[0009] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0010] Please refer to Figures 1 to 8 , a welding process comprising the following steps: Step 1: Place the wire drawing composite material 1 in the lower die 4 of the welding die; and set two sets of belts around the outer periphery of the lower die 4; Step 2: Lay the upper structure 11 of the wire drawing composite material 1 on the upper end of the lower mold 4; lay the upper edge of the shroud 2 on the upper structure 11 of the wire drawing composite material 1; Step 3, move the upper mold 3 of the welding mold downward, so that the upper and lower molds 4 are attached to and pressed against the upper structure 11 of the drawing composite material 1 and the upper edge of the shroud 2, so that the upper structure 11 of the drawing composite material 1 and the upper edge of the shroud 2 are pre-connected; Step 4: open the upper and lower molds 4 and flip the wire drawing composite material 1 and the shroud 2 after the first welding, so that the upper structure 11 of the wire drawing composite material 1 faces the lower side of the lower mold 4 and is laid to the upper end of the lower mold 4; re-sleeve the shroud 2 to the outer periphery of the lower mold 4; Step 5: Lay the lower structure 12 of the wire drawing composite material 1 on the upper structure 11 corresponding to the upper end of the lower mold 4; turn up the lower edge of the shroud 2 and lay it on the lower structure 12 of the wire drawing composite material 1; Step 6, move the upper mold 3 downward, so that the upper and lower molds 4 are attached to and pressed against the lower structure 12 of the drawing composite material 1, the lower edge of the shroud 2, the upper structure 11 of the drawing composite material 1 and the upper edge of the shroud 2; Step seven: welding the lower structure 12 of the drawn composite material 1 , the lower edge of the shroud 2 , the upper structure 11 of the drawn composite material 1 and the upper edge of the shroud 2 by welding equipment.

[0011] From the above description, it can be seen that the beneficial effect of the present invention is that: compared with the traditional processing and splicing of the outer strips of the drawn material that requires a viscose process, a hot air rolling process, and a short mold splicing process, the use of the above-mentioned welding process can simplify the production process and achieve rapid welding of the upper and lower layer structures of the drawn composite material 1 and the upper and lower edges of the surrounding belt 2.

[0012] Furthermore, step three also includes the following steps: The pre-connection is performed by welding the upper structure 11 of the wire drawing composite material 1 and the upper edge of the shroud 2 through welding equipment.

[0013] From the above description, it can be seen that the pre-connection is used to connect the upper structure 11 of the drawn composite material 1 and the upper edge of the shroud 2 to avoid disconnection during the subsequent flipping process; the pre-connection of the upper structure 11 of the drawn composite material 1 and the upper edge of the shroud 2 can be achieved by welding with welding equipment.

[0014] Furthermore, step three also includes the following steps: The pre-connection is performed by gluing the upper structure 11 of the wire drawing composite material 1 and the upper edge of the circumference belt 2 through gluing equipment.

[0015] From the above description, it can be seen that the pre-connection is used to connect the upper structure 11 of the drawn composite material 1 and the upper edge of the belt 2 to avoid connection separation during the subsequent flipping process; the pre-connection of the upper structure 11 of the drawn composite material 1 and the upper edge of the belt 2 can be achieved by gluing with gluing equipment.

[0016] Furthermore, step 2 also includes the following steps: The lower structure 12 of the wire drawing composite material 1 is pressed into the lower die 4 .

[0017] From the above description, it can be known that by pressing the lower structure 12 of the drawing composite material 1, it can be separated from the upper structure 11 of the drawing composite material 1, thereby facilitating the laying of the upper structure 11 of the drawing composite material 1 to the upper end of the lower mold 4 and performing subsequent operations.

[0018] Furthermore, the welding equipment is a high-frequency welding equipment.

[0019] It can be seen from the above description that the use of high-frequency welding equipment for welding operations can improve welding quality and save energy consumption, and can be applied to regular and small-thickness rapid welding of the wire drawing composite material 1 and the shroud 2 .

[0020] Furthermore, in the above steps, a robot is used to complete the transfer, laying and flipping operations of the wire drawing composite material 1 and the surrounding belt 2.

[0021] From the above description, it can be seen that the robot arm can realize automated operation and improve production and processing efficiency.

[0022] Furthermore, the welding mold includes an upper mold 3 and a lower mold 4, the lower mold 4 includes a main body 41 and a pressing portion 42, the main body 41 is annular, the inner edge of the main body 41 is adapted to the shape of the drawn inflatable bed to be processed, the upper end of the main body 41 is connected to the pressing portion 42, and the pressing portion 42 protrudes from one side of the outer periphery of the main body 41; the upper mold 3 is pressed against the pressing portion 42.

[0023] From the above description, it can be seen that the above-mentioned welding mold can be used to shape the belt 2 through the outer periphery of the main body 41 of the lower mold 4. The protruding pressing portion 42 can ensure the tight fitting of the belt 2, while also providing a certain operating space to facilitate the folding operation of the belt 2.

[0024] Furthermore, the pressing portions 42 protrude from two sides of the body 41 .

[0025] From the above description, it can be seen that the pressing portion 42 protrudes from both sides of the main body 41 to form a T-shaped structure. Its protrusion on the inner side of the main body 41 can block the lower structure 12 of the drawn composite material 1 when the upper structure 11 of the drawn composite material 1 is laid and welded, thereby preventing it from folding to the pressing portion 42 and affecting the laying and welding operations.

[0026] Furthermore, the end surface area of ​​the pressing portion 42 is larger than the end surface area of ​​the upper mold 3 .

[0027] From the above description, it can be seen that by designing the end surface area of ​​the upper mold 3 and the pressing part 42, it can be ensured that the wire drawing composite material 1 and the surrounding belt 2 can be accurately pressed and fixed when the upper and lower molds 4 are closed, thereby reducing the occurrence of pressing misalignment caused by the offset of the upper and lower molds 4.

[0028] A wire drawing inflatable bed is made by the above-mentioned welding process, and includes a wire drawing composite material 1 and a shroud 2. The shroud 2 is arranged along the circumference of the wire drawing composite material 1, and the upper edge of the shroud 2 is welded to the upper structure 11 of the wire drawing composite material 1, and the lower edge of the shroud 2 is welded to the lower structure 12 of the wire drawing composite material 1.

[0029] It can be seen from the above description that the wire drawing air bed formed by the above welding process can ensure the firmness and reliability of the welding parts, reduce the welding steps and improve the production efficiency.

[0031] Step 4: open the upper and lower molds 4 and flip the wire drawing composite material 1 and the shroud 2 after the first welding, so that the upper structure 11 of the wire drawing composite material 1 faces the lower side of the lower mold 4 and is laid to the upper end of the lower mold 4; re-sleeve the shroud 2 to the outer periphery of the lower mold 4; Step 5: Lay the lower structure 12 of the wire drawing composite material 1 on the upper structure 11 corresponding to the upper end of the lower mold 4; turn up the lower edge of the shroud 2 and lay it on the lower structure 12 of the wire drawing composite material 1; Step 6, move the upper mold 3 downward, so that the upper and lower molds 4 are attached to and pressed against the lower structure 12 of the drawing composite material 1, the lower edge of the shroud 2, the upper structure 11 of the drawing composite material 1 and the upper edge of the shroud 2; Step seven: welding the lower structure 12 of the drawn composite material 1 , the lower edge of the shroud 2 , the upper structure 11 of the drawn composite material 1 and the upper edge of the shroud 2 by welding equipment.
