Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment: with reference to Fig. 2, a kind of flanging die of high leakproofness, including mold 2 and lower template 3,3 sets of lower template On rubber membrane 13, the flange of 13 port of rubber membrane falls in the upper surface of lower template 3, and mold 2 is turned over 13 port of rubber membrane The upper surface on side, mold 2 and lower template 3 clamp, so that 13 port sealing of rubber membrane is dead.
With reference to Fig. 2, several clamping screws 31 are set in lower template 3, several mounting holes 22 are processed on mold 2;Locking screw Bolt 31 is circumferential to be evenly arranged in lower template 3, and mounting hole 22 is also circumferential to be evenly arranged on mold 2, and clamping screw 31 and mounting hole 22 correspond.Clamping screw 31 passes through mounting hole 22, is then locked together mold 2 and lower template 3 with nut.
Referring to figs. 2 and 3, it is symmetrical arranged two positioning pins 32 in lower template 3, location hole 23, positioning are set on mold 2 Hole 23 is corresponding with positioning pin 32.23 lower end of location hole is big, is inserted into convenient for positioning pin 32;Upper end is small, for matching with positioning pin 32 It closes, plays positioning action.
With reference to Fig. 2, in assembling process, positioning pin 32 is inserted into location hole 23, so that mold 2 and lower template 3 are first fixed Mold 2 and lower template 3 are locked together by position then by passing through the clamping screw 31 in mounting hole 22.
With reference to Fig. 4, setting is used for the handle 5 of carrying mould body 2 on mold 2, is cased with spacer 51 on handle 5.Handle 5 is just In carrying mould body 2, the moving hand of 51 effective protection of spacer is not galled by handle 5.
With reference to Fig. 4 and Fig. 5,2 lower end surface of mold processes cone boss 21, opens up cone-shaped inner hole 33, taper in lower template 3 The inclined outer wall of boss 21 is matched with the conical inboard wall of cone-shaped inner hole 33, in the inclined outer wall and taper of cone boss 21 When the conical inboard wall in hole 33 matches, rubber membrane 13(is referred into Fig. 2) it clamps, rubber membrane 13(is played with reference to the water in Fig. 2) The effect of sealing for the first time.
With reference to Fig. 4 and Fig. 5, several jagged first fins 41,3 upper end of lower template are also processed on 2 lower end surface of mold Face processes several the second fins 42 matched with the first fin 41 of 2 lower end surface of mold.
Referring to figs. 2 and 5, the first fin 41 and the second fin 42 form biting connecions folder to the flange of 13 port of rubber membrane It holds, by reducing the contact area with the flange of 13 port of rubber membrane, so that the case where rubber membrane 13 is by an equal amount of power Under, the deformation quantity of rubber membrane 13 is big, so that the gap between rubber membrane 13 and the mold is smaller, to promote high flanging die Leakproofness.
With reference to Fig. 6 and Fig. 7,3 lower end surface of lower template processes groove 35, installation sealing ring 36 in groove 35, in lower template 3 Sealing ring 36 ensure that the leakproofness between the flanging die of high leakproofness and steel lining multiple tube 1 is good.The section of groove 35 at Inverted trapezoidal, the section of sealing ring 36 is at hourglass shape.Sealing ring 36 is stuck in groove 35, effectively prevent sealing ring 36 from groove 35 In fall off.
With reference to Fig. 6, several circumferentially uniformly distributed through-holes 34, the flange on through-hole 34 and steel lining multiple tube 1 are processed in lower template 3 Several connecting holes 141 on circle 14 are corresponding, and bolt passes through the connecting hole 141 on the through-hole 34 and flange circle 14 of lower template 3, use Lower template 3 is fixed on flange circle 14 by nut, by the water seal in rubber membrane 13 and rubber membrane 13 in steel lining multiple tube 1.
Operating procedure summary: first by 3 sets of lower template on rubber membrane 13, lower template 3 is fixed on steel with screw bolt and nut On the flange circle for serving as a contrast multiple tube 1.Handle 5 is caught to navigate to mold 2 in lower template 3 by positioning pin 32, tightening nut will Mold 2 is fixedly connected with lower template 3.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in the scope of the claims of the utility model.
