Abstract

The invention provides a power head system of an electro-hydraulic hammer. The power head system of the electro-hydraulic hammer comprises a main cylinder seat, a main cylinder, an energy accumulator cylinder and a strike valve, wherein the main cylinder, the energy accumulator cylinder and the strike valve are arranged on the main cylinder seat, the parts, arranged in the main cylinder seat, of the main cylinder, the energy accumulator cylinder and the strike valve are connected through an internal pipeline, and the bottom of the main cylinder is connected to a hammer rod; an oil discharging valve and a buffering valve are installed in the internal pipeline of the main cylinder seat; an operation valve is arranged on the upper portion of the strike valve and connected with the oil discharging valve and the strike valve through the internal pipeline and controls shut-off and connection of the oil discharging valve and the strike valve. The power head system of the electro-hydraulic hammer operates the electro-hydraulic hammer in a fully hydraulic mode, a power head and an oil tank are arranged separately, and the electro-hydraulic hammer is cleaner in use process and prevents pollution of oil liquid through pipeline connection. In addition, the operation system is simple, power is provided for the electro-hydraulic hammer through the power head, and the power head system of the electro-hydraulic hammer has the advantages of being high in strike force and strike speed and the like.

Description

technical field [0001] The invention relates to the field of electro-hydraulic hammers, in particular to an electro-hydraulic hammer power head system. Background technique [0002] Forging hammer occupies a large proportion in forging equipment and is the most widely used one, of which steam-air free forging hammer accounts for more than 70%. Existing steam air forging hammers use steam or compressed air as the power source. It has the disadvantages of high energy consumption (energy utilization rate is only about 1%), and it needs to build expensive power stations, such as steam stations, etc., and it has serious environmental pollution and poor working conditions, which is very different from the current development of forging technology. adapt. [0003] Full-hydraulic electro-hydraulic hammer is a new type of energy-saving and environmentally friendly forging equipment. There are single-arm electro-hydraulic hammer, double-arm electro-hydraulic hammer and bridge-type e...
