Description

[Detailed explanation of the invention] [Industrial application field] This invention is based on
Regarding the planer used when machining caulking grooves on ALC plates, it is a particularly useful tool when constructing thin ALC plates.

[Conventional technology]

Conventionally, the sides of ALC plates with a thickness of 50 mm or less were made waterproof by butting them together without applying any tenon processing or the like, and then filling the surface of the joint with caulking material. In other words, the long side of the ALC plate is shipped after chamfering the corners on the front side and forming a box-shaped groove for filling with caulking material.
When joining the long side of an ALC plate cut widthwise on site, or joining the short side of a sheet shipped without grooves, do you just chamfer it on site and fill it with caulking material? Alternatively, box-shaped grooves were manually dug and filled with caulking material, and a dedicated groove-making tool had not been developed, making it difficult to perform complete waterproof caulking. .

[The problem that the idea aims to solve]

The purpose of the present invention is to provide a planer for machining caulking grooves that can be easily used at construction sites. A chamfering plane is used to process the circumferential surface of the ALC plate, but if you finish planing the ALC in the same way as planing wood, if the ALC itself is easily chipped, it is often difficult to finish the planing. There is a fear of chipping in some parts, which would result in a defective product, so instead of cutting all the way to the edges, a back plane is used to prevent chipping. If you are simply chamfering, you can use the same planer, but if you are creating a groove with a special shape as described in this invention,
You cannot use a return planer with a regular planer unless you use another planer with a different blade direction.

Therefore, in the present invention, a return plane can be used for making such grooves with a single plane.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention has a planer stand equipped with two orthogonal planer surfaces, and one of the planer surfaces has a cut that can be entered and exited perpendicularly to the planer surface for cutting the end face of a square groove. A pair of caulking groove machining blades, the cutting blade being inclined in the longitudinal direction of the planer surface that cuts the surface outside of the cutting edge and which can be moved in and out, are placed in such a way that the cutting blade is in front of the cutting blade. This is an ALC version of the caulking groove machining planer configured so that two pairs are provided on the same planer surface so that the planer can be planed in opposite directions.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. Figure 1 is a front view of one embodiment of the planer of the present invention, Figure 2 is its top view, Figure 3 is its right side view, Figure 4 is an explanatory diagram of the cutting surface of the ALC to be processed,
FIG. 5a shows a cutting blade, FIG. 5b shows an example of a cutting blade retainer and cutting blade, and FIG. 6 shows another embodiment of the present invention.

Reference numeral 1 denotes a planer table made of iron plate, which has two planing surfaces that are orthogonal to each other. It is expanding in the direction. Reference numeral 5 indicates a mounting base for the cutting blade, and reference numeral 6 indicates a hole drilled in the plane surface for protruding the blade, both of which are provided on one plane surface 2. The mounting base 5 for the cutting blade has a U-shaped side cross section. It is welded and fixed to the back surface of the planer surface 2 of the planer table 1 at an angle. 7 is a cutting blade, 8 is a long hole provided in the cutting blade, and the cutting blade 7 can be taken in and out by sliding along the inside of guides 9 provided on both sides of the upper surface of the mounting base 5 in the width direction. , nut 1 fixed to the back side of the mounting base 5
The cutting blade 7 can be fixed at a desired position by passing the butterfly screw 11 through the elongated hole 8 and screwing the blade 11 through the long hole 8.

Reference numeral 21 denotes a cutting blade mounting base provided on the back side of the planer table 1 perpendicularly to the same planer surface 2, 22 is a cutting blade, and the cutting blade mounting base 21 is equipped with guides 23 for the cutting blade on both sides. In addition, the cutting blade 22 can be slid up and down. Reference numeral 24 denotes a cutting blade fixing metal fitting, which is fixed in the middle of the cutting blade mounting base 21 so as to embrace the mounting base.
The cutting blade 22 can be fixed by pressing the cutting blade retainer 25 interposed between the cutting blade fixing fitting 24 and the cutting blade fixing fitting 24. The cutting blade 22 has a thin blade shape, is parallel to the other plane surface 3, and is cut along the end surface of the cutting blade 7 on the opposite side to the other plane surface 3.
It is becoming more prominent. As this cutting blade 22, a commercially available spare blade of a cutter knife can be used.

The cutting blade 7 and the cutting blade 22 described above constitute a pair of caulking groove machining blades, and the cutting blade is provided so as to precede the cutting blade.

In this embodiment, as shown in FIGS. 1 and 2, two pairs of caulking groove machining blades are provided on the same planer surface so that they can cut in opposite directions, and the two cutting blades 7, 7 , are oriented toward each other inward when viewed from the side.

Further, in this embodiment, a cutting blade 22' is provided between the cutting blade 7 and the cutting blade 22 preceding it, and the cutting blade 22' preceding the cutting blade 7' is provided in the opposite direction. The position of ' may be reversed.

In the one shown in FIG. 6, the positions of the two pairs of processing blades are different, and the two cutting blades 7, 7' are provided so as to face each other outward when viewed from the side.

Next, how to use the planer of the present invention will be explained.

As shown in Fig. 4a, the caulking groove connects the joining surface 33 of the ALC plates 31 and 32 to the square groove 34 at the bottom.
It is constructed by processing so as to have an outwardly opening groove 35 at the upper part thereof, and the plate end portion 36 is chamfered in advance to form an inclined surface 37.

Next, the plane surface 2 of the plane according to the present invention is
The planer surface 3 is placed on the side surface 33 of the ALC plate so that it is in contact with the ALC plate surface 38, and in the case of the planer of the embodiment shown in FIG.
Then, the cutting blade 22 is projected to the desired position, the pair of processing blades 7' and 22' on the left side are retracted, and the planer surface is turned toward the other side of the page of FIG. 4b.
When planing is carried out from one end of the ALC plate, a notch 39 is cut by the leading cutting blade 22, and then a surface 40 is shaved by the cutting blade 7 to form half of the square groove 34.

Planing starts from one end of the ALC version, but
If you continue to planer all the way to the other end, there is a high possibility that chips will appear at the end of the planer. When the blade 22' and the cutting blade 7' are made to protrude, the pair of processing blades on the right side are retracted, and the planer is pulled toward the front of the page in Figure 4b,
A square groove formed by surfaces 39 and 40 can be formed. You can therefore plan from each opposite end of the ALC plate with one planer.

In the example planer shown in FIG. 6, when moving the planer to the right in the figure to form a cutting surface with the working blades 7 and 22 on the right half, the cutting edge 7' of the left half blade has already been cut. Since the surface is simply stroked in the opposite direction, and the cutting blade 22' simply follows the trajectory of the surface that has already been cut, there is no need to take the blade in and out each time when hanging the planer in the opposite direction. .

〔effect〕

As explained in detail above, if you use the ALC caulking groove machining planer of the present invention, you can create caulking grooves of the same shape with one planer, but you can plan from opposite directions. Accurately create caulking grooves in the desired shape without causing any chipping or requiring skill.
Since it can be easily formed, it greatly contributes to improving the efficiency of on-site construction, especially for thin ALC plates.
