Patent number: 7334785Abstract: A locking vise for pipes, useful in operations for welding portions of plastic pipe by polywelding of the head portion. The vise comprises two mutually opposite jaws which form, when clamped, a circular locking seat for a portion of pipe. A slot is formed on the grip surface of each jaw in order to accommodate a corresponding portion of a body for reducing the diameter of the circular locking seat of the pipes. Elements for fixing to the corresponding jaw are further associated with each reduction body. The fixing elements comprise at least one locking pin, which can perform an axial translational motion and is inserted through the slot transversely to the slot. The locking pin has, in the axial direction, a first part, which forms, when arranged in the slot, an undercut for preventing extraction for the reduction body, and a second part, which is recessed with respect to the first part and forms, when arranged in the slot, a disengagement configuration for the reduction body.Type: GrantFiled: June 23, 2006Date of Patent: February 26, 2008Assignee: RITMO S.p.A.Inventor: Renzo Bortoli
