Description

Technical Field

[0001] The invention relates to the technical field of steel section processing, in particular to steel section laser cutting equipment. Background Art

[0002] Steel sections (such as H-shaped steel, I-shaped steel, channel steel, etc.) are widely used in construction, bridges, machinery manufacturing, shipbuilding and other fields. In the production process of steel sections, laser cutting machines are used to perform customized processing such as high-precision cutting and complex contour cutting on the steel sections. The high-power density laser beam irradiates the steel sections, heating the material to the vaporization temperature and evaporating to form holes. As the light beam moves, the holes continuously form a very narrow slit to complete the cutting of the steel sections.

[0003] When the existing laser cutting machine cuts H-shaped steel, the H-shaped steel is placed on the cutting table through a metal pad, which is mainly used to raise and support the H-shaped steel so that the laser cutting head can cut the H-shaped steel at multiple angles. The top of the metal pad contacts the H-shaped steel through a toothed structure to reduce the contact area with the H-shaped steel, reduce heat conduction, and prevent the steel from sliding. However, when the current laser cutting head cuts H-shaped steel, the laser beam still carries energy after penetrating the steel. When it irradiates the pad, it will cause a small degree of melting and damage to the pad. This This kind of melting and damage will leave irregular cutting marks on the top of the tooth structure of the pad. After repeated accumulation, the flatness of the pad will change, and this change is difficult for personnel to detect, especially in long-term steel cutting work. In the subsequent steel cutting, the uneven pad cannot guarantee the accurate positioning of the steel, and the cutting accuracy of the laser cutting head will also be affected. The position of the pad is adjusted in advance to avoid the position to be cut, which increases the complexity of the processing operation. Faced with the processing requirements of different cutting positions, frequent adjustment of the pad position not only increases labor costs, but also reduces production efficiency. Summary of the invention

[0004] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide a steel section laser cutting equipment to solve the problem that the steel section support structure is easily damaged by the laser cutting head in the current steel section laser cutting machine mentioned in the above-mentioned background technology, resulting in unevenness affecting the support flatness.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a steel laser cutting device, comprising a main component group, the main component group comprising a steel part, a laser cutting head, a main cross arm, a main vertical arm and a bottom guide rail seat, the laser cutting head is used to cut the steel part, the bottom guide rail seat is installed on the ground, the main vertical arm and the main cross arm are used to slide on the bottom guide rail seat, a movable support component group is arranged at the bottom of the steel part, the movable support component group is used to support the steel part to be cut at a position as the laser cutting head moves, the movable support component group comprises an outer connecting arm and a dynamic support assembly, the dynamic support assembly comprises a lower cross frame, an adjusting button is arranged on the side of the lower cross frame, the adjusting button is connected to a screw rod, the outside of the screw rod is connected to a movable frame through a nut pair, a support wheel 1 is installed on the movable frame, side plate frames are connected to the two sides of the lower cross frame, support wheels 2 are installed on the side plate frames, The locking plate assembly comprises a U-shaped guide frame, a movable support plate is provided on the side of the U-shaped guide frame, a guide wheel is installed on the movable support plate, and the bottom of the movable support plate is in sliding contact with the lower support frame.

[0009] Preferably, the end tripod is connected to the transverse support frame, the movable plate is in sliding contact with the guide frame rod through a slide groove, and one end of the guide frame rod is connected to the bottom pressure plate.

[0010] Preferably, the spring member is connected between the L-shaped connecting arm and the bottom pressure plate, a toothed structure is provided on the top of the lower support member, and the lower support member is used to contact the bottom of the main component group through the toothed structure.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The support structure can move with the movement of the laser cutting head. The support points of the cutting position are always located on both sides of the cutting position. This method avoids the laser beam from directly irradiating the support structure, thereby preventing the support structure from being melted and damaged by the laser. This ensures that the support structure can accurately and stably support the steel parts in long-term use, thereby improving the cutting accuracy.

