Definitions

  • Flame cutting with oxygen occurs on the two lower flame cut edges, i.e. separated at the beginning and end of each Workpiece through which and z. T. cooling cutting slag more or less large beards made of a mixture of brittle iron oxides and hard to elastic steel.
  • Partly these beards hang low from the edges like icicles, some are relatively flat Bumps on the edges of neighboring parts of the workpiece surface, some of them are arbitrary shaped and arbitrarily large compositions of the same. All are from the Material composition, the material temperature and the chemo-physical work values depending on the cutting devices. In any case, the presence of these beards is very disturbing Further processing, if not already during transport.
  • Avoiding such beards would be desirable, but cannot be achieved. A substantial reduction is possible depending on the circumstances, but not the size of the beard can be defined in advance and may therefore be permitted without rework.
  • thrust pinchers can also be used advantageously as hanging units, as claimed in claim 2 .
  • the slab (1) with its burnt beard (2) sits over the piston body (3) with its compressed air-operated deburring pistons (4) and their debarring chisels (5) driving push bars (6) Axle stub (7) of the piston body (3), whereby the action and reaction forces during debinding can cancel themselves close to their origin when the push bracket (6) drives the slab (1), driven by a motor, not shown, via a shaft (8) a gear (9) - both mounted in the frame (10) - and meshing with the toothed lower part of the thrust lever (11), pushes over the Entbartermeisel.
  • the push bar (6) can be extended by so-called push plates (12), the task of which is also the support bar (13), which is arranged close to the barker because of the shortness of the slabs (1), the push bar (6) extend. It is then possible to attack the slab (1) further up, in part above its end face, in order to prevent a short slab (1) from being lifted by a force component of the push bar (6) moving in a circle.
  • the push plates (12) have to be cut back obliquely and the adjacent support rollers (13) have to be designed as disc rollers into which the push plates (12) can protrude.
  • Figure 3 shows in situation a) the slab (1) with its first burnt beard (2) in the outlet direction above the debacher in the starting position, push bar (6) and piston body (3) with the debarker chisels (5) are at the angle ⁇ with the outlet direction plus ⁇ or ⁇ swung away. Due to the common drive push bar (6) and piston body (3) are pivoted to the left by the angle ⁇ , whereby the push bar (6) comes in front of the slab (1) by the angle ⁇ and the piston body (3) under the slab (1 ).
  • the push bracket (6) now runs together with the piston body (3) together in the second starting position d) for the first kiln (2), the beard chisel (5) is withdrawn. Then the slab (1) runs in the direction of discharge until its second kiln (2) has come into its deburring position according to situation e) in accordance with the starting position situation a). After the push bracket (6) and the piston body (3) have been turned to the left again in the starting position and the embrasure chisel (5) has been raised, the second burdle (2) can be removed as usual. After the complete debarking, the slab is now extracted.
  • the particularly favorable embodiment of the push drive de-sticking device shown in Figure 1 is registered as a further novelty on property rights.
  • the compressed air equipment required to extend the barber pistons (4) with barber (5) is also used to hold the piston body (3) in place.
  • the piston body (3) has two stub axles (7), which are mounted in an inner frame (10a), then support the stirrup levers (11) of the push bracket (6) and then with a multi-spline profile for slidably accommodating a cam disc ( 14) are provided with cams (15).
  • a piston (16) which, with a spring (18) supported on a spring bushing (17), via a nut (19) engages the cam disk (14) with its cams (15) in pushes the corresponding one of the bow levers (11) and holds them there so that they can rotate the piston body, which is also supported in the inner frame (10a) via the gearwheel (9) and shaft (8). If compressed air is added to the piston body (3) to extend the dislodged pistons (4), the piston (16) with its shoulder on the piston rod pushes the cam disc (14) with its cams (15) into the correspondingly drilled outer frame (10b) and holds the piston body (3) in this position, even if the push bar (6) continues to rotate.
  • an embarrassment chisel as shown in Figure 4 is claimed (5), which after its cutting (32) on its contact surfaces (31) alternately has an uneven length, but at least as long as the stinging beard (2) to be removed in the longitudinal direction of the slab (1 ) is reset.
  • These resets are called flutes (21) and expand into the barber's chisel by at least the angle ⁇ , which occurs when wedges are formed by twisting adjacent barber's chisels (5).
  • the flutes (20) should also be inclined in the vertical direction against the contact surfaces (31), so that once a piece of stinging beard (2) has penetrated, it not only does not become jammed, but also falls out when adjacent bearer chisels (5) are lifted and lowered as far as possible.
  • a thrust drive beater as described above which can reveal particularly short slabs (1) because support rollers (13) with disks are arranged in front of and behind it and the piston body (3) carries support rollers (21) with ball bearings on the side , which stand upwards in the starting and end positions of the piston body (3) and the short slabs (1) running over them butt at the tip. Otherwise, the support rollers (21) plunge into the gaps of the disks on the support rollers.
  • the claim 10 deals once again with the various situations a) to e) of the workflow in the exposed and the associated angular positions for controlling the locks and unlocks.
  • the following or approximate angular positions are particularly advantageous: Starting position Push handle (6) 90 grd Piston body (3) 60 grd. Starting position Push handle (6) 30 degrees Piston body (3) 0/360 degrees End revealed Push handle (6) 330 grd. Piston body (3) 0/360 degrees End position Push handle (6) 270 grd. Piston body (3) 300 grd.
  • a degrader in which the thrust drive consisting of cylinder (22), cylinder cover (23), the tie rods (24) holding them together and the invisible piston with piston rod (26), both a piston body - or this one as a unit with a cylinder cover (23) - with the debonding piston (4) and associated deburring chisel (5), as well as with rollers (25) in raceways (28).
  • the rollers (25) can be mounted in the cylinder covers (23).
  • the piston head (29) is articulated for best use of the available gap between the support rollers (13) below these support rollers (13) for the billet (1).
  • a debonder composed in this way can be lowered in raceways (28) bent downwards or those with lowering cylinders (30) outside the deburring process.
