[CN 201720151224.1] Electrical Device for Preventing Travel of Light Mechanical Press
[CN 201720151224.1] Title of Electrical Device for Preventing Travel Connection of Light Mechanical Press: Application Number of Electrical Device for Preventing Travel Connection of Light Mechanical Press: CN 201720151224.1 Applicant: First Tractor Co., Ltd. Application Date: 2017-2-20 Patent Type: Utility Model Electrical Device for Preventing Travel Connection of Light Mechanical Press, Including: control power air switch, foot switch, time relay delay contact, contactor, time relay, contactor normally open contact A, electromagnet coil, contactor normally open contact B; The time relay delay contact and contactor are connected in series, connected in parallel with the time relay, and then connected in series with the foot switch to form the first circuit. After the contactor normally open contact A, electromagnet coil and contactor normally open contact B are connected in series to form the second circuit, then it is connected in parallel with the first circuit, and the air switch of the control power supply is used as the main switch to connect the two circuits to form the total control circuit. This device can make the light mechanical press use the foot switch in the process of operation, prevent the phenomenon of equipment connection caused by the foot switch not being released in time, and ensure the safety of the operator and the mold. The test has proved that the effect is good and achieves The purpose of controlling this kind of car connection phenomenon.
