Description of drawings: Fig. 1 is an overall structure schematic diagram of the present invention, and Fig. 2 is the stress schematic diagram of punch 12 and die 5.
The specific embodiment one: the (see figure 1) present embodiment is made up of die holder 1, fore-set 2, spring 3, gasket ring 4, die 5, drift guide pin bushing 6, drift 8, spacing ring 9, punch 12, heating tube 14, knock-pin 16; The center of die holder 1 has up big and down small step through hole 17, the bottom of step through hole 17 is push rod chamber 17-1, knock-pin 16 is located in the push rod chamber 17-1 of step through hole 17 bottoms, fore-set 2 is arranged in the working chamber 17-2 on step through hole 17 tops, the upper end of the lower end of inverse-T-shaped fore-set 2 and knock-pin 16 flexibly connects, spring 3 is located between the inwall of interior fore-set 2 of working chamber 17-2 and working chamber 17-2, gasket ring 4 is located at the top of working chamber 17-2 inner spring 3, die 5 is located at the top of interior gasket ring 4 of working chamber 17-2 and fore-set 2, the lower end of drift guide pin bushing 6 is located in the top of working chamber 17-2, the upper end of drift guide pin bushing 6 is fixed on the upper surface of die holder 1 by its umbrella along 6-1, the lower end of drift 8 is located in the drift guide pin bushing 6, drift 8 is provided with spacing ring 9, punch 12 is located at the interior upper end that reaches fore-set 2 of shape chamber 5-1 at die 5 centers, have at least one blind hole 18 in the die holder 1, be fixed with heating tube 14 in the blind hole 18, have annular wiring groove 10 on the die holder 1 on blind hole 18 tops.
The specific embodiment two: the difference of the (see figure 1) present embodiment and the specific embodiment one is, has annular space 19 in the outer wall inboard of die holder 1, is provided with heating collar 13 in annular space 19.Other composition is identical with the specific embodiment one with annexation.
The specific embodiment three: the difference of the (see figure 1) present embodiment and the specific embodiment one is, the umbrella of drift guide pin bushing 6 is along having through hole 6-2 on the 6-1, with umbrella along having screwed hole 1-1 on the corresponding die holder 1 of the through hole 6-2 on the 6-1, umbrella is along being provided with dormant bolt 7 in through hole 6-2 on the 6-1 and the screwed hole 1-1.Other composition is identical with the specific embodiment one with annexation.
The specific embodiment four: the difference of the (see figure 1) present embodiment and the specific embodiment one is, has the screwed hole 15 that connects usefulness in the bottom of die holder 1.Other composition is identical with the specific embodiment one with annexation.
The specific embodiment five: the difference of the (see figure 1) present embodiment and the specific embodiment one is, radially has a thermometer hole 20 at die holder 1 upper edge die holder 1.Other composition is identical with the specific embodiment one with annexation.
The course of work: at first utilize the screwed hole 15 of die holder 1 bottom that die holder 1 is fixed on the former, then fore-set 2, spring 3, gasket ring 4, die 5 are placed in the working chamber 17-2 of die holder 1 by order from down to up, again punch 12 is installed in the shape chamber 5-1 of die 5, again blank 11 is placed on the upper end of the punch 12 in the shape chamber 5-1 of die 5, with dormant bolt 7 drift guide pin bushing 6 is fixed on the die holder 1 then, spacing ring 9 is placed on the drift guide pin bushing 6, drift 8 is placed in the concentric holes of spacing ring 9 and drift guide pin bushing 6 subsequently.Finish the assembling of mould and carry out the heating of mould and blank afterwards, can select heating tube 14 or heating collar 13 to heat separately, it is heated simultaneously.The electroheat pair of measuring temperature can reach the inside of die device by the thermometer hole on the die holder 1 20, so that the forming temperature of accurate Measurement die and blank.After reaching forming temperature, the force application mechanism of former is pressed onto on the drift 8, and drift 8 is pressed onto on blank 11 and the die 5 simultaneously.Die 5 is arranged on the gasket ring 4, and gasket ring 4 is supported by spring 3, and die 5 is passed to spring 3 with power by gasket ring 4, and spring 3 shrinks under pressure, thereby die 5 moves downward.The direction of motion of gasket ring 4 is guaranteed by the working chamber 17-2 and the fore-set 2 of die holder 1.The direction of motion of die 5 is guaranteed by the working chamber 17-2 of die holder 1, and blank 11 is passed to punch 12 with power, yet punch 12 is placed on fore-set 2 upper surfaces, can not move.The effect that blank 11 is stressed begins to take place plastic deformation after reaching certain value, shape chamber 5-1 that can filling die 5, and part with the same shape and size in die shape chamber is shaped.The deflection of blank is controlled by spacing ring 9, and the spacing ring 9 of selection different-thickness is controlled the drafts of drift 8, reaches the purpose of control blank 11 deflections.This spacing ring can be controlled the drafts of drift 8, thereby also can protect die 5 and punch 12 below the drift 8, in order to avoid damaged by pressure.Take away drift 8 after being shaped, promote knock-pin 16 and make its rising, knock-pin 16 promotes fore-set 2 and punch 12, and the miniature parts that is shaped is ejected die 5.Finished whole forming process.
This die device can use on baby press, also can use on Material Testing Machine, has excellent adaptability.Control accuracy to forcing press is less demanding, and forming process is controlled by the die device structure fully.The precision of drip molding is guaranteed by punch 12 and die 5.Die 5 and punch 12 adopt the high accuracy process technology to process, and quality of fit is very high, and the gap has only several microns.Punch 12 is led by die 5, and punch 12 is placed on fore-set 2 upper surfaces, is unfixed, and die 5 can move among a small circle when eccentric in a small amount having like this, to adapt to the motion of die 5.And the working chamber 17-2 of other part of die device such as gasket ring 4, die 5 and die holder 1 does not then need too high quality of fit between drift 8 and the drift guide pin bushing 6.Change frictional resistance is positive frictional force, helps the shape chamber of blank 11 filling dies 5.As shown in Figure 2, die 5 can freely move downward, and punch 12 is fixed.Between blank 11 and die 5, produce frictional force, the direction of motion of the direction of this frictional force and die 5 is consistent, blank 11 can better carry out filling to the shape chamber of die 5 under the effect of this frictional force, the frictional force with raw material becomes the positive frictional force that helps being shaped like this.Because die 5 freely-movable downwards, the power that drift 8 applies all is added on the blank 11, that is to say that the load that former provides all is added on the blank 11; improved the efficient of equipment; energy savings reduces cost, and has also protected minisize mould simultaneously effectively.
