Pipe billet cooling centering machine

Abstract

The invention relates to a pipe billet cooling centering machine and belongs to processing equipment of a pipe billet producing preparation period of seamless steel pipes and is particularly suitable for rolling pipe billets of large-diameter think-wall seamless pipes and pipe billet prepares of alloy steel pipes. The pipe billet cooling centering machine structurally includes that a hydraulic clamp is installed on the front potion of the base seat through a fastening bolt and a location pin, a min machine is fixed on the upper portion of the base seat through the fastening bolt and a location key, a magnetism chip cleaner is placed on the lower portion of the base seat and is used for collecting scrap irons machining down from the pipe billets when the pipe billets in centering, an emulsified liquid cooling system is connected on the back portion of a draw rod on the main machine through a rotating connecter and used for providing cooling liquid for drilling tools, one fixing end of a position detecting device is fixed on the base seat, and one moving end is fixed on a sliding seat of the main machine, the position of a detecting sliding seat is the position of a drill on the main machine, a hydraulic system is used for providing hydraulic oil for a hydraulic clamping cylinder of the hydraulic clamp and driving the hydraulic cylinder to operate, a sweep collecting frame is placed on the lower portion of a chip removal opening of the magnetism chip cleaner. The pipe billet cooling centering machine has the advantages of being novel in structure, easy and convenient to manufacture, convenient to use, capable of reducing energy consumption, accurate in centering, capable of reducing pollutions and the like.

Description

technical field [0001] The tube billet cold centering machine of the present invention belongs to the processing equipment of the tube blank preparation section of seamless steel tube production, and is especially suitable for the tube blank preparation of rolling large-diameter thick-wall seamless tube and alloy steel tube. Background technique [0002] At present, in the seamless pipe industry, most domestic enterprises use thermal centering or non-centering. Uncentering and thermal centering have the following disadvantages and deficiencies: [0003] 1. If the tube blank is not centered, the wall thickness of the front end of the capillary tube will be uneven. [0004] 2. When the alloy steel is perforated, the amount of reduction is small, and the uncentered tube blank will make it difficult to bite in the second time. [0005] 3. Heat centering needs to heat the end of the tube billet and add heating equipment. [0006] 4. Arc gouging is centered, and there is a lot ...
