The invention relates to the technical field of pumps, in particular to a pump head body and a machining method of the pump head body. The pump head body comprises at least two spherical shell units, all the spherical shell units are sequentially connected, each spherical shell unit comprises a first hemispherical shell and a second hemispherical shell, the first hemispherical shells and the second hemispherical shells are connected to form the spherical shell units, and all the first hemispherical shells and the second hemispherical shells are of alternately-connected structures. The first hemispherical shells and the second hemispherical shells are mutually connected to form the spherical shell units, then the at least two spherical shell units are sequentially connected to form the pump head body, the pump head body is prevented from being formed through forging and pressing, compared with a pump head body formed through forging and pressing, the pump head body is smaller in internal tensile stress, quality inspection is relatively convenient, and the product quality is better guaranteed. In addition, the first hemispherical shells and the second hemispherical shells which are alternately connected can avoid intersection or overlapping between the connecting positions of the first hemispherical shells and the second hemispherical shells of the same spherical shell units and the connecting positions of the adjacent spherical shell units.
Description
technical field [0001] The invention relates to the technical field of pumps, in particular to a pump head body and a processing method for the pump head body. Background technique [0002] As a pressure-bearing component, the pump head body needs to bear alternating ultra-high pressure loads during operation. The existing pump head body is usually processed by forging and pressing, but it must be heated to a temperature above the plastic transformation point for die forging. Due to the high temperature and uneven heat dissipation, there will inevitably be internal tension stress and the forging effect of the core is relatively poor. Defects such as poor quality and difficult internal quality inspection lead to unstable product quality. Contents of the invention [0003] The problem solved by the invention is that the forging and pressing forming of the pump head body leads to unstable product quality. [0004] In order to solve the above problems, the present invention ...
