Embodiment Construction

[0012] see figure 1 and figure 2 , the present invention relates to a rounding machine for drill pipe thread protection sleeve, comprising a base 1, a motor 2 is fixed on one side of the top of the base 1, the motor 2 is connected with a pulley 4 through a belt 3, and the pulley 4 is connected with the two rollers 5 through the reduction box, so as to drive the two rollers 5 to rotate in the same direction. A baffle I7 is vertically arranged on the rear side of the rear roller 5, and a baffle II8 is arranged transversely between the two rollers 5.

[0013] The rolling machine of this kind of drill pipe thread protection sleeve first puts the flat plate under the previous roller 5, and the flat plate is swept away by the roller 5 and then blocked by the baffle Ⅰ7, so that it can be rolled up with the rotation of the roller 5. One end of the flat plate touches the baffle Ⅱ 8 arranged horizontally between the two rollers 5 and stops rolling. After the operator takes it out, it...

Abstract

The invention relates to a rounding machine for drill pipe thread protection sleeve, which is characterized in that it comprises a machine base (1), and a motor (2) is fixed on one side of the top of the machine base (1), and the motor (2) ) is connected to the pulley (4) through the belt (3), and the pulley (4) is connected to the two rollers (5) through the reduction box, and the two rollers (5) are set on the On the base (1), a baffle plate I (7) is vertically arranged on the rear side of the rear roller (5) of the two rollers (5), and the horizontal direction between the two rollers (5) A baffle II (8) is provided. The rounding machine of the drill pipe thread protection sleeve of the present invention can make the flat plate follow the rotation of the roller to roll round. When one end of the flat plate touches the baffle plate II arranged horizontally between the two rollers, the rounding will stop, and the operator will After it is taken out, it can be directly welded to form a thread protection sleeve, which is not only convenient to operate, but also improves work efficiency.

Description

technical field [0001] The invention relates to a rolling machine for a drill pipe thread protection sleeve, which is used for rolling the thread protection sleeve from a flat plate into a cylindrical sheath. Background technique [0002] Drill pipe is used in drilling for oil, gas, water and mineral deposits. Although the structure of the drill pipe is simple, its quality requirements are relatively high. Usually, the drill pipes are easily worn during transportation, which leads to the failure of the normal connection between the drill pipes, and even causes safety accidents. Therefore, it is necessary to set a thread protector at the drill pipe joint to prevent the drill pipe joint from wearing and tearing. [0003] The threaded protective sleeve is a flat plate before being rolled into a cylindrical sheath, which needs to be put into a mold to make a shape. However, the production through the mold is not only slow, but also inconvenient to operate and low in efficiency...
