Hand-held reinforcing steel bar hoop bending and straightening machine for building and use method thereof

Abstract

The invention discloses a hand-held reinforcing steel bar hoop bending and straightening machine for building. The machine comprises an upper shell and a lower shell, a straightening device and a hoop bending device are installed on the same machine, meanwhile, the machine is held by hand so that an operator can carry the machine conveniently, the working efficiency is improved, when the operator needs to switch working states, the rotating speed of a motor is reduced, a handle is separated from a positioning nail and the handle is slowly rotated, When a third helical bevel gear rotates, helical blocks are meshed with the third helical bevel gear to switch the required functions, when the size of reinforcing steel bars is changed, a rotating wheel and a fan-shaped fastening block move up and down and are tightly attached to the reinforcing steel bars by rotating an annular end cover and adjusting the positions of the fan-shaped fastening block and the rotating wheel, and the machine is suitable for straightening the reinforcing steel bars of different sizes; and when a long shaft rotates, a first small gear located at the right side is meshed with a first tooth block in a first long groove and moves up and down, and second guide blocks and guide grooves located at the left side and the right side improve the stability of a rotating wheel plate during straightening rotation and prevent the rotating wheel plate from turning over and displacing.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a hand-held steel bar bending hoop straightening machine for construction and a use method thereof. Background technique [0002] Reinforcement refers to steel for reinforced concrete and prestressed reinforced concrete, which is circular in cross-section and sometimes square with rounded corners. Including smooth round steel bars, ribbed steel bars, and twisted steel bars, they are widely used in various building structures. Especially for large, heavy, light thin-walled and high-rise building structures, in actual use, it is often necessary to straighten or bend the steel bars before they can be used in construction. After straightening, the steel bars need to be transported to the required work Location, during the transportation process, the straightened steel bars are collided or squeezed, resulting in their straightness not meeting the required standards. At this time, it ...

Problems solved by technology

Especially for large, heavy, light thin-walled and high-rise building structures, in actual use, it is often necessary to straighten or bend the steel bars before they can be used in construction. After straightening, the steel bars need to be transported to the required work Location, during the transportation process, the straightened steel bars are collided or squeezed, resulting in their straightness not meeting the required standards. At this time, it is necessary to transport the unqualified steel bars back to the processing site for re-straightening, and the cost Labor and efficiency, and in the process of use, it is often found that the number of hoops is not enough, so it needs to be transported back to the processing site, which consumes a lot of time and affects work efficiency
