Description

Technical Field

[0001] This utility model belongs to the field of steel plate processing, specifically a steel plate flame cutting device. Background Technology

[0002] Flame cutting devices are widely used in the processing of steel materials such as steel plates and steel beams. They have the advantages of high cutting depth and wide applicability. However, due to the low cutting accuracy, after cutting the steel, the cut surface often needs to be further processed to meet the requirements of the steel. Patent CN218311361U, entitled "A Flame Cutting Device for Steel Plate Processing", discloses a device that can process steel plates. However, when cutting steel plates, it is sometimes necessary to cut a bevel on one side of the steel plate. However, the angle of the flame cutting device in the original device cannot be adjusted. Therefore, we designed a flame cutting device for steel plates with an adjustable angle. Utility Model Content

In this embodiment, four electric telescopic rods 2 are provided, located at the four corners of the workbench 1, which will not affect the placement of the steel plate. The top of the movable ends of several electric telescopic rods 2 are fixedly installed on the same fixed plate 13. A first lead screw 3 is rotatably installed on the fixed plate 132. The two ends of the first lead screw 3 are connected to the inner holes of bearing seats through bearings. The bearing seats are fixedly installed on the bottom side of the fixed plate 13. A drive motor 4 capable of driving the first lead screw 3 to rotate is fixedly installed on the fixed plate 13. The drive motor 4 is fixedly installed on the fixed plate 13. The output shaft of the drive motor 4 is coaxial with and fixedly connected to one end of the first lead screw 3. The outer circumferential thread of the first lead screw 3... The screw nut 5 is installed in conjunction with the first lead screw 3. The screw nut 5 can only move left and right along the first lead screw 3, and cannot rotate with the first lead screw 3. A movable plate 6 is fixedly installed on the bottom side of the screw nut 5. Several movable blocks 7 are provided at the bottom of the movable plate 6. A worm gear 8 is rotatably installed on one side of the movable block 7. The worm gear 8 is rotatably installed on the first fixed block 9 via a coaxial bearing. The first fixed block 9 is fixedly installed on the movable block 7. A worm 9, meshing with the worm gear 8, is rotatably installed on the movable block 7. The outer circumferences at both ends of the worm 9 are connected to the inner holes of a bearing seat. The bearing seat is fixedly installed on the movable block 7. The first fixed block 9 increases the distance between the worm gear 8, the worm 9, and the movable block 7, thereby facilitating the rotation of the worm 9. A flame cutter 10 is fixedly installed on the worm gear 8. This utility model has a simple structure and ingenious design. The angle of the flame cutter 10 can be adjusted according to actual needs, enabling both vertical cutting and bevel cutting of steel plates. It is easy to operate, meets practical needs, and is suitable for widespread application. When using this utility model, first place the steel plate to be cut on the workbench 1, control the electric telescopic rod 2 to shorten, the movable end of the electric telescopic rod 2 drives the fixed plate 13 and the flame cutter 10 to move downwards until the flame cutter 10 moves to a suitable height, control the electric telescopic rod 2 to stop moving downwards, rotate the worm 9 through the third handwheel 12, the worm 9 drives the worm wheel 8 to rotate, the worm wheel 8 drives the second fixed block 11 and the flame cutter 10 to rotate, adjust the angle of the flame cutter 10, when the flame cutter 10 rotates to a suitable angle, stop rotating the worm 9, start the flame cutter 10, at this time power on the drive motor 4, start the drive motor 4, the output shaft of the drive motor 4 drives the first lead screw 3 to rotate, the lead screw 5 drives the moving plate 6, the moving block 7 and the flame cutter 10 to move along the first lead screw 3, at this time the flame cutter 10 cuts the steel plate, the angle of the cut surface of the steel plate after cutting can reach the specified angle.

[0018] Specifically, as shown in the figure, the workbench 1 in this embodiment is a box with an open top side. Several first horizontal plates 20 are fixedly installed inside the box. The height of the first horizontal plates 20 is higher than the top side of the box, which can reduce the contact between the flame and the workbench 1 when cutting steel plates, thus reducing damage to the workbench 1. There are gaps between the first horizontal plates 20. A strip-shaped through slot 21 communicating with the inside of the box is opened on one side of the bottom of the box. The bottom of the box and the strip-shaped through slot 21 are slidably installed with the same drawer 22. The drawer 22 can close the strip-shaped through slot 21, and at the same time, the drawer 22 can be moved out of the box to facilitate the cleaning of impurities inside the drawer 22. A U-shaped rod 23 is fixedly installed on one side of the drawer 22. When it is necessary to cut the steel plate, the steel plate is placed on the first horizontal plate 20. At this time, the flame cutter 10 is started to cut the steel plate. The waste generated during the cutting process falls into the box through the gaps between the first horizontal plates 20. After the cutting is completed, the drawer 22 is pulled by the U-shaped rod 23 to clean the waste that has fallen into the drawer 22.

