The General Production Process Of Stainless Water Bottle
May 14, 2021
The thermos cup is made of stainless steel pipe as the main raw material. The general production process flow chart:
1. Shell processing flow Outer pipe picking-pipe cutting-bulging-segmentation-bulging-rolling middle angle-shrinking bottom-cutting bottom-punching-flat upper mouth-flushing bottom-flat bottom mouth-cleaning and drying-inspection Knock the pit-qualified shell
2. Inner shell processing process (there are two, this process is a visual process. The other is stamping, but the limitations of stamping are large) Inner tube picking—cutting tube—flat tube—bulging—rolling corner— Flat top mouth—flat bottom mouth—thread rolling—cleaning and drying—checking and knocking—butt welding—testing water leak detection—drying—qualified inner tank
3. The assembly process of outer shell and inner shell with cup mouth—welding port—pressing midsole—welding bottom—welding port welding bottom—midsole spot welding getter—vacuum—temperature measurement—electrolysis—polishing—temperature measurement—inspection Polishing—Pressing the outsole—painting—pumping temperature detection—inspecting paint—screen printing—packing—finished product storage
Brief description of production process
1. Pipe cutting: Use a lathe to execute the "Tube Cutting Operation Guide". Accurate dimensions are required, defective products and waste materials are found in time, and pits, pits, pits, and scraps should be avoided during operation.
2. Water swelling: The water swelling press is specifically implemented in accordance with the "Water swelling operation guide". It requires concentration and always pay attention to whether the pit, size, and shape of the product meet the requirements.
3. Segmentation: Use an instrument car to cut off the two outer shells of the water swelling one and the other. The dimensions are required to be accurate, the cuts are uniform, no gaps, and burrs. Handle with care to avoid pits, pits, pits, and scrap Product.
4. Bulging: Use a large press, which can be executed in accordance with the "Water Expansion Operation Guide". Attention is required. The pipe weld of the shell should correspond to the joint of the mold. Always pay attention to the pit and size of the product. , Whether the shape meets the requirements.
5. Rolling angle: Use a lathe to roll the two corners that pass through the concave shape of the bulging shell to meet the size requirements to avoid pits, pits, pits, and scraps.
6. Bottom reduction: Use a lathe, and follow the "Retraction Operation Guide". Reduce the arc bottom of the bulging shell to meet the size requirements to avoid pits, pits, pits, and scraps.
7. Cut the bottom: Use a lathe to cut the bottom of the shell that has been shrunk to a standard size, with even cuts, no gaps, and burrs, and handle it gently to avoid pits, pits, pits, and scraps.
8. Reinforcement: flatten the welding seam at the shell mouth on a small press, so that there will be no skip welding during welding, so that the welding joint is smooth and even.
9. The shell is flat and top: Use a lathe to make the flat and even, without notches, and burrs, meet the requirements, handle with care, and avoid pits, pits, pits, and scraps.
10. Bottom punching: Use a press to pay attention, always pay attention to whether the pit, size, and shape of the product meet the requirements, and pay special attention to whether there are cracks at the bottom of the punching.
11. Flat-bottomed mouth: Use an instrument car. The flat-bottom mouth is even, without notches and burrs, and meets the requirements. Handle with care to avoid pits, pits, pits, and scraps.
1 2. Flat tube: Use an instrument car to flatten one end of the tube mouth. The flat mouth is even, without gaps and burrs, and meets the requirements; handle with care to avoid pits, pits, pits, and scraps.
1 3. Roll up the corners: Use a lathe to roll the bulging corners of the bulged liner to meet the size requirements, handle with care and avoid pits, pits, pits, and scraps.
14. The inner tank is flat and top mouth: Use an instrument car to have a uniform flat mouth, no gaps, and rough edges, which meet the requirements; handle with care to avoid pits, pits, pits, and scraps.
15. Thread rolling: Use a special threading machine, according to the "Thread Rolling Operation Guide". Attention is required to adjust the thread depth to meet the size requirements; handle gently to avoid pits, pits, pits, and pits. Scrap.
16. Washing and drying: Clean and dry the inner tank and outer shell; handle with care to avoid pits, pits, pits, and scraps.
17. Check 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, handle them gently.
18. Butt welding: butt welding the inner tank and the inner bottom according to the "Butt Welding Operation Guide". The welding seam is required to be smooth, free of loopholes and no pits.
19. Water test and leak detection: Inflate the butt-welded inner tank to test the water, and if there are any leaks in the weld, it is qualified.
20. Matching cup mouth: Put the inner tank and outer shell together, and the cup mouth is flat; handle gently to avoid pits, pits, pits, and scraps.
21. Bottom of Welding Joint: It is specifically implemented in accordance with the "Working Instructions for Welding Bottom of Welding Joint". It is required to ensure that the bottom of the welded joint is penetrated and smooth, without bumps, bumps, and missing solder joints.
22. Spot welding: Spot welding on the inside of the midsole with getter. Note that the getter on spot welding must be vacuumed within 24 hours to achieve a good effect, otherwise it will be invalid.
23. Press the midsole: Press the welded cup onto the midsole that is spot welded on the getter, and press it evenly with the bottom.
24. Inspect the bottom of the welded joint: inspect the cup with the well-welded bottom, and pick out whether there are missing welds, poor cup welds or other bad reasons.
25. Vacuum: Vacuum without tail, strictly in accordance with the vacuum operation standard.
26. Temperature measurement: According to the "Electrical Temperature Measurement Process Operation Guide", check whether the cup is vacuum, and pick out the non-vacuum cup.
27. Electrolysis: The electrolysis in the cup is required to be evenly bright, without watermark or yellow dots.
28. Polishing: The cup shell is required to be polished finely and with orderly lines, the cup mouth is smooth and bright, and there must be no obvious wire drawing, scratches, black threads and pits, and polishing paste residues.
29. Inspect polishing: whether the polished cup meets the requirements. If it is not good, it must be polished again. If it is good, it will flow to the next process.
30. Press the outsole: Press the outsole on the polished cup, and it is required to be flattened.
31. Paint spraying: send the spray paint to an outsourcing company, the color is the same, the spray paint is required to be even and firm, and there should be no paint drop, pitting, etc.
31. Inspect the spray paint: Check whether the painted cup meets the spray paint requirements. If it is not good, it must be repainted and polished. If it is good, it will flow to the next process.
32. Silk screen: The logo should be clearly printed on the silk screen as required. The logo, size, color, and position should be as clear as the sample; the silk screen label cannot be stuck in a plastic bag, and it is not easy to buckle it with nails, so it must be baked in a drying tunnel after the silk screen.
34. Packaging
