Abstract

A compound roll includes a sintered inner core of a first cemented carbide and at least one sintered outer sleeve of a second cemented carbide disposed around the inner core. The outer sleeve and inner core each have a joining surface, wherein when the inner core and outer sleeve are assembled each joining surface contact to form a bonding interface therebetween. When the assembled, sintered inner core and outer sleeve are heated to a predetermined temperature the sintered inner core and outer sleeve are fused together at the bonding interface to form the unitary compound roll. To reduce the overall cost of the compound roll, a lower cost cemented carbide, or a cemented carbide with a lower density can be used for the inner core and fused to an outer sleeve of a virgin cemented carbide, thereby reducing the powder cost and/or reducing the overall mass of the compound roll.

Abstract

The present invention relates to a cemented carbide tool for the deep drawing operations, especially as the ironing dies, of the manufacturing of aluminum or steel beverage cans. The cemented carbide comprises WC with an ultra fine grain size, a binder phase of Co, and grain growth inhibitors (V and/or Cr), wherein the Co content is from about 5 to about 10 wt-%, and with a specific relation between HV30 and cobalt content.

Abstract

A rotary cutting apparatus includes a cutter drum having at least one cutting member and an anvil drum having a rotary axis, arranged in a cutting relationship to one another, and a pressure actuating device for subjecting pressure on said cutting member in relation to the anvil drum. The pressure actuating device includes a pair of levers rotatable about at least one hinge having a horizontal axis. The horizontal axis is parallel to but non-concentric with the rotary axis. In addition, a frame supports the cutter drum and the anvil drum in a rotatable relationship. The pair of levers are releasably connected to the bearing housing, respectively, in such a way that the anvil drum is allowed to be removed from the frame.

Abstract

A rotatable anvil for a rotary cutting unit, including an axle, at least one anvil portion adapted to co-operate with a knife member of a rotary cutter, a pair of load transmitting portions adapted to abut a pair of abutment members of the rotary cutter, the pair of load transmitting portions being arranged on each side of the anvil portion, and deflection means provided underneath at least one of the anvil portion and the load transmitting portions. The invention also relates to a rotary cutting unit including a rotary cutting drum and a rotatable anvil.

Abstract

A rotary cutting unit includes a rotary cutter overlying a rotatable anvil. The anvil includes an axle, at least one anvil portion adapted to co-operate with a knife member of a rotary cutter, and a pair of load transmitting portions adapted to abut a pair of abutment members of the rotary cutter. The pair of load transmitting portions are arranged on each side of the anvil portion. A load receiving member is provided between each load transmitting portion and the anvil portion. Each of the load receiving members is connected to the axle via a bearing. Fluid cylinders apply upward forces to the load receiving members, wherein the total upward force exceeds the weight of the anvil.
