Abstract
A kind of twin shaft paving powder formula selective laser sintering workbench, relates to the powder sintered rapid forming equipment that plurality of raw materials can be used to be processed of a kind of new construction.Requiring operator low, it includes laser instrument, optical system, scanning mirror, powder cylinder, powder-laying roller and work platforms.The plurality of advantages such as this invention has can meet higher processing request, and simple in construction is easy to operate, practical.
Description
Technical field:
The present invention relates to the rapidform machine of a kind of new construction, particularly can meet on same workpiece the production requirement using plurality of raw materials.
Background technology:
Along with the progress of science and technology, production and processing mode is also weeded out the old and bring forth the new constantly.Rapid forming equipment, through development for many years, is widely applied in actual production.Powder sintered rapid shaping is that the part accurately, quickly and conveniently producing given shape provides a road.But, conventional powder sintered workbench is often made with the powder of single kind and produces, when there being particular/special requirement in production technology, such as: require to use bonding material, in order to the bonding strength between strengthening every layer.Now, conventional powder sintered workbench just encounters a bottleneck.
Summary of the invention:
It is an object of the invention to provide and a kind of can use various powders, rapid processing, meet that special process requirements, processing is simple, the rapid forming equipment of suggestion for operation.
For achieving the above object, the technical solution adopted in the present invention is:
The improvement that the workbench of this type in the past is carried out in principle by twin shaft paving powder formula selective laser sintering workbench.In the plane at work platforms place, X, Y both direction is placed a Zu Pu powder mechanism respectively.First, the lay powders A on work platforms of powder-laying roller in the X direction, afterwards, laser beam is under control of the computer, according to the profile of target part, the solid section made is scanned, being that the powder in scanned region melts and coheres, and the powder of other parts still keeps fluffy, and as the support of next layer.Afterwards, work platforms declines, and powder-laying roller lay powder B in the Y direction, equally, bisque B is sintered under the guiding of computer by laser beam.The like, the successively processing of multiple material can be carried out on Same Part.
It addition, because employing the powder of two kinds of different materials, then when sintering different powder, the power of laser beam also can produce difference because the processing request of dusty material is different from action time.At this moment, it is necessary to utilize computer control system to carry out distinguishing control.
Beneficial effect:
This rapid forming equipment, the most than ever, it expands the species number using raw material on a workpiece, meets higher processing request, simultaneously, whole device structure is simple, and practical, the work that control system undertakes is many, automatically carry out the switching of Sintering mode, for user, easy to use, it is not necessary to too many training can be handled.

Detailed description of the invention:
Below in conjunction with embodiment and compare accompanying drawing the present invention is described in further details.
In the plane at work platforms (8) place, centered by work platforms, in orthogonal both direction, dispose one group of power spreading device respectively respectively, including powder cylinder and powder-laying roller.Its each several part specifically moves as follows, under the control of computer control system, production requirement according to workpiece, paving powder rod (4) is paved with powder in paving powder cylinder 5, its one end is connected with the cylinder barrel of the hydraulic cylinder (9) of side, under the promotion of hydraulic system, paving powder rod 4 can be to opposite one side shifting, when moving to workbench (8) surface, can carry out on workbench 8 surface spreading powder work, after paving powder completes, powder in sintering zone is sintered under the accurate control of terminal by laser instrument (3), the powder of sintering zone melts after laser sintered and coheres, remaining part still keeps fluffy.After having sintered one layer, motor (11) computer controls lower startup, its output power drives little gear (17), gear wheel (9) to rotate, gear wheel (9) driven gear (18) rotates, gear (18) and tooth bar mating band station (8) of starting building moves down, paving powder rod (4) is under hydraulic system drives, it is achieved rewind, returns to powder cylinder (5).Upper berth powder rod (6) the most in the Y direction, under the driving of hydraulic cylinder (12), to opposite one side shifting, after arriving work platforms (8), carry out spreading powder, after paving powder completes, laser instrument is under the control of the computer, the powder of sintering zone is sintered, after this layer of sintering completes, motor (11) computer controls lower startup, its output power drives little gear (17), gear wheel (9) rotates, gear wheel (9) driven gear (18) rotates, gear (18) and tooth bar mating band station (8) of starting building moves down, paving powder rod (6) is under hydraulic system drives, realize rewind, return to powder cylinder (7) place.The whole course of processing is exactly
The most constantly repeat motion recited above, machine until whole.
In the whole course of processing, control the computer control system in scanning system and control laser instrument (1), optical system (2), scanning mirror (3), each layer of powder is sintered.Here to comprise the data of different dusty material in computer control system, a data includes the output etc. when processing temperature, sintering.Further, every suit data after any one group of paving powder early frost system completes to spread powder, to call corresponding process data with the power spreading device pairing depositing corresponding dusty material automatically.
The present invention is not limited to above-mentioned concrete pattern.Described detailed description of the invention can be made multiple amendment, supplements or use similar mode to substitute by those skilled in the art; without departing from the spirit of the present invention or surmount scope defined in appended claims, all in scope of the claimed of the present invention.
