Technical Field

[0001] This utility model relates to the field of steel cutting technology, specifically a steel structure cutting device. Background Technology

[0002] Steel components refer to structural members made of angle steel, channel steel, H-beams, or combinations thereof. They have comprehensive advantages such as light weight, factory manufacturing, quick installation, short construction period, good seismic performance, fast investment recovery, and low environmental pollution. Their load-bearing capacity affects the quality of steel structure engineering construction and is an indispensable part of steel structure engineering construction. To meet the usage requirements of steel components, they are usually cut into the required dimensions using cutting devices. For example, a steel component clamping and cutting device disclosed in Chinese Patent Publication No. CN220259718U includes a worktable and a cutting device installed on the worktable. The worktable is equipped with a clamping device, which includes a transverse clamping mechanism and a longitudinal clamping mechanism. The transverse clamping mechanism includes at least three clamping plates, connecting rods, and a driving assembly that drives the clamping plates to move closer to each other. The top wall of the clamping plates is higher than the table surface of the worktable. At least three clamping plates are vertically arranged and parallel to each other. The connecting rods pass through all the clamping plates and are slidably connected to the clamping plates. The longitudinal clamping mechanism is located directly above the clamping plates. The clamping plate, connecting rod, and drive assembly of this application work together to clamp and fix the steel component in the horizontal direction, and the longitudinal clamping mechanism can clamp and fix the steel component in the vertical direction, thereby improving the cutting accuracy.

[0003] However, in practical applications, the above-mentioned device still has the following shortcomings: In the process of using steel components, it is often necessary to cut the whole steel into multiple steel segments of equal length. Although the above-mentioned device can adjust the cutting length by adjusting the alignment plate, it can only cut out one steel segment at a time, and the cutting efficiency is not ideal. Therefore, a steel structure cutting device was designed. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a steel structure cutting device that can cut a whole steel bar into multiple steel segments of equal length in one go, resulting in higher cutting efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A steel structure cutting device includes a cutting table, an abutment plate fixed on the cutting table, a plurality of cutting heads equidistantly arranged above the cutting table, a length adjustment mechanism for adjusting the spacing between adjacent cutting heads, a lifting mechanism for driving the length adjustment mechanism to rise or fall, and a displacement mechanism for driving the lifting mechanism to move back and forth. The displacement mechanism is mounted on a frame, and the frame is fixed on the cutting table.

[0007] Furthermore, the length adjustment mechanism includes a back plate, two mounting plates facing the front of the back plate, a length adjustment screw and a sliding rod connecting the two mounting plates, and multiple linkage sliders slidably connected to the length adjustment screw. The left end of the length adjustment screw passes through the mounting plate and is connected to an adjustment motor. The leftmost linkage slider has an internal threaded hole facing the length adjustment screw, and the rightmost linkage slider is fixed to an adjacent mounting plate. A drive shaft is provided on the back of the linkage slider, and connecting rod one and connecting rod two are hinged at their ends. Multiple connecting rods one are parallel to each other, and multiple connecting rods two are parallel to each other. Two adjacent drive shafts are respectively rotatably connected to the middle of connecting rod one and the middle of connecting rod two. The cutting head is fixed to the front of the linkage slider.

[0008] Furthermore, the lifting mechanism includes a lifting base, a lifting linear motor vertically arranged on the front of the lifting base, a lifting slide connected to the movable end of the lifting linear motor, and a length adjustment mechanism installed on the front of the lifting slide.

[0009] Furthermore, the displacement mechanism includes a longitudinal linear motor mounted longitudinally on the frame, a longitudinal slide rail mounted parallel to the longitudinal linear motor, a longitudinal slide block slidably connected to the longitudinal slide rail, the longitudinal slide block being fixedly connected to the movable end of the longitudinal linear motor, a transverse linear motor mounted on the longitudinal slide block, the output end of the transverse linear motor being driven and connected to the transverse slide block, and the lifting mechanism being mounted on the transverse slide block.

[0010] Furthermore, the cutting table is provided with a clamping groove, a clamping plate is slidably connected to the bottom of the clamping groove, a clamping screw is rotatably connected to the clamping groove, and a clamping motor is fixed at one end of the clamping groove. The clamping plate is positioned directly opposite the abutment plate.

