Abstract
The utility model relates to a sand paving and compaction device for 3D printing, and belongs to the field of powdered material forming production devices. The sand paving and compaction device comprises a sand material bin, wherein the bottom of a bracket of the sand material bin is mounted on linear guide rail driving mechanisms; a helical conveyer is horizontally arranged in the sand material bin; a sand sieve is horizontally arranged below the helical conveyer; a sand outlet is formed below the sand sieve; a sand scraper blade is arranged on the rear part of the sand outlet and is hinged to the sand material bin through a connection rod; a bearing connection block is arranged on the sand scraper blade; an eccentric shaft is mounted on the bearing connection block through bearings; an eccentric shaft motor for driving the eccentric shaft to rotate is mounted at the shaft end of the eccentric shaft. The sand paving and compaction device for the 3D printing can ensure that sand materials can be uniformly spread and enable the sand materials to be compact, so that the optimal state of each layer before printing is achieved, and indexes, such as the precision and the compactness, of a manufactured sand mold, meet a casting standard; the problem that the surface quality of a casting is poor is solved. The device is suitable for the 3D printing casting industry.
Description
Technical field
The utility model relates to a kind of dusty material shaping process units, and the powder that particularly 3D prints is paved mechanism.
Background technology
In prior art, sand mold 3D printing device, the function that its sanding system only has sand material to carry and every layer of sand material paved, the problem of two aspects below existing: the flatness that is on the one hand the layer of sand surface after tiling does not detect and feeds back, and is that the layer of sand after tiling does not have consolidation on the other hand.Just there is very large problem in the sand mold intensity producing like this, just the foundry goods of producing has corresponding casting flaw, as: surface quality of continuous castings is poor, has the problems such as scab, vein, low precision.
Utility model content
The purpose of this utility model is to provide sanding and the mold compacting device that a kind of 3D prints, make it not only can carry, pave sand material, also can make every one deck sand material consolidation simultaneously, reach the optimum state before every layer of printing, finally reach the sand mold producing and reach casting standard in the index such as precision and the degree of packing.
The purpose of this utility model is achieved in that sanding and the mold compacting device that a kind of 3D prints, comprise sand feed bin, the frame bottom of sand feed bin is arranged on line slideway driving mechanism, in sand feed bin, level is provided with auger conveyor, auger conveyor lower horizontal is provided with sieve sand net, sieve sand side off the net is provided with sand export, described sand export rear portion is provided with stragith edge, stragith edge is hinged on sand feed bin through connecting rod, stragith edge is provided with bearing contiguous block, on bearing contiguous block, through bearing, eccentric shaft is installed, the axle head of eccentric shaft is provided with the eccentric shaft motor that drives eccentric shaft to rotate.
When the utility model work, under the driving of line slideway driving mechanism, sand feed bin can seesaw.Sand material adds sand feed bin, and augur, is evenly distributed in whole sand feed bin inside sand material simultaneously.The sand material of sand feed bin inside, after screened sand net filtration, evenly spills from sand export, drops on workbench, when line slideway driving mechanism seesaws, drives stragith edge synchronously the sand material spilling to be struck off.In sanding process, under eccentric shaft motor drives, eccentric shaft is made high speed rotary motion under the support of bearing, drives stragith edge dither, and like this, sand material is under the dither of stragith edge, simultaneously by vibration ramming.Compared with prior art, the utility model can not only ensure that sand material is evenly shakeout, and can make sand material closely knit, reaches the optimum state before every layer of printing, finally reaches the sand mold producing and reaches casting standard in the index such as precision and the degree of packing.Solved the poor problem of surface quality of continuous castings, this device is applicable to 3D and prints casting industry.
For ensureing that sand material is more prone to by scraping blade and closely knit, described stragith edge and horizontal plane angle are 0 ~ 5 °.
For ease of adding sand, one end, described sand feed bin top is provided with infundibulate and adds sand mouth.For controlling the material level that adds sand, in described sand feed bin, be provided with the level sensor that stops adding sand for controlling, after sand feed bin medium sand material is filled it up with, level sensor transmitted signal control sanding device stops adding sand.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model partial structurtes left views.
Wherein, 1 sand feed bin, 2 level sensors, 3 auger conveyors, 4 carry motor, 5 sand exports, 6 sieve sand nets, 7 stragith edges, 8 eccentric shafts, 9 bearings, 10 eccentric shaft motors, 11 line slideway driving mechanisms, 12 servomotors, 13 workbenches, 14 add sand mouth, 15 connecting rods, 16 contiguous blocks.
Detailed description of the invention
As illustrated in fig. 1 and 2, for a kind of sanding and mold compacting device of 3D printing, comprise sand feed bin 1, sand feed bin 1 one end, top is provided with infundibulate and adds sand mouth 14, the frame bottom of sand feed bin 1 is arranged on line slideway driving mechanism 11, and line slideway driving mechanism 11 can drive sand feed bin 1 to seesaw by servomotor 12; The interior level of sand feed bin 1 is provided with auger conveyor 3, and auger conveyor 3 ends are provided with carries motor 4, carries motor 4 while rotating, sand material can be carried to the other end from sand feed bin 1 one end, to sand material is evenly paved sand feed bin 1 is interior; Auger conveyor 3 lower horizontal are provided with sieve sand net 6, sieve sand net 6 belows are provided with sand export 5, the position of sand export 5 should be corresponding with workbench 13, sand export 5 rear portions are provided with stragith edge 7, stragith edge 7 is hinged on sand feed bin through connecting rod 15, stragith edge 7 is provided with bearing contiguous block 16, on bearing contiguous block 16, through bearing 9, eccentric shaft 8 is installed, and the axle head of eccentric shaft 8 is provided with the eccentric shaft motor 10 that drives eccentric shaft 8 to rotate; Described stragith edge 7 is 0 ~ 5 ° with horizontal plane angle.
In sand feed bin 1, be provided with the level sensor 2 that stops adding sand for controlling.
When work, under the driving of line slideway driving mechanism 11, sand feed bin 1 can seesaw, and sand material adds sand feed bin 1 from adding sand mouth, and auger conveyor 3 rotates simultaneously, and sand material is evenly distributed in to whole sand feed bin 1 inside.After sand feed bin 1 medium sand material is filled it up with, level sensor 2 transmitted signal control sanding devices stop adding sand.The sand material of sand feed bin 1 inside, after screened sand net 6 filters, evenly spills from sand export 5, drops on workbench 13, when line slideway driving mechanism 11 seesaws, drives stragith edge 7 synchronously the sand material spilling to be struck off.In sanding process, under eccentric shaft motor 10 drives, eccentric shaft 8 is made high speed rotary motion under the support of bearing 9, drive stragith edge 7 dithers, like this, sand material is under the dither of stragith edge 7, by stragith edge 7 vibration rammings, avoid occurring the problem of scab, vein, low precision simultaneously.The sand mold producing can reach casting standard in the index such as precision and the degree of packing.
