Postscript, aforementioned each is electronic, pneumatic actuation element is all also connected with a control module with senser element.
The course of work of this servo hot riveting machine is as follows:
(1) open heating tube heater switch, heating tube starts heating, arrives the temperature setting and stops afterwards.On bed die, put workpiece well, the workpiece sensing switch on bed die detects workpiece (when workpiece sensing switch can't detect workpiece, press this hot riveting machine of starting switch (hereinafter to be referred as " machine ") and do not move).Press starting switch, machine setting in motion (i.e. " double startup pattern ").First precompressed safety air cylinder is opened, precompressed mechanism drives air cylinder driven to drop to surface of the work workpiece pressing through precompressed lifting, magnetic switch after putting in place on precompressed safety air cylinder is given and is driven up and down signal of assistant cylinder, backform safety air cylinder is opened, servomotor also starts to decline, drive up and down assistant cylinder to die, allow servomotor drive separately backform to decline simultaneously.
(2) when backform fast-descending is to certain position, drive up and down magnetic switch on assistant cylinder to signal of servomotor, servomotor starts to fall slowly, and rivet hot head workpiece pressing riveting post slowly molds the shape of mushroom head.Wherein, in backform decline process, heating tube temperature rises to operating temperature by aforementioned design temperature gradually, rather than remains on operating temperature always, so can save energy environmental protection.In addition, also can according to the spacer conditions of workpiece heat fusion joint, adjust in real time the duty of heating tube, realize single-point temperature control;
(3) after moulding a period of time, enter packing state.The magnetic valve of blowing is opened, start rivet hot head to blow, with time die rapid moulding.
(4), after reaching the time of the setting of blowing, air blowing closed electromagnetic valve, stops blowing.Backform is got back to the position of setting under the drive of servomotor simultaneously, and servomotor slowly moves to top, drives up and down assistant cylinder under the drive of motor, to be also returned to top simultaneously.Now drive up and down the magnetic switch of assistant cylinder allow and drive up and down assistant cylinder ventilation to magnetic valve to a signal, also give a signal to backform safety air cylinder, the locking of backform safety air cylinder.Drive up and down the magnetic switch of assistant cylinder to precompressed lifting, to drive cylinder to a signal, drive precompressed mechanism to rise to top simultaneously.After precompressed lifting drives cylinder to put in place to a signal to precompressed safety air cylinder, the locking of precompressed safety air cylinder, machine completes one-off.
(5) above action is after safe grating is interfered, and the action of whole machine stops, and coordinates this safe grating and aforementioned double startup pattern, can better realize security protection.
(6) repeated above action, circulation running.
In sum, the present invention, by designs such as aforementioned two stations designs (put part, pickup separates with rivet hot station) and safe gratings, can extraordinaryly realize security protection, stops the generation of security incident, and by rivet hot and precompressed are separated, be aided with again air blowing cooling, can guarantee better welding effect, improving product quality, and design by aforementioned temperature control heating, can realize and being rapidly heated, and realize the object of energy-conserving and environment-protective, also can in 15 minutes, complete production preparation.
Below be only concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on rights protection scope of the present invention.
