Embodiment Construction
[0043] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0044] Such as figure 1 As shown, in the method and device embodiment for monitoring the temperature of the guide sleeve or / and guide post of the present invention, the method for monitoring the temperature of the guide sleeve or / and guide post includes the following steps:
[0045] Step S11 Perform analog-to-digital conversion on each input data to obtain a digital signal: In this step, the data representing the current temperature value is obtained from the temperature sensor installed on the guide sleeve or guide post, and the data is modulo-digitized Transform to obtain the numerical signal corresponding to these data. Generally speaking, the resistance of the temperature sensor changes at different temperatures, so that the output current or voltage changes. According to this change, if the temperature characteristics of the temperature sensor are ...

The invention relates to a method for monitoring the temperature of a guide sleeve or / and a guide post, comprising the following steps: respectively obtaining a plurality of data representing the current temperature of the guide sleeve or / and guide post; A set of preset values are compared one by one, and the preset value closest to the obtained data participating in the comparison is selected for each comparison; it is judged whether the selected preset value is greater than the first set value, such as greater than or equal to the first set value A set value, output an alarm control signal and execute the next step; if it is less than the first set value, execute the next step; take out the drive signal corresponding to the selected preset value and output it. The invention also relates to a device for implementing the above method. Implementing the method and device for monitoring the temperature of the guide sleeve or / and guide post of the present invention has the following beneficial effects: the temperature value of each guide sleeve or / and guide post can be effectively displayed and the operator is reminded to pay attention when the temperature exceeds the set range .
Description
technical field [0001] The invention relates to the field of molds, more specifically, to a method and device for monitoring the temperature of a guide sleeve or / and a guide post. Background technique [0002] For general formwork, guide sleeves and guide posts must be used. Usually, the guide bush and the guide post are used together. When the mold is closed, the guide post arranged on the mold is inserted into the guide sleeve, thereby playing the role of positioning and guiding, which is conducive to the smooth opening and closing of the mold. Although the processing accuracy of the guide bush and the guide post and the accuracy of the setting position are very important items in the process of processing and installing the guide bush and the guide post, but in the actual product, there will always be some situations that make the above guide post Friction occurs with the guide sleeve when the mold is opened and closed. The friction during the mold opening and closi...
