Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting device technology, specifically a laser cutting device for steel. Background Technology
[0002] A steel laser cutting device is an advanced piece of equipment that uses a high-power laser beam to precisely cut metal materials. Its core uses a focusing lens to concentrate the laser beam into an extremely small spot (typically 0.1-0.3 mm in diameter), generating over 10^6 W / cm². 2 With its high energy density, this technology instantly vaporizes or melts steel locally. A typical system consists of a fiber laser generator (power range 500W-30kW), a CNC motion platform (positioning accuracy ±0.05mm), an auxiliary gas system (oxygen / nitrogen, pressure 0.5-20Bar), and an intelligent control system. It can cut carbon steel from 0.5-30mm thick, with a cutting speed of up to 15m / min (taking 1mm plate thickness as an example), and a surface roughness of Ra3.2μm. Compared with traditional plasma cutting, this technology improves efficiency by 3-5 times and reduces the heat-affected zone by 60%. It is particularly suitable for complex contour processing in fields such as automobile manufacturing and precision machinery. The latest models have integrated AI real-time parameter adjustment and three-dimensional cutting functions.
[0003] The prior art application number is 202323542040.2, and the patent name is: Steel Laser Cutting Device. It includes a protective box and a fan slot. The fan slot runs through the upper surface of the protective box and is symmetrically distributed on both sides of the upper surface of the protective box. A flue gas treatment mechanism is provided on the upper part of the protective box. The flue gas treatment mechanism includes a purification box, a cover plate, an exhaust slot, an absorption fan, an adsorption plate, and filter holes. This steel laser cutting device, through the inclusion of a fume treatment mechanism, absorbs the fumes generated during laser cutting, filters and purifies them through multiple adsorption plates to meet emission standards before being released, thus preventing harmful substances in the fumes from impacting the environment and posing a health hazard to workers. The addition of an adjustment unit facilitates easier adjustment of the laser cutting head position during laser cutting, improving cutting efficiency. Simultaneously, the debris generated during cutting falls through a debris trough into a collection box for centralized collection and cleaning. However, the top-flat design of the debris trough makes it difficult for cutting debris located on both sides of the trough to slide naturally into the collection chamber, easily accumulating at the edge of the clamping platform, requiring manual intervention for cleaning and affecting continuous operation efficiency. Regarding plate fixing, the existing clamping mechanism is only optimized for right-angled plates, using a linear clamping method. When processing plates with curved edges, a gap exists between the clamp and the curved surface, reducing fixing stability and potentially affecting cutting accuracy. Therefore, a new technical solution needs to be designed to address this issue. Utility Model Content
[0004] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a laser cutting device for steel, comprising a processing chamber, a through groove on the top of the processing chamber, three partition rods fixedly connected to the inner side of the through groove, the partition rods being arranged sequentially, four mounting brackets fixedly connected to the top of the processing chamber, a longitudinal moving guide rail fixedly connected to one side of each mounting bracket, a second motor fixedly connected to one side of the longitudinal moving guide rail, one end of the power output shaft of the second motor penetrating the longitudinal moving guide rail and extending into the inner cavity of the longitudinal moving guide rail, and a second threaded rod fixedly connected to one end of the power output shaft of the second motor, via a chip collection mechanism. The device features an edge design with a rounded transition, where a partition bar in the through groove creates a continuous curved surface transition. When laser-cut debris falls, the rounded edge eliminates the dead angles where right-angled grooves accumulate, allowing the debris to slide naturally along the curved surface under gravity. This effectively collects the debris and prevents its accumulation. The clamping mechanism allows for L-shaped clamping of right-angled plates and V-shaped clamping of rounded plates, thus increasing the clamping range and expanding the device's applicability.
[0006] Preferably, a debris collection bin is fixedly connected to the bottom of the processing bin, and four mounting slots are provided on the top of the processing bin to collect debris that leaks from the through slots.
[0007] Preferably, the inner wall of the mounting groove is rotatably connected to a first threaded rod, one end of which passes through the mounting groove and extends to the outside of the processing chamber. A rotating handle is fixedly connected to one end of the first threaded rod, and the position of the fixing mechanism is adjusted by rotating the first threaded rod.
[0008] Preferably, a mounting plate is screwed to the outer side of the first threaded rod, a support frame is fixedly connected to one side of the mounting plate, and a clamping block is rotatably connected to the inner side of the support frame, and the clamping block is installed through the support frame.
[0009] Preferably, a first motor is fixedly connected to one side of the support frame, and a fixed rod is fixedly connected to one end of the power output shaft of the first motor. One end of the fixed rod passes through the two support frames, and the fixed rod is fixedly connected to the two clamping blocks. The angle of the clamping blocks can be adjusted by rotating the fixed rod.
[0010] Preferably, a transverse moving guide rail is screwed onto the outer side of the second threaded rod, and a third motor is fixedly connected to one side of the transverse moving guide rail.
