Description

Technical Field

[0001] This invention belongs to the field of laser cutting technology, specifically relating to a laser cutting device for cable tray production. Background Technology

[0002] Laser cutting equipment for cable tray production uses a high-power fiber laser as its core and is compatible with commonly used cable tray profiles such as channel steel, angle steel, and galvanized sheet. The CNC system provides precise positioning, resulting in smooth, burr-free cuts with a small heat-affected zone, and can efficiently cut various holes and irregular shapes.

[0003] Patent publication number CN118513666B relates to a positioning laser cutting device and method for cable tray production. The issue is that when cable trays are placed on a serrated cutting bed, high-temperature molten slag easily comes into contact with the surface after being blown out, forming a slag layer of a certain thickness after prolonged use. This results in an uneven machine bed surface, affecting processing and cutting accuracy. The proposed solution includes a machine body with a slag cleaning module inside, and a processing bed frame with multiple toothed plates on its inner wall. This patented positioning laser cutting device and method for cable tray production ensures cutting accuracy. During use, the device can clean the slag from the toothed plate surface, preventing the slag layer from accumulating and affecting the flatness of the machine bed surface, thus ensuring cutting accuracy and improving the device's performance.

[0004] In the aforementioned patent, the accumulation of slag layer to avoid affecting the flatness of the machine tool bed is avoided, thereby ensuring the cutting accuracy of the device during cutting and improving the device's performance. However, during the plate cutting process, if the plate is not centered or tilted, it will increase the positioning work of the cutting equipment, resulting in a reduction in cutting efficiency. Therefore, a laser cutting device for cable rack production with positioning effect is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a laser cutting device for cable tray production, so as to solve the problem that the position of the plate is not centered or tilted, which increases the positioning work of the cutting device and leads to a decrease in cutting efficiency.

[0006] To achieve the above objectives, the present invention provides a laser cutting equipment for cable rack production, including an equipment table and a pusher plate positioning device. The equipment platform is equipped with a lifting frame above it, and the output end of the lifting frame is equipped with a lifting rod. The push plate positioning device includes a lifting plate that slides through the surface of the equipment platform. A connecting block is fixedly connected to the lower part of the lifting plate. A connecting rod is rotatably installed inside the connecting block. A fixed rod is rotatably connected to the end of the connecting rod away from the connecting block. A movable plate is fixedly connected to the surface of the fixed rod. A sliding groove is formed on the surface of the movable plate. An L-shaped rod is slidably connected inside the sliding groove. A pressure rod is fixedly connected to the lower part of the lifting rod. A spring is provided between the L-shaped rod and the sliding groove. The movement of the fixed rod causes the movable plate to move closer to the lifting plate, and the movement of the movable plate causes the L-shaped rod to move closer to the lifting plate.

[0007] In one or more embodiments of the present invention, the surface of the lifting rod is provided with a laser cutting mechanism, and the inside of the equipment platform is provided with a toothed plate. The laser cutting mechanism is moved to a suitable position by the lifting frame and the lifting rod, and then the lifting frame is activated to drive the lifting rod and the laser cutting mechanism to move downward.

[0008] In one or more embodiments of the present invention, the push plate positioning device is provided in two sets and symmetrically distributed around the equipment table. A second spring is provided between the lifting plate and the equipment table. The two sets of push plate positioning devices allow the L-shaped rods in the two sets to approach each other and push the raw material plate to move in the center of the equipment table, avoiding the position of the raw material plate being tilted or off-center, which would increase the positioning process of the equipment cutting.

[0009] In one or more embodiments of the present invention, the equipment platform has an internal clearance groove 1, and the lifting plate has an external clearance groove 2.

[0010] In one or more embodiments of the present invention, the surface of the pressure rod is provided with a flattening device for preventing the sheet material from warping. The flattening device includes a horizontal plate, which is fixedly connected to the surface of the pressure rod. The surface of the horizontal plate slides and a flattening frame passes through it. A No. 3 spring is provided between the flattening frame and the lifting rod. When the flattening frame continues to move downward, it will move upward relative to the horizontal plate at the left and right lower sides of the raw material sheet and squeeze the No. 3 spring. During this process, the flattening frame will flatten the warped raw material sheet, avoiding the impact of local warping of the raw material sheet on processing accuracy during processing.

