Abstract
The present invention relates to a non-mold multi-point shaping device for plates, particularly to a device for processing plates in a plastic way, which belongs to the field of mechanical engineering. The present invention is composed of an upper and a lower fundamental body control unit groups, an adjusting mechanism, a load mechanism and a frame. The present invention is characterized in that the upper and the lower fundamental body groups are composed of a plurality of fundamental bodies which can be adjusted and edge pressing devices, wherein the fundamental bodies are adjusted by the adjusting mechanism to freely move along an axial direction, and can be positioned at any position; the edge pressing devices are arranged at the peripheries of the upper and the lower fundamental body control unit groups. The edge pressing devices adopt a plurality of hydraulic cylinders which can simultaneously press edges for edge pressing rings.
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, by be connected four on the cylinder lower and upper cross-member, moved cross beam, element body control module group, load maintainer are formed up and down, around element body control module group up and down, also be provided with flange fixing installation up and down, up and down flange fixing installation and up and down element body control module group be fixed on moved cross beam and the sill by big plate respectively, described flange fixing installation can adopt a plurality of hydraulic cylinders, or nitrogen spring or helical spring composition, flange fixing installation can be exerted pressure to the blank holder between flange fixing installation about being located at simultaneously.
Said blank holder adopts the flexibility or rigidity blank holder.

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 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; Element body control module group and the flange fixing installation arranged around the element body control module group are separately fixed on two blocks of big plates together up and down, last element body control module group and big plate are fixed on the moved cross beam 6 and move up and down with moved cross beam 6, and following element body control module group and big plate are fixed on the sill together.During shaping, last element body control module group and flange fixing installation move down with moved cross beam 6, with the following element body control module 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, just around the element body control module group of shaping usefulness, add before being shaped the flange fixing installation that to exert pressure to sheet material, 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 the blank holder between flange fixing installation about being located at 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.