[0015] 2. The traditional method requires frequent manual adjustment of the pad position to avoid direct laser beam irradiation of the pad, which not only increases the complexity and time cost of the operation, but also requires additional manual intervention. The support structure design automatically follows the movement of the laser cutting head, eliminating the need for frequent manual adjustments, thereby reducing the complexity of the operation and improving the processing efficiency.

[0016] 3. Fixed support components and locking frame components are provided at positions where the steel profiles are not cut or where the cutting is completed. When the fixed support components support the steel profiles, the dynamic support components can be avoided when the dynamic support components move over. After the dynamic support components move over, the steel profiles will be supported again. The locking frame components are used in conjunction with the dynamic support components. When the dynamic support components are about to overlap with the fixed support components at the current position, the locking frame components will release the support for the fixed support components, allowing the fixed support components to avoid the dynamic support components. After the dynamic support components move away, the fixed support components will be supported in conjunction with each other to ensure the stability of the fixed support components in supporting the steel profiles.

[0033] The vertical truss 229 is connected to the transverse truss 228 and the side panel frame 226. Two external connecting arms 21 are provided, and the two external connecting arms 21 are symmetrically distributed on both sides of the lower transverse frame 221. One end of the external connecting arm 21 is connected to the vertical truss 229 and the transverse truss 228 through a groove, and the other end of the external connecting arm 21 is connected to the main vertical arm 14.

[0034] The end tripod 311 is connected to the transverse support 228 , the movable plate 314 is in sliding contact with the guide frame rod 315 through a slide groove, and one end of the guide frame rod 315 is connected to the bottom pressure plate 319 .

[0035] The spring member 318 is connected between the L-shaped connecting arm 316 and the bottom pressure plate 319 . A tooth structure is provided on the top of the lower support member 317 , and the lower support member 317 is used to contact the bottom of the main component group 01 through the tooth structure.

[0036] The U-shaped guide frame 321 is connected to the end tripod 311, and the U-shaped guide frame 321 is connected to the vertical truss 229 through a bracket. The bottom of the U-shaped guide frame 321 is in sliding contact with the movable support plate 322. Two guide wheel members 323 are provided, and the two guide wheel members 323 are provided on both sides of the movable support plate 322. The guide wheel members 323 are in contact with the side surfaces of the U-shaped guide frame 321.

[0037] The lower support frame 324 is connected to the bottom pressure plate 319 , and both sides of the U-shaped guide frame 321 are provided with beveled edges.

