Abstract
The utility model discloses a rolling mill with a frequency conversion function and belongs to the field of metal wire processing. The rolling mill provided by the utility model comprises a rolling mill body and a rolling mill main-motor, and is characterized in that a frequency converter is connected on the rolling mill motor; a frequency converter control circuit and a contact switch circuit are also arranged on the frequency converter; and the frequency converter control circuit controls the frequency converter by controlling the contact switch circuit. With the installation of the frequency converter, the speed of the rolling mill motor is changed; uniform-speed inching, start, stop, forward and reversing of the rolling mill can be realized; and details caused by fast speed and large inertia are minimized. In addition, the rolling mill provided by the utility model is simple to install, can be used only by pressing a required button, is very convenient to operate, and is suitable for popularization and application.
Description
Technical field
The present invention relates to a kind of milling train with frequency conversion function, belong to metal wire rod manufacture field.
Background technology
Milling train is the important machinery of metal wire rod manufacture field; current milling train does not have frequency conversion function; when producing sheet metal; when sheet material is stuck, milling train cannot reverse; when milling train reduced-voltage starting, startup generally wants 3 hours ability to start for the second time after once shutting down, cannot start continuously; affect benefit, cause loss economically.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of milling train with frequency conversion function, can all start at any time, can also main story and reversing, conveniently use.
To achieve these goals, the technical solution used in the present invention is: a kind of milling train with frequency conversion function, comprise rolling mill body, rolling mill main motor, on described stand motor, be connected with frequency converter, on described frequency converter, be also provided with transducer control circuit and contact switch circuit, described transducer control circuit is controlled frequency converter and is started, stops or main story is reversed by controlling contact switch circuit.
The invention has the beneficial effects as follows: the present invention will install frequency converter, changed the speed of stand motor, make milling train at the uniform velocity crawl, start, stop, main story and reversing, reduce because speed is fast, the details of the large generation of inertia.When the present invention installs simply, uses in addition, press the button needing, operation is very easy, suitable applying.
Accompanying drawing explanation
Fig. 1 is control flow schematic diagram of the present invention.
Embodiment
The present invention is further detailed explanation with preferred embodiment by reference to the accompanying drawings now.
Referring to Fig. 1, the present invention includes rolling mill body, rolling mill main motor, on described stand motor, be connected with frequency converter, frequency converter is voltage frequency converter or pwm cycloconverter.On described frequency converter, be also provided with transducer control circuit and contact switch circuit, described transducer control circuit is controlled frequency converter and is started, stops or main story is reversed by controlling contact switch circuit, the present invention will install frequency converter, changed the speed of stand motor, make milling train at the uniform velocity crawl, start, stop, main story and reversing, reduce because speed is fast, the details of the large generation of inertia.When the present invention installs simply, uses in addition, press the button needing, operation is very easy, suitable applying.
