Description

Technical Field

[0001] The utility model relates to the technical field of round tube processing, in particular to a stainless steel belt unwinding device for round tube processing. Background Art

[0002] Stainless steel round tube is a hollow long round steel, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural parts. In addition, when the bending and torsional strengths are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. Most of the stainless steel round tubes are made of stainless steel strips. When producing round tubes, the stainless steel strips are first pressed with rollers to make the two ends warp. On the basis of the previous step, the stainless steel strips are gradually squeezed to make the two ends of the stainless steel strips curl continuously until the stainless steel strips curl into a shape close to the round tube. Finally, the argon arc welding gun is used to weld the two ends of the stainless steel strips at the joint to make it a round tube.

[0003] When some existing stainless steel strip unwinding devices are in use, the stainless steel strip coil is loaded through a suspension structure. The load on the suspension structure is large and concentrated, which easily affects the stability of the suspension structure, resulting in reduced safety in the use of the device.

[0004] For example, a stainless steel strip coil auxiliary unloading device disclosed in the announcement number CN218642082U can adjust the stainless steel strip coils according to the different diameters of different parent coils when placing the stainless steel strip coils, so that the parent coils are more closely fitted to the placement structure. At the same time, it can also adjust and correct the different thicknesses of the stainless steel strip coils to prevent the stainless steel strip coils from shaking between the two adjustment rollers when unloading.

[0005] This patent installs stainless steel strip coils and mother coils through the placement structure inside the installation frame. The stainless steel strip coils and mother coils are in a suspended state, which will impose a large load on the installation frame, and the load is relatively concentrated, which can easily affect the structural stability of the installation frame and reduce the safety of the device.

[0006] Therefore, it is necessary to invent a stainless steel strip unwinding device for round tube processing to solve the above problems. Utility Model Content
