Description

Technical Field

[0001] This utility model relates to the field of steel bar production and processing technology, and in particular to a steel bar braking and releasing device. Background Technology

[0002] In the process of straightening reinforcing bars, the bars need to be placed on a feed reel. A traditional feed reel consists of a base, a rotating shaft mounted on the base, and a cylindrical feed reel enclosed by a fixed plate. The feed reel rotates around the shaft, driven by the reinforcing bar, allowing for the feeding and storage of the bars. This type of feed reel generally lacks a braking device and a guide wire mechanism. In subsequent processes, when reinforcing bars are needed, the feed reel cannot rotate actively; it relies on pulling the bars placed on it to rotate. When no reinforcing bars are needed, the feed reel takes a long time to come to a stop, lacking active braking, which can lead to the reinforcing bars becoming loose or excessively released. Utility Model Content

[0021] In some embodiments, the wear-resistant joint assembly includes:

[0022] A wear-resistant joint mounting base, one end of which is fixedly connected to the first column, and the other end of which is provided with a first half-wear-resistant joint;

[0023] The upper pressure block is provided with a second half wear-resistant opening. The upper pressure block is rotatably installed on the wear-resistant opening mounting seat. The openings of the first half wear-resistant opening and the second half wear-resistant opening are opposite to each other and can be interlocked to form a first wear-resistant opening. The reinforcing bar can be inserted into the first wear-resistant opening.

[0024] A buckle, the two ends of which are respectively connected to the upper pressure block and the wear-resistant port mounting seat to lock the first wear-resistant port.

[0025] In some embodiments, the wear-resistant mounting base is further provided with a second wear-resistant port.

The second wear-resistant ports on the latter wear-resistant port assembly are coaxially arranged with the first or second wear-resistant ports on the former wear-resistant port assembly. The reinforcing bar passes through the plurality of coaxially arranged first and second wear-resistant ports.

The wire-laying columns are fixedly connected to the turntable through connecting plates. The wire-laying columns are used to wind and install rebars, and the turntable is used to support the rebars. By actively controlling the rotation of the wire-laying columns through the drive assembly, the release speed of the rebars can be controlled, avoiding excessively fast wire laying due to gravity or inertia, reducing manual intervention, and improving efficiency. The drive assembly stabilizes the wire-laying process, reducing length or displacement deviations caused by uneven wire-laying speeds, ensuring that the rebar arrangement meets design requirements. By setting multiple wire-laying frames and paired first guide wire mechanisms on the frame, the guide wire mechanisms can guide the rebars on the columns to the feeding position of the next process (such as a straightening machine or bending machine). Multiple wire-laying frames can be used for rebars of different diameters and strengths, providing strong versatility and synchronous feeding, thus improving feeding efficiency.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0055] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0056] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0057] This utility model provides a rebar braking and releasing device for realizing active braking and releasing and winding of rebar.

[0058] like Figures 1-12As shown, the rebar braking and wire-laying device includes a frame 1, a wire-laying frame 2, and a first conductor mechanism 3. The frame 1 extends along a first direction (X direction). Multiple wire-laying frames 2 are provided and spaced apart on the frame 1 along the first direction. The wire-laying frame 2 includes a wire-laying base 201, a drive assembly 202, a main shaft 203, a turntable 204, a wire-laying column 205, and a connecting plate 208. The wire-laying base 201 is fixed on the frame 1, and the drive assembly 202 is disposed on the wire-laying base 201. The output end of the drive component 202 is connected to the main shaft 203 to drive the main shaft 203 to rotate. The bottom ends of multiple wire feeding columns 205 are fixedly connected to the turntable 204. The multiple wire feeding columns 205 are fixedly connected to the main shaft 203 through the connecting plate 208. The reinforcing bar can be wound around the multiple wire feeding columns 205 and supported on the turntable 204. Multiple first wire guiding mechanisms 3 are provided. Multiple first wire guiding mechanisms 3 are arranged in pairs with multiple wire feeding frames 2. One end of the reinforcing bar is inserted through the first wire guiding mechanism 3 and led out.

[0059] by Figure 1 and Figure 2 As shown in the example, the frame 1 is a frame structure. Four wire feeding frames 2 are arranged sequentially on the frame 1 along the first direction. Each wire feeding frame 2 is paired with a first conductor mechanism 3. Along the positive direction of the X direction, the steel bars on the first wire feeding frame 2 are led out through the paired first conductor mechanism 3 for the next process. A patterned plate 11 is provided on the frame 1 to cover the upper surface of the frame 1.

