Description

TECHNICAL FIELD

[0001] The utility model relates to composite board welding technical field field, specifically a kind of auxiliary device for composite board weld cooling. BACKGROUND

[0002] In the welding process of explosive composite board, in order to ensure the overall quality of composite board, high-precision welding is usually needed for the weld area of composite board. In the prior art, manual or mechanical welding method is usually used for operation. In the welding process, in order to prevent oxidation or other quality problems in the weld area, a welding gun is usually used to spray protective gas (such as inert gas) to protect the weld area. At the same time, in order to slow down the influence of welding heat accumulation on the weld quality, simple cooling measures such as intermittent welding or external water spraying cooling for the weld area are also taken. These technical solutions can achieve the welding requirement to some extent, but there are still great limitations in actual application.

[0003] The current welding method has limited effect on heat control in the weld area, especially when welding thin plates, the weld heat is easily concentrated, resulting in large thermal deformation in the welding area, thereby affecting the fitting precision and overall quality of the explosive composite board. In addition, the existing protective gas utilization method usually only protects the front of the weld, and the back of the weld is often prone to oxidation or defects due to lack of effective protection measures, thereby reducing the welding quality. In order to achieve higher quality welding, the welding process requires a large amount of protective gas, which significantly increases the material cost and production cost. SUMMARY

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0022] like Figs. 1-3 As shown, an auxiliary device for cooling a composite plate weld provided by an embodiment of the present invention includes a support base plate 1, a welding platform 2 provided on the surface of the support base plate 1, and a groove 3 formed on the surface of the welding platform 2. A cooling water pipe 4 is provided inside the groove 3. The cooling water pipe 4 is arranged inside the groove 3 and is lower than the surface of the groove 3 and does not protrude from the groove 3. The cooling water pipe 4 is made of copper or stainless steel.

[0023] Both ends of the cooling water pipe 4 are connected to a water injection pipe 10 and a water recovery pipe 5 respectively.

[0024] A water tank 9 is provided on the surface of the supporting base plate 1 , and low-temperature cooling water is stored in the water tank 9 .

[0025] The surface of the water tank 9 is connected to the water pump mounting base 8, and the surface of the water pump mounting base 8 is mounted with the water pump 6. The outside of the water pump 6 is connected to the water pump pipe 11. The surface of the water pump 6 is provided with a water inlet interface and a water outlet interface. The end of the water injection pipe 10 away from the cooling water pipe 4 is connected to the water outlet interface, and the water pump pipe 11 is connected to the water inlet interface. The end of the water pump pipe 11 away from the water pump 6 is arranged at the inner bottom of the water tank 9.

[0026] In one embodiment of the present invention, to ensure the stability and efficient thermal conductivity of the cooling water pipe 4 within the groove 3, the cooling water pipe 4 is stably installed within the groove 3 to prevent vibration or displacement caused by water flow or welding. Furthermore, a high-temperature resistant thermally conductive coating can be applied to the outer wall of the cooling water pipe 4 to further enhance the cooling effect and reduce the impact of welding heat on the copper or stainless steel pipe.

[0027] To prevent the cooling effect of the water pump 6 from being reduced due to overload or increased water flow resistance during long-term operation, a filter can be installed at the water inlet interface of the water pump 6 to prevent impurities in the water from entering the pipeline, thereby extending the service life of the water pump. At the same time, a flow control valve is installed at the connection between the water outlet interface of the water pump 6 and the water injection pipe 10 to adjust the flow rate and pressure of the cooling water to adapt to the heat dissipation efficiency under different welding requirements.

[0028] The inside of the water storage tank 9 can be provided with a temperature sensor for real-time monitoring of the temperature of the cooling water. When the temperature exceeds the preset value, an alarm is triggered or an external cooling device (such as a cooler) is started to cool the cooling water in the water storage tank, ensuring that the system always maintains high cooling performance during high-intensity welding operations. An overflow port can also be added to the top of the water storage tank 9 to prevent the water level from rising too high and overflowing due to excessive backflow of cooling water.

[0029] To further improve cooling efficiency, a heat exchange device can be added to the backwater path of the water storage tank 9 and the cooling water pipe 4. By exchanging heat between the backwater and the low-temperature water in the cooling system, the backwater temperature is reduced in advance, thereby reducing the heat dissipation burden of the water storage tank 9 and improving the overall efficiency of the cooling cycle.

[0030] When the water suction pipe 11 is deep into the bottom of the water storage tank 9, a deposition prevention structure such as a conical guide base can be added to prevent impurities deposited at the bottom of the water storage tank from directly entering the water suction pipe 11, affecting the normal operation of the water pump 6. A one-way valve can also be installed at the end of the water suction pipe 11 to prevent backflow of cooling water in the pipe when the water pump stops running, ensuring the stability of the cooling water flow in the system.

