Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, technical scheme described in the utility model is described in further detail。
As shown in Figure 2, mould for tantalum lining plate piercing and flanging, including: upper mould 1 and the counterdie 2 matched with upper mould 1, the lower surface of upper mould 1 is provided with the die groove 11 caved inward, the bottom surface of die groove 11 is smooth plane 111, the upper surface of counterdie 2 is provided with and raises up, the flange boss 21 matched with die groove 11, the height of flange boss 21 is more than the degree of depth of die groove 11, as shown in Figure 3, when tantalum lining plate 5 is positioned in die groove 11 and after upper mould 1 and the 2-in-1 mould of counterdie, flange boss 21 and die groove 11 match the flange 52 that the surrounding of tantalum lining plate 5 can be made to be stamped and formed out enveloping tube sheet。As shown in Figure 2 and Figure 3, upper mould 1 above die groove 11 is provided with some flange through holes 13 that tantalum lining plate 5 can be made to be rushed out the heat exchanger tube through hole with flange running through mould 1, flange boss 21 is provided with the guide through hole 23 of up/down perforation counterdie 2, time actually used, tantalum lining plate 5 upwards can be punched out the work of flange by the drift rushing flange through hole 13 by guide through hole 23, makes to be rushed out the heat exchanger tube through hole with flange on tantalum lining plate 5。It addition, be additionally provided with the clamping device 3 that can make upper and lower mould 1,2-in-1 mould between upper mould 1 and counterdie 2, by regulating clamping device 3 upper mould 1 and counterdie 2 can be made close to each other or away from thus clamping or the tantalum lining plate 5 that unclamps in die groove 11。In the present embodiment, the concrete structure of described clamping device 3 is: near on the edge of mould 1 be evenly distributed with some upper installation pin-and-holes 112 running through mould 1 up and down, some lower installation pin-and-holes 22 running through counterdie 2 up and down it are evenly distributed with accordingly in the edge near counterdie 2, the lower installation pin-and-hole 22 that each upper installation pin-and-hole 112 is corresponding all interts and is provided with bolt 31, the screw rod of bolt 31 is tightened fixing by clamp nut 32 after upwards passing sequentially through lower installation pin-and-hole 22 and upper installation pin-and-hole 112, screwing or unscrew each bolt 31 can make mould 1 and counterdie 2 close to each other with nut 32 or away from thus clamping or unclamping tantalum lining plate 5, very convenient。
As shown in Figure 2, in the present embodiment, described flange through hole 13 is the through hole of interconnective cylinder successively from top to bottom and conical through hole, the through hole of cone is positioned at the lower end of flange through hole 13, and the diameter of the small-caliber end of the through hole of cone is identical with the diameter of cylindrical through hole, the heavy caliber end opening of the through hole of cone is in the bottom surface of die groove 11, so, when upwards being gone out the heat exchanger tube through hole with flange on tantalum lining plate 5 by guide through hole 23, the flange of each heat exchanger tube through hole of tantalum lining plate 5 is upwards fitted in the cone-shaped hole in each flange through hole 13 and in cylindrical hole, thus forming the flange that shape with it is identical, flange dimensional accuracy is high。In the present embodiment, the oral area sidewall of die groove 11 is provided with can place tantalum lining plate 5 shelve platform 113, as shown in Figure 3, shelve in platform 113 and after upper mould 1 and the 2-in-1 mould of counterdie when what tantalum lining plate 5 was positioned over die groove 11, the surrounding of tantalum lining plate 5 forms the flange 52 that can envelope tube sheet owing to being subject to the extruding of the sidewall of flange boss 21 and die groove 11, now, the middle part of tantalum lining plate 5 is clamped between flat surface 111 and the upper surface of flange boss 21 of die groove 11 bottom surface, it is simple to follow-up go out the heat exchanger tube through hole with flange。
The above-mentioned mold use method for tantalum lining plate piercing and flanging is as follows: is first put into by tantalum lining plate 5 and shelves in platform 113, then upper mould 1 is directed at counterdie 2 and closes up, tighten each bolt 31 and clamp nut 32 again to state as shown in Figure 2, namely tantalum lining plate 5 is held and shelves in platform 113 at die groove 11 by the flange boss 21 of counterdie 2, hereafter continue to tighten each bolt 31 and clamp nut 32 makes mould 1 and the 2-in-1 mould of counterdie, as shown in Figure 3, the effect of cooperating of flange boss 21 and die groove 11 makes the surrounding of tantalum lining plate 5 be stamped and forms the flange 52 that can envelope tube sheet, work thus completing the flange to edge, tantalum lining plate 5 surrounding。Next drift just can be used to pass through guide through hole 23 on tantalum lining plate 5, go out the heat exchanger tube through hole with flange。
The advantage of mould for tantalum lining plate piercing and flanging of said structure is in that: easy to use, difficulty of processing is little, the dimensional accuracy of the heat exchanger tube through hole that processes and flange is high。
