Abstract
The invention discloses a technology for removing flash of an inner hole in friction welding of hollow steel through oxygen blowing, and relates to a processing technology for the flash formed in an inner hole of a pipe during friction welding of the metal pipe. The technology aims to remove the flash formed in the inner hole in the friction welding process of the hollow steel to ensure the smoothness of the inner hole. In the friction welding process of the hollow steel, the inner hole of the hollow steel is blown with oxygen to remove the flash. The oxygen blowing process is completed by blowing oxygen through a nozzle controlled by an electromagnetic switch controlled by a digital control device. In the friction welding process, high temperature is formed at a workpiece friction position, and oxygen has combustion-supporting function, so that the flash of the inner hole is melted when meeting the oxygen at high temperature, and is removed under the action of the blowing force of the nozzle, and the surface of the inner hole of the hollow steel is not damaged. By the technology for removing the flash of the inner hole in the friction welding of the hollow steel, time and labor are saved, the processing time after the hollow steel is welded is shortened, the production cost is greatly reduced, the production efficiency is improved and the product quality is ensured.
Description
Technical field
The present invention relates to the tubing metalwork in friction welding, a kind of technology of the overlap that forms at the pipe fitting endoporus.
Background technology
Friction welding at present is in industrial extensive use.Because of it possess weldment prepare simple, automaticity is high, cost is low, welding process cleaning, non smoke, no material consumption, can produce the advantages such as welding point of forging.Electricity, oxygen welding are confined to the welding work pieces surface, and friction welding can weld together whole metal solder face.Friction welding machine is generally used in the metal current welding.But, the welding of metal tube, as cored steel by friction welding after, the external diameter of pad and endoporus friction place all can form overlap.The external diameter overlap can carry out cutting process by machined means such as lathe, grinding machines.And the endoporus of cored steel often needs water flowing when cutter bores, and guarantee that internal orifice dimension is unimpeded; Cored steel is not only thin but also long in addition, and machining apparatus can't be carried out the processing of removing endoporus overlap; Therefore in the process of friction welding cored steel, the overlap that endoporus forms does not still have solution.
Summary of the invention
The present invention will solve the cored steel overlap that endoporus forms in friction welding process, to guarantee that endoporus is unimpeded.
The present invention adopts in the cored steel friction welding process, carries out deburring to the oxygen blast of cored steel endoporus.Because in friction welding process, friction place forms high temperature, and oxygen has combustion-supporting effect, the endoporus overlap becomes dissolubility after at high temperature meeting oxygen, blows power in addition, and the endoporus overlap promptly is eliminated.
The endoporus overlap that the present invention adopts oxygen blowing technology removing cored steel to form in friction welding process promptly saves time and is laborsaving, has shortened the process time after hollow is welded, and greatly reduces production cost, has improved production efficiency, has guaranteed product quality.
Description of drawings
Accompanying drawing is the schematic diagram that cored steel friction welding endoporus overlap oxygen blowing-out removes technology.
Among the figure: 1. friction welding machine 2. numerical control devices 3. cored steel endoporus 4. cored steels one 5. external diameter overlaps 6. endoporus overlaps 7. cored steels 2 8. nozzles 9. oxygen cathetes 10. magnetic valves 11. source of oxygen
The specific embodiment
Utilize embodiment shown in the drawings to be further described below.
Embodiment at first with reference to the accompanying drawings narrates the working condition of friction welding machine 1.1 statement friction welding machine among the figure because of friction welding machine 1 is a mature technology, has represented just that in the diagram friction welding machine 1 and the one that endoporus overlap oxygen blowing-out removes technology concern.Cored steel 1 and cored steel 27 clampings are on friction welding machine 1 anchor clamps among the figure, and cored steel 1 is corresponding with cored steel 27, and the joint own centre line is represented.During friction welding, cored steel 1 withstands cored steel 27 by the friction welding machine clamp clamps; Cored steel 27 makes two cored steel drill steels 4,7 be controlled by numerical control device 2 in centerline generation friction, weldment friction by the rotation of friction welding machine 1 clamp clamps, friction produces high temperature cored steel 1 and cored steel 27 is welded together, and causes weldment external diameter overlap 5 and endoporus overlap 6.
Secondly the embodiment shown in reference to the accompanying drawings narrates oxygen blowing-out deburring technology.Oxygen blows equipment and is made up of numerical control device 2, source of oxygen 11, oxygen cathete 9, magnetic valve 10 and nozzle 8.Numerical control device 2 had both been controlled the procedure of the workpiece 4,7 of friction welding, also controlled the oxygen therapy program.In to workpiece 4,7 friction process, workpiece 4,7 rubbing surfaces of centerline form high temperature, and external diameter and endoporus 3 form overlap 5,6 respectively.External diameter overlap 5 can carry out the machined cutting process by means such as lathe, grinding machines.When endoporus overlap 6 formed in friction high temperature, numerical control device 2 control magnetic valves 10 switches were by oxygen therapy source 11, and oxygen cathete 9 is to nozzle 8 oxygen therapys.To workpiece endoporus 3 spray oxygen, after meeting oxygen, the endoporus overlap 6 that high temperature forms becomes dissolubility, nozzle 8 blows power in addition, endoporus overlap 6 is eliminated through nozzle 8.
Embodiment shown in reference to the accompanying drawings narrates concrete processing work technical process once more.Remove the endoporus overlap with D45/T45 cored steel drill steel friction welding oxygen blowing-out and be processed as example.
D45/T45 cored steel drill steel:
Material: 22SiMnCrNi2Mo+F710,
External diameter Ф 46, internal orifice dimension Ф 16.
Oxygen pressure 1.1Mpa.
In friction welding, D45 cored steel drill steel 4 and T45 cored steel drill steel 7 clampings are on friction welding machine 1 anchor clamps, and D45 cored steel drill steel 4 is corresponding in centerline with T45 cored steel drill steel 7.Friction welding machine 1 clamp clamps D45 cored steel drill steel 4 withstands T45 cored steel drill steel 7, and friction welding machine 1 clamp clamps T45 cored steel drill steel 7 rotates, and two cored steel drill steel 4,7 corresponding frictions produce high temperature.On friction-welding technique, claim three grades of frictions.Undertaken by numerical control device 2 controls.One-level friction 2.5S, secondary friction 4S, the 3rd are upsets, by friction-welding machine 1 anchor clamps workpiece 4,7 are held out against, and it is upset 0S that secondary has rubbed.The endoporus overlap 6 that forms respectively in three grades of friction process also will adopt three oxygen to blow into the row removing by numerical control device 2 controls.Time-delay 2.5S begins to pass through oxygen cathete 9 through nozzle 9 oxygen blast, oxygen blow duration continuity 0.5S by numerical control device 2 control magnetic valves 10 switches during the one-level friction; Secondary friction time-delay 4S begins oxygen blast, oxygen blow duration continuity 1S; Time-delay 0S begins oxygen blast during upset, oxygen blow duration continuity 2.8S.Blow processing technology through peroxide, endoporus overlap 6 is eliminated, and does not also injure endoporus 3 surfaces of cored steel 4,7 simultaneously.The production lot of cored steel drill steel is big, and different processing works is slightly regulated the numerical control time to get final product.
