Forging machine with plunger type cylinder unbalance loading resistant structures and assembling and using method thereof

Abstract

The invention discloses a forging machine with plunger type cylinder unbalance loading resistant structures. The forging machine with the plunger type unbalance loading resistant structures comprises a main rack, an upper fixed beam, a prestress draw bar, a movable cross beam, a plunger type cylinder, a guide device and a movable workbench, and is characterized in that the plunger in the plunger type cylinder is fixed on the upper fixed cross beam through a T-shaped draw bar in a hanging mode, and unbalance loading resistance structures with spherical surfaces contacted with each other and shifting relatively are arranged between the upper end of the upper fixed beam and the tail end of the T-shaped draw bar and between the bottom portion of the plunger and the T-shaped head of the T-shaped draw bar. The forging machine with the plunger type cylinder unbalance loading resistance structures has the advantages that when a main cylinder bears unbalance loading force, the two unbalance loading structures with the spherical surfaces contacted with each other and shifting relatively can eliminate the unbalance loading acting on the cylinder body of the plunger type cylinder, the plunger of the plunger type cylinder is enabled not to be blocked, the service life of the plunger is prolonged, a seal is protected, the service lives of the seal and a copper sleeve are prolonged, the unbalance loading capacity of the plunger type cylinder is enhanced, and working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of forging presses, and in particular relates to a forging press with a plunger cylinder anti-eccentric load structure, an assembly method and a use method thereof. Background technique [0002] The forging press is a forging machine used for forming and separating in forging processed products, and transmitting working pressure with high-pressure liquid (oil, emulsion, etc.). The forging press works smoothly, without vibration, and can easily reach a large forging depth. It is most suitable for forging of large forgings and deep drawing, packing and briquetting of large-sized sheets. At present, the plunger of the known forging press passes through the upper fixed beam and is fixed on the upper fixed beam with bolts. The cylinder body is fixed on the movable beam with a pressure plate. For sealing, press the copper sleeve and seal on the cylinder body with a pressure ring, and the whole structure is rigidl...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the defects in the background technology that the plunger is in plane contact with the upper fixed beam, the eccentric load cannot be transferred, the combined seal life between the cylinder body and the plunger is low, and oil leakage occurs during use, the present invention provides a Forging press for plunger cylinder with contact and relative displacement anti-eccentric load structure and its assembly method and use method
