A two-way synchronous vibration pressure vibration brick press

Abstract

A bisynchronous press-vibration brick machine achieves feeding through synchronous hydraulic cylinders which are connected in series. When materials are fed to a certain position reaches a position, a servo motor starts operating, and an end face cam is used for enabling an output plunger to move up and down in a reciprocating mode. Due to the fact that the plunger located at the front end of the output shaft is inserted in a rodless cavity of the upper hydraulic cylinder and can move up and down, the size of the rodless cavity changes, pressure fluctuation is generated in an oil line, finally an upper piston and a lower piston output excitation force which fluctuates periodically, and bisynchronous press-vibration forming is achieved. The bisynchronous press-vibration brick machine compacts and forms powder through bisynchronous vibration, transfer of forming force is facilitated, and the compactness and uniformity of products are improved. Bisynchronous excitement is achieved through the oil cylinders which are connected in series, the structure is simple, and the the brick machine is easy to obtain. The upper hydraulic cylinder and the lower hydraulic cylinder are connected through a communication pipe, vibration phases maintain synchronous, and vibration synchronization can be guaranteed without other devices.

Description

technical field [0001] The invention belongs to the technical field of brick-making equipment, and in particular relates to a two-way synchronous vibration-pressure vibratory brick press. Background technique [0002] At present, pressed unburned bricks are mainly produced by introducing foreign equipment. Foreign advanced brick presses can not only achieve greater pressing force but also adjust the vibration frequency according to the type of raw materials. However, the equipment independently produced in my country can only produce small batches and low-strength bricks, which is technically backward compared with foreign countries. The brick press is easy to adjust the vibration frequency, but the pressing force is small. The hydraulic brick press can produce a large pressing force, but it is difficult to adjust the frequency through the vibration generated by the hydraulic system, and it cannot be applied to a variety of raw materials. Studies have shown that in the proce...
