Horizontal Band Saw Layout With Fixed Cutting End Point
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional horizontal band saw machines require complex detection or calculation of the cutting end point due to variations in workpiece width and cross-sectional shape, leading to inefficiencies in cutting processes.
Innovation Solution
The horizontal band saw machine design includes a fixing vise jaw, a guide post, and a cutting head with a driving wheel and driven wheel configuration where the driving wheel's center is above the driven wheel's center, allowing the cutting end point to be uniquely defined by a shared reference plane, eliminating the need for detection or calculation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the band saw blade is tilted to form an upward inclination for cutting workpieces of varying width and shape, then the machine can accommodate different workpiece geometries, but the cutting end point changes with each cutting condition requiring complex detection or calculation
Solution Approach 1:
Instead of having the cutting blade tilt upward to accommodate workpiece variations, this patent inverts the approach by tilting the blade downward. The lower end of the blade is positioned closer to the fixed vise jaw than the upper end, creating a downward inclination that maintains a consistent cutting end point at the fixed vise jaw regardless of workpiece geometry, thereby eliminating the need for complex detection or calculation systems
Solution Approach 2:
The fixed vise jaw serves a dual function: it not only clamps the workpiece but also defines the cutting end point through its reference plane. This self-service approach allows the vise jaw to automatically determine the cutting termination position without requiring separate detection or calculation mechanisms, simplifying the overall system while maintaining adaptability to various workpiece dimensions
2Adaptability or versatility
If the cutting end point is allowed to change with cutting conditions to accommodate different workpiece dimensions, then all workpiece geometries can be processed, but the control system becomes complex requiring detection or calculation mechanisms
Solution Approach 1:
The fixed vise jaw is designed to perform multiple functions simultaneously: it clamps the workpiece securely and serves as the universal reference for the cutting end point across all cutting conditions. This multi-functionality ensures that regardless of workpiece dimensions or cutting parameters, the cutting process always terminates at the same reference plane, maintaining operational simplicity while achieving universal applicability
Solution Approach 2:
The patent changes the inclination parameter of the band saw blade from upward to downward, and positions the lower end closer to the fixed vise jaw. This parameter change ensures that the cutting end point remains constant at the fixed vise jaw reference plane across all cutting conditions, eliminating the need for dynamic adjustment or complex control mechanisms while maintaining adaptability to various workpiece dimensions

AI summary
A horizontal band saw machine includes a fixing vise jaw and a cutting head configured to cut a workpiece while descending along a guide post extending in a vertical direction. The cutting head includes a housing to which a driving wheel and a driven wheel are rotatably attached, and an endless band saw blade tightly stretched between the driving wheel and the driven wheel. When the workpiece a is cut with the band saw blade, a center of the driving wheel is located above a center of the driven wheel and the housing moves linearly up and down along the guide post. A fixing vise reference, which is a vertical plane on which the fixing vise jaw fixes the workpiece, shares a cutting end point at which the band saw blade ends cutting of the workpiece.
