The following are specific examples of the present utility model.

Example 1

The main body portion of the vertical band sawing machine of this embodiment is substantially the same as the above-described structure.

The upper surface of the bed body 1 of the embodiment is provided with a stepping workbench 5 capable of transversely and reciprocally moving along the bed body 1. Specifically, a guide rail can be arranged in the bed body 1, the stepping workbench 5 is connected with the guide rail in a matched manner, and the stepping workbench is driven by a stepping motor to move along the guide rail. The rack can also be arranged in the bed body 1, the stepping workbench 5 is sleeved on the rack through a gear, and the gear is driven by a stepping motor, so that the stepping workbench 5 is driven to move. The connecting structure is an existing conventional structure in the mechanical field and is also a common structure of a movable workbench of an existing vertical band sawing machine.

The upper surface of the stepping workbench 5 is provided with a groove for limiting the cylindrical bar to be processed, a support 6 is fixedly arranged on the inner side or the outer side of the stepping workbench 5, and a compression cylinder 7 for clamping and fixing the bar to be processed is fixedly arranged on the support 6.

The bed body 1 of this embodiment is located at one side of the starting point of the stepping workbench 5, and is fixedly provided with a feeding mechanism 8. The feeding mechanism 8 comprises a base 81, a material table 82 with an inclined top surface is fixedly arranged at the top of the base 81, and the height of the lowest side of the material table 82 is flush with the height of the top surface of the stepping workbench 5. A gap is arranged between the material table 82 and the bed body 1, and the width of the gap is smaller than the diameter of the cylindrical bar to be processed.

The vertical band sawing machine of this embodiment further includes a jacking cylinder 84 for jacking the cylindrical bar to be processed, and the jacking cylinder 84 is fixedly disposed in the gap between the material table 82 and the bed body 1.
