Abstract
A radial blocking flange fixing installation for combination of rigidity and flexibility, mainly solves the problem that flanging effect is undesirable in axialy symmetric part drawing process.Its technical scheme is that push rod active force is pressurizeed to power transmission medium by pressure plare, and pressure is passed to each radial blocking blank holder by power transmission medium.Power transmission medium pro rata distributes different pressure-pad-forces to each blank holder that contact area does not wait, and each blank holder can fully contact with plate and apply pressure-pad-force to plate.Which solves the contact problems of plate and die, improve the drawing and forming quality of axialy symmetric part, promote the further research of plate radial blocking deep-drawing technique.
Description
Art
The utility model relates to sheet material forming field, specifically be axialy symmetric part a kind of radial blocking flange fixing installation in Sheet drawing forming process.
Background technology
In process of sheet forming, when mould structure and size, machined material, forming speed, lubricating status, forming temperature etc. timing, pressure-pad-force is controllable unique technological parameter.Theoretically, in drawing process, in flange distortion district, the deformation state of each distortion particle is not identical with wrinkling trend, and required pressure-pad-force is also different, and constantly should change with drawing stroke.Therefore, desirable kiss gating-feeder device be apply different pressure-pad-forces to deformed area diverse location, and pressure-pad-force constantly should change with drawing stroke.
In sheet metal deep drawing process, during constant pressure for blank holding, part plate in flange can not contact with die, is in vacant state, and flanging effect is undesirable.When plate diameter increases, middle unsettled region also can increase, easier drawing unstability.Therefore, research is needed can to solve this problem with the flange fixing installation that plate fully contacts.
Summary of the invention
The utility model object is to provide a kind of new radial blocking flange fixing installation, solve the problem that in Sheet drawing process, flanging effect is undesirable, this radial blocking flange fixing installation can effectively prevent plate wrinkling, delay to break, thus improve the flanging effect of axialy symmetric part drawing and forming.
The technical scheme in the invention for solving the technical problem is: use the flexible force transmission media such as solid particle, liquid or high-elastic gonosome and rigid blank_holding ring compound to carry out the flange fixing installation of radial blocking, comprise blank holder, power transmission medium, push rod, taper matrix, pressure plare, sleeve and punch etc., pressure to the pressurization of power transmission medium, is dispensed to each radial blocking blank holder by power transmission medium by pressure plare by described push rod active force; Pro rata distribute different pressure-pad-forces to each blank holder that contact area does not wait, each blank holder fully can contact with plate and apply pressure-pad-force to plate; Punch passes through in the middle part of blank holder, not by the impact of flange fixing installation, does self-movement.
Compared with prior art, the utility model has following beneficial effect: 1. can solve the problem that in the drawing process of axialy symmetric part, flanging effect is undesirable, thus optimizes flanging effect further, improves the forming quality of axialy symmetric part; 2. the flexible force transmission medium such as solid particle, liquid or high-elastic gonosome has certain mobility, and volume is similar to incompressible, and bearing capacity is strong, cost is low; 3. be applicable to the radial blocking deep-drawing technique of various die (as plane die, curved surface die etc.), feasibility is high, and technique is advanced.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model device for carrying out said structure;
Fig. 2 is the A-A direction view of Fig. 1;
In figure: 1-fixed head, 2-screw, 3-sleeve, 4-pressure plare, 5-power transmission medium, 6-plate, 7-taper matrix, 8-blank holder one, 9-blank holder two, 10-blank holder three, 11-blank holder four, 12-punch, 13-push rod, 14-screw.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the radial blocking flange fixing installation concrete structure of this combination of rigidity and flexibility is: power transmission medium 5 seals by sleeve 3 and pressure plare 4, the upper surface of power transmission medium 5 and blank holder close contact at different levels, the plate 6 directly over each blank holder is in initial position with taper matrix 7.Each blank holder can relative motion in vertical direction, and punch 12 in the middle part of blank holder by the impact not by flange fixing installation, do self-movement.
In drawing process, push rod 13 active force is pressurizeed by pressure plare 4 pairs of power transmission media 5, and is passed on blank holder at different levels by pressure, makes blank holder at different levels to move and plate 6 close contact, plate 6 is pressed on taper matrix 7 on the surface.This device pro rata distributes different pressure-pad-forces by power transmission medium to each blank holder that contact area does not wait.Taper matrix 7 is descending, completes the drawing process of the radial blocking to plate 6.After drawing terminates, taper matrix 7 and push rod 13 are retracted into original state.
The utility model to the pressurization of power transmission medium by pressure plare, by pressure-pad-force pro-rata to blank holder at different levels, is achieved the radial blocking deep-drawing technique of axialy symmetric part, improves the forming quality of axialy symmetric part.
The utility model includes but not limited to present embodiment, and every principle is identical with mentality of designing and the utility model, or the simple substitute to the design, all falls within protection domain of the present utility model.
