AI Technical Summary
Technical Problem
In existing band saw lifting components, ball screws have a shortened service life due to their heavy load capacity, resulting in high equipment maintenance costs.
Method used
A back pressure support assembly is installed between the saw frame and the base or stand to provide upward support force to share the load on the ball screw, and to improve stability and equipment compactness through multi-point support and optimized lever arm length.
Benefits of technology
This extends the service life of the ball screw, reduces equipment maintenance costs, and maintains the equipment's compact structure and stability.

Abstract
The utility model discloses a backpressure mechanism of a band sawing machine, which comprises a base, a vertical frame arranged on the base, a saw frame arranged on the vertical frame in a lifting and sliding manner, a lifting assembly for driving the saw frame to lift and a backpressure supporting assembly, the back pressure supporting assembly does not interfere with movement of the saw frame and always provides upward supporting force for the saw frame. Compared with the prior art, the back pressure supporting device has the advantages that upward supporting force is provided for the saw frame through the arranged back pressure supporting piece, the vertical gravity of the saw frame is further reduced, the stress on the ball screw is shared, the service life of the ball screw is further prolonged, and the later maintenance cost of equipment is reduced.
