Research On Complex Bore-Rolling Process For Cylinder Hole

As the enforce component for machine realize to-and-fro movement, It is most important to whole hydraulic system. By way of the mostly part, rolling cylinder-canister's hole is a more-faster new technique approximately, and apply abroad in the process of cylinder-canister. This paper based on the elasticity-mold basic theory,rolling principle,and deep hole machining technique ,research the elasticity-mold distortion, process design and the confirm of technique parameter in rolling cylinder-canister's hole process. Based on an project example, design the process of complex rolling bulldozer shovel cylinder, Study the force distortion of machining course and the in rolling, it also analysis the affect factor on quality control, discuss the affect on machining purpose of technique parameter in cylinder machining process. The paper consists of five chapters, given as follows: Chapter 1 Introduction Summarize the technique actuality of national and aboard in produce cylinder-canister, gives the main content obtained in this paper, and the realism purport to complex rolling explore in bulldozer shovel cylinder machining. Chapter 2 Elasticity-Mold distortion and rolling principle The chapter analyze the principle of elasticity-mold distortion in cylinder machining process, point out in rolling process, affect by the rolling force, the workface not only bring mold distortion but also produce elasticity distortion. by discuss on the rolling principle and affect factor in rolling ,knows the rolling value which decided the case of rolling force and the state of elasticity-mold distortion, so it decide the rolling mass. Chapter 3 Analyzing of cylinder-canister machining process As an example for the T140-1 bulldozer shovel cylinder canister, bases on the character and technique request, order the process for the cylinder, after in sew-tube roughcast, adopt the push-boring and forward discharge scraps finish gruff –boring and extractive-boring rolling be use for smooth machining. Discuss the adjust machine-tool work-piece, location and install rolling value and rolling quality etc. factor. Expatiate the frame truth of the complex rolling tools, and the route of the axis-force. Utilized the parse method, push on the result for count the rolling parameter. Finally, introduce the appliance of SIPM/CAPP craftwork design system in project the cylinder machine process. Chapter 4 Analyzing of cylinder-canister rolling process In the course of rolling, the boring pole and cylinder –canister's force make-up a relatively close system, the couple forces counteract each other, the boring pole mostly support axis force and torque. Analyzing the libation in cylinder rolling course, discuss the way for control or lower self-excitation vibration. Utilized the ANSYS PIPE16, BEAM4 and MASS21, confirm the vibration model of the boring pole in rolling, solve the first and second frequency. Chapter 5 Analyzing of the rolling quality and the prospect for new machining technique The chapter gives the main conclusion obtained in this paper and the prospect for next research. Gives the main affect factor on rolling quality, Refer to the national and aboard new technique in cylinder machining. Give the opinion of the rough-extrusion, apply inspect on line in rolling process.
