Description

Technical Field

[0001] This application relates to the technical field of metal material processing. Specifically, it relates to a power-taking device for an electric heating bell-type furnace. Background Art

[0002] Material annealing has two functions. One is to improve or eliminate various tissue defects and residual stresses caused during processes such as casting, forging, rolling, and welding. The other is to refine the grains and improve the structure to enhance the mechanical properties of the workpiece. In the field of metal material annealing, the bell-type furnace occupies an important position in the field of cold-rolled steel annealing furnaces due to its flexible production organization and strong operability. According to the power source, it can usually be divided into a gas-fired bell-type furnace and an electric heating bell-type furnace. When annealing with a gas-fired bell-type furnace, first stack the steel, then put on the inner cover and heating cover, and introduce gas and air to burn and heat between the heating cover and the inner cover. Through the heat transfer between the protective atmosphere of the inner cover and the steel, the steel is heated to the process temperature to complete the annealing requirements. Subsequently, remove the heating cover and replace it with a cooling cover to start the cooling stage. After cooling is completed, it represents the end of the annealing process. During the stage of putting on the heating cover and introducing gas, usually the method of connecting a metal hose to a hard pipe is adopted, and the operation is relatively cumbersome. When the number of bell-type furnace units is large, this method will increase the labor and operating costs, and when the seal between the hose and the hard pipe is not good, the safety factor is not high. The traditional electric heating bell-type furnace is relatively convenient for power taking and also saves more gas, but it also requires manual insertion of the electric plug into the reserved socket. When the number of bell-type furnaces is large, it will also cause tension in human resources, increased operating costs of the unit, and low heating efficiency. Summary of the Utility Model

[0025] As Figure 1 shown, the present utility model provides a power-taking device for an electric heating bell-type furnace, which includes a brush assembly and a brush base. The brush assembly is connected to the outer cover 2 through an upper connector 1, and the brush base is connected to the furnace platform 4 through a lower connector 3. The brush assembly is lifted and displaced with the outer cover, and comes into contact with the brush base to conduct electricity or separates from the brush base to cut off electricity.

[0026] The brush assembly is fixed on the steel structure of the outer cover, located on the side of the bottom of the outer cover, and travels back and forth between the furnace platforms of the bell-type furnace with the lifting of the outer cover. The brush base is fixedly placed on the horizontal ground along with the steel structure of the furnace platform.

[0027] As Figure 2 shown, the brush assembly includes a brush terminal 5 and a brush conducting block 6. The brush terminals are respectively connected to the upper connector and the brush conducting block through connecting bolts. The connecting bolts between the brush terminals and the upper connector are covered with insulating sleeves 7.

[0028] As Figure 3 shown, the brush base includes a brush base conducting piece 8, a brush base terminal 9, and a spring pressing device. The upper and lower ends of the spring pressing device are respectively connected to the brush base conducting piece and the brush base terminal.

[0029] The brush assembly is fixedly connected to the outer cover through an upper connecting piece. An insulating sleeve separates the steel structure of the outer cover from the brush conducting block in the middle. The brush base is fixedly connected to the steel structure of the furnace platform through a lower connecting piece and is fixed to the ground. Its power source is that the wiring terminal of the brush base is connected to external power. Through the conducting piece of the brush base, it contacts each moving outer cover brush assembly. The brush conducting block contacts the conducting piece of the brush base to conduct electricity, transmits the electricity to the brush wiring terminal, and supplies power to the electric heating element of the outer cover, that is, the power source of the entire electric heating bell-type furnace. The conducting piece of the brush base reduces the alignment difficulty of the contact and power conduction of the brush conducting block, and at the same time increases the contact area of the conducting material, improving the working reliability of the power taking device.

[0030] According to the number of electric heating elements on the outer cover and the power consumption mechanism, the power taking device can be divided into a three-stack type and a six-stack type, which are respectively used for small-power and large-power electric heating bell-type furnaces.

The two ends of the pressing spring are respectively connected to the upper and lower insulating blocks.

[0033] In some alternative implementation schemes, a concave hole is provided at the center of the top of the brush wiring terminal, a connecting bolt is arranged in the concave hole, and a clamping step portion is provided at the bottom of the brush wiring terminal, which is clamped and positioned with the bayonet on the brush conducting block, improving the connection stability between the brush wiring terminal and the brush conducting block.

[0034] In some alternative implementation schemes, the brush conducting blocks are symmetrically arranged on the left and right and are arranged in a V-shaped layout.

At this time, the brush base is powered on through an automatic program, and the power is conducted from the base to the brush and the electric heating element connected to the brush, and the heating and soaking process starts;

[0038] 3. After the annealing process ends, the power supply to the brush base is automatically disconnected through the program, the outer cover is lifted off, and the next stage of annealing begins.
