In such scheme, described hydraulic system comprises two-position four way change valve 8, bi-bit bi-pass reversal valve 9, upper cavity pressure relay 11, cavity of resorption pressure switch 12, unidirectional flow speed control valve 13 and flow speed control valve 14 and hydraulic pump 15, the outlet of hydraulic pump 15 divides three tunnel outputs, one the tunnel links to each other with the inlet of bi-bit bi-pass reversal valve 9, and the outlet of bi-bit bi-pass reversal valve 9 takes back oil sump; Another road links to each other with an inlet of two-position four way change valve 8, another inlet of two-position four way change valve 8 takes back oil sump, an outlet of two-position four way change valve 8 links to each other with cavity of resorption in the cylinder body through unidirectional flow speed control valve 13, and another outlet links to each other with epicoele in the cylinder body; Third Road links to each other with hydraulic motor 1,8 transpositions of described upper cavity pressure relay 11 control two-position four way change valves, 9 transpositions of cavity of resorption pressure switch 12 control bi-bit bi-pass reversal valves.
Operation principle of the present utility model is: the primer fluid pressing system, pressure oil enters cylinder body 3 epicoeles through two-position four way change valve 8 right positions, driven plunger 2 is descending, bi-bit bi-pass reversal valve 9 enters right position simultaneously, cut off oil circuit, pressure oil enters hydraulic motor 1 through another road oil filter 10, drive hydraulic motor 1 rotation, after arriving riveting pressure, upper cavity pressure relay 11 sends signal, and 0-1 is after second in time-delay, 8 outages of notice two-position four way change valve, pressure oil enters cylinder body 3 cavity of resorptions through position, two-position four way change valve 8 left side, and driven plunger 2 is up, to top dead-centre.Cavity of resorption pressure switch 12 sends 9 outages of signal notice bi-bit bi-pass reversal valve, and pressure oil is got back to fuel tank, hydraulic motor 1 stall through position, bi-bit bi-pass reversal valve 9 left side.Thereby finish the riveted joint of a rivet in second at 2-4.
The utility model is compared with traditional fluid pressure type riveting pincers and is had the following advantages:
One, the riveted joint surface quality is good, and riveted joint rear surface roughness can reach Ra1.25.
Two, riveting intensity height, because the utility model adopts radial rivet and pendulum to roll over riveting technology, the distortion of rivet be obedient to the metal spontaneous current to, almost do not have the metallic fiber knurl and fracture, so riveted joint back intensity is riveted far above traditional pressure type, as: suspension type hydraulic pressure riveting pincers, air pressure gun, hammer machine etc.
Three, energy and labour saving, owing to adopt radial rivet and pendulum to roll over riveting technology, riveting pressure only is the 1/12-1/15 of suspension type hydraulic pressure riveting pincers etc.Especially for the big rivet more than the Φ 16mm, need not to add hot riveting, energy-saving and cost-reducing, pollution-free.
Four, easy to operate, labour intensity is low.
Five, cold riveting rate height, noiseless, friction.
Six, in light weight, only be the 1/5-1/6 of suspension type hydraulic pressure riveting pincers.Cost only is the 50%-60% of suspension type hydraulic pressure riveting pincers, and need not supporting supercharging equipment.
