Description

Technical Field

[0001] The invention relates to the technical field of sheet metal production equipment, in particular to a sheet metal laser cutting machine. Background Art

[0002] Laser cutting machine is an industrial equipment that uses high-energy laser beams to cut materials accurately and quickly. In sheet metal processing, its high precision, high efficiency and non-contact processing characteristics make it the preferred equipment in the sheet metal processing industry.

[0003] Since the laser cutting machine melts the cut part of the sheet metal at high temperature during sheet metal processing, slag is generated at the cut part and flows downward. In order to reduce the possibility of the slag recooling and solidifying on the lower surface of the metal, thereby causing the sheet metal to be lifted up by the slag and tilted, the processing platform of the existing laser cutting machine is provided with several rows of steel bars with prismatic protrusions on the upper surface, so that several triangular pieces on the steel bars support the sheet metal in a point contact manner, thereby effectively reducing the probability of the generated slag flowing to the contact position between the sheet metal and the processing platform.

[0004] However, it is found in actual production that since the formation of slag is often accompanied by sputtering, after multiple processing by the laser cutting machine, slag is still easily attached to the triangular pieces. The existing technology usually uses a slag remover to fit the two sides of the triangular pieces, and manually pushes the slag remover to clean the slag. However, since the slag remover needs to rely on the support of steel bars to operate, the angle for cleaning the slag is also limited by the length direction of the steel bars, resulting in insufficient slag cleaning effect on the adjacent end faces of the triangular pieces in each row.

[0005] In view of the above problems, a technical solution of a sheet metal laser cutting machine is proposed. Summary of the invention

Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments.

[0019] A sheet metal laser cutting machine, such as Figure 1 , Figure 2 as well as Figure 3 As shown, it includes a frame 1, a space for stacking or transferring waste is reserved in the middle of the frame 1, a track and a gantry structure that can slide along the track are arranged on the frame 1, a cutting machine head is installed on the gantry structure, a platform seat 2 in a mouth-shaped structure is fixedly arranged on the inner side of the frame 1, a plurality of longitudinally arranged T-shaped bars are fixedly welded on the platform seat 2 at intervals, a plurality of support sheets 4 arranged in a transverse interval are fixedly arranged on the platform seat 2 through the plurality of T-shaped bars, a plurality of convex ridge sheets 5 are integrally formed on the support sheet 4, and the vertical section of the convex ridge sheet 5 is triangular, so that when the sheet metal is placed on the plurality of support sheets 4, it is supported by the ends of the plurality of convex ridge sheets 5, and the contact area is small; Two electric winches 10 and steel strands 9 with one end respectively wound by the two electric winches 10 are arranged on the platform seat 2, wherein the electric winches 10 are distributed at both ends of the support plate 4. In the embodiment, there is only one group of steel strands 9 according to the structure of the electric winches 10, and there are two steel strands 9 in the group, that is, one end of the two steel strands 9 are wound by an electric winch 10 at the same time, and the two electric winches 10 can tighten the steel strands 9 until the two steel strands 9 both abut against the surfaces of a plurality of convex ridge sheets 5, that is, the steel strands 9 are manufactured by twisting a plurality of thin steel ropes to form a regular alternating curved surface on the surface thereof, so that when the steel strands 9 slide against the surface of the convex ridge sheet 5, the depression on the surface thereof can be used to guide the slag attached to the surface of the convex ridge sheet 5 to separate from the convex ridge sheet 5.

[0020] like Figure 4 as well as Figure 5As shown, in order to increase the contact area between the steel strands 9 and the surface of the convex rib piece 5, the side edges of the convex rib piece 5 are formed with transition surfaces 501 that connect the end surfaces on both sides of the side edges. The transition surfaces 501 are used to reduce the influence of the thickness of the convex rib piece 5 on the cleaning effect of the steel strands 9. In this embodiment, the convex rib piece 5 has a 180-degree central symmetrical structure, and the two steel strands 9 are S-shaped and staggered along the adjacent convex rib pieces 5 on a support piece 4. That is, in this embodiment, each steel strand 9 can fit a transition surface 501 on each convex rib piece 5. In order to make the steel strands 9 fit more closely to the adjacent side surfaces of the convex rib piece 5, the convex rib piece 5 is formed on both sides of the triangular cross-section into an arc surface structure that is concave toward the convex rib piece 5.

