Description

Technical Field

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

[0002] In existing straightening devices, grooved rollers are mainly used to compress and straighten stainless steel bars. However, after a stainless steel bar is processed, the rollers will squeeze each other when the steel bar is no longer blocking them, making it difficult to feed the next steel bar.

[0003] Therefore, it is necessary to provide a straightening device for stainless steel bars to solve the above problems. Summary of the Invention

[0004] Based on the aforementioned problems in the prior art, the purpose of this application is to provide a straightening device for stainless steel bars, thereby facilitating material feeding.

[0005] The technical solution adopted by this application to solve its technical problem is as follows: a straightening device for stainless steel bars, including a bracket, a support plate fixed to one side of the bracket, a fixing block fixed to one side of the lower end of the support plate, a plurality of fixing wheels rotatably arranged on the side of the fixing block away from the support plate, two fixing bushings fixed to one side of the upper end of the support plate, a lifting shaft slidably arranged inside each fixing bushing, a limit block fixed between the upper ends of the lifting shafts, the limit block being located on the upper side of the fixing bushings, a movable plate arranged on one side of the support plate, both ends of the movable plate being penetrated by the lower ends of the lifting shafts, the movable plate being slidably connected to the lifting shafts, the movable plate being located on the lower side of the fixing bushings, and a plurality of movable wheels rotatably arranged on the side of the movable plate away from the support plate.

[0006] Furthermore, a pressing plate is provided on one side of the support plate, and both ends of the pressing plate are penetrated by the lower end of the lifting shaft. The pressing plate is slidably connected to the lifting shaft. The pressing plate is located between the movable plate and the fixed bushing. The rotating wheel is located between the pressing plate and the limiting block. Several elastic elements are fixed at the upper end of the movable plate.

[0007] Furthermore, a driver is fixed to the side of the support plate away from the rotating wheel, and the output shaft of the driver is fixed to the rotating shaft.

[0008] Furthermore, a rotating shaft is rotatably mounted on the support plate, and a rotating wheel is eccentrically fixed at one end of the rotating shaft, with the rotating wheel located below the limiting block.

[0009] Furthermore, a stop is provided at the lower end of the lifting shaft.

[0010] The beneficial effects of this utility model are:

[0011] The lifting shaft is raised by the limit block, so that the movable plate and the movable wheel rise together, and then the movable plate and the movable wheel are separated. This makes it convenient to let one end of the steel rod pass between the fixed wheel and the movable wheel and then extend into the conveying equipment before processing begins.

[0022] like Figure 1-3As shown, this application provides a straightening device for stainless steel bars, including a bracket, a support plate 1 fixed on one side of the bracket, a fixing block 11 fixed on one side of the lower end of the support plate 1, and a plurality of fixing wheels 12 rotatably arranged on the side of the fixing block 11 away from the support plate 1.

[0023] Two fixed bushings 13 are fixed on one side of the upper end of the support plate 1. A lifting shaft 2 is slidably arranged inside each fixed bushing 13. A limit block 21 is fixed between the upper ends of the lifting shafts 2. The limit block 21 is located on the upper side of the fixed bushing 13.

[0024] A movable plate 22 and a pressing plate 23 are provided on one side of the support plate 1. Both ends of the movable plate 22 and the pressing plate 23 are penetrated by the lower end of the lifting shaft 2, and the movable plate 22 and the pressing plate 23 are slidably connected to the lifting shaft 2. The movable plate 22 is located on the lower side of the fixed bushing 13, and the pressing plate 23 is located between the movable plate 22 and the fixed bushing 13.

[0025] The movable plate 22 is rotatably provided with several movable wheels 24 on the side away from the support plate 1, and several elastic elements 25 are fixed at the upper end of the movable plate 22. In this embodiment, the elastic elements 25 are springs.

[0026] A stop 26 is provided at the lower end of the lifting shaft 2.

[0027] A rotating shaft 14 is rotatably mounted on the support plate 1. A rotating wheel 15 is eccentrically fixed at one end of the rotating shaft 14. The rotating wheel 15 is located between the extrusion plate 23 and the limiting block 21. A driver 16 is fixed on the side of the support plate 1 away from the rotating wheel 15. In this embodiment, the driver 16 is a motor, and the output shaft of the driver 16 is fixed to the rotating shaft 14.

[0028] like Figure 1 As shown, a conveying device is installed on the bracket. After the steel bar passes between the fixed wheel 12 and the movable wheel 24, it extends into the conveying device. The conveying device is used to pull the steel bar and to straighten it by squeezing the steel bar through the grooves on the fixed wheel 12 and the movable wheel 24.

[0029] The driver 16 is used to drive the rotating wheel 15 to rotate via the rotating shaft 14, since the rotating wheel 15 is eccentrically fixed to the rotating shaft 14. When the rotating shaft 14 rotates, it will change the eccentric direction of the rotating wheel 15, causing the rotating wheel 15 to protrude to the eccentric side.

[0030] like Figure 2As shown, when the rotating wheel 15 protrudes upward, the rotating wheel 15 will push the lower side of the limiting block 21, causing the limiting block 21 to drive the lifting shaft 2 to rise, thereby causing the stop block 26 to drive the movable plate 22 and the movable wheel 24 to rise together, thus separating the movable plate 22 and the movable wheel 24. This makes it convenient to let one end of the steel rod pass between the fixed wheel 12 and the movable wheel 24 and then extend into the conveying equipment before processing begins.

[0031] After the steel bar is placed, the driver 16 drives the rotating wheel 15 to rotate, gradually causing it to protrude downwards. During rotation, as the height of the upper part of the rotating wheel 15 decreases, the weight of the lifting shaft 2 and the limiting block 21 causes the stop block 26, the movable plate 22, and the movable wheel 24 to descend until the movable wheel 24 presses against the steel bar. At this point, supported by the steel bar and with the sliding connection between the movable plate 22 and the lifting shaft 2, the movable plate 22 and the movable wheel 24 will not continue to descend. As the rotating wheel 15 gradually protrudes downwards, it eventually presses against the pressing plate 23, causing the pressing plate 23 to compress the elastic element 25, thereby pushing the movable plate 22 and increasing the pressure of the movable wheel 24 on the steel bar. The more the rotating wheel 15 protrudes downwards, the greater the pressure of the movable wheel 24 on the steel bar, which can accommodate thinner or harder steel bars; the less the rotating wheel 15 protrudes downwards, the less the pressure of the movable wheel 24 on the steel bar, which can accommodate thicker or softer steel bars. This allows for adjusting the pressure of the movable wheel 24 on the steel bar by adjusting the direction of the rotating wheel 15, thus adapting to steel bars of different thicknesses and hardnesses.
