Description

Technical Field

[0001] This utility model relates to the field of band saw technology, specifically to a water-cooled oil pipe assembly for a band saw. Background Technology

[0002] Band saws are common metal cutting equipment. Their hydraulic station provides power to the entire machine. During operation, the hydraulic oil generates a lot of heat due to frequent compression and valve throttling, causing the oil temperature to rise. Excessively high oil temperature accelerates hydraulic oil oxidation, reduces viscosity, and affects sealing performance. Ultimately, this leads to decreased hydraulic system efficiency, component damage, or even machine shutdown, severely impacting production efficiency and equipment lifespan.

[0003] Currently, the hydraulic power unit of a band saw is typically cooled by a separate oil cooler or air cooler. This cooler requires additional installation space and electrical drive (such as a fan or water pump), which not only increases the manufacturing cost and energy consumption of the equipment but also makes the overall structure more complex. On the other hand, the cutting fluid tank of the band saw is used to store and circulate the cutting fluid. In cold environments, the cutting fluid is at risk of freezing, which may cause damage to the water pump or blockage of the pipeline.

[0004] In existing technologies, cooling of hydraulic systems and antifreeze of cutting fluids are two separate issues requiring two different systems to address, thus failing to achieve efficient use of energy and resources. Therefore, there is an urgent need for an integrated solution that can simultaneously solve both problems, simplify system structure, and reduce energy consumption. Utility Model Content

[0005] The technical problem this invention aims to solve is to address the shortcomings of existing technologies by providing a water-cooled oil pipe assembly for band saws. This assembly utilizes the band saw's built-in cutting fluid tank to cool the hydraulic station, thereby reducing the operating temperature of the hydraulic oil. Simultaneously, when the ambient temperature is low, it can utilize the temperature of the hydraulic oil to exchange heat with the cutting fluid, preventing the cutting fluid from freezing.

[0006] The technical problem to be solved by this utility model is achieved through the following technical solution: a water-cooled oil pipe assembly for a band saw, which is installed between the hydraulic station and the cutting fluid tank of the band saw, and includes a cooling pipe, an oil inlet pipe and an oil outlet pipe.

[0007] The cooling pipe is installed inside the cutting fluid tank of the band saw, and the cooling pipe has an inlet and an outlet, both of which are located outside the cutting fluid tank.

[0008] One end of the oil inlet pipe is connected to the inlet of the cooling pipe, and the other end is connected to the oil pump outlet of the hydraulic station of the band saw.

[0009] One end of the oil outlet pipe is connected to the outlet of the cooling pipe, and the other end is connected to the oil inlet of the valve group of the hydraulic station of the band saw.

[0010] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned water-cooled oil pipe assembly for band saws, wherein the cooling pipe is a cooling coil, which is installed on the bottom inner wall of the cutting fluid tank.

[0011] The technical problem to be solved by this utility model can also be achieved by the following technical solution: the above-mentioned water-cooled oil pipe assembly for band saws has a connecting pipe installed on the oil inlet pipe for connecting to the oil pump outlet of the band saw hydraulic station, and the other end of the connecting pipe is fixedly connected to the oil pump outlet.

[0012] A pressure gauge for detecting hydraulic oil pressure is installed on the outer circumference of the connecting pipe.

[0013] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the water-cooled oil pipe assembly for band saws described above, wherein the oil inlet pipe and the oil outlet pipe are flexible hoses.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are:

[0015] (1) Heat exchange is achieved through the temperature difference between the cutting fluid tank and the hydraulic station. Under normal working conditions, the cutting fluid with a lower temperature is used to cool down the high-temperature hydraulic oil to ensure the stable operation of the hydraulic system. In low-temperature environments, the hydraulic oil with a higher temperature after working is used to heat the cutting fluid to prevent it from freezing, thus realizing the recycling of energy without the need for additional energy consumption.

