The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, utilize plate bending rolls to make the method for tread, it comprises the steps:
1) blanking: according to the design size of required step plate with steel plate line, cutting stock, the steel billet of must marking time;
The industrial premises steel structure stairway mostly is a checkered steel plate, and there is antiskid particles in the checkered steel plate front, and bad line is in order to guarantee the accuracy of blank size, the general method that adopts in the line blanking of the checkered steel plate back side; Semi auto cutting machine is adopted in the blanking cutting, and material cutting back will be removed totally the oxide that adheres on the cutting edge; Dimensional errors required after blanking was finished: appearance and size deviation≤2mm, diagonal deviation≤3mm.
2) making of loose tool tool: the loose tool tool is made up of first supporting steel plate 1, second supporting steel plate 2, the 3rd supporting steel plate 3, second supporting steel plate 2, the 3rd supporting steel plate 3 lay respectively at first supporting steel plate 1 above, leaving a bending groove 4, the second supporting steel plates 2, the 3rd supporting steel plate 3 between second supporting steel plate 2 and the 3rd supporting steel plate 3 welds with first supporting steel plate 1 respectively;
The thickness H1 of first supporting steel plate 1 determines: the thickness of slab of H1＞2 times plate bending rolls rated capacity;
The thickness H2 of second supporting steel plate 2 determines: H2=h, h are the flanging thickness of step plate;
The thickness H3 of the 3rd supporting steel plate 3 determines: H3=h-δ, h are the flanging thickness of step plate, and δ is the thickness of step plate;
The width L3 of the 3rd supporting steel plate 3 determines: L3=L+100mm, L are the width of required step plate;
The width L2 of second supporting steel plate 2 determines: L2=R+200mm, R are the last diameter of cylinder of plate bending rolls;
The width L1 of first supporting steel plate 1 determines: L1=0.5 * R+0.5 * L+L0+500mm, R are the last diameter of cylinder of plate bending rolls, and L is the width of required step plate, and L0 is the center to center distance of the bottom right cylinder of the bottom left cylinder of plate bending rolls and plate bending rolls;
The width r of bending groove (gap of second supporting steel plate 2 and the 3rd supporting steel plate 3) determines: r=δ+2mm, δ are the thickness of required step plate;
The length of first supporting steel plate 1, second supporting steel plate 2, the 3rd supporting steel plate 3 is the length of 1 ~ 4 times of step plate;
The location dimension a=0.5 of the 3rd supporting steel plate 3 * L+0.5 * L0+200mm;
About the making of fetal membrane, sometimes do not have the lucky steel plate of thickness at the scene, can with electric welding machine the steel plate spot welding of stack be got up again with the needed thickness of sheet pack addition of different-thickness.
3) go up tire: elder generation is with the last cylinder rising (to certain position) of plate bending rolls, then the insertion of loose tool tool is gone up between cylinder 6 and bottom left cylinder 7, the bottom right cylinder 8 (the loose tool tool need not be fixed), the length direction of loose tool tool and last cylinder (bottom left cylinder, bottom right cylinder) is set level row; The last cylinder of plate bending rolls is descended, compress the loose tool tool;
Utilize that cylinder compresses the loose tool tool on the plate bending rolls.This step will be paid special attention to, and is a process that needs are debugged repeatedly.When cylinder on the plate bending rolls begins to contact with the loose tool tool, plate bending rolls is applied to the downward pressure of loose tool tool needs piecemeal increase, every increase by one point pressure just needs the operation plate bending rolls to seesaw by the loose tool tool, sees frictional force between plate bending rolls and the loose tool tool steel billet of whether can bending marking time; If once add very big pressure, just damage plate bending rolls easily.
4) roll-forming: an end of the steel billet of will marking time is put into the bending groove 4 of loose tool tool, after the steel billet of marking time is put well, start plate bending rolls, the last cylinder of plate bending rolls, bottom left cylinder, the rotation of bottom right cylinder drive loose tool tool horizontal direction and seesaw, in this process, bending in will the mark time end of steel billet of pressure on the plate bending rolls between cylinder and loose tool tool, forms a flanging of step plate, takes out from bending groove 4 rolling over the steel billet of marking time on one side; The other end that to roll over the steel billet of marking time is on one side more put into the bending groove 4 of loose tool tool, and a flanging of having rolled over is (making the finished product after the press-bending is the zigzag shape) up, repeats above-mentioned roll-forming process, forms another flanging of step plate, step plate.
Marking time to roll needs two people to cooperate, the one man operation plate bending rolls, and the people steel billet of marking time of blanking puts into the bending groove 4 of loose tool tool.After the steel billet of marking time was put well, the operator operates plate bending rolls seesawed the loose tool tool, and in this process, the pressure on the plate bending rolls between cylinder and loose tool tool bends steel plate.Note the flanging direction, make the finished product after the press-bending is the zigzag shape.
Labour's tissue:
This worker's method needs 1 riveter and 1 burner to cooperate.The blanking stage, riveter line, burner's cutting; In the process segment, riveter operates plate bending rolls, burner's feeding, discharging.
The quality installation administration:
1, quality requirement: the line of stair step, blanking are wanted accurately.Loose tool tool placement location is correct, and length direction is parallel with cylinder.
2, safety management: it is clean if cutting edge is jagged after the blanking of marking time, must to remove, polish, otherwise when the feeding of marking time, discharging, has the danger that hand is scratched.In the process of rolling of marking time, plate bending rolls operator and material loading person cooperate tacit, and the operator could operate after necessarily waiting material loading person both hands to leave plate bending rolls.