[0011] In one or more embodiments of the present invention, the flattening device further includes a fixing frame, which is fixedly connected to the lower part of the flattening frame. The fixing frame is provided with ball bearings inside. The ball bearings move downward to contact the raw material plate and can roll along the path of the laser cutting mechanism while flattening the plate, so as to avoid displacement of the raw material plate due to changes in the cutting path during the flattening process, thereby further improving the processing accuracy.

[0012] In one or more embodiments of the present invention, the surface of the movable plate is provided with a matching device for assisting the push plate. The matching device includes a vertical plate. A limiting groove is opened on the surface of the movable plate. The vertical plate is disposed inside the limiting groove. A fixing rod two is fixedly connected to the lower part of the vertical plate. A connecting rod two is rotatably connected to the surface of the fixing rod two. A connecting block two is fixedly connected to the end of the connecting rod two away from the fixing rod two. When the vertical plate continues to move, the tooth block one and the tooth block two will repeatedly contact and match and generate vibration. The vibration process will be transmitted to the surface of the L-shaped rod through the movable plate.

[0013] In one or more embodiments of the present invention, a toothed block 1 is fixedly connected to the side wall of the vertical plate, a toothed block 2 is slidably connected to the surface of the limiting groove, and a No. 4 spring is provided between the toothed block 2 and the limiting groove. When the toothed block 1 moves to contact and squeeze the toothed block 2 to move, the toothed block 2 will squeeze the No. 4 spring to contract.

[0014] In one or more embodiments of the present invention, the sides of the tooth block one and the tooth block two that are close to each other are respectively set as arc surface one and arc surface two, and the tooth block one and the tooth block two mesh.

[0015] In one or more embodiments of the present invention, the upper part of the vertical plate contacts the bottom of the toothed plate, and the second connecting block is fixedly connected to the moving plate. Since the upper part of the vertical plate contacts the bottom of the toothed plate, the vertical plate rubs against the toothed plate during the movement. The vibration generated by the friction can effectively remove the welding slag adhering to the surface of the toothed plate after each welding, reducing the subsequent manual maintenance cost.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) The laser cutting equipment for cable rack production uses a lifting rod, a linkage pressure rod, a lifting plate, and multiple sets of linkage mechanisms to drive two sets of L-shaped rods to approach each other and automatically push the raw material plate to the center of the equipment table, avoiding the problem of plate tilting or offset; eliminating the extra positioning process, shortening the processing preparation time, and significantly improving the cutting efficiency; at the same time, the No. 1 spring equipped with the L-shaped rod can flexibly deform according to different sizes of plates, which not only ensures the clamping stability during positioning, but also adapts to various specifications of raw materials, eliminating the need for frequent adjustment of equipment parameters, enhancing the versatility and ease of operation of the equipment, and reducing the technical requirements for operators.

[0017] (2) In the laser cutting equipment for cable rack production, the pressure rod moves down and drives the flattening frame to operate simultaneously. After the flattening frame contacts the raw material plate, it achieves adaptive adjustment through the elastic deformation of the No. 3 spring. It can flatten the warped plate and eliminate the influence of local protrusions on the processing accuracy. It can also be compatible with raw material plates of different thicknesses. In addition, the fixed frame at the bottom of the flattening frame has built-in ball bearings. While flattening the plate, it can roll along the laser cutting path, effectively limiting the displacement of the plate and further ensuring the stability of the cutting process.

[0018] (3) The laser cutting equipment for cable rack production has a linkage connecting rod, vertical plate and toothed block structure when the moving plate moves. Vibration is generated by the repeated meshing of toothed block one and toothed block two. The vibration is transmitted to the raw material plate through the L-shaped rod, which can reduce the contact area between the bottom of the plate and the toothed plate, avoid the plate from being scratched by direct dragging during the positioning and pushing process, and ensure the surface accuracy of the raw material after forming. At the same time, the friction vibration between the vertical plate and the bottom of the toothed plate can automatically remove the welding slag attached to the surface of the toothed plate without manual cleaning, which reduces the equipment maintenance cost, extends the service life of the toothed plate, ensures the long-term stable operation of the equipment, and reduces the production loss caused by maintenance downtime.

[0021] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] To keep the drawings concise, each drawing only schematically shows the parts relevant to the invention; these do not represent the actual structure of the product.

