Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, specifically to a powder metallurgy processing table for producing automobile cams. Background Technology

[0002] As a key component of the engine, the camshaft of an automobile suffers from low material utilization, complex processing steps, and high costs due to traditional manufacturing processes such as casting and forging. Powder metallurgy, a near-net-shape forming process, can directly manufacture camshaft parts by pressing and sintering metal powder. This not only reduces material waste and subsequent processing but also improves production efficiency and product consistency, thus offering significant advantages in the automotive camshaft manufacturing field. A search revealed that prior art publication number CN221246943U discloses a powder metallurgy processing table, including a processing table with a lower mold and guide pillars at the four corners near the center of the top of the processing table. An upper mold base is fixedly connected to the top of each guide pillar. A hydraulic cylinder is located at the center of the top of the upper mold base, with its output end penetrating the upper mold base and fixedly connected to a fixed plate. A sealing ring is located at the center of the bottom of the fixed plate, and the bottom end of the sealing ring is fixedly connected to the lower mold base. Furthermore, this patent also includes a magnetic strip plate for removing the processed part from the lower mold, which is movably mounted. When the workpiece is ejected from the lower mold, the magnetic strip moves to the lower mold, attracts the workpiece, and then moves the workpiece away from the lower mold, thereby removing the workpiece from the lower mold.

[0003] However, when the device in the aforementioned patent uses a magnet to attract parts, it is easy to attract some metal powder. Over time, the metal powder will coat the magnet, thereby reducing the magnet's attraction and making it less able to attract parts.

[0004] Therefore, existing technologies need further development. Utility Model Content

[0017] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0018] According to an embodiment of this utility model, a powder metallurgy processing table for producing automotive camshafts is provided. Please refer to [link / reference]. Figures 1 to 4 The system includes: a processing table 1; a cam adsorption assembly 2, which is disposed on the processing table 1 and includes an adsorption magnet 21 for adsorbing automotive cams, wherein the adsorbed automotive cam is a pressed automotive cam blank, and the adsorption magnet 21 is movably disposed; and a magnet cleaning assembly 3, which is used to clean the metal powder adsorbed on the adsorption magnet 21, and includes: a cleaning part 31, which is slidably disposed relative to the adsorption magnet 21; and a first electric push rod 32, which is mounted on the processing table 1 and whose moving end is connected to the cleaning part 31.

[0019] By adopting the above technical solution, the magnetic cleaning component 3 cleans the adsorption magnet 21, which solves the problem that metal powder will coat the adsorption magnet 21, thereby reducing the attraction of the adsorption magnet 21 and making it less able to adsorb the camshaft of the car.

[0020] Please refer to Figure 1 and Figure 3 The cleaning unit 31 includes: a connecting block 311, which is fixedly connected to the moving end of the first electric push rod 32; a U-shaped plate 312, which is fixedly connected to the connecting block 311; a scraper 313, which is disposed inside the U-shaped plate 312 and fixed to the U-shaped plate 312; and a brush, which is mounted on the scraper 313 and is slidably disposed relative to the adsorption magnet 21, and the brush abuts against the adsorption magnet 21.

[0021] By adopting the above technical solution, the brush comes into contact with the magnet 21, and then the first electric push rod 32 drives the scraper 313 and the brush to move, thereby scraping and cleaning the surface of the magnet 21, thus achieving the effect of cleaning the magnet 21.

[0022] Please refer to Figure 1 , Figure 2 and Figure 4 The cleaning unit 31 further includes: a ventilation hole 314, which is formed on the scraper 313, and multiple ventilation holes 314 are provided, which are interconnected to form an air duct; a dust suction hole 315, which is formed on the U-shaped plate 312, and the dust suction hole 315 passes through the U-shaped plate 312 and communicates with the air duct; and a vacuum cleaner, which is connected to the dust suction hole 315 and fixed to the processing table 1.

[0023] By adopting the above technical solution, the air duct formed by multiple air holes 314 on the scraper 313 allows the metal powder scraped by the brush to be sucked away by the vacuum cleaner through the air duct, further improving the cleaning effect of the metal powder.

[0024] Please refer to Figure 1 The cam adsorption assembly 2 includes: a second electric push rod 22, which is mounted on the processing table 1; a connecting plate 23, which is fixedly connected to the moving end of the second electric push rod 22, and an adsorption magnet 21 is fixed on the side of the connecting plate 23 away from the second electric push rod 22.

[0025] By adopting the above technical solution, the connecting plate 23 is pushed by the second electric push rod 22 to move the adsorption magnet 21, thereby completing the absorption of the automobile cam blank.

