Servo high frequency heating plug

Abstract

The invention provides a servo high-frequency heating plug, which includes a feeding mechanism, a heating mechanism, a supply mechanism and a hot-plug mechanism for taking materials. The feeding mechanism includes a blowing tube, a feeding tube and a ceramic tube. The feeding mechanism is used to transport metal parts. The metal parts in the ceramic tube are mainly heated by high-frequency heating coils. The drive plate in the supply mechanism is slidably installed on the bottom plate, which effectively shortens the time for the hot metal parts to be outside, reduces the heat loss value, and speeds up the heating of the hot metal parts at the same time. During the transportation process of the parts, there is a cooling port in the retrieving and hot inserting mechanism. After the hot metal parts are inserted into the plastic plate, the compressed cold air can be injected into the cooling port to quickly cool down the hot metal parts to prevent the hot metal parts from being damaged due to excessive temperature. Bulge out of the plastic part.

Description

technical field [0001] The invention relates to the field of heating appliances, in particular to a servo high-frequency heating plug used for hot inserting metal parts (nuts or bushings) into plastic parts after being heated to 350°C by high-frequency heating. Background technique [0002] At present, metal parts (nuts or bushes) are heated by heat conduction. In order to reach the preset temperature and keep up with the production beat, dozens of metal parts need to be heated at the same time. The heating time is about 4-5 minutes. This operation form has the following disadvantages: firstly, the energy loss is high, dozens of metal parts are heated at the same time, and the heat of heating metal parts (nuts or bushings) is too large; secondly, due to the excessive quantity of heating metal parts (nuts or bushings) Too much, it is easy to cause material jams during the process of material distribution and reclaiming; at the same time, metal parts (nuts or bushes) will lose...

[0002] At present, metal parts (nuts or bushes) are heated by heat conduction. In order to reach the preset temperature and keep up with the production beat, dozens of metal parts need to be heated at the same time. The heating time is about 4-5 minutes. This operation form has the following disadvantages: firstly, the energy loss is high, dozens of metal parts are heated at the same time, and the heat of heating metal parts (nuts or bushings) is too large; secondly, due to the excessive quantity of heating metal parts (nuts or bushings) Too much, it is easy to cause material jams during the process of material distribution and reclaiming; at the same time, metal parts (nuts or bushes) will lose part of the heat through material distribution, and then use the hot plug mechanism to reclaim the divided materials, due to heating The mechanism of the metal parts (nut or bushing) and the hot-plug mechanism are two separate mechanisms, and a part is lost during the process of transporting the divided metal parts (nut or bush) to the position where the hot-plug mechanism takes the material Heat, due to the long time spent on distributing and retrieving materials, the temperature of metal parts (nuts or bushings) is unstable, which affects the effect of hot insertion of metal parts (nuts or bushings) into plastic parts
