Abstract
The utility model discloses an air-pressure floating type perforating bullet press-fitting device, which comprises a press sliding block, a die holder, a male die, a lower die sleeve, a bottom plate and a cylinder, wherein the die holder is arranged in a cylinder sleeve of the cylinder; the cylinder sleeve is hermetically connected with the press sliding block; and the male die is connected with the die holder through a connector. According to the utility model, the male die is press-fitted in an air-pressure floating mode. The press-fitting device achieves slow boosting in the process of traveling down, thereby avoiding the phenomenon that a liner cracks due to instant large pressure. When the male die is depressurized and travels up, the press-fitting device achieves slow pressure relief, while stopping the generation of negative pressure and solving the problem that the liner comes off in the press-fitting process.
Description
Technical field
The utility model relates to the floating type perforating bullet press-loading apparatus of a kind of air pressure, be mainly used in the oil gas well with perforating bullet press-fit the manufacturing field, press-fit the problem that cavity liner breaks and takes off cover in the process in order to solve perforating bullet.
Background technology
The operation that press-fits traditional perforating bullet adopts four post explosive-proof hydraulic machines, and the assembling special use press-fits patrix and base, perforating bullet shell case, explosive, cavity liner is press-fited be one, produces the oil gas well and uses special-purpose perforating bullet.
Adopt existing perforating bullet to press-fit operation; Carrying out the oil gas well when press-fiting operation with perforating bullet; Following two kinds of situation often take place: a kind of situation is, because patrix is the fixed loading and unloading of one, moment added on the cavity liner when press pressing pressure contacted cavity liner at upper punch; Cause cavity liner to break, also possibly produce the phenomenon of micro-crack; A kind of in addition situation is, in press-fiting the up process of patrix release, owing between cavity liner and patrix drift, form certain negative pressure, it is incomplete to add the applying of cavity liner and explosive contact-making surface, causes cavity liner to come off, the phenomenon of product rejection.
Summary of the invention
The purpose of the utility model is to overcome existing perforating bullet and press-fits the problems referred to above that operation adopts four post explosive-proof hydraulic machines to exist; Provide a kind of air pressure floating type perforating bullet press-loading apparatus; The utility model adopts that air pressure is floating type to press-fit formpiston; In descending process, reach the effect of slow supercharging, avoided cavity liner moment to bear big pressure and the phenomenon that causes cavity liner to break; When the formpiston release is up, reach the effect of slow release, suppressed the generation of negative pressure simultaneously, solved and press-fited the difficult problem that cavity liner comes off in the process.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is following:
The floating type perforating bullet press-loading apparatus of a kind of air pressure; Comprise press slide, die holder, formpiston, lower die-sleeve and base plate, it is characterized in that: also comprise cylinder, said die holder is arranged in the cylinder jacket of cylinder; Said cylinder jacket and press slide are tightly connected, and formpiston is connected with die holder through connector.
Said die holder is provided with seal groove, is provided with the sealing ring with the cylinder liner internal wall fitted seal in the seal groove.
Said cylinder jacket and the press slide place of being tightly connected are provided with seal groove, are provided with the sealing ring with the press slide fitted seal in the seal groove.
Said connector is a connecting bolt, and connecting bolt passes die holder and is connected with formpiston.
The abutting end of said formpiston and lower die-sleeve is provided with the cover circle, and the cover circle is positioned at the drift top of formpiston.
Adopt the advantage of the utility model to be:
One, in the utility model, said die holder is arranged in the cylinder jacket of cylinder, and said cylinder jacket and press slide are tightly connected; Formpiston is connected with die holder through connector; Adopt that air pressure is floating type to press-fit formpiston, in descending process, can cushion the big pressure of press through the compression of gas in the cylinder; Reach the effect of slow supercharging, thereby avoided cavity liner moment to bear big pressure and the phenomenon that causes cavity liner to break; When the formpiston release was up, gas expanded and exerts pressure to patrix in the cylinder, and male punch is fitted with cavity liner always, reached the effect of slow release, had suppressed the generation of negative pressure simultaneously, press-fited the difficult problem that cavity liner comes off in the process thereby solved.
Two, solved two difficult problems in press-fiting process in the prior art through the utility model, thereby the product rejection rate that makes perforating bullet press-fit production reduces greatly, also improved product quality simultaneously.
Three, in the utility model, said die holder is provided with seal groove, is provided with the sealing ring with the cylinder liner internal wall fitted seal in the seal groove, makes die holder and cylinder liner internal wall sealing effectiveness better.
Four, in the utility model, said cylinder jacket and the press slide place of being tightly connected are provided with seal groove, are provided with the sealing ring with the press slide fitted seal in the seal groove, make cylinder jacket and the press slide can effective seal, thereby improve cylinder efficiency.
Five, in the utility model, said connector is a connecting bolt, and connecting bolt passes die holder and is connected with formpiston, adopts this structure to be convenient to the installation and removal of formpiston.
