technical field

The invention relates to the field of woodworking machinery, in particular to an improved woodworking wire saw machine.

Background technique

Wire saws, also known as straight saws, are power tools commonly used in woodworking. The principle is that the crank slide converts the rotary motion of the motor into the linear feed motion of the wire saw, so as to achieve the purpose of sawing. Compared with ordinary saw blade cutting, the wire saw of the wire saw machine is not affected by the cutting direction and cutting size, and can be cut at any angle. Therefore, it has great advantages in internal and external sawing, irregular bending processing, etc. The advantages.

In recent years, with the upsurge of traditional culture gradually rising, the market demand for antique furniture is also increasing. Traditional antique furniture manufacturing has gradually moved from pure manual work to mechanized assembly line operation. Due to the unique design and layout structure of antique furniture, The processing of the board is mainly based on internal and external arcs and irregular patterns, so this process is generally processed by a wire saw machine. The existing woodworking wire saw machines are all manually operated. The pattern lines to be processed are drawn on the surface of the board in advance, and then the board is manually sent to the workbench of the wire saw machine. Under the high-speed cutting of the wire saw, the board is slowly pushed along the pattern lines. Move until the overall cutting is completed. The disadvantages of this processing method are firstly low processing accuracy and poor repeatability, and secondary grinding is required after the plate is cut; secondly, low processing efficiency and low yield.
