Problems solved by technology

[0004] One type is paper records plus electronic data, and then convert the data into EXCEL software for calculation, and judge whether it is within the allowable range according to the calculation of the heating rate value or cooling rate value at each moment, but the method of calculating through EXCEL software Is cumbersome and time-consuming, and is only used for devices that can record electronic data during the curing process
[0005] The other type is to manually calculate the heating rate or cooling rate through paper file records, and judge whether the temperature change rate of the part is within the allowable range through the value of the heating rate or cooling rate. Since the time points recorded in paper files are discrete It is not continuous, so the method of calculating the temperature change rate through paper file records cannot accurately calculate the heating rate or cooling rate at any time
[0006] Therefore, for the detection method of the temperature change rate of the workpiece by using software, the calculation is cumbersome and time-consuming, and electronic equipment that requires specific recording data, and for the calculation of the temperature change rate of the workpiece by using paper file recording data. The temperature change rate at discrete time points can be calculated, but the temperature change rate at any continuous time point cannot be calculated. The invention discloses a temperature change rate detection method during the curing process of a part.

Abstract

The invention discloses a temperature change rate detection method in a workpiece curing process. The temperature change rate detection method comprises the following steps: 1, acquiring a temperaturechange rate range in the workpiece curing process; 2, drawing a temperature change rate range area on the rate inspection sample plate according to the temperature change rate range; 3, detecting theactual temperature change-time curve of the workpiece through a rate inspection template, and if the slope tangent line of a certain point on the actual temperature change-time curve is located in the temperature change rate range area, qualifying the temperature change rate of the point at the moment corresponding to the point; detecting any point on the actual temperature change-time curve through the rate detection plate, visually and conveniently obtaining whether the temperature change rate of the workpiece at the corresponding time point reaches the standard or not, and detecting the temperature change rate of the workpiece at any continuous time point.

Description

technical field [0001] The invention belongs to the technical field of temperature change rate detection of workpieces, and in particular relates to a temperature change rate detection method in the curing process of workpieces. Background technique [0002] A variety of parts need to be cured by heating in an oven or autoclave, and these heating devices can record the curing temperature of the part over time. During the entire curing process, the heating rate or cooling rate of the workpiece has a strict control range. Too fast or too slow a temperature change rate will have a serious impact on the quality of the workpiece itself. It is possible to cause the entire part to be scrapped. Therefore, it is necessary to judge whether the heating rate or cooling rate of the cured parts meets the standard according to the curing data at each moment. The calculation method of heating rate or cooling rate is (temperature 1-temperature 2) / time. [0003] Existing general-purpose he...
