Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy powder processing, in particular to an aluminum alloy powder processing device. Background Art

[0002] The molding equipment used in the processing of aluminum alloy powder is usually called a powder metallurgy molding machine or a powder forming machine. This equipment is mainly used to press aluminum alloy powder into preformed blanks of the desired shape under pressure, and then carry out subsequent processes such as sintering and heat treatment. Aluminum powder molding equipment is a kind of equipment specially used to process aluminum alloy powder into the desired shape, which usually includes the following main parts: feeding system: used to evenly feed aluminum powder into the molding cavity, molding cavity: a closed space where aluminum powder is placed and compressed into the desired shape by applying pressure, pressure system: usually driven by hydraulic or mechanical means, used to apply high pressure in the molding cavity to make the aluminum powder particles closely combined to form a solid block or aluminum product of a specific shape, mold: a mold designed according to the shape of the desired product, used to manufacture aluminum powder in the molding process, control system: used to monitor and adjust various parameters in the molding process, such as pressure, temperature and time, to ensure product quality.

[0003] The molding equipment used in traditional aluminum alloy powder processing often ejects the material and demolds the material through the stamping ejector installed at the bottom of the mold after the powder is stamped and formed. The ejection structure at the bottom of the mold will cause the bottom of the mold to be non-planar. Therefore, after the powder is stamped and formed, the bottom of the block material will be uneven or defective. At the same time, when the stamping equipment is stamping the powder into blocks, the stamping head of the stamping equipment cannot be completely fitted with the inner wall of the mold (such as product accuracy, temperature and wear of stamping parts). Therefore, after stamping, there will be burr defects on the top of the material, which affects the product appearance and performance. In order to repair these defects, the company may need to invest more manpower, material resources and time for subsequent processing, such as grinding and trimming, which not only increases production costs, but also requires extending the production cycle of the product.

[0004] Therefore, those skilled in the art provide an aluminum alloy powder processing device to solve the problems raised in the above background technology. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the present invention provides an aluminum alloy powder processing and handling device, which is equipped with a unloading component. After the aluminum powder inside the filling tube is stamped into shape, the unloading block is flipped. Due to gravity, the counterweight ring will drive the filling tube to slide downward quickly. When the surface of the counterweight ring slides to the inner wall of the slide groove and cannot slide, the aluminum block formed inside the filling tube will automatically fall down due to vibration. This aluminum block discharging method avoids damage to the surface of the aluminum block by traditional pop-up parts, and also avoids the situation where burrs and defects are easily present on the bottom of the aluminum block, thereby improving the overall quality of the product. After the formed aluminum block falls into the metal grinding disk, the burrs on the upper surface of the aluminum block generated during stamping can be automatically polished, making the product surface smoother, etc., which solves the problem of burr defects on the upper and lower surfaces of the material after the traditional aluminum alloy powder processing device stamps out the aluminum alloy powder.

[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides an aluminum alloy powder processing device, which has the following beneficial effects:

[0021] 1. The aluminum alloy powder processing device is provided with a discharging component. After the aluminum powder inside the filling tube is stamped and formed, the discharging block is turned over. Due to gravity, the counterweight ring will drive the filling tube to slide downward quickly. When the surface of the counterweight ring slides to the inner wall of the slide groove and cannot slide, the aluminum block formed inside the filling tube will automatically fall down due to vibration. This aluminum block discharging method avoids damage to the surface of the aluminum block caused by traditional ejection parts, and also avoids the situation where burrs and defects are easy to exist on the bottom of the aluminum block, thereby improving the overall quality of the product.

[0022] 2. The aluminum alloy powder processing device is provided with a grinding component. After the formed aluminum block falls into the metal grinding disc, the upper surface of the aluminum block fits with the surface of the metal grinding disc during stamping. Through the high-speed rotation of the metal grinding disc, the burrs on the upper surface of the aluminum block generated during stamping can be automatically polished, making the product surface smoother. When the metal grinding disc rotates at a high speed, due to gravity, the counterweight block drives the rotating rod to rotate through the tooth plate, and makes the surface of the rubber plate abut against the surface of the aluminum block, which can enhance the friction between the aluminum block and the metal grinding disc and improve the grinding efficiency.

