Description
The utility model relates to a kind of clincher tool of hardware, is applicable to that particularly hardware connects and locking hydraulic pressure ring-grooved rivet riveting gun in the vibratory equipment.
In the past,,, continue to use connected modes such as rivet hot or welding as the hardware of vibratory sieve for the vibratory equipment of big dynamic load always.The rivet hot bonding strength is low, complex process, labour intensity are big; Though welding procedure is simple, be difficult to elimination for the welding stress and the welding deformation of large-scale vibrating equipment hardware.
At present, the hardware of external vibratory equipment adopts a kind of novel non-removable ring-grooved rivet cold riveting to connect, and has very high bonding strength and anti-loosening property, and riveting process is simple, easy to operate, efficient is high.As early eighties, the vibratory sieve that China introduces from West Germany KHD company all is to adopt ring-grooved rivet to connect, and has introduced annular groove riveting gun device with this screen(ing) machine.Tangshan Subinst, Coal Science Research Central Inst was developed into aforementioned similar HTS type hydraulic pressure annular groove riveting gun with Bangbu, Anhui Province Engineering Machinery Plant in 1989, it is made up of the muzzle and the body of a gun.Muzzle comprises mould anvil, chuck sleeve, three-jaw and discharging push rod; The body of a gun comprises oil cylinder, piston, handle, hydraulic oil inlet, low pressure oil inlet and push rod displacement oil duct.After the riveted joint, make push rod displacement oil duct cut-in pressure oil, and pushing discharging push rod, rivet point is ejected from three-jaw.The riveting gun complex structure of this band discharging push rod because of being provided with the oil duct of specializing in the push rod displacement, makes the oil duct processing difficulties of oil cylinder piston; When push rod unloaded rivet point, its rivet point spued and has some setbacks, and push rod is flexible; Often leakage of oil in use increases the repair and maintenance workload.
Task of the present utility model is improved above-mentioned hydraulic pressure annular groove riveting gun, and a kind of hydraulic pressure annular groove riveting gun of cancelling the discharging push rod is provided.
Its main points are to remove the discharging push rod that is connected on the oil cylinder piston, and specialize in accordingly after the push rod displacement oil duct, the three-jaw chuck that folder unloads rivet point is set, the anterior inboard conical surface of the conical surface of this three-jaw chuck front portion and chuck sleeve joins, and the three-jaw chuck rear end contacts in order to transmit follow-up sleeve, spring and the rubber ring that folder unloads the rivet tail force.Directly pass piston with the low pressure oil circuit, drive follow-up sleeve, spring and rubber ring, make three-jaw chuck discharge rivet point, and come off automatically.
No push rod hydraulic pressure annular groove riveting gun structure is greatly simplified, and processing and manufacturing is easy; Oil-proof in operating process, the rivet point that spues is very smooth, improves riveting gun service life and work efficiency.
Be described in detail the utility model structure and embodiment below in conjunction with accompanying drawing.
Fig. 1 represents not have push rod hydraulic pressure annular groove riveting gun front section view.
Fig. 2 represents not have push rod hydraulic pressure annular groove riveting gun riveting process procedure chart.
As the no push rod hydraulic pressure annular groove riveting gun that Fig. 1 represents, formed by muzzle, oil cylinder 17 and handle 25.Muzzle comprises mould anvil 39, is provided with circle cover 1 in the porch of mould anvil, the top cover 2 that is connected with the circle external threading, and chuck sleeve 38 is inserted on this top, and the afterbody of chuck sleeve is to be threaded on the oil cylinder piston 10; The three-jaw chuck 3 that folder unloads rivet point is packed in the chuck sleeve, and its front end overlaps with the top and contacts, and the conical surface of three-jaw chuck front portion contacts with the inboard conical surface of chuck sleeve front portion; The rear end of three-jaw chuck joins and unloads the follow-up sleeve 4 of rivet tail force in order to transmit folder, and joins successively and be enclosed within spring 37, rubber ring 36 on the sleeve 6.The afterbody of mould anvil 39 is connected with the front end of oil cylinder 17 by separating annulus 9, fixed muffle 8 and branch sleeve 11, at branch sleeve and piston, oil cylinder inner surface contact position ring washer and O shape rubber seal is set.On in-oil cylinder piston 10 pressure-relief valve 18 is housed, this piston is divided into ante-chamber 14, back cavity 19 with oil cylinder.In the front portion of oil cylinder high-pressure oil pipe joint 33 is housed, in the riveted joint process, this joint and Hydraulic Station high-pressure oil passage join, and its high-pressure oil passage leads to ante-chamber 14; At the rear portion of oil cylinder low pressure pipe joint 32 is housed, when riveted joint finishes discharging, joins with Hydraulic Station low pressure oil circuit, its low pressure oil circuit leads to back cavity 19.Rear portion at oil cylinder is tightly connected with oil cylinder cover 20, and the tail end of oil cylinder is threaded with lock sleeve 21, and tightens up locking with round nut 22; Lock sleeve 21 is threaded with handle 25, and fixing locking with jackscrew 23.Device riveting gun gauge tap 26 on the handle 25, the power line 27 on this switch when work and the control panel of Hydraulic Station be connected.
The utility model riveting process process of representing as Fig. 2.The power line 27 of the riveting gun switch of at first Fig. 1 being represented 26 is connected with the control panel on the Hydraulic Station, and high-pressure oil pipe joint 33, low pressure pipe 32 are connected with the corresponding high-low pressure oil pipe of Hydraulic Station respectively, follow these steps to riveted joint then:
Ring-grooved rivet 12 in A, the workpiece 13 of will packing into puts rivet cover 15, and rivet point 16 inserts in the three-jaw chuck 3 by the circle cover 1 and the top cover 2 of riveting gun muzzle, presses the gauge tap 26 on the riveting gun handle 25, and riveting gun begins riveting work.
B, hydraulic oil enter ante-chamber 14(Fig. 1 from the front portion of oil cylinder 17), promote piston 10, and chuck sleeve 38, circle cover 1 and top cover 2 that drive and piston connect firmly move simultaneously, three-jaw chuck 3 is under spring 37 power effects, along chuck sleeve to the most advanced and sophisticated slippage of its conical surface, inwardly shrink simultaneously, crimping rivet tail 16 is held ring-grooved rivet.
C, behind piston 10, move the tension rivet, and eliminate the gap between the workpiece 13 and when tightly fitting, hydraulic oil promotes coupling sleeve 11 and drives mould anvil 39 to move to the workpiece direction, mould anvil 39 extruding rivet covers 15, make it to produce plastic deformation, the metal of rivet cover is clamp-oned in the annular groove 24 of ring-grooved rivet 12.
