Structural design of busbar processing machine to improve wear resistance, strength and stiffness

First, the structural design of the busbar processing machine to improve strength and rigidity

1. Avoid too far between the force point and the support point

2. Avoid cantilever structure or reduce cantilever length

3. Do not ignore the beneficial effects that the working load can produce.

4. Parts subject to vibration load avoid friction force transmission

5. Avoid imbalance in the organization

6. Avoid considering only a single route of transmission

7. The influence of part deformation on the force distribution during work should not be ignored.

8. Avoid high tensile stress on cast iron parts;

9. Avoid bending stress on thin rods

10. Impact load parts avoid excessive stiffness

11. Subjects with variable stresses to avoid rough or scratched surfaces

12. The surface of the stressed stress part should avoid residual tensile stress

13. Parts subject to variable load should avoid or reduce stress concentration

14. Avoid local structures that are too close to each other.

15. Avoid pre-deformation and the same direction of deformation caused by the workload

16. The diameter of the pulley and the reel of the wire rope should not be too small.

17. Avoid too many bending times of the wire rope, pay special attention to avoid repeated bending

18. When lifting, the wire rope and the reel must have a margin

19. Intermediate parts that can not transmit force should try to avoid stress

20. Try to avoid the additional force generated by the misalignment of the axis during installation.

21. Minimize the force acting on the foundation


Second, improve the wear resistance of the structural design

1. Avoid the same material as a sliding friction pair

2. Avoid the white alloy wear layer thickness is too large

3. Avoid increasing the requirements on the entire part in order to improve the wear resistance of the surface of the part.

4. Avoid partial wear of large parts and cause the entire part to be scrapped

5. When using white alloy as bearing lining, attention should be paid to the selection of bearing material and the structure design of bearing bush.

6. Lubricant supply is sufficient, full of working surface

7. The oil tank should not be too small

8. Do not filter the filter to remove additives from the lubricant.

9. The size, position and shape of the oil groove of the sliding bearing should be reasonable.

10. The amount of grease added to the rolling bearing should not be excessive

11. Add a certain amount of wear margin to the wearable surface of the part

12. Pay attention to the adjustment after the parts wear out

13. The speed and pressure difference between points on the same contact surface should be small

14. Use dustproof device to prevent abrasive wear

15. Avoid the formation of step wear

16. Sliding bearings cannot be used with contact oil seals

17. Protect the wearable parts

18. For wear-resistant parts, structures that automatically compensate for wear can be used.

19. Copper processing machine
