Embodiment Construction

[0034] A water-jet cutting manufacturing method for an anti-chip board includes water-jet cutting pre-treatment, water-jet cutting process, water-jet cutting post-treatment and water-jet cutting quality process control method.

[0035] The method for manufacturing the chip-proof board by water jet cutting specifically includes the following steps:

[0036] Step 1. Re-inspection of raw materials and profiles: 100% inspection of the appearance quality and size of the cutting blank; cutting small samples on the cutting blank for re-inspection of its chemical composition; cutting standard tensile samples on the cutting blank, standard tensile test Age-hardening heat treatment is carried out after mechanical processing of the sample; tensile test, grain size determination and corrosion resistance test are carried out on the standard tensile sample after age hardening.

[0037] Step 2. Mechanical leveling of the cutting blank: Use mechanical methods to perform mechanical leveling on...

Abstract

The invention particularly relates to a water jet cutting manufacturing method for a chip prevention plate which comprises a water jet cutting pretreatment process, a water jet cutting process, a water jet cutting aftertreatment process and a water jet cutting quality process control method; in the water jet cutting process, a chip prevention plate water jet cutting clamp is used for clamping a to-be-cut workpiece; garnet is adopted as a water jet cutting abrasive material; and the cutting precision is controlled. According to the water jet cutting manufacturing method for the chip prevention plate, it can be guaranteed that after water jet cutting of the chip prevention plate is completed, the product size precision and surface quality meet product manufacturing requirements.

Description

technical field [0001] The invention relates to the technical field of manufacturing nuclear fuel components, in particular to a water jet cutting manufacturing method for a chip-proof plate. Background technique [0002] The anti-dust plate is located on the top of the lower nozzle of the nuclear fuel assembly, and is an important functional part of the core to filter debris in the primary circuit fluid and prevent nuclear fuel cladding from being eroded and damaged. The anti-chip board has a screen-like structure. Nearly 2,000 rectangular and round holes need to be processed on a thin plate with a thickness of about 3mm. The width of the ribs between the square holes must be controlled within the range of 0.5mm±0.1mm, which is difficult to process. The processing of existing products adopts the processing method of machining pre-hole + electric spark drilling. Since the dimensional accuracy of the hole manufactured by the EDM process depends on the machining accuracy of t...
