Abstract
The utility model relates to a multi-line segment laser fast forming apparatus, comprising an information processing part, a photology part, a machine part and a material containing barrel. A carbon dioxide laser, a line light source system, a liquid crystal mask, a lens and a holophote in the photology part are fixed on a scanning platform in sequence, and the liquid crystal mask is connected with computer I/O interfaces in the information processing part. The normal direction of a reflector and an optic axis are in 45 DEG, and the laser forming platform in the machine part and the normal of the lens are in 45 DEG. The utility model has the advantages of high manufacture speed, smaller thermal deformation of finished products, denser organization of finished products and higher strength of finished products.
Description
The utility model belongs to the computer integrated manufacturing system field, particularly a kind of laser fast shaping device.
Up to the present, the external most employing of rapid molding device laser point scanning is made part or model to liquid state or pulverulent material.Their common drawback is that manufacturing speed is bigger than the thermal deformation in slow and this journey of moulding.Existing a kind of rapid molding device that adopts length-varying linear scanning to replace spot scan.But the shortcoming of this device is: 1. the laser line segment used as a rule more than two sections or two sections of the cross section of part scans simultaneously.If have only a laser line segment to scan, will reduce shaping speed exponentially; 2. single laser line segment scans, and will waste energy of lasers when moulding; 3. with the scheme of mechanical automatic adjusting laser rays segment length, structure is complicated.If intend adopting many laser scanning systems, then will be difficult to realize because of structure is too complicated in order to increase plastic dimensions.
The purpose of this utility model is to provide a kind of device, overcomes the shortcoming of above-mentioned laser scanning or length-varying linear scanning, realizes making the entity finished product with the high-quality material method that increases fast.While is the shakedown dusting bed of material evenly, and to powder layer compacting equably, evenly fine and close in the hope of the entity finished product internal structure after the moulding.
The utility model comprises information processing part, opticator, mechanism's part and bucket.Carbon dioxide laser in the opticator, line source system, liquid crystal mask, lens, total reflective mirror are fixed on the scanning platform along optical axis successively.The I/O mouth of the computer in liquid crystal mask and the information processing part links to each other.The normal direction of lens and optical axis are 45 degree.The laser formation platform in mechanism's part and the normal direction of lens are 45 degree and are provided with.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the utility model selectivity multi-line section laser scanning part-structure schematic diagram.
Fig. 2 is the utility model stone and compaction part structural representation.
Fig. 3 is the structural representation of the utility model bucket.
Fig. 1 is dynamic auto adjustment laser rays hop count order, length and positional structure partial graph.Carbon dioxide laser 4 is fixed on the numerical control one-dimensional scanning platform 7, line source system 5 parallel laser instrument laser output the place aheads that are placed on, and the light output end of online light-source system 5 is placed high resolution square liquid crystal mask 2, and this mask is controlled it by the one control voltage of I/O mouth output in the computer 1.Laser beam by mask output focuses on through lens 3.3 position and 4,5 and 2 optical axis overlap placement on same horizontal direction.The 6th, total reflective mirror, its normal orientation and optical axis are at 45 to be positioned on the scanning platform 7.9 is the laser formation processing platform, and its position is in the direction vertical with incident light 8, the focal length of the sub-lens such as optical path length 3 between its horizontal surface and the lens.
Fig. 2 is stone and compaction part, material cylinder 10 and working cylinder 12 parallel placements, and wherein piston 11,13 can move up and down, and connects with stepper motor respectively by piston rod.Roller 14 is by motor-driven, and on the roller bearing electromagnetic exciter is installed.
Fig. 3 is the bucket structure chart.This bucket 16 is one cylindrical, and its slightly larger in diameter is in the diameter of material cylinder, and its bottom can be dialled the bucket end 17 of removing and inserting at any time by one and be formed.Cylindrical bucket 16 diameters are greater than the diameter of material cylinder 10, and the bucket end is provided with linkage.
The utility model is by computer, selectivity multi-line section laser scanning part, powder adds part and bucket is formed, and as mask, computer carries out dynamic modulation by the two-dimensional section data output control signal of layering to liquid crystal mask with the strip LCDs.The sheet laser beam just forms corresponding multi-line section laser by behind this mask.In the laser scanning process, the number of above-mentioned line segment, the even signal of pressing computer output in length and position is done dynamically to change, thereby in single pass, just can form one deck solid cross section, and and the clinkering of preceding one deck solid, sintering or be solidified togather, and then new powder or the light-cured resin of layer overlay, scan again, till forming complete threedimensional solid finished product.Its powder shop is applied and compacting is all realized by a roller, with the roller of reverse rotation the even shakedown of powder is applied in the processing district, with roller ground this layer powder compacting that is rotated in the forward.
Compared with prior art, the utlity model has following advantage: manufacturing speed is higher, finished product Thermal deformation littler, finished product organizes densification and intensity higher. The utility model makes laser quick Shaped device is more perfect.
