Problems solved by technology
[0002] The structure of the single-body pump is relatively complex and diverse, with both box-type characteristics and shaft-type characteristics. In actual processing, we cannot only consider a single processing method
The parts of the unit pump are box-shaped as a whole, but there is a shaft-type outer cylindrical surface on the outer wall. At present, the processing technology of the electronically controlled unit pump is poor, and the production cost is high. With the development of science and technology, the emission regulations are becoming more and more stringent. Strict and worldwide energy crisis, as well as the rapid development of electronic technology have promoted the pace of engine development towards numerical and intelligent

Embodiment Construction
[0052] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0053] The present invention aims at the existing problems, and an embodiment of the present invention provides a machining method for an electronically controlled unitary pump, which includes the following steps:
[0054] Step 1, blanking: process the 40CrMnMo raw material with a round steel cutting machine;
[0055] Step 2, forging blank: heat the raw material processed in step 1, then put it into a mold, use a punch to process it, use an electric screw press to process the mold segment, and finally perform edge trimming; the heating temperature is 950-1050°C.
[0056] Step 3, normalizing treatment: perform normalizing treatment on the blank after edge trimming; the normalizing temperature is 750±10°C, and the holding time is 180min; then cool to 650±...

Abstract
The invention provides a machining method of an electric control unit pump. The method comprises the steps of feeding, forging and pressing of a blank, normalizing, shot blasting, rough and finish turning of an outer circle, processing of a special-shaped profile, processing of an oil hole, marking, magnetic particle testing, inspection, and rust protection. According to the machining method of the electric control unit pump, the precision is high, the quality of monomer pumps is improved, the machining method is simple, the cost is low, and the production efficiency is improved, and the method can be used for producing and machining mass a large quantity of unit pumps.
Description
technical field [0001] The invention relates to the field of engine parts production, in particular to a machining method for an electronically controlled unit pump. Background technique [0002] The structure of the single pump is relatively complex and diverse, with both box-type characteristics and shaft-type characteristics. In actual processing, we cannot only consider a single processing method. The parts of the unit pump are box-shaped as a whole, but there is a shaft-type outer cylindrical surface on the outer wall. At present, the processing technology of the electronically controlled unit pump is poor, and the production cost is high. With the development of science and technology, the emission regulations are becoming more and more stringent. The severe and worldwide energy crisis, as well as the rapid development of electronic technology have promoted the pace of engine development towards numericalization and intelligence. In order to meet the development needs...
