Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically to a steel bar bending device used in building construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of structures, or the process of turning the lines on design drawings into physical objects at designated locations. It includes foundation construction, main structure construction, roofing construction, and decoration construction. The site of construction work is called the "construction site" or "building site." Reinforcing steel is an important building material in construction projects. Depending on specific construction requirements, reinforcing steel needs to be bent. Currently, in existing technologies, such as the patent application number CN202220169260.1, a multi-angle bending device for reinforcing steel in construction is disclosed. Although it achieves multi-angle bending of reinforcing steel, this device requires manual operation of two drive rods to bend the steel, which greatly increases the labor intensity for workers. Furthermore, although the device can bend the steel into a U-shape, the width of the U-shaped steel needs to be adjusted according to construction requirements, and this device clearly lacks the function of adjusting the bending width, thus reducing the practicality of the bending device.

[0013] (III) Beneficial Effects

[0014] This utility model provides a steel bar bending device for building construction. It has the following beneficial effects:

[0015] 1. This rebar bending device for building construction, through its fine-tuning mechanism, first controls the stepper motor to reverse, which in turn drives the fine-tuning shaft to reverse. The fine-tuning shaft in turn drives two fine-tuning blocks and two fine-tuning carriers to move simultaneously in opposite directions. By controlling the distance between the two fine-tuning carriers, the bending width of the rebar can be quickly adjusted, enabling the bending device to process rebars with different bending widths. Then, controlling the two cranks to rotate forward drives the two adjusting rods to rotate forward, which in turn drives the two clamping plates to move downward simultaneously. When the bottom surfaces of the two clamping plates are in full contact with the top of the steel piece, the clamping and positioning of the rebar is quickly completed, thereby improving the stability of the rebar during bending and thus increasing the bending quality of the rebar.

[0016] 2. This steel bar bending device for building construction, through its bending mechanism, firstly ensures that the steel bar is centered, thus ensuring that the bending lengths at both ends are the same, thereby effectively improving the bending quality of the steel bar. Then, by controlling the activation of two cylinders, the two carriers can rotate in opposite directions at their far ends. The rotation of the two carriers can simultaneously rotate the bending shafts on the left and right sides. By rotating the bending shafts on both sides, multi-angle bending of the steel bar can be completed quickly. This bending method greatly improves the bending efficiency of U-shaped steel bars and also greatly reduces the labor intensity of workers. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] This utility model embodiment provides a steel bar bending device for building construction, such as... Figure 1-5 As shown, it includes a table 1, a fine-tuning mechanism 2, a bending mechanism 3, and support legs 4. The bottom of the fine-tuning mechanism 2 is fixedly connected to the top surface of the rear end of the table 1, the rear end of the bending mechanism 3 is fixedly connected to the front of the fine-tuning mechanism 2, and the top of the support legs 4 is fixedly connected to the four corners of the bottom surface of the table 1.

[0025] The fine-tuning mechanism 2 includes a station plate 201, a guide rail 202, fine-tuning blocks 203, fine-tuning holes 204, a fine-tuning shaft 205, a stepper motor 206, a fine-tuning carrier 207, a limiting groove 208, a clamping plate 209, an adjustment hole 210, an adjustment rod 211, and a crank handle 212. The bottom ends of the two station plates 201 are fixedly connected to the top surfaces of both ends of the table 1. The bottom of the guide rail 202 is fixedly connected to the middle of the top surface of the rear end of the table 1. The bottom ends of the two fine-tuning blocks 203 are engaged with the top surfaces of both ends of the guide rail 202. Two fine-tuning holes 204 are opened on both sides of the top of the two fine-tuning blocks 203. The middle section of the fine-tuning shaft 205 passes through the inner cavity of the two fine-tuning holes 204 and is embedded in the two sides of the two station plates 201 through bearings. The stepper motor 206... The bottom of the two fine adjustment carriers 207 is fixedly connected to the left rear of the top surface of the table 1, and the output shaft end of the right end of the stepper motor 206 is fixedly connected to the left end of the fine adjustment shaft 205. The rear ends of the two fine adjustment carriers 207 are fixedly connected to the front of the two fine adjustment blocks 203. The two limiting grooves 208 are opened on the rear surface of the inner cavity of the two fine adjustment carriers 207. The rear ends of the two clamping plates 209 are inserted into the inner cavity of the two limiting grooves 208. The two adjustment holes 210 are opened on the top surface of the two fine adjustment carriers 207. The bottom ends of the two adjustment rods 211 are inserted into the inner cavity of the two adjustment holes 210. The bottom ends of the two adjustment rods 211 are embedded in the middle of the top surface of the two clamping plates 209 through bearings. The bottom surface of the two cranks 212 is fixedly connected to the top end of the two adjustment rods 211.

