Description

The present invention relates to a spinning processing device, a processing roller for spinning processing, a spinning processing method, and a method for manufacturing a plastically processed product of a thermoplastic resin composite material.

In recent years, resin materials have been utilized in various industrial fields. As such resin materials, in addition to those made of a single resin, resin composite materials such as reinforced plastics, which are made by combining resin with fibers to increase strength, are known. Moreover, there is an increasing demand for technology that can easily obtain processed products made of such resin materials at low cost.

Fiber-reinforced plastic, which is one type of reinforced plastic, is attracting attention as a lightweight material that can replace metal because of its light weight and strength. This fiber-reinforced plastic is commonly made using thermosetting resin, but thermosetting resin requires time to harden and has a long molding time, so it is not suitable for mass production of processed products. The problem is that it is not suitable.

Therefore, studies are being conducted on processing techniques for utilizing thermoplastic fiber-reinforced plastics using thermoplastic resins as resin materials.
For example, Patent Document 1 discloses a molding apparatus for molding a material to be molded containing a thermoplastic resin and reinforcing fibers, which defines first and second molds and the relative positional relationship between the two molds. A press device is described which includes a ram that does this.

[First embodiment]
(Spinning processing equipment)
FIG. 1 is a schematic explanatory diagram showing the structure of a spinning processing apparatus 1A according to a first embodiment of the present invention. A spinning processing apparatus 1A according to a first embodiment of the present invention includes a processing roller 2 and a heating section 3, as shown in FIG. Furthermore, the spinning processing apparatus 1A includes a fixing means 4 for fixing the thermoplastic resin composite material T1 to be processed. In this embodiment, as shown in FIG. 1, the cylindrical thermoplastic resin composite material T1 is subjected to plastic processing, but the shape of the thermoplastic resin composite material T1 is as follows. It is not limited to.

The spinning processing device 1A includes a rotation mechanism (not shown) that rotates around a rotation axis R1, a main shaft 5 connected to this rotation mechanism, and a fixing means for fixing the thermoplastic resin composite material T1 to the main shaft 5. It is equipped with 4. The thermoplastic resin composite material T1 is fixed to the main shaft 5 by the fixing means 4, and is attached so as to rotate around the rotation axis R1. Note that the main shaft 5 may have a movement axis in addition to the rotation axis R1. Accordingly, during plastic processing, the thermoplastic resin T1 composite material itself may be moved and processed.

Further, the spinning processing apparatus 1A includes a processing roller holder 6 for attaching the processing roller 2. The processing roller 2 is attached to the processing roller holder 6 and rotates about the rotation axis R2. In addition, in FIG. 1, the rotation axis R2 is arranged so as to be parallel to the rotation axis R1 of the main shaft 5, but the rotation axis R2 is not limited to this. The arrangement direction of the rotation axis R2 (the angle of the rotation axis R2) can be determined as appropriate depending on the shape of the processing roller 2 itself and the type of processing performed by the processing roller 2. Note that it is preferable that the processing roller holder 6 has a movement axis in addition to the rotation axis R2 and is movable. This makes it possible to place the processing roller 2 at the processing location P of the thermoplastic resin composite material T1 during plastic processing, and to perform plastic processing continuously by moving the processing roller 2. .

Each member will be explained in detail below.
<Fixing means>
The fixing means 4 is a means for fixing the thermoplastic resin composite material T1 to the main shaft 5 connected to the rotation mechanism. The fixing means 4 of this embodiment may be any means as long as it can fix the thermoplastic resin composite material T1 to the main shaft 5 without interfering with the drive range of the processing roller 2.
Examples of the fixing means 4 include those that act from the outer circumferential surface of the thermoplastic resin composite material T1 and those that act from the inner circumferential surface of the thermoplastic resin composite material T1. As such a fixing means 4, a fixing device called a jig or a chuck may be used.

As the fixing means 4, for example, as shown in FIG. 1, a fixing device (chuck) provided on the main shaft 5 and capable of clamping and fixing the outer peripheral surface of the thermoplastic resin composite material T1 can be used. . In addition, as another example of the fixing means 4, the fixing means 4 can be inserted into the inside of the thermoplastic resin composite material T1 and pressed toward the outer circumferential side of the thermoplastic resin composite material T1, thereby fixing the thermoplastic resin composite material T1 on the main shaft 5. Examples include using a core rod that can be fixed.

