[CN 201910147181.3] Hydraulic press for wheel hub forming
[CN 201910147181.3] A hydraulic press for hub forming Title: A hydraulic press for hub forming Application Number: CN 201910147181.3 Applicant: Henan University of Science and Technology Application Date: 2019-2-27 Patent Type: Invention Application The present invention relates to a hydraulic press for hub forming. The hydraulic press for hub forming includes a frame and a clamping pressing mechanism, and the clamping pressing mechanism includes a holder and a connector, at least two sets of symmetrically arranged elbow-bending linkage mechanisms are arranged between the holder and the connector. The elbow-bending linkage mechanism includes a second elbow rod, a first elbow rod hinged on the holder, and a connecting rod hinged on the connector. The clamping pressure mechanism also includes a swing limit structure that ensures that there is a certain angle between the first elbow rod and the connecting rod without being straightened, the toggle linkage mechanism also includes a toggle lever limit structure that keeps the second toggle lever in the outward inclined initial position before the mold is closed; the second toggle lever has a matching structure, and the frame is located on the outside of the second toggle lever A sliding hole is provided, and the second toggle rod is matched with the sliding hole after sliding into the sliding hole, and swings around the top position to support the holder to realize mold closing and pressurization. The clamping pressure mechanism and the sliding hole can be separated, so that the hydraulic press has a larger mold opening space.
