Description

Technical Field

[0001] The utility model relates to a pressure rod structural component of a parallel seam welding machine, in particular to a pressure rod structural component used for a small tube shell parallel seam welding machine. Background Art

[0002] When using the parallel seam welding process to perform airtight sealing on various metal tube shells, it is necessary to press down the tube shell cover to ensure that the cover and the tube shell fit closely during sealing and welding, and avoid displacement and warping of the cover, which will affect the airtightness of the sealing and welding. Usually, the parallel seam welding machine equipment has a pressure rod to implement the downward pressure on the cover. For larger tube shells, such as tube shells larger than 4mm*4mm, the pressure rod originally configured by the equipment can implement the downward pressure function well, but for small tube shells smaller than 4mm*4mm, the pressure rod structure size is large, blocking the normal movement of the electrode, and it is impossible to weld the small tube shell. Since the components of the pressure rod that meets the pressure of the small tube shell are very small in size and difficult to process, and the components need to be reasonably assembled to achieve the purpose of pressing the sealing cover down and closely contacting the tube shell, the original accessories of the equipment currently do not have a smaller pressure rod to meet the use requirements, and a new pressure rod needs to be designed by yourself to meet the airtight sealing requirements of the small tube shell.

[0005] Furthermore, the contact protection member has a cylindrical shape with a diameter of 1.0 mm and a height of 2 mm. A blind hole is opened on the upper surface of the cylindrical plane with a diameter of 0.7 mm and a height of 1.3 mm.
