Description
Technical field
The utility model relates to a kind of forcing press, relates in particular to a kind of press tonnage display unit, belongs to pressing equipment technical field.
Background technology
Forcing press is a kind of conventional punching production equipment, forcing press works under certain pressure and could normally work, complete the punching press to workpiece, but too high or too low pressure all can bring problem, too low pressure makes normally stamped workpieces of forcing press, and the overload of too high pressure meeting build-up of pressure machine is damaged.Existing forcing press adopts traditional pressure formula safety block that collapses; press crankshaft rotation; drivening rod device, ball screw transferring power, slide block moves up and down in orbit; when slide block overloads; crush safety block, to protect lathe, but press the formula safety block that collapses to exist and can not reuse; belong to consumable accessory, cause use cost high.Therefore, in the control circuit of existing forcing press, increase a kind of press pressure display control unit, to prevent that forcing press from occurring that pressure anomaly build-up of pressure machine can not normally be produced or the damage of forcing press has practical significance.
Utility model content
The purpose of this utility model is to provide a kind of press tonnage display unit, solves the technical problem that the abnormal build-up of pressure machine of existing press pressure can not normally be produced or forcing press damages.
the purpose of this utility model is achieved by the following technical programs:
A kind of press tonnage display unit, comprise pressure sensor 1, pressure display unit 2, resistance R, the model of described pressure sensor 1 is MBS300, the model of pressure display unit 2 is the AKT4 of Panasonic, 1 pin of described pressure display unit 2, 2 pin are power input, 8 pin and 10 pin are sensor voltage signal input, the PE pin ground connection of described pressure sensor 1, pressure sensor 1+connect the positive pole of direct current 24V power supply after the described resistance R of end series connection, pressure sensor 1-8 pin of termination pressure display unit 2, 1 pin of described pressure display unit 2, 2 pin connect alternating current 220V power supply, 10 pin of described pressure display unit 2 connect the negative pole of direct current 24V power supply.
The purpose of this utility model can also further realize by following technical measures:
Aforementioned a kind of press tonnage display unit, 3 pin of described pressure display unit 2,4 pin output pressure upper limit alarm signals, 6 pin, 7 pin output pressure lower limit alarm signals, 3 pin of described pressure display unit 2,4 pin, 6 pin, 7 pin connect forcing press control circuit 3.
Compared with prior art; the beneficial effects of the utility model are: press tonnage display circuit of the present utility model; there is precision high; clear display advantage, tradition is pressed the formula safety block that collapses relatively, has pressure alarm bound adjustable controlled; simple in structure; be quick on the draw, reusable, effectively protect the normal work of forcing press.
Accompanying drawing explanation
Fig. 1 is circuit diagram of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.As shown in Figure 1, the utility model press tonnage display unit, comprise pressure sensor 1, pressure display unit 2, resistance R, the model of described pressure sensor 1 is MBS300, the model of pressure display unit 2 is the AKT4 of Panasonic, 1 pin of described pressure display unit 2, 2 pin are power input, 8 pin and 10 pin are sensor voltage signal input, the PE pin ground connection of described pressure sensor 1, pressure sensor 1+connect the positive pole of direct current 24V power supply after the described resistance R of end series connection, pressure sensor 1-8 pin of termination pressure display unit 2, 1 pin of described pressure display unit 2, 2 pin connect alternating current 220V power supply, 10 pin of described pressure display unit 2 connect the negative pole of direct current 24V power supply.3 pin of described pressure display unit 2,4 pin output pressure upper limit alarm signals, 6 pin, 7 pin output pressure lower limit alarm signals, 3 pin of described pressure display unit 2,4 pin, 6 pin, 7 pin connect forcing press control circuit 3.
The pressure of pressure sensor 1 detected pressures machine of the present utility model; pressure detecting scope is 0-400bar; force value is converted to voltage signal and sends into pressure display unit 2; pressure display unit 2 shows force value; operating personnel shut down forcing press when force value exceeds normal range (NR), to prevent fault.This pressure display unit 2 can also arrange force value upper and lower limit scope; when forcing press actual pressure value goes beyond the scope, by 3 pin, 4 pin output pressure upper limit alarm signals, 6 pin, 7 pin output pressure lower limit alarm signals; alarm signal input pressure machine control circuit 3, controls lathe and shuts down.The utlity model has precision high, clear display advantage, tradition is pressed the formula safety block that collapses relatively, has pressure alarm bound adjustable controlled, simple in structure, is quick on the draw, reusable, effectively protects the normal work of forcing press.
In addition to the implementation, 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.
