Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy technology, and in particular to a separation device for powder metallurgy products. Background Technology

[0002] Powder metallurgy is a process technology that involves producing metal powders or using metal powders as raw materials, followed by shaping and sintering to manufacture metallic materials, composite materials, and various types of products. Powder metallurgy shares similarities with ceramic production, both belonging to powder sintering technology; therefore, a range of new powder metallurgy technologies can also be applied to the preparation of ceramic materials. Due to its advantages, powder metallurgy technology has become a key to solving new material problems and plays a crucial role in the development of new materials.

[0003] However, in the existing technology on the market, after the powder metallurgy pressing process in the mold is completed, the workers need to manually remove the processed powder metallurgy products from the mold. This reduces the equipment's demolding efficiency and, due to the long hours of manual work, greatly increases the labor intensity of the workers, thereby significantly reducing the equipment's processing efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a separation device for powder metallurgy products.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a separation device for powder metallurgy products, comprising a box body, a fixing plate fixedly connected to the middle of the inner wall of the box body, a box door hinged to the surface of the box body, a lower mold provided on the top of the fixing plate, hydraulic cylinders symmetrically installed on the top of the inner wall of the box body, a fixing rod keyed to the bottom of the hydraulic cylinder, a pressure plate fixedly connected to the bottom of the fixing rod, an upper mold fixedly connected to the bottom of the pressure plate, and a discharge mechanism symmetrically arranged on the top of the inner wall of the box body.

[0006] As a further description of the above technical solution: The discharge mechanism includes electrically operated telescopic rods symmetrically arranged on the top of the inner wall of the box. A connecting rod is provided at the bottom of the electrically operated telescopic rod, and a connecting rod is detachably connected to the bottom of the connecting rod. The two sides of the lower mold are fixedly connected to the connecting rod.

[0007] As a further description of the above technical solution: The bottom of the connecting rod is rotatably connected to a rotating shaft, the bottom of the rotating shaft is fixedly connected to a threaded block, and the top of the connecting rod is provided with a threaded hole for screwing into the threaded block.

[0008] As a further description of the above technical solution: The electric telescopic rod is fixedly connected to a fixing ring near the top of its outer contour, and the top of the fixing ring is detachably connected to the top of the inner wall of the box.

[0009] As a further description of the above technical solution: The bottom of the fixing ring is provided with fixing bolts arranged in a circular array with the axis of the fixing ring as the center, and the inner wall of the top of the box is provided with screw holes that are compatible with the fixing bolts.

[0010] As a further description of the above technical solution: The pressure plate has symmetrical through holes on both sides, and the connecting rod is connected through the inner cavity of the through hole.

[0011] This utility model has the following beneficial effects: Compared with existing technologies, this powder metallurgy product separation device, through its discharge mechanism, allows the lower mold to be moved upward after the metallurgical raw material is pressed in the lower mold during equipment operation. This facilitates the unloading and unloading of metallurgical products by the operator, thereby improving the processing efficiency of the equipment. Furthermore, the hydraulic cylinder and fixing rod connected by a key can be disassembled and replaced, and the fixing rod, pressure plate, and upper mold can be separated from the connecting rod, making it convenient for the operator to replace the lower and upper molds. This allows the equipment to process different types of metallurgical products, thus increasing the practicality of the equipment. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Reference Figure 1-4 This utility model provides a separation device for powder metallurgy products, including a box body 1, a fixing plate 2 fixedly connected to the middle of the inner wall of the box body 1, a box door 3 hinged to the surface of the box body 1, a lower mold 4 provided on the top of the fixing plate 2, hydraulic cylinders 5 symmetrically installed on the top of the inner wall of the box body 1, a fixing rod 6 keyed to the bottom of the hydraulic cylinder 5, a pressure plate 7 fixedly connected to the bottom of the fixing rod 6, an upper mold 8 fixedly connected to the bottom of the pressure plate 7, a discharge mechanism symmetrically arranged on the top of the inner wall of the box body 1, a placement box 101 slidably connected to the bottom of the inner cavity of the box body 1, a rubber protective pad installed on the inner wall of the placement box 101, sliding rods 102 fixedly connected to both sides of the placement box 101, and sliding grooves adapted to the sliding rods 102 opened on both sides of the inner wall of the box body 1 near the bottom.

[0016] First, the raw material is placed into the lower mold 4. Then, the hydraulic cylinder 5 is activated to move the pressure plate 7 at the bottom of the fixed rod 6 downward, thereby closing the lower mold 4 and the pressure plate 7 to press the metallurgical raw material in the lower mold 4, thus completing the pressing of the metallurgical product. Through the set discharge mechanism, after the equipment has pressed the metallurgical raw material in the lower mold 4, the lower mold 4 can be moved upward during the use of the equipment, making it convenient for the staff to discharge and pick up the metallurgical product, thereby improving the processing efficiency of the equipment. The placement box 101 is pulled outward, causing the placement box 101 to drive the slide rod 102 to move outward in the slide groove opened in the inner wall of the box 1. Then, the processed metallurgical product is placed into the box 1 for temporary storage.

