Processing device of thin-diameter thin-wall metal elbow

Abstract

The invention discloses a processing device of a thin-diameter thin-wall metal elbow. The thin-diameter thin-wall metal elbow comprises a base, a guide wheel I, a handle, a guide wheel II and a separation blade, wherein the base is fixedly mounted on a worktable; the guide wheel I is movably mounted on the base and can rotate around the central axis of the base; the handle is mounted on the base by a movable connecting piece and can rotate left and right around the movable connecting piece; the guide wheel II is mounted in a slot arranged in the middle of the handle; the separation blade is fixed on the base and prevents a bent tubular product from radially moving in an elbow-bending process; and molded arc grooves with the same diameter as the bent tubular product are arranged on the guide wheel I and the guide wheel II along the circumferential direction and arranged on the same horizontal line. The processing device has simple structure, convenient mounting, simple and convenient use and operation and good use effect and can process various thin-diameter thin-wall metal elbows with different strength levels; and an elbow-processing process has little influence on the performance of tubular products and has convenient and flexible operation, high efficiency and low cost.

Description

technical field [0001] The invention belongs to the technical field of processing and manufacturing thin-diameter and thin-walled metal elbows, and in particular relates to a processing device for thin-diameter and thin-walled metal elbows. Background technique [0002] With the rapid development of science and technology, such as oil pipes, gas pipes, and heat pipes used in air conditioning, aerospace, and hydraulic industries, they are constantly updated. At the same time, more products need to be miniaturized, lightweight, precise, and refined. To some thin-walled special-shaped pipe fittings with small bending radius and small pipe diameter. When such parts are processed by traditional hydraulic bends, pneumatic bends, intermediate frequency bends or mechanical transmission bends, it is easy to cause various defects such as wrinkling and section distortion on the inner side of the pipe wall during the bending process, and because the pipe The small diameter and small be...

Problems solved by technology

When such parts are processed by traditional hydraulic bends, pneumatic bends, intermediate frequency bends or mechanical transmission bends, it is easy to cause various defects such as wrinkling and section distortion on the inner side of the pipe wall during the bending process, and because the pipe The small diameter and small bending radius are more likely to cause severe local deformation and large extension displacement in the bend, which will seriously thin the local wall thickness and form flat holes, cracks or cracks, resulting in extremely low yield and reduced mechanical properties. Poor appearance quality and dimensional accuracy directly affect product safety and reliability
