Description

Technical Field

[0001] The present invention relates to the technical field of powder metallurgy, in particular to a metal powder compacting machine. Background Art

[0002] Metal powder pressing is a process of processing metal powder into a blank or part with a certain shape and density through pressure. It is one of the basic processes in powder metallurgy. It involves selecting suitable metal powder, determining the chemical composition, particle size distribution, particle shape and other characteristics of the powder according to product requirements, and performing pretreatment on the powder, such as drying, screening, and mixing, to ensure the quality and uniformity of the powder. At room temperature, a mechanical press or hydraulic press is used to form the loose powder in a steel mold into a compact at a certain specific pressure. This method is the most widely used and most extensive.

[0003] After the existing metal powder is pressed and formed, the metal workpiece mold that needs to be pressed may have complex positions, and the metal powder may be difficult to completely fill the complex positions of the metal workpiece mold after entering the complex positions of the metal workpiece mold. After a single pressing, it is easy to cause the metal powder pressing effect to be substandard, thereby causing waste of metal powder material. At the same time, the metal powder accumulates to form a stacking layer after entering the mold, and the small cavities that may exist in the stacking layer may interfere with the pressing effect of the metal powder. Therefore, the present application provides a metal powder pressing and forming machine to meet the needs. Summary of the Invention

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above scheme, by setting a pressing component, the rotational cooperation between the closed baffle, the ratchet gear group and the arc-shaped rack group is utilized to realize the reciprocating rotation effect of the closed baffle, and the reciprocating opening and closing of the closed baffle is used to realize the secondary infusion and replenishment of the metal powder in the pressing box. By performing a secondary replenishment on the complex metal workpiece after the initial pressing in the pressing box, the metal powder is replenished and pressed for the second time after the metal powder is pressed for the first time, so as to avoid the metal powder at some complex positions of the metal workpiece from being insufficiently filled, thereby avoiding the metal powder at some complex positions of the metal workpiece from being difficult to be completely pressed and formed. By performing a secondary replenishment of the metal workpiece after the initial pressing, the forming effect after the metal powder is pressed is improved, thereby ensuring the yield rate during the metal powder pressing process, and at the same time reducing the material waste caused by the insufficient pressing of the metal powder, and reducing the use cost of the metal powder during the pressing process. At the same time, by setting multiple groups of pressing boxes, and through the rotational cooperation with the rotating base, the metal powder in the multiple groups of pressing boxes can be cyclically replenished and pressed, thereby improving the processing and pressing efficiency of the metal powder.

[0019] By setting up a vibration component, through the linkage between the gear ring 1, the flat gear 1 and the eccentric wheel, the rotating base is used to drive the force of multiple groups of pressing boxes for cyclic processing, so that the eccentric wheel rotates to hit the impact rod, and the vibration generated by the vibration bracket and the spring pair is transmitted and utilized, and the vibration effect is applied to the surface of the pressing box by the vibration rod, and the metal powder entering the pressing box is vibrated to improve the flatness and fullness of the metal powder after entering the pressing box. When the metal powder is pressed and formed, the presence of small cavities in the metal powder deposit is avoided, and the metal powder is prevented from collapsing during pressing, thereby further ensuring the pressing effect of the metal powder. At the same time, the secondary replenishment step of the metal powder is adapted synchronously to ensure that the metal powder always remains flat and full in the pressing box, thereby realizing a virtuous cycle of the metal powder during the secondary replenishment.

[0020] By setting up a blanking component and utilizing the linkage of the second gear ring and the second flat gear, the rotating blanking effect of the rotating tube is realized. At the same time, the force of the electric push rod is utilized to push the rotating tube into the pressing box. Through the elastic cooperation between the trigger rod, the second spring and the wedge block, the rotation and opening of multiple sets of rotating plates are realized. At the same time, in conjunction with the rotating blanking effect of the rotating tube, when the rotating tube is performing a blanking process on the metal powder, the metal powder falling through the rotating tube is broken up and mixed by the multiple sets of rotating plates, so that the metal powder can be fully and evenly mixed before the pressing begins, avoiding the accumulation of metal powder in the pressing box to form an accumulation layer, further ensuring the pressing and molding effect of the metal powder, and in conjunction with the effect of the pressing component, the secondary replenishment of metal powder in the pressing box is realized, thereby improving the pressing processing redundancy at complex positions of the metal workpiece.

