(54) DEVICE FOR POLISHING THE SHEET SURFACE

one

The invention relates to mechanical engineering and can be applied in the finishing processing of sheet metal.

 a device for polishing parts with a surface containing a mechanism for interchanging parts and means for applying various components of the polishing mixture to the cutting zone 1.

It. The device has limited technological capabilities due to the inconsistency of the movement of the parts and the feeding of the components of the polishing mixture to the cutting zone.

It is also known a device for polishing a surface of a sheet, comprising a drive for longitudinal feeding of the sheet, a container for the components of the polishing mixture, and a mechanism for applying the components of the polishing mixture to the surface of the sheet, each of which is designed as a kinematically connected roller with a drive installed in the container, and in contact with the flexible tape roller 2 ..

This device also has limited technological capabilities, since the mechanisms for applying the components of the polishing mixture have no means for reconfiguration.

The aim of the invention is to extend the technological capabilities of the device.

5 -This goal is achieved by the fact that each mechanism for applying the components of the polishing mixture is equipped with two drums, the axes of which are directed at an angle to the sheet feed direction, while the Q bend tape is fixed on the drums and is made with several sections of different widths.

The device has a frame 1, a drive 2 of the longitudinal feed of the sheet 3, the feed rollers 4, above which the rollers 5 are pressed, ie the rollers 5, as well as the mechanisms 6 and 7 of carrying the polishing components on the surface of the sheet 3.

The mechanism includes a container 8, filled with oil 9, in which it is immersed, kinematically connected by means of a chain transmission to one of the feed rollers 4, a roller 10 that is in contact with a flexible belt 11 in several sections, made with several sections of different widths. Each of the ends of the tape is fixed on the drums 12 and 13. The tape is secured by the clips 14 from the reversing. On the inclined side of the tank 8, a felt curtain 15 can also be attached to ensure an even flow of oil 9. The mechanism 7 for applying the polishing compound component contains a container 16 filled with abrasive powder 17, in which it is partially immersed, kinematically connected by means of a chain transmission to one of the feeding rollers 4, the roller 18, made, for example, with pockets 19 longitudinally along the entire length. On the inclined side of the container 16 A flexible tape 20 is provided, made with several sections of different widths, which is prevented from being bent by the clamps 21. Both ends of the tape are fixed on the drums 22 and 23. Each of the drums 12, 13, 22 and 23 is mounted freely on the axles 24 with the possibility of braking with a block 25, pressed against the drum by a spring 26. To treat the sheet surface serves the head 27. The device operates as follows. Before starting the device, mechanisms 6 and 7 apply the components of the polishing mixture to the sheet surface at the desired width. For this, rotating one of the reels 12 or 13, the tape 11 is rewound and, thus, i adjusts the length of the contact area of the tape 11 and the roller 10, i.e., adjusts the length of the lubrication section of the sheet. Similarly, rotating one of the reels 22 or 23 and rewinding the tape 20, regulate the length of the section where the gap between the tape and the roller 18 is 0.5-3 mm, and thus regulate the length of the section sprinkled with abrasive powder. Since the reels 12, 13, 22 and 23 are braked, the belts 11 and 20 are tightened. After that, the sheet 3 to be processed is fed into the feed rollers 4 and further to the treatment zone. In this area, where the tape 11 contacts the roller 10, when the latter is rotated, the tape 11 selects the oil deposited on the roller (it is partially immersed in oil 9, which fills capacitance 8). Oil, stack on the tape 11 and further along the inclined side of the container 8, falls on the felt curtain 15 and permeates it. The sheet 3 is moved, comes into contact with the shutter and the oil from it is transferred to the surface of the sheet. In the area where there is a gap between the belt 11 and the roller 10, the oil adhering to the roller is again transferred to the container 8. Next, the sheet 3 is fed to the abrasive powder application area. In the area where the gap between the belt 20 and the roller 18 is 0.53 mm, the powder that filled the pockets 19 (the roller is partially immersed in powder. 17) is poured out of them when the roller and pad are turned on the ribbon and further to the inclined side of the container 16 falls on the sheet 3. In the area where the gap between the belt 20 and the roller is more than 3 mm, the powder, spilling out of the pockets 19, falls back into the container 16. After sprinkling with powder, sheet 3 is fed by rollers 4 and 5 into the treatment zone. Thus, the device has wider technological possibilities, as it allows reducing the labor intensity and improving the quality of finishing sheets of various widths, while not using extra polishing mixture. Apparatus for polishing a surface of a sheet, comprising a longitudinal feed drive for a sheet, a container for components of a polishing mixture, and mechanisms for applying components of a polishing mixture to a surface of a sheet, each of which is made in the form of kinematically connected with a drive for longitudinal feed of a roller installed in a container, and in contact with the roller of the flexible tape, characterized in that, in order to improve the technological capabilities, each mechanism for applying the components of the polishing mixture and is equipped with two drums, the axes of which are directed at an angle to the sheet feed direction, while the flexible tape is fixed on the drums and made with several sections of different widths.
