Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a digital display and control device for the bending angle of reinforcing bars. Background Technology

[0002] The bending angle of steel bars refers to the angle at which steel bars are bent during processing. It is used to meet the structural requirements such as the shape of components and anchorage. Common bending angles include 90° and 135°. Different angles correspond to different specifications. For example, the bending angle of steel bars at beam-column joints must meet the design and construction standards to ensure the structural stress performance.

[0003] A search revealed that the document with publication number "CN217166237U" mentions "This utility model relates to a device for measuring the bending angle of a reinforcing bar, characterized in that: it includes: a laser pointer and a measuring disk for measuring the bending angle of the reinforcing bar; one side of the laser pointer is fixed with a first fixing member and a second fixing member for fixing the laser pointer to the reinforcing bar to be measured; the measuring disk is a disc-shaped structure, and the edge of the measuring disk is marked with angle scale lines." In use, during measurement, the laser pointer can be placed on the measuring disk, and the bending angle of the reinforcing bar can be read through the laser beam emitted by the laser pointer.

[0004] However, in construction engineering, the bending of steel bars is a common and important process. Traditional steel bar bending devices usually rely on manual experience and simple mechanical structures to control the bending angle, lacking precise angle measurement and display functions. This can easily lead to bending angles exceeding the bending requirements, thus affecting the quality of steel bar bending. Furthermore, in some building structures with high requirements for steel bar bending angles, such as at the joints of frame structures, traditional devices cannot meet the precise bending angle requirements, which can easily lead to weak steel bar connections and affect the safety and stability of the building structure.

[0005] Therefore, we provide a digital display control device for the bending angle of steel bars to solve the above problems. Utility Model Content

[0015] As a further description of the above technical solution:

[0016] The rotating encoder disk is electrically connected to the angle display, and the rotating encoder disk is electrically connected to the angle sensor. The angle sensor rotates along the rotating encoder disk via a rotating bearing.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This utility model, by setting up a rebar bending component, a bending arc adjustment column, a rebar limiting plate, and a bending angle auxiliary component, allows for adjustment of the bending angle of the rebar by adjusting the sleeve thickness of the bending arc adjustment column when needed, thus adapting to the requirements of different specifications of rebar. Based on the number of layers of bending arc adjustment columns used during the rebar bending process, the bending rod can be adjusted to the corresponding position to ensure accurate relative positioning between the bending rod and the rebar limiting plate. The rebar limiting plate is inserted into the corresponding hole according to the number of layers of bending arc adjustment columns to cooperate with the bending rod, preventing deviation during rebar bending and ensuring bending accuracy. When the rebar is bent along the bending arc adjustment column, a bending angle push plate of the corresponding diameter is inserted into the slot according to the number of layers of bending arc adjustment columns.

This not only protects the rotating bearing as a whole, but also serves as a load-bearing interface, ensuring that the angle sensor accurately measures the bending angle as the rotating bearing rotates. As the bending rod clamps the steel bar and bends it, the angle sensor rotates synchronously with the rotating bearing and along the rotating encoder disk. Due to the concentric design of the rotating encoder disk and the rotating bearing, the angle sensor can accurately capture the travel path of the rotating encoder disk during the bending process.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 As shown, this utility model provides a technical solution: a digital display control device for the bending angle of a rebar, including a rebar bending base plate 1, a rebar bending assembly 2 disposed on the upper side of the rebar bending base plate 1, the rebar bending assembly 2 including a bending force column 201 welded to the center of the upper side of the rebar bending base plate 1, a rotary bearing 203 disposed at the lower outer end of the bending force column 201, an outer shaft cover plate 204 disposed on the upper side of the rotary bearing 203, an angle sensor 205 welded to the left side of the outer shaft cover plate 204, an adjustment bolt hole 206 welded to the upper side of the outer shaft cover plate 204, a bending rotary rod 207 installed on the left side of the adjustment bolt hole 206, a rotary encoder disk 208 disposed on the outer side of the rotary bearing 203, an angle display 209 disposed on the front side of the rebar bending base plate 1, an insertion hole 210 disposed on the right side of the rotary encoder disk 208, a rebar limiting plate 211 disposed on the upper side of the insertion hole 210, and a bending angle auxiliary assembly 3 disposed on the rear side of the rebar bending base plate 1.

[0033] Furthermore, the outer slot of the bent load-bearing column 201 is connected to a bending arc adjustment column 202. The bending arc adjustment column 202 is arranged in four sets of sleeves. When needed, the bending angle of the steel bar can be adjusted by adjusting the sleeve thickness of the bending arc adjustment column 202 to meet the needs of steel bars of different specifications.

