Description

Technical Field

[0001] The present invention relates to the technical field of steel bar processing, and particularly relates to a steel bar bending and cutting device for construction equipment. Background Art

[0002] In construction projects, steel bars are a commonly used building material. Steel bars can be combined with concrete to form various reinforced concrete structures. When using steel bars, since steel bars are generally long strips, when combining steel bars into a frame of a certain shape, sometimes it is necessary to use a steel bar bending and cutting device to bend the steel bars into a certain shape and cut the bent steel bars. Then, the steel bars of a certain shape cut out can be combined into a frame. When the existing steel bar bending and cutting device is in use, generally two bending rods are provided. After the steel bar is conveyed between the two bending rods, one bending rod can be rotated around the other bending rod, so as to bend the steel bar in one direction. If the steel bar is to have two bending directions in opposite directions, such as bending the steel bar into a Z shape, after one bending, the steel bar needs to be rotated, and then the bending directions of the two times of the steel bar can be different. However, when batch-bending steel bars, the distance between adjacent two steel bars is relatively close. When rotating the steel bar, the steel bars may block each other, which is not conducive to the batch-bending of steel bars. Summary of the Invention

[0003] In order to overcome the above technical problems, the purpose of the present invention is to provide a steel bar bending and cutting device for construction equipment. A linkage rod is rotationally connected through a sliding rod, which can make the linkage rod rotate forward, make the connecting plate rotate around the round rod located at the top, and the bending rod located at the bottom can rotate around the bending rod located at the top, so as to bend the steel bar upward. And the linkage rod can be rotated reversely, so that the bending rod can bend the steel bar downward, so that the steel bar has bent angles with different bending directions, and there is no need to rotate the steel bar, which is convenient for batch-bending of steel bars.

[0004] The purpose of the present invention can be realized by the following technical solutions:

[0005] A steel bar bending and cutting device for construction equipment workers, comprising a bending module and a support module. The bending module includes two adjustment frames, and two bending rods are arranged between the two adjustment frames. The support module includes two fixed shells. The bending module is located between the two fixed shells. A sliding rod is slidably connected to the inner side of the fixed shell. The bottom of the inner side of the sliding rod is rotatably connected to a linkage rod fixedly connected to the adjacent adjustment frame. One end of the linkage rod is located inside the fixed shell and fixedly connected to a connecting plate. Both the top and bottom of the side of the connecting plate are fixedly connected with round rods. Two first limiting rails are arranged inside the fixed shell. The side surfaces of the two first limiting rails are fixedly connected with a second limiting rail fixedly connected to the inner side of the fixed shell. A sliding block is rotatably connected to the side of the round rod. The inner side surfaces of the second limiting rail and the first limiting rail at the bottom are both slidably connected to the side of the adjacent sliding block. A cutting knife is arranged between the two fixed shells. It can make the linkage rod rotate, and the linkage rod can drive the connecting plate and the adjustment frame to rotate. Since the first limiting rail and the second limiting rail can limit the moving range of the round rod inside them, when the connecting plate rotates, it will rotate around the round rod at the top or the round rod at the bottom. The axes of the bending rod and the round rod at the same height are on the same straight line. In this way, the bending rod at the bottom can rotate around the bending rod at the top, or the bending rod at the top can rotate around the bending rod at the bottom, so as to bend the steel bar upward or downward, so that the steel bar has bent angles with different bending directions, and it is not necessary to rotate the steel bar, which is convenient for batch bending of steel bars. After bending, the cutting knife can be moved downward to cut off the steel bar. The first limiting rail is located between the second limiting rail and the connecting plate. When the round rod at the top moves along the second limiting rail, it can pass through between the two first limiting rails.

