Novel mechanical locking drill rod three-part guide plate and production method thereof

Abstract

The invention provides a novel mechanical locking drill rod three-part guide plate and a production method thereof. The guide plate is characterized by being formed through welding N splicing blocks, wherein N is not smaller than 2; a gutter channel of 40-50 mm is formed in the middle part of the guide plate; and the splicing blocks use steel plate materials. The guide plate uses steel plates as materials, so that the flame retardance, the high-temperature stability and the bearing capacity of the guide plate are enhanced, the guide plate cannot generate the burning phenomenon under general conditions, and the guide plate can be effectively used for a long time under various severe environments to guarantee the operation of a drill rod. The guide plate consists of N splicing blocks, and welding spots are arranged in the connecting places, so that the extension function of the guide plate can be effectively improved in use; and the gutter channel is formed in the middle of the guide plate, so that the extension function of the guide plate also can be strengthened, the rupture condition of the guide plate due to excessive stretching in use is prevented, and the service life of the guide plate is prolonged imperceptibly.

Description

technical field [0001] The invention relates to the field of manufacturing drill pipe parts, in particular to a novel machine-locked drill pipe three-lobe guide plate and a manufacturing method thereof. Background technique [0002] The guide plate, also called the support ring, is a part used on the piston or piston rod of the hydraulic cylinder or cylinder to support the movement of the piston or piston rod. It can prevent the piston or piston rod from directly contacting the cylinder during the movement. Contact and friction play a role in protecting the cylinder and piston or piston rod from being damaged. The high-temperature bearing capacity of today's guide plates is poor, and crushing often occurs during use. In the past, the guide plates were welded with the entire ring on the pipe, and deformation and falling off occurred. Today's guide plate processing process is generally: forging (ring) - machining - quenching and tempering - welding, the processing process is ...