Although the thermoplastic resin composite material T1 shown in FIG. 1 has an open cylindrical shape, it may have a bottomed shape, for example. Moreover, the cylindrical shape of the thermoplastic resin composite material T1 is not particularly limited, and may be a cylindrical shape, an elliptical cylindrical shape, or a polygonal cylindrical shape. From the viewpoint of realizing stable rotation, a cylindrical shape is preferable.

<Processing roller>
The processing roller 2 is used for plastic processing of the thermoplastic resin composite material T1.
The processing roller 2 in this embodiment may be any roller that can perform plastic processing by contacting the thermoplastic resin composite material T1, and its specific structure is not particularly limited.
As a specific example of the processing roller 2 of this embodiment, for example, a processing roller used for spinning processing may be used. Spinning processing is one of the plastic working methods in which rollers or the like are brought into contact with a rotating workpiece to form the object.

The processing roller 2 is a structure that can rotate around a rotation axis R2. The shape of the processing roller 2 may be any shape, and in addition to the disk shape shown in FIG. 1, it may also be cylindrical, elliptical, polygonal, etc. From the viewpoint of stable rotation, it is preferable to have a cylindrical shape or a disk shape.

Furthermore, the shape of the processing roller 2 may be selected depending on the processing content, for example. For example, one with a diameter-reducing surface used for diameter-reducing treatment to reduce the diameter of the end of the workpiece, one with an end-pushing surface used in end-pressing treatment to press the end surface of the workpiece, Examples include those having a grooving surface used for grooving to form grooves on the inner or outer circumferential surface of an object.

Further, although FIG. 1 shows the processing roller 2 disposed on the outer peripheral surface side of the thermoplastic resin composite material T1, the present invention is not limited thereto. The arrangement of the processing roller 2 can be changed as appropriate depending on the plastic processing content of the thermoplastic resin composite material T1. For example, the processing roller 2 may be arranged on the inner peripheral surface side of the thermoplastic resin composite material T1, It is also possible to process the inner circumferential surface of the resin composite material T1.

<Heating part>
The heating section 3 is for heating the thermoplastic resin composite material T1.
The heating unit 3 of this embodiment may be any member as long as it can heat the thermoplastic resin composite T1 itself or the thermoplastic resin contained in the thermoplastic resin composite T1 to a temperature higher than the glass transition temperature or softening point. Not particularly limited. Note that it is known that the glass transition temperature or softening point of general thermoplastic resins is 300 degrees or less. For this reason, it is preferable to use a heating unit 3 that can raise the temperature up to 300 degrees, but the temperature increase range of the heating unit 3 is limited to the thermoplastic resin composite material T1 itself or the thermoplastic resin composite material to be processed. It can be appropriately set depending on the glass transition temperature or softening point of the thermoplastic resin contained in T1. Therefore, the upper limit of the temperature increase range of the heating section 3 may be set to 300 degrees or less.

The heating section 3 is preferably one that heats only the portion of the thermoplastic resin composite T1 where plastic working is to be performed. This makes it easy to control the temperature of the thermoplastic resin composite material T1, and it becomes possible to obtain a plastic processed product with stable quality.

As an example of the heating section 3 that heats only the portion of the thermoplastic resin composite material T1 to be subjected to plastic working, as shown in FIG. 1, the processing roller 2 and the heating section 3 may be integrated. Note that the integration of the processing roller 2 and the heating section 3 does not only mean that the processing roller 2 and the heating section 3 are structurally integrated, but also that the processing roller 2 itself is heated at a temperature necessary for plastic processing of the thermoplastic resin composite material T1. This includes a mechanism that is equipped with a heating section 3 as a mechanism that directly or indirectly applies heat to the processing roller 2. As a result, the thermoplastic resin composite material T1 is heated only at the location where the processing roller 2 contacts (processing location P), and plastic processing is performed. At this time, the thermoplastic resin composite material T1 other than the processing location P can be plastically processed without applying extra heat or pressure, making it easier to control the temperature of the thermoplastic resin composite material T1, resulting in a plastically processed product. It becomes easy to maintain uniform quality.

