Description

Technical Field

[0001] This utility model relates to the field of sheet metal cutting, and in particular to a serrated plate anti-slag laser cutting workbench for sheet metal processing. Background Technology

[0002] Sheet metal parts are widely used in fields such as machinery manufacturing, automotive parts, and electronic equipment housings due to their advantages such as lightweight, high strength, and easy forming. Laser cutting technology, with its high cutting precision, small heat-affected zone, and high processing efficiency, has become one of the core processes for sheet metal forming and processing.

[0003] In sheet metal laser cutting operations, to avoid the sheet metal parts to be cut from directly contacting the worktable surface, which would lead to the accumulation of cutting waste and heat deformation of the sheet metal, the industry generally uses a serrated plate as a support structure. However, when the laser cutting head performs edge contour, hole position or complex irregular structure cutting on the sheet metal parts, the laser beam can easily penetrate the sheet metal parts and act directly on the surface of the serrated plate, causing the protruding parts of the serrated plate to be melted, burned or cut off. Since the protrusions of the serrated plate are discretely distributed and there are gaps between adjacent protrusions, some slag will adhere to the top and side of the serrated protrusions due to surface tension, forming irregular slag.

[0004] Such slag not only directly damages the supporting function of the saw blade, but also has a chain of negative impacts on the entire subsequent sheet metal processing process. When the saw blade with slag supports the sheet metal to be cut, the irregular slag will cause the actual supporting surface of the saw blade to bulge, resulting in uneven contact, which in turn causes the sheet metal to be tilted or locally deformed, affecting the cutting accuracy. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a serrated plate anti-slag laser cutting workbench for sheet metal processing.

[0006] The present invention provides a serrated plate anti-slag laser cutting workbench for sheet metal processing, which adopts the following technical solution:

[0007] A slag-resistant laser cutting worktable for sheet metal processing includes a frame, a moving cutting assembly, a linkage triggering assembly, and a height-adjustable support assembly. The moving cutting assembly includes a track, a gantry frame, a laser cutting head, and sliding tables. The track is located on both sides of the top of the frame along its length. The gantry frame spans the frame and the laser cutting head is mounted on it. Two sliding tables are fixed to the bottom of both ends of the gantry frame, and the two sliding tables slide in contact with the corresponding side track. The laser cutting head is mounted on the gantry frame. The linkage triggering assembly includes two fixed blocks and rotating wheels. The components are fixed to the inner walls of two sliding tables and extend into the frame. Each fixed block is rotatably connected to a wheel. The liftable support assembly includes a connecting plate, a telescopic component, a support platform, a serrated plate, and connecting rods. There are two connecting plates, which are fixed to the inner walls of both sides of the frame. Several telescopic components are spaced apart along the length of the frame on each connecting plate. The support platform is fixed to the top of the telescopic component. The serrated plate is laid on the top of several support platforms to support the sheet metal workpiece. There are several connecting rods, which are fixed to the outer wall of each support platform. The top of the connecting rod extends to below the axis of the wheel and can abut against the wheel.

[0008] Optionally, the telescopic assembly includes a telescopic box and a spring. The telescopic box has a receiving cavity inside, the spring is disposed in the receiving cavity, the support platform abuts against the top of the spring, and the telescopic box is fixedly connected to the connecting plate at intervals along the length of the frame.

[0009] Optionally, the top of the connecting rod is provided with a contact part that adapts to the rotating wheel. The contact part is an arc-shaped surface or a spherical surface. When the rotating wheel abuts against the connecting rod, the rotating wheel and the contact part roll together to reduce frictional loss.

[0010] Optionally, the fixing block is provided with an adjustment hole extending in the vertical direction, the rotating shaft of the rotating wheel passes through the adjustment hole and slides in cooperation with the adjustment hole, and the fixing block is also provided with a locking member, which is threadedly connected to the fixing block and its end abuts against the rotating shaft to adjust the vertical height of the rotating wheel.

[0011] Optionally, the connecting plate is provided with a fixing plate, which is disposed between the support platform and the track. The fixing plate is provided with a plurality of limiting grooves, through which the connecting rod passes.

[0012] Optionally, the bottom of the connecting plate is provided with several reinforcing ribs arranged along the length of the frame.

[0013] In summary, this utility model has at least one of the following beneficial technical effects:

[0014] 1. The gantry moves along the track towards the target cutting area via the slide table, simultaneously driving the fixed block and rotating wheel inside the slide table to move in the same direction as the gantry. The outer circumference of the rotating wheel contacts the top of the connecting rod and continuously applies downward pressure. After being pressured, the connecting rod pushes the support platform downward. The support platform compresses the telescopic component, causing the support platform to move the top serrated plate downward synchronously until the serrated plate is completely separated from the bottom of the sheet metal workpiece. Through the design of temporarily moving the serrated plate downward in the cutting area, the laser beam is directly prevented from penetrating the workpiece and accidentally damaging the serrated plate, eliminating the source of slag generated by the melting of the serrated plate. There is no need for subsequent manual cleaning of slag, avoiding the impact of slag on workpiece positioning and cutting accuracy.

[0015] 2. The telescopic box design prevents the spring from shifting laterally when pressed down. The telescopic box provides vertical foundation guidance, thus ensuring that the spring will not bend or twist due to uneven force. The spring force always acts on the support platform in the vertical direction. The limiting groove on the fixed plate only allows the connecting rod to move in the vertical direction of the limiting groove, completely restricting the lateral displacement of the connecting rod. This ensures that the connecting rod is always in the limiting groove within the maximum downward stroke, maintaining displacement guidance throughout the entire process and preventing the connecting rod from tilting after it is freed from the constraint.

