Abstract
The invention relates to a method for processing and manufacturing an internal copper alloy. The method comprises the following steps: 1) forging the iron sleeve; 2) placing the iron sleeve into a mould, and pouring copper alloy; 3) and (5) cooling and forming, and then machining. The invention avoids the out-of-tolerance of the parallelism and the verticality of the product caused by the thermal deformation after cold assembly. The copper bush and the steel bush are prevented from moving, and the product quality is improved.
Description
Technical Field
The invention relates to a processing and manufacturing method for drilling a hole on the inner wall and embedding graphite after copper alloy is poured on the inner wall of a copper sleeve.
Background
Copper sheathing is gone into through the liquid nitrogen cold charge in original pressure rudder gyro wheel, adopts now directly to cast the copper alloy after the steel bushing inner wall, and inboard drilling, graphite inlay have solved former copper sheathing and steel bushing excircle concentricity problem, can solve traditional method of impressing simultaneously, and the copper sheathing can output and remove the problem.
Disclosure of Invention
The invention aims to overcome the defects and provides the internal copper alloy processing and manufacturing method which can improve the processing quality and realize the internal copper alloy processing quickly and efficiently.
The technical scheme adopted by the invention is as follows: the invention is carried out according to the following steps: 1) forging the iron sleeve; 2) placing the iron sleeve into a mould, and pouring copper alloy; 3) and (5) cooling and forming, and then machining.
And 2) in the step, a guide hole corresponding to the forming hole is formed in the upper surface of the die, and a guide pipe extends upwards from the guide hole.
The guide tube comprises an upper straight tube and a lower conical tube.
The outer surface of the guide pipe is provided with a support rod, and the upper surface of the die is provided with a support hole for the support rod to be inserted into.
The guide pipe is further structurally characterized in that the upper section of the guide pipe is a bell mouth, the lower section of the guide pipe is a broken straight pipe, and the lower section of the guide pipe is a conical pipe.
The invention has the advantages that: the invention casts the copper alloy in the steel sleeve, and omits the working procedure of liquid nitrogen cold charging. And the out-of-tolerance of the parallelism and the verticality of the product caused by the thermal deformation after cold assembly is avoided. The copper bush and the steel bush are prevented from moving, and the product quality is improved.

Detailed Description
The invention is carried out according to the following steps: 1) forging the iron sleeve; 2) placing the iron sleeve into a mould, and pouring copper alloy; 3) and (5) cooling and forming, and then machining.
And 2) in the step, a guide hole corresponding to the forming hole is formed in the upper surface of the die, and a guide pipe extends upwards from the guide hole.
The guide tube comprises an upper straight tube and a lower conical tube.
The outer surface of the guide pipe is provided with a support rod, and the upper surface of the die is provided with a support hole for the support rod to be inserted into.
The guide pipe is further structurally characterized in that the upper section of the guide pipe is a bell mouth, the lower section of the guide pipe is a broken straight pipe, and the lower section of the guide pipe is a conical pipe.
When the invention is used, the pouring liquid can smoothly enter the forming hole due to the arrangement of the guide pipe, and the guide pipe structure of the invention is arranged, so that the pouring liquid can smoothly enter the forming hole for casting and forming through the bell mouth of the upper section and finally through the transition of the straight pipe of the middle section and the guide of the conical pipe of the lower section.
The support rod is further arranged, so that the support rod can well and effectively support the guide pipe, the guide pipe is prevented from inclining in the pouring process, and the processing quality of copper alloy is ensured.