[0045] like Figures 1 to 15As shown, an embodiment of the present invention provides a metal powder pressing molding machine, including an equipment box 1, a control module 2 is installed on the surface of the equipment box 1, a motor 3 is installed at the bottom of the equipment box 1, a rotating base 4 is nested at the bottom of the inner wall of the equipment box 1, and the part of the rotating base 4 extending from the bottom of the equipment box 1 is connected to the motor 3, a storage barrel 5 is nested at the top of the equipment box 1, a mounting bracket 6 is installed at the top of the inner wall of the equipment box 1, and multiple groups of powder pumps 7 are installed on the top of the mounting bracket 6, and the tops of the multiple groups of powder pumps 7 are connected to the bottom of the storage barrel 5, multiple groups of pressing equipment 8 are installed on the top of the rotating base 4, a pressing component 9 is installed at the top edge of the rotating base 4, and the pressing component 9 is used to press and mold metal powder, a vibration component 10 is installed at the top of the rotating base 4, and the vibration component 10 is used to vibrate the metal powder in the pressing component 9, and a blanking component 11 is installed at the bottom edge of the mounting bracket 6, and the blanking component 11 is used to replenish metal powder into the pressing component 9, the vibration component 10 is located on one side of the pressing component 9, and the blanking component 11 is located at the top of the pressing component 9.

[0046] By setting up the pressing component 9, the metal powder is supplemented and pressed for the second time after the metal powder is pressed for the first time, so as to avoid the metal powder at some complex positions of the metal workpiece from being insufficiently filled, thereby avoiding the metal powder at some complex positions of the metal workpiece from being difficult to be completely pressed and formed. By setting up the vibration component 10, the vibration effect is applied to the surface of the pressing box 91 by the vibration rod 10, and the metal powder entering the pressing box 91 is vibrated to improve the flatness and fullness of the metal powder after entering the pressing box 91. By setting up the blanking component 11, the metal powder falling through the rotating tube 113 is broken up and mixed by multiple groups of rotating plates 1112, so that the metal powder can be fully mixed before starting to press, so as to avoid the metal powder from accumulating to form a stacking layer in the pressing box 91.

[0047] like Figures 4 to 8 As shown, the pressing component 9 includes a pressing box 91, and the number of pressing boxes 91 is set to multiple groups. Multiple groups of pressing boxes 91 are installed at the top of the rotating base 4 in a circular array with equal angles. A protective shell 92 is provided on the surface of the pressing box 91, and an arc track 93 is installed on the top of the pressing box 91. A closed baffle 94 is installed on one side of the pressing box 91. The raised position of the edge of the closed baffle 94 contacts the inner wall of the arc track 93. A ratchet gear set 95 is provided on the surface of the columnar part on one side of the closed baffle 94. The ratchet teeth of the two ratchet gears in the ratchet gear set 95 are set in opposite directions. The ratchet gear sets 95 are all meshed with the arc rack sets 96. The arc rack sets 96 are all installed on the inner wall of the equipment box 1, and the number of arc rack sets 96 is set to two groups.

[0048] Then, the control module 2 controls the motor 3 to start, and after the motor 3 is started, it drives the rotating base 4 to rotate synchronously. When the rotating base 4 rotates, it drives the group of pressing boxes 91 to rotate 90 degrees. When the rotating base 4 drives the group of pressing boxes 91 to rotate, the group of pressing boxes 91 drives one of the ratchet gears in the ratchet gear set 95 to pass through and mesh with one of the arc racks in one of the groups of arc rack sets 96. Under the meshing action of the arc racks, one of the ratchet gears in one of the groups of ratchet gear sets 95 is rotated. When one of the ratchet gears in one of the groups of ratchet gear sets 95 rotates, it drives the closing baffle 94 to rotate synchronously, so that the closing baffle 94 rotates along the direction of the circular arc track 93. When the closing baffle 94 rotates, it approaches the top opening position of the pressing box 91 and blocks the top opening position of the pressing box 91 through the closing baffle 94. Then, the control module 2 controls the pressing device 8 at the bottom end of the group of pressing boxes 91 to start, and presses the metal powder in the group of pressing boxes 91 through the pressing device 8;

