When the width of the bottom of the metal plate to be processed changes, the adjusting gear 106 can be manually rotated, the adjusting gear 106 rotates to drive the two racks 104 to be close to or far away from each other, so that the two lower side plates 107 are close to or far away from each other, the positions of the lower left side roller 1011 and the lower right side roller 1012 which are inserted into each other are close to or far away from each other, the two upper side plates 300 at the upper end of the two lower side plates are driven to be close to or far away from each other through the connecting plate 307 while the two lower side plates 107 are close to or far away from each other, so that the positions of the upper left side roller 1001 and the upper right side roller 1002 which are inserted into each other are close to or far away from each other, and the widths of the upper press roller 100 and the lower press roller 101 are changed.
When the thickness of the processed metal sheet becomes thicker, the lower press roller assembly is not moved at this time, the adjusting screw 306 is rotated first to enable the two upper side plates 300 to slide towards the center, namely, the bus length of the upper press roller 100 formed by the upper left side roller 1001 and the upper right side roller 1002 is shortened, the distance between the two upper side rollers 403 and the two lower side rollers 408 is changed, then the adjusting screw 308 is adjusted to enable the connecting plate 307 to drive the upper side plates 300 to move upwards, even if the upper part of the device is wholly lifted, so that the cold pressing space between the upper press roller 100, the two upper side rollers 403, the lower press roller 101 and the two lower side rollers 408 is enlarged, and an adjusting effect is achieved.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
