Description

Technical Field

[0001] This utility model relates to the field of furnace cover closing technology, specifically to a furnace cover closing buffer structure for an atmosphere well furnace. Background Technology

[0002] An atmosphere pit furnace is a heating device used for high-temperature processing. It typically consists of a vertical cylindrical furnace chamber and an upper heater. Different atmospheric environments, such as oxidizing, reducing, or inert atmospheres, can be created inside the furnace by controlling the type and flow rate of the incoming gas. Atmosphere pit furnaces are widely used in metal heat treatment, ceramic manufacturing, and other processes requiring heating and processing under specific atmospheric conditions.

[0003] The furnace cover of a traditional atmosphere pit furnace is closed directly by hydraulic or mechanical drive. The moment of closure is prone to violent collision, which will wear down the furnace mouth sealing ring, thus affecting the atmosphere sealing performance, and will also cause deformation of the furnace cover and furnace body structure.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-3 As shown, this utility model is a closed buffer structure for an atmosphere well furnace cover, comprising: The buffer mechanism 100 includes a circular hole 110, a fitting plate 120, an elastic element 130, a first inclined column 140, a second spring 150, an insertion hole 160, and a square groove 170. A circular hole 110 is formed at the edge of the furnace opening. The bottom of the fitting plate 120 is fixedly connected to the bottom of the elastic element 130, and the bottom of the elastic element 130 is fixedly connected to the bottom of the circular hole 110. A square groove 170 is formed inside the side wall of the furnace opening edge. A first inclined column 140 is slidably connected inside the square groove 170. The two ends of the second spring 150 are respectively fixedly connected to the side wall of the first inclined column 140 and the side wall of the square groove 170. An insertion hole 160 is formed on the side wall of the fitting plate 120. When the furnace lid is closed, the furnace lid drives the fitting plate 120 to slide down and... The elastic member 130 is compressed, causing the fitting plate 120 to be pressed into the round hole 110 and contact the inclined surface of the first inclined column 140. The first inclined column 140 is pressed into the square groove 170 by the inclined surface, and the second spring 150 is compressed. When the insertion hole 160 on the fitting plate 120 is aligned with the first inclined column 140, the second spring 150 rebounds and drives the first inclined column 140 to be inserted into the insertion hole 160, so that the fitting plate 120 is fixed. At this time, the furnace cover is completely closed, so that the furnace cover will not directly contact the furnace opening when it is closed. Connecting rods 181 are fixedly connected to both sides of the bottom of the composite plate 120. A sliding plate 182 is fixedly connected to the bottom of the connecting rod 181. A groove 183 is opened on the side wall of the round hole 110. The sliding plate 182 is slidably connected in the groove 183. When the composite plate 120 slides down, it drives the connecting rod 181 to slide down. The connecting rod 181 drives the sliding plate 182 to slide down in the groove 183, which increases the lateral support of the elastic element 130 and prevents the elastic element 130 from being bent by the collision of the furnace cover. The elastic element 130 includes a telescopic column 131 and a first spring 132; The telescopic column 131 is fixedly connected to the bottom of the interlocking plate 120 and the bottom of the round hole 110 at both ends, and the first spring 132 is fixedly connected to the bottom of the interlocking plate 120 and the bottom of the round hole 110 at both ends. The telescopic column 131 passes through the first spring 132. The interlocking plate 120 slides down, causing the telescopic column 131 and the first spring 132 to retract, absorbing the impact force of the furnace cover closing. A circular groove 111 is provided on the top side wall of the circular hole 110. The fitting plate 120 is fitted into the circular groove 111. After the furnace cover is completely closed, the fitting plate 120 is embedded in the circular groove 111, so that there will be no large gap between the furnace cover and the furnace opening after the furnace cover is closed. Working principle: When the furnace lid is closed, the furnace lid causes the fitting plate 120 to slide down and press the telescopic column 131 and the first spring 132 to contract, absorbing the impact force of the furnace lid closing. At the same time, the sliding plate 120 causes the connecting rod 181 to slide down, and the connecting rod 181 causes the sliding plate 182 to slide down the slide groove 183, increasing the lateral support of the elastic element 130. The fitting plate 120 presses into the round hole 110 and contacts the inclined surface of the first inclined column 140, and presses the first inclined column 140 into the square groove 170 through the inclined surface. The inner sliding mechanism compresses the second spring 150. When the insertion hole 160 on the fitting plate 120 aligns with the first inclined column 140, the second spring 150 rebounds and drives the first inclined column 140 to insert into the insertion hole 160, thus fixing the fitting plate 120. At this time, the furnace cover is completely closed, and the fitting plate 120 is embedded in the circular groove 111, so that the furnace cover will not directly contact the furnace opening when it is closed, preventing wear of the sealing ring. The elastic element 130 provides cushioning to prevent the furnace opening from deforming due to collision when the furnace cover is closed.

