Description

Technical Field

[0001] This invention relates to the field of steel bar processing technology, and in particular to a steel bar bending device with adjustable diameter and adjustable direction. Background Technology

[0002] On construction sites, manual bending of reinforcing bars is often required at special locations such as pile heads and post-cast strips. Currently, three or four workers typically use steel pipes to bend the reinforcing bars with brute force. This method is not only wasteful of manpower and time, but also inefficient. Furthermore, uneven force application during bending poses safety risks. Additionally, since the required bending diameter varies at different locations, manual bending cannot guarantee the accuracy and quality of the bending. Therefore, there is a need for a reinforcing bar bending device with adjustable diameter and direction, which can solve the problems of inefficiency, insufficient bending diameter, and safety hazards associated with manual bending in existing technologies. Summary of the Invention

[0003] The purpose of this invention is to provide a rebar bending device with adjustable diameter and adjustable direction, which can solve the problems of low efficiency, insufficient bending diameter, and safety hazards in the manual bending of rebar in the prior art.

[0004] This invention is implemented as follows:

[0005] An adjustable diameter and adjustable direction rebar bending device includes a movable adjustment bracket, a bending component, and a sliding limit component. The movable adjustment bracket has a frame structure, with a longitudinal groove formed on the top and a vertical groove formed on the side. The sliding limit component is slidably mounted on the movable adjustment bracket along the longitudinal or vertical groove. The bending component is detachably mounted on the sliding limit component, and the rebar passes through the bending component, allowing the rebar to be bent by the bending component.

[0006] The movable adjustment bracket includes casters, first columns, second columns, and a telescopic frame; the upper ends of a pair of first columns are respectively connected to the two ends of one side of the telescopic frame, the upper ends of a pair of second columns are respectively connected to the two ends of the other side of the telescopic frame, and casters are respectively installed at the lower ends of the pair of first columns and the pair of second columns; a longitudinal sliding groove is formed on the top of the telescopic frame, and a vertical sliding groove is formed on one of the second columns.

[0007] The telescopic frame includes longitudinal bars, transverse bars, and telescopic rods; the two ends of the longitudinal bars are respectively fixed vertically to two transverse bars to form a C-shaped structure, and the telescopic rods are also C-shaped, with the transverse bars at both ends of the telescopic rods being inserted into the two transverse bars; one first column and one second column are respectively connected to the bottom of the connection points between the two ends of the longitudinal bars and the two transverse bars; a smooth transition section is provided at one end of the longitudinal bar, at the connection node of one transverse bar and one column, and a smooth transition groove is formed on the smooth transition section, which connects the longitudinal groove and the vertical groove, so that the sliding limiting component can be slidably set in the longitudinal groove or the vertical groove through the smooth transition groove.

[0008] The sliding limiting assembly includes a sliding mechanism, a first limiting rod, and a second limiting rod. Several limiting through holes are formed at intervals on the longitudinal rod and one of the second columns. The first and second limiting rods are vertically inserted into the longitudinal rod or one of the second columns through two of the limiting through holes, respectively. The sliding mechanism is slidably disposed within a longitudinal or vertical groove, with the first and second limiting rods located on opposite sides of the sliding mechanism, thus limiting the sliding mechanism to the longitudinal or vertical groove.

[0009] The sliding mechanism includes a mounting part, a sliding part, and a sliding body; the sliding part is mounted on one surface of the sliding body and is slidably inserted into a longitudinal or vertical groove and located between the first and second limiting rods; a plurality of mounting parts are respectively and spaced apart on the other surface of the sliding body, and mounting holes are formed on the plurality of mounting parts so that the bending component is mounted on the plurality of mounting parts through the mounting holes.

[0010] The sliding part has a cross-shaped structure, and limiting grooves are formed on both sides of the sliding part. The first limiting rod and the second limiting rod are partially engaged in the limiting grooves, so that the sliding part is limited between the first limiting rod and the second limiting rod.

