Description

Cutting machine for composite laminates

The present invention relates to a cutting machine dedicated to a composite laminate, and more particularly, a fixing means for fixing the composite laminate is transferred to a set position in consideration of the thickness and number of layers of the composite laminate, and then cutting is performed. It relates to a cutting machine dedicated to composite laminates that reduces the delamination phenomenon that occurs, prevents defects in which the rear surface of the cut surface becomes very rough, and enables cutting of highly ductile materials such as natural fiber materials.

In general, a composite laminate material formed of a resin and reinforcing fibers has properties such as high strength, specific strength, and impact resistance, and has required physical properties such as strength required by appropriately adjusting the type of resin and reinforcing material, the number of layers, and fiber orientation. It has the characteristic of being able to properly reinforce The frequency is continuously increasing.

As described above, since composite laminates, which are highly usable in various fields, are generally made of expensive materials, it is natural that a defect in the product will result in significant economic loss. In particular, as the processing of the composite laminate is performed after the molding process for the manufacture of the composite laminate is completed, when a defect occurs due to processing, the economic loss is greater.

In addition, the composite laminate is manufactured by laminating several layers and then molding under high temperature and high pressure, and thus has properties and properties significantly different from those of conventional materials. In particular, the physical properties in the lamination direction are relatively weak compared to the physical properties in the lamination surface, and delamination, which does not occur in general isotropic materials, may occur. When such delamination occurs in the composite laminate, the function of the material is clearly lost.

Nevertheless, since the cutting processing of the composite laminate is to be performed inevitably, it must be done carefully so that delamination does not occur in performing the cutting processing of the composite laminate.

On the other hand, the cutter is configured to include a cutting blade to cut an unspecified material, and the material is cut by moving the cutting blade from the upper side to the lower side while the material is fixed, or the material is cut while the cutting blade is fixed. It is configured to cut the material by moving to the side.

However, the cutter according to the prior art as described above is for cutting an unspecified material, and was not suitable for cutting a specific material exclusively.

Accordingly, a garlic root cutting device for cutting the root of stem garlic has been developed and disclosed.

In this regard, in Korean Patent No. 10-0458004, a cutting blade for cutting garlic, a supply stand for supplying garlic, and a protrusion chain for transferring the stem and whole garlic at a constant speed when garlic is supplied, etc. It is intended to efficiently cut garlic by providing a.

However, the garlic root cutting device according to the prior art has a problem in that it is suitable for cutting garlic roots, but is not suitable for cutting a composite laminate.

That is, in other cutting devices such as the garlic root cutting device, there was a problem in that damage caused by delamination caused by cutting the composite laminate was not taken into account.
