Description

Technical Field

[0001] The present invention relates to the field of laser cutting, in particular to a laser cutting machine with slag treatment. Background Art

[0002] A laser cutting machine is a device that uses a laser beam to cut materials. It uses a high-energy-density laser beam to focus the laser energy into a very small area, causing the material to melt, evaporate, or burn, ultimately achieving cutting.

[0003] In order to ensure the support of the workpiece and reduce the reflection of the laser beam during the cutting process, a sword grid is usually set inside the laser cutting machine. However, in daily use, due to the adhesion of the splashing slag generated during cutting, condensed slag often appears on the surface of the sword grid. The prior art discloses a method of removing slag with a slag remover, but the slag remover requires manual operation and has low slag removal efficiency. Secondly, the slag remover is an auxiliary equipment independent of the laser cutting machine, which not only requires more space to store these devices, but also requires more expenditure to purchase the equipment. Summary of the Invention

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to 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.

[0024] Due to the adhesion of the splashing slag generated during cutting, condensed slag often appears on the surface of the sword grid. The prior art discloses a method of removing slag using a slag remover. However, the slag remover requires manual operation and has a low slag removal efficiency. Secondly, the slag remover is an auxiliary equipment independent of the laser cutting machine, which not only requires more space to store these devices, but also requires more expenses to purchase the equipment.

[0025] To resolve this issue, see Figure 1 、 Figure 2 、 Figure 3 as well as Figure 5 The laser cutting machine with slag treatment includes: an operating platform 10 and a cutting platform 30 arranged on the upper end surface of the operating platform 10.

[0026] Specifically, an inner groove 101 is provided on the upper end surface of the operating platform 10, and a plurality of sword bars 20 are detachably provided inside the inner groove 101. An inner cavity 13 is provided inside the operating platform 10, and the inner cavity 13 covers the outer side of the sword bar 20. The end of the sword bar 20 is inserted into the inner cavity 13. A rotatable synchronous belt 51 is provided inside the inner cavity 13, and a plurality of shifting bars 511 are provided on the outer side of the synchronous belt 51. When the synchronous belt 51 rotates, the shifting bars 511 continuously hit the end of the sword bar 20 inserted into the inner cavity 13.

[0027] In daily use, it is only necessary to ensure that there is at least one set of rotating synchronous belts 51 on one side. The rotation of the synchronous belt 51 will drive the pick 511 to hit the end of the sword fence 20 inserted into the inner cavity 13. In this way, when slag adheres to the sword fence 20, the slag will be shaken off by the vibration, thereby achieving the purpose of cleaning the slag on the surface of the sword fence 20.

[0028] In one embodiment, see Figure 4 The upper end surface of the operating platform 10 is provided with a plurality of slots 11 , each of which is two and symmetrically arranged at the two symmetrical edges of the inner groove 101 , and the two ends of the sword fence 20 are respectively inserted into the interior of a slot 11 .

[0029] The sword fence 20 is fixed in position by being inserted into the slot 11. This not only provides stable support during daily use, but also ensures the stability of the position of the sword fence 20 even without providing an additional fixing structure such as screws, because the workpiece is directly placed on the upper end surface of the sword fence 20.

[0030] In one embodiment, see Figure 3 and Figure 5 At least two rotating shafts 50 are provided inside the inner cavity 13, wherein the lower end of one of the rotating shafts 50 is connected to a motor (not shown in the figure), and a synchronous belt 51 is sleeved on the outside of the two rotating shafts 50. The rotating shaft 50 rotates to drive the synchronous belt 51 to rotate.

[0031] That is, the synchronous belt 1 51 is controlled to rotate by the synchronous rotation of the two rotating shafts 50. The synchronous belt 1 51 here is the same as the aforementioned technical solution, and the outer side also has a structure of a shift bar 511. The synchronous belt 1 51 in the subsequent solutions all has a shift bar 511.

[0032] In order to further enhance the vibration strength of the sword grating 20, please refer to Figure 3 and Figure 5 There are two inner cavities 13 and two synchronous belts 51, which are respectively arranged on both sides of the inner groove 101. There are four rotating shafts 50, two of which form a group. The two groups of rotating shafts 50 are respectively arranged inside the two inner cavities 13, and a synchronous belt 51 is sleeved on the outside of each group of rotating shafts 50.

