Description

Technical Field

[0001] This utility model relates to a bell-shaped furnace plate material rack device, and more particularly to an annealing auxiliary material rack device for processing non-ferrous metal plates in a bell-shaped furnace. Background Technology

[0002] Currently, non-ferrous metals are annealed using bell furnaces. The typical structure of a bell furnace corresponds to the annealing of coils. When directly annealing sheet metal using a bell furnace, due to the different shapes of the sheet metal and coil, the common practice is to stack the sheet metal flat on the convection plate of the coil and then suspend it on the bell furnace's circulating fan. Because the sheet metal is placed flat on the coil plate, it blocks the convection holes, hindering the airflow of the circulating fan and convection holes, resulting in an imbalance between the furnace temperature and the overall temperature of the sheet metal. This affects the annealing process and the quality of the material in the bell furnace. In view of these reasons, an auxiliary material rack device for annealing non-ferrous metal sheet metal in a bell furnace is proposed. Utility Model Content

[0003] The purpose of this invention is to overcome the problem that when annealing sheet metal directly in a bell-type furnace, the sheet metal is stacked flat on the convection plate of the coil, blocking the convection holes and causing an uneven temperature between the furnace and the sheet metal, thus affecting the annealing process. Through a reasonable design, this invention provides an auxiliary material rack device for annealing non-ferrous metal sheet metal in a bell-type furnace. This auxiliary material rack device uses a support plate with evenly distributed convection holes and a central air duct to form an airflow circulation channel. A circulating fan delivers air to create a circulating airflow within the bell-type furnace. Three feeding units are set on the support plate, arranged around the air duct. Non-ferrous metal sheet metal is vertically placed on each of the three feeding units for annealing, ensuring smooth airflow within the bell-type furnace, uniform overall temperature of the non-ferrous metal sheet metal, and improved quality.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: an annealing auxiliary material rack device for processing non-ferrous metal plates in a bell-shaped furnace, comprising: an air duct, a column, a positioning hinge, a column connecting liner, a base frame, a lifting lug, a material support plate, convection holes, and a circulating fan; a circulating fan is installed at the center of the bell-shaped furnace opening, and a material support plate is installed above the bell-shaped furnace opening. The material support plate is annular, with an air duct hole pre-reserved at the center of the material support plate, an air duct in the middle of the air duct hole, and a circulating fan at the lower end of the air duct; convection holes are evenly distributed around the air duct on the material support plate, and a circulating fan at the lower end of the air duct; the circulating fan is used for air supply to the air duct, and the air duct and convection holes are configured as airflow circulation channels in the bell-shaped furnace.

[0005] The base frame is radially and evenly distributed around the air duct hole under the material support plate; each base frame is made of I-beam steel, and there are six sets of base frames around the circumference. There are arc-shaped connecting plates between the six sets of base frames, and the six sets of base frames are arranged into a ring frame; three balanced lifting lugs are evenly distributed on the outer side of the ring frame, and the three lifting lugs are respectively located at the outer end of the base frame. The ring frame is used to support the material support plate and the bell furnace opening.

[0006] The base frame extends out at both ends to form frame heads. Each of the six frame heads facing the same direction is equipped with a connecting column liner. A column is installed at the outer end of each connecting column liner. The bottom of each of the six connecting column liners is fixed to the frame head. A material support plate is fixed on the top of each of the six connecting column liners. The six connecting column liners are used as padding for the material support plate. The outer ends of the six connecting column liners are used to fix the columns.

[0007] Positioning hinges are provided on the same side of the lower part of each column, and the six columns are set as three pairs of columns. Two adjacent columns are set as a pair of columns. A feeding unit is set on the corresponding material support plate inside each pair of columns. Three feeding units are set on the material support plate and the three feeding units are arranged around the air duct. A locking steel strip is set between a pair of positioning hinges of a pair of columns, and a set of plates is set between the locking steel strip and a pair of columns.

[0008] Each of the three feeding units is equipped with two different sizes of sheet metal assemblies, which are either 30 sheets or 20 sheets. The 30-sheet sheet assembly has the following dimensions: 10mm thick × 1000mm wide × 1600mm long. The 20-sheet sheet assembly has the following dimensions: 15mm thick × 600mm wide × 2000mm long. A pair of uprights are used to support and position the annealed sheet metal in one feeding unit, and the positioning hinges are used to lock and fix the annealed sheet metal.

[0009] Working principle: Relying on the air guide port in the center of the device that matches the size of the circulating fan, the fan circulation convection system runs smoothly, and the hot air can circulate evenly and continuously in the bell furnace, which helps to improve the uniformity of furnace temperature; the plates are bundled and placed upright on the device to increase the heating area and heat conduction efficiency of the plates, thereby improving the temperature uniformity of the plate materials.

[0010] Beneficial effects: The annealing auxiliary material rack device of this utility model forms an airflow circulation channel through the evenly distributed convection holes on the material support plate and the central air duct. The circulating airflow in the bell furnace is formed by the air supply of the circulating fan. The material support plate is equipped with three feeding units, which are reasonably arranged around the air duct. Non-ferrous metal plates are placed vertically on the three feeding units for annealing, which ensures smooth airflow in the bell furnace, uniform temperature of the non-ferrous metal plates, and improves the quality of the non-ferrous metal plates.
