Description

Technical Field

[0001] This utility model relates to the field of sheet metal cutting technology, specifically a cutting device with a straightening structure. Background Technology

[0002] Millimeter-wave radars are typically installed at the front, rear, and four corners of a vehicle. They can detect the distance and speed between two vehicles, the distance to obstacles, and blind spots. The principle of millimeter-wave radar is to emit radar waves forward. When the radar waves come into contact with an object, they are reflected back to the millimeter-wave radar. By comparing the emission time and return time of the radar waves, the speed and distance of the object can be detected. In manufacturing, millimeter-wave radar needs to be covered with a shell to protect it. The shell needs to be cut to a specified size during production, and then shaped by cutting, drilling, tapping, and bending. The shaped shell is then assembled with the millimeter-wave radar using fasteners or bolts.

[0003] Existing millimeter-wave radar housing cutting devices require cutting sheet metal into specified sizes. After processing at the factory, the sheet metal is usually rolled into rolls for easy transportation and storage. After being rolled, the surface of the sheet metal is bent. If it is directly fed into the cutting equipment, it may affect the cutting accuracy, resulting in more waste from the scraps generated in subsequent processing. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a cutting device with a straightening structure to solve the technical problem that the curvature of the rolled-up surface of the sheet metal affects the cutting accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting device with a straightening structure, comprising a device body, a straightening component on the device body, and the straightening component including a first hydraulic cylinder and a second hydraulic cylinder, the output end of the second hydraulic cylinder being connected to a pressure block via a piston rod, and the output end of the first hydraulic cylinder being connected to a frame via a piston rod, a pressure plate being connected to the frame via a second spring, and a pressure frame being connected to the frame, a pressure roller and a tension spring being connected to the sides of the pressure frame, a first spring being connected inside the device body, and a bracket being connected to the first spring.

[0006] By adopting the above technical solution, after the first and second hydraulic cylinders are started, the output ends drive the frame and the pressure block to move downward. After the frame moves downward, the pressure roller contacts the plate. As the frame continues to move downward, the two pressure frames rotate and open, thereby pressing the arc at the top of the plate downward. After the pressure frame rotates ninety degrees, it abuts against the pressure plate. At this time, the second spring cooperates with the pressure plate to apply force to the pressure frame, thereby pressing the plate. At the same time, the piston rod on the output end of the second hydraulic cylinder continues to extend, causing the pressure block to apply pressure to the plate. The pressure is applied to the plate by hydraulic pressure, thereby flattening and straightening the plate. At the same time, the bracket is forced to move downward and compress the first spring to prevent the second conveying roller from being crushed.

[0007] Furthermore, a cutting machine is installed under the main body of the device, and a first conveying roller is installed on the main body of the device, while a second conveying roller is installed on the support.

[0008] By adopting the above technical solution, the board is sent out by the second conveyor roller, and then the worker turns on the cutting machine and pushes the board to cut it. After the board is cut, it is sent out by the first conveyor roller.

[0009] Furthermore, the pressure frame is movably connected to the frame, and the pressure block is movably connected to the frame.

[0010] By adopting the above technical solution, after the first and second hydraulic cylinders are started, the output ends drive the frame and the pressure block to move down. After the frame moves down, the pressure roller contacts the plate. As the frame continues to move down, the two pressure frames rotate and open, thereby pressing the arc at the top of the plate downward. Pressure is applied to the plate by hydraulic pressure, thereby flattening and straightening the plate.

[0011] Furthermore, the pressure frame is shaped like a "7", and the bottom of the pressure frame is tilted to one side.

[0012] By adopting the above technical solution, the frame moves down and the pressure roller comes into contact with the board. As the frame continues to move down, the two pressure frames rotate and open, and the pressure roller rotates. At the same time, the tension spring is stretched, which in turn presses the arc at the top of the board downward.

[0013] Furthermore, the cross-section of the pressure block is T-shaped, and the pressure block abuts against the pressure frame.

[0014] By adopting the above technical solution, after the first and second hydraulic cylinders are started, the output ends drive the frame and the pressure block to move downward. After the frame moves downward, the pressure roller contacts the plate. As the frame continues to move downward, the two pressure frames rotate and open. The piston rod on the output end of the second hydraulic cylinder continues to extend, causing the pressure block to apply pressure to the plate.

[0015] Furthermore, the pressure plate abuts against the pressure frame, and there are two pressure plates.

[0016] By adopting the above technical solution, as the frame continues to move downward, the two pressure frames rotate and open, thereby pressing the arc at the top of the plate downward. After the pressure frame rotates ninety degrees, it comes into contact with the pressure plate. At this time, the second spring cooperates with the pressure plate to apply force to the pressure frame, thereby pressing the plate down.

[0017] Furthermore, there are two pressure frames, and the two pressure frames are arranged in a mirror image.

[0018] By adopting the above technical solution, after the frame moves down, the pressure roller comes into contact with the board. As the frame continues to move down, the two pressure frames rotate and open, thereby pressing the arc at the top of the board downward. Pressure is applied to the board through hydraulic pressure, thereby flattening and straightening the board.

