Technical Field

[0001] This utility model relates to the field of steel bar production technology, and more specifically, to a straightening device for steel bar production. Background Technology

[0002] To ensure the straightness of the reinforcing bars for easy processing and use, and to eliminate internal residual stress, the reinforcing bars need to be straightened. During the straightening process, the reinforcing bars are usually wound on a sleeve and enter the straightening device one by one. However, after the existing straightening device is completed, because the material is in a single piece, the straightened reinforcing bars need to be manually divided after the straightening is completed. As a result, the straightening efficiency of the existing straightening device is affected by the division. Utility Model Content

[0003] The main purpose of this utility model is to provide a straightening device for steel bar production, which can effectively solve the problem that existing straightening devices require manual cutting of steel bars, resulting in a decrease in straightening efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A straightening device for steel bar production includes a base, a mounting plate fixedly installed on the upper side of the base, a straightening component for straightening steel bars installed on the mounting plate, a feeding component for guiding steel bars installed on one side of the mounting plate, and a sliding groove formed on the upper surface of the base, wherein a dividing component for quantitatively dividing steel bars is slidably installed inside the sliding groove.

[0006] Preferably, the straightening assembly includes a plurality of adjustment holes, which are distributed vertically among each other. Each adjustment hole has a locking seat installed inside it, and a straightening wheel is rotatably installed inside each locking seat.

[0007] Preferably, each straightening wheel is equipped with a transmission gear at its outer end, and the transmission gears on the upper and lower sides mesh with each other. A bracket is fixedly installed on one side of the base, and a drive motor is fixedly installed inside the bracket. The output end of the drive motor is fixedly connected to the adjacent transmission gear.

[0008] Preferably, the feeding assembly includes a mounting platform, which is fixedly mounted on one side of the base, and a guide tube is fixedly mounted on the outside of the mounting platform.

[0009] Preferably, the guide cylinder has an annular groove on its outer side, an annular seat is movably installed inside the annular groove, a buffer spring is installed between the annular seat and the annular groove, and a protective baffle is provided on the outer side of the annular seat.

[0010] Preferably, the dividing assembly includes a movable frame, a sliding seat is installed on the lower side of the movable frame, the sliding seat is slidably installed in the sliding groove, a docking seat is fixedly installed on the outer side of the movable frame, a hydraulic rod is fixedly installed on the upper end of the docking seat, a cutting blade is fixedly installed on the output end of the hydraulic rod, a feeding hole is opened inside the docking seat, and the cutting blade is located inside the feeding hole.

[0011] Preferably, a return spring is provided between one side of the sliding seat and the sliding groove, and a touch switch for controlling the hydraulic rod is fixedly installed on one side of the sliding seat.

[0012] Preferably, a receiving tray is fixedly installed on the outside of the docking seat, a protruding plate is provided on one side of the receiving tray, and a material dropping slope is provided on the upper surface of the receiving tray;

[0013] The convex plate has several positioning holes on its surface. A positioning screw is installed inside the positioning hole. A limit baffle is fixedly installed on one side of the positioning screw, and a locking sleeve is threaded on the other side of the positioning screw.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) By starting the drive motor, one of the transmission gears can be driven to rotate. There are multiple transmission gears arranged in two rows, one above the other. The upper and lower adjacent transmission gears mesh with each other, so that the straightening wheels on both sides rotate at the same time. The upper and lower straightening wheels rotate in different directions, so as to straighten the passing steel bars. The straightening wheels and transmission gears are assembled and connected. After the position of the straightening wheel is adjusted by the locking seat, the corresponding size transmission gear is replaced, so as to realize the corresponding straightening operation for steel bars of different specifications. This application can straighten steel bars of different specifications.

