Abstract

PURPOSE:To remove stuck slag and flashes easily by passing flat products attached with slag and flashes after gas cutting between plural sets of splined upper, lower rolls, spirally grooved upper, lower rolls and straight rolls. CONSTITUTION:Flat products stuck with oxide slag and flashes around cut ports by gas cutting are first forced into between splined lower rolls 6a and upper rolls 10a by a conveyor 46. Here, the plural upper rolls 10 and the rolls 6 are rotated respectively at different numbers of revolutions by a motor 12 and the latter by a motor 14. The rolls 10 are pressed to the rolls 6 by means of compression springs 30. The slag and flashes of the products are stripped from the products by the differences in the rotating speeds between the rolls 10a and 6a. In succession, the products pass between upper, lower rolls 10b, 6b, and the slag and flashes are forced into the spiral grooves by the compressive forces of the springs 30. Further, the shapes and strains of the products are corrected by upper, lower straight rolls 10c, 6c and the products are removed through a chute 48.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for removing oxidized slag and burrs from flat products after gas cutting.

Conventionally, in gas cutting, oxidized slag and burrs (hereinafter referred to as slag, etc.) adhering to the area around the cut after gas cutting are removed manually using a casting spatula or hand grinder. Alternatively, it is generally removed mechanically using a belt grinder or tumbler. However, the former manual methods are both time-consuming and physically tiring, making them inefficient.

In addition, the latter method using a medium-belt grinder, which uses mechanical means, is difficult to adjust the grinding allowance, so the grinding tends to be too much or too little, and it is necessary to perform back-to-back grinding. This method removes syslag etc. by colliding products with each other directly or through an anti-friction material in a rotating container. In reality, both methods are impractical and are not used very often, as they are not only limited by the above, but also create scratches due to collisions between products, which significantly degrades product quality.

The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional art, and for this reason, the slag etc. removing device according to the present invention includes a base and a plurality of shaft-supported slags that are spaced apart along the longitudinal direction of the base. a lower roll; a plurality of roll heads disposed on the base at intervals along the longitudinal direction of the base and elastically supported on the base so as to approach and move away from the lower roll; and a lower roll supported pivotally by each roll head; a plurality of upper rolls arranged opposite to each other;
The present invention is characterized in that it includes a drive means that rotates the upper roll and the lower roll at different speeds, and the product to be processed is carried between the upper roll and the lower roll.

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

It consists of 14.

The lower roll 6 is attached to the machine base 4 by fixing the roll support 4 which includes a pair of left and right parallel side plates on the base 4α, and attaching the roll surface between the parallel side plates of the roll support 4b'. The lower roll 6 is pivotally supported so that it is slightly exposed on the roll support stand.

One end of each lower roll 6 extends to the external force of one Q side plate of the roll support base 4b (FIGS. 2 and 8), and a sprocket (16) is attached to the extended portion, and each sprocket 16ii They are connected by a common chain 17 (FIG. 2). The lower roll at the rearmost part of the machine base 4 is provided with a rotating force of a motor 14 fixed to the machine pace command through a sprocket 18 and a chain 20 (Fig. 1), and thereby the lower roll The rolls 6 are rotated by a motor 14 at the same speed. For reasons to be described later, the lower roll 6 has a spline roll 66 provided with a plurality of axial grooves on the roll outer periphery as the roll 6α at the front end of the machine base 4, and a spiral grooved roll with spiral grooves provided on the roll outer periphery, and the base It is desirable that the plurality of (eight in the figure) rolls 6G in the rear portion be constituted by straight rolls whose outer periphery has a cylindrical surface.

Incidentally, an auxiliary roll 22 is provided between each roll to prevent the product from falling and to ensure smooth feeding.

Each roll head 8α, 8b, 8c to the machine base 4
To install the roll support 4b, a plurality of vertical supports 24 are erected on the base 4α on both sides of the roll support 4b, spaced apart in the longitudinal direction of the base, and the support 24 is installed on each side of the roll support 4b.
4 upper ends are mutually connected to the longitudinal member 26 to form a support rod 27, and the longitudinal members 2-6 of the support frame 27 and the horizontal cross-section parts fixed to the upper surface of each roll head 8α, 86% 8C letter d
The bracket 28 (FIG. 8) is attached to the machine base 4 so as to be constantly pressed against the lower roller 6 by interposing compression springs 80 between the bracket 28 and the leg portions 28α on both sides. Each of the roll heads 8α, f3b, and F1a includes a pair of left and right parallel side plates that pivotally support a plurality of upper rollers 10, and one end of each upper roller 10 extends as far as the external force of one of the side plates, similar to the lower roller. (FIG. 8) A sprocket 82 is attached to each of the extensions, and each sprocket 82 is attached to a common chain 84 (a second chain) for each roll head.
Each head 8α, 8b1 is connected by
A rotational force is applied to the intermediate front upper roller of the plurality of rollers 10 of 8C by a motor 12 installed on the bracket 28 via a sprocket (not shown) and a chain 40. Upper roller 1O

