Description

Technical Field

[0001] This utility model belongs to the technical field of punching devices, and in particular relates to a hinge punching device. Background Technology

[0002] Hinges, as key components enabling the rotational connection of parts, are in huge demand. With the continuous improvement of product quality and assembly precision requirements, more stringent specific requirements are placed on the machining precision of hinges, especially the holes used for connection on the hinge. The dimensional and positional accuracy of these holes directly affects the assembly effect and service life of the hinge. Existing technologies typically include a machining table, a punching mechanism, and a feeding mechanism. The feeding mechanism transports the hinge to the punching position, and then the punching mechanism completes the punching operation. Some devices use manual assisted feeding, where the operator places the hinge in the designated position and then starts punching. Other devices use a simple mechanical feeding structure to achieve semi-automated production.

[0003] Traditional feeding mechanisms lack precise positioning structures, and hinges are prone to shifting during feeding, leading to inaccurate punching positions. This is because hinge dimensions vary, and simple placement or conveying cannot guarantee that they are in the preset precise position during punching, thus affecting subsequent assembly. Most existing equipment does not have a dedicated, efficient cleaning mechanism, and metal shavings generated during punching remain on the processing table and punching mechanism. The accumulation of shavings not only affects the accuracy of subsequent punching but may also scratch the hinge surface, reducing product quality. Furthermore, cleaning these shavings requires additional manpower and time, further impacting production efficiency.

[0004] To address these issues, we provide a hinge punching device. Utility Model Content

[0005] The purpose of this utility model is to provide a hinge punching device, which solves the problems of lack of precise positioning structure in the feeding mechanism, easy displacement of the hinge during feeding, and lack of a dedicated high-efficiency cleaning mechanism in the prior art by cooperating the punching mechanism, feeding mechanism and cleaning mechanism.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a hinge punching device, comprising a processing table, a punching mechanism fixedly connected to the rear end of the top of the processing table, a feeding mechanism fixedly connected to the front end of the top of the processing table, and a cleaning mechanism provided at the bottom of the processing table. The feeding mechanism includes a mounting frame, one side of which is fixedly connected to the processing table, and a first cylinder fixedly connected to one side of the mounting frame. A punching platform is fixedly connected to one side of the first cylinder. Positioning grooves are provided on both sides of the top of the punching platform, and punching holes are provided at the top of the positioning grooves. The first cylinder is fixed to one side of the mounting frame and can drive the punching platform to move according to a preset trajectory and speed. The first cylinder controls the start, stop, and movement of the punching platform. The dynamic distance ensures accurate feeding of the hinge, guaranteeing that the hinge reaches the punching position precisely. The punching table, as the component supporting the hinge, has positioning grooves on both sides of its top that are adapted to the shape of the hinge. When the hinge is placed in the positioning groove, the positioning groove can effectively limit the hinge, preventing lateral or longitudinal displacement during feeding and punching. The punching holes on the top of the positioning grooves correspond to the punching components of the punching mechanism. During punching, the punching components can accurately pass through the punching holes to punch the hinge, ensuring the accuracy of the punching position. The smooth edges of the punching holes prevent wear on the punching components during punching and also prevent irregular hole openings from affecting the punching quality.

[0008] The present invention is further configured such that the punching mechanism includes a fixed plate, the bottom of which is fixedly connected to the processing table, a column fixedly connected to the top of the fixed plate, and a mounting plate fixedly connected to the top of the column. A second cylinder is fixedly connected to the front end of the top of the mounting plate. The bottom of the second cylinder extends through to the bottom of the mounting plate and is fixedly connected to a punching head mechanism. The column at the top of the fixed plate connects the fixed plate and the mounting plate, forming a stable frame structure that can withstand the impact force generated when the second cylinder and the punching head mechanism are working. The mounting plate provides a reliable mounting platform for the second cylinder, ensuring the stability of the second cylinder during operation. The second cylinder can drive the punching head mechanism to move up and down precisely, achieving efficient punching of the hinge on the punching table and ensuring the consistency of punching quality.