[0016] (2) Before the straightening of the steel bars, the steel bars have different degrees of bending, which causes the rear end of the steel bars to move when the steel bars enter the straightening assembly due to the pressure of the straightening assembly. If there is no protective structure during this process, the steel bars will cause impact or wear to the equipment. Therefore, the guide tube can guide the steel bars into the straightening assembly, and the buffer spring supports the ring seat so that the protective baffle can protect the rear end of the steel bars and prevent the steel bars from directly damaging the equipment.

[0017] (3) After the steel bar is straightened, the straightened end will extend outward. When it extends to the limit baffle, it will push the sliding seat to move inside the sliding groove, so that the touch switch will gradually approach the inner wall of the sliding groove. When it contacts, the touch switch will control the hydraulic rod output end to go down and make the cutting blade divide the current steel bar, realizing the automatic segmentation of the steel bar. After the segmentation, the sliding seat will be reset by the reset spring to facilitate the segmentation of subsequent steel bars.

[0018] (4) In order to achieve quantitative cutting of steel bars, the locking sleeve and the positioning screw can lock the limiting baffle at the current position to prevent the limiting baffle from moving and affecting the cutting when the steel bars are pushed out later. The protruding plate has several positioning holes, and the positioning holes are limited by the length of the steel bars. The positioning screw is inserted into the corresponding positioning hole as needed to achieve quantitative cutting of different lengths. Compared with the existing device that manually cuts after straightening, this application can automatically cut the steel bars after straightening, which effectively improves the efficiency of steel bar processing.

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0028] like Figures 1 to 7 As shown, a straightening device for steel bar production includes a base 1, a mounting plate 2 fixedly installed on the upper side of the base 1, a straightening component 3 for straightening steel bars installed on the body of the mounting plate 2, a feeding component 4 for guiding steel bars installed on one side of the mounting plate 2, a sliding groove 5 opened on the upper surface of the base 1, and a dividing component 6 for quantitatively dividing steel bars slidably installed inside the sliding groove 5.

[0029] In this embodiment, the straightening component 3 includes a plurality of adjustment holes 301, which are distributed vertically among each other. Each adjustment hole 301 is equipped with a locking seat 302, and a straightening wheel 304 is rotatably installed inside the locking seat 302.

[0030] Each straightening wheel 304 has a transmission gear 303 assembled on its outer end. The transmission gears 303 on the upper and lower sides mesh with each other. A bracket 305 is fixedly installed on one side of the base 1. A drive motor 306 is fixedly installed inside the bracket 305. The output end of the drive motor 306 is fixedly connected to the adjacent transmission gear 303.

[0031] By starting the drive motor 306, one of the transmission gears 303 can be rotated. Multiple transmission gears 303 are arranged in two rows, one above the other. The meshing of adjacent transmission gears 303 causes the straightening wheels 304 on both sides to rotate simultaneously. Since the straightening wheels 304 rotate in different directions, they straighten the passing steel bars. The straightening wheels 304 and transmission gears 303 are assembled together. By adjusting the position of the straightening wheels 304 using the locking seat 302 and then replacing them with transmission gears of the corresponding size, straightening operations can be performed on steel bars of different specifications. This application allows for the straightening of steel bars of different specifications.

[0032] In this embodiment, the feeding assembly 4 includes a mounting platform 401, which is fixedly mounted on one side of the base 1, and a guide tube 402 is fixedly mounted on the outside of the mounting platform 401.

[0033] The guide cylinder 402 has an annular groove 403 on its outer side, an annular seat 405 is movably installed inside the annular groove 403, a buffer spring 404 is installed between the annular seat 405 and the annular groove 403, and a protective baffle 406 is provided on the outer side of the annular seat 405.

[0034] Before the steel bars are straightened, the steel bars have varying degrees of bending, which causes the rear end of the steel bars to move due to the pressure of the straightening component 3 when the steel bars enter the straightening component 3. If there is no protective structure during this process, the steel bars will be impacted or worn by the equipment. Therefore, the guide cylinder 402 can guide the steel bars into the straightening component 3, and the buffer spring 404 supports the annular seat 405, so that the protective baffle 406 can protect the rear end of the steel bars and prevent the steel bars from directly damaging the equipment.

