Description

TECHNICAL FIELD

[0002] In modern industrial production, the cutting processing of magnetic material is a crucial link, which is widely used in electronic, electric power, communication and many other fields. With the continuous improvement of the precision requirement of magnetic material products and the continuous growth of market demand, multi-wire cutting machine emerges as the times require and becomes the mainstream processing equipment.

[0003] Multi-wire cutting machine realizes high-precision slicing operation on magnetic material through high-speed moving cutting wire and cutting fluid. Among them, the guide wheel as the key component of bearing and driving cutting wire high-speed operation plays an important role. In the actual cutting process, the guide wheel needs to keep high-speed rotating state for a long time. Due to the existence of violent friction between cutting wire and guide wheel and the mechanical loss caused by high-speed operation, a large amount of heat will be generated. If these heat cannot be dissipated in time, it will be gathered in the inside and surface of the guide wheel. On the one hand, high temperature will cause the physical properties of the guide wheel material to change, for example, the strength is reduced and the hardness is softened, thus accelerating the wear of the guide wheel and shortening its normal service life; on the other hand, too high temperature may also affect the tension stability of the cutting wire, causing the cutting precision to decrease, and ultimately affecting the quality of the product.

Timely heat dissipation avoids the strength reduction and hardness softening of the guide wheel due to high temperature, thus greatly reduces the wear of the guide wheel, significantly prolongs the service life of the guide wheel, and reduces the frequency and cost of guide wheel replacement in equipment maintenance. Good heat dissipation effect ensures that the working temperature of the guide wheel is stable, and avoids the unstable tension of the cutting wire caused by high temperature.

[0020] Compared with the prior art, the utility model has the beneficial effects that:

[0021] The magnetic material multi-wire cutting machine provided by the application effectively solves the problem of physical property change of the material caused by heat accumulation when the guide wheel rotates at high speed for a long time. Timely heat dissipation avoids the decrease of the strength and the softening of the hardness of the guide wheel due to high temperature, thereby greatly reducing the wear of the guide wheel, significantly prolonging the service life of the guide wheel, and reducing the frequency and cost of replacement of the guide wheel in equipment maintenance. The good heat dissipation effect ensures the stable working temperature of the guide wheel, and avoids the instability of the cutting wire tension caused by high temperature.

EMBODIMENT

[0038] Please refer to Figures 1-7 A magnetic material multi-wire cutting machine, comprising: a machine body 2 and a guide wheel 3 arranged on a cutting machine frame 1, the guide wheel 3 is supported on the cutting machine frame 1 through a support seat 4;

[0039] Wheel body base 5 is arranged at the bottom of guide wheel 3, and a cavity is arranged inside wheel body base 5;

[0040] Cooling pipe 6 is arranged in the cavity of wheel body base 5, and is used for conveying cooling liquid.

[0041] The magnetic material multi-wire cutting machine of the present application is mainly composed of cutting machine frame 1, machine body 2, guide wheel 3, wheel body base 5, cooling pipe 6, liquid inlet 601 and liquid outlet 602 and other components, and the following is the detailed structure and working principle.

[0042] I. Equipment assembly

[0043] Wheel body base 5 related component installation

[0044] Firstly, cooling pipe 6 is placed in the cavity of wheel body base 5. Cooling pipe 6 is a tubular unit arranged at equal intervals, one end is provided with liquid inlet 601, and the other end is provided with liquid outlet 602, liquid inlet 601 faces upward, and liquid outlet 602 faces downward. Liquid inlet 601 is clamped in first slot 502 opened at one end of wheel body base 5 from top to bottom, and liquid outlet 602 is clamped in second slot 503 opened at the other end of wheel body base 5 from top to bottom, to ensure the stable installation of cooling pipe 6 in the cavity of wheel body base 5.

[0045] Then, cover plate 501 is covered on the opening of wheel body base 5, and clamping plates 5010 at the bottom of cover plate 501 are clamped in the corresponding slots of wheel body base 5 to fix cover plate 501. The material of cover plate 501 can be selected as aluminum alloy with good heat conduction performance, which can effectively transfer heat and has certain strength and corrosion resistance, and it is provided with an arc matched with the bottom of guide wheel 3 to ensure the best heat transfer area with the bottom of guide wheel 3, and at the same time, it does not contact the bottom of guide wheel 3, which does not affect the normal operation of guide wheel 3 and other structures.

