Description

Technical Field

[0001] The utility model belongs to the technical field of metal processing, and particularly relates to a feeding groove mechanism of a metal cutting circular sawing machine. Background Technique

[0002] At present, during the metal processing, a circular sawing machine is needed to cut metal bar stock into specified lengths for subsequent processing. The circular sawing machine uses a circular saw blade for cutting, which is different from the cutting method of the band saw blade used in a band sawing machine. When the circular saw blade cuts, it has high stability and no swing, so the surface of the cut metal material is very smooth without any burrs. During the use of the circular sawing machine, a feeding groove mechanism is required to facilitate the transportation of the metal bar stock to the lower part of the circular sawing machine for cutting work.

[0003] The existing feeding groove mechanism of a metal cutting circular sawing machine is composed of a U-shaped groove and conveying rollers. The conveying rollers are used to transport the metal bar stock inside the U-shaped groove to the lower part of the circular sawing machine. However, it has no positioning and fixing function. During the cutting process of the circular sawing machine, once the metal bar stock is not stably placed, it is easy to cause the metal bar stock to roll after cutting, resulting in friction between the metal bar stock and the side of the saw blade, which will cause the bar stock to be ejected from the U-shaped groove, increasing the danger for the staff and being not conducive to people's use.

[0004] Therefore, we provide a feeding groove mechanism of a metal cutting circular sawing machine to solve the above problems. Content of the Utility Model
