Embodiment Construction

[0032] The following is a specific embodiment of the present invention, and the present invention will be further described in conjunction with the accompanying drawings.

[0033] Such as Figure 1 to Figure 3 As shown, a processing method of locally reinforced all-fiber hydraulic cylinder barrel, one end of the cylinder barrel has a section of local strengthening area with thicker wall thickness, and the local strengthening area of ​​the cylinder barrel is formed by local upsetting;

[0034] The concrete processing steps of described cylinder barrel are:

[0035] 1. Material selection: choose straight cold-drawn tube as cylinder body 1, control cylinder wall thickness difference ≤ 10%, cylinder grain size ≥ 6 grades, no bad structures such as widmansite and banded crystals;

[0036] 2. Flaw detection: ultrasonic flaw detection;

[0037] 3. Cutting: reserve the total length of the blank according to the total deformation;

[0038] 4. Straightening: the straightness of t...

Abstract

The invention discloses a processing method of a local-reinforcement type full fiber cylinder barrel of a hydraulic cylinder, and relates to a local-reinforcement type full fiber cylinder barrel of a hydraulic cylinder. The processing method has the advantages that the use quality of the cylinder barrel of the hydraulic cylinder is improved, the design difficulty is decreased, the utilization rate of material is improved, and the processing cost and quality cost are reduced. The main material of the cylinder barrel is directly subject to local upsetting, the continuous distribution of metal fibers on the whole cylinder barrel is maintained, the local reinforcement of the cylinder barrel is realized, the stable transition and distribution of strength between the local reinforcement area and the cylinder barrel is realized, the load distribution of the cylinder barrel can be optimized, and the quality reliability of the cylinder barrel is favorably improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic cylinders, in particular to a processing method for locally strengthening full-fiber hydraulic cylinder barrels. Background technique [0002] The cylinder of the hydraulic cylinder is generally composed of two parts, the flange (or sheath) and the cylinder. In order to meet the strength requirements of the hydraulic cylinder, one end of the cylinder needs to be locally strengthened to thicken the wall. [0003] There are three types of traditional designs for hydraulic cylinder cylinders: the first design is integral forging, which requires high energy consumption and long cycle due to the need for overall heating and forging; the second design is assembly welding, due to uncontrollable welding quality factors In addition, the two base materials of welding materials and butt welding cannot be completely consistent, resulting in that the strength distribution requirements of the design requirem...