[0016] 3. After equipment maintenance, it may be necessary to readjust the support height of the saw blade. At this time, there is no need to disassemble the fixing block or slide table. Simply loosen the locking parts and slide the shaft along the adjustment hole to quickly adapt to the new support height, simplifying the maintenance process. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Furthermore, "several" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] This utility model discloses a serrated plate anti-slag laser cutting workbench for sheet metal processing. (See reference...) Figure 1-4 A serrated plate anti-slag laser cutting workbench for sheet metal processing includes a frame 1, a movable cutting assembly 2, a linkage triggering assembly 3, and a liftable support assembly 4. The movable cutting assembly 2 includes a track 21, a gantry frame 22, a laser cutting head, and slide tables 23. The track 21 is located on both sides of the top of the frame 1 along its length. The gantry frame 22 spans the frame 1 and is on which the laser cutting head is mounted (omitted in this utility model). There are two slide tables 23, which are respectively fixed to the bottom of both ends of the gantry frame 22. The laser cutting head is mounted on the gantry 22 and slides with the corresponding side rail 21. The linkage triggering component 3 includes a fixed block 31 and a rotating wheel 32. There are two fixed blocks 31, which are respectively fixed to the inner side wall of the two slides 23 and extend into the frame 1. A rotating wheel 32 is rotatably connected to each fixed block 31. During the cutting operation, the gantry 22 moves along the rail 21 to the target cutting area through the slides 23, and synchronously drives the fixed blocks 31 and rotating wheels 32 on the inner side of the slides 23 to move in the same direction as the gantry 22.

[0026] The liftable support assembly 4 includes a connecting plate 41, a telescopic assembly 42, a support platform 43, a serrated plate 44, and connecting rods 45. There are two connecting plates 41, which are respectively fixed to the inner walls of both sides of the frame 1. Several telescopic assemblies 42 are distributed at intervals along the length of the frame 1 on each connecting plate 41. The support platform 43 is fixed to the top of the telescopic assembly 42. The serrated plate 44 is laid on the top of several support platforms 43 to support sheet metal workpieces. There are several connecting rods 45, which are respectively fixed to the outer wall of each support platform 43. The top of the connecting rod 45 extends to below the axis of the rotating wheel 32. It can also abut against the rotating wheel 32. When the rotating wheel 32 gradually moves to the position directly above the connecting rod 45, the outer circumference of the rotating wheel 32 contacts the top of the connecting rod 45 and continuously applies downward pressure. After being pressured, the connecting rod 45 pushes the support platform 43 downward. The support platform 43 compresses the telescopic component 42, causing the support platform 43 to drive the top serrated plate 44 to move down synchronously until the serrated plate 44 is completely separated from the bottom of the sheet metal workpiece. At this time, the laser cutting head is cutting the workpiece. After the laser beam penetrates the workpiece, there is no serrated plate 44 to block it, so the serrated plate 44 will not be damaged and slag will not be generated.

[0027] When the gantry 22 moves the laser cutting head away from the area, the rotating wheel 32 disengages from the connecting rod 45. The elastic restoring force of the telescopic component 42 pushes the support platform 43 upward. The support platform 43 drives the sawtooth plate 44 and the connecting rod 45 to move upward and reset synchronously, re-engaging with the sheet metal workpiece in the subsequent area to be cut, thus restoring the support function.

[0028] The telescopic assembly 42 specifically includes a telescopic box 421 and a spring 422. The telescopic box 421 has a receiving cavity 423 inside, and the spring 422 is located in the receiving cavity 423. The support platform 43 abuts against the top of the spring 422. The telescopic box 421 is fixedly connected to the connecting plate 41 at intervals along the length of the frame 1. The connecting plate 41 is provided with a fixing plate 5, which is located between the support platform 43 and the track 21. The fixing plate 5 is provided with several limiting grooves 51, and the connecting rod 45 passes through the limiting grooves 51. The design of the telescopic box 421 can prevent the spring 422 from being fixed. When the spring 422 is pressed down, it deflects laterally. The telescopic box 421 provides vertical foundation guidance, thus ensuring that the spring 422 will not bend or twist due to uneven force. The elastic force of the spring 422 always acts on the support platform 43 in the vertical direction. The limiting groove 51 on the fixed plate 5 only allows the connecting rod 45 to move in the vertical direction of the limiting groove 51, completely restricting the lateral displacement of the connecting rod 45. This ensures that the connecting rod 45 is always in the limiting groove 51 within the maximum downward stroke, maintaining displacement guidance throughout the entire process and preventing the connecting rod 45 from tilting after it is released from the constraint.

[0029] The top of the connecting rod 45 is provided with a contact portion 451 adapted to the rotating wheel 32. The contact portion 451 is an arc-shaped surface or a spherical surface. When the rotating wheel 32 abuts against the connecting rod 45, the rotating wheel 32 and the contact portion 451 roll together to reduce friction loss.

[0030] The fixed block 31 is provided with an adjustment hole extending vertically. The shaft of the rotating wheel 32 passes through the adjustment hole and slides in cooperation with the adjustment hole. The fixed block 31 is also provided with a locking component, which is threadedly connected to the fixed block 31 and its end abuts against the rotating shaft to adjust the vertical height of the rotating wheel 32. The advantage of this design is that after equipment maintenance, it may be necessary to readjust the support height of the sawtooth plate 44. At this time, it is not necessary to disassemble the fixed block 31 or the slide table 23. It is only necessary to loosen the locking component and slide the rotating shaft along the adjustment hole to quickly adapt to the new support height, simplifying the maintenance process.

[0031] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
