Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically to an auxiliary feeding mechanism for a shearing machine. Background Technology

[0002] A shearing machine is a machine that uses one blade to reciprocate linearly relative to another blade to shear sheet metal. It utilizes a moving upper blade and a fixed lower blade, with a suitable blade gap, to apply shearing force to metal sheets of various thicknesses, causing the sheet metal to break and separate to the required dimensions. Shearing machines belong to the category of forging and pressing machinery and are primarily used in the metal processing industry.

[0003] However, existing auxiliary feeding mechanisms for shearing machines typically require the conveyor frame to reset after one sheet is fed before the next sheet can be placed on the feeding frame. This results in intermittent feeding of single sheets, which reduces feeding efficiency. To address these issues, the inventors propose an auxiliary feeding mechanism for shearing machines. Utility Model Content

[0004] In order to solve the problem that the auxiliary feeding mechanism of a shearing machine can only feed one sheet intermittently and cannot feed continuously, the purpose of this utility model is to provide an auxiliary feeding mechanism for a shearing machine.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: an auxiliary feeding mechanism for a shearing machine, including a first feeding frame, a first motor installed on one side of the first feeding frame, a rotating shaft fixedly provided at the output end of the first motor, a first bevel gear fixedly sleeved on the outer surface of the rotating shaft, a threaded rod rotatably provided inside the first feeding frame, a second bevel gear fixedly provided on one side of the threaded rod, the first bevel gear meshing with the second bevel gear, a threaded block provided on the outer surface of the threaded rod, a first movable frame fixedly provided on the top surface of the threaded block, a conveying plate provided inside the first movable frame, a first cylinder installed on the top surface of the first movable frame, and the output end of the first cylinder fixedly provided on the top surface of the conveying plate; A second feeding frame is fixedly provided on one side of the first feeding frame. A second moving frame is slidably provided on the top surface of the second feeding frame. A second cylinder is installed on the top surface of the second moving frame. An L-shaped plate is fixedly provided at the output end of the second cylinder. A connecting plate is fixedly connected between the first moving frame and the second moving frame. First, the plate is placed on the top surface of the first feeding frame and the second feeding frame. The second motor is turned on, which causes the bidirectional lead screw to rotate and the support plate to drive the fixed frame to move, so that the limiting roller contacts both sides of the plate, thereby limiting the plate. Then, the first and second cylinders are activated, causing the conveyor plate to contact one side of the sheet metal on the top surface of the first feeding rack, and the L-shaped plate to adhere to one side of the sheet metal on the top surface of the second feeding rack. The first motor is then activated, causing the rotating shaft to drive the first bevel gear to rotate. The first and second bevel gears mesh and transmit power, causing the threaded rod to rotate within the first feeding rack. This causes the threaded block to move the first moving frame towards the shearing machine body, prompting the conveyor plate to push the sheet metal forward. Simultaneously, the connecting plate on one side of the first moving frame pulls the second moving frame, causing the two sheets to move synchronously. The sheet metal on the top surface of the first feeding rack enters the shearing machine body, while the sheet metal on the top surface of the second feeding rack is conveyed to the top surface of the first feeding rack. This enables the feeding of two sheets, improving feeding efficiency.

[0006] Preferably, a slider is fixedly provided on the bottom surface of the second movable frame, the slider is slidably disposed in the second feeding frame, a slide groove is provided in the second feeding frame, a slide rod is fixedly provided in the slide groove, and the slider is slidably disposed in the slide groove.

