Cutting mechanism of rod material automatic cutting machine

Abstract

A cutting mechanism for automatic rod cutter is composed of an electric motor, cutting blades fixed to shaft of motor, a cam, a vertically moving connection rod with a top end linked to motor and a lower end in touch with said cam, a supporting block at discharge exit, a transverse bar, and a press rod with lower end connected to said transverse bar. Its advantage is correct cutting length.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to an automatic bar cutting machine, in particular to a cutting mechanism of the automatic bar cutting machine. Background technique [0002] In the process of parts processing, it is often necessary to cut a bar into several sections before processing. A cutting machine is a common processing equipment used to cut bar stock. [0003] At present, the most advanced is the automatic cutting machine. Such as the "bar automatic cutting machine with sliding positioning device" provided by Chinese patent 03271904.3, it is composed of a bed, a transmission system, a cutting system and a feeding system. To the cutting place; the bar is blocked by the stopper so that it cannot move forward; at this time, the blade on the cutting system cuts the bar through the cylinder. The efficiency of the whole cutting process is high. However, the cutting machine uses the cylinder to control the blad...

AI Technical Summary

Problems solved by technology

However, the cutting machine uses the cylinder to control the blade to move up and down to cut the bar. Although the cylinder pushes the piston rod to move up and down, although the speed is fast, there are problems of low precision and complicated equipment structure.

[0004] In addition, there is no mechanism to support the bar at the cutting point, and the bar is easy to tilt, resulting in irregular cuts and inconsistent cutting lengths
