Description

Technical Field

[0001] This utility model belongs to the field of sheet metal processing technology, specifically relating to a sheet metal cutting device and the sheet metal part. Background Technology

[0002] Laser cutting of sheet metal is an advanced process that uses a high-energy-density laser beam to cut metal sheets. With its high precision, high efficiency, and strong adaptability, it is widely used in automobile manufacturing, construction machinery, aerospace, electronic equipment and other fields.

[0003] Existing laser cutting machines typically lay sheet metal flat on the cutting table. After cutting, the sheet metal parts are collected together. However, after the entire sheet is cut, the cutting operation needs to be paused for collection. Each collection usually takes 2-5 minutes or even longer. For example, a 12kW fiber laser machine can cut 10-15 sheets per hour, but the downtime caused by collection can reach 1-2 hours per day, reducing the effective utilization rate of the equipment by 10%-15%, thereby reducing the cutting efficiency.

[0004] Therefore, a sheet metal cutting device and the sheet metal part are designed to overcome the above-mentioned technical defects. Utility Model Content

[0029] This specific embodiment is a sheet metal cutting device and the sheet metal part, the structural schematic diagram of which is shown below. Figures 1-7 As shown, the machine includes a frame 1, a guide plate 2 fixedly connected to the top surface of the frame 1, two support plates 3 fixedly connected to the top surface of the guide plate 2, a laser cutting machine 4 set on the upper side of the support plate 3, and multiple sheet metal placement plates 7 set between the two support plates 3. The top surface of the sheet metal placement plates 7 is serrated. In order to protect the sheet metal parts, movable wheels can be installed on each serrated surface to reduce friction. Two cylinders 8 are set on the lower side of each sheet metal placement plate 7 located on the top surface of the guide plate 2. The telescopic ends of the cylinders 8 are fixedly connected to the sheet metal placement plates 7.

[0030] The side walls of the sheet metal placement plate 7 are all provided with limit grooves 12. The limit grooves 12 are Z-shaped and a pusher component is provided in the limit grooves 12.

[0031] The left side of the limiting groove 12 is higher than the right side. An upward slope is set at the starting position on the right side of the limiting groove 12. Therefore, the push plate 14 is lower than the sheet metal placement plate 7 in the initial state. As the limiting groove 12 moves upward, the push plate 14 becomes higher than the sheet metal placement plate 7. This makes it easier to push the cut sheet metal parts on the sheet metal placement plate 7 to one side for discharge.

[0032] like Figure 5 and Figure 7As shown, the pushing assembly includes rollers 13 movably connected within the limiting groove 12. Mounting blocks 20 are rotatably connected to both ends of the rollers 13 on both sides of the sheet metal placement plate 7. Baffles 21 are fixedly connected to the sidewalls of the rollers 13 on both sides of the sheet metal placement plate 7. Push plates 14 are fixedly connected to the top surfaces of the mounting blocks 20. In the initial state, the push plates 14 are lower than the sheet metal placement plate 7. A transmission assembly is provided on the sidewall of the sheet metal placement plate 7, and a lifting assembly is provided between the transmission assembly and the pushing assembly.

[0033] The use of roller 13 can reduce the friction between it and the limiting groove 12, making the movement smoother and facilitating the upward or downward movement of the limiting groove 12. In addition, the use of baffle 21 can further ensure the stability and accuracy of the movement of push plate 14.

[0034] like Figure 2 and Figure 3 As shown, the transmission assembly includes sprockets 9 rotatably connected to the side wall of the sheet metal placement plate 7 near both ends, a chain 10 drivingly connecting the two sprockets 9, and a motor 11 fixedly installed on the side wall of the sheet metal placement plate 7. The output end of the motor 11 is fixedly connected to one of the sprockets 9.

[0035] The transmission method using sprocket 9 and chain 10 has high controllability and can accurately control the position of push plate 14;

[0036] Furthermore, in order to accurately control the movement position of the roller 13 within the limit groove 12, limit switches can be installed on both sides of the limit groove 12 to control the forward and reverse rotation of the motor 11, so that the motor 11 can respond quickly and further improve the level of automation.

[0037] like Figure 5 and Figure 6 As shown, the lifting assembly includes a fixing block 15 fixedly connected to the chain 10. A limit plate 16 is fixedly connected to the side wall of the fixing block 15. A slide groove 17 is provided on the side wall of the limit plate 16. One of the mounting blocks 20 is slidably connected to the slide groove 17.

[0038] like Figure 6 As shown, a positioning rod 18 is fixedly connected to the side wall of the slide 17. The positioning rod 18 passes through the mounting block 20 and is slidably connected to it. A spring 19 is sleeved on the side wall of the positioning rod 18.

[0039] The fixing block 15 can be fixed to the chain 10 with bolts. Due to the height difference of the limiting groove 12, when the roller 13 rises in the limiting groove 12, it can rise along the positioning rod 18 in the slide groove 17 through the mounting block 20. At the same time, the spring 19 is compressed. When the roller 13 falls in the limiting groove 12, the rebound of the spring 19 can cause it to fall, so as to drive the push plate 14 to rise and fall stably, further improving the stability when pushing the material.

[0040] like Figure 1 As shown, the guide plate 2 is a raised structure located between two adjacent sheet metal placement plates 7. The bottom surface of the guide plate 2 has several discharge grooves 5, and the side wall of the frame 1 is fixedly connected to a guide inclined plate 6. If the cut sheet metal parts are small, they can be directly discharged from the guide inclined plate 6 through the discharge grooves 5 when they fall during the pushing process, avoiding accumulation or residue on the cutting table.

[0041] like Figure 3 As shown, a protective plate 22 is installed on the side wall of the sheet metal placement plate 7 above the motor 11. The protective plate 22 can protect the motor 11 and prevent falling sheet metal parts from damaging the motor 11 and affecting its service life.

[0042] A sheet metal part is obtained by cutting using the aforementioned sheet metal cutting device.

[0043] Working principle: First, multiple sheet metal pieces are laid flat on the sheet metal placement plate 7, and the laser cutting machine 4 cuts the sheet metal. After a single sheet metal piece is cut, the cylinder 8 in the uncut area is activated. The cylinder 8 drives the sheet metal placement plate 7 to rise, which in turn lifts the uncut sheet metal and the cut sheet metal. However, the sheet metal placement plate 7 where the cut sheet metal part is located does not rise. Therefore, a height difference is formed between the sheet metal and the sheet metal part, and the laser cutting machine 4 continues cutting. At the same time, the corresponding electrical circuits are activated. The output shaft of the motor 11 drives the sprocket 9 to rotate. The sprocket 9 drives the fixed block 15 to move through the chain 10. The fixed block 15 drives the pushing assembly to move along the track of the limiting groove 12 through the limiting plate 16. When the roller 13 rises from the limiting groove 12, the push plate 14 pushes the sheet metal part to one side. Smaller sheet metal parts can fall directly through the discharge groove 5 and be discharged from the guide inclined plate 6. Then the motor 11 reverses and drives the pushing assembly to reset, which facilitates the next discharge and effectively improves the continuity of the operation.

[0044] All technical features in this embodiment can be freely combined according to actual needs.

[0045] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
