[0116] When the steel bar passes through the wire passing channel, the wire passing wheel 136 and the follower roller 139 rotate, and since the wire passing mounting block 133 is rotatably arranged on the rotating frame 132 and the wire passing mounting plate 134 is rotatably arranged on the wire passing mounting block 133, the force applied by the steel bar on the follower roller 139 and the wire passing wheel 136 can be reduced, thereby prolonging the service life of the follower roller 139 and the wire passing wheel 136.

[0129] Reference Figure 1 As shown, the wire laying device 1 further comprises a wire laying fence net surrounding the wire rack 12 to avoid irrelevant personnel from entering by mistake.

[0130] Reference Figures 13-32 As shown, the straightening device 2 further comprises a traction mechanism 22 and a conveying mechanism 24, the conveying mechanism 24 comprises a moving frame 244 and a conveying driving member 241, the moving frame 244 is movably arranged on the straightening rack 21 in the second direction, and the conveying driving member 241 is used to drive the moving frame 244 to move, and the traction mechanism 22 and the straightening mechanism 23 are arranged on the moving frame 244 to move relative to the straightening rack 21 in the second direction under the driving of the conveying driving member 241. Specifically, any straightening roller 231 is rotatably arranged on the moving frame 244 through a straightening roller seat 233, and any straightening roller 231 extends in the first direction. The traction mechanism 22 comprises a plurality of traction assemblies 221 corresponding to each straightening roller 231, and each traction assembly 221 is used to traction reinforcing steel bars of different diameters into the corresponding straightening roller 231.

[0131] Reference Figures 17-18As shown, the traction assembly 221 comprises a traction driven wheel 2211 and a traction driving wheel 2212, a clamping space for clamping the reinforcing steel bars is formed between the traction driven wheel 2211 and the traction driving wheel 2212, and a traction driving member 2218 is connected to the traction driving wheel 2212 to drive the traction driving wheel 2212 to rotate, thereby driving the reinforcing steel bars to move towards the straightening roller 231.

[0132] In some embodiments, in order to smoothly enter the clamping space, the traction assembly 221 further comprises a first adjusting driving member 2213 for driving the traction driven wheel 2211 to move towards or away from the traction driving wheel 2212 to loosen or clamp the reinforcing steel bars of different diameters.

[0133] Specifically, any traction assembly 221 comprises at least two traction driven wheels 2211 and traction driving wheels 2212 corresponding to the traction driven wheels 2211, and the traction driven wheels 2211 are arranged in a spaced apart manner along a first direction. In order to realize the synchronous movement of the traction driven wheels 2211 relative to the traction driving wheels 2212, the traction driven wheels 2211 are connected by a seesaw frame 2214, and the traction driven wheels 2211 are rotatably connected to the seesaw frame 2214 by seesaw shafts, and the first adjusting driving member 2213 is connected to the seesaw frame 2214.

[0134] In order to improve the clamping force of the traction driven wheels 2211 and the traction driving wheels 2212 on the reinforcing steel bars and prevent the reinforcing steel bars from slipping relative to the traction driven wheels 2211 and the traction driving wheels 2212, the traction assembly 221 further comprises a pressing arm 2215, a seesaw connecting frame 2216 and a connecting rod arm 2217. The pressing arm 2215 is rotatably arranged on the moving frame 244 by a pressing pin shaft, the first end of the pressing arm 2215 is connected to the first end of the seesaw connecting frame 2216, the second end of the pressing arm 2215 is connected to the first adjusting driving member 2213, one end of the connecting rod arm 2217 is coaxially rotatably connected to the seesaw frame 2214 at the second end of the seesaw connecting frame 2216, and the other end of the connecting rod arm 2217 is rotatably connected to the moving frame 244. A four-bar linkage structure is formed between the connecting rod arm 2217, the moving frame 244, the seesaw connecting frame 2216 and the pressing arm 2215. Under the action of the first adjusting driving member 2213, the traction driven wheels 2211 move towards the traction driving wheels 2212 and clamp the reinforcing steel bars, and the clamping force is large. Moreover, the distance between the pressing pin shaft and the first end of the pressing arm 2215 is smaller than the distance between the pressing pin shaft and the second end of the pressing arm 2215, so that the pressing arm 2215 acts as a force-saving lever, and the clamping force exerted by the first adjusting driving member 2213 on the reinforcing steel bars through the traction driven wheels 2211 is greater.

[0135] In addition, the outer circumferential surface of the traction driven wheel 2211 and / or the traction driving wheel 2212 is also provided with anti-skid lines to further prevent the steel bar from slipping. Exemplarily, the traction driven wheel 2211 and / or the traction driving wheel 2212 adopts a V-shaped wheel to prevent the steel bar from being axially displaced relative to the traction driven wheel 2211 and the traction driving wheel 2212, and the first adjusting driving member 2213 adopts a pneumatic cylinder.

[0136] Reference Figure 19 As shown, in order to reduce the use cost of the straightening device 2, the traction assemblies 221 share a traction driving member 2218. Based on this, the traction mechanism 22 further comprises a transmission assembly 222 connected between the traction driving member 2218 and the traction driving wheels 2212 to realize the synchronous rotation of the traction driving wheels 2212.

