DETAILED DESCRIPTION

[0036] In order to make the technical problems, technical solutions and beneficial effects of the utility model clearer, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0037] Please refer to Figures 1 to 7 , a steel bar threading equipment provided by the utility model will be described. The steel bar threading equipment comprises two workbenches 1, a support platform 2 and a steel bar conveying device 3; the two workbenches 1 are arranged at intervals; each workbench 1 is provided with a clamping device 4 and a threading device (not shown in the figure); the support platform 2 is arranged between the two workbenches 1 and is used for supporting steel bars; one side of the support platform 2 is a feeding position and the other side is a discharging position; the steel bar conveying device 3 is arranged on the support platform 2; the steel bar conveying device 3 is used for conveying steel bars to a processing position; wherein the threading devices on the two sides of the support platform 2 are arranged in a staggered manner, the clamping device 4 is arranged correspondingly to the threading devices; the steel bar has a first end and a second end, when the first end of one steel bar is processed by one of the threading devices, the second end of another steel bar is processed by the other threading device at the same time.

[0038] Compared with the prior art, the steel bar threading equipment provided by the utility model can process two steel bars at the same time when processing the threads of the steel bars, the first end of one steel bar is placed on one of the threading devices for processing and the second end of the other steel bar is placed on the other threading device for processing; through the above arrangement, the two threading devices can work at the same time and process different ends of the two steel bars, in the continuous production process, only the positions of the steel bars need to be adjusted forward and backward, for example, the first end of one steel bar is processed by one of the threading devices, after that, the steel bar is moved forward so that the second end of the steel bar can be processed by the other threading device; without rotating the steel bar by 180 degrees, the threads of both ends of the steel bar can be processed, therefore, the above arrangement can reduce the labor intensity.

[0039] It should be noted that the threading device on the workbench 1 is prior art, which will not be described here; the workbench 1 is provided with a cutting machine (not shown in the figure) between the clamping device 4 and the threading device, which can cut the end of the steel bar to make the end of the steel bar more flat.

[0040] For example, for the convenience of description, the threading device close to the feeding position is called the first threading device, and the threading device close to the discharging position is called the second threading device; when the steel bar is just started to be processed, only the first threading device is started, and the first end of the first steel bar is placed into the first threading device, and the first end of the first steel bar is processed by the first threading device.

[0041] After the first end of the first steel bar is processed, the first steel bar is placed to the position aligned with the second threading device, and the second end of the first steel bar is placed into the second threading device, and the second end of the first steel bar is processed by the second threading device; while the second end of the first steel bar is processed by the second threading device, the first end of the second steel bar is processed by the first threading device, so that from the second steel bar, the two threading devices are driven at the same time; the above process is repeated, which can continuously process the steel bar and save processing time and improve processing efficiency.

[0042] For example, the clamping device 4 includes a guide rod 41 fixed on the workbench 1, two clamping components 42 in sliding cooperation with the guide rod 41, and a drive screw 43; the guide rod 41 has a connecting plate 44 at each end, the connecting plate 44 is fixed on the workbench 1, and the guide rod 41 is fixed on the connecting plate 44; both connecting plates 44 have through holes for the drive screw 43 to pass through, the drive screw 43 has threaded holes on both sides of the connecting plate 44, and the drive screw 43 is axially limited by the cooperation of the positioning bolt and the threaded hole. The drive screw 43 has two sections of threads with opposite directions, and the two clamping components 42 have threaded holes with opposite directions, respectively; the two clamping components 42 are respectively matched with the corresponding sections of threads on the drive screw 43; one end of the drive screw 43 extends out of the workbench 1 and has a handle 45; by rotating the handle 45, the drive screw can be rotated, thereby making the two clamping components 42 close to or away from each other, achieving the purpose of clamping or loosening the steel bar.

[0043] In some embodiments, as Figures 1 to 7As shown, the upper loading position of the support platform 2 has an upper loading table 21, and the angle between the upper loading table 21 and the support platform 2 is greater than ninety degrees; both sides of the upper loading table 21 have limiting structures for end-positioned steel bars, and the position of the support platform 2 close to the upper loading table 21 has a first baffle 22 for limiting the steel bars in the lowest position; the limiting structure includes a side plate 23 and a top plate 24, the top plate 24 is fixed on the side plate 23, and the side plate 23 is connected to the upper loading table 21; the top plate 24, the side plate 23 and the upper loading table 21 form an end-positioning space.

[0044] It should be noted that by arranging the upper loading table 21 on the support platform 2, and the angle between the upper loading table 21 and the support platform 2 is greater than ninety degrees, a plurality of steel bars can be placed on the upper loading table 21, and adjacent steel bars are in contact with each other; by arranging the first baffle 22 on the support platform 2, the steel bars in the lowest position of the upper loading table 21 can be limited, avoiding the steel bars on the upper loading table 21 from rolling down to the working position of the support platform 2 and interfering with the steel bars in the working position.

[0045] For example, by arranging the top plate 24 and the side plate 23 on both sides of the upper loading table 21, and the top plate 24, the side plate 23 and the upper loading table 21 form an end-positioning space, the steel bars on the upper loading table 21 can be end-positioned and height-limited, so that the steel bars on the upper loading table 21 can stably stay on the upper loading table 21.

[0046] In some embodiments, as Figures 1 to 7 As shown, the support platform 2 has an avoiding groove 25 opened along the width direction thereof, and the avoiding groove 25 communicates with the front end of the support platform 2; the steel bar conveying device 3 includes a lifting platform 31 arranged below the support platform 2; the lifting platform 31 has a jacking component 32, and the jacking component 32 has three arc-shaped grooves 321 for plug-in cooperation with the steel bars in the upper loading position and the two working positions; wherein the lifting platform 31 can jack up the steel bars, and after moving a preset distance forward, the lifting platform 31 is lowered to reset.