[0011] Preferably, one end of the power output shaft of the third motor passes through the transverse moving guide rail and extends into the inner cavity of the transverse moving guide rail, and one end of the power output shaft of the third motor is fixedly connected to a third threaded rod, and a laser cutter is screwed to the outside of the third threaded rod to cut the plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. The laser cutting device for steel uses a chip collection mechanism with an edge design featuring a rounded transition. The continuous curved surface transition is achieved by a separator rod in the through groove. When chips generated by laser cutting fall, the rounded edge eliminates the dead corners of the right-angle groove, allowing the chips to slide naturally along the curved surface under gravity. This effectively collects the chips and prevents their accumulation.
[0014] 2. This laser cutting device for steel, through a clamping mechanism, can fix right-angled plates in an L-shaped clamping manner when it is necessary to fix them, and can rotate the clamping block 45° to a V-shaped clamping manner when it is necessary to fix rounded plates, thereby increasing the clamping range of the clamping mechanism and expanding the applicability of the device.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0022] Example 1: Please refer to again Figures 1-5 This utility model provides a laser cutting device for steel, including a processing chamber 100. A through groove 110 is formed at the top of the processing chamber 100, and three partition rods 120 are fixedly connected to the inner side of the through groove 110, arranged sequentially. A debris collection chamber 130 is fixedly connected to the bottom of the processing chamber 100. Four mounting grooves 140 are formed at the top of the processing chamber 100, and a first threaded rod 141 is rotatably connected to the inner wall of the mounting groove 140. One end of the first threaded rod 141 passes through the mounting groove 140 and extends to the processing chamber 100. On the outer side, a rotating handle 150 is fixedly connected to one end of the first threaded rod 141. A mounting plate 160 is screwed to the outer side of the first threaded rod 141. A support frame 161 is fixedly connected to one side of the mounting plate 160. A clamping block 170 is rotatably connected to the inner side of the support frame 161. A first motor 180 is fixedly connected to one side of the support frame 161. A fixing rod 181 is fixedly connected to one end of the power output shaft of the first motor 180. One end of the fixing rod 181 passes through the two support frames 161, and the fixing rod 181 is fixedly connected to the two clamping blocks 170.
[0023] Specifically, when the debris falls, it comes into contact with the separator rod 120 installed in the through groove 110. Since the separator rod 120 is cylindrical, the dividing area in the through groove 110 is rounded, so that the debris slides naturally along the curved surface of the separator rod 120 under the action of gravity and falls into the debris collection bin 130 below.
[0024] Example 2: Please refer to again Figures 1-5 Four mounting brackets 200 are fixedly connected to the top of the processing chamber 100. A longitudinal moving guide rail 210 is fixedly connected to one side of the mounting bracket 200. A second motor 211 is fixedly connected to one side of the longitudinal moving guide rail 210. One end of the power output shaft of the second motor 211 passes through the longitudinal moving guide rail 210 and extends into the inner cavity of the longitudinal moving guide rail 210. A second threaded rod 212 is fixedly connected to one end of the power output shaft of the second motor 211. A transverse moving guide rail 220 is screwed to the outside of the second threaded rod 212. A third motor 221 is fixedly connected to one side of the transverse moving guide rail 220. One end of the power output shaft of the third motor 221 passes through the transverse moving guide rail 220 and extends into the inner cavity of the transverse moving guide rail 220. A third threaded rod 222 is fixedly connected to one end of the power output shaft of the third motor 221. A laser cutter 230 is screwed to the outside of the third threaded rod 222.
[0025] Specifically, when clamping a right-angled plate, the clamping block 170 maintains a normal state and clamps and fixes the right-angled plate at an L-shaped clamping angle. When it is necessary to clamp a curved plate, the first motor 180 is started to drive the fixing rod 181 to rotate 45 degrees, so that the clamping block 170 connected to the fixing rod 181 rotates synchronously, changing the clamping angle of the clamping block 170 from L-shaped to V-shaped, so that the clamping block 170 after changing the clamping angle can stably fix the curved plate.
[0026] Working principle: When clamping a right-angled plate, the clamping block 170 maintains a normal state and clamps and fixes the right-angled plate at an L-shaped clamping angle. When it is necessary to clamp a curved plate, the first motor 180 is started to drive the fixing rod 181 to rotate 45 degrees, so that the clamping block 170 connected to the fixing rod 181 rotates synchronously, changing the clamping angle of the clamping block 170 from L-shaped to V-shaped, so that the clamping block 170 after changing the clamping angle can stably fix the curved plate.
[0027] When the debris falls, it comes into contact with the separator rod 120 installed in the through groove 110. Since the separator rod 120 is cylindrical, the dividing area in the through groove 110 is rounded, so that the debris slides naturally along the curved surface of the separator rod 120 under the action of gravity and falls into the debris collection bin 130 below.
[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
