Description

Technical Field

[0001] The invention relates to the technical field of tungsten wire drawing processing, in particular to a tungsten wire surface graphite emulsion drying mechanism. Background Art

[0002] Tungsten wire drawing equipment is a device used to draw thick tungsten wire (tungsten wire raw material) into thin tungsten wire of required diameter through a drawing die. Before the tungsten wire passes through the drawing die, it needs to pass through graphite emulsion. When the tungsten wire passes through the graphite emulsion (graphite emulsion is a graphite powder suspension), the surface of the tungsten wire will be covered by the graphite emulsion. After that, when it passes through the drying equipment, the water in the graphite emulsion evaporates, and the graphite powder is evenly attached to the surface of the tungsten wire. After that, when it passes through the drawing die, the graphite powder plays a lubricating role. In the prior art, the tungsten wire after being soaked in graphite emulsion passes directly through the gap between the two heating plates. All the tungsten wires are heated and dried synchronously through the heating gap, so that the graphite emulsion on the surface of the tungsten wire is dried. Due to the simultaneous drying of multiple tungsten wires, there are differences in temperature in different areas of the heating gap, which leads to uneven drying, thereby affecting the subsequent drawing quality. Summary of the Invention

[0003] In order to solve the above problems existing in the prior art, the present invention provides a tungsten wire surface graphite emulsion drying mechanism which is easy to use and can heat more stably and evenly.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A tungsten wire surface graphite emulsion drying mechanism comprises a box body with an open upper end, a cover body provided at the opening of the box body, and a plurality of parallel distributed heating components provided in the box body; the heating components comprise a heat conducting tube and a plurality of electric heating tubes provided in the heat conducting tube, the cross section of the heat conducting tube presenting a C-shaped structure, a wire feeding notch provided on the upper side of the heat conducting tube, a C-shaped cavity penetrating both ends of the heat conducting tube provided in the heat conducting tube, end caps provided at both ends of the C-shaped cavity, the electric heating tube provided in the C-shaped cavity and the ends of the electric heating tube respectively connected to the end caps; avoidance notches are provided on the box body at positions corresponding to the two ends of the heat conducting tube.

[0006] Open the cover and insert the tungsten wire into the heat pipe from the wire inlet notch. The tungsten wire is located at the center of the heat pipe. Close the cover and heat the electric heating tube to dry the graphite emulsion on the surface of the tungsten wire. Each tungsten wire is heated by an independent heating component, making the heating more uniform and stable.

[0007] Preferably, the box body is provided with a lower heat insulation layer, and the top surface of the lower heat insulation layer is provided with a plurality of lower arc grooves for installing heat pipes. The lower heat insulation layer plays a heat insulation role, reduces heat loss of the heat pipes, and improves heat energy utilization.

The heat insulation gap further improves the heat insulation performance and reduces heat loss of the heating component.

[0009] Preferably, the lid is hingedly connected to the box body, and is provided with an upper thermal insulation layer. The lower side of the upper thermal insulation layer is provided with a plurality of upper arcuate grooves corresponding to the lower arcuate grooves. When the lid is placed on the box body, the upper arcuate grooves engage the outer sides of the heat conducting tubes and seal the wire inlet opening. The hinged connection between the lid and the box body makes opening and closing the lid more convenient, and the upper thermal insulation layer provides thermal insulation, reducing heat loss from the lid.

[0010] Preferably, the heat pipe is provided with connectors at both ends of its lower side, each connector having a connecting post, the lower end of which is provided with a thread, and the lower end of the connecting post is passed through the heat insulation board and locked with a nut. The connecting post is used for installation and positioning of the heat pipe.

The connecting bases facilitate installation of the box body, and after the connecting ears are connected to the rack, the bottom surface of the box body and the rack are not in contact, thereby reducing heat transfer to the rack.
