Wherein, a lower end of an output shaft of the gas and liquid boost system is connected with a stroke control mechanism and a press head. Bearing riveted by the pneumatic press has the advantages of high quality, long service life and no noise in operating state.
Description
Technical field
The utility model relates to a kind of forcing press.Be to be used for specifically with the bearing riveted pneumatic press of steel ball riveted in retainer.Also can be used in the operations such as other riveted joint, assembling and stretching in the field of machining.
Background technology
In the bearing processing industry, for the steel ball riveted in retainer, method commonly used is to adopt punch press that the rivet in the mould is carried out disposable quick impact to realize the punching press typing.Adopt punch press that rivet is carried out disposable quick impact, though can realize riveted to bearing, but because the drift of punch press has spacing before impacting and between the rear end of rivet, under the effect of drift, hit the moment of rivet fast at punch press, rivet is tilted, make the two retainers dislocation behind the riveted, the proper circle in pocket hole lose just rate height, riveted is of low quality.Simultaneously, the moment between steel ball and retainer, between steel ball and lasso raceway groove impacts fast, also can cause the scratch of its mating surface, not only can make bearing produce noise under user mode, and service life is not long.
Summary of the invention
The purpose of this utility model is to provide a kind of pneumatic press.With the bearing of this pneumatic press riveted, quality is good, the life-span is long, noiselessness under user mode.
Above-mentioned purpose of the present utility model, realized by following technical solution:
Pneumatic press of the present utility model comprises workbench, and fuselage is arranged on the workbench, is characterized in that the gas-liquid force increasing system is arranged on the fuselage, source of the gas handles system and electric cabinet, and the output shaft lower end of gas-liquid force increasing system is connected to stroke control mechanism and drift.
Adopt such scheme, have the following advantages:
Because have gas-liquid force increasing system, source of the gas to handle system and electric cabinet on the pneumatic press fuselage of the present utility model, the output shaft lower end of gas-liquid force increasing system is connected to stroke control mechanism and drift.On the following plug cock wherein air flue is arranged, this air flue communicates with its lower surface.When inflating in the air flue of downward plug cock, plug cock is driven under output shaft and the drift thereof stretch, until making drift be pressed on the rear end of rivet, thereby finish setting upright to rivet.
Then, inflate in the end cap backward again, the air pressure in the upper chamber is raise.Along with the rising of upper chamber air pressure, upper piston can drive under the upper boom to be stretched.Along with the following of upper boom stretched, the pressure in the lower oil chamber can raise.Along with the rising of lower oil chamber's internal pressure, output shaft can produce a downward power under the drive of lower piston, and this power is applied to through on the rivet of setting upright by drift, thereby has finished the riveted between retainer up and down.
Like this, through set upright earlier, after slowly exert pressure and realized riveted to rivet.Avoided traditional disposable rivet is hit fast make that rivet tilts, the proper circle in the dislocation of two retainers, pocket hole loses positive situation and takes place, and improved the riveted quality greatly.Simultaneously, can not abrade between the mating surface between steel ball and retainer, between steel ball and lasso raceway groove yet, under user mode, not only can not produced noise, also prolong the service life of bearing by the bearing of riveted.
