Description

Technical Field

[0001] This utility model relates to the field of sintering furnace technology, specifically to a temperature uniformity control device for a diamond-tipped high-temperature vacuum sintering furnace. Background Technology

[0002] A vacuum sintering furnace is a furnace that performs protective sintering on heated items in a vacuum environment. There are many heating methods, such as resistance heating, induction heating, and microwave heating. Vacuum sintering furnaces use induction heating to perform protective sintering on heated items. As a core component of superhard tools, the performance of diamond cutting tools after sintering directly determines the lifespan and efficiency of cutting and grinding tools.

[0003] The existing technology has the following problems: In general, the trays used inside the sintering furnace are mostly fixed. As a result, when the sintering material is piled on the tray, the temperature of the item to be sintered in the center rises more slowly, which is not conducive to the sintering process and thus affects the quality of the sintered item.

[0004] Therefore, this utility model provides a temperature uniformity control device for a high-temperature vacuum sintering furnace for diamond cutting heads to solve the above-mentioned problems. Utility Model Content

[0005] This invention provides a temperature uniformity control device for a high-temperature vacuum sintering furnace for diamond cutting tools, aiming to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a sintering furnace body and a rotating mechanism assembled outside the sintering furnace body, wherein a placement cylinder is rotatably connected to the inner wall of the sintering furnace body, and a plurality of limiting holes are provided at one end of the placement cylinder, and a stabilizing mechanism is assembled on the surface of the placement cylinder.

[0007] The rotating mechanism includes a cover plate hinged to one side of the sintering furnace body and a fixing block fixedly connected to the surface of the cover plate. The surface of the fixing block has a sliding groove, and an installation block is slidably connected inside the sliding groove. A servo motor is fixedly installed on the top of the installation block, and a connecting column is fixedly connected to the output end of the servo motor. One end of the connecting column passes through the cover plate and is fixedly connected to a disc with the same diameter as the placement cylinder. Several limiting posts are fixedly connected to the surface of the disc, and the size of the limiting posts is adapted to the limiting holes. A spring is fixedly connected to one side of the inner wall of the sliding groove, and a buffer rod is sleeved inside the spring. One end of the spring is fixedly connected to one side of the installation block.

[0008] As a preferred technical solution of this application, the stabilizing mechanism includes a fixing rod fixedly connected to the inner wall of the sintering furnace body and a limiting ring fixedly connected to one end of the fixing rod, wherein the inner wall of the limiting ring is slidably connected to the surface of the placement cylinder.

[0009] As a preferred technical solution of this application, the surface of the limiting ring is provided with a rectangular hole, and a movable column is rotatably disposed inside the rectangular hole.

[0010] As a preferred technical solution of this application, a handle is fixedly connected to one side of the surface of the cover plate, and the surface of the handle is provided with rounded corners.

[0011] As a preferred technical solution of this application, a hydraulic rod is fixedly installed on the other side of the inner wall of the chute, and the output end of the hydraulic rod is located on the other side of the mounting block.

[0012] As a preferred technical solution of this application, a support leg is fixedly connected to one side of the surface of the sintering furnace body, and the surface of the support leg is provided with rounded corners.

[0013] As a preferred technical solution of this application, the disc and the placement cylinder are on the same axis, and one side of the disc can completely fit into one side of the placement cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By setting up a rotating mechanism and a placement cylinder, and covering the cover plate, the limiting post on the surface of the disc is ensured to be in close contact with one end of the placement cylinder. The servo motor is then started, causing it to drive the connecting post and the disc to rotate. At the same time, the spring applies pressure to the mounting block, pushing it to move within the slide groove. This causes the servo motor, connecting post, and disc to move closer to the surface of the placement cylinder, allowing the limiting post to slide smoothly into the limiting hole. This action causes the placement cylinder to rotate, causing the items inside the cylinder to move, the accumulated items to turn over, and to be heated evenly. This allows multiple items to rise in temperature simultaneously, which helps to improve the quality of the sintered material. At the same time, the limiting ring and the movable post facilitate better rotation of the placement cylinder and improve the stability of the placement cylinder during rotation.
