Abstract

Disclosed is a main body vise device (7) in a band saw machine, characterized in that: a movable main body vise body (33) is provided to a main body vise bed (31); an upstream movable vise jaw (37) is provided integrally to this main body vise body (33), while a downstream movable vise jaw (41) is movably provided on a downstream side of the main body vise body (33); a first pressing/biasing module (43) capable of advancing and retreating the main body vise body (33) is provided; and a second pressing/biasing module (45) capable of advancing and retreating the downstream movable vise jaw (41) independently of the upstream movable vise jaw (37) is provided.

Claims

1. A main body vise device in a band saw machine, comprising:

a main body vise bed;

a main body vise body movably provided to the main body vise bed;

an upstream movable vise jaw integrally provided to the main body vise body, and opposed to an upstream fixed vise jaw;

a downstream movable vise jaw movably provided on a downstream side of the main body vise body, and opposed to a downstream fixed vise jaw;

a first pressing/biasing module configured to bias the main body vise body in a way that enables the main body vise body to advance and retreat; and

a second pressing/biasing module configured to bias the downstream movable vise jaw in a way that enables the downstream movable vise jaw to advance and retreat independently of the upstream movable vise jaw.

2. The main body vise device in a band saw machine according to claim 1, wherein a pressing force of the first pressing/biasing module is larger than a pressing force of the second pressing/biasing module.

3. The main body vise device in a band saw machine according to claim 1, wherein the first pressing/biasing module and the second pressing/biasing module each include a fluid pressure cylinder.

4. The main body vise device in a band saw machine according to claim 2, wherein the first pressing/biasing module and the second pressing/biasing module each include a fluid pressure cylinder.

5. The main body vise device in a band saw machine according to claim 4, wherein the second pressing/biasing module is a spring configured to always pressingly bias the downstream movable vise jaw toward the downstream fixed vise jaw.