[0009] The present invention is further configured such that the cleaning mechanism includes a base plate, the top of which is fixedly connected to a processing table, a connecting plate fixedly connected to one side of the processing table, a motor fixedly connected to one side of the connecting plate, a lead screw fixedly connected to the output end of the motor, a threaded sleeve threadedly connected to one side of the lead screw, a connecting block fixedly connected to the bottom of the threaded sleeve, and a cleaning plate fixedly connected to the bottom of the connecting block. One side of the cleaning plate extends to the surface of the base plate. When the lead screw fixed to the output end of the motor rotates, it drives the threaded sleeve to move, which in turn drives the cleaning plate to move on the surface of the base plate through the connecting block, thereby realizing automatic cleaning of debris on the base plate without manual cleaning, saving labor costs and improving work efficiency. The cleaning plate extends to the surface of the base plate, which can fully cover the base plate and ensure thorough cleaning of debris.

[0010] The present invention is further configured such that a through groove is provided on the top of the processing table, and the through groove is located below the punching head mechanism. During the punching process, the generated debris can fall directly onto the bottom plate below through the through groove, avoiding the accumulation of debris on the top of the processing table and affecting subsequent processing operations. It also facilitates the cleaning mechanism to clean the debris in a concentrated manner and keep the top of the processing table clean.

[0011] The present invention is further configured such that the stamping head mechanism includes a mounting base, the top of the mounting base is fixedly connected to the second cylinder, and stamping seats are fixedly connected to both sides of the bottom of the mounting base. A stamping column that cooperates with the stamping hole is fixedly connected to the bottom of the stamping seat. The top of the mounting base is fixedly connected to the second cylinder, and the stamping seats on both sides of the bottom are connected to the stamping column, so that the stamping column is subjected to uniform force. The stamping column cooperates with the stamping hole of the punching table, which can accurately punch holes at the preset position of the hinge, ensuring the accuracy of the punching position and avoiding hole position deviation that affects the assembly and use of the hinge.

[0012] The present invention is further configured such that slide rails are fixedly connected to both sides of the top of the processing table, and the bottom of the punching table is slidably connected to the slide rails. The slide rails are slidably connected to the bottom of the punching table, which guides the movement of the punching table, so that the punching table moves smoothly along a straight line under the drive of the first cylinder, avoiding the punching table from deviating or shaking during the feeding process, and ensuring that the hinge can be accurately delivered to the punching position.

[0013] The present invention is further configured such that both sides of the cleaning plate are provided with bending portions, one side of the bending portion is slidably connected to both sides of the base plate, and the bending portion is slidably connected to both sides of the base plate, which plays a limiting and guiding role in the movement of the cleaning plate, so that the cleaning plate remains stable during the movement and will not deviate from the surface of the base plate, ensuring that the cleaning plate can always be in close contact with the base plate and completely push the debris to the designated position.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model uses a first cylinder to drive the punching table to move smoothly, realizing automatic feeding of the hinge, reducing manual intervention and improving feeding efficiency. The positioning groove on the top of the punching table can accurately position the hinge and prevent the hinge from shifting during the punching process. The punching hole and the punching column cooperate to ensure the accuracy of the punching position and effectively improve the processing accuracy of the hinge. The mounting base connects the second cylinder and the punching base. The punching column at the bottom of the punching base cooperates with the punching hole on the punching table to ensure the dimensional accuracy of the punching.

[0016] 2. This utility model uses a motor to drive the lead screw to rotate, which in turn moves the threaded sleeve, connecting block, and cleaning plate. This allows for the automatic cleaning of punching debris on the surface of the base plate. The bent parts on both sides of the cleaning plate are slidably connected to the sides of the base plate, ensuring the smooth movement of the cleaning plate. At the same time, it concentrates the debris in the middle area of ​​the base plate, making it easy to collect and process. This avoids the impact of debris accumulation on processing accuracy and product quality, reduces the workload of manual cleaning, and improves the continuity and efficiency of production.

