Detailed description of the invention
Below in conjunction with accompanying drawing, explanation is further explained to the application.
What the application provided the be used for preformed pressing equipment of producd fibers enhanced type composite material, its basic structure composition as shown in Figure 2, comprise support 1, column 2 on support, motor 3, bent axle 4, total pressing block 5, upper module 6, lower module 7, bracing frame 21 and upper ground way 8 and lower ground way 9, fixed slideway 8 is connected with upper module 6 and lower module 7 respectively with lower ground way 9, wherein go up ground way 8 and be fixed on support 1 upper end, the below of column 2, described lower ground way 9 is located at the bottom of support 1, also can fix on the ground, support frame as described above 21 can be pressed from both sides steady by mechanical arm fixture, be convenient to carrying.In punching course, bracing frame 21 is fixed on support 1, between upper module 6 and lower module 7, bracing frame is divided into upper bracket 211 and lower carriage 212 two parts, and in order to the fixing preformed tension force making to be preformed in punching course and keep certain simultaneously, its concrete structure as shown in Figure 7; The top that described total pressing block 5 is located at column 2 is connected with motor 3 by bent axle 4, can pump along column 2; Described upper module 6 and lower module 7 comprise at least one pressing block 10 and at least one slide-bar 11 respectively, the pressing block 10 shape equity on described upper module 6 and lower module 7, quantity can equity also can not be reciprocity; The end of described pressing block 10 is connected with slide-bar 11, described slide-bar 11 connects with corresponding upper ground way 8 or lower ground way 9 respectively, upper ground way 8 is fixed on support 1 and column 2, and static in whole punching course, slide-bar 11 can slide up and down in slideway 8 or 9; More than 70 DEG C are remained on by heating system 15 for whole equipment in punching course.
When punching course carries out fully, access refrigeration system 16, three-dimensional laying is made to be cooled to room temperature rapidly, setting agent cooling curing, ensure preformed geometrical shape stability, as shown in Figure 5, then cut off the excess fiber silk of periphery, remove the good preformed of punching press by the mechanical arm 17 that fixture is housed and store, as shown in Figure 6.
By the said equipment, two dimensional surface preformed is originally fashioned into 3D shape, filament is different from traditional metal or plastics, itself is more open, but radial direction has tensile resistance does not have anti-pressure ability, so whole punching course will keep certain internal tension, to prevent fiber crimp or excessive sideslip, if the fluctuating of die surface is excessive, the sideslip of fiber can be caused uncontrollable, there is fiber crimp, fracture, laying fold, the phenomenons such as cracking, for ensureing filametntary in preformed being uniformly distributed, trend rationally, upper and lower stamping die score of the game is slit into some pressing blocks by the application, upper and lower correspondence, it is more careful to divide for the part that surfaces slope is larger, the object of piecemeal greatly improves pressing equipment and the contact area of filament in punching course, increase local friction, prevent fold from producing.Each pressing block can move up and down along slideway.At initial position, regulate micro-tensioning system, upper and lower pressing block contacts gently in centre, and therebetween plane preformed forms Multi-contact; Between the silk of upper and lower module peace face, can also lay the good material film 12 of ductility, material film ensure that preformed uniform force, ensures the clean of mould simultaneously.
In practical work process, four pressing blocks are comprised respectively for upper module and lower module, as shown in figures 1 to 6, first to heat the plane preformed preparing to carry out punching press, this example is heated by external heating system 15 and realizes, specifically see Fig. 1, heating system 15 can be infrared lamp, electric furnace, hot blast etc.Carry out heating is infiltrate in filament to make the setting agent of plane pre-shaped surface melt, because setting agent is at room temperature solid-state (setting agent normally sprays to fiber surface in the piddler process middle and later periods, or sprays to fabric face before flat fabric lay is good).In the punching press stage, setting agent needs by heat activation, makes it to have cohesive force.The initial position of pressing equipment is respectively by elastic device 13 and micro-tensioning system 14(such as adjustable bolt) control, after punching course starts, total pressing block 5 moves downward under the drive of motor bent axle 4, the pressing block 10 of top presses downwards, promote fiber and the decline of below pressing block, the startup of top pressing block has precedence, and 4. 3. 1. 2. the pressing block in upper module contact main pressing block in order and move downward; The pressing block of lower module according to 6. 7. 8. order 5. start successively and decline.In the process, the fiber laying of upper and lower module and centre keeps Multi-contact and suitable contact force, and upper module continues descending, and continued to be compacted on lower module by precursor, whole process all will keep heated condition.After punching press completes, cooling preformed, upper module rises, and each pressing block of lower module rises according to contrary order and sets back: because there is the existence of material film 12, and this process can than comparatively fast, overlying material film is under the effect of its own resilient, also can pack up, under the elastic force of underlying materials film, three-dimensional preformed can be ejected, then by help that is artificial or mechanical arm, the precursor preform fabric completed is transported to storage location.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
