The flexible line deconstruction unit (54), comprises: - a flexible line section feeder (72) comprising an axial feeding and guiding system (92) having a flexible line section feeding axis (B-B'), the axial feeding and guiding system (92) being configured to receive a flexible line section (12) with the flexible line section longitudinal axis aligned with the feeding axis (B-B'), the flexible line section feeder (72) comprising a flexible line section driver (94, 96), configured to move the flexible line section (12) along the feeding axis (B-B'); and - an axial cutting tool (74), positioned in the axial feeding and guiding system (92) to cut an axial split (40) in the flexible line section (12) along the feeding axis (B-B').
摘要:
A method for industrial manufacture of pieces of wood (26) from tree trunks (2) which have at least been delimbed and wherein the manufacture as one part comprises feeding discs of wood (3) cut off from said trunks into a gap between a pair of rollers (15), (19) in order to form and detach pieces of wood (3) from said discs (3) by means of blade devices provided on a surface of both rollers (15), (19) in the pair of rollers for detaching pieces from the disc. The method comprises carrying out the cut-off sawing of the discs of wood (3) by means of one or more movable sawing devices (4) whose blade (25) is arranged to run in a transverse direction via ends of a plurality of adjacent tree trunks (2) located in a sawing station (1), at a distance from the ends which is a desired thickness for the disc and, subsequently, guiding the discs of wood (3) produced by sawing into the gap between said pair of rollers by means of a conveyor device.

There is provided in association with a wood working tool having a cutting blade (40), a carrier (10) which can receive wood and guide means (21) associated with the carrier to cause it to move past the blade on a predetermined path (13), whereby timer (14) carried by the carrier can be cut reproducibly to size. The carrier may have a groove or the like which corresponds to the shape to be cut which is received by the guide means and on movement of the carrier, the interaction between the groove and the guide means causes the carrier to follow the required path. The tool can have means whereby a number of similar articles can be cut from a single piece of material and the cutting of similar pieces can be effected automatically.
摘要:
A band saw blade sensor and control system to sense and control saw blade deviation of a continuous, flexible metal saw blade driven around a pair of pulleys. A pair of spaced proximity inductive sensors is positioned adjacent to a side of the saw blade in order to detect blade deviation during operation. A controller mechanism receives input from each of the pair of inductive sensors in order to control and adjust band tension on the blade, and in order to control and adjust blade force on a work piece.
摘要:
A band sawing machine for the axial cutting of metal tubes or bars comprising a support structure (1) provided with longitudinally aligned supports (6) for a piece (P) to be machined, and a gantry frame (9) mounted transversely thereon and holding a pair of coplanar motorized flywheels (14) with horizontal axes on which a continuous band cutting blade (15) is wound. The gantry frame is mounted slidingly on the support structure and motor means (30) are provided to transmit thereto a forward motion in a longitudinal direction, during which axial cutting of the piece is performed, and a motion of return to the starting position at the end of the operation.

The method consists of rotating the work piece, e.g. a bar or a tube, while feeding the cutter into engagement with the work piece. Cutter feeding continues at most to a depth equal to half of the diameter of the work piece. The machine consists of a T-shaped main body (1) has at its front end a cutting device (9). A work piece conveyor (4) is located at the back end of the main body (1). A rotary chuck (8) is placed between the cutting device (9) and the conveyor (4). The rotary chuck (8) consists of a DC motor (25) connected to a worm (26) and a worm wheel (27) secured to a carrier (28), which in turn secured to a carrier body (29) and a cover (30) by means of bearings, and there is hydraulically operated work piece clamping assembly (31-35) in said carrier (28).
摘要:
The present invention is directed to a horizontal band saw machine capable of efficiently severing H-beams without a trouble of saw blade's pinching in the kerf. In the horizontal band saw machine, a saw blade (21) can sever one of flanges 20a that has been cut first in an H-beam (20), completely from top to bottom, prior to approaching the center of a web 20b and its vicinity.
