Description

Processing apparatus for wood

The present invention relates to a wood grooving device, and more particularly, to a wood grooving device, in which an insert groove is formed in a side surface of a wood to which a connecting member can be inserted, and a roller groove is formed on the upper and lower sides thereof. An upper groove and a lower groove machining portion which are reciprocated to the left and right by the transfer cylinder are provided on both sides of the work table so that the connecting members can be more firmly fitted to each other so that the upper groove and the lower groove of the groove can be easily processed, A plurality of grooving operations of the wood are automatically performed in a short time by simultaneously processing the roller grooves which are provided in the lower portion of the machining portion and which fix the rollers to be machined by the loading portion which is reciprocated upward, downward, leftward and rightward by the crank portion and the cylinder, To a wooden digger.

Generally, wood doors and furniture require a lot of time and manpower in cutting process such as cutting wood and grooving.

In particular, the door frame of the door has to be provided with a plurality of grooving workpieces at various places such as grooves for joining the connecting members and grooves for joining the rollers, so that the wood can be moved and processed sequentially, There is a disadvantage in that it takes a long time to process by moving the work by using the tool and the productivity is deteriorated due to this.

In order to solve such a problem, a conventional triangular grooving device of wood 20-1996-0026843 'Wooden triangular grooving device' is a device for digging triangular grooves of wood, which is composed of a wooden fixing plate for forward and backward movement by a pneumatic cylinder for fixing wood , The angled drawbar is pierced by a pneumatic cylinder for vertical digging and the isosceles wall of the triangular blemish is cut by a single lowering process. The triangular plate draw is performed by a pneumatic cylinder for horizontal digging, The triangular grooves of the triangular grooves of the triangular grooves of the triangular grooves of the triangular grooves of the triangular grooves of the triangular grooves of the triangular grooves are cut out as blowing nozzles to remove the pieces of wood And FIG.

Accordingly, the triangular-plate-type draw corresponding to the shape of the triangular bottom of the angled draw and triangular groove corresponding to the shape of the two-sided wall portion of the triangular groove formed in the wood is strongly infeeded in succession by the air pressure of the pneumatic cylinder, So that the triangular groove can be elaborately and efficiently extracted.
