Abstract
The invention relates to a method for using roller mould with shaping chamber whose four rollers are vertically front and back, horizontal cross combination or eight rollers crossed front and back and horizontal cross combination to draw wire of titanium and titanium alloy. Wherein, it thermally processes or cold processes the titanium and titanium alloy wire, to process round section or non-round section ones, to obtain the titanium and titanium alloy material with high surface quality and high efficiency.
Description
Technical field
The present invention for a kind of be applicable to produce have great surface quality, the processing method of high finished product rate, high efficiency, titanium or titanium alloy silk material that single-deck silk material weight is big.
Background technology
Titanium or titanium alloy has performances such as high strength, high specific strength, superior corrosion resistance and biocompatibility, in many fields extensive use of national economy and social life.In the production of China circular section or on-circular cross-section (abnormal shape) titanium or titanium alloy silk material, generally use method rolling or the fixed die drawing, it is rolling that to have processing technology simple, the production efficiency height, product specification is various, the big advantage of single-deck silk material weight, but shortcoming also is conspicuous, investment of production equipment and floor space are big, product size is difficult to control, product surface quality relies on process control and blank state in early stage, moreover it is less to have a blank substance that feeds intake relatively for titanium or titanium alloy, cost an arm and a leg, the characteristics of processing technology and process control complexity, this processing method can only be as the production of silk material blank in early stage.The fixed die drawing has investment and site condition requires the advantage low, that product size is controlled easily, product surface quality is high, but little, the easy sticking to mould of its passage processing capacity, production efficiency is low, range of product size is narrow, spillage of material is big, mould and lubricating system are had relatively high expectations, and can only produce as small-scale, price height, the demanding special silk material of size table surface accuracy.
The present invention's " a kind of titanium or titanium alloy processing method for high surface quality filament stock ", be on the basis of comprehensive pair rolling and fixed die drawing method for processing advantage, utilization have before and after two groups of four rollers of roll-type mould of certain die cavity vertically and four groups of planche cross combination or eight rollers before and after intersect vertically and planche cross makes up and carries out the roller die wire-drawing technology that titanium or titanium alloy silk material is processed, by selecting suitable material hot-working of titanium or titanium alloy silk or cold working production technology, can carry out the processing of circular section or on-circular cross-section (abnormal shape) titanium or titanium alloy silk material, and can process and have great surface quality, high finished product rate, high efficiency, the titanium or titanium alloy silk material that single-deck silk material weight is big.
Summary of the invention
The roller die wire drawing is a kind of plastic deformation method between the rolling and fixed die drawing between tradition, has many advantages of both processing methods, with both identical point is arranged, but also difference to some extent.
The rolling silk of roller die wire drawing and tradition material is compared identical point: similar on instrument and machined material form to the special-shaped silk material that has forward pull; Difference: the roller die wire drawing is a material active, drives roller turn.Rolling is the roll active, drives material and enters die cavity.So the distribution of the frictional force on contact-making surface is just different with effect, be relative rolling between a material and roller, skin-friction force is little, is relative slip between silk material and roller during drawing, and skin-friction force is big.Drawing in the three-dimensional stress, compression ratio are just different like this.
The roller die wire drawing is compared identical point with the hot candied material of conventional fixed die drawing: the stress and strain state basically identical on the material deformation cell cube all is that a material is to stretch in axial action, and other both directions are compressions; Difference: the roller die wire drawing be a material with roller between be relative rolling, skin-friction force is little.Be relative slip between metal material and roller during drawing silk material, skin-friction force is big.Drawing in the three-dimensional stress, compression ratio are just different like this, and tension descends in the roller die wire drawing, and compression rises, and stress state is transformed to improving metal material plasticity direction, make roller die wire drawing passage deformation extent than drawing height.
One of purpose of inventing this kind titanium or titanium alloy processing method for high surface quality filament stock is to utilize Dan Zusi cross combination of roll-type mould or two groups eight the roller die wire-drawing technologies that front and back cross combination carrying out titanium or titanium alloy silk material is processed with certain die cavity, by select suitable material hot-working of titanium or titanium alloy silk or cold working production technology, can process to have great surface quality, high finished product rate, high efficiency, titanium or titanium alloy silk material that single-deck silk material weight is big.
Invent this kind titanium or titanium alloy processing method for high surface quality filament stock purpose two be that the roller die Wire Drawing has changed the friction law between mould and machined material, reduced frictional force and the required tensile force of wire drawing between silk material and mould, die-face only needs lubricating oil simply to lubricate or does not need to lubricate, the die surface wearing and tearing are little, wear surface disperses, and can avoid the stress of mold cavity sharp corner to concentrate the significant prolongation die life.For the wire drawing of easy sticking to mould, difficult distortion titanium or titanium alloy, the roller die wire drawing has more not sticking to mould, the easy advantage that is shaped.
Invent this kind titanium or titanium alloy processing method for high surface quality filament stock purpose three be hot-working and the cold working that the roller die wire drawing can be carried out circular section or on-circular cross-section (abnormal shape) titanium or titanium alloy silk material.Hot-working titanium and alloy wire pass reduction can reach 60%, and processed finished products silk material few surface defects, ovality is good, size is accurate, and single-deck silk material weight can reach 200 kilograms.The distortion of cold working titanium or titanium alloy silk material evenly, residual stress is little, pass reduction is big, can reach 30% for pure titanium or beta titanium alloy silk material pass reduction especially, and processed finished products silk material surface-brightening, ovality is good, size is accurate, and single-deck silk material weight can reach double centner.
Invent this kind titanium or titanium alloy processing method for high surface quality filament stock purpose four be that the roller die Wire Drawing is a kind of energy-saving production technology, can reduce processing and intermediate annealing passage, reduce tensile force and device drives power, reduce material and energy loss, improve yield rate.The roller die wire-drawing technology can with other process technologies of titanium or titanium alloy and equipment flexible combination, can form production line separately, also can be together to form production line with milling train, fixed die wire drawing or other process equipments, range of application is very extensive.
