Description

Technical Field

[0001] The utility model belongs to the technical field of bending machines, in particular to a steel bar bending machine for construction. Background Art

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, and sometimes square with rounded corners. During the reinforcement construction process, the reinforcement needs to be bent through a bending structure. During the construction process, rebar is needed as a supporting skeleton. During the skeleton process, some rebars are too long and need to be completely bent during the skeleton fixing process.

[0003] Rebar bending refers to bending or folding the steel bars according to the design requirements to form the desired curved shape. Rebar bending plays an important role in the construction of building structures and concrete components. Common bending shapes include right angles, arcs, etc.

[0004] In the current existing technology, during the construction process, a portable bending mechanism is generally used for bending. During bending, the bending point of the steel bar cannot be effectively guaranteed. Secondly, during the bending process, the verticality of the bottom of the bending point cannot be guaranteed, resulting in poor bending effect and affecting the shape of the steel bar skeleton. Therefore, a construction steel bar bending machine is proposed to address the above problems. Utility Model Content

[0008] Preferably, the limiting hook is an open structure, and an opening is formed between the end face of the limiting hook and the side face of the limiting buckle. When limiting the position of the steel bar, the steel bar enters the locking position through the opening.

[0009] Preferably, an arc-shaped gasket is provided on the side of the limiting buckle, and the concave surface of the arc-shaped gasket is arranged opposite to the curved surface of the limiting hook, which can better cooperate to achieve the tightening and fixation of the steel bar.

[0010] Preferably, a protective cover is provided on the side of one group of shrinkage structures, and a heating wire is provided on the inner side of the protective cover.

A protective cover 6 is arranged on the side face of one group of contraction structures 5, and a heating wire 7 is arranged on the inner side of the protective cover 6. The bending curvature of the heating wire 7 is the same as that of the limit hook 55. In the process of building construction, steel bars 4 are needed to support the skeleton. In the process of the skeleton, some steel bars 4 are too long, and the steel bars 4 need to be completely bent during the process of fixing the skeleton. In the process of bending, two limit hooks are used to fix the steel bars 4. 55 tightens the steel bar, and by rotating and pulling the screw rod 53, the limit hook 55 can be driven to pull toward the limit buckle 51, and the limit hook 55 and the limit buckle 51 can cooperate to fix the steel bar 4. The top shrinkage structure 5 mainly functions with the bending position, and the bottom shrinkage structure 5 only needs to work. In order to better ensure the state of the bottom steel bar 4, it can better ensure the bending support state. After clamping, the heating wire 7 is energized to heat the bending position, which can better shape and avoid the steel bar 4 from breaking during the bending process. At the same time, it reduces the force applied to the bending of the steel bar 4, which can be better bent during the construction process and achieve a better bending effect.

[0027] The top side of the fixed plate 2 is provided with a pressing structure 3, and the pressing structure 3 includes a mounting seat 31, and the mounting seat 31 is fixed on the top side of the fixed plate 2.

[0028] Working principle: During the construction process, steel bars 4 are needed to make a supporting skeleton. During the skeleton process, some steel bars 4 are too long, and the steel bars 4 need to be completely bent during the skeleton fixing process. During the bending process, the steel bars are fastened by two limit hooks 55. By rotating and pulling the screw rod 53, the limit hook 55 can be driven to pull toward the limit buckle 51. With the cooperation of the limit hook 55 and the limit buckle 51, the steel bars 4 can be fixed. The top shrinkage structure 5 mainly acts on the bending position, and the bottom shrinkage structure 5 only needs to work. In order to better ensure the state of the bottom steel bars 4, the bending support state can be better ensured. After clamping, the electric heating wire 7 is energized to heat the bending position, which can better shape the steel bars 4 to avoid breaking during the bending process. At the same time, the force applied to the bending of the steel bars 4 can be reduced, so that the steel bars 4 can be better bent during the construction process to achieve a better bending effect.