[0011] The bending assembly includes an adjusting rod, a bending handle, a bending mechanism, a rotating shaft, and a bending disc. The bending disc has an inwardly recessed central edge, forming an circumferential groove for the rebar to pass through and bend. The adjusting rod is rotatably mounted on the bending disc, with one end adjustablely inserted into the circumferential groove and pressed against the rebar. The rotating shaft coaxially passes through the bending disc and is fixedly connected to it. One end of the rotating shaft is fixedly connected to several mounting holes of the mounting parts by several fixing bolts. One end of the bending handle is rotatably connected to the other end of the rotating shaft, and the other end of the bending handle extends away from the bending disc. The bending mechanism is mounted on the bending handle and slidably inserted into the circumferential groove, pushing against and rotating the rebar.

[0012] The bending mechanism includes a first diameter limiting member, a second diameter limiting member, a long connecting bolt, a short connecting bolt, a transverse connecting bolt, and a bolt sleeve. One end of the first diameter limiting member and one end of the second diameter limiting member are both semi-restricting rings. When the other end of the first diameter limiting member is connected to the other end of the second diameter limiting member via the transverse connecting bolt, one end of the first diameter limiting member and one end of the second diameter limiting member are joined to form a restricting ring. The outer wall of the bolt sleeve and the inner wall of the restricting ring have a matching polygonal structure, allowing the bolt sleeve to be fitted into the restricting ring. The long connecting bolt passes through the bolt sleeve, and one end of the long connecting bolt is fixedly connected to the bending handle. The outer wall of the bolt sleeve slides against the side edge of the bending disc, causing the edge portion of the restricting ring to be inserted into the circumferential groove and push against the reinforcing bar. The other end of the second diameter limiting member is fixedly connected to the bending handle via the short connecting bolt.

[0013] The bent disc has a threaded through hole in the middle, and an extension screw is screwed through the threaded through hole. An arc-shaped expanded diameter ring is screwed to each end of the extension screw.

[0014] A storage basket is hung on one of the crossbars, and the bending mechanism is placed inside the storage basket after being disassembled.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. This invention, equipped with a bending component, can tighten and fix the reinforcing bar within the circumferential groove by adjusting the screw of the top rod. It is applicable to fixing reinforcing bars of different sizes. The rotation of the bending handle drives the rotation of the limiting ring and pushes the reinforcing bar, causing the reinforcing bar to rotate around the central cylinder of the bending disc to achieve the bending action. Simultaneously, according to the diameter requirements of the bending part of the reinforcing bar, the expansion ring can be installed at the corresponding position by extending the screw, allowing the reinforcing bar to rotate and bend around the expansion ring. This can meet the processing requirements of different bending diameters, has a wide range of applications, a long lever arm for the bending handle, and is simple, labor-saving, and efficient in operation. It reduces the occupation of manpower and time, which helps to reduce construction costs, improve construction efficiency, and eliminate safety hazards.

[0017] 2. Because the present invention is equipped with a sliding limiting component, the bending component can slide into the longitudinal or vertical sliding groove through the longitudinal sliding groove, the smooth transition sliding groove and the vertical sliding groove, and be locked through the limiting through hole by the first limiting rod and the second limiting rod, so as to meet the bending processing requirements of the steel bars in the horizontal or vertical plane, and the operation is highly safe.

[0018] 3. Because the present invention is equipped with a movable adjustment bracket, the lateral dimension of the movable bracket can be adjusted by the telescopic adjustment of the telescopic rod relative to the crossbar, so as to improve the operational safety and stability of the entire device. Furthermore, the entire device can be flexibly moved by the casters, which facilitates the turnover and use of the entire device on the construction site. Attached Figure Description

Detailed Implementation

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] Please see the appendix Figure 1 To be continued Figure 4 An adjustable diameter and adjustable direction rebar bending device includes a movable adjustment bracket, a bending component, and a sliding limit component. The movable adjustment bracket has a frame structure, with a longitudinal groove 8 formed on the top and a vertical groove 9 formed on the side. The sliding limit component is slidably mounted on the movable adjustment bracket along the longitudinal groove 8 or the vertical groove 9. The bending component is detachably mounted on the sliding limit component, and the rebar passes through the bending component, allowing the rebar to be bent by the bending component.

