Description

Technical Field

[0001] This invention relates to the field of steel pipe processing equipment technology, specifically to a steel pipe end extrusion forming equipment. Background Technology

[0002] In steel pipe manufacturing, the pipe ends often require plastic forming. Current technology commonly uses hydraulic equipment to drive molds for extrusion forming of the pipe ends.

[0003] In the prior art, patent document CN102240765A discloses a seamless steel pipe double-end flange forming machine. This machine mainly consists of a die-cutting main unit, clamping cylinder, forming mold, synchronous plate, synchronous tie rod, forming pressure head, and feeding robot. Its key feature is the integration of casting, forging, and welding technologies. Through the organic combination of mechanics, hydraulics, and electricity, the seamless pipe double-end flange forming machine achieves synchronous, equal pressure, and bidirectional forming. It adopts a horizontal four-tie rod translational motion, a perfect combination of constant speed and constant pressure mechanics and hydraulic systems, solving the defects of current hydraulic systems that cannot achieve constant speed and constant pressure movement and are prone to mechanical instability. This improves production efficiency, reduces worker labor intensity, lowers production costs, saves raw material consumption, and reduces CO2 emissions, making it a low-energy, pollution-free process equipment.

[0004] However, the above-mentioned technical solutions have poor clamping effect on steel pipes, and the clamping position is prone to deviation. During the extrusion process, the steel pipe is prone to loosening and shaking, resulting in low end extrusion forming accuracy and problems such as deformation and dimensional deviation. Furthermore, the extrusion accuracy is insufficient, and the extrusion force and extrusion position are difficult to control precisely, which cannot meet the forming requirements of steel pipe ends of different specifications. Moreover, the position adjustment is inconvenient, and the overall equipment and core components have poor position adjustment flexibility, making it difficult to adapt to the processing of steel pipes of different lengths and specifications, resulting in weak versatility. Fourthly, there is a lack of auxiliary positioning and an effective auxiliary clamping and adjustment structure, which makes the steel pipe end prone to deviation during the extrusion process, further affecting the forming accuracy. Based on this, the present invention provides a steel pipe end extrusion forming equipment to solve the problems mentioned in the background art. Summary of the Invention
