Description

[Detailed explanation of the invention] This invention is based on the use of chips, especially turning chips (commonly called shavings).
This invention relates to a device for pressurizing and solidifying materials such as materials.

Conventionally, this type of device, the so-called briquetting device,
As shown in FIG. 1, two large rolls B each have a large number of mold holes A arranged on their circumferential surfaces.

Rolls B and B are rotated continuously at a constant speed while facing each other, chips are thrown between the rolls B and B, and the opposing image forming holes A are formed.
A device that molds briquettes with A is generally used, but in order to generate a large pressing force with this conventional device, it is necessary to increase the radius from the rotation center O of roll B to the molding hole A. As a result, the diameter of roll B increases, which increases the equipment cost and makes it difficult to move.Furthermore, since the large roll is rotated, power consumption increases. Become.

Furthermore, since the rotation of the roll during each process of chipping, pressurizing, and discharging remains constant during one cycle, the pressurization time after chipping is constant, and good solidification cannot be achieved. There were some drawbacks, such as:

The purpose of the present invention is to eliminate the above-mentioned drawbacks. Namely, one end is rotatably supported in the vertical direction, and the other end has a mountain-shaped mold hole 5 connected to the chip receiving surface. By operating a pair of arm-shaped molding plates 1 with mold holes facing each other,
A coupling mechanism installed to open and close the mold hole and interlocking them; a cylinder device associated with the mechanism that simultaneously operates the defining mold plate in the vertical direction; and a cylinder device configured to supply chips between both receiving surfaces. The invention is characterized in that it is provided with a means for.

Next, embodiments of the present invention shown in FIGS. 2 to 6 will be described.

Reference numeral 1 denotes an arm-shaped molded plate, one end of which is rotatably supported by a support shaft 3 provided on a machine base 2, and the other end is adapted to rotate up and down.

Moreover, the other end surface of the molded plate 1 is formed into an arcuate surface 4 centered on the support shaft 3, and a mold hole 5 is formed in the center thereof, and the arcuate surface at the top of the mold hole serves as a receiving surface. It consists of

The molded plate 1 is provided with a pair of arcuate surfaces 4, 4 closely facing each other.

Reference numeral 6 denotes a hydraulic cylinder for rotating the forming plates 1, 1. A connecting plate 8 is fixed to the lower part of the piston rod 7, and a horizontal elongated hole 9 is formed in the connecting plate 8. A pin 10 fixed to the plate 1.1 is loosely fitted into the elongated hole 9, and as the connecting plate 8 moves up and down, the forming plates 1, 1 are rotated up and down together.

Reference numeral 12 denotes a guide plate for the connecting plate 8, which is fixed to the support column 13.

14 is a balance spring installed between both molded plates 1,1.

Reference numeral 15 denotes a chip pushing rod, which is arranged such that its lower end is located above the mold holes 5, 5 of the two bottom mold plates 1, 1, and its upper end is connected to the piston of the hydraulic cylinder 16. ing.

17 is a conveyor for transporting chips, and 18 is a hopper for supplying chips, the lower end of which can supply chips to the mold hole 5.

19 is a chute for discharging briquettes made of solidified chips, 20 is a receiving tray thereof, and 21 is a water and oil discharge gutter.

Next, pressurized solid work will be explained.

First, the chips 22 are sent from the conveyor 7, and the chips 22 are supplied to the hopper 18, and the hydraulic cylinder 6 is actuated to move the piston rod 7 upward.
1 to open each opposing surface as shown in Figure 2A,
Chips are supplied into both mold holes 5, 5 through the receiving surface.

Next, the cylinder 16 is actuated and the pushing rod 15 is moved downward to push the chips into the mold holes 5,5.

Next, after the pushing rod 15 is moved upward and retracted, the cylinder 6 is operated to move the piston rod 7 downward, and the forming plate 1,
1 is moved downward to pressurize and solidify the chips in the mold holes 5, 5.

Next, the piston rod 7 is further moved down to rotate the definition forming plate 1.1 downward, the mold holes 5, 5 are opened, and the briquettes 23, which are solidified chips, are discharged.

The discharged briquettes 23 are transferred from the chute 19 to the saucer 2.
0, and the water and oil mixed in the chips are squeezed out and discharged from the discharge gutter 21.

After this pressurized solidification work is completed, the piston rod 7
Return to the upward movement and repeat the same operation as above to continuously form briquettes.

In the above processing operations, as the forming plates 1, 1 move from the open state shown in FIG. 2A to the closed state shown in FIG. 2B, the pressure against the chips in the mold holes 5, 5 gradually increases. , the resistance force of the molding plates 1, 1 against the rotational force gradually increases, the rotational speed of the molding plates 1, 1 at the time of maximum pressure on the chips is reduced, and the time for applying pressure on the chips becomes longer.

Therefore, the chips are reliably pressed and solidified.

As described above, in the present invention, since the molding plates 1, 1 are made into an arm shape, the radius from the pivot point to the mold hole 5 is the same as that of the conventional roll B to provide sufficient pressing force. Even so, compared to the conventional roll B, the length of the molded plate 1 of the present invention is only half, and therefore, it is smaller than the conventional one, the equipment cost can be reduced, and it can be easily moved.

Moreover, the pressurizing work can be performed using a small motor that operates the hydraulic or pneumatic pressure of the cylinder, and the power consumption can be lower than that of the conventional large motor that rotates the large roll B.

Furthermore, by operating the forming plates with a cylinder device, the forming plates 1, 1 gradually reduce their rotational speed as the pressurizing resistance increases, and the pressurizing time at maximum pressurization is lengthened, thereby reducing the amount of chips. It is practically effective as it can ensure solidification.
