What Are The Production Steps Of Lawn Lights?

1. Cutting and cutting

1.1 Before cutting, first adjust the inclination of the cutting machine to match the required slitting ruler.

1.2 Determine the position of the steel plate to ensure the maximum size of the remaining material so that the remaining material can be used.

1.3 The length dimension is guaranteed by Kaiping, the wide bottom dimension is required to be ≤±2mm, and the tolerance of the blanking dimension of the high rod is to take the positive tolerance for the big end of the rod; general: 0-2m. Take the minus tolerance of the small head, after the -2-0mm size is adjusted, it is completed by the cutting machine and the automatic cutting machine.

1.4 Equipment: When cutting materials, check the operation of the rolling shear equipment, remove the debris on the track, and keep the equipment in good operating condition.

2. Bending. Bending is the most critical process in the production of light poles. The quality of the bending directly affects the quality of the light pole and cannot be repaired after bending. The specific attention is as follows:

2.1 Before bending: first remove the cutting slag of the sheet to ensure that there is no cutting slag crushing the mold during bending.

2.2 Check the length, width and straightness of the sheet. The straightness is less than or equal to 1/1000. If the straightness meets the requirements, correct it, especially the polygonal rod must ensure the straightness.

2.3 Increase the bending depth of the bending machine and determine the position of the sheet metal.

2.4 Mark the line correctly on the sheet, the error: ≤±1mm.

2.5 Correctly align the lines and bend correctly to minimize the pipe seam, and the height of the two sides should not be greater than 5mm.

3. Welding. Perform straight seam welding on the pipe seam after bending. Automatic submerged arc welding is used for welding, mainly because the welder should have more responsibility, and the welding position should be adjusted at any time during welding to ensure the straightness of the weld.

4. Repair and polish. Repair grinding is to repair the defects of the tube blank after automatic welding. The repairer should check one by one, and repair the defective place. After the repair welding is completed, the repair is carried out. The repaired joint is basically the same as the automatic weld.

5. Plastic surgery. The shaping process includes the straightening of the lamp pole and the round and polygonal diagonal dimensions of both ends of the billet pole. The general tolerance: <±2mm. The straightness error of the billet rod does not exceed: ≤±1.5/1000.

6. Let's go together. The flushing process is to smooth the two ends of the bent tube blank to ensure that the nozzle is perpendicular to the center line, and there is no angle and height unevenness. At the same time, after smoothing, the end surface is polished.

7. Install the bottom plate. For spot welding of bottom flange and ribs, the key is to ensure that the bottom flange is perpendicular to the straight center line of the lamp, the ribs are perpendicular to the bottom flange, and the straight line of the lamp is at the same time.

8. Weld bottom flange and ribs. The welding requirements refer to the welding process of the national standard to ensure the welding quality. The welding seam should be beautiful, free of pores and slag.

9. Open the door. In the working process of this process, you must be bold and careful (1) First, you must see the drawing to determine the direction of the door, and then locate it according to the size of the drawing. Dimensions include: up and down, left and right, and the size of the door frame. When plasma cutting, be careful to ensure that the slit is in a straight line. At the same time, the cut door panel and the light pole are marked with electric welding.

10. Welding door strips, electrical strips, and lock holders. When welding the door strip, the door strip with a width of 20mm should be extended by 8-10mm and put it down. Especially when spot welding, the door strip should be close to the light pole, and the welding should be firm. The welding device and the lock base are mainly located in accordance with the drawings. The lock base is welded in the middle of the door with an error of ≤±2mm. Keep the upper level and cannot exceed the light pole.

11. Bent the fork. The fork-bending process has the same properties as the door opening, so you should be bold and careful. First, pay attention to the direction of the door, second, pay attention to the starting point, the third angle of the light fork, the traction speed can not be fast or slow, and the yield rate is 100%.

12. Galvanized. The quality of galvanizing directly affects the quality of light poles. Galvanizing is required to be galvanized in accordance with national standards. After plating, the surface is smooth, without color difference, and there can be no sagging. Light poles with severe sagging must be re-plated.

13. Spray plastic. The purpose of plastic spraying is one for aesthetics and the other for corrosion prevention

13.1 Polishing: Use a polishing wheel to grind the surface of the galvanized pole to ensure that the surface of the pole is smooth and flat.

13.2 Straightening: straighten the polished light pole and shape the mouth shape, the light pole's non-straightness must reach 1/1000, caliber requirements: small pole ≤±1mm; high pole ≤±2mm.

13.3 Door plate

13.3.1 All door panels shall be processed after galvanizing, including zinc hanging, zinc leakage and zinc stored in keyholes.

13.3.2 When drilling the screw holes, the electric drill must be perpendicular to the door panel. The space around the door panel should wait until the door panel is level.

13.3.3 After the screws are fixed, the door panel cannot be loosened, and the fixing must be firm to prevent it from falling off during transportation.

13.3.4 Spray powder: Put the light pole with the door into the spray room, spray the color of the plastic powder according to the production plan, and then enter the drying room. The temperature and holding time of the drying room must be strictly in accordance with the requirements of each plastic powder to ensure Quality requirements such as adhesion and smoothness of plastic powder.

14. Factory inspection. The factory quality inspector conducts the factory inspection. The factory inspector must inspect the light pole inspection items one by one. The inspector must record and archive the items at the same time. The quality inspector can sign the product before delivery.

15. Wrap up and ship.

15.1 Bandaging: Bandaging according to customer needs

15.2 Before shipment, the warehouse will handle all the procedures before shipment in conjunction with the finance. The quantity, weight, and amount of the product shall be settled according to the contract. The goods can be shipped only after the financial account has issued the invoice, and the doorman can go out only with the exit card.

4. Flange and foundation embedded parts:

The flange is an important component for the lawn lamp and the ground installation. Lawn lamp installation method: Before installing the lawn lamp, it is necessary to weld the basic cage with M16 or M20 (common specifications) screws according to the standard flange size provided by the manufacturer. Then, at the installation site, dig a hole of appropriate size and The base cage is placed in it. After the level is corrected, cement concrete is used to fix the base cage. After 3-7 days, the cement concrete is fully solidified, and the lawn lamp can be installed. (Note: The pre-buried pipeline needs to be led out when the lawn lamp foundation is poured).
