Technical Field

[0001] The utility model relates to the technical field of high-frequency welding, in particular to a high-frequency pressing block with a temperature reduction function. Background Art

[0002] High-frequency welding refers to a welding method that uses the resistance heat generated by high-frequency current flowing through the contact surface of the workpieces and applies pressure (or no pressure) to connect the metals of the workpieces. It has the advantages of fast and efficient, simple operation and high welding quality.

[0003] At present, when metal strips are subjected to high-frequency welding, the high-frequency pressing block will generate a large amount of heat during operation, resulting in the high-frequency pressing block having an excessively high temperature, which affects the service life of the high-frequency pressing block. At the same time, the high temperature will also affect the welding part of the metal strip and reduce the welding quality. Therefore, we propose a high-frequency pressing block with a cooling function. Utility Model Content

[0004] The purpose of the utility model is to provide a high-frequency pressing block with a cooling function, which has the advantages of being able to reduce the temperature of the high-frequency pressing block during operation and extend its service life, while also avoiding the influence of high temperature on the welding of metal strips, thereby improving the welding quality, and solving the problem that when the metal strip is currently welded through high-frequency welding, the high-frequency pressing block generates a large amount of heat during operation, resulting in excessively high temperature of the high-frequency pressing block, thereby affecting the service life of the high-frequency pressing block, and at the same time, the high temperature also affects the welding part of the metal strip, thereby reducing the welding quality.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-frequency pressure block with a cooling function, comprising a base and a high-frequency pressure block body, the outer surface of the high-frequency pressure block body is equidistantly provided with three through holes, the three through holes are movably inserted with heat exchange tubes, both ends of the three heat exchange tubes are connected with quick connectors, the outer surfaces of the three heat exchange tubes are provided with threads near the two ends, the outer surfaces of the three heat exchange tubes are movably sleeved with nuts near the two ends, a variable frequency pump is installed in the middle position of the upper surface of the base, and a frequency converter and a cold water tank are respectively installed on both sides of the upper surface of the base.

[0006] Preferably, the six quick connectors are divided into three groups, two by two, wherein the ends of the two quick connectors in the first group are respectively fixedly connected to a water inlet pipe and a water outlet pipe, the end of the water outlet pipe is fixedly connected to the outside of the cold water tank, the end of the water inlet pipe is fixedly connected to the end of the frequency conversion pump input pipe, and the remaining two groups of quick connectors are connected through connecting pipes.

[0009] Preferably, a groove is provided at a middle position on the upper surface of the high-frequency pressing block body, and a temperature sensor is fixedly installed inside the groove.

[0010] Preferably, heat dissipation fins are fixedly mounted on the outer surface of the cold water tank.

[0011] Preferably, a plurality of fixing plates are fixedly installed at equal distances on the bottom and the top of the inner wall of the cold water tank.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model provides a high-frequency pressing block body, a through hole, a thread, a nut, a quick connector, a frequency conversion pump and a heat exchange tube, so as to reduce the temperature of the high-frequency pressing block during operation and extend its service life. At the same time, it also avoids the influence of high temperature on the welding of metal strips and improves the welding quality. The heat exchange tube is inserted into the through hole, nuts are put on both ends of the heat exchange tube, and the nuts at both ends of the heat exchange tube are screwed to fix the heat exchange tube in the through hole. The frequency conversion pump inputs cooling water in the cold water tank into the heat exchange tube and takes away the heat of the high-frequency pressing block body.

[0014] 2. The utility model achieves the effect of accurately controlling the temperature of the high-frequency pressing block by setting a frequency conversion pump and a temperature sensor. The temperature of the high-frequency pressing block body is monitored by the temperature sensor. According to the temperature value, the operating frequency of the frequency conversion pump is adjusted by the frequency converter to control the cooling water flow inside the heat exchange tube, thereby controlling the temperature of the high-frequency pressing block body.

[0015] 3. The utility model achieves the effect of recycling cooling water and reducing water resource consumption through the heat dissipation fins and fixed plates. The cooling water flowing out from the high-frequency pressing block body flows back to the cold water tank through the outlet pipe after heating. The fixed plates on the top and bottom of the inner wall of the cold water tank are staggered, so that the cooling water flowing back to the cold water tank flows up and down in a wave shape. During the flow, the heat in the cooling water is released through the heat dissipation fins on the outer surface of the cold water tank. The cooled water can be recycled after being cooled.
