Description

Technical Field

[0001] The utility model relates to the technical field of cold-rolled steel pipes, in particular to a clamping device for a trolley used for cold-rolled steel pipes. Background Technique

[0002] Cold rolling: Using hot-rolled steel coils as raw materials, after pickling to remove the oxide scale, cold tandem rolling is carried out. The finished product is cold-rolled hard coils. Due to the work hardening caused by continuous cold deformation, the strength and hardness of the cold-rolled hard coils increase, and the toughness and plasticity indexes decrease. Therefore, the stamping performance will deteriorate and it can only be used for parts with simple deformation. Cold-rolled hard coils can be used as raw materials for hot-dip galvanizing plants because annealing lines are provided in all hot-dip galvanizing units. Cold-rolled precision seamless steel pipes are seamless steel pipes with high dimensional accuracy and good surface finish for precision mechanical structures, hydraulic equipment or steel bar sleeves. The main cold working methods of steel pipes are cold drawing and cold rolling methods. When cold-rolling steel pipes, a moving trolley is needed to clamp and fix one end of the steel pipe and feed the steel pipe.

[0003] Among them, the "cold rolling mill for seamless steel pipe production and processing" disclosed in the application number "202121800393.6" "comprises a cold rolling mill main body and an installation component. A feeding frame is arranged at the upper end of the cold rolling mill main body. Feeding holes are formed on the surface of the feeding frame. Clamping components are arranged on both sides of the feeding frame, which is convenient for limiting the cold-rolled steel pipe inside the feeding hole, so that the cold-rolled steel pipe can be fixed in the middle position of the feeding hole, which is convenient for processing the cold-rolled steel pipe. Installation rings are detachably installed at both ends of the feeding hole through the installation component. One side of the installation ring is fixedly installed with an installation sleeve inserted into the inner wall of the feeding hole. Cleaning components are fixedly installed on both sides of the inner wall of the installation sleeve, which is convenient for cleaning the dust on the surface of the cold-rolled steel pipe to avoid affecting the later processing of the cold-rolled steel pipe". In the utility model, through the setting of the clamping component, the overall device has a good clamping effect. The user inserts the steel pipe into the feeding hole of the feeding frame. The user rotates the rotating rod, and the rotating rod drives the rotating sleeve to rotate through the transmission sprocket and the transmission chain. The clamping screw rod inside the rotating sleeve moves downward under the action of the connecting block and the connecting groove, so that the arc-shaped clamping plates move in opposite directions inside the feeding hole, which is convenient for limiting steel pipes with different diameters, so that the cold-rolled steel pipe can be fixed in the middle position of the feeding hole, which is convenient for processing the cold-rolled steel pipe.

[0004] However, the above method still has the following defects: By inserting the steel pipe into the feeding hole of the feeding frame and cooperating with the clamping component to fix it, but when installing the steel pipe, the staff needs to align one end of the steel pipe with the feeding hole.
