本発明は板材を重合圧接してなる複合材の製造
方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for manufacturing a composite material formed by polymerizing and press-bonding plate materials.
異種金属からなる複数枚の板材を重合圧接して

BACKGROUND ART Composite materials made by polymerizing and press-welding a plurality of plates made of different metals have a predetermined function by combining the properties of each metal, and are widely used in various fields. For example, a bimetal is a typical composite material made by polymerizing multiple plates made of metals with different coefficients of thermal expansion, and a plate made of a metal with spring properties and a plate made of a conductive metal. The combined composite material is used in electrical contact springs, etc.
一般に、これら複合材を製造する場合には、帯
状をなす複数枚の板材を重合する冷間圧接法、ま
たはビレツト形状をなす複数枚の板材を重合し、
爆発圧接、摩擦圧接、溶接等を経て熱間圧接する
熱間圧接法がある。 Generally, when manufacturing these composite materials, a cold pressure welding method is used to polymerize a plurality of strip-shaped plates, or a plurality of billet-shaped plates are polymerized.
There is a hot welding method that involves hot welding through explosion welding, friction welding, welding, etc.
しかして、冷間圧接加工は、板材を圧接するた

このことから１台の熱間圧延機で小さな加工率の
加工を繰返して行なえる。また、通常の単一材の
圧延が使用できる等の汎用性があるので、設備面
で大変経済的であるという利点がある。 However, in cold pressure welding, processing must be performed at a large processing rate of 40 to 70% in order to pressure-weld the plates, so heavy processing is required in proportion to the finished plate thickness and width, requiring large-scale processing. Requires equipment.
Also, because of this, the processing equipment has a special structure and is not versatile, as it cannot perform normal reverse rolling.
The drawback is that it is very uneconomical in terms of equipment. On the other hand, in hot pressure welding, the plates are heated and softened, so it is relatively easy to press the plates together, and it is possible to repeat the process at a small processing rate, so the processing equipment can be used as usual regardless of the finished plate thickness. Good for rolling mill scale. Also,
For this reason, processing at a small processing rate can be performed repeatedly with one hot rolling mill. In addition, it has the advantage of being very economical in terms of equipment because it has versatility, such as being able to use normal rolling of a single material.

組み合せのもの及び被加工材が大型化する程著し
い。 However, in composite materials, there may be large differences in deformation resistance among the metals forming each plate material. In this case, if a plate made of a metal with low deformation resistance and a plate made of a metal with high deformation resistance are stacked and rolled, the elongation of the former plate in the longitudinal and width directions will change depending on the difference in deformation resistance. It is larger than the latter plate material. However, in the case of cold welding, there is no problem because the difference in elongation between the plates can be adjusted by tension, but in the case of hot welding, the elongation of metal plates with low deformation resistance increases. A large shearing force acts on the joint surface. For this reason,
If the weld is damaged due to this shearing force, the plate material will peel off. If the welding is strong, the metal plate with low deformation resistance will warp in the rolling direction, making it difficult to pass the plate through the pressure roll, reducing work efficiency, and causing each plate to deteriorate due to temperature drop, etc. Pressure welding becomes difficult, and the yield of pressure welding processing decreases. In particular, this tendency becomes more pronounced as the combinations have a larger difference in deformation resistance and as the workpiece becomes larger.
従つて、変形抵抗の差が大なる板材を組合せた
複合材を製造する場合に、熱間圧接加工は前記の
ように加工が困難であるので、やむ得ずに設備面
で不利な冷間圧接加工を行なつている。 Therefore, when manufacturing a composite material that combines plates with large differences in deformation resistance, hot welding is difficult as described above, so cold welding, which is disadvantageous in terms of equipment, is unavoidable. Processing is in progress.

The method for manufacturing a composite material of the present invention includes polymerizing outer materials on both upper and lower surfaces of an intermediate material, and fixing the entire peripheral edge of the intermediate material to the outer material during hot welding. The present invention is characterized in that a workpiece is formed by arranging a frame member that stretches in a stretched state, the workpiece is subjected to hot pressure welding, and then the frame member is removed.

つた複合材を、熱間圧接加工により製造する。 The method for producing a composite material of the present invention involves forming a composite material product by using an intermediate plate made of a metal with relatively low deformation resistance and a pair of metal plates made of a metal with relatively high deformation resistance. The outer plates are combined and hot rolled. The frame members made of metal are fixed to both outer side plates and arranged on both side edges and both end edges of the intermediate plate. The workpiece thus formed is passed through a pressure roll while being heated to press the intermediate plate material and both outer side plate materials. In this case, the frame material presses the peripheral edge of the intermediate plate material, suppressing the elongation of the intermediate plate material in the longitudinal direction and the width direction within the range of elongation of the outer plate material. For this reason, the intermediate plate does not stretch more than necessary and is securely pressed against the outer plate. Therefore, the intermediate plate material and both outer side plate materials can be easily and reliably pressed together, and the workpiece can be smoothly passed through the pressure rolls to perform the pressure welding process. After hot welding, the frame material is cut out from the workpiece. In this way, a composite material in which plate materials having a large difference in deformation resistance are assembled is manufactured by hot welding.

なお、中間の板材となる部分には、変形抵抗の小
さいものを位置させる。 In the manufacturing method of the present invention, the plate material of the intermediate layer is a single layer or multiple layers. That is, when the intermediate plate material is a single layer, a three-layer composite material consisting of the intermediate material and both outer plate materials is manufactured singly. When the intermediate plate material has multiple layers, it is manufactured by manufacturing a single composite material having four or more layers, or by polymerizing multiple sets of composite materials having two or more layers.
Note that a material with low deformation resistance is placed in the portion that will become the intermediate plate material.

の板材とともに中間の板材を包囲する。 One form of the frame material is to form the frame material separately from the outer plate material, arrange it around the entire periphery of the intermediate plate material, and weld the frame material to both outer plate materials. . Another embodiment of the frame is to form the frame integrally with one or both of the outer plates and to surround the intermediate plate with the outer plates.

の熱間加工性が良い金属を用いる。 It should be noted that the frame material expands while being firmly fixed to the outer plate material during the hot-pressure welding process, and can suppress the elongation by pressing the intermediate layer plate material. The frame material used has a high or low deformation resistance depending on the metal of the intermediate and outer plate materials. In addition, when welding the frame material to the outer plate material, the frame material has good weldability with the outer plate material, and the formed bead (alloy)
Use a metal with good hot workability.

When manufacturing this bimetal, plate materials 1 to 3 are arranged as shown in FIG.

It has good weldability compared to other alloys, and has lower deformation resistance than these alloys. and,
Electron beam welding is performed in a vacuum between the joining edges of the plates 1 and 3 and the frame material 4 to form a welded portion 5, and the frame material 4 is fixed to the plates 1 and 3 at this welded portion 5. For this reason, the intermediate plate material 2 is surrounded and held down by the frame material 4 on its entire peripheral edge. The thus constituted workpieces are passed through a pressure roll and subjected to hot pressure welding, thereby welding each of the plate materials 1 to 3 together. In this case, the elongation of the plate material 2 is suppressed by the frame material 4, and the plate material 2 is securely pressed against the plate materials 1 and 3. After pressure welding,
Each frame member 4 is separated from the entire peripheral edge of the plate members 1 to 3 by machining, resulting in the state shown in FIG. In this case, since the frame material 4 is placed in contact with the peripheral surfaces of the plate materials 1 to 3, by cutting the frame material 4 along the welded portion 5, it is possible to separate only the frame material 4. can. For this reason, when cutting the frame material 4, the plate materials 1 to 3
