Description
Technical field
The utility model relates to the Machining Technology field, more particularly, relates to a kind of double end friction-welding machine.
Background technology
Friction-welding machine is to utilize the friction principle of heating that two metals are treated the equipment that the end face of weldment welds together, it treats that by one of motor-operated rolling clamp clamping weldment rotates, another of master cylinder promotion movable clamp clamping treats that weldment is near the weldment for the treatment of that rotates, at two after weldment contact, by two phase mutual friction heating, pressurizations for the treatment of weldment, make two to treat that weldment produces plastic deformation, surface activation and recrystallization and forms welding point at abrasive end face, to realize two welding for the treatment of weldment.
The double end friction-welding machine is a kind of of outbalance in the friction-welding machine, structure and the course of work of double end friction-welding machine are: treat weldment with one of fastening clips clamping in the middle of the lathe bed, each side there is one of the rolling clamp clamping to treat weldment, rolling clamp is fixed on the unit head, hydraulic system propulsion power head with fast forward speed faster to intermediary movements, this moment, rolling clamp did not rotate, treat that in both sides weldment moves to when treating the weldment certain distance apart from the centre, the translational speed of unit head is converted to work speed by fast forward speed, when both sides until weldment all with the centre after weldment contacts, the weldment for the treatment of of both sides treats that with the centre weldment separates certain distance again, then the weldment for the treatment of of motor drives both sides rolling clamp clamping rotates, and after speed stably, makes both sides treat that weldment treats weldment with work speed near the centre again until its rise of rotational speed, begin spin friction after the contact, friction finishes after a period of time, and certain dwell time is passed through in the pressurize of beginning upset again, anchor clamps unclamp treats weldment, and welding is finished.Like this carried out F.F., worker advance, contact, separate, rotate, again the worker advance, after the friction, the several duties of upset, treat weldment and the middle weldment for the treatment of of both sides have just been realized welding by the mode that friction is heated.
The double end friction-welding machine mainly contains two kinds of control modes at present: a kind of take PLC as core, and the sequence of movement of control double end friction-welding machine; The distributed control mode of the PLC+IPC (industrial computer) that a kind of employing is more advanced.In above dual mode, all be to adopt travel switch to locate to treat weldment, the conversion that realizes duty by reading the travel switch signal (namely needs to install travel switch in each state switching position, when unit head moves to the state switching position, unit head pressing travel switch, travel switch generation signal is to control device, control device control double end friction-welding machine switch operating state), but in the different situation of the length specification for the treatment of weldment, the processing technology for the treatment of weldment requires (the initial motion position of unit head for example, the unit head translational speed, the anchor clamps state, friction shortening amount etc.) difference, travel switch just need to change its installation site on fuselage according to technological requirement, that is to say the length for the treatment of weldment in case change, travel switch all will be reinstalled, and brings very large inconvenience to welding.
In sum, how to provide a kind of double end friction-welding machine, can't convenient measurement treat the weldment position to solve, the not high problem of double end friction-welding machine automaticity is present those skilled in the art's problem demanding prompt solution.
