Abstract

The invention discloses a punch with a monitoring system. The punch with the monitoring system comprises a punch body, a controller, a power supply, a self-hold circuit, a monitoring circuit and a monitoring unit, wherein the controller outputs a control signal for controlling the actuation of the punch body, the power supply supplies a electric power needed by the actuation of the controller, the self-hold circuit is electrically connected between the power supply and the controller, the monitoring circuit is electrically connected between the controller and the punch body and is used for transmitting the control signal output by the controller to the punch body, the monitoring unit is electrically connected with the controller, the self-hold circuit and the monitoring circuit so as to monitor whether the actuation of the controller is abnormal or not, and when the actuation of the controller is abnormal, the monitoring unit turns off the monitoring circuit. According to the punch with the monitoring system, whether the actuation of the controller is abnormal or not is monitored by the external monitoring unit; when the actuation of the punch is abnormal, the monitoring unit can immediately prevent the controller from transmitting the control signal to the punch body, so that the actuation safety of the punch is ensured.

Description

The punch press of tool monitoring system

Technical field

The present invention relates to a kind of punch press, be specifically related to a kind of punch press of tool monitoring system.

Background technology

Press, punch press is that metal material is pressed, and makes its plastic deformation, and obtains desired shape and precision, uses the part processing that is used for accomplishing industry such as auto industry, mechanical industry and light industry.

Consult Fig. 1, show the control mode calcspar of general punch press, its controller 11 is to provide start required electric power through a power supply 12; And this controller 11 has many signal contacts that are connected with punch press body 13, and these punch press body 13 meetings are because the control signal that this controller 11 is provided change to start or stop, and those state of a controls can show through a screen 14; Yet; Because this punch press body 13 is to utilize the characteristic of high speed stamping to accomplish machining object processing, so the vibration frequency of this punch press body 13 is extremely many and high, and these vibrations can cause this controller 11 to work as machine; And then cause these punch press body 13 starts unusual, influence safety.In addition, cause this controller 11 when the reason of machine also maybe be because the too high institute of operating temperature own cause, the controller (PC-based) that particularly uses the software resource of PC to control is worked as machine because of vibrations or too high the causing of temperature more easily.

Summary of the invention

Technical problem to be solved by this invention provides a kind of punch press of tool monitoring system, and whether it can monitor the controller start of this punch press through an outside monitoring system unusual, to guarantee the security of this punch press start.

For solving the problems of the technologies described above, the technical solution of the punch press of tool monitoring system of the present invention is:

Comprise: a punch press body; One controller, output one is in order to control the control signal of this punch press body start; One power supply provides one to supply the required electric power of this controller start; One self-hold circuit electrically connects between this power supply and this controller; One supervisory circuit electrically connects between this controller and this punch press body, in order to pass on the control signal of this controller output to this punch press body; Whether one monitoring unit electrically connects this controller, this self-hold circuit and this supervisory circuit, unusual to monitor this controller start, and unusual when this controller start, this monitoring unit then cuts off this supervisory circuit.

Further, said controller electrically connects a screen.

Further, said controller is industrial computer (Pc based).

The technique effect that the present invention can reach is:

The present invention be primarily aimed at commonly use punch press controller easily because of vibrations or too high the causing of temperature work as machine; Influence the invention that the security of punch press start is carried out; Whether unusual the present invention mainly monitoring unit through the outside carry out start monitoring to the controller of this punch press; When this controller start was unusual, this monitoring unit can make this controller stop output control signal to this punch press body, to guarantee the security of this punch press start immediately.

The specific embodiment

As shown in Figure 2, the punch press of a kind of tool monitoring system that the embodiment of the invention provided, it mainly is made up of a punch press body 20, a controller 30, a power supply 40, a self-hold circuit 50, a supervisory circuit 60 and 70 of monitoring units, wherein:

Punch press body 20 is that metal material is pressed, and makes its plastic deformation, with obtain the part processing of the shape of being wanted and precision.

Controller 30; Output one is in order to control the control signal 31 of these punch press body 20 starts; To control this punch press body 20 start and stop, the controller of this controller 30 for controlling, i.e. industrial computer (PC-based) in the present embodiment through the software resource; And this controller 30 electrically connects a screen 80, shows the immediate status of control through this screen 80.

Power supply 40 provides one to supply the required electric power of these controller 30 starts.

Self-hold circuit 50 electrically connects between this power supply 40 and this controller 30, the electric power that makes this power supply 40 through these self-hold circuit 50 conductings after self-sustaining characteristic offer this controller 30.

Supervisory circuit 60 electrically connects between this controller 30 and this punch press body 20, in order to pass on the control signal 31 of this controller 30 outputs to this punch press body 20.

Monitoring unit 70; Electrically connect this controller 30, this self-hold circuit 50 and this supervisory circuit 60; Whether unusual to monitor these controller 30 starts; Unusual when these controller 30 starts, 70 of this monitoring units cut off this supervisory circuit 60, continue to provide this control signal 31 to this punch press body 20 to stop this controller 30.What must explain is that the required electric power of these monitoring unit 60 starts is to be provided by 40 of this power supplys by self-sustaining characteristic after these self-hold circuit 50 conductings equally.

The above is the structure and the configuration explanation thereof of each main member of the embodiment of the invention.In view of the above, the present invention can have following advantage at least:

One of which, because whether unusual the present invention's 60 pairs of these controllers 30 of this monitoring unit through the outside carry out start monitoring; When these controller 30 starts were unusual, this monitoring unit 60 can cut off this supervisory circuit 50 immediately, made this controller 30 stop this control signal of output and gave this punch press body; To guarantee the security of these punch press body 20 starts; Therefore, when this controller 30 because of vibrations or temperature is too high when causing when machine, the present invention can promote the security of these punch press body 20 starts.

Two,, make this controller 30 have the shutdown delay function, avoid causing the fault of this controller 30 because of controller 30 undesired shutdown through this self-hold circuit 50 owing to be electrically connected with a self-hold circuit 50 between this controller 30 and this power supply 40.

In sum; The foregoing description and diagram are merely the present invention's preferred embodiment; When can not with the scope of qualification the present invention enforcement, the equalization of promptly doing according to claim of the present invention generally changes and modifies, and all should belong in the scope that patent of the present invention contains.
