In this creation, the outer ring of the steel coil is uncoiled by the roller saddle equipment, and then the outer ring of the steel coil is cut with an off-line shearing machine to reduce the loss of scrap steel.

Description

Scrap reduction device

This creation is about a scrap steel reduction device, and more particularly about an application of an off-line shearing machine to cut the outer ring of a steel coil.

When the existing inspection line produces reprocessed steel coils, it is necessary to go to the inspection line for sampling or removal of defects. During the upper inspection, the steel coils are rolled up from the uncoiler, and are lapped by the lapping machine. All steel coils need to be identified manually in the vertical inspection area and the The lap joints of the coils need to be coiled into small coils (Pup coil), and then the remaining coils should be re-inspected and re-coiled. Therefore, each coil on the upper inspection line has a loss of 500~1500kg.

In view of this, this creation proposes a scrap steel reduction device, which can reduce the amount of scrap steel cut off by cold-rolled steel coil reprocessing and reduce scrap steel loss.

In order to achieve the above-mentioned purpose, the scrap steel reduction device of the present invention comprises: a shearing machine, which is arranged downstream of a roller saddle; and a waste platform, which is arranged downstream of the shearing machine.

In an embodiment of the present invention, the waste platform is designed in the form of a long cylindrical rubber wheel, and a bakelite board is arranged on it to carry the cut steel strip.

In an embodiment of the present invention, the shearing machine includes an upper circular cutter and a lower circular cutter, which are driven by a motor to cut the steel strip.

In an embodiment of the present invention, the front end of the shearing machine is provided with a feeding guide device, the angle of which can be adjusted to facilitate the feeding of the steel strip.

In an embodiment of the present invention, the front end of the feeding guide device is provided with a guiding telescopic plate, which is driven by a motor, and the telescopic distance can be adjusted according to the size of the steel belt, so as to facilitate the feeding of the steel belt.

In order to reduce the reprocessing of cold-rolled steel coils, only a small length of test piece or scrap steel is removed from the outer ring of the steel coil, so as to increase the yield of the finished product. The outer shearing machine cuts the outer ring of the steel coil to reduce scrap loss.

In order to make the above and other objects, features and advantages of the present invention more apparent, the following detailed description will be given in conjunction with the accompanying drawings. In addition, in the description of this creation, the same components are represented by the same symbols, which are described above.

Referring to FIG. 1 , a shearing machine 100 is added outside the line of the scrap steel reduction device of the present invention, which is located at the north position of the strip demolition machine and downstream of the cradle roll 190 . In addition, a waste platform 180 is provided downstream of the shearing machine 100 .

Referring to FIG. 2 , the shearing machine 100 is provided with an upper circular cutter and a lower circular cutter, which are driven by the motor 110 to cut the steel strip. The front end of the shearing machine 100 is provided with a feeding guide device 120, the angle of which can be adjusted to facilitate the feeding of the steel strip. The front end of the feeding guide device 120 is provided with a guiding telescopic plate 130, which is driven by a motor, and its telescopic distance can be adjusted according to the size of the steel belt, so as to facilitate the feeding of the steel belt.

Please refer to FIG. 3 , the waste platform 180 is designed in the form of a long cylindrical rubber wheel, and a bakelite board 182 is provided on it.

Referring to FIG. 4 , after the steel coil binding band is cut off, the existing roller saddle 190 equipment outside the line starts to rotate to unwind the steel coil 192 . The way of uncoiling the steel coil 192 is to press the outer ring. When the head end of the steel coil 192 is passed through to the outlet of the shearing machine 100, the test piece is cut according to the sampling length. If it is only because the weight limit of the finished product exceeds the limit, the excess weight will be cut off. The cut steel strip is fed to the bakelite board 182 of the scrap platform 180 .

According to the scrap steel reduction device of the present invention, the off-line shearing machine 100 is operated by an operator through a human-machine operation interface, and the action of the shearing machine is controlled by a programmable logic controller (PLC).

In order to reduce the reprocessing of cold-rolled steel coils, only a small length of test pieces or scraps from the outer ring of the steel coil are removed to increase the yield of finished products. The cutting machine cuts the outer ring of the steel coil to reduce the loss of scrap steel.

Although this creation has been disclosed by the foregoing examples, it is not intended to limit this creation. Anyone with ordinary knowledge in the technical field to which this creation belongs can make various changes and modifications without departing from the spirit and scope of this creation. Therefore, the scope of protection of this creation should be determined by the scope of the appended patent application.
