Abstract
Description
Technical Field
[0001] This utility model relates to the field of flying shear equipment, specifically to a precision feeding flying shear for sheet metal. Background Technology
[0002] Flying shears are used to cut moving sheet metal. They offer good cutting continuity and high efficiency, and are widely used in various industrial production processes.
[0003] Patent document CN216858415U discloses a sheet metal flying shear, which includes a base frame, a cutting assembly, and a drive assembly. The cutting assembly is used to cut the sheet metal and includes an upper blade and a lower blade, which are tangent to each other in the vertical direction. The sheet metal is located between the upper and lower blades. The drive assembly is used to drive the upper and lower blades to perform circular motion, and both the upper and lower blades move back and forth in the horizontal direction along the conveying direction of the sheet metal. Furthermore, a baffle limits the sheared sheet metal, thereby improving the stability of the shearing and conveying of the sheet metal. However, this solution has the following problems that need to be addressed:
[0004] 1. During the feeding process, the boards may tilt or bend due to lack of limiters or machine vibration, resulting in the length and shape of the boards after being cut by the flying shear not matching expectations.
[0005] 2. Although the flying shear has a baffle to limit the cutting process, there is still a certain space between the board and the baffle. This causes the upper and lower blades to stick together, making it easy for the board to shift or tilt. As a result, the accuracy of the flying shear is reduced.
[0006] 3. When the upper and lower blades cut the sheet metal, they will produce some metal shavings. These shavings will adhere to the upper and lower blades and affect the cutting accuracy.
[0007] Based on this, this utility model designs a precision feeding flying shear for sheet metal to solve the above problems. Utility Model Content
[0008] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a precision feeding flying shear for sheet metal.
[0009] To achieve the above objectives, this utility model provides the following technical solution:
[0010] A precision-feeding flying shear for sheet metal includes a conveyor and a frame. A cutting mechanism is symmetrically installed on the upper and lower sides inside the frame. A synchronous cleaning and pressing mechanism is installed at the cutting end of each cutting mechanism. The synchronous cleaning and pressing mechanism is used to fix the sheet metal before cutting and to clean the cutting end of the cutting mechanism after cutting. Steel plate limiting mechanisms are symmetrically arranged on both sides of the conveyor. Each steel plate limiting mechanism includes a horizontal limiting component and a vertical limiting component. A horizontal limiting component is located on one side of the conveyor, and a vertical limiting component is installed on top of the horizontal limiting component.
[0011] Furthermore, the horizontal limiting component includes a support frame, a push cylinder, an L-shaped plate, and a side limiting module; a support frame is provided on one side of the conveyor, an L-shaped plate is fixedly connected to the support frame, a push cylinder is fixedly connected to the end of the L-shaped plate away from the conveyor, and a side limiting module is installed on the other end of the L-shaped plate.
[0012] Furthermore, the side limiting module includes a first slide rail, a first slider, an inclined block, a first bracket, and a first roller; the other end of the L-shaped plate is fixedly connected to the first slide rail, the first slide rail is slidably connected to the first slider, and the output shaft of the push cylinder is fixedly connected to the first slider. An inclined block is fixedly connected to the first slider. The end of the first bracket away from the conveyor is fixedly connected to the end of the inclined block near the conveyor. The other end of the first bracket is rotatably connected to the first roller. The first roller moves toward the steel plate until it contacts one end of the plate, thus limiting the movement of the plate.
[0013] Furthermore, the vertical limiting component includes a second slide rail, a second slider, a transmission rod, a connecting rod, a driven rod, a second bracket, a second roller, and a crossbar; the top of the L-shaped plate is fixedly connected to the crossbar, the second slide rail is fixedly connected to the inclined surface of the inclined block, the upper limit of the second slide rail is slidably connected to the second slider, the second slider is fixedly connected to the lower end of the transmission rod, and the middle part of the transmission rod is slidably connected to the crossbar, the upper end of the transmission rod is fixedly connected to one end of the connecting rod, the other end of the connecting rod is fixedly connected to the upper end of the driven rod, and the middle part of the driven rod is slidably connected to the crossbar, the upper end of the second bracket is fixedly connected to the lower end of the driven rod, and the other end of the second bracket is rotatably connected to the second roller, the second roller moves downward until it contacts the upper end of the plate, thus limiting the movement of the plate.
[0014] Furthermore, the synchronous cleaning and pressing mechanism includes a pressure plate, a moving block, a fixed cylinder, and a spring; multiple fixed cylinders are fixedly connected to the blade holder of the cutting mechanism along its length direction, a moving block is slidably connected to the inner wall of the fixed cylinder, a spring is fixedly connected between the fixed cylinder and the moving block, a pressure plate is fixedly connected to the lower end of the moving block, and the side of the pressure plate is slidably connected to the side of the blade of the cutting mechanism.
[0015] Furthermore, the conveyor is either a belt conveyor or a roller conveyor.
