Description

Technical Field

[0001] The invention relates to the technical field of electric box processing, in particular to a laser cutting device for electric box processing. Background Art

[0002] The electrical box, also known as the distribution box, is mainly used to reasonably distribute electrical energy, facilitate the opening and closing of the circuit, and has a high level of safety protection. During the processing and manufacturing of the electrical box, it is necessary to cut the metal plates, and then perform welding and other processing according to the manufacturing requirements.

[0003] The existing patent authorization number is: CN217800478U, which discloses a cutting device for processing electric boxes, including: a cutting table, support frames are fixedly installed on both sides of the surface of the cutting table, and a driving box is fixedly installed on the top of the two support frames. The internal rotation of the driving box is connected to a reciprocating screw, and the surface of the reciprocating screw is threadedly connected to a moving block. The device clamps the two sides of the metal sheet through a concave plate. After the cutting machine completes cutting the metal sheet, the hydraulic telescopic rod is telescopically adjusted to adjust the position of the concave plate, and the concave plate transports the metal sheet to the inside of the carrier plate, and then the threaded rod rotates to drive the two positioning plates to move outward on both sides at the same time, and under the restriction of the limit rod, the concave plate is separated from the metal sheet, which is convenient for the concave plate to carry the next metal sheet, so as to avoid manual removal of the metal sheet and cause hand injuries to the staff. After analyzing the device, it can be found that its main function is to automatically transport metal sheets to increase safety; however, in the actual processing process, the metal sheets processed by the electrical box are mostly collected in a coiling manner. When processing them, the metal sheets need to be automatically stretched and fed. In order to improve the cutting accuracy and speed, laser cutting is now mostly used. However, the existing laser cutting equipment has poor adjustability, which is inconvenient to fully cut metal sheets of different thicknesses. Moreover, for the metal sheet blocks after cutting, there is a lack of the function of grinding them immediately at the cutting point, resulting in the need to add subsequent steps for precise processing of the metal sheets, thereby increasing the processing cost. Moreover, independent power systems are mostly used for the input, cutting, grinding, and output of metal sheets. There is a lack of effective kinetic energy transfer and conversion between the processing steps, resulting in insufficient energy utilization and affecting the operating efficiency of the entire cutting.

[0004] Therefore, in view of the above-mentioned problems, the present technical solution proposes a laser cutting device for electrical box processing. Summary of the invention

[0005] The object of the present invention is to provide a laser cutting device for processing an electrical box to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a laser cutting device for processing an electric box, comprising a laser cutting mechanism, the laser cutting mechanism is used to automatically cut the metal sheet of the electric box, a feeding mechanism is provided at the input end of the laser cutting mechanism, the feeding mechanism is used to automatically control the metal sheet of the electric box to feed toward the laser cutting mechanism, a grinding mechanism that moves reciprocatingly is provided on the upper side of the output end of the laser cutting mechanism, the grinding mechanism is used to automatically grind the cut part of the metal sheet of the electric box after cutting, a discharging mechanism is provided at the bottom of the output end of the laser cutting mechanism, and the metal sheet of the electric box processed by the grinding mechanism is automatically transferred and output under the drive of the discharging mechanism;

[0007] The transmission assembly is arranged on the same side of the feeding mechanism, laser cutting mechanism, discharging mechanism and grinding mechanism. The transmission assembly is used to rotatably connect the driving ends of the feeding mechanism, laser cutting mechanism, discharging mechanism and grinding mechanism into one. A servo motor is connected to one side of the transmission assembly, that is, the transmission assembly is driven by the servo motor to drive the feeding mechanism, laser cutting mechanism, discharging mechanism and grinding mechanism to rotate synchronously, so as to realize an integrated energy-saving operation mode in which a single set of motors simultaneously controls the feeding of metal plates of the electric box, the up and down movement of the laser cutting mechanism for cutting, the grinding mechanism for grinding and the automatic discharging of metal plates, thereby fully reducing the operating cost of the device.

[0008] In an embodiment of the present invention, the bottoms of the feeding mechanism, grinding mechanism, transmission assembly, servo motor, discharging mechanism and laser cutting mechanism are all installed on the base, and a group of control boxes are installed on one side of the top of the base. The control box is electrically connected to the feeding mechanism, grinding mechanism, transmission assembly, servo motor, discharging mechanism, laser cutting mechanism, etc., that is, during processing, the operation of the above-mentioned mechanisms and components can be directly controlled by operating the control box.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting a feeding mechanism to control the automatic feeding of the metal sheet of the electric box, and then transferring it to the cutting table, controlling the automatic lifting of the laser cutting knife to accurately cut it, and then transferring the cut sheet to the end of the cutting table to be finely ground by the grinding roller, and then automatically pushed out again by the push plate, the whole process is automated without manual participation, and a large number of metal sheets of the electric box can be cut with high precision to a certain extent;

[0010] By setting up a transmission component, the kinetic energy of the servo motor is transmitted and converted to control the plate feeding, automatic lifting of the laser cutting knife, circular movement of the grinding roller, and movement of the push plate to discharge the material. The kinetic energy of the servo motor is fully utilized, greatly improving the operating efficiency while reducing the operating cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In the embodiment of the present invention, the bottoms of the feeding mechanism 12, the grinding mechanism 14, the transmission assembly 15, the servo motor 17, the discharging mechanism 19, and the laser cutting mechanism 20 are all installed on the base 10, and a control box 11 is installed on one side of the top of the base 10. The control box 11 is electrically connected to the feeding mechanism 12, the grinding mechanism 14, the transmission assembly 15, the servo motor 17, the discharging mechanism 19, the laser cutting mechanism 20, etc., that is, during processing, the operation of the above-mentioned mechanisms and components can be directly controlled by operating the control box 11.

