Description

Technical Field

[0001] The invention relates to the technical field of valve processing, and in particular to a hydraulic valve core processing device and a processing technology. Background Art

[0002] Metal hydraulic ball valves have the advantages of high strength and long life, and are widely used. The valve core of the metal hydraulic ball valve is spherical, with pin holes on the top and bottom, which are used to assemble with the upper handle and the lower sealing seat respectively, and then assembled with other valve accessories to manufacture a ball valve.

[0003] The existing Chinese patent with publication number CN117359323B discloses a ball valve core processing equipment, including an X-axis travel module, a Y-axis travel module and a processing spindle, which are assembled in an outer cover. The X-axis travel module is located at the bottom of the outer cover, and the Y-axis travel module is located above the X-axis travel module, and is equipped with a main clamp seat and a sub-clamp seat. The main clamp seat and the sub-clamp seat are used to clamp the valve core for processing. The processing spindle is located at the top of the outer cover, and is used to process the valve core clamped on the main clamp seat or the sub-clamp seat. In addition, it also includes a reversing assembly and a quenching assembly, which are respectively located on both sides of the processing spindle. The reversing assembly is used to fix and transfer the valve core to achieve the reversal of the valve core. The quenching assembly is used to quench the valve core on the main clamp seat.

[0004] The above-mentioned patent is mainly used for heat treatment of ball valves, but the current technology still has some shortcomings. For example, due to the special structure of the hydraulic ball valve core, it needs to be fixed with a clamp when drilling or turning holes. However, the current clamp is a multi-structure assembly structure or an outward expansion support structure, which is inconvenient to fix, and it is difficult to clean up the waste chips after the ball valve is processed.