[0007] Preferably, a fixed frame is provided above both the first and second feeding frames, and a limiting roller is rotatably provided inside the fixed frame. A groove is provided inside both the first and second feeding frames. A support plate is fixedly provided on one side of the fixed frame and is slidably disposed in the groove. A second motor is installed on one side of both the first and second feeding frames. A bidirectional lead screw is fixedly provided at the output end of the second motor. The support plate is threaded onto the outer surface of the bidirectional lead screw. A guide rod is rotatably provided inside both the first and second feeding frames, and an auxiliary roller is fixedly provided on the outer surface of the guide rod.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The first moving frame moves towards the shearing machine body, causing the conveying plate to push the plate to move. At the same time, the connecting plate on one side of the first moving frame can pull the second moving frame to move, thereby making the two plates move synchronously. The plate on the top surface of the first feeding frame enters the shearing machine body, and the plate on the top surface of the second feeding frame is conveyed to the top surface of the first feeding frame, thus realizing the feeding of two plates and improving the feeding efficiency. 2. By turning on the second motor, the bidirectional lead screw rotates, causing the support plate to move the fixed frame, which in turn causes the limiting rollers to contact both sides of the plate, thereby limiting the plate and preventing deviation during the conveying process.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Example: Figure 1-6As shown, this utility model provides an auxiliary feeding mechanism for a shearing machine, including a first feeding frame 1. A first motor 2 is installed on one side of the first feeding frame 1. A rotating shaft 21 is fixedly installed at the output end of the first motor 2. A first bevel gear 22 is fixedly sleeved on the outer surface of the rotating shaft 21. A threaded rod 23 is rotatably installed inside the first feeding frame 1. A second bevel gear 24 is fixedly installed on one side of the threaded rod 23. The first bevel gear 22 and the second bevel gear 24 mesh with each other. A threaded block 25 is provided on the threaded surface of the threaded rod 23. A first moving frame 26 is fixedly installed on the top surface of the threaded block 25. A conveying plate 28 is installed inside the first moving frame 26. A first cylinder 27 is installed on the top surface of the first moving frame 26. The output end of the first cylinder 27 is fixedly installed on the top surface of the conveying plate 28. A shearing machine body 5 is fixedly installed on one side of the first feeding frame 1. (The sheet metal is pushed by the conveying plate 28 and transported to the shearing area of ​​the shearing machine body 5. By opening the shearing machine body 5, the sheet metal can be cut.) A second feeding rack 3 is fixedly installed on one side of the first feeding rack 1. A second movable rack 32 is slidably installed on the top surface of the second feeding rack 3. A second cylinder 34 is installed on the top surface of the second movable rack 32. An L-shaped plate 35 is fixedly installed at the output end of the second cylinder 34. A connecting plate 36 is fixedly connected between the first movable rack 26 and the second movable rack 32. By placing the plate on the top surface of the first feeding rack 1 and the second feeding rack 3, and then activating the first cylinder 27 and the second cylinder 34, the conveying plate 28 contacts one side of the plate on the top surface of the first feeding rack 1, and the L-shaped plate 35 adheres to one side of the plate on the top surface of the second feeding rack 3. Then, the first motor 2 is activated, and the conveying plate 28 contacts one side of the plate on the top surface of the first feeding rack 1. The L-shaped plate 35 adheres to one side of the plate on the top surface of the second feeding rack 3. Then, the first motor 2 is activated, and the conveying plate 28 is activated from the top surface of the second feeding rack 3. The rotating shaft 21 drives the first bevel gear 22 to rotate, and the first bevel gear 22 meshes with the second bevel gear 24 to drive the threaded rod 23 to rotate inside the first feeding frame 1. This causes the threaded block 25 to drive the first moving frame 26 to move towards the shearing machine body 5, which in turn causes the conveying plate 28 to push the plate to move. At the same time, the connecting plate 36 on one side of the first moving frame 26 can pull the second moving frame 32 to move, thereby making the two plates move synchronously. The plate on the top surface of the first feeding frame 1 enters the shearing machine body 5, and the plate on the top surface of the second feeding frame 3 is conveyed to the top surface of the first feeding frame 1, thus realizing the feeding of two plates and improving the feeding efficiency.

[0014] The bottom surface of the second movable frame 32 is fixedly provided with a slider 33, which is slidably disposed in the second feeding frame 3. A slide groove 301 is provided in the second feeding frame 3, and a slide rod 31 is fixedly disposed in the slide groove 301. The slider 33 is slidably disposed in the slide groove 301.

[0015] By adopting the above technical solution, when the second movable frame 32 slides, it drives the slider 33 to slide on the outer surface of the slide rod 31, thereby assisting the second movable frame 32 to slide.

[0016] A fixed frame 43 is provided above the first feeding frame 1 and the second feeding frame 3 facing each other. A limiting roller 44 is rotatably provided inside the fixed frame 43. A groove 302 is provided inside the first feeding frame 1 and the second feeding frame 3. A support plate 42 is fixedly provided on one side of the fixed frame 43 and slides in the groove 302. A second motor 4 is installed on one side of the first feeding frame 1 and the second feeding frame 3. A bidirectional lead screw 41 is fixedly provided at the output end of the second motor 4. The support plate 42 is threaded onto the outer surface of the bidirectional lead screw 41. A guide rod 11 is rotatably provided inside the first feeding frame 1 and the second feeding frame 3. An auxiliary roller 12 is fixedly provided on the outer surface of the guide rod 11.

[0017] By adopting the above technical solution, the second motor 4 is turned on, thereby causing the bidirectional lead screw 41 to rotate and the support plate 42 to drive the fixed frame 43 to move, causing the limiting roller 44 to contact both sides of the plate, thereby limiting the plate and preventing deviation during the conveying process. Through the guide rod 11 and the auxiliary roller 12, the friction between the plate and the first feeding frame 1 and the second feeding frame 3 is reduced during the conveying of the plate.

[0018] Working principle: First, place the board on the top surface of the first feeding rack 1 and the second feeding rack 3, turn on the second motor 4, so that the bidirectional lead screw 41 rotates and the support plate 42 drives the fixed frame 43 to move, so that the limiting roller 44 contacts both sides of the board, thereby limiting the board. Then, the first cylinder 27 and the second cylinder 34 are activated, causing the conveying plate 28 to contact the plate side on the top surface of the first feeding rack 1, and the L-shaped plate 35 to adhere to the plate side on the top surface of the second feeding rack 3. Then, the first motor 2 is activated, causing the rotating shaft 21 to drive the first bevel gear 22 to rotate. The first bevel gear 22 meshes with the second bevel gear 24, thereby causing the threaded rod 23 to rotate inside the first feeding rack 1. This causes the threaded block 25 to drive the first moving frame 26 to move towards the shearing machine body 5, prompting the conveying plate 28 to push the plate to move. At the same time, the connecting plate 36 on one side of the first moving frame 26 can pull the second moving frame 32 to move, thereby causing the two plates to move synchronously. The plate on the top surface of the first feeding rack 1 enters the shearing machine body 5, and the plate on the top surface of the second feeding rack 3 is conveyed to the top surface of the first feeding rack 1, thus realizing the feeding of two plates and improving the feeding efficiency.
