Abstract
The utility model relates to a stretching mold with multi-stage positioning. The technical scheme includes that a fixing plate is connected between an upper template and a matrix, a blank holder matched with the matrix is connected onto an ejecting rod, the ejecting rod is in sliding fit with a lower template, and a punch matched with the matrix is seated at the upper end of the lower template. More than two sets of positioning pins are arranged on a pressure surface of the blank holder, the lower ends of the positioning pins extend into the blank holder, the upper ends of the positioning pins extend out of the pressure surface of the blank holder, the lower ends of the positioning pins are elastically abutted to the inside of the blank holder, the positioning pins are positioned on circumferences centering at the center of the blank holder, the positioning pins of the same set are arranged on a circumference with the same diameter, and the diameters of the circumferences of the positioning pins in different sets are different. The stretching mold with multi-stage positioning has reasonable structure, is suitable for metal plates with a plurality of sizes, consequently, greatly lowers mold cost, requires no frequent replacement of positioning parts when in use, and is capable of improving production efficiency.
Description
Technical field
The utility model relates to drawing die, specifically a kind of drawing die that sheet metal is drawn into tubular.
Background technology
Existing a kind of mould basic structure that sheet metal is drawn into tubular is: be connected with fixed head between cope match-plate pattern and the die, blank holder with taking a seat and match with die in the push rod upper end that lower bolster is slidingly matched is connected with the punch that cooperates with die on the lower bolster.The shortcoming that existing this drawing die in use exists is: need the location on the blank holder because sheet metal is placed on, when processing the sheet metal of each different size, need be on blank holder the centring ring of suit correspondence, when the size of the sheet metal that is stretched changes, then need to change centring ring, every tackling mould need be equipped with many cover centring rings, such side makes the cost of mould increase greatly, when second the size of sheet metal changes, changing centring ring needs lost time, influences production efficiency.
The utility model content
The purpose of this utility model is to provide a kind of multistage location drawing die, and this drawing die need not be equipped with centring ring, still can be to the sheet metal location of multiple size.
For achieving the above object, the utility model adopts following scheme: multistage location drawing die, be connected with fixed head between cope match-plate pattern and the die, the blank holder of taking a seat and match with die in the push rod upper end that is slidingly matched with lower bolster, be connected with the punch that cooperates with die on the lower bolster, be furnished with two groups of above alignment pins on the pressure-bearing surface of blank holder, the alignment pin lower end is stretched in blank holder, the pressure-bearing surface of blank holder is stretched out in the upper end, the lower end of alignment pin and the inner elastomeric of blank holder against, the center that alignment pin is in blank holder is on the circumference in the center of circle, each alignment pin on the same group is on the circumference of same diameter, and each organizes the diameter difference of the residing circumference of alignment pin.
By such scheme as seen, but owing to be extended with the alignment pin of some groups of elastic telescopics on the pressure-bearing surface of blank holder, can be by every group of alignment pin to the sheet metal location of different size, and at die, when both pressure-bearing surfaces of blank holder clamp sheet metal, alignment pin can be retracted in the blank holder, can not influence die and cooperate with the normal of blank holder.
The utility model is rational in infrastructure, and it can adapt to the sheet metal of multiple size, and then the cost of mould is descended greatly, and it does not in use need frequently to change positioning element, and production efficiency can be improved.
Description of drawings
The structural representation of Fig. 1 the utility model one embodiment;
The vertical view of blank holder among Fig. 2 Fig. 1.
The specific embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Referring to Fig. 1, Fig. 2
In the multistage location drawing die that the utility model provides, be connected with fixed head 2 between cope match-plate pattern 1 and the die 3, the blank holder 4 with taking a seat and match with die 3 in push rod 5 upper ends that lower bolster 7 is slidingly matched is connected with the punch 6 that cooperates with die 3 on the lower bolster 7.Be furnished with two groups of above alignment pins 8 on the pressure-bearing surface of blank holder 4, the pressure-bearing surface that alignment pin 8 lower ends are stretched in blank holder 4, blank holder 4 is stretched out in the upper end, the center that alignment pin 8 is in blank holder 4 is on the circumference in the center of circle, each alignment pin 8 on the same group is on the circumference of same diameter, and each organizes the diameter difference of alignment pin 8 residing circumference.
Referring to Fig. 1
The inner elastomeric of the lower end of alignment pin 8 and blank holder 4 against mode be: have through hole 4a on blank holder 4, screw 10 is equipped with in the bottom of through hole 4a, and spring 9 is housed in the through hole 4a, and alignment pin 8 is landed on the spring 9.
Referring to Fig. 2
In conjunction with Fig. 1, Fig. 2 as seen, when processed sheet metal suits by a certain group of alignment pin 8 location, sheet metal is placed on a certain group of alignment pin 8 inboards, can carries out stretch process sheet metal.For example, when the suitable one group of alignment pin 8 by innermost layer of processed sheet metal is located, sheet metal is placed on this group alignment pin 8 inboards; When processed sheet metal suits by outermost one group of alignment pin 8 location, then sheet metal is placed on this group alignment pin inboard, and when this situation, sheet metal is landed in other and respectively organizes on the alignment pin 8.In addition, when carrying out stretch process after die, both pressure-bearing surfaces of blank holder clamp sheet metal, alignment pin 8 can be retracted in the blank holder, can not influence die and cooperate with the normal of blank holder.
