Abstract
The utility model discloses a punch feeding protection circuit which comprises a feeding line, a detection circuit, an alarm circuit and an executive circuit. The punch feeding protection circuit is simple in circuit theory and easy in implementation, and effectively protects the safety of a punch and a mould.
Description
Technical field
The utility model relates to the securing member manufacture field, and especially the punch press circuit is used in securing member processing, is specially punch press feed holding circuit.
Background technology
Larynx is the securing member of soft or hard pipe junction, solve when minor diameter soft or hard pipe connects and the dead angle to occur, produce the leakage problem of liquids and gases, be widely used in the auxiliary equipment of machines such as motor vehicle, petrochemical industry, pharmacy, food wine brewing sewage disposal purifying and dedusting auto parts machinery.The larynx assembling need be used punch press, and punch press is exactly a punching type forcing press, because in process of production, the phenomenon that the supply line of punch press can occur arching upward easily causes the damage of punch press and mould.
The utility model content
The purpose of this utility model provides a kind of punch press feed holding circuit, and easily arching upward with the punch press supply line that solves prior art causes the problem of punch press and mould damage.
In order to achieve the above object, the technical scheme that the utility model adopted is:
Punch press feed holding circuit, include supply line, detection circuit, warning circuit, executive circuit, it is characterized in that: described detection circuit includes power supply, described power supply one end has access to probe, the power supply other end is serially connected with power supply relay, protection input/contact button successively, described probe is near described supply line, and described supply line is electrically connected with described protection input/contact button; The parallel circuit of described warning circuit for constituting by three branch roads, described parallel circuit two ends are electrically connected with external electrical network, have access to the control power supply indicator in first branch road of parallel circuit, have access to the relay of series connection each other in second branch road of parallel circuit, the normally opened contact of described power supply relay, have access to the normally opened contact of described relay in the 3rd branch road of parallel circuit, Bing Lian alarm bell and malfunction indicator lamp each other, the normally opened contact of described relay and the alarm bell that is connected in parallel to each other, malfunction indicator lamp is connected mutually and is constituted the 3rd branch road of parallel circuit; Described executive circuit comprises PLC, and the output of described PLC is electrically connected with the control circuit of punch press, has access to another normally opened contact of described relay between two input terminals of described PLC.
Described punch press feed holding circuit is characterized in that: described supply line is by lead ground connection.
The utility model circuit theory is simple; easy to implement; when the supply line arch camber; then supply line can contact with probe; trigger the detection circuit conducting, and then make warning circuit, executive circuit conducting, pass through the PLC of executive circuit at last the punch press snub; warning circuit sends sound and light alarm simultaneously, thereby has protected the safety of punch press and mould.
Description of drawings
Fig. 1 is the utility model detection circuit figure.
Fig. 2 is the utility model warning circuit figure.
Fig. 3 is the utility model executive circuit figure.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3.Punch press feed holding circuit includes supply line L, detection circuit, warning circuit, executive circuit, and supply line L is by lead ground connection.Detection circuit includes power supply U, and power supply U one end has access to probe T, and the power supply U other end is serially connected with power supply relay J1, protection input/contact button TW successively, and probe T is near supply line L, and supply line L is electrically connected with protection input/contact button TW; The parallel circuit of warning circuit for constituting by three branch roads, the parallel circuit two ends are electrically connected with outside 220V electrical network, have access to control power supply indicator LD in first branch road of parallel circuit, have access to the relay J 2 of series connection each other in second branch road of parallel circuit, the normally opened contact J1-1 of power supply relay J1, have access to the normally opened contact J2-1 of relay J 2 in the 3rd branch road of parallel circuit, Bing Lian alarm bell DM and malfunction indicator lamp HD each other, the normally opened contact J2-1 of relay J 2 and the alarm bell DM that is connected in parallel to each other, malfunction indicator lamp HD connects mutually and constitutes the 3rd branch road of parallel circuit; Executive circuit comprises PLC, and the output of PLC is electrically connected with the control circuit of punch press, has access to another normally opened contact J2-2 of relay J 2 between two input terminals of PLC.
