 11 passes through the side wall of the frame 1 via a bearing sleeve. A drive motor 12 is fixedly connected to one side of the outer wall of the frame 1 by bolts. One end of one of the conveyor rollers 11 is connected to the output shaft of the drive motor 12. The drive motor 12 directly drives one of the conveyor rollers 11 to rotate through the output shaft, thereby realizing the automatic and continuous conveying of materials through the conveyor belt 10. This achieves efficient and stable material feeding without manual intervention, greatly improving production efficiency.

[0025] Furthermore, sliders 7 are fixedly connected to both sides of the U-shaped limiting plate 6, and both sliders 7 are slidably connected to the inner wall of the top frame 2 through the sliding groove 8. Several protrusions 9 are fixedly connected to the bottom of the U-shaped limiting plate 6. When the first cylinder 5 is started, it can ensure that the U-shaped limiting plate 6 moves accurately downward along the direction of the sliding groove 8, applying uniform pressure to the material, achieving the effect of firmly clamping the material, avoiding the stamping deviation problem caused by unstable material positioning, and improving the processing accuracy and product consistency.

[0026] Furthermore, a push plate 19 is provided between the two conveyor belts 10, and a fixed plate 17 is fixedly connected to one side of the frame 1. A second cylinder 18 is fixedly connected to one side of the fixed plate 17 by bolts. The output shaft of the second cylinder 18 passes through the fixed plate 17 and is fixedly connected to one side of the push plate 19. The push plate 19 is located at the top of the support plate 13. When the first cylinder 5 is started, it can ensure that the U-shaped limit plate 6 moves accurately down along the direction of the slide 8, apply uniform pressure to the material, achieve the effect of firmly clamping the material, avoid the stamping deviation problem caused by unstable material positioning, and improve the processing accuracy and product consistency.

[0027] Furthermore, a cleaning plate 14 is slidably connected to the lower inner side of the frame 1, and a support rod 20 is fixedly connected to one side of the cleaning plate 14. The operator can pull the support rod 20 to move the cleaning plate 14 along the sliding groove 16, so as to conveniently remove the waste or debris that falls to the bottom of the frame 1. This achieves the effect of keeping the inside of the equipment clean, reducing the occurrence of failures, extending the service life of the equipment, and maintaining a good working environment.

[0028] Furthermore, sliding blocks 15 are fixedly connected to both sides of the cleaning plate 14, and both sliding blocks 15 are slidably connected to the inner wall of the frame 1 through sliding grooves 16. While the U-shaped limiting plate 6 moves downward to press the material, the protrusion 9 can increase the friction on the material surface, better preventing the material from sliding or shifting during the stamping process, thereby enhancing the material's fixing stability and improving the stamping quality. At the same time, this design also takes into account the needs of materials of different thicknesses, and has a certain degree of versatility and flexibility.

[0029] In summary:

[0030] Before use, the material to be processed is placed on the conveyor belt 10, and the drive motor 12 is started. The output shaft of the motor drives one of the conveyor rollers 11 to rotate. Since the two conveyor rollers 11 are connected by the conveyor belt 10, the other conveyor roller 11 also rotates synchronously, driving the conveyor belt 10 to run and conveying the material forward with the conveyor belt 10. The gap between the two conveyor belts 10 is used to accurately position the area in the material that needs to be stamped, ensuring that the stamping position is accurate. When the material is conveyed to the top of the support plate 13 and below the stamping plate 4, the first cylinder 5 is activated, pushing the U-shaped limiting plate 6 downward. Sliding blocks 7 are fixed on both sides of the U-shaped limiting plate 6 and are slidably set in the sliding grooves 8 on the top frame 2, thereby ensuring that the U-shaped limiting plate 6 moves vertically downward and stably clamps the material. At the same time, several protrusions 9 are fixed at the bottom of the U-shaped limiting plate 6. These protrusions 9 increase the friction on the surface of the material and further prevent the material from slipping during the stamping process. After the material is securely clamped, the hydraulic cylinder 3 is activated, and its output shaft drives the stamping plate 4 to press down precisely along the direction of the top frame 2, completing the stamping of the material. After stamping, the hydraulic cylinder 3 is reset, the stamping plate 4 rises, and then the first cylinder 5 drives the U-shaped limit plate 6 to rise, releasing the clamping of the material. At this time, the conveyor belt 10 continues to run, sending out the stamped material and sending the next piece of material to be processed into the stamping area. To further improve the discharge efficiency, a push plate 19 is provided on the top of the support plate 13. The second cylinder 18 is connected to the push plate 19 through the fixed plate 17. After one stamping is completed, the push plate 19 can be pushed to quickly push the finished product out of the workstation, freeing up space for the next process. In addition, in order to keep the inside of the equipment clean and reduce mechanical failures caused by the accumulation of waste, the cleaning plate 14 is slidably connected to the sliding groove 16 through the sliding block 15 and installed on the lower inner side of the frame 1, and is pulled by the support rod 20, which makes it convenient for operators to regularly clean up debris and residue.Through the coordinated design of the conveyor belt 10 and the conveyor roller 11, combined with the driving method of the drive motor 12, continuous material feeding is achieved, solving the inefficiency problem caused by the need for manual placement of materials one by one in traditional technology, and significantly improving the overall stamping cycle and production efficiency. Secondly, the linkage mechanism between the U-shaped limiting plate 6 and the first cylinder 5, combined with the guiding structure of the slider 7 and the slide groove 8, ensures that the material can be stably clamped before stamping, avoiding the problem of increased product defect rate due to material slippage or displacement, and improving stamping accuracy and product consistency. Furthermore, the protrusion 9 set at the bottom of the U-shaped limiting plate 6 enhances the fixing ability of the material, which is not only suitable for... The device is designed for materials of varying thicknesses, enhancing its adaptability and versatility. Furthermore, the design of the second cylinder 18 and push plate 19 effectively enables automatic material discharge after stamping, reducing manual intervention and accelerating production. The support plate 13 provides a reliable support foundation for the material, preventing deformation or collapse during stamping and ensuring product quality. Finally, the cleaning assembly, consisting of the cleaning plate 14, sliding block 15, sliding groove 16, and support rod 20 located at the bottom of the frame 1, facilitates regular cleaning of internal residues, helping to extend equipment lifespan, reduce maintenance frequency, improve the operating environment, and enhance overall stability and safety. Overall, this device is compact and highly automated, effectively solving problems such as the inability to achieve continuous stamping, low processing efficiency, and unstable positioning in existing technologies. It also optimizes the operating process, reduces labor intensity, and meets the demands of modern manufacturing for efficient, stable, and intelligent production.
