Description
Technical field
The utility model belongs to the hydraulic machinery technical field, particularly a kind of device that utilizes the single action hydraulic press liftout tank to realize double-action drawing.
Background technology
Plate under the effect of surperficial tangential stress, often is easy to generate unstability and forms wrinklingly when carrying out deep drawing, and solving wrinkling effective method is that plate is carried out rational flanging.Generally on single action hydraulic press, can't realize two dynamic pressure limits, some adopts the method that increases by a cover flanging cylinder to realize flanging, and this structure not only will increase the flanging cylinder, but also needs corresponding hydraulic pressure of increase and electrical control to realize, cause complex structure, the cost height.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, reaches the function that can realize two dynamic pressure limits on single action hydraulic press, so that a kind of device of realization double-action drawing simple in structure, with low cost to be provided.
For achieving the above object, technical solution of the present utility model is: a kind of device that utilizes the single action hydraulic press liftout tank to realize double-action drawing, by the liftout tank that is arranged in the hydraulic press sill, the support case of opening before and after being arranged on the sill, be fixedly mounted on the punch that supports on the case, top links to each other with the hydraulic press moved cross beam, the bottom contacts the compositions such as die that can move up and down with moved cross beam with the plate upper surface, it is characterized in that: liftout tank piston rod and supporting plate bottom flexibly connect, supporting plate top flexibly connects with the thimble rod that can slide in supporting the upper box part pilot hole, and thimble rod top flexibly connects with the bottom of the blank holder of middle band punch pilot hole.
Described liftout tank cavity of resorption is provided with control valve, and the pressure-pad-force that blank holder produces can be regulated by control valve.
The beneficial effects of the utility model are: owing to directly utilize the liftout tank of common single action hydraulic press and hydraulic pressure, electric control loop, do not need special flanging cylinder, flanging crossbeam and special hydraulic pressure, electric control loop, realized realizing the function on two dynamic pressure limits at single action hydraulic pressure, the structure of hydraulic press is simplified greatly, cost significantly reduces, and has obtained good economic benefit and social benefit.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a work schematic diagram of the present utility model;
Among the figure: the 1-liftout tank, 2-supports case, 3-punch, 4-thimble rod, 5-supporting plate, 6-blank holder, 7-die, 8-sill, 9-entablature, 10-control valve, 11-liftout tank piston rod, 12-plate.
The specific embodiment
Now in conjunction with the accompanying drawings the specific embodiment of the present utility model is described in further details.
Referring to accompanying drawing 1-2, of the present utility model by the liftout tank 1 that is arranged in the hydraulic press sill 8, the support case of opening before and after being arranged on the sill 82, be fixedly mounted on the punch 3 that supports on the case 2, top links to each other with the hydraulic press moved cross beam, the bottom contacts die 7 compositions such as grade that can move up and down with moved cross beam with plate 12 upper surfaces, it is characterized in that: liftout tank piston rod 11 flexibly connects with supporting plate 5 bottoms, supporting plate 5 tops flexibly connect with the thimble rod 4 that can slide in supporting case 2 top pilot holes, and thimble rod 4 tops flexibly connect with the bottom of the blank holder 6 of middle band punch pilot hole.
Described liftout tank 1 cavity of resorption is provided with control valve 10, and the pressure-pad-force that blank holder 6 produces can be regulated by control valve 10.
The device that utilizes the single action hydraulic press liftout tank to realize double-action drawing of the present utility model is work like this, during work, liftout tank 1 ejects, liftout tank piston rod 11, drive supporting plate 5, supporting plate 5 drives thimble rod 4, thimble rod 4 drives blank holder 6, realize up, when blank holder 6 upper surfaces are concordant with punch 3 upper surfaces, eject and stop, put into the plate blank, moved cross beam is descending fast, descending at a slow speed, drive die 7 near workpiece, then, die 7 continues descending, realization is to the pull and stretch of plate, and at this moment, liftout tank 1 is at die 7, blank holder 6, thimble rod 4, the effect of supporting plate 5 realizes down returning, thereby realize the flanging of blank holder, prevent the generation of wrinkling inefficacy plate.
First as shown in Figure 2 ejecting by the liftout tank on the single action hydraulic press sill, the drive thimble rod is up, make the up and punch upper surface level of blank holder, ((a), (b))) subsequently, the descending realization flanging of the descending drive die of moved cross beam, ((c)), die continues the pull and stretch of descending realization band flanging, so simultaneously, liftout tank is return under the effect of die and blank holder, (d), (e), after reaching prescribed depth, the moved cross beam pressure release, backhaul, (f) (g) then, liftout tank ejects, and drives blank holder by thimble rod and realizes dnockout, (h) last liftout tank is return (i), finishes whole working cycles.
Here, the size of pressure-pad-force is to regulate by the control valve 10 of former liftout tank cavity of resorption.Thereby be implemented under the prerequisite that does not increase any hydraulic pressure and electric control system, on single action hydraulic press, realize the function on two dynamic pressure limits.
Though in conjunction with specific embodiments the utility model has been done detailed description; but it is evident that; this does not constitute any limitation this; those of ordinary skill in the art can replace all technical equivalents things and their combinations according to the knowledge of being grasped, and these all fall within the scope of the utility model protection.
