AI Technical Summary
During the processing of cemented carbide parts, the cemented carbide parts with smaller support surfaces at the bottom lack a fixed structure due to the lack of a fixed structure on the lower template, which leads to the skewed carbide, and the forces on both sides are uneven, making it difficult to effectively press.
A cemented carbide processing press is designed. By setting a fixing groove on the lower formwork and installing a fixed structure in the fixing groove, including a fixing plate, a threaded rod and a clamping plate, the cemented carbide parts can be clamped and fixed to avoid uneven stress.
This design effectively avoids the skew problem caused by uneven stress during the processing process of cemented carbide parts. It is especially suitable for processing scenarios where cemented carbide workpieces are pressed on one-sidedly, improving the stability and efficiency of processing.
