[Industrial applications]

 The present invention breaks, crushes, breaks, etc. cast products, dams, feeders, sluiceways, and other cast product wastes (hereinafter simply referred to as casting wastes) (hereinafter referred to as crushing). The present invention relates to a crushing tool for casting waste, etc.

[0002]

[Prior art]

 Conventionally, the methods of crushing cast product waste are generally classified into the following two methods. First, there is a method of using a relatively large machine or device that is automatically and in large quantity through a crusher (shreetter). Next, there is a method in which a relatively small tool or device is used, which has a structure in which a small amount is manually operated through a hitting tool such as a breaking hammer and a crushing machine such as a breaking breaker.

As a casting weir folding, riser folding, and runner folding machine, various tools usually called packers such as a casting weir crushing tool, a casting weir cutting and separating machine, and a sprue crusher are available. Although it is commercially available, the purpose is to cut unnecessary weirs, runners, etc. from cast products, or to cut multiple cast products into individual cast products, as described above. Has a different field of use from the present invention.

[0004]

[Problems to be solved by the device]

 In the above-mentioned crusher (or crusher), the size of the crusher becomes large and its use or installation range is limited. , It is not suitable for easy and convenient crushing, and the cost burden is also large, and there is a problem in recent years that rationalization and saving money are avoided. . Also, with this type of large-scale equipment, it is not possible to use the flexible method of simply moving to the place where the casting waste is collected and performing the crushing work at the moving place. Limited range.

On the other hand, the crushing method using a tool or the like is simple, but has many problems to be solved in terms of work efficiency, work environment, and the like.

[0006]

[Means for Solving the Problems]

 In view of the above, the present invention has an object to be compact and flexible, to be used in any place, or to provide an optimal crushing tool for various aspects such as work efficiency and work environment. The following configuration is adopted as

The crushing tool for casting waste or the like according to the present invention is provided with a pair of fixed blades provided downward at the tips of frame bodies juxtaposed at appropriate intervals and capable of coming into contact with and separating from the fixed blades. And a sliding blade located substantially in the center of the fixed blade, a sliding frame that moves back and forth in the space between the frames in which the sliding blade is provided, and the frame that controls the longitudinal movement of the sliding frame. It consists of a hydraulic cylinder installed at the rear end of the body and other drive devices such as cylinders.

[0008]

[Action]

The operation of the present invention will be described below. The breaking tool of the present invention is suspended by a suspending rod whose upper end is connected to a gravity balancer (not shown), and is freely moved up and down or moved. Therefore, when the hanging rod is grasped to move or move up and down, and the casting waste is put in between the fixed blade and the sliding blade of the crushing tool as shown in FIG. It is placed between the fixed blade and the sliding blade, and maintains its original shape as shown in Fig. 6 (a). In addition, in the structure in which the crushing tool is provided with a foot handle, either or both of the foot handles (ideally considering stability) is used as a foot in order to stabilize the crushing tool. Step on and install the crushing tool stably on the floor.

After that, when a driving device such as a hydraulic cylinder or a pneumatic cylinder is operated to move the sliding blade forward, the lower portion (skirt) of the sliding blade has a blade edge with a gently curved surface in plan view. Therefore, the casting waste is reliably and sequentially broken, and further, the forward movement of the sliding blade pushes up the casting waste sequentially above the sliding blade (at the base), and as shown in FIG. As shown in (b), the casting waste is bent into a substantially V shape in plan view. It should be noted that, since the upper part of the sliding blade has a sharper mountain-shaped cutting edge than the lower part, it can be reliably and smoothly formed between the fixed blade and the R surface of the fixed blade as described later. It has a structure that breaks things.

The casting waste, which is bent into a substantially C-shape, is further pushed upward by the forward movement of the sliding blade, and reaches the R surface provided above the fixed blade. That is, it reaches between the mountain-shaped cutting edge above the sliding blade and the R surface of the fixed blade, and is ready to be broken at any time. Then, when the sliding blade is further advanced, the above-mentioned almost C-shaped casting waste is generated reliably and with less noise due to the mountain-shaped cutting edge and the cutting edge provided on the R surface. It can be crushed without. For example, the state shown in Fig. 6 (c) is reached, and the intended purpose can be achieved sufficiently. Then, when the sliding blade at the forward limit is retracted, a series of crushing work ends here.

When the crushing work is completed as described above, the next casting waste is applied. For example, a crushing tool is lifted by a gravity balancer and positioned above the next casting waste, and then the crushing work of a small number or a large number of casting wastes is sequentially performed through the same operations / operations and procedures as described above. do. The procedure of the crushing work described above is an example, and it goes without saying that the procedure is not limited to the example described above. Further, the size and / or power of this tool is appropriately changed depending on various types of objects to be crushed, such as casting waste, other waste, or other objects to be crushed.
