Description
Technical field
The present invention relates to a kind of tubing reducing formation process unit, be specifically related to a kind of fixed core pattern spinning undergauge new equipment the light-wall pipe precision diameter shrinkage.
Background technology
In the promotion that automobile, space industry receive weight reduction, reduce cost and improve the quality, increasing parts adopt the tubing manufacturing, advantages such as tubing undergauge part has efficiently, high-quality, economy, intensity is high, rigidity is big.Tubing is through pushing away the parts that manufacturing process such as shortening shape, drawing forming into can obtain different bores.But tubing is used to make automobile, space flight parts, and its forming mode mainly adopts pushing away of open die to shorten shape into.Increasingly high along with the shape and size required precision of undergauge part pushes away shortening shape into and pushed away by centreless and shorten shape into and developed into core and push away and shorten shape into.There is core to push away and shortens two types of the fixed core shaft type of shape, the mandrel formulas of floating into; Its mandrel has all got into pipe fitting before the beginning undergauge; The tube wall that mandrel will be in sizing area simultaneously during the pipe fitting reducing formation carries out crimp; This will cause pipe fitting to receive bigger axial pushing force, be prone to take place wall portion flexing buckling deformation.Push away and shorten shape into and mainly contain punching press undergauge method, mould pressing etc.The deformation extent of a reducing operation of punching press undergauge method is limited; Key constraints is force transmission region tube wall axial compressive force vertical unstability and ring-type wrinkle or local dent occur when excessive, or the deformed area tube wall is wrinkling because of the effect of tangential direction compression stress is prone to that the tangential unstability takes place.Can adopt the heating reducing for strengthening punching press undergauge operation, the device of the heating reducing of special, but equipment cost improves.The common all spinning machines of special of spinning undergauge method, cost is higher, is inappropriate for the production occasion of small batch pipe fitting.So need the design tubing undergauge new equipment that a kind of cost is lower, efficient is high, the product precision is high.
Summary of the invention
The objective of the invention is to overcome the above problem that prior art exists, a kind of fixed core pattern spinning undergauge new equipment is provided, simple in structure, product advantage of high precision that this device has.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention realizes through following technical scheme:
The accurate spinning undergauge of a kind of fixed core pattern light-wall pipe new equipment comprises location clamping part, pipe, spinning reducing formation and core shaping unit; Said location clamping part comprises chuck, and said chuck is connected with resilient sleeve; Said pipe insert said resilient sleeve together clamping at said chuck; Said spinning reducing formation and core shaping unit comprise fixed block, are connected with core in the said fixed block, and said fixed block one end is connected with the undergauge die, is provided with said core in the said undergauge die, and the said fixed block other end is connected with tailstock.
Further, said fixed block is connected through pin with said core.
Further, said fixed block is connected through screw with said undergauge die.
The invention has the beneficial effects as follows:
The accurate spinning undergauge of a kind of fixed core pattern light-wall pipe new equipment is provided; This device inserts resilient sleeve with pipe and is clipped on the chuck together and rotates on engine lathe or special spinning machine, and the spinning reducing die that is contained in the tailstock is done the longitudinal feed campaign; Utilize the spinning reducing die to accomplish the light-wall pipe reducing formation; Reducing finishes, and utilizes core to the shaping of reducing internal diameter when mould withdraws from, and can guarantee has the internal diameter precision of cooperation requirement and the fineness of inwall behind the undergauge.Because necking forming carries out gradually, so reduced the danger of undergauge power and force transmission region generation unstability greatly.Simultaneously; Because pipe rotates at a high speed with lathe spindle, spinning reducing die and pipe friction are generated heat, and reduce the resistance of deformation of tubing; Help the plastic deformation of deformed area material; The tube wall temperature of the force transmission region then temperature than the deformed area is low, and power transmission usefulness is unaffected, thereby can improve the deformation extent of single reducing.In the spinning process with oil lubrication and cooling when avoiding temperature too high, the danger that exists tubing and mould to bond.The present invention is reasonable in design, simple in structure, easy to operate, and product precision height and performance are good, and cost is low.The present invention can be contained in engine lathe or special spinning machine is accomplished the accurate spinning reducing formation of light-wall pipe, and the present invention mainly is suitable for the occasion that small batch is produced.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. specify as after.The specific embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
