7.W11S-30X2000 Plate Rolling Machine Technical Features<?
A drum-shaped upper roller is used, and the preset amount of the upper drum drum is generally preset at 70% of the uniform roller load. The lower roller has a smaller diameter, and the lower roller has an adjustable upper roller support. According to the load of the rolled product, the idler roller at the lower part of the lower roller is adjusted, and the straightness of the product is greatly improved.A. Rolling plate conditionsB. Rolling sheet situation
The upper roll universal bending machine adopts rear bending (the direction in which the sheet is fed is opposite to the direction in which the upper roll moves), the upper roll presses down, the lower roll rotates, continuously bending, and the end of the sheet is pre-bent and pressurizes the pre-bend directly. This avoids the front corners from being bent, and controls the length and shape of the remaining straight edges.In general, the three-roll asymmetric type adopts the front curve. The two ends of the sheet are pre-bent, and then symmetrically rolled to form. The skilled operator is required. The back corner of the product appears, and the shape of the remaining straight edge is difficult to control.A, W11S-30X2000 Plate Rolling MachineB, three-roller asymmetrical type (the level adjustment of the upper roller, the level adjustment of the lower roller, the downward adjustment of the arc, the four-roller bending machine, etc.)A.The top roller presses down and the bottom roller rotatesB.The end of the sheet is first pre-bent and then rolled symmetrically.A.The end of the plate, using direct pressure pre-bendingB.The lower roller is reversed, first pre-bent, then rolled
A.The product does not have a back corner, and the ends of the remaining straight edges are controlled on the standard round and the roundness of the product is high.
B.There is a back corner in the product, it is more difficult to control the end of the remaining straight edge on the standard circle, and the roundness of the product is not high.
7-3 Reduce the amount of misprints
1 The center-to-center dimensional accuracy of the two lower rollers and the two lower rollers, as well as the shape and position tolerance, are taken as key process control;2 Synchronous electro-hydraulic combination of the upper roll, using feedback system, automatic leveling.Displacement sensor detection, the pre-amplifier signal amplification of the upper roller cylinder, the comparison of the control machine, high and low level to the programmable controller, control the electromagnetic reversing valve solenoid on both ends of the roller, continuous feedback comparison, synchronous precision control Within ±0.15mm range.
7-4 High Precision End Prebend
When the end is pre-bent, the length of the straight edge can be freely set by changing the amount of horizontal movement of the upper roller; the upper roller is directly pressurized to control the shape of the straight edge, and high-precision end pre-bending can be realized.
7-5 Operation Procedure and Method
1: feed the plate, the material;2: the upper roller moves horizontally to the -X position and descends to the Y1 position; the lower roller is reversed to make the steel plate to the forming position.3: the next roller side is rotating, the side of the roller press;4: The upper roller is pressed down to the Y2 position and the lower roller is continuously rotated forward;5: The end of the plate is stopped, the upper roller presses Y3 to stop, and the end of the plate is directly pressurized and pre-bent;6: The upper roller lifts Y2-α, horizontally moves the +X position, presses the same position Y2, and the lower roller rotates forward;7: The end of the plate is stopped, the upper roll presses down and the Y3 position stops, and the end of the plate is directly pressurized and pre-bent;8: The upper roller moves to X=0 and is pressed down to the Y4 position, and the lower roller is rotated forward and backward to compensate bending.