[0060] The rebar braking and releasing device provided by this utility model drives the main shaft 203 to rotate via a drive assembly 202. The main shaft 203 is connected to multiple releasing columns 205 via a connecting plate 208, causing the multiple releasing columns 205 to rotate around the main shaft 203. The multiple releasing columns 205 are used to wind and install rebar. The bottom end of the releasing column 205 is fixedly connected to a turntable 204, thereby driving the turntable 204 to rotate synchronously. The turntable 204 is used to support the rebar. By actively controlling the rotation of the releasing columns 205 around the main shaft 203 through the drive assembly 202, the release speed of the rebar can be controlled, avoiding the release speed due to weight. The excessively fast wire feeding caused by force or inertia reduces manual intervention and improves efficiency; the wire feeding process is stabilized by the drive component 202, which can reduce length or displacement deviation caused by uneven wire feeding speed and ensure that the reinforcement arrangement meets the design requirements; by setting multiple wire feeding frames 2 and paired first guide wire mechanism 3 on the frame 1, the first guide wire mechanism 3 can guide the reinforcement on the wire feeding column 205 to the feeding position of the next process (such as straightening machine or bending machine); multiple wire feeding frames 2 can be used for reinforcements of different diameters and strengths, which is highly versatile and allows for synchronous feeding, thus improving feeding efficiency.

[0061] In some embodiments, the wire feeding frame 2 further includes a bushing 206, which is fixedly disposed on the wire feeding base 201. At least two wire feeding bearings 207 are concentrically installed inside the bushing 206 along the axial direction of the bushing 206. The main shaft 203 passes through the bushing 206 and is rotatably connected to the wire feeding bearings 207.

[0062] like Figure 3 and Figure 4 Two wire-feeding bearings 207 are concentrically mounted inside a bushing 206. The main shaft 203 passes through the two wire-feeding bearings 207 and is concentrically mounted inside the bushing 206 to ensure the axial stability of the main shaft 203. The bottom end of the main shaft 203 is connected to a drive assembly 202 below the wire-feeding base 201. The drive assembly 202 includes a motor and a reducer. The top end of the main shaft 203 passes through the bushing 206 and is fixedly connected to a fixing plate 209. A connecting plate 208 is fixedly connected to the fixing plate 209. There are three sets of connecting plates 208, each set of which is fixedly connected to a wire-feeding column 205. When the drive assembly 202 drives the main shaft 203 to rotate, the main shaft 203 drives the connecting plate 208 to rotate via the fixing plate 209. The connecting plate 208 drives the wire-feeding column 205 to rotate, and the wire-feeding column 205 is fixed to the turntable 204, causing the turntable 204 to rotate accordingly.

[0063] The wire feeding base 201 is fixed to the frame 1. Multiple wire feeding frames 2 can each have their own wire feeding base 201 for individual fixing to the frame 1. When multiple wire feeding frames 2 are arranged sequentially along a first direction, they can share the wire feeding base 201. In some embodiments, such as... Figure 3 At least two sets of adjusting seats are evenly arranged around the axis of the turntable 204. Each set of adjusting seats includes three support rods 210, and the three support rods 210 of the two sets of adjusting seats are arranged alternately. The three wire-feeding columns 205 can be selectively fixed on the three support rods 210 in any set of adjusting seats. Each support rod 210 has an adjusting hole 211 along the radial direction of the turntable 204. The wire-feeding columns 205 can be selectively installed on any one of the adjusting holes 211, which can realize the adjustment of the outer diameter of the three wire-feeding columns 205. The length of the connecting plate 208 in the radial direction is adjustable to adapt to the radial position of the wire-feeding columns 205.

[0064] In some embodiments, the first conductor mechanism 3 includes a first column 301, a rotating frame 302, a wire guide wheel 306, a shock-absorbing pad 307, and an elastic component. The first column 301 is fixedly mounted on the wire-laying base 201. The rotating frame 302 is located on one side of the first column 301 and faces the wire-laying frame 2. The rotating frame 302 is provided with a wire-laying mounting block 303, and the wire-laying mounting block 303 is provided with a mounting plate 304 and a limiting plate 305. The wire guide wheel 306 is rotatably mounted on the mounting plate 304, and one end of the reinforcing bar can be wound around the wire guide wheel 306. The shock-absorbing pad 307 is located between the wire-laying mounting block 303 and the rotating frame 302. The elastic component is located between the first column 301 and the rotating frame 302 to elastically mount the rotating frame 302 on the first column 301.