[0006] Furthermore, adjustment blocks are slidably connected to both the top and bottom inner side surfaces of the adjustment frame. Threaded rods rotatably connected to the adjacent adjustment blocks are rotatably connected to both the top and bottom inner side surfaces of the adjustment frame. The side of the adjustment block is fixedly connected with a socket. Both ends of the bending rod are fixedly connected with plug blocks slidably inserted into the adjacent socket. A positioning screw is threadedly connected to the side of the socket and threadedly connected to the adjacent plug block. The positioning screw can connect the plug block and the socket. The adjustment frame can drive the bending rod to rotate through the adjustment block, the socket and the plug block. The positioning screw can be screwed out. At this time, the plug block can be moved upward to disengage from the socket, and then the bending rod with a corresponding diameter can be replaced according to needs, so as to adapt to steel bars with different diameters. After replacing the bending rod with a different diameter, the threaded rod can be rotated to adjust the position of the corresponding bending rod, so as to adjust the distance between the two bending rods, so as to change the radian of the bent part of the steel bar when bending upward. It is more flexible to use and convenient to use.

[0007] Furthermore, grid frames are provided at the top and bottom of the adjustment frame, and both ends of the grid frames are fixedly connected to the sides of the adjacent fixed shells. When the steel bars are bent, they can be inserted into the gaps corresponding to the grid frames, so that the angles of the steel bars are maintained by the grid frames to avoid bending of the steel bars. In this way, the bending directions of the steel bars can be completely opposite, which is beneficial to improving the bending effect.

[0008] The cam is an adjustable speed gear, and the adjustable speed gear is connected to the adjustable gear of the vehicle frame by the adjustment means.

[0009] The further feature is that: the inner side surface of the sliding rod is rotatably connected to a rotating rod, the side surface of the linkage rod and the bottom of the side surface of the rotating rod are fixedly sleeved with a bevel gear, and the two bevel gears are meshed for transmission, the inner side surface of the sliding rod is slidably connected to a connecting rod, the top surface of the fixed shell is provided with an open groove slidably connected to the side surface of the connecting rod, the inner side surface of the connecting rod is rotatably connected to a transmission rod, the bottom end of the transmission rod is fixedly connected to a rectangular rod slidably connected to the inner side surface of the rotating rod, the transmission rod can drive the rectangular rod to rotate, the rectangular rod can drive the rotating rod to rotate, the rotating rod can drive the linkage rod to rotate through the bevel gear, and when the linkage rod rotates, it can rotate around the round rod located at the top or bottom, at this time the linkage rod can drive the sliding rod to move, so that the sliding rod moves closer to or away from the connecting rod, and the sliding rod pushes the connecting rod to move horizontally, so that the connecting rod slides in the open groove, and the rotating rod can slide along the rectangular rod.

[0010] Furthermore, a connecting frame is fixedly connected to the top surface of the fixed housing corresponding to the opening groove. The inner side surface of the connecting frame is slidably connected to the top of the side surface of the connecting rod. The top of the inner side surface of the connecting rod is rotatably connected to a driving rod. Conical gears II are fixedly sleeved on the side surfaces of the driving rod and the transmission rod, and the two conical gears II are meshed and driven. The inner side surface of the connecting frame is rotatably connected to a rotating shaft. One end of the connecting rod is provided with a driving motor fixedly connected to the top surface of the fixed housing, and the output end of the driving motor is drivingly connected to one end of the rotating shaft. The other end of the rotating shaft is fixedly connected to a rectangular rod II. The side surface of the rectangular rod II is slidably connected to the side surface of the driving rod. The other ends of the two connecting rods are fixedly connected to a side frame. Both ends of the inner side surface of the side frame are rotatably connected to a support rod, and one end of the support rod is fixedly connected to the end of the adjacent rectangular rod II. The driving motor can drive the rotating shaft to rotate, the rotating shaft can drive the rectangular rod II to rotate, the rectangular rod II can drive the driving rod to rotate, and the driving rod can drive the transmission rod to rotate through the conical gear II, so as to drive the linkage rod to rotate. When the sliding rod pushes the connecting rod to move horizontally, the connecting rod can drive the driving rod to move, so that the driving rod slides on the rectangular rod II, and the driving motor can always drive the linkage rod to rotate.

