Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and more specifically, to a rebar straightening device for building construction. Background Technology

[0002] Building construction is a complex and systematic project, encompassing multiple stages from foundation construction to main structure erection and decoration. In this process, steel reinforcement, as an indispensable building material, is widely used to construct the building's framework due to its high strength, good toughness, and durability. It provides stable support for the building, ensuring its safety and stability under various loads.

[0003] On construction sites, short steel bars may bend and deform during handling and storage due to various reasons. If these short steel bars are not straightened during subsequent construction, they will affect the dimensional accuracy and load-bearing capacity of the building structure. Existing steel bar straightening devices are prone to damage from the guides used to guide the short steel bars into the straightening rollers when straightening them. Traditional guides are often bolted to the front face of the straightening roller, or are an integral design where multiple guides of different sizes are welded to a front baffle. If a guide is damaged, the former requires cumbersome removal and replacement, while the latter requires complete disassembly and replacement, wasting resources and time on disassembly and installation. Therefore, we propose a steel bar straightening device for building construction. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a steel bar straightening device for building construction, so as to solve the technical problem that the guide in the existing steel bar straightening device is easily scratched and damaged by the steel bar, and the process of dismantling and replacing it after damage is cumbersome.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a steel bar straightening device for building construction, including a base, a frame arranged at one end of the upper surface of the base, a roller pressing mechanism A arranged at the front end inside the frame, a roller pressing mechanism B arranged at the rear end inside the frame, a horizontal plate arranged in the middle of the front surface outside the frame, and a guide mechanism arranged inside the horizontal plate.

[0006] The guiding mechanism includes a cylinder A, with a cylinder B inserted into one end of the cylinder A. A block is arranged on the outside of the cylinder B. The block passes through the insertion port and is rotated and locked in the bayonet slot. Both the insertion port and the bayonet slot are located within a limiting block, which is arranged in the middle of the inside of the cylinder A.

[0007] Preferably, a drive motor is arranged at the other end of the upper surface of the base, and the output end of the drive motor is poweredly connected to the roller pressing mechanism A and the roller pressing mechanism B through a transmission belt.

[0008] Preferably, the roller pressing mechanism A includes rollers A, and there are two rollers A arranged in parallel at the front end of the frame. The rollers A are provided with notches spaced apart from left to right.

[0009] Preferably, the rolling mechanism B includes two rollers B, which are arranged in parallel vertically at the rear end of the frame. A grooved plate is arranged below the rollers B and is fixed to the bottom end of the rear surface of the frame.

[0010] Preferably, a spring piston is arranged at the other end of the cylinder A, and a stop plate is arranged at the head end of the spring piston, the surface of the stop plate being tangent to the surface of one end of the cylinder B.

[0011] Preferably, the cylinder B is provided with a funnel-shaped channel, which is plated with chromium metal material.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the design of the insert block, insertion port, and bayonet structure, allows the insert block installed at one end of the cylinder B to pass through the insertion port after the cylinder B is inserted into the cylinder A. After passing through, the operator needs to rotate the cylinder B, causing the insert block at one end of the cylinder B to move away from the insertion port and lock into the bayonet. At this point, the cylinder B and the cylinder A are fixedly connected. This rotating and locking connection facilitates initial installation and subsequent disassembly. When the cylinder B is worn or even damaged due to long-term straightening of the reinforcing bars, it is easy for the operator to quickly replace it. Through the design of the spring piston and the abutment plate structure, when the cylinder B, with the insert block installed at one end, passes through the limiting block and abuts against its surface, it can elastically buffer the block, leaving room for rotation. When the cylinder B, with the insert block, rotates and locks into the bayonet, the spring piston will push the abutment plate to tightly abut against one end of the cylinder B, limiting the insert block locked in the bayonet and preventing the insert block from automatically disengaging from the bayonet without manual force.

