Multiple equally spaced conveying rollers are rotatably connected to the U-shaped table along its length via bearings. Adjustable spacing limiting plates are provided on both sides of the inlet end of the U-shaped table. A U-shaped frame is provided on the upper surface of the outlet end of the U-shaped table. A vertically movable pressure plate is provided inside the U-shaped frame. L-shaped plates are provided on both sides of the U-shaped frame. A one-way screw is rotatably connected between two L-shaped plates via bearings. A motor is mounted on one of the L-shaped plates. The shaft of the motor is connected to the one-way screw. A second threaded block is threaded onto the one-way screw. An L-shaped seat is provided at the bottom of the second threaded block. A cutting motor is mounted on the L-shaped seat. A cutting blade is connected to the shaft of the cutting motor, and the shaft of the cutting motor passes through the vertical section of the L-shaped seat and is rotatably connected to it via bearings.

[0006] Preferably, a second slide bar is provided between the two L-shaped plates below the unidirectional lead screw, and the horizontal section of the L-shaped seat is provided with a sliding hole that is slidably connected to the second slide bar.

[0007] Preferably, the upper two sides of the U-shaped platform are rotatably connected to a bidirectional lead screw via bearing seats. Each side of the bidirectional lead screw is provided with a first slide rod distributed parallel to it. Both ends of the first slide rod are fixedly connected to the upper surface of the U-shaped platform via fixed seats. The middle part of the upper surface of the limiting plate is provided with a first threaded block that is threadedly connected to the bidirectional lead screw. Both sides of the upper surface of the limiting plate are provided with sliders that are slidably connected to the first slide rods.

[0008] Preferably, one end of the bidirectional lead screw extends to the outside of the bearing seat and is provided with a crank handle, and there is a gap between the bottom of the limiting plate and the upper surface of the conveying roller.

[0009] Preferably, the length direction of the U-shaped platform is perpendicular to the length direction of the belt conveyor, the length direction of the limiting plate is perpendicular to the length direction of the conveying roller, and the length direction of the unidirectional lead screw is parallel to the length direction of the conveying roller.

[0010] Preferably, a cylinder is mounted on the middle part of the upper surface of the U-shaped frame via a fixing bracket. The piston rod of the cylinder passes through the U-shaped frame and is fixedly connected to the middle part of the upper surface of the pressure plate. Limiting rods are provided at the four corners of the upper surface of the pressure plate. The upper surface of the U-shaped frame is provided with four through holes that correspond one-to-one with the limiting rods. The through holes are slidably connected to the limiting rods.

[0011] Preferably, the plurality of conveying rollers are connected by a chain and sprocket assembly.

[0012] The automotive sheet metal shearing device of this utility model has the following advantages:

[0013] 1. This utility model utilizes the cooperation between a belt conveyor and a U-shaped table to ensure that the cut automotive sheet metal falls directly onto the belt conveyor and is transported down, avoiding the accumulation of cut automotive sheet metal that could cause damage. At the same time, the conveyor rollers continue to transport the automotive sheet metal to the cutting blade for cutting. This process is repeated continuously, which can cut automotive sheet metal continuously, greatly improving work efficiency and achieving a high degree of automation, thus saving a lot of manpower.

[0014] 2. By rotating the crank handle, the bidirectional lead screw can be rotated. Under the action of the first threaded block, the first sliding rod, and the slider, the two limiting plates can be moved away from or closer to each other, thereby adjusting the distance between the two limiting plates. This ensures that the automotive sheet moving on the conveying roller is positioned between the two limiting plates, providing a good limiting effect on the automotive sheet and effectively preventing the automotive sheet from shifting during movement and affecting the cutting quality.

[0015] 3. By activating the cylinder, the piston rod pushes the pressure plate downward, causing the bottom of the pressure plate to make close contact with the upper surface of the automotive sheet. This ensures that the pressure plate can firmly press and fix the automotive sheet during the cutting process, effectively preventing the sheet from moving and further guaranteeing the cutting quality.

[0027] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an automotive sheet metal shearing device.

