Description

Technical Field

[0001] This utility model relates to the field of metal shearing technology, specifically a metal shearing machine with positioning function. Background Technology

[0002] With the continuous development of society, the metal processing industry has achieved vigorous development. When processing metal, it is necessary to cut the metal according to the corresponding data for subsequent use. Metal shearing machines are commonly used cutting tools. Traditional shearing machines are not convenient for moving and cutting metal products due to their fixing method. When the cutting size exceeds the fixed device, it cannot be effectively fixed, making them extremely cumbersome to use, affecting the cutting progress and reducing work efficiency.

[0003] According to the public announcement of a metal shearing machine with convenient metal fixing function (Announcement No.: CN216938675U), the above application effectively solves the problem that the fixing method of existing metal cutting machines on the market is inconvenient for moving and cutting metal products, and that metal with a cutting size exceeding the fixing device cannot be effectively fixed. It is a metal shearing machine that facilitates metal fixing.

[0004] However, in actual use, the above-mentioned equipment only controls the metal to be processed in one direction by rotating the roller to hold the fixed frame, which cannot meet the needs of metal shearing. In addition, the equipment only controls the metal by force in one direction and does not have a locking mechanism, so it requires manual control for a long time, which is time-consuming and labor-intensive. In view of this, we propose a metal shearing machine with positioning function. Utility Model Content

[0005] The purpose of this invention is to provide a metal shearing machine with positioning function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A metal shearing machine with positioning function includes a shearing base, a support leg fixedly connected to the lower surface of the shearing base, and a positioning mechanism provided on the upper surface of the shearing base, the positioning mechanism comprising:

[0007] The mounting slot is located on the upper surface of the shear seat. A telescopic rod is fixedly connected to the bottom surface of the mounting slot. A compression spring is sleeved on the outer surface of the telescopic rod. A connecting plate is fixedly connected to the end of the telescopic rod away from the bottom surface of the mounting slot. A mounting bracket is fixedly connected to the upper surface of the connecting plate.

[0008] The equipment slot is located on the lower surface of the mounting frame. A telescopic sleeve is fixedly connected to the bottom surface of the equipment slot. A telescopic spring is fitted onto the outer surface of the telescopic sleeve. A protective sleeve is slidably connected to the inner side wall of the equipment slot. A positioning plate is fixedly connected to the end of the telescopic sleeve away from the mounting frame.

[0009] Preferably, the number of positioning plates is set to multiple sets, and the multiple sets of positioning plates are distributed in a linear array at the end of the telescopic sleeve away from the mounting frame, and each pair of positioning plates is hinged by a movable shaft.

[0010] Preferably, the upper surface of the shearing seat is provided with an auxiliary mechanism, the auxiliary mechanism including a limiting groove, the limiting groove being formed on the upper surface of the shearing seat, a motor being fixedly connected to the lower surface of the shearing seat, a rotating gear being fixedly connected to the outer surface of the output end of the motor, and the bottom surface of the rotating gear abutting against the upper surface of the limiting groove.

[0011] Preferably, a movable toothed plate meshes with the outer surface of the rotating gear, a cover plate is fixedly connected to the side wall of the limiting groove, a clamping seat is fixedly connected to the upper surface of the movable toothed plate, and a rubber strip is fixedly connected to the side of the clamping seat away from the mounting groove.

[0012] Preferably, the shear seat is concave in shape, the mounting groove is located at the high position of the shear seat, and the limiting groove is located at the low position of the shear seat.

[0013] Preferably, a fixing plate is fixedly connected between two adjacent sets of support legs, and a reinforcing rod is fixedly connected to the side of the fixing plate away from both ends of the shear seat.

[0014] Preferably, the number of mounting brackets is set to multiple sets, and the multiple sets of mounting brackets are distributed in a linear array on the upper surface of the connecting plate. The bottom surface of the equipment slot on the lower surface of the mounting bracket located at the center is fixedly connected to a telescopic cylinder, and the movable end of the telescopic cylinder is fixedly connected to a shearing blade.

