How to improve the working strength of each component of the hydraulic wood grabber

As engineering project equipment,hydraulic wood grabberThe fatigue strength of components is related to the service life of the overall equipment and the acquisition speed of construction operations. The destruction of mechanical parts due to failure of production and processing is an important reason for the abnormal operation of industrial equipment. In the operation process of industrial equipment, mechanical parts According to the influence of several factors such as high temperature and high pressure, brittle cracking, damage, etc. occurs. Therefore, in the production process of mechanical parts, it is necessary to strictly supervise the quality of the mechanical parts themselves, especially the fatigue strength of the mechanical parts. In production, the performance of components must be improved according to technical means.

1. Minimizing the influence of the stress on the parts is the main measure to improve the fatigue strength of the parts. The sudden change of the structural shape and specifications of the parts is the root cause of the stress structure. Therefore, in order to reduce the stress better, try to avoid zero. The sudden change in the structural shape and specification of the component or the change should be made as smooth and uniform as possible. Therefore, the arc radius of the joint should be enlarged as much as possible; the stiffness change of the adjacent cross-section on the same component should be as small as possible.

Hydraulic wood grabbers can use unloading grooves to reduce the effect of stress in the structure where relatively large stress is inevitably formed.

2. The material with high fatigue strength and the heat treatment process and strengthening process that can improve the fatigue strength of the material are specified.

3. Improve the process performance of parts. For example, make the surface of parts in areas with high stress smoother; provide appropriate surface protection for parts that operate in corrosive substances.

4. Minimize or remove the original cracks that may occur on the surface of the parts, which has a more obvious effect on increasing the fatigue life of the parts than improving the material performance. Therefore, for the important parts of the hydraulic wood grabber, it should be specified on the design drawing. Strict testing methods and requirements.
