Abstract
The utility model relates to a hand-operated core pulling pipe bender. A horizontal worm gear speed reducer driven by a hand wheel is arranged below a worktable, a main shaft of a worm gear of the horizontal worm gear speed reducer is connected with a pipe bending die drive shaft through a coupling, and a pipe bending die is mounted in a manner of penetrating the plane of the worktable. When a pipe is bent, a core pulling head, a positioning pin, a core pulling rod, a bearing, a core pulling and adjusting wheel are correspondingly mounted, the core pulling rod is sleeved on a core pulling support, and the neck of a core pulling head is aligned with the center line of the pipe bending die by rotating the core pulling and adjusting wheel. A steel pipe needing arc bending is pushed from the core pulling head, the position of starting arc bending of the steel pipe is aligned with the central line position of the pipe bending die, a pipe clamp and a pipe clamp fixing clip are used to fix the steel pipe on the pipe bending die, and an adjusting rod presses a tensioning wheel to enable the steel pipe to be propped against the pipe bending die. A worm rod is driven by the hand wheel to rotate a worm wheel, a linkage section, a pipe bending die transmission shaft and the pipe bending die, and then the pipe bends to form an arc; and since the core pulling head and the core pulling rod are clamped on the core pulling support, the core pulling head in the pipe can not move along with the steel pipe, and the bending pipe can be molded perfectly.