[0015] Compared with the prior art, this utility model provides a metal shearing machine with positioning function, which has the following beneficial effects:

[0016] 1. This metal shearing machine with positioning function, through the setting of a positioning mechanism, and in conjunction with the telescopic rod and compression spring support plate and mounting frame in the mounting slot, enables the mounting frame to have a certain tensile capacity, accommodating metal processing of larger shapes. The telescopic sleeve and telescopic spring in the equipment slot under the mounting frame further provide vertical elastic expansion space for the positioning plate, guided and protected by a protective sleeve. Multiple sets of linearly arrayed positioning plates are connected by hinged movable shafts, giving the entire positioning contact surface excellent flexibility and adaptability. This allows it to effectively adapt to the surface contours of metal workpieces of different shapes and sizes, providing multi-directional elastic buffering while applying positioning pressure, significantly reducing the risk of indentation or scratches on the workpiece surface, and absorbing vibrations or minor displacements that may occur during the shearing process, thereby greatly improving positioning stability and workpiece protection.

[0017] 2. This metal shearing machine with positioning function, through an auxiliary mechanism and a motor-driven rotating gear, moves a moving toothed plate and clamping seat along a predetermined trajectory within a limiting groove via a gear and rack meshing principle. A cover plate restricts the toothed plate's movement direction and provides protection, while rubber strips on the clamping seat provide friction. Combined with the concave design of the shearing seat and the high-low groove layout, this facilitates further control of the metal material and provides a precisely controllable lateral clamping function. This mechanism can work in conjunction with the positioning mechanism, applying controllable clamping or pushing force from the side based on vertical positioning, effectively preventing lateral slippage or tilting of the workpiece during the shearing process. This not only significantly improves the overall stability of the workpiece at the shearing station, reduces operational difficulty and the need for manual intervention, but also protects the workpiece's sides through the rubber strips, improving shearing accuracy and operational efficiency.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a metal shearing machine with positioning function, including a shearing seat 1, a support leg 11 fixedly connected to the lower surface of the shearing seat 1, and a positioning mechanism 2 provided on the upper surface of the shearing seat 1. The positioning mechanism 2 includes: a mounting groove 21, a telescopic rod 22, a compression spring 23, a connecting plate 24, a mounting bracket 25, an equipment groove 26, a telescopic sleeve 27, a telescopic spring 28, a protective sleeve 29, a positioning plate 210, and a movable shaft 211.

[0024] In one embodiment of this utility model, a mounting groove 21 is formed on the upper surface of the shearing seat 1. A telescopic rod 22 is fixedly connected to the bottom surface of the mounting groove 21. A compression spring 23 is sleeved on the outer surface of the telescopic rod 22. A connecting plate 24 is fixedly connected to the end of the telescopic rod 22 away from the bottom surface of the mounting groove 21. By setting the mounting groove 21, the telescopic rod 22, the compression spring 23, and the connecting plate 24, a movable threshold range can be provided for the mounting frame 25. When facing large metal shearing processing, the tension and compression spring 23 can cause the fixed-shape mounting frame 25 to move upward, thus providing a larger processing space. The mounting frame 25 is fixedly connected to the upper surface of the connecting plate 24. An equipment groove 26 is formed on the lower surface of the mounting frame 25. A telescopic sleeve 27 is fixedly connected to the bottom surface of the equipment groove 26. A telescopic spring 28 is sleeved on the outer surface of the telescopic sleeve 27. A protective sleeve 29 is slidably connected to the inner side wall of the equipment groove 26. The equipment groove 26 is located below the mounting frame 25. The telescopic sleeve 27 and telescopic spring 28 inside further provide vertical elastic telescopic space for the positioning plate 210, and are guided and protected by the protective sleeve 29. The positioning plate 210 is fixedly connected to the end of the telescopic sleeve 27 away from the mounting bracket 25. There are multiple sets of positioning plates 210, and the multiple sets of positioning plates 210 are distributed in a linear array at the end of the telescopic sleeve 27 away from the mounting bracket 25. Each pair of positioning plates 210 is hinged by a movable shaft 211. The multiple sets of linearly distributed positioning plates 210 are hinged together by the movable shaft 211, so that the entire positioning contact surface has excellent flexibility and adaptability, which can effectively adapt to the surface contour of metal workpieces of different shapes and sizes. While applying positioning pressure, it provides multi-directional elastic buffering, significantly reducing the risk of indentation or scratches on the workpiece surface, and absorbing the vibration or small displacement that may be generated by the workpiece during shearing, thereby greatly improving the stability of positioning and the protection of the workpiece.