[0016] Furthermore, the pressure plate is made of rubber.
[0017] Furthermore, the fixed cylinders are arranged at equal intervals along the length direction of the cutter holder of the cutting mechanism.
[0018] Compared with the prior art, the advantages of this utility model are as follows: 1. By using the combined action of the horizontal limiting component, the vertical limiting component and the conveyor, the material is limited when it is fed into the plate, so that the length and shape of the plate are more accurate when the flying shear is cutting; and by using the synchronous cleaning pressing mechanism to fix the plate before the cutting mechanism cuts and to clean the cutting mechanism after cutting, the flying shear is more accurate when cutting.
[0019] 2. By using the first roller to limit the plate in the horizontal direction and the second roller to limit the plate in the vertical direction, the plate is restricted to move forward in the middle position of the conveyor, making the length and shape of the plate more accurate when the flying shear is cutting.
[0020] 3. Before the upper and lower blades of the cutting assembly cut the sheet material, the pressure plate first contacts the sheet material, which restricts the sheet material. When the sheet material is cut, it will not stick to the upper and lower blades of the cutting assembly, resulting in higher precision when the upper and lower blades of the cutting assembly cut the sheet material. After the upper and lower blades of the cutting assembly cut the sheet material, the upper and lower blades of the cutting assembly rub against the pressure plate, which has the function of cleaning the upper and lower blades of the cutting assembly, ensuring the precision of the next cut and extending the service life of the upper and lower blades of the cutting assembly.
[0021] 4. The pressure plate is made of rubber, which makes it lightweight and increases the friction with the upper and lower blades of the cutting component, resulting in better cleaning. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0033] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.
[0034] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-7 A precision feeding flying shear for sheet metal includes a conveyor 1 and a frame 2, with the conveyor 1 located at the rear of the frame 2;
[0035] The upper and lower sides of the frame 2 are symmetrically installed with cutting mechanisms 3. A synchronous cleaning and pressing mechanism 5 is installed at the cutting end of the cutting mechanism 3. The synchronous cleaning and pressing mechanism 5 is used to fix the plate before the cutting mechanism 3 cuts and to clean the cutting end of the cutting mechanism 3 after cutting.
[0036] Steel plate limiting mechanisms 4 are symmetrically arranged on both sides of the conveyor 1. The steel plate limiting mechanism 4 includes a horizontal limiting component 41 and a vertical limiting component 42. A horizontal limiting component 41 is arranged on one side of the conveyor 1, and a vertical limiting component 42 is installed on the horizontal limiting component 41.
[0037] In this invention, after unwinding and straightening, the sheet material is transferred to the conveyor 1. As the conveyor 1 moves forward, the sheet material passes between the two cutting mechanisms 3 and is cut by the two cutting mechanisms 3 when passing the frame 2. When the sheet material moves on the conveyor 1, the horizontal limiting component 41 moves horizontally towards the sheet material until it contacts the side surface of the sheet material. At the same time, the vertical limiting component 42 moves vertically downward until it presses the sheet material down onto the conveyor 1. Thus, under the combined action of the horizontal limiting component 41, the vertical limiting component 42, and the conveyor 1, the sheet material is restricted to the middle position of the conveyor 1 and moves forward. When the sheet material is cut by the cutting mechanism 3, the synchronous cleaning pressing mechanism 5 moves synchronously circumferentially with the cutting end of the cutting mechanism 3. Before the cutting mechanism 3 cuts, the synchronous cleaning pressing mechanism 5 holds the sheet material from both the top and bottom. After cutting, the synchronous cleaning pressing mechanism 5 releases the sheet material and cleans the cutting end of the cutting mechanism 3.
[0038] In this invention, the horizontal limiting component 41, the vertical limiting component 42 and the conveyor 1 work together to limit the feeding of the board, making the length and shape of the board more precise when the flying shear is cutting; and the synchronous cleaning pressing mechanism 5 fixes the board before the cutting mechanism 3 cuts and cleans the cutting mechanism 3 after cutting, making the flying shear more precise when cutting.
[0039] The horizontal limiting component 41 includes a support frame 411, a push cylinder 412, an L-shaped plate 413, a first slide rail 414, a first slider 415, an inclined block 416, a first bracket 417, and a first roller 418. A support frame 411 is provided on one side of the conveyor 1. An L-shaped plate 413 is fixedly connected to the support frame 411. A push cylinder 412 is fixedly connected to the end of the L-shaped plate 413 away from the conveyor 1. A first slide rail 414 is fixedly connected to the other end of the L-shaped plate 413. The first slide rail 414 is slidably connected to the first slider 415 at its upper limit. The output shaft of the push cylinder 412 is fixedly connected to the first slider 415. An inclined block 416 is fixedly connected to the first slider 415. The end of the first bracket 417 away from the conveyor 1 is fixedly connected to the end of the inclined block 416 near the conveyor 1. The other end of the first bracket 417 is rotatably connected to the first roller 418. The first roller 418 moves towards the steel plate until it contacts one end of the plate, thus limiting the movement of the plate.
