Embodiment Construction

[0034] A connection handle water jet cutting manufacturing method, including water jet cutting pre-treatment, water jet cutting and water jet cutting post-processing; the water jet cutting process uses the connection handle water jet cutting fixture to clamp the workpiece to be cut, using garnet as The water jet cuts the abrasive and controls the cutting accuracy.

[0035] The above method for manufacturing the connecting handle by waterjet cutting specifically includes the following steps: Step 1. Re-inspection of raw material profiles: 100% inspection of the appearance quality and size of the raw material profiles; cutting small samples on the raw material profiles for re-examination of its chemical composition; Cut the standard tensile sample on the raw material profile, and carry out the tensile test, grain size determination and corrosion resistance test after the standard tensile sample is machined.

[0036] Step 2. Shape of the rough-turned connection handle: Use CNC pr...

Abstract

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

Description

technical field [0001] The invention relates to the technical field of manufacturing nuclear fuel parts, in particular to a water jet cutting manufacturing method for a connecting handle. Background technique [0002] The connection handle is located at the top of the control rod assembly, and is one of the key core connection handle products for controlling the nuclear fission reaction power and starting and stopping the reactor. The structure of the connecting handle is to protrude 16 wings with different angles from a cylinder, and the thickness and position of the wings are highly required. The domestically produced pressurized water reactor control rod assembly adopts an overall processing and manufacturing scheme, which has the advantages of fewer parts and high structural strength, but it is relatively difficult to manufacture. The existing connecting handle product processing adopts the wire cutting method, but since the finished wing plate needs to be brazed later,...
