Summary of the invention:
The purpose of this utility model is exactly at the existing in prior technology deficiency, and the technical scheme of a kind of squeezed riveting system is provided, and this scheme is simple to operate, safe and reliable, need not connect power supply during work, thereby has improved safety coefficient.
This programme is realized by following technical measures: it comprises the squeezed riveting device, source of the gas is connected with reversal valve I by pipeline, reversal valve I is connected with the rear end cylinder, the rear end cylinder is connected with reversal valve II, pipeline between reversal valve II and described source of the gas and reversal valve I also connects, reversal valve II also is connected with hydraulic pump by the gas motor, and hydraulic pump is connected with described squeezed riveting device, and hydraulic pump also is connected with oil cylinder; Pipeline between reversal valve I and rear end cylinder and front end cylinder also connect, and the front end cylinder is connected with reversal valve III, and the pipeline between reversal valve III and described hydraulic pump and squeezed riveting device also connects, and reversal valve III also is connected with oil cylinder.
This programme adopts hydraulic pressure and pneumaticly jointly controls mode, and pneumatic actuation produces hydraulic pressure.It comprises pneumatic, two parts of hydraulic pressure.Reversal valve I with and connect after front end cylinder, rear end cylinder be connected, the oil pressure of front end cylinder and reversal valve III control hydraulic pump, the switching gas of rear end cylinder and reversal valve II control gas motor, the gas motor is connected with hydraulic pump by shaft coupling, and hydraulic pump is connected the oil cylinder work that drives with squeezed riveting device oil cylinder.
In order to guarantee system pressure, reach the purpose of duplicate protection, described source of the gas and lead to reversal valve I and the pipeline of reversal valve II between be connected with pneumatic triple piece, the pipeline between described hydraulic pump and squeezed riveting device is also with overflow valve and connect, overflow valve is connected with described oil cylinder.
Described reversal valve I is the two-bit triplet hand-operated direction valve, and described reversal valve II and reversal valve III are the 2/2-way reversal valve.
The beneficial effect of this programme can learn according to the narration to such scheme, owing to adopt hydraulic pressure in this scheme and pneumaticly jointly control mode, easy to operate, need not connect power supply during work, safe and reliable, have advantages such as squeezed riveting speed is fast, riveting molding is good.
Description of drawings:
Fig. 1 is the squeezed riveting system construction drawing of the utility model specific embodiment.
Among the figure, 1 is the squeezed riveting device, and 2 is the front end cylinder, and 3 is the rear end cylinder, and 4 is reversal valve I, and 5 is reversal valve III, and 6 is hydraulic pump, and 7 is the gas motor, and 8 is reversal valve II, and 9 is pneumatic triple piece, and 10 is overflow valve, and 11,12 is oil cylinder.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
By accompanying drawing 1 as can be seen, the squeezed riveting system of this programme, source of the gas is connected with reversal valve I 4 by pipeline, reversal valve I 4 is connected with rear end cylinder 3, rear end cylinder 3 is connected with reversal valve II 8, and the pipeline that reversal valve II 8 and described source of the gas and reversal valve I are 4 also connects, and reversal valve II 8 also is connected with hydraulic pump 6 by gas motor 7, hydraulic pump 6 is connected with squeezed riveting device 1, and hydraulic pump 6 also is connected with oil cylinder 12; Pipeline that reversal valve I4 and rear end cylinder are 3 and front end cylinder 2 also connect, and front end cylinder 2 is connected with reversal valve III5, and the pipeline that reversal valve III5 and described hydraulic pump 6 and squeezed riveting device are 1 also connects, and reversal valve III5 also is connected with oil cylinder 11.Source of the gas and lead to reversal valve I4 and the pipeline of reversal valve II 8 between be connected with pneumatic triple piece 9.The pipeline that hydraulic pump 6 and squeezed riveting device are 1 is also with overflow valve 10 and connect, and overflow valve 10 is connected with oil cylinder 11.Reversal valve I 4 is the two-bit triplet hand-operated direction valve, and reversal valve II 8 and reversal valve III5 are the 2/2-way reversal valve.
The course of work of this programme is: press supporting squeezed riveting button two-bit triplet hand-operated direction valve 4, and the 2 cavity of resorption air inlets of front end cylinder, piston lifts, and makes 2/2-way reversal valve 5 be in off-state; Rear end cylinder 3 epicoele air inlets simultaneously, piston is depressed, and makes 2/2-way reversal valve 8 be in on-state; Compressed air gas source enters gas motor 7 by pneumatic triple piece 9; Gas motor 7 drives hydraulic pump 6 by shaft coupling and buys oil; Hydraulic oil enters squeezed riveting device 1 oil cylinder, promotes simultaneously to move before the piston, and workpiece squeezed riveting is shaped, and finishes squeezed riveting.
Unclamp squeezed riveting button two-bit triplet hand-operated direction valve 4, front end cylinder 2 cavity of resorptions stop air inlet, depress at the effect lower piston of spring, make 2/2-way reversal valve 5 be in on-state; The hydraulic circuit pressure release; Simultaneously rear end cylinder 3 epicoeles stop air inlet, lift at the effect lower piston of spring, make 2/2-way reversal valve 8 be in off-state; Compressed air gas source stops to enter gas motor 7 by gas circuit three linked piece 9, and gas motor 7 stops the rotation, and hydraulic pump 6 stops to buy oil.
