The production process of light pole can be divided into the following steps:
(1) cutting → (2) Bending → (3) welding → (4) repair grinding → (5) Plastic → (6) Qi head → (7) mounted floor → (8) welding floor → (9) to open the door → (10) Electric welding gate strip bar (bottom lock → (11) bent fork → (12) galvanized → (13) spray → (14) of the total seizure → (15) delivery
Second, each step to French:
1. Cutting
1.1 First cut before cutting adjust the inclination of the machine with the required vertical scissors ruler wanted character.
1.2 will be a good plate placement to ensure that the maximum size of more than expected, so I can use the material.
1.3 length dimension usually guaranteed by the open, wide bottom size requirements ≤ ± 2mm high pole material dimensional tolerance of each section take positive pole bulk of tolerance; general: 0-2m. Head negate tolerance, -2-0mm size adjusted after adjusting the cutting machine, automatic cutting machine to complete.
1.4 equipment: a material should check the rolling shear equipment operation, removing debris on the track, kept in good operating condition of the device.
2. Bend
Pole bending is a production of the most critical step, bending will directly affect the quality of the poles and after bending forming beyond repair. Specific attention to the following
Before bending 2.1: First remove the sheet metal cutting slag, crushed slag to ensure that no cut when bending mold.
Length, width and straightness 2.2 Check sheet metal, non-straightness ≤1 / 1000, if not meet the requirements of straightness, correction, especially polygonal rod must ensure straightness.
2.3 transfer large bending machine bending depth to determine the placement of the sheet.
2.4 correctly a line on the sheet, the error: ≤ ± 1mm.
2.5 on the right line, the right bend, the tube joints to a minimum, while the bottom two high side of not more than 5mm.
3. Welding
Welding seam on the tube after bending be straight seam welding. Due to welding is a semi-automatic welding, mainly due more accountability welder, welding should be ready to adjust the welding position, ensure that the weld straightness.
4. Patch polished
Is the repair sanding tube automatic welding defect after repair. Repair personnel should check by the root, we found to be defective places up after the completion of welding, then grinding, grinding and automatic welding pick at substantially the same.
5. Shaping
Shaping processes include straightening poles and two knockout punch of a full circle and polygon diagonal size, general tolerance: <± 2mm. Preform rod straightness error does not exceed: ≤ ± 1.5 / 1000.
6. Block process
Block process is the first step of the tube ends bent Shuhei ensure nozzle perpendicular to the centerline, the angle and height of injustice does not exist, but after Shuhei, were polished end face.
7. Replace the bottom
Spot welding the bottom flange and ribs, the key is to ensure that the bottom flange of the lamp straight vertical center line, and the bottom flange vertical ribs, while the bus and light flat straight line.
8. welded bottom flange and ribs
Welding requires reference to national standards of welding technology, ensure welding quality welding seam to be beautiful, no pores, slag.
9. open
This step in the course of their work must be bold but cautious
(1) first to see the drawing to determine the direction of the door, according to the paper size and orientation. Dimensions include: up and down, left and right, and the door frame size, plasma cutting to be cautious and ensure slotted straight line, and cut off the door with the number of poles with welded burning words.
10. Welding door strips, electrical strips, lock seat
When welding door door strip 20mm wide strips, extended 8-10mm position down, especially when spot-door bar should be close to the poles, welding to firmly. Electric welding bar and lock seat, mainly in accordance with the drawings set a good location, in the middle of the door lock seat welding, error ≤ ± 2mm, to maintain the level above, no more than the poles.
11. The curved fork
Curved fork process and the door has the same nature, should be bold but cautious. First, note the direction of the door