[0019] Specifically, as shown in the figure, several second horizontal plates 30 are fixedly installed on the top of the box body in this embodiment. The height of the second horizontal plates 30 is slightly higher than the height of the first horizontal plate 20. The first horizontal plates 20 and the second horizontal plates 30 are arranged in a grid pattern, with several first horizontal plates 20 and second horizontal plates 30 staggered to form several grid patterns. The height of both the first horizontal plates 20 and the second horizontal plates 30 is higher than the workbench 1, which allows the flame to contact the box body during cutting and reduces damage to the box body. The staggered arrangement of the first horizontal plates 20 and the second horizontal plates 30 can prevent the cut steel plates from being too small and falling into the box body through the gaps between the first horizontal plates 20 when cutting smaller steel plates.

[0020] Specifically, as shown in the figure, the movable plate 6 in this embodiment has a T-shaped groove 40, and T-shaped sliders 41 are fixedly installed on the movable block 7. The T-shaped sliders 41 are slidably installed in the T-shaped groove 40, and can only slide within the T-shaped groove 40, thus limiting the movement of the movable block 7 and making the movement of the movable block 7 more stable. When it is necessary to adjust the position of the flame cutter 10, the movable block 7 is slid, so that the T-shaped sliders 41 slide within the T-shaped groove 40. When the flame cutter 10 moves to the appropriate position, the sliding of the movable block 7 is stopped.

[0021] Specifically, as shown in the figure, the movable block 7 in this embodiment has a first through slot 50, and several first through slots 50 are provided with the same second lead screw 51. The second lead screw 51 is rotatably mounted on the movable plate 6. The outer circumferences of both ends of the second lead screw 51 are connected to the inner holes of the bearing seats through bearings. The bearing seats are fixedly mounted on the movable plate 6. The movable block 7 has a second through slot 52, and a crossbar 53 is slidably mounted in the second through slot 52. A first vertical plate 54 is fixedly mounted on one end of the crossbar 53. The first vertical plate 54 and the movable block 7 are elastically connected by a spring 55. The spring 55 is fitted on the outer circumference of the crossbar 53, and one end of the spring 55 is fixedly connected to one side of the first vertical plate 54. The other end of the spring 55 is fixedly connected to one side of the moving block 7, and the other end of the crossbar 53 is fixedly installed with the third fixing block 56. The third fixing block 56 is located in the first through groove 50 and can only move within the first through groove 50. A threaded groove 57 is opened on the third fixing block 56. The threaded groove 57 meshes with the second lead screw 51. The threaded groove 57 is a semi-circular threaded groove. The third fixing block 56 is located on one side of the second lead screw 51. Therefore, by pulling the crossbar 53, the third fixing block 56 can be moved so that the threaded groove 57 no longer meshes with the second lead screw 51. One end of the second lead screw 51 is fixedly installed with the coaxial first handwheel 58. When the flame cutter 10 needs to be moved, the first vertical plate 54 pulls the horizontal bar 53, and the third fixing block 56 on the horizontal bar 53 moves. The spring 55 is stretched, causing the threaded groove 57 to separate from the second lead screw 51, releasing the limitation on the moving block 7. At this time, the moving block 7 can be moved quickly, thereby causing the moving block 7 to drive the flame cutter 10 to move. When the flame cutter 10 moves to the appropriate position, the first vertical plate 54 is released. Under the action of the spring 55, the horizontal bar 53 and the third fixing block 56 are reset, and the threaded groove 57 re-engages with the second lead screw 51, limiting the moving block 7 and the flame cutter 10. When several flame cutters 10 need to be moved at the same time, the second lead screw 51 is rotated by the first handwheel 58, and several third fixing blocks 56 drive the moving block 7 and the flame cutter 10 to move synchronously.

[0022] Furthermore, as shown in the figure, in this embodiment, the first lead screw 3 is located on one side of the workbench 1, and a slide rod 60 is provided on the other side of the workbench 1. The two ends of the slide rod 60 are respectively fixedly installed on the fixed plate 13, and a sliding sleeve 61 is slidably installed on the outer periphery of the slide rod 60. The moving plate 6 is fixedly connected to the sliding sleeve 61. When the first lead screw 3 rotates, since the moving plate 6 is fixedly connected to the sliding sleeve 61 and the lead screw nut 5, the lead screw nut 5 cannot rotate with the first lead screw 3. The lead screw nut 5 drives the moving plate 6 to move along the first lead screw 3, and the moving plate 6 drives the sliding sleeve 61 to slide along the slide rod 60.

[0023] Furthermore, as shown in the figure, in this embodiment, a second vertical plate 70 is fixedly installed on both sides of the workbench 1. A threaded through hole 71 is opened on the second vertical plate 70, and a threaded rod 72 is installed in the threaded through hole 71. A clamping plate 73 is rotatably installed at one end of the threaded rod 72 that is close to each other. The bottom side of the clamping plate 73 slides in contact with the top side of the second horizontal plate 30. Insertion rods 75 are fixedly installed on both sides of the clamping plate 73. Insertion holes 76 are opened on the second vertical plate 70 corresponding to the insertion rods 75. The insertion rods 75 are slidably installed in the corresponding insertion holes 76. When the clamping plate 73 moves, the insertion rods 75 can slide in the corresponding insertion holes 76, limiting the clamping plate 73 and preventing it from rotating with the threaded rod 72. A coaxial second handwheel 74 is fixedly installed at the other end of the threaded rod 72. By rotating the threaded rod 72 with the handwheel 74, the threaded rod 72 drives the clamping plate 73 to move closer together, thereby clamping the steel plate to be cut and preventing it from moving during the cutting process.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
