Description

Technical Field

[0001] The utility model relates to the technical field of temperature curve characterization and recording equipment, in particular to a temperature curve characterization and recording device for a hardening furnace. Background Art

[0002] The hardening furnace will be equipped with the simplest temperature control table, and can also view simple temperature record information. With the emphasis on hardening temperature, a visual, continuous and visual temperature record has become a demand. In the prior art, each device of the temperature curve recording device is connected to a temperature control recorder, and the temperature control recorder is connected to a computer. It is impossible to draw curves of different hardening paths, and it is not possible to clearly view the running direction of the curve. It is difficult to find possible abnormal temperatures, and the temperature abnormality cannot serve as a warning to the surrounding personnel. At the same time, the curve recording device lacks an angle adjustment effect, which makes it uncomfortable for some people to use.

[0003] For example, a grinding wheel hardening furnace disclosed in an authorized patent document with application number CN202320387333.9 relates to the field of grinding wheel hardening technology, including a heating cylinder, a base is fixedly provided at the bottom of the heating cylinder, a hardening furnace body is provided inside the heating cylinder, an air suction box is fixedly provided at the top of one side of the heating cylinder, a suction fan is fixedly provided inside the air suction box, and a purification component is fixedly provided at the bottom of the air suction box to achieve adsorption and purification of harmful gases generated by the grinding wheel inside the hardening furnace body during hardening, and a rotating component is fixedly provided on the other side of the heating cylinder to drive the hardening furnace body to rotate so that the grinding wheel inside is heated evenly. The utility model drives the hardening furnace body to rotate by rotating the rotating shaft, thereby realizing uniform rotation of the hardening furnace body, so that a number of heating wires heat it evenly, avoiding uneven heating affecting the subsequent hardening effect and rate, and at the same time, harmful gases are double filtered by the purification component and the filter box to avoid harmful gases being discharged into the environment and causing pollution.

At the same time, the curve depiction and recording device lacks an angle adjustment effect, which makes it uncomfortable for some people to use. Therefore, we need to provide a hardening furnace temperature curve depiction and recording device. Utility Model Content
