Description

Double-cutter bidirectional wood lathe

Technical Field

The utility model relates to a wood lathe's technical improvement, especially a two-way wood lathe of double knives.

Background

Along with the improvement of living standard of people, the requirements on furniture and home decoration articles are continuously improved. Because the curved shape of the wooden product increases the visual aesthetic feeling, the hand feeling is good, the grade is high, and the wooden product is more and more favored by people. Solid-of-revolution wooden products such as furniture legs, bed head accessories, clothes hangers, pen holders, Roman uprights of wooden stairs and the like are mostly processed through a wood lathe. During machining, a workpiece is clamped in the chuck or supported between two tops of the main shaft and the tail frame, and the workpiece is driven by the motor to rotate. The turning tool is arranged on a tool rest, and is moved by a slide carriage belt to perform longitudinal or transverse feeding motion, or the turning tool can be held by hands to lean against a bracket to perform processing such as excircle, end face, grooving, boring and the like of a workpiece, and then the workpiece is polished and painted. The product processed by the numerical control lathe has good quality, accurate size and high efficiency, can be produced in batches, but has high equipment cost and is difficult to popularize. Wooden products machined by a common wood lathe are difficult to ensure in size and finish degree, the working efficiency is low, and further polishing is needed after turning, so that batch production is not easy to form. Simple manual lathe machining requires an operator to hold a turning tool to feed against a carriage to cut a rotating blank. The size can only be sensed by naked eyes, and errors are easy to occur. In particular, when a plurality of products having the same shape and size are manufactured, errors are more likely to occur.
