Abstract

A method is used for manufacturing a floor at an interface between neighboring two parts on a large blank (101). The blank (101) is cut firstly on the front face with a saw (104), then is cut secondly on the opposite side with the saw (104), and the first and second saw kerf are cut through at the interface between neighboring two parts. Thus neighboring two parts are separated. As cutting on the front face and the opposite side of the blank successively, and a head of the saw (104) being sharp-angled or gradient configuration, the width of the blank (101) cut off is less than the thickness of the saw (104) at the position where the kerfs are cut through. Therefore, the loss of kerf is reduced.

Description

Description A method for processing a lock floor

Technical field

[1] The present invention relates to a floor processing method, and more particularly to a method of processing a lock floor.

Background technique

[2] Flooring is increasingly favored as a material for decorating interior floors. Current flooring is generally formed by splicing of smaller strips of floorboard, of which the locker floor is more commonly used. The lock floor has the characteristics of easy installation, no need for cementation, and re-disassembly, making it one of the main products in flooring products in recent years. The latching structure of the locking floor includes a tongue and groove respectively formed on opposite sides of the floorboard. After paving the floor, the tongue of a piece of floorboard is snapped into the groove of the adjacent floorboard to form a lock fit. Repeating this way, the plurality of floorboards can be joined into pieces to form a floor close to the overall effect. When it is necessary to disassemble the cymbal, the tongue of a floorboard can be removed from the gutter of the adjacent floorboard.

[3] In the processing of floor slabs, large slabs must first be cut into multiple floor slabs according to the required dimensions of the floor slab.

As shown in FIG. 1 and FIG. 2, in the prior art, the saw blade 102 is directly cut, and each time the saw blade is directly penetrated, the processing method has obvious sawing loss, and each sawing is generated. The sawing surface 103 has a thickness greater than the thickness of the saw blade, so that at least one sheet thickness of the saw blade is lost. After cutting the floor blank, the corresponding groove or tongue is milled by the milling cutter around the floor blank; because the flat cutting surface is formed during the cutting process, there is no subsequent processing of the groove or tongue Special benefits. Summary of the invention

[4] In view of the above-mentioned drawbacks of the prior art, the present invention solves the problem that a direct through-cutting method in a conventional floor processing method causes a large sawing loss, and provides a floor processing method capable of reducing sawing loss.

[5] The solution to the above technical problem is to provide a floor processing method, which comprises the following steps: (1) Floor blank cutting: for the boundary of two adjacent floor blanks on a large-area slab, with a saw The knife saws the first knife on the front side and the second knife on the back side, and the sawing path of the first knife and the second knife penetrates each other at the boundary of the two adjacent floor blanks to thereby connect the two adjacent blocks Separating the floor blanks, the head of the saw blade is a pointed or inclined structure, and the thickness of the sheet sawed in the through position is smaller than the thickness of the saw blade; (2) Machining of the gutter or tongue: Milling the tongue or tongue at the edge of the cut floor blank with a milling cutter.

[6] In the present invention, when the boundary edges of the two adjacent floor blanks are all processed into tongue-and-grooves, or both are processed into tongue-and-grooves, the head of the saw blade is preferably a center-symmetric sharp-angled structure; The sawing paths of the first knife and the second knife have the same center line, and the inner sharp corner formed by the first sawing road and the inner sharp corner formed by the second sawing road are mutually at the boundary between the two adjacent floor blanks Through.

[7] In the present invention, when the boundary edges of the two adjacent floor blanks are processed into a tongue and groove, and the other is processed into a tongue and groove, the head of the saw blade is preferably an inclined structure; The center line of the saw blade and the center line of the second saw road are parallel to each other and the distance between the two is equal to or slightly smaller than the thickness of the saw blade; the first saw blade forms an internal inclined angle head and the second saw The head of the internal inclined angle formed by the road penetrates the boundary between the two adjacent floor blanks.

[8] In the present invention, the inclined structure of the saw blade head may be a stepped inclined structure or an integral inclined structure.

[9] In the present invention, the sawing depths of the first blade and the second blade are preferably equal to or slightly larger than one-half of the thickness of the floor blank.

[10] It can be seen from the above scheme that in the solution of the present invention, since the squeegee is cut twice, and the head of the saw blade is pointed or inclined, the thickness of the sheet is sawed at the through position. It will be smaller than the thickness of the saw blade, so that the sawing loss can be reduced. In addition, the corresponding saw blade can be selected according to the groove or tongue to be processed on the edge of the floor blank, on the one hand, the sawing loss is reduced, and on the other hand, according to the groove or The shape of the tongue is cut out during the sawing process to reduce the amount of work during the processing of the gutter or tongue.

detailed description

A preferred embodiment of the present invention is shown in Figs. 3a to 3f, in which a process of cutting with a saw blade having a stepped inclined structure is shown.