[0011] Furthermore, two fixed seats fixedly connected to the adjacent fixed housing are arranged on the top of the cutting knife. A hydraulic rod is fixedly connected to the bottom surface of the fixed seat. A top plate is fixedly connected to the top surface of the cutting knife, and the output ends of the two hydraulic rods are both drivingly connected to the top surface of the top plate. A bottom plate fixedly connected to the fixed housing is arranged on the bottom surface of the cutting knife. The bottom plate can support the steel bar. The hydraulic rod drives the top plate to move downward, so that the cutting knife moves downward to cut off the steel bar.

[0012] Furthermore, two conveying rods are arranged on the opposite surfaces of the two fixed housings, and a power motor is arranged inside one of the fixed housings. The output end of the power motor is drivingly connected to the end of the conveying rod at the bottom. The cutting knife is located between the conveying rod and the bending rod, and the power motor can drive the conveying rod at the bottom to rotate, so as to convey the steel bar by the conveying rod.

[0013] The beneficial effects of the present invention:

[0014] 1. By rotatably connecting the sliding rod with the linkage rod, the linkage rod can rotate forward. The linkage rod can drive the connecting plate to rotate. Since the limiting rail II can limit the moving range of the round rod at the top, the connecting plate will rotate around the round rod at the top, so that the adjusting frame drives the two bending rods to rotate, the round rod at the bottom moves along the inside of the limiting rail I, and the bending rod at the bottom rotates around the bending rod at the top, so as to bend the steel bar upward. And the linkage rod can rotate reversely, so that the connecting plate can rotate around the round rod at the bottom, and the bending rod bends the steel bar downward, so that the steel bar has bent angles with different bending directions, and the steel bar does not need to be rotated, which is convenient for batch bending of the steel bar;

[0015] 2. The rectangular rod 1 is slidably connected to the inner side of the rotating rod. The rectangular rod 1 can drive the rotating rod to rotate, and the connecting rod can slide within the connecting frame and drive the driving rod to rotate through the rectangular rod 2, so that the linkage rod can always be driven to rotate by the fixedly arranged power motor.

[0016] 3. By sliding the plug-in block into the plug-in socket, the positioning screw can be unscrewed, so that the bending rod with the corresponding diameter can be replaced as needed, thus adapting to steel bars with different diameters. After replacing the bending rod with a smaller diameter, the screw rod can be rotated to adjust the position of one bending rod, thereby adjusting the distance between the two bending rods. In this way, when the steel bar is bent upward, the arc of the bending part of the steel bar can be adjusted as needed. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] Please refer to Figures 1-14As shown in the figure, a steel bar bending and cutting device for construction equipment workers includes a bending module 100 and a support module 200. The bending module 100 includes two adjustment frames 130. Between the two adjustment frames 130, there are two bending rods 110. The support module 200 includes two fixed shells 210. The bending module 100 is located between the two fixed shells 210. The inner side of the fixed shell 210 is slidably connected with a sliding rod 250. The bottom of the inner side of the sliding rod 250 is rotatably connected with a linkage rod 251 fixedly connected to the adjacent adjustment frame 130. One end of the linkage rod 251 is located inside the fixed shell 210 and fixedly connected with a connecting plate 220. The top and bottom of the side of the connecting plate 220 are both fixedly connected with round rods 221. Inside the fixed shell 210, there are two first limiting rails 230. The sides of the two first limiting rails 230 are fixedly connected with a second limiting rail 240 fixedly connected to the inner side of the fixed shell 210. The side of the round rod 221 is rotatably connected with a sliding block 222. The inner sides of the second limiting rail 240 and the first limiting rail 230 at the bottom are both slidably connected with the side of the adjacent sliding block 222. Between the two fixed shells 210, there is a cutting knife 300, which can make the linkage rod 251 rotate. The linkage rod 251 can drive the connecting plate 220 and the adjustment frame 130 to rotate. Since the first limiting rail 230 and the second limiting rail 240 can limit the moving range of the round rod 221 inside them, when the connecting plate 220 rotates, it will rotate around the round rod 221 at the top or the round rod 221 at the bottom. The axes of the bending rod 110 and the round rod 221 at the same height are on the same straight line. In this way, the bending rod 110 at the bottom can rotate around the bending rod 110 at the top, or the bending rod 110 at the top can rotate around the bending rod 110 at the bottom, so as to bend the steel bar upward or downward, so that the steel bar has bend angles with different bending directions, and there is no need to rotate the steel bar, which is convenient for batch bending of steel bars. After bending, the cutting knife 300 can be moved downward to cut off the steel bar. The first limiting rail 230 is located between the second limiting rail 240 and the connecting plate 220. When the round rod 221 at the top moves along the second limiting rail 240, it can pass through between the two first limiting rails 230.

