Polyimide (PI) pipe cutting machine

Abstract

The invention discloses a polyimide (PI) pipe cutting machine. The PI pipe cutting machine comprises a workbench and a clamping mechanism for clamping a workpiece and driving the workpiece to rotate, the workbench is provided with a first Y-axis slideway and a base air cylinder, a base is arranged on the first Y-axis slideway in a sliding mode, an X-axis guide slot is formed in the base, at least one group of knife rest bases are installed in the X- axis guide slot in a sliding mode, each knife rest base is provided with a Y-axis electric sliding table, a knife rest is arranged on each Y-axis electric sliding table in a sliding mode, and each knife rest is provided with a blade. According to the PI pipe cutting machine, a workpiece to be cut is placed on the clamping mechanism and the workpiece to be cut is driven to rotate, the base is quickly pushed to the preset position by the base air cylinder, the blades of the knife rests are driven by the Y-axis electric sliding tables to slide to the workpiece, and the workpiece is cut into pieces. The clamping mechanism enables the workpiece not to waggle, the blades and the workpiece are always kept in a vertical state stably, the cutting size is stable, and the edges of the workpiece are neat and have no burrs after being cut.

Description

technical field [0001] The invention relates to the field of PI pipe processing equipment, in particular to a PI pipe cutting machine. Background technique [0002] PI (polyimide) tube is a new type of high temperature resistant thermosetting engineering plastic, because it can maintain high physical and mechanical properties in a wide range of temperatures from -270 to 400 ° C, and can also be used in the air at -240 to 260 ° C It is used for medium and long term, and has excellent electrical insulation, wear resistance, high temperature radiation resistance and physical and mechanical properties. There are many ways of synthesis and can be processed by various methods. Widely used in the field. In addition, PI tubes are also widely used in the outer coating of large-scale printer paper feed rollers, which require high precision for products. Traditional PI tube cutting equipment is relatively simple, and the size is not easy to adjust during the cutting process, and the e...

Problems solved by technology

In addition, PI tubes are also widely used in the outer coating of large-scale printer paper feed rollers, which require high precision for products. Traditional PI tube cutting equipment is relatively simple, and the size is not easy to adjust during the cutting process, and the edges are easy to cut unevenly. Burrs are easy to appear, and the two ends of the same PI pipe workpiece can only be cut once after being clamped. The PI pipe cannot be divided into multiple sections and cut at the same time, and the processing efficiency is very low.
