Description

Technical Field

[0001] This utility model belongs to the technical field of metal circular saw machines, and relates to a feeding mechanism, particularly a follow-up feeding mechanism for metal circular saw machines. Background Technology

[0002] Circular saws can be categorized into metal circular saws and woodworking circular saws based on the products they process. Metal circular saws are primarily used for processing steel materials, such as steel pipes, steel frames, or alloy round bars. When cutting cylindrical workpieces, the circular saw needs to clamp the steel pipe to prevent it from vibrating during processing, which would result in a rough cut surface.

[0003] A search revealed a Chinese patent document disclosing a feeding mechanism for a metal cutting circular saw [Application No.: 202223000035.4; Publication No.: CN 219113034 U]. This feeding mechanism for a metal cutting circular saw relates to the technical field of metal circular saws. It includes a base plate, with hydraulic rods fixedly connected to both ends of the top of the base plate. A U-shaped frame is fixedly connected to the top of each hydraulic rod. Fixed plates are fixedly connected to both sides of the top of the U-shaped frame. Several first feeding mechanisms are sequentially fixedly connected to one side of the U-shaped frame. Each first feeding mechanism includes a first motor, which is fixed to one side of the U-shaped frame. The output end of the first motor passes through the U-shaped frame and is fixedly connected to a rotating shaft. The rotating shaft is located inside the U-shaped frame and rotatably connected to it. Rollers are fixedly connected to the outside of the rotating shaft. This invention automatically feeds the circular metal bar at the top of the roller by turning on the first motor, which drives the rotating shaft to rotate. The rotating shaft then drives the roller to rotate.

[0004] Although this patent can achieve automatic feeding and is simple and convenient to operate, the feeding mechanism of all high-speed metal circular saws in China at present is driven by a servo motor to clamp the bar and feed it to the sawing jaws. When a long bar is continuously cut to about 800 mm in length, the feeding vise only clamps about 300 mm of the front end. When the rear end of the bar is fed forward, it is disengaged from the fixed material support roller on the machine tool. Due to the large weight of the large diameter bar, the rear end will sag and shift, resulting in inaccurate cutting surface. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a follow-up feeding mechanism for metal circular saws. The technical problem this utility model aims to solve is: how to avoid the phenomenon of material sagging and shifting at the rear end, thereby improving the stability of metal materials during cutting.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A follow-up feeding mechanism for a metal circular saw includes a base, a pair of guide rails I fixed on the base, a movable seat slidably connected to the two guide rails I, a pair of guide rails II fixed on the top inclined surface of the movable seat, a positioning frame slidably connected to the two guide rails II, a positioning plate I disposed within the positioning frame, and a hydraulic push rod I fixed on the positioning frame, the output end of the hydraulic push rod I fixedly connected to the positioning plate, a servo motor I fixed on the movable seat, a drive screw rotatably connected to the movable seat between the two guide rails II, the output shaft of the servo motor I and the drive screw being coaxially fixedly connected, the drive screw being threadedly connected to the bottom of the positioning frame, an auxiliary feeding frame I fixed on the base, a material-supporting roller I rotatably connected to the auxiliary feeding frame I, an auxiliary feeding frame II fixed on the movable seat, a material-supporting roller II rotatably connected to the auxiliary feeding frame II, and a positioning frame located at the end of the two guide rails I fixed on the base, the positioning frame having a feeding port and a front-end positioning component.

[0008] The working principle of this utility model is as follows: the material feeding can be assisted by the material support roller 1 and the material support roller 2 to improve the overall feeding effect. Furthermore, through the cooperation of the front positioning component and the positioning plate, the metal material can be limited and fixed in multiple parts. In this way, when the metal circular saw is cutting, the stability of the metal material during cutting can be improved, and the phenomenon of inaccurate cutting surface will not occur.

[0009] The front-end positioning component includes a hydraulic push rod two fixed on a positioning frame, a positioning block one fixedly connected to the output end of the hydraulic push rod two, a guide frame fixed on the positioning frame, a positioning block two disposed inside the guide frame, a hydraulic push rod three fixed on the guide frame, and a positioning block two fixedly connected to the output end of the hydraulic push rod two.