[0023] 3. The aluminum alloy powder processing device is provided with a clamping block and a positioning groove. Before the aluminum block falls into the placement groove, the counterweight block will not slide due to the abutment with the counterweight block. When the aluminum block enters the placement groove, the pressure of the aluminum block on the clamping block drives the clamping block to leave the positioning groove, so that the aluminum block will not be blocked by the tooth plate and can smoothly enter the placement groove.

The unloading component 4, after the aluminum powder inside the filling tube 45 is stamped into shape, the unloading block 43 is flipped over. Due to gravity, the counterweight ring 451 will drive the filling tube 45 to slide downward quickly. When the surface of the counterweight ring 451 slides to the inner wall of the slide groove 44 and cannot slide, the aluminum block formed inside the filling tube 45 will automatically fall down due to vibration. This aluminum block discharging method avoids damage to the surface of the aluminum block caused by traditional pop-up parts, and also avoids the situation where burrs and defects are easily present on the bottom of the aluminum block, thereby improving the overall quality of the product.

[0039] A counterweight ring 451 is fixedly sleeved on the outer surface of the stuffing tube 45, and steel balls 452 are movably installed equidistantly inside the counterweight ring 451. The surface of the steel balls 452 is rollingly connected to the inner wall of the slide groove 44.

[0041] The surface of the driving gear 48 is meshedly connected to the surface of the driven gear 46 , and the inner bottom end of the unloading assembly 4 is connected to the inside of the discharge chute 5 , so that the formed material can fall into the inside of the discharge chute 5 and be transported out through the transmission belt 6 .

[0042] Embodiment 2

[0043] See also Figure 1-10A grinding assembly 7 is installed inside the stamping base 2 between the discharge trough 5 and the discharge assembly 4. The grinding assembly 7 includes a gear box 71 fixedly installed inside the stamping base 2. The output end of the gear box 71 is rotatably connected to a transition gear 72. The output end of the gear box 71 is rotatably connected to a rotating shaft 73. A positioning bearing 74 is fixedly installed on the outer surface of the rotating shaft 73. The outer ring of the positioning bearing 74 is fixedly connected to the inside of the stamping base 2. A rotating block 75 is fixedly connected to the end surface of the rotating shaft 73. A placement groove 76 is provided at the top and bottom of the rotating block 75. A self-locking stepper motor 77 is fixedly installed at the inner center of the rotating block 75. Both output ends of the self-locking stepper motor 77 are fixedly connected to metal grinding discs 78. Grooves 79 are provided on both side walls of the interior of the rotating block 75. A positioning assembly is installed inside the groove 79. 710, the interior of the rotating block 75 is longitudinally slidably connected with a counterweight block 711, and the surface of the counterweight block 711 is fixedly connected with a tooth plate 712. The top and bottom of the rotating block 75 are both provided with exhaust holes 713. By setting the grinding component 7, after the formed aluminum block falls into the metal grinding disk 78, the upper surface of the aluminum block fits with the surface of the metal grinding disk 78 during stamping. Through the high-speed rotation of the metal grinding disk 78, the burrs on the upper surface of the aluminum block generated during stamping can be automatically polished, making the product surface smoother. When the metal grinding disk 78 rotates at a high speed, due to gravity, the counterweight block 711 drives the rotating rod 7102 to rotate through the tooth plate 712, and makes the surface of the rubber plate 7105 abut against the surface of the aluminum block, which can enhance the friction between the aluminum block and the metal grinding disk 78 and improve the grinding efficiency.

[0044] The positioning assembly 710 includes a fixed bearing 7101 fixedly installed inside the rotating block 75, the inner ring of the fixed bearing 7101 is fixedly connected to a rotating rod 7102, the end face of the rotating rod 7102 is fixedly connected to a toothed disk 7103, the outer surface of the rotating rod 7102 is fixedly connected to a resistance plate 7104, and the end face of the resistance plate 7104 is fixedly connected to a rubber plate 7105. By setting the positioning assembly 710, a certain pressure can be applied to the surface of the material.

