Abstract
The present invention relates to a technique for machining the valve cover packing warehouse of the high-pressure valve used by the petroleum equipment, the invention is characterized in that a field roller is arranged on the lathe tailstock and the rolling is executed by pushing the surface of the rolling hole with a low speed, in this way the precision of the machining bore can get to Ra0.4mu m, the invention has the advantages of increasing the working efficiency by several times, simple technique, reducing the surface roughness of the packing warehouse of the valve cover and increasing the working accuracy and service performance of the accessory, reducing the conversion sequence number, effectively preventing the reduction of the working accuracy and shortening the process cycle.
Description
Technical field
The present invention relates to a kind of processing technology of valve cap packing bin of high pressure valve for petroleum equipment, belong to the Machining Technology field.
Background technology
The requirement on machining accuracy of valve cap packing bin of high pressure valve for petroleum equipment is higher, and roundness tolerance is not more than 0.015mm, and surface roughness Ra is not more than 0.8 μ m, and processing technology is at present: car-half finish turning-corase grind-correct grinding.This process workpiece is carried often in process, and the process-cycle is long, and in grinding process, owing to be stepped bore, is not through hole, therefore is difficult for back chipping.Simultaneously, material hardness is less demanding, and during grinding, the easy scab wheel of material causes ground effect poor, easily reduces machining accuracy, and in the process, needs to cause production efficiency low to the frequent place under repair of emery wheel, and the emery wheel loss is big.
Summary of the invention
The purpose of this invention is to provide a kind of reduction valve gap packing bin surface roughness, enhance productivity and the processing technology of the valve cap packing bin of high pressure valve for petroleum equipment of the machining accuracy of part and serviceability.
For realizing above purpose, technical scheme of the present invention provides a kind of processing technology of valve cap packing bin of high pressure valve for petroleum equipment, it is characterized in that, adopts rolling processing process, and its processing step is:
The first step on numerically controlled lathe, starts numerically controlled lathe with the valve gap clamping, and the packing bin of valve gap is carried out fine finishining, and boring is to the tolerance dimension of packing bin, and surface roughness should reach Ra1.6 μ m, blows clean iron filings in the storehouse with high pressure air rifle;
Second step. second step. stitching is installed on tail stock, stitching is transferred to than the big 0.015～0.03mm of accurately machined size;
The 3rd step. set 70-150 rev/min of lathe rotating speed, in the needle roller of stitching and packing bin, add machine oil, and setting amount of feeding 0.2-0.4mm/rev, the Push-type bed tailstock is pushed into the packing bin aperture with stitching, the locking tail stock rotates the tailstock handwheel stitching is clamp-oned packing bin, at the uniform velocity pushes the packing bin bottom, counter-rotating tailstock handwheel withdraws from stitching;
The 4th step. check measurement packing bin dimensional tolerance and surface roughness, dimensional tolerance are between 0～+ 0.07, and surface roughness is between Ra0.4～Ra0.8.
Described stitching is made up of taper shank, adjusting screw thread, adjusting shell, needle roller maintainance set and needle roller, and taper shank is connected with the needle roller maintainance set by regulating screw thread, regulates screw thread and is provided with the adjusting shell outward, and the termination of needle roller maintainance set is provided with needle roller.
The present invention adopts rolling processing process, carry out roll extrusion by advancing the hole rolling surface at a slow speed, can make the endoporus precision of processing reach Ra0.4 μ m like this, rolling and processing is an ELEMENTARY INTRODUCTION TO NON, acomia thermal phenomenon, finish size are compact dimensions, and processing dimension is controlled easily, rolling and processing parts list surface layer produces residual compressive stress and cold hardening simultaneously, can improve the fatigue strength of part.
Advantage of the present invention is to utilize rolling processing process processing valve gap packing bin, has reduced valve gap packing bin surface roughness, has improved the machining accuracy of part greatly and has guaranteed serviceability, and can enhance productivity exponentially.
