Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of wood chisel processing, and particularly relates to an automatic wood chisel production line and method. BACKGROUND

[0002] The traditional wood chisel production mode is multi-piece processing, and the processing equipment is a large plane grinding machine. Each face of the wood chisel needs to be placed on a workbench by a worker for grinding. The seven faces of the wood chisel are divided into four grinding processes, which are grinding of side faces, grinding of large faces, grinding of inclined edges and grinding of blade edges. The multi-piece processing mode makes the labor intensity of the workers very high and time-consuming and labor-consuming. Since four grinding processes are required, a large number of turnovers and semi-finished products are increased, resulting in a very long production cycle, and the wood chisel is easy to rust in the production process.

[0003] Therefore, a new technical scheme is needed to solve the above technical problems. SUMMARY
