    摘要: The invention concerns a drive system (1) for a rolling mill, especially for a cold pilger rolling mill with at least one roll frame (1) movable back and forth, at least one crank drive (3) which has a crank arm (4) with a counterweight (5) for at least partial compensation of the inertial forces produced by the mill frame (2), a drive (6) and a connecting rod (7) which articulates the mill frame (2) and the crank arm (4) with one another and at least one counterweight (8, 9) which is eccentrically rotatable and serves to compensate the inertial forces and/or the moments of inertia. To achieve an efficient balancing of the inertial forces with a simple construction of the drive system, the invention provides that at least one counterweight (8, 9) is rotatably driven by a separate rod (10, 11) independently from the drive (6) of the crank drive.

    摘要: A process for rolling tubes, in which two grooved rolls mounted opposite one another in a roll stand are moved back and forth, i.e., reciprocated, on tube-shaped rolling material, which is arranged on a tapered rolling mandrel supported in the axial direction by a mandrel bar. The rotary-driven rolls have, on their circumferential surfaces, narrowing work grooves matching in shape to the tapered rolling mandrel, which roll down the rolling material on the rolling mandrel. At the ends of the work passes the rolls release the rolling material at the two dead centers of the roll stand path so as to assist in the advancement and rotation of the rolling material. According to the invention, the tube-shaped rolling material and the rolling mandrel are driven asynchronously in the same rotational direction at different rotational speeds.

    摘要: Disclosed are a method and apparatus for manufacturing tubes, preferably tubes composed of high-tensile steels or special alloys, using the cold pilger rolling method with two rolling stands which can be moved backward and forward, at least in opposite directions at times and in the rolling direction by means of crank drives. The rolling stands have rollers which are calibrated in a tapering manner and which, driven by toothed racks via cogs, roll over the material to be rolled, with an alternating rotation direction. The majority of the forming work takes place on the first rolling stand and a relatively small portion of the forming work takes place on the second rolling stand and additional smoothing work is carried out. Reduction rolling takes place in both rolling stands via a mandrel which is matched to the roller caliber, and the backward and forward movements of the two rolling stands are matched to one another in such a manner that the angular offset between the crank drives is chosen such that the forming zone of the first stand does not occur at the same time as the forming zone of the second stand.

    摘要: A forward feed gear mechanism for a cold pilger rolling mill having at least one forward feed slide, whose advancing movement can be derived from at least one forward feed spindle which is driven in continuous rotation, and an oscillating axial movement can be superimposed on the rotational movement of the forward feed spindle so that the gear mechanism is flexible and adaptable to different settings and provides high acceleration values with a simplified gear unit design. A planetary rolling spindle is provided for generating the axial movement of the forward feed spindles and is coaxially connected with one end of the forward feed spindle so as to be independently rotatable. The housing of the rolling spindle is rigidly arranged in the forward feed gear mechanism housing and the planetary rolling spindle can be driven in rotation in a translatory manner by a separate drive via a spur gear unit stage.

    摘要: A device for guiding away a cold-rolled tube from a cold pilger rolling mill that at least one of intermittently feeds and rotates the tube. The device including a constant-speed driver for drawing the tube from the rolling mill. The driver is arranged downstream of the rolling mill so that there is a buffer zone between the driver and the rolling mill. Additionally, an apparatus is arranged in the buffer zone for diverting the tube out of a roll direction by restrictively guiding the tube so that the tube describes a roughly S-shaped path in the buffer zone whereby cyclically non-uniform rolling speed of the rolling mill is compensated for.

    摘要: A method and apparatus for torque equalization on the drive of a rolling stand, having a linear oscillatory movement driven via a crank drive, of a Pilger step-by-step rolling mill, particularly a cold Pilger rolling mill. In order to avoid the inefficient and/or expensive drive and to create a torque equalization system which avoids generator operation of the motor of the drive device of the mill and therefore torques acting in the direction of rotation of the motor on the motor, the variation of speed of rotation of the crank drive, determined mathematically from the kinematic parameters of the system, the masses moved and the external loads, is imparted to the crank drive as a desired variation of speed of rotation.

    摘要: A drive for reciprocating a roll stand of a pilger cold-rolling system has a crank rotatable about an axis transverse to a reciprocation direction of the stand and a tie rod having an outer end journaled on the stand and an inner end eccentrically journaled on the crank so that rotation of the crank reciprocates the stand in the direction. A compensating weight is fixed to the crank opposite the tie rod and orbits in a weight plane on rotation of the crank. A counterweight is offset along the weight plane from the crank. A drive connects the counterweight to the crank for orbiting the counterweight in the weight plane on rotation of the crank.