[0035] Adjusting blocks 131 are slidably connected to both the inner sides of the top and bottom of the adjusting frame 130. Lead screws 132 that are rotationally connected to the inner sides of the top and bottom of the adjusting frame 130 and are screwed to the adjacent adjusting blocks 131 are provided. A socket 133 is fixedly connected to the side of the adjusting block 131. Plug blocks 111 that are slidably inserted into the adjacent sockets 133 are fixedly connected to both ends of the bent rod 110. A positioning screw 140 that is screwed to the side of the socket 133 and is screwed to the adjacent plug block 111 is provided. The positioning screw 140 can connect the plug block 111 and the socket 133. The adjusting frame 130 can drive the bent rod 110 to rotate through the adjusting block 131, the socket 133, and the plug block 111. The positioning screw 140 can be unscrewed. At this time, the plug block 111 can be moved upward to disengage from the socket 133. Then, the bent rod 110 with a corresponding diameter can be replaced as needed, so as to adapt to steel bars with different diameters. After replacing the bent rod 110 with a different diameter, the lead screw 132 can be rotated to adjust the position of the corresponding bent rod 110, thereby adjusting the distance between the two bent rods 110. In this way, the radian of the bent part of the steel bar when bent upward can be changed. It is relatively flexible to use and convenient for use.

[0036] Grid bar frames 120 are provided at both the top and bottom of the adjusting frame 130, and both ends of the grid bar frame 120 are fixedly connected to the side of the adjacent fixed shell 210. When the steel bar is bent, it can be inserted into the corresponding gap of the grid bar frame 120, so as to maintain the angle of the steel bar through the grid bar frame 120 and prevent the steel bar from being bent. In this way, the bending directions of the steel bars can be completely opposite, which is beneficial to improving the bending effect.

[0037] A support frame 211 is fixedly connected to the bottom surface of the fixed shell 210. A fixed frame 231 that is fixedly connected to the inner side of the fixed shell 210 is fixedly connected to the side of the first limiting rail 230. A limiting groove 212 corresponding to the adjacent adjusting frame 130 is provided on the side of the fixed shell 210, and the linkage rod 251 passes through the inside of the adjacent limiting groove 212. A sliding frame 213 is slidably connected to the inner side of the limiting groove 212. A rectangular block 214 that is rotationally connected to the side of the adjacent linkage rod 251 is slidably connected to the inner side of the sliding frame 213, and the side of the rectangular block 214 is fixedly connected to the bottom of the side of the adjacent sliding rod 250. The support frame 211 can support the fixed shell 210. The bottoms of the two support frames 211 can be connected by a steel plate, which is beneficial to improving the stability of the support. The fixed frame 231 can support the first limiting rail 230. The sliding frame 213 can slide up and down in the limiting groove 212. The rectangular block 214 can slide horizontally in the sliding frame 213, so as to limit the angle of the sliding rod 250 through the rectangular block 214 and prevent the sliding rod 250 from rotating.

