AI Technical Summary
In the prior art, the conical contact of the wedge block assembly becomes point contact, which leads to a reduction in contact area, damage to the lubricating oil film, severe surface damage, attenuation of the pin clamping force, and possible wedge displacement, resulting in uneven force distribution.
Design a full-line contact wedge assembly for ejector pins, including a pin, a stop, a flat wedge, and a guide sleeve. By uniformly distributing the flat wedges and fitting them against the pin, line contact is achieved, increasing the contact area, improving lubrication, and ensuring uniform force on the wedges.
It improves the load-bearing capacity of the wedge, reduces friction, improves wear, extends service life, ensures uniform wedge distribution and force distribution, and reduces errors.