[0016] (2) This assembly eliminates the traditional independent oil cooler and its matching power components, and directly uses the equipment's inherent cutting fluid tank as the heat exchange medium, which simplifies the overall structure, saves installation space, and reduces manufacturing costs and maintenance complexity.

[0017] (3) By effectively controlling the working temperature of hydraulic oil, the aging of oil is slowed down, and precision components such as hydraulic pumps and valve groups are protected, which significantly improves the reliability and service life of the hydraulic system. At the same time, it avoids the risk of cutting fluid freezing at low temperature and ensures the normal start-up and operation of the cooling system.

[0018] (4) The assembly is mainly composed of cooling coils and connecting hoses. It has extremely low manufacturing and installation costs and can be widely used in the manufacturing of new saws or the upgrading and transformation of existing old equipment. It is highly practical. Attached Figure Description

[0021] The specific technical solutions of this utility model are further described below with reference to the accompanying drawings, so as to enable those skilled in the art to further understand this utility model, without constituting a limitation on its rights.

[0022] Example 1, referring to Figure 1 A water-cooled oil pipe assembly for a band saw is provided, which is located between the hydraulic station 2 and the cutting fluid tank 3 of the band saw 1. The hydraulic station 2 and the cutting fluid tank 3 of the band saw 1 are both existing technologies. The assembly includes a cooling pipe 4, an oil inlet pipe 5 and an oil outlet pipe 6. The oil inlet pipe 5 and the oil outlet pipe 6 are flexible hoses, and their lengths can be selected according to the usage requirements.

[0023] The cooling pipe 4 is installed inside the cutting fluid tank 3 of the band saw 1. The cooling pipe 4 has an inlet 7 and an outlet 8. Both the inlet 7 and the outlet 8 of the cooling pipe 4 are located outside the cutting fluid tank 3. The cooling pipe 4 is a cooling coil, which is installed on the bottom inner wall of the cutting fluid tank 3.

[0024] One end of the oil inlet pipe 5 is connected to the inlet 7 of the cooling pipe 4, and the other end is connected to the oil outlet of the oil pump 9 of the hydraulic station 2 of the band saw 1. After the oil pump 9 outputs oil, it enters the cooling coil through the oil inlet pipe 5 to exchange heat with the room temperature cutting fluid in the cutting fluid tank 3, thereby reducing the working temperature of the hydraulic oil. A connecting pipe 10 is installed on the oil inlet pipe 5 to the oil outlet of the oil pump 9 of the hydraulic station 2 of the band saw 1. The connecting pipe 10 is a straight pipe, and the other end of the connecting pipe 10 is fixedly connected to the oil outlet of the oil pump 9. A pressure gauge for detecting the hydraulic oil pressure is installed on the outer circumference of the connecting pipe 10, and the pressure of the hydraulic oil can be observed through the pressure gauge.

[0025] One end of the oil outlet pipe 6 is connected to the outlet 8 of the cooling pipe 4, and the other end is connected to the oil inlet of the valve group 11 of the hydraulic station 2 of the band saw 1. The cooled hydraulic oil enters the valve group 11 of the hydraulic station 2 through the oil outlet pipe 6 and is used subsequently.

[0026] When using the water-cooled oil pipe assembly for the band saw in Example 1:

[0027] (1) Under normal operating conditions: Due to the frequent operation of the hydraulic station 2 of the band saw 1, the temperature of the hydraulic oil inside it rises. The hydraulic oil is pumped out through the oil pump 9 and enters the oil inlet pipe 5, cooling coil and oil outlet pipe 6, and finally enters the valve group 11 of the hydraulic station 2. The temperature of the hydraulic oil can be reduced by exchanging heat with the cutting fluid tank 3.

[0028] (2) Under low temperature conditions: Due to the low temperature of the working environment, the cutting fluid in the cutting fluid tank 3 may have a certain condensation phenomenon. In the heat exchange process mentioned above, the hydraulic oil can transfer excess heat to the cutting fluid, thereby increasing the temperature of the cutting fluid and preventing condensation. This achieves the recycling of energy without the need for additional energy consumption.
