The using method of the invention is as follows:
before the flat worm plate is required to be rounded into the worm-shaped worm plate, the position of the support sheet 21 can be roughly adjusted according to the width of the flat worm plate, so that the position of the support sheet 21 is adjacent to the clamping groove positions at two sides of the flat worm plate, when the position of the support sheet 21 is required to be roughly adjusted, the first linear slide block 13 can be directly slid, the first linear slide block 13 drives the first cylinder mounting seat 16 to stably move along the track of the first guide rail 4, at the moment, the support sheet 21 moves along with the first linear slide block, when the support sheet 21 moves to the actually required position, a screw can be screwed into the locking screw hole 15 on the locking block 14, so that the screw is tightly pressed on the first guide rail 4, the locking effect of the locking block 14 is realized, at the moment, the position of the first linear slide block 13 is fixed, the position of the first cylinder 17 arranged on the first cylinder mounting seat 16 is fixed along with the position, and the rough position of the support sheet 21 is fixed, then, the position of the supporting piece 21 can be finely adjusted by using the first cylinder 17, when the first cylinder 17 is started, the piston rod of the first cylinder 17 can drive the sliding piece 20 to move along the track of the sliding groove 19 on the upper surface of the sliding groove fixing block 18, the supporting piece 21 arranged at the rear end of the sliding piece 20 moves along with the sliding groove, when the supporting pieces 21 on the left side and the right side are just positioned at the clamping groove positions where the supporting pieces can be clamped into the two sides of the straight worm plate, the first cylinder 17 stops running, and the final position of the supporting piece 21 is fixed.
When the flat spiral plate needs to be rounded into a spiral plate, the first motor 35 can be started, when the first motor 35 operates, the motor shaft of the first motor 35 drives the first driving sprocket 36 to rotate, at this time, the first driving sprocket 36 drives the first driven sprocket 33 to rotate through the first chain, when the first driven sprocket 33 rotates, the lower roller shaft 31 rotates, and the driving gear 39 at the right part of the lower roller shaft 31 is meshed with the driven gear 40 at the right part of the upper roller shaft 28, so when the lower roller shaft 31 rotates clockwise, the upper roller shaft 28 rotates counterclockwise, when the flat spiral plate is located between the upper roller shaft 28 and the lower roller shaft 31, the rotating force of the upper roller shaft 28 and the rotating force of the lower roller shaft 31 both drive the flat spiral plate to be stably conveyed backwards, in order to ensure that the distance between the upper roller shaft 28 and the lower roller shaft 31 can adapt to the thickness of the flat spiral plate, the height of the upper roller shaft 28 can be adjusted through the second cylinder 23, and when the second cylinder 23 is started, the piston rod of the second cylinder 23 drives the upper bearing seat 27 to stably move up and down along the track of the adjusting groove 26, so that the distance between the upper roller shaft 28 and the lower roller shaft 31 is changed.
When the rounding operation is started, the front end of the flat and straight worm plate sequentially passes through the positions above the roller carrier shaft 10, the gap between the upper roller shaft 28 and the lower roller shaft 31 and the position above the movable roller shaft 55, at the moment, the lower surface of the flat and straight worm plate is contacted with the upper surface of the roller carrier shaft 10, the upper surface of the lower roller shaft 31 and the upper surface of the movable roller shaft 55, the supporting sheets 21 are positioned in the clamping grooves at the left side and the right side of the flat and straight worm plate, along with the synchronous rotation of the upper roller shaft 28 and the lower roller shaft 31, the flat and straight worm plate can be synchronously conveyed backwards when being rolled by the middle wheel 30 on the upper roller shaft 28, the side rollers 38 at the left side and the right side of the upper roller shaft 28 can effectively play a role in assisting the rolling, the yielding ring 37 is arranged at one side of the side roller 38 adjacent to the supporting sheets 21, the outer diameter of the yielding ring 37 is smaller than that of the side roller, the position of the yielding ring 37 corresponds to the position of the clamping, therefore, the situation that the clamping grooves on the side edges of the worm plates deform due to the fact that the side rollers 38 roll the side edges of the worm plates is avoided, the rolling position requirements of the middle wheel 30 and the side rollers 38 are different due to different sizes of the worm plates, the positions of the middle wheel 30 and the side rollers 38 can be adjusted according to actual needs, in order to adjust the positions of the middle wheel 30 and the side rollers 38, adjusting screw holes communicated with the inner spaces of the middle wheel 30 and the side rollers 38 can be formed in the outer walls of the middle wheel 30 and the side rollers 38, adjusting screws abutting against the outer wall of the upper roller shaft 28 are screwed in the adjusting screw holes, the positions of the middle wheel 30 and the side rollers can be adjusted only by loosening the adjusting screws, the adjusting screws are screwed again abutting against the outer wall of the upper roller shaft 28, and the middle wheel 30 and the side rollers 38 after the position adjustment can be fixed.