[0137] Specifically, the transmission assembly 222 comprises traction main shafts 2221 extending along the second direction, the traction driving wheels 2212 of each traction assembly 221 are spaced and sleeved on the traction main shafts 2221 and rotate with the traction main shafts 2221, and the traction driving member 2218 is connected to the traction main shafts 2221 to drive the traction main shafts 2221 to rotate. Based on the premise that the traction assembly 221 comprises two traction driving wheels 2212, two traction main shafts 2221 are spaced apart along the first direction, and the two traction driving wheels 2212 of the traction assembly 221 are respectively sleeved on the two traction main shafts 2221. At this time, the transmission assembly 222 further comprises traction pulleys 2222 and a traction belt, the traction driving member 2218 adopts a motor, and the output shaft of the traction driving member 2218 and the traction main shafts 2221 are both provided with traction pulleys 2222 and are transmissionally connected through the traction belt.

[0138] More specifically, in order to prevent the traction driving wheels 2212 from moving axially relative to the traction main shafts 2221, the transmission assembly 222 further comprises spacers 2224 and gland nuts 2223, the gland nuts 2223 are arranged on both sides of the traction main shafts 2221, and the spacers 2224 are arranged between adjacent traction driving wheels 2212, between the traction driving wheels 2212 and the traction pulleys 2222, and between the traction driving wheels 2212 and the gland nuts 2223.

[0139] In some embodiments, the traction mechanism 22 further comprises first limiting assemblies 223, and a plurality of first limiting assemblies 223 are correspondingly arranged upstream of each traction assembly 221 to limit the steel bar to prevent the steel bar from jumping during straightening.

[0140] Reference Figures 22-23As shown, the first limiting component 223 includes a limiting drive component 2231, a first locking block 2232, a second locking block 2233, and a fixing base 2234. The fixing base 2234 has a mounting groove 22341. The first locking block 2232 is fixed within the mounting groove 22341. The second locking block 2233 is connected to the limiting drive component 2231 and moves along a third direction under the action of the limiting drive component 2231. Figure 1 The steel bar is moved closer to or further away from the first clamping block 2232 in the Z direction, thereby cooperating with the first clamping block 2232 to clamp the steel bar and realize the limitation of the steel bar along the second direction and the third direction. The third direction is perpendicular to the first direction and the second direction.

[0141] More specifically, the limiting drive component 2231 also employs a cylinder. To prevent the first limiting component 223 from locking the reinforcing bar, the first limiting component 223 further includes a second elastic element 2235. The second elastic element 2235 is connected to the second locking block 2233 and the fixing seat 2234, and tends to keep the second locking block 2233 away from the first locking block 2232. Exemplarily, the second elastic element 2235 is a spring, with one end connected to the second locking block 2233 and the other end passing through the fixing seat 2234 and connected to the spring base 2236 fixed on the fixing seat 2234.

[0142] Continue to refer to Figures 22-23 As shown, the first limiting component 223 also includes a guide rod 2238. One end of the guide rod 2238 is connected to the limiting drive component 2231, and the other end passes through the first locking block 2232 and connects to the second locking block 2233. Furthermore, two guide rods 2238 are spaced apart along the second direction, and the reinforcing bar is limited between the two guide rods 2238, the first locking block 2232, and the second locking block 2233. It can be understood that, in addition to limiting the reinforcing bar, the guide rods 2238 also guide the movement direction of the second locking block 2233. Furthermore, to facilitate timely replacement of the first locking block 2232 and the second locking block 2233, the mounting groove 22341 extends through the fixing seat 2234 along the first direction. Simultaneously, each of the opposite sidewalls of the mounting groove 22341 has a recessed groove 22342 extending through the sidewall of the mounting groove 22341 along the first direction. The opposite ends of the first locking block 2232 are embedded in the recessed groove 22342. When the first locking block 2232 needs to be replaced, it only needs to be moved along the first direction. Moreover, the first limiting component 223 also includes a locking block mounting seat 2237, which has a fixing groove. The second locking block 2233 is fixed to the locking block mounting seat 2237 using a method not limited to bolt connection. The guide rod 2238 connects to the second locking block 2233 by connecting to the locking block mounting seat 2237.

[0143] refer to Figures 20-21As shown, the traction mechanism 22 further comprises a second limiting assembly 224 to further limit the reinforcing steel. The second limiting assembly 224 comprises at least two groups of wire guide wheels, the wire guide wheels in the groups are spaced apart along the first direction, and any wire guide wheel group comprises two second wire guide wheels 2241 spaced apart along the second direction, the reinforcing steel can pass between the two second wire guide wheels 2241. It is worth emphasizing that the first limiting assembly 223 is arranged between the two groups of wire guide wheels, and then the first limiting assembly 223 and the second limiting assembly 224 are arranged in multiple groups of limiting in the first direction, i.e., the transmission direction of the reinforcing steel, and the limiting effect is better.

[0144] The straightening roller 231 comprises a roller body 2311 and a straightening die 2312 arranged in the roller body 2311 along the length direction of the roller body 2311, i.e., along the first direction, and the two ends of the roller body 2311 along the first direction are open, and each end of the roller body 2311 along the first direction is rotatably connected to the straightening roller seat 233 through an axle head 2315, specifically, one end of the axle head 2315 is rotatably connected to the straightening roller seat 233, and the other end is inserted into the roller body 2311 from the opening of the roller body 2311 and is fixedly connected with the roller body 2311, and an axle hole 23151 for the reinforcing steel to pass through is arranged in the axle head 2315, and the two ends of the axle hole 23151 are tapered from the end to the center to reduce the difficulty of inserting the reinforcing steel.