By dividing 6 into roll heads 8α, 8b1, and 8G, it is possible to prevent product play inside the device and idle rotation of the rolls when products are continuously fed between the upper and lower rolls 1016, and to separate each roll head. The effect of peeling off slag, etc. can be further enhanced by varying the rotational speed of the rolls. In addition, by pressing the Rads 8G and 8b18C downwardly using the compression springs 80 and pressing the upper roller 10 against the lower roller 6, the upper and lower rollers 10°6 crush and peel off the slag and burrs. It is possible to increase the force and prevent the product from being unloaded.

By utilizing the elasticity of the spring 80, it becomes unnecessary to adjust the height of the roll heads 8α and 8b18C within the elastic range. In order to adjust the height position of the roll heads 8α and 8b18G for products that exceed the expansion and contraction range of the compression spring 80, a receiving plate 42 that can support the upper end of the spring 80 is provided on the lower surface side of the longitudinal member 26. is adjustable and fixed to the longitudinal member 26 by bolts and nuts so that its height position relative to the longitudinal member 26 can be changed. As shown in the figure, the pair of left and right receiving plates 2 are attached to the pole heads 8α, 8b, and 8c, which are connected to each other by a horizontal member 44 (FIG. 2) in order to reinforce the support frame 27. For reasons to be described later, the upper roller IO that is supported by the shaft is a roll with a spline groove so that the frontmost roll IOZ of the roll head 8α at the frontmost position of the machine base matches the lower roll, and the rest of the frontmost roll head 8a is and the roll of the intermediate roll head 8b are spirally grooved rolls lOb,! :', and it is desirable to configure it as a straight roll in accordance with the 1 octave lower roll of the rearmost roll head 8C.

In addition, a product conveyor 46 is installed at the front of the device at the same height as the lower roll 6. is installed and a gas cutting device (not shown) is installed.
The product discharged from the machine is automatically fed into the device. Further, a chute 48 is mounted on the rear surface of the apparatus for automatically feeding the processed product into a product transport box.

Next, the operation of the apparatus of the present invention will be described. The product conveyed by the product conveyor 46 is separated from the product due to the difference in rotational speed of the upper and lower 1'-rules 10α and 6α of the splice H. The product that has passed through the spline grooved roll lOα, 6a is drawn in by the adjacent upper and lower spiral grooved ports 106, 66, and every time it passes through the spline grooved roll 106, 6b, it adheres to the product and 9 slugs and notches are attached to the spring 8.0. Due to the difference in rotational speed of the upper and lower rolls, the slag and debris that are pushed into the spiral monument by the compressive force of It is forcibly moved and peeled off. The product that has passed through the spiral grooved roll 106°abjr is then passed through the lower straight rolls 1Oc, 6c group to correct the distortion of the product in the same manner as the white roll repeller.
Thereafter, the product is automatically placed into a product transport box (not shown) by the shooter 48, and the work is completed.

In the above embodiment, the upper and lower rolls are made of steel, but the rolls may be made of noodle material as long as they have sufficient strength and durability. In addition, although the rolls are driven using a chain and sprocket mechanism in the device of the embodiment, by using a gear drive, power transmission can be made more reliably and smoothly. The number of motors can be reduced by changing the driving force. Furthermore, in the example device, bolts and nuts are used to adjust the gap or pressure between the upper and lower plates, but by automatically raising and lowering the sill roll head using an automatic hydraulic adjustment mechanism, changes in product plate thickness can be easily adjusted. and can automatically respond to changes in set pressure. Furthermore, by additionally installing a roll repeller machine, a grinding roll, a wire flange roll, etc. to the apparatus of the embodiment, even higher quality processing can be performed.

As described above, according to the present invention, it is possible to mechanically and automatically remove slag and debris from a product after scraping, without physical fatigue, and to improve product quality. A slag etc. removing device can be obtained that can be applied to products of a relatively wide range of sizes and shapes without causing any damage.
