Structural design of machining parts for busbar processing machine

First, the structure of the blank of the processing part of the bus processing machine

1. Reasonable design shape

2. Reduce the trim

3. Use nesting to cut

4. No welds should be placed at the section turning

5. Weldments can't ignore the characteristics of their own, simply imitate castings

6. Sectional shape should be beneficial to reduce deformation and stress concentration

7. Correct selection of weld location

8. Do not let the welding affected areas be too close together

9. Pay attention to the stress of the weld

10. The reinforcement rib arrangement of the weld should be reasonable

11. Reduce the stress of the weld

12. Reduce thermal deformation

13. Reasonable use of profiles to simplify the welding process

14. Welds should avoid machining surfaces

15. Consider gas diffusion

16. Can replace the workpiece with stamping parts

17. Use sheet bending to reduce welds


Second, the mechanical design of the structural design

1. Pay attention to reduce the blank size

2. The machined surface and the unmachined surface should not be flush

3. Reduce the length of the machined surface

4. Different processing precision surfaces should be separated

5. Change the shape of the complex parts into assemblies to facilitate processing

6. Avoid unnecessary precision requirements

7. The tool can easily enter or exit the processing surface

8. Avoid processing closed spaces

9. Avoid the tool can not approach the workpiece

10. It is not possible to adopt the shape of the part structure that is not suitable for the shape of the tool.

11. Take into account the impact of casting error

12. Avoid multiple parts processing

13. Complex machined surfaces should be designed on the outer surface rather than on the inner surface.

14. Avoid chamfering complex parts

15. Must avoid the mating of non-circular parts

16. Avoid unnecessary supplementary processing

17. Avoid part structures that cannot be clamped

18. Avoid part structure without measuring base

19. Avoid impact and vibration during processing

20. Avoid drilling holes on the slope

21. Do not create partial undrilled through the bottom of the through hole

22. Reduce the number of tools used to machine the same part

23. Avoid multiple fixes in processing

24. Note the possibility of having parts have multiple parts at a time


Third, heat treatment and surface treatment parts structural design

1. Avoid disparity in wall thickness of parts

2. Parts requiring high hardness (integral quenching treatment) size should not be too large

3. Avoid sharp corners and sudden size changes

4. Avoid using asymmetric structures

5. Avoid quenching open-shaped parts

6. Avoid the structure of the quenched parts is too complicated

7. Avoid the rigidity of the part is too low, resulting in quenching deformation

8. Use local quenching to reduce deformation

9. Avoid holes too close to the edge of the part

10. There should be a certain distance between the two gears of the high-frequency hardened gear block.

11. The surface of the galvanized steel parts should not be too rough

12. Electroplated mating parts should consider the thickness of the coating during machining

13. Note that plating parts are not suitable for certain working conditions.
