Technical Field

[0001] The utility model relates to the technical field of annealing furnaces, in particular to an annealing furnace structure for producing lead-calcium alloys. Background Art

[0002] Lead-calcium alloy is a calcium-containing lead alloy used to manufacture maintenance-free lead-acid battery grids, especially negative grids, with a calcium content of only about 0.1%.

The above document still has shortcomings. When in use, the handle is turned through the arrangement of the handle, the active conical wheel, the driven conical wheel and the screw rod, and the screw rod is driven to rotate through the active conical wheel and the driven conical wheel, so as to achieve the effect of driving the screw rod sleeve to move left or right, and then achieve the effect of moving the conveyor to the left or right. The setting of the carrier and the conveyor, after the conveyor moves to the interior of the furnace body, the conveyor works normally to transfer the casting to the carrier, and then the conveyor is moved out of the furnace body, so as to achieve the effect of sealing the interior of the furnace body, and then achieve the effect of convenient feeding of the annealing furnace. However, when the annealing furnace in the above document is used to process lead-calcium alloy parts, it is only suitable for loading, and it is not convenient to take out the processed lead-calcium alloy parts. At the same time, when more lead-calcium alloy parts need to be annealed at the same time, the traditional method is to stack the lead-calcium alloy parts together and put them into the interior of the annealing furnace for annealing. When more lead-calcium alloy parts are annealed at the same time, it is easy to cause uneven heating of the lead-calcium alloy parts, thereby affecting the annealing effect. Utility Model Content

The support plate 301 is fixedly connected to the lower surface of the base 1. The outer wall of the support plate 301 is fixedly connected to the hydraulic cylinder 302. The hydraulic cylinder of the hydraulic cylinder 302 is fixedly connected to the vertical plate 303. The hydraulic cylinder 302 drives the vertical plate 303 to move. The outer wall of the vertical plate 303 is fixedly connected to the baffle 304. The vertical plate 303 drives the baffle 304 to move.
