Description

Technical Field

[0001] This utility model belongs to the field of laser cutting machine technology, specifically a laser cutting machine that is easy to load and unload. Background Technology

[0002] A laser cutting machine is an automated processing device that uses a high-energy-density laser beam to irradiate the surface of a material, causing it to melt, vaporize, or fracture rapidly, thereby achieving high-precision cutting. Compared with traditional mechanical cutting methods, laser cutting has significant advantages such as high cutting accuracy, high speed, and the ability to process complex shapes, and has become one of the key pieces of equipment for achieving efficient and high-precision material processing in modern industrial production.

[0003] However, traditional laser cutting machines still have certain limitations in their loading and unloading processes during practical applications, specifically in the following two aspects: First, the cutting area and the loading / unloading area usually overlap. Operators need to directly transport the workpiece to be processed to the cutting table and then reach into the cutting area to retrieve the workpiece after cutting. During this process, if the equipment's safety protection devices fail or personnel accidentally touch the start switch, it can easily lead to safety accidents such as laser burns or mechanical collisions. Second, loading and unloading operations must be carried out with the equipment completely stopped. After each batch of workpieces is cut, the machine must be stopped to retrieve and reload, resulting in frequent start-ups and shutdowns, significantly impacting overall production efficiency.

[0004] Therefore, it is necessary to provide a laser cutting machine with a more efficient and safer loading and unloading process. Utility Model Content

[0005] Based on this, this solution provides a laser cutting machine that facilitates loading and unloading, enabling the placement of sheet metal and the removal of workpieces in non-cutting areas, thereby improving the safety of loading and unloading operations.

[0025] Example 1

[0026] Existing laser cutting machines suffer from cumbersome loading and unloading processes, certain safety hazards, and low equipment utilization. Therefore, a laser cutting machine with easier loading and unloading has been designed. The specific solution is as follows:

[0027] like Figure 1-4As shown, a laser cutting machine that facilitates loading and unloading includes a base 1, two guide rails 2 are fixedly connected to the base 1, a common movable frame 3 is slidably connected between the two guide rails 2, multiple support rods 4 are fixedly connected to the movable frame 3, a transverse sliding structure 5 is provided on the base 1, four guide seats 8 are fixedly connected to the base 1, slide rods 9 are slidably connected to the guide seats 8, a common movable plate 6 is fixedly connected to the top of the four slide rods 9, multiple sword grids 7 are fixedly connected to the top side of the movable plate 6, and a second drive assembly 10 is installed on the base 1. The second drive assembly 10 is a telescopic cylinder, and the output end of the second drive assembly 10 is fixedly connected to the bottom side of the movable plate 6.

[0028] The multiple support rods 4 are linearly and equidistantly distributed, so the cut workpiece and the uncut sheet can be placed on the multiple support rods 4. The multiple sword grids 7 are linearly and equidistantly distributed, so the sheet can be lifted by the multiple sword grids 7.

[0029] The cross-section of the guide rail 2 is C-shaped. The two guide rails 2 can guide the movement of the moving frame 3. The two guide rails 2 are symmetrically distributed about the middle of the base 1.

[0030] Four sliding rods 9 are respectively located at the four corners of the movable plate 6. The sliding rods 9 are cylindrical structures. The sliding rods 9 slide between the four guide seats 8 respectively, which can guide the movement of the movable plate 6. The output end of the second drive component 10 is located in the middle of the bottom side of the movable plate 6. Therefore, when the output end of the second drive component 10 is extended, the movable plate 6 can be subjected to more uniform force.

[0031] The transverse structure 5 includes a rack 501 and a gear 502. Two racks 501 are fixedly connected to the top side of the moving frame 3. Two first drive components 503 are installed on the base 1. The first drive component 503 is a motor. A gear 502 is fixedly connected to the output end of the first drive component 503. The gear 502 meshes with the adjacent rack 501, so the movement of the moving frame 3 can be controlled.

[0032] The base 1 is equipped with a motion actuator 11, and a laser cutting head 12 is mounted on the motion actuator 11. The motion actuator 11 can control the movement of the laser cutting head 12, thereby realizing the cutting of the plate.

[0033] A support plate 13 is fixedly connected to the base 1, which can support the control box 14. The control box 14 is installed on the support plate 13, so the operation of the laser cutting machine can be conveniently controlled through the control box 14.

[0034] Four support legs 15 are fixedly connected to the bottom of the base 1. The four support legs 15 are located at the four corners of the bottom of the base 1. The cross-section of the support legs 15 is T-shaped, so the base 1 can be supported by the four support legs 15.

[0035] Working principle:

[0036] During use, the plate to be cut can be placed on multiple support rods 4 at the front of the moving frame 3. Then, the two first drive components 503 are started simultaneously. The output end of the first drive component 503 rotates to drive the rack 501 to move. The two racks 501 drive the moving frame 3 to move between the two guide rails 2. When the plate to be cut is in the cutting area, the rear of the moving frame 3 is in the non-cutting area. At this time, the second drive component 10 is started, and the moving plate 6 moves towards the support rod 4. Multiple sword grids 7 will pass through the gap between the two support rods 4 and lift the plate placed on the support rod 4 so that the bottom surface of the plate does not contact the support rod 4. Then, the laser cutting head 12 is controlled by the motion actuator 11 to cut the plate. At the same time as cutting, the uncut plate can be placed on multiple support rods 4 at the rear of the moving frame 3.

[0037] After the current plate is cut, the second drive assembly 10 retracts, causing the moving plate 6 to descend, so that the top of the sword grid 7 is lower than the bottom of the support rod 4. At this time, the cut workpiece is located on the support rod 4. Then, the moving frame 3 moves in the opposite direction. When the rear section of the moving frame 3 is in the cutting area, the front section of the moving frame 3 is in the non-cutting area. Therefore, while cutting the plates on the multiple support rods 4 of the rear section of the moving frame 3, the workpieces on the multiple support rods 4 of the front section can be taken out and the next plate can be placed. Therefore, not only can loading and unloading work be avoided in the cutting area, but loading and unloading can also be achieved during cutting, thereby improving the safety of loading and unloading operations and improving production efficiency.

[0038] The laser cutting machine in this solution, through the coordinated movement of the moving frame 3 and the moving plate 6, can complete the entire cycle of raw material placement, positioning, lifting and fixing, cutting, lowering and unloading without manual intervention. This shortens process changeover time, enables continuous operation, and improves equipment utilization.

[0039] Multiple support rods, acting as buffer racks, allow operators or robotic arms to pre-place the next sheet material to be cut on the rods while the machine is cutting the current sheet. Once the current sheet is cut, the moving frame immediately removes the cut workpiece and feeds in a new sheet, achieving simultaneous loading and cutting without any waiting time, thus accelerating the production pace.

[0040] Example 2

[0041] In this embodiment, the structure of the laser cutting machine is basically the same as that of Embodiment 1. The difference is that a telescopic bellows cover is added to the area of ​​gear 502 and rack 501, and a C-shaped groove component is provided on the guide rail 2. The rack 501 is placed in the groove component, and the bellows cover is placed on the groove component to prevent the debris generated by the laser cutting machine from affecting the operation of gear 502 and rack 501.
