Pin placement: The locating pin and the detecting pin shall be clamped in the corresponding spring clip on the measuring tool body after use in inspection: In assembly drawings, there must be a clear statement of pin and hole.
Background:
In the stamping production of progressive stamping die, it is necessary to carry out specific analysis for the phenomenon of poor stamping, adopt effective treatment measures, and fundamentally solve the problems that occur, so as to reduce production costs and achieve smooth production.
The following is the reason for the common bad stamping phenomenon in production and treatment measures are as follows, for the tool maintenance personnel to refer.
The progressive stamping punching edge
Cause:
1) The cutting edge wear
2) The gap is too large to repair the cutting edge after the effect is not obvious
3) The cutting edge collapse angle
4) The gap is unreasonable up and down offset or loose, up and down dislocation.
Countermeasure:
a. Grinding the cutting edge.
b. Control the precision of the convex and concave die machining or modify the design gap.
c. Grind the cutting edge.
d. Adjust the punching clearance to confirm the problem of the hole wear of the template hole or the processing precision of the molded part.
e. Replace the guide or remodeling.
In the measurement process of stamped parts, locating pins (or locating pin components) are typically used to ensure accurate and stable positioning of the stamped part during measurement or processing. Their main role is to ensure that the stamped part is properly aligned in the measuring fixture or gauge, enabling precise dimension measurement, inspection, or further processing.
Functions and Roles of Locating Pins:
Precise Positioning: Locating pins match with corresponding holes or other fixed points on the stamped part to ensure that the part stays in place during measurement, preventing measurement errors caused by vibration or positional shifts.
Increased Efficiency: The use of locating pins reduces the time spent on adjusting the part during the measurement or processing stage, thus improving production efficiency.
Error Reduction: Locating pins help ensure consistency in measurements, reducing errors caused by human operation and ensuring the accuracy of the measurement results.
Stability: Locating pins provide stable support, especially for larger or more complex stamped parts, preventing even minor displacement of the part.
Common Types of Locating Pins:
Cylindrical Locating Pins: Suitable for stamped parts with larger hole diameters, simple in design, and easy to position quickly.
Flat Locating Pins: Primarily used for precise positioning on flat surfaces, commonly seen in simpler gauges or fixtures.
Multi-stage Locating Pins: These have multiple sections of different diameters to accommodate a variety of stamped part sizes, used for more complex part positioning.
Design Considerations for Locating Pins:
Material Selection: Locating pins are typically made of high-strength steel or alloys to ensure durability and stability, preventing wear or deformation.
Surface Treatment: To improve wear resistance and reduce friction, locating pins may undergo hardening or coating treatments.
Tolerance Requirements: The dimensional tolerance of locating pins is usually quite strict to ensure a precise fit with the corresponding holes in the stamped parts for stable positioning.
Positioning and Quantity: When designing gauges, the number and placement of locating pins are determined based on the shape and measurement needs of the stamped part, ensuring the part is firmly and consistently positioned in the fixture.
Applications:
Locating pins are widely used in the measurement gauges and fixtures of stamped parts, especially in industries such as automotive, home appliances, and electronics, where high-precision requirements are critical in the production process.
If you have specific measurement fixture or stamped part application requirements, feel free to provide more details, and I can assist you further in optimizing the selection or design of locating pins.
