Rotating reversing valve, building block forming machine rotating hydraulic vibration platform and method

Abstract

The invention provides a rotating reversing valve, a building block forming machine rotating hydraulic vibration platform and a method. Based on a valve body and a valve element which are matched witheach other, the valve element can rotate in the valve body; the upper end portion and the lower end portion of the portion, located in the valve body, of the valve element are each provided with a bearing; a hollow valve cavity is formed in the valve body; bearing groove positions are arranged in the positions, corresponding to the bearings, at the inner edge of the valve cavity; different oil ports are formed in different positions of the inner edge of the valve cavity; the valve element is provided with a plurality of oil ways; by controlling the rotating position of the valve element relative to the valve body, the relationship between the different oil ways and the oil ports is changed, the oil liquid flow direction is changed, transmission of oil liquid in the different oil ports isachieved, continuous reversing can be performed many times in one rotating period, and the vibration frequency is greatly improved.

Description

technical field [0001] The disclosure relates to a rotary reversing valve, a rotary hydraulic vibration platform of a block forming machine and a method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Vibration is a common physical phenomenon. The reciprocating motion of an object near the equilibrium position is vibration. Vibration is widely used in industry. Using vibration can easily complete many processes and improve production efficiency. According to statistics, there are many types of vibrating machinery. Less than a few hundred types, typical such as high-frequency hydraulic vibrators, vibration crushers, hydraulic impact drills, vibration testing machines, etc. There are good applications, and vibration is also one of the applications in the process of block forming. Vibrators used in industry can be divided into mechanical,...

AI Technical Summary

Problems solved by technology

Vibrators used in industry can be divided into mechanical, electric and hydraulic; due to their own limitations, mechanical and electric vibrators are difficult to meet today's increasingly high requirements for excitation frequency and output force, while traditional hydraulic vibrators The vibrator is mostly controlled by a servo valve, and its performance will also be limited by the frequency response characteristics of the servo valve itself.