[0145] Specifically, the roller body 2311 comprises four panels which are combined to form a closed structure, and the four panels are bolted to facilitate later maintenance and replacement of the straightening die 2312. In order to reduce the weight of the first straightening roller 231a and thus reduce the load of the straightening driving member 232, and in order to observe the position of the straightening die 2312 in the first roller body 2311, a plurality of lightening holes corresponding to the straightening die 2312 are formed on the roller body 2311.

[0146] Based on reinforcing steel of different diameters, the structure of the straightening die 2312 used is also different. In some embodiments, the straightening roller 231 is divided into a first straightening roller 231a and a second straightening roller 231b, wherein the first straightening roller 231a is used to straighten reinforcing steel with a relatively small diameter, for example, the first straightening roller 231a is used to straighten reinforcing steel with a diameter of 6-16 mm, and the second straightening roller 231b is used to straighten reinforcing steel with a relatively large diameter, for example, the second straightening roller 231b is used to straighten reinforcing steel with a diameter of 16-25 mm.

[0147] Reference Figure 24 and Figure 25As shown, the straightening die 2312 of the first straightening roller 231a adopts a nozzle group, and the nozzle group is provided with 5 groups exemplarily. The nozzle group further comprises a nozzle 23121, a guide nozzle 23122 and a straightening clamp block 23123. The nozzle 23121 is fixedly arranged in the roller body 2311, and the nozzle 23121 is provided with a mounting hole penetrating the nozzle 23121 along the length direction of the roller body 2311. The straightening clamp block 23123 is mounted in the mounting hole, and the straightening clamp block 23123 is provided with a straightening hole penetrating the straightening clamp block 23123 along the length direction of the roller body 2311. Adjacent straightening holes are arranged in a staggered manner in a direction perpendicular to the first direction. The plurality of guide nozzles 23122 are connected to the upstream side of the nozzle 23121 in a manner not limited to bolt connection. The inner wall surface of the guide nozzle 23122 is tapered, that is, the inner diameter gradually increases from one side close to the nozzle 23121 to the other side, so as to guide the steel bar into the straightening hole. The straightening clamp block 23123 can extrude the steel bar passing through the straightening clamp block 23123, and cooperate with the rotation of the roller body 2311 and the feeding speed of the steel bar, so that the steel bar is forced to be straightened. The straightening clamp block 23123 is assembled in the nozzle 23121 by means of hot mounting process, so as to make the straightening clamp block 23123 and the nozzle 23121 in interference fit, thereby improving the stable connection of the straightening clamp block 23123 and the nozzle 23121.

[0148] Specifically, the position of the nozzle group in the roller body 2311 is adjustable, so as to adjust the tension of each straightening clamp block 23123 on the steel bar. With continuous reference to Figure 24 As shown, the nozzle group is slidingly arranged in the roller body 2311 along the width direction of the roller body 2311. The first straightening roller 231a further comprises an adjusting nut 2314 and an adjusting rod 2313. The adjusting rod 2313 penetrates the roller body 2311 and is connected with the nozzle group. The adjusting nut 2314 is located outside the roller body 2311 and abuts against the roller body 2311. The adjusting nut 2314 is sleeved on the adjusting rod 2313 and is threadedly connected with the adjusting rod 2313. By suspending the adjusting nut 2314, the adjusting rod 2313 moves relative to the roller body 2311 along the width direction of the roller body 2311, so as to adjust the position of the nozzle group in the roller body 2311.

[0149] The steel bar with a larger diameter needs to release less stress than the steel bar with a smaller diameter during the straightening process. In order to reduce the friction with the steel bar during the straightening process, with reference to Figures 26-28As shown, the straightening die 2312 of the second straightening roller 231b for straightening the larger diameter steel bars adopts a straightening roller set, which in turn comprises a straightening roller seat 23125 and straightening rollers 23124. The straightening roller seat 23125 is fixed in the roller body 2311 and is arranged in a substantially U-shaped manner. The straightening rollers 23124 are rotatably arranged in the straightening roller seat 23125 through straightening roller shafts 23126 and cooperate with the straightening roller seat 23125 to form straightening holes. The straightening roller shafts 23126 are arranged at an angle to the length direction of the roller body 2311, i.e., the first direction, so as to straighten the steel bars in cooperation with the straightening roller seat 23125 and also provide an axial conveying force to the steel bars, so that the steel bars are conveyed in the axial direction during the straightening process.

[0150] Specifically, the straightening rollers 23124 also adopt V-shaped rollers, and the surface of the straightening roller seat 23125 facing the straightening rollers 23124 is arranged as a concave circular surface to increase the contact area with the steel bars, so as to better apply force to the steel bars and achieve better straightening effect. Exemplarily, the straightening roller set is provided with five groups, of which two groups arranged on both sides of the roller body 2311 are coaxial or approximately coaxial with the shaft hole 23151, and the two groups mainly serve as a guide. The other three groups are arranged in a staggered manner perpendicular to the length direction of the roller body 2311 and mainly serve as a straightening function.

