Description

Technical Field

[0001] The invention belongs to the technical field of cutting devices, and in particular relates to a machine tool cutting device. Background Art

[0002] Metal sheets are basic raw materials in the manufacturing of many industrial products. Different products have strict requirements on the size specifications of metal sheets. Shearing machines can accurately cut large-format metal sheets according to preset sizes to ensure that the size deviation of the cutting material is extremely small and meet the requirements of subsequent processing for the size accuracy of the plate. For example, a cutting device for machine tool processing is proposed in patent announcement number CN118699454A.

[0003] After long-term use, the internal cutting blades of existing machine tool cutting devices are worn due to continuous high-intensity work. When the worn cutting blades are used to shear metal sheets, the contact between the cutting edge and the sheet is uneven, resulting in the material in some areas being unable to be cut cleanly, being squeezed and deformed to form burrs. Severe burrs not only damage the appearance of the sheet, but also cause safety hazards in subsequent processing or use, such as scratching operators or affecting assembly accuracy. When cutting metal sheets, for safety reasons, operators need to maintain a certain safe distance from the device, which makes it difficult for them to detect the burr problem caused by the wear of the cutting blade in time.

[0021] The upper side wall of the mounting frame 3 is fixedly connected to a plurality of vertical pipes 23, and the upper ends of the plurality of vertical pipes 23 are fixedly connected to the same curved pipe 24, which is an inverted L-shaped structure.

[0023] The side walls of the two support frames 81 close to each other are connected with an extension plate 39. The upper surface of the extension plate 39 and the upper end of the auxiliary roller 13 are in the same straight line, which can further enhance the support strength of the metal sheet cutting location.

[0024] The operating principle of the present invention is now described as follows: the metal sheet to be sheared is placed on the surface of the front support frame 81, and then the metal sheet is moved so that the front end of the metal sheet is located in the clamping frame 9. Then the operator transmits an electrical signal to the PLC controller 2 through the control box 7. After receiving the electrical signal, the PLC controller 2 first controls the clamping electric push rod 10 to work, and the clamping electric push rod 10 clamps and fixes the metal sheet below through the clamping plate 11. Then the PLC controller 2 controls the second electric slide rail 82 to work, and the second electric slide rail 82 will drive the metal sheet to move forward to a set distance through the clamping frame 9, so that the metal sheet is between the electric cutting disc 6 and the auxiliary roller 13. Then the PLC controller 2 controls the vacuum pump 27 to work, and the vacuum pump 27 extracts the gas inside the dust box 26, so that the inside of the dust box 26 is in a negative pressure state, and the external gas will enter the dust box 26 through the dust hood 25, the vertical pipe 23 and the curved pipe 24, so that the metal powder generated during the cutting process of the metal sheet can be adsorbed; Then the PLC controller 2 controls the first electric push rod 5 to work, and the first electric push rod 5 drives the electric cutting disc 6 to move downward to the set position, so that the lower edge of the electric cutting disc 6 is in the cutting groove 14, and then the PLC controller 2 controls the first electric slide rail 4 and the third electric slide rail 121 to move to the left synchronously, and the metal sheet is sheared through the mutual cooperation of the electric cutting disc 6 and the cutting groove 14, and while the first electric slide rail 4 and the third electric slide rail 121 move to the left synchronously, the PLC controller 2 also controls the second electric push rod 152 on the right to work, and the second electric push rod 152 on the right drives the detection cylinder 16 on the right When the electric cutting disc 6 is worn out after long-term use, the cutting edge of the electric cutting disc 6 is unevenly in contact with the sheet, causing the material in some areas to be unable to be cut cleanly, being squeezed and deformed to form burrs. When the right detection rod 22 contacts the burr at the cutting position, the burr will push the rod wall of the right detection rod 22 to the right (the detection rod 22 and the burr are in longitudinal contact, and the pushing force of the burr is sufficient to push the detection rod 22 to rotate), so that the right detection rod 22 drives the vertical rod 22 on the right. The rod 17 rotates, and the vertical rod 17 on the right side drives the two limit plates 18 to rotate. The limit plate 18 on the right side drives the conductive rod 20 on the lower side to rotate, so that the conductive plate contacts the arc-shaped conductive plate 21 below. The conductive rod 20 is electrically connected to the external power supply, and the arc-shaped conductive plate 21 is electrically connected to the PLC controller 2. When the conductive rod 20 contacts the arc-shaped conductive plate 21, an electrical signal is transmitted to the PLC controller 2. After receiving the electrical signal, the PLC controller 2 controls the first control valve 30 to close and the second control valve 31 to open for 0.1 seconds, so that part of the gas extracted by the vacuum pump 27 enters the trigger box 2 through the air inlet pipe 29. 8, so that the air pressure in the space below the piston plate 32 increases, the piston plate 32 will move upward by one-fifth of the distance, and after the first control valve 30 is opened and the second control valve 31 is closed, the gas below the piston plate 32 will be slowly discharged through the microporous plate 33. Within one hour, the gas in the space below the piston plate 32 will be completely discharged. Within one hour, if the detection rod 22 is continuously triggered for more than five times, the piston plate 32 will move upward and squeeze the trigger switch 34. The trigger switch 34 will drive the buzzer inside the control box 7 through the PLC controller 2 to work, reminding the operator that the electric cutting disc 6 is worn and needs to be repaired in time; The operator roughly observes the wear of the electric cutting disk 6 with the naked eye. When it is found that there is a gap on the surface of the electric cutting disk 6, the cutting part of the electric cutting disk 6 needs to be replaced. When it is detected that there is no gap on the surface of the electric cutting disk 6, the operator can transmit an electrical signal to the PLC controller 2 through the control box 7. After receiving the electrical signal, the PLC controller 2 will control the first electric slide rail 4 to drive the electric cutting disk 6 to move right to the initial position, and then the PLC controller 2 controls the horizontal electric push rod 361 to work. The horizontal electric push rod 361 will drive the moving frame 362 to move in the direction close to the electric cutting disk 6, so that the cutting part of the electric cutting disk 6 is in the moving frame 362. Then the PLC controller 2 first controls the electric cutting disk 6 to rotate at a high speed, and controls the front repair electric push rod 37 to drive the front grinding seat 38 to move backward. When the front grinding seat 38 contacts the electric cutting disk 6, it will An interaction force is generated. A pressure sensor is provided between the repair electric push rod 37 and the grinding seat 38. After the pressure sensor on the front side detects that the extrusion force between the front grinding seat 38 and the electric cutting disk 6 reaches the set threshold value (50N), the pressure sensor on the front side will control the front repair electric push rod 37 to stop working through the PLC controller 2, and use the front grinding seat 38 to grind the front side of the electric cutting disk 6 for ten seconds. When the front side of the electric cutting disk 6 is ground and contacted, repeat the above steps and grind the back side of the electric cutting disk 6 for ten seconds to restore the electric cutting disk 6 to a sharp state, avoiding the cutting device from continuing to use the severely worn electric cutting disk 6 to cut the metal sheet, which will reduce the cutting quality of the metal sheet, and the electric cutting disk 6 needs to be replaced with a new cutting part after two grinding operations to avoid excessive grinding and adsorption of the cutting part, which will cause problems with the quality of the cutting part.
