Abstract
The utility model discloses a press feedback device of a digital servo press machine. The press feedback device comprises a programmable controller and a servo driver and is characterized in that a digital to analog converting module is installed between the programmable controller and the servo driver. The load current of a servo motor is converted into a press feedback single by adopting the digital to analog converting module, so that the goal of accurately controlling press is achieved, and the accuracy of press control can reach 0.1 kg in theory and can be controlled at 10 kg according to actual requirement. The control mode thoroughly solves the problems that the traditional control mode is inconvenient for accurate press control and personal errors are brought by users.
Description
Technical field
The utility model relates to the digital servo forcing press, especially the pressure feedback device of digital servo forcing press.
Background technology
At present, the control of the pressure of forcing press all is to adopt the design pressure equivalence of the lathe actual pressure when using, lathe is felt the size of pressure by operator's experience when operation, the pressure degree of accuracy that this pressure controling mode makes slide block act on the mould is not high, because failure and other reasons may cause superpressure or under-voltage error at several tons even tens tons, be difficult to reach the requirement of making high-precision mold and stamping parts.
Summary of the invention
The purpose of this utility model is to act on pressure on the mould in order accurately to measure slide block, and the spy provides a kind of pressure feedback device of digital servo forcing press.
The utility model is achieved through the following technical solutions for this reason: the pressure feedback device of digital servo forcing press, comprise programmable controller, servo-driver, it is characterized in that: between described programmable controller, servo-driver, be provided with D/A converter module.
Beneficial effect:
Thereby the utility model adopts D/A converter module to convert the load current of servomotor to purpose that pressure feedback signal reaches accurate controlled pressure, and pressure controling precision can reach 0.1kg in theory, and we are controlled at 10kg according to actual needs.This control mode has thoroughly solved the problem that is not easy to the human error that accurate pressure control and user bring in the traditional control method.
Description of drawings
Fig. 1 is that link of the present utility model shows and boils figure.
The specific embodiment
As shown in Figure 1, the pressure feedback device of digital servo forcing press is to be connected with D/A converter module between programmable controller in the forcing press control system and the servo-driver.D/A converter module (A/D module) converts the load current of servomotor to data signal by the pressure feedback signal that servo-driver transmits, again data signal is passed to programmable controller, thereby reach the purpose of accurate controlled pressure, pressure controling precision can reach 0.1kg in theory, and we are controlled at 10kg according to actual needs.
