Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
The present invention as Figure 1-3, a kind of press machine list apical cap list master cylinder pure gas formula stretching mat structure, comprise apical cap 1, base 7, in base 7, apical cap 1 and master cylinder 3 are installed, main shaft 2 is through apical cap 1 and master cylinder 3, it is characterized in that: install blocking device 4, lagging device 5, stroke regulating mechanism 6 below master cylinder 3, lagging device 5, stroke regulating mechanism 6 are connected by main shaft 2.According to described press machine list apical cap list master cylinder pure gas formula stretching mat structure, it is characterized in that: described blocking device 4 comprises locking cylinder and locking cylinder piston rod 18, blocking device 4 is provided with filler opening, filler opening connects fuel tank by return tube 16, when slide block 9 stroke is near BBC, cam switch Controlling solenoid valve is connected, and makes pressurized air enter locking cylinder, promotes locking cylinder piston rod 18 and is blocked by filler opening.According to described press machine list apical cap list master cylinder pure gas formula stretching mat structure, it is characterized in that: described lagging device 5 lower end connects fuel tank, lagging device 5 is provided with one-way valve 15, and the top of lagging device 5 is provided with delayed chamber 17, and the locking cylinder of blocking device 4 communicates with delayed chamber 17.According to described press machine list apical cap list master cylinder pure gas formula stretching mat structure, it is characterized in that: described stroke regulating mechanism 6 is regulated by air cushion stroke adjustment amount 13 and rotating coder 14, the output terminal connecting worm worm gear 11 of motor 10.
As Figure 1-3, the present invention is the pure gas formula stretching mat structure of setting pressure machine base inside to concrete usage mode of the present invention, can adapt to the mould requirement that user is different, is a main function components in press machine product.Blocking device 4, lagging device 5, stroke regulating mechanism 6 are installed below master cylinder 3.Table top size restrictions and chassis interior spatial constraints is no longer confined to structure, the air pressure provided from source of the gas realizes moving up and down of master cylinder 3, the air pressure provided by source of the gas realizes delayed blocking function, the delayed blocking function of pad that stretches is pinned by stretching pad by locking cylinder when lowermost position is put by stretching pad, returning locking cylinder exhaust after certain distance until slide block makes stretching pad move upward, the pad Traffic control system that stretches mainly adapts to different stretching travel, adapt to different moulds, increase the versatility of ejector beam, the pad adjustment that stretches is realized by driven by motor turbine and worm, a main shaft is adopted to install, simplify assembling, be convenient to processing maintenance.
Stretching mat structure is arranged in base 7, has stroke adjustment function, for compressing in press machine stamping process and exiting workpiece.It overlaps master cylinder 3, a set of stroke regulating mechanism 6 by an apical cap 1, two and the pad fuel tank etc. that stretches forms one, is arranged in base 7 by bolt.Stretch and pad the working principle of master cylinder: when air cushion rises, by electrical control, solenoid valve obtains electric, pressurized air enters air cushion master cylinder 3, and promote piston 8, air cushion slowly rises, drive on apical cap 1 and move, produce power upwards, when slide block 9 runs downwards, in mould, ejector beam can be descending with air cushion, thus pressure-pad-force is produced to stamping part, slide block 9 backhaul upwards time, it is up that apical cap 1 promotes ejector beam, can play the effect ejecting stamping part.The working principle of stroke regulating mechanism: when regulating air cushion stroke, the associated button on start-up operation station, motor drives worm and worm gear 11, drives screw sleeve 12 to move up and down, thus changes the upper limit position of air cushion.The size of air cushion stroke adjustment amount 13, is measured by rotating coder 14, can on active station numerical monitor, regulated quantity reaches lower dead centre.The working principle of delayed locking mechanism: lagging device 5 makes the delayed cylinder oil-feed pressurize of lagging device 5 by the locking cylinder of gas control blocking device 4, obtains air cushion backhaul delayed.When air cushion starts to down stroke, the locking cylinder of blocking device 4 is failure to actuate, hydraulic oil enters delayed chamber 17 by the one-way valve 15 on the delayed cylinder piston of lagging device 5 and return tube 16, when slide block 9 stroke is near BBC, cam switch Controlling solenoid valve is connected, and makes pressurized air enter the locking cylinder of blocking device 4, promotes locking cylinder piston rod 18 and is blocked by the delayed cylinder filler opening of lagging device 5, form high pressure in the delayed cylinder of lagging device 5, make air cushion can not backhaul.In this process, there is one section of fluid column to be pushed into delayed chamber 17, make delayed descent of piston one segment distance, drive apical cap 1 to form deflection.When slide block 9 backhaul is to certain altitude, cam switch Controlling solenoid valve ends, and the locking cylinder exhaust of blocking device 4, the oil in the delayed cylinder of lagging device 5 is got back in casing through return tube 16, the delayed cylinder release of lagging device 5.Air cushion apical cap 1 backhaul under the effect of master cylinder.
Embodiment recited above is described the preferred embodiment of the present invention; not design of the present invention and protection domain are limited; under the prerequisite not departing from design concept of the present invention; the various modification that in related domain, common engineers and technicians make technological scheme of the present invention and improvement, all should fall into protection scope of the present invention.
