Technical Field

[0002] Aluminum-based composite materials are high-performance materials made with aluminum or aluminum alloy as the matrix and reinforced by adding reinforcing phases (such as particles, whiskers, fibers, etc.). Because they combine the good electrical conductivity, thermal conductivity, and processability of the metal matrix with the high strength, high modulus, and low density of the reinforcing phase, they have been widely used in aerospace, automobile manufacturing, electronic equipment heat dissipation and other fields.

[0003] Compression molding is one of the important molding processes for aluminum-based composite materials. This process applies pressure to the evenly mixed aluminum-based composite material powder to densify it in the mold, and finally forms parts with specific shapes and performances. Compared with other molding methods, compression molding can precisely control the size and shape of the product, and has higher production efficiency, making it suitable for large-scale industrial production.

[0004] When stamping aluminum-based composite material powder, valves are generally used to control the release of a certain amount of powder. Some of the powder added to the molding die tends to adhere to the inner wall of the mold, resulting in uneven distribution of powder inside the mold and affecting the pressing effect. After the pressing is completed, it is necessary to wait for the punch head to separate from the mold and then manually remove the powder molding, which is inefficient and difficult to meet the needs of continuous operation.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The embodiment of the invention discloses an aluminum-based composite material powder continuous molding press with an automatic powder feeding function.

[0023] Example 1 Reference Figure 1-7, which is the first embodiment of the present invention, provides an aluminum-based composite material powder continuous molding press with an automatic powder feeding function, the aluminum-based composite material powder continuous molding press with an automatic powder feeding function includes a main base 1, a pressing mold 2 is fixedly installed in the main base 1, a punching head 3 driven by a punching mechanism is also provided on the main base 1, and a mixing mechanism for mixing the powder in the pressing mold 2 is provided in the main base 1, and a demolding mechanism for demolding is provided in the pressing mold 2. The main base 1 is also provided with a powder feeding mechanism and a discharge mechanism for feeding and discharge, the mixing mechanism includes a guide platform 4 fixedly installed at the bottom end of the pressing mold 2, a guide slider 5 driven by a lifting drive member is slidably connected to the guide platform 4, and vertically distributed spherical hammer rods 6 are fixedly installed in the guide sliders 5, and the spherical hammer rods 6 are distributed in a ring array around the pressing mold 2 through the guide sliders 5, and the lifting drive member includes a column 7 fixedly installed at the bottom of the guide platform 4, and a lifting slide is slidably connected to the column 7 When the lifting slide 8 slides in the lifting groove 701 of the column 7, the guide slide 5 is driven to move synchronously through the connecting rod 801, thereby causing the spherical hammer rods 6 distributed in the ring array to knock and mix the powder in the pressing mold 2.

[0024] The lifting drive also includes a guide column 9 vertically distributed in the main base 1, and the end of the synchronization rod 802 away from the lifting slide 8 is sleeved on the outside of the guide column 9. A return spring 10 is also sleeved outside the guide column 9 and below the synchronization rod 802. The return spring 10 can provide elastic support for the synchronization rod 802, but is still in an incompletely extended state. The cooperation between the guide column 9 and the return spring 10 ensures that the lifting slide 8 can automatically reset after completing the mixing action, preparing for the next mixing cycle.

[0025] The demoulding mechanism includes a demoulding plate 11 that is clearance-matched with the pressing mold 2, and the demoulding plate 11 is provided with symmetrically distributed positioning columns 1101. The main base 1 is respectively movably connected with a first U-shaped pull rod 12 and a second pull rod 13. The positioning column 1101 extends to one end outside the punching head 3 and is provided with a limiting slot 1102 for limiting the sliding of the first pull rod 12 and the second pull rod 13. The demoulding plate 11 is clearance-matched with the pressing mold 2. After the pressing is completed, the first pull rod 12 and the second pull rod 13 cooperate with the limiting slot 1102 of the positioning column 1101 on the demoulding plate 11 to achieve precise pulling of the demoulding plate 11. When the punching head 3 completes the pressing and rises, the first pull rod 12 and the second pull rod 13 can slide along the slide rod 14 under external drive, pulling the demoulding plate 11 to push the molded object out of the pressing mold 2. No manual operation is required, which greatly improves the demoulding efficiency and meets the continuous operation requirements.

[0026] The first pull rod 12 and the second pull rod 13 are both provided with a retaining ring at one end extending outside the main base 1, and the first pull rod 12 and the second pull rod 13 are both connected to the corresponding slide rod 14 through the retaining ring. The end of the first pull rod 12 located in the middle of the main base 1 is sleeved on the guide column 9 and is located above the synchronization rod 802. The first pull rod 12 and the second pull rod 13 cooperate with the slide rod 14 through the retaining ring to ensure that they always move in the vertical direction. When the first pull rod 12 descends, it can slide along the guide column 9 and squeeze the synchronization rod 802 so that the lifting slide 8 and the first pull rod 12 descend synchronously.

