When cutting special materials, metal band saws will encounter problems such as slow work efficiency, low cutting accuracy, concave cutting surfaces, especially some thin-walled and large-diameter pipes or thin-walled profiles that need to be cut at a specific angle, and Some special parts (such as car engine connecting rods), etc., the most fundamental reason for these problems is that the workpiece has a special nature and is easily deformed during cutting, resulting in low cutting accuracy. With the continuous development of science and technology and the complicated design of component shapes and structures, it is also necessary to reform the traditional tooling and fixture forms. It can be seen that the design and manufacture of tooling fixtures for metal band saws are very important to the efficiency and accuracy of cutting.
So, what aspects should be paid attention to when designing fixtures?
1. Dimensions: the most important point, the size of the tooling must match the size of the workpiece (including basic dimensions and tolerances);
2. Structure: The main response is the positioning principle, which must be reasonably fixed on the workbench or jaws, and the workpiece can be fixed firmly;
3. Processing aspect: The designed tooling fixture should be as easy as possible to process, the production cycle is short, the production cost is as low as possible, and the cutting accuracy is high;
4. People-oriented: the designed fixture is more convenient to use and easy to operate.
