Based on the technical scheme, before the current-stage feeding and blanking die is machined, in a pre-machining area, according to the step size in the current-stage feeding and blanking die machining and the positions of the positioning pin 4 and the positioning hole 3 in the progressive blanking die, a hole through which the positioning pin 4 passes is machined in a to-be-blanked blanking metal plate 10 without a forming position. Then, during processing, the positioning pin 4 moves downwards along with the upper die, penetrates through a hole in the blanking sheet metal part 10 and is inserted into the positioning hole 3, and the mechanical positioning of the blanking sheet metal part 10 is realized as shown in a state of fig. 1.
Based on realize the location through locating pin 4 and locating hole 3 among the above-mentioned technical scheme, locating pin 4 is connected with last mould, and when the blanking metal plate spare was carried forward in the blanking mould, locating pin 4 was located blanking metal plate spare 10 top, and the blanking metal plate spare can not take place to interfere with locating pin 4, is convenient for the transport of blanking metal plate spare 10.
Based on realize the location through locating pin 4 and locating hole 3 among the above-mentioned technical scheme, locating pin 4 passes blanking metal plate spare 10, and is spacing to blanking metal plate spare 10, and in blanking metal plate spare 10 blanking forming process, locating pin 4 realizes that blanking metal plate spare 10 is spacing on the horizontal direction (mould depth direction and width direction), and the skew scheduling problem can not appear because of blanking processing in blanking metal plate spare 10, has guaranteed the location and the spacing of blanking metal plate spare 10.
Based on realize fixing a position through locating pin 4 and locating hole 3 among the above-mentioned technical scheme, when locating pin 4 inserts in blanking metal plate spare 10, can realize the fine setting and rectifying to blanking metal plate spare 10 position, realize rightting blanking metal plate spare, avoid blanking metal plate spare 10 feeding to appear the problem of position error accumulation, improve the precision of blanking processing.
Based on realize the location through locating pin 4 and locating hole 3 among the above-mentioned technical scheme, set up a plurality of along locating pin 4 and the 3 equipartitions of locating hole on the blanking metal plate part 10 direction of delivery for the location is more accurate, makes all have location and spacing on each process step of blanking metal plate part 10 blanking, avoids blanking metal plate part 10 to appear squinting scheduling problem in blanking processing.
Among this technical scheme, demountable installation has insert 8 on the pressure flitch 1, and locating pin 4 inserts 8 demountable installation with the installation, the installation of the locating pin 4 of being convenient for on the one hand, and on the other hand avoids having structural integrity, structural strength and the life who influences pressure flitch 1 with direct mount such as locating pin 4 on pressure flitch 1. Furthermore, the structure of the pressure plate 1 is simplified by adding the mounting insert 8.
In the technical scheme, in order to facilitate the installation of the positioning pin 4 and the installation insert 8, the strength of the installation insert 8 and the limiting pin is increased, the installation insert 8 is provided with the pin hole 5, the pin hole 5 comprises a large-diameter column hole and a small-diameter column hole which are coaxially arranged on the installation insert 8, and the small-diameter column hole is arranged close to the lower die 2. The positioning pin 4 comprises a large-diameter section 42 and a small-diameter section 41, and the large-diameter section 42 and the small-diameter section 41 are respectively arranged in the large-diameter column hole and the small-diameter column hole. In order to facilitate the smooth insertion of the positioning pin 4 through the blanking plate 10 and into the positioning hole 3, the end of the small-diameter section 41 remote from the large-diameter section 42 is tapered and extends out of the bottom surface of the mounting insert 8. The end part of the small-diameter section 41 is conical, so that the positioning pin 4 can conveniently penetrate through the blanking sheet metal part and be inserted into the positioning hole 3, and the position correction of the blanking sheet metal part 10 through the positioning hole 3 is realized.
In the technical scheme, the mounting insert 8 is provided with a plurality of mounting holes 6 towards the blanking plate 10 without forming positions, and two ends of each mounting hole 6 are respectively positioned on the top surface and the bottom surface of the mounting insert 8.
