Description

Technical Field

[0002] Steel bars are an important material commonly used in construction projects. They are mainly used to enhance the tensile strength of concrete to improve the bearing capacity and durability of the structure. When used, steel bars are mostly used in a bent form. When they are subsequently recycled, the recycled steel bars need to be straightened. Traditionally, the straightening of recycled steel bars is done by transferring the rolled steel bars to a straightening device with staggered straightening wheels for straightening. However, due to the bent state of the recycled steel bars, they will still be bent after being directly put into the straightening device for straightening. Multiple straightening operations are required to completely straighten the steel bars. In addition, the outer diameters of the recycled steel bars are different, and the spacing of the straightening wheels needs to be adjusted to match them, which affects the overall straightening efficiency of the steel bars.

[0013] A method for using a straightening device for steel bar processing comprises the following steps: Step 1: Connect the end of the connector to the output port of the cleaning agent output system. In the initial state, the transmission rack and the driving gear are meshed. Then, according to the outer diameter of the waste recycled steel bars, a feed slot with a suitable aperture size is selected. The first linear electric rail is controlled to drive the initial calibration component to move horizontally, and the positions of multiple feed slots are flexibly adjusted so that the feed slots with corresponding aperture sizes correspond horizontally to the positions of the feed pipes. While the initial calibration outer frame moves horizontally to adjust the positions of multiple feeding slots, the transmission rack is driven to move synchronously through the connection of the auxiliary seat and the telescopic cylinder. The transmission rack drives the two driving gears to rotate synchronously, thereby controlling the synchronous rotation of the co-driving shafts on both sides and multiple worms on the same side, thereby controlling the synchronous rotation of the corresponding worm gears and adjusting screws. Since the adjusting screw threads are installed in the corresponding card-slip sleeves, the first straightening bevel rollers and the second straightening bevel rollers on both sides are driven to move synchronously towards each other, and the distance between the first straightening bevel rollers and the second straightening bevel rollers is synchronously reduced, which has been adapted to the secondary straightening operation of steel bars with different aperture sizes. Then, the telescopic cylinder is controlled to drive the transmission rack to move horizontally, so that the transmission rack can be separated from the driving gear; Step 2: insert the recycled steel bars into the feed slot of the corresponding aperture size, and then pass them through the two drive rollers in the corresponding position drive members in the first drive assembly and the second drive assembly, and pass them through the straightening rollers in the primary calibration bottom frame and the primary calibration top frame in the corresponding position in the primary calibration member, and control the first motor in the first drive assembly and the second drive assembly to start, cooperate with the meshing connection of the two transmission gears, drive the two vertical corresponding drive rollers to rotate synchronously in opposite directions, control the steel bars placed between the two drive rollers to be automatically transmitted, and while the steel bars are automatically transmitted, cooperate with the staggered straightening rollers to perform automatic primary straightening operations; Step 3: After the primary straightening operation of the steel bar is completed, the steel bar is immediately introduced into the secondary straightening outer frame through the feed pipe, and passes through a plurality of first straightening bevel rollers and second straightening bevel rollers, and the steel bar after the primary straightening contacts the outer walls of the first straightening bevel rollers and the second straightening bevel rollers; At the same time, the second motor is controlled to start and drive the horizontal axis to rotate, and the first sprocket, the second sprocket and the transmission chain are coordinated to control the feed pipe and the secondary outer frame and the plurality of first straightening inclined rollers, the second straightening inclined rollers and the cleaning scraper to rotate at high speed, and the steel bars after primary straightening are automatically transmitted in the secondary outer frame, and the plurality of first straightening inclined rollers and the second straightening inclined rollers perform secondary straightening on the steel bars; At the same time, the cleaning agent output system is controlled to start. The cleaning agent is introduced into multiple liquid spray frames through the connector, the inner ring cylinder, the outer ring cylinder, the connecting pipe, the liquid guide main pipe and multiple liquid guide branch pipes, and is evenly sprayed on the surface of the steel bar through multiple cleaning spray holes. With the high-speed rotation of the cleaning scraping brush, the steel bar is cleaned synchronously. Step 4: After the secondary straightening, the steel bar passes through the secondary straightening outer frame and is placed between the two driving rollers in the corresponding position driving member in the third driving assembly. The two vertical corresponding driving rollers in the third driving assembly are controlled to rotate synchronously in opposite directions to automatically pull out the steel bar, which is convenient for the automatic withdrawal of the steel bar after straightening.
