く貢献するという効果を奏するものである．[Detailed Description of the Invention] (Industrial Application Field) The present invention... A cylindrical body made of resin. [Prior art] Conventional method for manufacturing a composite cylindrical body having a structure fitted to a cylindrical or rod-shaped base material. A composite cylindrical body is made by providing a resin layer on the outer or inner circumferential surface of a cylindrical or rod-shaped base material, such as a resin roll made by providing a resin layer on the outer circumferential surface of a metallic base material that is a core material. Abrasion resistance of resin. chemical resistance. It is used in a wide range of areas due to its frictional properties and other properties. Manufacturing methods for such resin rolls include the casting method, in which the base material is set in a mold and liquid resin is injected, and the lining method, in which a resin sheet is attached to the base material. There are fitting methods such as fitting a resin cylindrical body such as a resin pipe into a base material, and an appropriate method is adopted depending on the characteristics and properties of the resin. The present invention is. Of these. This paper relates to a method for manufacturing composite cylinders using a fitting method. for example. Ultra-high molecular weight polyethylene. Casting methods cannot be used when manufacturing resin rolls using materials with poor melt fluidity, such as fluorine resins. First, resin pipes are manufactured using special methods such as ram extrusion molding and press molding. The resin pipe is fitted into a base material as a cylindrical body, and then the surface is processed. It is a roll product. How to fit the resin pipe into the base material.
#A Shrink fitting method in which the fat pipe is heated and expanded in advance and fitted into the Go material. A press-fitting method in which a pipe with an inner diameter slightly smaller than the outer diameter of the base material is forcibly fitted. Other methods such as using a collection tube are also in use. [Problem to be solved by the invention] However. In either case, it is not only difficult to attach the pieces using adhesive; Poor adhesion tends to occur due to residual adhesive solvent or uneven adhesive thickness, and perfect adhesion cannot be achieved. Also. It is not possible to secure strong adhesion with room temperature adhesion. In the case of ultra-high molecular weight polyethylene and fluororesin. There is no suitable adhesive. In case of poor adhesion or insufficient adhesion strength. The quality of the resin roll will deteriorate significantly. Rolls that are subject to particularly large loads, rapid repeated forward and reverse rotations, or sudden starts. Due to sudden stop. In applications where large shear forces are applied to the joint surfaces, the resin may become misaligned or deformed. Sometimes destruction occurs. To prevent this, countermeasures are taken, such as attaching flanges to both ends of the roll to mechanically fix it, or attaching a key to the base material to prevent it from slipping. It cannot be prevented sufficiently. Deformation and misalignment still occur. It also has poor durability and high cost. The present invention is. This was developed based on the problems of the prior art, and it is a resin cylindrical body that fits into a cylindrical or rod-shaped base material. The purpose of this study is to provide a method for manufacturing composite cylinders that adhere firmly and uniformly to a base material. [Means for Solving the Problems] The present invention. A cylindrical body made of resin. In a method for manufacturing a composite cylindrical body having a structure fitted to a cylindrical or rod-shaped base material. between the base material and the cylindrical body. An adhesive that develops adhesive properties when heated is interposed, and then ``. The surface layer of the base material in contact with the adhesive generates heat. The gist of this invention is a method for manufacturing a composite cylinder, which is characterized in that the adhesive properties of the adhesive are developed to adhesively bond the base material and the material to each other. In the present invention. The cylindrical body is made of resin. It is shaped separately from the base material to which it is fitted, and is usually extruded. Injection form. It is made by pressing etc. The resin material that makes up the cylindrical body includes: Almost all organic materials can be applied. This is advantageous for materials that are difficult to shape, such as ultra-high molecular weight polyethylene, fluororesin, and various rubber materials. Especially in the case of thermoplastic resins. When the adhesive is heated, the resin interface melts. Because they fuse together, the adhesive strength is strong and effective. The surface of the cylindrical body to be joined to the base material may be subjected to surface treatment, pretreatment, etc. to improve adhesion to adhesives, if necessary. The base material is. Mainly steel. Al ξ
It is made from metals such as aluminum. Also on the joint surface of this base material to the cylindrical body. If necessary, surface treatment and pretreatment can be applied to improve adhesion to adhesives. The adhesive used in the present invention has the property of developing adhesive properties when heated, and is easy to handle at room temperature. It must also be able to provide strong adhesion between the cylindrical body and the base material. The process of interposing this adhesive between the base material and the cylindrical body will be described later. Prior to fitting the base material and the cylindrical body, it is preferable to apply the adhesive to at least one of the base material or the cylindrical body. Therefore, an adhesive suitable for the lining material is selected as the adhesive. That is preferable. As a representative example. Thermosetting epoxy adhesive. Thermosetting polyester adhesive, thermosetting acrylic adhesive,
Adhesive polyolefins, thermoplastic elastomers, uncrosslinked rubber materials, and hoftmelt adhesives. Examples include modified fluororesins. When constructing the cylindrical body from ultra-high molecular weight polyethylene, consider workability and adhesive strength. Adhesive polyolefins are optimal. The adhesive is in sheet form. Liquid. It can be applied in various forms such as powder form. In either case. Apply the adhesive before fitting the base material and the cylindrical body. It is attached to the joint surface of the base material to the cylindrical body (hereinafter referred to as the "base material surface").
