[0002] Powder metallurgy is a process technology for manufacturing metal materials, composite materials and various types of products. Its basic principle is to first mix metal or non-metal powders evenly, and then use pressing, sintering and other process steps to make them into products with certain shapes, sizes and performances. The use of powder metallurgy to produce gears can achieve the manufacture of complex shapes. For gears, which have specific tooth shapes and structural requirements, they can accurately meet the design requirements. Secondly, powder metallurgy can produce high-precision gears to ensure the accuracy and stability of transmission. Furthermore, this process can achieve large-scale production, thereby reducing costs.

The above-mentioned scheme solves the problem that when the above-mentioned existing gear sintering device sinters the formed gear, it is necessary to wait for the gear to cool down before taking it out and loading it after sintering. In this way, the entire sintering chamber needs to be reheated multiple times during continuous sintering. Therefore, the cooling waiting time plus the time for reheating to the specified temperature will greatly extend the normal processing cycle of the entire sintering process, resulting in low sintering efficiency in actual operation.

[0030] In this embodiment, the sintering heater 102 is installed on the workbench 101. The workbench 101 is composed of a bottom bracket and an upper processing box. The sintering heater 102 is arranged in a heating box above the workbench 101 to heat the gears placed in the designated area.

[0031] The rotating column 103 is rotatably connected to the working frame 101 and is located on one side of the working frame 101. The connecting frame 104 is fixedly connected to the rotating column 103 and is located on one side of the rotating column 103. The temperature insulation plate 105 is connected to the working frame 101 through the regulating component and is located on one side of the working frame 101. The heat conduction plate 106 is connected to the working frame 101 through the regulating component and is located on one side of the working frame 101. The regulating component is connected to the working frame 101. The opening and closing member is connected to the working frame 101, the placing member is connected to the connecting frame 104, the conducting member is connected to the working frame 101, the fixing bracket 107 is fixedly connected to the working frame 101 and is located on one side of the working frame 101; the driving plate 108 is fixedly connected to the insulation plate 105 and the heat conducting plate 106, and is slidably mounted on one side of the fixing bracket 107; the driving component is connected to the driving plate 108;The rotating component is connected to the rotating column 103, and the rotating column 103 is rotatably arranged on the working frame 101. Three connecting frames 104 are evenly arranged on the rotating column 103, and each connecting frame 104 is provided with a corresponding mechanism for placing the forming gear. Two insulation plates 105 and a heat conducting plate 106 are installed at the bottom of the driving plate 108. The insulation plates 105 and the heat conducting plates 106 match the insertion grooves provided on the top box of the working frame 101. The two insulation plates 105 and the heat conducting plates 106 can be used to The interior of the box above the workbench 101 is divided into three areas. The taking area is composed of two insulation plates 105, and the other two areas are respectively a preheating area and a heating area. The sintering heater 102 is arranged on the top of the heating area. When working normally, the two insulation plates 105 and the heat conducting plate 106 will separate the three areas. Since the taking area is blocked by the two insulation plates 105, the temperature in the taking area will not be affected by the sintering heater 102 during processing. Since the preheating area and the heating area are separated by the heat conducting plate 106, The temperature in the preheating zone will slowly rise as the temperature inside the heating zone rises. As for the heating zone, it is directly heated by the sintering heater 102. In this way, by preheating the molded gear in advance, the normal sintering cycle of the gear can be shortened. Moreover, during the preheating, the gear inside the heating zone is also sintered normally, so that preheating and sintering can be carried out at the same time. When sintering is completed, the driving plate 108 is driven to move on the fixed bracket 107, and then the two insulation plates 105 and the heat conducting plate 106 are lifted, so that the sintered gear can be rotated by the rotating column 103. The finished workpiece is transferred to the pick-up area provided on the workbench 101, and the preheated workpiece can enter the heating area. The workpiece in the pick-up area enters the preheating area. When the process position conversion of the rotating column 103 is completed, the driving plate 108 drives the two insulation plates 105 and the heat conducting plate 106 to move down again to separate the corresponding areas. During the process conversion, the entire top box of the workbench 101 is relatively sealed, so the temperature inside the heating area will not drop rapidly, making the subsequent preheated workpieces more efficient. ;