[0014] 2. This utility model designs roller A and a notch structure. There are two rollers A, each with a notch. Since the two rollers A are arranged vertically and parallel, the two notches form a circular hole. The reinforcing bar, guided by the guiding mechanism, is inserted into this circular hole. The reinforcing bar is then pulled into the hole by the two rotating rollers A, achieving the effect of actively dragging the reinforcing bar within the guiding mechanism and roller B. By designing roller B and a grooved plate structure, after the reinforcing bar is straightened by the guiding mechanism and pressed by the rolling mechanism A, it can pass between the two rollers B. The two rollers B provide the final auxiliary correction for the reinforcing bar. Both ends of the two rollers B are connected to the frame through buffers, which allows for flexible adaptation of reinforcing bars of different sizes to enter between the two rollers B, allowing the two rollers B to clamp and crush them. Finally, the corrected reinforcing bar falls into the inclined grooved plate, which guides and transports it away.

[0015] 3. The cylinder B of this utility model has a channel inside. The channel is designed so that the reinforcing bar can pass through it. The funnel-shaped structure is designed to make it easier for the reinforcing bar to enter the inside, which has a guiding effect. The internal chrome plating is for wear resistance. Chromium metal has the advantages of high hardness and good lubricity. Since the reinforcing bar passing through the channel for a long time will inevitably be damaged by friction, the chrome plating is also to extend the service life of the cylinder B.

Detailed Implementation

[0024] like Figures 1 to 6 As shown, the present invention relates to a steel bar straightening device for building construction, including a base 1, a frame 2 arranged at one end of the upper surface of the base 1, a roller pressing mechanism A3 arranged at the front end inside the frame 2, a roller pressing mechanism B4 arranged at the rear end inside the frame 2, a horizontal plate 5 arranged in the middle of the front surface outside the frame 2, and a guide mechanism 6 arranged inside the horizontal plate 5.

[0025] The guiding mechanism 6 includes a cylinder A601, a cylinder B602 inserted into one end of the cylinder A601, and an insert block 603 arranged at the other end of the cylinder B602. The insert block 603 passes through the insertion port 604 and is rotated and locked in the slot 605. Both the insertion port 604 and the slot 605 are located in the limiting block 606, which is arranged in the middle of the inside of the cylinder A601. This utility model, through the design of the insert block 603, the insertion port 604, and the locking slot 605, allows the insert block 603 installed at one end of the cylinder B602 to pass through the insertion port 604 after the cylinder B602 is inserted into the cylinder A601. After passing through, the operator needs to rotate the cylinder B602, so that the insert block 603 installed at one end of the cylinder B602 will be removed from the insertion port 604 and locked in the locking slot 605. At this time, the cylinder B602 and the cylinder A601 are fixedly connected. This rotating and locking connection facilitates the initial installation and subsequent disassembly. When the cylinder B602 is worn or even damaged due to long-term straightening of the reinforcing bars, it is easy for the operator to quickly replace it.

[0026] In an embodiment of this invention, a drive motor 7 is arranged at the other end of the upper surface of the base 1. The output end of the drive motor 7 is connected to the roller pressing mechanism A3 and the roller pressing mechanism B4 via a transmission belt 8. By designing the structure of the drive motor 7 and the transmission belt 8, this invention enables the rollers A301 and B401 to rotate, thus achieving the effect of power output.

[0027] In an embodiment of this utility model, the rolling mechanism A3 includes two rollers A301, which are arranged vertically and parallel to each other at the front end of the frame 2. Each roller A301 has a notch 302 spaced apart from left to right. By designing the roller A301 and notch 302 structure, this utility model provides two rollers A301, each with a notch 302. Because the two rollers A301 are arranged vertically and parallel, the two notches 302 form a circular hole. A reinforcing bar, inserted through the guide mechanism 6, is then inserted into this circular hole. The reinforcing bar is then pulled into the hole by the two rotating rollers A301, achieving the effect of actively dragging the reinforcing bar within the guide mechanism 6 and roller B401.