[0151] Similarly, the position of the straightening roller set in the second roller body 2311 is adjustable, and the adjustment manner is the same as that of the nozzle set, i.e., the second straightening roller 231b also comprises an adjusting nut 2314 and an adjusting rod 2313 connected to the straightening roller set, which will not be described herein again.

[0152] Specifically, when the angle between the straightening roller shafts 23126 and the length direction of the roller body 2311 is 30-40°, the straightening effect and conveying capacity are both good. When the angle between the roller shafts and the length direction of the roller body 2311 is 36°, the straightening effect and conveying capacity are best.

[0153] In addition, in order to avoid mutual interference, the straightening driving members 232 are arranged in one-to-one correspondence with the straightening rollers 231. Exemplarily, the straightening driving members 232 also adopt motors, which are drivingly connected to the straightening rollers 231 through a belt transmission structure.

[0154] Reference Figure 15As shown, the conveying mechanism 24 comprises a conveying driving member 241, a driving sprocket 242, a driven sprocket 243 and a chain, the conveying driving member 241 is connected to the driving sprocket 242 to drive the chain to move the driving sprocket 242 and the driven sprocket 243, and the moving frame 244 is connected to the chain to move when the chain moves. Specifically, in order to improve the stability of the movement of the moving frame 244, the moving frame 244 is slidingly arranged on the straightening frame 21 on opposite sides in the first direction. At the same time, in order to improve the synchronization of the movement of the opposite sides of the moving frame 244, the straightening frame 21 is provided with a chain, a driving sprocket 242 and a driven sprocket 243 on opposite sides, and the opposite sides of the moving frame 244 are connected to the chain. At the same time, in order to save power, the driving sprockets 242 on the left and right sides of the straightening frame 21 are connected to the same conveying driving member 241 through a sprocket shaft. Exemplarily, the conveying driving member 241 is a servo motor used in cooperation with a speed reducer.

[0155] More specifically, the opposite sides of the straightening frame 21 are provided with sliding grooves, and the moving frame 244 is slidingly arranged in the sliding grooves. Nylon blocks are also arranged in the sliding grooves in the moving direction of the moving frame 244, which serve to support and prevent wear. Compared with a nylon strip arranged integrally, the nylon blocks are less likely to deform and have better guiding effect.

[0156] In some embodiments, the wire feeding mechanism 25 is arranged upstream of the traction mechanism 22, that is, the wire feeding mechanism 25, the traction mechanism 22 and the straightening mechanism 23 are arranged in sequence on the straightening frame 21.

[0157] Reference Figure 29 As shown, the wire feeding mechanism 25 comprises a wire feeding seat 251, a wire feeding driving wheel 252, a wire feeding driven wheel 253, a wire feeding driving member 254 and a second adjusting driving member 255, the wire feeding driving wheel 252 and the wire feeding driven wheel 253 are arranged on the wire feeding seat 251 in the second direction, the wire feeding driving member 254 is connected to the wire feeding driving wheel 252 to drive the wire feeding driving wheel 252 to rotate, and the wire feeding driven wheel 253 can move towards or away from the wire feeding driving wheel 252 under the action of the second adjusting driving member 255 to clamp the reinforcing steel bars and cooperate with the wire feeding driving wheel 252 to convey the reinforcing steel bars. Exemplarily, the wire feeding driving member 254 is an electric motor.

[0158] Specifically, the incoming wire driving wheel 252 and the incoming wire driven wheel 253 are both spaced apart in the first direction, and two are arranged to improve the stability of the steel bar conveying. On this basis, in order to realize the synchronous movement of the two incoming wire driven wheels 253, the incoming wire driven wheel 253 is slidingly arranged in the guide groove opened in the incoming wire seat 251 through the feeding slider 256, the pushing shaft 257 is arranged on the feeding slider 256, and the second adjusting drive 255 adopts a pneumatic cylinder. The incoming wire mechanism 25 further comprises a downward rocker 258, and the two ends of the second adjusting drive 255 are both connected with the downward rocker 258. The downward rocker 258 is rotationally arranged on the incoming wire seat 251, and the end of the downward rocker 258 away from the second adjusting drive 255 abuts against the pushing shaft 257. When the second adjusting drive 255 is retracted, the downward rocker 258 rotates, and the end of the downward rocker 258 away from the second adjusting drive 255 pushes the pushing shaft 257, so that the incoming wire driven wheel 253 approaches the incoming wire driving wheel 252, and then clamps the steel bar and cooperates with the incoming wire driving wheel 252 to convey the steel bar.

[0159] More specifically, the incoming wire mechanism 25 further comprises a third elastic element 259, which is arranged between the feeding slider 256 and the groove bottom wall of the guide groove, so as to keep the feeding slider 256 away from the incoming wire driving wheel 252, so as to avoid the incoming wire driving wheel 252 and the incoming wire driven wheel 253 from clamping the steel bar, thereby affecting the steel bar conveying.

