Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0015] see figure 1 , a servo direct drive power head for a press, comprising a frame 1, two side walls of the frame 1 are provided with through holes, and a pair of switching flux permanent magnet motors 2 cooperate with the through holes of the frame 1 The bolts are symmetrically installed on both sides of the frame 1, so that the whole system is symmetrical. The hollow eccentric shaft mechanism 3 is installed in the frame 1, and the shaft ends on both sides are inserted into the switch flux permanent magnet motor 2 and connected by pressing force, so that the torque generated by the motor is transmitted to the link mechanism 4 and the slider mechanism 5 on. The link mechanism 4 is installed on the eccentric shaft section in the middle of the hollow eccentric shaft mechanism 3, the slider mechanism 5 is located below the link mechanism 4, the two are conn...

Abstract

The invention provides a servo direct-driven power head for a press machine. A pair of switch magnetic flow permanent magnet motors is mounted on the two sides of a frame symmetrically; a hollow eccentric shaft mechanism is mounted inside the frame; the shaft ends on the two sides of the hollow eccentric shaft mechanism are inserted into the switch magnetic flow permanent magnet motors, and are connected through the pressing force; a link mechanism is mounted on an eccentric shaft section of the middle part of the hollow eccentric shaft mechanism; a sliding block mechanism is positioned below the link mechanism; a guiding mechanism is mounted on the frame below the link mechanism; the sliding block mechanism slides up and down inside the guiding mechanism; the link mechanism and the guiding mechanism convert the rotation of the hollow eccentric shaft mechanism into the rectilinear motion of the sliding block mechanism; an auxiliary pipeline mechanism is arranged outside the switch magnetic flow permanent magnet motors; and hollow shafts of the switch magnetic flow permanent magnet motors are connected with the hollow eccentric shaft mechanism to form a fluid flow passage. According to the invention, the motors have simple structure, high reliability, and excellent speed governing and heat dissipation performance; the power head adopts the servo direct-driven technology, has a concise structure, high transmission efficiency, and quick action, and the cost is comparatively low.

Description

technical field [0001] The invention belongs to the technical field of presses in mechanical forming equipment, and in particular relates to a servo direct-drive power head for presses. Background technique [0002] Commonly used servo motors for presses have experienced the development of DC servo motors, AC servo motors, switched reluctance motors and transverse magnetic field motors. In the 1970s, DC servo motors were widely used in mechanical equipment. However, due to the complex mechanical structure and heavy maintenance workload of the motor itself, the rotor is prone to heat during operation, and it is easy to affect the accuracy of the mechanical equipment connected to it. In the case of high speed and large capacity, the mechanical commutator has become the bottleneck of the development of DC servo drive technology, so it has not formed an effective combination with the press. The AC servo motor overcomes various shortcomings caused by mechanical components such a...
