Abstract
PROBLEM TO BE SOLVED: To provide a device for compressing and expanding metal materials with which sections and tubes are formed by compressing and expanding a metal bar. SOLUTION: This compressing and expanding device has a movable hollow die 2 which is engaged with a washer 4 through a spline 3. The washer 4 is engaged with a fixed ring 6 through a spline 5 and, on the other hand, the fixed ring 6 is supported with a thrust bearing 7 and also connected with a reverse rotation driving mechanism part. This reverse rotation driving mechanism part is engageable with a series of splines 10 which are mounted on the fixed ring 6 and also connected with a driving part. The diameter of the hole 12 in a housing 1 is made smaller than the outside diameter of the movable hollow die 2 and supplementary relief 13 is provided in the front part of this hollow die 2.
Description
Technical field
The present invention relates to a kind of set of tools of extrusion metal.
Background technology
The metal compression tool group of existing multiple pattern in the prior art, for example polish patent application No.174474 discloses a kind of compression tool group, use in conjunction direct extruding and two kinds of operations of additional external force strain.An additional plastic deformation occurs in the shear zone of product.Because model and product contact-making surface injustice have caused the inhomogeneous of product.The compression tool group of using all comprises a model that is arranged in shell at present, and in extrusion process, this model can not be finished any type of twist motion.Required extruding force is bigger, and product is even inadequately.
Summary of the invention
Extruding force when the objective of the invention is to reduce the metal extruding makes product more even simultaneously, for this reason, has proposed a kind of novel metal compression tool group.
Set of tools according to the present invention has a motility model, it is by a key and a packing ring interlock, and packing ring is by key and tensioning ring interlock, and tensioning ring supports by a thrust bearing, and tensioning ring combines with the device of a generation reciprocal movement at the same time.The hole of a diameter less than the model external diameter arranged in this external model overcoat, and an auxiliary unloading hole is arranged at the model antetheca.
Till now, the maintenance of each pressure that material is exerted one's influence and determine to depend on the increase of material deformation degree and deformation extent, set of tools of the present invention makes that extrded material becomes possibility, the reduction of determining to depend on deformation extent and process temperature of described pressure under the situation that each pressure that material is exerted one's influence reduces.
The hole littler than model external diameter that use puts outside model, material is squeezed into the bad result in the part loose fit hole when having reduced rotation.
Description of drawings
An embodiment of set of tools of the present invention as shown in drawings, wherein Fig. 1 is a top view, Fig. 2 is the axial side view.
The specific embodiment
This set of tools is made of model overcoat 1 motionless during extrusion process and motility model 2, and model 2 is by a key 3 and packing ring 4 interlocks, and packing ring 4 is by a key 5 and tensioning ring 6 interlocks.Tensioning ring is by 7 supportings of a thrust bearing.And tensioning ring 6 combines with a device 8 that produces reciprocal movement.For example it can be one be installed in gear ring 10 engagement on the tensioning ring 6 and tooth plate bar 9 arranged with a driver 11 links.The hole 12 of a diameter less than model 2 external diameters arranged in overcoat 1, and an auxiliary unloading hole 13 is arranged in model 2 the place aheads.
When extruding action beginning, be extruded material and arrive external trepanning 12, then arrive the auxiliary unloading hole 13 in the model.Reciprocal movement is transferred to by tensioning ring 6, packing ring 4 and model 2 and is extruded on the material, and it is processed to be extruded auxiliary unloading hole 13 places that material is fixed in the model 2, and the gratifying state that is stressed is provided, and the energy consumption of extrusion process is reduced.
Reverse movement only is sent between the departure date on the model 2 squeezing into.Reverse and be not less than 0.5Hz, amplitude with frequency and be not more than+120 ° endless form or realize with the continuation mode that rotating speed is higher than per second 0.1 and changes.Frequency of reversing and amplitude depend primarily on size, speed and the temperature that the cross section reduces during the extruding, also depend on the kind that is extruded material.
Device extruding force according to the present invention reduce be because, in forcing the state warped regions that changes deformation method, be shaped, therefore under the distribute bits shifting state of difference, make permanent process implement to become possibility.
The feature of products obtained therefrom is: compare with conventional extruded technology products obtained therefrom, have good uniformity machine The tool performance is more superior.
