Abstract
A band saw having a generally vertically oriented saw blade carrying frame mounted to a movable carriage is disclosed. The carriage is mounted in a horizontally extending guideway in the saw base by an arm which is cantilevered from the back side of the vertical saw frame for support and guided motion of the saw from a relatively debris free portion of the saw base. Additionally, the band saw includes a work piece supporting bar feed table having a movable vise which is stabilized against backward tilting and a roller support assembly constructed so as to accommodate load concentrations from heavy, bent bar stock. Finally, an improved band saw blade guiding assembly is disclosed.
Claims5
A stabilization device for use in resisting backward tilting about a horizontal axis of a movable vise, said vise being formed for gripping of a work piece and mounted for reciprocation on viseways on a feed table to enable feeding of said work piece to a machine tool, such as a band saw, comprising:
- a stabilizing bar formed to be rigidly secured to said vise and formed to extend a substantial distance from said vise in a direction away from said machine tool, said stabilizing bar being further formed for engagement with and bearing upon a portion of said feed table remotely of said vise to provide a pivot point for tilting of said vise at a substantial distance away from said vise.
A feed table for use in feeding work pieces to a machine tool such as a band saw, said feed table including a frame having an upwardly facing work piece supporting surface, a vise movably mounted to said frame proximate said supporting surface for reciprocation toward and away from said machine tool to enable feeding of a work piece thereto, said vise being formed for selective gripping and release of said work piece, wherein the improvement in said feed table comprises:
- vise tilting stabilization means having a movable portion secured for movement with said vise means and a stationary portion mounted to said frame, said movable portion being formed as an elongated arm rigidly secured to said vise means and extending a substantial distance from said vise means in a direction away from said machine tool, said stationary portion being formed as a bearing surface extending along the direction of movement of said vise means over a portion of said frame on the side of said vise means away from said machine tool, and said movable portion further including bearing means positioned proximate the end of said arm remote of said vise means, said bearing means being formed for engagement with said bearing surface for all positions of said vise means.