[0021] like Figure 1 , Figure 2 as well as Figure 3 As shown, for the driving mode of the electric winch 10, a two-way motion mechanism connected to the electric winch 10 is provided in this embodiment. Specifically, the two-way motion mechanism includes a sliding component that drives each group of steel strands 9 to slide close to the next support sheet 4, and a lifting component that drives the steel strands 9 to slide along the height direction of the convex rib sheet 5. The lifting component is used to realize that the two steel strands 9 are separated from the convex rib sheet 5, and the steel strands 9 can be adjusted in the height direction of the convex rib sheet 5, thereby changing the position of the steel strands 9 against the convex rib sheet 5. In order to keep the two steel strands 9 entangled when switching to the next support sheet 4, the present application provides a shaping component. The shaping component slides the same length along the same sliding direction when the sliding component drives the steel strands 9 to slide, that is, the shaping component is used to keep the steel strands 9 in the state before leaving the convex rib sheet 5 each time they are separated from the convex rib sheet 5, thereby improving the degree of automation of cleaning; Among them, in order to reduce the slag debris that may be stuck on the steel strand 9, the outer diameter of the guide bar 11 gradually increases from the position close to the end of the convex ridge piece 5, and a plurality of cleaning grooves 111 are opened on the peripheral side of the guide bar 11, that is, under the action of the lifting component, when the guide bar 11 moves up, it drives the recessed position on the surface of the steel strand 9 to stay at the notch of the cleaning groove 111, and then the sliding component guides the recess of the steel strand 9 to reciprocate and abut the notch edge of the cleaning groove 111. Since the operating speed of the electric winch 10 can be kept constant, the steel strand 9 can vibrate with the same frequency, thereby shaking off the slag debris in the recess of the steel strand 9 through the notch of the cleaning groove 111.

[0022] like Figure 1 , Figure 2 as well as Figure 3As shown, the electric winch 10 is fixedly arranged in the mounting seat 3, the sliding assembly includes two groups of screw rods 8, sliding rods 7, drive motors 16 and two connecting seats 6 supported by the lifting assembly distributed on both sides of a plurality of support plates 4, the mounting seat 3 is slidably sleeved on the screw rods 8 and the sliding rods 7, the drive motor 16 is fixedly arranged on a connecting seat 6, one end of the screw rod 8 is fixedly connected to the output end of the drive motor 16, and the other end of the screw rod 8 is rotatably arranged on another connecting seat 6, both ends of the sliding rod 7 are fixedly connected to the connecting seat 6, and the lifting assembly includes two groups of pushing members 15 that maintain a relative position with the ground, and the pushing members 15 are used to push the sliding seat to slide and position.

[0023] like Figure 5 As shown, since there will inevitably be slag at the end of the convex rib sheet 5, the shaping component needs to be as close to the end of the convex rib sheet 5 as possible, and the steel strand 9 is fed from the shaping component to the plurality of convex rib sheets 5. The frame 1 is provided with an abutment component, which is used to change the distance between the shaping component and the end of the convex rib sheet 5 when the shaping component slides, and can make the shaping component elastically abut the end of the convex rib sheet 5. Specifically, the shaping component includes a placement box 12 and a plurality of guide bars 11 distributed in an array. The guide bars 11 slide out of the placement box 12 from the placement box 12 toward the convex rib sheet 5, and guide The cross-sectional width of the end of the strip 11 slidingly abutting the convex ridge piece 5 is less than or equal to the width of the convex ridge piece 5 in the same direction. The abutting assembly includes two undulating members 13 fixedly connected to the frame 1 and a spring 14 sleeved on the guide strip 11. The two undulating members 13 are symmetrically distributed on both sides of a number of support sheets 4. The placement box 12 is formed with a contact member 121 in contact with the upper surface of the undulating member 13. The upper surface of the undulating member 13 is formed into a wavy structure, and a number of troughs of the wavy structure correspond to the positions of a number of convex ridge pieces 5. The two ends of the spring 14 are in contact with the placement box 12 and the guide strip 11 respectively.

[0024] like Figure 6 As shown, since dust is also generated when the steel strand 9 scrapes the slag, in order to reduce the impact of dust on the factory environment, a water storage chamber 122 is arranged in the placement box 12, and the guide strip 11 is provided with a water inlet hole 112 connecting the water storage chamber 122 with the outside, and one end of the water inlet hole 112 can be aligned with the end of the convex rib piece 5. The water in the water storage chamber 122 can be drawn out from the water storage chamber 122 every time the steel strand 9 leaves the convex rib piece 5 through a negative pressure mechanism connected by a pipeline, thereby ensuring efficient use of water used for dust reduction.

[0025] Usage: During pre-installation, two steel strands 9 can be overlapped and wound around any row of convex ridges 5 in an 8-shaped structure, and then both ends of the steel strands 9 are connected to the electric winch 10, and then the electric winch 10 is started to tighten the two steel strands 9, and then the two-way motion mechanism can be used to take the two steel strands 9 away from the working area of ​​the cutting machine head; When the laser cutting machine stops cutting sheet metal or other objects, the electric winch 10 can be transferred to one end of several rows of support plates 4 through a two-way motion mechanism, and the two steel ropes 9 can be reciprocated from top to bottom one by one and simultaneously perform reciprocating motion, so that some debris on the convex ridge plate 5 can be effectively cleaned.

[0026] Beneficial effect: Two electric winches 10 are used to tighten several groups of steel strands 9, and then they are pulled separately, so that the steel strands 9 tend to be straightened to stick to the convex ridge piece 5, so that the cleaning effect of the convex ridge piece 5 is improved. The cleaning rate and effect of the convex ridge piece 5 are significantly better than the cleaning of conventional tools currently used.