[0038] The inner side of the sliding rod 250 is rotatably connected with a rotating rod 252. A first bevel gear 253 is fixedly sleeved on the side surface of the linkage rod 251 and the bottom of the side surface of the rotating rod 252, and the two first bevel gears 253 are in meshing transmission. The inner side of the sliding rod 250 is slidably connected with a connecting rod 260. An opening groove for the side surface of the connecting rod 260 to slide is formed in the top surface of the fixed housing 210. The inner side of the connecting rod 260 is rotatably connected with a transmission rod 261. A first rectangular rod 262 which is slidably connected with the inner side of the rotating rod 252 is fixedly connected to the bottom end of the transmission rod 261. The transmission rod 261 can drive the first rectangular rod 262 to rotate, the first rectangular rod 262 can drive the rotating rod 252 to rotate, and the rotating rod 252 can drive the linkage rod 251 to rotate through the first bevel gear 253. When the linkage rod 251 rotates, it can rotate around the round rod 221 located at the top or bottom. At this time, the linkage rod 251 can drive the sliding rod 250 to move, so that the sliding rod 250 moves closer to or away from the connecting rod 260, and the sliding rod 250 can push the connecting rod 260 to move horizontally, so that the connecting rod 260 slides in the opening groove, and the rotating rod 252 can slide along the first rectangular rod 262.

[0039] A connection frame 270 is fixedly connected to the top surface of the fixed housing 210 corresponding to the opening groove. The inner side of the connection frame 270 is slidably connected with the top of the side surface of the connecting rod 260. A driving rod 263 is rotatably connected to the top of the inner side of the connecting rod 260. A second bevel gear 264 is fixedly sleeved on the side surface of the driving rod 263 and the top of the side surface of the transmission rod 261, and the two second bevel gears 264 are in meshing transmission. A rotating shaft 272 is rotatably connected to the inner side of the connection frame 270. One end of the connecting rod 260 is provided with a driving motor 273 fixedly connected to the top surface of the fixed housing 210, and the output end of the driving motor 273 is in transmission connection with one end of the rotating shaft 272. A second rectangular rod 271 is fixedly connected to the other end of the rotating shaft 272. The side surface of the second rectangular rod 271 is slidably connected with the side surface of the driving rod 263. The other ends of the two connecting rods 260 are fixedly connected with a side frame 280. Both ends of the inner side of the side frame 280 are rotatably connected with a support rod 281, and one end of the support rod 281 is fixedly connected to the end of the adjacent second rectangular rod 271. The driving motor 273 can drive the rotating shaft 272 to rotate, the rotating shaft 272 can drive the second rectangular rod 271 to rotate, the second rectangular rod 271 can drive the driving rod 263 to rotate, and the driving rod 263 can drive the transmission rod 261 to rotate through the second bevel gear 264, so as to drive the linkage rod 251 to rotate. When the sliding rod 250 pushes the connecting rod 260 to move horizontally, the connecting rod 260 can drive the driving rod 263 to move, so that the driving rod 263 slides on the second rectangular rod 271. The driving motor 273 can always drive the linkage rod 251 to rotate. A sprocket can be arranged on the support rod 281, and the sprockets on the two support rods 281 are connected by a chain transmission, so that the two second rectangular rods 271 can rotate synchronously, and only one driving motor 273 can be arranged.

[0040] At the top of the cutting knife 300, there are two fixing seats 310 fixedly connected to the adjacent fixed shell 210. The bottom surface of the fixing seat 310 is fixedly connected with a hydraulic rod 320. The top surface of the cutting knife 300 is fixedly connected with a top plate 330. And the output ends of the two hydraulic rods 320 are both drivingly connected to the top surface of the top plate 330. On the bottom surface of the cutting knife 300, there is a supporting plate 340 fixedly connected to the fixed shell 210. The supporting plate 340 can support the steel bar. The hydraulic rod 320 drives the top plate 330 to move downward, so that the cutting knife 300 moves downward to cut off the steel bar.

