The guiding and sliding horizontal shaft 43 slides at the bottom of the corresponding second fixed seat 42, improving the stability of the horizontal movement of the material supporting mechanism 3.

[0038] Working principle: During use, the auxiliary material supporting device and the bending machine are installed. The auxiliary material supporting device is installed at the rear end of the bending machine, so that the position of the folding pressing knife of the folding machine and the position of the turning horizontal shaft 22 are vertically corresponding, and the turning horizontal shaft 22 is directly below the position of the folding pressing knife; The rear end of the plate is passed through the folding pressing knife of the folding machine. At this time, the plate is placed on multiple third balls 241 and first balls 512 for rolling support. According to the end of the plate, the telescopic cylinder 46 is controlled to be opened, and the third fixed seat 44 is driven to control the horizontal movement of the material supporting mechanism 3, adjusting the horizontal positions of multiple longitudinal sliding cylinders 52 on the material supporting mechanism 3, so that the side end of the longitudinal sliding cylinder 52 at the initial end position contacts the end of the plate for limit material blocking; Subsequently, the folding pressing knife is controlled to press down to bend the rear end of the plate; After the plate is bent for a certain distance, many bent parts appear at the rear end of the plate, and the length of the rear end of the plate increases. Subsequently, when the plate is continuously bent, by controlling the horizontal movement of the material supporting mechanism 3 and adjusting the horizontal positions of multiple longitudinal sliding cylinders 52 on the material supporting mechanism 3, the side end of the longitudinal sliding cylinder 52 at the end position contacts the end of the plate for limit material blocking of the plate; Subsequently, the second motors 542 at the positions of multiple longitudinal sliding cylinders 52 are controlled to start, driving the first shaft 541 and the first gear 54 to rotate. Since the first gear 54 is meshed and connected with the rack 53, the longitudinal sliding cylinder 52 is driven to lift and slide in the material supporting cross bar 51, flexibly adjusting the height position of the second ball 55 until the second ball 55 contacts the lower surface of each part of the plate for effective and comprehensive support. Subsequently, the third motor 583 on the longitudinal sliding cylinder 52 at the end position is controlled to drive the second shaft 582 and the second gear 581 to rotate. Since the second gear 581 is meshed and connected with the rack 53, the sliding sleeve frame 58 is driven to lift and slide outside the longitudinal sliding cylinder 52, flexibly adjusting the height position of the positioning ejector rod 59 so that the bottom end of the positioning ejector rod 59 contacts the upper surface of the end of the plate, positioning the end of the plate and improving the stability of subsequent plate bending. Subsequently, the folding pressing knife is controlled to press down again to bend the rear end of the plate. At the same time, the first motor 253 is controlled to start, driving the transmission worm 251 to drive the transmission worm wheel 25 to rotate, thereby controlling the turning horizontal shaft 22, the L-shaped bracket 23 and the third connecting cross frame 26 to rotate around the turning horizontal shaft 22, and thus controlling the material supporting mechanism 3 to rotate around the turning horizontal shaft 22 to assist in supporting the plate to turn, preventing the plate from vibrating when the length of the rear end of the plate is long during bending. Due to the provision of multiple longitudinal sliding cylinders 52, it can adapt to the auxiliary material blocking and auxiliary material supporting turning of end plates with different lengths, and can also adapt to the comprehensive auxiliary support material blocking and material supporting turning of end plates with different bending forms, improving the flexibility and use effect of the entire device.
