Automatic pipe bending machine for spiral pipe

Abstract

The invention provides an automatic pipe bending machine for a spiral pipe, and relates to the technical field of machining. A pan bottom burning black scale removing device based on automatic cleaning comprises a fixing frame, one side of the other end of a fixing plate is fixedly connected with a fixing column, one side of a fixing arm is fixedly connected with an air cylinder, and the output end of the air cylinder is fixedly connected with a spiral pressing plate. A steel pipe is fixed to the end of a spiral groove of a spiral pipe bending die through a spiral pressing piece, the spiral pipe bending die is rotated to drive the steel pipe to rotate, the steel pipe forms a spiral pipe shape around the spiral groove in the spiral pipe bending die, a third forward and reverse rotation motor rotates forwards to enable a third sliding block to move, a rotating motor is started at the same time, and the spiral pipe is separated from the spiral pipe bending die. A cutting motor drives a cutting blade to separate the spiral pipe from the non-spiral steel pipe, one-time coiling of the steel pipe is completed, the spiral distance of the manufactured coiled pipe is good in consistency, the pipe is not prone to deformation in the pipe bending process, the labor intensity of operators is low, the working efficiency is greatly improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of machining technology, in particular to an automatic pipe bending machine for spiral pipes. Background technique [0002] The coiled tube used in the automobile pipeline system is in a spiral coiled state, and is made of stainless steel tube. The diameter of the stainless steel tube is Φ15~Φ18mm, the wall thickness is 1.5mm, and the number of spiral turns of the coiled tube is 7. [0003] The automatic pipe bending machine currently used cannot realize the bending and forming of this spiral pipe. The stainless steel pipe can only be bent into a spiral pipe by using the pipe bending fixture manually. The helical pitch of the formed coiled tubes has poor consistency, and usually three operators can work together to complete the processing of 50-60 coiled tubes in one day, and the labor intensity of the operators is high, the work efficiency is low, and the production cost is high.
