How to make vane pump vane

Abstract

The invention discloses a method for manufacturing blades of a vane pump, which comprises the following steps: step 1, using a band saw to cut out basic blade blanks, and then blanking; step 2, milling both sides of the blade blanks by a milling machine; Step 3, flat grinding the blade blanks milled by the milling machine; Step 4, heat-treating the flat-ground blade blanks; Step 5, grinding the thickness and height of the heat-treated blade blanks, and then performing rough polishing Step 6: Grinding the side of the blade blank that is in contact with the pressurized cavity; Step 7: Grinding the height and width of the semi-finished blade, and then roughly throwing it; Step 8: Cleaning the finished blade after classification . The manufacturing method of the vane pump vane of the present invention can effectively realize the production of the vane through the setting of steps 1 to 8, and multiple parts of the vane are polished during the production process, which effectively improves the smoothness of the vane .

Description

Technical field[0001]The present invention relates to a method of fabricating a method, and more particularly to a method of fabricating a blade pump blade.Background technique[0002]The blade pump is a pressurized pump, which is commonly used in the prior art, can effectively realize the existing liquid or gas to perform a pressurization operation, so that the effect is achieved.[0003]The pressing principle of the blade pump is mainly by setting a press cavity, and a rotating shaft can be rotatable at the center position of the press cavity, and a plurality of blades can be shaped in the rotating shaft, during operation, The centrifugal force is generated by the rotation of the rotating shaft to cause the blade to be taken out, and then bonded to the cavity wall of the press cavity to ensure the effect of the sealing and pressurization, so the tablets of the pressurized cavity will contact friction, so the leaves It is easy to generate wear, and the smoothness of the blade is requir...

AI Technical Summary

Problems solved by technology

[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
