Abstract
The utility model discloses a die assembly height digital display device used on a press machine, which belongs to the technical field of press machines and comprises a coded disc arranged on a worm of a die assembly height adjusting mechanism of the press machine, a bracket, an approach switch, a PLC and a man-machine interface connected with the PLC; a round of circular holes are uniformly distributed close to the periphery of the coded disc by taking the centre of circle as the center; the approach switch is positioned at one side of the coded disc and arranged on the bracket corresponding to the position of the circular hole; and the approach switch is connected with the PLC to convert acquired angular displacement signals into pulse signals to be transmitted to the PLC, and the man-machine interface displays the die assembly height after the signals are processed by the PLC. The device converts the angular displacement signals of the worm in the die assembly height adjusting mechanism into the pulse signals by the coded disc and the approach switch, the pulse signals are processed by the PLC, and the digital display of the die assembly height is realized by the man-machine interface. The utility model has the advantages of simple and reliable structure, high resolution and low cost, is convenient to maintain and can realize the digital display of the die assembly height of the press machine.
Description
Technical field
The utility model relates to a kind of digital display device, specifically is the height of packing compact digital display device that uses on a kind of forcing press.
Background technology
Known pressure machine height of packing compact digital display device is to be made of rotary encoder and control system thereof at present, converts angular displacement to pulse signal by encoder, shows height of packing compact after the control system received signal.But in the use of forcing press, because that forcing press vibrations often cause encoder to connect is loosening, or encoder is badly shaken, and it is incorrect to cause height of packing compact to show.
Summary of the invention
In order to overcome because of encoder connects the incorrect problem of digital display loosening or that damage causes, the utility model provides the height of packing compact that uses on a kind of forcing press digital display device, the height of packing compact of demonstration forcing press that can be more simple and reliable.
The utility model is realized with following technical scheme: a kind of forcing press height of packing compact digital display device comprises code-disc on the worm screw that is installed in forcing press height of packing compact governor motion, support, near switch, PLC Programmable Logic Controller and the man-machine interface that is connected with the PLC Programmable Logic Controller; Is that center be evenly equipped with an all circular hole near periphery with the center of circle at code-disc; A side that is positioned at code-disc near switch is rack-mount corresponding to the position of circular hole; Be connected the angular displacement signal that to gather with the PLC Programmable Logic Controller near switch and convert pulse signal to and flow to the PLC Programmable Logic Controller, handle the back by the PLC Programmable Logic Controller and show height of packing compact by man-machine interface; The high contactor of control mould on the forcing press in addition that is connected with the PLC Programmable Logic Controller.
Owing to adopted technique scheme, code-disc is installed on the worm screw of forcing press height of packing compact governor motion, rotation along with worm screw, utilization converts the angular displacement of code-disc to pulse signal near switch, with PLC received pulse signal, calculate the back through program and show height of packing compact by man-machine interface.As increasing counting and subtracting count signal, realized the synchronous demonstration that height of packing compact increases or reduces with the contactor signal of controlling motor positive and inverse.
The utility model has the advantages that simple and reliable for structure, the resolution ratio height, easy care, cost is low.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is described in further detail.
Fig. 1 is the utility model code-disc and near the switch installing structure schematic diagram;
Fig. 2 is the utility model electrical schematic diagram;
Fig. 3 is code-disc structure three-dimensional figure.
Among the figure: 1, code-disc, 11, circular hole, 2, support, 3, near switch, 4, the PLC Programmable Logic Controller, 5, man-machine interface, 6, contactor, 61, the contactor normally opened contact that descends of control height of packing compact, 62, the contactor normally opened contact that rises of control height of packing compact.
The specific embodiment
As shown in Figure 3, code-disc 1 is a circular cold drawing, and an equally spaced circle circular hole 11 is arranged on its surface, and what of circular hole require design according to accuracy of detection, and the accuracy of detection height of requirement, circular hole are many more, and promptly the spacing of 11 of circular holes is more little.Uniform 20 circular holes 11 of present embodiment code-disc 1 periphery.
As shown in Figure 1, code-disc 1 is installed on the worm screw of forcing press height of packing compact governor motion.To be installed on the support 2 near switch 3.Cooperate with employed operating distance with the spacing of code-disc 1 near switch 3 near switch; Present embodiment near the spacing of switch 3 and code-disc 1 in 2mm.
As shown in Figure 2, be connected the angular displacement signal that to gather with PLC Programmable Logic Controller 4 near switch 3 and convert pulse signal to and flow to PLC Programmable Logic Controller 4, handle the back by PLC Programmable Logic Controller 4 and show height of packing compact by man-machine interface 5.What be connected with the PLC Programmable Logic Controller controls the high contactor of mould 6 in addition.The contactor normally opened contact 61 that the control height of packing compact of contactor 6 descends is connected with the X1 terminal of PLC Programmable Logic Controller, the contactor normally opened contact of controlling the height of packing compact rising be connected with the X2 terminal of PLC Programmable Logic Controller.
Its course of work and principle are: do not have inverse signal during near the circular hole position of switch 3 corresponding code-discs 1, inverse signal is arranged during near the non-circular hole position of switch 3 corresponding code-discs 1; When forcing press adjusting mould is high, the worm screw rotation of height of packing compact governor motion, code-disc 1 rotates with worm screw, detects switching value signal alternately and sends PLC near switch 3.When height of packing compact raises, the high contactor connection signal that rises of control mould is returned to PLC, PLC carries out and increases counting, when height of packing compact descends, the high contactor connection signal that descends of control mould is returned to PLC, PLC execution subtracting counting, PLC calculates the back by the form demonstration height of packing compact of man-machine interface 5 with numeral through program.
