Description

Technical Field

[0001] The utility model belongs to the field of diamond cutting wire manufacturing, in particular to a tungsten wire surface lubricating layer drying device. Background Art

[0002] In the field of metal processing and surface treatment, tungsten wire, as an important material, is widely used in various high-temperature and high-load working environments. Diamond cutting wire, as a key tool in modern high-precision cutting technology, is widely used in the cutting of various hard materials. Among them, tungsten wire, as an important component of diamond cutting wire, is subjected to extremely high temperature and friction, so the requirements for its surface performance are also extremely strict.

[0003] In the production process of diamond cutting wire, tungsten wire needs to continuously and stably transmit cutting force and produce friction with the material being cut. In order to improve its wear resistance and work efficiency, a layer of graphite emulsion is usually coated on the surface of tungsten wire as a lubricating layer. With its excellent lubrication performance and high temperature resistance, graphite emulsion can effectively reduce the friction coefficient between tungsten wire and the material being cut, reduce energy loss, and improve cutting efficiency. Graphite emulsion has good lubrication performance and high temperature resistance, which can significantly improve the service life and work efficiency of tungsten wire.

[0004] However, in practical applications, the traditional tungsten wire coating process often ignores the drying of the graphite emulsion. Without the drying step, the graphite emulsion cannot be completely solidified. It is not only easy to fall off during the cutting process, affecting the cutting quality and stability, but also it is impossible to achieve secondary coating of the tungsten wire, thus limiting the thickness of a single coating. The weak lubricating layer cannot withstand long-term high-intensity friction, resulting in increased wear of the tungsten wire and shortened service life. At the same time, it is impossible to coat different types of graphite emulsions on the surface of the tungsten wire to meet different production needs. Utility Model Content

[0005] The utility model aims to provide a tungsten wire surface lubricating layer drying device to solve the technical problems of easy falling off of graphite emulsion layer and low single coating thickness in the existing process, and inability to coat different graphite emulsions.

[0006] In order to achieve the above-mentioned purpose, the specific technical scheme of a tungsten wire surface lubricating layer drying device of the utility model is as follows:

[0007] A tungsten wire surface lubricating layer drying device comprises a hollow drying structure for the tungsten wire to pass through, a heat supply structure connected to the drying structure, and a bracket for supporting the drying structure;

[0008] The inner surface of the hollow structure of the drying structure is provided with a plurality of heat supply holes, and the heat supply holes send out heat to dry the surface of the tungsten wire passing through the drying structure.

[0009] As a further improvement of the present invention, the bracket includes a support seat for placing the drying structure, a support rod connected to the lower end of the support seat, and a base connected to the lower end of the support rod.

[0010] As a further improvement of the present invention, the support rod is telescopically connected to the base, and the height of the support seat is adjusted by adjusting the telescopic degree of the support rod relative to the base.

[0011] As a further improvement of the present invention, the drying structure is a tubular hollow structure with an open upper end, and the heat delivery holes are arranged in an array on the surface of the hollow structure.

[0012] As a further improvement of the present invention, the support seat is a clamping structure that opens upward, and the drying structure is inserted into the opening and then clamped on the support seat.

[0013] As a further improvement of the utility model, the heat delivery structure delivers natural gas to the heat delivery hole.

[0014] As a further improvement of the utility model, an ignition device is provided in the hollow structure, and natural gas is ignited in the hollow structure to dry the tungsten filament.

[0015] As a further improvement of the present invention, the drying structure is provided with a temperature sensor to monitor the drying temperature.

[0016] As a further improvement of the utility model, the heat delivery structure is provided with a regulating valve, and the regulating valve controls the flow rate of the natural gas according to the temperature information fed back by the temperature sensor.

[0017] As a further improvement of the utility model, the outer shell of the drying structure is provided with a heat insulation layer to reduce heat loss; the heat insulation layer is made of high temperature resistant heat preservation material.

[0018] Beneficial effects:

[0019] The drying device of the utility model effectively solves the problem that the graphite emulsion cannot be firmly attached in the traditional coating process. By accurately controlling the drying temperature and time, the graphite emulsion is ensured to be uniformly solidified on the surface of the tungsten wire to form a tough and durable lubricating film. This not only improves the adhesion of the lubricating layer, but also enhances its wear resistance and high temperature resistance, thereby significantly extending the service life of the tungsten wire.

[0020] By using the drying device, multiple coatings of tungsten wire can be achieved, effectively increasing the thickness of the lubricating layer. Traditional single coating is difficult to achieve multiple superpositions due to the weak lubricating layer. The application of this drying device makes multiple coatings possible, and different types of graphite emulsions are coated each time, thereby improving the lubrication performance of the tungsten wire surface and further improving the cutting efficiency and stability of the diamond cutting wire.

[0021] In summary, the application of the tungsten wire surface lubricating layer drying device of the utility model not only improves the surface performance and service life of the tungsten wire, but also promotes the progress of diamond cutting wire technology and has a positive impact on the development of the hard material processing field. At the same time, its convenient operation, high efficiency and energy saving also make the device have a wide range of application prospects in the market. BRIEF DESCRIPTION OF THE DRAWINGS

The base 33 is provided with an upwardly protruding socket 34, and the socket 34 and the support rod 32 are provided with corresponding limited holes 35. After the support rod 32 is inserted into the socket 34, it is fixed by bolts passing through the corresponding limited holes 35, and the upward protrusion of the support rod 32, that is, the height of the support seat 31, is adjusted. Fixing holes 36 are provided on both sides of the C-shaped support seat 31, and bolts pass through the fixing holes 36 to abut against the drying structure 10, so that the drying structure 10 is clamped and fixed in the support seat 31.
