Represent technology.
In metal powder rapid forming equipment, especially selective laser melting rapid forming equipment (SLM), metal powder
The flatness of last powdering directly affects the Forming Quality of part, and powder-scraping device used in powdering system is hard scraper,
Once scraper clamp processing has slight deviations, it is possible to cause scraper arch curved and stress concentration, encircleing curved scraper influences powdering
Flatness, stress is concentrated so that scraper is easy to produce damaged and then is that bisque has scratch.And the powdering dress based on flexible scraper
It sets and just compensates for this defect, so that the part quality that metal powder rapid forming equipment prints is guaranteed.
Summary of the invention
The purpose of the present invention is to provide a kind of power spreading devices based on soft scraper, to solve on caused by the prior art
State multinomial defect.
A kind of power spreading device based on soft scraper, including driving shaft, two driving wheels, motor, two driven wheels, two it is same
Step band, doctor beam, scraper clamp and soft scraper, the output shaft of the motor are fixedly connected with the driving shaft by retarder, main
Moving axis left and right ends are fixedly attached there are two the driving wheel, and driving wheel is connected by synchronous belt driving synchronous with the driven wheel
It connects, the doctor beam is fixedly connected on synchronous belt, be fixed with scraper clamp below the doctor beam, in the scraper clamp
Equipped with docking protrusion, the soft scraper both ends be equipped with the docking groove for dock protrusion and being engaged by clamping, it is removable in scraper clamp
It unloads and is connected with soft scraper.
Preferably, the motor is servo motor.
Preferably, the soft scraper is using bone-free bar shaped scraper made of rubber material.
Preferably, doctor beam lower end surface both ends are fixed with the sliding block of L-type, and the sliding block is fixedly connected on the synchronization
The inside of band.
Preferably, the lower end surface of the doctor beam and the upper surface of synchronous belt keep certain gap, and doctor beam is located at same
Step band top.
The advantage of the invention is that：The soft scraper of rubber material of the present invention is fixed in doctor beam by scraper clamp, scraper
Beam moves left and right realization by synchronous belt drive and scrapes powder movement, and driving shaft, driving wheel and driven wheel fortune is driven by motor in synchronous belt
Dynamic to realize movement, soft scraper selectes corresponding rubber material according to environment, overcomes hard scraper lacking during installing and using
Point, and soft scraper tilts during traveling gently towards the direction opposite to the traveling direction, thus have to metal powder downward
Component can make the laying of metal powder have higher densification.

Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
As shown in Figures 1 to 6, a kind of power spreading device based on soft scraper, including driving shaft 1, two driving wheel 2, motor
3, two driven wheels, 4, two synchronous belts 5, doctor beam 6, scraper clamp 7 and soft scraper 8, the output shaft of the motor 3 is by subtracting
Fast device is fixedly connected with the driving shaft 1, and 1 left and right ends of driving shaft are fixedly attached there are two the driving wheel 2, and driving wheel 2 passes through
Synchronous belt 5 is synchronous with the driven wheel 4 to be drivingly connected, and is fixedly connected with the doctor beam 6 on synchronous belt 4, the doctor beam 6
Lower section is fixed with scraper clamp 7, and docking protrusion is equipped in the scraper clamp 7, and soft 8 both ends of scraper are equipped with and dock with described
The docking groove that protrusion is engaged by clamping is removably connected with soft scraper 8 in scraper clamp 7.
In the present embodiment, the motor 3 is servo motor.
In the present embodiment, the soft scraper 8 is using bone-free bar shaped scraper made of rubber material.
In the present embodiment, the 6 lower end surface both ends of doctor beam are fixed with the sliding block 61 of L-type, and the sliding block 61 is fixed to be connected
It connects in the inside of the synchronous belt 5.
In the present embodiment, the lower end surface of the doctor beam 6 and the upper surface of synchronous belt 5 keep certain gap, scraper
Beam 6 is located at 5 top of synchronous belt.
The operation principle of the present invention is that：Driving wheel 2 is driven to rotate by motor 3, driving wheel 2 is in synchronous belt 5 and actively
Under the drive of axis 1, doctor beam 6, which by the drive of synchronous belt 5 moves left and right realization, scrapes powder and acts, flatness motor 3 of the invention be
Servo motor, running track are controlled by equipment central industrial control computer according to the signal feedback of sensor in operational process；It is soft
Scraper 8 is the scraper of bone-free bar shaped state made of rubber material, and rubber material is not easy to encircle curved influence without rigidity in installation process
