Abstract
The present invention relates to a new-type three-dimensional knitting machine, including spindle, drive device, machine frame and forming device, which is characterized by that it also includes fixed knitting guide way which is fixed on the machine frame and is formed from criss-cross uniformly-spaced and net-like arraged umbrella blocks and rectangular positioning block whose upper portion is supported by two adjacent umbrella blocks and whose lower portion is inserted into two adjacent umbrella blocks. This design can reduce the requirements for coorking accuracy of knitting guide way and positioning accuracy after the spindle is moved, so that it not only effectively can prevent "spindle" from being got stuck, but also can reduce manufacture and maintenance cost, at the same time it overcomes the difficult axial yarn lead-in problem.
Description
Patent of the present invention relates to a kind of three-dimensional knitter, and it belongs to the process equipment of 3 D weaving preform.
The important form that advanced composite material strengthens structure is the 3 D weaving preform.Conventional composite materials adopts the form of veneer structure, and more weak interlayer performance is the one of the main reasons that composite lost efficacy.The 3 D weaving preform has good structural integrity, when improving the composite overall performance, has improved the impact flexibility and the damage tolerance of composite.And 3 D weaving has the ability of working special-shaped cross section preform, can satisfy the requirement of the clean type processing of composite element.Therefore, the 3 D weaving preform is the new high-tech product of researching and developing in the world in recent years, and the 3 D weaving technology is space flight, aviation, military project and other special dimension crucial technology of preparing with composite.
The 3 D weaving machine is the process equipment of 3 D weaving preform.It is the feature of 3 D weaving that many spindles are synchronized with the movement, and the braiding guide rail is the basis that guarantees correct location of spindle and motion.On existing 3 D weaving machine, the patent of being announced with Chinese patent publication number CN 1171462A is an example, and as shown in Figure 1, the braiding guide rail is made up of many T-slots that carry on the yarn row 10.By slide rail 11, carry the carry yarn row of yarn row 10 on being fixed in frame 9 and support motion in 12.Equidistantly had T-slot at every year on the yarn row 10, the built-in spindle 7 of each groove, many years yarn rows 10 are arranged in parallel and form the braiding platform, and T-slot is listed as to alignment, to form the motion guide rail of spindle 7.Under drive unit 8,8 ' effect, spindle 7 is gone up with carrying yarn row 10 in a direction (laterally) and is moved, and displacement should be the integral multiple of T-slot pitch, makes T-slot remain row to alignment; The T-slot that spindle 7 has alignd in vertical direction (vertically) upper edge with it moves, and spindle 7 each distances that move should be carries the integral multiple that yarn is arranged 10 width, guaranteed that year yarn row 10 is in horizontal moving freely.Like this, driven spindle 7 and year yarn row 10 can realize spindle 7 moving on the braiding platform in length and breadth, and the knitting yarn 3 that spindle 7 is drawn is interweaving perpendicular to shaped device 2 places above the braiding platform, acquisition 3 D weaving preform 1.
From above-mentioned knitting principle as can be seen, the braiding guide rail on the existing 3 D weaving machine is portable, and the shape of portable braiding guide rail is not only relevant with the machining accuracy of T-slot with the position, and relevant with year location of yarn row 10 after moving.Therefore, be listed as to alignment, require high the form and position tolerance of T-slot and year yarn row's 10 running fix in order to make portable braiding guide rail.Simultaneously, can move freely in order to make a year yarn row 10, dimensional accuracy and the running fix thereof in T-slot also has very high requirement for spindle 7.Otherwise, will cause so-called " stuck " phenomenon.In addition, the structure of portable braiding guide rail makes and is parallel to drawing of 3 D weaving preform 1 axial yarn and is difficult to realize.
The object of the present invention is to provide a kind of novel 3 D weaving machine, to overcome above-mentioned shortcoming.
