Embodiment 1

[0025] Refer to attached figure 1 , Figure 2 and image 3 .

[0026] The CNC forging hydraulic press that can realize reactive power compensation includes a hydraulic frame, a movable beam, a workbench, a display, an electrical controller and a power mechanism. The electrical controller controls the power mechanism to drive the hydraulic frame and the movable beam, and the electrical controller is connected to the display. The hydraulic press is equipped with a reactive power compensator and a reactive power compensation controller. The structure of the reactive power compensator consists of a knife switch 1 and an AC contactor 6. The compensation capacitor 8 is connected to the main circuit of the three-phase power supply of the oil pump motor. The reactive power There are 10 groups of compensators, and the reactive power compensation controller is connected to control the AC contactor of the reactive power compensator to realize the connection of one group, multiple groups ...

Abstract

The present invention relates to a numerically-controlled forging hydraulic press capable of implementing reactive power compensation, belonging to the field of hydraulic press technology. It includes the following several portions: hydraulic press machine frame, movable transverse beam, working table, display, electric controller and power mechanism. The electric controller can be used for controlling power mechanism to drive hydraulic press machine frame and movable transverse beam, the electric controller is connected with display. It is characterized by that the hydraulic press possesses a reactive power compensator and a reactive power compensation controller. The structure of said reactive power compensator is a three-phase power supply main circuit capable of making the compensation capacitance be connected into the oil pump motor by means of contactor, the reactive power compensation controller is connected with the control contactor.

Description

technical field [0001] The invention belongs to the technical field of hydraulic presses, in particular to a numerical control forging hydraulic press capable of realizing reactive power compensation. Background technique [0002] At present, hydraulic press equipment, as a basic processing equipment, is widely used in various fields of manufacturing industry: automobile, aerospace, powder and other industrial fields. Among the many hydraulic press series, forging hydraulic press is a new hydraulic press series that has been gradually developed in recent years. [0003] Because the workpieces processed by forging hydraulic machines are usually steel ingots, titanium alloys and other materials, the blanks need to be heated first during processing, and the temperature is usually 900--1200°C to reduce the deformation resistance of the materials. Therefore, the downward speed of the slider is required to be as fast as possible. The speed is fast, avoiding the temperature drop o...