[0049] Similarly, when the rotating base 4 rotates 90 degrees, one group of pressing boxes 91 rotates and changes its position, so that one group of pressing boxes 91 is located at the bottom end of the discharge tube 117. While the rotating base 4 drives one group of pressing boxes 91 to rotate, one group of pressing boxes 91 drives another ratchet gear in the ratchet gear set 95 to pass through and mesh with another arcuate rack in one group of arcuate rack sets 96. Under the meshing action of the arcuate racks, the other ratchet gear in the ratchet gear set 95 rotates, and while the other ratchet gear in the ratchet gear set 95 rotates, it drives The closed baffle 94 at the top of one group of pressing boxes 91 rotates synchronously, so that the closed baffle 94 rotates along the arc track 93 at the top of one group of pressing boxes 91. While rotating, the closed baffle 94 moves away from the top opening position of one group of pressing boxes 91. Then, the control module 2 controls the motor 3 to start, and the discharge pipe 117 is sent into the internal cavity of one group of pressing boxes 91 to complete the pouring operation of the metal powder in one group of pressing boxes 91. The rotating plate 1112 at the bottom end of the discharge pipe 117 is used to complete the dispersion and mixing of the falling metal powder.

[0050] Similarly, when the metal powder in this set of pressing boxes 91 is pressed and formed, rotate the base 4 by another 90 degrees to rotate and change the position of the pressing box 91 after the first pressing of the metal powder, so that this set of pressing boxes 91 reaches the bottom end of another set of electric push rods 110. During this process, another ratchet gear in the ratchet gear set 95 of the pressing box 91 passes through and meshes with another arc-shaped rack in another set of arc-shaped rack sets 96. Under the meshing action of the arc-shaped rack, another ratchet gear in the ratchet gear set 95 rotates. While the other ratchet gear in the ratchet gear set 95 rotates, it drives the closing baffle 94 at the top of this set of pressing boxes 91 to rotate synchronously, so that the closing baffle 94 rotates along the arc track 93 at the top of this set of pressing boxes 91. While the closing baffle 94 rotates, it moves away from the top opening position of one of the pressing boxes 91.

[0051] By setting the rotational cooperation among the closing baffle 94, the ratchet gear set 95 and the arc-shaped rack set 96, the reciprocating rotation effect of the closing baffle 94 is achieved. Through the reciprocating opening and closing of the closing baffle 94, the secondary perfusion and replenishment of the metal powder in the pressing box 91 are realized, avoiding the insufficient filling of the metal powder at some complex positions of the metal workpiece.

[0052] As Figures 9 to 11 shown, the vibration assembly 10 includes a first toothed ring 101, the first toothed ring 101 is installed at the bottom end of the mounting bracket 6, a first spur gear 102 meshes with one side of the first toothed ring 101, the number of the first spur gears 102 is set to multiple groups, the multiple groups of first spur gears 102 are installed at the top end of the rotating base 4, eccentric wheels 103 are installed at the top ends of the multiple groups of first spur gears 102. The vibration assembly 10 further includes a vibration bracket 104, the cross-sectional structure of the vibration bracket 104 is set as a "C" - shaped structure, a first spring 105 is installed on the inner wall of the vibration bracket 104, one end of the first spring 105 is elastically connected to the protective shell 92, multiple vibration rods 106 are installed on the inner wall of the vibration bracket 104, the multiple vibration rods 106 are nested and installed on the surface of the protective shell 92, and one end of the vibration rod 106 is in contact with the surface of the pressing box 91. One end of the vibration bracket 104 is installed with an impact rod 107, and the surface of one end of the impact rod 107 is in contact with the eccentric wheel 103.

