Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and in particular to an automated sheet metal laser cutting device and a processing technology thereof. Background Art

[0002] Laser cutting is the process of focusing the laser emitted from a laser into a high-power density laser beam through an optical path system. The laser beam is irradiated onto the surface of the workpiece, causing the workpiece to reach its melting point or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the beam moves relative to the workpiece, a slit is eventually formed in the material, thereby achieving the purpose of cutting.

[0003] Laser cutting replaces traditional mechanical knives with invisible light beams. It has the characteristics of high precision, fast cutting, no restrictions on cutting patterns, automatic typesetting to save materials, smooth incisions, and low processing costs. Laser cutting under existing technology usually places the plate on the processing table, but when processing some special-shaped sheet metal parts, due to the different shapes of the sheet metal parts, it is inconvenient to position the sheet metal parts each time, which will affect production efficiency. Summary of the invention

[0004] In order to solve the problem that laser cutting in the prior art usually involves placing the plate on a processing table, but when processing some special-shaped sheet metal parts, it is inconvenient to position the sheet metal parts each time due to the different shapes of the sheet metal parts, the present application provides an automated sheet metal laser cutting equipment, and the specific solution is as follows.

[0005] An automated sheet metal laser cutting device comprises a workbench, on which a transport component and a cutting component are arranged, wherein the transport component is used to transport a workpiece toward the workbench, and the cutting component is used to laser cut the workpiece, and the workbench is further provided with a transport component, wherein the transport component is used to drive the transport component and the cutting component to move; A welding seat is provided on the workbench, a mounting seat is provided on the lower side of the welding seat, a lower mold for casting a workpiece is detachably connected to the mounting seat, a plurality of support rods are provided on the welding seat, the support rods penetrate the welding seat, the support rods are slidably connected to the welding seat and are confined in the welding seat, the lower ends of the support rods are used to abut the mold groove of the lower mold, and the upper ends of the support rods are used to abut the workpiece.

[0006] By adopting the above technical scheme, a workbench is set up and a welding seat and a mounting seat are set up. By setting a lower mold on the mounting seat and a support rod on the welding seat, the shape of the support rod corresponding to the lower mold can just form the shape of the lower mold, so the workpiece can just be supported by the support rod, and when processing different workpieces, only different lower molds need to be replaced to form different shapes through the support rod, thereby improving versatility and being able to better position the workpiece. Moreover, since there are gaps between the support rods, the waste debris generated by the processing can also fall normally on the welding seat, which will not affect the subsequent production, thereby further improving the convenience.

[0007] Optionally, the transport component includes a longitudinal linear mechanism, a vertical linear mechanism, and a transverse linear mechanism. The vertical linear mechanism is installed on the longitudinal linear mechanism and moves along the longitudinal linear mechanism, and the transverse linear mechanism is installed on the vertical linear mechanism and moves along the vertical linear mechanism. The handling component and the cutting component are both installed on the transverse linear mechanism and move along the transverse linear mechanism.

[0008] By adopting the above technical solution, multi-dimensional transportation of the handling component and the cutting component can be realized, movement in three coordinate directions can be achieved, the range of movement is improved, and the accuracy of movement during handling and cutting is improved. After the handling is completed, it is only necessary to loosen the workpiece and move the handling component away, and the cutting component can then cut the product, further improving the convenience of processing.

[0009] Optionally, the transport assembly includes a transport plate and a transport cylinder, the transport plate is slidably mounted on a transverse linear mechanism, a transport frame is provided on the piston rod of the transport cylinder, and a suction cup for adsorbing the workpiece is provided on the transport frame.

[0010] By adopting the above-mentioned technical solution, the transport component can be moved flexibly on the horizontal linear mechanism. The position of the transport plate can be further adjusted by setting a transport cylinder to further ensure the precise positioning of the workpiece. At the same time, the suction cup is used to absorb the workpiece to ensure the stability and safety of the workpiece during the transport process, thereby effectively improving work efficiency and processing accuracy.

[0011] Optionally, the cutting assembly includes a cutting plate and a cutting cylinder, the cutting plate is slidably mounted on a transverse linear mechanism, a cutting head is provided on a piston rod of the cutting cylinder, and the cutting head is used to emit a laser beam and spray an inert gas.

[0012] By adopting the above technical solution, the cutting cylinder can further control the position of the cutting head, which can further improve the stability and accuracy of the workpiece control. Then, the processing can be completed by forming a laser beam through the cutting head and spraying inert gas to the processing area.

