Description

Technical Field

[0001] This utility model relates to the field of punching machine technology, and in particular to a fixed-length punching machine. Background Technology

[0002] Punching is a common process in the processing of metal sheets, profiles, and other workpieces. Its purpose is to machine through holes or blind holes at predetermined locations on the workpiece to meet subsequent assembly and connection requirements. To achieve efficient and precise punching operations, fixed-length punching machines are widely used in industrial production.

[0003] A standard-length punching machine typically includes a frame, a length-fixing mechanism for positioning the workpiece, a bottom support assembly for supporting the workpiece, and punching execution components (such as the punch and drive unit). The bottom support assembly's function is to support the workpiece from below during the punching process, preventing deformation or displacement due to punching pressure, thus ensuring punching accuracy and stability. In practical applications, the support points of the bottom support assembly are often fixed, and their settings are usually based on standard punching requirements or the common dimensions of most workpieces.

[0004] However, in actual production, different customers have significantly different requirements for punching workpieces. Not only may the number and diameter of holes differ, but the punching position often needs to be customized according to the specific application scenario. When the punching position required by the customer overlaps with the fixed support point of the bottom support component, it will cause interference between the punching execution component and the support point during operation: on the one hand, the support point will block the normal downward path of the punch, preventing the punch from reaching the preset punching position and directly affecting the completion of the punching operation; on the other hand, if punching is forced, it may cause a rigid collision between the punch and the support point, resulting in damage to the punch and support component, and even affecting the operational stability of the entire equipment. In view of this, this utility model proposes a fixed-length punching machine. Utility Model Content

Two fixed blocks are fixedly connected to the bottom of the adjusting block. A rotating shaft is rotatably connected in the two fixed blocks.

[0011] Optionally, a first servo motor is installed at the bottom of the adjusting block, and the output end of the first servo motor is fixedly connected with the rotating shaft.

[0012] Optionally, a tail plate is fixedly connected to one end of a group of fixed rods away from the connecting block. A threaded rod is threadedly connected in the tail plate, and the threaded rod is rotatably connected with the adjusting block.

[0013] Optionally, the moving component includes a guide rail fixedly connected to the top of the fixed rod. Multiple groups of sliders are slidably connected on the guide rail.

[0014] Optionally, a second servo motor is installed on one of the horizontal plates. The output end of the second servo motor passes through the horizontal plate and is fixedly connected to a gear.

Combined with the adjustability of the support component, the equipment can meet the customized punching position requirements of different customers while ensuring the accuracy of length-fixed punching. This greatly improves the equipment's adaptability to diverse production needs, simplifies the operation process, and improves production efficiency.

[0019] In summary, this invention can avoid interference caused by the overlap of the punching position and the support point, ensure smooth punching, reduce equipment damage and maintenance costs, improve the adaptability of the equipment to diverse needs and the ease of operation, and increase production efficiency.

[0034] Example

[0035] like Figure 1 As shown, the present invention proposes a fixed-length punching machine, which includes two sets of symmetrically arranged fixed rods 1. Multiple sets of support frames 11 are fixedly connected to the bottom of the two sets of fixed rods 1. A connecting block 12 is fixedly connected to one end of the two sets of fixed rods 1. The positions of the fixed rods 1, the support frames 11 and the connecting blocks 12 are fixed.

[0036] For further details, please refer to Figure 1 and Figure 2 The aforementioned punching machine includes a support assembly 2 mounted on two sets of fixed rods 1, which supports the sheet metal. The support assembly 2 includes multiple mounting plates 21 positioned between the two sets of fixed rods 1. Two sets of positioning plates 22 are fixedly connected to the top of each mounting plate 21, and guide rollers 23 are rotatably connected between the two sets of positioning plates 22. The sheet metal is placed on top of the guide rollers 23. The rotating guide rollers 23 reduce the friction of the sheet metal, facilitating its placement from one end of the fixed rod 1 onto the support assembly 2. First limiting blocks 24 are fixedly connected to both ends of each mounting plate 21. The first limiting blocks 24 are slidably connected to the fixed rods 1, allowing the mounting plate 21 to move smoothly. A connecting plate 25 is provided on the side of each fixed rod 1 away from the mounting plate 21. The connecting plate 25 is fixedly connected to the multiple sets of first limiting blocks 24. When the connecting plate 25 moves, the multiple sets of first limiting blocks 24 drive the multiple mounting plates 21 to move synchronously, facilitating changes in the position of the guide rollers 23 and preventing the guide rollers 23 from coinciding with the punching position. A transition plate 26 is fixedly connected to one end of the connecting plate 25. A first push rod motor 27 is installed on the side of the fixed rod 1, one layer away from the connecting plate 25. The output end of the first push rod motor 27 is fixedly connected to the transition plate 26. After the first push rod motor 27 is started, it drives the connecting plate 25 to move through the transition plate 26.

