Description

Cutting apparatus of casting media {the cutting apparatus of left thing after casting}

The present invention is a device for processing the leftover material and defective castings after processing the casting product, to be crushed finely for recycling, more specifically, a fixed plate having a plurality of cutting blades facing each other facing each other The object to be crushed is inserted between the plate and the moving plate, and the object is crushed by the moving plate, and the rotating shaft of the moving plate can be moved left and right to adjust the accommodation space according to the size of the object. And it relates to a cutting device of the casting material to allow the inclination of the moving plate is properly adjusted to allow the pulverized product to be discharged smoothly.

In addition, the present invention has a circular cross-section to prevent abrasion of the cutting blade that is in direct contact with an object, and the cutting of the casting media to prevent direct wear of the cutting blade by forming a weld on the outer surface. Device.

Various apparatuses for crushing casting media or defective products have been devised. Hereinafter, a method and apparatus for crushing and cutting frozen, hot water and defective products for casting of Patent Registration No. 184318 will be described. 1 shows a perspective view thereof.

Grinding, cutting and cutting methods for frozen, hot water and defective products for casting according to the prior art are crushed, cut, broken down, and broken down for use as hydraulic and natural drops. Crushing and cutting method and apparatus for producing an optimal raw material for coarse raw material, the apparatus comprising a fixed tooth device having a plurality of mountain teeth and a swinging tooth device having a plurality of mountain teeth in engagement with the mountain teeth. It is characterized by having a v-shaped area composed of a long columnar object, having a band-shaped sawtooth for grinding the runner, the method is a step of injecting a defective product, etc. into the v-shaped area, and pulverized by the upward swing. Creates raw materials for casting that discharge only the unnecessarily processed products that are cut into small pieces by repeating the cutting, grinding and cutting processes. And it is composed of information.

The apparatus according to the prior art puts the article to be processed into a V-shaped space made by the fixed tooth device and the oscillating tooth device, and compresses and crushes the article to be processed so that the rotation shaft of the oscillating tooth device is fixed. There is a problem in that the size of the object can be increased and the swinging tooth device is rotated by a hydraulic mechanism, so that the object pops out in the form of a V-shape when contacted with the object, thereby increasing the risk of a safety accident.

Next, as another conventional technology, a sizing apparatus of a casting medium of Patent Registration No. 1993-0004471 will be described, and FIG. 2 shows a longitudinal front view of an embodiment thereof.

In the above-described prior art, the vertical direction of the box is the discharge and discharge direction of the filter medium, the upper opening of the box is used as the inlet 10, and the opening and closing bottom plate 12 disposed at the bottom is used as the outlet. The other die which fixes the plate type die which the horizontal direction was made into the press division direction of the media by a pair of die | dye, and formed the horizontal recessed recess part of the horizontal direction in the pressure opposing surface to the box body, and presses it by a hydraulic unit. Is a cross blade die comprising a horizontal blade having a V-shaped recess and a similar protrusion of a plate die, and a vertical blade orthogonal to the casting die.

The sizing device of the casting media of another prior art is composed of a horizontal blade and a vertical blade so that the casting medium is not crushed finely, and the horizontal blade and the vertical blade which are always vertically operated are exerted only in a certain direction. There is a problem that the grinding efficiency is low. That is, there is a problem that a larger force is required because the direction in which the force acts regardless of the object is constant.

Therefore, the present invention devised to solve the above problems can change the volume of the receiving space according to the size of the object to be injected, and also by changing the point of action of the force depending on the shape of the object casting material having a higher grinding efficiency An object of the present invention is to provide a cutting device.

Another object of the present invention is to provide a cutting device for casting media that can extend the life by preventing the cutting of the cutting blade to be in direct contact with the object to be crushed.

And the conveyor (60) for supplying the material and the vibration feeder (70) for moving the discharged pulverized material is a general known art bar will be omitted herein.

Next, with reference to the accompanying Figure 6 will be described the operation principle for the cutting device of the casting medium according to an embodiment of the present invention. 6 is a schematic view showing a positional relationship between the fixed plate and the moving plate.

First, the a (a) of FIG. 6 has a rotation shaft 34 of the movable plate 30 positioned at the leftmost side, and the movable plate 30 is accommodated in the receiving space part 50 about the rotation shaft 34. It shows the case of pressurizing the object put into it. In such a case, it is applied when the volume of the object to be added is large or large so that the volume of the accommodation space 50 needs to be increased. In the state of the a (a), since the pivot shaft 34 is located far from the fixed plate 20, the movable plate 30 is rotated about the pivot shaft 34 to pressurize an object and partially To shred. The partially crushed pulverized product is moved to the lower part, and in order to pulverize the pulverized product more finely, the rotating shaft 34 is advanced to close the distance to the fixed plate 20 and then the movable plate 30 is again. The powder can be pulverized into smaller particles by rotating it to pressurize the pulverized product once more.

Next, the b (b) of FIG. 6 is a view showing that the rotating shaft 34 is located at the rightmost side, and the moving plate 30 is rotated about the rotating shaft 34 to crush the injected casting media. . In the state of the b (b), the volume of the receiving space 50 is a minimum state, so the volume of the insertable object is limited, and when the first object is inserted, the upper end of the movable plate 30 is rotated to the right. The fixing plate 20 is formed in a valley shape in a state. When the object to be crushed in the above state is put into the crushing occurs from the top and the crushed is to be crushed smaller by rotating the moving plate 30 fall to the bottom.

In addition, when the injected casting media is not crushed at once, the vulnerable portion of the casting media is changed by changing the working point formed on the casting media by pressing the casting media while adjusting the position of the pivot shaft 34 of the moving plate. To form the starting point of destruction.

In addition, as the angle of the fixing plate 20 is also adjustable, it is possible to perform the shredding operation under the optimum conditions by adjusting the inclination by the type of the object to be introduced.

The present invention by the configuration as described above has the effect of improving the workability by appropriately adjusting the receiving space according to the size or capacity of the object to be put in the crushing the casting medium or defective products.

In the case of the casting media or the like that is not crushed at once, the rotational shaft is changed to change the working point of the force acting between the moving plate and the casting media so that the crushing operation is possible. There is also an effect.