[0035] In this embodiment, the dividing component 6 includes a movable frame 601, a sliding seat 6011 is mounted on the lower side of the movable frame 601, the sliding seat 6011 is slidably mounted on the sliding groove 5, a docking seat 605 is fixedly mounted on the outer side of the movable frame 601, a hydraulic rod 606 is fixedly mounted on the upper end of the docking seat 605, a cutting blade 6061 is fixedly mounted on the output end of the hydraulic rod 606, a feeding hole 6051 is opened inside the docking seat 605, and the cutting blade 6061 is located inside the feeding hole 6051.

[0036] A return spring 6013 is provided between one side of the sliding seat 6011 and the sliding groove 5, and a touch switch 6012 for controlling the hydraulic rod 606 is fixedly installed on one side of the sliding seat 6011.

[0037] Among them, a receiving plate 602 is fixedly installed on the outside of the docking seat 605, a protruding plate 603 is provided on one side of the receiving plate 602, and a material dropping slope 6021 is provided on the upper surface of the receiving plate 602.

[0038] The surface of the protruding plate 603 is provided with several positioning holes 6031. A positioning screw 6041 is installed inside the positioning hole 6031. A limit baffle 604 is fixedly installed on one side of the positioning screw 6041, and a locking sleeve 6042 is threaded on the other side of the positioning screw 6041.

[0039] After the rebar is straightened, the straightened end will extend outward. When its end reaches the limit baffle 604, it will push the sliding seat 6011 to move inside the sliding groove 5, so that the touch switch 6012 will gradually approach the inner wall of the sliding groove 5. When it contacts, the touch switch 6012 will control the output end of the hydraulic rod 606 to go down and cause the cutting blade 6061 to cut the current rebar, realizing the automatic segmentation of the rebar. After the segmentation, the sliding seat 6011 will be reset by the reset spring 6013 to facilitate the segmentation of subsequent rebars.

[0040] To achieve quantitative rebar cutting, the locking sleeve 6042 and the positioning screw 6041 are threaded together to lock the limiting baffle 604 at the current position, preventing the limiting baffle 604 from moving and affecting the cutting when the rebar is pushed out later. The protruding plate 603 has several positioning holes 6031 on its surface, and the positioning holes 6031 limit the length of the rebar. The positioning screw 6041 is inserted into the corresponding positioning hole 6031 as needed, thereby realizing quantitative cutting of different lengths. Compared with the existing device that manually cuts after straightening, this application can automatically cut the rebar after straightening, effectively improving the rebar processing efficiency.

[0041] The working principle of this steel bar straightening device:

[0042] In use, the steel bar is first placed into the nearest straightening wheel 304. The steel bar passes through the guide cylinder 402. Then, by starting the drive motor 306, one of the transmission gears 303 can be rotated. There are multiple transmission gears 303 arranged in two rows, one above the other. The upper and lower transmission gears 303 mesh with each other, so that the upper and lower straightening wheels 304 rotate simultaneously. The upper and lower straightening wheels 304 rotate in different directions, so as to straighten the steel bar.

[0043] During the straightening process, the buffer spring 404 supports the ring seat 405, so that the protective baffle 406 can protect the rear end of the steel bar and prevent the steel bar from directly damaging the equipment.

[0044] After straightening, the rebar passes through the feed hole 6051 and then the straightening end extends outward. When its end reaches the limit baffle 604, it pushes the sliding seat 6011 to move inside the sliding groove 5, so that the touch switch 6012 gradually approaches the inner wall of the sliding groove 5. When it contacts, the touch switch 6012 controls the output end of the hydraulic rod 606 to move downward and causes the cutting blade 6061 to divide the current rebar, realizing the automatic segmentation of the rebar, thereby completing the straightening of the rebar.

[0045] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
