Abstract
Description
Technical Field
[0001] This utility model relates to the field of white core casting and forging processing technology, specifically to an annealing kiln for easy cleaning of white core casting and forging. Background Technology
[0002] White-core malleable castings are a special type of cast iron with a silvery-white cross-section and a thick decarburized layer on the outer edge, resulting in an uneven microstructure. The main characteristic of white-core malleable castings is their unevenness. In thin-walled castings with a thickness of less than 6 mm, the outer layer is composed entirely of ferrite, which gives it good weldability, while the core contains pearlite but no annealed graphite. For castings with a wall thickness in the range of 6 to 15 mm, the outer layer is also ferrite, but the core not only contains pearlite but also nodular graphite and may even contain residual free cementite. White-core castings and forgings require annealing in a furnace during processing.
[0003] Existing annealing furnaces accumulate a lot of dust and impurities inside during long-term use. If they are not cleaned in time, it will affect the processing effect of the annealing furnace. At the same time, the annealing furnace is large in size and requires multiple people to operate when it is opened, which is a waste of manpower and resources and reduces efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide an annealing furnace for white-core castings and forgings that is easy to clean, in order to solve the problems mentioned in the background art, such as the accumulation of a large amount of dust and impurities inside the existing annealing furnace during long-term use, which will affect the processing effect of the annealing furnace if not cleaned in time. At the same time, the annealing furnace is large in size and requires multiple people to operate when opening, which is a waste of manpower and resources and reduces efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an annealing kiln for easy cleaning of white-core castings and forgings, comprising a kiln body, with pads provided on both sides of the kiln body near the top, and an adjusting screw rotatably mounted on the top of each pad via a rotating shaft; a kiln cover movably mounted on the top of the kiln body, with adjusting blocks provided on both sides of the kiln cover; a cylinder mounted on the top of the kiln cover, with a telescopic rod extending through the kiln cover at the telescopic end of the cylinder; a crossbar mounted at the bottom of the telescopic rod; and a cleaning turntable mounted on the outer end of each crossbar.
[0006] Preferably, a cleaning pad is provided around the outer surface of the cleaning turntable, and the cleaning pad is made of rubber.
[0007] Preferably, a sealing plate is movably installed on one side surface of the kiln body via a hinge. The sealing plate is provided with a locking seat on the side surface near the top and bottom, and a locking buckle is provided on the kiln body surface corresponding to the locking seat.
[0008] Preferably, a protective baffle is inserted through one side of the kiln cover near the bottom, and a handle is provided on one side surface of the sealing plate.
[0009] Preferably, the adjusting block and the adjusting screw are threadedly connected, the top end of the adjusting screw is provided with an adjusting knob, and the top end of the adjusting knob is provided with a handle.
[0010] Preferably, the bottom of the kiln body is integrally formed with a conical discharge port, the bottom end of the conical discharge port is provided with a bottom cover, and the bottom of the kiln body is surrounded by support legs, and the bottom end of each support leg is provided with a positioning suction cup.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This annealing kiln, made of white-core cast forgings and forgings, is easy to clean. During daily use, a cylinder drives a telescopic rod to reciprocate in real time. The telescopic rod drives a cleaning turntable and a cleaning pad to move up and down along the inner wall of the kiln. The cleaning pad rubs against the inside of the kiln, effectively removing dust and impurities adhering to the inside of the kiln in real time. This replaces traditional cleaning methods and effectively improves the overall cleaning efficiency.
[0013] This type of white-core cast forging annealing kiln is easy to clean. During daily use, when it is necessary to open the kiln body, the kiln can be opened or closed by manually holding the handle and turning the adjustment knob. The adjustment knob drives the adjustment screw to rotate, and the screw thread drives the kiln cover to rise or fall, thus effectively saving manpower and material resources.