[0011] The beneficial effects of this utility model are:

[0012] In practical applications, the front end of the steel to be cut is placed against the abutment plate. The distance between adjacent cutting heads is adjusted by the length adjustment mechanism. The length adjustment mechanism is driven to move downward by the lifting mechanism. During the cutting process, the displacement mechanism drives the lifting mechanism to move forward, cutting the steel into steel segments. By cutting simultaneously with multiple equally spaced cutting heads, the steel can be cut into multiple segments at one time, resulting in higher cutting efficiency. This invention can cut a whole steel bar into multiple steel segments of equal length at one time, resulting in higher cutting efficiency. Attached Figure Description

The displacement mechanism 6 is mounted on a frame 7, and the frame 7 is fixed on the cutting table 1.

[0019] In use, the front end of the steel to be cut is placed against the abutment plate 2. The distance between adjacent cutting heads 3 is adjusted by the length adjustment mechanism 4. The length adjustment mechanism 4 is driven to move down by the lifting mechanism 5. During the cutting process, the displacement mechanism 6 drives the lifting mechanism 5 to move forward, cutting the steel into steel segments. By cutting simultaneously with multiple equally spaced cutting heads 3, the steel can be cut into multiple segments at one time, resulting in higher cutting efficiency. This utility model can cut a whole steel bar into multiple steel segments of equal length at one time, resulting in higher cutting efficiency.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the length adjustment mechanism 4 includes a back plate 41, two mounting plates 42 facing the front of the back plate 41, a length adjustment screw 43 and a slide rod 44 connecting the two mounting plates 42, and multiple linkage sliders 45 slidably connected to the length adjustment screw 43. The left end of the length adjustment screw 43 passes through the mounting plate 42 and is connected to an adjustment motor 46. The leftmost linkage slider 45 has an internal threaded hole facing the length adjustment screw 43, and the rightmost linkage slider 45 is fixed to the adjacent mounting plate 42.

Multiple connecting rods 1 48 are parallel to each other, and multiple connecting rods 2 49 are parallel to each other. Two adjacent drive shafts 47 are rotatably connected to each other. The cutting head 3 is fixed to the front of the linkage slider 45 at the middle of rod 48 and the middle of connecting rod 49. In this embodiment, during the rotation of the length adjusting screw 43 driven by the adjusting motor 46, the length adjusting screw 43 drives the leftmost linkage slider 45 to slide along the slide rod 44 through the internal thread hole. Since the rightmost linkage slider 45 is fixed on the adjacent mounting plate 42, the leftmost linkage slider 45 drives the connecting rod 48 and connecting rod 49, which are hinged at the ends, to unfold. The transmission shaft 47 is rotated through the middle of connecting rod 48 and connecting rod 49 respectively, so that the adjacent linkage sliders 45 move closer or further away from each other, thereby adjusting the distance between adjacent cutting heads 3. The cutting head 3 is a laser cutting head 3, and there is also a laser generator connected to the laser cutting head 3 through an optical fiber.

In this embodiment, the lifting slide 53 is driven to rise or fall by the lifting linear motor 52, and the height of the cutting head 3 on the length adjustment mechanism 4 is adjusted so that it is close to the steel for cutting.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the displacement mechanism 6 includes a longitudinal linear motor 61 mounted longitudinally on the frame 7, a longitudinal slide rail 62 mounted parallel to the longitudinal linear motor 61, a longitudinal slide block 63 slidably connected to the longitudinal slide rail 62, the movable end of the longitudinal linear motor 61 fixedly connected to the longitudinal slide block 63, a transverse linear motor 64 mounted on the longitudinal slide block 63, and a transverse slide block 65 driven by the output end of the transverse linear motor 64. The lifting mechanism 5 is mounted on the transverse slide block 65. In this embodiment, during the cutting process of the cutting head 3, the longitudinal linear motor 61 drives the longitudinal slide block 63 to slide back and forth, cutting the steel on the cutting table 1 into steel segments, and the transverse linear motor 64 drives the transverse slide block 65 to slide laterally, improving the applicability of the equipment.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the cutting table 1 is provided with a clamping groove 11, and a clamping plate 12 is slidably connected to the bottom of the clamping groove 11. A clamping screw 13 is rotatably connected to the clamping groove 11, and a clamping motor is fixed at one end of the clamping groove 11. The clamping plate 12 is positioned directly opposite the abutment plate 2. In this embodiment, the clamping motor drives the clamping plate 12 to move through the clamping screw 13, so that the clamping plate 12 moves closer to the abutment plate 2, thereby clamping the steel between the abutment plate 2 and the clamping plate 12.

[0024] It also includes a control box, a display mounted on the front of the control box, and a PLC controller located inside the control box.
