Description

Technical Field

[0001] The utility model relates to the technical field of pipe shrinking machines, in particular to a pipe shrinking machine with automatic pipe feeding. Background Technique

[0002] Pipe necking is a forming process that reduces the diameter of the end of a pipe blank. When necking a pipe, a pipe shrinking machine is often used. A pipe shrinking machine is a hydraulic fully automatic pipe end processing machine that expands and shrinks the end face of a workpiece under normal conditions and is controlled by an integrated control touch display screen. By replacing the mold, the workpiece can be processed for pipe end forming such as pipe expansion, pipe shrinking, bulging, and ribbing. The processing mode can be freely determined by the user to be manual, jogging, or automatic. The machine tool consists of a fuel tank, a bed, a slider, a main oil cylinder, a die core rod (optional), a limit oil cylinder, a pressing oil cylinder, a clamping die, an axial positioning oil cylinder, an axial positioning angle iron, and other main parts;

[0003] It is found in the use of the existing pipe shrinking machine that the current pipe shrinking machine does not have the function of automatic pipe feeding. During use, the operator needs to hold the workpiece by hand and insert the workpiece inlet into the pipe shrinking machine. The pipe shrinking machine squeezes the end of the workpiece into a conical shape. After the processing is completed, the operator takes out the workpiece and then processes the next workpiece, consuming a lot of human resources and time, reducing the work efficiency, and thus resulting in poor practicability.
