Detailed Description

The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.

Examples, see fig. 1-3: a front material ejecting mechanism on a bar material cutting machine comprises an outer frame 10, a supporting plate 11, a lifting oil cylinder 12, a material cutting oil cylinder 13, a push rod 14 and a fixed seat 15, wherein the outer frame 10 is of a hollow structure with two through end faces, the material cutting oil cylinder 13 and the supporting plate 11 are both positioned in the outer frame 10, and the supporting plate 11 can transversely move in the outer frame 10 after being stressed. The support plate 11 has a front cutter positioning portion for positioning a front cutter, and the outer frame 10 has a rear cutter positioning portion for positioning a rear cutter, the front cutter and the rear cutter being arranged in a scissors-type intersection. A certain impact gap is formed between the material cutting oil cylinder 13 and the supporting plate 11, and after the bar materials are positioned, an oil cylinder rod of the material cutting oil cylinder 13 collides with the impact supporting plate 11 to drive the front cutter to move and be matched with the rear cutter to cut the bar materials.