[0034] In one embodiment of the present invention, see Figure 1-Figure 5 , Figure 8The laser cutting mechanism 20 includes a cutting table 201 arranged parallel to and just above the base 10. The metal sheet of the electric box to be cut moves along the cutting table 201. A group of laser cutting equipment bases 202 are arranged in a lifting manner just above the middle of the cutting table 201. A laser cutting knife 203 is arranged on the lower side of the laser cutting equipment base 202. The laser cutting knife 203 is electrically connected to the control box 11. When the metal sheet of the electric box moving along the cutting table 201 passes under the laser cutting knife 203, the laser cutting knife 203 automatically falls to cut the metal sheet of the electric box. Two groups of lifting rods 204 are symmetrically installed on both sides of the bottom of the cutting table 201. The lifting rods 204 move through the cutting table 2 01 are connected downwardly with a group of connecting plates 206, a swing connecting block 207Ⅰ is fixedly installed in the middle of the bottom of the connecting plate 206, one side of the swing connecting block 207Ⅰ is rotatably connected to a swing connecting block Ⅱ208 through a rotating shaft, and the bottom of the swing connecting block Ⅱ208 is connected to a connecting column 209, the bottom end of the connecting column 209 is connected to a screw rod 210, the bottom end of the screw rod 210 is threadedly connected to a screw barrel 211, and the bottom end of the screw barrel 211 is rotatably connected to a connecting base, and the depth of the screw rod 210 placed inside the screw barrel 211 can be adjusted by rotating the screw barrel 211, so as to adjust the initial height of the connecting column 209, so that the lifting stroke of the laser cutting knife 203 can be adjusted to a certain extent;

[0035] A swing rod 212 is rotatably connected to one side of the connecting base, a group of rotating cylinders 213 are arranged in the middle of the swing rod 212, and a sliding rod 216 is installed at the end of the swing rod 212 away from the connecting base, wherein a rod shaft 214 is movably passed through the middle of the rotating cylinder 213, and both ends of the rod shaft 214 are rotatably supported by a U-shaped support frame 215, and the bottom of the U-shaped support frame 215 is fixed on the base 10, and a group of rotating disks 217 are arranged at the end of the sliding rod 216, and the center of the rotating disk 217 on one side away from the swing rod 212 is connected to the transmission component 15, and a driving slide rail 218 is opened on the side of the rotating disk 217 facing the sliding rod 216, and the driving slide rail 218 is set to a quasi-circular structure, and a An arc-shaped structure is recessed toward the center of the rotating disk 217. When the transmission assembly 15 drives the rotating disk 217 to rotate, the sliding rod 216 rotates inside the driving slide rail 218 to drive the swing rod 212 to swing around the rotating cylinder 213, thereby driving the connecting plate 206 on the top of the screw cylinder 211 and the screw rod 210 to move up and down, and then, under the connection of the lifting rod 204, the laser cutting knife 203 is driven to rise and fall cyclically, so as to approach and cut the passing electric box metal sheet, thereby realizing the operation mode of using the servo motor 17 to drive the transmission assembly 15 to rotate, and then driving the laser cutting knife 203 to rise and fall cyclically to approach the electric box metal sheet for cutting;

[0036] Specifically, in order to keep the lifting rod 204 stable during lifting, a positioning block 205 is mounted on the lifting rod 204 below the cutting table 201, and one side of the positioning block 205 is mounted on the feeding mechanism 12 through a fixing rod;

[0037] It should be noted that, since the laser cutting knife 203 has a certain cutting distance when it is running, and when facing the electrical box metal plates of different thicknesses, in order to maintain the accuracy and adequacy of the cutting, the laser cutting knife 203 is controlled to move up and down, and cut close to the electrical box metal plate, which can greatly improve the cutting efficiency;

[0038] Among them, the laser cutting equipment base 202 and the laser cutting blade 203 constitute a simple laser cutting machine, and its operating principle is a device that uses a high-power laser beam to cut materials. It focuses the laser beam to a very small point to generate a very high energy density, so that the material quickly melts, vaporizes or reaches the combustion point to achieve a cutting effect. The specific operation method when used in this device will not be repeated here, but it does not affect the integrity of this technical solution.

Then, the elastic winding plate 129 is elastically connected to the swing shaft in cooperation with the spring 130, thereby driving the swing shaft to swing. Then, under the connection of the connecting rod 125, the positioning slide bar is driven to move back and forth inside the positioning slide groove 124, thereby controlling the metal sheet of the electric box placed in the steering limit channel to vibrate forward, and cooperate with the release driving force of the metal sheet winding roller 121 to stably transfer and transport it toward the cutting table 201.