[0053] When the rotating base 4 rotates 90 degrees, the rotating base 4 drives the multiple sets of flat gears 102 to rotate synchronously. The multiple sets of flat gears 102 engage the gear ring 101 while rotating. Under the action of the gear ring 101, the multiple sets of flat gears 102 rotate. The multiple sets of flat gears 102 drive the eccentric wheel 103 to rotate synchronously while rotating. The eccentric wheel 103 continuously hits the impact rod 107 while rotating. Under the rotation of the eccentric wheel 103, the impact rod 107 vibrates, and through the elastic cooperation between the vibration bracket 104 and the spring 105, the vibration of the impact rod 107 is transmitted to the vibration rod 106. Through the contact effect between the vibration rod 106 and the surface of the pressing box 91, the metal powder inside the pressing box 91 is vibrated, so that the metal powder in the pressing box 91 is fully contacted.

[0054] By setting up a linkage between the gear ring 101, the flat gear 102 and the eccentric wheel 103, the rotating base 4 is used to drive the force of multiple groups of pressing boxes 91 for cyclic processing, so that the eccentric wheel 103 rotates to hit the impact rod 107, and the vibration generated is transmitted and utilized through the vibration bracket 104 and the spring 105, and the vibration effect is applied to the surface of the pressing box 91 through the vibration rod 10, so that the metal powder entering the pressing box 91 is vibrated.

[0055] like Figures 12 to 15 As shown, the blanking component 11 includes an electric push rod 110, and the number of the electric push rods 110 is set to multiple groups. The multiple groups of electric push rods 110 are all installed at the bottom end of the mounting bracket 6. The bottom end of the electric push rod 110 is installed with a mounting frame 111, and a motor 112 is installed on the inner wall of the mounting frame 111. A rotating tube 113 is nested and installed at the bottom end of the inner wall of the mounting frame 111. A gear ring 114 is sleeved on the outer surface of the rotating tube 113. A flat gear 115 is meshed on one side of the rotating tube 113. The flat gear 115 is installed at the bottom end of the motor 112. A collar 116 is nested and installed on the inner wall of the top end of the rotating tube 113. The top end of the collar 116 is connected with a blanking tube 117. One end of the discharge pipe 117 is connected with the powder pump 7, and a trigger rod 118 is nested on the inner wall of the bottom part of the discharge pipe 117. A spring 2 119 is sleeved on the surface of the trigger rod 118. The top of the spring 2 119 is connected to the raised part of the surface of the trigger rod 118, and the bottom end of the spring 2 119 is connected to the inner wall of the bottom part of the discharge pipe 117. The surface of the trigger rod 118 is in contact with a wedge 1110, and the wedge 1110 is nested on the surface of the bottom part of the discharge pipe 117. One end of the wedge 1110 is connected to a connecting rod 1111, and the other end of the connecting rod 1111 is connected to a rotating plate 1112. The rotating plate 1112 is rotatably installed at the bottom end of the bottom part of the discharge pipe 117.

[0056] The operator first controls the electric push rod 110 to start through the control module 2. After the electric push rod 110 is started, it drives the installation frame 111 to slide downward synchronously. While the installation frame 111 slides, it drives the rotating tube 113 to slide downward synchronously. While the rotating tube 113 slides, it approaches the top of the pressing box 91 and enters the internal cavity of the pressing box 91 through the opening at the arc track 93 at the top of the pressing box 91, and makes the trigger rod 118 contact the top surface of the pressing device 8, so that the trigger rod 118 is forced to slide upward, and while the trigger rod 118 slides, it drives the spring 2 119 to contract.

[0057] As the trigger rod 118 slides upward, its surface contacts one end of the wedge 1110. When the trigger rod 118 slides into place, the wedge 1110 slides along the surface of the contracted part of the trigger rod 118. As the wedge 1110 slides, it pulls the connecting rod 1111. The connecting rod 1111 is subjected to force and synchronously pulls one end of the rotating plate 1112, causing the rotating plate 1112 to rotate. As the rotating plate 1112 rotates, one side of the rotating plate 1112 moves away from the surface of the bottom end of the discharge tube 117, and at the same time, multiple groups of rotating plates 1112 rotate and open synchronously.

