Description

Technical Field

[0001] The utility model relates to the technical field of strip cutting, in particular to a cutting mechanism for raw material strips. Background Art

[0002] At present, before TIG welding of raw material strips, it is necessary to cut the raw material strips through a cutting mechanism. Most of the current cutting mechanisms on the market are large in size, lack cutting power, have poor cutting compatibility for raw materials of various thicknesses and various materials, and the uneven cutting cross-section directly affects the welding process. At the same time, the manufacturing cost is high. Although a safety protection cover is installed on the current cutting mechanisms on the market, when the cutting mechanism needs to be repaired, since the safety protection cover on the cutting mechanism is fixedly installed on the cutting mechanism through a large number of bolts, when the cutting mechanism is repaired, it is necessary to first use tools such as wrenches to loosen and remove the bolts for fixing the safety protection cover before the safety protection cover can be removed, and finally the cutting mechanism can be repaired, thus reducing the convenience during the repair of the cutting mechanism.

[0036] When the safety protection cover 102 on this cutting mechanism needs to be disassembled and repaired, only need to manually rotate the rotating rod 305 upward, then move the rotating rod 305 to the right, and then rotate the rotating rod 305 downward to be stuck at the lower right part of the L-shaped limit block 306 to realize the limit of the rotating rod 305. And during the process of moving the rotating rod 305 to the right, it will drive the rectangular slider 302 and the two limiting insertion rods 303 to move to the right, so that the two limiting insertion rods 303 are respectively pulled out from the two insertion through holes 104. At this time, the safety protection cover 102 loses the limiting effect on the upper part of the tool holder 1, and then the safety protection cover 102 can be slid upward and removed, and then this cutting mechanism can be repaired.