[0037] Furthermore, the aforementioned punching machine includes positioning mechanisms 3 located at both ends of the sheet metal. These positioning mechanisms 3 are used to position the sheet metal. Each positioning mechanism 3 includes a first clamping plate 31 fixedly connected to the top of the connecting block 12. An adjusting block 32 is located at the end of the sheet metal away from the first clamping plate 31. The adjusting block 32 is slidably connected between two sets of fixed rods 1. Second limiting blocks 33 are fixedly connected to both ends of the adjusting block 32, and these second limiting blocks 33 are slidably connected to the fixed rods 1. The adjusting block 32 moves smoothly due to the limiting effect of the second limiting blocks 33. Two sets of fixed blocks 34 are fixedly connected to the bottom of the adjusting block 32. A rotating shaft 35 is rotatably connected to each of the two sets of fixed blocks 34, allowing the rotating shaft 35 to rotate in its original position. A second clamping plate 36 is fixedly connected to the rotating shaft 35, and the second clamping plate 36 rotates about the rotating shaft 35. Both the first clamping plate 31 and the second clamping plate 36 are L-shaped. The second clamping plate 36, in conjunction with the first clamping plate 31, is clamped at both ends of the sheet metal. After the sheet metal is positioned and calibrated, it is clamped at both ends to prevent displacement of the sheet metal during punching. A first servo motor 37 is installed at the bottom of the adjusting block 32. The output end of the first servo motor 37 is fixedly connected to the rotating shaft 35. After the first servo motor 37 is started, it drives the rotating shaft 35 to rotate, thereby causing the second clamping plate 36 to flip. A set of fixing rods 1 is fixedly connected to a tail plate 38 at the end away from the connecting block 12. A threaded rod 39 is threadedly connected to the tail plate 38. The tail plate 38 is fixed in position, and the threaded rod 39 moves along its own length direction when rotating. The threaded rod 39 is rotatably connected to the adjusting block 32. When the threaded rod 39 rotates and moves, it drives the adjusting block 32 to move synchronously, thereby adapting to sheet metal of different lengths within a certain range.

[0038] Specifically, the aforementioned punching machine also includes a movable assembly 4 mounted on the top of the fixed rod 1. The movable assembly 4 contains a punching mechanism 5, which punches holes in the sheet metal. The movable assembly 4 drives the punching mechanism 5 to move, achieving equidistant punching. The movable assembly 4 includes a guide rail 41 fixedly connected to the top of the fixed rod 1. Multiple sets of sliders 42 are slidably connected to the guide rail 41. A horizontal plate 43 is fixedly connected to the top of each set of sliders 42. The horizontal plate 43 moves smoothly due to the limiting effect of the guide rail 41 and the sliders 42. A movable frame 44 is fixedly connected to the top of each of the two sets of horizontal plates 43. The movable frame 44 is U-shaped and moves synchronously with the two sets of horizontal plates 43. A second servo motor 45 is mounted on a set of horizontal plates 43. The output end of the second servo motor 45 passes through the horizontal plates 43 and is fixedly connected to a gear 46. A rack 47 is provided on one side of the gear 46 and meshes with it. The rack 47 is fixedly connected to the top of the fixed rod 1, and the position of the rack 47 is fixed. After the second servo motor 45 is started, it drives the gear 46 to rotate, thereby moving the horizontal plates 43. At the same time, a grating measurement unit can be installed between the horizontal plates 43 and the fixed rod 1 to accurately determine the position of the moving frame 44 and ensure accurate punching position.

