Arc-shaped saw for cutting arc-shaped wood

Abstract

The invention relates to the technical field of wood cutting machine tools, in particular to an arc-shaped saw for cutting arc-shaped wood. The arc-shaped saw comprises a saw belt which is tensioned through a lower driving wheel and an upper driving wheel, a follow-up corner mechanism is arranged at the two ends of a cutting action end of the saw belt in a sleeving manner and comprises an upper rotating drum and a lower rotating seat, an upper saw belt clamping roller and a lower saw belt clamping roller are fixed in the upper rotating drum and the lower rotating seat respectively, and a lower chain wheel is arranged at the bottom of the upper rotating drum in a sleeving mode. The lower chain wheel is connected with a servo driving mechanism through a chain, the upper rotating drum and the lower rotating seat synchronously rotate through an arranged linkage mechanism, a servo sliding supporting plate used for clamping plates is arranged on the front portion of the cutting action section, and the servo sliding supporting plate and the servo driving mechanism are electrically connected with a numerical control system. The servo driving mechanism drives the follow-up corner mechanism to rotate, so that the width direction of the saw belt is always tangent to a curved knife edge, the accuracy of a cutting arc is ensured, meanwhile, unnecessary friction of the saw belt is avoided, and the service life of the saw belt is prolonged.

Description

technical field [0001] The invention relates to the technical field of wood cutting machine tools, in particular to an arc saw for arc wood cutting. Background technique [0002] The arc or curve cutting of existing wood panels is mostly done manually on the jigsaw. However, manually controlling the direction of the panel on the jigsaw is not only labor-intensive, but also the curves produced are poor in precision, beautiful and consistent. It is difficult to guarantee the safety, it is not safe, and it needs time-consuming grinding; now there are also CNC machine tools that use a cutting knife with a certain diameter to perform curved cutting in the form of milling slots, but this processing method has a large blade width, and the wood does not Not fully utilized, resulting in a great waste of wood.

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide an arc saw for cutting arc-shaped wood in view of the technical problems mentioned above. The linkage between the moving corner mechanism and the servo sliding pallet realizes the cutting of wood arcs, which solves the problems of labor-intensive manual cutting, poor precision, and large cutting edges caused by ordinary CNC machine tools, which cause wood waste.
