Description

Pneumatic stamping machine

The utility model belongs to the forcing press field, refers in particular to a kind of pneumatic stamping machine.

The prior art that the utility model is quoted is: the mechanical group in Hong Kong once produced a kind of gas hydraulic cutting presser that is called and was the machine of pneumatic press in fact.It is made of cylinder, actuating arm, stroke screw rod, adjusting screw, slide block, column, body, base, back of the body seat, magnetic valve, two gauge taps, foot switch etc., and wherein base is a square.Its operation principle is: the pressure that produces ton with the compressed air-driven of low pressure (having only about 10 crust), pure pneumatic fast travel makes mould quick little power ground contact workpiece when idle stroke, after mould is run into workpiece, machine transfers the reinforcement stroke automatically to, workpiece is carried out all one's effort riveting, after riveting is finished, start backstroke, the mould returning quickly belongs to the soft of a kind of advanced person and puts in place and adaptive technique; During use, connect source of the gas and power supply, machine still keeps static silent state, harmless source of the gas when static, no power consumption phenomenon, select gauge tap (comprising that hand is used and pin is used) then, cylinder intake, ram travel is mentioned, two gauge taps about two hands are pressed simultaneously, cylinder is given vent to anger, slide block down, machine work done.But this machine only is used for beer lid riveting, can't be used for other stamping press, all adopt the automatic production line operation owing to produce the producer of beer now, so this machine has just been eliminated automatically also.And, this machine precision is low, stroke is poor with base worktable face perpendicularity up and down for slide block, column is improper with body design assembling, and the stroke of design is low, has limited mold height, the incompatibility diel is installed, though therefore used advanced soft putting in place and adaptive technique, and have that power consumption is lower, advantage such as nonpollution environment phenomenon, noise are little, also be difficult to replace the forcing press of existing other type.

The forcing press that China produces now is most of with motor as power (electrically powered press) and oil liquid pressure machine (hydraulic press).The forcing press of motor as power, noise is big, and safeguard protection is undesirable, and impact shock power is strong, and power consumption is big, is 1.1KW as 6.3 tons the motors that forcing press mated, not work done of forcing press sometimes, motor is wasted electric energy also in running.Oil liquid pressure machine or with the forcing press of other liquid promotes hydraulic oil cylinder driving with motor, and its build is big, and efficient is low, is easy to generate the phenomenon of leakage during work done.Therefore, they all are not suitable for the production line assembling process.

" gas-liquid fly press " (ZL85200347 stops) is used for forging and pressing and produces, and by the gas-powered impulse stroke, the hydraulic pressure backhaul does not belong to the pneumatic press type.

The purpose of this utility model is to provide a kind of pneumatic stamping machine; it in high efficiency, the handling safety performance is good, environmental protection effect is good, handsome in appearance, energy consumption is little, lathe precision height and long service life; purposes is wide, is specially adapted to modern production assembly line.

For achieving the above object, the solution that the utility model is taked is: become a kind of pneumatic stamping machine after the pneumatic press that prior art gas hydraulic cutting presser promptly is used for beer lid riveting improves, comprise cylinder, actuating arm, stroke screw rod, adjusting screw, slide block, column, body, base, back of the body seat, magnetic valve, two gauge taps, foot switch, air cleaner is housed below magnetic valve, compressed air enters cylinder after entering magnetic valve by air cleaner, has two T type grooves on base.

Body is installed in the centre of column.

The workbench of base is through correct grinding.

Because the utility model integrates the moulding advantage of the pneumatic principle and the electric press machine of prior art, therefore have following good effect:

1, because air cleaner is housed, guarantees the gas no-sundries effectively, improved the service life of cylinder.

2, base has two T type grooves, is convenient to mould and installs, and has improved operating efficiency.Prior art will be fixed on counterdie on the work top with special fixture, and is very loaded down with trivial details.

3, body is installed in the centre of column, has improved range-adjustable, and high-stroke has enlarged diel accommodation, can satisfy some high-stroke punching press needs; Change different moulds or different workpieces, need not to carry out the machine stroke adjustment; Compared with the prior art, expanded range of application widely.

4, energy-conservation.Specified power consumption is 3W only, compares with the forcing press of other type, has saved energy widely.

5, the handling safety performance is more reliable than existing electrically powered press.Two hands are not pressed two gauge taps simultaneously, and machine just can not work done, guarantees operative employee's safety.

6, environment protecting is better than existing electrically powered press and hydraulic press.Once being only to need to drive and need not hydraulic system and can produce and reach 1 ton stamping press, there is not leakage and problem of environment pollution caused with the compressed air about 10 crust; The 2nd, stamping press is in the following step-less adjustment of rated maximum, pure pneumatic F.F. stroke makes mould quick little power ground contact workpiece when idle stroke, after mould was run into workpiece, cylinder just automatically transferred the reinforcement stroke to, and workpiece is carried out all one's effort punch process, after finishing punch process, start backstroke, the mould returning quickly vibrates little, noise is little, has improved punching operation worker's working environment widely.

7, good looking appearance, the precision height.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.

Accompanying drawing 1 is the structural representation of present embodiment.