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figures 1-7 As shown, it illustrates a laser cutting device for cable rack production according to an embodiment of the present invention, including a machine platform 1 and a push plate positioning device. Among them, a lifting frame 2 is installed above the equipment platform 1, and a lifting rod 3 is installed at the output end of the lifting frame 2; The push plate positioning device includes a lifting plate 6, which slides through the surface of the equipment platform 1. A connecting block 7 is fixedly connected to the lower part of the lifting plate 6. A connecting rod 8 is rotatably installed inside the connecting block 7. A fixed rod 9 is rotatably connected to the end of the connecting rod 8 away from the connecting block 7. A movable plate 10 is fixedly connected to the surface of the fixed rod 9. A sliding groove 1001 is opened on the surface of the movable plate 10. An L-shaped rod 11 is slidably connected inside the sliding groove 1001. A pressure rod 12 is fixedly connected to the lower part of the lifting rod 3. A spring 13 is provided between the L-shaped rod 11 and the sliding groove 1001. The movement of the fixed rod 9 drives the movable plate 10 to move closer to the lifting plate 6. The movement of the movable plate 10 drives the L-shaped rod 11 to move closer to the lifting plate 6.

[0028] The surface of the lifting rod 3 is equipped with a laser cutting mechanism 4, and the inside of the equipment platform 1 is equipped with a toothed plate 5. The laser cutting mechanism 4 is moved to a suitable position by the lifting frame 2 and the lifting rod 3, and then the lifting frame 2 is activated to drive the lifting rod 3 and the laser cutting mechanism 4 to move downward.

[0029] Two sets of push plate positioning devices are provided and symmetrically distributed around the equipment platform 1. A second spring 14 is provided between the lifting plate 6 and the equipment platform 1. The two sets of push plate positioning devices make the L-shaped rods 11 in the two sets approach each other and push the raw material plate to move in the center of the equipment platform 1, so as to avoid the position of the raw material plate being tilted or not centered, which would increase the positioning process of the equipment cutting.

[0030] The equipment platform 1 has an internal clearance groove 101, and the lifting plate 6 has an external clearance groove 601 on its surface.

[0031] In this embodiment: the raw material plate is placed above the toothed plate 5. The laser cutting mechanism 4 is moved to a suitable position by the lifting frame 2 and the lifting rod 3. Then, the lifting frame 2 is activated, which drives the lifting rod 3 and the laser cutting mechanism 4 to move downward. The downward movement of the lifting rod 3 drives the pressure rod 12 to move downward. The pressure rod 12 moves downward and contacts and presses the lifting plate 6 to move downward. The downward movement of the lifting plate 6 drives the connecting block 7 to move downward. The downward movement of the connecting block 7 drives one end of the connecting rod 8 to move downward. The downward movement of one end of the connecting rod 8 drives the fixing rod 9 to move closer to the lifting plate 6 through the other end. The movement of the fixing rod 9 drives the moving plate 10 to move closer to the lifting plate 6. The moving plate 10 moves the L-shaped rod 11 towards the side closer to the lifting plate 6. Since there are two sets of push plate positioning devices, the L-shaped rods 11 in the two sets move closer to each other and push the raw material plate to move in the center of the equipment table 1. This avoids the raw material plate being tilted or out of center, which would increase the positioning process of the equipment cutting and improve cutting efficiency. At the same time, when facing raw material plates of different sizes, the L-shaped rod 11 will squeeze the first spring 13 when it contacts the raw material plate, and adapts through the deformation of the first spring 13 in the two sets, improving the adaptability to different raw material plates. In addition, the first spring 13 can effectively maintain the stability during the positioning process and avoid wear caused by rigid push and pull.

[0032] like Figures 1-7 As shown, in another embodiment of the present invention, the surface of the pressure rod 12 is provided with a flattening device for preventing the board from warping. The flattening device includes a horizontal plate 151, which is fixedly connected to the surface of the pressure rod 12. The surface of the horizontal plate 151 slides and passes through a flattening frame 152. A third spring 153 is provided between the flattening frame 152 and the lifting rod 3. As the flattening frame 152 continues to move downward, it will move upward relative to the horizontal plate 151 from the left and right sides of the raw material board and squeeze the third spring 153. During this process, the flattening frame 152 will flatten the warped raw material board, avoiding the local warping of the raw material board during processing, which would affect the processing accuracy.

[0033] The flattening device also includes a fixed frame 154, which is fixedly connected to the bottom of the flattening frame 152. The fixed frame 154 is equipped with a ball bearing 155. The ball bearing 155 moves downward to contact the raw material plate. While flattening, it can roll along the path of the laser cutting mechanism 4 to avoid displacement of the raw material plate due to changes in the cutting path during the flattening process, thereby further improving the processing accuracy.

