Description

Technical Field

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

[0002] Reinforcing steel refers to steel used in reinforced concrete and prestressed reinforced concrete, with a circular cross-section, sometimes square with rounded corners. It includes plain round bars, ribbed bars, and twisted bars. Reinforcing steel for reinforced concrete refers to straight or coiled steel used for reinforcing concrete. Bending reinforcing steel is a technique that changes the angle of the steel bars through mechanical means or heat treatment, mainly used in building structures where the direction of force on the reinforcing steel needs to be changed. An existing steel bar bending device for construction engineering (publication number: CN216656138U) involves placing the steel bar between a positioning rod and a bending rod, and controlling the extension and retraction of an electric actuator. During the extension and retraction of the electric actuator, the extension and retraction of the electric actuator drives a rack to reciprocate. When the rack reciprocates, it drives a gear to rotate in both directions. The turntable rotates synchronously with the gear via a main shaft, facilitating the bending of the steel bar. A battery supplies power to the electric actuator. However, during the bending process, if the lubricating oil cannot be delivered to the bending area quickly and accurately, the area will suffer from insufficient lubrication over a long period, leading to accelerated wear of various components, roughened surfaces, and ultimately affecting the bending accuracy of the steel bar and reducing the finished product qualification rate. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a steel bar bending device for construction engineering.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A steel bar bending device for construction engineering includes a workbench and a metal base. The metal base is fixedly installed on one side of the upper end of the workbench, and a storage box is embedded in the metal base. An installation plate is fixed to the outer wall of the storage box. A support rod is installed in the installation plate through a rotating shaft. An oil nozzle is installed on the support rod through a universal joint hinge. A partition is fixed in the middle section of the storage box. An oil storage tank is provided on one side of the partition, and a miniature oil pump is provided on the other side of the partition. An application tray is provided on the outer side of the storage box, and the application tray is connected to the storage box by an elastic rope.

[0005] As a further embodiment of this utility model, a positioning pin is threadedly installed on the upper end of the mounting plate, a sponge pad is fixed to the bottom end of the application tray, and a locking block is fixed on both outer walls of the storage box. A magnetic block is embedded in each of the two sets of locking blocks, and the locking block is embedded in the inner wall of the metal base.

[0006] As a further embodiment of this utility model, a connecting pipe is fixed between the oil storage tank and the micro oil pump, and the connecting pipe passes through and connects to the partition plate, and the positioning pin passes through and connects to the support rod.

[0007] As a further embodiment of this utility model, a thin hose is fixed between the oil storage tank and the oil injector, a disc is movably provided at the middle of the upper end of the workbench, a positioning post is fixed at the center of the disc, and a bent post is provided on one side of the positioning post.

[0008] As a further embodiment of this utility model, a motor is fixedly installed inside the workbench body, a rotating rod is provided on one side of the motor, the bottom end of the rotating rod is connected to the inner wall of the workbench body through a rotating shaft, and the top end of the rotating rod is fixedly connected to the disc.

[0009] As a further embodiment of this utility model, a driven gear is sleeved on the outer wall of the rotating rod, and a main gear is fixedly installed on the output shaft of the motor, with the main gear meshing with the driven gear.

[0010] Compared with the prior art, the present invention has the following beneficial effects: By setting up a metal base, coating disc, nozzle, and universal joint hinge, the support rod is unfolded and locked with a positioning pin. The universal joint hinge is used to adjust the nozzle to precisely align with the friction area between the positioning post and the bending post. Then, a micro oil pump self-primes oil from the storage tank. The oil is delivered through the connecting pipe and thin hose and sprayed out through the nozzle for lubrication. Under the action of the elastic rope, the coating disc is pulled to make the sponge pad evenly wipe the oil film and absorb excess oil. When not in use, the support rod is fitted and stored on the mounting plate. The sponge pad automatically rebounds to its position under the action of the elastic rope, providing stable lubrication for the bending components, effectively reducing component wear and reducing frictional resistance during rebar bending, which is conducive to improving the quality and efficiency of rebar bending.

[0016] Unfold the support rod 304 on the mounting plate 301 around the pivot. Once the support rod 304 is vertical, insert the positioning pin 305 to lock it in place. Then, adjust the angle of the nozzle 4 using the universal joint hinge 5 to precisely align it with the friction area between the positioning post 103 and the bending post 102. Start the micro oil pump 802, and the oil is delivered to the nozzle 4 and sprayed out through the connecting pipe 7 and the thin hose 306. Then, pull the applicator 201 connected by the elastic rope 203 to wipe the sprayed area with the sponge pad 202. After the oil film is evenly distributed and excess oil is absorbed, the micro oil pump 802 is turned off. The positioning pin 305 is pulled out and the support rod 304 is fitted back into the mounting plate 301. The coating disc 201 is released so that it automatically springs back into place under the action of the elastic rope 203. At this time, the motor 105 in the workbench body 1 is started. The motor 105 drives the main gear 6 to rotate. The main gear 6 meshes with the driven gear 106, which drives the rotating rod 104 and the disc 101 connected to its top to rotate, and the steel bar bending operation can begin.

[0018] Under the elastic tension of the elastic cord 203, the application tray 201 can be flexibly attached to the lubrication area to complete the wiping when pulled. After being released, the application tray 201 and the sponge pad 202 can be automatically pulled back to their original positions. The application tray 201 can also be placed separately in the storage box 3 on one side by hooks, which is more convenient for storage when not in use.

[0019] In this embodiment, a connecting pipe 7 is fixed between the oil storage tank 801 and the micro oil pump 802, and the connecting pipe 7 passes through and connects to the partition plate 8, and the positioning pin 305 passes through and connects to the support rod 304.