[0032] Secondly, the guide bracket 109 is fixedly connected to the work frame 101 and is located on one side of the work frame 101; the sliding door leaf 110 is slidably connected to the guide bracket 109 and is located on one side of the guide bracket 109; the sliding component is connected to the sliding door leaf 110, the sliding screw 116 is threadedly connected to the sliding door leaf 110 and is rotatably mounted on one side of the guide bracket 109; the output shaft of the sliding motor 117 is connected to the sliding screw 116, the sliding motor 117 is fixedly mounted on one side of the guide bracket 109, and the guide bracket 109 is fixedly mounted on the work frame 1 01 top, the sliding door leaf 110 slidingly provided on the guide bracket 109 is adapted to the placing and taking through groove provided in the taking area of ​​the work frame 101, and the boss of the sliding door leaf 110 is provided with a threaded hole matching the sliding screw 116, and the sliding screw 116 is fixed to the output shaft of the sliding motor 117. When the sliding motor 117 drives the protective screw to rotate, the sliding screw 116 can drive the sliding door leaf 110 to slide accordingly on the guide bracket 109, thereby realizing the opening and closing of the taking area in the work frame 101, so as to facilitate the user to perform corresponding loading and unloading operations.

[0033] At the same time, the driving screw 111 is threadedly connected to the driving plate 108 and is rotatably mounted on one side of the fixed bracket 107; the output shaft of the driving motor 112 is connected to the driving screw 111, and the driving motor 112 is fixedly mounted on one side of the fixed bracket 107; the gear ring 113 is fixedly connected to the rotating column 103 and is located on one side of the rotating column 103; the rotating gear 114 is meshed with the gear ring 113 and is rotatably mounted on one side of the working frame 101; the output shaft of the rotating motor 115 is connected to the rotating gear 114, and the rotating motor 115 is fixedly mounted on one side of the working frame 101, and the driving screw 111 is provided on the driving plate 108 The output shaft of the driving motor 112 is fixed to the driving screw 111 so that the user can drive the driving plate 108 by cooperating with the driving screw 111 through the driving motor 112. The gear ring 113 is fixedly arranged at the bottom of the rotating column 103. The gear ring 113 is rotatably mounted on the bottom of the working frame 101 to engage with the rotating gear 114. The rotating gear 114 is fixed to the output shaft of the rotating motor 115. When the rotating motor 115 drives the rotating gear 114 to rotate, the rotating gear 114 can drive the gear ring 113 and the rotating column 103 to rotate, thereby completing the corresponding drive of the rotating column 103.

[0034] When a powder metallurgy gear sintering device and its system of this embodiment are used, the forming gear is placed by the connecting frame 104 in cooperation with the placing component, and then the sliding motor 117 cooperates with the sliding screw 116 to drive the sliding door leaf 110 to close the box opening on the top of the working frame 101, and then the driving motor 112 cooperates with the driving screw 111 to drive the driving plate 108, so that the driving plate 108 drives the two insulation plates 105 and the heat conduction plate 106 to move downward, thereby separating the three areas of the box above the working frame 101 accordingly, and then by The sintering heater 102 normally sintered the molded gears in the heating zone. Under the action of the heat conducting plate 106, the molded gears in the preheating zone can be preheated by the waste heat emitted from the heating zone. When the molded gears in the heating zone are processed, the driving motor 112 cooperates with the driving screw 111 to drive the driving plate 108 to move upward. Then, the rotating motor 115 can drive the rotating gear 114 to cooperate with the gear ring 113 to drive the rotating column 103 to move, so as to convert the molded gears originally placed in the three zones, so that the molded gears originally in the picking zone can enter the preheating zone. The molded gears that have completed preheating in the preheating zone can enter the heating zone, and the molded gears that have completed sintering in the heating zone can enter the picking zone. During the entire conversion process of the rotating column 103, the box above the workbench 101 is still in a closed state, so the heat will only flow in a small amount in the three areas and will not dissipate too quickly. After the rotating column 103 rotates to the specified position, the driving plate 108 can drive the insulation plate 105 and the heat conduction plate 106 to move down again through the driving motor 112 and the driving screw 111 to facilitate the next round of processing, and the molded gears in the picking zone will be removed after a certain period of time. After cooling, the user can use the sliding motor 117 and the sliding screw 116 to drive the sliding door leaf 110 to move upward, so that the operator can remove the processed workpiece and then install and place the new workpiece. During the placement, the forming gears in the heating zone and the preheating zone of the workbench 101 can still continue to be processed, so that the processing and loading and unloading of the workpiece can be carried out simultaneously through the provided components, and the preheating by utilizing the heat generated by heating can not only reduce energy consumption but also shorten the time required for subsequent heating to a certain extent, so that the overall processing efficiency is higher in actual operation.
