Embodiment Construction

[0032] This part is the embodiment of the present invention, which is used to explain and illustrate the technical solution of the present invention.

[0033] A process method for improving the processing efficiency of jet sheet, comprising the following steps:

[0034] Step 1, preparing a jet sheet rough machining blank to obtain a round bar;

[0035] Step 2, the round bar is processed to the theoretical size by a centerless grinder, and cut into thin slices of 0.8-0.8mm by wire;

[0036] Step 3, processing the sheet on a surface grinder with a frozen suction cup platform, so that the flatness of the upper and lower surfaces of the sheet is within 0.002;

[0037] Step 4: Put several thin sheets into the jet sheet fixture by overlapping and combining them, and combine and process the special-shaped cavity and positioning pin hole of the jet sheet.

[0038] The threading hole of the jet sheet is processed before the heat treatment of the jet sheet rough blank.

Abstract

The invention belongs to the technical field of machining, and discloses a process method for improving the machining efficiency of a jet sheet, which comprises the following steps: preparing a rough machining blank of the jet sheet to obtain a round bar; the round bar is machined to the theoretical size through a centerless grinding machine, and the round bar is linearly cut into a sheet with the thickness of 0.8-0.8 mm; the slice is placed on a surface grinding machine with a freezing suction cup platform to be machined, and the planeness of the upper surface and the lower surface of the slice is within 0.002; a plurality of sheets are overlapped, combined and put into a jet sheet clamp, and the special-shaped cavity and the positioning pin hole of the jet sheet are machined in a combined mode. By the adoption of the method, 15-20 jet pieces can be machined at a time, the machining cost is greatly reduced, and the machining effect is improved; the problem that the low-speed wire feeding machine tool is not enough is solved; in addition, the method also guarantees the machining precision and consistency of the jet sheet.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a processing method of a jet sheet, in particular to a process method for improving the processing efficiency of a jet sheet. Background technique [0002] In the jet deflector valve, the jet sheet is a core component. The processing quality and efficiency of the jet determine the quality of the servo valve and the accuracy of product delivery. The current method of processing the jet sheet is single-piece processing. First, the jet sheet blank is processed and threaded Holes, followed by processing into I-shaped squares with slow wire walking, and finally processing the special-shaped cavity and positioning pin holes in the jet sheet with slow wire walking. The I-shaped square is processed by slow wire-feeding, and the single-chip processing takes nearly 4 hours. The processing efficiency is low, the labor cost is high, and the material consumption is large. It need...