[0041] On the opposite surfaces of the two fixed shells 210, there are two conveying rods 400. And inside one of the fixed shells 210, there is a power motor 500. The output end of the power motor 500 is drivingly connected to the end of the conveying rod 400 at the bottom. The cutting knife 300 is located between the conveying rod 400 and the bending rod 110. By driving the conveying rod 400 at the bottom to rotate through the power motor 500, the conveying rod 400 can convey the steel bar. The conveying rod 400 at the bottom can be rotatably arranged on the fixed shell 210, and a sliding seat slidably connected to the fixed shell 210 is arranged at the end of the conveying rod 400 at the top. The conveying rod 400 and the sliding seat are rotatably connected by a shaft rod. In this way, the distance between the two conveying rods 400 can be adjusted as needed to adapt to steel bars of different diameters.

[0042] Working principle: When in use, several steel bars are passed through between two conveying rods 400. The conveying rod 400 at the bottom is driven to rotate by the power motor 500, so that the conveying rod 400 conveys the steel bars. The steel bars can pass through between the cutting knife 300 and the abutting plate 340, and then pass into between two bending rods 110. After the steel bars are conveyed forward by a certain distance, the driving motor 273 can be started. The driving motor 273 can drive the rotating shaft 272 to rotate. The rotating shaft 272 can drive the second rectangular rod 271 to rotate. The second rectangular rod 271 can drive the driving rod 263 to rotate. The driving rod 263 can drive the transmission rod 261 to rotate through the second bevel gear 264. The transmission rod 261 can drive the first rectangular rod 262 to rotate. The first rectangular rod 262 can drive the rotating rod 252 to rotate. The rotating rod 252 can drive the linkage rod 251 to rotate through the first bevel gear 253, so that the linkage rod 251 rotates forward. The linkage rod 251 can drive the adjusting frame 130 and the connecting plate 220 to rotate. Since the second limiting rail 240 can limit the moving range of the round rod 221 and the sliding block 222 at the top, when the linkage rod 251 drives the connecting plate 220 to rotate forward, the connecting plate 220 can rotate around the round rod 221 at the top, so that the round rod 221 and the sliding block 222 at the bottom slide along the two first limiting rails 230. The adjusting frame 130 can drive the bending rod 110 to rotate through the plugging seat 133 and the plugging block 111. In this way, when the axis of the bending rod 110 and the axis of the round rod 221 at the same height are on the same straight line, the two bending rods 110 can both rotate around the axis of the bending rod 110 at the top, so that the bending rod 110 at the bottom rotates upward around the bending rod 110 at the top, thereby bending the steel bar upward;

[0043] After one bending of the steel bar is completed, the driving motor 273 drives the rotating shaft 272 to rotate in the reverse direction, rotates the bending rod 110 at the bottom to the original angle. After the steel bar is conveyed forward by a certain distance, the driving motor 273 continues to drive the rotating shaft 272 to rotate in the reverse direction. At this time, the linkage rod 251 can rotate in the reverse direction. Since the first limiting rail 230 can limit the moving range of the round rod 221 at the bottom, at this time, the connecting plate 220 can rotate around the round rod 221 at the bottom, so that the round rod 221 and the sliding block 222 at the top rotate along the second limiting rail 240. The round rod 221 at the top can pass through between the two first limiting rails 230, so that the two bending rods 110 both rotate around the axis of the bending rod 110 at the bottom, so that the bending rod 110 at the top rotates around the bending rod 110 at the bottom, thereby bending the steel bar downward. Then, the bending rod 110 can be rotated back to the original position, and the steel bar can be continuously conveyed for bending. After the bending is completed, the hydraulic rod 320 can drive the top plate 330 to move downward, so that the cutting knife 300 moves downward. The abutting plate 340 can support the steel bar. In this way, when the cutting knife 300 moves downward, the steel bar can be cut off, and then the steel bar can be continuously conveyed for bending.