[0028] In this embodiment of the invention, the roller pressing mechanism B4 includes two rollers B401 arranged vertically and parallel to each other at the rear end of the frame 2. A grooved plate 9 is arranged below the rollers B401 and fixed to the bottom of the rear surface of the frame 2. By designing the rollers B401 and the grooved plate 9, this invention allows the reinforcing bars, after being straightened by the guiding mechanism 6 and pressed by the roller pressing mechanism A3, to pass between the two rollers B401. The two rollers B401 provide a final auxiliary straightening step for the reinforcing bars. Both ends of the two rollers B401 are connected to the frame 2 via buffers, allowing for flexible adaptation of reinforcing bars of different sizes to enter between them. The rollers B401 can clamp and press the reinforcing bars, and finally, the straightened reinforcing bars fall into the inclined grooved plate 9, where they are guided and transported away.

[0029] In an embodiment of this invention, a spring piston 607 is arranged at the other end of the cylinder A601, and a stop plate 608 is arranged at the head end of the spring piston 607. The surface of the stop plate 608 is tangent to the surface of one end of the cylinder B602. By designing the structure of the spring piston 607 and the stop plate 608, this invention allows for elastic buffering when the cylinder B602, with the insert 603 installed at one end, passes through the limiting block 606 and abuts against its surface. After buffering the insert 603, it leaves room for rotation. When the cylinder B602, with the insert 603, rotates and engages with the slot 605, the spring piston 607 pushes the stop plate 608 to press tightly against one end of the cylinder B602, limiting the insert 603 engaged in the slot 605 and preventing the insert 603 from automatically disengaging from the slot 605 without manual force.

[0030] In an embodiment of this invention, the cylinder B602 is provided with a funnel-shaped channel, the inside of which is plated with chromium metal. The channel within the cylinder B602 is designed to allow reinforcing bars to pass through, and the funnel shape facilitates easier entry of the bars, acting as a guide. The chromium plating is for wear resistance; chromium metal has advantages such as high hardness and good lubricity. Since reinforcing bars passing through the channel for extended periods will inevitably suffer frictional damage, the chromium plating also extends the service life of the cylinder B602.

[0031] Working Principle: This embodiment provides a rebar straightening device for building construction. When using it, the operator first needs to connect an external power supply to the device and control its operation via a control panel. The operator starts the drive motor 7, which directly drives the roller A301 connected to the output end. The rotation of one roller A301 will cause the other roller A301, which is in contact with it, to rotate as well. Simultaneously, the drive motor 7 also drives roller B401 to rotate via a transmission belt 8. The rotation of one roller B401 will cause the other roller A301, which is in contact with it, to rotate as well. Another roller B401 rotates. After rollers A301 and B401 rotate, the worker inserts the bent short steel bar to be straightened into the guide mechanism 6, which matches the specified size. When the steel bar is inserted into the cylinder B602 within the guide mechanism 6, it is guided by the funnel-shaped channel to pass through the slot between the limiting block 606, the abutment plate 608, and the cylinder A601. Through the slot, one end of the steel bar first contacts the space between the two rollers A301, and is pulled in by the rotation of the two rollers A301. The pulled-in steel bar is then... The steel bar will be straightened by cylinder B602, then rolled and corrected by two rollers A301. Finally, the steel bar will be transferred through notch 302 to the space between two rollers B401 for further straightening and then placed on the channel plate 9, which will guide and transport it away. Cylinder B602 in the guiding mechanism 6 may be damaged due to prolonged contact with the steel bar. After a certain period of time, it will be damaged and need to be replaced by staff. The specific replacement operation is that the staff pinches cylinder B602 and applies pushing force. At this time, cylinder B602 will move against the inside of cylinder A601. The stop plate 608 is used to release the limiting position of the insert 603, which is stuck in the slot 605. At this time, the operator rotates the cylinder B602 to move the insert 603 from the slot 605 to the slot 604. In this way, the insert 603 can be released through the slot 604, completing the separation of the cylinder B602 from the cylinder A601. Finally, the operator replaces the cylinder B602 with a new one and installs it in the cylinder A601. The utility model can then be used normally. The installation steps can be reversed by following the above disassembly steps.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
