Abstract

This invention relates to a pipe bending machine capable of bending a pipe to left and right. The pipe bending machine includes a table, a rotary clamping device disposed on the table, and a pipe bending device moveable along the table. The rotary clamping device clamps and positions the pipe as well as adjusts the phase of the pipe properly. The pipe bending device performs unsymmetrical bending at either side of the rotary clamping device to operate in coordination with the pipe clamped by the rotary clamping device. Thereby, by cooperation of the rotary clamping device and the pipe bending device, the both ends of the pipe can be bent unsymmetrically. Furthermore, one pipe bending device can be eliminated to save the cost.

Description

1265059 IX. Description of the Invention: [Technical Field] The present invention relates to a pipe bending device, and more particularly to a function of bending asymmetrical three-dimensional shape at both ends of an official member and having a left-right bending function. Bender. [Prior Art] As shown in Fig. 1 and Fig. 2, there is a conventional bending machine (the Patent Application No. 92105312 of the Republic of China), which includes a machine i and a fixed machine on the machine! The intermediate fixed mold bases 2 and 2 are respectively provided on the curved heads 3 on both sides of the fixed mold base 2. The fixed mold base 2 has a fixed clamp block 2〇1 and a movable clamp block 202 which can be engaged with the fixed heat block 201I to clamp the tubular member. The pipe bending heads 3 each have a movable die wheel 3〇1, a crank mechanism 302 that can be rotated relative to the 3H movable die wheel 301, and a crank handle mechanism 302 that is disposed on the crank mechanism 312. The movable die wheel 3 is an eccentrically disposed bending wheel 303. When the middle portion of the pipe member is positioned by the fixed die holder 2, the two ends are also held between the movable die wheel 3〇1 of the pipe bending head 3 and the bending die wheel 3〇3, and the crank hand is driven. When the mechanism 302 swings and drives the bending wheel 3〇3 to swing relative to the movable wheel 301, the pipe can be bent at both ends. Although the pipe bending machine can bend the pipe fittings, because in the bow s, the ahai fixed die base 2 is only clamped to the pipe fittings, so only the pipe fittings extending in the same plane (two degrees) can be bent out. . Further, as shown in Fig. 3, another type of pipe bending machine (U.S. Patent No. 4,843,861) includes a rotary holding device 4 disposed in the middle and two bending device 5 disposed on both sides of the rotary holding device 4. As shown in FIG. 4 , FIG. 5 and FIG. 6 , the rotating holding device 4 has a housing 401 and a power unit 402 mounted inside the housing 401 , a transmission unit 403 , a brake unit 404 , and a brake unit 404 . A driving unit 405 for driving the brake unit 404, a fastening unit 406 and an idler unit 407. The transmission unit 403 and the brake unit 404 each have an internal gear 403, 404, and two external gears 403", 404" disposed on the outer gears 403, 4, 4, and the fastening unit 406 also has a An inner pinch wheel 408 that engages with the inner gears 403', 404' and an outer pinch wheel 409 that can be coupled with the outer gears 403", 404". The inner pinch wheel 408 has an inner clamping surface 408 inside. The outer pin wheel 409 has an outer clamping surface 4〇9 disposed eccentrically with respect to the inner clamping surface 408'. When a motor 4〇5 of the driving unit 405 is activated, the internal gear 4〇4 of the braking unit 4〇4 can be braked, and the inner clamping wheel 4〇8 of the fastening unit 4〇6 is also generated. Positioning, and when the power unit 402 inputs power, and using the transmission unit 4〇3 and the external gears 403”, 404” of the brake unit 404, the outer clamping wheel 4〇9 of the fastening unit 4〇6 is interlocked with respect to the inner clamp. When the wheel 4〇8 is eccentrically rotated, the outer clamping surface 409' is eccentrically rotated to engage the inner clamping surface 4〇8 to clamp a tube. When the brake is released, the outer clamping wheel 409 can drive the inner clamping wheel 4〇8 and the pipe to rotate together to achieve the purpose of adjusting the phase. Although the rotary clamping device 4 of the bending machine can position the pipe clamp, the phase adjustment can be performed between the secondary bending operations to achieve the purpose of the three-dimensional bending. However, the overall structure of the pipe bender and the rotating clamping device 4 still have the following disadvantages: - The movable range of the pipe device 5 is bounded by the rotating clamping device 6 1265059, and is synchronized. Symmetrical bending of the two ends of the pipe is not suitable for pipe processing with asymmetrical ends. ^ First, when adjusting the phase, the inner clamping wheel 408 is not directly driven by the power 402#, but is passively dragged due to the frictional force of the pipe fitting, which is liable to cause the pipe to loose. Second, the composition of many components, will cause the overall volume is large, for some light clips
