Abstract
The invention relates to a pull boring combined cutter which comprises a floating boring cutter, a floating cutter row, a chambering cutter, a copper sleeve, a claw type spring, a cutter rod, a boring rod and elastic wood. In the invention, the cutter rod is arranged on the rear part of the boring rod; the front part of the cutter rod is provided with the claw type spring and fixed by adopting the copper sleeve; the middle part of the cutter rod is provided with the boring cutter; the floating boring cutter and the floating cutter row are arranged on the rear part of the cutter rod; a plurality of axial slots are arranged on the floating cutter row; and the elastic wood is arranged in the axial slots of the floating cutter row. The method effectively reduces the production cost, improves the stability of the cutter, guarantees the coaxiality and the surface roughness while processing an inner hole of a pipe and improves the cutting efficiency.
Description
Technical field:
The present invention relates to a kind of cutting tool of processing metal pipeline, what particularly relate to a kind of deep hole reaming draws the bore hole gang tool.
Background technology:
At present, production application is in the heat-resisting alloy centrifugal casting tube of materials such as HK40, the HP-Nb of chemical industry furnace, ZG50Cr28Ni48W5 on the market, diameter 45-300mm, wall thickness 3.5-15mm, length 4-6 rice, conventional process of the same trade is: the boring bar afterbody is adorned a broad and is carried out reaming, and roughness reaches 12.5 microns.Expanded Kong Houzai and changed floating blade row, floating cutter is increased to the 3.2-1.6 micron with the hole roughness.There is following defective in this processing method commonly used:
(1) broad does not have the guiding of centering, and the easy sideslip of deep hole processing, wall thickness deviation cause pipe to scrap greater than 0.5mm.
(2) processing at twice, twice dress cutter, length consuming time, efficient are low.
(3) floating blade row gib block adopts carbide quartz welding, and grinding machine is milled to given size on the needs, processing request height, cost height.
Summary of the invention:
Purpose of the present invention will provide a kind of bore hole gang tool that draws exactly, it can satisfy the high request to this heat-resisting alloy centrifugal casting tube processing, the object of the present invention is achieved like this, a kind of bore hole gang tool that draws, formed by floating boring tool, floating blade row, cornish bit, copper sheathing, pawl formula spring, knife bar, boring bar, elasticity timber, it is characterized in that: knife bar is arranged on the rear portion of boring bar, be provided with pawl formula spring in the front portion of described knife bar, and adopt copper sheathing to fix, be provided with cornish bit at the middle part of knife bar; Floating boring tool, floating blade row are arranged on the rear portion of knife bar, and described floating blade row is provided with several axial grooves, is provided with elasticity timber in floating blade row axial groove; The front portion of boring bar and knife bar is set to hollow structure.The present invention has gang tool and installs, changes conveniently; Energy self-centering, converted products wall thickness deviation are less than 0.2mm, and the cost of charp tool reduces by 40%; Improve double production efficiency, reaming, the floating cutter one step completed advantage that reams.

Shell, 2. floating boring tool, 3. floating blade row, 4. cornish bit, 5. copper sheathing, 6. pawl formula spring, 7. knife bar, 8. boring bar, 9. elasticity timber, P are high-pressure cutting fluid
The specific embodiment:
The invention will be further described below in conjunction with accompanying drawing
In the drawings, a kind of bore hole gang tool that draws of the present invention, formed by floating boring tool, floating blade row, cornish bit, copper sheathing, pawl formula spring, knife bar, boring bar, elasticity timber, it is characterized in that: knife bar is arranged on the rear portion of boring bar, be provided with pawl formula spring in the front portion of described knife bar, and adopt copper sheathing to fix, middle part at knife bar is provided with cornish bit, floating boring tool, floating blade row are arranged on the rear portion of knife bar, described floating blade row is provided with several axial grooves, is provided with elasticity timber in floating blade row axial groove; The front portion of boring bar and knife bar is set to hollow structure.During concrete enforcement, deep hole boring main shaft is by (can prevent that pipe pulls, leaves the neutral gear cutter that the changes the outfit) clamping of special-purpose three-jaw and drive spun cast pipe and rotate, in the middle of the tube length direction and tail end with the support of centre frame roller, fix, the assurance pipe is coaxial with machine tool chief axis.Boring bar is fixed on the deep hole boring slide carriage, and is coaxial with main shaft, vertically moves on lathe bed.The boring bar stiff end connects the high-pressure cutting fluid pipeline, and knife bar is installed with double end square type screw thread in the working end, and the integral replacing gang tool is convenient.Pawl formula spring is clamped in earlier on the copper sheathing, and copper sheathing can freely rotate on knife bar, the outer pawl stretching spun cast pipe endoporus of pawl formula spring during work, and with knife bar self-centering, pawl formula spring, copper sheathing and spun cast pipe rotate synchronously.The centering that is slidingly matched of cornish bit and knife bar circular shaft, hole, square shaft, interporal lacuna cooperate transmitting torque, are tightened by floating blade row internal thread and knife bar end external screw thread, and cornish bit is anchored on the knife bar.Knife bar, cornish bit, floating blade row and boring bar relative fixed.Floating boring tool is long at feed side reconditioning 1/3rd swords, increases penetration of a cutting tool width 0.5mm.Elasticity timber adopts the mulberry support bar, and the mulberry bar is put in the floating blade row axial groove (can not strike disconnected) with hammering, notes the grain of wood during installation, is 135 degree with direction of advance.Guarantee to install the back batten in diametric(al) than the monolateral big 2-3mm of pore.Batten is tightly packed on the floating blade row, and the part bigger than pore can eliminate when pipe rotates also feeding automatically, can process inner hole wall by stretching simultaneously.
The interior aperture cornish bit roughing of spun cast pipe, the fine finishining of floating boring tool ream is once finished.Cornish bit should grind chip-breaker, guarantees not have long bits.Floating boring tool truncated sides reconditioning 1/3 long cutting edge adds full depth width 0.5mm.High-pressure cutting fluid is gone out by hollow boring bar, knife bar, and chip, floating boring tool ream chip that cornish bit is cut wash away at any time, takes away cutting heat and lubricated cutter, has guaranteed the durability of cutter.Because before being arranged, pawl formula spring centering supports cornish bit, the flexible batten centering in back is supported floating blade row, floating blade row gib block resiliency supported, adopt cheap material, do not need accurate processing, reduced production cost, improved the stability of cutter, guarantee pipe endoporus axiality, surface roughness, improved stock-removing efficiency.
