Problems solved by technology

[0003] 1. Using the welding process, the quality of the weld is unstable, and the structure of the heat-affected zone of the weld changes, often resulting in weld pores, incomplete fusion, etc., resulting in hydraulic steel pipe defects (such as oil leakage, hydraulic steel pipe fracture, etc.) ;
[0004] 2. A large number of welding processes are likely to cause pollution to the surrounding environment, especially CO 2 The emission of gas is incompatible with the purification of ambient air;
[0005] 3. Ultraviolet rays generated by welding arc light can cause damage to human eyes;
[0006] 4. The welding process requires a large number of pipe joints, welding wire, welding rods and other materials, and there is a waste of energy and labor due to repeated processing;
[0007] 5. During the cleaning process of hydraulic steel pipes, dirt often remains in the joints between steel pipes and joints, which affects the early wear of hydraulic components in the hydraulic system

Abstract

The invention discloses a hydraulic steel pipe connector and an extrusion forming method and a production device thereof. The hydraulic steel pipe connector extrusion forming method comprises the following steps that: step 1: preparing a steel pipe; step 2: high-frequency heating the connector end of the steel pipe so as to soften the connector end; step 3: extruding the connector end of the steel pipe to directly form a connector blank; step 4: mechanically processing the connector blank into a connector. The high-frequency heating direct-extruding formation is effectively combined with the working properties of the hydraulic steel pipe, so the hydraulic steel pipe connector has the advantages that: no weld seam exists, and the defects of the prior art can be avoided.

Description

technical field [0001] The invention relates to a hydraulic steel pipe joint, its extrusion molding method and its production equipment. Background technique [0002] All hydraulic steel pipe production methods at home and abroad so far adopt the following steps: Step 1, for processing steel pipes; Step 2, for processing joints; Step 3, for welding steel pipes and joints; Step 4, for machine Processing, welding of steel pipes and joints. This method mainly has the following major deficiencies: [0003] 1. Using the welding process, the quality of the weld is unstable, and the structure of the heat-affected zone of the weld changes, often resulting in weld pores, incomplete fusion, etc., resulting in hydraulic steel pipe defects (such as oil leakage, hydraulic steel pipe fracture, etc.) ; [0004] 2. A large number of welding processes are likely to cause pollution to the surrounding environment, especially CO 2 The emission of gas is incompatible with the purification of...