[0013] Optionally, the upper and lower ends of the support rod are both provided with deformable rubber pads, and the rubber pads can contact the welding seat when the support rod moves. The rubber pad at the upper end of the support rod is used to abut the workpiece, and the rubber pad at the lower end of the support rod is used to abut the lower mold.

[0014] By adopting the above technical solution, the rubber pads at the upper and lower ends of the support rod can play a buffering role when the support rod moves, preventing the support rod from being damaged by direct hard contact with the workpiece or the lower die. The deformation ability of the rubber pad can better adapt to workpieces of different shapes and sizes, and improve the applicability and stability of the equipment. At the same time, the rubber pad can limit the displacement of the support rod, so that the support rod cannot escape from the welding seat. When the support rod rises, the upper rubber pad can smoothly abut the workpiece, reduce the deformation or damage of the workpiece caused by the impact force, and ensure the flatness and quality of the workpiece. When the support rod descends, the lower rubber pad can smoothly abut the lower die, avoiding damage to the lower die due to rigid contact, and extending the service life of the lower die.

[0015] Optionally, a slide rail is provided in the workbench corresponding to the mounting seat, the mounting seat is slidably connected in the workbench, and a yield opening is provided in the workbench corresponding to the mounting seat, so that the mounting seat can be pulled out of the workbench.

[0016] By adopting the above technical solution, the mounting seat can slide on the slide rail, which makes it more convenient to replace the lower mold for processing. The lower mold can be taken out by simply pushing out the mounting seat.

[0017] Optionally, an electromagnet is also provided on the transport plate, and the electromagnet is used to adsorb the support rod and the lower mold.

[0018] By adopting the above technical solution, an electromagnet is directly set on the transport plate, so that all the support rods can be directly sucked upward together when the lower mold is replaced, reducing the interference between the support rods and the lower mold when replacing the lower mold, and further improving convenience.

[0019] Optionally, a limit frame is further provided on the mounting seat, the limit frame is provided around the lower mold, and the limit frame abuts against the lower mold.

[0020] By adopting the above technical solution, the limit frame can limit the position of the lower mold, thereby reducing the possibility of the lower mold escaping from the mounting seat, further improving the stability of the lower mold, and thus improving the stability of the processing.

[0021] The present application also provides an automated sheet metal laser cutting process, including the automated sheet metal laser cutting equipment described above, characterized in that it includes the following steps: a. Fix the lower mold in the mounting plate and push the mounting seat into the workbench; b. The support rod is supported by the lower die to form the shape of the workpiece; c. The transport assembly delivers the workpiece onto the support rod; d. The cutting assembly processes the workpiece; e. The workpiece and waste are sucked out together and sent out for processing to complete the production.

[0022] By adopting the above technical solution, the support plate cooperates with the lower mold to form the shape of the workpiece to support the workpiece, so that the workpiece is more stable after being supported, further improving the positioning stability of the workpiece during processing, thereby improving the processing quality.

[0023] In summary, this application has at least the following beneficial effects: 1. The present application solves the problem that laser cutting under the prior art usually adopts the method of placing the plate on the processing table, but when processing some special-shaped sheet metal parts, it is inconvenient to position the sheet metal parts each time due to the different shapes of the sheet metal parts. The present application positions the workpiece by providing a support rod that can form the bottom shape of the workpiece according to the shape of the lower mold. Compared with directly placing the workpiece in the mold for processing, the debris generated by the processing will fall into the mold and affect the stability of the mold and subsequent processing. This positioning method can isolate the debris from the mold and support the workpiece alone, which can not only improve the positioning effect of the workpiece, but also reduce the impact of the debris on the processing.

[0024] 2. The lower mold in the present application can also be replaced. Lower molds of different shapes can form a variety of different supporting shapes under the action of the support rod, thereby improving versatility.

[0025] 3. The present application also improves the convenience of replacing the lower mold by setting up an electromagnet and a slide rail, etc., which can further improve the convenience of product processing. BRIEF DESCRIPTION OF THE DRAWINGS

The workbench 1 is also provided with a transport component 4, which is used to drive the transport component 2 and the cutting component 3 to move. In specific implementation, the transport component 2 can transport the workpiece to the workbench 1 by adsorption or the like, and cut it through the cutting component 3. When laser cutting, it is only necessary to adjust the value generated by the light beam and blow gas to complete the cutting. In other embodiments, a spray pipe can also be provided to spray and cool the workpiece to reduce the deformation caused by overheating.