[0065] like Figure 5 and Figure 6 As shown, the first copper sleeve 3021 is concentrically mounted on the rotary frame 302; the wire guide mounting block 303 is mounted on the top of the rotary frame 302 and concentrically mounted with the first copper sleeve 3021, and partitions 3031 are provided on both sides of the wire guide mounting block 303 to isolate the wire guide mounting block 303 and the inner sidewall of the rotary frame 302, and to improve the coaxiality of the wire guide mounting block 303 and the rotary frame 302. The second copper sleeve 3032 is concentrically installed in the mounting hole of the wire guide mounting block 303; one end of the mounting plate 304 is concentrically installed and inserted into the second copper sleeve 3032, and the other end of the mounting plate 304 is provided with a mounting groove for rotatably installing the follower roller 312 and the wire guide wheel 306; the limiting plate 305 is installed on the upper side of the wire guide mounting block 303, and the top insertion rod 3041 of the mounting plate 304 can be inserted into the limiting hole 3051 on the limiting plate 305, thereby controlling the circumferential rotation of the mounting plate 304; the follower roller 312 and the wire guide wheel 306 are spaced apart and rotatably installed on the mounting plate 304, and the reinforcing bar can pass through the channel between the rim groove of the follower roller 312 and the wire guide wheel 306. Figure 6 The two ends of the follower shaft are fixedly connected to the two opposite side walls of the mounting groove by bolts and nuts. Two second bearings 3121 are concentrically mounted on the follower shaft, and the follower roller 312 is sleeved on the two second bearings 3121 to achieve the rotatable installation of the follower roller 312 and the follower shaft. When the reinforcing bar moves, the follower roller 312 can roll accordingly. The two ends of the wire guide wheel shaft are fixed to the two side walls of the mounting groove by bolts and nuts. Two first bearings 3061 are concentrically mounted on the wire guide wheel shaft for rotatably installing the wire guide wheel 306. The wire guide wheel 306 and the follower roller 312 form a channel for the reinforcing bar to pass through. The wire guide wheel shaft and the follower shaft are arranged parallel to each other.

[0066] A shock-absorbing base plate 3071 is provided below the cable mounting block 303. One end of the shock-absorbing base plate 3071 is fixedly connected to the lower surface of the cable mounting block 303, and the other end of the shock-absorbing base plate 3071 is bent downward to form an L-shape. A shock-absorbing pad 307 is installed on the side wall of the downwardly bent part of the shock-absorbing base plate 3071 facing the first column 301. The shock-absorbing pad 307 is in elastic contact with the rotating frame 302 to achieve the shock absorption effect on the cable mounting block 303.

[0067] In some embodiments, the elastic component includes a spring mounting base 308, a mounting cover 311, and a spring 310. The spring mounting base 308 is installed inside a fixing block 309, which is fixed to the rotating frame 302. One end of the mounting cover 311 is fixed to the rotating frame 302, and the other end is fixed to the first column 301. One end of the spring 310 is installed on the spring mounting base 308, and the other end of the spring 310 is connected to the mounting cover 311.

[0068] Combination Figure 5 and Figure 6 The spring mounting base 308 is concentrically mounted inside the fixing block 309, and the fixing block 309 is concentrically mounted inside the rotary frame 302 and fixedly connected to the rotary frame 302; one end of the spring 310 is mounted on the spring mounting base 308; the mounting cover 311 is U-shaped and fastens the spring mounting base 308 and the spring 310, and the two free ends of the mounting cover 311 are respectively fixedly connected to the rotary frame 302 and the first column 301, as shown. Figure 6 The upper free end of the mounting cover 311 is fixedly connected to the first column 301, and the lower free end is fixedly connected to the rotating frame 302. The mounting cover 311 is fitted with two springs 310 and is installed concentrically with the two springs 310. During the movement of the rebar laying line, the force acting on the line-passing mounting block 302 is buffered by the anti-vibration pad 307, thereby reducing the vibration of the rotating frame 302. At the same time, the vibration of the rotating frame 302 is buffered and damped by the compression springs 310 of the mounting cover 311, reducing the vibration transmission of the rotating frame 302 to the first column 301.

[0069] In some embodiments, among the plurality of first conductor mechanisms 3 along the first direction, except for the first first conductor mechanism 3, the remaining first conductor mechanisms 3 are sequentially provided with wear-resistant joint components 4 with an increasing number of wear-resistant joints, and the steel bars on the plurality of first conductor mechanisms 3 are sequentially threaded through the plurality of coaxial wear-resistant joints.

