Bending size of the mold, no unloading, uneven feeding, poor riveting

Bending size of the mold, no unloading, uneven feeding, poor riveting

Bending size of the mold, no unloading, uneven feeding, poor riveting

  1. Bending size

  2. a. The mold is not adjusted in place, resulting in angle error, which causes dimension deviation, poor closing height or poor angle difference
    b. Insufficient elasticity leads to poor angle, resulting in dimensional deviation Replace the spring
    c. The material does not meet the requirements, resulting in poor angle, which leads to size change or re adjustment of gap deviation
    d. Poor angle caused by material thickness deviation determines the material thickness due to size deviation. Replace the material or readjust the gap difference
    e. Size deviation caused by improper positioning Adjust the positioning to make the size OK
    f. Design or processing errors cause repair welding and grinding between the bending male parts, eliminate the gap between the parts, and lead to small bending size~
    g. There is no R angle for forming, and the bending height is too small under the angle and other normal conditions for forming the common R angle
    h. The bending size on both sides is too large
  3. Unstable size caused by unilateral bending and drawing, increase spring force, and adjust positioning

  4. j. Unreasonable clearance, resulting in poor angle and dimension deviation
    k. The height of the folding knife is not enough. The bending punch is too short to close the folding knife. The height of the folding knife is increased to make the bending punch close to the folding knife position as much as possible, causing more bad angles
    l. When bending, the speed is too fast, causing deformation at the bending root. Adjust the speed ratio and select a reasonable speed
    m. The structure is unreasonable, the folding knife is not inserted into the fixed template, and the groove is milled again. When the folding knife is inserted into the template for stamping, the gap becomes larger
    n. The hardness of the forming male during heat treatment is not enough, resulting in the collapse of the pressing line or the flattening of the reshaping male pressing line
  5. No unloading

  6. a. Improper positioning or feeding Adjust the positioning or feeding device
    b. Refuge position is not enough, repair and grind the avoidance position
    c. The inner guide pillar is strained, which causes the blocking movement to be impeded. Replace the inner guide pillar
    d. The punch is strained or the surface is not smooth Replace the punch
    e. Unreasonable layout of ejector pin Relocate the position of ejector pin
    f. The ejection force is not enough or the stripping force is not enough. Replace the ejection spring or stripping spring
    g. The punch and the splint don't fit smoothly. Repair the punch and the splint to make the punch fit smoothly
    h. The formed slider does not fit smoothly. Trim the slider and the guide groove to make them fit smoothly
  7. The stamping heat treatment is not suitable, and the deformation occurs after stamping for a period of time. Grind the stamping again, and correct the deformation

  8. j. The punch is too long or the length of the ejector pin is not enough. Increase the length of the ejector pin or replace it with a punch with a suitable length
    k. Punch break Replace the punch
    l. The template is not magnetized, and the workpiece is demagnetized upward to the template
  9. Unsmooth feeding

  10. a. The mold is not upright, resulting in the material belt not in the same line with the feeder and the mold to re frame the mold or adjust the feeder
    b. Uneven belt leveling machine or material replacement
    c. If the feeding is not smooth due to non unloading, refer to the non unloading solution

    d. Positioning is too tight Adjust positioning
    e. The guide pin is too tight or the straight wall position is too long Adjust the guide pin
    f. The punch is not fixed well or is too long to interfere with the strip. Replace the punch with a suitable length and fix it again
    g. The ejector pin is too short, and the strip interferes with the forming block. Adjust the length of the ejector pin to avoid interference
    h. Improper arrangement of floating block position Adjust floating block position
  11. Poor riveting

  12. a. The closing height of the die is improper. The riveting is not in place. Adjust the closing height
    b. The workpiece is not put in place, and the positioning deviation is adjusted for positioning
    c. Before riveting, confirm whether the riveting hole is chamfered by referring to the countermeasures for solving the defective workpiece. If there is no chamfer, increase the chamfer
    d. The riveting punch is not long enough. Replace it with a punch with proper length
    e. Confirm that the riveting punch does not meet the requirements and use the riveting punch that meets the requirements
