Description
Technical field
The present invention relates to the shaping process equipment of large-scale three dimensional curved surface plate members, be specifically related to a multiple pressure sheet material forming device, for example have the element body of shaping process equipment, a particularly multiple pressure sheet material forming device of the ship hull plate of arbitrary surface shape.
Background technology
Need the plate members of unitary mould press forming for some, the now existing Mould Machining of using a multiple pressure sheet material forming device to substitute costliness, for example the multiple spot sheet material forming forcing press that goes out of domestic-developed etc.An existing multiple pressure sheet material forming device comprises: movably upper frame, a plurality of a plurality of times element bodies of going up element bodies, underframe, being connected with underframe of being connected with upper frame; Each element body comprises pillar, pressure head, and pillar is connected with framework, and pressure head is connected with pillar.
An existing multiple pressure sheet material forming device element body, its pressure head working face divides convex surface and plane.
The pressure head working face is a multiple pressure sheet material forming device of convex surface, also claims multiple spot sheet material forming device, and the deficiency of its element body is: because its pressure head mould is a convex shape, when mould and plate carry out press forming, pressure head and plate are to contact, and be subjected to concentrated force this moment, makes plate produce impression easily; In addition when processing curve sheet material, when some position of sheet material tilts greatly (as shown in Figure 9), because the pressure head working face is a convex shape, the contact point of last element body pressure head 6 and sheet material 18 and the contact point of following element body pressure head 6 and sheet material 18 be not on same location point, make sheet material 18 produce local concavo-convex impression distortion easily, so be difficult to satisfy large-scale ship hull plate fairing and the little shipbuilding quality requirement of impression.
The pressure head working face is the plane element body, as 141 pages of disclosed element bodies of Fig. 3-61 of " technology of hull construction " (People's Transportation Press 1980 December the 1st edition), as shown in figure 10, pressure head 6 working faces of this element body are the plane, and pressure head 6 is connected with the spherical bar supporting seat of pillar 8 one ends with the spill ball-and-socket of pillar 8 by the pressure head bottom surface.The deficiency of this element body is: 1, owing to the center of gravity height, pressure head easily plays pendulum, that is: pressure head always is in heeling condition easily; 2, the height at pressure head center has bigger variation when tilting during bent plate, makes that to regulate control complicated, brings inconvenience.
Summary of the invention
Technical problem to be solved by this invention is: the active hemispheric pressure head element body of a kind of multiple pressure sheet material forming device is provided, is difficult for tilting when the pressure head of this element body is worked, the face fairing of sheet material plate and the impression of extrusion are little.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:

In the such scheme, be provided with spring between pressure head and the pillar, the sphere of pressure head is pressed on the spill spherical support seat by spring.
In the such scheme, element body also comprises studdle, is used to drive the actuating unit that studdle rotates for following element body, following element body; Pillar is a Hollow Pillar; The lower end of pillar is fixed with the holding nut that cooperates with studdle, and studdle passes holding nut and inserts Hollow Pillar; The bottom surface of studdle and underframe is rotationally connected; Spill spherical support seat is arranged on the pillar upper end.
In the such scheme, be provided with displacement transducer between pillar and the studdle.
In the such scheme, spring is extension spring, and the two ends of spring are connected with pressure head, pillar respectively.
In the such scheme, spring is a stage clip; Also be provided with connecting rod, baffle plate with holes between pressure head and the pillar; Baffle plate with holes is fixedlyed connected with pillar (8); One end of connecting rod is connected with pressure head, and the other end passes baffle plate with holes; Spring is arranged on baffle plate with holes and passes between the connecting rod of baffle part with holes.
In the such scheme, displacement transducer is the mangneto displacement transducer, and this sensor comprises magnetic induction expansion link and magnet ring, and the magnetic induction expansion link is fixedlyed connected with the lower end of pillar, and magnet ring is fixedlyed connected with studdle, and the magnetic induction expansion link passes from the center of magnet ring.
In the such scheme, studdle is a cored screw, and magnet ring is arranged on the top of studdle, and the part of magnetic induction expansion link is inserted in the hollow studdle.
The present invention compares with multiple spot mould in the past, and its advantage is:
1, sheet material is not a contact when compacting is crooked, but pressure face contact uniformly, so the impression of sheet material is significantly alleviated;
2, no matter active hemispheric pressure head with what inclination of do of sheet material rotates, the hemisphere centre of sphere of last element body is all corresponding constant on same vertical line with the following element body hemisphere centre of sphere, even when bent plate, can not make the centre of sphere of pressure head produce the changing of the relative positions, can not produce local concavo-convex impression distortion naturally as multi-point forming yet yet;
3, when the heeling condition of carrying out the sheet material processing curve was adjusted, the centre of sphere height of active hemispheric pressure head can not change yet, and helps calculating, setting and the adjustment of element body height;
4, always in supporting surface, in addition, the sphere of pressure head is pressed on the pillar by spring the center of gravity of active hemispheric pressure head, makes pressure head be in stable state all the time, can not tilt arbitrarily, and be convenient to operation.
