Abstract
The invention provides a method for processing an elastic ring of a Kaldo furnace, and aims to provide a method for processing the elastic ring of the Kaldo furnace with high strength, good elasticity and convenient processing method. The method is realized by a method of performing ring rolling on a blank of an elastic ring, and performing finish machining after rolling fulfills the size requirement.
Description
Technical field
The invention belongs to machining parts, be specifically related to a kind of processing method of many stoves of Ka Er elastic ring.
Background technology
Ka Er is many, and furnace apparatus comprises cylindrical furnace; This body of heater can be done rotation, fascinate; And a backing ring is installed, this backing ring is installed on the outside of shaft so that can produce above-mentioned motion, keeps certain interval between backing ring and the body of heater and is connected on the body of heater through elastic ring.The effect of elastic ring is to prevent that the body of heater motion that thermal expansion causes is delivered on the backing ring, and bears from the own wt of body of heater and the external loading of charging weight.Elastic ring is made up of the ring beam support ring of sealing; This ring beam support ring is connected with backing ring with body of heater respectively round shaft and through flexible connecting member, and the feasible thermal expansion campaign owing to body of heater of this flexible connecting member makes the angle between ring beam support ring and the body of heater do limited variation.These motions have been eliminated under the remarkable bending that the ring beam support ring has no in the real work situation or the situation of other distortion.
On import equipment, be furnished with many stoves of Ka Er elastic ring, but the many stoves of homemade Ka Er do not have this workpiece, do not have relevant processing method yet.
Summary of the invention
The processing method that the purpose of this invention is to provide easy many stoves of the Ka Er elastic ring of a kind of method.High, the good springiness of the elastic ring intensity that adopts this method to produce.
The present invention adopts following technical proposals to be achieved: the elastic ring blank is ground ring processing, grind and carry out fine finishining again after expansion reaches dimensional requirement.
Grinding ring is that ring-shaped work pieces grinds the abbreviation that expands, and is the new method that ring-shaped work pieces is shaped.Its operation principle is following, and the rolling wheel active rotation drives annular base rotation, and annular base drives the rotation of core roller again; Centre distance between rolling wheel and core roller is dwindled gradually simultaneously, and promptly the thickness of annular base reduces gradually, and diameter enlarges gradually, up to forming needed cross sectional shape; Guide roller works to induce the workpiece lopping and increases the stone roller expansion stable, and when workpiece contacted with the signal roller, expression had reached preliminary dimension, and the signal roller sends the smart signal that grinds and stop grinding, and the rolling wheel completion task of rolling returns to the home position.
Grinding ring technology has at home and abroad obtained using quite widely.The typical part that grinds ring technology has: outer race, gear ring, train wheel rim, lining, flange, bridge crane Wheel etc. in the bearing.The annular element size range is: diameter 40～10000mm, high 20～4000mm.The part maximum weight reaches 6000kg. adopts technique scheme, the material selection 50Mn2 of elastic ring; Grinding the ring processing technology adopts heat to grind.
Many stoves of Ka Er elastic ring should have high intensity, elasticity by its role.And the 50Mn2 structural alloy steel is the modified manganese steel of carbon in a kind of high strength, and it has high intensity, elasticity and wearability.The material of many stoves of Ka Er elastic ring is selected the 50Mn2 structural alloy steel for use among the present invention for this reason.
The temperature of grinding ring technology has three kinds: heat is ground, temperature is ground and cold roll.The small deformation that cold roll only limits to smallclothes grinds ring, but ratio of precision is higher; It is the widest that heat is ground the ring application, and the particularly shaping of large-sized annular spare is generally used as base; It is the technology between cold roll and heat are ground that temperature is ground ring, and its part precision is higher than heat grinds, and is mainly used on the higher part of middle-size and small-size precision.For this reason, the present invention grinds ring technology and selects for use heat to grind.
In sum, the invention has the beneficial effects as follows: the elastic ring blank is ground ring processing, grind and carry out fine finishining again after expansion reaches dimensional requirement, adopt this method technology simple; Because the elastic ring material is selected the 50Mn2 structural alloy steel for use, make the elastic ring of producing have the performance of high strength, good springiness.
Description of drawings
Fig. 1 is the sketch map of many stoves of Ka Er elastic ring.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
Selecting the processing external diameter in the present embodiment for use is 2860mm; Internal diameter 2720mm; Highly be many stoves of Ka Er elastic ring of 650mm, select for use material to do blank for the 50Mn2 structural alloy steel, after the blank of many stoves of Ka Er elastic ring is ground ring processing earlier: i.e. rolling wheel active rotation; Drive the rotation of annular resilient collar blank, the annular resilient collar blank drives the rotation of core roller again; Centre distance between rolling wheel and core roller is dwindled gradually simultaneously, and promptly the thickness of annular resilient collar blank reduces gradually, and diameter enlarges gradually, up to forming needed cross sectional shape; Guide roller works to induce the workpiece lopping and increases the stone roller expansion stable, and when workpiece contacted with the signal roller, expression had reached preliminary dimension, and the signal roller sends the smart signal that grinds and stop grinding, and the rolling wheel completion task of rolling returns to the home position.
