Large-curvature small-curvature one-time forming device for pipes

Abstract

The invention relates to the technical field of pipe machining, and discloses a large-curvature small-curvature one-time forming device for pipes. The device comprises a mounting plate, a cover shellis fixedly connected to the top of the mounting plate, a power box is fixedly connected to the bottom of the mounting plate, a motor which is vertically arranged is fixedly connected to the inner bottom of the power box, an output shaft of the motor is located at the upper end of the motor, and the tail end of the output shaft of the motor is fixedly connected with a rotating rod in a sleeved modethrough a coupler; and the rotating rod penetrates through the side wall of the mounting plate and extends into the interior of the cover shell, the rotating rod is rotationally connected with the mounting plate, a push-bending die is fixedly connected to the top of the rotating rod, a fixing block corresponding to the push-bending die is fixedly connected to the inner top of the cover shell, oneside, close to the push-bending die, of the fixing block is provided with a gear groove, and the inner wall of the gear groove is rotationally connected with two fixed roller wheels corresponding tothe push-bending die through bearings. According to the large-curvature small-curvature one-time forming device for the pipes, large-curvature forming and small-curvature forming of the pipes can be completed without replacing machining equipment and a machining process.

Description

technical field [0001] The invention relates to the technical field of pipe processing, in particular to a large-curvature and small-curvature one-time forming device for pipes. Background technique [0002] In the traditional production of bent pipe fittings, based on two-dimensional product drawings, hot bending with sand filling, tailor welding, manual cold bending with sand filling, ordinary machine bending, and hydraulic bending of steel pipes are used. The traditional pipe bending completely relies on the operator's experience and technical proficiency to control the product quality, and there are many processes and the operation process is complicated. The tube shape of its products is quite different, the amount of correction is large, the labor intensity is high, it is difficult to form mass production, and the bending quality of large-diameter tubes is difficult to guarantee, and problems such as out-of-tolerance dimensions and wrinkles at the inner radius often oc...
