Embodiment 1

[0049] combine figure 1 , a double-pump shearing machine system, comprising a tool rest 14, an oil pump motor 1, a main oil pump 2, an oil tank 3, a main oil cylinder 13, an auxiliary oil cylinder 15, a pressing oil cylinder 16 and a pressure switch 17, on the said knife rest 14 An inclination sensor 18 is provided, which is connected to an external control system 19 . The inclination sensor 18 of this program is used for the level measurement of the system. The inclination sensor 18 can be divided into three kinds of inclination sensors of "solid pendulum" type, "liquid pendulum" type and "gas pendulum" from the working principle. The inclination sensor 18 can also be used to measure the change in inclination relative to the horizontal plane. The inclination sensor 18 of this program is arranged on the top surface of the knife rest 14, and the top surface of the knife rest 14 is a horizontal surface, and the center of the top surface is set;

Embodiment 3

[0076] Claim 3 is basically the same as claim 1, the difference lies in the control method;

[0077] A control method for a double-pump shearing machine, the steps are as follows:

[0078] (A) start the plate shearing machine system, start the plate shearing machine system, and the control system 19 starts to receive the inclination angle information of the inclination sensor 18, the main oil pump 2 and the pressure information of the pressure material oil pump 4;

[0079] (B) By receiving the oil pump information, the main oil pump 2 and the pressing oil pump 4 in this state are set as the initial state, and the cutting angle between the cutting edge of the shear knife and the horizontal direction is 2°, the control system 19, through the inclination sensor 18 The inclination angle X calculates the actual cutting angle between the knife edge and the horizontal direction at this time; at this time, the X value is 0.5°, and the actual cutting angle is 2.5°

Abstract

The invention discloses a double-pump plate shearing machine and a control method thereof, and belongs to the field of a plate shearing machine. The double-pump plate shearing machine comprises a tool rest, an oil pump motor, a main oil pump, an oil tank, a main oil cylinder, an auxiliary oil cylinder, a pressing oil cylinder, a pressure switch, a pressing oil pump, a main overflow valve, a pressing overflow valve, a combined three-position four-way reversing valve, a two-position four-way reversing valve I, a two-position four-way reversing valve II, a three-position four-way reversing valve, a one-way sequence valve and an electromagnetic ball valve, wherein a tilt angle sensor is arranged on the tool rest; the tilt angle sensor is connected with an external control system; the oil tank is connected with the main oil pump and the pressing oil pump; the oil pump motor is connected with the main oil pump and the pressing oil pump. The double-pump plate shearing machine has the advantages of large pressing force of the plate shearing machine, high shearing angle regulation accuracy and high automation degree.

Description

technical field [0001] The invention relates to the field of shearing machines, and more specifically, to a double-pump shearing machine and a control method thereof. Background technique [0002] The hydraulic shearing machine is a hydraulically driven shearing device, which is often used to shear plates such as steel plates. Its basic structure is that the lower blade is fixedly installed on the frame, the upper blade is installed on the upper knife seat that moves up and down, and the upper knife seat is driven by the oil cylinder to provide shearing force to process the plate to be cut. There are two types of shears in the prior art, single-cylinder and double-cylinder. As the upper blade of the shearing machine is usually set at a certain angle relative to the lower blade, the upper blade seat has the thrust of the oil cylinder and the shear point of the shearing point when cutting. The reaction force is not in a straight line, that is, when the upper knife seat receiv...
