Double-motor mechanical coordination in-phase slider driven eight-bar servo pressure device

Abstract

The invention relates to a key synchronizer driving eight-rod servo press coordinated with dual electric machinery. Two servomotors arranged symmetrically left and right are connected with a driving slide block by a key synchronizer driving mechanism coordinated with a set of dual electric machinery, and the driving sliding block is connected with a pressing slide block by two sets of eight-connecting bar pressing mechanism arranged symmetrically left and right. The key synchronizer driving mechanism coordinated with the dual electric machinery comprises a screw rod, a small connecting bar, ahorizontal connecting bar and a sliding stand; each set of eight-connecting bar pressing mechanism comprises a short connecting bar, an upper elbow connecting bar, a lower elbow connecting bar and a punch connecting bar. The two servomotors can drive synchronously according to the set law of motion; the key synchronizer driving mechanism coordinated with the dual electric machinery can drive the driving slide block to move, and the driving slide block can push the pressing slide block to move by the two sets of eight-connecting bar pressing mechanism, therefore, the synthesis of the movement and the power of the two servomotors can be realized, and the large-tonnage ram pressure and movement are obtained, thus realizing the large-tonnage servo pressing with lower cost.

Description

technical field

[0001] The invention relates to an eight-rod servo press driven by double-motor mechanical coordination synchronous sliders, which is suitable for plastic processing of parts and belongs to the field of servo-driven mechanical presses in mechanical engineering. Background technique

[0002] As the main tool for parts processing, mechanical presses are widely used. According to the different motors, traditional mechanical presses are divided into two types: constant speed motor and servo motor drive. A typical mechanical press is powered by a fixed-speed motor, which has poor adaptability to different stamping operations. The mechanical press driven by the servo motor has strong adaptability, and can meet the production requirements of small batches, multiple varieties, and high precision, and is more and more widely used. At present, domestic high-capacity, high-torque, low-speed servo motors are expensive, and problems such as the strength and durability o...
