Technical Field

[0001] The utility model relates to the technical field of transfer devices, in particular to a cold-rolled seamless steel pipe transfer device for automobile transmission shafts. Background Art

[0002] In the application of automobile transmission shafts, the requirements for seamless steel pipes are very high, because the transmission shaft needs to withstand high torque, high-speed rotation and periodic load changes, and at the same time requires good fatigue strength, toughness and rigidity. Due to its superior inherent quality, cold-rolled seamless steel pipes can meet the strict requirements of automobile transmission shafts on material strength, concentricity and straightness, thereby ensuring the stability and reliability of the transmission shaft under long-term and harsh working conditions.

[0003] In the factory, when pipe processing needs to be transferred, a cart is commonly used. For example, the Chinese patent with authorization announcement number CN216508504 U discloses a transfer device for seamless steel pipe production. In this patent, the pipe is fixed by a fixing mechanism, which is OK for shorter pipes, but when transporting longer pipes, the whole will be very unstable, and the pipe is easy to fall, and even cause rollover. For this reason, we propose a cold-rolled seamless steel pipe transfer device for automobile drive shafts. Utility Model Content