[0160] It can be understood that the incoming wire mechanism 25 is only used to guide the steel bar to the traction mechanism 22 at the initial stage, and after the steel bar contacts the traction mechanism 22, the incoming wire mechanism 25 does not need to perform the function of conveying the steel bar. Based on this, as shown in Figure 30 The incoming wire mechanism 25 further comprises an avoidance drive 2510, the incoming wire seat 251 comprises an incoming wire frame 2511 and an avoidance plate 2512, the incoming wire frame 2511 is fixed on the straightening frame 21, the avoidance plate 2512 is movably arranged on the incoming wire frame 2511 in the third direction, and the avoidance drive 2510 is used to drive the avoidance plate 2512 to move. The incoming wire driving wheel 252 and the incoming wire driven wheel 253 are both arranged on the avoidance plate 2512. After the steel bar contacts the traction mechanism 22, the avoidance plate 2512 drives the incoming wire driving wheel 252 and the incoming wire driven wheel 253 to retreat, so as to avoid the steel bar, thereby reducing the resistance of the steel bar movement.

[0161] Specifically, the avoidance plate 2512 is located in the incoming wire frame 2511, and the two sides of the avoidance plate 2512 arranged opposite in the first direction are both slidingly arranged on the incoming wire frame 2511, and the avoidance drive 2510 also adopts a pneumatic cylinder.

[0162] Referring to Figure 29 and Figure 30As shown, the threading mechanism 25 further comprises longitudinal threading rollers 2520, transverse threading rollers 2530 and a threading fixing plate 2540, the longitudinal threading rollers 2520 and the transverse threading rollers 2530 are vertically arranged, two longitudinal threading rollers 2520 are parallelly and spacedly arranged on the threading fixing plate 2540 and are rotatably connected to the threading fixing plate 2540, and two transverse threading rollers 2530 are parallelly and spacedly arranged on the threading fixing plate 2540 and are rotatably connected to the threading fixing plate 2540. The reinforcing steel bar can pass between the two longitudinal threading rollers 2520 and the two transverse threading rollers 2530 to achieve preliminary constraint.

[0163] The straightening device 2 further comprises a winch 26 arranged between the threading mechanism 25 and the traction mechanism 22 to introduce the reinforcing steel bar into the threading mechanism 25. When the straightening device 2 works, the end of the reinforcing steel bar is connected with the wire rope on the winch 26, so as to introduce the reinforcing steel bar between the threading driving roller 252 and the threading driven roller 253, which saves the time for manually introducing the reinforcing steel bar into the threading mechanism 25 and further improves the efficiency of the reinforcing steel bar straightening.

[0164] Reference Figure 13 As shown, the straightening device 2 further comprises a guide roller 27 arranged between the threading mechanism 25 and the traction mechanism 22 and extending along the second direction, which is used for guiding the reinforcing steel bar to smoothly enter the traction mechanism 22.

[0165] In some embodiments, the straightening device 2 further comprises a counting mechanism 28 arranged downstream of the straightening mechanism 23, which is used for counting the length of the straightened reinforcing steel bar. The counting mechanism 28 comprises a counting driving roller 281, a counting driven roller 282 and an encoder 283, wherein the counting driving roller 281 and the counting driven roller 282 can move towards or away from each other along a third direction to clamp the reinforcing steel bar straightened by the straightening mechanism 23, and the encoder 283 is connected to the counting driving roller 281 to determine the length of the straightened reinforcing steel bar by counting the number of rotations of the counting driving roller 281.

[0166] It is worth emphasizing that, in order to reduce the assembly difficulty, the size and shape of the straightening roller seat 233 where any straightening roller 231 is located are the same, that is, the axis of the straightened reinforcing steel bar remains unchanged regardless of the diameter of the straightened reinforcing steel bar. Figure 31 and Figure 32As shown, in order to enable the counting driving wheel 281 and the counting driven wheel 282 to clamp the reinforcing steel bars, the counting mechanism 28 comprises a third adjusting drive 284 and a fourth adjusting drive 285, the output end of the third adjusting drive 284 is connected to the counting driving wheel 281 for driving the counting driving wheel 281 to move in the third direction, and the output end of the fourth adjusting drive 285 is connected to the counting driven wheel 282 for driving the counting driven wheel 282 to move in the third direction. Exemplarily, the third adjusting drive 284 and the fourth adjusting drive 285 are both air cylinders.

[0167] Specifically, in order to improve the stability of the counting driving wheel 281 and the counting driven wheel 282 when moving, the counting mechanism 28 further comprises a first counting plate and a second counting plate, the first counting plate and the second counting plate are spaced apart in the third direction on the straightening frame 21, the counting driving wheel 281 is slidably installed on the first counting plate through a first sliding mounting plate 286, and the counting driving wheel 281 is slidably connected with the first sliding mounting plate 286, and the counting driven wheel 282 is slidably installed on the second counting plate through a second sliding mounting plate 287, and the counting driven wheel 282 is rotatably connected with the second sliding mounting plate 287.

[0168] Based on the arrangement of the counting mechanism 28, in order to better guide the reinforcing steel bars to the counting mechanism 28 and avoid the end of the reinforcing steel bar from sinking under the action of its own gravity, the straightening device 2 further comprises a guide pipe 29 provided on the moving frame 244 for the reinforcing steel bars to pass through, the guide pipe 29 is arranged between the straightening mechanism 23 and the counting mechanism 28, and a plurality of guide pipes 29 are arranged in one-to-one correspondence with the straightening rollers 231.

