Description

Technical Field

[0001] The present invention relates to the technical field of powder metallurgy, and particularly to a raw material adding device for intelligent heat treatment of powder metallurgy. Background Art

[0002] Powder metallurgy is a manufacturing method in which metal powders are mixed with appropriate additives, the mixture is pressed into the desired shape under high pressure, and then metal parts are made through a sintering process.

[0003] The patent with the application number CN202111397357.4 discloses a raw material adding device for intelligent heat treatment of powder metallurgy, which specifically relates to the technical field of powder metallurgy. It includes a feeding cylinder, one side of the feeding cylinder is fixedly provided with a feeding pipe, the top of the feeding cylinder is fixedly provided with a first motor, a rotating rod is arranged inside the feeding cylinder, a rotating ring is fixedly provided at the outer end of the rotating rod, a plurality of fan blades are fixedly provided at the outer end of the rotating ring, a plurality of stirring rods are fixedly provided at the outer end of the rotating ring, and a plurality of dust suction pipes are fixedly provided at the outer end of the feeding cylinder. By stirring the raw materials with the stirring rods, the present invention can effectively prevent the raw materials from caking, making the raw materials more uniform, and thus making the quality of the processed products better. By sucking the external raw material powder through the dust suction pipes, the situation of external dust floating is avoided, making the processing environment better, and also avoiding the situation that workers' health is affected by inhaling the powder. This device sucks and recovers the floating powder through the rotation of the subsequent fan, but it is difficult to recover all the floating powder and dust only through the rotation of the fan, and there will still be some powder and dust floating, which will have a certain impact on the working environment. Moreover, when a large amount of powder passes through the feeding pipe together, it is easy to cause blockage. Therefore, a raw material adding device for intelligent heat treatment of powder metallurgy is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a raw material adding device for intelligent heat treatment of powder metallurgy in view of the above deficiencies in the prior art.

One end of the telescopic rod away from the pressing rod is slidably connected to the inner wall of the tank body. The powder enters the tank body from the feed pipe and enters the powder metallurgy processing device through the sealed tank body and the discharge pipe at its bottom. Thus, the fully sealed structure can prevent the powder dust from floating out of the device and prevent the working environment from being polluted by dust. At the same time, the motor drives the transmission rod to rotate, the transmission rod drives the scraping rod and the stirring rod on its surface to rotate, and the stirring rod stirs the powder to prevent the powder from accumulating at the discharge pipe at the bottom of the tank body, which in turn affects the normal discharge of the powder. At the same time, the transmission rod drives the pressing rod, which is limited by the telescopic rod and cannot rotate, to reciprocate up and down through the cross-shaped spiral groove opened on its surface. The pressing rod moves down into the discharge pipe and dredges the discharge pipe to prevent the powder from being blocked in the discharge pipe during discharging, which in turn affects the normal feeding of the powder.

At the same time, when the slider rotates, it will drive the guide rod to move in the guide groove, and the guide groove will guide the guide rod and drive the slider to slide on the fixed rod. At this time, the slider will move along the transmission rod in a circular motion while moving on the fixed rod, so as to improve the rolling range of the pressure roller. When the slider slides on the fixed rod, the pressure block in the slider will move with it. The pressure block will drive the top plate to move. The top plate will move in the arc groove at the bottom of the fixed rod. When the top plate moves to the arc groove, the elastic member in the slider will drive the pressure block to move up, so that the top plate tightly adheres to the inner wall of the arc groove. When the top plate crosses the arc groove, it will move to the bottom of the fixed rod. At this time, the top plate will move down and drive the pressure block to move, and the pressure block will further crush the agglomerated powder on the filter plate.

When the two sliders gather, the sliders will contact and push the first slide plate and the second slide plate to gather. The first slide plate and the second slide plate will push the connecting rod on the knocking plate to move downward through two oppositely arranged inclined slots on the surface, causing the knocking plate to also be driven downward and strike on the filter plate, making the filter plate vibrate and promoting the screening of the powder at the top, improving the screening efficiency of the filter plate.

The moving plate will drive the elastic telescopic plate to move downward. The elastic telescopic plate will drive the scraping plate to move on the inner wall of the tank body and scrape off the powder adhering to the inner wall of the tank body, ensuring that the powder can be completely discharged, reducing the powder residue. At the same time, when the stirring rod rotates, it will contact the top of the moving plate and push the moving plate downward through the arc surface at the top of the moving plate. The moving plate will further drive the scraping plate on the elastic telescopic plate to move downward, further improving the scraping effect of the powder on the inner wall of the tank body.

The pressing block 761 further crushes the agglomerated powder on the filter plate 71.

[0018] Working principle: The powder enters the tank body 1 from the feed pipe 6 and enters the powder metallurgy processing device through the sealed tank body 1 and the discharge pipe 3 at its bottom. Thus, the fully sealed structure can prevent the powder dust from floating out of the device and prevent the working environment from being polluted by dust. At the same time, the motor 51 drives the transmission rod 52 to rotate. The transmission rod 52 drives the scraping rod 55 and the stirring rod 56 on its surface to rotate. The stirring rod 56 agitates the powder to prevent the powder from accumulating at the discharge pipe 3 at the bottom of the tank body 1, which in turn affects the normal discharge of the powder.

The pressure rod 53 moves down into the discharge pipe 3 and dredges the discharge pipe 3 to prevent the powder from being blocked in the discharge pipe 3 during discharging, which in turn affects the normal feeding of the powder.

At the same time, when the slider 73 rotates, it drives the guide rod 75 to move in the guide groove 76. The guide groove 76 guides the guide rod 75 and drives the slider 73 to slide on the fixed rod 72. At this time, the slider 73 moves on the fixed rod 72 and makes a circular motion along the transmission rod 52, thereby increasing the rolling range of the pressure roller 74. When the slider 73 slides on the fixed rod 72, the pressing block 761 in the slider 73 moves with it. The pressing block 761 drives the top plate 762 to move. The top plate 762 moves in the arc-shaped groove 763 at the bottom of the fixed rod 72. When the top plate 762 moves to the arc-shaped groove 763, the elastic member in the slider 73 drives the pressing block 761 to move up, so that the top plate 762 tightly adheres to the inner wall of the arc-shaped groove 763. When the top plate 762 crosses the arc-shaped groove 763, it moves to the bottom of the fixed rod 72. At this time, the top plate 762 moves down and drives the pressing block 761 to move, and the pressing block 761 further crushes the agglomerated powder on the filter plate 71.