[0018] Please see Figure 1-3 As shown, this embodiment, based on the above embodiment, further includes: The reset mechanism 200 includes an L-shaped column 210, a cylindrical column 220, a second inclined column 230, and a third spring 240. The end of the L-shaped column 210 is fixedly connected to the side wall of the first inclined column 140. The two ends of the side wall of the cylindrical column 220 are slidably connected to the first side plate 271, which is fixedly connected to the side wall of the furnace opening. The second inclined column 230 is fixedly connected to the end of the cylindrical column 220. The two ends of the third spring 240 are respectively fixedly connected to the side wall of the cylindrical column 220 and the side wall of the first side plate 271. When the furnace cover is opened and the elastic element 130 and the fitting plate 120 need to be reset, the cylindrical column 220 is pushed to drive the second inclined column 230 to slide, so that the inclined surface of the second inclined column 230 contacts the short side of the L-shaped column 210 and slides the L-shaped column 210 outward along the inclined surface. The L-shaped column 210 drives the first inclined column 140 to be pulled out from the insertion hole 160. At this time, the elastic element 130 rebounds and drives the fitting plate 120 to slide up and out of the circular hole 110 to complete the reset. The reset mechanism 200 also includes an eccentric wheel 250 and a motor 260; The motor 260 is fixedly connected to the second side plate 272, which is fixedly connected to the side wall of the furnace opening. The eccentric wheel 250 is fixedly connected to the power output end of the motor 260. The curved surface of the eccentric wheel 250 fits against the end of the cylinder 220. When the motor 260 is started, it drives the eccentric wheel 250 to rotate, causing the cylinder 220 to slide to the right along the curved surface of the eccentric wheel 250. The eccentric wheel 250 rotates one revolution, completing one reset. The short side of the L-shaped column 210 has a bevel 211, which fits into the bevel of the second inclined column 230. A baffle 221 is fixedly connected to the side wall of the cylindrical column 220. The side wall of the baffle 221 is fixedly connected to one end of the third spring 240. The bevel 211 makes it easier for the second inclined column 230 to drive the L-shaped column 210 to slide outward. The sliding of the cylindrical column 220 causes the baffle 221 to slide and squeeze the third spring 240. Working principle: When the furnace cover is opened and the elastic element 130 and the fitting plate 120 need to be reset, the motor 260 is started to drive the eccentric wheel 250 to rotate, causing the cylinder 220 to slide to the right along the curved surface of the eccentric wheel 250. The cylinder 220 drives the second inclined column 230 to slide, so that the inclined surface of the second inclined column 230 contacts the inclined opening 211 of the short side of the L-shaped column 210 and slides the L-shaped column 210 outward along the inclined surface. The L-shaped column 210 drives the first inclined column 140 to be pulled out from the insertion hole 160. At this time, the elastic element 130 rebounds and drives the fitting plate 120 to slide up and out of the round hole 110 to complete the reset. The eccentric wheel 250 rotates one revolution to complete one reset. After the eccentric wheel 250 rotates one revolution, the third spring 240 rebounds and drives the cylinder 220 to slide to the left, so that the end of the cylinder 220 is in contact with the eccentric wheel 250 again, realizing the automatic reset of the elastic element 130 and the fitting plate 120, improving efficiency.