Fit the cylindrical bodies when the adhesive properties of the adhesive surface have decreased or disappeared. for example. If the adhesive is in powder form. The material is melted by heat on the base material surface and allowed to cool and solidify. In case of sheet form. Wrap and adhere to the base material surface. Furthermore, if it is liquid. Apply and let dry. in this way. The adhesive is attached to the base material surface. The operation is easy and the adhesion depth can be made uniform. Also. The fit between the base material and the cylindrical body. This is done when the adhesive properties of the adhesive surface have decreased or disappeared. Easy to handle. Moreover, there is almost no peeling of the adhesive. For this reason. Easy to fit between the base material and the cylindrical body. Moreover, the adhesive can be applied uniformly. In addition. Adhesives are not limited to being attached to the base material surface. It may be attached to the surface of the cylindrical body that is to be bonded to the base material. Also. It may be attached to both the base material and the cylindrical body. Furthermore. Adhesive may be supplied between the cylindrical body and the base material at the same time as the fitting. How to fit the base material and the cylindrical body. It is not particularly limited.
Any method, e.g. There is a shrink-fitting method in which a resin cylindrical body is heated and expanded in advance and then fitted into the base material, a press-fitting method in which a cylindrical body with an inner diameter slightly smaller than the outer diameter of the base material is forcibly fitted, and other cylindrical bodies. You can use a method such as using a shrink tube. The material may be selected appropriately depending on the characteristics of the materials constituting the cylindrical body and the base material. After interposing the adhesive between the base material and the cylindrical body. The adhesive is heated to develop adhesive properties. For this heating, for example, the entire body is heated in an electric furnace. Although it is possible to bond the mating cylinder, it will deteriorate if the entire mating cylinder is heated for a long period of time. Occurrence of strain and deformation due to residual stress, occurrence of peeling due to differential thermal expansion, etc. This is because there are many problems. It is best to perform bonding work in a short period of time and heat only the necessary adhesive areas. From this point of view, in the present invention. The surface layer of the base material in contact with the adhesive generates heat, which heats the adhesive. Note that in the present invention, the portion of the base material that generates heat is not necessarily limited to the surface layer. It may also contain other parts, e.g. If the base material is a thin cylinder, the entire wall of the cylinder may generate heat. however. If you take care to heat only the surface layer. This is preferable because the adhesive can be heated in a shorter time. This is a method for generating heat in the surface layer of the base material.
The induction heating method can generate heat only in the surface layer of the base material in a short time. It is most suitable due to its accuracy and uniformity of temperature control, simplicity of equipment and construction, etc. The present invention is not limited to this. Other methods such as resistance heating may also be used. The induction heating method.
For this reason, local heating can be easily performed. for example.
The temperature required for bonding. Even when the temperature is higher than the heat resistance temperature or melting point of the resin of the fitted cylindrical body. Because heating only the adhesive layer can be done in a short time, it is possible to perform bonding processes that would not be possible with heating the entire adhesive layer. Also, the results. There is almost no deformation or deterioration of the base material or cylindrical body, and dimensional accuracy is good. Also. Can also handle thick resin items and irregularly shaped thick items. This is possible by adjusting the working conditions. The economy is also very good. A typical example of a composite cylindrical body produced by the method of the present invention is a resin roll. It is not limited to this. for example. Process the surface of the fitted cylindrical body. It may also be a gear or cam. In addition, external resin-lined pipes and internal resin-lined pipes can also be cited as examples of composite cylinders, and can be manufactured by the method of the present invention. [Function] As described above, in the present invention, when a resin cylindrical body is fitted to a cylindrical or rod-shaped base material, a cylindrical body is formed between the two. It contains an adhesive that becomes adhesive when heated. after that. By generating heat in the surface layer of the base material that is in contact with the adhesive, the adhesive properties of the adhesive are developed and the base material and the cylindrical body are bonded to each other. It is possible to strengthen the bond between the cylindrical body and the base material, and improve the durability of the resulting composite cylindrical body. here. Since the adhesive is heated by generating heat in the surface layer of the base material, it is faster than heating a resin cylindrical body from the outside and heating the adhesive through the cylindrical body.
Heating can be done in a short time, there is almost no deformation or deterioration of the base material or cylindrical body, and dimensional accuracy is good. Also. It is also possible to process items with thick resin or unusually thick walls by adjusting the working conditions. Furthermore. What is the adhesive used to join the base material and the cylindrical body? This adhesive is a type that develops adhesive properties when heated. It is possible to attach the material to the base material or the cylindrical body in advance, and to fit the base material and the cylindrical body with the surface adhesiveness reduced. This simplifies the process of interposing the adhesive between the base material and the cylindrical body, and allows uniform distribution of the adhesive. [Example] Example 1. In Figure 1.
