In the process of holding a non-toothed section of a band saw blade between a fixed insertion block and a movable insertion block included in a band saw blade guide device, the movable insertion block is moved while a return allowing unit included in an insertion block moving unit is held in a returnable state, the insertion block moving unit configured to move the movable insertion block toward the fixed insertion block. The band saw blade is firmly held between the fixed insertion block and the movable insertion block. Thereafter, the entirety of the insertion block moving unit, including the return allowing unit, is fixed in an immovable state by a mechanical fixing unit.

Disclosed is a main body vise device () in a band saw machine, characterized in that: a movable main body vise body () is provided to a main body vise bed (); an upstream movable vise jaw () is provided integrally to this main body vise body (), while a downstream movable vise jaw () is movably provided on a downstream side of the main body vise body (); a first pressing/biasing module () capable of advancing and retreating the main body vise body () is provided; and a second pressing/biasing module () capable of advancing and retreating the downstream movable vise jaw () independently of the upstream movable vise jaw () is provided.

Main body vise device in band saw machine

A workpiece cutting method utilizing a band-saw machine, includes the following steps of: guiding tooth tips of an endless band-saw blade provided on the band-saw machine in a direction of a workpiece by a band-saw blade guiding apparatus; and applying vibrations to the band-saw blade in a cutting direction to the workpiece so as to perform cutting of the workpiece by a vibration applying unit provided on the band-saw blade guiding apparatus.

Workpiece cutting method and band saw machine

A band saw machine includes a driving wheel and a driven wheel around which an endless band saw blade is wound. At least one of the driving wheel and the driven wheel is directly connected to an output shaft of a control motor. The output shaft of the control motor is arranged in a cylindrical bearing unit installed on a motor base supporting the control motor. The driving wheel is rotatably supported by the bearing unit.

Band saw machine

A method of cutting a workpiece using an endless band saw blade and a band saw machine are provided. The method includes suspending the endless band saw blade between a driving wheel and a driven wheel such that the workpiece may be cut by the endless band saw blade, applying at least a first pulse and a second pulse to a first motor rotating the driving wheel and a second motor rotating the driven wheel, respectively, wherein the pulses have phases opposite to each other, and cutting the workpiece. The band saw machine includes a driving wheel having a first motor and a driven wheel having a second motor. The band saw machine further includes a pulse applying module that applies at least a first pulse and a second pulse to the first motor and the second motor, respectively, wherein the pulses have phases opposite to each.

Method of cutting off workpiece using band saw machine as well as band saw machine

A bar storage apparatus comprises: a shelf frame (19) provided with a plurality of pallet accommodating shelves (17) each for movably accommodating a pallet (15) on which a plurality of bars are mounted; an elevator device (23) disposed on one side of the shelf frame so as to be movable up and down and provided with a traverser (21) for moving each pallet into and from each of the pallet accommodating shelves; and a bar supplying device (25) for supplying a bar, mounted on the pallet moved from the pallet accommodating shelf and further located at a predetermined position by the elevator device, to a bar processing machine (3). The bar storage apparatus can store a great number of bars of various kinds and various dimensions, select any required bars from a great number of bars, and supply the selected bars to a bar processing machine easily and quickly.

Bar storage apparatus

A transfer device for transferring elongate bars with respect to a spatial storing system which includes a shelf frame provided with vertically arranged multiple shelves constituted of a plurality of supporting beams for carrying the bars, comprising: a movable beam (23) disposed above the shelf frame and extending in a longitudinal direction of the bars, the movable beam being movable in a direction perpendicular to the longitudinal direction of the elongate bars; a lifting beam (35) vertically movably mounted on the movable beam; and a plurality of lifting arms (33) attached to the lifting beam and extending, for carrying the bars, in the direction perpendicular to the longitudinal direction of the bars, the lifting arms being extrudable and recedable separately or simultaneously in a longitudinal direction thereof in relation to length of the bar to be carried.

Device and method for transferring bars in spatial storing system

A bar transporting device for transporting bars into and out of a bar processing machine (63) which processes bars (B) of different shapes and dimensions. The bar transporting device (1) includes a shelf frame (7) provided with vertically arranged pallet shelves (5) onto which pallets (3) loaded with bars (B) are to be removably stored, a vertically movable elevating device (21) provided at one end of the shelf frame (7) and adapted to transport the pallets (3) into and out of the shelf frame (7) and transport the pallets (3) between the shelf frame (7) and a bar feeding position (71), and a bar forwarding device (77) for transporting the bars (B) between the pallet (3) removed from the shelf frame (7) and positioned at the bar feeding position (71) by the elevating device (21), and the bar processing machine (63).
