Control points of automated sheet metal processing procedures

1. Number of punches

Control of the raw materials received in the warehouse before counting:

  • ①Whether the thickness of the raw materials used in various spare parts is consistent with the drawings, and the thickness tolerance of the raw materials is ±0.05mm;
  • ②Whether there are obvious black spots and corrosion spots on the surface of the raw materials used; whether the surface has obvious defects such as imprinting, scratching, deformation, etc. of the material itself (according to the different surface treatments of the products and the appearance quality requirements of different customers Depends);
  • ③Determine whether the raw materials are environmentally friendly according to different customer requirements;
  • ④ To make a product, the raw materials used for its parts and accessories must be the same brand and the same origin of raw materials. Avoid using two origins of raw materials for the same product to ensure the consistency of the product;
  • ⑤The same component of welding product is not allowed to use two different materials

2. Polishing

  • ① When rounding (right angle), the transition must be smooth, and the size of the chamfer must comply with the requirements of the drawing, and there must be no missing chamfers;
  • ②Knife marks must be cleaned and deburred, and the edges must not be jagged or beveled;
  • ③The acute angle must be blunt without any omissions;
  • ④Do not destroy the zinc layer on the surface of the product during grinding;
  • ⑤When the square hole is repaired, the marks and burrs must not be filed obliquely or the size of the square hole must not be too large;

3. Bending

  • ① The bending direction must be consistent with the drawing;
  • ②Bending dimensional tolerance control must meet the drawing requirements (note that the dimensional control during bending must take into account the spray margin, and the size of the part on the customer drawing is the size after surface treatment);
  • ③Control the bending angle, if there is no special requirement, the angle is generally controlled within ±1°;
  • ④Control of abnormal folding knife marks caused by bending;
  • ⑤After bending, the trial matching of the matching parts samples, whether the parts of the whole machine and the hole positions of the parts are aligned, whether the fit gap and the break are in line with the customer’s inspection standards;
