Abstract
A cold isostatic pressing and turning method for machining roller collar string without binder powder includes such steps as removing the soft jacket from hollow billet with mandrel, fixing it to lathe, fastening the hollow billet to the mandrel turning it to obtain integral roller collar string, further turning it to obtain roller collar pieces one by one while adding rubber washers for each roller collar, and detaching them. Its advantages are high productivity and low cost.
Description
Do not mix rubber powder end isostatic cool pressing pipe bunching cushioning production method, belong to the powder metallurgy production field.Be applicable to of the turning of cold rolling strap rib steel with the collars base.
Not mixing rubber powder end cold isostatic compaction is the forming technique of a kind of advanced person in the field of powder metallurgy.Forming process is: pack into soft mode and place liquid medium of powder, pressurize to medium by high-pressure pump, thereby the powder in the soft mode be pressed into the shape of setting.This forming method has been compared following advantage with traditional punching block mechanical forming method: powder is comprehensive pressurized in soft mode, and the press time can be controlled arbitrarily, and the barometric gradient in the soft mode is little, eliminated the powder base since density contrast form give crackle.Therefore, same powder is higher than mechanical-moulded powder base intensity with the powder base intensity of cold isostatic compaction.For with a kind of powder, the compact strength of mixing rubber powder is higher than the compact strength of not mixing glue.Do not use cold isostatic compaction so do not mix the rubber powder end more.Another advantage of not mixing the glue cold isostatic compaction is a production technology of having simplified sintered metal product.Omitted the Degumming Procedures that powder is mixed glue and powder base.Both reduced production cost, avoided mixing adhesive process again the pollution of product and the quality problems that cause thus.Though do not mix rubber powder end cold isostatic compaction so many advantage is not arranged, for the batch process of small size workpiece certain difficulty is arranged, this is main lower because do not mix the intensity of rubber powder end pressed compact.And will be processed into big powder compact a plurality of little workpiece base the time, exist income rate low, problems such as cost height.Be pipe for example with not mixing glue cemented carbide powder cold isostatic compaction, when being reprocessed into the cold rolling strap rib steel with the collars base, as will be on the pipe outside core rod on the lathe every cutting-out a slice collars base just unload series of processes such as then needing repeatedly to drive, stop, unloading, pressed compact are retightened at once down.Production efficiency is low, and if first car becomes the embryo of collars base not cut off earlier, cut off again after waiting sintering.Because sintering cemented carbide base hardness is very high, this makes each collars increase by 200 yuan cost, has reduced competitiveness of product.
The object of the present invention is to provide a kind of rubber powder end isostatic cool pressing pipe bunching cushioning production method of not mixing, the high inexpensive annular sintered metal product of this method energy production matter, it can not only be enhanced productivity, and guarantees the serviceability rate of collars base, and can reduce collars base production cost.
Based on above-mentioned purpose, the present invention does not mix rubber powder end isostatic cool pressing pipe bunching cushioning production method, it is characterized in that: the pipe that will slough the belt carcass axle of Soft Roll cover is loaded onto lathe, dop with lathe clips mandrel and withstands with addendum cone, then with hard rubber circle and adhesive plaster with the two ends jam-packed of pipe and be fixed on the mandrel, start lathe subsequently, with carbide alloy and adamantine compound tool, the pipe car is become the collars base of a string disjunctor, be cut into the collars sheet with lathe tool again, every cutting-out a slice just adds a ring-type soft rubber pad at knife-edge part, downcut so one by one and go, till whole pipe all is cut into piecemeal collars sheet, and then unloading together, the collars sheet that cuts through sintering, high temperature insostatic pressing (HIP), after the mill processing, promptly become the carbide roll ring that steel rolling is used.
Compared with prior art, the invention has the advantages that: adopt this method to enhance productivity, guarantee the serviceability rate of collars base, and can reduce collars base production cost, and the good quality production performance is arranged.Thereby product profits tax per ton is higher 100,000 yuan than punching block compacted products; Product than the warp cutting reduces cost 70,000 yuan.This method is applicable to other cemented carbide powder goods such as roller shear cutter.
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is a production method work schematic diagram of the present invention.
1 is lathe among Fig. 1, and 2 is dop, and 3 is mandrel, and 4 is adhesive plaster, and 5 is the collars base, and 6 is lathe tool, and 7 is the soft rubber pad, and 8 is the vulcanite pad, and 9 is addendum cone, and 10 is chock plug.
Claims (1)
1, do not mix rubber powder end isostatic cool pressing pipe bunching cushioning production method, it is characterized in that: the pipe that will slough the belt carcass axle of Soft Roll cover is loaded onto lathe, dop with lathe clips mandrel and withstands with addendum cone, then with hard rubber circle and adhesive plaster with the two ends jam-packed of pipe and be fixed on the mandrel, start lathe subsequently, with carbide alloy and adamantine compound tool, the pipe car is become the collars base of a string disjunctor, be cut into the collars sheet with lathe tool again, every cutting-out a slice just adds a ring-type soft rubber pad at knife-edge part, downcut so one by one and go, till whole pipe all is cut into piecemeal collars sheet, and then together the unloading, the collars sheet that cuts through sintering, high temperature insostatic pressing (HIP), after the mill processing, promptly become the carbide roll ring that steel rolling is used.
