Description
Technical field
The invention belongs to seamless steel pipe processing equipment technical field, be specifically related to a kind of seamless steel pipe heading machine.
Background technology
Aforesaid seamless steel pipe heading machine is also referred to as " machine for shrinking ", it it is the special equipment before seamless steel pipe drawing, its function is steel pipe head that is that one end of the seamless steel tube blank (i.e. hollow billet) before completing after the perforation process in road forms the diameter narrow contracting significantly less than seamless steel pipe body diameter and that maintain cavity, so that the clamp of drawbench carry out drawing when clamping steel pipe head.
The shape of cross section of the steel pipe head that prior art is formed in one end of seamless steel pipe is mostly for the shape of ω (Omega), although what the steel pipe head of this shape can meet the clamp of drawbench clamps requirement, but owing to steel pipe head is without through hole, thus cause trouble to the pickling in rear road, specifically, it is impossible to make to enter into the intraluminal pickle of seamless steel pipe entrainment of greasy dirt, miscellaneous bits etc. flow out.Then for facilitating pickling, generally it is drilled with a hole communicated with steel pipe tube chamber by means of special equipment at steel pipe head before the pickling process after drawing completes, " seamless steel pipe take the lead hole punched device " that typical example such as CN202185506U recommends.But it is by mean of independent equipment to be drilled with through hole at steel pipe head and can increase quantity and the technological process of use equipment undoubtedly, and affects steel pipe working (machining) efficiency.
If making steel pipe head maintain the steel pipe head axially extending bore that diameter reduces and with seamless steel pipe tube chamber communicates while using the steel pipe head forming narrow contracting implementing to take the lead to one end of seamless steel pipe, then aforementioned technical problem just can solve." the steel pipe heading machine " that Chinese invention patent Authorization Notice No. CN102688923B provides not only can meet the requirement being axially centrally formed the steel pipe head axially extending bore that the tube chamber with seamless steel pipe communicates taking the lead but also making steel pipe head.But this CN102688923B still suffers from following shortcoming: one, after being positioned at perforation process due to operation of taking the lead, seamless steel pipe after perforation is referred to as seamless steel tube blank, and (industry custom is referred to as " hollow billet ", as follows), hollow billet temperature now is higher, although the remaining temperature utilizing hollow billet carries out taking the lead certainly can save the energy, but affect service life owing to the block of taking the lead fixing with the one end of arm of taking the lead subjects to the high temperature of hollow billet, if therefore block of taking the lead can be implemented cooling, then can extend its service life, but this patent does not provides the enlightenment of corresponding technology；They are two years old, due to only the most smooth in the bearing being arranged on main shaft, the support ring, the bulb in support ring that are arranged on bearing and being arranged between the spherical bearing taking the lead on the arm operation that keeps taking the lead under preferable lubricating status, but this patent does not provides the enlightenment of corresponding technology equally.
