ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a cutting apparatus, more particularly to an apparatus for cutting a scrap tire.
2. Description of the Related Art
It is known that scrap tires are bulky and hard to handle. Therefore, a relatively large space is required to store the scrap tires.
SUMMARY OF THE INVENTION
The object of the present invention is to provide an apparatus for cutting scrap tires in order to reduce greatly the space for storing the scrap tires.
According to the present invention, an apparatus for cutting a scrap tire comprises a base with a top face, a vertical shaft mounted on the base, a tire support mounted rotatably on the vertical shaft, and first and second cutting units. The first cutting unit is mounted on the base and is adapted to cut the scrap tire along a first plane that is parallel to the top face of the base. The first cutting unit includes a first movable seat that is slidable on the top face of the base, a first stationary seat which is fixed on the top face of the base and which is spaced apart radially from the vertical shaft, a first hydraulic cylinder mounted on the top face of the base and connected to the first movable seat in order to move the first movable seat toward the first stationary seat so as to be adapted to clamp the scrap tire against the first stationary seat, a first cutter mounted on the first movable seat and adapted to cut the scrap tire when the scrap tire is clamped between the first movable and stationary seats, and a driving mechanism mounted on the base for actuating the first cutter to cut the scrap tire when the scrap tire is clamped between the first movable and stationary seats. The second cutting unit is mounted on the base and is adapted to cut the scrap tire along a second plane that is perpendicular to the top face of the base. The second cutting unit includes a second movable seat that is slidable on the top face of the base, a second stationary seat which is fixed on the top face of the base and which is spaced apart radially from the vertical shaft and angularly from the first stationary seat, a second hydraulic cylinder mounted on the top face of the base and connected to the second movable seat in order to move the second movable seat toward and away from the second stationary seat, a second cutter mounted on the second movable seat, and a third cutter mounted on the second stationary seat. The second movable seat and the second stationary seat clamp the scrap tire therebetween when the second hydraulic cylinder moves the second movable seat toward the second stationary seat in order to enable the second and third cutters to shear cooperatively the scrap tire.