[0037] The movable adjustment bracket facilitates the flexible movement of the entire device on the construction site, resulting in a high turnover rate. At the same time, the stability and safety of the entire device during use can be ensured by adjusting the movable adjustment bracket, so as to meet the processing requirements of different bending diameters of steel bars.

[0038] The bending assembly can slide along the longitudinal groove 8 or the vertical groove 9 via the sliding limit assembly to meet the bending processing operations of the reinforcing bars at different locations, and to make the force on the entire device more balanced and stable during the bending process. The length and width of the longitudinal groove 8 or the vertical groove 9 can be adaptively adjusted according to the actual sliding range.

[0039] The longitudinal chute 8 is located in the horizontal plane, enabling the bending component to bend the steel bars in the horizontal plane. The vertical chute 9 is located in the vertical plane, enabling the bending component to bend the steel bars in the vertical plane. It has high flexibility and is more adaptable to different application scenarios.

[0040] Please see the appendix Figure 1 To be continued Figure 3 The movable adjustment bracket includes casters 101, first columns 201, second columns 202, and a telescopic frame; the upper ends of a pair of first columns 201 are respectively connected to the two ends of one side of the telescopic frame, the upper ends of a pair of second columns 202 are respectively connected to the two ends of the other side of the telescopic frame, and casters 101 are respectively installed at the lower ends of the pair of first columns 201 and the pair of second columns 202; a longitudinal groove 8 is formed on the top of the telescopic frame, and a vertical groove 9 is formed on one of the second columns 202.

[0041] Preferably, the caster wheel 101 can be a caster wheel with a braking function, which can ensure the flexible movement and turnover of the entire device on the construction site, while also locking the entire device by braking, thus ensuring the stability of the entire device during use.

[0042] Preferably, the first column 201, the second column 202, and the telescopic frame can all be made of square steel tubing, and their specific specifications and dimensions can be selected according to the usage requirements. The height of the first column 201 is the same as the height of the second column 202 to ensure that the telescopic frame is located in a horizontal plane.

[0043] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4 The telescopic frame includes a longitudinal rod 601, a transverse rod 602, and a telescopic rod 603. The two ends of the longitudinal rod 601 are respectively vertically fixed to two transverse rods 602 to form a C-shaped structure. The telescopic rod 603 is also C-shaped, and the two transverse rods at both ends of the telescopic rod 603 are inserted into the two transverse rods 602. A first column 201 and a second column 202 are respectively connected to the bottom of the connection points between the two ends of the longitudinal rod 601 and the two transverse rods 602. A smooth transition section 6011 is provided at one end of the longitudinal rod 601, at the connection node between one transverse rod 602 and one column 202. A smooth transition groove 6012 is formed on the smooth transition section 6011, which connects the longitudinal groove 8 and the vertical groove 9, so that the sliding limit component can be slidably installed in the longitudinal groove 8 or the vertical groove 9 through the smooth transition groove 6012.

[0044] The square steel tube of the telescopic rod 603 is slightly smaller than that of the square steel tube of the crossbar 602. The square steel tube of the longitudinal rod 601 is the same as that of the square steel tube of the crossbar 602. This ensures that the telescopic rod 603 can be flexibly inserted and extended relative to the crossbar 602, thereby realizing the size adjustment function of the telescopic frame and ensuring the balance and stability of the entire device during use.

[0045] Please see the appendix Figure 1 To be continued Figure 4 The sliding limiting assembly includes a sliding mechanism, a first limiting rod 701, and a second limiting rod 702. A plurality of limiting through holes 10 are formed at intervals on the longitudinal rod 601 and one of the second columns 202. The first limiting rod 701 and the second limiting rod 702 are vertically inserted into the longitudinal rod 601 or one of the second columns 202 through two of the limiting through holes 10, respectively. The sliding mechanism is slidably disposed within the longitudinal groove 8 or the vertical groove 9, and the first limiting rod 701 and the second limiting rod 702 are located on both sides of the sliding mechanism, thus limiting the sliding mechanism to the longitudinal groove 8 or the vertical groove 9.

