[0019] In order to make the technical means, creation features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.
[0020] Please refer to Figure 1 、 Figure 2 The utility model provides a novel elbow pipe machine's upper and lower die clamping structure technical scheme:
[0021] Upper die 1, lower die 2, and the clamping of the elbow pipe is carried out between the two, so that the elbow pipe is clamped;Upper die 1, lower die 2 are all rotationally connected on rack 4;
[0022] Fixing assembly, including slide rail 63, push block 62, first driving part 61;The first driving part 61 pushes push block 62, and push block 62 moves in slide rail 63;The first driving part 61 is air cylinder.
[0023] Clamping structure 3, including upper key block 31 and lower key block 32;The upper key block 31, lower key block 32 correspond to upper die 1, lower die 2 respectively, and correspond to insert;
[0024] The clamping structure 3 is installed on a rotating support 5, and the rotating support 5 rotates along the rack 4, so that the elbow pipe is bent.
[0025] The upper die 1 bottom has a recess, for clamping with the convex part of lower die 2.
