1. 1 Before cutting, adjust the inclination of the slitter to match the required longitudinal cutting ruler.

1.2 set the position of the steel plate, ensure the maximum size of the surplus material, and utilize the surplus material.

The length dimension of 1.3 is guaranteed by the opening time, the width dimension is ≤ 2mm, and the blanking dimension tolerance of high pole is positive at the big end of each pole; General: 0-2m. Take negative tolerance for small head, adjust the size of -2-0mm, and finish it with cutting and adjusting machine and automatic cutting machine.

1.4 equipment: during the shearing process, check the operation of the rolling shearing equipment, remove the sundries on the track, and keep the equipment in good operation.

Step 2 bend over. Bending is the most critical process in lamp pole production. The bending of the lamp post directly affects the quality and cannot be repaired after bending. Specific precautions are as follows:

2. 1 before bending: firstly, remove the slag from the sheet to ensure that the mold is not crushed by the slag during bending.

2.2 Check the length, width and straightness of the metal plate. Linearity ≤11000. If the straightness meets the requirements, correct it, especially for polygonal rods.

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

2.4 Correct marking with an error of ≤1mm..

2.5 Correct alignment, correct bending, minimize pipe joints, and at the same time, the height and bottom of both sides shall not exceed 5 mm.

3. welding. When welding, straight seam welding shall be carried out on the weld of elbow. Automatic submerged arc welding is mainly used because the welder should have more responsibilities and adjust the welding position at any time to ensure the flatness of the weld.

4. Repair and polishing. Grinding is to repair the defects of the tube blank after automatic welding. The repairman should check them one by one and repair the defective parts. After the repair welding is completed, it should be polished. The polished joints are basically the same as those welded automatically.

5. Plastic surgery. The forming process includes straightening the lamp pole, rounding the two ends of the blank pole and the size of the diagonal of the polygon. General tolerance:

6. Go hand in hand. The trimming process is to flatten both ends of the bent tube blank to ensure that the nozzle is perpendicular to the center line, and there is no uneven angle and height. At the same time, after flattening, the end face is polished.

7. Install the bottom plate. The key of spot welding between bottom flange and rib plate is to ensure that the bottom flange is perpendicular to the straight center line of the lamp, and the rib plate is perpendicular to the bottom flange and parallel to the straight bus of the lamp.

8. Weld the bottom flange and rib. Welding requirements refer to national welding technology to ensure welding quality. Weld should be beautiful, without air holes and slag inclusion.

Open the door. In this process, we must be bold and cautious (1). First of all, we should look at the drawings to determine the direction of the door, and then locate it according to the size of the drawings. Dimensions include: up, down, left and right, door frame size. When plasma cutting, be careful to ensure that the cutting seam is in a straight line. At the same time, the serial numbers of the cut door panels and lamp posts are burned by electric welding.

10. Weld the door lever, electric lever and lock seat. When welding door strips, the 20mm wide door strips should be placed at the position of 8- 10mm, especially when spot welding, the door strips should be close to the lamp post and welded firmly. The welding between the pole and the lock seat is mainly based on the drawings. The lock seat is welded in the middle of the door with an error of ≤ 2mm, and the top is kept horizontal and does not exceed the lamp post.

1 1. The fork bending process is the same as the door opening, so be bold and cautious. One is to pay attention to the direction of the door, and the other is to pay attention to the bending point and angle of the third optical fork. The traction speed can not be fast or slow, which really promotes the yield of 100%.

12. Galvanizing. Galvanizing directly affects the quality of lamp poles. Galvanizing shall be carried out in accordance with national standards. After electroplating, the surface is smooth without color difference, and there can be no sag. The severely drooping lamp post must be re-plated.

13. Plastic spraying. The purpose of plastic spraying is for beauty and anticorrosion.

13. 1 polishing: use polishing grinding wheel to smooth the surface of the galvanized lamp post, so as to ensure the smooth surface of the lamp post.

13.2 straightening: straighten the polished lamp post and shape the mouth. The straightness of light pole must reach11000, and the caliber requirements are: small column ≤1mm; High pole ≤ 2mm.

13.3 door panel

13.3. 1 Treat all door panels after galvanizing, including zinc hanging, zinc leakage and zinc storage in keyhole.

13.3.2 when drilling screw holes, the electric drill must be perpendicular to the door panel, and the gaps around the door panel should wait until the door panel is flat.

13.3.3 After the screws are fixed, the door panel must not be loose, and the fixation must be firm to prevent it from falling off during transportation.

13.3.4 plastic powder spraying: put the lamp post with the door installed in the plastic spraying room, spray the color of plastic powder according to the production plan, and then enter the drying room. The temperature and heat preservation time of the drying room must be strictly in accordance with the requirements of each plastic powder to ensure the quality requirements of plastic powder such as adhesion and smoothness.

14. Factory inspection. Factory inspectors carry out ex-factory inspection, and the ex-factory inspectors carry out item-by-item inspection according to the items of lamp post inspection. The inspector shall record and file at the same time, and the goods can be delivered only after the inspector signs it.

15. Bandage and delivery.

15. 1 bandage according to customer's requirements.

15.2 before delivery, the warehouse will go through all the formalities before delivery together with the finance department. The quantity, weight and amount of products are settled according to the contract, and the goods can only be delivered after the financial department issues an invoice, and the doorman can only go out with the exit card.

4. Flange and foundation embedded parts:

Flange is an important part of lawn lamp and ground installation. Installation method of lawn lamp: Before the lawn lamp is installed, it is necessary to weld the foundation cage with M 16 or M20 (general specification) screws according to the standard flange size provided by the manufacturer, then dig holes with appropriate size at the installation site, put the foundation cage into it, and after leveling, pour cement concrete to fix the foundation cage. After 3-7 days, the cement concrete is completely solidified, and the lawn lamp can be installed. (Note: The embedded pipeline needs to be led out when the lawn lamp foundation is poured).

Installation steps:

When installing lawn lamp, open the package, check the integrity of lawn lamp, and refer to the product manual for assembly and wiring. The general steps are as follows: open the lamp shell, install the light source and supporting electrical appliances (please refer to the electrical specification for electrical wiring), lead the lead-out wire from the threading hole to the bottom of the lamp post, then connect the lamp cap with the lamp post, pay attention to tighten the fastening screws, and then align the lawn lamp flange with the screws of the foundation embedded parts and stand vertically. Then, after leveling with nuts or washers, tighten the mounting nuts.

Lawn lamp circuit wiring:

After the lawn lamp is installed, it can be wired according to the instruction tree and the electrician's instructions. It should be noted that the installation wiring needs to be grounded, and generally lawn lamps will reserve grounding terminals for grounding to prevent potential safety hazards.
