Stamp for drawing body parts
(57) Abstract:
The invention relates to a sheet punching and tin can exist used in all branches of applied science cartoon sheet material presses on simple and double action. The inventive stamp for cartoon torso parts contains the punch, the matrix pertainym threshold and pertainym edge and clamp with grooves under pertaini threshold and puritaine edge. Puritaine edge placed straight backside pertainym threshold without a gap between them and thereby puritaine edge becomes a continuation preteenage threshold. When the hood body parts in the die width and the mass of the technological allowance going after trimming the waste decreases, thereby decreasing the dimensions of the sheet and the saving of canvas metal. two Il.
The invention relates to a sail punching and tin can be used for drawing of diverse sheet materials.
The predominant area of its application extractor presses on simple and double action torso parts of cars, tractors and home appliances.
Known standard design exhaust stamp containing the punch, the known postage has insufficient braking bringing the flange of the workpiece slips into the opening in the matrix that practice not provide for extension of the Central part and causes the excessive metal.
To reduce the size of the workpiece is used preteenie thresholds mainly for extraction of shallow parts with a smooth contour.
The disadvantages of the use of pertainig thresholds should include inability smooth and in a wide range of regulation of the tension of the workpiece in the process of deformation that does not allow the hood without defects for parts rather complicated grade.
Also known stamp for hoods [2] contains the punch, blank holder and die with pertainym threshold and pertainym edge, and puritaine edge located in the area preteenage threshold.
This design allows y'all to create intense tension of the metal and to adjust the degree of tension in the procedure of drawing.
The disadvantage of this postage is the excess metal on the technological allowance, as for reasons of strength matrix width threshold is called significantly more (approximately 3 times) traditional 12-15 mm [1]
Known for superior design of the stamp to the hood body is them with recesses under pertaini threshold and puritaine edge. In the famous stamp puritaine edge made for pertainym threshold with a gap between them.
This allows you to go some savings metal in comparing with analogues for stamping parts rather simple course. However, in this postage procurement should have increased the size that its edges advocated puritaine border. At the concluding moment of drawing the flange of the workpiece remains on permainan the threshold and, equally a rule, permainan border and has overestimated the width. This technological allowance is removed afterwards trimming the waste, which results in excessive metal in the hood body parts of complex shape and a deep hood.
Notwithstanding, in the described structures of the postage cannot be eliminated, removing a significant portion of the workpiece in the waste, which leads to a high consumption charge per unit of sheet metal on the detail.
To obtain a saving of sheet steel is used stamp, where puritaine edge is installed directly behind pertainym threshold without a gap between them and thereby puritaine edge is a continuation preteenage threshold.
The invention consists in that the stamp for drawing body parts, containing the punch, the matrix ethnoi threshold and puritaine border puritaine edge placed direct backside pertainym threshold without a gap between them and is a continuation preteenage threshold.
This blueprint implementation takes into account the fact that the width and weight of technological allowance going after trimming the waste decreases, thereby decreasing the dimensions of the sheet and the saving of sail metal under the hood of a specified body parts.
In Fig. 1 shows a cross section of the seal for hoods with pertainym threshold in the form of a U-shaped protrusion and pertainym edge placed for pertainym threshold without a gap and which is a continuation preteenage threshold; Fig. 2 is a department of the stamp in the area preteenage threshold.
Stamp for drawing body parts (Fig. 2) contains the punch i, matrix 2 with pertainym threshold iii in the form of a U-shaped protrusion and the clench four with pertainym edge v.
Press double activity stamp works as follows. Sail workpiece is placed on the clamping surface of the matrix 2. Further, when the course outside of the press slide down the edge of the barracks is deformed and is pressed by the clamp four, and the workpiece is drawn into the gap Z between pertainym rib v and the recess in the clamp 4. The ZAT is drawing the border of the barracks moves through pertaini threshold 3 pinnacle H1and puritaine rib v, which is pertaini threshold 3 value of Ntwo. Inhibition of the workpiece when moving through pertaini threshold 3 and puritaine rib 5 is regulated mainly by changing the values of H1and H2established past calculation and adjusted when debugging this stamp to extract specific details.
Ingather technology allowance that remains after extraction semi-finished product 6, by line 7.
On a similar scheme operates stamp for cartoon body parts with successive pertainym threshold and edge on the press simple steps.
STAMP FOR DRAWING BODY PARTS, containing the punch, the matrix pertainym threshold and pertainym rib, located behind pertainym threshold and clench with grooves under preteenie threshold and border, characterized in that puritaine edge placed directly backside pertainym threshold without a gap between them and is a continuation preteenage threshold.
