Abstract

A multi-purpose pneumatic carving machine cooperates with air compressor to do three-stroke reciprocating movement including impact, press and dust discharge. A pneumatic piston hammer in the machine can do correspondent reciprocating movement to generate monodirectional impact force to do work. Exchanging punching heads can realize carving, riveting, or impact. The air is exhausted from both sides of punching head, which can also performe dust discharge. The punch frequency can be regulated in the range from 300/min to 1200/min. It has self-damping.

Description

Pneumatic multi-purpose graving apparatus

It is power with compressed air that this machine belongs to a kind of, can stepless adjustment frequency of impact and in working order under stepless change impulsive force at any time, but the pneumatic tool of bump formula.Especially a kind of unidirectional percussive pneumatic tool that is exclusively used in engraving, sculpture.

At present, the single beat pneumatic tool that domestic and international application is maximum is a pneumatic stapler etc., and its working method can only be impacted once for whenever opening a switch, and impulsive force is single, and purposes is extensive inadequately.

It is little to the purpose of this invention is to provide a kind of volume, simple in structure, easy to operate, can reconcile frequency of impact (300min time-1200min time) at any time, control impulsive force with feel, automatically weakening, be applicable to the impact engraving of any direction, automatically chip removal can be changed the single beat Pneumatic multi-purpose graving apparatus of multiple drift, so claim this machine to be " omnipotent shock machine " again.The object of the present invention is achieved like this: 1. this device has a cutter hub that can slide vertically, 2. the control system that can change the air inflow of main air valve is provided with gas conversion piston valve in this machine rear end, can close back the air inlet of control chamber automatically, open its transpiration hole, open main gas tank's inlet nozzle simultaneously, close the working gas control system of its transpiration hole and decompression transpiration hole, main gas vent.3. be provided with the vibration insulating system of shock-absorbing spring.4. be provided with that the acting of multiple drift and piston hammer partly forms.

This machine is little with domestic and international similar technology phase specific volume, simple in structure, flexible and convenient operation, the frequency of impact height, the weakening function is good, and feel control impulsive force broad has functions such as vibration damping, chip removal again owing to have multiple interchangeable drift, therefore can to the processing of material thicknesses such as stone, wood, metal all can, can obviously improve effect and alleviate operator's labour intensity.

Below in conjunction with its operation principle of description of drawings: the high-pressure air source of this Pneumatic multi-purpose graving apparatus is provided by air compressor; Press drift 27,26 during use gently, just drive control valve push rod 19 and upwards slide.Main control valve 3 is slowly opened, calm the anger contract body through suction nozzle 1 behind elongated gas porosity, again through main control valve 3 to the groove II13 above the gas conversion piston valve, send into back control and advance to arrange passage 14 inner high voltage gases, in hole 28 arrives back control air chamber to 21, returning control bar 23 will promote piston hammer 11 and move upward under the effect of air pressure, at this moment the gas in the main gas tank 16 is by transpiration hole 9, after aligning, transpiration hole above cylinder block 15 discharges, piston hammer 11 impact strokes accent bar 6 just drives conversion piston valve 5 and upwards compresses spring 7 motions, transpiration hole dislocation on transpiration hole and the cylinder block is closed automatically, at this moment the transpiration hole on air inlet 14 and the cylinder block is in together in the notch 13, returns control bar release of pressure; Inlet nozzle 10 and main gas tank 16 form path simultaneously, gases at high pressure enter rapidly in the main gas tank 16, conversion piston valve 5 pressurizeds upwards compress spring 7 and put in place, piston hammer 11 is subjected to air pressure to promote downward accelerated motion simultaneously, air pressure when piston hammer 11 surpasses decompression transpiration hole 17 in the main gas tank 16 just descends rapidly, piston hammer 11 is high-speed motion bump cutter hub 24, drift 25 actings under action of inertia, the conversion piston valve 5 that is depressurized is subjected to the active force of spring 7 and resets, so just formed an impact stroke cycle, motion and so forth, the engraving machine continuous operation.

Claims

1, this machine is a kind of unilateral conductivity impact type Pneumatic multi-purpose graving apparatus, this machine comprises the feel main control valve, gas conversion piston valve, preceding air chamber, the rear gas chamber of band decompression transpiration hole, the vibration damping back-moving spring, the cup valve returns the control bar, the rear end, stroke is transferred bar, piston hammer, drift, systems such as cylinder body, it is characterized in that: the transpiration hole that gas changes above the piston valve before the work aligns with the transpiration hole of cylinder block upper end, it is indoor that Compressed Gas at first enters back control during work, at this moment piston hammer is incited somebody to action compressed energy-storage shock-absorbing spring vertically, promote the compression of gas conversion piston valve simultaneously and reset and do corresponding sports, the gas main gas tank in discharges by two transpiration holes that align; In the time of in Compressed Gas enters main gas tank, the transpiration hole of main gas tank is closed automatically, and the transpiration hole that goes back to control chamber and cylinder block rear end simultaneously forms path, and main vent is located at the drift both sides, can be used for chip removal.