[0046] Preferably, the first limiting rod 701 and the second limiting rod 702 can be made of reinforcing steel bars, and the limiting through hole 10 has a diameter slightly larger than that of the reinforcing steel bar to facilitate the insertion and removal of the first limiting rod 701 and the second limiting rod 702. By inserting the first limiting rod 701 and the second limiting rod 702 on both sides of the sliding mechanism, the sliding of the sliding mechanism along the longitudinal slide groove 8 or the vertical slide groove 9 can be restricted, preventing accidental sliding during the bending operation of the reinforcing steel bar.

[0047] Please see the appendix Figure 11 To be continued Figure 14 The sliding mechanism includes a mounting part 4011, a sliding part 4012, and a sliding body 4013. The sliding part 4012 is mounted on one surface of the sliding body 4013 and is slidably inserted into the longitudinal slide groove 8 or the vertical slide groove 9 and located between the first limiting rod 701 and the second limiting rod 702. A plurality of mounting parts 4011 are respectively installed at intervals on the other surface of the sliding body 4013, and each of the plurality of mounting parts 4011 has a mounting hole 4015, so that the bending component is mounted on the plurality of mounting parts 4011 through the mounting hole 4015.

[0048] Preferably, the mounting part 4011, the sliding part 4012, and the sliding body 4013 can be integrally formed from steel. The sliding part 4012 has a cross-shaped structure, which facilitates stable sliding within the longitudinal groove 8 or the vertical groove 9 without detaching. The sliding body 4013 consists of a cylindrical base and a cross-shaped support, which provides stable support for the bending component and ensures that the bending component is firmly installed. Four mounting parts 4011 can be provided, evenly distributed at the edges of the sliding body 4013, for fitting and connecting with the bending component, making the assembly and disassembly of the bending component convenient and quick.

[0049] Please see the appendix Figure 11 To be continued Figure 14 The sliding part 4012 has a cross-shaped structure, and limiting grooves 4014 are formed on both sides of the sliding part 4012. The first limiting rod 701 and the second limiting rod 702 are partially engaged in the limiting grooves 4014, so that the sliding part 4012 is limited between the first limiting rod 701 and the second limiting rod 702.

[0050] Preferably, the limiting groove 4014 can adopt a semi-circular structure with the same diameter as the first limiting rod 701 and the second limiting rod 702, which facilitates the locking and limiting of the first limiting rod 701 and the second limiting rod 702, and improves the limiting reliability of the first limiting rod 701 and the second limiting rod 702 on the sliding part 4012.

[0051] Please see the appendix Figure 5 To be continued Figure 8 The bending assembly includes an adjusting rod 301, a bending handle 302, a bending mechanism, a rotating shaft 304, and a bending disc 305. The bending disc 305 has an inwardly recessed central edge, forming an annular groove 3051 for the rebar to pass through and bend. The adjusting rod 301 is rotatably mounted on the bending disc 305 via an adjusting nut 3011, allowing one end of the adjusting rod 301 to be adjustablely inserted into the annular groove 3051 and pressed against the rebar. The rotating shaft 304 coaxially passes through the bending disc 305. Shaft 304 is fixedly connected to bending disc 305 by locking nut 308. One end of shaft 304 is fixedly connected to mounting holes 4015 of mounting parts 4011 by several fixing bolts 3041. One end of bending handle 302 is rotatably connected to the other end of shaft 304. The other end of bending handle 302 extends away from bending disc 305. Bending mechanism is installed on bending handle 302. Bending mechanism is slidably inserted into circumferential groove 3051 and pushes against rotating steel bar.

[0052] Preferably, the bending disc 305 is formed by an upper disc, a middle cylinder, and a lower disc coaxially connected from top to bottom. The diameter of the middle cylinder is smaller than the diameters of the upper and lower discs, thus forming an circumferential groove 3051 between the upper disc, the middle cylinder, and the lower disc. The adjusting rod 301 can be a screw. An adjusting nut 3011 is fixedly installed at the edge of the upper and lower discs. By rotating the thread between the adjusting rod 301 and the adjusting nut 3011, the adjusting rod 301 can be pushed into the circumferential groove 3051 to tighten the reinforcing bar onto the middle cylinder, or the adjusting rod 301 can be unscrewed out of the circumferential groove 3051 to facilitate the removal of the bent reinforcing bar.

