Abstract
A draw bench has a draw bed (1), with a die block (2) defining a draw axis (11), with a draw carriage (3) movable along the draw bed (1) and aligned with respect to the draw axis (11), and with at least two racks (5) arranged fixedly on the draw bed (1) and extending in the direction of the draw axis (11), which racks mesh with drivable drive gears (7, 8) provided in the draw carriage (3). The toothing (6) of the racks (5) are provided on sides of the racks (5) facing towards or away from each other, the line of action of the resulting tangential components (Ft) of the tooth forces (F) coincides with the draw axis (11) and the torques caused by the radial components (Fr) of the tooth forces (F) in the region of the two racks (5) and acting on the draw carriage (3) in opposite directions cancel each other out.
Claims8
A draw bench comprising:
- a draw bed with a die block defining a draw axis;
- a draw carriage movable along the draw bed and aligned with respect to the draw axis, and having at least two racks arranged in a fixed position on the draw bed and extending in a direction of the draw axis;
- wherein the racks mesh with drivable drive gears provided in the draw carriage;
- wherein the racks have toothing provided on sides of the racks that face towards or away from each other;
- wherein tooth forces are formed by the drive gears engaged with the toothing, and a line of action of tangential components of the tooth forces coincides with the draw axis;
- and
- wherein torques caused by radial components of the tooth forces in a region of the two racks and acting on the draw carriage in opposite directions cancel each other out.
