Description

{APPARATUS FOR FORMING MATERIAL}

The present invention relates to a material forming apparatus, and more particularly, to a material forming apparatus for forming a material.

In recent years, carbon fiber composite materials such as carbon fiber reinforced plastics (CFRP) have been applied not only to metal plates or non-ferrous metal plates as body materials, but also to high strength and light weight of automobiles.

Since the carbon fiber composite material is excellent in strength, elastic modulus, light weight and stability, it is widely regarded as one of the main materials in the aviation and automobile fields requiring high performance. When the economic condition is solved, Is expected to increase dramatically.

In particular, carbon fiber composite materials in the automotive industry tend to use carbon fiber mainly as a core of resin such as epoxy or plastic. That is, the carbon fiber composite material is a high-tech composite material which is made of carbon fiber in the form of a winding or a fabric, and then cured by impregnating the resin in a resin stream, which is a high-strength composite material.

In such a carbon fiber composite material, the resin has an excellent hardness, while the tensile strength is weak so that it is easily broken. The carbon fiber has a high tensile strength, but has no bending repulsion.

Further, the carbon fiber can be lightened by a weight of 1/4 of that of the steel of the same volume, and the tensile strength is ten times stronger, which is advantageous in securing rigidity, and is also advantageous in moldability.

However, in order to apply the carbon fiber composite material as described above to a vehicle body, it is used by being bonded to a metal material such as a steel plate or an aluminum plate material which is difficult to replace.

In detail, although not shown in the drawing, a strip-shaped metal material is first cut into a metal sheet having an area of a predetermined size, and a strip-shaped carbon fiber composite material is cut in an area similar to the metal sheet And cut into a carbon fiber composite sheet.

1, the worker W places the metal sheet 1 on the support plate 4, applies the adhesive 7 to the upper surface of the metal sheet 1, 2 are laminated on the upper surface of the metal sheet 1 and bonded to each other to form a bonding sheet 3. [

Thereafter, the bonding sheet 3 is placed in the heating device 8 and heated to a predetermined temperature. Then, the bonding sheet 3 is taken out of the heating device 8 and put in a press forming device 9 for press forming.

Such a material forming process is a process in which a metal material 11 and a carbon fiber composite material 12 are formed into a sheet metal sheet 1 and a carbon fiber composite sheet, batch process and manual process, it is time consuming and product quality is not excellent.

[

The variable roll forming unit 200 is disposed at the rear end of the continuous joining unit 100 and is joined to the joining material 100 having the metal material 11 and the carbon fiber composite material 12 joined thereto 13).

Here, the variable roll forming unit 200 may include a forming member 210 and a heating member 220.

The formed member 210 is formed into a desired shape of the continuous joint material 13, and thus can produce automobile parts and the like having various sectional shapes.

The heating member 220 heats the variable shaping roll 211 so that the variable shaping roll 211 warms the joining material 13. Since the carbon fiber composite material 12 is well formed through the warm forming process, the metal roll 11 can be easily formed on the surface of the variable shaping roll 211, So that the bonding material 13 can be warm-formed.

Specifically, the heating member 220 may include a first bearing 221, a second bearing 222, and an electric line 223.

The first bearing 221 is coupled to one rotation shaft 211a of the variable forming roll 211.

On the other hand, Electricity may be supplied from the second bearing 223 to the second bearing 222, the variable shaping roll 211 and the first bearing 221 to finally exit through the first bearing 221 side electric line 223 .

At this time, the variable shaping roll 211 is heated by the resistance heating method while the electricity flowing in this way passes through the variable shaping roll 211.

Further, due to the inner ring and the rotary wheel configuration which are independently rotatable, which are the bearing structural characteristics of the first bearing 221 and the second bearing 222, the electric line 223 can be rotated even during the rotation of the variable- The variable shaping roll 211 can be heated while electricity supplied from the first bearing 221, the variable shaping roll 211, and the second bearing 222 passes through the first bearing 221,

As described above, the first bearing 221 and the second bearing 222 serve as an electric transfer medium in the rotary configuration, which allows the variable shaping roll 211 to supply electricity even while it is rotating.

In addition, each of the first bearing 221 and the second bearing 222 may be supported by a supporting bracket 224 made of a heat insulating material and an insulating material. That is, the support bracket 224 has a structure that supports the first bearing 221 and the second bearing 222 while supporting the first bearing 221 and the first bearing 221, And the second bearing 222 prevent the external structure and the operator from being damaged by heat and electricity.

The electric line 229 is connected to the cover coil 228 and supplies electric power to the cover coil 228 to heat the cover coil 228 so as to be adjacent to the inside of the cover coil 228 So that radiant heat can be sent to the arranged variable shaping rolls 211.

The variable roll forming unit 200 may include a non-contact type temperature sensor 230 and a controller C as shown in FIGS.

Here, the non-contact type temperature sensor 230 is disposed on one side of the variable-form roll 211 so as to measure the temperature of the variable-form roll 211 in a non-contact manner. The noncontact temperature sensor 230 may be an infrared temperature sensor, for example, and is not limited to the present invention, and any conventional noncontact temperature sensor may be used.