As an example of integrating the processing roller 2 and the heating section 3, as shown in FIG. These include, but are not limited to.
2 and 3 are schematic explanatory diagrams showing another aspect of the heating section 3 in this embodiment.
As an example of the heating section 3, as shown in FIG. 2, a heating device 31 such as a burner or a heater is provided as the heating section 3, and the processing roller 2 is heated in advance by the heating device 31. Further, as another example of the heating unit 3, as shown in FIG. The processing roller 2 may be heated by supplying energy from the energy supply source 33. Note that an example of the surface treatment means 32 includes applying an agent that absorbs electromagnetic waves (microwaves) and increases the temperature. Further, an example of the energy supply source 33 at this time is an electromagnetic wave generator or the like. As a result, the processing roller 2, whose temperature can be raised by electromagnetic waves by the surface treatment means 32, can be heated by irradiating electromagnetic waves from the energy supply source 33 (electromagnetic wave generator). becomes.

Note that the structure related to the processing roller 2 integrated with the heating section 3 can be made independent as a processing roller for spinning processing in the present invention. This processing roller for spinning processing can perform plastic processing of a thermoplastic resin composite material without press molding using a mold. Further, by applying the processing roller for spinning processing of the present invention to an existing spinning processing device, it becomes possible to easily upgrade the spinning processing device to a spinning processing device capable of plastic processing of thermoplastic resin composite materials.

(Spinning processing method (method for manufacturing plastic processed products of thermoplastic resin composite materials))
The spinning processing method of this embodiment includes a step of heating the thermoplastic resin composite material T1 as plastic processing of the thermoplastic resin composite material T1, and a step of plastic processing the heated thermoplastic resin composite material T1 with a processing roller 2. It is equipped with

As for the order of each processing step, first the step of heating the thermoplastic resin composite material T1 is performed, and then the step of plastically working the thermoplastic resin composite material T1 with the processing roller 2. Further, as described above, when the processing roller 2 and the heating section 3 are integrated, both steps can be performed at the same time.

The step of heating the thermoplastic resin composite material T1 is performed using the heating section 3 described above.
Further, the step of plastically working the thermoplastic resin composite material T1 with the processing roller 2 involves rotating the thermoplastic resin composite material T1 fixed to the main shaft 5 around the rotation axis R1 and around the rotation axis R2. By pressing the processing roller 2 against the processing location P of the thermoplastic resin composite material T1, the thermoplastic resin composite material T1 is plastically deformed. In addition, in FIG. 1, as an example of plastic deformation, by moving the processing roller holder 6 along the rotation axis R2, the processing roller 2 rotating about the rotation axis R2 is moved along the axial direction of the rotation axis R1. Although shown is a device that is driven to groove the cylindrical thermoplastic resin composite material T1, the present invention is not limited to this, and in addition to the shape of the processing roller 2, the angle of the rotation axis R2 and the processing roller By appropriately selecting the moving direction of the holder 6, various other types of plastic working may be performed.
By performing the above steps, it becomes possible to perform plastic working of the thermoplastic resin composite material T1 without using press working.

In particular, when using a thermoplastic resin composite material T1 that is a composite of thermoplastic resin and fibers, such as CFRTP, as a processing object, a process that heats the entire thermoplastic resin composite material T1 that is the processing object, such as press processing. It is known that when this is done, the resin impregnation rate between the fibers decreases, causing the fibers to fall apart, which tends to cause a decrease in the strength of the resin material, resulting in variations in the quality of plastic processed products.
On the other hand, the spinning method in this embodiment includes a step of integrating the processing roller 2 and the heating section 3 to heat the thermoplastic resin composite material T1, and a step of plastically processing the thermoplastic resin composite material T1 using the processing roller 2. They can also be done at the same time. As a result, heat treatment and pressure treatment are performed only on the processing point P where plastic processing is performed in the thermoplastic resin composite material T1, so the strength of the thermoplastic resin composite material T1 is less likely to decrease, and the plastic processed product has stable quality. It becomes possible to manufacture Therefore, the spinning method of this embodiment is also utilized as a method for manufacturing plastically processed products of thermoplastic resin composite materials.

