Abrasive flow polishing device for mold processing

Abstract

The invention provides an abrasive flow polishing device for mold processing. The device comprises an abrasive flow stirrer, a pressure pump, a pressure gauge, a main polishing tool, an auxiliary polishing tool and an abrasive flow recovery box, wherein the abrasive flow stirrer is sequentially connected with the pressure pump and the pressure gauge and then connected with the main polishing tool, and the auxiliary polishing tool specially used for machining pores and gaps of workpieces is connected to the main polishing tool. The main polishing tool is specially used for machining portions, such as protrusions, of molds, and the auxiliary polishing tool is arranged to be of a flexible thin structure so as to machine pores or gaps. A temperature sensor and a heater are arranged to reduce the influence of temperature and viscosity on abrasive flow machining precision and improve the polishing effect of surfaces of workpieces. The radial cross section shape of an abrasive flow jet orifice in the end of a rotary polishing head is designed to be in a quincunx shape, so that abrasive flow discharge volume and pressure value in unit time are increased, the superficial area of abrasive flow machining is increased, and the mold polishing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of high-precision polishing, in particular to an abrasive flow polishing device for mold processing, which belongs to the technical field of abrasive flow processing. Background technique [0002] Abrasive flow polishing technology has gradually become a very important high-precision processing technology. It uses the force of abrasive flow to remove a small amount of metal materials and polish the intersecting parts of the inner cavity of the part to achieve the purpose of fine processing. Abrasive flow machining has precision, stability and flexibility. [0003] At present, abrasive flow polishing technology has been widely used in the automobile industry and various manufacturing industries. Its most fundamental advantages are: it can access parts that are complex and difficult to access; the polished surface is uniform and complete; the processing effect of batch parts is repeated and consistent. These...

Problems solved by technology

[0005] In mold processing, abrasive flow polishing technology is also playing an increasingly important role. However, due to the complex curved surface or complex shape of some molds, they not only have many protrusions or shoulders, but also generally have some pores. Or grooves, although this structure can be processed in abrasive flow polishing, if a polishing tool is used to process protrusions and recesses such as shoulders, it will easily lead to low processing efficiency and high processing cost. To meet the needs of people, therefore, how to set up abrasive flow equipment that can take advantage of both the advantages of processing protrusions and the advantages of processing grooves is very important for mold processing