[0040] The vertical limiting assembly 42 includes a second slide rail 421, a second slider 422, a transmission rod 423, a connecting rod 424, a driven rod 425, a second bracket 426, a second roller 427, and a crossbar 428. A crossbar 428 is fixedly connected to the top of the L-shaped plate 413, and a second slide rail 421 is fixedly connected to the inclined surface of the inclined block 416. A second slider 422 is slidably connected to the upper limit of the second slide rail 421. The second slider 422 is fixedly connected to the lower end of the transmission rod 423, and the transmission... The middle part of the moving rod 423 is slidably connected to the cross rod 428. The upper end of the transmission rod 423 is fixedly connected to one end of the connecting rod 424. The other end of the connecting rod 424 is fixedly connected to the upper end of the driven rod 425. The middle part of the driven rod 425 is slidably connected to the cross rod 428. The upper end of the second bracket 426 is fixedly connected to the lower end of the driven rod 425. The other end of the second bracket 426 is rotatably connected to the second roller 427. The second roller 427 moves downward until it contacts the upper end of the plate, which has the function of restricting the movement of the plate.
[0041] In this invention, when the sheet material moves on the conveyor 1, the push cylinder 412 is activated to push the first slider 415 horizontally along the first slide rail 414 towards the sheet material. The first slider 415 drives the inclined block 416, the first support 417, and the first roller 418 to move horizontally towards the sheet material simultaneously until the two first rollers 418 abut against the two ends of the sheet material, thus limiting the sheet material to the middle position of the conveyor 1. At the same time, the movement of the inclined block 416 drives the second slide rail 421 to move horizontally towards the sheet material, causing the second slider 422 to move along the second slide rail 421. The second slider 422 drives the transmission rod 423, the connecting rod 424, the driven rod 425, the second support 426, and the second roller 427 to move downward in the vertical direction until the second roller 427 presses the sheet material onto the conveyor 1, thus limiting the sheet material in the vertical direction.
[0042] In this invention, the first roller 418 limits the plate in the horizontal direction and the second roller 427 limits the plate in the vertical direction, restricting the plate to move forward in the middle position of the conveyor 1, so that the length and shape of the plate are more accurate when the flying shear is cutting.
[0043] The cutting mechanism 3 can adopt the cutting component and driving component of a sheet metal flying shear disclosed in CN216858415U.
[0044] The synchronous cleaning and pressing mechanism 5 includes a pressure plate 51, a moving block 52, a fixed cylinder 53, and a spring 54; multiple fixed cylinders 53 are fixedly connected to the blade holder of the cutting mechanism 3 along its length direction, a moving block 52 is slidably connected to the inner wall of the fixed cylinder 53, a spring 54 is fixedly connected between the fixed cylinder 53 and the moving block 52, a pressure plate 51 is fixedly connected to the lower end of the moving block 52, and the side of the pressure plate 51 is slidably connected to the side of the blade of the cutting mechanism 3.
[0045] In this invention, the pressure plate 51, the moving block 52, the fixed cylinder 53, and the spring 54 follow the upper and lower blade holders of the cutting assembly and the upper and lower blades of the cutting assembly in a circular motion within the frame 2. Before the upper and lower blades of the cutting assembly cut the plate, the two pressure plates 51 approach the plate from the upper and lower sides, and the plate is limited by the action of the spring 54. The upper and lower blades of the cutting assembly continue to move until they cooperate to cut the plate. Subsequently, the upper and lower blades of the cutting assembly reset, and the upper and lower blades of the cutting assembly are relatively displaced from the pressure plate 51. The metal debris on the sides of the upper and lower blades of the cutting assembly is then removed by friction through the side of the pressure plate 51. The fixed cylinders 53 are arranged at equal intervals along the length direction of the blade holder of the cutting mechanism 3.
[0046] In this invention, before the upper and lower blades of the cutting assembly cut the sheet material, the pressure plate 51 first contacts the sheet material, which restricts the sheet material. When the sheet material is cut, it will not stick to the upper and lower blades of the cutting assembly, resulting in higher precision when the upper and lower blades of the cutting assembly cut the sheet material. After the upper and lower blades of the cutting assembly cut the sheet material, the upper and lower blades of the cutting assembly rub against the pressure plate 51, which cleans the upper and lower blades of the cutting assembly, ensuring the precision of the next cut and extending the service life of the upper and lower blades of the cutting assembly.
[0047] The conveyor 1 can be a belt conveyor or a roller conveyor, etc.
[0048] The pressure plate 51 is made of rubber, which makes it lightweight and increases the friction with the upper and lower blades of the cutting assembly, resulting in better cleaning.
[0049] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
