Abstract

PURPOSE:To have replacement and repair of a cutting edge safely, easily and quickly by inverting a compression roll of the metal swarf cut and exhaust device with the shaft of intermeidate gear as fulcrum with the whole machine frame. CONSTITUTION:A metal swarf cut and exhaust device is equipped with a mechanism to remove the mechanical parts of compression rolls 1, 2 easily from the cutting mechanism 3. That is, the compression roll 1 at the first stage rotates outside the machine frame 10 to support it while gears 15, 16 mounted on the shaft end are meshing with each other. This rotation is transmitted to the gear 15 through an intermediate gear 17. This intermediate gear 17 is mounted on a shaft 18 borne by a bearing at the oversurface of a lower machine box 7, on which the machine frame 10 is placed, and driven into single-directed intermittent rotation bt a crank 60 or a rod 61 installed in separate crank mechanism through gear 12 mounted on said shaft 18. This shaft 18 penetrates the machine frame 10, which is inverted to the position as shown by the dot-and-dash line in the attached illustration, by holding a handle 19 and lifting it in the direction as shown by dot-and-dash line. Now inspection and repair of cutting edges 30, 31 can be performed.

Description

[Detailed Description of the Invention] This invention is a device that compresses lumps of cutting waste, which have decorative properties like 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 products 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 decorative metal products such as iron products. Moreover, the cutting waste of such decorative parts is rolled up into a long and narrow state and concentrated into cotton-like nodule, but the nodule is only a small amount.
Individual cutting chips are sharp and elastic, and removing them requires 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. Although the cutter is made of metal, the cutting power of the cutter quickly decreases because the cutting waste is a decorative part, and it becomes necessary to replace the cutter.

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.

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

Several pairs of compression rolls 1, 1, 2, 2 are attached to a machine frame 10 with a wall plate to prevent the cutting chips supplied to them from scattering outside the apparatus, and the upper surface of the machine frame 10 is A cutting love 11 is provided protruding from the top. This cutting love 11 transports the metal chips cut out by the machine tool into lumps of a specific size to the upper part of the cutting love 11, and presses the compression roll 1,
The cutting waste, which has become a lump of enormous size, is supplied to the love 11. is compressed to a predetermined size.

In order to improve its compressibility, the surfaces of the rolls 1, 1 are provided with small protrusions 13, 13 and 13 along the axial direction of the rolls.
. . are provided protrudingly so that the so-called roll circumferential surface is not uneven so that the cutting waste lumps are reliably squeezed between both rolls 1°1. However, there is still a risk that the cutting waste lumps may not be compressed between the rolls 1, 1, so small protrusions 14, 14, etc. are provided here and there on the circumferential surface of the rolls to ensure that the cutting waste lumps are not compressed between the rolls 1, 1. It is designed so that it is squeezed between 1 and 2.

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 it is possible to cut the compressed size,
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 roll 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 is composed of a fixed blade 30 and a movable blade 31, and the movable blade 31 reciprocates toward the fixed blade 30 by a crank 60 driven by a gear motor. The rank 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 = 5-3, and are dumped into the damper 4 provided at the bottom of the hopper.
Deposit on 0. The damper 40 is opened by the drive of the air cylinder 41, and the chips fall into the air transport pipe 5 communicating with the bottom of the hopper 40, and the chips are transported to a predetermined processing location by the air flow flowing through the transport pipe 5. be transported.

In the metal cutting waste cutting and removing device having the above configuration, in order to facilitate the installation and removal work of the cutting blades 30, 31, the compression rolls 1, 1, 2, 2 are
A mechanism is provided for easily removing the mechanical parts. That is, the first-stage compression roll 1.1 has gears 15 and 16 attached to its shaft end engaged with each other on the outside of the machine frame 1 that supports it, so that the cutting waste is compressed between the rolls 1 and 1. Rotate to . In order to apply the rotation to one of the gears 15, an intermediate gear 17 that meshes with the gear 15 is provided, and the gear 17 has a detailed support mechanism that is not shown in the drawings. A shaft 1B supported by a bearing (not shown) is attached to the upper surface of the lower machine box 7, and the gear 12 is attached to the shaft 1B by a rod 61 provided on a crank 60 or another crank mechanism. One-way rotation is applied intermittently. The shaft 18 is
The lower right corner of each figure of the machine frame 10 is designated as each roll 1, 1.2,
Therefore, if you grasp the handhold part 19 attached to the machine frame 10 and lift the handhold part 19 in the direction of the chain line in FIG. As a result, the rolls 1, 1, 2, and 2 can be reversed to the positions shown in chain lines, and thus inspection and repair work on the cutting blades 30 and 31 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 a crankshaft 62 by another crank mechanism 6.
3 (see dotted line diagram), and the movable blade 31 is moved backward on the blade 31 by the crank mechanism 63 during the cutting waste cutting process.

As described above, the applied cutting waste cutting and removing device of the present invention uses the support shaft 18 of the intermediate gear 17 as a fulcrum to move the compression roll that sends out compressed cutting waste aggregates to the cutting blade 30, 31 together with the machine frame 10 that supports it. Since the cutting blade 30 is reversed, its cutting power tends to be reduced when cutting chips from decorative parts.
．． 31 can be replaced or repaired safely, easily, and quickly, and after the replacement or repair, the machine frame 10 can be returned to its original position and cutting waste can be removed immediately, making this mechanism an excellent cutting waste removal device. I was able to make it my own.