[0038] Working principle: the outer connecting arm 21 is connected between the main vertical arm 14 and the dynamic support assembly 22. When the main vertical arm 14 moves, the dynamic support assembly 22 will be driven to move together through the outer connecting arm 21, so the mobile support component group 02 will be supported vertically below the laser cutting head 12 and the steel part 11. The support wheel 1 225 in the dynamic support assembly 22 supports the bottom of the contact steel part 11, and the support wheel 2 227 supports the side of the contact steel part 11. When the laser cutting head 12 cuts the steel part 11, the two sides of the position to be cut are supported by the support wheel 1 225. After cutting at the current position, the laser cutting head 12 moves forward, which will drive the dynamic support assembly 22 to move forward together, so the support wheel 1 225 will always be supported on the steel part 11. On both sides of the position to be cut, the laser generated by the laser cutting head 12 will not irradiate the support wheel 1 225 and the support wheel 2 227, avoiding the unevenness of the support structure caused by laser irradiation, and by rotating the adjusting knob 222, the movable frame 224 is driven to move on the lower cross frame 221 by driving the screw rod 223 to rotate, so that the size of the steel sections 11 of different widths can be adapted; the support of the position to be cut is supported by the dynamic support assembly 22 to ensure the cutting stability, and the position where the cutting is completed or not is supported by the fixed support component group 03. The support of the fixed support component group 03 is achieved by the contact between the toothed mechanism of the lower support member 317 and the bottom of the steel section 11, such as Figure 1 In the position shown, the laser cutting head 12 will move to the left after cutting the current position of the steel part 11. The movement is through the moving mechanism on the main vertical arm 14, which allows the main vertical arm 14, the main horizontal arm 13 and the laser cutting head 12 to slide on the bottom guide rail seat 15. In the moving support component group 02 that is driven to move together, the end tripod 311 and the pressure wheel 312 connected to the side of the cross frame 228 will also move, and the pressure wheel 312 will contact the inclined rail frame 313. When the laser cutting head 12 moves forward, the pressure wheel 312 will be separated from the current The inclined rail frame 313 at the first position will contact the inclined rail frame 313 at the next position, and then it will contact the inclined rail frame 313 at the next position. As the pressure wheel 312 continues to move forward, it will squeeze the inclined rail frame 313 and the movable plate member 314 downward, and the movable plate member 314 will slide downward in the guide frame rod 315 through the slide groove, and the spring member 318 will accumulate force and shrink. Then the movement of the movable plate member 314 will drive the lower support member 317 to move through the L-shaped connecting arm 316, so that the toothed structure of the lower support member 317 will be out of contact with the bottom of the steel member 11, so as to achieve the purpose of avoiding the movable support assembly 22. Figure 7As shown in the figure, the lower support member 317 which is in the same position as the dynamic support assembly 22 will avoid the dynamic support assembly 22 and be squeezed to the bottom of the dynamic support assembly 22, while the lower support member 317 which is not in the same position as the dynamic support assembly 22 will still contact the bottom of the steel member 11 through the tooth structure to support other parts of the steel member 11. After the pressure wheel 312 is no longer in contact with the current inclined rail frame 313, the spring member 318 will release the stored force to reset the dynamic plate member 314 and the inclined rail frame 313 due to the lack of pressure from the pressure wheel 312, thereby driving the lower support member 317 to contact the bottom of the steel member 11 through the tooth structure again. The locking frame assembly 32 in the technical support component group 03 is determined. Before the pressure wheel 312 and the inclined rail frame 313 at the next position are about to contact, the U-shaped guide frame 321 connected to the side of the end tripod 311 and the vertical truss 229 will contact the guide wheel member 323 through the inclined surface. As the U-shaped guide frame 321 moves forward, the guide wheel member 323 will be pushed to the side, and the tension spring connected between the movable support plate 322 and the lower support frame 324 will accumulate force and stretch, and the guide wheel member 323 will drive the movable support plate 322 to move, and the movable support plate 322 will slide on the slide groove of the lower support frame 324. At this time, the movable support plate 322 will release the contact with the bottom of the movable plate member 314, and then as the movable support When the support assembly 22 moves forward, the movable plate 314 will not be blocked by the passive support plate 322 when it moves downward. After the pressure wheel 312 is no longer in contact with the inclined rail frame 313 at the current position, the inclined rail frame 313 will reset, and the U-shaped guide frame 321 will also release the contact with the guide wheel member 323, so that the tension spring between the movable support plate 322 and the lower support frame 324 releases the stored force, and pulls the movable support plate 322 to reset, and the movable support plate 322 will contact the bottom of the movable plate member 314. In this design, when the lower support member 317 that does not overlap with the movable support assembly 22 contacts the bottom of the steel member 11 through the toothed structure for support, the weight of the steel member 11 is supported by the lower support 317, the L-shaped The connecting arm 316 and the movable plate 314 will transfer the weight to the movable support plate 322 at the bottom of the movable plate 314, and the movable support plate 322 will then transfer the weight to the lower support frame 324 at the bottom and then to the bottom pressure plate 319, thereby improving the stability of the lower support member 317 supporting the steel section 11. When there is no locking frame assembly 32, the support of the lower support member 317 to the steel section 11 requires the support of the spring member 318. However, when facing a heavier steel section 11, the spring member 318 cannot guarantee the stability of the support for the steel section 11. There are multiple fixed support component groups 03, which are evenly distributed at the bottom of the steel section 11 to support the steel section 11.

[0039] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