[0047] It should be noted that when the lifting platform 31 moves upward, the steel bars in the upper loading position and the two working positions can be jacked up, and then the lifting platform 31 drives the three steel bars to move forward, which can change the positions of the steel bars, so that the steel bars in the upper loading position are in the position of the first threading device, the steel bars in the original first threading position are in the second threading position, and the steel bars in the original second threading position are in the unloading position; through the above arrangement, the loading and unloading can be synchronized; after the positions are changed, the operator pulls the steel bars in the working positions, and the end portions of the steel bars are in the corresponding threading device positions, which is convenient for thread processing of the end portions of the steel bars.

[0048] For example, a plurality of rollers 26 are rotatably provided on the support platform 2. The axial direction of the rollers 26 is perpendicular to the axial direction of the reinforcing bar. Therefore, when the operator pulls the reinforcing bar, the rollers 26 roll and cooperate with the reinforcing bar, which can reduce friction and make it easier for the operator to pull the reinforcing bar to the threading position.

[0049] In some embodiments, such as Figures 1 to 7 As shown, there are at least two clearance slots 25 spaced apart, and the number of lifting components 32 corresponds one-to-one with the number of clearance slots 25; the attached figure takes three clearance slots 25 as an example, and there are also three lifting components 32 on the lifting platform 31, and all three lifting components 32 are fixed on the lifting platform 31.

[0050] In some embodiments, such as Figures 1 to 7 As shown, the rebar conveying device 3 also includes a movable frame 33 and a transverse drive mechanism; the movable frame 33 is located below the support platform 2; the movable frame 33 is slidably engaged with the support platform 2, and the movable frame 33 has a lifting power component 34, the lifting end of the lifting power component 34 being connected to the lifting platform 31; the transverse drive mechanism is used to drive the movable frame 33 to move laterally along the support platform 2 to convey rebar laterally; a support plate 27 is provided below the support platform 2, and the transverse drive mechanism is set on the support plate 27; the transverse drive mechanism includes a gear 35 and a rack 36, which mesh with each other; the rack 36 is connected to the movable frame 33, the gear 35 is connected to the output shaft of the drive motor 37, and the drive motor 37 is fixed to the support plate 27; a guide post 28 is fixedly provided on the support plate 27, and the movable frame 33 has a through hole that slidably engages with the guide post 28; protrusions 281 are fixedly provided at both ends of the guide post 28, and the protrusions 281 are fixed to the support plate 27. The movable frame 33 has a through hole, and the lifting platform 31 is fixedly provided with a guide component 311, which slides in conjunction with the through hole on the movable frame 33; the above arrangement can improve the stability of the lifting platform 31.

[0051] It should be noted that the lifting power component 34 can be either a pneumatic cylinder or a hydraulic cylinder. After the lifting power component 34 lifts the rebar upwards, the drive motor 37 enables the gear 35 to drive the rack 36, thereby causing the moving frame 33 to slide forward with the lifting platform 31 and the rebar. After sliding into position, the lifting power component 34 returns to its original position, allowing the rebar to re-engage with the support platform 2. At this time, the drive motor 37 drives the moving frame 33 to move backwards, returning it to its initial position. Through the above-described configuration of this application, the purpose of automatically switching the rebar processing position can be achieved, reducing the labor intensity of operators.

[0052] In some embodiments, such as Figures 1 to 7As shown, the side of the support platform 2 in the discharging position has a second baffle 5 for radially limiting the steel bars; the discharging position of the support platform 2 has an inclined surface 29, the high end of the inclined surface 29 is towards the working position, and the bottom end of the inclined surface 29 is towards the second baffle 5; the second baffle 5 is in sliding fit with the support platform 2, and the second baffle 5 is positioned with the support platform 2 through a pin shaft; wherein, when the second baffle 5 limits the steel bars in the radial direction, the top of the second baffle 5 is higher than the top of the support platform 2; after the steel bars are packed, the height of the top of the second baffle 5 is not higher than the top of the support platform 2.

[0053] It should be noted that, since the inclined surface 29 is arranged in the discharging position, the processed steel bars can roll from the high end to the bottom end after falling on the inclined surface 29, and the second baffle 5 limits the steel bars, so as to avoid the situation that the steel bars directly fall from the support platform 2. After the number of steel bars in the discharging position reaches the preset number, the operator can pack the processed steel bars through the avoiding slot 25 on the support platform 2; after the packing is completed, the second baffle 5 is slid downward, so that the top of the second baffle 5 is lower than the top of the support platform 2, and when the steel bars are hoisted by the hoisting equipment, on the one hand, the second baffle 5 can avoid blocking the steel bars, and on the other hand, the impact of the steel bars on the second baffle 5 can be reduced.

[0054] For example, the U-shaped frame 51 is fixed on the support platform 2, and the second baffle 5 is in sliding fit with the U-shaped frame 51; the top of the second baffle 5 has a limiting plate 52, after the second baffle 5 is slid downward to the position, the limiting plate 52 is in contact with the top of the U-shaped frame 51, and the top of the limiting plate 52 is coplanar with the top of the support platform 2. The side wall of the U-shaped frame 51 has a through hole, and the second baffle 5 has a positioning hole aligned with the through hole of the U-shaped frame 51, when the positioning hole is aligned with the through hole of the U-shaped frame 51, the position of the second baffle 5 is fixed through a pin shaft, and the height of the top of the second baffle 5 is higher than the height of the top of the support platform 2, at this time, the second baffle 5 can limit the steel bars in the discharging position.

[0055] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
