Description

TECHNICAL FIELD

[0001] The application applies to the technical field of steel ball temperature measurement, and particularly relates to a full-automatic temperature measurement and sorting device for wear-resistant steel balls. BACKGROUND

[0002] The wear-resistant steel ball is a high-alloy special steel, and needs to be quenched by water after heating to improve the hardness of the wear-resistant steel ball, so as to achieve wear resistance and impact resistance. The quenching temperature of the steel ball needs to be controlled very high. The temperature deviation of the forged steel ball before quenching is large, so that the temperature of the quenched steel ball cannot be unified. The quenched treatment is performed by manual detection of the temperature, and the manual cost is high, the efficiency is low, and the stability is poor.

[0075] Reference Figure 1 and Figure 2 , the working principle: the full-automatic temperature-measuring and sorting device for wear-resistant steel balls in this example first sorts and conveys the qualified steel balls 6, and then sorts and conveys the unqualified steel balls 6; specifically, when the eight pusher boxes 232 are all placed with the steel balls 6, the eight infrared temperature detectors 102 respectively detect the temperatures of the steel balls 6 in the corresponding pusher boxes 232, at this time, the infrared temperature detector 102 that detects the qualified temperature transmits a signal to a control mechanism (not shown in the figure), and the control mechanism controls the pusher cylinder 22 and the sorting cylinder 122 of the steel ball with the qualified temperature to work, that is, the sorting cylinder 122 drives the sorting plate 123 to rotate to make the OK channel 14 in communication with the discharge chute 9, and the pusher cylinder 22 of the steel ball with the qualified temperature drives the pusher box 23 to move forward, so as to push the steel balls 6 in the pusher box 232 with the qualified temperature into the discharge chute 9, at this time, the steel balls 6 with the qualified temperature roll into the conveying track connected with the other side of the OK channel 14 through the discharge chute 9 and the OK channel 14; after the sorting and conveying of the steel balls with the qualified temperature are completed, the control mechanism controls the sorting cylinder 122 to drive the sorting plate 123 to rotate to make the NG channel 15 in communication with the discharge chute 9, at this time, the pusher cylinder 22 of the steel ball with the unqualified temperature drives the pusher box 23 to move forward to push the steel balls 6 with the unqualified temperature into the discharge chute 9 and discharge through the NG channel 15, so as to complete the sorting of the steel balls, and finally the control assembly drives the eight pusher cylinders 22 to reset at the same time, and then the next eight steel balls 6 are detected and sorted, and the above actions are repeated. Since the two side walls of the heat insulation cavity 231 are arranged as solid plates, when the pusher box 23 with the qualified temperature is moved forward, if the steel balls 6 in the pusher box 23 adjacent to the pusher box 23 do not pass the temperature detection, the unqualified steel balls 6 will not roll down under the action of the side walls of the heat insulation cavity 231.
