Description
Technical field
The present invention relates to the continuously extruded technology of non-ferrous metal continuously extruded technology, especially copper alloy and equipment, for various non-ferrous metal section bars, wire rod, copper strap wire, copper bar, brass material and other nonferrous metal and alloy continuous extrusion production manufacture.
Background technology
Existing continuous extrusion cavity is by two kinds of structures, a kind of is whole cavity, be that whole cavity comprises that material blocking block is all to be made by a part, another kind is that material blocking block is an independent part, constitute a complete cavity together with cavity matrix, patent CN200610047955.8 provides a kind of combined cavity, material blocking block is manufactured to an individual part, when being damaged, material blocking block can change separately this material blocking block, and the material of material blocking block can be the material different from cavity matrix, therefore when greatly improving this cavity institute energy production product scope, also greatly reduce production cost.The cavity that CN200610047955.8 provides and the damage type of material blocking block are material blocking block deformation and fracture, and when material blocking block material is the materials such as pottery, carbide alloy, due to excessive temperature differentials before and after material blocking block, in the time of can causing material blocking block to use, within very short time, with regard to cracking, cannot use, therefore this material blocking block and cavity still can not be applied the continuously extruded of the copper alloy such with being similar to brass at present, continuously extruded being still of the copper alloy that current brass is such adopts the extruding of monoblock type cavity to produce, and exists above-mentioned not enough problem.
Summary of the invention
The present invention seeks to overcome above-mentioned deficiency, a kind of continuous extruder combined type cavity that pushes copper alloy is provided, simple in structure, low cost of manufacture, the operating cost of reduction equipment, not only can overcome the shortcoming of existing combined type cavity, can also be successfully applied to the continuously extruded of the so difficult extrded material of brass, realize the copper alloys such as brass and on traditional continuous extrusion device, be difficult to the continuous extrusion production that extruding is produced, there is significant economic benefit and social benefit.
The technical scheme that the present invention adopted is to achieve these goals: a kind of continuous extruder combined type cavity that pushes copper alloy, cavity is comprised of cavity matrix and material blocking block, on cavity matrix with the circular arc and the charging aperture that cooperatively interact with squeegee roller circular arc, in cavity matrix, mould is installed, material blocking block forms Combined stopping block by plug and back-up block, and plug is near cavity charging aperture, back-up block below plug and the two fit tightly, the height H of plug is less than 15mm, preferably 3-8mm.
The surface roughness Ra value on the composition surface of described plug and back-up block is less than 1.6 microns.
The height H 1 of described back-up block is greater than the more than 2.5 times of bar material diameter.
Described plug is formed by cobalt-base alloys, carbide alloy, pottery or cermet material manufacture.Be preferably high temperature resistant, the high-abrasive materials such as cobalt-base alloys, zirconia ceramics, silicon nitride ceramics and carbide alloy.
Described back-up block is to be manufactured by hot die steel, high-speed steel or high temperature alloy.
The material of described cavity matrix is hot die steel or high temperature alloy, preferably H13 hot die steel and nickel base superalloy GH4169.
Compare with existing similar extrusion equipment, although the present invention has carried out improvement among a small circle, there is outstanding substantive distinguishing features and significant technique effect:
(1) material blocking block of the present invention adopts upper and lower fabricated structure, be designed at least 2 sections, due to whole material blocking block only near cavity charging aperture one side very little one section in high-temperature area, the remainder of material blocking block is to conduct thermograde of self-assembling formation by heat, and the fragile material of pottery and so on can ftracture because of temperature stress owing to being subject to compared with the large temperature difference, the present invention, by the partition of geometry, dwindles the temperature difference of plug itself, avoids material blocking block because self temperature difference causes cracking.
(2) plug height of the present invention is less, so the temperature difference of plug itself is less, utilizes plug and back-up block two block structures to discharge the temperature stress of material blocking block itself; When plug adopts the resistant to elevated temperatures fragile material of pottery or carbide alloy and so on, can not cause because of the excessive temperature differentials of self self cracking, application the present invention, plug is under certain service condition, can use ceramic material, carbide alloy or the cobalt-base alloys (stellite) of can be high temperature resistant and can be wear-resisting, therefore can greatly improve combination material blocking block withstand high temperatures, high pressure, wear-resisting ability, realize the continuously extruded of brass.
(3) charging aperture of plug of the present invention and cavity matrix is in material blocking block one side, and plug should be concordant with cavity matrix, and plug and cavity matrix composition surface should be seamless at charging aperture place, avoids metal stock to enter gap and causes plug to be lifted.
(4) back-up block of the present invention is arranged on cavity matrix, and its front end near cavity charging aperture is plug, and its end is the support on cavity.Back-up block should keep substantially parallel with the contact-making surface of the supporting surface of plug contact end face and back-up block and cavity matrix, guarantee that cavity matrix is enough to the support strength of back-up block, and back-up block is at the height dimension of plug direction, should be greater than the more than 2.5 times of bar material diameter, to guarantee that back-up block has enough shear strengths.
