Alternative hydraulic resonance device of block making machine

Abstract

The invention provides an alternative hydraulic resonance device of a block making machine, solving the problem that current vibration devices are unreasonable in structures. A vibrating body comprises a principal vibrating mass and an auxiliary vibrating mass; a master vibration spring is fixed between the principal vibrating mass and the auxiliary vibrating mass; a piston rod is connected with the principal vibrating mass; an alternative sleeve is internally provided with an impeller fixed on a rotating shaft; both sides of the impeller are provided with a high-pressure inducer and a low-pressure inducer; outer cylindrical surfaces of the high-pressure inducer and the low-pressure inducer are provided with circular grooves; circular grooves are provided with axial diversion trenches communicated with odd and even cavities enclosed by blades on the sides close to the impeller; the alternative sleeve is provided with an oil through with thickness less than that of the blade on the corresponding position of the blade; the alternative sleeve is also provided with high-pressure oil inlet hole and oil outlet hole on the corresponding position of the circular groove of the high-pressure inducer and is provided with an oil return hole on the corresponding position of the circular groove of the low-pressure inducer; a shell is provided with holes on the corresponding positions of holes of the alternative sleeve; the high-pressure oil outlet hole is communicated with an upper cavity or a lower cavity of an oil cylinder; the oil through is communicated with another cavity. The alternative hydraulic resonance device has the advantages of saving energy, having large amplitude and high frequency and being stepless and adjustable.

Description

technical field [0001] The invention relates to a matching device for a block forming machine, in particular to an AC hydraulic resonance device for a block forming machine. Background technique [0002] With people's increasing requirements for environmental protection, concrete blocks have become the main material of building walls, and concrete blocks are made by block forming machines. The block forming machine puts the dry hard concrete into the mold box, and the pressure head of the block forming machine exerts pressure and generates vibration through the machine table or the mold, and the dry hard concrete is formed by pressure vibration. The vibration device installed on the block forming machine includes a motor, an oil cylinder, a vibrating body and a converter. The oil cylinder includes a piston, a piston rod connected to the piston and a cylinder body. The piston divides the cylinder body into an upper chamber and a lower chamber. The piston in the oil cylinder ...
