Manufacturing method for vanes of vane pump

Abstract

The invention discloses a manufacturing method for vanes of a vane pump. The manufacturing method comprises the following steps: step I, using a band sewing machine to cut out basic vane blank, and unloading the basic vane blank; step II, milling double side surfaces of the vane blank through a milling machine; step III, flatly grinding the vane blank milled by the milling machine; step IV, thermally treating the flatly grinded vane blank; step V, grinding the thickness and the height of the vane blank subjected to thermal treatment, and performing rough polishing on the vane blank; step VI, grinding one side, which is in contact with a pressurizing cavity, of the vane blank; step VII, grinding height and width of vane semi-finished products, and performing rough polishing on the vane semi-finished products; and step VIII, cleaning the sorted vane finished products. According to the manufacturing method for the vanes of the vane pump disclosed by the invention, the steps I to VIII areset, so that vanes can be effectively produced; and moreover, in the production process, multiple parts of the vanes are grinded by many times, so that smoothness of the vanes is effectively improved.

Description

technical field [0001] The invention relates to a manufacturing method, more specifically to a manufacturing method of vane pump blades. Background technique [0002] The vane pump is a kind of booster pump commonly used in the prior art. Through the action of the vane pump, a pressurization operation can be effectively realized for the existing liquid or gas, so as to achieve the effect of providing pressure. [0003] The pressurization principle of the vane pump is mainly to set a pressurized chamber, a rotating shaft can be rotatably set at the center of the pressurized chamber, and a plurality of vanes can be slidably arranged in the rotating shaft. During the working process, The centrifugal force generated by the rotation of the rotating shaft causes the blades to be thrown out, and then fit together with the wall of the pressurized chamber to ensure the effect of sealing and pressurizing, so the pressing sheet and the wall of the pressurized chamber will contact and r...

[0003] The pressurization principle of the vane pump is mainly to set a pressurized chamber, a rotating shaft can be rotatably set at the center of the pressurized chamber, and a plurality of vanes can be slidably arranged in the rotating shaft. During the working process, The centrifugal force generated by the rotation of the rotating shaft causes the blades to be thrown out, and then fit together with the wall of the pressurized chamber to ensure the effect of sealing and pressurizing, so the pressing sheet and the wall of the pressurized chamber will contact and rub, so the blades It is easy to wear and tear, and the blade needs to be smoothed. Therefore, the existing processing of the blade is mainly the way of cutting first and then grinding, that is, the blade is cut out, and then the corresponding grinding is carried out on the cutting position to make the blade become smoother. However, in the above-mentioned grinding process, only the roughness on the blade is polished, so that the smoothness of the finished blade is still slightly insufficient