[0027] The stamping mechanism includes a hydraulic platform 15 fixedly mounted on the main base 1, and the hydraulic platform 15 is distributed parallel to the main base 1 through a slide rod 14. A stamping push rod 16 is fixedly mounted on the hydraulic platform 15, and the piston rod in the stamping push rod 16 passes through one end of the hydraulic platform 15 and is fixedly connected to a stamping seat 17 for assembling the stamping head 3, and the stamping seat 17 is slidably connected to the slide rod 14 and is located above the retaining ring portion. The hydraulic platform 15 is fixedly mounted on the main base 1 through the slide rod 14 and provides a stable installation foundation for the stamping push rod 16. The piston rod of the stamping push rod 16 drives the stamping seat 17 to slide up and down along the slide rod 14. The stamping head 3 assembled on the stamping seat 17 can stamp and form the powder in the pressing mold 2, and the stamping seat 17 can slide on the slide rod 14, which also ensures the linearity and stability of the movement of the stamping head 3.

[0028] A downwardly inclined material discharge chute 101 is fixedly installed on the main base 1, and symmetrically distributed material guide rails 102 are also fixedly installed on the main base 1. An upwardly inclined powder feeding pipe 201 is provided on the pressing mold 2. The material guide rails 102 are horizontally distributed on the main base 1 and avoid each other with the pressing mold 2.

[0029] The powder feeding mechanism includes a powder storage tank 18 fixedly mounted on the main base 1, and the powder storage tank 18 is connected to the pressing mold 2 through a powder feeding pipe 201. The powder storage tank 18 is also provided with an electronic discharge valve 1801 for controlling the on-off of the powder feeding pipe 201. The powder storage tank 18 stores aluminum-based composite material powder. The electronic discharge valve 1801 accurately controls the on-off of the powder feeding pipe 201 to achieve quantitative powder feeding. The upward-tilted powder feeding pipe 201 uses gravity to assist powder transportation, reducing powder residue in the pipeline.

[0030] The unloading mechanism includes a unloading push rod 19 symmetrically distributed on the side of the main base 1 away from the unloading trough 101, and the piston rod of the unloading push rod 19 is fixedly connected to the unloading seat 20, and the unloading seat 20 is slidably connected to the guide rail 102, and the unloading seat 20 is also provided with an arc groove adapted to the punch head 3. The unloading push rod 19 drives the unloading seat 20 to slide along the guide rail 102. The arc groove on the unloading seat 20 adapted to the punch head 3 can receive the formed object after demolding, and realize automatic unloading through the inclined unloading trough 101.

[0031] During the aluminum-based composite material powder molding process using the device, the aluminum-based composite material powder is first stored in the powder storage tank 18. The electronic discharge valve 1801 accurately controls the on-off of the powder feeding pipe 201 according to the set program. After the valve is opened, the powder feeding pipe 201 is tilted upwards and the powder is smoothly transported to the pressing die 2 under the action of gravity, thereby achieving quantitative powder feeding, avoiding blockage and reducing residue. When the powder enters the pressing die 2, the lifting drive starts to work. The lifting slide 8 on the column 7 slides along the lifting groove 701 under external power or specific program control, and drives the guide slider 5 to slide in the guide platform 4 through the connecting rod 801. Since the guide sliders 5 are arranged in a ring array around the pressing die 2, and each guide slider 5 is fixed with a spherical hammer rod 6, as the guide slider 5 moves, the spherical hammer rod 6 knocks and mixes the powder in the die, improving the powder fluidity and ensuring that the powder is evenly distributed in the die. After the mixing is completed, the lifting slide 8 has a tendency to automatically return to its original position under the action of the guide column 9 and the return spring 10. The hydraulic platform 15 provides stable support for the punch push rod 16. The piston rod of the punch push rod 16 drives the punch seat 17 to slide downward along the slide rod 14, driving the punch head 3 to apply pressure to the evenly mixed powder in the pressing die 2. The precise pressure control is achieved through hydraulic drive, so that the powder is densified in the die and the stamping process is completed. The sliding of the punch seat 17 on the slide rod 14 ensures the linearity and stability of the movement of the punch head 3, ensuring the pressing effect. After the stamping is completed, the punching head 3 rises and resets. At this time, the return spring 10 releases the pressure, resumes its extension and pushes the first pull rod 12 to rise through the synchronization rod 802. The first pull rod 12 and the second pull rod 13 make it slide along the slide rod 14. Since the first pull rod 12 and the second pull rod 13 cooperate with the limiting groove 1102 of the positioning column 1101 on the stripping plate 11, the stripping plate 11 is pulled to push the molded object out of the pressing mold 2. The first pull rod 12 and the second pull rod 13 cooperate with the slide rod 14 through the retaining ring part to ensure the stability of the pulling process, realize automatic demoulding, and improve efficiency. In this process, the first pull rod 12 and the second pull rod 13 can only complete the lifting of the stripping plate 11 through the positioning column 1101 when they are in the rising state. At this time, the first pull rod 12 releases the pressure on the synchronization rod 802, and the return spring 10 pushes the synchronization rod 802 to slide along the guide column 9, and the lifting slide 8 automatically resets; After demolding, the molded object is pushed out of the pressing mold 2 by the demolding plate 11. The arc groove on the unloading seat 20 that is compatible with the punch head 3 can stably support the molded object. The unloading push rod 19 drives the unloading seat 20 to slide along the guide rail 102, and transports the molded object to the unloading trough 101 set downwardly inclined. Using the action of gravity, the molded object automatically slides out along the unloading trough 101, completing the unloading process and realizing continuous operation.
