Abstract
Of the present invention a kind of steel pipe heat seal method during with hollow-core construction workpiece such as steel pipe processing blind hole cover, small-sized deep hole covers is provided; This method is that steel pipe is fixed in the lathe spindle hole; Open lathe, steel pipe is rotated with 1200-1400 rev/mins speed, using cutter head is that circular-arc lathe tool is beginning penetration of a cutting tool apart from steel pipe end face 3-4mm to be processed place; After lathe tool and tube fraction make the steel pipe heating softening; Cutter head shrinks steel pipe end face bore to be processed, up to sealing fusion to steel pipe end face to be processed center feed extruding gradually.Be exclusively used in the lathe tool of said method, comprise cutter head and knife bar, the operate portions of cutter head is a sphere, and the radius of sphere is 5mm.Steel pipe heat seal method of the present invention, be prone to be grasped, economized in raw materials less investment, and is applied widely, has higher utilization and extention and is worth.
Description
Technical field
The present invention relates to a kind of processing method of hollow-core construction workpiece, specifically is a kind of heat seal method and special-purpose lathe tool with steel pipe processing hollow-core construction workpiece.
Background technology
At mechanical processing industry, can run into various parts needs processing, and blind hole cover, small-sized deep hole lid, the heat supply workpiece with hollow-core construction types such as combs is wherein just arranged.It is simple that this type workpiece seems; But do not have better means, can only adopt traditional processing technology, as with solid round steel through boring, bore hole and steel pipe welding plug etc.; The workpiece of this processes the above-mentioned type, operation is loaded down with trivial details, workload is big, spillage of material is many, aesthetic property is poor.This type workpiece quality only accounts for the 10%-20% of raw materials quality according to statistics, and electric power resource that process consumption is a large amount of and human resources cause great waste to raw material simultaneously, not only time-consuming, effort, but also takes material.
Summary of the invention
The purpose of this invention is to provide a kind of steel pipe heat seal method during with hollow-core construction workpiece such as steel pipe processing blind hole cover, small-sized deep hole covers.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is: a kind of steel pipe mouth-sealing method is fixed on steel pipe in the lathe spindle hole; Open lathe, steel pipe is rotated with 1200-1400 rev/mins speed, using cutter head is that circular-arc lathe tool is beginning penetration of a cutting tool apart from steel pipe end face 3-4mm to be processed place; After lathe tool and tube fraction make the steel pipe heating softening; Cutter head shrinks steel pipe end face bore to be processed, up to sealing fusion to steel pipe end face to be processed center feed extruding gradually.
Turner is in turning process, and the steel pipe workpiece of rotation and lathe tool produce relative motion and frictional heating at a high speed, and the temperature of steel pipe end face to be processed is raise.The size that friction generates heat is relevant with contact area, the squeezing action power size of lathe tool and steel pipe; The size of contact-making surface depends on the size of cutter head cambered surface; Squeezing action power is applied to the external force on the workpiece when being the lathe tool feed, contact-making surface and squeezing action power can be adjusted according to the concrete condition of workpiece.Through lathe tool the steel pipe of at a high speed rotation is applied external force, the steel pipe temperature can be elevated to rapidly about 1500 ℃, this moment material hardness reduce greatly, plasticity increases, and handles lathe tool the steel pipe end face is pushed, softening steel pipe bore shrinks gradually, merges up to sealing.
The present invention also provides a kind of lathe tool that is exclusively used in said method, comprises cutter head and knife bar, and the operate portions of cutter head is a sphere, and the radius of sphere is 5mm.The operate portions of cutter head is designed to the rubbing action that sphere can be given full play to lathe tool, can not cause damage to steel pipe again simultaneously.
Steel pipe heat seal method of the present invention, be prone to be grasped, economized in raw materials less investment, and is applied widely, has higher utilization and extention and is worth.
Description of drawings
Fig. 1 is the structural representation of lathe tool of the present invention.
Among the figure, 1-cutter head, 2-knife bar.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done and to specify.
A kind of steel pipe heat seal method of the present invention is that steel pipe is fixed in the lathe spindle hole, opens lathe; Steel pipe is rotated with 1200-1400 rev/mins speed; Using cutter head is that circular-arc lathe tool is beginning penetration of a cutting tool apart from steel pipe end face 3-4mm to be processed place, and after lathe tool and tube fraction made the steel pipe heating softening, cutter head 1 pushed to the feed of steel pipe end face to be processed center; Steel pipe end face bore to be processed is shunk gradually, up to sealing fusion.
The lathe tool that is used for above-mentioned steel pipe heat seal method comprises cutter head 1 and knife bar 2, and the operate portions of cutter head 1 is a sphere.The radius of preferred cutter head 1 sphere is 5mm.Knife bar 2 can be made by No. 45 forgings and form; The material of cutter head 1 part is steel alloy YT15; Steel alloy is welded in the groove that knife bar 2 processes, the shape and size of cutter head 1 working portion through analyze, repetition test confirms that cutter head 1 part after welding can be used through the polishing moulding.
Below with the example that is processed as of blind hole cover, the present invention is further specified:
1. raw material selection Φ 45 * 4 hot rolled seamless steel tubes
2. Φ 45 * 4 * 80 steel pipes of sawing
3. in lathe chuck, clamp, each car of the inside and outside footpath of steel pipe is removed 1mm, make its inside and outside footpath identical with the interior external diameter of blind hole cover.
4. again workpiece is clamped, install the circular arc lathe tool, the lathe rotating speed is set to 1400 rev/mins.Open lathe, treat that the lathe rotating speed reaches setting value, rotate large and small planker, make the cutter head operate portions in beginning manual lateral feed apart from steel pipe end face 3-4mm place; Lathe tool applies certain external force to steel pipe, pushes, at a high speed the steel pipe and lathe tool mutual friction mutually of rotation; Steel pipe is extruded partial transient and just reddens, brightens, and temperature raises rapidly, continues slowly to cross feed; The steel pipe bore diminishes gradually, finally merges fully, reaches the purpose of sealing.The process of sealing only needs 1-2 minutes.
