Abstract

The invention discloses a drawing driving mechanism in a seamless steel pipe drawing machine. According to the technical scheme, the drawing driving mechanism in the seamless steel pipe drawing machine is characterized by comprising a vehicle body arranged on the drawing machine and driven through a chain, wherein the vehicle body is slidably connected to the drawing machine in the length direction of a seamless steel pipe, and the vehicle body is provided with a clamping mechanism used for clamping the end surface of the seamless steel pipe, two connecting mechanisms used for being kept connected with the chain, and a disassembling and assembling mechanism used for disassembling and assembling the clamping mechanism. According to the drawing driving mechanism in the seamless steel pipe drawing machine, the end part of the seamless steel pipe can be ensured to be clamped and fixed, the seamless steel pipe can be driven to synchronously move, and meanwhile, clamping blocks can be disassembled and replaced.

Description

technical field

[0001] The invention relates to a cold drawing machine, in particular to a drawing driving mechanism in a seamless steel pipe drawing machine. Background technique

[0002] Existing seamless steel pipes generally need to be processed into high-precision steel pipes by cold drawing machines. That is, the seamless steel pipe is drawn by a cold drawing machine, so that the seamless steel pipe passes through the inner mold and the outer mold in the cold drawing machine to achieve a finished seamless steel pipe.

[0003] When the existing seamless steel pipe is drawn, the air pressure drives the jaws to move toward each other so that the jaws clamp the seamless steel pipe and drive the seamless steel pipe to move relative to the inner mold and the outer mold.

[0004] But only by air pressure to make the jaws clamp the seamless steel pipe, due to the large force when the seamless steel pipe is drawn, it is easy to cause the seamless steel pipe to break away from ...
