Description

Technical Field

[0001] The utility model relates to a circuit docking couple for plugging circuits of an annealing furnace and a capacity expansion furnace, belonging to the technical field of circuit docking. Background Art

[0002] Annealing furnaces are used to heat and anneal workpieces. Existing annealing furnaces are of fixed size, but their drawback is that large annealing furnaces are expensive. Generally, large workpieces processed by processing companies have different lengths. If companies purchase them based on the largest specifications, they waste a lot of electricity when processing shorter workpieces. If they purchase them based on the shortest specifications, they cannot process longer workpieces. If they purchase them based on all specifications, the purchase cost increases several times and they also occupy a large area of space. Our company aims to solve the above problems, but solving these problems involves connecting circuits between two electricity users with the same power demand. Conventional methods require manually plugging and unplugging each circuit one by one, which is time-consuming and labor-intensive. Automatically connecting circuits based on the close connection between the two train phases requires excessive precision and seems unnecessary. Utility Model Content

[0020] The present invention will be further described below with reference to the embodiments and accompanying drawings:

[0021] like Figure 1 、 4As shown, the technical improvement scheme involved in this application is to set up an expansion furnace 200 in front of the annealing furnace 100. When annealing and heating a workpiece whose length exceeds the depth of the annealing furnace 100, the expansion furnace 200 is docked close to the annealing furnace 100 to increase the depth of the annealing furnace 100 cavity so that it can accommodate the lengthened workpiece. Since the annealing furnace 100 adopts electric heating for annealing, the added expansion furnace 200 also needs to be equipped with a corresponding electric heating method. Therefore, it is necessary to ensure that at least a heating power supply is provided to the expansion furnace 200. If it is necessary to monitor the interior of the expansion furnace 200 cavity, the sensor signal circuit must also be connected.

[0022] like Figure 1 As shown in FIG. 4 , a circuit docking couple for connecting the circuits of an annealing furnace and an expansion furnace comprises a power supply socket 1 and a power receiving socket 2 respectively provided on the annealing furnace 100 and the expansion furnace 200. The power supply socket 1 is provided with a plurality of conductive plug tubes 11 for connecting to the power supply circuit, and the power receiving socket 2 is provided with a plurality of conductive plug posts 21 for connecting to the power circuit. Each conductive plug post 21 corresponds to a conductive plug tube 11 that can be inserted. There is a safety interval between each conductive plug post 21 and each conductive plug tube 11 to prevent current short circuit. The corresponding conductive plug posts 21 and conductive plug tubes 11 are located on the same axis. During use, as the expansion furnace 200 gradually approaches the annealing furnace 100 for docking, each conductive plug post 21 is aligned with the corresponding conductive plug tube 11 and inserted, thereby achieving circuit connection between the annealing furnace 100 and the expansion furnace 200. When the expansion furnace 200 is separated from the annealing furnace 100, each conductive plug post 21 is pulled out of the corresponding conductive plug tube 11. In this way, there is no need to manually plug in and unplug the corresponding various circuits, which can simplify the docking operation of the annealing furnace 100 and the capacity expansion furnace 200.

[0023] like Figure 3 As shown, the power socket 1 includes a seat frame 12 fixed to the annealing furnace 100, a plurality of conductive plug tubes 11 are provided in the middle area of the seat frame 12, and an elastic filling body 13 with a set stiffness is provided in the seat frame 12 and between the conductive plug tubes 11. Preferably, the elastic filling body 13 is a rubber body. It is further preferred that the rubber body is filled in the seat frame 12 in a vulcanized manner so that the seat frame 12 and the conductive plug tubes 11 are solidified into one. In this way, the rubber body has both an insulating effect and can be deformed under strong force. When the conductive plug post 21 is inserted into the conductive plug tube 11, if there is a slight deviation, the conductive plug post 21 can be forced to make a corresponding offset through the deformation of the rubber body, so that the conductive plug post 21 can be smoothly inserted into the conductive plug tube 11.

[0024] like Figure 2 As shown, the end of the conductive plug post 21 is tapered to facilitate insertion into the conductive plug tube 11 . In this way, the end of the conductive plug post 21 can form a cone tip to guide the insertion into the conductive plug tube 11 .

[0025] The conductive plug pins 21 are divided into a heating power plug pin 211 and a signal power plug pin 212. Correspondingly, the conductive plug tube 11 is divided into a heating power plug tube 111 and a signal power plug tube 112. The diameter of the heating power plug pin 211 is larger than the diameter of the signal power plug pin 212, and the length of the heating power plug pin 211 is longer than the length of the signal power plug pin 212. Because the heating power plug pin 211 is relatively large, the length of the heating power plug pin 211 is designed to be longer than the length of the signal power plug pin 212. This allows the heating power plug pin 211 to be inserted into the corresponding heating power plug tube 111 first. When the heating power plug pin 211 is inserted into the corresponding heating power plug tube 111, it and the signal power plug pin 212 are basically aligned with their respective signal power plug tubes 112.

[0026] Attachment Figure 3 、 4 The figure shows a heating circuit line 1111 connected to the heating power plug tube 111 and a signal circuit line 1121 connected to the signal power plug column 212.

[0027] like Figure 2 As shown, an insulating layer 213 is provided at least at the root of the heating power supply plug-in column 211. Its function is to prevent the heating power supply with a strong current and a high voltage from breaking through the air at the root of the heating power supply plug-in column 211 and causing a short circuit after the heating power supply plug-in column 211 is inserted into the corresponding conductive plug-in tube 11 and energized.

[0028] The above embodiments are only used to more clearly describe the present invention and cannot be regarded as limiting the scope of protection covered by the present invention. Any modifications in equivalent forms should be regarded as falling within the scope of protection covered by the present invention.
