Abstract
ABSTRACT OF THE DISCLOSURE
The present invention relates to an improvement in a peeling machine having a hollow shaft carrying a cutter-head, the improvement being characterized in that the machine includes clamping means for feeding and removing a workpiece, said clamping means clamping each end of the workpiece, said clamping means moving through the hollow shaft and being adapted to move the workpiece axially of the cutter-head, said cutting means maintaining said work-piece in a clamped position during a complete peeling operation.

Description
The present inYention relates to peeling machines and more particularly, to an improYed clamping arrangement for peeling machines.
In order to make it possible to process short work-pieces in peeling machines, it has been proposed to arrange a collet on the rear clamping carriage, as seen in the direc-tion of travel of the workpieces, the collet being adapted to enter the hollow shaft, to clamp the front end of the work-piece already passing through the cutter-head, and to be drawn ;
completely through the said cutter-head. However, this -solution requires that the diameter of the hollow-shaft ;
bearings be substantialiy larger than would otherwise be :i necessary for peeling long workpieces. This inevitably results in a substantial increase in the price of the machine.
. :
Another disadvantage in such an arrangement is that short ; workpieces are not held at both ends throughout the peeling ;
1 operation.
~-According to a further proposal, in order to make it possible to peel short lengths of pipe on a pePling machine designed for long workpieces, and to avoid the disadvantage `~
of large hollow-shaft bearings, a pair of carriages are provided with clamping means in the form of mandrels pro-jecting into the pipe, the mandrels being tightened and ;
released by means of toggle-levers and pistons, in accordance with the movements of the clamping carriages. This proposal also requires two clamping-~arriages, with a~propriate clamping and control means for each carriage.
The present invention provides an improvement in an apparatus especially suitable for feeding and removing short workpieces to and from a peeling machine.

In one embodiment of the invention, there lS pro-vided in an apparatus including a peeling machine having a ..
stationary hollow shaft carrying a cutter-head, the machine being adapted for peeling short workpieces including those having a length smaller than the axial length of a hollow shaft and cutter-head, the improvement comprising: clamping means !;
-- constructed and arranged to axially move as a whole relative : .
to said cutter-head and including a single clamping carriage;
said clamping means further comprising first and second clamping elements adapted to securely clamp by frictional engagement axially opposed external ends of a workpiece exter-nally of the cutter-head and means for axially moving both of said clamping elements in unison and said clamped workpiece through the hollow shaft and said cutter-head while maintain-ing the workpiece in clamped condition during the entire !;',, , peeling operation.
According to the invention, the clamping means are :
designed and arranged in a manner such that the workpieces are already clamped and securely held by both clamping means before they enter the peeling machine, and remain so secured during the entire peeling operation. The clamping means are preferably in the form of a double-acting piston-cylinder drive and an abutment connected thereto by means of rails, the rails being connected together by cross-members running on wheels, and at least one of the said rails being pro-` vided with teeth engaging with a driven pinion. In order to make it possible for the piston rod to absorb the cutting ; torque, the double-acting piston has a second piston rod ':'' -

According to the invention, the clamping means are :
designed and arranged in a manner such that the workpieces are already clamped and securely held by both clamping means before they enter the peeling machine, and remain so secured during the entire peeling operation. The clamping means are preferably in the form of a double-acting piston-cylinder drive and an abutment connected thereto by means of rails, the rails being connected together by cross-members running on wheels, and at least one of the said rails being pro-` vided with teeth engaging with a driven pinion.

It lies within the scope of the invention also ~; to use a double-acting cylinder-piston drive instead ofthe fixed abutment arranged in one of the cross members.
^ This design and arrangement of clamping means makes ',s it possible to hold securely and peel short workpieces of any length and in the form of either rods or pipes. Discs and short pieces of rod may even be stacked and peeled.
~` 10 Only one "clamping carriage" is required, consisting of the cross members, connected together by the rails, for the ` accommodation of the means for clamping the workpieces, and this carriage may be moved back and forth by control means costing substantially less than conventional means. -~

~037Z44 The guide rollers, marked 5, support workpieces 6 in front ` of and behind the plane of the cutters. The peeling-machine ,. ~
housing is provided with sliding guides 7 for two rails 8, 8a bolted securely to cross members 9, 10, running on wheels.
Arranged in cross member 9 is a cylinder 12 containing a double-acting piston 13 equipped with two piston rods 13a, 13b. Rod 13a serves to clamp the workpieces, whereas rod 13b absorbs the cutting torque, to which end the said rod is equipped with fin-like radial projections 14 sliding in corresponding guides 15 is cross member 9. Attached to cross member 10, and secured against rotation in relation thereto, is a rod 16 which is arranged coaxially with piston rod 13a and serves as an abutment for the workpieces when they are clamped by . , .
piston rod 13a. Rail 8a has teeth 8b engaging with a pinion 18 secured to shaft 17. Shaft 17 is driven, through an -intermediate drive, by a control motor 20 (see Figure 2) adapted to rotate in either direction in order to move the "clamping carriage", consisting of cross members 9, 10 and rails 8, 8a, back and forth along tracks 21, 21a. Abutment ; 20 16 and piston rod 13a carry interchangeable clamping-pieces 22, 22a, which may be replaced by clamping pieces 23, illus-trated in Figure 4, when pipes are to be clamped. As may be seen in Figure 4, these clamping pieces are connected to piston rod 13a, and to abutment 16, by means of universal . , joints 24, so that workpieces which are not cut parallel may also be securedly clamped. Clamping pieces 23 are covered by a sliding sleeve 25 guided on clamping-piece ` holder 26 and loaded by means of a spring 27, so that, at the conclusion of the peeling operation, the pieces of the pipe are released from the said clamping pieces when piston rod 13a is retracted.

The sequence of events is as follows:
As may be seen in Figure 3, a workpiece support 30 is arranged in a pedestal 29 below the feed platform 28, support 30 being raised and lowered by motor 32 through shaft 31 in order to take workpiece 6 from platform 28 and place it in the position shown in Figures 1 and 3 for clamp-ing. As soon as support 30 has been moved, with the work- ;~
` piece, into the clamping position shown, a pressure medium is fed, through port 12a, to cylinder 12, so that piston 13 is caused to move to the left and clamping pieces 22, 22a ; come to rest against the end-faces of the workpiece and clamp -~
it. Motor 20 is then switched on, causing pinion 18 to ro-tate in the direction of arrow 40 and the "clamping carriage"
to move to the right, until the workpiece reaches the position indicated in dotted lines within the hollow shaft. Hollow ; shaft 2 is driven by control motor 33. At ~he conclusion of the peeling operation, pinion 18 is driven in the opposite direction of rotation, causing the "clamping carriage" to return to its starting position. A pressure medium is then fed to cylinder 12 through port 12b, causing piston 13, and clamping piece 22a, to move a short distance to the right, thus releasing the workpiece. Pressure medium fed at this time to cylinder 34 causes the piston therein to lower stop -35 until the workpiece on platform 28 rolls away to the right as soon as support 30 moves to the position indicated in dotted lines. Stop 35 is then raised again, whereas stop -36 is lowered by actuating the piston running in cylinder 37 ~
until the next workpiece 6a can roll onto support 30. Stop ~ -38 prevents the workpieces from continuing to roll when work-; 30 piece 6a rolls onto support 30. When stop 36 again assumes ~ -,~: :
