Description

Press machine with ultra-long table top and multiple connecting rods and single-power double-side driving function
Technical Field
The utility model relates to a high-speed press machine, in particular to an overlong table-board multi-connecting-rod type single-power double-side-driven press machine.
Background
With the arrival of the industry 4.0 and the continuous development of automation and informatization, the application range of the motor is wider and wider, and the requirement on the motor is higher and higher. The thickness of the motor iron core stator and the motor iron core rotor is gradually reduced from 0.5mm to 0.35mm, 0.25mm and even 0.2 mm.
The iron core stator and the iron core rotor are used as core components of the motor, and the quality of the precision of the iron core stator and the iron core rotor directly influences the quality of the motor. The thinner the core material, the smaller the gap between the female punches in the die and the corresponding higher the precision requirements for the press. Meanwhile, in order to save materials and improve efficiency, the shapes of the stator and rotor dies must be longer, and the table surface of a high-speed punch press using the dies must be longer. Conventional high speed presses have not been able to meet the production requirements of this type of product.
A common high-speed press machine only uses a high-power single-output motor to control a clutch brake unit at one end of a main shaft so as to control the action of the press machine. However, when the table top is too long, the spindle is also correspondingly long, only accurate control of one end of the spindle can be realized, and action lag may occur on the other side, so that the movement of each connecting rod on the spindle is asynchronous, and the running accuracy of the machine tool is directly influenced. The other is that two low-power single-output motors are used for respectively controlling two clutch brake units at two ends of the main shaft so as to control the action of the press machine. However, due to the manufacturing difference of the motors and the uncertainty of the respective control, the movement of the two ends of the spindle may be inconsistent, so that the movement of each connecting rod on the spindle is asynchronous and the operation precision of the machine tool is directly influenced. The two high-speed presses can not meet the high-speed precision stamping requirement of the thickness of the ultrathin materials of the stator and the rotor of the current motor iron core.
