Abstract
The invention relates to a manufacturing method of an engine pressure shell, which comprises the following steps: designing the appearance of the engine shell, making marks in the place in need of bearing higher external force, carrying out sectional shell design on the part without need of bearing high external force, and performing casting and demolding treatment according to the mold design. The demolding agent for demolding treatment comprises 10-23g of sodium chloride, 2-8g of ethylene, 3-7g of sodium sulfate, 3-8g of glutamic acid and 25-45g of water. The part in need of bearing higher external force is prepared by the following steps: taking the casting raw material, carrying out ultrasonic vibration for 1-3 hours, and heating to 200-245 DEG C; repeatedly drawing to enhance the toughness; carrying out vacuum heat treatment in a bright quenching furnace; adding a catalyst propanol into a reaction kettle, reacting for 2-6 hours, taking out, cooling, and forming in the mold; and taking out, and splicing with the other parts. The engine pressure shell is specifically manufactured according to the stress conditions. The higher the specificity is, the better the effect is.
Description
technical field
the invention belongs to field of machining, particularly a kind of making method of engine pressure shell.
background technology
Engine is the power maincenter equipment of the various transportation equipments such as present carplane steamer, but the pressure be usually subject in the operational process of engine from other directions, therefore how the housing of motivity bears higher external force is exactly a kind of very important problem.
Summary of the invention
The invention provides a kind of making method of engine pressure shell, this making method can make the better motor body of sub-durability performance, protects and extend the work-ing life of engine.
A making method for engine pressure shell, comprises the following steps:
Use computer matlab software design to go out the profile of motor body, and need the place of bearing higher external force to make a mark.
Make mould, complete the preliminary sizing of mould according to the design of software.
Do not need the part of bearing how too high other places to carry out segmentation housing design, complete casting and demoulding process according to the design of mould.
The releasing agent that demoulding process uses comprises sodium-chlor 10-23g, ethene 2-8g, sodium sulfate 3-7g, L-glutamic acid 3-8g and water 25-45g.
Need to bear more part to complete in the following ways.
Get cast raw material, carry out vibration of ultrasonic wave 1-3 hour, heat 200-245 DEG C simultaneously.
Then drawing second repeatedly strengthens toughness, drawing number of times 2-5 time.
Bright quenching stove carries out vacuum heat treatment, quenching temperature 1000-1200 DEG C, and tempering temperature is selected in 800 DEG C, water-cooled after tempering.
Obtain material.
The material obtained, adds catalyzer propyl alcohol in reactor, and reaction 2-6 hour, after taking out, cooling, then puts into mould and carry out shaping.
Can splice with other parts after taking-up, obtain motor body.
Its advantage is:
Present method adopts the mode of staging treating to make motor body, can make targetedly according to the stressing conditions of different housings part, and the specific aim of making is better, better effects if.
