AI Technical Summary
In existing technologies, multi-angle laser cutting machines often have a lot of slag adhering to the sidewalls of the blade grid during processing, which is difficult to remove using traditional cleaning methods.
A laser cutting machine with multi-angle cutting function is adopted. By using the lifting swing component and the push-pull component, multiple alternating transverse slashes scrape against each other. The transverse slashes and swing slashes scrape off the molten slag on each other's sidewalls, thereby achieving the effect of quickly cleaning the sidewalls of the slashes.
Ensuring the smoothness of both sidewalls reduces slag adhesion during subsequent cutting, thereby extending the maintenance interval.

Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.
[0018] Please refer to Figures 1-10 The present application provides a technical solution: the laser cutting machine with multi-angle cutting function, comprising a machine tool frame 1, a plurality of transverse sword grids 33 and swing sword grids 42 are arranged in the machine tool frame 1, and the swing sword grids 42 and the transverse sword grids 33 are arranged alternately, a push-pull assembly for driving the transverse sword grids 33 to move horizontally is arranged on one side of the inner cavity of the machine tool frame 1; The top of the swing sword grid 42 and the transverse sword grid 33 is provided with a linearly arranged inverted triangular groove, so that the top of the swing sword grid 42 and the transverse sword grid 33 forms a toothed structure; The push-pull assembly is used for horizontally pushing the transverse sword grid 33 to move, so that the transverse sword grid 33 can move close to or away from a swing sword grid 42; A plurality of lifting swing assemblies for cooperating with the push-pull assembly to remove slag are arranged at the bottom of the machine tool frame 1; The swing assembly is used for driving the swing sword grid 42 to move up and down, and reciprocating swing along the longitudinal direction of the swing sword grid 42 during the up and down movement; The lifting swing assembly is composed of a lifting unit and a swing unit, the swing unit comprises L-shaped extension pieces 41 fixedly connected at both ends of the swing sword grid 42 respectively, a swing rod 46 penetratingly inserted at the bottom of the L-shaped extension piece 41, two lifting rods 43 fixedly connected on the outer wall of the bottom of the swing rod 46, a stop rod 47 fixedly connected on the outer wall of the lifting rod 43, a stop head 44 rotatably sleeved on one end of the stop rod 47 through a bearing, a horizontal plate 51 fixedly connected at the bottom of the inner cavity of the machine tool frame 1, a vertical plate 52 fixedly connected on one side of the horizontal plate 51, and a wave groove 53 slidably cooperating with the stop head 44 is arranged on the side of the vertical plate 52 away from the horizontal plate 51; The wave groove 53 is composed of a plurality of continuous V-shaped grooves in communication with each other, and a vertical positioning groove for positioning the stop rod 47 is arranged at the top of the wave groove 53; The rotatable stop head 44 reduces the friction of the stop rod 47 sliding in the wave groove 53, and makes the sliding process smooth.
[0019] In the embodiment, as Figure 5 , Figure 6 and Figure 9As shown, the lifting unit comprises a push rod motor 54 fixedly connected at the bottom of the machine tool frame 1, the output end of the push rod motor 54 is fixedly connected with a push-pull plate 55, one end of the push-pull plate 55 close to the vertical plate 52 is fixedly connected with a slide 5, the inside of the slide 5 is provided with a trapezoidal slide groove 56, the slide groove 56 is slidably connected with a sliding block 45, and the top of the sliding block 45 is fixedly connected with the bottom of the lifting rod 43; The plurality of push rod motors 54 use a PLC controller to uniformly output control signals, and through encoder feedback, the speed of each push rod is adjusted in real time and the output end is automatically reciprocated; With the up and down movement of the slide 5, the swing sword grate 42 reciprocates in the wave groove 53 through the abutment 44, and then the sliding block 45 reciprocates and swings laterally along the longitudinal direction of the slide groove 56, so that the swing sword grate 42 and the transverse sword grate 33 swing relative to each other. In the process of the transverse sword grate 33 gradually approaching the swing sword grate 42, the molten slag attached to the top and the two sides of the two is loosened and falls off due to the relative movement. After the two are attached, in the process of the swing sword grate 42 moving up and down and swinging laterally, the inverted triangular grooves on the top of the swing sword grate 42 and the transverse sword grate 33 rub against each other's side walls, so that the molten slag on the side walls is removed; The push rod motor 54 is started, the output end of the push rod motor 54 is reciprocated and retracted, the slide 5 is vertically moved up and down, and the sliding block 45 in the slide groove 56 moves together with the slide groove 56. In the process of the lifting rod 43 moving up and down, the abutment 44 will slide along the track of the wave groove 53, so that the swing sword grate 42 fixedly connected to the swing lever 46 reciprocates along the longitudinal direction of the swing sword grate 42 in the process of moving up and down. The trajectory of one end of the swing sword grate 42 is the same as the trajectory of the abutment 47 moving along the wave groove 53, so that the molten slag on the swing sword grate 42 or the transverse sword grate 33 is subjected to multi-angle friction or scraping force, improving the removal effect of the molten slag; Since the molten slag attached to the two sides of the transverse sword grate 33 and the swing sword grate 42 is irregularly shaped, as the transverse sword grate 33 and the swing sword grate 42 approach, the molten slag on the side of the two that is close to each other is gradually extruded under the friction of the approaching transverse sword grate 33 in the process of the swing sword grate 42 swinging and lifting, and the molten slag on the top and the side wall of the transverse sword grate 33 and the swing sword grate 42 is broken and loosened by mutual friction, so that it falls off. As the transverse sword grate 33 and the swing sword grate 42 approach, the inverted triangular grooves on the top of the two will scrape each other's attachment surface, so that the residual molten slag on the side wall is removed, ensuring that the attachment surface is smooth, so that the adhesion of the molten slag in the subsequent cutting process is reduced.

[0023] In the embodiment, as shown in Figure 7 and Figure 8 , a plurality of avoiding grooves 11 for avoiding the lifting rod 43 are arranged on the bottom of the inner cavity of the machine tool frame 1, and the plurality of avoiding grooves 11 are symmetrically distributed; the avoiding groove 11 is a through groove penetrating from top to bottom, and the vertical plate 52 extends downwardly through the avoiding groove 11, so that the lifting rod 43 and the resisting rod 47 are not hindered during the movement by the avoiding groove 11.