[0019] In summary, the present invention has the following main advantages:

[0020] This invention, through the setting of a straightening component, allows the output ends of the first and second hydraulic cylinders to drive the frame and pressure block downwards after activation. The downward movement of the frame brings the pressure roller into contact with the plate. As the frame continues to move downwards, the two pressure frames rotate and open, pressing the arc at the top of the plate downwards. After rotating ninety degrees, the pressure frame abuts against the pressure plate. At this point, the second spring, in cooperation with the pressure plate, applies force to the pressure frame, thus pressing the plate down. Simultaneously, the piston rod on the output end of the second hydraulic cylinder extends continuously, causing the pressure block to apply pressure to the plate. The hydraulic pressure flattens and straightens the plate. At the same time, the support is forced downwards, compressing the first spring to prevent damage to the second conveying roller. The hydraulic structure applies pressure to the plate, flattening it to prevent bending and also preventing damage to the conveying structure, thus ensuring its usability.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] A cutting device with a straightening structure, such as Figures 1-4 As shown, it includes a device body 1, on which a straightening component 4 is provided.

[0029] Specifically, the straightening assembly 4 includes two first hydraulic cylinders 401 and one second hydraulic cylinder 402 installed on one side of the top of the main body 1. The output end of the second hydraulic cylinder 402 is connected to a pressure block 404 via a piston rod. The output ends of the two first hydraulic cylinders 401 are connected to a frame 403 via piston rods. Two pressure plates 409 are respectively connected to the bottom sides of the frame 403 via eight second springs 410. Two pressure frames 405 are respectively connected to the lower part of the inside of the frame 403. The two pressure frames 405 are mirror images arranged along the longitudinal axis centerline of the frame 403. A pressure roller 406 is connected to one side of each of the two pressure frames 405. Two tension springs 411 are connected between the two pressure frames 405. A first spring 408 is connected to the lower part of the inside of the main body 1. A bracket 407 is connected to the top of the first spring 408. Pressure is applied to the plate through the hydraulic structure to flatten the plate to avoid bending, and at the same time to prevent the conveying structure from being damaged and affecting its use.

[0030] See Figure 1 and Figure 4 In the above embodiment, a cutting machine 3 is installed at the bottom of the device body 1, and multiple first conveying rollers 2 are installed at equal intervals at the top of the device body 1. Multiple brackets 407 and first springs 408 are provided, and the multiple brackets 407 and first springs 408 are distributed at equal intervals. Second conveying rollers 5 are installed on the top of the multiple brackets 407. The multiple first conveying rollers 2 and second conveying rollers 5 are mirror images of each other, which facilitates cutting the plate into a specified length and width to facilitate the processing of the millimeter-wave radar shell.

[0031] See Figures 1-3 In the above embodiment, the pressure frame 405 is rotatably connected to the frame 403. The pressure frame 405 is in the shape of a "7". The bottom of the pressure frame 405 is tilted to one side. The pressure block 404 is slidably connected to the frame 403. The cross section of the pressure block 404 is in the shape of a "T". The pressure block 404 and the pressure plate 409 both abut against the pressure frame 405. Pressure is applied to the plate by hydraulic pressure to flatten and straighten the plate.

[0032] The implementation principle of this embodiment is as follows: First, the operator places the plate material for processing the millimeter-wave radar housing on the main body 1 of the device. Then, the plate material is transported to the bottom of the pressure frame 405 by the second conveying roller 5. After the first hydraulic cylinder 401 and the second hydraulic cylinder 402 are started, the output end drives the frame 403 and the pressure block 404 to move down. After the frame 403 moves down, the pressure roller 406 contacts the plate material. As the frame 403 continues to move down, the two pressure frames 405 rotate and open, and the pressure roller 406 rotates. At the same time, the tension spring 411 is stretched, thereby pressing the arc at the top of the plate material downward. After the pressure frame 405 rotates ninety degrees, it abuts against the pressure plate 409. At this time, the second spring 410 cooperates with the pressure plate 409 to apply force to the pressure frame 405 to press the plate material. At the same time, the piston rod on the output end of the second hydraulic cylinder 402 continues to extend, causing the pressure block 404 to apply pressure to the plate material, thereby flattening and straightening the plate material. At the same time, the bracket 407 is forced to move down and compress the first spring 408 to prevent the second conveying roller 5 from being crushed.

[0033] After cutting and straightening are completed, the operator closes the first hydraulic cylinder 401 and the second hydraulic cylinder 402 to reset the straightening component 4. At the same time, the tension spring 411 pulls the two pressure frames 405 to close them. Simultaneously, the first spring 408 loses pressure and drives the support 407 to move upward. Then, the board is sent out through the second conveyor roller 5. After that, the operator turns on the cutting machine 3 and pushes the board to cut it. After the board is cut, it is sent out through the first conveyor roller 2.