[0070] like Figure 2 As shown, among the four first guide wire mechanisms 3 arranged along the first direction on the frame 1, except for the first one, the other three first guide wire mechanisms 3 are respectively provided with wear-resistant slot components 4. The wear-resistant slot components 4 have wear-resistant slots, and the reinforcing bars can be passed through the wear-resistant slots to realize long-distance wire feeding and conveying. They have the function of straightening and correcting the reinforcing bars, and are convenient for diverting or dispersing multiple reinforcing bars of different specifications.

[0071] In some embodiments, the wear-resistant joint assembly 4 includes a wear-resistant joint mounting base 401, an upper pressure block 402, and a buckle 405. One end of the wear-resistant joint mounting base 401 is fixedly connected to the first column 301, and the other end of the wear-resistant joint mounting base 401 is provided with a first half-wear-resistant joint. The upper pressure block 402 is provided with a second half-wear-resistant joint. The upper pressure block 402 is rotatably mounted on the wear-resistant joint mounting base 401. The openings of the first half-wear-resistant joint and the second half-wear-resistant joint are opposite to each other and can be interlocked to form a first wear-resistant joint 404. The reinforcing bar can be inserted into the first wear-resistant joint 404. The two ends of the buckle 405 are respectively connected to the upper pressure block 402 and the wear-resistant joint mounting base 401 to lock the first wear-resistant joint 404.

[0072] like Figures 7-9 The three wear-resistant joint components 4 shown are respectively disposed on the three first guide wire mechanisms 3, and the number of wear-resistant joints on the wear-resistant joint components 4 increases sequentially along the positive X direction. In some embodiments, the wear-resistant joint mounting base 401 is also provided with a second wear-resistant joint 406. Along the first direction, the number of second wear-resistant joints 406 on the subsequent wear-resistant joint component 4 is one more than the number of second wear-resistant joints 406 on the previous wear-resistant joint component 4. The second wear-resistant joints 406 on the subsequent wear-resistant joint component 4 are coaxially arranged with the first wear-resistant joints 404 or the second wear-resistant joints 406 on the previous wear-resistant joint component 4. The reinforcing bar passes through the multiple coaxially arranged first wear-resistant joints 404 and second wear-resistant joints 406. The buckle 405 can be an elastic buckle 405. One end of the buckle 405 is fixed on the wear-resistant joint mounting base 401, and the other end can be elastically hooked to the upper pressure block 402 to achieve locking.

Figure 7 The wear-resistant assembly 4 shown has a first wear-resistant opening 404. The second-specification reinforcing bar is directly led out through the guide wheel 306 of the second first conductor mechanism 3. Simultaneously, the first-specification reinforcing bar passes through the first wear-resistant opening 404 of the wear-resistant assembly 4 on the second first conductor mechanism 3 to continue extending forward. A third first conductor mechanism 3 is provided with… Figure 8 The wear-resistant joint assembly 4 shown has a first wear-resistant joint 404 and a second wear-resistant joint 406. The second wear-resistant joint 406 is coaxial with the first wear-resistant joint 404 on the wear-resistant joint assembly 4 on the second first conductor mechanism 3. A first-specification steel bar is inserted through the coaxial second wear-resistant joint 406 and the first wear-resistant joint 404 (i.e., Figure 7 The first wear-resistant joint of 404 and Figure 8The second wear-resistant joint 406), the second specification steel bar is threaded through the first wear-resistant joint assembly 4 on the third first conductor mechanism 3, the first wear-resistant joint 404 ( Figure 8 The first wear-resistant opening 404 in the middle, the third specification steel bar is led out from the wire guide wheel 306 on the third first conductor mechanism 3; the fourth first conductor mechanism 3 is equipped with Figure 9 The wear-resistant joint assembly 4 shown has a first wear-resistant joint 404 and two second wear-resistant joints 406.

