A seamless steel pipe cold drawn internal mold adjustment and positioning device

Abstract

The invention belongs to the technical field of positioning devices, and discloses a seamless steel pipe cold-drawn internal mold adjustment and positioning device, including a base, a control switch is installed at the middle position of the front surface wall of the base, and the middle position of the upper surface wall of the base is An electric telescopic rod is symmetrically installed at the top of the electric telescopic rod. A fixed block is fixed on the top of the electric telescopic rod. The upper surface wall of the fixed block is provided with a placement groove. The inside of the groove is slidably connected with a slider, and the top of the slider is fixed with a movable plate. Through the cooperation of the screw, splint and bearing in the present invention, when the seamless steel pipe is positioned through the second positioning hole, it can be rotated The screw is used to freely adjust the position of the splint, so that the splint is close to the seamless steel pipe for positioning and fixing. It is suitable for the positioning and fixing of seamless steel pipes of various specifications, which increases the scope of application and is not easy to be eliminated.

Description

technical field [0001] The invention belongs to the technical field of positioning devices, and in particular relates to a positioning device for adjusting and positioning a cold-drawn inner mold of a seamless steel pipe. Background technique [0002] Cold drawing is a processing technology of materials. For metal materials, cold drawing refers to drawing under the condition that the material is at room temperature in order to achieve a certain shape and certain mechanical properties. Forming has the advantages of high dimensional accuracy and good surface finish. When the seamless steel pipe is cold-drawn, it is necessary to use the adjustment and positioning device to fix it to ensure the quality of cold-drawing. [0003] In the Chinese patent with the patent number CN201120487699.0, a cold-drawing internal mold adjustment and positioning device for internally threaded seamless steel pipes is disclosed. , so that the processing and manufacturing of seamless steel pipes wi...