[0025] In addition, an auxiliary mechanism 3 is provided on the upper surface of the shearing seat 1. The auxiliary mechanism 3 includes a limiting groove 31, which is formed on the upper surface of the shearing seat 1. A motor 32 is fixedly connected to the lower surface of the shearing seat 1. A rotating gear 33 is fixedly connected to the outer surface of the output end of the motor 32. The bottom surface of the rotating gear 33 abuts against the upper surface of the limiting groove 31. A movable toothed plate 34 meshes with the outer surface of the rotating gear 33. The rotating gear 33 is driven to rotate by the motor 32, which in turn drives the movable toothed plate 34 to move, thus enabling the moving toothed plate 34 to move. The clamping seat 35, which is fixedly connected to the upper surface of the moving toothed plate 34, clamps the metal parts laterally and synchronously. The side wall of the limiting groove 31 is fixedly connected to a cover plate 36 to prevent the debris generated during metal shearing from entering the interior of the limiting groove 31, thus avoiding any impact on the auxiliary mechanism 3. The upper surface of the moving toothed plate 34 is fixedly connected to a clamping seat 35. A rubber strip is fixedly connected to the side of the clamping seat 35 away from the mounting groove 21. The rubber strip on the clamping seat 35 provides friction, protects the side of the workpiece, and improves shearing accuracy and operating efficiency.

[0026] In this embodiment of the utility model, the shearing seat 1 is shaped as a "concave" shape. The mounting groove 21 is opened at the high position of the shearing seat 1, and the limiting groove 31 is opened at the low position of the shearing seat 1. This can prevent the mounting frame 25 from obstructing the metal parts being processed, allowing them to be sheared more smoothly. A fixing plate is fixedly connected between two adjacent sets of support legs 11. A reinforcing rod 12 is fixedly connected to the side of the fixing plate away from both ends of the shearing seat 1. The setting of the fixing plate and the reinforcing rod 12 can strengthen the rigidity of the entire equipment, thereby ensuring the service life of the equipment. There are multiple sets of mounting frames 25, and the multiple sets of mounting frames 25 are distributed in a linear array on the upper surface of the connecting plate 24. The bottom surface of the equipment groove 26 on the lower surface of the mounting frame 25 located in the center is fixedly connected to the telescopic cylinder 4. The movable end of the telescopic cylinder 4 is fixedly connected to the shearing blade 41. The telescopic cylinder 4 pushes the shearing blade 41 to shear the metal parts, achieving the effect of width redundancy.

[0027] In this utility model, when the workpiece is placed on the upper surface of the shearing seat 1, the positioning plate 210 in the positioning mechanism 2 can adaptively contact and initially position the side of the workpiece under the action of the telescopic sleeve 27 and the telescopic spring 28. The multiple sets of hinged positioning plates 210 can flexibly adjust the angle. At the same time, the motor 32 in the auxiliary mechanism 3 drives the rotating gear 33 to rotate, which drives the moving toothed plate 34 and the clamping seat 35 that mesh with it to move. With the help of the rubber strip, the workpiece is clamped from the other side, and the workpiece is reliably fixed. Finally, the telescopic cylinder 4 located below the central mounting frame 25 drives the shearing blade 41 to move downward to perform the shearing operation on the positioned and clamped workpiece.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