[0169] In order to prevent foreign matters from affecting the straightening of the reinforcing steel bars during the straightening process, the straightening device 2 further comprises a protective cover, the protective cover covers the entire straightening frame 21 and the traction mechanism 22 and the straightening mechanism 23 therein, and the protective cover is provided with an avoiding hole for the reinforcing steel bars to pass through. Specifically, the guide roller 27 passes out of the protective cover from the avoiding hole. In order to facilitate the maintenance of the traction mechanism 22 and the straightening mechanism 23, the protective cover comprises a main cover body and a movable door, the movable door is slidably arranged on the straightening frame 21 in the first direction to coincide with or be staggered with the main cover body in the third direction, when the movable door is staggered with the main cover body, the protective cover is in a closed state, and when the movable door coincides with the main cover body, the protective cover is in an open state, and the traction mechanism 22 and the straightening mechanism 23 in the protective cover can be maintained.

[0170] Reference Figures 33-35As shown, the shearing device 3 is arranged on the straightening rack 21, and the shearing device 3 comprises a shearing driving member 33, a crank connecting rod mechanism 32 and a shearing mechanism 31. The shearing mechanism 31 comprises a shearing knife seat 311, a knife cylinder 312 and a shearing movable knife 313. The knife cylinder 312 is fixed on the shearing knife seat 311. The knife cylinder 312 is provided with a through hole 3121 for the steel bar to pass through in a first direction. The shearing movable knife 313 is connected to the shearing driving member 33 through the crank connecting rod mechanism 32. The shearing driving member 33 is used to drive the crank connecting rod mechanism 32 to move, and then drive the shearing movable knife 313 to move along the radial direction of the through hole 3121 to approach or move away from the knife cylinder 312, so as to shear the steel bar.

[0171] The shearing device 3 converts the rotary motion of the shearing driving member 33 into the linear motion of the shearing knife rod 324 by using the crank connecting rod mechanism 32. Compared with the traditional hydraulic shearing machine, the manufacturing and maintenance costs are low. Moreover, the knife cylinder 312 itself limits the steel bar, and the positioning device for positioning the steel bar is omitted, so that the shearing device 3 has a simple structure.

[0172] Reference Figure 33 and Figure 34 As shown, the crank connecting rod mechanism 32 comprises a shearing mounting seat 321, an eccentric sleeve 322, a connecting rod 323, a shearing knife rod 324 and a knife rod sleeve 325. The shearing knife seat 311 is fixed on the shearing mounting seat 321. The connecting rod 323 is eccentrically connected to the output end of the shearing driving member through the eccentric sleeve 322, and rotates under the driving of the shearing driving member 33. The shearing knife rod 324 is slidably arranged in the knife rod sleeve 325 fixed on the shearing mounting seat 321 and is rotationally connected with the connecting rod 323. The shearing movable knife 313 is arranged at the end of the shearing knife rod 324 away from the connecting rod 323. Specifically, the connecting rod 323 is sleeved on the eccentric sleeve 322, the eccentric sleeve 322 is sleeved on the output shaft arranged on the output end of the shearing driving member, and the axis of the eccentric sleeve 322 is not coincided with the output shaft, i.e. the eccentric sleeve 322 is arranged eccentrically relative to the output shaft. A bearing is arranged between the eccentric sleeve 322 and the connecting rod 323 to reduce the friction. Meanwhile, the two sides of the eccentric sleeve 322 in the axial direction are provided with a stop washer to axially limit the eccentric sleeve 322.

[0173] When shearing the steel bar, the shearing driving member 33 drives the connecting rod 323 to rotate. During the rotation of the connecting rod 323, the shearing knife rod 324 is pushed to move in the knife rod sleeve 325 to approach or move away from the knife cylinder 312, so as to complete the cutting of the steel bar located in the knife cylinder 312.

[0174] More specifically, the shearing mounting seat 321 comprises first and second support face plates arranged in parallel, and the first and second support face plates are fixedly connected by a connecting column. The shearing knife seat 311 and the knife rod sleeve 325 are both fixedly clamped between the first and second support face plates.

[0175] In addition, the shearing device 3 further comprises a speed reducer and a proximity switch. The shearing driving member 33 is a servo motor, which is connected to an output shaft through the speed reducer to avoid the reciprocating movement of the cutter bar sleeve 325 being too fast. The proximity switch is used to feed back the original position of the shearing driving member 33, so that the shearing driving member 33 can return to the original position through the proximity switch after a long time of work, and the error range value of cutting each set steel bar will be greatly reduced.

[0176] Reference Figure 34 As shown in the figure, in order to reduce the friction between the shearing cutter bar 324 and the cutter bar sleeve 325, bearings are arranged between the shearing cutter bar 324 and the cutter bar sleeve 325, and the cutter bar sleeve 325 is filled with lubricating oil. On this basis, in order to prevent the lubricating oil from leaking, the cutter bar sleeve 325 comprises a sleeve 3251, an end cover 3252 and a sealing ring. The sleeve 3251 is a cylindrical structure with two open ends in the axial direction, and the two ends of the sleeve 3251 are provided with end covers 3252. The end cover 3252 is provided with a mounting hole for the shearing cutter bar 324 to pass through and a receiving groove arranged on the hole wall of the mounting hole. The sealing ring is arranged in the receiving groove and is in interference fit with the cutter bar sleeve 325, that is, the shearing cutter bar 324 and the cutter bar sleeve 325 are in sealed sliding connection.

