Description
Technical field
The utility model belongs to the forging machinery and equipment technical field, particularly a kind of servo type electric screw press.
Background technology
Along with the fast development of Chinese Automobile Industry ', high ferro and engineering machinery, forging will be with 40% growth rate development in following every year, and the annual market demand of metal forming machinery will be 30% increasing degree and increase.Three kinds of capital equipments of metal forming machinery are fly press, die hammer and hotdie forging press; Difference according to type of drive; Fly press is divided into friction, hydraulic pressure, clutch and electronic four types of fly presses again; Wherein electric screw press adopts the kind of drive that motor directly drives; With hydraulic servo and the mechanical drive mode that replaces extensively adopting in the past; Electric screw press is simple in structure with it, volume is little, driving-chain is short, simple operation, security of operation, maintenance load are little, the process application wide ranges, the operation noise is little, blow efficiency is high and can accurately control blow energy, remarkable advantage such as energy-conservation, will be used widely in motorcycle, automobile, engineering machinery, high ferro, Aero-Space, hardware & tools, tableware and nonmetal shaping industries such as (like brickmaking).
Drive scheme is the core key technology of electric screw press development, and electric screw press must solve following key technology: the choosing of (1) capacity motor; (2) effective ac speed control method confirms; (3) the torque fan-out capability during the electric motor starting state and the solution of problem of temperature rise under the loading condition; (4) design of control system schema; (5) the accurate control of energy and backward position.Simultaneously, electric screw press requires the motor can the constant torque output of Rapid Realization under big inertia loading condition, during Fraquent start, avoids too high starting current simultaneously.
