FILM CUTTING APPARATUS FOR RADIOGRAPHIC TESTING OF A HEAT EXCHANGER TUBE WELD AND METHOD THEREOF

摘要

The present invention relates to a film cutting apparatus and method for radiographic inspection for easily cutting the film used for radiographic inspection according to the application, and more particularly, the film used in the radiographic inspection of the heat exchanger tube welding portion In addition to cutting to length, the work is carried out in a single operation by implementing a series of procedures for cutting corners (chamfering) required for the characteristics of heat exchanger tube welds and for drilling holes for incoming / outgoing radiation sources required for radiography. It is an object of the present invention to provide a film cutting apparatus and method for radiographic inspection of heat exchanger tube welds, which can be performed quickly and conveniently to improve working efficiency. The present invention for achieving the above object is a cutting device for cutting the radiographic inspection film of the heat exchanger tube welding portion, pedestal; A support frame installed to face the pedestal; A rotary shaft rotatably installed at both ends of the support frame; An operation lever for rotating the rotary shaft; A cam unit provided in the rotary shaft and converting the rotary motion of the rotary shaft into a linear motion; A cutting assembly receiving linear movement of the cam unit and performing linear movement on the pedestal; And it provides a cutting device for cutting the film for the radiographic inspection of the heat exchanger tube welding part including a film cutting support plate provided on the pedestal facing the cutting assembly.
