The invention discloses an integrated mixed driving type double-cylinder serial pressurizing oil press and belongs to the field of forging and pressing equipment. A driving mode of a three-phase asynchronous motor is replaced by a servo motor driving mode and a transmission mode of a nut pair of a ballscrew of an electric spiral press is applied to a conventional oil pressure. First, higher stroke and return speed demand is achieved by the conventional oil pressure, so that the fast forging frequency of the conventional oil pressure is improved; second, the response speed, precision and flexibility of the press process of a control system are improved by means of the servo driving technology, the process range of the control system is expanded, the energy is saved and the emission is reduced, and the structure of the conventional hydraulic system is simplified; then, a one-way plunger type cylinder structure of the conventional oil press is replaced by the double-cylinder serial pressurizing one-way plunger type cylinder, so that the pressurizing function can be achieved and the forging efficiency is increased; and finally, an alternating servo motor drives the nut pair of the lead screw to move, so that the return cylinder and return structure of the conventional press are cancelled, and therefore, the press is simple in structure and small in load of a movable cross beam.
Description
technical field [0001] The invention belongs to the field of forging equipment, in particular to an integrated hybrid drive type double-cylinder series booster oil press. Background technique [0002] The free forging hydraulic press is a technical equipment that realizes press processing by matching the corresponding hydraulic system with the press body. In recent years, major developed industrial countries in the world have devoted themselves to the research of press fast forging to improve productivity. At present, the working form of the traditional free forging press in China is mainly a three-phase asynchronous motor to drive the oil pump, and the supporting hydraulic system provides the working pressure for the press, and the main cylinder and the return cylinder drive the movable beam to make the stroke and return movement. However, this work form has the following problems: First, the control circuit of the hydraulic system is not only complex in structure, slow in ...
