Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to a base frame in a band sawing machine,
More particularly, the present invention relates to a base frame that can be divided into a plurality of parts.

2. Description of the Related Art Conventionally, as a band saw machine, there is a rigid band saw machine in which a work table for supporting a work is provided so as to be reciprocally movable. The work table is configured to reciprocate by a dimension corresponding to the length of the work with the band saw blade at the center. Therefore, the length of the base frame that supports the work table needs to be at least twice the length of the work table, and is large.

(Problems to be Solved by the Invention) In the conventional configuration as described above, when the work becomes longer, the work table becomes longer and the base frame becomes extremely long. Therefore, when transporting the band sawing machine, in some cases, the base frame may be too large to transport.

[Structure of the Invention] (Means for Solving the Problems) In view of the above-described conventional problems, the present invention provides a work table supporting a work to be cut by a saw blade provided in a saw blade housing, by moving a work table in a lateral direction. In a base frame in a sawing machine that is supported so as to be able to reciprocate in the left-right direction on a base frame that has been extended, the base frame,

Positioning the work W and work table 5
After properly fixing the work table 5, the work table 5 is
By moving to the left in the drawing, the work W is cut by the band saw blade 25.

The structure of the connecting portion 7 between the main base frame 3A and one of the sub base frames 3B will be described in more detail. As shown in FIG. 4, the connecting portion 7 includes a main connecting portion 7U and a lower connecting portion 7L. 3A is connected to the sub base frames 3B and 3C.

More specifically, to connect the upper portions of the main base frame 3A and the sub base frame 3B, FIG.
As shown in FIG. 6, the guide rails 9A to 9A are formed at the center and both sides in the width direction at each connection end.
At positions close to 9D, joining blocks 35A, 35B, 35C and 37A, 37B, 37C machined so that the joining surfaces are in close contact with each other are integrally fixed by welding. Each of the joining blocks 35A to 35C and 37A to 37C is connected by a plurality of connecting bolts 39 in a state of being joined to each other.

As described above, when connecting the main base frame 3A and the sub base frame 3B with the connection bolts 39, in order to regulate the vertical direction so that the vertical displacement does not occur, each of the joining blocks 35A to 35C and 37A to 37C. Each of the machined upper surfaces is provided with a connecting block 41, and each connecting block 41 is fixed to each joining block 35 by a fixing bolt 43.
It is fixed to the upper surface of A to 35C and 37A to 37C.

Therefore, the upper surfaces of the joining blocks 35A to 35C and 37A to 37C coincide, and the vertical alignment is performed.

Also, main base frame 3A and sub base frame
In FIG. 5 and FIG. 6 in the front-rear direction with 3B, L-shaped fixing blocks 45 are integrally fixed to the joining blocks 35A and 35C on both sides so that there is no deviation in the left-right direction. A push bolt 47 for pressing and adjusting each of the joining blocks 37A and 37C in the front-rear direction is screwed. Therefore, by operating the push bolt 47, the main base frame 3A
, The sub base frame 3B can be adjusted back and forth, and alignment in the front and rear direction can be performed.

Therefore, when the main base frame 3A and the sub base frame 3B are connected, the guide rails 9A to 9D provided on the respective upper surfaces are aligned in a straight line.

To prevent cutting oil from leaking from the joint, a cover 49 is provided at the connection, and the main base frame 3A
A cutting oil recovery path 51 is formed between the cutting oil recovery passage 51 and the sub base frame 3B. More specifically, as shown in FIG. 4, a gutter holder 53 is attached to the opposing surfaces of the main base frame 3A and the sub base frame 3B so as to be inclined in the front-rear direction (the inclined state is not shown), Between the gutter holders 53, a gutter 55 whose upper part is opened is detachably supported.
The collection pipe 57 is connected to the lower end of the slope 55.

Therefore, leakage of cutting oil from the connection between the main base frame 3A and the sub base frame 3B can be prevented.

By the way, the lower connecting portion 7L includes a plurality of connecting bolts 59.
The connecting blocks 61A and 61B are joined together, and the longitudinal alignment is performed by a push bolt 65 screwed to an L-shaped identification block 63 fixed to one joining block 61A. The vertical adjustment bolt 67 is used to perform vertical alignment.

As can be understood from the above description, according to this embodiment, the base frame can be divided and conveyed, and when connected, front-rear, left-right, up-down alignment is easily performed with a simple configuration. be able to. In the case where the work table is exchanged according to the length of the work, the base frame can be made to have a length corresponding to the length of the work by connecting a sub-base frame of an appropriate size. . Further, leakage of cutting oil from the connecting portion is prevented, and contamination of the surroundings is prevented.

[Effects of the Invention] As can be understood from the above description of the embodiment, in short, the present invention provides a work table (5) supporting a work (W) cut by a saw blade provided in a saw blade housing (19). ), A base frame (3) extending in the left-right direction.
