Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cutting devices, and more specifically, to a cutting device for lock production. Background Art
[0002] The padlock is provided with a lock beam. At present, when the lock beam is produced, the straight rod is generally bent into a U-shaped rod first, and then the U-shaped rod is installed on the workbench. The two straight segments of the U-shaped rod are cut by a cutting device respectively, and the cutting positions of the two straight segments are different. When the existing cutting device cuts the U-shaped rod, it is generally only provided with one cutting tool. The position of the cutting tool is first adjusted to cut one of the straight segments of the U-shaped rod, and then the position of the cutting tool is adjusted to cut the other straight segment. When this method adjusts the cutting tool, the position accuracy is high. When the position accuracy is offset, the cutting position will change, reducing the cutting accuracy. In addition, when the U-shaped rod is cut, it is easy to be subjected to force, causing its position to change, which in turn causes the cutting position to change. Utility Model Content
