Cutting pipes with HavenTrak mobile shears

Haven Manufacturing, as a manufacturer of double blade shear technology, offers a family of products ideally suited to meet the above challenges. Haven’s unique double-blade cutters are designed to automatically and quickly cut round, square and irregularly shaped pipes and reach the appropriate lengths. Double-blade cutting is a series of two mechanically synchronized steps, referred to as “notching and shearing.” First, a horizontal “nick” blade cuts a flat groove in the top of the tube. Second, a vertical “shear” blade pierces this groove and cuts through the tube. Additional operations include a system to load the newly machined tubing and a feeder system that moves the tubing to the stop mechanism. Haven’s target mechanism uses a motorized pull screw to adjust the length of the parts being cut, allowing quick transition to a new production run requiring different cutting lengths. A clamping matrix, designed and manufactured for a specific pipe shape, secures the pipe to prevent damage and maintain tight length tolerances. A double-acting hydraulic cylinder provides the die clamping function, and an additional cylinder controls the stroke of the cutting motion. This unique system adjusts by applying low pressure for thin-walled pipes and then switching to high pressure for pipes with greater wall thickness. Since cutting double-blade shear pipe is a two-step process, a mechanical linkage keeps the horizontal blade away from the vertical blade. The horizontal cut removes some of the pipe’s outer material, preventing it from being deformed by the downward-directed force of the vertical cut. The vertical blade then splits the pipe, entering through a notch at the top and cutting through the pipe to the end. Haven’s dual blade system uses world-renowned control systems and is easy to set up and operate. A touchscreen display and intuitive menus allow commands to be executed and the controller to be easily configured.