[0046] Wheel body base 5 and bottom plate 7 are connected

[0047] Bottom plate 7 is installed below wheel body base 5. Stable screw 504 is arranged at the four corners of the bottom of wheel body base 5, stable screw 504 is inserted into positioning slot 7010 opened at the four corners of the top of bottom plate 7, then support sleeve 505 is connected to stable screw 504 outside through threads, and support sleeve 505 is supported outside the periphery of positioning slot 7010. By rotating support sleeve 505, the height of support sleeve 505 on stable screw 504 can be adjusted, so that the height of wheel body base 5 to guide wheel 3 can be adjusted to adapt to the heat dissipation requirements of different guide wheels 3.

[0048] The front and rear ends of the bottom plate 7 are connected with plug-in plates 701, which are slidably plugged into the plug-in slots 401 of the support seat 4, so as to complete the installation of the bottom plate 7 and the whole structure thereon.

[0049] Whole equipment installation

[0050] The machine body 2 and the guide wheel 3 are arranged on the cutting rack 1, the guide wheel 3 is supported on the cutting rack 1 through the support seat 4, and the guide wheel 3 is above the wheel body base 5, so that there is a proper distance between the guide wheel 3 and the wheel body base 5, so as to meet the heat dissipation requirement and not affect the normal operation of the guide wheel 3.

[0051] II. Equipment use

[0052] Cooling liquid addition and circulation If an external circulation system is connected

[0053] When the guide wheel 3 needs to be cooled, the sealing plug 6010 at the opening of the liquid inlet 601 and the liquid outlet 602 is opened, and the cooling liquid is added into the cooling pipe 6 through the upward liquid inlet 601. The cooling liquid flows in the cooling pipe 6, and since the cooling pipe 6 is arranged at equal intervals in the cavity of the wheel body base 5 and close to the bottom of the guide wheel 3, it can exchange heat with the bottom of the guide wheel 3 and absorb the heat generated by the high-speed rotation of the guide wheel 3.

[0054] If an external circulation system is connected, the cooling liquid can flow out of the liquid outlet 602 after absorbing heat, enter the circulation system for cooling treatment, and then enter the cooling pipe 6 from the liquid inlet 601 through the circulation system, so as to realize the circulation of the cooling liquid and continuously cool the guide wheel 3.

[0055] When the cooling system is not used, the sealing plug 6010 is used to reseal the liquid inlet 601 and the liquid outlet 602 to prevent dust and other impurities from entering the inside of the cooling pipe 6.

[0056] Working principle:

[0057] The guide wheel 3 is a key component for bearing and driving the high-speed running of the cutting wire. Its working state is crucial. There is continuous and intense friction between the cutting wire and the guide wheel 3, which generates a large amount of heat. At the same time, the high-speed running of the guide wheel 3 itself also causes certain mechanical losses, which are also manifested in the form of heat. If these heat cannot be dissipated in time, they will accumulate inside and on the surface of the guide wheel 3. This will make the guide wheel 3 more prone to wear, the originally precise surface roughness will deteriorate, and then affect the running track and tension stability of the cutting wire. Unstable cutting wire tension will directly lead to a decrease in cutting precision, uneven thickness of the cut magnetic material sheet, and poor surface quality, which cannot meet the production requirements of high precision, ultimately affecting the quality and performance of the product, reducing production efficiency, and increasing production cost.

[0058] When the guide wheel 3 generates heat, the heat will be transferred to the surrounding in the form of heat conduction. Since the wheel body base 5 is arranged near the bottom of the guide wheel 3, and the cover plate 501 has good heat conduction performance such as aluminum alloy material, its thermal conductivity is high, and it can quickly conduct heat. The heat will first be transferred to the cover plate 501. The arc-shaped design of the cover plate 501 is adapted to the bottom of the guide wheel 3, which increases the contact area with the guide wheel 3, and is beneficial to more efficiently receiving the heat transferred by the guide wheel 3.

