[0019] In the embodiment of the utility model, the adjustment of the material rack part:

[0020] Correct placement of the plate on the material rack: the front edge of the plate is tightly attached to the material blocking plate 107 of the rounding machine rack, the inner side is tightly attached to the fixed blocking rod 103 and the right separating rod 105, and then the plate is lightly tapped with a rubber hammer to make each plate tightly attached to the inner blocking rod. The outer left separating slide 106 and the tail separating seat 113 are moved away or pulled outwards when the plate is placed. After the plate is leveled, it is adsorbed on the edge of the plate. The plate is placed on the 100mm plate pad 102 below. The plate pad 102 should be smaller than the length and width of the plate. The plate pad 102 made separately is slotted at the point of the suction cup position, so that the suction cup vacuum is broken when the plate is used up. Generally, the fixed iron sheet is transported by the external vacuum suction head.

[0021] Adjustment of the height of the material rack: the material level sensor 104 is a device for controlling the height of the plate. If the height is adjusted too high, the plate is easily double-zoned. If the height is adjusted too low, the plate is not stably adsorbed. The height can be controlled by adjusting the screw on the material level sensor 104. The cylinder on the adsorption part 108 is extended to the limit position, so that the suction cup has a compression amount of 2-3mm and is adsorbed on the plate plane.

[0022] Maintenance of the transmission of the material rack: the box body of the elevator 111 and the lubricated screw rod with the oil storage cylinder 112 need to be regularly added with appropriate butter to lubricate the copper turbine. The oil inlet 25 is led out on the outside of the rack to facilitate the user to add lubricating oil.

[0023] In the embodiment of the utility model, the adjustment of the rounding curvature and the rounding pressure;

[0024] Adjustment of the rounding curvature: the curvature adjustment is achieved by the up-down swing of the rounding pressure shaft 1. When adjusting, the curvature block screw 22 and the locking screw 20 on the curvature block 2 are loosened. The hand wheel 19 is rotated upwards to swing upwards. The rounding curvature is larger, the diameter of the workpiece is larger, and vice versa. The rounding curvature is smaller, the diameter of the workpiece is smaller, and the locking screw is tightened after the adjustment is completed.

[0025] Adjustment of the rounding pressure: the pressure adjusting screw 5 is rotated downwards. The rounding pressure is larger, and vice versa. When adjusting, please pay attention to adjusting both sides at the same time, so that the pressure on both sides remains consistent. Attention: if the spring pressure is too large, the plate will be crushed. If the pressure is too small, the plate feeding will be unstable and cause slipping.

[0026] Adjustment of the gap of the rounding shaft 6: the gap between the upper and lower shafts is adjusted to be between 0.2-0.4mm. According to the thickness of the plate, the gap is appropriately adjusted without crushing the plate and causing the plate feeding to slip. The adjustment method is as follows: the two gap adjusting screws 4 and the nuts are completely loosened, so that there is no gap between the upper and lower shafts. Then the two gap adjusting screws 4 are first contacted to the top block without causing a gap between the upper and lower shafts. The gap adjusting screws 4 are sequentially inserted with the inside hexagonal wrench at the correct angle. The clockwise is twisted. One turn is 1.25m. The gap is adjusted according to the thickness of the plate. The screw nut is tightened after the adjustment is completed.

[0027] Adjustment of feeding shaft 14: Feeding shaft 14 is the first stage shaft that feeds the plate to be sucked up, and each end of the shaft above the pre-bending shaft 13 has a spring, which is used to adjust the balance of the plate pressure when the spiral-shaped tank body after being rounded into a circle, so that the tank body is in a regular cylindrical shape.

[0028] Adjustment of pre-rounding knife 15: Loosen the pre-rounding knife adjusting screw 16, and the pre-rounding knife 15 can swing up and down. In actual use, the T3 hardness plate is adjusted upward, and the plate above T4 hardness is adjusted downward. If the material is thin and soft, the adjustment is slightly upward, and the pre-bending is too large. The plate is easy to fold inward when it is sent to the ironing shaft. If the material is thick and hard, the adjustment is downward, and the pre-bending is also adjusted downward, so that the plate is more easy to bend. If the pre-bending is too small, the plate is easy to fold upward when it is sent to the round pressing shaft 1.

[0029] Adjustment of ironing shaft: The gap between the upper ironing shaft 9 and the lower ironing shaft 10 is 2-4mm. If the plate is too hard or exceeds 0.35mm, the gap between the upper and lower ironing shafts should be as small as possible without blocking the plate.

[0030] Exclusion of double sheets: When there are double sheets in the double sheet detection 11, the equipment will automatically stop, or the plate will be stuck in the machine head and cannot come out. Loosen the two locking handwheels 27 on the upper machine head and lift it up. Lift it up until the spring latch 26 automatically pops into the positioning hole to safely remove the double sheets or the stuck plate. When there are double sheets, you can also press the round reverse button on the side of the machine head to remove the plate.

[0031] The horn shape of the rounded tank cylinder: The non-parallelism between the round pressing shaft 1 and the round shaft 6 can cause the horn shape of the tank cylinder. To adjust the up and down position of the arc block, loosen the arc block screw 22 at the large end of the tank cylinder, move the adjusting gear 3 away from the gear position of the arc block, and move the arc block 2 downward by one tooth or more until the rounded cylinder is free of horn shape.

[0032] Working principle: The adsorbed sheet is sent to the feeding shaft 14 by the cylinder. The misalignment between the feeding shaft 14 and the pre-bending shaft 13 makes the front end of the sheet pre-bend. After pre-bending, the front end of the sheet has a tendency to bend inward, and it is sent to the round shaft 6 to make it round. The small guide roller between the feeding shaft 14 and the round shaft 6 is the ironing roller, which functions to eliminate the elastic stress generated during rolling and pressing, so that the sheet is sent to the round device in a plastic state.

[0033] The round pressing shaft 1 adjusts the position of the round pressing shaft 1 to make the sheet round to the required size of the round cylinder, and then sends it into the groove of the transition guide rail in a vertical hanging state, and the outer side is supported by the retaining support.

[0034] The rounded part is equipped with a double sheet detection 11. After the sheet is pushed out by the adsorption cylinder, it is detected by the double sheet detection 11. When two or more sheets pass through, the main machine stops urgently.

[0035] The embodiments of the present application disclose the preferred embodiments, but are not limited to the same, and the ordinary skilled in the art can easily understand the spirit of the present application according to the above-mentioned embodiments, and make different inferences and changes, as long as the spirit of the present application is not deviated, which are within the protection scope of the present application.
