A thin-walled flow channel pressurized abrasive flow device

Abstract

The invention discloses a thin wall runner pressurized abrasive flow device which comprises a circulating pressure pump and an internal and external pressure balancer, wherein the internal and external pressure balancer comprises an inlet tube and an outlet tube; an outlet end of the circulating pressure pump is connected with the inlet tube of a partial pressure tube of the internal and externalpressure balancer; and an inlet end of the circulating pressure pump is connected with the outer side of an outlet tube of the internal and external pressure balancer. The thin wall pressurized abrasive flow device has the advantages of being simple in structure and comprises the circulating pressure pump and the internal and external pressure balancer; the internal and external pressure balancercomprises the inlet tube and the outlet tube; the outlet end of the circulating pressure pump is connected with the inlet tube of the partial pressure tube of the internal and external pressure balancer; and the inlet end of the circulating pressure pump is connected with the outer side of the outlet tube of the internal and external pressure balancer. With adoption of the internal and external pressure balancer, the internal pressure and the external pressure of a structure body is balanced in the process of processing a workpiece inner runner structure through abrasive flow, so that the abrasive flow pressurization is not limited by a thin wall of the workpiece, the abrasive flow grinding efficiency of the inner runner structure can be greatly improved and a processing reject ratio is reduced.

Description

technical field [0001] The invention relates to an abrasive flow device, in particular to a pressurized abrasive flow device with a thin-walled flow channel. Background technique [0002] Abrasive flow processing is to apply pressure on the liquid flow added with abrasive grains, so that the abrasive flow continuously grinds the surface of the workpiece, thereby completing deburring and polishing. For the inner runner, abrasive flow processing can be used to complete complex inner surface polishing that is difficult to achieve by mechanical grinding and other processes. [0003] With the emergence of technologies such as 3D printing, there are more and more thin-walled inner runner structures. The roughness of the inner surface of the 3D printed inner runner structure is relatively large, which has a great influence on the performance of the runner, so inner surface polishing measures must be adopted. In the usual abrasive flow processing, it is necessary to apply a large ...
