Abstract
The utility model relates to an intelligent pressure detection stamping die. The die belongs to the field of metal blanking technology. The die comprises an upper die seat and a lower die seat that are oppositely disposed with each other. The upper die seat is provided with a male die, and the lower die seat is provided with a female die. The female die is provided with a stamping plate used for blank pressing of a stamping forming part. A pressurizing chamber used for connecting an external hydraulic oil input is disposed inside the male die. The female die comprises a female die plate and a coaming plate for connecting the lower die seat and the female die plate. The lower die seat, the female die plate and the coaming plate form a molding chamber. A plurality of pressure sensors are uniformly paved inside the male die and the female die in an interval. The output ends of the pressure sensors are successively connected with an A/D conversion module and a CPU. The output end of the CPU is connected with a 485 communication module.
Description
Technical field

Background technology
Punch process in 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 supercharging diel.Adopt Sheet Metal Forming Technology, have that precision is high, efficiency is high, quality is good, cost-saving, save the series of advantages such as material and the energy.
At present, people are more and more higher to the requirement of the precision of machine-building, and the required precision of mould is also just improved thereupon, but mould in use can produce wearing and tearing unavoidably, and the precision of processing materials itself is not high, these all can cause pressure uneven, very large on accuracy of manufacture impact.
Summary of the invention
The technical problems to be solved in the utility model is, not enough for prior art, proposes a kind of supercharging diel that can each point pressure of at-once monitor mould.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of intelligent pressure detection supercharging 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, in described punch, be shaped with for connecting the booster cavity of outer liquid force feed input, 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, in described punch and die, evenly interval is equipped with pressure sensor, the output of described pressure sensor is in series with mould/number conversion module and central processing unit successively, the output port of described central processing unit is connected with 485 communication modules.
The utility model further improves and is: the Wheatstone bridge that described pressure sensor is comprised of a piezo-resistance and three fixed value resistance forms; The input access power supply of described Wheatstone bridge; The output of described Wheatstone bridge connects described mould/number conversion module.
The utility model further improves and is: between described Wheatstone bridge and described mould/number conversion module, be in series with successively difference amplifier and low pass filter.
The utility model 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 work, immediately pinpoint the problems, and can accurately confirm problem points, via manual intervention, adjust in time, guarantee the accuracy of manufacture.
