Description

Technical Field

[0001] This utility model relates to the field of angle steel cutting technology, and in particular to an angle steel fixed-length cutting device. 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. 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, cable trench supports, power piping, busbar support installation, and warehouse shelves, etc. After processing, angle steel needs to be cut into certain lengths.

[0003] Chinese utility model patent CN221087390U discloses a fixed-length cutting device for angle steel, including a cutting mechanism, a first conveying mechanism, and a second conveying mechanism. The cutting mechanism includes a fixed base, a hydraulic device, an upper cutter, and a lower cutter. A worktable is fixed to the lower part of the fixed base. The lower cutter is fixed to the worktable. The hydraulic device is mounted on the fixed base, with its piston rod vertically downward and directly above the worktable. The upper cutter is fixed to the end of the piston rod of the hydraulic device. The upper and lower cutters are triangular and adapted to the angle steel to be cut, with the bottom edges of their facing sides forming cutting edges. The first and second conveying mechanisms are respectively positioned at the rear and front ends of the fixed base along the conveying direction of the angle steel, conveying the angle steel to be cut. This utility model can re-cut angle steel with head and tail defects, achieving the effect of waste utilization.

[0004] Most existing angle steel cutting devices rely on manual measurement and marking to determine the cutting length. The manual operation process is cumbersome. When cutting angle steel of different lengths, the position of the angle steel needs to be manually adjusted. At the same time, the operator needs to manually push the stack of angle steel towards the cutting device. Therefore, the existing cutting devices have the problem of slow cutting efficiency.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Example 1

This embodiment provides a fixed-length cutting device for angle steel, including an angle steel body 1. A fixed-length cutting mechanism 2 is slidably connected to the outer surface of the angle steel body 1. A limiting mechanism 3 is connected to the inner wall of the outer surface of the fixed-length cutting mechanism 2. The fixed-length cutting mechanism 2 includes a lower cutting tool 204 slidably connected to the outer surface of the angle steel body 1. A cutting frame 201 is fixedly connected to the outer surface of the lower cutting tool 204. A fixing plate 208 and a roller rangefinder 206 are fixedly connected to the inner wall of the cutting frame 201. The detection wheel of the roller rangefinder 206 is in contact with the outer surface of the angle steel body 1. A drive roller 209 is rotatably connected to the outer surface of the fixing plate 208. A first hydraulic telescopic rod 210 is fixedly connected to the upper surface of the cutting frame 201. A reduction motor 207 is fixedly connected to the outer surface of the fixing plate 208. The output shaft of the reduction motor 207 is fixedly connected to the outer surface of the drive roller 209.

[0032] Specifically, a control panel 205 is fixedly connected to the outer surface of the cutting frame 201. The outer surface of the control panel 205 is electrically connected to the outer surfaces of the first hydraulic telescopic rod 210, the reduction motor 207, and the roller rangefinder 206 via wires. The outer surface of the drive roller 209 is in contact with the outer surface of the angle steel body 1, and the drive roller 209 is made of rubber. The first hydraulic telescopic rod 210 is fixedly connected to the upper surface of the cutting frame 201. The output end of the first hydraulic telescopic rod 210 is fixedly connected to the lifting plate 202. The outer surface of the lifting plate 202 is slidably connected to the inner side of the cutting frame 201, and the lower surface of the lifting plate 202 is fixedly connected to the cutting frame 201.

[0033] Furthermore, the roller rangefinder 206 detects the moving distance of the angle steel in real time, and combined with the preset length feedback of the control panel 205, precise cutting is achieved. The geared motor 207 drives the rubber drive roller 209 to ensure stable and slip-free conveying of the angle steel. The synergistic effect of the limit roller 304 and the rotating shaft 306 effectively prevents deviation and significantly improves the cutting quality and efficiency.

[0034] Example 2

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The limiting mechanism 3 includes a second hydraulic telescopic rod 302 that is fixedly connected to the inner wall of the cutting frame 201. The output end of the second hydraulic telescopic rod 302 is fixedly connected to a connecting frame 303. The outer surface of the connecting frame 303 is rotatably connected to a limiting roller 304.