[0031] The specific working process of the device is as follows: Place the two composite plates to be welded on the welding platform 2, ensuring that the weld area of the two composite plates is directly above the groove 3 during placement. After connecting the water pump 6, the water pump 6 draws the low-temperature cooling water in the water storage tank 9 into the water injection pipe 10 through the water suction pipe 11 and delivers it to the inside of the cooling water pipe 4. The cooling water rapidly absorbs the heat radiated from the weld area while flowing in the cooling water pipe 4, and sends the high-temperature cooling water back to the water storage tank 9 through the recovery water pipe 5, realizing the recycling of the cooling water. The cooling water pipe 4 is made of high-thermal-conductivity material, which can quickly conduct the welding heat to the circulating cooling water, effectively reducing the temperature of the weld area and avoiding the accumulation of welding heat, which can cause deformation of the composite plate, thereby ensuring the welding quality.

[0032] During welding, to prevent oxidation of the weld, the welding torch sprays protective gas (such as inert gas) onto the weld area. The protective gas enters the inside of the groove 3 through the gap of the weld, forming a protective gas flow environment in the groove 3, which protects the back of the composite plate weld. This design not only improves the utilization efficiency of the protective gas and reduces the waste of inert gas, but also avoids oxidation or other defects on the back of the weld due to lack of protection, further improving the welding quality.

[0033] By the above technical scheme, the device realizes rapid cooling and double-sided protection during welding, effectively avoids thermal deformation of the weld area, improves the utilization rate of protective gas, reduces the cost of welding materials, and significantly improves the welding quality and efficiency. The circulating system of the cooling water is designed reasonably and can operate stably for a long time. The overall structure of the device is simple and convenient to use, and is suitable for welding requirements of composite plates of different sizes, and has strong practicality and economic benefits.

[0034] In this embodiment, the inner bottom of the groove 3 is provided with a plurality of positioning slots 13, and the surface of the cooling water pipe 4 is provided with a plurality of positioning blocks 12. The cross sections of the positioning blocks 12 and the positioning slots 13 are the same, and the cooling water pipe 4 is stably installed in the groove 3 in a suspended manner by cooperating with the positioning blocks 12 and the positioning slots 13.

[0035] This design can stably install the cooling water pipe 4 in the groove 3 in a suspended manner by setting a plurality of positioning slots 13 on the inner bottom of the groove 3 and a plurality of positioning blocks 12 on the surface of the cooling water pipe 4, and cooperating the positioning blocks 12 with the positioning slots 13. The cross sections of the positioning blocks 12 and the positioning slots 13 are the same, and this matching structure can ensure that the cooling water pipe 4 has good stability when installed in the groove 3, and will not be offset or loose due to the impact of water flow or external force.

[0036] The suspended installation mode can effectively avoid the direct contact of the cooling water pipe 4 with the bottom of the groove 3, reduce the heat conduction loss to the groove 3, and thus ensure that the cooling water pipe 4 efficiently conducts the welding heat to the flowing cooling water. In addition, the suspended design can also prevent the impurities that may accumulate at the bottom of the groove or the particles in the cooling water from affecting the performance of the cooling water pipe 4, further improving the heat dissipation effect and service life of the cooling water pipe 4.

[0037] This matching structure design is simple and reliable, facilitating the installation and removal of the cooling water pipe 4, and facilitating subsequent maintenance and cleaning operations, while avoiding the influence of complex fixing parts on the overall structure of the device. Through this design, the running efficiency of the entire cooling system and the reliability of the device are improved.

[0038] In this embodiment, the side of the water storage tank 9 is provided with an external water pipe 7, and the outer side of the external water pipe 7 is provided with a valve.

[0039] The setting of the external water pipe 7 enables the water storage tank 9 to be conveniently connected with an external water source or other water storage equipment, realizing the replenishment or replacement of cooling water. Through the control of the valve, the water flow and water inlet time can be accurately adjusted, ensuring that the water level in the water storage tank 9 is always appropriate during the operation of the cooling system, avoiding the influence of insufficient cooling water on the normal operation of the system.

[0040] The valve can also play a safety control role, for example, when a water supplement source is not needed, the valve can be closed to prevent external water flow from accidentally entering the water storage tank 9, thereby avoiding overflow caused by excessive water in the water storage tank.

[0041] In addition, the design of the external water pipe 7 also makes the system have certain expandability, for example, it can be connected to a circulating cooling system or a refrigeration device to further reduce the temperature of the cooling water and improve the efficiency and adaptability of the entire cooling system. This design is simple in structure, flexible to use, and effectively improves the functionality and operation convenience of the device.

[0042] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
