Description

Technical Field

[0001] The utility model relates to the technical field of sintering furnaces, in particular to a powder metallurgy sintering furnace. Background Art

[0002] Powder metallurgy is a process for manufacturing metal parts and materials. It involves mixing metal powder with a possible binder, then forming the part through pressing or cold isostatic pressing. Finally, a sintering process binds the powder particles together to form a solid material with the desired properties and shape. Powder metallurgy sintering furnaces use high-temperature heating and possibly pressure to sinter the powdered material into a solid block. There are many types of sintering furnaces, categorized by heat source and structure, such as natural gas, coal gas, oil, or electricity. Electric furnaces are commonly used due to their cost-effectiveness, convenience, and ease of control. Existing powder metallurgy sintering furnaces, after sintering for a period of time, can produce carbon deposits and nodules inside the furnace, causing unevenness. Furthermore, during operation, these deposits can rub against the conveyor belt, causing debris to become stuck in the belt. Existing powder metallurgy sintering furnaces are difficult to clean the conveyor belt promptly, which can lead to debris and other foreign matter clinging to the blanks, affecting product quality.

Both ends of the top of the support shell 110 are transmission-connected to two mesh belt drive rods 140, and the outer sides of the four mesh belt drive rods 140 are transmission-connected to the mesh belt body 120. A motor 130 is fixedly connected to the top of one side of the support shell 110, and the output end of the motor 130 passes through the side wall of the support shell 110 and is fixedly connected to one end of the mesh belt drive rod 140 at the corresponding position. A knocking mechanism 200 is provided at both ends of the support shell 110, and two sliding through holes 2 112 are provided on the other side of the support shell 110. A brushing mechanism 300 is matched with the support shell 110.

[0024] Specifically, by starting the motor 130, the motor 130 is used to drive the mesh belt driving rod 140 at the corresponding position to rotate, so that the mesh belt body 120 is rotated, and then the rotating mesh belt body 120 is used to facilitate the transportation of the green body to the interior of the sintering furnace body 100, and the sintering furnace body 100 is used to facilitate the sintering treatment of the green body, and the two knocking mechanisms 200 and the brushing mechanism 300 are used to facilitate the cleaning of foreign matter adhered to the mesh belt body 120, thereby avoiding the foreign matter adhered to the mesh belt body 120 from adhering to the green body and affecting the quality of the green body.

[0025] like Figure 2-5 As shown, in this embodiment, both ends of the interior of the support shell 110 are fixedly connected with guide plates 170, and the bottoms of both sides of the support shell 110 are provided with sliding through holes 111, and the support shell 110 is equipped with a collection shell 180, and the two ends of the collection shell 180 are respectively slidably connected with the sliding through holes 111 at corresponding positions, and the top of the collection shell 180 contacts the bottoms of the two guide plates 170, and the bottom of the support shell 110 is evenly fixed with a plurality of fixing frames 150, and the bottom of the fixing frame 150 is fixedly connected with the fan 160, and the knocking mechanism 200 includes a fixed shell 210, and the two ends of the fixed shell 210 are evenly fixed with the inner wall of the support shell 110, and the bottoms of the two inner walls of the fixed shell 210 are A connecting plate 230 is rotatably connected, a rotating seat 220 is provided on the outside of the fixed shell 210, and a knocking rod 221 is rotatably connected inside the rotating seat 220, one end of the connecting plate 230 is fixedly connected to the rotating seat 220, and a fixed plate 240 is fixedly connected between the other ends of the two connecting plates 230, a rectangular shell 270 is fixedly connected to the middle position inside the fixed shell 210, and an elliptical block 260 is rotatably connected inside the rectangular shell 270, one side of the rectangular shell 270 is fixedly connected to motor 250, and the output end of motor 250 passes through the side wall of the rectangular shell 270 and is fixedly connected to the middle position of one end of the elliptical block 260, and the outer wall of the elliptical block 260 is fixedly connected to a push plate 280.
