Brief description of production process 1. Pipe cutting: use a lathe, specifically according to the “Pipe Cutting Operation Instructions”, the size is required to be accurate, and defective products and wastes should be found in time, which should be avoided during operation. Generate pits, pits, pits, and scrap.
2. Water swelling: The water swelling press is implemented in accordance with the “Water swelling operation instructions”, requiring attention to be concentrated, and always pay attention to whether the pit, size and shape of the product meet the requirements.
3. Segmentation: Use an instrument truck to cut off the two outer shells that are swollen by water. The size is required to be accurate, the cut is uniform, no gaps, and burrs. Handle with care to avoid pits, pits, pits, and scrap. Taste.
4. Bulging: use a large press, which can be carried out according to the “Water Swelling Operation Instructions”, requiring attention to be concentrated. It is that the welding part of the tube of the shell should correspond to the joint of the mold, and always pay attention to the pit and size of the product. , Whether the shape meets the requirements.
5. Rolling the middle corner: Use a lathe to roll the two corners of the concave shape of the bulging shell to meet the size requirements, and avoid pits, pits, pits, and scrap.
6. Shrinking the bottom: Use a lathe, and implement it according to the “Shrinking Operation Instructions”. Reduce the arc bottom opening of the bulging shell to meet the size requirements to avoid pits, pits, pits, and scrap.
7. Bottom cutting: Use a lathe to cut the bottom of the shell that has been shrunk to a standard size. The cutting is uniform, without gaps and burrs. Handle it gently to avoid pits, pits, pits, and scrap.
8. Rib punching: Flatten the welding seam at the mouth of the shell on a small press, so that the welding seam will not be skipped during welding, so that the welding seam will be smooth and even.
9. Flat cover of the shell: use a lathe, the flat mouth is even, without gaps, burrs, meet the requirements, handle with care to avoid pits, pits, pits, and scrapped products.
10. Bottom punching: When using a press, focus attention is required. Always pay attention to whether the pits, size and shape of the product meet the requirements. In particular, pay attention to whether there are cracks at the bottom of the stamping.
11. Flat-bottomed mouth: Use the instrument car, the flat-bottomed mouth is uniform, without gaps, burrs, and meets the requirements. Handle with care to avoid pits, pits, pits, and scrapped products.
12. Flat tube: use the instrument car, flatten one end of the tube, the flat mouth is even, without gaps, burrs, and meets the requirements; handle with care to avoid pits, pits, pits, and scrapped products.
13. Roll the upper corner: Use a lathe to roll the protruding corner of the bulged liner until it meets the size requirements, and handle it with care to avoid pits, pits, pits, and scrap.
14. The inner liner is flat-topped: use the instrument car, the flat-mouth is uniform, without gaps, burrs, and meets the requirements; handle with care to avoid pits, pits, pits, and scrapped products.
15. Thread rolling: Use a special thread machine, specifically according to the “Thread Rolling Operation Instructions”, require attention, adjust the depth of the thread to meet the size requirements; handle with care to avoid pits, pits, pits, and scrap. Taste.
16. Cleaning and drying: Clean and dry the inner tank and outer shell; handle with care to avoid pits, pits, pits, and scrapped products.
17. Inspection of knocking pits: Check whether the inner tank and outer shell are qualified. If there are pits and pits, knock them flat to meet the requirements, and handle with care.
18. Butt welding: Butt-weld the inner tank and the inner bottom, according to the “Butt Welding Operation Instructions”, which requires the welded seam to be smooth, free of loopholes and no pits.
19. Water testing and leak detection: Inflate the butt-welded inner tank to test the water to see if there are any loopholes in the butt-welded seam, and no leakage is qualified.
20. Matching the mouth of the cup: put the inner tank and the outer shell together, and the mouth of the cup is flat; handle it with care to avoid pits, pits, pits, and scrapped products.
21. Welding bottom welding: It is specifically implemented in accordance with the “Welding Bottom Welding Process Operation Instructions”, which requires to ensure that the bottom of the welding joint is penetrated and smooth, and there are no bumps, welding bumps and missing solder joints.
22. Spot welding: Spot welding on the getter in the midsole. Note that the getter on the spot welding must be evacuated within 24 hours to achieve a good effect, otherwise it will be ineffective.
23. Press the midsole: Press the cup with the welded mouth on the midsole of the spot-welded getter, and press it flat with the bottom mouth.
24. Inspection of the bottom of the welding mouth: Inspect the cup with the bottom of the welded mouth, and pick out whether there is any leakage of welding, poor welding of the mouth of the cup or other bad reasons.
25. Vacuuming: no tail vacuuming, strictly in accordance with the vacuuming operation standards.
26. Temperature measurement: according to the “Electrical Temperature Measurement Process Operation Instructions”, check whether the cup is vacuum, and pick out the non-vacuum cup.
27. Electrolysis: To send out electrolysis, the electrolysis in the cup is required to be bright and uniform, without watermarks and yellow spots.
28. Polishing: It is required that the shell of the cup is polished finely and the lines are orderly, the mouth of the cup is smooth and bright, and there should be no obvious drawing, scratches, black wires and pits, and polishing paste residues.
29. Inspection and polishing: whether the polished cup meets the requirements, the bad ones should be re-thrown, and the good ones will flow to the next process.
30. Press the outsole: Press the outsole on the polished cup, and it is required to be flat.
31. Spray paint: send out spray paint, the color is the same, the spray paint is required to be uniform and firm, and there should be no paint drop, pitting, etc.
32. Inspection of spray painting: Check whether the painted cup meets the painting requirements. If it is not good, it needs to be repainted and polished. If it is good, it will flow to the next process.
33. Silk screen printing: According to the requirements, the logo of the trademark should be screen-printed clearly. The logo, size, color, and position of the logo should be like the sample. The screen-printed logo cannot be glued down with a plastic bag, and it is not easy to buckle it with a fingernail. Therefore, it must be baked in a drying tunnel after screen printing.
