Abstract
The invention discloses a material pressing oil cylinder for a hydraulic plate shearing machine, which is provided with a cylinder body, wherein one end of the cylinder body is provided with a piston rod, the head end of the piston rod is connected with the head key of the material pressing oil cylinder, and particularly: the cylinder body is processed with a boss, a return spring is sleeved between the boss and the pressing cylinder head, the tail end of the piston rod is provided with two sealing rings, one end close to an oil pipe is provided with an inlet sealing ring, a sealing ring is further arranged at a position 5-10cm away from the inlet sealing ring and internally provided with an O-shaped sealing ring, one side of the outer side of the cylinder body close to the boss and the outer side of the pressing cylinder head are respectively processed with spring positioning rings, and two ends of the return spring are respectively fixed on the respective spring positioning rings; the invention solves the problem that the whole system has poor stability because the hydraulic control system of the existing hydraulic plate shearing machine is not provided with a material pressing oil cylinder, and the stability of the hydraulic system is greatly enhanced by using the material pressing oil cylinder, thereby avoiding production accidents such as oil pipe explosion and the like, and being suitable for wide popularization and application.
Description
Technical Field
The invention relates to the technical field of mechanical equipment, in particular to a material pressing oil cylinder for a hydraulic plate shearing machine.
Background
The hydraulic plate shearing machine applies shearing force to metal plates with various thicknesses by means of a movable upper blade and a fixed lower blade and adopting a reasonable blade gap, so that the plates are broken and separated according to required sizes. The existing power system of the hydraulic oil cylinder adopts a hydraulic control system, but has the following disadvantages: a material pressing oil cylinder is not arranged in a hydraulic control system of the conventional hydraulic plate shearing machine, and hydraulic oil is excessively buffered violently when being braked in a pipeline, so that great influence is brought to the stability of the whole system. Therefore, it is an urgent need to solve the above problems by improving the hydraulic system of the conventional hydraulic plate shearing machine.
Disclosure of Invention
The invention aims to provide a material pressing oil cylinder for a hydraulic plate shearing machine, aiming at the problem that the operation of a hydraulic system is unstable because the hydraulic system of the conventional hydraulic plate shearing machine is not provided with the material pressing oil cylinder.
The technical scheme of the invention is as follows: the utility model provides a hydraulic pressure trigger is with material hydro-cylinder of pressing for material hydro-cylinder, has the cylinder body, and the piston rod is equipped with to the one end of cylinder body, and the piston rod head end is connected with pressing the key-type of material cylinder head, especially: the cylinder body is processed with a boss, a return spring is sleeved between the boss and the pressing cylinder head, the tail end of the piston rod is provided with two sealing rings, one end close to an oil pipe is provided with an inlet sealing ring, a sealing ring is further arranged at a position 5-10cm away from the inlet sealing ring and is internally provided with an O-shaped sealing ring, one side of the outer side of the cylinder body close to the boss and the outer side of the pressing cylinder head are respectively processed with a spring positioning ring, and two ends of the return spring are respectively fixed on the respective spring positioning rings.
The top end of the material pressing cylinder head is also provided with a rubber buffer pad.
The hydraulic control system solves the problems that the hydraulic control system of the existing hydraulic plate shearing machine is not provided with a material pressing oil cylinder, the buffering of hydraulic oil is too violent during braking in a pipeline, and the stability of the whole system is greatly influenced.
