Description

Technical Field

[0001] The invention relates to the technical field of laser cutting equipment, and in particular to a laser cutting device for aluminum alloy profiles of a refrigerated display cabinet. Background Art

[0002] For freezers, aluminum alloy profiles need to be used during the processing to ensure the strength and processing forming of the freezers. The production process of aluminum alloy profiles mainly includes three processes: melting, extrusion and coloring. Among them, coloring mainly includes: oxidation, electrophoretic coating, fluorocarbon spraying, powder spraying, wood grain transfer and other processes.

[0003] Aluminum alloy profiles need to be cut into different lengths using a cutting device during processing, but the traditional laser cutting device has a relatively simple structure. However, due to the different parameters such as the thickness of aluminum alloy profiles, the traditional laser cutting device is prone to cutting damage to the support parts supporting the workpiece during the cutting process. The support base needs to be replaced regularly, and there is no corresponding structure to handle the smoke and residue generated by the cutting process. The exhaust gas can easily damage the health of workers, and the tiny splashing residues can easily scratch the skin, reducing the use efficiency of the cutting device.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] See also Figures 1 to 8 The present invention provides a laser cutting device for aluminum alloy profiles of a refrigerated display cabinet, which includes a main frame 1, a cutting mechanism 5 for cutting a workpiece is slidably provided on the top of the main frame 1, a sliding rail 2 and a bracket 3 slidably connected to the sliding rail 2 are also provided on the top of the main frame 1, the cutting mechanism 5 is installed on the bracket 3 through a mounting seat 4 to ensure that the cutting mechanism 5 can move on the main frame 1, and the cutting mechanism 5 includes a cutting head 52, and a trigger member 51 is provided on the outside of the cutting head 52 to ensure that the trigger member 51 can move synchronously with the cutting head 52 when the cutting head 52 moves; a support seat 6 fixed on the main frame 1, and the workpiece is cut through the support seat 6 Support, the support seat 6 includes a base 63 and a plurality of support members 62 telescopically connected to the base 63. The workpiece is supported by the plurality of support members 62 to ensure the reliability of the workpiece support. When the cutting head 52 cuts the workpiece, the support member 62 corresponding to the bottom of the cutting head 52 is forced to retract into the inside of the base 63 and separate from the workpiece, ensuring that the cutting head 52 at this time will not cut the support member 62 when cutting the workpiece, thereby protecting the support member 62. After the cutting head 52 is removed, the retracted support member 62 is reset to the initial position and supports the workpiece. At this time, the workpiece can be supported to ensure that the position of the workpiece is fixed.

[0026] Preferably, a sliding hole 64 is provided on the base 63 of the present invention, the support member 62 is slidably connected to the inside of the sliding hole 64, a magnetic member 68 is provided on the support member 62, and the trigger member 51 is a magnetic body arranged corresponding to the magnetic member 68. When the magnetic body approaches the magnetic member 68, the magnetic member 68 and the magnetic body repel each other and drive the support member 62 to slide to the bottom of the sliding hole 64, and the magnetic member 68 is repelled downward by the repulsive force of the magnetic body, thereby pressing the support member 62 to move downward and press the support member 62 to the bottom of the sliding hole 64, so that the corresponding support member 62 is away from the workpiece and the cutting head 52, thereby preventing the cutting head 52 from cutting and damaging the support member 62.

[0027] In addition, a return spring 65 is provided between the support member 62 of the present invention and the bottom of the sliding hole 64. The magnetic member 68 is compressed by the repulsive force and the return spring 65 is lifted up by the return spring 65 to extend out of the sliding hole 64 when the magnetic member 68 is not repulsive. This ensures that the different positions of the magnetic body can drive the corresponding different support members 62 to extend and retract, thereby completing the control of the position of the first support member 62. A buffer hole is provided inside the support member 62. The magnetic member 68 is slidably connected to the inside of the buffer hole. A thrust spring 69 is provided between the bottom of the buffer hole and the magnetic member 68. By providing the buffer hole, it is ensured that when the magnetic body repels the magnetic member 68, the thrust spring 69 is first compressed by the magnetic member 68, so that the magnetic member 68 slides to the bottom inside the buffer hole, so that the magnetic member 68 is separated from the clamping column 67, thereby ensuring that the clamping column 67 is pulled out from the inside of the clamping hole 622, which is convenient for the subsequent sliding process of the support member 62.

