Problems solved by technology

[0007] The purpose of the present invention is to solve the defects existing in the existing air grinding, abrasive flow polishing, and abrasive jet micro-polishing methods in the polishing process of parts, and to provide a water jet polishing process, which uses gas pressure to push the abrasive liquid to hit or slide over the workpiece Produces grinding effect, can deburr, chamfer and polish without causing damage to parts, low equipment cost, low operating cost, high efficiency, can be mass-produced, the abrasive will not cause surface hardening of the workpiece, and will not affect the subsequent adverse effects of processing

Embodiment 1

[0023] First use white corundum grinding liquid A to perform sandblasting and polishing on 36 Ф12 (diameter 12) fine punches arranged in a 6×6 manner at the same time through a water sandblasting machine, for chamfering and deburring, removing processing residues, and then using white Corundum abrasive liquid B was used to sandblast and polish the above 36 Ф12 fine blanks at the same time through a water blasting machine. The ratio of white corundum abrasive liquid A and white corundum abrasive liquid B and the process parameters of water blasting are shown in Table 1.

Embodiment 2

[0025] First, use white corundum abrasive liquid A to blast and polish 64 Ф18 fine blanks arranged in an 8×8 pattern at the same time through a water sandblasting machine for chamfering and deburring, and remove processing residues, and then use white corundum abrasive liquid B The above-mentioned 64 Ф18 fine blanks were sandblasted and polished by a water sandblasting machine at the same time. The ratio of white corundum abrasive liquid A and white corundum abrasive liquid B and the process parameters of water sandblasting are shown in Table 1.

Embodiment 3

[0027] First use white corundum abrasive liquid A to blast and polish 25 Ф14 fine blanks arranged in a 5×5 pattern at the same time through a water sandblasting machine for chamfering and deburring, and remove processing residues, and then use white corundum abrasive liquid B The above 25 Ф14 fine blanks were sandblasted and polished by a water sandblasting machine at the same time. The ratio of white corundum abrasive liquid A and white corundum abrasive liquid B and the process parameters of water sandblasting are shown in Table 1.

Abstract

The invention discloses a water jet polishing process, which aims to overcome the disadvantages in part polishing and processing of the conventional air grinding, abrasive flow polishing, and abrasive jet micro polishing methods. In the method, a plurality of fine blanking parts are simultaneously subjected to abrasive blasting and polishing by white corundum grinding fluid A and white corundum grinding fluid B sequentially and a liquid sandblast process. The white corundum grinding fluid A consists of 7.5 to 8.7 weight parts of water, 0.8 to 2 weight parts of white corundum and 0.3 to 0.7 weight part of anti-rust water; and the white corundum grinding fluid B consists of 6.3 to 8.5 weight parts of water, 1 to 3 weight parts of white corundum, 0.03 to 0.2 weight part of thickener, and 0.3to 0.7 weight part of anti-rust water. The process can be used for burring, chamfering, and polishing, the parts are not damaged and the equipment cost and operation cost is low, the efficiency is high, the process can be used for batch production, the workpiece surface is not hardened due to the abrasive, and adverse influence on subsequent processing and production is avoided.

Description

technical field [0001] The invention relates to the field of surface pretreatment of parts, in particular to a water jet polishing process for removing and polishing the surface of parts and improving the wear resistance of parts. Background technique [0002] At present, domestic and foreign parts polishing methods include air grinding, abrasive flow polishing, and abrasive jet fine polishing: [0003] 1. Air grinding: The principle is to use the gas pressure to push the abrasive balls containing abrasives to slide over or hit the workpiece to produce grinding effect. It can be deburred and chamfered and polished. The disadvantages are high equipment cost, high operating cost, low efficiency, and cannot be mass-produced ; [0004] 2. Abrasive flow polishing: the principle is to use pressure to push soft fluid containing abrasives through the workpiece to produce grinding effect, which can remove burrs and chamfer polishing, but the disadvantage is that the equipment cost i...