[0033] The synchronous belt 51 is provided in two groups, and the two groups of synchronous belts 51 contact both ends of the sword fence 20 at the same time, so that striking vibration can be formed at both ends at the same time, thereby enhancing the vibration intensity of the entire sword fence 20, thereby avoiding some tightly attached slag.

[0034] Although vibration can remove slag well, it cannot completely remove the slag. Some stubborn slag will still adhere to the sword grating 20. In order to further remove these stubborn slag, please refer to Figure 3 and Figure 5, on both sides of the inner groove 101 perpendicular to the synchronous belt 51, moving grooves 12 are opened, and a slag pushing plate 40 is clamped inside the moving grooves 12. The slag pushing plate 40 moves along the moving grooves 12 to push off the molten slag on the surface of the sword grid 20.

[0035] That is, an additional movable slag pushing plate 40 is provided. After processing, the molten slag attached to the surface of the sword grid 20 can be cleaned by pushing the slag pushing plate 40.

[0036] To further strengthen the linkage between the slag pushing plate 40 and the first synchronous belt 51, please refer to Figure 3-Figure 6 , the inner cavity 13 is a groove with a square shape in cross-section. Four rotating shafts 50 are arranged at the four corners of the inner cavity 13. The moving grooves 12 are connected to the inner cavity 13. The first synchronous belt 51 is arranged in two parallel cavities of the inner cavity 13. Inside the two cavities of the inner cavity 13 perpendicular to the first synchronous belt 51, a second synchronous belt 52 and a connecting bar 53 are provided. The second synchronous belt 52 is sleeved on the two rotating shafts 50. The two ends of the connecting bar 53 are respectively fixed on the outer sides of the two rotating shafts 50. The two ends of the slag pushing plate 40 have insertion blocks 41 inserted into the inside of the moving grooves 12. Clamping plates 521 are provided on the inner side walls of the second synchronous belt 52 and the connecting bar 53, and the clamping plates 521 are fitted to both sides of the insertion blocks 41.

[0037] That is, two driving methods, horizontal and vertical, are formed through the four rotating shafts 50. Although the horizontal first synchronous belt 51, the vertical second synchronous belt 52, and the connecting bar 53 are all driven to rotate by the two rotating shafts 50, the clamping plates 521 provided on the adjacent sides of the second synchronous belt 52 and the connecting bar 53 are movable in the same direction as the clamping plates of the connecting bar 53 itself. This method constitutes the basic condition for controlling the simultaneous movement of both ends of the slag pushing plate 40. With the synchronous drive of the four rotating shafts 50, when the first synchronous belt 51 rotates in the same direction to drive the stripping bar 511 to strike the end of the sword grid 20, the two groups of clamping plates 521 will move in the same direction. At this time, the slag pushing plate 40 moves unidirectionally along the moving grooves 12. After the slag pushing plate 40 moves to the other end of the moving grooves 12, the four rotating shafts 50 rotate in the reverse direction to form a reciprocating motion, ensuring vibration while also being able to control the slag pushing plate 40 to reciprocally extrude the molten slag, greatly improving the cleaning efficiency and cleaning effect of stubborn molten slag.

[0038] To further facilitate the cleaning of molten slag, please refer to Figure 3 , on one side of the bottom of the inner groove 101, a slag discharge groove 14 penetrating the operation platform 10 is opened.

[0039] The fallen molten slag will enter the bottom of the inner groove 101, and the accumulated molten slag in the inner groove 101 can be cleaned from the slag discharge groove 14.

[0040] Based on the setting of the slag discharge groove 14, please refer to Figure 3A draw plate 15 is further provided inside the slag unloading chute 14 in a pull-out manner.

[0041] In this way, when the slag is vibrated or pushed away, it will directly fall on the upper end surface of the drawer plate 15. When cleaning, the drawer plate 15 can be directly pulled out to complete the cleaning, which is simple to operate. In addition, the drawer plate 15 can also be set to a drawer-type structure.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
