Abstract
The plate material mould-free multipoint forming equipment is formed from upper and lower basic body control unit groups, regulating mechanism, loading mechanism and machine frame, and is characterized by that said upper and lower basic body groups are respectively formed from several adjustable basic bodies and edge-pressing devices, its basic body can be regulated by regulating mechanism and can be freely moved along its axial direction, and can be positioned at any position. The edge-pressing device is mounted on the periphery of every upper and lower basic body control unit group, and said edge-pressing device can be controlled and operated by several hydraulic cylinders.
Description
Technical field
Non-mould multi-point shaping apparatus for plates is the equipment that sheet material is carried out plastic working, belongs to mechanical engineering field.
Background technology
At present, sheet material forming mainly adopts various forcing presses to realize by mould.Each parts all needs a cover or number mold just can finish forming process.Traditional sheet material forming plant automation degree is lower, and its efficient and crudy and precision can't satisfy the needs that modern industry is produced.Non-mould multi-point shaping apparatus for plates is to adopt computer-controlled advanced sheet material forming equipment.Utilize a plurality of regularly arranged, adjustable for height element body (drift) and arbitrarily change the forming face shape, replace traditional mould and realize the multi-point forming of plate accessory, be radical reform and innovation, will produce tremendous influence the technological progress of China's machinery manufacturing industry to existing plate accessory former.
Summary of the invention
The objective of the invention is to change traditional mould that utilizes and make the processing mode of sheet material forming, a kind of multi-point formation apparatus for sheet material that has the flanging function based on the non-mould multi-point forming technology of control automatically of realizing is provided.
Above-mentioned purpose of the present invention is achieved in that accompanying drawings is as follows.
Non-mould multi-point shaping apparatus for plates is by element body control module group up and down, guiding mechanism, load maintainer and frame are formed, the element body group is made up of a plurality of adjustable element bodies and flange fixing installation up and down, element body can axially be moved freely along it by the guiding mechanism adjustment, and can locate at an arbitrary position, and flange fixing installation is contained in element body control module group's periphery up and down, flange fixing installation adopts a plurality of hydraulic cylinders, and these hydraulic cylinders can apply flanging to blank holder simultaneously.
Said flange fixing installation can adopt nitrogen cylinder or elastomeric material.
Said blank holder adopts the flexibility or rigidity blank holder.
Description of drawings
Further specify the particular content of the present invention and the course of work thereof below in conjunction with the accompanying drawing illustrated embodiment.
Fig. 1 is the structural representation with non-mould multi-point shaping apparatus for plates of four-column type frame;

The specific embodiment
Further specify the particular content of the present invention and the course of work thereof below in conjunction with the accompanying drawing illustrated embodiment.
Consult Fig. 1: non-mould multi-point shaping apparatus for plates, by comprising the control module of the element body up and down group who forms by following element body control module group 1 and last element body control module group 4, comprise the flange fixing installation of forming by down flanging cylinder group 2 and last flanging cylinder group 5 up and down, and load maintainer 6,7 and blank holder 9,10 up and down.It is to be connected together by four cylinders by lower and upper cross-member that sheet material does not have mould multiple spot shaped device, and moved cross beam 6 slides on four cylinders between the lower and upper cross-member, and four cylinders play the guiding role; Fundamental group and the flange fixing installation arranged around the element body are separately fixed on two blocks of big plates together up and down, and last element body group and big plate are fixed on the moved cross beam 6 and move up and down with moved cross beam 6, following element body group and greatly plate be fixed on the sill together.During shaping, last element body group and flange fixing installation move down with moved cross beam 6, with the following element body group who is fixed on the sill pressure are made part forming.
In order to prevent that defectives such as wrinkling from appearring in sheet material in forming process, around the element body of shaping usefulness, add the flange fixing installation that just can exert pressure to sheet material before some are shaped, this device can be made up of a plurality of up and down hydraulic cylinders or nitrogen spring or elastomeric material (as helical spring), its pressure-pad-force to the non-uniform Distribution that blank holder applies simultaneously can be realized step-less adjustment, and blank holder can adopt rigidity or flexible structure.Adopt the action principle of hydraulic cylinder (or nitrogen spring) to consult Fig. 2,3, arrangement is consulted Fig. 4.Realize rigid blank holder (consulting Fig. 3) or flexible flanging (consulting Fig. 2) by the structure that changes blank holder.By the adjusting of hydraulic control system (or nitrogen pressure control system) pressure, realize stepless control to blank holder pressure.
For the shape that adapts to different plate material parts and the needs of forming mode, element body control module group number can change up and down, and flanging cylinder number also can change.
Claims (3)
1. non-mould multi-point shaping apparatus for plates is by element body control module group up and down, guiding mechanism, load maintainer and frame are formed, it is characterized in that the element body group is made up of a plurality of adjustable element bodies and flange fixing installation up and down, element body can axially be moved freely along it by the guiding mechanism adjustment, and can locate at an arbitrary position, and flange fixing installation is contained in element body control module group's periphery up and down, flange fixing installation adopts a plurality of hydraulic cylinders, and these hydraulic cylinders can apply flanging to blank holder simultaneously.