[0034] Furthermore, the outer shaft cover plate 204 is welded to the outer layer of the rotary bearing 203. The outer shaft cover plate 204 covers the upper side of the rotary bearing 203. The outer shaft cover plate 204 drives the angle sensor 205 to rotate through the rotary bearing 203. When needed, the inner wall of the rotary bearing 203 is welded to the steel bending base plate 1 to form a whole, while the outer wall of the rotary bearing 203 is welded to the outer shaft cover plate 204. This not only protects the rotary bearing 203 as a whole, but also serves as a load-bearing interface, ensuring that the angle sensor 205 accurately measures the bending angle as the rotary bearing 203 rotates.

[0035] Furthermore, the bending rod 207 and the adjusting bolt hole 206 are connected by a slot. The bending rod 207 and the adjusting bolt hole 206 form a rotating structure through the rotating bearing 203. The bending rod 207 and the rebar limiting plate 211 bend the rebar through the bending force column 201. When needed, the bending rod 207 can be adjusted to the adjusting bolt hole 206 to the corresponding position according to the number of layers of the bending arc adjusting column 202 used in the rebar bending process, so as to ensure the accurate relative position of the bending rod 207 and the rebar limiting plate 211.

[0036] Furthermore, the rotary encoder 208 is electrically connected to the angle display 209, and the rotary encoder 208 is electrically connected to the angle sensor 205. The angle sensor 205 rotates along the rotary encoder 208 via the rotary bearing 203. The rotary encoder 208 and the angle sensor 205 are located at the same center, forming a magnetoelectric sensing structure. When needed, as the bending rod 207 bends the steel bar, the angle sensor 205 rotates synchronously with the rotation of the rotary bearing 203 and rotates along the rotary encoder 208. Due to the concentric design of the rotary encoder 208 and the rotary bearing 203, the angle sensor 205 can accurately capture the path of the rotary encoder 208 during the bending process.

[0037] Furthermore, the rebar limiting plate 211 and the insertion hole 210 are connected by a slot. There are four sets of insertion holes 210, and the positions of the insertion holes 210 correspond one-to-one with the bending curvature adjustment column 202. When needed, the rebar limiting plate 211 is inserted into the corresponding insertion hole 210 according to the number of layers of the bending curvature adjustment column 202, so as to cooperate with the bending rod 207, avoid the rebar from deviating during the bending process, and ensure bending accuracy.

[0038] Furthermore, the bending auxiliary component 3 includes a hydraulic rod 301 welded to the upper rear side of the reinforcing bar bending base plate 1. A slot 302 is welded to the end of the hydraulic rod 301. A bending angle push plate 303 is connected to the inner side of the slot 302. The bending angle push plate 303 and the bending arc adjustment column 202 are connected by a slot. When the reinforcing bar is bent along the bending arc adjustment column 202, the bending angle push plate 303 of the corresponding diameter is selected according to the number of layers of the bending arc adjustment column 202 and inserted into the slot 302. At this time, the hydraulic rod 301 pushes the bending angle push plate 303 to precisely press the reinforcing bar towards the bending arc adjustment column 202 to ensure that the bending angle is consistent with the preset angle.

[0039] Working principle: When needed, first place the rebar bending base plate 1 in the required position. Then, according to the required bending angle, select an appropriate number of bending angle adjustment columns 202 and fit them onto the outside of the bending force column 201. After preparation, according to the number of bending angle adjustment columns 202, insert the rebar limiting plate 211 into the corresponding insertion hole 210 and insert the bending rod 207 into the corresponding adjustment bolt hole 206. After preparation, insert the rebar into the inner side of the rebar limiting plate 211 and the bending rod 207. As the bending rod 207 is manually turned, the bending rod 207 will move along the outer shaft cover plate 204. The rotary bearing 203 rotates, and the angle sensor 205 rotates along with the outer shaft cover plate 204 and along the rotary encoder disk 208 to calculate the bending angle. The bending angle is then displayed in real time via the angle display 209. During the bending process of the rebar, the corresponding bending angle push plate 303 is selected and inserted into the slot 302 according to the number of layers of the bending arc adjustment column 202. Then, the hydraulic rod 301 pushes the bending angle push plate 303 to bring the rebar into contact with the surface of the bending arc adjustment column 202, ensuring that the bending angle is accurate. This completes the use of a digital display control device for the rebar bending angle.