[0033] like Figure 1 and Figure 2 As shown, a welding seat 11 is provided on the workbench 1, a mounting seat 12 is provided on the lower side of the welding seat 11, a lower die 121 for casting a workpiece is detachably connected to the mounting seat 12, a plurality of support rods 111 are provided on the welding seat 11, the support rods 111 penetrate the welding seat 11, the support rods 111 are slidably connected to the welding seat 11 and are confined in the welding seat 11, the lower ends of the support rods 111 are used to abut against the die grooves of the lower die 121, and the upper ends of the support rods 111 are used to abut against the workpiece. In specific implementation, as Figure 2 and Figure 3 As shown in , the bottom of each support rod 111 can just fit into the lower mold 121 to form the shape in the mold groove of the lower mold 121 at the top, thereby forming the required workpiece shape, and the workpiece can be tightly supported when flipped in, thereby improving the accuracy of positioning and the convenience of positioning.

[0034] like Figure 1 and Figure 2As shown, the transport component 4 includes a longitudinal linear mechanism 41, a vertical linear mechanism 42, and a transverse linear mechanism 43. The vertical linear mechanism 42 is mounted on the longitudinal linear mechanism 41 and moves along the longitudinal linear mechanism 41, and the transverse linear mechanism is mounted on the vertical linear mechanism 42 and moves along the vertical linear mechanism 42. The transport component 2 and the cutting component 3 are both mounted on the transverse linear mechanism 43 and move along the transverse linear mechanism 43. In specific implementation, the transport component 2 and the cutting component 3 can move in three-dimensional coordinates under the drive of the transport component 4, so as to realize processing, and when the transport component 2 aligns the product, the cutting component 3 only needs to move along the transverse linear mechanism 43 to cut, which improves the convenience and accuracy of processing.

[0035] like Figure 1 and Figure 2 As shown, the transport assembly 2 includes a transport plate 21 and a transport cylinder 22. The transport plate 21 is slidably mounted on the horizontal linear mechanism 43. A transport frame 221 is provided on the piston rod of the transport cylinder 22. A suction cup 211 for adsorbing the workpiece is provided on the transport frame 221. In specific implementation, the transport cylinder 22 can further control the transport frame 221, so that the transport frame 221 can perform more precise movements, further improving the processing accuracy.

[0036] like Figure 1 and Figure 2 As shown, the cutting assembly 3 includes a cutting plate 31 and a cutting cylinder 32. The cutting plate 31 is slidably mounted on the horizontal linear mechanism 43. A cutting head 321 is provided on the piston rod of the cutting cylinder 32. The cutting head 321 is used to emit a laser beam and eject an inert gas. In specific implementation, the cutting cylinder 32 can further control the cutting head 321, so that the cutting head 321 can perform more precise movements, further improving the processing accuracy.

[0037] like Figure 1 and Figure 2 As shown, the upper and lower ends of the support rod 111 are both provided with deformable rubber pads 112. When the support rod 111 moves, the rubber pads 112 can contact the welding seat 11. The rubber pads 112 at the upper end of the support rod 111 are used to abut the workpiece, and the rubber pads 112 at the lower end of the support rod 111 are used to abut the lower mold 121. In specific implementation, the rubber pads 112 and the support rod 111 are fixedly connected by hot melting to reduce the possibility of falling. The rubber pads 112 will deform when contacting the workpiece on the upper side, and will also deform when contacting the lower mold 121 on the lower side, which can also increase friction and further improve the accuracy and effect of positioning.

In specific implementation, the mounting seat 12 can be pulled out from the clearance opening 14, thereby realizing the replacement of the lower mold 121.

[0039] like Figure 1 and Figure 2 As shown, the transport plate 21 is also provided with an electromagnet 212, which is used to adsorb the support rod 111 and the lower mold 121. The mounting seat 12 is also provided with a limit frame 122, which is arranged around the lower mold 121, and the limit frame 122 abuts against the lower mold 121. In specific implementation, the electromagnet 212 can not only assist in adsorbing the workpiece, but also can suck up the support rod 111 after the workpiece is removed, thereby improving the convenience of replacing the lower mold 121 and further improving the convenience of use.

[0040] The present application also provides an automated sheet metal laser cutting process, including the automated sheet metal laser cutting equipment described above, characterized in that it includes the following steps: a. Fix the lower mold 121 in the mounting plate and push the mounting seat 12 into the workbench 1; b. The support rod 111 is supported by the lower die 121 to form the shape of the workpiece; c. The transport component 2 delivers the workpiece onto the support rod 111; d. The cutting component 3 processes the workpiece; e. The workpiece and waste are sucked out together and sent out for processing to complete the production.

[0041] Working principle: The required lower mold 121 is first installed through the mounting seat 12, and the support rod 111 cooperates with the mounting seat 12 to form a shape for supporting the workpiece, and then the workpiece is transported to the support rod 111 for processing.
