According to the device, a plurality of quality problems in a machining process of a workpiece can be effectively solved, the quality of a product is improved, the service life of the product is prolonged, and the manufacturing cost is lowered.
Description
Technical field
The utility model relates to the industry fields such as metallurgy, papermaking, generating, particularly relates to a kind of nickel-base alloy furnace roller endoporus processing boring head device.
Background technology
External diameter Φ 350mm is widely used in the furnace rolls of the industries, particularly metallurgy industry such as metallurgy, papermaking, generating with interior nickel-base alloy furnace roller.Aspect processing characteristics: compare with carbon steel, nickel-base alloy belongs to difficult-to-machine material, machinability is poor, be mainly manifested in: plasticity is high, work hardening is serious, resistance to cutting is large, the alloy such as the austenitic nickel-based such as Cr33Ni50W16, Cr28Ni48W5Co3, its intensity and hardness and medium carbon steel are close, but plasticity is high, its percentage elongation surpasses the more than 2 times of 45 steel, and during machining, plastic deformation is large; During cutting nickel-base alloy, its cutting temperature is approximately higher 220 ~ 350 ℃ than 45 steel, and nickel-base alloy elevated temperature strength is high, and work hardening trend is strong, and work hardening layer hardness is high, and cutter easily weares and teares; Aspect the processing request of endoporus, be mainly manifested in: endoporus roughness is required as Ra3.2um; Wall thickness deviation requires in 0.2mm; The cylindricity of endoporus requires in 0.1mm; Endoporus machining adopts Roughing and fine machining to process at one time, cutting depth 3 ~ 5mm.Due to the load impacting in its use procedure and body of roll wall thickness deviation excessive, exceed setting, easily cause body of roll flexural deformation or expanded by heating, affect service life, and the probability that this phenomenon occurs is very large.In view of above situation, design and use endoporus processing boring head device and supporting cutter just seem very important.
Summary of the invention
The purpose of this utility model will provide a kind of nickel-base alloy furnace roller endoporus processing boring head device exactly, and it can solve the existing nickel-base alloy furnace roller endoporus processing existing above defect of boring head device.
The purpose of this utility model is achieved in that nickel-base alloy furnace roller endoporus processing boring head device, comprise boring head body, clamping screw, it is characterized in that: described boring head body interior is provided with blade row, adjustable floating boring cutter, the fluting place of described boring head body is provided with Common boring cutter, and fixed by clamping screw, on boring head body cylindrical, be evenly provided with the support of three guiding wood.
On adjustable floating boring cutter described in the utility model, be provided with adjusting bolt.
The material that guiding wood described in the utility model support adopts is wooden mulberry more closely.
The utility model can be avoided the generation that connects the bad quality conditions such as tool marks, body of roll wall thickness deviation and endoporus cylindricity are overproof, the whole roughness of endoporus is poor of batch in process.

In figure: 1, boring head body; 2, blade row; 3, guiding wood support; 4, adjustable floating boring cutter; 5, Common boring cutter; 6, clamping screw; 7, chuck; 8, workpiece; 9, centre frame; 10, boring bar.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing, nickel-base alloy furnace roller endoporus processing boring head device, comprise boring head body 1, clamping screw 6, it is characterized in that: described boring head body 1 inside is provided with blade row 2, adjustable floating boring cutter 4, the fluting place of described boring head body 1 is provided with Common boring cutter 5, and fixed by clamping screw 6, on boring head body 1 cylindrical, be evenly provided with three guiding wood support 3, on described adjustable floating boring cutter 4, be provided with adjusting bolt, the material that described guiding wood support 8 adopts is wooden mulberry more closely.During concrete enforcement, furnace roller body of roll clamping is also proofreaied and correct on deep hole boring machine, after start, workpiece rotates and carries out tool setting, prepare processing, during endoporus machining, workpiece carries out radial rotating, boring rod carries out axial feed motion, first Common boring cutter carries out boring to endoporus, and along with the increasing adjustable floating boring cutter of boring depth carries out smoothing to finished surface, the support of guiding wood is led on smooth inwall, simultaneously cutting fluid sprays by boring head desired location from boring bar, and cutter is carried out coolingly smear metal being sprayed to workpiece simultaneously.After endoporus machines, workpiece stops operating, and Common boring cutter and adjustable floating boring cutter are taken out from being positioned at workpiece end boring head, and then boring bar exits together with boring head.In " connecing tool marks " problem, original processing method, in process, in the middle of the serious fracture suddenly of Common boring cutter tool bit abrasion pipeline section, easily there is " connecing tool marks ", need the cutter head more renewing in time to continue processing, novel boring head device adopts adjustable floating boring cutter, the effect of playing finishing of internal diameter and improving inner wall roughness, has eliminated " connecing tool marks "; In body of roll wall thickness deviation and the overproof problem of endoporus cylindricity, original processing method easily makes guider serious wear in working angles, causes processing endoporus and is axially bending, by ultrasonic measurement, wall thickness is inconsistent, exceeds setting, and have a long way to go, the body of roll is difficult to revise.Novel boring head device, adopt the boring method that pushes away that bore hole Yu Fu hole carries out together, guiding wood adopts wooden mulberry more closely, be supported on the finished surface of smoothing and fully lead, effectively prevent from having processed endoporus and axially produce flexural deformation, thereby play the effect of controlling body of roll wall thickness deviation, improving endoporus cylindricity.In the poor problem of the whole roughness of endoporus, what deep hole boring machine adopted is water-emulsifiable liquid, when concentration of emulsion used is not enough, can affect cutter head cutting ability, causes whole roughness poor.Novel boring head device adds water-emulsifiable liquid in time to guarantee its concentration, when adjustable floating boring cutter is installed, mixes up and is locked to prevent that blade from retracting does not play the effect of finish turning endoporus after size.Adopt above boring head device can effectively prevent that such part from endoporus batch machining process, quality problems occurring, product first-time qualification rate originally only has 70% ~ 80%, can reach more than 95% now, daily output is increased to original more than 1.5 times, reduced energy resource consumption, in colleague, no matter be crudy, still process production capacity all in clear ahead level at present.