[0058] Subsequently, the control module 2 controls the motor 112 to start. After the motor 112 starts, it drives the spur gear 2 115 to rotate synchronously. When the spur gear 2 115 rotates, the meshing gear ring 2 114 rotates. Under the rotation of the spur gear 2 115, the gear ring 2 114 drives the rotating tube 113 to rotate synchronously.

[0059] While the rotating tube 113 rotates, the control module 2 controls the powder pump 7 to start. After the powder pump 7 is started, the metal powder stored in the storage barrel 5 is drawn into the rotating tube 113 through the discharge tube 117 and the collar 116, and the metal powder falls along the inner wall of the rotating tube 113 into the internal cavity of the pressing box 91. While the rotating tube 113 rotates, it drives the multiple groups of rotating plates 1112 at the bottom part to rotate synchronously. While the multiple groups of rotating plates 1112 rotate, they break up and mix the falling metal powder to avoid accumulation of metal powder.

[0060] When the metal powder in the internal cavity of this group of pressing boxes 91 is completely poured, the control module 2 controls the powder pump 7 to stop working and starts the electric push rod 110 at the same time. After the electric push rod 110 is started, it drives the mounting frame 111 and the rotating tube 113 to slide upward synchronously, so that the rotating tube 113 leaves the internal cavity of the pressing box 91, and at the same time, the bottom end of the trigger rod 118 is out of contact with the top surface of the pressing device 8, and the spring 2 119 unloads the force and stretches out. When the spring 2 119 stretches out, it drives the trigger rod 118 to slide downward, and the trigger rod 118 slides while contacting the wedge block 1110 to slide. The contracted position of the trigger rod 118 pushes the wedge block 1110 to slide in the opposite direction, and the wedge block 1110 slides in the opposite direction while pushing the connecting rod 1111. The connecting rod 1111 is forced to push one end of the rotating plate 1112, so that the rotating plate 1112 rotates in the opposite direction. When the rotating plate 1112 rotates in the opposite direction, one side surface of the rotating plate 1112 approaches and contacts the bottom part surface of the discharge pipe 117.

[0061] Subsequently, the control module 2 controls another set of electric push rods 110 to start again. After the other set of electric push rods 110 is started, it drives the installation frame 111 to slide downward synchronously. While the installation frame 111 slides, it drives the rotating tube 113 to slide downward synchronously. While the rotating tube 113 slides, it approaches the top of the pressing box 91 and enters the internal cavity of the pressing box 91 through the opening at the circular arc track 93 at the top of the pressing box 91, and makes the trigger rod 118 contact the top surface of the pressing device 8, so that the trigger rod 118 is forced to slide upward, and while the trigger rod 118 slides, it drives the spring 2 119 to contract.

[0062] When the trigger rod 118 slides upward, the surface contacts one end of the wedge block 1110. When the trigger rod 118 slides into place, the wedge block 1110 slides along the surface of the contracted part of the trigger rod 118, and the wedge block 1110 slides while pulling the connecting rod 1111. The connecting rod 1111 is forced to pull one end of the rotating plate 1112 synchronously, causing the rotating plate 1112 to rotate. When the rotating plate 1112 rotates, one side of the rotating plate 1112 moves away from the bottom part of the surface of the discharge tube 117, and at the same time, multiple groups of rotating plates 1112 are synchronously rotated and opened. In this process, the control module 2 controls the pressing assembly 9 to reset. Under the downward sliding action of the pressing assembly 9 and the electric push rod 110, the trigger rod 118 is close to the top of the formed metal workpiece, and the formed metal workpiece is pushed downward in the pressing box 91 through the multiple groups of rotated and opened rotating plates 1112 and the electric push rod 110, so that the top of the formed metal workpiece and the pressing box 91 form a cavity.

