Description

[Detailed Description of the Invention] This invention is a device that compresses lumps of cutting waste, which have strong properties like those of steel products, into a size that is easy to cut, and then cuts and eliminates them. This invention relates to an improvement of a device for facilitating the replacement work of the cutting blade.

Various types of metal cutting chips that are continuously cut out into long thin strips are cut into appropriate lengths and then disposed of are already available. However, although these devices are suitable for removing cutting waste from soft metal products such as brass and aluminum, some of them cannot be used to remove cutting waste from strong metal products such as steel products. Moreover, such tough cutting chips are rolled into long, thin pieces and collected into cotton-like nodules, but although the nodules are lightweight, the individual cutting chips are sharp and elastic. However, the elimination process required a great deal of effort. Therefore, the present inventors have already provided a device that compresses such cutting waste nodules to a size that is easy to cut, cuts them, and removes them as small pieces, but the blade for cutting the cutting waste nodules is hard. Even if the blade is made of metal, the cutting waste is strong, so the cutting power of the blade quickly decreases, necessitating its replacement.

The present invention aims to provide an improved mechanism for easily replacing the cutting blade in a device that compresses, cuts, and removes metal cutting waste lumps into small pieces as described above. It is something.

That is, the present invention includes a pair of rolls for compressing metal cutting waste nodules, a crank mechanism that intermittently rotates the rolls, and a cutting blade reciprocating mechanism for cutting the metal cutting waste nodules compressed by the rolls. , in the device for cutting and removing metal cutting waste, which includes a discharge hopper for receiving cutting waste cut by the cutting blade reciprocating mechanism, the roll is placed in a machine frame different from a machine case supporting the crank mechanism; A machine frame that supports the roll is rotatably supported around the shaft of an intermediate gear that engages with a gear attached to the shaft of the roll and receives intermittent rotation from a crank mechanism on the machine box. It is characterized by

In the embodiment shown in the accompanying drawings, the cutting and removal device for metal cuttings comprises several pairs (in this example two pairs) of compression rolls 1, 1, 2, as shown in dotted lines in FIG.
2, a cutting mechanism 3, and a hopper 4 for removing cutting waste.

The several pairs of compression rolls 1, 1, 2, 2 are attached to a machine frame 10 having a wall plate to prevent the cutting chips supplied to the rolls from scattering outside the apparatus. A cutting waste receiver 11 is provided protrudingly. This cutting waste receptacle 11 is a receptacle for carrying the metal cutting waste cut out by the machine tool into lumps of a specific size beforehand above the cutting waste receptacle 11, and dropping them onto the compression rolls 1, 1. When the cutting waste that has become a lump of enormous size is supplied to the waste receptacle 11, the cutting waste is transferred to the first compression roll 1,
1, it is compressed to a predetermined size.

In order to improve its compressibility, rolls 1, 1
On the circumferential surface of the rolls, small protruding ridges 13, 13, 13, . . . . . . . . . . It is arranged so that it is pressed between two parts. However, there is still a risk that the cutting waste nodules may not be compressed between both rolls 1, 1, so small protrusions 14, 14...... are provided here and there on the roll circumferential surface to ensure that the cutting waste nodules are transferred to both rolls. It is designed to be clamped between 1 and 1.

The distance between the first pair of compression rolls 1, 1 is such that the size of the cutting waste nodules is reduced to a certain degree. Therefore, if the compressed size allows cutting, only the first pair of compression rolls 1, 1 is required. However, if the supply to the cutting blade is still not possible with the compression size, the lower part of the compression rolls 1, 1 is interlocked with the second stage compression rolls 2, 2, and then the second stage compression rolls 2, 2. The machine frame 10 is equipped with three stages of compression rolls and compression rolls.

The cutting waste compressed into a lump of a predetermined size by the second-stage compression rolls 2, 2 is lowered at one end to a cutting mechanism 3 provided directly below the rolls 2, 2, where it is cut by a cutting blade. It will be done. The cutting blade consists of a fixed blade 30 and a movable blade 31, and is driven by a geared motor 6.
The movable blade 31 reciprocates toward the fixed blade 31 by a crank 60 driven by the crank 60 . Note that the crank mechanism 60 is not limited to the one shown in the drawings.

The chips cut by the cutting mechanism 3 fall into the hopper 4 directly below the mechanism 3, and are deposited on a damper 40 provided at the bottom of the hopper. The damper 40 is opened by the drive of the air cylinder 41, and the cutting waste particles fall into the air transport pipe 5 communicating with the bottom of the hopper 40, and the chips are subjected to a predetermined treatment by the air flow flowing through the transport pipe 5. Transported locally.

In the metal cutting waste cutting and removing device having the above configuration, in order to make it easier to attach and remove the cutting blades 30 and 31, the compression rolls 1, 1, 2, and 2 mechanism parts are simply removed from the cutting blade mechanism 3 part. A mechanism is provided for removal. That is, the first-stage compression rolls 1, 1 have gears 15, 16 attached to their shaft ends engaged with each other on the outside of the machine frame 1 that supports them, so that the cutting waste is compressed between the rolls 1, 1. Rotate to. In order to impart the rotation to one of the gears 15, an intermediate gear 17 that meshes with the gear 15 is provided, and the gear 17 is attached to the bottom on which the machine frame 10 is placed, although the detailed support mechanism thereof is not shown. It is attached to a shaft 18 supported by a bearing (not shown) on the upper surface of the side machine box 7, and is driven by a rod 61 provided on a crank 60 or another crank mechanism.
One-way rotation is intermittently applied via another gear 12 attached to the . The shaft 18 is connected to the machine frame 10
The lower right corner of each figure in each roll 1, 1, 2, 2
It penetrates in a direction parallel to the machine frame 10.
Grip the handhold portion 19 attached to the
When the machine frame 10 is lifted in the direction shown by the chain line in FIG. Repair work can be performed safely.

Note that a push-out plate 33 is provided on the movable blade 31 for dropping the cutting waste lumps that are about to be placed on the blade 31 into the hopper 4, and the push-out plate 33 is connected to the crankshaft 62.
is provided with another crank mechanism 63 (see dotted line diagram),
The crank mechanism 63 causes the movable blade 31 to move backward over the blade 31 during the cutting waste cutting process.

As described above, the metal cutting waste cutting and removing device of the present invention moves the compression roll that sends out compressed cutting waste aggregates to the cutting blades 30 and 31, and the machine frame 10 that supports the compression roll.
Since the entire intermediate gear 17 is reversed using the support shaft 18 as a fulcrum, the replacement and repair of the cutting blades 30 and 31, which tend to reduce the cutting force when cutting strong and rigid cutting chips, can be done safely, easily and quickly. After replacement or repair, the machine frame 10 can be returned to its original position and the cutting waste can be immediately removed, making it possible to create an excellent mechanism for removing cutting waste.