[0039] Furthermore, the aforementioned punching machine also includes a punching mechanism 5, comprising a second push rod motor 51 mounted on the top of the movable frame 44. The output end of the second push rod motor 51 passes through the movable frame 44 and is fixedly connected to a connecting frame 52. The connecting frame 52 is U-shaped and has a lifting plate 53 fixedly connected to its bottom. After the second push rod motor 51 starts, it drives the lifting plate 53 to rise and fall through the connecting frame 52, thereby driving the drill bit 55 closer to the material. A third servo motor 54 is mounted on the top of the lifting plate 53. The output end of the third servo motor 54 passes through the lifting plate 53 and is fixedly connected to the drill bit 55. After the third servo motor 54 starts, it drives the drill bit 55 to rotate, and the drill bit 55 punches holes in the material. Multiple sets of limiting rods 56 are fixedly connected to the top of the lifting plate 53. The limiting rods 56 pass through the movable frame 44 and are fitted with limiting cylinders 57. The limiting cylinders 57 are fixedly connected to the movable frame 44. The limiting action of the limiting rods 56 and the limiting cylinders 57 ensures that the movement of the lifting plate 53 is smooth.

[0040] In this embodiment, the sheet material to be processed is placed on top of multiple sets of guide rollers 23 of the support assembly 2. The rotatable nature of the guide rollers 23 reduces the friction between the sheet material and the support assembly 2, facilitating the pushing of the sheet material from one end of the fixed rod 1 to the processing area. At this time, the sheet material is supported from below by the guide rollers 23. The fixed rod 1, support frame 11, and connecting block 12 serve as the basic structure of the equipment, providing stable support for the entire structure. Rotating the threaded rod 39 in the tail plate 38 causes the threaded rod 39 to rotate. Since the threaded rod 39 is rotatably connected to the adjusting block 32, and the adjusting block 32 slides along the fixed rod 1 via the second limiting block 33, the rotation of the threaded rod 39 will cause the adjusting block 32 to move closer to or further away from the first clamping plate 31 to accommodate sheets of different lengths. After both ends of the sheet material contact the first clamping plate 31 and the second clamping plate 36 respectively, the first servo motor 37 is activated. Its output end drives the rotating shaft 35 to rotate, causing the L-shaped second clamping plate 36 to flip and engage with the first clamping plate 31, clamping the sheet material from both ends and preventing displacement during punching.

[0041] Then, the second servo motor 45 is activated, and its output drives the gear 46 to rotate. The gear 46 meshes with the rack 47 fixed to the top of the fixed rod 1, thereby driving the horizontal plate 43 to move smoothly along the guide rail 41 via the slider 42. The horizontal plate 43 drives the moving frame 44 and the punching mechanism 5 above to move synchronously. Combined with the precise detection of the position of the moving frame 44 by the grating measurement unit, the punching mechanism 5 achieves a fixed displacement above the plate, meeting the punching requirements of equidistant or specific spacing. When the punching mechanism 5 moves to the target position, the second push rod motor 51 is activated, and its output drives the lifting plate 53 to move downward through the connecting frame 52. At the same time, the third servo motor 54 is activated, and its output drives the drill bit 55 to rotate at high speed. After the drill bit 55 contacts the plate, the punching is completed. Then, the second push rod motor 51 drives the lifting plate 53 to reset, and the moving component 4 drives the punching mechanism 5 to the next punching position. The above steps are repeated to complete all punching operations.

[0042] If the punching position overlaps with the initial support position of the guide roller 23, the first push rod motor 27 is activated, and its output end drives the connecting plate 25 to move along the length direction of the fixed rod 1 through the transition plate 26. The connecting plate 25 drives the mounting plate 21 and the guide roller 23 to move synchronously through multiple sets of first limit blocks 24. The first limit blocks 24 ensure that the mounting plate 21 slides smoothly until the guide roller 23 avoids the punching position, so as to avoid interference with the punching mechanism 5 during subsequent punching.

[0043] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
