Description

Technical Field

[0001] This utility model relates to precision manufacturing technology and its equipment, specifically, an ultra-thin stainless steel strip welding platform that integrates cooling and gas protection. Background Technology

[0002] With the rapid development of industries such as precision manufacturing, new energy batteries, and medical devices, the market has put forward an urgent demand for the welding quality of ultra-thin stainless steel strip components, which requires "high strength, high sealing performance, and high aesthetics".

[0003] In the laser welding process of ultra-thin stainless steel strips, effectively controlling heat input and preventing oxidation on the back side of the weld are two major technical challenges.

[0004] In existing technologies, heat dissipation usually relies on natural cooling or simple air cooling, which is inefficient; the back protection often uses simple gas nozzles, resulting in uneven protection.

[0005] These shortcomings lead to low welding yield and unstable weld quality. Therefore, there is an urgent need for a dedicated welding platform that can integrate efficient heat dissipation and uniform gas protection.

[0006] Therefore, it is necessary to provide an ultra-thin stainless steel strip welding platform that integrates cooling and gas protection to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide an ultra-thin stainless steel strip welding platform that integrates cooling and gas protection, effectively solving the problems of heat dissipation and back-side oxidation during the welding process.

[0008] The technical solution is as follows: An integrated cooling and gas protection ultra-thin stainless steel strip welding platform includes a platform body with corresponding gaps for welding seams, which serves as a support for the ultra-thin stainless steel strip to be welded. The platform body is equipped with a circulating water-cooling module, forming a high-efficiency thermally conductive and cooling ultra-thin stainless steel strip support platform structure. A back gas protection module is provided on the gap corresponding to the weld seam. The back gas protection module is used as a protective gas supply part at the weld seam, forming a gas-protected ultra-thin stainless steel strip support platform structure at the weld seam. The combination of a high-efficiency thermally conductive cooling ultra-thin stainless steel strip support platform structure and a gas-protected ultra-thin stainless steel strip support platform structure at the weld seam forms an integrated ultra-thin stainless steel strip welding platform structure that integrates cooling and gas protection.

[0009] Furthermore, the platform body is made of a high thermal conductivity copper alloy.

[0010] Furthermore, the circulating water-cooling module includes a mesh-like circulating water-cooling channel that extends deep into the platform body to quickly dissipate the heat generated during welding.

[0011] Furthermore, the back gas protection module includes a gas chamber installed inside the platform body. The gas chamber is connected to an external protective gas source. Several tiny gas grooves and protective gas nozzles are provided above the gas chamber. The tiny gas grooves and protective gas nozzles are evenly distributed on the corresponding gaps of the weld seam, and are used as an actuator to uniformly deliver high-purity inert gas to the back of the weld seam to form a continuous protective layer.

[0012] Furthermore, the protective gas is argon.

[0013] Furthermore, the platform itself is also equipped with an adsorption module.

[0014] Furthermore, the adsorption module includes several vacuum adsorption ports installed on the platform body, and the vacuum adsorption ports are connected to an external vacuum adsorption pressure supply device through vacuum adsorption pipes.

[0015] Compared with existing technologies, this invention is made of a high thermal conductivity copper alloy; the internal circulating water-cooling channel is connected to an external water chiller to form a closed loop; the gas chamber is connected to a high-purity argon gas source through a pipe; when the tooling fixture is pressed onto the platform body, the platform's finely ground vacuum adsorption port ensures adsorption force on the smooth thin steel strip, and the airflow generated by the incomplete sealing of the hard seal plays an auxiliary role in heat dissipation of the steel strip. During welding, argon gas is evenly sprayed from the nozzles connected by tiny gas grooves, covering the back of the weld. The argon gas injection at a certain pressure produces a heat absorption effect due to expansion, while the water-cooling channel continuously removes heat from the welding platform, achieving dual protection for the welding process.

[0020] Example:

[0021] Please see Figure 1-4 This embodiment demonstrates an ultra-thin stainless steel strip welding platform integrating cooling and gas protection, including a platform body 100, on which a weld seam corresponding gap 200 is provided to serve as a support for the ultra-thin stainless steel strip to be welded. The platform body 100 is equipped with a circulating water cooling module 1, forming a high-efficiency heat-conducting and cooling ultra-thin stainless steel strip support platform structure. A back gas protection module 2 is provided on the gap 200 corresponding to the weld seam. The back gas protection module 2 is used as a protective gas supply part at the weld seam, forming a gas protection type ultra-thin stainless steel strip support platform structure at the weld seam. The combination of a high-efficiency thermally conductive cooling ultra-thin stainless steel strip support platform structure and a gas-protected ultra-thin stainless steel strip support platform structure at the weld seam forms an integrated ultra-thin stainless steel strip welding platform structure that integrates cooling and gas protection.

[0022] The platform body 100 is made of a high thermal conductivity copper alloy.

[0023] The circulating water cooling module 1 includes a mesh-like circulating water cooling channel 11 that extends deep into the platform body 100 to quickly conduct away the heat generated during welding.

[0024] The back gas protection module 2 includes a gas chamber 21 disposed in the platform body 100. The gas chamber 21 is connected to an external protective gas source. Several micro gas grooves and protective gas nozzles 22 are disposed above the gas chamber 21. The micro gas grooves and protective gas nozzles 22 are evenly distributed on the corresponding gaps 200 of the weld seam, and are used as an actuator to uniformly deliver high-purity inert gas to the back of the weld seam to form a continuous protective layer.

[0025] The protective gas is argon.

[0026] The platform body 100 is also equipped with an adsorption module 3.

[0027] The adsorption module 3 includes several vacuum adsorption ports 31 set on the platform body. The vacuum adsorption ports 31 are connected to an external vacuum adsorption pressure supply device through a vacuum adsorption tube 32.

[0028] Compared with existing technologies, this invention is made of a high thermal conductivity copper alloy; the internal circulating water-cooling channel is connected to an external water chiller to form a closed loop; the gas chamber is connected to a high-purity argon gas source through a pipe; when the tooling fixture is pressed onto the platform body, the platform's finely ground vacuum adsorption port ensures adsorption force on the smooth thin steel strip, and the airflow generated by the incomplete sealing of the hard seal plays an auxiliary role in heat dissipation of the steel strip. During welding, argon gas is evenly sprayed from the nozzles connected by tiny gas grooves, covering the back of the weld. The argon gas injection at a certain pressure produces a heat absorption effect due to expansion, while the water-cooling channel continuously removes heat from the welding platform, achieving dual protection for the welding process.
