Abstract
The utility model relates to the field of press machines and discloses a lower ejector of a press machine. The lower ejector comprises a sliding block mounted on a machine body of the press machine, and a platen is arranged below the sliding block and fixed to the machine body. The ejector is characterized in that the bottom of the sliding block is connected with an ejector rod cross beam through pull rods, an ejector rod is arranged on the upper portion of the ejector rod cross beam, a guide base is fixedly mounted in the middle of the platen, an ejector rod hole matched with the ejector rod is formed in the center of the guide base, a guide base sleeve and a guide sleeve are arranged in the ejector rod hole, and an ejector header is mounted on the top of the ejector rod. The lower ejector is assembled at the bottom of the sliding block, the sliding block moves so that the ejector rod can be driven to move, and a stamping part is ejected out of a die through the ejector rod when the sliding blocks returns, so that the stamping part is disassembled. The lower ejector is simple in structure, convenient to assemble and capable of being used for disassembling parts of the press machines, and working cost is lowered.
Description
Technical field
The utility model relates to a kind of forcing press, particularly a kind of forcing press device for discharging.
Background technology
Bottom ejection device, after forcing press pressing component, during slide block backhaul, plays inloading part effect.Inloading part after existing forcing press pressing component, generally completes by being arranged on square air cushion under fuselage workbench.Air cushion plays flanging and inloading part effect, and general structure more complicated also can increase the overall structure size of forcing press, and need to be equipped with source of the gas and lubricated etc.During for general fixed point location inloading part, adopt air cushion very uneconomical.
Utility model content
The purpose of this utility model is to provide a kind of forcing press bottom ejection device, and it is simple in structure, and it is convenient to assemble, with low cost.
The purpose of this utility model is achieved in that a kind of forcing press bottom ejection device, comprise the slide block being arranged on press frame, described slide block below is provided with platen, platen is fixed on fuselage, the bottom of described slide block is connected with push rod crossbeam through pull bar, the top of push rod crossbeam is provided with push rod, described platen middle part is installed with guide holder, guide holder center offers the jogger hole coordinating with described push rod, in jogger hole, be provided with guiding cover for seat and guide pin bushing, the top of described push rod is provided with top.
In the utility model when work,, press ram is when punching press, and slide block moves down and drives push rod to move down, make push rod hide with guide holder in, when slide block completes after punching press, the slide block backhaul that moves up, drives on push rod and moves stamping parts is ejected, and completes inloading part.Compared with prior art, the beneficial effects of the utility model are, the utility model is by the bottom assembling bottom ejection device by slide block, by the mobile movement that drives push rod of slide block, make slide block by push rod, stamping parts ejection die be completed to inloading part when backhaul, the utility model is simple in structure, easy to assembly, has reduced job costs.The utility model can be used in forcing press inloading part.
In order to increase the scope of application of the present utility model, described pull bar is provided with two, and the bottom of described slide block is provided with holder, and described pull bar and holder are threaded togather, and fix through pull-rod nut.During work, releasing lever nut, the i.e. upper-lower position of capable of regulating pull bar, and replaceable different top.
In order to make the movement of push rod in guide holder more stable, described guide holder is set on guide holder inside front, and described guide pin bushing is arranged on side-lower in guide holder.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein, 1 fuselage, 2 slide blocks, 3 holders, 4 pull-rod nuts, 5 pull bars, 6 platens, 7 push rod crossbeams, 8 tops, 9 push rods, 10 guiding cover for seat, 11 guide pin bushings, 12 guide holders.
The specific embodiment
A kind of forcing press bottom ejection device as shown in Figure 1, comprise the slide block 2 being arranged on press frame 1, slide block 2 belows are provided with platen 6, platen 6 is fixed on fuselage 1, the bottom of slide block 2 is connected with push rod crossbeam 7 through pull bar 5, the top of push rod crossbeam 7 is provided with push rod 9, platen 6 middle parts are installed with guide holder 12, guide holder 12 centers offer the jogger hole coordinating with push rod 9, in jogger hole, be provided with guiding cover for seat 10 and guide pin bushing 11, the top of push rod 9 is provided with top 8, pull bar 5 is provided with two, the bottom of slide block 2 is provided with holder 3, pull bar 5 is threaded togather with holder 3, and fixing through pull-rod nut 4, guiding cover for seat 10 is arranged on guide holder 12 inside fronts, guide pin bushing 11 is arranged on the interior side-lower of guide holder 12.
During the utility model work, press ram 2 is when punching press, and slide block 2 moves down and drives push rod 9 to move down, make push rod 9 hide with guide holder 12 in, when slide block 2 completes after punching press, when slide block 2 moves up backhaul, drive on push rod 9 and move stamping parts is ejected, complete inloading part.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection domain of the present utility model.