[0010] With the above structure, the positioning block one can be pushed by the hydraulic push rod two, so that the positioning block one presses and fixes the side wall of the metal material from the horizontal direction. The positioning block two can be pushed by the hydraulic push rod three to press and fix the top of the metal material at an angle. The multi-angle fixing and limiting further makes the metal material less prone to shaking and improves the overall stability of cutting and feeding.

[0011] A second servo motor is fixed on the base, and an adjustment screw located between two guide rails is rotatably connected to the base. The output shaft of the second servo motor is coaxially fixedly connected to the adjustment screw, and the adjustment screw is threadedly connected to the moving seat.

[0012] With the above structure, the control screw can be rotated by the second servo motor. After the control screw rotates, it will drive the moving seat to rotate, thereby realizing the movement of the positioning frame. This allows the positioning frame to be fixed in position for metal materials, adapting to metal materials of different lengths and improving the overall operation and feeding effect.

[0013] A support arm located at the bottom of the feeding port is fixed on the base. A guide plate is rotatably connected to the support arm. A rotating seat is rotatably connected to the support arm. A hydraulic push rod II is fixed on the rotating seat. The output end of the hydraulic push rod II is rotatably connected to the guide plate. A servo motor III is fixed on the support arm. The output shaft of the servo motor III is coaxially fixedly connected to the rotating seat.

[0014] With the above structure, the entire hydraulic push rod 2 can be rotated by the servo motor 3, thereby increasing the pushing range of the hydraulic push rod 2. Furthermore, by pushing with the hydraulic push rod 2, the rotation direction of the guide plate can be controlled, which facilitates the guiding, conveying, or collection of the cut metal materials.

[0015] The contact surfaces of the positioning plate one, positioning block one, and positioning block two that come into contact with the metal material are all fixed with a wear-resistant adhesive layer.

[0016] By adopting the above structure, a wear-resistant adhesive layer can be fixed on positioning plate one, positioning block one, and positioning block two to increase the friction force on metal materials and further improve the structural stability during positioning.

[0017] Compared with existing technologies, the follow-up feeding mechanism of this metal circular saw has the following advantages:

[0018] 1. Material feeding is assisted by material support roller one and material support roller two, which improves the overall feeding effect. In addition, the front positioning component and positioning plate work together to limit and fix multiple parts of the metal material. This can improve the stability of the metal material during cutting by the metal circular saw and prevent the phenomenon of inaccurate cut surface.

[0019] 2. The servo motor drives the entire hydraulic push rod two to rotate, thereby increasing the pushing range of the hydraulic push rod two. The pushing of the hydraulic push rod two also controls the rotation direction of the guide plate, making it convenient to guide, transport or collect the cut metal materials.

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] like Figures 1-5 As shown, a follow-up feeding mechanism for a metal circular saw includes a base 1, a pair of guide rails 1-2 fixed on the base 1, a movable seat 3 slidably connected to the two guide rails 1-2, a pair of guide rails 2-4 fixed on the top inclined surface of the movable seat 3, a positioning frame 5 slidably connected to the two guide rails 2-4, a positioning plate 1-6 disposed inside the positioning frame 5, and a hydraulic push rod 1-7 fixed on the positioning frame 5. The output end of the hydraulic push rod 1-7 is fixedly connected to the positioning plate, and a servo motor 1-8 is fixed on the movable seat 3. A servo motor 1-8 located on the two guide rails 2-4 is rotatably connected to the movable seat 3. The drive screw 9 is coaxially fixed to the output shaft of the servo motor 8. The drive screw 9 is threaded to the bottom of the positioning frame 5. An auxiliary feeding frame 10 is fixed on the base 1. A material support roller 11 is rotatably connected to the auxiliary feeding frame 10. An auxiliary feeding frame 2 12 is fixed on the movable seat 3. A material support roller 2 13 is rotatably connected to the auxiliary feeding frame 2 12. A positioning frame 14 located at the end of the two guide slide rails 2 is fixed on the base 1. A feeding port 15 is opened on the positioning frame 14. A front positioning component is provided on the positioning frame 14.

