As an optimized scheme of the embodiment of the invention, when the cutting unit 3 works, the Y direction of the cutting unit moves towards the linear module 27, the cutting knife 21 finishes one-time cutting on the Bar, the Z direction of the linear module 10 in the fixed knife unit 2 moves upwards to drive the cutting knife 21 to lift up, the X direction of the cutting knife 21 moves towards the linear module 28, the cutting is switched to the next position of the Bar, and the operation is continuously carried out, so that the cutting of the whole Bar is automatically finished. In addition, when cutting, through adopting rotatory mounting panel 32, can rotate Bar strip, make its other end be in the cutting station and cut, can shorten the stroke of X to linear module 28 through this structural style, avoid occupying bigger station space.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
