[0002] The diamond wire produced by using tungsten wire as the busbar is widely used in the cutting of silicon wafers due to its high strength, corrosion resistance, and fatigue resistance characteristics, and plays an extremely important role in the photovoltaic industry, with good market value. During the drawing process of tungsten wire, it is necessary to heat the tungsten wire through a heating device to soften it, and then draw it to the required fineness through a die opening while it is hot.

[0003] In the prior art, the heating device is fixedly installed on the wire drawing machine and is generally provided with a heat preservation cover, and the heat preservation cover uses a flip structure or a push-pull structure to cover the heating device; when a group of tungsten wires are drawn, it is necessary to open the heat preservation cover to replace another group of tungsten wires. However, since the heat preservation cover is opened by using a flip or push-pull structure, the heat inside the heating device will quickly escape, and then it is necessary to wait for the temperature inside the heating device to rise, resulting in slow drawing effect of tungsten wire and large energy consumption during the drawing process. Therefore, it is necessary to design a new wire drawing machine heating device to solve the above problems. Summary of the Utility Model

Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] Please refer to Figures 1 to 4 , a furnace disk structure of a diamond busbar wire drawing machine, including a furnace disk body 100. A heating space 110 is provided at the front end of the furnace disk body 100. The heating space 110 makes the cross-section of the furnace disk body 100 form a 'C'-shaped structure. One side of the heating space 100 is a wire inlet 120, and the other side is a wire outlet 130. A closing door body 200 is provided on the furnace disk body 100. The closing door body 200 is used to open / close the opening of the heating space 110. The furnace disk body 100 is also provided with a heating groove 300. The heating groove 300 is located below the heating space 110, and a heating pipe 310 is laid in the heating groove 300.

[0027] Specifically, in this embodiment, a heating space 110 is opened at the front end of the furnace plate body 100, so that the cross-section of the furnace plate body 100 is in a 'C'-shaped structure through the heating space 110. At the same time, a closing door body 200 is arranged at the opening of the heating space 110. When the tungsten wire needs to be drawn, the closing door body 200 at the opening of the heating space 110 is opened, and the tungsten wire drawn back and forth is put in from the opening of the heating space 110, so that the tungsten wire is drawn in sequence from the wire inlet 120 to the wire outlet 130. After putting it in, the closing door body 200 is directly closed, and the heating tube 310 in the heating tank 300 is heated until the heating condition is met to realize the drawing of the tungsten wire. Since the closing door body 200 is in a closed state during the drawing process of the tungsten wire, the temperature loss in the heating space 110 can be effectively reduced to ensure the wire drawing quality; when one coil of tungsten wire is drawn, a new tungsten wire coil needs to be replaced. At this time, the closing door body 200 is opened again, and the new tungsten wire is put in from the opening of the heating space 110. After putting it in, the closing door body 200 is quickly closed, so as to avoid opening the whole furnace plate body 100 and reduce the temperature loss inside the heating space 110. Since the temperature loss inside the heating space 110 is small, the heating temperature inside the heating space 100 can reach the set temperature quickly, thereby reducing energy consumption and improving the drawing efficiency of the tungsten wire.

[0028] In addition, since the furnace plate structure in this embodiment is installed on the wire drawing machine and is located between the wire feeding mechanism and the wire drawing mechanism, the thick tungsten wire of the wire feeding mechanism enters the heating space 110 from the wire inlet 120 of the furnace plate body 100 and is drawn to the wire drawing mechanism from the wire outlet 130 of the furnace plate body 100. In order to fixedly install the furnace plate body 100, a mounting bracket 600 is arranged at the rear end of the furnace plate body 100. A plurality of mounting brackets 600 are provided, and the furnace plate body 100 can be fixedly installed on the wire drawing machine through the mounting brackets 600. At the same time, the positive and negative electrodes of the heating tube 310 can extend from the rear end of the furnace plate body 100 and are supported and fixed by the mounting brackets 600, so that the furnace plate structure is reasonably designed.

[0029] Of course, in order to better achieve the heat preservation effect of the furnace plate body 100, the outer wall of the furnace plate body 100 is made of stainless steel material, and a heat preservation layer 500 is filled inside the furnace plate body 100. The heat preservation layer 500 can effectively reduce the temperature loss inside the heating space 110, so as to ensure the heating effect.

[0030] In this embodiment, in order to monitor the temperature in the heating space 110 in real time, the furnace plate body 100 further has a temperature sensor 400. The temperature sensor 400 extends from the bottom of the furnace plate body 100 into the heating tank 300. Through the temperature sensor 400, the temperature in the heating space 110 can be monitored in real time to ensure that the temperature of the heating space 110 reaches the required temperature when drawing tungsten wire.

[0031] Finally, in order to realize the opening / closing of the closing door body 200, the closing door body 200 in this embodiment includes a support block 210, a driving handle 220 and a door panel 230. The support block 210 is arranged on the top of the furnace plate body 100. The middle part of the driving handle 220 is rotatably connected to the support block 210, and the door panel 230 is movably connected to one end of the driving handle 220 through a connecting column 240.

[0032] When opening / closing the closing door body 200, the worker presses the driving handle 220 downward. The driving handle 220 swings around the rotation connection with the support block 210. When swinging, the door panel 230 is lifted upward through the connecting column 240. At this time, the closing door body 200 is opened. When the worker releases the driving handle 220, under the drive of the weight of the door panel 230 itself, the door panel 230 will drop downward, thereby closing the opening of the heating space 110 to avoid excessive loss of the temperature in the heating space 110.

[0033] In order to ensure that the door panel 230 can smoothly drop to close the opening of the heating space 110, a counterweight 250 is connected to the side of the door panel 230, and the bottom of the counterweight 250 is flush with the bottom of the door panel 230. Through the counterweight 250, the weight of the door panel 230 itself can be increased, so that the door panel 230 can smoothly drop downward to close the opening of the heating space 110, and the counterweight 250 can thicken the door panel 230, thereby effectively avoiding the loss of the temperature inside the heating space 110 to the outside.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry can smoothly implement the present invention according to what is shown in the description drawings and what is described above; however, any slight changes, modifications and equivalent changes made by those skilled in the art in the scope of the technical solution of the present invention by using the technical content disclosed above are equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments according to the essence of the present invention still fall within the scope of the technical solution protection of the present invention.
