Vertical stripping processing technology for manufacturing seamless thin wall pipe

Abstract

The invention discloses a vertical stripping processing technology for manufacturing a seamless thin wall pipe, comprising the following steps: a. a machine tool with a perpendicular mold core column is prepared to be arranged; b. a thin wall plate is paved on the top of the mold core column; and c. through a perpendicular relative movement between a stripping roller and the mold core column, the thin wall plate is stripped. Three stripping rollers are provided, which are averagely distributed according to the circumference of the mold core column. In the process of stripping, the mold core column drives the thin wall plate continuously to turn; and the turning direction at every time is opposite to the rotation direction in the process of stripping at a former time. Cooling liquid is continuously splashed in the process of stripping. After the process of stripping, the manufactured thin wall pipe is processed by means of annealing and distressing. The mold core column is perpendicularly positioned instead of being transversely positioned previously; the thin wall plate is not needed to be processed into cap-shaped semi-finished products but directly into the desired thin wall pipe at one time; and the processing quality of the thin wall pipe can not be influenced by the function of the gravity.

Description

Technical field: [0001] The invention relates to a rolling process for producing seamless thin-walled pipes. Background technique: [0002] The printing quality of printing equipment such as printers, copiers and fax machines depends largely on the wall thickness of internal thin-walled pipes (including fixing rollers, developing rollers, etc.), which require efficient thermal conductivity and Heat resistance, which requires the thickness of the thin-walled pipe to be as thin as possible. The current processing technology is to first carry out a deep drawing process on the thin-walled sheet to process a cap-shaped semi-finished product, such as figure 1 As shown, then put the hat-shaped semi-finished product on the mold core column placed horizontally, and clamp the brim of the hat at the same time. During processing, the roller moves back and forth from side to side, and at the same time, the mold core column drives the hat-shaped semi-finished product to rotate continuousl...

Problems solved by technology

Due to this process, the core column is placed horizontally during processing, and the thin-walled tube is prone to eccentricity due to the influence of gravity during the forming process, resulting in poor wall thickness uniformity, cylindricality, and smoothness, which affects the printing equipment. print quality