[0028] like Figure 1-4As shown, this utility model discloses an automotive sheet metal shearing device, comprising a U-shaped platform 1 and a belt conveyor 2 located below the outlet end of the U-shaped platform 1. Multiple equally spaced conveyor rollers 3 are rotatably connected to the U-shaped platform 1 along its length via bearings. The multiple conveyor rollers 3 are connected by a chain and sprocket assembly. Adjustable-spaced limiting plates 4 are provided on both sides of the inlet end of the U-shaped platform 1. Bidirectional lead screws 11 are rotatably connected to the upper sides of the U-shaped platform 1 via bearing seats. First sliding rods 12 are provided on both sides of the bidirectional lead screws 11, parallel to them. Both ends of the first sliding rods 12 are fixedly connected to the upper surface of the U-shaped platform 1 via fixed seats. A first threaded block 13, threadedly connected to the bidirectional lead screws 11, is provided in the middle of the upper surface of the limiting plate 4. Both sides of the upper surface of the limiting plate 4 are provided with sliders 14 that are slidably connected to the first slide rod 12. One end of the bidirectional lead screw 11 extends to the outside of the bearing seat and is provided with a crank handle. There is a gap between the bottom of the limiting plate 4 and the upper surface of the conveying roller 3. By turning the crank handle, the bidirectional lead screw 11 can be rotated. Under the action of the first threaded block 13, the first slide rod 12 and the sliders 14, the two limiting plates 4 can move away from each other or move closer to each other, thereby adjusting the distance between the two limiting plates 4. This ensures that the car sheet moving on the conveying roller 3 is between the two limiting plates 4, which has a good limiting effect on the car sheet and can effectively prevent the car sheet from shifting during the movement and affecting the cutting quality.

[0029] A U-shaped frame 5 is provided on the upper surface of the outlet end of the U-shaped table 1. A pressure plate 7 that can move up and down is provided inside the U-shaped frame 5. A cylinder 6 is installed in the middle part of the upper surface of the U-shaped frame 5 through a fixed frame. The piston rod of the cylinder 6 passes through the U-shaped frame 5 and is fixedly connected to the middle part of the upper surface of the pressure plate 7. Limit rods 8 are provided at the four corners of the upper surface of the pressure plate 7. Four through holes are provided on the upper surface of the U-shaped frame 5, which correspond one-to-one with the limit rods 8. The through holes are slidably connected to the limit rods 8. By activating the cylinder 6, the piston rod pushes the pressure plate 7 downward, so that the bottom of the pressure plate 7 is in close contact with the upper surface of the automotive sheet. During the cutting process, the pressure plate 7 can firmly press and fix the automotive sheet, which can effectively prevent the automotive sheet from moving during the cutting process, further ensuring the cutting quality. Moreover, the cooperation between the through holes and the limit rods 8 plays a limiting role in the pressure plate 7.

[0030] Both sides of the U-shaped frame 5 are provided with L-shaped plates 9. A one-way lead screw 16 is rotatably connected between the two L-shaped plates 9 via bearings. A motor 15 is mounted on one of the L-shaped plates 9. The shaft of the motor 15 is connected to the one-way lead screw 16. A second threaded block 18 is threaded onto the one-way lead screw 16. An L-shaped seat 17 is provided at the bottom of the second threaded block 18. A cutting motor is mounted on the L-shaped seat 17. A cutting blade 10 is connected to the shaft of the cutting motor. The shaft of the cutting motor passes through the vertical section of the L-shaped seat 17 and is rotatably connected to it via bearings. A second sliding rod 19 is provided between the two L-shaped plates 9, below the one-way lead screw 16, and a sliding hole is provided on the horizontal section of the L-shaped seat 17 to slide with the second sliding rod 19. The second sliding rod 19 and the sliding hole on the L-shaped seat 17 provide a good limiting effect for the second threaded block 18, making the movement of the cutting motor and cutting blade 10 along the width direction of the automotive sheet more stable and reliable when the L-shaped seat 17 drives the cutting seat 17. The length direction of the U-shaped platform 1 is perpendicular to the length direction of the belt conveyor 2, the length direction of the limiting plate 4 is perpendicular to the length direction of the conveyor roller 3, and the length direction of the unidirectional lead screw 16 is parallel to the length direction of the conveyor roller 3. The cut car body panels will fall directly onto the belt conveyor 2 and be conveyed down by the belt conveyor 2, avoiding the phenomenon that the cut car body panels fall directly down and accumulate together, causing damage.

[0031] The working principle of this automotive sheet metal cutting device is as follows: During use, the automotive sheet metal is placed on the conveyor rollers 3 of the U-shaped table 1. By turning the crank handle, the two limiting plates 4 move closer together and contact the side walls of the automotive sheet metal, thus limiting its movement. When the end of the automotive sheet metal moves out of the exit end of the U-shaped table 1, the conveyor rollers 3 are stopped, the cylinder 6 is activated, causing the pressure plate 7 to press against the upper surface of the automotive sheet metal. Then, the motor 15 and the cutting motor are activated, causing the cutting blade 10 to move along the width direction of the automotive sheet metal, thereby cutting it off. The cut automotive sheet metal falls directly onto the belt conveyor 2 and moves along it. Simultaneously, the conveyor rollers 3 continue to transport the automotive sheet metal to the cutting blade 10 for cutting. This process is repeated continuously, allowing for continuous cutting of automotive sheet metal, greatly improving work efficiency and achieving a high degree of automation, significantly saving manpower.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