[0028] Material feeding can be assisted by material support roller 11 and material support roller 2 13 to improve the overall feeding effect. Furthermore, through the cooperation of the front positioning component and the positioning plate 6, the metal material can be limited and fixed in multiple parts. This can improve the stability of the metal material during cutting by the metal circular saw and prevent inaccurate cutting surfaces.

[0029] The front-end positioning component includes a hydraulic push rod 26 fixed on the positioning frame 14, a positioning block 17 fixedly connected to the output end of the hydraulic push rod 26, a guide frame 18 fixed on the positioning frame 14, a positioning block 19 disposed inside the guide frame 18, a hydraulic push rod 20 fixed on the guide frame 18, and a positioning block 19 fixedly connected to the output end of the hydraulic push rod 26.

[0030] With the above structure, the positioning block 17 can be pushed by the hydraulic push rod 26, so that the positioning block 17 presses and fixes the side wall of the metal material from the horizontal direction. The positioning block 19 can be pushed by the hydraulic push rod 30 to press and fix the top of the metal material at an angle. The multi-angle fixing limit further makes the metal material less prone to shaking and improves the overall stability of cutting and feeding.

[0031] A servo motor 21 is fixed on the base 1. An adjustment screw 22 located between two guide rails 2 is rotatably connected to the base 1. The output shaft of the servo motor 21 is coaxially fixedly connected to the adjustment screw 22. The adjustment screw 22 is threadedly connected to the moving seat 3.

[0032] With the above structure, the control screw 22 can be rotated by the servo motor 21. After the control screw 22 rotates, it will drive the moving seat 3 to rotate, thereby realizing the movement of the positioning frame 5. This controls the fixed position of the positioning frame 5 on the metal material, adapts to metal materials of different lengths, and improves the overall operation and feeding effect.

[0033] A support arm 23 located at the bottom of the feed port 15 is fixed on the base 1. A guide plate 24 is rotatably connected to the support arm 23. A rotating seat 25 is rotatably connected to the support arm 23. A hydraulic push rod 26 is fixed on the rotating seat 25. The output end of the hydraulic push rod 26 is rotatably connected to the guide plate 24. A servo motor 27 is fixed on the support arm 23. The output shaft of the servo motor 27 is coaxially fixedly connected to the rotating seat 25.

[0034] With the above structure, the entire hydraulic push rod 26 can be rotated by the servo motor 27, thereby increasing the pushing range of the hydraulic push rod 26. Furthermore, the rotation direction of the guide plate 24 can be controlled by pushing the hydraulic push rod 26, which facilitates the guiding, conveying, or collection of the cut metal materials.

[0035] Positioning plate 16, positioning block 17, and positioning block 29 all have a wear-resistant adhesive layer fixed on their contact surfaces with metal materials.

[0036] By adopting the above structure, a wear-resistant adhesive layer can be fixed on positioning plate 16, positioning block 17, and positioning block 29 to increase the friction against metal materials and further improve the structural stability during positioning.

[0037] The working principle of this utility model is as follows: The metal material is conveyed to the material support roller 11 and the material support roller 213 through the material conveying equipment, so that the material is lifted. The lifted material is continuously conveyed to the feeding port 15. At this time, the positioning plate is pushed by the hydraulic push rod 17, so that the positioning plate presses against the middle of the material and limits its movement. Then, the positioning block 17 is pushed by the hydraulic push rod 26, so that the positioning block 17 presses against the side wall of the metal material from the horizontal direction and fixes it. The positioning block 29 is pushed by the hydraulic push rod 320 to press against the top of the metal material at an angle and fix it. The multi-angle fixing and limiting further makes the metal material less prone to shaking, improves the overall cutting and feeding stability, and prevents the phenomenon of inaccurate cutting surface when the metal circular saw is cutting.

[0038] In summary, by using material support roller 11 and material support roller 23 to assist in material feeding and improve the overall feeding effect, and by cooperating with the front-end positioning component and positioning plate 6, the metal material can be limited and fixed in multiple parts. This can improve the stability of the metal material during cutting by the metal circular saw and prevent inaccurate cutting surfaces.