[0063] Subsequently, the control module 2 controls the powder pump 7 to start. After the powder pump 7 is started, the metal powder stored in the storage barrel 5 is extracted into the rotating tube 113 through the discharge pipe 117 and the ring 116, and the metal powder is made to fall along the inner wall of the rotating tube 113 into the cavity formed by the inner wall of the pressing box 91 and the top of the metal workpiece. When the rotating tube 113 rotates, it drives the multiple groups of rotating plates 1112 at the bottom part to rotate synchronously. When the multiple groups of rotating plates 1112 rotate, they break up and mix the falling metal powder, thereby realizing secondary replenishment of the metal powder in the pressing box 91.

[0064] When the metal powder in the pressing box 91 is replenished, the rotating base 4 continues to drive the rotation 90 degrees. After the pressing box 91 is rotated into place, the control module 2 controls the pressing device 8 at the bottom end of this group of pressing boxes 91 to start again, and uses the pressing device 8 to perform a secondary pressing process on the replenished metal powder in this group of pressing boxes 91 to complete the pressing process of the metal powder, and after the secondary pressing is completed, the metal workpiece after the secondary pressing is collected and processed.

[0065] By setting the linkage between the second gear ring 114 and the second flat gear 115, the rotating tube 113 can achieve the rotational unloading effect. At the same time, the electric push rod 110 is used to push the rotating tube 113 into the pressing box 91 to realize the rotation and opening of the multiple sets of rotating plates 1112. When the rotating tube 113 unloads the metal powder, the multiple sets of rotating plates 1112 are used to break up and mix the metal powder falling through the rotating tube 113, so that the metal powder can be fully mixed before pressing begins.

[0066] The working principle of the technical solution provided by the present invention is as follows:

[0067] The operator first controls the electric push rod 110 to start through the control module 2. After the electric push rod 110 is started, it drives the installation frame 111 to slide downward synchronously. While the installation frame 111 slides, it drives the rotating tube 113 to slide downward synchronously. While the rotating tube 113 slides, it approaches the top of the pressing box 91 and enters the internal cavity of the pressing box 91 through the opening at the arc track 93 at the top of the pressing box 91, and makes the trigger rod 118 contact the top surface of the pressing device 8, so that the trigger rod 118 is forced to slide upward, and while the trigger rod 118 slides, it drives the spring 2 119 to contract.

[0068] As the trigger rod 118 slides upward, its surface contacts one end of the wedge 1110. When the trigger rod 118 slides into place, the wedge 1110 slides along the surface of the contracted part of the trigger rod 118. As the wedge 1110 slides, it pulls the connecting rod 1111. The connecting rod 1111 is subjected to force and synchronously pulls one end of the rotating plate 1112, causing the rotating plate 1112 to rotate. As the rotating plate 1112 rotates, one side of the rotating plate 1112 moves away from the surface of the bottom end of the discharge tube 117, and at the same time, multiple groups of rotating plates 1112 rotate and open synchronously.

[0069] Subsequently, the control module 2 controls the motor 112 to start. After the motor 112 starts, it drives the spur gear 2 115 to rotate synchronously. When the spur gear 2 115 rotates, the meshing gear ring 2 114 rotates. Under the rotation of the spur gear 2 115, the gear ring 2 114 drives the rotating tube 113 to rotate synchronously.

[0070] While the rotating tube 113 rotates, the control module 2 controls the powder pump 7 to start. After the powder pump 7 is started, the metal powder stored in the storage barrel 5 is drawn into the rotating tube 113 through the discharge tube 117 and the collar 116, and the metal powder falls along the inner wall of the rotating tube 113 into the internal cavity of the pressing box 91. While the rotating tube 113 rotates, it drives the multiple groups of rotating plates 1112 at the bottom part to rotate synchronously. While the multiple groups of rotating plates 1112 rotate, they break up and mix the falling metal powder to avoid accumulation of metal powder.

