[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for manufacturing a spiral laminated material, such as a spiral stair spar, a spiral slide, and the like.

[0002]

2. Description of the Related Art Conventionally, a method of manufacturing a laminated material formed into a spiral shape is a method in which a plurality of laminated members are closely attached to a cylindrical body or a clamping mold having a predetermined curvature at a predetermined spiral inclination angle, and are stacked and pressed. It is press-formed with a clamping plate block.
(See, for example, Japanese Patent Application Laid-Open No. 7-251402)

[0003]

In the production of the conventional spiral laminated material, if the curvature changes, a new cylindrical body or a press-clamp is required, which causes an increase in cost. In the case of laminating a large number of members, it is necessary to align the end faces in the width direction of the members to be laminated, to prevent the members to be laminated from being lifted by the pressing force for molding, and to adjust the shape to be the reference of the spiral shape. For this purpose, it is necessary to apply pressure to align the end faces in the width direction of the laminated members on radiation passing through the center of the radius of curvature of the predetermined cylinder or the clamping die, but this is difficult with the conventional method, and the design is difficult. There was a problem that it was difficult to obtain a spiral spiral laminated material.

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus for easily and inexpensively manufacturing a helical laminated material into a designed shape simply and inexpensively.

[0005]

In order to achieve the above object, a rectangular frame clamping apparatus according to claim 1 having the same shape.
An apparatus for manufacturing a helical laminate according to claim 2 using a plurality of tools has been invented. The vertical frame of the square frame clamping device is attached a ruler plate and TateKa platens can be adjusted to any height.

[0006] On the ruler plate, a receiving platen which receives a vertical pressure and keeps a helical inclination angle constant, and a horizontal direction plate comprising a horizontally movable platen and a movable platen for forming a spiral press. A pressure clamping device is installed. The vertical pressing plate and the receiving plate on the ruler plate are mounted at positions where the pressing surface is in line contact pressure. The platen of the pressing device is shaped to be in line contact pressure.

[0007] By applying the vertical pressure to the line contact pressure on the radiation passing through the center of the designed radius of curvature, the width direction of the members to be laminated can be aligned to prevent floating, and the designed spiral inclination angle can be easily obtained. . The horizontal change of the horizontal clamping device can be used to change the curvature, and if there is an excess or deficiency, the rectangular frame clamping device can be easily moved, and a new cylinder or clamping mold is unnecessary and inexpensive. Can be manufactured.

[0008] The spiral laminated material can be easily and inexpensively manufactured into a designed shape by using a plurality of square frame fasteners according to the present invention. In the manufacture of a spiral laminated material, a plurality of square frame pressing members are arranged so that the pressing surface, which is in line contact with the surface plate, is positioned on the designed curvature and on the radiation passing through the center of the designed radius of curvature. The pressing line of the vertical pressing is arranged on the radiation passing through the center of the designed radius of curvature.

This work is to determine the reference positions of the vertical frame and the ruler board of the square frame clamping device and to attach a scale to each of them. The pressing line of the platen and the pressing line of the vertical pressing are square frame.
It can be easily made by machining so that it becomes the center of the thickness of the pressing tool , and a spiral laminated material as designed can be manufactured more accurately. The scale of the vertical frame is effective for positioning the receiving platen mounted on the ruler plate when setting the helical inclination angle, and the scale on the ruler plate facilitates installation of the platen on the design curvature. Pressurized pressure lines of the receiving plate than that which coincides with the center of the thickness of the square frame clamping device, receiving can be easily installed pressurized pressure curve of the surface plate on the radiation passing through the center of the design radius of curvature.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings based on embodiments. However, the drawings are for explanation only, and do not limit the scope of the present invention.

FIG. 1 illustrates the production of a helical laminate according to the present invention using a plurality of square frame fasteners . FIG.
Shows a plan view thereof. Figure 3 ruler Release 4 and TateKa platen 5 in the rectangle frame clamping device 2 shown in the adjustment of the height in rectangle frame clamping device can be fixed at an arbitrary position can be freely. The pressing line of the vertical pressing plate 5 and the pressing line of the receiving platen 6 on the ruler plate 4 are aligned at the center of the thickness of the square frame pressing tool .
The platen 7 and the movable platen 8, which press the ruler plate 4 in the horizontal direction, can move in the horizontal direction and can be fixed at any position. A pair of vertical frames 3 of the rectangular frame clamp 2 are provided with scales 3a for facilitating the positioning of the ruler board 4. The ruler plate 4 is provided with a scale 4a for facilitating the positioning of the platen 7.

FIG. 4 is a front view of a rectangular frame clamping device in which members to be laminated are clamped. The pressure line of the platen 7 on the ruler plate 4 is arranged so as to be located on the design radius of curvature 10.
The pressing line of the receiving platen 6 and the vertical pressing plate 5 on the ruler plate 4 is arranged so as to be located on the radiation 9 passing through the center of the designed radius of curvature 10. The pressing line of the surface plate 7 and the pressing line of the vertical pressing intersect on the radiation 9 passing through the center of the design radius of curvature 10. Thus, all the pressure surfaces are in line contact pressure. 5 and 6 supplement this description. The member 1 to be laminated is placed on a receiving platen 6 on a ruler plate 4, pressurized by a vertical pressing plate 5, and pressed and formed by a movable platen 8. By applying pressure from the widthwise end face of the members 1 to be laminated by the vertical pressing plate 5, irregularities in the width direction can be eliminated, and the members 1 to be laminated due to lateral pressure can be prevented from floating. The receiving platen 6 is pressed by the vertical pressing plate 5 on the radiation 9 passing through the center of the designed radius of curvature by line contact, so that the helical inclination angle is as designed. A helical laminated material as designed can be manufactured by forming the surface plate 7 in which the horizontal pressing required for the press-forming is a line contact pressing on the designed radius of curvature 10.

[0015]

According to the present invention, there is provided an apparatus for simply manufacturing a helical laminated material of any shape as designed. For example, in the case of manufacturing a wooden spiral slide, the bottom plate portion requires a wide spiral spiral laminated material having many members to be laminated. In a wide spiral shape, the helical inclination angle changes with a change in the radius, but the complete plane portion is only on the radiation passing through the center of the design radius of curvature on the line connecting the inner and outer peripheral portions of the bottom plate. In the present invention, since vertical pressing is performed on the radiation, a spiral laminated material with high accuracy can be manufactured even when the lamination width is wide.

When the side beam of the spiral staircase is made of a helical laminated material, the radius and the helical inclination angle vary between the inner and outer beam beams. In the present invention, the horizontal pressing device is moved horizontally on the ruler board. It is possible to easily manufacture a side girder using a predetermined helical laminated material alone.
