Abstract

A bending radius control device for bent pipe forming comprises a fixing guiding track base, a rotating arm and a moving base which is used for fixing a pipe blank and bending the pipe blank. A sliding plate which can move along a guiding track of the fixing guiding track base is arranged on the fixing guiding track base. A limiting device for limiting the position of the sliding plate on the guiding track is arranged on the fixing guiding track base. A clamp for clamping a clamping rotating arm is hinged to the sliding plate. One end of the rotating arm is fixedly connected with the moving base. A holding opening for holding the pipe blank is formed in the moving base, and the holding opening can rotate along with the rotating arm conveniently to bend the pipe blank. The vertical distance between the hinged point of the clamp and the sliding plate and the center of the holding opening of the moving base is equal to the bending radius of the bending part of the pipe blank. When the bending radius control device is used, one end of the pipe blank is fixed, the other end of the pipe blank is clamped in the circular holding opening of the moving base, the sliding plate is fixed at a certain position of the fixing guiding track base through the limiting device, the moving base moves through external force, the pipe blank is bent into the bent pipe, and a pipe bending die is of no need.

Detailed description of the invention

As shown in Figure 1, a kind of bending radius control device for forming elbow, comprise fixed guide seat 1, turning arm 4 and the Mobile base 5 for fixing pipe and it being bent, fixed guide seat 1 is provided with the slide plate 2 that can move along its orbit of guide rail, and on fixed guide seat 1, be also provided with the stopping means that limits slide plate 2 position on orbit of guide rail, on slide plate 2, be hinged with the fixture 3 for clamping turning arm 4, one end of turning arm 4 is fixedly connected with Mobile base 5, described Mobile base 5 is provided with for accommodating pipe to pipe is carried out to bending blessing mouth with the rotation of turning arm 4, fixture 3 wants the bending radius of sweep to equate with the vertical range that the pin joint of slide plate 2 accommodates mouthful center to Mobile base 5 with pipe.

As shown in Figure 3, be vertically provided with fixed axis 9 on the upper surface of slide plate 2, fixed axis 9 is provided with can be around the column spinner of its circular-rotation 10, and described fixture 3 is fixed on the sidewall of column spinner 10; The upper surface of fixed guide seat 1 is provided with multiple screwed holes 11, and stopping means comprises two both ends of the surface that are located at respectively slide plate 2 moving directions, and the screw rod 12 being threaded with screwed hole 11; Fixture 3 is bolted to connection and is formed by two jigs, and one of them jig is fixed on the sidewall of column spinner 10.
