Description

Technical Field

[0001] The utility model belongs to the field of feed cutting devices, in particular to a feed cutting device for a bolt setting machine. Background Art

[0002] The manufacturing process of bolts includes annealing, pickling, wire drawing, and forming. The bolt former is a high-performance forging equipment that can produce hundreds of bolts per minute by shearing and plastic processing coiled materials. Bolts with various shapes can be obtained by using bolt formers with different structural characteristics. Coiled materials are usually bundles of steel wires, which are fed into the bolt former for forging through a feeding device used in conjunction with the bolt former. In actual industrial production, bundles of steel wires will automatically bend during transportation due to their own structural strength. In order to facilitate the bolt former to cut and forge the steel wires, the steel wires must enter the bolt former straightly. Therefore, the feeding device will correct the bent steel wires so that they enter the bolt former straightly.

[0003] The Chinese patent with the announcement number CN208913068U discloses a feed cutting device for a bolt setting machine, which is used in the field of mechanical basic parts and their manufacturing technology, and includes a workbench and a cutting wheel for cutting steel wire, and also includes a cutting frame for mounting the cutting wheel, the cutting frame includes a fixed base frame and a movable frame hinged on the fixed base frame, a cutting motor is mounted on the movable frame, and the cutting wheel is rotatably mounted on the movable frame and fixedly connected to the output shaft of the cutting motor. It has the technical effect of being able to cut the unusable curved section at the end of the steel wire, thereby ensuring the quality of the bolts forged by the bolt setting machine, while the feed cutting device of the bolt setting machine in the application has multiple adjustment components that can only be adjusted individually, and the adjustment efficiency is slow.
