Description

A kind of Intelligent automatic rectangular tube, bar polishing unit

Technical field

This utility model relates to numerically controlled intelligent technical field, be specifically related to a kind of Intelligent automatic rectangular tube, Bar polishing unit.

Background technology

Metal material surface polishing is different from polishing, there is not significant metal loss.Metal surface polishing Processing method has a variety of, but uses more only mechanical polishing, chemical polishing and electricity in the industrial production Chemical polishing.And mechanically polishing is the most ancient processing method having use value most in three.

Mechanical polishing process had both had the shear action of machinery, had again physics and the effect of chemistry.Buff wheel exists Doing high speed rotary motion, operator imposes suitable pressure to polished metallic article surface, is pressed On buff wheel, now, produce high temperature due to rubbing action, make polished metallic article surface easy Plastic deformation is occurred to form one layer " affected layer ".But the work of the frictional force at buff wheel high speed rotating Under with, some projection on the most polished metallic article surface is shaved, the most polished gold Belonging to article surface and also can produce plastic deformation, boss is pressed into, or inserts depression after a mobile segment distance Position.This cutting convex fills out recessed flattening course, is repeated that (i.e. metal surface exists the most on a large scale Very thin oxide-film that the oxidation lower moment of ambient atmosphere is formed is the most polished to get off), add antiscuffing paste Lightization effect, makes the most rougher polished metallic article surface smoothened and bright (the highest Brightness---bright in mirror surface).

For above-described " affected layer ", Raether and Kranert proposed as far back as nineteen forty-three " affected layer illustraton of model ", is the most still accepted by people.This model is thought, article surface is processed Impact and there is various deformation so that the crystal grains fine on top layer, density becomes big, and compactness improves, its knot Structure and amorphous state are without much differences, thus surface becomes the most smooth and bright.The thickness of affected layer Degree is not constant, and it is as material, processing method and processing conditions used and changes.

" affected layer " was further subdivided into three types by Song Yongzheng for a long time in 1972:

(1) effect of extraneous element and the metamorphic layer extraneous element that formed mainly pass through: 1. surface contamination； 2. surface adsorption (physical absorption and chemisorbed)；3. the compound that surface is newly formed；4. the embedment etc. of foreign body Mode enters finished surface, and makes machined surface layer change in the course of processing on recurring structure occur adding Work metamorphic layer.Wherein, embedment and the oxide skin(coating) of foreign body the metamorphic layer formed can affect surface and add subsequently The quality of work.

(2) change of crystalline structure and the metamorphic layer that formed

Following crystalline structure is readily formed metamorphic layer: 1. amorphous surface；2. fine crystal layer；3. turn The surface that bit density rises；4. the surface of twin crystal is formed；5. the surface that a certain composition of alloy covers；6. fine The surface of dimension shape tissue；7. the surface that rubbing down is abnormal；8. the plastic deformation crystallization formed because of processing；9. because of Frictional heat and the recrystallization etc. that causes.

(3) stress and the metamorphic layer that formed

The damaged surface layer that stress metamorphic layer is formed mainly due to the residual stress of product itself.

Current domestic widely used square tube automatic polishing apparatus for production line is mainly made up of array polishing main frame, Metal tube be applicable to various square-sections, bar appearance rough polishing, the processed such as throwing and essence throwing.

The problem analyzing the existence of this square tube automatic polishing apparatus for production line below in terms of six:

First, this equipment uses traditional unidirectional vertical feed of buff wheel, i.e. imitates single movement plane polishing Technological principle, polishes all axial cuts of product surface, and quality of finish is the highest.

Second, this equipment uses simple manual pulley adjusting means, individually adjusts each buff wheel relative to (footpath, position To feeding).

3rd, buff wheel there will be abrasion in continuously work process, and this equipment can not be the most automatic Compensate polishing wheel wear, periodically must adjust buff wheel vertical direction position by closed-down manual.

4th, after the adjustment, each mechanism relative position rigidly fixes this equipment, when indivedual work piece sizes During super large, " stuck " and " overground " phenomenon easily occurs, causes fire to take place frequently.

5th, when this device transform produces description, must adjust the most one by one and often organize horizontal direction and hang down Nogata handwheel on support.

6th, the polishing main frame enclosed construction by their entirety configuration of this equipment, and the production line single concentration of employing Dust suction mode, energy consumption is high, pollutes big, and dust removing effects is general, and production environment is severe, and occupation disease injury is serious.

As can be seen here, the square tube automatic polishing apparatus for production line that this employing regulates manually, time and effort consuming, Production efficiency is low, and automatization level is low, it is difficult to ensures the concordance of quality of finish, and fails to introduce intelligence Change and flexibility designs, it is also difficult to adapt to multi-item production demand.

In sum, really it is necessary to develop a kind of intelligent square tube automatic polishing apparatus for production line.
