Copper bar manufacturers: copper bar processing process requirements
15
Copper row processing technology requirements 1. The calculation before copper row blanking makes full use of the Pythagorean theorem. 2. Pay attention to adding or subtracting the thickness of the copper row in the calculation before processing the copper row to reduce the manufacturing error. 3. When calculating the copper bar, pay attention to whether the measuring tape starts from 100mm, and the error of 100mm should be subtracted from the calculation.. 4. Before unloading the copper row, consider whether there is any waste row that can be used. 5. Wear gloves when processing copper bars to prevent oxidation of the copper bars. 6. When processing copper bars, ensure that the surface is smooth, free of scratches, flat, wrinkles, inclusions, and deformation and distortion.. 7. There must be no burrs on the cut surface and punching surface of the copper bar. 8. The square used for drawing lines of copper bars should be close to the copper bars. 9. The diameter of the holes shall not be greater than 1/2 of the width of the copper bar, and the processing shall ensure that the position is correct, vertical, and not skewed, and the error of the mutual distance between the holes shall not be greater than 0.5mm. Requirements for copper row processing personnel: 1. The production personnel must undergo copper row processing training. 2. The production staff must have strong logical thinking ability (need to have certain talent conditions). 3. The production staff must have a certain amount of physical strength. 4. The production staff must be able to bear hardships and stand hard work. Preparations before copper bar processing: 1. On-site production requires grinding wheel cutting machine, hydraulic bending machine, solder bar, solder paste, cotton cloth, angle grinder, flat file, emery cloth, tape measure, square, drawing needle and heating copper bar Heating equipment (cutting gun or blowtorch), etc.. 2. The workshop production requires sawing machine, punching machine, bending machine, mold, tape measure, square ruler, drawing needle, cotton cloth, etc.. 3. Check the quality of the copper bars. The surface of the copper bars should be smooth and flat, and there should be no cracks, wrinkles, inclusions, deformation and distortion. The copper bars should be straightened and the cut surface should be flat.. Copper bar processing flow: preparation-calculation and measurement-marking-punching (drilling on site)-bending-hanging tin [shop outsourcing tin plating]-installation. Movement and storage during the processing of the copper bars: 1. The movement of the copper bars should be carried out in one piece. If stacking prevention is required, isolation measures (using air cushion film or felt) should be taken to ensure that the surface of the copper bars is smooth and smooth, and handle with care.. 2. The contact surface of the copper row must be a wooden or rubber shelf. 3. Wear clean gloves when handling copper bars to prevent corrosion on the surface of the copper bars caused by sweat traces. 4. The copper bars are not allowed to directly touch the ground during the collection and production process. 5. The copper busbars should be clearly marked before delivery to facilitate on-site installation. Bending requirements for copper bar processing: 1. The bending angle of the copper bar shall not be less than 90°.After forming, there should be no cracks or wrinkles in the bend, and the unevenness is no more than 1mm. 2. Rectangular copper bars should be cold-bent, not hot-bent. 3. The copper bars should be bent at right angles to be reduced, and there should be no cracks and significant wrinkles at the bends; the bends of multiple bus bars should be consistent. 4. When the copper bar is twisted by 90°, the length of the twisted part should be 2 of the width of the bus bar.5-5 times. The busbar bending type should be bent as required. There are three basic bending types as follows, the bending type and the most bending radius: a. Flat bend b. Vertical bend c. The length of the torsion part should not be less than 2 of the width of the busbar when the busbar is twisted at 90° in a flat-twisted bend.5~5 times, Yueqing Renhe Electronics Co., Ltd. is a professional copper bar manufacturer in Zhejiang, focusing on new energy electric vehicle battery copper bar connection, electrical connection copper bar, braided copper bar, flexible copper bar connection, cable connection and insulation Production, development and sales of protective sleeves.Products comply with EU environmental protection, UL flame retardant, ISO9001 management system certification requirements.
