Description

(54) YEARCHEAR GRINDER

one

The invention relates to welding technology and can be used to strip a weld on metal strips.

A known incisor reamer for stripping the seam of butt-welded metal strips, contains a frame with guides and a movable part mounted on them, made in the form of a carriage with two levers, one of the levers being pivotally connected with a scraper, and the ends of the levers on one side are connected to a drive their information, and on the other hand, are provided with support rollers and cutters for stripping the seam on both sides 1.

The purpose of the invention is to increase the productivity and quality of stripping the seam.

This is achieved by the fact that one of the levers is rigidly connected to a carriage equipped with two pairs of rollers installed with a clearance in the C-shaped guide frames, the front rollers being located near the center of gravity of the moving part, and the rear rollers are mounted on an eccentricity axis.

FIG. 1 shows a incisor incisor in the rest position before stripping; FIG. 2 is the same, section along the line A — A in FIG. 1 (the dotted line shows the position of the support rollers and rollers of the carriage when cleaning the seam); in fig. 3 - the same, section along BB in FIG. 2.

The incisor reamer includes a carriage 1 with lever 2 rigidly connected with it and lever 4 pivotally mounted on axis 3, at whose ends the supporting rollers 5 and cutters 6 are fixed opposite each other at the opposite end of the lever 4, pivotally mounted cylinder 7, stem which is pivotally connected to carriage 1,

Claims (1)

A pair of front 10 and rear 11 rollers and vertical axles four axes of roller 12 are mounted on a carriage on horizontal axes x 8 and 9. The horizontal axis 9 of the rear pair of rollers 11 is made with eccentricity e. An adjustable weight 13 is also installed on the carriage, allowing you to position the center of gravity; these mobile units of the grader (pos. 1-13) between the axes 8 and 9 1O and 11, near the axis 8. The rollers 10 and 11 of the carriage are installed in the C-shaped horizontal directions of 14, the groove height of which larger than the diameter of these rollers by the size of the gap in. The horizontal 14 and vertical 15 guides are fixed on the frame 16, on which the displacement cylinder 17 connected through the levers 18 with 1 meter 1 is pivotally mounted. The device works as follows: The pick-up is restored to its original position, the support rollers 5 and the cutters G are divorced t by means of cylinders 7 and 17 (they are retracted), the carriage 1 is retracted to the extreme right position, the rollers 12 touch the vertical guides, and because of the location of the center of gravity of the moving grader between the two pairs of rollers 10 and 11, they concern neither There are shelves of horizontal guides 14. The upper forming supporting roller 5 fixed on the lever 2 is installed above the lower surface of the strip 19 by the value a due to the rotation of the eccentric axis 9. After the end of welding, the working medium (air or oil) is fed into the piston cavity of the convergence cylinder 7 and the lever 4 is rotated around the axis 3, and the support rollers 5 and the cutters 6 are reduced. Then the working medium is fed into the piston cavity of the hydraulic cylinder 17, which, through the levers 18, drives the moving parts of the grater. The carriage 1 with the levers 2 and 4 is moved on the rollers 1O and 11, rolling along the lower shelf of the guide 14, and the rollers 12 hold the carriage in the guides 15. The support rollers 5 run over the strip 19 clamped in the welding jaws (FIG. 2 is not shown), and moved apart by the thickness of the &strip; and having the support roller 5 is lowered by the value of a. In this case, the carriage 1 with the levers 2 and 4 is turned around the point of contact of the front rollers 1O with the lower flange of the guide 14, and gaps O and Ol are formed between the rear rollers 11 and this guide. Now, the moving grader units are rolling on the support rollers 5 on the surface of the strip 19 and on the front rollers 10 - along the guide 14. Moving next to the support rollers 5, which copy the shape of the strip, the cutters 6 cut the burr. After the suture has been stripped off, the working medium is supplied to the cylinder cavities 7 and 17, the support rollers 5 and the cutters 6 are diluted and the carriage 1 with the levers 2 and 4 returns to its original position. Claims an incisor reamer for stripping the seam of butt-welded metal strips, containing a frame with guides and a movable part mounted on them with a carriage and two levers, one of the levers being connected to the carriage hinge, and the ends of the levers on one side are connected to drive them on the other hand, they are provided with support rollers and cutters, distinguished by the fact that, in order to increase the productivity and quality of the stripping, one of the levers is rigidly connected with the carriage equipped with two pairs of rollers installed with rum in the guide frame, the front rollers are located near the center of T tin of the movable part, and the rear rollers are installed. flax on an axis with eccentricity.