[0028] Furthermore, the side wall of the support member 62 of the present invention is provided with a snap-in hole 622 connected to the buffer hole, and the base 63 is provided with a matching hole corresponding to the snap-in hole 622. The inside of the matching hole is slidably connected with a snap-in column 67. The snap-in column 67 is inserted into the inside of the snap-in hole 622 under a predetermined adjustment member so as to support and fix the support member 62. When the magnetic member 68 slides to the top of the buffer hole, the snap-in column 67 is attracted by the magnetic member 68 and snapped into the inside of the snap-in hole 622. At this time, the support member 62 is snap-in fixed in position under the action of the snap-in hole 622 and the snap-in column 67, thereby ensuring the supporting force of the support member 62 on the workpiece and preventing the supporting force of the support member 62 from being too large. Small, causing the workpiece to move downward, a tension spring 66 is provided between the clamping column 67 and the bottom of the matching hole, one end of the tension spring 66 is fixed to the bottom of the matching hole, and the other end is fixed to the clamping column 67. Through the tension spring 66, when the magnetic part 68 is separated from the clamping column 67, the clamping column 67 at this time can pull the clamping column 67 back to the bottom of the matching hole under the action of the tension spring 66, and separate the clamping column 67 from the clamping hole 622. The magnetic force between the magnetic part 68 and the clamping column 67 is greater than the elastic force of the tension spring 66, so as to ensure that when the magnetic part 68 moves to correspond to the clamping hole 622, the magnetic part 68 at this time can adsorb the clamping column 67 to the inside of the clamping hole 622 to lock the support part 62.

[0029] Better yet, the top side wall of each sliding hole 64 of the present invention is provided with a dust removal branch hole 61, and the dust removal branch holes 61 extend to a main dust removal hole. When the support member 62 is forced to slide to the bottom of the sliding hole 64, the dust removal branch hole 61 is connected with the top opening of the sliding hole 64 and suction and dust removal are performed. At this time, the cutting head 52 is subjected to a dust removal process. When the support member 62 slides to the top of the sliding hole 64, the dust removal branch hole 61 is blocked by the support member 62. At this time, the dust removal branch hole 61 no longer absorbs dust, thereby reducing energy consumption. A supporting triangle 621 is provided on the top of the support member 62, and a strip hole for the supporting triangle 621 to slide is provided on the top of the sliding hole 64.

[0030] In this embodiment, see Figures 1 to 8When in use, before cutting is performed, the magnetic member 68 moves to the top of the buffer hole under the action of the thrust spring 69, and the support member 62 moves to the top of the sliding hole 64 under the action of the reset spring 65. At this time, the clamping hole 622 corresponds to the matching hole, and the clamping column 67 overcomes the force of the tension spring 66 under the action of the magnetic member 68 and is inserted into the inside of the clamping hole 622 to lock the support member 62. Then, the workpiece is placed on the top of the support member 62, and then the cutting head 52 is controlled to cut the workpiece. At this time, when the cutting head 52 moves to the predetermined position, the magnetic body generates a repulsive force with the magnetic member 68 at the corresponding position, compressing the magnetic member 68 toward the bottom of the buffer hole, so that the magnetic member 68 is separated from the clamping column 67, and the clamping column 67 is under the tension. Under the action of the spring 66, it resets to the inside of the matching hole, and the clamping column 67 is separated from the clamping hole 622. Then, under the repulsive force of the magnetic part 68, the support part 62 is pressed to slide to the bottom of the sliding hole 64, so that the supporting triangle 621 is retracted to the inside of the strip hole. The support part 62 at this position is away from the cutting head 52, and the cutting head 52 will not damage the support part 62 during cutting. At the same time, after the support part 62 is retracted into place, the corresponding dust removal branch hole 61 is connected with the sliding hole 64 and the corresponding dust can be drawn from the strip hole into the dust removal main hole to complete the dust removal process. When the cutting head 52 mechanism moves to other positions, the support part 62 at this time is reset under the action of the reset spring 65, and the magnetic part 68 and the clamping column 67 are also reset synchronously to lock the support part 62.
