Problems solved by technology

Aiming at the problem of reducing the power of servo press motors, there are two main types of servo presses currently developed or produced: full servo presses and hybrid drive servo presses. The energy of full servo presses is provided by servo motors, but during processing For large workpieces, the displacement of the workpiece often occurs, which affects the processing quality

Abstract

The invention relates to the technical field of machining equipment, in particular to a four-point eccentric mechanical press. The four-point eccentric mechanical press comprises a frame, a pressing device, a pressure device and a feeding device; the pressing device comprises a feeding mechanism and a pressing mechanism, the feeding mechanism is arranged at the upper end of the frame and comprises a feeding trolley, a motor driving device is arranged on the feeding trolley, and is in driving connection with the feeding trolley, the pressing mechanism comprises a pressing arm, and the pressing arm is arranged in a supporting frame, and is connected with the supporting frame through a rotating shaft; and the pressure device comprises a pressure arm, a fixing frame and a box, the box is arranged on one side of the frame, and the front end of the box is fixedly connected with a connecting frame. The pressing device and the pressure device can play a role in limiting the position of a workpiece, and the problem that the machining quality is affected due to the fact that a large workpiece is often displaced when machined is solved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a four-point eccentric mechanical press. Background technique [0002] At present, with the increasingly fierce international competition in the manufacturing industry, the demand for manufacturing high-efficiency, high-precision, and high-quality servo presses is becoming stronger and stronger. The servo press has the following characteristics: (1) Flexible and intelligent production. The servo press can adopt corresponding optimization curves according to different processes. (2) Energy saving and environmental protection. In ordinary presses, flywheel idling energy consumption accounts for 6% to 30% of total energy consumption, and clutch energy consumption accounts for 20% of total energy consumption. The servo motor cancels the flywheel and the clutch, simplifies the transmission system and saves energy consumption. (3) High precision, high produc...