[0017] The discharge mechanism includes an electric telescopic rod 9 symmetrically arranged on the top of the inner wall of the box 1. A connecting rod 10 is provided at the bottom of the electric telescopic rod 9. A connecting rod 11 is detachably connected to the bottom of the connecting rod 10. The two sides of the lower mold 4 are fixedly connected to the connecting rod 11. Through holes 12 are symmetrically opened on both sides of the pressure plate 7. The connecting rod 10 is connected to the inner cavity of the through hole 12. A rotating shaft 13 is rotatably connected to the bottom of the connecting rod 10. A threaded block is fixedly connected to the bottom of the rotating shaft 13. A threaded hole 14 is opened at the top of the connecting rod 11 and screwed to the threaded block.

[0018] After the equipment processes the metallurgical raw materials in the lower mold 4 into metallurgical products, when it is necessary to discharge the material, the electric telescopic rod 9 is activated to drive the connecting rod 10 to move upward, which in turn drives the connecting rod 11 to move upward. Then, the connecting rod 11 drives the lower mold 4 to move upward, thereby separating the lower mold 4 from the metallurgical products processed in the lower mold 4. Afterward, the staff can separate and discharge the material. Furthermore, when processing different types of metallurgical products, the workers use a wrench to rotate the rotating shaft 13, causing the rotating shaft 13 to drive the threaded block to rotate, thereby separating the threaded block from the threaded hole 14 opened in the connecting rod 11. At this time, the electric telescopic rod 9 is activated to drive the connecting rod 10 to move upward, thereby separating the connecting rod 10 and the connecting rod 11. Then, the connecting rod 11 and the lower mold 4 are replaced. Then, the workers disassemble the keyed hydraulic cylinder 5 and the fixing rod 6, and then disassemble the fixing rod 6, the pressure plate 7 and the upper mold 8, and then replace them with new fixing rod 6, pressure plate 7 and upper mold 8. The mold 8 connects the new fixing rod 6 to the hydraulic cylinder 5. The raw material is then placed into the lower mold 4. The hydraulic cylinder 5 is then activated, causing the pressure plate 7 at the bottom of the fixing rod 6 to move downwards, thus closing the lower mold 4 and the pressure plate 7. This presses the metallurgical raw material within the lower mold 4, completing the pressing of the metallurgical product. The discharge mechanism allows the lower mold 4 to be moved upwards after pressing the metallurgical raw material, facilitating the unloading and removal of the metallurgical product by the operator, further enhancing the equipment's practicality.

[0019] The electric telescopic rod 9 is fixedly connected to a fixing ring 15 near the top of its outer contour. The top of the fixing ring 15 is detachably connected to the top of the inner wall of the housing 1. The bottom of the fixing ring 15 is provided with fixing bolts 16 arranged in a circular array with the axis of the fixing ring 15 as the center. The inner wall of the top of the housing 1 is provided with screw holes that are compatible with the fixing bolts 16.

[0020] After the electric telescopic rod 9 is damaged, the staff will remove the fixing bolts 16 on the fixing ring 15, and then remove the fixing ring 15 on the electric telescopic rod 9 from the top of the inner wall of the box 1. Then the electric telescopic rod 9 can be replaced or repaired, thereby increasing the staff's maintenance efficiency of the electric telescopic rod 9.

[0021] Working principle: First, the raw material is placed into the lower mold 4. Then, the hydraulic cylinder 5 is activated to move the pressure plate 7 at the bottom of the fixed rod 6 downward, thereby closing the lower mold 4 and the pressure plate 7 to press the metallurgical raw material in the lower mold 4, thus completing the pressing of the metallurgical product. By activating the electric telescopic rod 9, the connecting rod 10 is moved upward, which in turn moves the connecting rod 11 upward. Then, the connecting rod 11 moves the lower mold 4 upward, thereby separating the lower mold 4 from the processed metallurgical product inside the lower mold 4. The staff can then separate and discharge the material.

[0022] Furthermore, when processing different types of metallurgical products, the operator uses a wrench to rotate the rotating shaft 13, causing the rotating shaft 13 to drive the threaded block to rotate, thereby separating the threaded block from the threaded hole 14 opened in the connecting rod 11. At this time, the electric telescopic rod 9 is activated to drive the connecting rod 10 to move upward, thereby separating the connecting rod 10 and the connecting rod 11. Then, the connecting rod 11 and the lower mold 4 are replaced. Then, the operator disassembles the keyed hydraulic cylinder 5 and the fixing rod 6, and then disassembles the fixing rod 6, the pressure plate 7 and the upper mold 8. Then, a new fixing rod 6, the pressure plate 7 and the upper mold 8 are replaced, and the new fixing rod 6 is keyed to the hydraulic cylinder 5. Then, the equipment can be started to process different types of metallurgical products.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