[0026] Please refer to Figure 2 The powder metallurgy processing table 1 further includes: an automotive cam processing assembly 4, which includes: at least two support rods 41, each of which is disposed on the processing table 1 and spaced apart around the edge of the processing table 1; each of which protrudes from the top of the processing table 1; an upper mold base 42, which is fixedly connected to each of the support rods 41; the upper mold base 42 is located at the end of each support rod 41 away from the processing table 1; and a hydraulic rod 4. 3. The hydraulic rod 43 is mounted on the upper mold base 42, with the output end of the hydraulic rod 43 facing the processing table 1 and passing through the upper mold base 42; the lower mold base is located below the upper mold base 42 and is fixedly connected to the output end of the hydraulic rod 43; the lower mold 44 is mounted on the processing table 1; the lower mold 44 is correspondingly arranged with the lower mold base, and the lower mold base is slidably arranged relative to the lower mold 44.

[0027] By adopting the above technical solution, the lower mold base is moved by the output end of the hydraulic rod 43, and the metal powder in the lower mold 44 is pressed into a green car cam through the cooperation between the lower mold base and the lower mold 44.

[0028] Please refer to Figure 1 and Figure 2The powder metallurgy processing table 1 further includes: an automotive cam ejector assembly 5, which includes: a sliding plate 51 located below the upper mold base 42, the sliding plate 51 being movably sleeved on each of the support rods 41 along the height direction; the lower mold base being installed at the bottom of the sliding plate 51, the sliding plate 51 being fixed to the output end of the hydraulic rod 43; a receiving cavity 52, the receiving cavity 52 being opened on the processing table 1 adjacent to the first electric push rod 32; and a connecting frame 53. One end of the connecting frame 53 is fixedly connected to the sliding plate 51, and the other end of the connecting frame 53 is located in the receiving cavity 52; the upper tray 55 is slidably disposed relative to the lower mold 44; the top column 56 is fixedly connected to the upper tray 55 at one end and is slidably disposed relative to the processing table 1; the lower tray 57 is fixed to the other end of the top column 56; the pushing column 58 is fixed to the connecting frame 53 and abuts against the lower tray 57.

[0029] By adopting the above technical solution, while the lower mold base moves upward through the hydraulic rod 43, the sliding plate 51 also moves upward along with the hydraulic rod 43. The sliding plate 51 drives the connecting frame 53 to move upward. At this time, the push column 58 pushes the lower tray 57 to move upward, and then the upper tray 55 pushes out the pressed car cam blank.

[0030] Please refer to Figure 2 There are at least two springs 54, each spring 54 is arranged in a one-to-one correspondence with each of the support rods 41, each spring 54 is sleeved on the corresponding support rod 41, and the two ends of the spring 54 abut against the sliding plate 51 and the upper mold base 42 respectively.

[0031] By adopting the above technical solution, the spring 54 applies a pulling force to the sliding plate 51, which facilitates the acceleration of the retraction speed of the output end of the hydraulic rod 43.

[0032] Please refer to Figure 1 The powder metallurgy processing table 1 further includes: a feeding assembly 6, which includes: a feeding box 61, which is slidably disposed relative to the processing table 1 and located above the lower mold 44. The feeding box 61 is used to replenish metal powder to the lower mold 44; a motor 62, which is fixedly connected to the processing table 1; and a threaded rod, one end of which is rotatably disposed relative to the processing table 1, and the other end of which is fixed to the output shaft of the motor 62. The threaded rod is threadedly connected to the feeding box 61.

[0033] By adopting the above technical solution, the screw rod is driven to rotate by the motor 62, thereby driving the feeding box 61 to move, so that the feeding box 61 can complete the feeding of material to the lower mold 44.

[0034] Working principle: When machining an automotive camshaft is required, motor 62 is first turned on. Motor 62 drives the threaded rod to rotate, thereby moving the feeding box 61 so that the feeding box 61 can feed material into the lower mold 44. Then, hydraulic rod 43 is activated. The output end of hydraulic rod 43 drives the lower mold base to move. Through the cooperation between the lower mold base and the lower mold 44, the metal powder in the lower mold 44 is pressed into an automotive camshaft blank. Then, the second electric push rod 22 is activated. The second electric push rod 22 pushes the connecting plate 23, which moves the adsorption magnet 21 to complete the picking up of the automotive camshaft blank. This process is repeated multiple times. The magnet 21 may have metal powder on it. To prevent the metal powder from affecting the magnetic force of the magnet 21, the first electric push rod 32 is activated. The first electric push rod 32 drives the scraper 313 and the brush to move, thereby scraping and cleaning the surface of the magnet 21. During the movement of the brush, the vacuum cleaner is activated simultaneously. The metal powder is sucked into the vacuum cleaner through the suction hole 315 and the vent hole 314, thereby achieving the effect of cleaning the magnet 21. This avoids the problem that the metal powder will coat the magnet 21, which would reduce the magnetic force of the magnet 21 and make it less able to attract the car cam.