Detailed Implementation

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figure 1-5 This utility model is a hinge punching device, including a processing table 1. A punching mechanism 2 is fixedly connected to the rear end of the top of the processing table 1, and a feeding mechanism 3 is fixedly connected to the front end of the top of the processing table 1. A cleaning mechanism 4 is provided at the bottom of the processing table 1. The feeding mechanism 3 includes a mounting frame 31. One side of the mounting frame 31 is fixedly connected to the processing table 1. A first cylinder 32 is fixedly connected to one side of the mounting frame 31. A punching table 33 is fixedly connected to one side of the first cylinder 32. Positioning grooves 34 are provided on both sides of the top of the punching table 33, and a punching hole 35 is provided on the top of the positioning groove 34.

[0027] Specifically: The first cylinder 32 is fixed on one side of the mounting bracket 31 and can drive the punching table 33 to move according to the preset trajectory and speed. The first cylinder 32 controls the start, stop and movement distance of the punching table 33 to achieve accurate feeding of the hinge and ensure that the hinge can accurately reach the punching position. As a component that carries the hinge, the punching table 33 has positioning grooves 34 on both sides of its top that are adapted to the shape of the hinge. When the hinge is placed in the positioning groove 34, the positioning groove 34 can effectively limit the hinge and prevent the hinge from shifting laterally or longitudinally during feeding and punching. The punching hole 35 on the top of the positioning groove 34 corresponds to the punching component of the punching mechanism 2. During punching, the punching component can accurately pass through the punching hole 35 to punch the hinge, ensuring the accuracy of the punching position. The smooth edge of the punching hole 35 avoids wear on the punching component during punching and also prevents the punching quality from being affected by irregular hole openings.

[0028] Example 2

[0029] Please see Figure 1-5Based on Embodiment 1, the punching mechanism 2 includes a fixed plate 21, the bottom of which is fixedly connected to the processing table 1. A column 22 is fixedly connected to the top of the fixed plate 21, and a mounting plate 23 is fixedly connected to the top of the column 22. A second cylinder 24 is fixedly connected to the front end of the top of the mounting plate 23. The bottom of the second cylinder 24 extends through to the bottom of the mounting plate 23 and is fixedly connected to a punching head mechanism 25. The cleaning mechanism 4 includes a base plate 41, the top of which is fixedly connected to the processing table 1. A connecting plate 42 is fixedly connected to one side of the processing table 1. A motor 43 is fixedly connected to one side of the connecting plate 42. A lead screw 44 is fixedly connected to the output end of the motor 43. A threaded sleeve 45 is threadedly connected to one side of the surface of the lead screw 44. The bottom of the threaded sleeve 45... A connecting block 46 is fixedly connected to the bottom of the connecting block 46, and a cleaning plate 47 is fixedly connected to the bottom of the connecting block 46. One side of the cleaning plate 47 extends to the surface of the bottom plate 41. A through groove 5 is provided on the top of the processing table 1. The through groove 5 is located below the stamping head mechanism 25. The stamping head mechanism 25 includes a mounting base 251. The top of the mounting base 251 is fixedly connected to the second cylinder 24. A stamping seat 252 is fixedly connected to both sides of the bottom of the mounting base 251. A stamping column 253 that cooperates with the stamping hole 35 is fixedly connected to the bottom of the stamping seat 252. A slide rail 6 is fixedly connected to both sides of the top of the processing table 1. The bottom of the punching table 33 is slidably connected to the slide rail 6. A bending part is provided on both sides of the cleaning plate 47. One side of the bending part is slidably connected to both sides of the bottom plate 41.

