Description

Technical Field

[0001] This utility model relates to the field of cutting devices, specifically to a steel plate flame cutting machine. Background Technology

[0002] Flame cutting is a common method for rough machining of steel plates. During flame cutting, molten slag is generated. If this slag is not treated promptly or properly, it will directly affect production efficiency, pollute the environment, and even waste resources.

[0003] In the prior art, utility model patent application number CN202421273478.7 discloses a flame cutting auxiliary device, including a slag water tank with a filter plate inside. Lifting mechanisms are provided on both sides of the upper end of the slag water tank. Each lifting mechanism includes a winding wheel base with a winding wheel inside, and a winding rope is wound on the winding wheel. One end of the winding wheel is connected to a motor. Sliding strips are provided at the corners of the inner side of the slag water tank, and grooves are formed on the sliding strips. The filter plate is slidably connected to the grooves of the sliding strips, and the end of the winding rope is fixed to the filter plate. During flame cutting, slag falls into the slag water tank, cools and solidifies upon contact with water, and is trapped on the filter plate. The winding rope drives the filter plate upward, removing the slag from the cooling water for cleaning and recycling.

[0004] Although the aforementioned flame cutting auxiliary device can remove molten slag from the cooling water by moving the filter plate upwards, it is inconvenient to clean and recycle the molten slag trapped on the filter plate because both the molten slag tank and the filter plate are located below the flame cutting machine, and the filter plate cannot be removed from the molten slag tank. This needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a steel plate flame cutting machine that facilitates the removal of the filter tray for cleaning molten slag, thereby addressing the deficiencies mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A steel plate flame cutting machine includes a long, narrow frame on which multiple grid plates for supporting the plate to be cut are fixedly mounted. Above the grid plates, a gantry frame, driven by a drive mechanism and moving along the length of the frame, is mounted on the frame. A flame cutting mechanism is mounted on the gantry frame. Below the grid plates, a movable frame, driven by a drive assembly and moving along the length of the frame, is mounted on the frame. A cooling water tank is fixedly mounted inside the movable frame. A filter tray is located inside the cooling water tank, and multiple filter holes are evenly distributed on the bottom wall of the filter tray. A lifting plate, driven vertically by a telescopic component, is located inside the cooling water tank. A support plate for supporting the bottom of the filter tray is fixedly mounted on the lifting plate.

[0008] As a preferred technical solution, a slide rod extending along its length is fixedly installed on the frame, and a sliding sleeve matching the slide rod is fixedly installed on the movable frame; the driving mechanism includes a lead screw driven to rotate by a drive motor, the lead screw is arranged parallel to the slide rod, and a lead screw nut matching the lead screw is fixedly installed on the movable frame.

[0009] As a preferred technical solution, both the cooling water tank and the filter tray are elongated strips extending along the width of the frame; two lifting plates are provided, and the two lifting plates are respectively located at both ends of the length direction of the cooling water tank.

[0010] As a preferred technical solution, the lifting plate is attached to the side wall of the cooling water tank, and a vertically extending guide ridge is fixedly installed on one side of the lifting plate. The inner wall of the cooling water tank is provided with a guide groove that matches the guide ridge.

[0011] As a preferred technical solution, the telescopic component includes a cylinder installed on the outside of the cooling water tank, the piston rod of the cylinder extending upward, the upper end of the lifting plate extending out of the outside of the cooling water tank, and a fixing seat fixedly installed on one side of the upper end of the lifting plate, the fixing seat being fixedly installed on the piston rod of the cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This application uses a drive motor to drive a lead screw to rotate. The lead screw acts on a lead nut and drives the movable frame and cooling water tank to move synchronously with the gantry frame, so that the cooling water tank is kept directly below the gantry frame. The cooling water tank collects the molten slag produced by the flame cutting head cutting the plate, thereby preventing the molten slag from falling to the ground and being inconvenient to clean.

[0014] This application uses a telescopic component to lift the lifting plate and the pallet, which in turn lifts the filter tray and moves it outside the cooling water tank. The filter tray is used to retrieve the molten slag that has fallen into the cooling water tank. The filter tray can then be removed from the top of the two pallets to empty the molten slag, making the cleaning and recycling of the molten slag more convenient. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, a steel plate flame cutting machine includes a frame 1, which is an elongated strip extending front to back. The frame 1 includes a rectangular frame 3, and support legs 4 are fixedly installed at the four bottom corners of the frame 3. Multiple grid plates 5 for supporting the plate to be cut are welded or fixedly installed inside the frame 3. The grid plates 5 are elongated strips extending along the length of the frame 1, and the multiple grid plates 5 are evenly spaced left and right along the width of the frame 1. The tops of the multiple grid plates 5 are flush.

[0023] A gantry frame 6, driven by a drive mechanism and moving back and forth along the length of the frame 1, is mounted on a frame 1 above multiple grid plates 5. The gantry frame 6 is equipped with a flame cutting mechanism. Specifically, the gantry frame 6 includes a horizontally extending beam, with vertically extending columns bolted to its left and right ends. An electric slide block 7 is bolted to the lower end of each column. Guide rails 8, matching the electric slide block 7, are bolted to the left and right sides of the top of the frame 3. The guide rails 8 extend back and forth along the length of the frame 1. In use, the material to be cut is placed on top of the multiple grid plates 5. The electric slide block 7 drives the gantry frame 6 to move back and forth along the guide rails 8. During the movement of the gantry frame 6, the flame cutting mechanism cuts the material.

