1. The cutting shear

1.1 article first adjust the cutting machine in front of the shear Angle with the vertical scissors feet to operator.

1.2 set a plate put the position to ensure that the maximum size of the remaining material, make the remaining material to use.

1.3 length by open at ordinary times guarantee, under the wide bottom size requirements plus or minus 2 mm or less growing material size tolerance each section rod head is tolerance; As a general rule, be 0 to 2 m. Small head minus tolerance, - 2-0 mm size adjusted later, performed by cutting machine, automatic cutting machine.

1.4 equipment: cutting should check the running situation of rolling shear equipment, clear the debris on the track, keep equipment in good running condition.

2. Bend, bend is the key procedure in the production of light pole, the stand or fall of bending, directly affect the quality of the light pole and after bending forming beyond repair. Specific attention to the following:

2.1 before bending: first, to get rid of the sheet metal cutting slag, ensure no cutting slag crushed during bending mold.

2.2 check sheet of length, width and straight, not 1/1000 or less straight degree, if not straight degree requirements, revision, especially the polygon pole make sure is not straight.

2.3 the large bending machine bending depth, determine the plate put the position.

Error: 2.4 correct marking on sheet metal, plus or minus 1 mm or less.

2.5 right on the line, right bend, the pipe seam to minimize, two arms at the same time the high end is not more than 5 mm.

3. Welding. When welding the folded straight seam welded pipe seam after bending. For welding is semi-automatic welding, mainly welder should have more responsibility, should be adjust the position of welding, welding guarantee weld straightness.

4. Repair grinding. Repair after grinding is for automatic welding of tube billet defects repair. Repair personnel should be checked by the root, found defective parts to repair, repair welding is completed, and then to grinding, grinding it with automatic weld are basically the same.

5. Plastic. Plastic process including light pole straightening and two round the ends of the rod and polygon diagonal dimension, tolerance commonly: < plus or minus 2 mm. Billet stem straightness error is less than: + / - 1.5/1000 or less.

6. Keep up. Keep working procedure is bent into ponder on both ends of the tube billet, ensure the nozzle and the center line of the vertical, there is no Angle and height, at the same time make the after end surface polishing.

7. The base plate. Spot welding bottom flange and steel plate, the key is to ensure that the bottom flange to the light straight vertical centerline, vertical stiffened plate and bottom flange, and the lamp straight generatrix flat line at the same time.

8. Welding bottom flange and steel plate. Welding requirements with reference to the national standard of welding procedure, ensure the welding quality of welding seam to beautiful, porosity, slag.

9. Open the door. This process in the process of work, must be calibrated boldness, first to see the drawings to determine the direction of the door, and then according to the drawing size. Dimensions include: up and down, left and right sides, and the frame size, should be cautious when plasma cutting, guarantee, cut a straight line, at the same time cut the door plank with light pole distribution in welding to burn.

Article 10. Welding door, electric appliances, locks. Welding article door, the door is a 20 mm wide out 8 to 10 mm position down, especially when welding article door should be close to the light pole, welding to firm. Article welding electric appliances and lock, mainly according to the drawing order good location, welding in the middle of the door lock block, error of plus or minus 2 mm or less, keep the above level, no more than light pole.

11. The bending fork. Open fork bending process and have the same nature, should be calibrated boldness. First of all, pay attention to the direction of the door, the second note bending point, the third light fork Angle, traction cannot fast and slow, it promote the yield of 100%.

12. Galvanized. Galvanized quality directly affects the quality of the light pole, galvanized requirement according to national standards of galvanized, after plating surface is smooth, no color difference, there can be no sag, sagging serious light pole must be born again returned to the plating.

13. Plastic spraying. Coating is the purpose of it is in order to beautiful, 2 is for corrosion resistance

Grinding: 13.1 use galvanized surface polishing grinding wheel to grind, guarantee the light pole surface smooth, level off.

Straightening 13.2: after grinding the light pole of straightening and synchronized to plastic, light pole not must achieve 1/1000 straight degree, caliber requirement: small bar plus or minus 1 mm or less; Growing plus or minus 2 mm or less.

13.3 door plank

13.3.1 all door plank after galvanized processing, processing including zinc, zinc and zinc deposit in keyhole.

13.3.2 drill screw holes must drill and door, door plank of the clearance to around, door plank of repair.

After 13.3.3 screws, door plank can't loose, solid state must be strong in case of loss in transit.

13.3.4 plastic spraying powder: the light pole into the spray room door, according to production plan requires molding powder color plastic spraying, and then into the chamber, chamber temperature and holding time must be strictly in accordance with the requirements of various plastic powder to ensure the adhesion of plastic powder and finish quality requirements.

14. The factory inspection. By factory department inspector to factory inspection, the factory inspector must follow a light pole test project item by item, inspection, inspector must be record on file at the same time, the qualitative check member signature rear can deliver goods.

15. Dress, send the goods.

15.1 bandage bandage to meet the need of customers.

15.2 before shipment from the warehouse, jointly with the finance all formalities done before shipment. According to the contract for settlement for the product quantity, weight, amount, by financial behind the open invoices for shipment, the guard by shipper visitors to go out.
