Description

Chip recycling molding machine

The present invention relates to a device for collecting chips to be recycled when processing metal products (CHIP), and in particular, a chip recycling molding machine for forming a large amount of metal chips generated by silver debris into a large mass and easily molded into a melting furnace. It is about.

In general, in the process of processing a metal product by a machine such as a lathe or milling, a chip made of the same material as the metal product is generated, which can be recycled.

For example, in the process of manufacturing a basic article by casting and then processing the surface, for example, a process of manufacturing an aluminum wheel, for example, the manufacturing facilities have a melting furnace for melting aluminum alloy and injecting the molten metal into a mold There is a product molding machine for manufacturing a basic product and there is a surface processing machine for processing the surface of the manufactured basic article is to perform a series of work processes.

In the above work process, the casting process and the surface processing process are carried out in one place in order. The chips generated in the surface processing process can be directly put into the melting furnace to be dissolved, but the chips produced in the form of small debris are Since the chips thrown by the high pressure blowing that is strongly injected into the furnace are lost, there is a lot of loss. Therefore, the above method is not used.In order to recycle, the chips generated from the processing machine are collected and put in a moving box. The vehicle is transported to a regeneration-only factory located in a remote place and put into a regeneration furnace that is professionally recycled. Room to be transferred to the manufacturing plant Use the law.

In other words, the recycling process is carried out in a specialized recycling plant specializing in the recycling industry, which requires a separate recycling plant, which requires additional recycling costs, and there is also a loss of about 15% of chips that can be recycled in the recycling process. In particular, in order to prevent the change in the characteristics of the components contained in the foreign material such as iron in the process of transportation should be carried out a suitable refining process.

The present invention was devised to solve the above-mentioned problems. The method does not have a separate regeneration process in a factory having a unit manufacturing process in which a casting and processing process is performed in a series of steps in a facility of a factory. By reducing the loss of the chip to the maximum as well as not having a separate regeneration process to reduce the cost to be put into the recycling process to reduce the production cost.

As a process for obtaining the above results, the chips generated when the surface processing is performed after setting the basic goods completed by casting on lathes or milling, are directly collected and put into a regeneration compression molding machine equipped with a grinder to be formed into large chunks. When the chip is formed into a hopper, it is crushed more finely by the crusher installed at the lower side, and then gathered in the chip assembly, and when a certain amount is put into the compression molding machine, it is compressed to a certain size by the driving of the upper compression cylinder and discharged. The formed chip lumps are recycled by putting them in a melting furnace without special means of transportation.

According to this schematic process, the problem that the chips introduced into the furnace are blown off by the blowing air is minimized, and in particular, the process of minimizing the influx of material such as impurities or iron in the conventional transfer process, and the separate regeneration process By providing a molding machine that can reduce the cost by not doing.

It is to be pulverized more by (52), which is driven by the pulverizer motor 51 of the back, so that a pair of pulverizer 52 is engaged by the rotation to finely crush the chip 201 introduced between them.

The chip 201 pulverized as described above is collected in the lower chip assembly 40, which is pushed into the compression mold 90 on the front side by the transfer screw 42 installed on the lower side of the chip assembly 40. As the rotational drive of the transfer screw 42 causes the spiral movement by the rotation of the transfer motor 41 on the rear side, the chip 201 is pushed and moved so that the screw guide groove 97 of the forming frame 91 is moved. The chip 201 is introduced into the compression groove 93 of the compression mold 90 through the chip guide groove 97 of the molding die 90 and the needle supply hole 83 of the piston guide 80 installed on the upper side. .

At this time, the lower side of the compression molding die 90 is placed on the frame support 150, which is the discharge rod 142 of the discharge cylinder 140 connected to the back side is relaxed, the discharge side of the compression molding die 90 Due to the blocking, the chip 200 introduced into the pressing mold 90 is collected, and the cylinder rod 62 of the compression cylinder 60 installed on the upper side has a start switch located at the top of the operation switch 120. The limit 64 is brought into contact with the top dead center at 121 and the compression piston 70 connected to the lower side is inserted into the piston guide 80 to maintain the standby state.

At this time, the upper surface of the frame holder 140 has a height of the discharge direction "H '" and is rearward. As the "H" is formed to be inclined so that the rear portion is higher, so that the height of the upper surface of the frame support 140 is lowered as the frame support 140 is spaced apart, so that the friction force formed on the upper surface and the bottom of the chip lump 200 is reduced. Solved so that the frame support 140 can be spaced apart smoothly.

When the frame holder 140 is spaced apart from the discharge groove 152 of the compression mold 90 as described above, as shown in FIG. 11, the compression piston 70 moves downward to limit the discharge 64 to the discharge switch 123. The chip mass 200 compressed in the compression mold 90 is pushed downward to the contact position downward, and the friction force formed on the outer circumferential surface of the chip mass 200 and the inner surface of the compression mold 90 is compressed. The inner surface of the 90 is inclined wide toward the discharge groove 152 so that it is easily discharged without great resistance.

When the chip block 200 is dropped into the support hole 133 by the action of the compression piston 70 as described above, the discharge cylinder 140 operates as shown in FIG. 12 to transfer the frame support 150. If the original position in the direction pushes the chip block 200 dropped in the support hole 133 to fall to the discharge guide 131 is transferred to the melting furnace by the transfer means installed on the front side.
