Description

DETAILED DESCRIPTION OF THE INVENTION "Field of application of the technology" The present invention is applied to metal or non-ferrous metal parts.
) Regarding a crushing device that crushes into small pieces.

F'Prior art" A sprue 5, a runner 6, a weir 7 and a weir 8 are formed in the upper mold 2 and lower mold 3 in the mold 4 using foundry sand, for example, in the molding flask 1.
(See Figure 5) Molten cast iron (hereinafter referred to as molten metal) is placed in the sprue 5.
When poured, the molten metal passes through the runner 6 and the weir 7 and flows into the mold 4, and then when it reaches the nozzle 8, the supply of the molten metal is stopped.

A weir, a runner, and a sprue are integrally molded into the cast product, which is taken out from the flask 1 after cooling and solidifying.

Cast products and accessories such as runners (also called scrap).
After completely separating the runners and other accessories, when they are put into a small cupola or electric furnace at 2 to 3 T/H and a diameter of 600 to 700 to remelt them, they get tangled in the cupola and electric furnace. A so-called shelf hanging phenomenon may occur.

In order to avoid this phenomenon, the required size was crushed by dropping a weight such as an air press or a vibrator.

F(Jt) can be easily broken manually with a hammer, but it is inefficient and dangerous if handled incorrectly.

Air presses or pyrenes are efficient, but they are dangerous because they scatter.

However, recent castings include ductile cast iron (spheroidal graphite cast iron), that is, FCD 40-7o scrap that cannot be broken with the power of a hammer.

Also, instead of manual labor, machines such as air presses or pilens are inefficient.

"Object of the invention" Technical all of the claimed invention! The problem is that the shapes of the scraps are complicated, and some of them are relatively long.
To provide a crushing device capable of crushing to the required FIT size and easily taking out all crushed scraps.

"Structure of the Invention" In order to solve the above-mentioned technical problem, the structure of the present invention, that is, the technical means is a crushing device that crushes gold of any shape or non-ferrous metal into a required size by a pressing member that advances inside a casing. , at least two or more receiving blades are provided on the front wall of the casing, the receiving blades are horizontal, and the suppressing member is provided with at least one pressing blade positioned relative to the blades. , the crushing device is characterized in that a bottom wall VC between the suppressing member and the casing front wall is formed with a lower blade.

"Effects of the Invention" In addition to the above technical means, the scraps such as runners thrown into the casing are pushed forward by the pushing blade of the advancing suppressing member, and the scraps between the receiving means are pushed forward by the pressing blade and the receiving part. The pieces are crushed into 2 to 3 pieces by the blade, and the advance of the pressing member is temporarily stopped. When the pressing member is moved back, the pieces above the edge collapse downward, and the pressing member is moved forward again, that is, pushed 2If. In particular, scraps that have not yet been crushed are finely crushed.

Therefore, even if scraps such as runners are put into the cupola together with other dissolved forest materials, the primary effect is that undesirable phenomena such as hanging can be avoided. There is a secondary effect that makes it even better than before.

In addition, the scrap crushed inside the casing can be caused to fall into the packets or belt conveyor below by reversing the bottom cover provided on the bottom wall, which is a feature unique to the present invention.

180.180 is a protrusion formed at the upper part of the receiving blade 140r&i1 of the front wall 141 between the suppressing member 146 and the pusher blade 147, and the protrusion 180 allows the scrap to escape (the pusher blade moves upward). (Rise up.) Can be completely prevented.

``Operation'' Insert all the scraps such as runners into the recess of the casing.
The top lid 171 then moves forward to cover the opening of the casing.

Next, when the suppressing member 146 moves forward together with the piston rod 151, the pushing blade presses the scrap between the receiving blades, folds or crushes it into two or three pieces, and the crushed pieces are removed from the movable bottom cover 157. It falls into a packet (not shown) provided on a lattice base or onto a hook conveyor.

Next, when the entire pressing member 146 is moved a little, the scrap will collapse to some extent.

When the pressing member 146 is then advanced again, most of the uncrushed scraps are crushed.

At the same time as the suppressing member is retreated, the movable bottom cover 157 is reversed and opened by the operation of the lever mechanism.

As mentioned above, the crusher for scraps such as runners, which was one of the inefficient works in the past, can be carried out efficiently by using the device of the present invention, and there is no danger of iron pieces flying off during the work. At the same time, there is no unpulverized scrap in the crushed scrap, and it is now possible to convey the sorted scrap to the cupola using a conveyor, making efficiency even higher than before.

Further, since both sides of the suppressing member move forward while being guided by the guide bar, there is no need to lift up the holding member by scraps, and the intended purpose can be achieved.

Furthermore, although a hydraulic or pneumatic cylinder is described as one of the embodiments of the drive device with a pressing part, the drive device is not limited to this embodiment, and may include a drive device that combines a cylinder mechanism and a toggle link mechanism. etc. can be used.

In this case, all four guide bars (pillars) are required to fully guide the pressure plate.

FIG. 4 is a front view showing another embodiment of the present invention, which differs from the above embodiment in that crushed scraps are automatically transported to a separate bag, and a movable bottom cover 157 (bottom There is an operating mechanism VC for the (also called door). Bottom cylinder 18
A piston rod 183 whose base s of No. 2 is pivotally attached to the cylinder mounting seat 154 and reciprocates within the bottom cover cylinder 182.
The tip of the arm 184 is pivotally connected to one end of the arm 184.
The 0 base is pivotally connected to the boss 186 of the movable bottom cover 157.

Therefore, as the piston rod 183 retreats (1 l) from the switching trap for the pressure oil supplied to the bottom lid cylinder 182, the movable bottom lid 157 Fi is reversed, and the scraps fall onto the apron conveyor 185.

The scraps that have fallen onto the apron conveyor are carried to a separate bank 187 and stored therein.

Note that the scrap input into the device of the present invention is not limited to castings, but also other metals, non-ferrous metals, bronze,
Even brass? iiF! I have the same effect and effect as the one with the degree.