[0053] The bending handle 302 can rotate around the rotating shaft 304, driving the bending mechanism to rotate synchronously. In the initial state, the bending mechanism is located beside the adjusting rod 301. As the bending handle 302 rotates, it drives the bending mechanism to rotate synchronously, pushing the steel bar and causing the steel bar to rotate and bend around the central cylinder of the bending disc 305. The length of the bending handle 302 can be adapted to the usage requirements to extend the lever arm and make the operation more time-saving and labor-saving.

[0054] Preferably, the adjusting rod 301, bending handle 302, bending mechanism, rotating shaft 304 and bending disc 305 are all made of steel, which has high structural strength and is not easy to bend or deform.

[0055] Please see the appendix Figure 5 To be continued Figure 8 The bending mechanism includes a first diameter limiting member 3031, a second diameter limiting member 3032, a long connecting bolt 3061, a short connecting bolt 3062, a transverse connecting bolt 3063, and a bolt sleeve 307. One end of the first diameter limiting member 3031 and one end of the second diameter limiting member 3032 are both semi-restricting rings. When the other end of the first diameter limiting member 3031 is connected to the other end of the second diameter limiting member 3032 via the transverse connecting bolt 3063, one end of the first diameter limiting member 3031 and one end of the second diameter limiting member 3032 are joined to form a restricting ring. The outer wall of the bolt sleeve 307 and the inner wall of the limiting ring are in a matching polygonal structure, so that the bolt sleeve 307 is fitted into the limiting ring. The long connecting bolt 3061 passes through the bolt sleeve 307 and one end of the long connecting bolt 3061 is fixedly connected to the bending handle 302. The outer wall of the bolt sleeve 307 slides against the side edge of the bending disc 305, so that the edge part of the limiting ring is inserted into the circumferential groove 3051 and pushes against the reinforcing bar. The other end of the second diameter limiting member 3032 is fixedly connected to the bending handle 302 by the short connecting bolt 3062.

[0056] Preferably, the inner wall of the limiting ring and the outer wall of the bolt sleeve 307 are both hexagonal structures, which can limit the relative rotation of the limiting ring and the bending handle 302 and ensure the synchronization of rotation. At the same time, the limiting ring is connected and fixed to the bending handle 302 by the long connecting bolt 3061 and the bolt sleeve 307, and the second diameter limiting member 3032 is connected and fixed to the bending handle 302 by the short connecting bolt 3062, further ensuring that the bending handle 302 rotates synchronously with the limiting ring.

[0057] The outer wall of the limiting ring is circular, which can push against the reinforcing bar. The small contact area between the ring and the reinforcing bar results in low frictional resistance, ensuring the rotation and bending of the reinforcing bar.

[0058] Please see the appendix Figure 9 and attached Figure 10 The bent disc 305 has a threaded through hole 3052 in the middle, and an extension screw 3091 is screwed through the threaded through hole 3052. An arc-shaped expanded diameter ring 3092 is screwed to both ends of the extension screw 3091.

[0059] The length of the extension screw 3091 can be adapted to the actual use requirements and is used to install the expansion ring 3092. The diameter of the expansion ring 3092 can be adapted to the actual use requirements, thereby increasing the diameter of the central cylinder, so that the steel bar can be bent around the expansion ring 3092, which is used for bending large-diameter steel bars.

[0060] Please see the appendix Figure 1 To be continued Figure 4 A storage basket 501 is hung on one of the crossbars 602, and the bending mechanism is placed inside the storage basket 501 after being disassembled.

[0061] The storage basket 501 is suspended on the outside of the movable adjustment bracket and is used to place the bending mechanism for easy storage.

