Description
Technical field
The present invention relates to technical field of composite material manufacturing, especially the mold to the forming of multiple material tooling template and forming side
Method.
Background technique
Ideal composite molding tooling (hereinafter referred to as answering material tooling) feature should be high-precision, high rigidity, airtight
Property is good, thermal uniformity is good etc..The thermal uniformity of multiple material tooling is mainly that the thickness uniformity of template is leaned on to guarantee.It is how high
Effect, the accurate tooling template that shapes are the key that multiple material tooling manufacture and problem.
The method of template forming both at home and abroad has following several at present: thick steel plate overall processing method, pressurize dot welding method, rolling point by point
O ing method, die forming method.The shortcomings that thick steel plate overall processing method is: stock utilization is low, and processing charges is high, processing week
Phase is long.The shortcomings that point-by-point pressurization dot welding method is: forming accuracy is low, and forming stress is big.The shortcomings that roll forming method, is: only fitting
For equivalent section curve generating, it is small to shape the scope of application.The shortcomings that die forming method, is: needing to design and manufactures dedicated mould
Tool, the period is long, and manufacturing cost is high.Since the above method has the shortcomings that inevitable, it is not suitable for the multiple material work of single-piece production
Fill template forming.It is practical according to production, need to invent a kind of method for template forming, this method is required to be suitable for each
The template forming of the multiple material tooling of kind, forming accuracy is high, and stress stress is small after forming.
Summary of the invention
The object of the present invention is to provide the manufacturing process and shaping dies of a kind of multiple material tooling template, this method can be applicable in
In the template forming of various multiple material toolings, forming accuracy is high, and stress stress is small after forming.
To achieve the above objectives, the present invention, which adopts the following technical scheme that, is achieved:
A kind of shaping dies of multiple material tooling template, including upper plate, lower plate and be fixed on upper plate and lower plate
Multiple flexible punch units, the flexible punch unit includes spherical formed punch, adjustment structure, mandril, upper plate and lower plate
On be provided with mandril mounting groove, mandril is fixed in mounting groove, and adjustment structure setting adjusts ball between mandril and spherical formed punch
The height of shape formed punch is respectively formed model face and drag face.
Its manufacturing process key step are as follows:
The cube theory digital-to-analogue and actual resilience coefficient of 1 foundation template calculate upper plate and bottom by CATIA software
Each spherical shape formed punch Z value on plate；
2 carry out the adjustment of spherical formed punch Z value on upper and lower bottom plate by mandril, adjustment structure；
3 are individually fixed in upper plate, lower plate on the formed punch and pedestal of hydraulic press；
The spherical formed punch oiling of 4 pairs of upper plates and lower plate increases lubrication；
5 are placed in the template that need to be shaped on the spherical formed punch of lower plate；
6 operation hydraulic presses, move down upper plate, until the spherical formed punch of upper and lower bottom plate is closed；
7 pressure maintainings 10 minutes；
8 move up upper plate；
9 check template type face with wooden template.
The advantage of the invention is that can be by adjusting spherical height of punch, to shape different curvature, different shape
Multiple material tooling template.Compared to conventional method, forming period is short, and forming accuracy is high, and forming is at low cost, and stress is small after forming.
With practical value.
The present invention is described in further detail with reference to the accompanying drawings and embodiments.
Detailed description of the invention
Model face schematic diagram on Fig. 1 shaping dies
Fig. 2 shaping dies drag face schematic diagram
Explanation: 1, upper plate is numbered in figure；2, bolt；3, mandril；4, studs；5, cushion block is adjusted；6, gasket is adjusted；
7, spherical formed punch；8, template；9, lower plate.
Specific embodiment
Referring to Fig. 1, Fig. 2, a kind of manufacturing process and shaping dies of multiple material tooling template, including upper plate, lower plate and
The multiple flexible punch units being fixed on upper plate and lower plate.Flexible punch unit is by mandril 3, adjustment structure, spherical punching
First 7 composition.Upper mold can be considered as to be made of upper plate 1 and the flexible punch unit being fixed on upper plate 1, and lower die can be considered as
It is made of lower plate 9 and the flexible punch unit being fixed on lower plate 9.It is adjustment 5 He of cushion block that structure is adjusted in the present embodiment
Adjust gasket 6.Mandril 3 is fixed in mounting groove with bolt 2, and adjustment structure setting is between mandril and spherical formed punch and by double
Hook bolt 4 connects.The combination of mandril 3, adjustment cushion block 5, adjustment gasket 6 adjusts the height of spherical formed punch 7, forms upper die and lower die
Type face, pass through punching press complete template accurate molding.
Its manufacturing process key step are as follows:
1) it is calculated in upper die and lower die according to the cube theory digital-to-analogue of template and actual resilience coefficient by CATIA software
The Z value of each spherical shape formed punch 7；
2) tune of the Z value of upper die and lower die spherical shape formed punch 7 is carried out by the combination of mandril 3, adjustment cushion block 5, adjustment gasket 6
It is whole；
3) upper die and lower die are individually fixed on the formed punch and pedestal of hydraulic press；
4) to 7 oiling of spherical formed punch of upper die and lower die, increase lubrication；
5) template 8 that need to be shaped is placed in lower die；
6) hydraulic press is operated, upper mold is moved down, until upper and lower mould is closed；
7) pressure maintaining 10 minutes；
8) upper mold is moved up；
9) the type face accuracy of template 8 is checked with wooden template.
