Abstract

The invention relates to a calibrating method, particularly relates to an automatic calibrating method of a stamping die, and also relates to an automatic calibrating punch press employing the automatic calibrating mode at the same time. The automatic calibrating method of the stamping die is that the automatic calibration of the stamping die is achieved by correction of longitude and latitude coordinate values of a table board based on image information feedback and analysis. The automatic calibrating punch press comprises the table board, a mixer rack, a punch and the stamping die; a data collector is also fixedly arranged on the punch; the data collector is also connected with a data processor; the data processor is connected with a punch control center through a data transfer line, thus the stamping die can be automatically calibrated under different conditions; the automation of stamping production is achieved; the production efficiency is improved, and a safety accident caused by manual feeding is avoided.

Description

A kind of automatic calibrating method of diel and can calibrate punch press automatically

Technical field

The present invention relates to the automatic calibrating method of a kind of calibration steps, particularly a kind of diel, what also relate to this automatic calibrating mode of application simultaneously can calibrate punch press automatically.

Background technology

Present decompressor comprises forcing press and diel, and diel is installed on the forcing press, adopts manual feeding and manual rewinding during work; Operating personnel put into diel with punching press with cloth, utilize naked eyes that cloth is located, and drive diel by forcing press then; Diel is closed, accomplishes punch process, and diel is subsequently opened; Product after will being processed by operating personnel takes out from diel, then gets into punch process next time again.Because what this decompressor adopted is that manual feeding, manual work are located, got material by hand, so automaticity is low, production efficiency is low; And in the production process, operating personnel must stretch into hand in the mould continually, in case operate miss or decompressor break down, hand is easy to weighed wounded, and is very dangerous.

Summary of the invention

Goal of the invention of the present invention is the automatic calibrating method that a kind of diel will be provided; And can calibrate punch press automatically with the method adapts; Thereby make diel under different situations, to calibrate automatically; Realize the automation of punching production, enhance productivity, avoid the security incident that causes because of manual charging.

Goal of the invention of the present invention is achieved in that

The automatic calibrating method of said diel is to be the basis with image information feedback and analysis; Utilize the horizontal ordinate value of table top to proofread and correct the automatic calibration that realizes diel, concrete operating procedure does, at first; Diel is fit in the drift of punch press; And on table top, place calibration and use test article, start punch press, obtain the square impact product; Movable punching head is then aimed at the hollow out position that is cut with data acquisition unit, takes pictures and data are fed back to data processing centre, is just analyzing the XY coordinate figure that obtains the square impact product center and deflection angle α; And then translation drift, and with the drift rotation, cutting obtains the product that recoils; After taking down cutting products; Move tap, data acquisition unit is aimed at the hollow out position that cuts away for the second time, and data are fed back to data processing centre; The XY coordinate figure and the deflection angle α of product center of obtaining recoiling is anti-; At last, data processing centre combines the variation of square impact product center and recoil product center XY coordinate figure and deflection angle α, calibrates leading mobile vector and anglec of rotation α automatically.

The invention provides and a kind ofly can calibrate punch press automatically; Comprise table top, leading frame, drift, diel; On said drift, also be installed with data acquisition unit, said data acquisition unit also links to each other with data processor, and said data processor is connected with the data passes line with drift control centre.

Owing to adopted above-mentioned technical scheme, compared with prior art, its beneficial effect is conspicuous.At first,, install comparatively free, convenient so in the installation process of diel, need diel be fixed on the certain angle owing to utilize test article that the mobile vector and the anglec of rotation of drift are calibrated before producing.Secondly since mobile vector after will calibrating and anglec of rotation transfer of data to drift control centre; Thereby need not hand feed, locate, get material, can the automation continuous several times locate, cut, the unified material of getting; Realize the punching production automation, improved production efficiency.Last because workman do not need repeatedly charging, get material, so reduced the security incident incidence that frequent entering punch press causes.

Description of drawings

Fig. 1 is an elevation of the present invention;

When testing for the present invention, Fig. 2 obtains square impact product and recoil product respectively

Wherein 1-table top, 2-tap frame, 3-drift, 4-diel, 5-data acquisition unit, 6-data processor, 7-drift control centre, 8-square impact product, 9-recoil product, 10-preset the product that just recoiling.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is further explained.

Embodiment 1

Traditional punch press mainly comprises table top 1, leading frame 2, drift 3; On its drift 3, be a data collector 5 of non-rotating part fixed installation on drift 3 tops specifically, form new punching machine structure; Then diel 4 is fit into the bottom of the drift 3 of punch press, as shown in Figure 1.On table top 1, place calibration with test cloth, start punch press, drift 3 closures, and obtain the square impact product at test cloth, and being illustrated in figure 2 as a base angle 30 degree, waist length is 2 isosceles triangle; Movable punching head 3 then, and data acquisition unit 5 is aimed at the hollow out position that is cut, take pictures and data fed back to data processor 6, with preset square impact product comparison, analyze the XY coordinate figure (0,5) that obtains actual square impact product center A and with deflection angle α _Just=-30 degree; And then drift is moved 10 units, and with drift Rotate 180 degree, cutting obtains the product that recoils, and is as shown in Figure 2; After taking down cutting products, move tap 3, data acquisition unit is aimed at the hollow out position that cuts away for the second time, and data are fed back to data processor 6, the XY coordinate figure B (0,15) and the deflection angle α of the product center that obtains recoiling _Instead=-30 degree; At last, data processor 6 combines the variation of square impact product center and recoil product center XY coordinate figure and deflection angle α, calibrates leading mobile vector and anglec of rotation α automatically; Obtain: rotation (30 degree)--punching press--playback----upset 150 degree--punching press that moves horizontally 1 unit; Such drift moves, rotate instruction, and this instruction generates in drift control centre 7, and control drift 3 moves automatically, location, punching press.

Embodiment 2

When diel was comparatively complicated irregular mould, because change is bigger, so before obtaining instruction, repeatedly, repeatedly the displacement and the anglec of rotation are calibrated, generate at last that drift moves, rotate instruction, other each operation was like embodiment 1.
