Description

Band saw

The present invention relates to a band saw machine, especially a band saw machine that reduces the number of times the band saw is contacted and slows down the wear rate of the band saw.

Generally, due to space constraints, the wood must be cut into the desired size or shape by a band saw. Cutting first is also conducive to the convenience of subsequent processing. The structure of a common band saw machine consists of a band saw group (for cutting workpieces) and a platform group (for carrying workpieces). The platform group carries the displacement of the workpiece relative to the band saw group, so that the band saw group cuts the workpiece into desired size or shape.

Currently, in the structure disclosed in FIG. 2 according to US Patent Publication No. US10245660B2, the band saw is cut with saw teeth on one side, and the other side of the band saw has no saw teeth. When the wood moves forward with the platform group and is cut by the saw teeth on one side of the band saw, the wood will follow the platform group back to prepare for the next cutting, but in the process of going backward along the original path, the wood will have no saw teeth with the band saw. contact with the other side of the saw, or with the side of the saw, the wear and tear caused by long-term contact will cause the saw to break.

The axial displacement determines the path of the platform group in the Y axis. The offset mechanism is used to push the drive mechanism to rotate, thereby driving the platform group to re-displace in the X axis, resulting in the deviation of the Y axis path. moving, the workpiece moves away from the band saw group as the platform group is offset.

According to the second embodiment of the present invention, a band saw machine is provided, including: a band saw group; Axial displacement, the platform group includes a driving mechanism and an offset mechanism, the driving mechanism is used to control the displacement of the platform group in the X axis, and determine the path of the platform group in the Y axis, the offset mechanism It is used to push the drive mechanism to rotate, thereby driving the platform group to re-displace in the X-axis direction, causing the path of the Y-axis direction to deviate away from the band saw group.

In this way, not only the number of times the band saw is contacted, but also the speed at which the band saw is worn can be slowed down, thereby prolonging the service life of the band saw.

After the offset, the X-axis platform 50 will not follow the original Y-axis path, and the workpiece A will not be in contact with the other side or sideways of the band saw 23 without serrations during the return stroke.

To sum up, under the control of the band saw machine 10, when the platform group 30 is on the outgoing path: the workpiece A is cut for the first time with the platform group 30, and the workpiece A is in contact with the side of the band saw 23 with the saw teeth 231 and is Crop. When the platform set 30 is on the return path: the workpiece A is prepared for the next cutting with the platform set 30, the offset mechanism 70 will push the driving mechanism 60 to rotate, so that the platform set 30 is driven by the driving mechanism 60 to move to the X-axis again, thereby causing The path of the platform group 30 in the Y axis is offset, and the workpiece A moves away from the band saw group 20 with the offset of the platform group 30, so that the workpiece A does not contact the other side or sideways of the band saw 23 without serrations. In this way, not only the number of times the band saw 23 of the band saw group 20 is contacted, but also the speed at which the band saw 23 is worn can be slowed down, thereby prolonging the service life of the band saw 23 .
