Description

Technical Field

[0001] This utility model belongs to the field of steel bar bending technology, and in particular relates to a steel bar bending device for house repair. Background Technology

[0002] A steel bar bending device for building repair is a portable mechanical device specifically designed for the maintenance and repair of reinforced concrete structures in existing buildings. Its core definition is: it can reshape straight or bent steel bars into specific angles (such as right angles, arcs, etc.) according to repair needs, to meet the technical requirements of building repair projects such as reinforcing joints, replacing damaged components, or adjusting reinforcement layout.

[0003] Traditional rebar bending devices require workers to bend a large number of rebars during use. However, most rebars are bent based on the workers' experience, resulting in inconsistent rebar lengths and significant errors. The bending length of the rebars cannot be well adjusted. Summary of the Invention

[0004] The purpose of this utility model is to provide a rebar bending device for house repair. Specifically, by setting an adjustment mechanism, pushing a push rod moves a limiting rod, causing a spring to compress and disengage the limiting rod from between the toothed plates. Then, pushing the upper sliding plate moves an adjustment plate. After placing the adjustment plate in the appropriate position, releasing the push rod releases the spring force, allowing the limiting rod to re-engage between the toothed plates, achieving the limiting effect. This method is simple to operate and allows for easy adjustment of the rebar length. It solves the problem of existing traditional rebar bending devices requiring workers to bend large quantities of rebar, often relying on worker experience for bending, resulting in inconsistent rebar lengths and significant errors, and failing to effectively adjust the bending length.

[0037] One specific application of this embodiment is:

[0038] When using the equipment, the operator first needs to install the round rod 18 to the threaded hole 152 on the surface of the turntable 15 via a threaded connection. Then, the auxiliary plate 161 and the limiting block are fixedly connected to the placement plate 16. The end of the limiting block 162 is then brought into contact with the right side of the auxiliary plate 161. The limiting block 162 is used to restrict the auxiliary plate 161, reducing the shaking of the reinforcing bar during rotation. The operator then stands on one side of the placement plate 16 and places the reinforcing bar from the placement plate 16 onto the turntable 15, so that the surface of the reinforcing bar contacts the surface of the fixing rod 151. The adjusting mechanism 2 is then used to adjust the reinforcing bar to a suitable length. Next, the bending process begins by pushing the push rod 25, which in turn pushes the U-shaped plate 251 forward. The U-shaped plate 251 then causes the connecting rod 252 to slide within the groove 261. Since the groove 261 is angled, when the connecting rod 252 is pushed forward, the sliding block 26 will shift to the left. Simultaneously, a slot is provided on the right side of the adjusting box 24, causing the sliding block 26 to drive the fixing rod 27 to slide within the slot of the adjusting box 24. Then, the fixing rod 27 will move the limiting rod 29, causing the spring 28 to compress and disengage the limiting rod 29 from between the toothed plates 211. Finally, the upper sliding plate 222 is pushed... 22 will drive the adjusting plate 23 to move. After the adjusting plate 23 is placed in the appropriate position, the push rod 25 is released. After the push rod 25 is released, the spring 28 will release its elasticity, causing the limiting rod 29 to re-insert between the toothed plates 211, achieving the limiting effect. After the length of the steel bar is adjusted appropriately, the fixing mechanism 3 is installed. First, a suitable fixing sleeve 31 is selected and fitted onto the round rod 18. It is checked that the surface of the fixing sleeve 31 can contact the surface of the steel bar. After the selected fixing sleeve 31 is suitable, it is fixed to the round rod 18. First, one side of the U-shaped rod 32 is inserted into the through hole 311, and then... Insert the other end of the U-shaped rod 32 into the positioning seat 33 to position it, then connect the bolt 34 to the internal thread of the through hole 322, and then continue to connect it to the threaded hole 181 after passing through the through hole 322, so that the fixing sleeve 31 is fixed to the round rod 18. Then start the motor 12, which will drive the small gear 121 to rotate, which will drive the large gear 141 to rotate, which will drive the rotating shaft 14 to rotate, which will drive the turntable 15 to rotate, which will drive the round rod 18 to rotate, which will drive the fixing sleeve 31 on the surface to rotate. The rotation of the fixing sleeve 31 will squeeze and bend the steel bar.
