Abstract
The utility model belongs to an extrusion female die and particularly relates to improvement on an extrusion female die structure adopted in the first working procedure of extruding an aluminum sheet into a blank tube by an extruder in the production of an aluminum hose for medicine packaging. In the female die for the medical aluminum hose, a die holder is of an up-and-down split structure; a tungsten steel ring is pressed into an inner hole of an upper die holder; a die core is in close fit with the inner hole of a lower die holder; and the upper part of the die core is in close fit with an inner hole of the tungsten steel ring. In the utility model, the tungsten steel ring is pressed into the upper die holder to form a three-layer prestressed combined die; under the condition of unchanged sizes of the outer diameter and the inner diameter of an original female die, the strength of the structure is 1.4 times of the strength of the original structure, and the Rockwell hardness is improved to 62-65 from the original 50. With the adoption of the structure, a great amount of high-grade alloy steel materials can be saved; and when the die is worn, only the tungsten steel ring needs to be replaced, but the integral die does not need to be replaced. For the split female die, not only is the treatment process more reasonable, the using performance is strengthened, but also the production cost of the die can be reduced, and the service life of the die is prolonged.
Description
Technical field
The utility model belongs to a kind of Extruding die, during particularly the wrapping aluminium soft tube of medicine is produced, and the improvement of the Extruding die structure that first procedure is an aluminium flake through being squeezed into shell and adopting.
Background technology
During the wrapping aluminium soft tube of existing medicine was produced, to be aluminium flake be squeezed into the die structure that agent that shell adopts is pressed through extruder to first procedure, is solid die substantially, is made up of die holder and core rod; The structure of core rod is not considered the reasonability of Technology for Heating Processing, and core rod surface of internal cavity hardness is not enough, almost all will change 1-2 when every work, and when producing continuously in a large number, the die holder structure does not guarantee the requirement of hardness and intensity, can not meet the needs of production.
Summary of the invention
The purpose of this utility model is to solve the problem that above-mentioned prior art exists, and provides a kind of improvement medicinal aluminium soft tube die.The technical solution of the utility model is: a kind of aluminium soft tube die, die holder are split type up and down, are pressed into the wolfram steel circle in the upper bolster endoporus: die shoe endoporus tight fit core rod, core rod top and wolfram steel circle endoporus tight fit.
The beneficial effects of the utility model are: upper bolster is pressed into the wolfram steel circle, three layers of prestressing combination mould have so just been formed, under original mould external diameter and the constant situation of internal diameter size, the intensity of this structure is 1.4 degree of original structure intensity, and Rockwell hardness is brought up to 62-65 from original 50 times.Structure of the present invention can be saved a large amount of high-grade alloy steel materials, and die wear only need be changed the wolfram steel circle of wearing and tearing, needn't integral replacing, the split type die of the present invention, not only treatment process is more reasonable, has strengthened serviceability, and can reduce the production cost of mould, improve the service life of mould.
Description of drawings
Among the figure, 1 is the wolfram steel circle, and 2 is upper bolster, and 3 is die shoe, and 4 is core rod.
The specific embodiment
Medicinal aluminium soft tube die, die holder are split type up and down, are pressed into wolfram steel circle 1 in upper bolster 2 endoporus, die shoe 3 endoporus tight fit core rods 4, core rod 4 tops and wolfram steel circle 1 endoporus tight fit.
Claims (1)
1. aluminium soft tube die, its technical characterictic is: die holder is pressed into the wolfram steel circle, die shoe endoporus tight fit core rod, core rod top and wolfram steel circle endoporus tight fit for split type up and down in the upper bolster endoporus.
