Description
Technical field
The present invention relates to a kind of Working pressure cylinder that is used to be configured on the mini-type punching equipment.
Background technique
At present, dispose a kind of hydro-pneumatic pressure transformation that adopts pure pneumatic split combining form in the part punching equipment, this hydro-pneumatic pressure transformation is made up of the air over hydraulic intensifier that a Working pressure cylinder and are used for doing pressure cylinder applied thrust to this, be formed by connecting by pressure hose between air over hydraulic intensifier and the Working pressure cylinder, pressure hose can be according to using needs to have multiple length model, therefore the surface structure form is light and handy, be convenient to any angular position and install, thereby can adapt to multiple complicated dynamic environment.The design that the internal structure of Working pressure cylinder has adopted hydraulic oil and pressurized air to isolate fully, by configure dedicated gas circuit and control valve, guaranteed piston rod automatic tripping force stroke after the contact workpiece of Working pressure cylinder, and possesses F.F. power and return power is little, travel speed is fast, and the buffering that force-stroke power is big is soft to bit function.
Shown in accompanying drawing 1, hydro-pneumatic pressure transformation on the punching equipment adds man-hour press-fiting, pressurized air enters cylinder barrel 103 via the gas circuit switchover control valve 102 on the rear end blind flange 101, fast driving reinforcement piston rod 104 rear portions, metal spring 106 and step-up system piston 107 are moved, make the high pressure oil of the step-up system shoe cream room 108 of precompression, enter the high-pressure oil passage 110 on the step-up system front end flange lid 109, and by high pressure oil interface 109a and high pressure oil interface 201a, connect by pressure hose hydraulic oil is entered in the high-voltage oil cavity 202 on the Working pressure cylinder rear end blind flange 201, the rear portion of piston 204 pushes the work forward, the guide pin bushing 206 that working piston 204 is being prolonged on cylinder barrel 203 inwalls and the front end flange lid 205 is guiding fortune merit, when working piston 204 preposition moulds are being implemented to press-fit when contact workpiece meets obstructions in the working procedure, reinforcement piston rod 104 compressed metal springs 106 on the step-up system enter in the high-pressure oil passage 110 of sealing anterior thin rod part branch, and at this moment high pressure oil produces huge stamping press owing to the conversion of hydraulic coupling area ratio is delivered under the squeezing action to working piston 204.Resistance transfers kinetic force of friction to when stamping press overcomes stiction, hydro-pneumatic pressure transformation is by compressed air-driven in this process, because the compressibility of gas in the hydro-pneumatic pressure transformation, for the working piston 204 in reinforcement piston rod 104 in the cylinder barrel 103 and the cylinder barrel 203, in process and return motion, the compression of gas is very fast with the striking velocity that is released in generation in the cylinder, because gas and liquid fluidity, compressible difference great disparity, the high pressure oil that forms compressed air-driven has little time to replenish, so oil pressure descends fast, if the reaction force of load this moment strengthens, oil pressure will be not enough to continue to drive working piston and move ahead, promptly stop to move ahead, at this moment resistance has been got back to both workpiece preloading conditions of stiction again, wait for that pressurized air boosts once more and continue to promote oil pressure and raise to form and overcome stiction once more resistance is transferred to kinetic force of friction, produce new force-stroke.So pause, boost, move ahead and back and forth take place, promptly becoming hydro-pneumatic pressure transformation press-fits in the working procedure in longer force-stroke and one fast one creeping phenomenon slowly occurs, the operation that can not effectively link up, the impact that becomes repeatedly when serious moves ahead, so the big build-up of pressure of change in resistance is extremely unstable.
Summary of the invention
In order to overcome the deficiency that prior art exists, the object of the present invention is to provide a kind of Working pressure cylinder of stable and reliable operation.
For reaching above purpose, the invention provides a kind of Working pressure cylinder that is used for mini-type punching equipment, it comprises rear end cylinder barrel and front end cylinder barrel, the rear end of rear end cylinder barrel is provided with the rear end blind flange, the front end of front end cylinder barrel is provided with the front end flange lid, is provided with the spacer flanger lid between rear end cylinder barrel and the front end cylinder barrel; Be provided with floating piston in the cylinder barrel of rear end, floating piston will be divided into rear end back cavity and rear end ante-chamber in the cylinder barrel of rear end, the rear end blind flange is provided with the rear end blind flange interface that is connected with the rear end back cavity, and spacer flanger covers and is provided with second spacer flanger lid interface that is connected with the rear end ante-chamber; Be provided with working piston in the front end cylinder barrel, working piston is divided into front end back cavity and front end ante-chamber with the front end cylinder barrel, front end flange covers and is provided with the front end flange interface that is connected with the front end ante-chamber, and spacer flanger covers and also is provided with first spacer flanger lid interface that is connected with the front end back cavity; Be connected by the hydraulic electromagnetic throttle valve between second spacer flanger lid interface and the front end flange interface, the rear end blind flange interface and first spacer flanger cover interface and are connected to source of the gas or oil sources respectively.This composite structure has thoroughly changed the gas-liquid fluid motion mode of Working pressure cylinder, and this gas-liquid loop has thoroughly solved the puzzlement of Working pressure cylinder creeping phenomenon in growing apart from the force-stroke process.Owing to adopted above technological scheme, make the hydro-pneumatic pressure transformation stable and reliable operation, overcome in the prior art and creeped, impacted problem such as move ahead.
