摘要: A hydraulic actuating system for a hydraulically operated bending machine which is so designed and constructed that, by using an automatically operable pressure-sensitive valve, the hydraulic ram and driving apron is caused to move at an increased speed during its idle movement towards the workpiece by bypassing fluid from the discharge chamber of the ram to the drive chamber and at a decreased speed but increased force during the bending operation by passing fluid from the discharge chamber to the tank.

摘要: Contour machine in which a worktable is fixed, and enclosed wheels are provided for mounting a band saw, the machine being pivotable with respect to a base, and in which a rotary table, mounted on the worktable, may be automatically set into rotation in the forward or reverse direction or stopped through a curvesensing guide mechanism. The machine body is pivotable with respect to the base in a plane perpendicular to the face of the band saw, together with upper and lower housings which lodge wheels for guiding the band saw. The machine has means to provide an adjustable and reproducible relationship of the body with respect to the base, as well as means for immobilizing the pivoted machine body in various positions. In addition, with a view to attaining savings in manpower and automation of operation, units are provided for indication of the saw tension, for bringing a saw-container housing to a saw-mounting position, for clamping the saw, for adjusting the relative distance between a workpiece and a saw-blade guide mechanism, and a unit for stopping the saw movement upon completion of the machining operation.

摘要: A band saw blade includes: a body portion having a band-like and an endless shape; a tooth portion in which a tooth group, which is a set of a predetermined number of teeth including a set tooth, is repeatedly formed on one edge side of the body portion; and a coat layer which is formed on a surface of the teeth of the tooth portion. The set tooth has a first indentation portion as a recessed portion in the coat layer on an outer surface in a set direction, and thickness of the coat layer in the recessed portion of the first indentation portion is thinner than that of the coat layer in portions other than the recessed portion.