[0034] In this embodiment: As the pressure rod 12 moves downward, it drives the horizontal plate 151 to move downward. The downward movement of the horizontal plate 151 drives the flattening frame 152 to move downward. The flattening frame 152 will contact and squeeze the raw material plate as it moves downward. As the flattening frame 152 continues to move downward, it will move upward relative to the horizontal plate 151 on the left and right sides of the raw material plate and squeeze the No. 3 spring 153. During this process, the flattening frame 152 will flatten the warped raw material plate, avoiding the local warping of the raw material plate during processing, which will affect the processing accuracy. At the same time, it can flatten raw material plates of different thicknesses, further improving the adaptability of the equipment. As the flattening frame 152 moves downward, it will drive the fixed frame 154 to move downward. The downward movement of the fixed frame 154 will drive the ball bearings 155 inside it to move downward. The ball bearings 155 move downward and contact the raw material plate. While flattening, they can also roll along the path of the laser cutting mechanism 4, avoiding displacement of the raw material plate due to changes in the cutting path during the flattening process, and further improving the processing accuracy.

[0035] like Figures 1-7 As shown, in another embodiment of the present invention, the surface of the movable plate 10 is provided with a matching device for assisting the push plate. The matching device includes a vertical plate 161. A limiting groove 1002 is opened on the surface of the movable plate 10. The vertical plate 161 is disposed inside the limiting groove 1002. A fixing rod 162 is fixedly connected to the lower part of the vertical plate 161. A connecting rod 163 is rotatably connected to the surface of the fixing rod 162. A connecting block 164 is fixedly connected to the end of the connecting rod 163 away from the fixing rod 162. When the vertical plate 161 continues to move, the tooth block 165 and the tooth block 166 will repeatedly contact and match and generate vibration. The vibration process will be transmitted to the surface of the L-shaped rod 11 through the movable plate 10.

[0036] A toothed block 165 is fixedly connected to the side wall of the vertical plate 161, and a toothed block 166 is slidably connected to the surface of the limiting groove 1002. A fourth spring 167 is provided between the toothed block 166 and the limiting groove 1002. When the toothed block 165 moves to contact and squeeze the toothed block 166 to move, the toothed block 166 will squeeze the fourth spring 167 to contract.

[0037] The sides of tooth block 165 and tooth block 2166 that are close to each other are respectively set as arc surface 1 and arc surface 2, and tooth block 165 and tooth block 2166 mesh.

[0038] The upper part 161 of the vertical plate contacts the bottom of the toothed plate 5, and the connecting block 164 is fixedly connected to the moving plate 10. Since the upper part of the vertical plate 161 contacts the bottom of the toothed plate 5, the vertical plate 161 rubs against the toothed plate 5 during the movement. The vibration generated by the friction can effectively remove the welding slag that adheres to the surface of the toothed plate 5 after each welding, reducing the subsequent manual maintenance cost.

[0039] In this embodiment: During the movement of the moving plate 10, the connecting block 2 164 moves. The movement of the connecting block 2 164 causes one end of the connecting rod 2 163 to move. The movement of one end of the connecting rod 2 163 causes the fixing rod 2 162 to move in the direction perpendicular to the moving plate 10 through the other end. The movement of the fixing rod 2 162 causes the vertical plate 161 to move. The movement of the vertical plate 161 causes the toothed blocks 165 on both sides of it to move. The toothed blocks 165 move and contact and squeeze the toothed blocks 2 166 to move. When the toothed blocks 2 166 move, they will squeeze the fourth spring 167 to contract. Then, the vertical plate 161 continues to move, causing the toothed blocks 165 to contact the toothed blocks 2 166. Repeated contact and vibration are generated. The vibration is transmitted to the surface of the L-shaped rod 11 through the moving plate 10. The L-shaped rod 11 plays an auxiliary role in pushing and positioning the raw material plate, reducing the contact between the bottom of the raw material plate and the toothed plate 5, avoiding scratches caused by dragging the raw material plate directly on the surface of the toothed plate 5, and improving the accuracy of the raw material after forming. At the same time, since the top of the vertical plate 161 contacts the bottom of the toothed plate 5, the vertical plate 161 rubs against the toothed plate 5 during the movement. The vibration generated by the friction can effectively remove the welding slag adhering to the surface of the toothed plate 5 after each welding, reducing the subsequent manual maintenance cost.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
