Description
Technical field
What the present invention relates to is the joint method that a kind of plug-in type dovetail joint engages casing and plug-in type dovetail joint thereof, is applicable to box-type furniture, casing furniture etc., belongs to material and production of articles technical field.
Background technique
In casing class Furniture manufacturing process, usually need some to have good, the easy processing of intensity, standardization, structural stability, beautiful decoration, convenient installation, and do not affect the connected structure of furniture functions and outward appearance.The connected structure of casing class furniture is all the conjunction of employing joggle usually, hardware engages and glueds joint and closes etc., and wherein joggle is the widest with splicing application area.In existing a few class joggles, the applying frequency of machine-processed stopped dovetail in casing furniture is the highest, and machinery production reduces difficulty of processing on the one hand, improves manufacturing efficiency; On the other hand, although machine-processed stopped dovetail is not so good as full impregnated dovetail joint in intensity, it has passed on the joint outward appearance of traditional semi-transparent dovetail joint very well.
Utilize dovetail joint tenoning machine can process full impregnated tenon and half through tenon, full impregnated tenon needs to process the sheet material connected respectively, easy to process not as half through tenon, so industrial production is applied less; Pole tenon and sheet tenon can meet standardization batch production, but bond strength is more weak; The colored tenon template of being produced by LEIGH company can process diversified semi-transparent Tenon moulding, although decorative effect is extremely strong, Curve Machining is more in process of production, causes occurring larger bonding error, and reduces manufacturing efficiency.
For the connected structure of various casing furniture, high, the easy processing of its demand fulfillment intensity, indeformable, convenient, good stability be installed, the requirement such as can be mass.At present, various joint method emerges in an endless stream, and is widely used in furniture industry, but, up to now, yet there are no and utilize plug-in type dovetail joint to engage sheet material, and be applied in casing furniture.
Summary of the invention
What the present invention proposed is the joint method that a kind of plug-in type dovetail joint engages casing and plug-in type dovetail joint, its objective is by plug-in type dovetail joint joint sheet material, to be applicable to make housing structure furniture.
Technical solution of the present invention: plug-in type dovetail joint engages casing, and it is characterized in that one group of Symmetry Edge of sheet material 1 is cut sth. askew except base angle end by saw, there is multiple tongue-and-groove 3 in front, inclined-plane 2, is plug-in type dovetail joint 4 in tongue-and-groove 3; It can be divided into reassembling type and non-reassembling type.
Plug-in type dovetail joint engages the joint method of casing, and its feature comprises the steps:
1) cut sth. askew by the base angle end of one group of Symmetry Edge of n block sheet material 1 saw and remove, form inclined-plane 2, angle of inclination in the horizontal plane, inclined-plane 2 forms by the angle of inclination excision adjusting saw blade;
2) two groups of inclined-plane 2 alignment are fixed on after being adjacent to and mix up on the backer of angle;
3) adjust track template, mill out multiple tongue-and-groove 3 along rail flanges from left to right with dovetail joint milling cutter;
4) as being non-reassembling type, can on inclined-plane 2, tongue-and-groove 3 and dovetail joint 4 coating binder 5;
5) inclined-plane 2 of n sheet material 1 is alignd between two be adjacent to again;
6) (or driving in) tongue-and-groove 3 is inserted by dovetail joint 4;
7) adopt manual binding clasp to compress and make plug-in type dovetail joint casing.
Advantage of the present invention: make owing to inserting dovetail groove with the oblique side of the monomer dovetail joint of standardized production and compressing, can be made into polygonal bins moulding, meets different angle and obtains casing making requirement; Ensure dimensionally stable, effectively reduce the damage that expand with wet and contract with dry brings; Processing is simple, and tenon can mass, standardized production; There is higher mechanical strength and bearing capacity; Can be made into multiple dovetail flower tenon, play good decorative effect.
