Specific embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Hereinafter implement Example is only used for clearly the technical solution of the utility model being described, and can not limit protection model of the present utility model with this Enclose.

The technical scheme that this utility model is embodied as is：

As shown in Figure 1-2, a kind of bend pipe mould, including upper die and lower die, upper mould is provided with guide pillar backing plate 2, on lower mould Guide pillar 13 position corresponding, meanwhile, limited post 6 is respectively provided with upper and lower mould.

As shown in Figure 3-4, upper mould top is cope match-plate pattern 1, and in addition to guide pillar backing plate 2 and limited post 6, cope match-plate pattern 1 is provided with Drive block 3, punch 4, convex mould pad 5 and side shield 17；Convex mould pad 5 is fixed on the center of cope match-plate pattern 1 lower section, connects under it It is connected to punch 4；Drive block 3 is arranged on the rear of punch 4, is connected on cope match-plate pattern 1, and its lower surface is a hypotenuse；As Fig. 5 institute Show, side shield 17 is connected on punch 4 one side, is inserted in the die frame 16 of lower mould.

As seen in figs. 5-6, above lower template 10 in addition to being provided with guide pillar 13 and limited post 6, it is additionally provided with locating piece 7, pushes away core 15th, spring 11 and roller 12；Locating piece 7 passes through positioning fixed plate 8 and is connected to outside lower template 10；Push away core 15 lower section and pass through push rod 9 are connect with lathe cylinders, and it is respectively arranged in the front and the rear with a pair roller 12, and the periphery of roller 12 is provided with roller fixed block 14；Push away core 15 It is arranged in die frame 16 with roller 12, be located at a line between positioning fixed plate 8 and front roller 12 in die frame 16 On upper, roller 12 and push away on core 15, it is all provided with fluted；At the rear of die frame 16, it is additionally provided with a pair of spring 11.

During work, U-tube is placed in above-mentioned groove, so that the coupling part of U-tube is located behind at roller 12, the One vertical component is located on locating piece 7；In control, mould slowly moves downward, and with lower mould closure, in this process, punch 4 connects Contact the straight line portion of U-tube, then press down in the middle of the straight line portion of U-tube, now, the first vertical component is gone up at leisure Stick up, in front roller 12 with push away and form the second corner between core 15；Second vertical component also upwarps at leisure, in rear roller 12 And push away and form the first corner between core 15, push away core 15 fovea superior slot part and slowly pushed, become mid portion, finished product such as Fig. 7 institute Show.

After completing procedure of processing, upper mould lifts, and pushes away core 15 and is lifted up in the presence of the cylinder that lower section connects, makes finished product Move up to die frame 16 upper surface, be easy to staff and take out, then carry out the processing of next U-tube.

The above is only preferred implementation of the present utility model it is noted that common skill for the art For art personnel, on the premise of without departing from this utility model know-why, some improvements and modifications can also be made, these change Enter and retouch also to should be regarded as protection domain of the present utility model.
