[0002] A cold shear machine is a common metal processing equipment used for shearing metal materials. It consists of a shearing mechanism, a transmission system, and a control system.

[0003] Currently, when using a cold shear machine to cut pipes, it is usually necessary to cut the pipes into materials of the same length. Therefore, the pipes need to be fed to the shearing nozzle, and a certain length of pipe needs to pass through the nozzle before cutting. During this process, it is necessary to control the length of the pipes after passing through the shearing nozzle to ensure that the pipes to be cut reach the appropriate length. Based on this, an auxiliary device for cold shear machines is proposed to solve the above problems. Utility Model Content

The base frame is located on one side of the cold shearing machine as a whole. A fixed frame is installed on the upper end of the base frame. Several placement plates are installed on the upper end of each fixed frame. Each placement plate has a through groove. A rotating shaft is rotatably connected inside the fixed frame below the through groove. A rotating roller is installed on the surface of each rotating shaft.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1 to 4As shown, the auxiliary device for cold shearing in this embodiment includes a base frame 1 and a cold shear machine assembly 2. The base frame 1 is located on one side of the cold shear machine assembly 2. A fixed frame 3 is installed on the upper end of the base frame 1. Several placement plates 4 are installed on the upper end of each fixed frame 3. The placement plates 4 are arc-shaped and used to place the pipe material. Each placement plate 4 has a through groove 5. A rotating shaft 6 is rotatably connected inside the fixed frame 3 below the through groove 5. A rotating roller 7 is installed on the surface of each rotating shaft 6. The rotating roller 7 is located inside the through groove 5. Adjacent rotating shafts 6 are connected by a linkage mechanism. The linkage mechanism drives multiple rotating shafts 6 to rotate. The rotating roller 7 on the surface of the rotating shaft 6 contacts the pipe material to realize the conveying of the pipe material. A detection disc 9 is installed on the surface of one rotating shaft 6. A sensor assembly 10 is installed on the fixed frame 3 on one side of the detection disc 9. The sensor assembly 10 is for angle rotation. The sensor, specifically the angle rotation sensor, can detect the number of rotations of the magnet 11. An angle rotation sensor is a relatively mature technology in the sensor field, so it will not be described in detail. The magnet 11 is mounted on the surface of the detection disk 9 on one side of the sensor assembly 10. When the rotating shaft 6 rotates, it drives the detection disk 9 to rotate. The sensor assembly 10 detects the number of rotations of the magnet 11 on the detection disk 9 and calculates the length of the conveyed pipe material based on the diameter of the rotating roller 7, facilitating the processing of pipe materials of the same length. An auxiliary pressing mechanism is installed on the upper end of the fixed frame 3 near the cold shear machine assembly 2. This mechanism is used to press the upper end of the pipe material to prevent it from shaking up and down during cold shearing. A controller, a PLC control module, is installed on the fixed frame 3. The controller controls the cold shear machine to perform the shearing operation based on the length of the pipe material's movement.

[0023] Specifically, the linkage mechanism includes pulleys 801, belts 802, and a motor 803. Both ends of the outermost rotating shaft 6 extend to the outside of the fixed frame 3. The motor 803 is mounted on the surface of the fixed frame 3 on one side of the outermost rotating shaft 6. The output end of the motor 803 is connected to the outermost rotating shaft 6. One end of each rotating shaft 6 extends to the outside of the fixed frame 3, and each rotating shaft 6 is mounted with a pulley 801. Adjacent pulleys 801 are connected by belts 802. When the motor 803 drives the rotating shaft 6 to rotate, the rotating shaft 6 drives the other rotating shafts 6 to rotate through the pulleys 801 and belts 802, so that multiple rotating shafts 6 rotate in the same direction.

[0024] Furthermore, the auxiliary pressing mechanism includes a mounting frame 1201, an adjusting screw 1202, a movable frame 1203, a knob 1204, and a pressure roller 1205. The mounting frame 1201 is installed on the upper end of the fixed frame 3 near the cold shear machine assembly 2. The adjusting screw 1202 is installed on the mounting frame 1201 through a screw hole. The movable frame 1203 is installed at the lower end of the adjusting screw 1202 inside the mounting frame 1201. The pressure roller 1205 is rotatably connected to the movable frame 1203. The knob 1204 is installed on the upper end of the adjusting screw 1202. By adjusting the knob 1204, the adjusting screw 1202 is driven to rotate. The adjusting screw 1202 drives the pressure roller 1205 on the movable frame 1203 to contact the pipe material, thereby achieving auxiliary pressing of the pipe material and preventing the pipe material from shaking up and down during the cold shear machine cutting, which would affect the cutting effect.

[0025] Furthermore, an anti-slip layer 13 is installed on the surface of the rotating roller 7. The surface of the anti-slip layer 13 has a certain friction to prevent the rotating roller 7 from being unable to drive the pipe material for conveying when it rotates.

[0026] Furthermore, four electric push rods 14 are installed in a rectangular shape at the lower end of the base frame 1. Support blocks 15 are installed at the lower end of the electric push rods 14. By controlling the extension and retraction of the electric push rods 14, the height of the base frame 1 can be adjusted, so that the placement plate 4 and the cold shear machine as a whole 2 can be kept at the same height. It has strong applicability and is suitable for cold shear machines of various heights. The support blocks 15 are used to provide cable passage for the electric push rods 14.

[0027] Furthermore, each support block 15 is equipped with a rotating wheel 16 at its lower end. The rotating wheel 16 facilitates the movement of the entire device and improves the ease of movement.

[0028] The usage method of this embodiment is as follows: First, position the base frame 1 on one side of the cold shear machine assembly 2, and place the pipe material to be conveyed on the placement plate 4. Then, rotate the knob 1204 to drive the adjusting screw 1202 to rotate. The adjusting screw 1202 drives the pressure roller 1205 on the moving frame 1203 to contact the pipe material, thus assisting in pressing the pipe material and preventing it from shaking up and down during cold shearing, which would affect the shearing effect. Then, control the extension and retraction of the electric push rod 14 to adjust the height of the pipe material on the placement plate 4, ensuring that the lower end of the pipe material is level with the lower cutting edge of the cold shear machine assembly 2. Then, align one end of the pipe material with the cutting edge of the cold shear machine assembly 2 vertically, while ensuring the sensor assembly 10 and the magnet block 11 are in corresponding positions. Finally, control the linkage mechanism. When the motor 803 in the structure rotates, the rotating shaft 6 rotates. The rotating shaft 6 drives the other rotating shafts 6 to rotate through the pulley 801 and belt 802, so that multiple rotating shafts 6 rotate in the same direction. At the same time, the rotating roller 7 on the surface of the rotating shaft 6 contacts the tube material. The rotating roller 7 drives the tube material to be conveyed. At the same time, when the rotating shaft 6 rotates, it drives the detection disk 9 to rotate. The sensor assembly 10 detects the number of rotations of the magnet block 11 on the detection disk 9 and calculates the length of the conveyed tube material according to the diameter of the rotating roller 7. After the tube material reaches the appropriate length, the cold shear machine 2 cuts the tube material. Then the sensor assembly 10 recalculates the number of rotations to achieve continuous processing, which is convenient for processing tube materials of the same length.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
