Description of the invention (1) [Invention of the present invention is a pipe machine, especially the upper pipe bending mechanism wheel, and a curved handpiece, the bending die wheel and combination, so that two-phase movable die wheel and pipe bending operation shape The kind of abutting radius with different curvatures above a single size (the previous technology such as the eleventh on the two sides of the movable wheel (2 4)) is equipped with transmission, (2 7) points 1) and curved mobile phones, (2 7 1) When it moves, it can just work. Among them, there is a solid technical field on both the left and the side.] As for a kind of adjustable finger, the sliding mode in its structure corresponds to the required change or radius of movement of the mold wheel. There is an adjustment shaft 2 that does not move outward (the template I of 2 is deflected. The two right-handed fixed molds of the two ends are seated in the groove of the shaft block of the double-bend drive shaft. The bending radius of the curved hand crank mechanism with the mold wheel is offset or the angle of the left and right slide seat of the double bender; and the left and 5) are driven by the yaw, 6), (2 (2 6 2) left and right The crank is turned upward (2 6 (28)), and the tube bending machine can be adjusted by using a set of tube bending machine, and then it is used as the center of the bending group. The guide push on the supporting structure of the supporting shaft group is bent semi-variantly and the wheel can be changed to change the left and right sides of the machine. The setting is provided by the force of the workpiece and the diameter varies; It is easy to construct a 0-turn right-slide movable mold. Bend die wheel This eccentric end can be made into two kinds (2 ), On the machine (2 1) (22), (2 3) the right and left slides (2 2), (2 3 left and right crank mechanism (26) make the workpiece use the main mold wheel (2 5 7) The sliders (2 6 1) and (2 7 2) are clamped and the mechanism (2 6), (2 7) are folded to achieve the required pipe bending operation), (2 7) the corresponding inner cylinder (281) Drive clip

Page 5 200417429 V. Description of the invention (2) The die (2 8 2) can be used as a two-point clamp to fix the workpiece with the fixed template (2 8 3); the slider I 2 .3 1), (2 1) The movements of the adjustment rods C 2 6 3) and (273) are moved up and down to match the main i-die (2 5 1) of different diameters to clamp and guide the workpiece to form curved pipes with different radii, and use the adjustment wheel (24) The relative positions and distances of the left and right slides (22), (2 3) can be adjusted by the rotation, so as to adapt to the bending operation of the two ends of the workpieces of different lengths. The model wheel (2 5 1) has a flat section (2 5 2) on the outside, and its mandrel (2 5 3) is also connected with a power source for driving, so that the flat section (2 5 2) can be turned to one side for snapping in The workpiece in the groove of the main mold wheel (2 5 1) can be taken out by β ejection; and for different bend radii, a main mold wheel (2 5 1) with a different diameter must be separately provided. According to the pipe bending operation and pipe structure of the conventional # pipe machine, it is known that there are many disadvantages in practical use, such as: ① No matter the radius of the pipe, a master die must be made for each size. The ratio of the production cost to the daily operation cost is quite high, and the cost is not high, which also increases the usual management costs. ② At the time of pipe bending, at least a considerable size must be reserved at the front end for clamping the main die wheel and the bending die, so the finished product will leave this section of straight tube. For workpieces that do not need this section of straight tube, it must be cut off separately, which is troublesome. Increase costs. φ ③ The guide mold and the image guide mold are used to clamp and hold the workpiece. The workpiece is pushed forward by the feeder. Its port is completely directly hard rubbed, which can easily damage the surface of the pipe or produce serious scratches. ④ For pipe bending operations at two angles, such as when the first and second arcs are at 90 ° or other angles, the machine must stop and restart when bending the second arc.
