Processing technology of precasting stainless steel high-pressure oil pipe inside automobile hybrid clutch shell

Abstract

The invention discloses a processing technology of precasting a stainless steel high-pressure oil pipe inside an automobile hybrid clutch shell. The processing technology comprises the steps that diecasting is carried out, particularly, a movable die insert mechanism is additionally arranged on a die to place the stainless steel high-pressure oil pipe, so that the stainless steel high-pressure oil pipe is precast in a product, and the die-casting action is decomposed: placing of the stainless steel high-pressure oil pipe the movable die through a mechanical hand, sliding block closing, die closing, filling pressure casting, die opening, sliding block opening, part taking by the mechanical hand, mist spray air blowing and repeated implementation of the steps; post processing is carried out, particularly, residue at a slag ladle nozzle is removed, and surface shot blasting treatment is carried out; machining is carried out: phi14.6 coating drilling roughing, phi12 milling cutter machining and hole roughing to phi15, and removal of stainless steel residual burrs by a phi14.8 ball cutter. The diameter of an original cutter is reduced, the number of milling cutters is increased to carry out layered milling, and hole burrs are removed through the ball cutter, so that the requirements for product performance and cleanliness are met.

Description

technical field [0001] The invention relates to a processing technology for pre-casting a stainless steel high-pressure oil pipe inside a hybrid casing of an automobile. Background technique [0002] The pre-cast stainless steel high-pressure oil pipe inside the car hybrid casing is an important channel for the car to run. The fuel supply of the oil pipe realizes the driving of the car. If the orifice is blocked, the normal oil supply of the oil circuit will be affected, and the burr residue in the orifice will affect the safety of the engine. Therefore, this invention has a vital impact on the normal driving and safety performance of automobiles. [0003] At present, in the actual production of automobile hybrid shells, it is found that the residual burrs of the internal pre-cast stainless steel high-pressure oil pipes cannot be removed during the machining process, which will affect the oil supply performance of the product, and the cleanliness cannot meet the requirements...

AI Technical Summary

Problems solved by technology

[0003] At present, in the actual production of automobile hybrid shells, it is found that the residual burrs of the internal pre-cast stainless steel high-pressure oil pipes cannot be removed during the machining process, which will affect the oil supply performance of the product, and the cleanliness cannot meet the requirements; moreover, stainless steel has good ductility, and the tools During processing, stainless steel will not be cut off directly like ordinary aluminum. Stainless steel encounters the reverse force of high-speed cutting of the tool, which will cause burrs to turn inside out and cannot be removed by processing.