The left box plate 5023 and the box mounting plate 5025 are respectively located on both sides of the second column 501 and are fixedly connected by bolts and nuts to realize the installation of the conductor box 502 and the second column 501. A diagonal brace 5011 is provided between the second column 501 and the frame 1 to increase the connection strength of the second column 501. Inside the wire guide box 502, third bearings 5031 are installed at both ends of the long guide roller 503; long guide shafts 5032 are concentrically installed in the long guide roller 503 and the third bearings 5031 at both ends; first spacers 5033 are fixedly installed on the upper box plate 5021 and the lower box plate 5022 respectively. The long guide shafts 5032 at both ends of the long guide roller 503 pass through the first spacers 5033 on the upper box plate 5021 and the lower box plate 5022 respectively to rotatably connect them. The first spacers 5033 are located at the long guide roller 503 and the upper box plate 5021, and the long guide roller 503 and the lower box plate 5022 to isolate them. The long guide roller 503 can rotate freely. The two long guide rollers 503 are located on the left and right sides of the wire guide box 502 and are parallel to each other.

[0076] For example Figure 12There are three mounting panels 505. One mounting panel 505 is fixedly connected to the right housing plate 5024. The mounting panel 505 has a through hole. A fifth bearing 507 is installed at both ends of the shaft hole of each guide wheel 506. The guide wheel shaft 508 passes through the fifth bearing 507, the shaft hole of the guide wheel 506, and the through hole on the mounting panel 505 and is fixedly connected. The outermost mounting panel 505 has a limiting baffle 509, which is fixed to the mounting panel 505 and connected to the guide wheel shaft 508. The limiting baffle 509 is used to axially fix the guide wheel shaft 508. A second spacer 510 is concentrically installed on both ends of each guide wheel 506 on the guide wheel shaft 508. The second spacer 510 is located between the guide wheel 506 and the mounting panel 505 to isolate them. Connecting screw and nut assemblies are passed through the upper and lower ends of the three mounting panels 505 to further secure the connection between the three mounting panels 505. In this embodiment, three guide wheels 506 are installed between any two adjacent mounting panels 505, and reinforcing bars can be threaded through the rim grooves of two adjacent guide wheels 506. Figure 11 The six guide rollers 506 form four small-hole channels for rebar threading, suitable for small-sized rebars; the two long guide rollers 503 and the two short guide rollers 504 form large-hole channels for rebar threading within the conductor box 502, suitable for large-sized rebars.

[0077] In some embodiments, at least two second conductor mechanisms 5 are provided, and the at least two second conductor mechanisms 5 are spaced apart along a first direction to divert multiple reinforcing bars from the first conductor mechanism 3.

[0078] like Figure 2 As shown, two second guide wire mechanisms 5 are arranged on the frame 1 along the first direction. The two second guide wire mechanisms 5 can have the same structure, or different specifications of second guide wire mechanisms 5 can be set according to the requirements of the rebar diversion. For example, the size of the guide wheel 506 can be increased or decreased to adapt to different specifications of rebar; the number of guide wheels 506 can be increased or decreased to adapt to the diversion of more rebars on more wire feeding frames 2; the position of the second guide wire mechanism 5 on the frame 1 can be adjusted to adapt to the rebar feeding position of the next process, etc.

[0079] The rebar braking and setting-out device and method provided by this utility model include the following steps:

[0080] S1, various steel bars of different specifications (such as different diameter specifications) are wound on multiple wire feeding frames 2, and one end of each steel bar is threaded through a first conductor mechanism 3 and led out;

[0081] Through multiple first guide wire mechanisms 3 and second guide wire mechanisms 5, the steel bars are sequentially inserted, diverted, and led out to the feeding end of the next process.

[0082] By setting the wear-resistant joint component 4, the steel bars on multiple wire feeding frames 2 can be better distributed and fed onto the wire.

[0083] S2, determine the required specifications of the steel bars, start the drive component 202 on the corresponding wire feeding frame 2, the drive component 202 drives the main shaft 203 to rotate, the main shaft 203 drives the wire feeding column 205 and the turntable 204 to rotate, and the steel bars are fed out at the set speed;

[0084] By controlling the power of the motor and reducer in the drive assembly 202, the rotational speed of the turntable 204 and the wire-laying column 205 is controlled, thereby controlling the rebar release speed.

[0085] S3, after the line laying is completed, the drive component 202 is turned off, the turntable 204 and the line laying column 205 stop rotating, and the rebar laying stops.

[0086] The drive component 202 can stably control the rebar laying process, reduce length or displacement deviations caused by uneven speed, and ensure that the rebar arrangement meets the design requirements. Multiple sets of guide wire mechanisms (including the first guide wire mechanism 3 and the second guide wire mechanism 5) work together to smoothly disperse the rebar into the main machine (including the straightening machine / bending machine). It is applicable to rebars of different diameters and strengths, and has strong versatility.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