Technical scheme of the present invention is achieved in that three-dimensional knitter, it comprises spindle 7, drive unit 8,8 ', frame 9, shaped device 2, it is characterized in that also comprising by being fixed on fixed braiding guide rail and the top that the umbrella shape piece 4 that equidistantly is netted arrangement on the frame 9 in length and breadth forms and support that the bottom embeds the rectangle locating piece 6 in two adjacent umbrella shape pieces 4 by two adjacent umbrella shape pieces 4.
Compared with prior art, advantage of the present invention is:
Adopt the fixed braiding guide rail of umbrella shape piece 4 compositions that equidistantly are netted arrangement in length and breadth, reduced to the guide rail machining accuracy with to spindle 7 and moved the requirement of positioning accuracy afterwards.This has not only prevented spindle 7 " stuck " phenomenon at the volley effectively, has also reduced the expense of making and safeguarding.Owing to used fixed braiding guide rail structure, also solved the problem that the existing portable structure that weaves guide rail makes the introducing of axial yarn 5 be difficult to realize simultaneously.
Below in conjunction with drawings and Examples the present invention is further described below:
Fig. 1 is existing 3 D weaving machine structural representation
Among Fig. 1,1-3 D weaving preform, the 2-shaped device, the 3-knitting yarn, the 7-spindle, 8,8 '-drive unit, the 9-frame, 10-carries yarn row, and 11-slide rail, 12-carry yarn row and support
Fig. 2 is a three-dimensional knitter structural representation of the present invention
Among Fig. 2,1-3 D weaving preform, the 2-shaped device, the 3-knitting yarn, 4-umbrella shape piece, the 5-axial yarn, 6-rectangle locating piece, the 7-spindle, 8,8 '-drive unit, the 9-frame
Fig. 3 is a matching relationship schematic diagram between adjacent two spindles of being arranged in delegation, umbrella shape piece, the rectangle locating piece
Among Fig. 3,4-umbrella shape piece, 6-rectangle locating piece, 7-spindle
As shown in Figures 2 and 3, the present invention has adopted fixed braiding guide rail.Fixed braiding guide rail is formed by being fixed on the umbrella shape piece 4 that equidistantly is netted arrangement on the frame 9 in length and breadth, umbrella shape piece 4 is made up of two rectangular blocks up and down, two rectangular blocks can be monoblock type or assembly type, umbrella shape piece 4 longitudinal sections are the T font, umbrella shape piece 4 adopts metal material, and central authorities have circular hole, as the passage of axial yarn 5, keep equal spacing between the adjacent umbrella shape piece 4, to form fixed in length and breadth braiding guide rail.Spindle 7 bases embed in the fixed braiding guide rail of being made up of umbrella shape piece 4, and the distance that adjacent spindle is 7 is determined by the rectangle locating piece 6 of 7 on spindle.Rectangle locating piece 6 is made up of two rectangular blocks up and down, and two rectangular blocks can be monoblock type or assembly type, and the employing nonmetallic materials are to improve friction condition.Rectangle locating piece 6 tops are supported by two adjacent umbrella shape pieces 4, and the bottom embeds in two adjacent umbrella shape pieces 4, can be longitudinally or laterally mobile jointly with spindle 7.Like this, spindle 7 relative positioning accuracies with fixed braiding guide rail are rectangle locating piece 6 assurances by simple shape, thereby have reduced processing and maintenance cost.Every row (or row) spindle 7 is by vapour-pressure type or fluid pressure type drive unit 8,8 ', can move back and forth vertical along fixed braiding guide rail (or laterally), its distance that moves should equal the integral multiple of fixed braiding guide rail spacing, is positioned at all the time in length and breadth on the cross-point of fixed braiding guide rail with the axle center that guarantees spindle 7.Driven spindle 7 longitudinally or laterally moves, the axial yarn 5 that makes the knitting yarn 3 on the spindle 7 and draw by umbrella shape piece 4 central circular holes interweaves in the space together, on shaped device 2, knit out and have rectangle or rectangle combined shaped the profiled-cross-section braided fabric of (as I-shaped etc.), be referred to as 3 D weaving preform 1.