[Second embodiment]
FIG. 4 is a schematic explanatory diagram showing the structure of a spinning processing apparatus 1B according to the second embodiment of the present invention. As shown in FIG. 4, the spinning processing apparatus 1B in the second embodiment of the present invention uses a flat thermoplastic resin composite material T2. Furthermore, the fixing means 40 for fixing the thermoplastic resin composite material T2 to the main shaft 5 is provided with a first member 40a and a second member 40b that sandwich the thermoplastic resin composite material T2. Note that description of the same components as in the first embodiment will be omitted.

The fixing means 40 in this embodiment fixes the thermoplastic resin composite material T2 to the main shaft 5, and may also function as a mold when plastically working the thermoplastic resin composite material T2. For example, as shown in FIG. 4, when the processing roller 2 presses the thermoplastic resin composite material T2, the thermoplastic resin composite material T2 is plastically processed along the side surface of the first member 40a. Thereby, it becomes easy to perform stable plastic working on the flat thermoplastic resin composite material T2 without using press working. Further, by appropriately designing the side shape of the first member 40a or the second member 40b of the fixing means 40, it becomes possible to perform local processing of the thermoplastic resin composite material T2 with high precision.
Note that the fixing means 4 in the first embodiment may also be provided with one that functions as a mold for plastically working the cylindrical thermoplastic resin composite material T1. This makes it possible to improve the accuracy of local processing also in plastic processing of the thermoplastic resin composite material T1.

[Third embodiment]
FIG. 5 is a schematic explanatory diagram showing the structure of a spinning processing apparatus 1C according to the third embodiment of the present invention. As shown in FIG. 5, a spinning processing apparatus 1C according to the third embodiment of the present invention uses a plurality of processing rollers 2A and 2B as the processing roller 2 of the spinning processing apparatus 1A according to the first embodiment. It is. Further, the processing rollers 2A and 2B are driven in conjunction with each other. Note that description of the same components as in the first embodiment will be omitted.

The spinning processing apparatus 1C of this embodiment may be any device as long as it includes two or more processing rollers, and is not limited to providing only two processing rollers 2A and 2B as shown in FIG.
As shown in FIG. 5, the processing rollers 2A and 2B are preferably arranged so as to sandwich the thermoplastic resin composite material T1 on the same plane. As a result, since the pressing process is performed while the thermoplastic resin composite material T1 is held between the processing rollers 2A and 2B, stable plastic processing is possible. In addition, although the processing rollers 2A and 2B have the same shape in FIG. 5, they are not limited to this. The working rollers 2A and 2B may have different shapes so that a plurality of types of plastic working can be performed at once.

In addition, in the spinning processing apparatus 1C of this embodiment, as the heating section 3, a structure similar to that of the spinning processing apparatus 1A of the first embodiment described above can be used. For example, at least one of the processing rollers 2A and 2B may be integrated with the heating section 3. In particular, as shown in FIG. 5, by providing a plurality of processing rollers 2A, 2B integrated with the heating section 3, such as providing a heating circuit 30 for all of the plurality of processing rollers 2A, 2B, thermoplastic resin composite material The heating efficiency with respect to T1 is improved, the molding time for plastic working can be shortened, and the precision of plastic working can be increased.

The spinning processing apparatus 1C of the present embodiment performs the plastic processing by driving a plurality of processing rollers (processing rollers 2A, 2B) in an interlocked manner, thereby performing pressure treatment and heat treatment on the plastic processing portion of the thermoplastic resin composite material T1. The efficiency of plastic working can be increased and the forming time of plastic working can be shortened. Furthermore, by shortening the molding time of plastic working, it is also possible to suppress a decrease in temperature of the thermoplastic resin composite material T1 during plastic working. This makes it easier to improve the precision of plastic working and to produce plastic processed products of stable quality. It also becomes possible to mass produce plastically processed products.

The spinning processing apparatus and the spinning processing method of the present invention can be used for plastic processing of a thermoplastic resin composite material in which fibers and a thermoplastic resin are combined. More specifically, it can be used for plastic processing of thermoplastic resin composite materials that require local processing.

Further, the processing roller for spinning processing of the present invention can be applied to a spinning processing device and used for plastic processing of thermoplastic resin composite materials. Furthermore, by applying the processing roller for spinning processing of the present invention to an existing spinning processing device, it is possible to easily upgrade the processing roller to a spinning processing device that can perform plastic processing of thermoplastic resin composite materials. .
