Abstract
A half-mould shaping technology for metallic plate features that the solid particles are used to replace the rigid male mould. It includes such steps as providing high-hardness steel balls with diameter less than 4 mm or natural sand as force transfer medium, making a female mould, loading a metallic plate in it, adding said force transfer medium on the plate, and using a pressing head to press them for the plastic deformation of metallic plate.
Description
Technical field
The present invention relates to the sheet moulding technical field, particularly relate to a kind of half-mould forming process for metal plate material.
Background technology
Conventional rigid punch-die deep-drawing technique needs repeatedly drawing and forming to the deep drawing part forming of big pull and stretch ratio, and forming quality is relatively poor.For the pull and stretch of inductile, large deformation part even can't be shaped.For this reason, people have proposed half-module shaping technique (also claiming the plate flexible die forming).
It is to utilize certain power transmission medium as punch (or die) that the plate half module is shaped, and uses a rigidity die (or punch) again, under the pressure effect of transmission medium, makes the technology of plate by the shape shaping of rigid die.
In the plate half-module shaping technique, it is the liquid state shaping of power transmission medium that the half module of cold conditions is formed with water or oil, be shaped with the half module of cohesive material as the power transmission medium, the half module that with the elastomer rubber is the power transmission medium is shaped, and is shaped as the expansive forming of power transmission medium and explosive forming and with the glass of the molten condition hot half module as the power transmission medium with gas.The appearance of these technologies has promoted the development of sheet forming technology, is that the half module of power transmission medium is shaped the most representative with oil or water (emulsion) particularly.
With oil or water (emulsion) is the half module shaping of power transmission medium, is characterized in that pressure distribution is even.Yet equally distributed pressure also is unfavorable for the control of drip molding thickness, in case local attenuation appears in the somewhere material in the forming process, will very easily produce in weakened section and break.In addition, hydroforming process flows material and is restricted because sealing control difficulty must be used the sealing ring forced seal, causes plate to be out of shape by attenuation, and this has just restricted the performance of the sheet material forming limit greatly.In this case, for the qualified products that are shaped often need to increase sheet metal thickness, material weight is improved.In addition, because the sealing difficulty, it is difficult that easily control is leaked and leaked in generation, often causes the shaping failure.When being shaped failure, fluid splashes, and contaminated environment jeopardizes the operator.Therefore, the application of shaped by fluid pressure is restricted.
Is that resisting medium has not only overcome rubber and can easily not realize pressure control and be difficult to characteristics to the part Accurate Shaping with cohesive material as the half module shaping main technological features of power transmission medium, has remedied liquid-filling shaping polluted and be difficult to keep long-time excellent sealing to production defective again.But also exist because resisting medium still needs the better seal environment, need control system, resisting medium and the high deficiency of mold system cost of more complicated.
Summary of the invention
In order to overcome the prior art above shortcomings, the invention provides a kind of half-mould forming process for metal plate material, the present invention has the advantage of Hydroform process, and for the need deep drawing part forming of the big pull and stretch ratio of pull and stretch repeatedly, this technology can once-forming.The deep drawing part forming method of complex-shaped for solving, the big pull and stretch ratio of this invention provides a new effective way.
This metal blank half module shaping forming technology adopts the power transmission effect of solid particle transmission medium 5 that plate 4 is carried out the half module shaping, and its processing step is:
A. make the die cavity and the pressure head 7 of die 1 according to the part to be processed outer shape, the parameter of pressure head 7 is: the cone angle of pressure head 7: 30 °≤α≤180 °; Cooperate between pressure head 7 and the tube for feed 6 and belong to matched in clearance, its diameter is than the little 1-5mm of diameter of work piece;
B. plate 4 is placed between blank holder 3 and the following blank holder 2, and is full of solid particle transmission medium 5 in tube for feed 6; By forcing press last blank holder 3 is applied a pressure F, compress plate 4, prevent that plate is wrinkling;
C. by forcing press pressure head 7 is applied a pressure P, make solid particle transmission medium 5 produce forming pressures, plate 4 produces plastic deformation under the forming pressure effect of solid particle transmission medium 5, when plate 4 distortion fully and die when being close to, shaping finishes.
Solid particle transmission medium 5 is natural sand or high rigidity steel ball, the diameter phi≤4mm of high rigidity steel ball, hardness HRC 〉=50.
The present invention has adopted solid particle to replace the effect of rigidity punch (or elastomer, liquid) that plate is carried out half module to be shaped.Because solid particle has some characteristic of liquid, as has an approximate Incoercibility of good flowability and volume, therefore this technology has the advantage of Hydroform process, has overcome hydroforming sealing difficulty, has needed the special hydraulic system of a cover, the shortcoming that die cost is high.With regard to conventional rigid punch-die deep-drawing technique, need repeatedly pull and stretch for the deep drawing part forming of big pull and stretch ratio, and this new technology can once-forming.The deep drawing part forming of complex-shaped for solving, the big pull and stretch ratio of the proposition of this new technology provides an effective way.
The present invention has overcome hydroforming and has sealed shortcoming difficult, oil contamination, and a kind of deep drawing technology of suitable metal blank once-forming is provided.Have the part forming quality is good, mould structure is simple, die cost is low, energy resource consumption is low, be beneficial to environmental protection sheet forming technology and mould thereof.
The invention has the beneficial effects as follows, just can reach the purpose of control material attenuation by regulating pressure distribution, thereby can improve the forming property of the sheet material forming limit and raising sheet material the mobile achieve effective control of material in being shaped.Sheet material forming for the deep drawing part can replace repeatedly pull and stretch of traditional punch-die, realizes once-forming.In solid particle medium half module forming process, do not need sealing.Can be used for the simple or complex parts that production surface quality, required precision are higher, be difficult to be out of shape.
Description of drawings
Fig. 1 is a view before this New Forming Process is shaped;
Fig. 2 is a view after this New Forming Process is shaped.
In Fig. 1, Fig. 2, in 1. dies, 2. descend blank holder, 3. go up blank holder 4. plates, 5. solid particle transmission medium, 6. tube for feed, 7. pressure head.
The specific embodiment
Fig. 1 is the shaping dies preparatory stage, in this stage, makes the die cavity of die 1 according to the part to be processed outer shape.The parameter of pressure head 7 is: cooperate between the cone angle of pressure head 7: α=70 °, pressure head 7 and tube for feed 6 to belong to matched in clearance, the diameter of pressure head 7 is than the little 2mm of diameter of work piece.The solid particle transmission medium 5 that adopts is natural sand.Plate 4 is placed between blank holder 3 and the following blank holder 2, and in tube for feed 6, be full of solid particle transmission medium 5, by forcing press last trim ring 3 is applied a pressure F, compress plate 4, prevent that plate is wrinkling,, make solid particle transmission medium 5 produce forming pressure then to pressure head 7 being applied a pressure P by forcing press, plate 4 produces plastic deformation under the forming pressure effect of solid particle transmission medium 5.When plate 4 distortion fully and die when being close to, shaping finishes, and enters the final shaping stage of Fig. 2.