[0036] The outer surface of the cutting frame 201 is fixedly connected to a fixing frame 305, and the outer surface of the fixing frame 305 is rotatably connected to a rotating shaft 306. The outer surface of the rotating shaft 306 is in contact with the outer surface of the angle steel body 1. The limiting mechanism 3 also includes a collection cart 301 set on one side of the cutting frame 201. The lower surface of the collection cart 301 is fixedly connected to multiple sets of universal wheels.

[0037] Furthermore, the entire cutting process is centrally controlled through the control panel 205. Operators only need to perform simple operations to complete the fixed-length cutting of angle steel, which is easy to operate. At the same time, the design of the collection trolley 301 facilitates the collection and transportation of the cut angle steel, reduces the amount of manual handling, improves work efficiency, and reduces labor intensity.

[0038] Working Principle: First, the operator must carefully check whether each component of the equipment is operating normally to ensure that the cutting equipment is in good working condition. After preparation, the angle steel body 1 is placed stably on the outer surface of the rotating shaft 306. The rotating shaft 306 not only supports the angle steel body 1 but also reduces the friction of the angle steel during movement, making the movement of the angle steel smoother. After placing the angle steel, the operator slowly pushes the angle steel body 1 upward toward the cutting tool 203 and the limiting roller 304 to prepare for subsequent limiting and cutting operations. Next, the second hydraulic telescopic rod 302 is activated. The output end of the second hydraulic telescopic rod 302 drives the connecting frame 303 to move precisely downward, causing the limiting roller 304, which is rotatably connected to the outer surface of the connecting frame 303, to gradually approach the angle steel body 1 until the outer surface of the limiting roller 304 is in close contact with the angle steel body 1. The function of the limiting roller 304 is to restrict the position of the angle steel during movement, prevent it from shifting, and ensure cutting accuracy. Meanwhile, the rotational connection design of the limiting roller 304 can reduce the frictional resistance between it and the angle steel body 1, and avoid damage to the surface of the angle steel.

[0039] After the limit operation is completed, the reduction motor 207 is started. The output shaft of the reduction motor 207 drives the drive roller 209 to rotate at a constant speed. Since the drive roller 209 is made of rubber, its outer surface has a large frictional force with the angle steel body 1. This frictional force can effectively drive the angle steel body 1 to move downward in the direction of cutting tool 204. During the movement of the angle steel, the detection wheel of the roller rangefinder 206 always maintains close contact with the outer surface of the angle steel body 1. As the angle steel moves, the detection wheel rolls synchronously. The sensor inside the roller rangefinder 206 is an OMRON sensor. The E6C2-CWZ6 can detect parameters such as the number of rotations and circumference of the rollers, accurately calculate the moving distance of the angle steel body 1, and transmit the data to the control panel 205 in real time. When the roller rangefinder 206 detects that the moving distance of the angle steel body 1 has reached the preset length, the system will send a signal, at which time the first hydraulic telescopic rod 210 will be activated. The output end of the first hydraulic telescopic rod 210 will quickly drive the lifting plate 202 to move downward. Since the lifting plate 202 is connected to the cutting frame 201, and the outer surface of the lifting plate 202 slides on the inner side of the cutting frame 201, the lifting plate 202 moves downward. The movement of the lowering plate 202 will cause the cutting frame 201 to move downwards synchronously. As the cutting frame 201 descends, the upper cutting tool 203 below the cutting frame 201 gradually approaches the lower cutting tool 204, ultimately achieving precise cutting of the angle steel body 1. After cutting, the cut angle steel body 1 falls into the collection cart 301. Multiple sets of universal wheels installed on the lower surface of the collection cart 301 make the collection cart 301 flexible and convenient to move. Operators can easily push the collection cart 301 to transport the cut angle steel to a designated location for storage or subsequent processing.
