Abstract
The invention relates to the technical field of engineering machinery, in particular to a bucket rod and a production method thereof. The bucket rod comprises a first connecting piece, a main pipe fitting and a second connecting piece which are sequentially connected, wherein the first connecting piece and the second connecting piece are made of metal; connecting ends are formed at the two ends of the main pipe fitting, and the main pipe fitting is made of a fiber reinforced composite material; and the portion, located between the two connecting ends, of the main pipe fitting is made of the fiber reinforced composite material. According to the bucket rod, the connecting ends are formed at the two ends of the main pipe fitting, the main pipe fitting is made of the fiber reinforced composite material, and the portion, located between the two connecting ends, of the main pipe fitting is made of the fiber reinforced composite material, so that the bucket rod is light in weight and high in strength, and the problem that the structural strength is inconsistent due to the fact that a bucket rod main body adopts a welding process is solved; and the first connecting piece and the second connecting piece which are connected with the main pipe fitting are made of metal materials, so that the wear resistance and the strength of the joint can be guaranteed, and the service life of the bucket rod is prolonged.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a stick and a production method for the stick. Background technique [0002] At present, the stick of the excavator is mostly welded by several plates, and its cross-section is usually rectangular, such as figure 1 As shown, stick 1 has the following disadvantages: [0003] 1. The stick is made of steel as a whole, with a heavy structure and no corrosion resistance, and it needs to consume a lot of hydraulic power during the working process; [0004] 2. During the manufacturing process of sticks, the welding process is used for welding. The consistency and quality of the welds are difficult to detect, and defects such as virtual welding and undercuts are prone to exist. Moreover, the smoke generated during the welding process is likely to pollute the environment and endanger health; [0005] 3. The designability of the structural strength is poor, and the cross-se...
