Abstract
The utility model relates to a continuous stamping die set for producing aluminum sheet deep-drawing products. The continuous stamping die set for producing aluminum sheet products comprises a raised grain wavy formed punching head as a starting punching head, a deep-drawing punching head and a punching head. The raised grain is composed of at least two concentric circular rings. An additional drawing straight punching head and a flange punching head can be used for stamping the fins of a heat exchanger. The stamping die set can finish the internal material feeding for once. Compared with a traditional die set, the procedure is reduced. The utility model has strong adaptability for aluminum sheets. The product produced by the utility model has no breach or frying opening, and the surface finish is high.
Description
The utility model relates to the diel group that is used to produce aluminium sheet pull and stretch goods, particularly relates to the continuous stamping die group of producing heat-exchanger fin.
The punching press of existing aluminium sheet pull and stretch goods, for example heat-exchanger fin generally all is directly aluminium sheet to be carried out pull and stretch, and for fear of breach occurring, needing nearly, 6-7 time pull and stretch repeatedly just can be pulled to desired height.This not only causes the pressing equipment complexity, and expends man-hour.In addition, it is also very high to the ductility requirement of aluminium sheet, and accommodation is little.
The purpose of this utility model is the shortcoming that overcomes above-mentioned prior art, a kind of continuous stamping die group that is used to produce aluminium sheet pull and stretch goods is provided, this set of molds is pulled out feed thereby can once be finished by inside, to satisfy the needs of aluminium sheet pull and stretch by at first aluminium sheet being imposed ripple glaze fluctuating moulding.
The continuous stamping die group of aluminium sheet pull and stretch goods of the present utility model comprises drawing formed punch, and pierce punch, the initial drift that it is characterized in that continuous punching press are ripple glaze fluctuating moulding drifts, and this ripple glaze is made of at least two concentric circles.
Diel group of the present utility model can also comprise pulling out and fling head that the flange drift is used to make heat-exchanger fin.
Fig. 1 is the side cutaway view of diel group of the present utility model;
Fig. 2 is the profile of the ripple glaze fluctuating moulding drift among Fig. 1;
Fig. 3 is the vertical view of the ripple glaze fluctuating moulding drift among Fig. 1;
Below with reference to accompanying drawing the utility model is elaborated.
As shown in Figure 1, diel group 1 of the present utility model is except comprising drawing formed punch 2, pierce punch 3, and key is to have increased ripple glaze fluctuating forming punching head 4 as initial drift. Referring to Fig. 2 and Fig. 3, ripple glaze fluctuating forming punching head comprise symmetrical upper punch and Low punch, ripple glaze is made of a plurality of donuts 5, and its quantity is 2-10. The protruding section of each of ripple glaze is semicircle and isosceles trapezoid is joined, and height of projection h is 1-1.8mm, is preferably 1.4mm, and the semicircle radius R is 0.65-0.75mm, and the base angle of isosceles trapezoid is 68 °-75 °. The diameter phi of the center circle 6 of ripple glaze fluctuating drift0〉=3mm can strengthen as required. Diameter phi by each outside ripple glaze donut 5 of center circle 6nFor:
φ
n＝φ
0＋n△φ
Wherein diameter increment △ φ=4.5-7.5mm, be preferably 6mm
n＝1、2、3……10
According to diel group 1 of the present utility model, by ripple glaze fluctuating moulding drift 4, at first aluminium sheet is washed into ripple glaze, can all pull out the material in the area of a circle of all energy feeds of aluminium sheet once thus, for the usefulness of follow-up drawing sequence.By regulating the number of ripple glaze donut simply, can satisfy the demand of different pull and stretch height, and need not to increase extra stamping procedure, the scope of pull and stretch height is 1-10mm.
According to the utility model, on the basis of ripple glaze fluctuating moulding drift 4, drawing formed punch 2, pierce punch 3, additional pulling out flings 7 and flange drift 8, promptly can be used for the stamped of heat-exchanger fin.
Embodiment
The diel group comprises ripple glaze fluctuating moulding drift 4, two drawing formed punch 2, pierce punches 3, pull out and fling 7 and flange drift 8.
The technical parameter of ripple glaze fluctuating moulding drift is as follows:
The diameter phi of center circle 6
0=14mm
The number of donut 5 is 6
The diameter increment △ φ=6mm of donut 5
Ripple glaze height of projection h=1.4mm
Projection semicircle radius R=0.65mm
Isosceles trapezoid base angle=72 °
Through the continuous punching press of above-mentioned six drifts, can be in diameter be the circle of 50mm feed, pull out the fin of high 8mm.
Diel of the present utility model has the following advantages:
1, can once finish internally feeding, reduce the 4-5 procedure.
2, simplify equipment, shortened man-hour.
3, the adaptive faculty to aluminium sheet is strong, need not to increase extra operation.
4, easy to the adjusting of drawing height, need not to increase extra operation.
5, less demanding to Deep Drawing Lubrication oil, even can adopt machine tool lubrication liquid (saponification liquor), get final product, with low cost.
