Description

Technical Field

[0001] This utility model belongs to the field of pipeline welding technology, specifically a workpiece cooling and clamping device. Background Technology

[0002] The copper-steel muffler for air conditioning is a noise reduction device designed specifically for air conditioning systems, combining the properties of copper and steel. It achieves efficient noise control through optimized structure and material combination. Utilizing the high thermal conductivity and ductility of copper, a microporous structure or resonant cavity is formed on the inner wall of the muffler. High-frequency noise is reduced through sound wave friction and heat dissipation. The steel layer uses high-strength steel to construct the outer shell and support structure. Its elastic modulus can suppress the transmission of low-frequency vibrations, while its corrosion resistance extends the equipment's lifespan.

[0003] The welding technology of copper-steel mufflers for air conditioners is a key process to ensure the high strength, high sealing and durability of copper-steel composite structures. Since the coefficient of thermal expansion of copper is 1.4 times that of steel, the expansion of the copper side is significantly greater than that of the steel side during welding. Therefore, if the temperature is not cooled down in time during welding, cracks are likely to appear in the weld area, affecting the normal use of the air conditioner.

[0004] In summary, this utility model provides a workpiece cooling and clamping device to solve the above problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0025] Example 1

[0026] like Figure 1-4 As shown, this is the first embodiment of the present invention, which provides a workpiece cooling and clamping device, including,

[0027] The fixing unit 100 includes a fixing collar 104, which is used to fix the copper steel muffler.

[0028] The fixing collar 104 also includes a shrinkage groove 1041 formed on its inner surface, a spring 1042 fixedly connected to the inner wall of the shrinkage groove 1041, and a protrusion 1043 fixedly connected to one end of the spring 1042 and movably connected to the surface of the fixing collar 104.

[0029] The cooling mechanism 200 includes a collar 201 fixedly connected to the top of the fixed collar 104, a nozzle 202 disposed in the inner cavity of the collar 201, a hose 203 connected to one end of the collar 201, and a submersible pump 204 connected to the hose 203 for water supply.

[0030] like Figure 1-4 As shown, before welding, the lower end of the copper-steel muffler, namely the steel resonant cavity, is first inserted into the collar 201 and then into the fixing collar 104. The fixing collar 104 achieves self-adaptive clamping of the copper-steel muffler through the synergistic action of the contraction groove 1041, the spring 1042, and the protrusion 1043, which can ensure the stability of the muffler during welding. At the same time, during welding, the cooling mechanism 200 sprays cooling water into the steel resonant cavity of the muffler inserted into the collar 201 through the nozzle 202 to achieve rapid cooling during welding.

[0031] The hose 203 and the submersible pump 204 ensure the continuous supply and circulation of cooling water. The submersible pump 204 delivers the cooling water in the water tank 101 to the nozzle 202 through the hose 203 to form a circulation system.

[0032] Example 2

[0033] Reference Figure 2 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] In this embodiment, the fixing unit 100 also includes a water tank 101 for holding water, a triangular truncated surface 102 disposed in the inner cavity of the water tank 101, and a support rod 103 fixedly connected between the water tank 101 and the triangular truncated surface 102. The triangular truncated surface 102 is fixedly connected to the fixing collar 104.

[0035] The top of the triangular platform 102 has a hole that communicates with the fixing collar 104 for the insertion of the copper steel muffler.

[0036] The inner diameter of the collar 201 is larger than the inner diameter of the fixed collar 104. The inner diameter of the fixed collar 104 is smaller to facilitate fixing the copper-steel muffler, while the inner diameter of the collar 201 is larger to increase the space between it and the copper-steel muffler.

[0037] like Figure 2 As shown, the water tank 101 serves as a cooling medium container, and the triangular platform 102 and support rod 103 fix the position of the muffler. The bottom of the steel resonant cavity of the muffler passes through the hole at the top of the triangular platform 102 and is directly immersed in the cooling water in the inner cavity of the water tank 101, thereby accelerating heat dissipation and quickly removing welding heat. The inner diameter of the collar 201 is larger than that of the fixing collar 104, providing a larger spray space for the nozzle 202 and ensuring that the cooling water can cover a wider area. The nozzle 202 sprays the cooling water directly to the position below the weld area, thereby rapidly reducing the temperature of the steel resonant cavity of the muffler and reducing hot cracking and deformation.

[0038] Example 3

[0039] Reference Figure 1 and Figure 3 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0040] In this embodiment, the mounting base of the submersible pump 204 is fixed to the inner cavity of the water tank 101 by bolts.

[0041] A drain pipe is connected to one side of the water tank 101, and a valve is provided on the surface of the drain pipe. The water filling depth of the water tank 101 does not exceed the top of the fixing collar 104.

[0042] Limiting grooves 1041a are provided on both sides of the inner cavity of the shrinkage groove 1041. Limiting sliders 1041b are slidably connected to the inner cavity of the limiting grooves 1041a. The end of the limiting slider 1041b away from the limiting grooves 1041a is fixedly connected to the protrusion 1043.

[0043] like Figure 1 and Figure 3 As shown, the mounting base is fixed to the inner cavity of the water tank 101 by bolts, which reduces the vibration and noise of the submersible pump 204 during operation, facilitates the disassembly and maintenance of the submersible pump 204, and reduces maintenance costs. The drain pipe and valve are used to control the water level and drainage in the water tank 101. The water filling depth in the water tank 101 does not exceed the top of the fixing collar 104, which is intended to control the cooling water from submerging the collar 201 and prevent the welding area from being flooded. The limiting slide groove 1041a and the limiting slider 1041b constrain the movement trajectory of the protrusion 1043, ensure the stability and uniformity of the clamping force, and make the protrusion 1043 slide stably in the contraction groove 1041.

[0044] During use, before welding, the lower end of the copper-steel muffler, i.e., the steel resonant cavity, is first inserted into the collar 201, and then the fixing collar 104 is inserted. The fixing collar 104 achieves self-adaptive clamping of the copper-steel muffler through the coordinated action of the contraction groove 1041, the spring 1042, and the protrusion 1043. When the steel resonant cavity of the muffler is inserted, it squeezes the protrusion 1043, and the force it exerts squeezes the spring 1042. The restoring force of the spring 1042 continuously applies force to the steel resonant cavity of the muffler, and is clamped and fixed by the protrusion 1043. This ensures noise reduction during welding. To ensure the stability of the device, during welding, the submersible pump 204 delivers cooling water from the water tank 101 to the nozzle 202 via the hose 203. The nozzle 202 sprays cooling water onto the steel resonant cavity of the muffler inserted into the inner cavity of the collar 201, achieving rapid cooling during welding. The inner diameter of the collar 201 is larger than that of the fixed collar 104, providing a larger spray space for the nozzle 202 and ensuring that the cooling water can cover a wider area. The nozzle 202 sprays the cooling water directly to a position below the weld area, thereby rapidly reducing the temperature of the steel resonant cavity of the muffler and reducing hot cracking and deformation.

The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.

[0046] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
