Description

THE MACHINE FOR THE SELECTIVE WASHING OF THE SHEET

The invention relates to the metallurgical industry and can be used for stripping individual defects of rolled products.

A known machine for selectively stripping sheets, made in the form of a bridge, moving along guides over the processed sheets, on which there are guides for moving the carriage, as a result of which the grinding spindle receives movement in two mutually perpendicular directions.

Separate control of the longitudinal and transverse movements of the grinding wheel significantly increases the auxiliary time.

In order to improve the quality of processing, the mechanism for the vertical movement of the stripping head of the proposed machine is made in the form of a hinged parallelogram connected to the counterweight, whose lever is hinged in a flat guide rigidly connected to the stripping head.

Machine control is simplified by using a hollow handle with a spherical stone that interacts when the handle is tilted to one side or the other with two rack-and-gear mechanisms connected with the contactors of the speed-controlling regulators.

Longitudinal transverse movement of the stripping head is controlled by the handle I and pressing the stripping head to the sheet being processed by the lever 10. Supporting 11 n pressure 12 rolls serve to hold the sheets 13 being processed on the belt 4. The stripping wheel 14 is suspended on the four-bearing hinge 15 to the longitudinal carriage 6. 16 of the quadruple is connected to the guide 17. The cleanup head is raised by the counterweight 18. The vertical movement of the head is controlled manually or by means of a hydraulic cylinder 19. its faces interacting with the slats 21 four rack-and-pinion mechanisms 22, the levers 23 of which include a co-tact 24 of the speed regulators 25. The sheets 13 to be processed are laid on the belt 4 and the buttons 26 are transferred to the treatment zone by the movement of the button 26. Each time you press the button, the tape does not move 300 mm forward. The operator, having visually determined the location of the defect, rotates the handle 9 (at the same time it begins to move longitudinally 6 and transversely 5 carriages) until the stripping wheel 14 is above the defect. After that, the operator by pressing the lever 10 op; the RCT of the 7th 7kvku - addition of the source, makes a defect sweep. Clearing and producing at A on the head, in addition to longitudinal and transverse movements, also performs an oscillating GT1RP movement, which ensures good surface cleaning. After the defect has been cleared, the operator lowers the handle 10, and the head is detached from the sheet being processed by the action of the counterweight 18. Raising and lowering the cylinder head can be mechanized1 thanks to the hydraulic cylinder; 9, connected with the bolt, counterweight 18. In this case, the control is performed by the 1C console 27, the mouth, the hydraulic unit and the hydraulic unit. .

Zipper sheet

Gorlovka is treasured. Treated thin sheets have significant warpiness. In order to eliminate the clamp in the places of raising the profile of the sheet, the machine table is made in the form of a flexible endless rubber-fabric tape, which absorbs when increasing the cutting force. The subject matter of the invention 1. A machine for selectively stripping sheet metal, on the bed of which devices for transporting and a carriage with a stripping head are mounted, with an angle of 30 mm, so that, in order to improve the quality of processing, the mechanism of vertical movement of the stripping head is made in the form of with a counterweight of a hinged parallel - - i gram, the lever of which is mounted hinged but in a flat guide rigidly connected with a stripping head. 2. The machine according to claim 1, characterized in that, in order to simplify the control of the machine, the mecha, -g -.-gn base of the movement control of the wiper head is designed as a hollow handle with a spherical stone mounted on it, For example