[0177] Reference Figure 34 As shown in the figure, in order to reduce the difficulty of the steel bar being inserted into the cutter barrel 312, the through hole 3121 comprises a guide section 31212 and a limiting section 31211 connected in the axial direction. The diameter of the limiting section 31211 is the same as the diameter of the steel bar, and the hole diameter of the guide section 31212 gradually increases from one end connected to the limiting section 31211 to the other end. Specifically, the guide section 31212 is arranged at the end of the limiting section 31211 away from the shearing movable cutter 313, so that the steel bar is inserted into the cutter barrel 312 from the end away from the shearing movable cutter 313, thereby improving the shearing efficiency.

[0178] In order to adapt to steel bars of different diameters, the cutter barrel 312 and the shearing cutter seat 311 are detachably connected. In an embodiment, the shearing cutter seat 311 is provided with a mounting hole, and the cutter barrel 312 is inserted into the mounting hole and bolted to the shearing cutter seat 311.

[0179] Reference Figure 35 As shown in the figure, the side of the shearing movable cutter 313 close to the cutter barrel 312 is provided with an arc-shaped blade 3131 concave inward. The stress distribution of the arc-shaped blade 3131 is more uniform, and compared with a flat blade, the possibility of blade collapse caused by local stress concentration is reduced, the wear of the shearing movable cutter 313 is reduced, and the service life of the shearing movable cutter 313 is prolonged.

[0180] Specifically, the shearing movable cutter 313 is connected with the shearing cutter bar 324 in a manner other than bolt connection. On this basis, the shearing movable cutter 313 is provided in a square shape, and an arc-shaped blade 3131 is arranged on each side of the shearing movable cutter 313. When one side of the shearing movable cutter 313 is worn, the shearing movable cutter 313 can be reused by adjusting the direction of the shearing movable cutter 313 relative to the cutter cylinder 312, so that different sides of the shearing movable cutter 313 face the cutter cylinder 312, thereby reducing the cost of shearing steel bars.

[0181] As shown in Figure 36 The straightening device 4 includes a straightening driving member 41, a straightening plate 42, a straightening fixed plate 43, and a straightening shaft 44. The straightening driving member 41 is arranged on the straightening frame 21 through the straightening fixed plate 43, and the output end of the straightening driving member 41 is connected to the straightening plate 42 through a floating joint. The straightening shaft 44 is fixed on the straightening plate 42 and is in sliding connection with a straightening guide rod sleeve 45 arranged on the straightening fixed plate 43.

[0182] As shown in Figure 37 The straightening and bending integrated machine further includes a straightening device 6. The straightening device 6 is used for pre-straightening the steel bars, so as to reduce the difficulty of the steel bars entering the straightening device 2 or the first wire feeding mechanism 25. The straightening device 6 includes a straightening fixed plate 61, a straightening driving member 63, and a handheld handle 65. Two straightening seats 62 are arranged on the straightening fixed plate 61 at intervals. A straightening cavity is arranged through the straightening seats 62 along the interval direction of the straightening seats 62. The two straightening cavities are coaxially arranged, and part of the cavity wall of the straightening cavity faces the straightening fixed plate 61. The straightening driving member 63 is arranged on the straightening fixed plate 61. The output end of the straightening driving member 63 is provided with a top head. The straightening driving member 63 can drive the top head 64 to move along a direction perpendicular to the straightening cavity, so as to abut against or move away from the steel bars penetrating into the straightening cavity. The handheld handle 65 is arranged on the straightening fixed plate 61. A control switch is arranged on the handheld handle 65. The control switch is connected to the straightening driving member 63.

[0183] The straightening device 6 can be held by the handheld handle 65. The steel bars that need to be straightened are placed into the straightening cavity. Then, the control switch on the handheld handle 65 is used to control the straightening driving member 63 to drive the top head 64 to abut against the steel bars in the middle part of the two straightening seats 62 for straightening. The device is simple to operate and does not occupy a large space. The efficiency of straightening is improved, and the space utilization is also improved.

[0184] It should be emphasized that the straightening fixed plate 61, the straightening seat 62, and the handheld handle 65 of the straightening device 6 are all made of light materials, which facilitates personnel operation.

[0185] In some embodiments, the control switch is a push switch, which is convenient for control operation.

[0186] In some embodiments, the straightening seat 62 is a hook fixed on the straightening fixing plate 61, the two hooks are in the same direction, the hook groove of the hook is the straightening cavity mentioned above, and part of the groove wall of the hook groove faces the straightening fixing plate 61. That is, when the steel bar needs to be straightened at a certain point, it is not necessary to pass into the straightening cavity from the end of the steel bar, but can be hooked at the hooking position that needs to be straightened, thereby further improving the straightening efficiency.

[0187] Since the straightening operation adopts two-point support (the contact point of the steel bar and the straightening seat 62) and one-point resistance (the contact end of the steel bar and the top head 64), and the distance between the two support points determines the driving force required by the straightening driving member 63. Based on the above principle, the distance between the two straightening seats 62 is adjustable, so that the position can be adjusted according to different steel bar sizes and different bending degrees and other factors. In some embodiments, the straightening seat 62 is provided with a first mounting hole, and the straightening fixing plate 61 is provided with a plurality of second mounting holes. According to different needs, different second mounting holes are selected, and the straightening seat 62 can be locked and fixed on the other one through the first mounting hole and one of the second mounting holes. Exemplarily, one of the first mounting hole and the second mounting hole is a threaded hole, and the other is a through hole, and the locking member can but is not limited to a bolt.

