Description
Technical field
The utility model relates to a kind of powder laying apparatus, is specifically related to a kind of power spreading device for quick forming fabri-cation.
Background technology
The technical way of quick forming fabri-cation is 3D printing technique, is all much adopt powder as raw material in 3D printing technique, and layer is finally shaping.This novel Rapid Manufacturing Technology directly can obtain the profiled member of arbitrary shape, not by the impact of the complexity of profiled member, for design provides the higher free degree, processing technology before simultaneously comparing, its processing cost is low, process velocity is fast, is particularly useful for experimental verification and the small lot batch manufacture of researching and developing early stage, has broad application prospects.
Present stage, use the various Rapid Manufacturing Technology of power spreading device, all there is following similar problem:
(1) powder layer thickness is spread uneven;
(2) profiled member density is low;
(3) profiled member is easily shifted.
Above problem can have a strong impact on final quantity of sintered parts, urgently to be resolved hurrily.
Summary of the invention
The utility model will solve technical problem is for the deficiencies in the prior art, provides a kind of even for spreading powder, the shaping fast and power spreading device that profiled member density is high.
In order to achieve the above object, the utility model is by the following technical solutions:
A kind of power spreading device for quick forming fabri-cation, comprise paving powder debulking systems and formation system, it is characterized in that: described paving powder debulking systems comprises scraper plate, be arranged on the hopper of described scraper plate both sides, be positioned at the baffle plate of described hopper lower end, drive described baffle plate to open blanking motor that described hopper carries out blanking, be arranged on the lifting drive on described hopper and be arranged on the press roll component of described lifting drive output, described press roll component comprises roller seat, be arranged on the pressure roller on described roller seat and pressure roller drive motors, described formation system comprises moulding cylinder and is arranged on the lifting body in described moulding cylinder, described pressure roller acts on the upper surface of described moulding cylinder.
A recovery cylinder is respectively arranged with in the both sides of described moulding cylinder.
Described lifting drive is cylinder.
Described lifting body comprises piston apparatus and arranges the jacking motor of described piston apparatus lower end.
Described hopper is connected with described blanking motor by a screw mechanism.
The utility model power spreading device, two hoppers are separately fixed at the both sides of scraper plate, scraper plate have motor and screw mechanism, can control the motion of baffle plate, and then control the openings of sizes of hopper; The both sides of two pressure roller apportion scraper plates and powder bucket, each pressure roller has a motor, can control separately rotation direction and the velocity of rotation of pressure roller, and two roller frames are separately fixed on two cylinders, and two pressure rollers can be driven to move up and down; Two both sides of reclaiming cylinder apportion moulding cylinders, and size is less, has the piston apparatus that can move up and down in moulding cylinder, servomotor therewith piston apparatus connects, can the motion of control piston device.
Compared with prior art, it is even that the utility model power spreading device has paving powder thickness, the high and shaping advantage such as soon of profiled member pressure roller pressure density.
Accompanying drawing explanation

Fig. 3 is the structural representation of formation system.
Wherein: 1, spread powder debulking systems, 11, scraper plate, 12, hopper, 13, baffle plate, 14, blanking motor, 15, pressure roller, 16, pressure roller drive motors, 17, cylinder, 2, formation system, 21, moulding cylinder, 22, reclaim cylinder, 23, jacking motor.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is elaborated:
As indicated with 1, a kind of power spreading device for quick forming fabri-cation, comprises paving powder debulking systems 1 and formation system 2.Wherein, paving powder debulking systems 1 as shown in Figure 2, comprise scraper plate 11, be arranged on the hopper 12 of scraper plate both sides, be positioned at the baffle plate 13 of hopper lower end, drive baffle plate open hopper carry out blanking blanking motor 14, be arranged on the lifting drive on hopper and be arranged on the press roll component of lifting drive output.Wherein, lifting drive selects cylinder 17, and press roll component comprises roller seat, be arranged on pressure roller 15 on roller seat and pressure roller drive motors 16.As shown in Figure 3, the lifting body comprise moulding cylinder 21, reclaiming cylinder 22 and be arranged in moulding cylinder, lifting body comprises piston apparatus and arranges the jacking motor 23 of piston apparatus lower end formation system 2.
Two powder buckets are separately fixed at the both sides of scraper plate, scraper plate have motor and screw mechanism, can control the motion of baffle plate, and then control the openings of sizes of powder bucket; The both sides of two pressure roller apportion scraper plates and powder bucket, each pressure roller has a motor, can control separately rotation direction and the velocity of rotation of pressure roller, and two roller frames are separately fixed on two cylinders, and two pressure rollers can be driven to move up and down; Two both sides of reclaiming cylinder apportion moulding cylinders, and size is less, has the piston apparatus that can move up and down in moulding cylinder, servomotor therewith piston apparatus connects, can the motion of control piston device.
Specific works mode is as follows: if now spread the left side that powder system is positioned at moulding cylinder, after one deck powder processing structure, piston apparatus in Serve Motor Control moulding cylinder moves down certain distance, pressure roller on the right side of paving powder system also moves down same distance, make pressure roller and bisque tangent, left side compression roller heights is constant, paving powder system starts at the uniform velocity to move right, simultaneously, right-hand apron is opened, powder constantly falls from powder bucket, powder strikes off by scraper plate, more than powder blow off together, until more than powder arrive reclaim cylinder, two pressure rollers start to rotate, the velocity of rotation of pressure roller can ensure that the superficial velocity of pressure roller is identical with the speed of paving powder system motion, and rotation direction is clockwise, right side pressure roller can fix manufactured part, part is prevented to be shifted, left side pressure roller can compacting bisque, increase density, after whole paving powder system moves to the right side of moulding cylinder, right side pressure roller is elevated to original height, flapper closure, stop powder feeding, system of processing can be processed bisque.After this bisque process finishing, paving powder system starts to move from right to left, the piston apparatus of moulding cylinder declines certain altitude again, this is that left side pressure roller declines, left side baffle plate is opened, the rotation direction of two pressure rollers becomes counterclockwise, until paving powder system moves to the left side of moulding cylinder, and so forth.
