Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction technology, and in particular to a cutting device for angle steel in construction. Background Technology
[0002] Angle steel, commonly known as angle iron, is a long strip of steel with two sides perpendicular to each other, forming an angle. National standard angle steel refers to steel with a minimum deviation within the national standard range of 0.25 mm. Angle steel is also divided into equal-sided and unequal-sided angle steel. Angle steel can be used to form various load-bearing components according to different structural needs, and can also be used as connecting parts between components. It is widely used in various building structures and engineering structures, such as roof beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, and warehouse shelves. Angle steel belongs to carbon structural steel for construction, and is a simple cross-section steel material, mainly used for metal components and factory frames. In use, it requires good weldability, plastic deformation performance, and a certain mechanical strength. The raw material for producing angle steel is low-carbon square steel billet, and the finished angle steel is delivered in hot-rolled, normalized, or hot-rolled condition. The main inspection items for evaluating the performance of angle steel are tensile tests and bending tests. Indicators include yield point, tensile strength, elongation, and bending qualification. Most existing angle steel production and cutting equipment requires manual control of the cutting length, making it impossible to achieve fixed-length cutting. Secondly, when cutting the same angle steel multiple times, the clamps need to be opened and the position of the angle steel repeatedly to keep it under the blade assembly, which reduces work efficiency. Furthermore, the angle steel cutting equipment on the market in the past often produced a lot of dust during cutting, which affected the health of the workers. Utility Model Content

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] like Figure 1-4As shown, a cutting device for angle steel in construction includes two sets of support frames 1. A workbench 2 is fixedly installed on the inner side of the two sets of support frames 1 near the upper side. A cutting mechanism 3 is installed on the upper side of the support frames 1 and the workbench 2. A dust extraction mechanism 4 is installed on one side of the workbench 2. The cutting mechanism 3 includes a cutting machine body 31 movably installed on one side of the workbench 2 near the rear end. A pad block 32 is fixedly installed on the upper end of the workbench 2 near one side. Two sets of slide rails 33 are fixedly installed on the upper end of each of the two sets of support frames 1. Slider blocks 34 are movably installed on the outer side of each of the four sets of slide rails 33. The upper ends of the two sets of sliders 34 near the front are fixedly connected to mounting plates 35. The front end of the mounting plate 35... A motor 36 is installed, and a gear 37 is fixedly connected to the rear side of the motor 36. A rack 38 is movably connected to the lower side of the gear 37. Two of the four sets of sliders 34 near the rear side are fixedly provided with U-shaped frames 39 at the upper end of the mounting plate 35. A hydraulic cylinder 310 is fixedly installed at the upper end of the U-shaped frame 39 near the center. A telescopic rod 311 is fixedly provided at the lower side of the hydraulic cylinder 310. A pressure block 312 is fixedly connected to the lower end of the telescopic rod 311. Connecting rods 313 are fixedly provided at the front and rear sides of the lower end of the U-shaped frame 39 near the pressure block 312. A support block 314 is fixedly connected between the two sets of connecting rods 313. A limit groove 315 is opened on the upper side of the worktable 2 corresponding to the position of the support block 314.
[0021] In this embodiment, a scale is fixedly installed at the front end of the front group of the two sets of support frames 1. The slider 34 is limited to slide on the outside of the slide rail 33. The mounting plate 35 is L-shaped. The rotating shaft of the motor 36 passes through the center of the front side of the mounting plate 35 and is connected to the gear 37. The gear 37 and the rack 38 are meshed. The rack 38 is fixedly connected to the front group of the two sets of support frames 1. The telescopic rod 311 passes through the center of the U-shaped frame 39. The support block 314 is limited to slide on the inside of the limiting groove 315.
[0022] Specifically, the cutting machine body 31 uses the existing equipment structure. The two sides of the angle steel are placed on the upper side of the pad block 32 and the support block 314, respectively. The hydraulic cylinder 310 is activated to control the telescopic rod 311 to drive the pressure block 312 to press down and fix one side of the angle steel. The cutting machine body 31 is then activated to cut the angle steel. When the next cutting operation is needed, the motor 36 is activated to drive the gear 37 to rotate. This, in turn, engages with the rack 38 to drive the slider 34, mounting plate 35, and U-shaped frame 39 to slide on the upper side of the slide rail 33, thereby moving the angle steel towards the cutting machine body 31. By observing the scale set at the front end of the front support frame 1, when the angle steel moves to the required cutting position, the cutting machine body 31 is activated to continue cutting the angle steel. This achieves multiple cuts with one fixation of the angle steel, avoiding the need to repeatedly open and adjust the position of the angle steel, improving work efficiency and saving time and effort.
[0023] In this embodiment, the dust collection mechanism 4 includes a cutting opening 41 on one side of the workbench 2. Several sets of dust collection holes 42 are provided on both sides of the inner side of the workbench 2 near the cutting opening 41.

The cutting opening 41 is located on the lower side of the cutting machine body 31, and the several sets of dust collection holes 42 are evenly arranged.
[0024] Specifically, the vacuum cleaner 45 is an existing equipment structure. By starting the vacuum cleaner 45, the cutting port 41 and several sets of suction holes 42 are used to absorb the dust generated during cutting. The dust enters the inside of the vacuum cleaner 45 through the suction hopper 43 and the connecting pipe 44, thereby collecting the dust during cutting and reducing the impact on the health of the workers.
[0025] Working principle:
[0026] In use, the cutting machine body 31 uses the existing equipment structure. The two sides of the angle steel are placed on the upper sides of the pad block 32 and the support block 314, respectively. The hydraulic cylinder 310 controls the telescopic rod 311 to press down the pressure block 312, fixing one side of the angle steel. The cutting machine body 31 then cuts the angle steel. When the next cutting operation is needed, the starting motor 36 drives the gear 37 to rotate, which in turn engages with the rack 38 to slide the slider 34, mounting plate 35, and U-shaped frame 39 on the upper side of the slide rail 33, thus moving the angle steel towards one side of the cutting machine body 31. This is observed... The scale set at the front end of the front support frame 1 moves to the required cutting position, and the cutting machine body 31 is started to continue cutting the angle steel. This achieves multiple cuts with one fixation of the angle steel, avoiding the need to repeatedly open the clamp to adjust the position of the angle steel, improving work efficiency and saving time and effort. In addition, the vacuum cleaner 45 is an existing equipment structure. By starting the vacuum cleaner 45, the cutting port 41 and several sets of suction holes 42 are used to absorb the dust generated during cutting. The dust enters the inside of the vacuum cleaner 45 through the dust collection hopper 43 and the connecting pipe 44, realizing the collection of dust during cutting and reducing the impact on the health of the workers.