[0045] The tooth plate 712 is internally slidably connected with a clamping block 7121, the end face of the clamping block 7121 is fixedly connected to a limiting plate 7122, the surface of the limiting plate 7122 is fixedly mounted with a spring 7123, the outer surface of the limiting plate 7122 is slidably connected to the inside of the tooth plate 712, the surface of the clamping block 7121 extends away from the limiting plate 7122 to the outer surface of the tooth plate 712, the top of the clamping block 7121 is arc-shaped, a positioning groove 751 is provided inside the rotating block 75, and the tooth plate 712 can be slidably positioned by clamping the clamping block 7121 with the positioning groove 75.

[0046] The clamping block 7121 matches the positioning groove 751, and the inside of the counterweight block 711 is equidistantly and movably installed with ball bearings 7111. The surface of the ball bearings 7111 extends to the outer surface of the counterweight block 711, and the surface of the ball bearings 7111 is rollingly connected to the inside of the rotating block 75. By setting the ball bearings 7111, the counterweight block 711 can slide more smoothly and reduce sliding friction.

[0047] The surface of the transition gear 72 is meshedly connected to the surface of the driving gear 48. Driven by the self-locking driving motor 47, when the main shaft 42 rotates a quarter turn, the rotating shaft 73 rotates half a turn, ensuring that each time the formed material falls, it can enter the placement groove 76.

[0048] The surface of the tooth plate 712 is meshedly connected to the surface of the toothed disc 7103 , and the outer surface of the abutment plate 7104 is rotatably connected to the inside of the groove 79 . By providing the groove 79 , the abutment plate 7104 can be accommodated.

[0049] In summary, when the aluminum alloy powder processing device is used, after the aluminum powder is filled into the filling cylinder 45, the punch head on the aluminum powder molding machine body 1 is inserted into the filling cylinder 45 to punch the powder into blocks. After the punching is formed, the punch head is retracted, and the self-locking drive motor 47 is started, and the main shaft 42 is driven to rotate through the driving gear 48 and the driven gear 46. At this time, the unloading block 43 rotates ninety degrees, and the filling cylinder 45 filled with the material is in a horizontal state with the workbench. Then, after the aluminum powder is filled into the filling cylinder 45 again, the punch head on the aluminum powder molding machine body 1 is inserted into the filling cylinder 45 to punch the powder into blocks. The punch head goes deep into the filling tube 45 and punches the powder into blocks. After the punching and forming, the punch head retracts, and then the self-locking drive motor 47 is started again. At this time, the discharge block 43 continues to rotate 90 degrees. At the same time, the material formed by the first punching and forming falls into the placement groove 76 due to gravity. During the falling process inside the driven gear 46, the material will hit the block 7121. The pressure of the aluminum block on the block 7121 drives the block 7121 to slide into the tooth plate 712 and leave the positioning groove 751. At this time, the gravity of the counterweight block 711 drives the tooth plate 712 to slide downward. The toothed plate 712 meshes with the toothed disc 7103, driving the toothed disc 7103 and the rotating rod 7102 to rotate, so that the abutment plate 7104 abuts against the surface of the material through the rubber plate 7105, and then the self-locking stepper motor 77 is started to drive the metal grinding disc 78 to rotate at a high speed, so that the counterweight block 711 can prevent the aluminum block from being blocked by the toothed plate 712, and can automatically grind the burrs on the upper surface of the aluminum block generated during stamping, so that the surface of the product is smoother, and when the metal grinding disc 78 rotates at a high speed, due to gravity, the counterweight block 711 drives the rotating rod 7104 through the toothed plate 712 02 rotates and makes the surface of the rubber plate 7105 rest against the surface of the aluminum block, which can enhance the friction between the aluminum block and the metal grinding disc 78 and improve the grinding efficiency. When the unloading block 43 flips over to load the material again, the rotating block 75 will also rotate one hundred and eighty degrees, so that the polished material can fall on the surface of the transmission belt 6 and be sent out. When the rotating block 75 flips over, due to gravity, the counterweight block 711 rotates in the opposite direction, and the abutment plate 7104 rotates to the inside of the groove 79. At the same time, the surface of the clamping block 7121 will also be clamped in the positioning groove 751, waiting for the next formed material to fall into the placement groove 76.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
