Abstract
The utility model discloses a double-cam control device for a mechanical press. The double-cam control device comprises a motor, a crankshaft, a mechanical cam device, a programmable logic controller (PLC) and an electromagnetic valve, wherein the motor is connected with the crankshaft; the crankshaft is connected with the mechanical cam device; the mechanical cam device is connected with the PLC and a switch signal is input into the input end of the PLC; the electromagnetic valve is connected with the output end of the PLC; and the double-cam control device also comprises a photoelectric encoder connected with the input end of the PLC. The device is a double-cam loop control system, an electronic cam and a mechanical cam simultaneously or separately can control a punch of the press to work or stop, and the running safety reliability of the press is improved.
Description
Technical field
The utility model relates to a kind of punching machine, relates in particular to a kind of punching machine double cam control device, belongs to the pressing equipment technical field.
Background technology
Single mechanical cam control device is adopted in the control of existing press ram; Motor drives main shaft (bent axle) operation; And drive the mechanical cam running to position near switch through the main transmission band, and sending the switching value signal after being triggered near switch and give PLC, PLC sends signal and stops magnetic valve work; Make main shaft out of service, thereby make press ram be parked in the desired position.The cam drive band fractures and camshaft fracture or skidding owing to the mechanical cam control device often takes place, and mechanical cam does not have due effect, and connecting towards fault appears in forcing press, influences the normal operation of forcing press, and might damage the person.Therefore the cam control gear to press ram improves, and is very necessary to improve the forcing press reliability of operation.
Summary of the invention
The purpose of the utility model is to provide a kind of pneumatic press double cam control device, solves single mechanical cam control device and is prone to break down, and influences the normal operation of forcing press and the technical problem that threatens personal safety.
The purpose of
the utility model is achieved through following technical scheme:
A kind of punching machine double cam control device comprises motor 1, bent axle 2, mechanical cam device 4, PLC5, magnetic valve 8, and motor 1 links to each other with bent axle 2; Bent axle 2 links to each other with mechanical cam device 4; Mechanical cam device 4 links to each other with PLC5, and switching signal is input to the input of PLC5, and magnetic valve 8 links to each other with the output of PLC5; Also comprise photoelectric encoder 3, photoelectric encoder 3 links to each other with the input of PLC5.
The purpose of the utility model can also further realize through following technical measures:
Aforesaid punching machine double cam control device also comprises touch-screen 6, feeding structure 7, and touch-screen 6 links to each other with PLC5, communicates, and feeding structure 7 links to each other with the output of PLC5.
Compared with prior art, the beneficial effect of the utility model is: this device is a kind of double cam loop control system, can realize electric cam and mechanical cam simultaneously or separately controlled pressure machine drift running, stop, having improved forcing press property safe and reliable to operation.
Description of drawings
Fig. 1 is the circuit diagram of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
As shown in Figure 1, the utility model comprises motor 1, bent axle 2, mechanical cam device 4, PLC5, magnetic valve 8, touch-screen 6, feeding structure 7, and motor 1 links to each other with bent axle 2; Bent axle 2 links to each other with mechanical cam device 4, and mechanical cam device 4 links to each other with PLC5, switching signal is input to the input of PLC5; Magnetic valve 8 links to each other with the output of PLC5; Touch-screen 6 links to each other with PLC5, communicates, and feeding structure 7 links to each other with the output of PLC5.The utility model also comprises photoelectric encoder 3, and photoelectric encoder 3 links to each other with the input of PLC5.
Motor 1 drives bent axle 2 operations; And drive 4 runnings of mechanical cam device to position near switch through the main transmission band; Send the switching value signal after being triggered near switch and give PLC5; PLC5 sends signal and stops magnetic valve 8 work, makes main shaft out of service, thereby makes press ram be parked in the desired position.Simultaneously, photoelectric encoder 3 is followed bent axle 2 operation and is sent pulse and carry out computing to PLC5, thus controlled pressure machine spindle operation and the position that stops.Duplicate protection is carried out in the operation of mechanical cam device 4 and 3 pairs of forcing presses of photoelectric encoder, and can output signal to outside feed mechanism 7 through PLC5, controls outside feed mechanism 7 and forcing press cooperating.
The utility model is installed the double loop cam controller, if the control of the cam in arbitrary loop is broken down, forcing press quits work immediately; Cam gear to fault loop after stopping overhauls, and recovers processing.Tight like production task, can be provided with through touch-screen 6, convert the single cam of implementation loop to and operate, to satisfy the needs of urgent production task.
Except that the foregoing description, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
