Hydraulic blank cutting machine

Abstract

The invention provides a hydraulic blank cutting machine belonging to the technical field of brick making mechanical equipment. A hydraulic device is used for replacing a crank connecting rod mechanism of the prior blank cutting machine, and is provided with a power element, a control element and two hydraulic cylinders which synchronously work; the hydraulic cylinders are installed on a stand ofthe blank cutting machine, are in rigid connection with the stand, and are connected with the control element and an oil tank through pipelines; a piston rod of each hydraulic cylinder is connected with a pushing head of the blank cutting machine; an accumulator is arranged on the pipeline between the hydraulic cylinder and the oil tank; an oil absorption pipeline and an oil return pipeline are both provided with filters; the power element of the hydraulic device is a gear pump; and the control element comprises a check valve, an overflow valve, a one-way throttle valve, an electromagnetic directional valve and a ball valve. The invention has the advantages of reasonable design, simple structure, energy-saving system, higher synchronous accuracy, convenient control and safe use.

Description

technical field [0001] The invention relates to a hydraulic blank cutting machine, which belongs to the technical field of brick making machinery and equipment. Background technique [0002] In the brick and tile production line, the blank cutting machine is an indispensable auxiliary equipment. Most of the conventional blank cutting machines use a crank-link mechanism, that is, a motor drives the connecting rod after being decelerated by a cycloid reducer to realize the reciprocating motion of the push rod, and then cut the mud strips. But there are various disadvantages in this kind of organization. For example: (1) It is not easy to achieve separation and control: (2) The billet cutting machine works periodically, and the waste of electric energy is large: (3) The power of the equipped motor is large (4) The vibration of the whole machine system is large, unstable, and the components are easily damaged or loose. (5) Parts require detailed calculation and precise proces...
