Punching structure of NC turret punch machine application switch reluctance servo motor

Abstract

The invention provides an energy-saving, environmentally-friendly, efficient and maintenance-free punching structure of an NC turret punch machine application switch reluctance servo motor, comprising a switch reluctance servo motor, a crank shaft, a connecting rod and a slide block, wherein the switch reluctance servo motor is connected with the crank shaft, the crank shaft which is directly driven by the switch reluctance servo motor is connected with the connecting rod, and the connecting rod is connected with the slide block so as to form a planar linkage. The switch reluctance servo motor can be directly arranged at one end of the crank shaft in the number of one and can be respectively directly arranged at both ends of the crank in the number of two, and the crank shaft is synchronously driven by the switch reluctance servo motor.

Description

technical field [0001] The invention relates to a structure of a numerically controlled turret punch press, in particular to a stamping structure using a switched reluctance servo motor for a numerically controlled turret punch. Background technique [0002] The stamping main transmission part of the traditional CNC turret punch press has two structures: mechanical and hydraulic. [0003] The mechanical type is that the AC asynchronous motor drives the flywheel to rotate at a high speed, and the crankshaft mechanism of the mechanical main drive is driven by the combination of the clutch to complete the stamping action during stamping. When the stamping action is completed, the clutch is disengaged, but the AC asynchronous motor does not stop, and is always in a high-speed running state. Moreover, the upper dead center and the lower dead center of stamping cannot be changed, which is not conducive to the forming or embossing of plates and other processes. Due to the limitat...

Problems solved by technology

However, the shortcomings of the hydraulic system are also very obvious. First of all, it consumes a lot of power. The oil pump motor of the hydraulic station is always in a high-speed operation state. In view of the leakage characteristics of the oil pump itself, to maintain an accurate position, it must be kept running to keep the pressure constant.

In addition, the hydraulic system has high requirements on the particles of hydraulic oil, requiring regular replacement of hydraulic oil and working filter elements every year, so the user's use and maintenance costs are high

There is also the discharge of waste oil, which is also polluting the environment.
