Abstract
The invention relates to an intelligent blanking die with a pressure detecting function and belongs to the technical of metal stamping. The intelligent blanking die comprises an upper die base and a lower die base which are oppositely arranged, a male die is arranged on the upper die base, a female die is arranged on the lower die base, a female die hole matched with the male die is formed in the female die, an opening below the female die hole is formed in the lower die base, guide columns are fixed on the lower die base, guide sleeves slidingly matched with the guide columns are arranged on the upper die base, pressure sensors are laid in the male die at equal intervals, output ends of the pressure sensors are sequentially and serially connected with an analog/digital conversion module and a central processor, and an output end of the central processor is connected with a 485 communication module.
Description
Technical field
The present invention relates to a kind of intelligent pressure detection blanking die, belong to the metal stamping technical field.
Background technology
Stamping-out processing 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 blanking die.Adopt punching process, 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 because the variations in temperature that mould in use produces, cause heat expansion effect etc., so that the accuracy of manufacture descends, and then cause the reduction of production efficiency.
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 blanking die 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 blanking die, 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, be shaped with the die hole that cooperates with punch on the described die, be shaped with the perforate that is positioned at die hole below on the described die shoe, be fixed with guide pillar on the described die shoe, described upper bolster be provided with guide pillar on the guide pin bushing that is slidingly matched; Even interval is equipped with pressure sensor in the described punch, and 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-die hole, 6-perforate, 7-guide pillar, 8-guide pin bushing, 9-pressure sensor.
The specific embodiment
Embodiment
The intelligent pressure detection blanking die 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, is shaped with the die hole 5 that cooperates with punch 3 on the die 4, is shaped with the perforate 6 that is positioned at die hole 5 belows on the die shoe 2, be fixed with guide pillar 7 on the die shoe 2, upper bolster 1 is provided with the guide pin bushing 8 that is slidingly matched with guide pillar 7; Punch 3 interior even intervals are equipped with pressure sensor 9, and the output of pressure sensor 9 is in series with mould/number conversion module and central processing unit successively, and 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.
