Special free-forging hydraulic unit and use method thereof

Abstract

The invention relates to a special free forging hydraulic unit and a use method thereof. The special free forging hydraulic unit comprises a mechanical device of a main forging machine, a mechanical device of an assistant system, a hydraulic drive system for the main machine and the assistant system, and an electric automatic control device, wherein the mechanical device of the main forging machine comprises a main sealing frame, a work oil cylinder, a forging anvil mechanical assembly and a return cylinder mechanical assembly; and the mechanical device of the assistant system comprises a forging mechanical manipulator, a forging mechanical manipulator, a manipulator walk under carriage, a guide rail, a feeding roller way, a feeding manipulator, a discharging roller way, a discharging manipulator and an automatic centering mechanism. The special free forging hydraulic unit can adopt a hybrid operation mode combining a manual mode and a full automatic mode, not only can satisfy the requirement of product production and achieve production efficiency higher than a general free forging hydraulic press, but also effectively reduces investment cost of the devices.

Description

technical field [0001] The invention relates to a special complete set of equipment suitable for the production of small and medium-sized metal thermal processing shaft forging products, in particular to a special free forging hydraulic unit including a forging main engine directly driven by hydraulic pressure and auxiliary systems of electromechanical and hydraulic transmission and how to use it. Background technique [0002] At present, the production of small and medium-sized metal thermal processing shaft forging products usually uses steam-air dual-purpose free forging hammer, air hammer, electro-hydraulic hammer, free forging hydraulic press, fast free forging hydraulic press, precision forging machine-mechanical or hydraulic style. [0003] Steam-air dual-purpose free forging hammer, air hammer, and electro-hydraulic hammer have large vibration during production and low product dimensional accuracy; free forging hydraulic presses and rapid free forging hydraulic pres...

AI Technical Summary

Problems solved by technology

[0003] Steam-air dual-purpose free forging hammer, air hammer, and electro-hydraulic hammer have large vibration during production and low product dimensional accuracy; free forging hydraulic presses and rapid free forging hydraulic presses are general free forging equipment, if used for professional production of shafts that do not require upsetting technology Forging products, the production capacity of the equipment cannot be utilized, which relatively increases the production cost; although mechanical or hydraulic precision forging machines are suitable for the production of shaft forgings, the equipment investment is very large

[0004] It can be seen that the above-mentioned existing forging equipment obviously still has inconvenience and defects in structure, method and use, and needs to be further improved urgently.

In order to solve the problems existing in the existing forging equipment, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and there is no suitable structure for general products to solve the above problems. This is obviously a problem that relevant industry players are eager to solve