[0026] In use, first place the rebar into the two fine-tuning carriers. The scale effectively ensures the rebar is centered, resulting in identical bending lengths at both ends. Then, control the stepper motor to reverse, which in turn drives the fine-tuning shaft to reverse. This reverse rotation moves the two fine-tuning blocks and the two fine-tuning carriers simultaneously in opposite directions. By controlling the distance between the two fine-tuning carriers, the bending width of the rebar can be quickly adjusted, enabling the bending device to process rebars with different bending widths. Next, control the two cranks to rotate clockwise, which in turn rotates the two adjusting rods clockwise. This rotation moves the two clamping plates downwards simultaneously, ensuring the bottom surfaces of the two clamping plates are fully... When the steel bar contacts the top, it is quickly clamped and positioned. During bending, the two cylinders are started first. The start of the two cylinders causes the two carriers to rotate in opposite directions. The rotation of the two carriers causes the bending shafts on the left and right sides to rotate simultaneously. By rotating the bending shafts on both sides, the steel bar can be bent at multiple angles quickly. This bending method greatly improves the bending efficiency of U-shaped steel bars. Finally, the crank is reversed. The reverse crank causes the two clamping plates to move upward and detach from the steel bar. At this time, the two ends of the U-shaped steel bar are moved upward. The clamping ends of the U-shaped steel bar can then be removed from the two fine-tuning carriers, so that the entire bending device can be used continuously.

[0027] Furthermore, the bending mechanism 3 includes a carrier plate 301, a frame 302, a bending shaft 303, a cylinder 304, and a scale 305. The top surfaces of the rear ends of the two carrier plates 301 are fixedly connected to the bottom surfaces of the two fine-tuning carriers 207. The bottom ends of the two frames 302 are embedded in the top surfaces of the two carrier plates 301 at opposite ends via bearings. The bottom ends of the two bending shafts 303 on the left and right sides are respectively welded to the top surfaces of the two frames 302 at opposite ends. The top surfaces of the two cylinders 304 at opposite ends are hinged to the top surfaces of the two frames 302 at opposite ends via pins, and the top surfaces of the two cylinders 304 at opposite ends are hinged to the top surfaces of the two carrier plates 301 at opposite ends via pins. The ends of the two scales 305 at opposite ends are fixedly connected to the opposite sides of the two carrier plates 301. Figure 1 and Figure 4 As shown, by controlling the start of two cylinders, the start of the two cylinders can drive the two carriers to rotate in opposite directions. The rotation of the two carriers can drive the bending shafts on the left and right sides to rotate simultaneously. By rotating the bending shafts on both sides, the multi-angle bending of the steel bar can be completed quickly. This bending method greatly improves the bending efficiency of U-shaped steel bars.

[0028] Furthermore, the outer wall of the middle section of the fine-tuning shaft 205 is provided with a reverse thread, and the surface of the fine-tuning shaft 205 is threadedly connected to the inner wall of the two fine-tuning holes 204, respectively. Figure 2As shown, the fine-tuning shaft 205 can conveniently control the distance between the two fine-tuning carriers 207.

[0029] Furthermore, the outer walls of the two adjusting rods 211 are respectively threaded to the inner walls of the two adjusting holes 210, such as... Figure 5 As shown.

[0030] Furthermore, both card plates 209 are curved in shape, such as... Figure 5 As shown, the clamping plate 209 can easily hold steel bars of different diameters.

[0031] Furthermore, the stepper motor 206 has the model number FY56EC350AN, such as... Figure 2 As shown.