[0062] Please see the appendix Figure 15 The entire device can be prefabricated in the factory and transported to the construction site. After acceptance, it can be put into use to bend steel bars.

[0063] Please see the appendix Figure 1 To be continued Figure 14 The method of use and working principle of this invention are as follows:

[0064] The entire device is moved to the construction position via casters 101, and the casters 101 are locked and braked. The telescopic rod 603 is extended and slid relative to the two crossbars 602 according to actual usage requirements to adjust the size of the telescopic frame. After adjustment, the telescopic rod 603 and the two crossbars 602 can be locked and fixed with bolts to ensure the stability of the entire device during use.

[0065] When bending the reinforcing bar in the horizontal plane, the sliding mechanism is slid along the longitudinal groove 8 to the appropriate position and locked. When bending the reinforcing bar in the vertical plane, the sliding mechanism is slid along the longitudinal groove 8 through the smooth transition groove 6012 to the appropriate position of the vertical groove 9 and locked. The sliding locking method of the sliding mechanism is as follows: the cross-shaped sliding part 4012 slides along the longitudinal groove 8, the smooth transition groove 6012, or the vertical groove 9. After sliding to the position, the first limiting rod 701 and the second limiting rod 702 are respectively inserted into the two limiting through holes 10 on both sides of the sliding part 4012, and the first limiting rod 701 and the second limiting rod 702 are partially embedded in the limiting groove 4014, thus locking and positioning the sliding part 4012.

[0066] The bending assembly is secured to the mounting holes 4015 of the four mounting parts 4011 via the pivot 304 and four fixing bolts 3041, so that the bending assembly is fixed on the sliding body 4013. The circumferential groove 3051 is located in the horizontal plane for bending the steel bars in the horizontal plane, or the circumferential groove 3051 is located in the vertical plane for bending the steel bars in the vertical plane.

[0067] The other ends of the first diameter limiting member 3031 and the second diameter limiting member 3032 are spliced ​​together by a horizontal connecting bolt 3063. One end of the first diameter limiting member 3031 and one end of the second diameter limiting member 3032 are spliced ​​together to form a limiting ring and clamp the threaded sleeve 307. The long connecting bolt 3061 is screwed and fixed inside the threaded sleeve 307. The upper end of the long connecting bolt 3061 is fixedly connected to the middle of the bending handle 302 by a nut, so that the outer wall of the threaded sleeve 307 slides against the side wall of the bending disc 305. The other end of the second diameter limiting member 3032 is reinforcedly connected to the middle of the bending handle 302 by a short connecting bolt 3062 and a nut. The edge of the limiting ring is embedded in the circumferential groove 3051, and the limiting ring is rotated to the side of the adjusting rod 301 by the bending handle 302 around the rotating shaft 304.

[0068] For small-diameter bent steel bars: Pass the steel bar through the circumferential groove 3051, rotate the adjusting rod 301, and use the threaded transmission between the adjusting rod 301 and the adjusting nut 3011 to screw the adjusting rod 301 into the circumferential groove 3051 and tighten it on the steel bar, so that the steel bar and the bending disc 305 are relatively fixed; rotate the bending handle 302, so that the limiting ring rotates synchronously with the bending handle 302 and pushes against the steel bar, so that the steel bar is bent with the central cylinder of the bending disc 305 as the bending part.

[0069] For large-diameter bent reinforcing bars: An extension screw 3091 is screwed into the threaded through hole 3052, and expansion rings 3092 are screwed into both ends of the extension screw 3091. The diameter of the central cylinder of the bending disc 305 is increased by the expansion rings 3092. Subsequently, the reinforcing bar is bent using the same operation as for small-diameter bent reinforcing bars, with the expansion rings 3092 as the bending point. After bending the large-diameter reinforcing bar, the arc diameter of the bending point is larger than that of the small-diameter bent reinforcing bar.

[0070] The bending operation of steel bars in both horizontal and vertical planes is the same, and will not be described in detail here.

[0071] After the steel bar is bent, the bending assembly is removed from the mounting part 4011 and placed in the storage basket 501 for easy storage and carrying.

[0072] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the invention. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
