When the crucible is bent to the left, it collides with the first guide unit 5〇. Therefore, the present invention utilizes the main wheel die drive unit 42 to individually drive the main die 41 to rotate 'and to cause the charm wheel die 41 to be shouted to the ready state after the bend f and to drive the bend pipe by the f drive drive unit 44. The arm U drives the refreshing unit 45 and the mode drive unit 46 to perform a conversion between the first and second positions. The not only the commutation operation process is short, but the commutation (four) is fast and the productivity can be improved. It is worth mentioning that the following changes can be made in the following examples: 1. The material _ loss module 452 and the material second clamp module 454 of the cooling module 45 are merged into a common clamp module and adopt a single drive design. When the right and left V positions are prepared, the first and second straight line segments 413 and 414 are aligned with the partial area. 2 · The first mode of the cool mode drive early 46 drives the clamped single hands 462, 464 in the Y direction. The second clamping die cylinders 461, 463 are straight elements 45, and the first and second models for small size and small power are omitted, and the first and second guiding modes are omitted. 50. The above embodiment of the present invention The top pushing cylinder 25' is used to make the clamping 201130581 unit 23 move up and down in the z direction, and then cooperate with each other, so that the t« head 3〇 phase ^=;^33 and the sliding plate are displaced to achieve the conversion elbow The direction of the target 〇/α γ direction can also be designed to be 可 „ VL v direction, up and down in the Z direction, and -Y direction traverse (not shown) 勹A 1D 3 (Ϊ1~d When the η 5 hoist item 30 is in a solid state with the machine σ ίο, the hopper is traversed along the Υ direction by the feeding device 2, and the tube can also be driven. The qf hh ^ ^ 100 avoids the head 30 The components of the .4 tube device 4〇, the first guiding mold _, the second and the second guiding mold unit 兀60 can also achieve the purpose of converting the bending direction. However, the above is only the comparison of the present invention.
