Hydraulic jack process flow step by step diagram

The main components of the hydraulic jack are composed of cylinder block, piston rod, sealing ring, oil block, joint, etc., here is an introduction to the step-by-step diagram of the process flow mainly for the processing of cylinder block and piston. Through the selection and flaw detection of raw materials to the decomposition of the whole process of lathe processing, the components obtained are inspected and qualified, and the final assembled products meet the quality requirements. Only by persisting in every detail can the ideal product be produced in the end.

1. Material selection: Select the appropriate round bar from the raw material library, mainly referring to the steel grade and diameter.

2. Flaw detection: Use a flaw detector to detect the surface of the workpiece to ensure that the material meets the process requirements.

3. Blanking: cut a piece of material according to the size of the drawing.

4. Rough processing: the cut material is processed for the first time, the cylinder block is hollowed out, and the piston is processed to a predetermined diameter.

5. Brazing welding: brass wear layer is overlayed on the cylinder block and piston rod to extend the service life of the cylinder block piston.

6. Heat treatment: By changing the internal structure of the metal, the performance of the material is enhanced.

7. Finishing: Let the workpiece achieve high precision and surface quality.

8. Grinding: Through the grinding process, the workpiece is made further.

9. Fitter: process and drill the corresponding position of the workpiece according to the drawings.

10. Electroplating: hard nickel plating on the surface, enhancing the wear-resistant and corrosion resistance of the workpiece.

11. Polishing: Let the surface of the workpiece reach a higher level.

12. Testing: Before the workpiece is transferred to the next link, ensure that the workpiece meets the process requirements through testing.

13. Assembly: assemble each component, and conduct press tests, functional tests, etc.

14. Baking paint

15. Warehousing

Cairn strictly controls the quality, does a good job in products, and provides customers with high-quality hydraulic jacks.

For the knowledge points of hydraulic jack purchase, we explain in this article: "How to choose the right hydraulic jack".

In addition, we present youthe difference between hydraulic jacks of different models and specifications.
