Speed reduction device of pipe mill transmission box

Abstract

The invention discloses a speed reduction device of a pipe mill transmission box. The speed reduction device comprises the transmission box, a gearbox, a motor and a brake, wherein one end of the gear box is fixedly connected with a transmission shaft of the transmission box, the other end of the gearbox is fixedly connected with an output shaft of the motor through a belt, one end of the output shaft of the motor is connected with a pipe sleeve, the pipe sleeve is located in a fixture of the brake, and one end of the brake is fixedly connected with a brake electromagnet. The speed reduction box has the advantages that the transmission speed can be stable and uniform, the speed reduction box can be immediately stopped when breaking down, it is ensured that the rolling effect of stainless steel pipes is good, and the rolling is uniform.

Description

technical field [0001] The invention relates to a deceleration device for a transfer box of a pipe rolling mill. Background technique [0002] When processing stainless steel pipes, they are generally rolled by a pipe rolling machine, because the stainless steel pipes drawn by the pipe rolling machine have a high yield and precision surface roughness is better than that of cold drawn pipes. [0003] At present, the stainless steel pipe that needs to be cold-rolled is sent to the transfer box of the pipe rolling machine, and the mandrel is docked and sent to the machine through the transfer device for cold rolling. If the transfer speed is too fast, it will cause the cold-rolled effect of the stainless steel pipe. Poor and uneven. When a problem is found during the working process, the transmission box needs to be stopped immediately, waiting for the staff to repair it. However, due to inertia and other factors, the transmission rod cannot stop immediately. If the maintena...

[0003] At present, the stainless steel pipe that needs to be cold-rolled is sent to the transfer box of the pipe rolling machine, and the mandrel is docked and sent to the machine through the transfer device for cold rolling. If the transfer speed is too fast, it will cause the cold-rolled effect of the stainless steel pipe. Poor and uneven. When a problem is found in the working process, the transmission box needs to be stopped immediately, and the staff needs to repair it. However, due to factors such as inertia, the transmission rod cannot be stopped immediately. If the maintenance is not timely, it will lead to serious consequences.
