It can also be seen that from Fig. 1, Fig. 2, support between element body 5 and adjusting bolt 4 and be threaded connection and transmitted load, adjust its height by the rotation of adjusting bolt 4, thus adjust the stroke of each element body unit, the enveloping surface that the end supporting element body 5 is formed is target shape face shape.
It can also be seen that from Fig. 1, Fig. 2, sheet material 9 is clamped between seaming chuck 10 and push-down head 3, the pressure driving hydraulic cylinder 1 to be applied to driver element is applied to the pressure of shape adjusting unit higher than supporting cylinder 6, descending active role of driver element, and then promote push-down head 3 and adjusting bolt 4 and move downward, the hydraulic circuit 123 of liquid in supporting cylinder 6 through bottom and hydraulic joint 125 are discharged by the proportioning valve of hydraulic system, pressure in supporting cylinder 6 makes all adjusting bolts 4 produce thrust upwards, forms the Normal Constraint to sheet material 9.
As can be seen from Figure 3, described mould bases 12 is provided with guide plate 128 and lower guide plate 127, upper guide plate 128 is arranged on the top board 121 of mould bases, and lower guide plate 127 is arranged on the base plate 124 of mould bases, and on upper guide plate and lower guide plate, each piston corresponding is provided with pilot hole 126.For the operation of piston provides guiding.Piston can move up and down along the axis of pilot hole.A hydraulic circuit 129,123 is also provided with in the top board 121 of described mould bases 12 and base plate 124, and the hydraulic joint 1210,125 of correspondence.The oilhole of hydraulic cylinder 1 or supporting cylinder 6 is driven to be connected with the hydraulic circuit 129 on top or the hydraulic circuit 123 of bottom respectively.Hydraulic cylinder is driven to be connected with hydraulic control system respectively by hydraulic circuit with supporting cylinder.
Described seaming chuck 10 and push-down head 3 are hemi-spherical indenter, driving element body 11 and adjusting bolt 4 are respectively equipped with hemispherical groove, multiple permanent magnet 32 is had at groove internal fixtion, rely on magnetic force upper pressure 10 and push-down head 3 to be attracted in hemispherical groove, and freely rotate around the centre of sphere and swing.As shown in Figure 4, Figure 5.Specifically be described below for push-down head: the base that described push-down head 3 relies on the magnetic force of magnet 32 and adjusting bolt 4 to be provided with is connected, freely can rotate around the centre of sphere of push-down head 3.In forming process, push-down head 3 can rotate along with the distortion of sheet material 9, remains the plane contact with sheet material 9, adds push-down head 3 and the contact area of sheet material 9, avoids impression and wrinkling generation.For the push-down head 3 be arranged in adjusting bolt 4, hemispherical groove center in adjusting bolt 4 offers hexagon adjusting hole 33, hemispherical push-down head 3 has center hole 31, use die nut to be inserted in hexagon adjusting hole 33 by this circular hole and adjusting bolt 4 is adjusted.
For adapting to different sheet material parameters and curve form, the division numbers of element body driver element and arrangement mode can design as required, adjust, change.In addition, the discharge opeing pressure of the Stress control supporting cylinder 6 that can also set according to the thickness of shaped sheet and material property resize ratio valve, and then control push-down head support unit to the Normal Constraint power of sheet material 9, the principle of hydraulic control system is as shown in Figure 6.Hydraulic control system belongs to prior art, repeats no more.
The course of work of the present invention is: first according to the position of intending profile surface Adjusting Shape adjusting bolt 4, the enveloping surface that push-down head 3 is formed is target surface, then sheet material 9 is placed into the upper surface of push-down head 3; In supporting cylinder 6, be filled with liquid, make piston 8 promote push-down head 3 up, sheet material 9 is clamped between push-down head 3 and seaming chuck 10; Liquid is filled with to driving hydraulic cylinder 1, the pressure that the pressure that driving hydraulic cylinder 1 is provided provides higher than supporting cylinder 6, under the effect of pressure differential, piston 2 promotes the descending pressed sheet 9 of seaming chuck 10, and force push-down head 3 and adjusting bolt 4 descending, the hydraulic circuit 123 of liquid in supporting cylinder 6 through bottom and hydraulic joint 125 are discharged by the proportioning valve of hydraulic control system again, sheet deformation order depends on the deformation extent in each region completely, the area preference distortion the most easily deformed, by that analogy, the progressive molding to blank is realized.Now, the clamping that the crushed element of sheet material 9 and non-crushed element are all in element body driver element and support unit is about intrafascicular, and this restraining force depends on the fluid pressure in supporting cylinder 6, i.e. the pressure of proportioning valve setting; Descending along with driving hydraulic cylinder 1 progressively to promote seaming chuck 10, the deformed region of sheet material 9 progressively increases, when all support element bodies are forced into bottom dead centre, the upper surface of push-down head 3 is combined into the final shaping form of curved surface, under the acting in conjunction of seaming chuck 10, sheet material 9 distortion becomes the final shape of product needed.After shaping terminates, drive hydraulic cylinder 1 and supporting cylinder 6 discharge opeing, seaming chuck 10 moves upward under the drive of spring 13, and adjusting bolt 4 and push-down head 3 fall under spring 7 and Action of Gravity Field, takes out the sheet material forming part suppressed.
Mould bases of the present invention can complete independently Multi-point Forming Process, adjusts the position of each adjusting bolt 4 according to the curve form intending being shaped, and drives presser unit and adjusts shape support unit all to be exerted pressure by hydraulic control.
The present invention adopts above-mentioned composition structure, provides Normal Constraint in forming process without the need to flange fixing installation; All the time there is stable, uniform normal pressure to act on sheet material in forming process, can effectively suppress sheet material wrinkling; Mould bases this as load-bearing frame and self is equipped with hydraulic system, without the need to using the chargers such as forcing press to exert pressure during shaping, can complete independently sheet material forming; Pressure in the hydraulic cylinder of sheet material both sides can control respectively, thus can carry out step-less adjustment to driving the pressure differential of hydraulic cylinder and supporting cylinder, under the condition ensureing sheet material clamping and distortion, with minimum pressure forming, avoids unnecessary energy loss; In sheet deformation process, main stretching strain direction is constant and strain rate is constant, can deform at the position be the most easily shaped, forming path meets minimum plastic work principle, and therefore drip molding Strain Distribution is very even, substantially increase For The Forming Limit of Sheet Metals, surface quality is guaranteed; In forming process, each element body all according to stress condition real time kinematics, therefore can may realize flexible forming to the full extent.
