Description

Technical Field

[0001] The utility model relates to the technical field of tubular steel material cutting, in particular to a cutting device for tubular steel materials. Background Art

[0002] Steel is a material of a certain shape, size and performance made of ingots, billets or steel through pressure processing. Most steel processing is done through pressure processing, which causes the processed steel (billets, ingots, etc.) to undergo plastic deformation. According to the different processing temperatures of steel, it can be divided into cold processing and hot processing; according to the different cross-sectional shapes, steel can be divided into four categories: profiles, plates, pipes and metal products. When using steel on industrial sites, it is necessary to cut the steel into standard specifications according to the required length. At present, a cutting machine is generally used. Two operators unfold the steel one by one, and then use the cutting machine to cut the steel of the required specifications.

[0003] When some existing cutting machines are in use, there will be a support frame to lift the steel, so as to facilitate the movement and cutting of the steel. However, when moving the steel, most of the workers move the steel manually, which is not only inconvenient, but also leads to the situation that the moving distance is not accurate enough. In addition, when the existing cutting machine cuts multiple steels at a time, it is necessary to use tape or plastic bags to wrap and fix the multiple steels before cutting, which is not convenient and will reduce the cutting efficiency of the steel.

[0004] At the same time, some existing cutting devices need to limit the steel when cutting, so that the steel will not be shifted as the cutting blade rotates. However, when cutting multiple steels, the shape of the steels after connection is not regular, which affects the limiting effect of the steels, reduces the limiting effect of the steels, and easily causes the steels to shift during the cutting process.

A pushing mechanism 3 is installed in the inner cavity of the support frame 2. The pushing mechanism 3 can push the steel, so as to facilitate the cutting of the steel and also facilitate the control of the moving distance of the steel, so as to facilitate the device to cut steel of different lengths. The surface of the support frame 2 is provided with The inner cavity of the mounting groove 4 is rotatably connected with a double-threaded rod 5, one end of the double-threaded rod 5 penetrates the outer side of the supporting frame 2 and is rotatably connected with the inner wall of the penetration place, and a handle is installed at one end of the double-threaded rod 5, under which it is convenient for the staff to rotate the double-threaded rod 5, and both sides of the surface of the double-threaded rod 5 are threadedly connected with sleeves 6, and the surface of the sleeve 6 is slidably connected with the inner wall of the mounting groove 4, under which the sleeve 6 can move without being affected by the surface thread of the double-threaded rod 5. The stability of the sleeve 6 during movement is effectively improved, and the top of the sleeve 6 is rotatably connected with a guide roller 7, and under the action of the guide rollers 7 on both sides, the steel can be limited when the pushing mechanism 3 pushes the steel, so that It will not move to the sides of the support frame 2 when moving, so that the position of the steel can be more accurate, further facilitating the device to cut the steel, and under the action of the guide roller 7, the friction between the steel and the guide roller 7 can be reduced, so that the pushing mechanism 3 can move the steel more easily. One side of the surface of the support frame 2 is fixedly connected with a mounting frame 8, and the mounting frame 8 is designed as a U-shaped structure. The top of the inner cavity of the mounting frame 8 is bolted with an electric telescopic rod 9, and the output shaft of the electric telescopic rod 9 is fixedly connected with a movable frame 10. The movable frame 10 is designed as a U-shaped structure. The inner wall of the movable frame 10 is fixedly connected to a limit plate 11, and the limit plate 11 is designed as a rubber material. Here, when needed, the movable frame 10 can drive the limit plate 11 to The steel that needs to be limited is squeezed, and it can be deformed under the action of the material of the limiting plate 11 to facilitate the limiting of multiple steels, which is more convenient and increases the applicability of the device.

[0024] It is worth noting that the technical features such as the cutting mechanism 1 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control method and spatial arrangement method of these technical features can be selected according to conventional practices in the field, and this technical solution will not be further elaborated.

[0025] Working principle: First, place the steel to be cut on the surface of the support frame 2, and multiple steels can be placed. Then, the staff rotates the bidirectional threaded rod 5 according to the number of steels to drive the guide roller 7 to move through the sleeve 6 to guide the steel. Then, turn on the stepper motor 31. Under the action of the stepper motor 31, the lead screw 32 drives the movable sleeve 33 to move, so that the push plate 34 pushes the steel to facilitate the movement of the steel. Then, after the steel moves to a suitable position, turn off the stepper motor 31 and turn on the electric telescopic rod 9. Under the action of the electric telescopic rod 9, the limit plate 11 can be driven by the movable frame 10 to squeeze the steel, so that the limit plate 11 is deformed to limit the steel. Then, turn on the cutting mechanism 1 to cut the steel.
