Abstract
A friction welding machine is composed of machine body, mainshaft box, welding frame, master motor, master cylinder and rotational fixture.
Description
Technical field
The invention belongs to welding field, relate in particular to a kind of friction welding apparatuses.
Background technology
Friction welding (FW) (friction welding) is a kind of press welding method, it is under external force, utilize relative fricting movement and the mobile heat that is produced of plasticity between the weldment contact-making surface, make contact-making surface and near region metal thereof reach the visco-plasticity state and produce suitable macroscopical plastic deformation, finish welding by phase counterdiffusion between two layers of material and dynamic recrystallization.
Typical Continuous Drive Friction Welding machine structure, soldered part is separately fixed at the two ends of welding machine, the rotation of one side drive driven by motor part, dragging another part worker at the opposite side hydraulic cylinder advances, make the contact of two parts, friction generates heat mutually between part makes metal reach intermolecular combination to finish welding.This kind welding machine is owing to be subjected to welding the restriction in space, can only carry out the welding of the less part of size, when the size difference of two parts is bigger, for example a small size conduit is friction welded to above the bulky container, the friction-welding machine of this structure is just powerless.
Summary of the invention
The object of the present invention is to provide a kind of can carry out friction welding that physical dimension differs huge part friction welding apparatuses.
The present invention is by lathe bed, main spindle box, welding support, main motor, master cylinder, compositions such as rolling clamp, its characteristics are: welding support and lathe bed are fastened on lathe bed one side with bolt, tie-bar on the welding support is connected with the master cylinder bearing, main spindle box is connected with lathe bed by the slide unit guide rail, be positioned at the middle part of lathe bed, main motor on the main spindle box links to each other with main shaft by belt, main shaft is by the hydraulic brake on it, clutch is realized rotation, stop, rolling clamp is connected the front end of main shaft, be self-centering three-jaw Wedge-type, can come clamping different-diameter workpiece by changing rest shoe, master cylinder utilizes bolt to be connected by support and lathe bed, is fixed on the opposite side of lathe bed, and the tie-bar on the oil cylinder links to each other with welding support, the piston rod of master cylinder links to each other with main spindle box by ring flange, realizes the F.F. of main spindle box, the worker advances, rewind down.
The function of each several part is: lathe bed is an agent structure of the present invention, all mounted thereto of all parts; Main spindle box transferring rotational motion, and the braking of realization main shaft; Welding support is used for balance welding axial tension; Main driven by motor main axis rotation motion provides rotary power; Rolling clamp is used for adding clamping of workpieces; Master cylinder is realized the axially-movable and the axial pressure of workpiece.
The invention solves the big part friction welding problem of size, have that equipment is simple, a processing ease, energy savings, joint welding quality advantages of higher.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a vertical view of the present invention;
Fig. 3 is a welding position of the present invention partial enlarged drawing.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further specified:
As depicted in figs. 1 and 2, master cylinder 4 is fixed on a side of lathe bed 1 by cylinder support 5, the oil cylinder piston bar links to each other with main spindle box 8 by flange 3, main spindle box 8 be fixed on guide rail 2 above, can endwisely slip along guide rail 2, realize the loading of friction pressure in the welding process in the welding process by the axially-movable of master cylinder 4 pistons, guide rail 2 is fixed on the middle part of lathe bed 1, main motor 7 is fixed on the top of main spindle box 8, to rotatablely move by belt 6 passes to main shaft, drives rolling clamp 10 rotations, and welding support 11 is by being bolted to the left side of lathe bed 1, pull bar 9 links together welding support 11 and master cylinder bearing 5, is used for transmitting the welding axial tension.
As shown in Figure 3, welding support 11 fits tightly with part 12 to be welded, is used for resisting friction pressure and upsetting force in the welding process, and undersize part conduit 13 is connected with rolling clamp 10 by mandrel 14.The process of utilizing the present invention to carry out friction welding is: adjust the level of welding machine and the centering of realizing workpiece centre, in the hole of a taper of the big part 12 position processing to be welded of size, the diameter in hole and angle match with the conical surface of small size part conduit 13; Adjust the position of part 12, make hole concentric on rolling clamp 10 and the part 12; Part 13 is passed the hole of processing from part 12 inside, be fixed on above the rolling clamp 10 by mandrel; Main motor 10 begins to drive main shaft and rotates at a high speed, the main spindle box of the piston of master cylinder 4 drive simultaneously advances to the right side of welding machine worker, rolling clamp 10 drives parts 13 worker that rubs on one side and advances, rotation at a high speed on one side, the conical surface of hole on the part 13 and part 12 closely contacts mutually, produces sufficient frictional heat; Behind the certain hour, main shaft carries out urgency and stops braking, drops to zero from operating rate rapidly in this stage speed of mainshaft; Master cylinder 4 keeps the axial force of certain hour, carries out the upset pressurize, finishes welding.
