Rapid fixing and cutting device for steel bars

Abstract

The invention relates to the field of buildings, and particularly relates to a rapid fixing and cutting device for steel bars. The rapid fixing and cutting device comprises a motor, wherein an outputshaft is mounted on one side of the motor; a driving straight gear is mounted at the other end of the output shaft and engaged with a driven straight gear; a transmission shaft is fixed to the middleof the driven straight gear; first driving bevel gears are mounted on the left portion and the right portion of the transmission shaft correspondingly; clamping devices are mounted at the upper ends of the first driving bevel gears; a second driving bevel gear is mounted in the middle of the transmission shaft; a cutting lifting device is mounted at the upper end of the second driving bevel gear;a cutting rotating device is mounted on one side of the cutting lifting device; and the transmission shaft is connected with symmetrically-arranged supporting plates through bearings. Through the arrangement of the driving straight gear, the driven straight gear, the transmission shaft, the first driving bevel gears, the second driving bevel gear, the clamping devices, the cutting lifting device and the cutting rotating device, when the steel bars are cut, strenuous fixing and dismounting during steel bar cutting are avoided, the cutting efficiency is improved, and labor force is reduced.

[0002] With the development of the modern mechanical processing industry, the requirements for cutting quality and precision are constantly improving, and the requirements for improving production efficiency, reducing production costs, and highly intelligent automatic cutting functions are also increasing. Reinforced bars refer to reinforced concrete and Steel for prestressed concrete, its cross-section is circular, sometimes square with rounded corners, including smooth round steel bar, ribbed steel bar, twisted steel bar, steel bar for reinforced concrete refers to the straight bar or bar for reinforced concrete reinforcement Coil-shaped steel, its shape is divided into two types: smooth round steel bars and deformed steel bars, and the delivery status is straight and coiled. It is a steel bar with ribs on the surface, usually with 2 longitudinal ribs and transverse ribs evenly distributed along the length direction. The shapes of the transverse ribs are spiral, herringbone, and crescent. The nominal diameter of the steel bar is equivalent to the nominal diameter of the light round steel bar with the same cross section. The nominal diameter of the steel bar is 8-50 mm. The recommended diameters are 8, 12, 16, 20, 25, 32, and 40 mm. Steel type: 20MnSi , 20MnV, 25MnSi, BS20MnSi, steel bars mainly bear tensile stress in concrete, and deformed steel bars have greater bonding capacity with concrete due to the action of ribs, so they can better withstand external forces. Steel bars are widely used in various buildings Structures, especially large, heavy, light thin-walled and high-rise building structures, steel bars often need to be cut during use, but the traditional steel bar cutting device has a complex structure and the efficiency of the feeding device is not high. The present invention proposes a steel bar cutting device for the above problems device

[0003] After retrieval, the Chinese patent No. CN111390069A discloses a steel bar cutting device, which relates to the technical field of cutting machines. The present invention includes a bracket, a lower platform and an upper platform, one end of the bracket is fixedly connected to the lower surface of the lower platform, and the lower platform The surface is fixedly connected with a vertical plate, the first surface of the vertical plate is provided with a switch, the first surface of the vertical plate is fixedly connected with the upper surface of the upper platform, the upper surface of the upper platform is equipped with a cylinder, the cylinder is electrically connected with the switch, and the lower end of the cylinder is fixedly connected with a connecting frame. In the present invention, by using the second motor, conveying device, spring and balls, the whole device can realize automatic feeding during the feeding process, which improves the feeding efficiency; by using the air cylinder and the first motor, the changing device can be realized by controlling the air cylinder The tool is lifted and lowered, and the tool is rotated by controlling the motor. The structure is simple and the cutting efficiency is high. However, the device does not optimize the steel bar fixing device. The traditional steel bar fixing device needs to be fixed manually. At the same time, after the cutting is completed, the fixing device needs to be removed manually. It is troublesome to use and wastes a lot of time, resulting in low cutting efficiency
