Embodiment Construction

[0056] figure 1 It is a schematic diagram showing how the burr 20 existing on the welding position of two blanks is cut. The device according to the invention comprises an idler disk which is free to rotate about its axis when an appropriate torque is applied.

[0057] Such as figure 2As can be seen, the disc is positioned such that the reaction force experienced by the cutting disc when it contacts the burr causes the disc to rotate. Thus, no rotary drive mechanism (eg, a motor) is required for cutting. The reaction force Fc has a horizontal component Fa and a vertical component Fb. The cutting disc torque is the product of the vertical component Fb of the reaction force and the radius of the cutting disc.

[0058] Also, considering that each cutting disc is idling and only rotates when it contacts a burr, or that is, each cutting disc rotates at a speed that is a result of the stock speed, there is no need to adjust the stock speed to the cutting speed . This makes th...

Abstract

Apparatus (25, 25') for removing burrs (22) on billets (20) characterized in that it comprises: - a supporting element (26, 26'), - at least two arms (28, 30, 28', 30') extending from said supporting element (26,26'), - deburring means (24, 34, 24', 34') able to be driven in rotation by burrs (22) of billets (20), the deburring means (24,34,24',34') being supported by the arms (28,30,28',30'), - driving means (35) for driving rotatably and reversibly the apparatus (25,25') between a stand-by position wherein the apparatus (25,25') is spaced apart from the billet (20) to be deburred and a working position wherein the deburring means (24,34,24',34') are close to the billet (20) to be deburred and are able to contact a burr (22).

Description

technical field [0001] The invention relates to a device for deburring during continuous rolling in which billets are joined together by welding. Background technique [0002] In modern rolling mills, billets are welded together to be subsequently rolled. When the blanks are welded to each other by flash butt welding, welding burrs are formed at the weld location by the flash and pressure exerted thereon. Since the welding burr is relatively large, it becomes a defect in the subsequent rolling process performed thereafter. During the rolling of the welded billet, there is even a possibility that the rolled product is damaged at the location of the defect. [0003] Therefore, the welding burrs must be completely removed before billet rolling. [0004] Document EP 1 057 563 discloses a method and an apparatus for deburring welded blanks, in which a cutting device located near the surface to be cleaned is translated towards the surface in order to intercept the burrs and per...