[0024] like Figure 2 As shown, the bottom of the crossbeam of the gantry 6 is provided with a transverse groove 9. A slider 10 is slidably installed in the groove 9. The lower end of the slider 10 extends out of the groove 9 and is fixedly mounted with a mounting plate 11 by bolts. An adjusting cylinder 12 is bolted to the mounting plate 11. The piston rod of the adjusting cylinder 12 extends downward and is fixedly mounted with a mounting bracket 13 by bolts. A flame cutting head 14 is fixedly mounted on the mounting bracket 13. The flame cutting head 14 is used to cut the plate. An adjusting motor 15 is bolted to one end of the groove 9. A lead screw 16 extending in the same direction as the groove 9 is fixedly mounted on the motor shaft of the adjusting motor 15 by a coupling. The end of the lead screw 16 away from the adjusting motor 15 is rotatably connected to the inner wall of the groove 9 by a bearing. The slider 10 is threadedly connected to the lead screw 16. The adjusting motor 15 drives the lead screw 16 to rotate, and the lead screw 16 drives the slider 10 to move left and right along the groove 9, thereby adjusting the cutting position of the flame cutting head 14 on the plate.

[0025] like Figure 3 As shown, a movable frame 17, driven by a drive assembly and moving back and forth along the length of the frame 1, is mounted on a frame 1 located below multiple grid plates 5. The movable frame 17 is a rectangular frame, and a cooling water tank 18 containing cooling water is bolted to the inside of the movable frame 17. A slide rod 19 extending back and forth along the length of the frame 1 is bolted between the two support legs 4 on the left side. A sliding sleeve 20 matching the slide rod 19 is bolted to the left end of the movable frame 17, providing support and guidance for the back and forth movement of the movable frame 17. The drive mechanism includes a lead screw 21 rotatably mounted between the two support legs 4 on the right side via bearings. The lead screw 21 is parallel to the slide rod 19. One end of the lead screw 21 is fixedly connected to the motor shaft of the drive motor 22 via a coupling. The drive motor 22 is bolted to a support leg 4. A nut 23 matching the lead screw 21 is bolted to the right end of the movable frame 17.

[0026] While the gantry frame 6 moves back and forth and drives the flame cutting head 14 to cut the plate, the drive motor 22 drives the lead screw 21 to rotate. The lead screw 21 acts on the lead screw nut 23 and drives the movable frame 17 and the cooling water tank 18 to move synchronously with the gantry frame 6, so that the cooling water tank 18 is kept directly below the gantry frame 6. The cooling water tank 18 collects the slag produced by the flame cutting head 14 cutting the plate.

[0027] like Figure 4 As shown, a filter tray 24 is provided inside the cooling water tank 18. Both the cooling water tank 18 and the filter tray 24 are elongated strips extending along the width direction of the frame 1. Multiple filter holes are evenly distributed on the bottom wall of the filter tray 24. Lifting plates 25 are respectively provided at both ends of the cooling water tank 18 along its length direction. The lifting plates 25 are driven to move vertically by telescopic components. The lower end of the lifting plate 25 is integrally formed with a support plate 26 for supporting the bottom of the filter tray 24. The support plate 26 extends horizontally. Specifically, after the plate is cut, the movable frame 17 and the cooling water tank 18 are moved by the lead screw 21, so that the cooling water tank 18 is moved to the bottom of one end of the frame 1 along the length direction, so that the filter tray 24 can be taken out later. Then, the lifting plate 25 and the support plate 26 are raised by the telescopic component. The support plate 26 raises the filter tray 24 and moves it outside the cooling water tank 18. The molten slag that has fallen into the cooling water tank 18 is retrieved by the filter tray 24. Then the filter tray 24 can be removed from the top of the two support plates 26 to pour out the molten slag.

[0028] The lifting plate 25 is attached to the side wall of the cooling water tank 18. A vertically extending guide rib 2 is welded on the side of the lifting plate 25 that is attached to the cooling water tank 18. The cross-section of the guide rib 2 is T-shaped. The inner wall of the cooling water tank 18 is provided with a guide groove 27 that matches the guide rib 2, thereby improving the stability of the lifting plate 25 moving up and down.

[0029] The telescopic component includes two cylinders 28 bolted to the left and right ends of the cooling water tank 18. The piston rods of the cylinders 28 extend upwards, and the upper end of the lifting plate 25 extends beyond the outside of the cooling water tank 18. A fixing seat 29 is bolted to the outer side of the upper end of the lifting plate 25, and the fixing seat 29 is bolted to the upper end of the piston rod of the corresponding cylinder 28. The extension of the cylinders 28 causes the lifting plate 25 and the support plate 26 to rise. The support plate 26 moves the filter tray 24 upwards and out of the outside of the cooling water tank 18. The filter tray 24 can be removed from the top of the two support plates 26 to pour out the slag. After the slag is poured out, the filter tray 24 is placed back on the top of the two support plates 26. Then, the retraction of the cylinders 28 causes the lifting plate 25 and the support plate 26 to descend, and the support plate 26 moves the filter tray 24 downwards into the cooling water tank 18.