[0030] Specifically: The column 22 at the top of the fixed plate 21 connects the fixed plate 21 and the mounting plate 23, forming a stable frame structure capable of withstanding the impact force generated when the second cylinder 24 and the punching head mechanism 25 are working. The mounting plate 23 provides a reliable mounting platform for the second cylinder 24, ensuring the stability of the second cylinder 24 during operation. The second cylinder 24 can drive the punching head mechanism 25 to move up and down precisely, achieving efficient punching of the hinge on the punching table 33 and ensuring consistent punching quality. The lead screw 44 fixed at the output end of the motor 43 rotates... When activated, the threaded sleeve 45 moves, which in turn moves the cleaning plate 47 on the surface of the base plate 41 via the connecting block 46. This achieves automatic cleaning of debris on the base plate 41, eliminating the need for manual cleaning, saving labor costs, and improving work efficiency. The cleaning plate 47 extends to the surface of the base plate 41, fully covering it and ensuring thorough debris removal. The through slot 5 is located below the punching head mechanism 25. During the punching process, debris generated can fall directly onto the base plate 41 below through the through slot 5, preventing debris from accumulating on the top of the processing table 1 and affecting its operation. Subsequent processing operations also facilitate the centralized cleaning of debris by the cleaning mechanism 4, keeping the top of the processing table 1 clean. The top of the mounting base 251 is fixedly connected to the second cylinder 24, and the stamping seats 252 on both sides of the bottom are connected to the stamping columns 253, so that the stamping columns 253 are evenly stressed. The stamping columns 253 are used in conjunction with the stamping holes 35 of the punching table 33 to accurately punch holes at the preset position of the hinge, ensuring the accuracy of the punching position and avoiding hole position deviations that affect the assembly and use of the hinge. The slide rail 6 is slidably connected to the bottom of the punching table 33. The movement of the punching table 33 is guided, allowing it to move smoothly in a straight line under the drive of the first cylinder 32. This prevents the punching table 33 from shifting or shaking during the feeding process, ensuring that the hinge can accurately deliver the material to the punching position. The bent part is slidably connected to both sides of the base plate 41, which limits and guides the movement of the cleaning plate 47, ensuring that the cleaning plate 47 remains stable during movement and does not deviate from the surface of the base plate 41. This ensures that the cleaning plate 47 is always in close contact with the base plate 41, thoroughly pushing the debris to the designated position.

[0031] The working principle of this utility model is as follows: Before punching, the hinge to be punched is placed in the positioning groove 34. The positioning groove 34 is adapted to the shape of the hinge and can effectively limit the hinge, preventing the hinge from shifting laterally or longitudinally during subsequent feeding and punching. The first cylinder 32 is started to drive the punching table 33 to move. The first cylinder 32 controls the start, stop and movement distance of the punching table 33, accurately delivering the hinge to the bottom of the punching mechanism 2, ensuring that the hinge is in the preset punching position. When the hinge reaches the designated punching position, the second cylinder 24 is started, and its bottom drives the punching head mechanism 25 to move downward. With the push of the second cylinder 24, the punching column 253 passes through the punching hole 35 and punches the hinge in the positioning groove 34.

[0032] The debris generated during the punching process will fall directly onto the bottom plate 41 of the processing table 1 through the through slot 5 at the top of the processing table 1, thus preventing the debris from accumulating on the top of the processing table 1 and affecting subsequent processing. After punching is completed, the second cylinder 24 drives the punching head mechanism 25 to reset upwards, and the first cylinder 32 drives the punching table 33 to move in the opposite direction, sending out the completed hinge. At the same time, the placement and feeding operation of the next hinge can be carried out.

[0033] After the motor 43 starts, its output end drives the lead screw 44 to rotate. The threaded sleeve 45 on the surface of the lead screw 44 moves under the action of the rotation of the lead screw 44. Through the connecting block 46 at the bottom, it drives the cleaning plate 47 to move on the surface of the base plate 41, and pushes the debris on the base plate 41 to the designated position for centralized processing. The cleaning plate 47 extends to the surface of the base plate 41 and can fully cover the base plate 41, ensuring that the debris is thoroughly cleaned without the need for manual cleaning, thus saving labor costs.
