Description

Steel bar straightening protection device

Technical Field

The utility model relates to the technical field of steel bar building materials, in particular to a steel bar straightening and protection device.

Background Art

During the forging and storage process, some of the steel bars may be bent, which may not meet the use requirements. In order to meet the use requirements, the steel bars need to be adjusted by a steel bar straightening machine to make the bent parts straight. During the process of adjusting the steel bars by the straightening machine, the straightening machine needs to fix the part to be straightened on the straightening machine. Due to the long length of the steel bars, some of the steel bars cannot be completely fixed by the straightening machine, and the unfixed parts are exposed outside the straightening machine. During the process of adjusting the steel bars by the straightening machine, the unfixed parts will swing and cause injuries. Therefore, we need a steel bar straightening protection device.

Most of the steel bar straightening protective devices on the market are not equipped with shock-absorbing structures. The steel bars directly hit the protective frame when swinging, making it very easy to deform and damage during long-term use. The vibration generated by the impact will cause the protective device to shake, making it prone to rollover and displacement, which can easily cause safety accidents. This problem is particularly prominent in protective devices with movable wheels or those that are easy to move and transport.

Based on this, it is necessary to study a steel bar straightening protection device.

The beneficial effects of the above technical solution are:

(1) The utility model provides a protective outer frame for support, and a protective inner frame for receiving the impact of the steel bars. The protective inner frame is spaced apart and mounted in the protective outer frame by a spring assembly. The small opening of the protective inner cavity is adjacent to the feed port of the steel bar straightening machine. The steel bars pass through the large opening of the protective inner frame and then pass through the small opening to enter the steel bar straightening machine. When the unfixed part of the steel bar collides, it will hit the protective inner frame. The spring assembly enables the protective inner frame to undergo relative displacement when impacted, thereby absorbing and dispersing the impact force, reducing the diffusion of the impact force to the entire device, reducing the possibility of the entire device tipping over or shifting, and improving the stability and safety of the device support. In addition, the protective inner frame acts as a buffer layer, which can reduce the destructive force of the direct impact of the steel bars, reduce the deformation and damage of the protective inner frame caused by the impact, and slow down the transmission of the impact force to the entire device, avoiding deformation and loosening of various connection nodes and other positions, thereby extending the service life of the device, reducing the frequency of maintenance and replacement, and reducing maintenance costs.

(2) The utility model fixes the protective outer frame on the support, and the bottom of the support is connected to a counterweight box by a screw lifting mechanism. When in use, the counterweight box can be lowered to the ground, which can not only provide additional support, but also lower the center of gravity of the device by adding counterweights in the counterweight box, thereby improving the stability of the device and further avoiding the problems of rollover and displacement.