[0071] When the metal powder in the internal cavity of this group of pressing boxes 91 is completely poured, the control module 2 controls the powder pump 7 to stop working and starts the electric push rod 110 at the same time. After the electric push rod 110 is started, it drives the mounting frame 111 and the rotating tube 113 to slide upward synchronously, so that the rotating tube 113 leaves the internal cavity of the pressing box 91, and at the same time, the bottom end of the trigger rod 118 is out of contact with the top surface of the pressing device 8, and the spring 2 119 unloads the force and stretches out. When the spring 2 119 stretches out, it drives the trigger rod 118 to slide downward, and the trigger rod 118 slides while contacting the wedge block 1110 to slide. The contracted position of the trigger rod 118 pushes the wedge block 1110 to slide in the opposite direction, and the wedge block 1110 slides in the opposite direction while pushing the connecting rod 1111. The connecting rod 1111 is forced to push one end of the rotating plate 1112, so that the rotating plate 1112 rotates in the opposite direction. When the rotating plate 1112 rotates in the opposite direction, one side surface of the rotating plate 1112 approaches and contacts the bottom part surface of the discharge pipe 117.

[0072] Subsequently, the control module 2 controls the motor 3 to start. After the motor 3 is started, it drives the rotating base 4 to rotate synchronously. When the rotating base 4 rotates, it drives the group of pressing boxes 91 to rotate 90 degrees. When the rotating base 4 drives the group of pressing boxes 91 to rotate, the group of pressing boxes 91 drives one of the ratchet gears in the ratchet gear group 95 to pass through and engage with one of the arc racks in one of the groups of arc rack groups 96. Under the meshing action of the arc racks, one of the ratchet gears in one of the groups of ratchet gear groups 95 is rotated. When one of the ratchet gears in one of the groups of ratchet gear groups 95 rotates, it drives the closing baffle 94 to rotate synchronously, so that the closing baffle 94 rotates along the direction of the circular arc track 93. When the closing baffle 94 rotates, it approaches the top opening position of the pressing box 91 and blocks the top opening position of the pressing box 91 through the closing baffle 94. Subsequently, the control module 2 controls the pressing device 8 at the bottom end of the group of pressing boxes 91 to start, and uses the pressing device 8 to press the metal powder in the group of pressing boxes 91.

[0073] Similarly, when the rotating base 4 rotates 90 degrees, one group of pressing boxes 91 rotates and changes its position, so that one group of pressing boxes 91 is located at the bottom end of the discharge tube 117. While the rotating base 4 drives one group of pressing boxes 91 to rotate, one group of pressing boxes 91 drives another ratchet gear in the ratchet gear set 95 to pass through and mesh with another arcuate rack in one group of arcuate rack sets 96. Under the meshing action of the arcuate racks, the other ratchet gear in the ratchet gear set 95 rotates, and while the other ratchet gear in the ratchet gear set 95 rotates, it drives The closed baffle 94 at the top of one group of pressing boxes 91 rotates synchronously, so that the closed baffle 94 rotates along the direction of the arc track 93 at the top of one group of pressing boxes 91, and the closed baffle 94 rotates away from the top opening position of one group of pressing boxes 91. Then the control module 2 controls the motor 3 to start, and sends the discharge pipe 117 into the internal cavity of one group of pressing boxes 91 to complete the pouring operation of the metal powder in one group of pressing boxes 91, and completes the breaking and mixing of the falling metal powder through the rotating plate 1112 at the bottom end of the discharge pipe 117.

[0074] At the same time, when the rotating base 4 rotates 90 degrees, the rotating base 4 drives the multiple sets of flat gears 102 to rotate synchronously. The multiple sets of flat gears 102 engage the gear ring 101 while rotating. Under the action of the gear ring 101, the multiple sets of flat gears 102 rotate. The multiple sets of flat gears 102 drive the eccentric wheel 103 to rotate synchronously while rotating. The eccentric wheel 103 continuously hits the impact rod 107 while rotating. Under the rotation of the eccentric wheel 103, the impact rod 107 vibrates, and through the elastic cooperation between the vibration bracket 104 and the spring 105, the vibration of the impact rod 107 is transmitted to the vibration rod 106. Through the contact effect between the vibration rod 106 and the surface of the pressing box 91, the metal powder inside the pressing box 91 is vibrated, so that the metal powder in the pressing box 91 is fully contacted.

