Description
Technical field
The present invention relates to steel pipe inner wall quality treatment technical field, at a kind of steel pipe inner wall mass defect
Reason device.
Background technology
Accurate seamless stainless steel tubing tube-making process is extended, sizing by circular pipe blank, perforation, and annealing is cold rolling, and annealing is cold
Pull out, the operation such as normalizing and tempering composition, steel pipe inner wall mass defect common in process of production have crackle, infolding, scab, fiber crops
Hole, scratch and roughness are excessive etc..Steel pipe inner wall mass defect will delay to subsequent handling as processed not in time, to tubing
Can produce influence, follow-up pipe finished qualification rate can be largely effected on, in order to improve high added value precision small-caliber seamless steel pipe into
Material rate, is checked the inwall quality of pipe in operation and is checked in High Precision Cold, before the processing such as cold-drawn pair and to pipe
Surface defect need to carry out necessary treatment, so as to ensure that pipe orifice, without mass defects such as pits, is to ensure that used by steel pipe's production
The basic premise that blank conforms to quality requirements, is reduction of production cost, improves production efficiency, improves product qualified rate
One important measures.
The inwall quality surface defect of steel pipe is cleared up.Correlation internal face treatment both at home and abroad it is many using traditional pickling,
Shot-peening or ball blast, strip off the skin treatment.These traditional processing methods all have problems：First, the spent acid for being produced during pickling
Waste gas is very big to the physical effects of environment and direct labor, and its production environment is severe, and spent acid waste gas directly affects the sky of surrounding
Gas and water, soil, and the processing cost of spent acid is very high；2nd, shot-peening or ball blast produce substantial amounts of dust in process of production,
Cause the working environment of workshop equally very severe, and surface while cannot clean out completely, also result in inwall
Surface forms more pockmarks, directly influences the quality of tubing；3rd, it is to utilize electromechanical assembly to strip off the skin, and grinding head is selected conventional
Plane colyliform emery wheel grinding-head is processed steel surface grinding, such endoporus sanding apparatus when in use not only mechanicalness noise it is big,
Operating efficiency is not high, and the normal polishing caused by endoporus hole depth difference is not in place, and inner wall coarse after treatment, does not reach treatment effect
Really.Additionally, limited by structure and space, shot-peening, ball blast, strip off the skin for small-bore steel pipe inwall quality treatment substantially without
Method treatment.
CN201010267812 was once disclosed a kind of minimizing technology of steel tube surface oxide skin, while CN201110242186
Also a kind of descaling process of solid drawn tube surfaces externally and internally high-pressure water jet cold conditions was once disclosed, was disclosed in two patents
A kind of mode theory that steel pipe internal-surface treatment is carried out by the way of water jet, but disclose feasible facility and set
Standby structure.CN201310005329 once disclosed a kind of steel pipe inner wall cleaning device, was also that steel pipe is carried out by the way of water jet
Inner surface treatment, but the device structure is complicated and is adapted only to the treatment of the steel pipe inner wall of Large Diameter Pipeline, while single-piece steel pipe can only be carried out
Defect processing, it is impossible to realize to the batch processing of steel pipe.
Based on this problem, there is presently no a kind of good technology for the treatment of caliber pipe inwall surface quality and set
It is standby.Energy high efficiency, inexpensive solves the problems, such as caliber pipe inwall surface quality defect.
The content of the invention
For above-mentioned the deficiencies in the prior art, the technical problems to be solved by the invention are：How a kind of structure letter is provided
Single, easy to operate, treatment is quick, and high treating effect can be realized in the steel pipe of small-caliber steel pipe defect in inner surface batch processing
Wall mass defect processing unit.The small-caliber steel pipe refers to steel pipe of the bore less than less than 20 millimeters.
In order to solve the above-mentioned technical problem, present invention employs following technical scheme：
A kind of steel pipe inner wall mass defect processing unit, it is characterised in that including a housing for strip, set in housing
