The invention discloses an energy-saving screw press system with double execution units. According to the energy-saving screw press system, two groups of screw pair mechanisms, namely a first screw pair mechanism and a second screw pair mechanism, are distributed on two sides of a press; the first screw pair mechanism is composed of a first cylinder, a first lead screw, a first sliding block and afirst anti-rotation device; the second screw pair mechanism is composed of a second cylinder, a second lead screw, a second sliding block and a second anti-rotation device; the first lead screw is directly driven by a main motor through a synchronous belt; the second lead screw is driven by the main motor and an auxiliary motor through the synchronous belt after the motion synthesis by a differential gear system; the motion characteristics of the first sliding block and the second sliding block are detected and acquired through a first displacement sensor and a second displacement sensor in aone-to-one correspondence manner, and transferred to a controller; and the controller is utilized for controlling the working states of both the main motor and the auxiliary motor. By adoption of theenergy-saving screw press system disclosed by the invention, the two screw pair mechanisms can be connected by utilizing the differential gear system, the complementary action between the execution units of the press can be achieved, and the energy efficiency and the working efficiency of the press can be remarkably improved.
Description
technical field [0001] The invention relates to an energy-saving flexible double-execution unit screw press system, which is used to maintain high motor efficiency, reduce energy loss during the operation of the press, and improve the working efficiency and energy utilization rate of the press. It still has a certain degree of flexibility and can handle various complex working conditions. Background technique [0002] Forming processing is widely used for its advantages of high production efficiency, material saving and high processing quality. The mechanical screw press has stable transmission and high control precision. With the improvement of factory automation, it will have an important place in the press market in the future. [0003] Due to the forming characteristics of the press machine, the motor operates with high energy efficiency only during the short pressing process, and the energy efficiency of the motor is low in other stages, and there is a large amount of ...
