Problems solved by technology

The existing equipment for making heads of cold-drawn steel pipes mainly uses air hammers, splint hammers, and rotary forging machines. The structures are complex, the precision of making heads is low, and the heads of the steel pipes are tied to death, which brings inconvenience to subsequent processing, and the The head is long and the metal loss is large
For medium and large diameter steel pipes, the existing head making equipment is powerless

Embodiment Construction

[0010] Such as figure 1 , 2 As shown, it is a roller spinning device of a steel pipe head making machine, which includes a self-centering three-jaw chuck 12, and one side of the self-centering three-jaw chuck 12 is connected with three jaws 13, and each jaw 13 is respectively The roller 16 is connected by a round nut 14 , a bearing gland 15 , and a third single row tapered roller bearing 17 . The three rollers can be configured in different positions to form different pass patterns (replacing the rollers can realize the wide group spacing of steel pipes).

[0011] The other side of the self-centering three-jaw chuck 12 is connected to the driving device through a flange, and the steel pipe 1 to be made is inserted into the self-centering three-jaw chuck 12 through an oil cylinder.

Abstract

The invention discloses a roller spinning device for a steel tube pointing machine, which relates to a steel tube pointing machine, particularly a roller spinning device for a pointing machine. The roller spinning device comprises a three-jaw self-centering chuck, wherein one side of the three-jaw self-centering chuck is connected with three clamping jaws, and each clamping jaw is respectively connected with a roller. The invention has the advantages of simple, reasonable and compact structure, easy production and manufacturing and high precision. The invention enhances the precision and efficiency of cold-drawn steel tube pointing, can be widely used for pointing of medium / large diameter cold-drawn seamless steel tubes, is especially suitable for large-tonnage hydraulic drawbenches to produce seamless steel tubes, and has high popularization value.

Description

technical field [0001] The invention relates to a steel pipe head making machine, in particular to a roller spinning device of the head making machine. Background technique [0002] The steel pipe head making machine is suitable for the cold drawn seamless steel pipe industry, especially for the medium and large diameter cold drawn seamless steel pipe industry. It is mainly used for making the steel pipe head before cold drawing. It belongs to the technical field of seamless steel pipe manufacturing equipment . The existing equipment for making heads of cold-drawn steel pipes mainly uses air hammers, clamping plate hammers, and rotary forging machines. The structures are complex, the precision of making heads is low, and the heads of the steel pipes are tied to death, which brings inconvenience to subsequent processing, and the The head is longer and the metal loss is large. For medium and large diameter steel pipes, the existing head making equipment is powerless. Conte...