[20] Figure 3a is a large area slab before cutting.

[21] In Fig. 3b, the saw is cut using a stepped inclined saw blade 104, the first knife is sawed on the front side, and the saw blade is taken out to obtain the structure shown in Fig. 3c. The drawings of the various embodiments of the present invention are simplified cross-sectional views, in particular, wherein the saw blade is a disc-shaped electric saw blade with a stepped inclined structure as shown. For the convenience of description in the present invention, the edge of the saw blade is expressed as the head of the saw blade according to the effect of the cross-sectional view.

[22] In Fig. 3d, the second knife is sawed on the back side, and the structure shown in Fig. 3e is obtained after the saw blade is taken out.

[23] Figure 3f shows the secondary processing of the hoe and gutter structure, with the left side being the hoe and the right side being the grooving.

[24] As can be seen from Fig. 3a to Fig. 3f, the sawing depths of the first knife and the second knife are equal, and both are slightly larger than one-half of the thickness of the floor blank; the sawing path of the first knife and the second knife The two adjacent floor blanks are mutually penetrated at the boundary of the two adjacent floor blanks 101 to separate the two adjacent floor blanks. Since the head of the saw blade has an inclined structure, the thickness of the sheet material cut at the through position is smaller than that of the saw blade 104. Thickness, correspondingly significantly reduces sawing loss

[25] In Figures 4 to 8, the sawing losses produced by different cutting methods are shown. For the convenience of illustration, the edge structure of the formed floor is drawn, that is, the complete boring head and the grooving structure; as shown in Fig. 3a to Fig. 3f in the actual processing, the boring head and the grooving structure are cut first and then processed. .

[26] In Fig. 4, the saw blade 104 is a stepped inclined structure having a thickness of 32 (actually 3.2 mm, the figure is an effect of magnifying ten times, as shown in Fig. 5, Fig. 6, Fig. 7, Fig. 8 below) The data is also magnified ten times.) As can be seen from the figure, the left side of the first knife is on the same line as the right side of the second knife, indicating that the center line of the first saw road and the center line of the second saw road are mutually Parallel, and the distance between the two is equal to the thickness of the saw blade; the lower edge of the first knife and the upper edge of the second knife are in the same straight line, indicating the sawing depth of the first knife and the second knife Equal, and equal to one-half of the thickness of the floor blank. As can be seen from the figure, the distance between the edges of the boring head and the gutter structure to be obtained is 20, which is 12 less than the thickness of the saw blade. Compared to conventional machining methods, each cut saves 12 turns of sawing loss. In addition, the cutting positions of the first and second knives correspond to the boring and grooving structures to be processed, which can reduce the work during the processing of the grooving and tongue

[27] In Fig. 5, the saw blade 105 is an overall inclined structure having a thickness of 32. It can be seen from the figure that the center line of the first sawing road and the center line of the second sawing road are parallel to each other, and the distance between the two is slightly smaller than the thickness of the saw blade; the sawing depths of the first knife and the second knife are equal And are slightly larger than one-half of the thickness of the floor blank; the distance between the edge of the boring head and the groove structure to be obtained is 20.65, which is 11.35 smaller than the thickness of the saw blade, which means that the thickness can be saved by 11.35 per cutting. The sawing road is lost.

[28] FIG. 6 shows the sawing loss by the conventional processing method for the case where the edges of the two adjacent floor blanks are all processed into the boring head, wherein the saw blade 102 has a thickness of 32, and the cutting boring penetrates the entire large-area slab. It can be seen from the figure that the thickness of the sheet cut between the upper corners of the two boring heads obtained after the final machining is completed is 68.2.

[29] FIG. 7 shows the sawing loss using the method of the present invention, and the same is true for the case where the edges of two adjacent floor blanks are processed into hoes, and the sharp-edged saw blade 106 shown in the drawing is used. For the front and back cuts twice, the thickness of the saw blade is still 32. The thickness of the cut sheet between the upper corners of the two boring heads obtained after the final processing is 52, which can be reduced by 16.2 compared with Fig. 6. Saw road loss.

[30] Compared with Fig. 7, the saw blade 107 in Fig. 8 is sharper, the thickness of the saw blade is still 32, and the thickness of the sheet cut between the upper corners of the two boring heads obtained after the final processing is 39.02, compared with Figure 6, can reduce the sawing loss of 29.18.

[31] As can be seen from the above specific embodiment, in the present invention, since the crucible is cut twice, and the head of the saw blade is sharp or inclined, the thickness of the sheet is sawed at the through position. It will be smaller than the thickness of the saw blade, so that the sawing loss can be reduced. In addition, the corresponding saw blade can be selected according to the groove or tongue to be processed on the edge of the floor blank, on the one hand, the sawing loss is reduced, and on the other hand, according to the groove or The shape of the tongue is cut out during the sawing process to reduce the amount of work during the processing of the gutter or tongue.
