Abstract

The invention discloses a braking and low-speed feeding energy-saving device of a forge rolling machine, and the braking and low-speed feeding energy-saving device can recycle rotation kinetic energy of a middle shaft during braking of the forge rolling machine for being stored, and can apply the stored energy to low-speed feeding of the forge rolling machine, so that energy saving is realized. The braking and low-speed feeding energy-saving device of the forge rolling machine comprises the middle shaft of the forge rolling machine, and further comprises a hydraulic motor, an energy-accumulation hydraulic control system and a hydraulic accumulator, wherein the hydraulic motor is in transmission connection to the middle shaft; the hydraulic accumulator has hydraulic oil therein; and the hydraulic motor can enable the rotation kinetic energy of the middle shaft of the forge rolling machine to be mutually converted with pressure potential energy of the hydraulic oil in the hydraulic accumulator via the energy-accumulation hydraulic control system, or the middle shaft drives the hydraulic motor to follow up. By adopting the braking and low-speed feeding energy-saving device of the forge rolling machine, energy resources can be saved, the processing cost and the maintain cost of equipment can be reduced, and the production efficiency of the forge rolling machine is improved.

Description

technical field [0001] The invention relates to a brake device for a roll forging machine, in particular to a brake and slow feed energy-saving device for a roll forging machine. Background technique [0002] Known: the braking device of the existing roll forging machine applied on the hot forging forging production line of heavy machinery industry is a friction brake (generally including two kinds of floating type and insert type), and its working principle is The friction torque generated by the friction of the moving disc is used to brake. On the one hand, the braking energy of this braking method generates heat volatilization, which not only causes energy waste, but also has adverse effects on the surrounding environment (noise, temperature, dust, etc.), and also causes wear and tear on the friction plates, requiring on-site maintenance workers to The amount of wear is adjusted regularly, and new friction plates must be replaced after the friction reaches a certain leve...