[0075] Similarly, when the metal powder in this group of pressing boxes 91 is pressed into shape, the rotating base 4 continues to rotate 90 degrees, and the pressing box 91 that completes the first pressing of the metal powder is rotated and changed in position, so that this group of pressing boxes 91 reaches the bottom end of another group of electric push rods 110. During this process, the pressing box 91 drives another ratchet gear in the ratchet gear set 95 to pass through and engage with another arc rack in another group of arc rack sets 96. Under the meshing action of the arc racks, the other ratchet gear in the ratchet gear set 95 rotates. While the other ratchet gear in the ratchet gear set 95 rotates, it drives the closed baffle 94 at the top of this group of pressing boxes 91 to rotate synchronously, so that the closed baffle 94 rotates along the direction of the arc track 93 at the top of this group of pressing boxes 91. While the closed baffle 94 rotates, it moves away from the top opening position of one of the groups of pressing boxes 91.

[0076] Subsequently, the control module 2 controls another set of electric push rods 110 to start again. After the other set of electric push rods 110 is started, it drives the installation frame 111 to slide downward synchronously. While the installation frame 111 slides, it drives the rotating tube 113 to slide downward synchronously. While the rotating tube 113 slides, it approaches the top of the pressing box 91 and enters the internal cavity of the pressing box 91 through the opening at the circular arc track 93 at the top of the pressing box 91, and makes the trigger rod 118 contact the top surface of the pressing device 8, so that the trigger rod 118 is forced to slide upward, and while the trigger rod 118 slides, it drives the spring 2 119 to contract.

[0077] When the trigger rod 118 slides upward, the surface contacts one end of the wedge block 1110. When the trigger rod 118 slides into place, the wedge block 1110 slides along the surface of the contracted part of the trigger rod 118, and the wedge block 1110 slides while pulling the connecting rod 1111. The connecting rod 1111 is forced to pull one end of the rotating plate 1112 synchronously, causing the rotating plate 1112 to rotate. When the rotating plate 1112 rotates, one side of the rotating plate 1112 moves away from the bottom part of the surface of the discharge tube 117, and at the same time, multiple groups of rotating plates 1112 are synchronously rotated and opened. In this process, the control module 2 controls the pressing assembly 9 to reset. Under the downward sliding action of the pressing assembly 9 and the electric push rod 110, the trigger rod 118 is close to the top of the formed metal workpiece, and the formed metal workpiece is pushed downward in the pressing box 91 through the multiple groups of rotated and opened rotating plates 1112 and the electric push rod 110, so that the top of the formed metal workpiece and the pressing box 91 form a cavity.

[0078] Subsequently, the control module 2 controls the powder pump 7 to start. After the powder pump 7 is started, the metal powder stored in the storage barrel 5 is extracted into the rotating tube 113 through the discharge pipe 117 and the ring 116, and the metal powder is made to fall along the inner wall of the rotating tube 113 into the cavity formed by the inner wall of the pressing box 91 and the top of the metal workpiece. When the rotating tube 113 rotates, it drives the multiple groups of rotating plates 1112 at the bottom part to rotate synchronously. When the multiple groups of rotating plates 1112 rotate, they break up and mix the falling metal powder, thereby realizing secondary replenishment of the metal powder in the pressing box 91.

[0079] When the metal powder in the pressing box 91 is replenished, the rotating base 4 continues to drive the rotation 90 degrees. After the pressing box 91 is rotated into place, the control module 2 controls the pressing device 8 at the bottom end of this group of pressing boxes 91 to start again, and uses the pressing device 8 to perform a secondary pressing process on the replenished metal powder in this group of pressing boxes 91 to complete the pressing process of the metal powder, and after the secondary pressing is completed, the metal workpiece after the secondary pressing is collected and processed.
