Abstract

The invention relates to an intelligent pressure detection stamping die and belongs to the technical field of metal stamping. The intelligent pressure detection stamping die comprises an upper die holder and a lower die holder which are arranged opposite to each other, wherein a male die is arranged on the upper die holder; a female die is arranged on the lower die holder; a pressing plate for blank pressing of a stamping forming piece is arranged on the female die; the female die comprises a female die plate and a coaming plate connected with the lower die holder and the female die plate; the lower die holder, the female die plate and the coaming plate form a forming cavity; a forming hole through which the male die can go in and come out of the forming cavity is formed in the female die plate; pressure sensors are paved in the male die and the female die uniformly at intervals; the output ends of the pressure sensors are connected with an analog/digital conversion module and a central processing unit sequentially; and the output port of the central processing unit is connected with a 485 communication module.

Description

A kind of intelligent pressure detection diel
Technical field
The present invention relates to a kind of intelligent pressure detection diel, belong to the metal stamping technical field.
Background technology
Punch process in the machining occupies an important position in the processing industry of national economy.The application of sheet metal component is extremely extensive, is deep into manufacturing various aspects, and sheet material forming is mainly realized by diel.Adopt Sheet Metal Forming Technology, have that precision is high, efficient is high, quality is good, save the series of advantages such as cost, economical with materials and the energy.
At present, people are more and more higher to the requirement of the precision of machine-building, to the also just thereupon raising of required precision of mould, but mould in use can produce wearing and tearing unavoidably, and the precision of processing materials itself is not high, and these all can cause pressure uneven, and is very large on accuracy of manufacture impact.
Summary of the invention
The technical problem to be solved in the present invention is, and is not enough for prior art, but proposes a kind of diel of each point pressure of at-once monitor mould.
The present invention is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of intelligent pressure detection diel, comprise the upper bolster and the die shoe that are oppositely arranged, described upper bolster is provided with punch, described die shoe is provided with die, described die is provided with the pressing plate for the flanging of punch forming part, described die comprises concave template and the coaming plate that is connected die shoe and concave template, described die shoe, concave template and coaming plate are formed into die cavity, be shaped with the forming hole for punch turnover forming cavity on the described concave template, even interval is equipped with pressure sensor in described punch and the die, the output of described pressure sensor is in series with mould/number conversion module and central processing unit successively, and the output port of described central processing unit is connected with 485 communication modules.
The present invention further improves and is: described pressure sensor is made of the Wheatstone bridge that a piezo-resistance and three fixed value resistance form; The input access power supply of described Wheatstone bridge; The output of described Wheatstone bridge connects described mould/number conversion module.
The present invention further improves and is: be in series with successively difference amplifier and low pass filter between described Wheatstone bridge and the described mould/number conversion module.
The present invention adopts the beneficial effect of technique scheme to be: adopt pre-buried pressure sensor in mould, sensing data is sent to external man-machine interface via general 485 interfaces, just can easily observe the pressure distribution of the mould each point in the work, immediately pinpoint the problems, and can accurately confirm problem points, in time adjust via manual intervention, guarantee the accuracy of manufacture.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the circuit diagram of the embodiment of the invention.
Number in the figure is schematically as follows: 1-upper bolster, 2-die shoe, 3-punch, 4-die, 5-profiled member, 6-pressing plate, 7-concave template, 8-coaming plate, 9-pressure sensor.
The specific embodiment
Embodiment
The intelligent pressure detection diel of the present embodiment, as shown in Figure 1, comprise the upper bolster 1 and the die shoe 2 that are oppositely arranged, upper bolster 1 is provided with punch 3, die shoe 2 is provided with die 4, die 4 is provided with the pressing plate 6 for the flanging of punch forming part, die 4 comprises concave template 7 and is connected the coaming plate 8 of die shoe 2 with concave template 7, die shoe 2, concave template 7 and coaming plate 8 are formed into die cavity, be shaped with the forming hole for punch 3 turnover forming cavities on the concave template 7, punch 3 and die 4 interior even intervals are equipped with pressure sensor 9, the output of pressure sensor 9 mould/number conversion module and the central processing unit of connecting successively, the output port of central processing unit is connected with 485 communication modules.
Shown in Fig. 2 circuit, pressure sensor 9 is made of the Wheatstone bridge that a piezo-resistance and three fixed value resistance form; The input access power supply of Wheatstone bridge; The output of the Wheatstone bridge connection mode/number conversion module behind difference amplifier and the low pass filter of connecting successively.
During work, by general 485 communication modules, connect a host computer, host computer is preinstalled with image conversion software, can intuitively must observe each pressure sensor 9 state of the mould in this enforcement, in the course of the work as find any pressure anomaly, perhaps certain only/some pressure sensor 9 numerical value deviation is excessive, then send alarm signal, notify operating personnel at once.Perhaps, when finding that profiled member 5 appearance are bad, in time check data, confirm whether the pressure of bad point has unusually.
The present invention is not limited to above-described embodiment.All employings are equal to replaces the technical scheme that forms, and all drops on the protection domain of requirement of the present invention.
