Abstract
The utility model discloses a device for measuring speed of a flywheel of a pressing machine in the field of pressing machines. The device for measuring the speed of the flywheel of the pressing machine comprises a flywheel, wherein one half of the circumferential surface of the flywheel is coated with a dope with a color A, and the other half of the circumferential surface of the flywheel is coated with a dope with a color B; a color detector is arranged on the side surface of the flywheel; the color detector is installed on a support; and the color detector is connected with a PLC (programmable logic controller) control unit of the pressing machine. The time interval in which the flywheel rotates for a circle to trigger a signal sending contact is detected by the color detector to obtain the time for the flywheel to rotate for a circle, so that the rotation speed of the flywheel is obtained; and the device for measuring the speed of the flywheel of the pressing machine is simple in structure and low in cost and is applicable to measuring the speed of the flywheel of the pressing machine.
Description
Technical field
The utility model relates to a kind of forcing press, particularly a kind of pressure flywheel speed measuring device.
Background technology
Existing forcing press flywheel in course of normal operation is rotated in the forward, but the releasing of partial fault needs the flywheel reverse rotation, because the big inertia of flywheel mass of punching machine is also big, nature needing tens minutes to stop even the longer time.If flywheel promptly carries out reverse operating under not static situation, will directly cause burning main motor, punching machine needs the flywheel speed measuring device usually for this reason.And existing flywheel speed measuring device be generally finished product the zero-speed switch or by the induction special metal inductance approach switch constitute.
Its weak point is: the zero-speed switch costs an arm and a leg; Cost is higher; And constitute by the inductance approach switch of induction special metal, this mode need be installed specific induction metal on flywheel, because flywheel is to rotate at a high speed; And dynamic balancing there is certain requirement, has so strengthened the design difficulty of flywheel and the difficulty of processing.
The utility model content
The purpose of the utility model provides a kind of pressure flywheel speed measuring device, and this installation cost is lower, and working stability is simple in structure, processes easy.
The purpose of the utility model is achieved in that the pressure flywheel speed measuring device; Comprise flywheel; Be brushed with A look coating on the hemicycle side face of said flywheel, be brushed with B look coating on second half periphery, the side of flywheel is provided with color detector; Said color detector is rack-mount, and color detector links to each other with forcing press PLC control module.
During the utility model work; When the color on the flywheel that the color detector that is installed on the color detector mounting bracket is faced was color A, color detector was the closure signal feedback contact, when the color on the flywheel that color detector is faced is color B; Color detector is the cut-off signal feedback contact; The programmable logic controller (PLC) PLC of forcing press through the blanking time of signal calculated, judges the rotating speed of current flywheel through detecting the signal feedback contact on the color detector.The power supply of color detector is controlled through programmable logic controller (PLC) PLC, when need not detect the current rotating speed of flywheel, is promptly cut off the electricity supply by PLC, when needs detect the current rotating speed of flywheel, promptly by the PLC turn-on power.The utility model can be used for during pressure flywheel tests the speed.The utility model can be used for during pressure flywheel tests the speed.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 be among Fig. 1 A to B to view.
Fig. 3 is the control principle block diagram of the utility model.
Wherein, 1 flywheel, 1aA look coating, 1bB look coating, 2 color detector, 3 supports, 4 forcing press PLC control modules.
The specific embodiment
Pressure flywheel speed measuring device shown in Fig. 1 or 2; Comprise flywheel 1; Be brushed with A look coating 1A on the hemicycle side face of said flywheel 1, be brushed with B look coating 1B on second half periphery, the side of flywheel 1 is provided with color detector 2; Said color detector 2 is installed on the support 3, and color detector 2 links to each other with forcing press PLC control module 4.
Like Fig. 1,2, shown in 3; During the utility model work; When the color on the flywheel 1 that the color detector 2 that is installed on color detector 2 mounting brackets 3 is faced was color A, color detector 2 was the closure signal feedback contact, when the color on the flywheel 1 that color detector 2 is faced is color B; Color detector 2 is the cut-off signal feedback contact; Forcing press PLC control module 4 through the blanking time of signal calculated, is judged the rotating speed of current flywheel 1 through detecting the signal feedback contact on the color detector 2.The power supply of color detector 2 is controlled through PLC control module 4, when need not detect flywheel 1 current rotating speed, is promptly cut off the electricity supply by PLC control module 4, when needs detect flywheel 1 current rotating speed, promptly by PLC control module 4 turn-on powers.
The utility model is not limited to the foregoing description, and as half of flywheel tinted, second half is not tinted; Also can detect data through color detector; Should fall into the protection domain of the utility model equally, on the basis of the disclosed technical scheme of the utility model, those skilled in the art is according to disclosed technology contents; Do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in the protection domain of the utility model.