[0059] Then, the heat is transferred from the cover plate 501 to the wheel body base 5, and the cooling pipe 6 inside the wheel body base 5 is in close contact with the wheel body base 5. The cooling pipe 6 is usually made of a material with good heat conductivity, such as copper or aluminum, which can quickly absorb the heat transferred by the wheel body base 5. The cooling liquid inside the cooling pipe 6, such as a special industrial cooling liquid, has a high specific heat capacity and thermal conductivity, can absorb and carry away a large amount of heat, and exchanges heat with the pipe wall of the cooling pipe 6, so that the temperature of the cooling liquid rises, thereby carrying away the heat generated by the guide wheel 3.

[0060] If the cooling liquid is circulated by an external circulation system

[0061] In an ideal heat dissipation design, if an external circulation system is connected, the cooling liquid will flow out from the outlet 602 of the cooling pipe 6 after absorbing heat. The high-temperature cooling liquid enters the circulation system, which may include a heat sink, a pump, and other components. The heat sink dissipates the heat of the cooling liquid to the surrounding environment through air cooling or water cooling, so that the temperature of the cooling liquid decreases.

[0062] The cooled liquid after cooling enters the cooling pipe fitting 6 again through the pipeline from the liquid inlet 601 under the action of the pump, forming a continuous circulation process. In this way, the cooling liquid continuously circulates in the cooling pipe fitting 6, continuously absorbs the heat generated by the guide wheel 3, and takes out the heat, thereby effectively reducing the temperature of the guide wheel 3, keeping the guide wheel 3 working in a relatively stable temperature range, ensuring that its physical and mechanical properties are not affected by high temperature, and maintaining the stability of the cutting line tension and cutting precision.

[0063] The bottom plate 7 arranged below the wheel body base 5 and the height adjustment function realized by the stabilizing screw rod 504 and the support sleeve 505 are of great significance to the optimization of the heat dissipation effect. In actual work, the heat generation of the guide wheel 3 under different models or working conditions may be different. By rotating the support sleeve 505 to adjust the height of the wheel body base 5 to the guide wheel 3, the distance between the guide wheel 3 and the cooling pipe fitting 6 can be changed, and then the efficiency of heat conduction and the heat dissipation effect can be adjusted. For example, when the guide wheel 3 generates more heat, the distance between the wheel body base 5 and the guide wheel 3 can be appropriately reduced, so that the heat is transferred to the cooling pipe fitting 6 more quickly; when the heat generation is relatively light, the distance can be appropriately increased to avoid excessive heat dissipation leading to energy waste or other potential problems. This height adjustability enables the heat dissipation device to better adapt to different working conditions, ensuring that the guide wheel 3 is always in the best working temperature state, and improving the working stability and reliability of the entire multi-wire cutting machine.

[0064] In addition, the design of the plug-in plate 701 at the bottom of the bottom plate 7 slidingly plugged into the slot 401 on the support seat 4 not only realizes the connection of the heat dissipation device with the main body of the cutting equipment, but also ensures the stability of the connection. During the cutting process, the equipment will generate vibration and impact force. This stable connection method can prevent the heat dissipation device from being displaced due to vibration, ensuring that the heat dissipation device is always in the correct position and maintains a good relative positional relationship with the guide wheel 3, thereby ensuring the stability and reliability of the heat dissipation effect. At the same time, the clamping of the clamping plate 5010 of the upper cover plate 501 of the wheel body base 5 with the groove of the wheel body base 5, the slot fixing of the cooling pipe fitting 6 in the cavity of the wheel body base 5, and other detailed designs further enhance the connection stability between the components of the entire heat dissipation device, avoiding the influence of component loosening on the heat dissipation function during work.

[0065] It should be understood by those skilled in the art that the embodiments of the utility model shown in the above description and the drawings are only examples and do not limit the utility model. The purpose of the utility model has been completely and effectively realized. The function and structural principle of the utility model have been demonstrated and explained in the embodiments, and the implementation of the utility model can be any deformation or modification without departing from the principle.
