The utility model provides a turnover worktable of a hydraulic press. The utility model is characterized in that the lower surface of a slide block is hinged with an upper worktable which can turn over; a fixing seat with a pin hole, which can be locked and a supporting seat are arranged between the slide block, the upper worktable which can turn over, a pin shaft and a locked oil cylinder which drives the pin shaft to make transverse motion; the middle of the slide block is hinged with two rows of turnover oil cylinders which are used for driving the upper worktable to turn over; a hanging hook and a hanging lug are arranged between the piston end of each of the turnover oil cylinders and the back face of the upper worktable; two parallel guide rails which drive the upper worktable to turn over are installed on a lower worktable. The utility model solves the problem that a die is inconveniently installed, repaired and assembled, and work efficiency is improved. In addition, the utility model has the advantages of simple structure and easy production.

Description

Hydraulic press upset workbench

Technical field

The utility model relates to a kind of hydraulic press that is used for the production mould tensioning member, especially a kind of hydraulic press upset workbench.

Background technology

At present mostly the hydraulic press fuselage of production mould tensioning member is mainly frame-type, promptly entablature, sill, two heel posts, and slide block constitute.The slide block lower surface is equipped with upper table, the sill upper surface is equipped with lower table, the upper and lower mould of difference installation mold on the last lower table.Mould needs its on-the-spot repair when first the installation or after a period of time of use, but because the upper-lower position difference that mould is installed, and the difficulty of repair differs greatly, and counterdie is easy to processing, and patrix is processing difficulties then.This situation disassembles the upper table of patrix from hydraulic press often, carries out repair processing again, and then reinstalls.This method wastes time and energy very inconvenient, and mould repair working (machining) efficiency is low.

Summary of the invention

The utility model provides a kind of mould repair processing hydraulic press upset comparatively easily workbench for solving the technical problem that exists in the known technology.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

A kind of hydraulic press upset workbench, by the slide block that moves up and down along hydraulic press two heel posts, be installed in the upper table of slide block lower plane, and the lower table corresponding with upper table formed, the front side edge of described slide block is equipped with four hinged seats that are hinged with the upper table back side edge, upper table rear side two ends are equipped with roller, also be fixed with the supporting base of four band pin-and-holes on the upper table back side edge, the back side edge of slide block is equipped with four holders that have with the corresponding pin-and-hole of supporting base pin-and-hole, in the pin-and-hole of holder and supporting base bearing pin is installed, each bearing pin outer end is equipped with the locked cylinder that drives the bearing pin move left and right; Pass through two hinged two overturning oil cylinders that drive working platform overturnings side by side of rotating shaft in the slide block, the collar that has two lugs is installed on overturning oil cylinder top, fixed head also is installed in the slide block, extension spring and inclination limited block that overturning oil cylinder is tilted are installed between fixed head and the lug, the tailpiece of the piston rod of two overturning oil cylinder lower ends is equipped with suspension hook, the side of overturning oil cylinder is movably installed with the gag lever post that moves up and down with suspension hook, and two hangers that flexibly connect with two suspension hooks are installed at the upper table back side; On lower table, also be equipped with and corresponding two closed slides of upper table two rollers.

The utility model can also adopt following technical measures:

The upper end of described two overturning oil cylinders also is equipped with balancing weight.

Advantage and the good effect that the utlity model has are: drive the overturning oil cylinder of upper tables upset and be installed in closed slide on the lower table owing to be equipped with two in holder that the slide block installed in front has the rear side of the hinged seat that makes upper table upset, slide block to be equipped with upper table is resetted, slide block, make upper table can realize upset, reduced the difficulty of mould repair greatly, improved operating efficiency, the utility model also has advantage simple in structure, that be easy to make in addition.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1, front side edge is fixed with four hinged seats 13 below the slide block 15 of hydraulic press, on hinged seat, be hinged with turnover upper table 8 by rotating shaft 9, the back side edge of upper table is shaped on the supporting base 18 and two side wheels 11 of four band pin-and-holes, as shown in Figure 2, be fixed with four holders that have pin-and-hole 12 that combine with the upper table supporting base on slide block lower backside limit, bearing pin 20 is installed in the pin-and-hole of each supporting base and holder, also is equipped with four on slide block lower backside limit and drives the locked cylinder 19 that the locking bearing pin moves.In the centre of slide block by rotating shaft 14 hinged two overturning oil cylinders 1 that drive the upper table upset side by side, the tailpiece of the piston rod of two overturning oil cylinder lower ends is equipped with suspension hook 6, at the back side of the upper table of corresponding suspension hook the hanger 7 that flexibly connects with suspension hook is installed, the side of overturning oil cylinder also is equipped with the gag lever post 3 that moves up and down with suspension hook.For the hanger unhook of the suspension hook that prevents upper table when upset overturning oil cylinder with upper table, the collar 16 that has lug 17 is installed on overturning oil cylinder, fixed head 5 and limited block 4 are installed on slide block, between lug and fixed head, also be equipped with and make the extension spring 10 of overturning oil cylinder, balancing weight 2 also is installed in the upper end of overturning oil cylinder with the upper table inclination of upset.The roller 11 of corresponding upper table also is equipped with two closed slides 21 on the lower table 22 of hydraulic press, can upper table be turned fully like this, as shown in Figure 3.

Operating principle:

When upset upper table 8, drive locked cylinder 19 and open bearing pin 20, holder 12 and supporting base 18 are thrown off, it is descending to drive overturning oil cylinder 1, upper table begins turning, overturning oil cylinder tilts gradually with the flip angle of upper table till spacing, it is descending slowly to drive slider of hydraulic press 15 then, two side wheels 11 of upper table are rolled on the closed slide on the lower table 22 21, continue upset, when the upper table slide block stop motion about 180 ° time of overturning, the upper table upset is finished;

When upper table resets, it is up slowly to drive slider of hydraulic press, upper table begins revolution, up to the hanger of upper table with after suspension hook is connected, slide block stops, drive the overturning oil cylinder backhaul upper table is resetted, the upper table rear drive locked cylinder translation that resets is inserted in the pin-and-hole of holder and supporting base bearing pin simultaneously, and upper table resets and finishes.
