    Standard tolerances for precision high-speed punch stamping parts

    When precision high-speed punching machines carry out die stamping, the matching dimensional tolerance of the parts is generally selected according to the following standards:

    1. Standard push parts such as guide bushes and positioning pins are required to have tolerance fits, and they are generally mass-produced, and their fit size tolerances are selected according to fixed requirements.

    2. The matching dimensional tolerances of standard parts in "matching" processing are generally selected according to standard parameters.

    3. Tolerances should be consistent with mold processing standards and technical levels.

    The height of the surface roughness of precision high-speed punch mold parts has a great impact on the fit accuracy of the mold parts, the wear resistance and fatigue strength of the mold parts. We should select economical, usable, and excellent mold materials based on relevant factors such as high-speed punch mold working standards, mold manufacturing standards, and basic properties of mold materials.

    The basic properties of die materials, from the mold working standards of precision high-speed punch machines, generally stipulate that die materials must have basic properties such as good wear resistance, ductility, strength and compressive strength.

    Precision high-speed punch stamping parts must be based on the specific working conditions of different molds, and each must meet its specific requirements for other properties. For example, for molds working under high loads, characteristics such as compressive strength, tensile strength, bending strength, fatigue strength and cracking toughness should also be considered. The process performance of the die material and the process performance of the mold material are one of the very important factors that affect the cost of the mold. A mold with good process performance can not only simplify the mold production process and facilitate manufacturing, but also reduce the manufacturing cost of precision high-speed punch molds.