[0188] In some embodiments, in order to reduce unnecessary interference, the straightening driving member 63 and the straightening seat 62 are arranged on opposite sides of the straightening fixing plate 61, the straightening fixing plate 61 is provided with a through hole, the output end of the straightening driving member 63 is arranged in the through hole, and the top head 64 and the straightening seat 62 are located on the same side of the straightening fixing plate 61.

[0189] In some embodiments, the straightening device 6 further comprises a moving trolley 66, the moving trolley 66 is provided with a hanging rack, the straightening fixing plate 61 can be hung on the hanging rack, so that when it is not needed, it can be hung on the hanging rack, and when it is needed, it can be moved to the position of the steel bar through the moving trolley 66, and then it can be taken down from the hanging rack through the handheld handle 65 to perform the straightening operation.

[0190] In the current embodiment, the hanging rack comprises at least two spaced apart supporting plates, one end of the two supporting plates is fixed on the side wall of the trolley body, and the other end extends away from the trolley body, so that when the straightening fixing plate 61 is placed on the two supporting plates, the straightening driving member 63 is located between the gap formed by the two supporting plates; in order to avoid shaking when being placed, the end of the supporting plate away from the trolley body is further provided with a limiting plate, the limiting plate is arranged at an angle with the supporting plate, and the limiting plate and the side wall of the trolley body form a clamping space to limit the straightening fixing plate 61 in the clamping space. When it is needed, the straightening fixing plate 61 can be lifted by the handheld handle 65.

[0191] In some embodiments, in order to facilitate movement and locking, the bottom wall of the vehicle body is provided with a support leg on one side and a wheel on the other side, so that the vehicle body is supported by the wheel and the support leg, and when movement is needed, the vehicle body is tilted to make the support leg leave the ground.

[0192] The bending device 5 can adopt any bending die replaceable bending machine in the prior art. In some embodiments, the bending device 5 adopts the full-automatic steel bar bending and discharging integrated machine proposed in the prior application (publication number CN119951952A) of the applicant, which integrates the functions of steel bar bending, bending die replacement, and discharging, realizes full-automatic integration of steel bar bending processing, and will not be described here. It is worth emphasizing that based on the above-mentioned full-automatic steel bar bending and discharging integrated machine, the straightening machine frame 21 of the straightening device 2 adopts a right triangle frame, and the moving frame 244 is slidingly arranged on the inclined surface of the straightening machine frame 21.

[0193] The straightening and bending integrated machine in the embodiments of the present application further comprises a transfer device 7 arranged downstream of the bending device 5 for transferring the steel bars.

[0194] As shown in Figure 38 The transfer device 7 comprises a transfer frame 71, a transfer plate 72, a transfer mechanism 73, and a plurality of limiting rod groups. The transfer frame 71 adopts a rectangular frame structure and is connected to the output end of the transfer mechanism 73 to move away from or close to the bending device 5 under the action of the transfer mechanism 73. The transfer plate 72 is laid on the transfer frame 71 to form a support surface for the steel bars to prevent them from falling off. A plurality of limiting rod groups are arranged on the transfer frame 71 along the movement direction of the transfer mechanism 73. Each limiting rod group comprises a plurality of limiting rods 74 arranged along the direction perpendicular to the movement direction of the transfer mechanism 73. The limiting spaces are formed between adjacent limiting rod groups to limit the rolling of the steel bars for batch transfer.

[0195] Specifically, the transfer mechanism 73 can adopt any known driving structure such as a chain wheel driving structure, which will not be described here. It is worth emphasizing that the transfer frame 71 can move to the lower side of the discharging and collecting assembly of the above-mentioned full-automatic steel bar bending and discharging integrated machine.

[0196] According to the above-mentioned straightening and bending integrated machine, the embodiments of the present application further propose a steel bar processing method, which comprises the following steps:

[0197] S1, a plurality of steel bars of different specifications (such as different diameters) are wound on a plurality of pay-off frames 12, the required specification of steel bar is determined, and the corresponding pay-off frame is started.

[0198] Through the plurality of first wire guide mechanisms 13 and the second wire guide mechanisms 15, the steel bars are sequentially inserted, branched, and led out to the wire inlet mechanism 25.

[0199] Specifically, the required specification of steel bar is determined, the corresponding pay-off drive 122 on the pay-off frame 12 is started, the pay-off drive 122 drives the pay-off spindle 123 to rotate, the pay-off spindle 123 drives the pay-off column 125 and the rotating disc 124 to rotate, and the steel bar is payed off at a set speed; the speed control of the rotating disc 124 and the pay-off column 125 is realized by controlling the power of the motor and the speed reducer in the pay-off drive 122, so as to control the release speed of the steel bar. After the pay-off is completed, the pay-off drive 122 is closed, the rotating disc 124 and the pay-off column 125 stop rotating, and the steel bar stops pay-off.

[0200] By arranging the wear-resistant mouth assembly 14, the steel bars on the plurality of pay-off frames 12 can be better distributed and payed off.

[0201] And by arranging the straightening device 6, the steel bar can be better inserted into the first guide mechanism 13 or the feeding mechanism 25.
