Abstract
The utility model provides an internal-cooling combined ring rolling core shaft. The internal-cooling combined ring rolling core shaft comprises a connecting base, a core shaft, a core shaft fixing base, a pressing sleeve and a pressing cover, wherein a circular bulge is arranged on the right side of the outer wall of the core shaft; a circular concave table is arranged on the right side of the inner wall of the core shaft fixing base; the core shaft fixing base is sleeved on the core shaft through the circular concave table and the core shaft fixing base and the core shaft are put inside a circular groove on the left side of the inner wall of the connecting base; a step-shaped circular platform is arranged on the outer wall of the core shaft fixing base; a circular bulge is formed on the left side of the inner wall of the pressing sleeve; the pressing sleeve is sleeved on the core shaft fixing base through the circular bulge; and the pressing cover is sleeved on the pressing sleeve and tightly fixed on the outer wall of the connecting base through a bolt on the end surface of the pressing cover. The internal-cooling combined ring rolling core shaft has the advantages of simple structure, convenience in installation and detachment, low mould cost and long service life and is particularly applicable to a vertical ring rolling mould.
Description
Technical field
The utility model belongs to vertical Ring Rolling Machine mould applications, especially relates to the mould design that the ring core axle is rolled in a kind of inner-cooled combination.
Background technology
Mandrel is the rapid wear mould that roll over to expand in the operation, and traditional mandrel is designed to working portion and the lathe coupling part is an one, owing to roll over and expand the excessive mandrel phenomenon that fractures that causes of strength and happen occasionally, the dismounting of the back mandrel that fractures is difficulty very in the actual production.In addition, after the concentrated wear of mandrel working portion, mandrel also must integral body be scrapped.Because whole mandrel does not have inner cooling, can cause mould initial failure yet.Therefore, whole mandrel exists die life short, problems such as die cost height.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy installation and removal, the ring core axle is rolled in die cost a kind of inner-cooled combination low, high life, especially is fit to vertical Ring Rolling Machine mould.
The technical solution of the utility model is:
The ring core axle is rolled in a kind of inner-cooled combination, comprises Connection Block, mandrel, mandrel holder, clamping sleeve and friction top, and the outer wall right side of described mandrel is provided with annular protrusion; The inwall right side of described mandrel holder is provided with annular concave platform, and is socketed on the mandrel by annular concave platform, and in mandrel is placed on the annular groove in Connection Block inwall left side; The outer wall of described mandrel holder is provided with stepped ring-shaped platform; The inwall left side of described clamping sleeve is provided with annular protrusion, and is socketed on the mandrel holder by annular protrusion; Described friction top is socketed on the clamping sleeve, and by the bolted on the friction top end face on the outer wall of Connection Block.
Further, described Connection Block adopts non-mould steel to make, and described mandrel and mandrel holder adopt high performance hot-work die steel to make.
Further, described clamping sleeve outer wall and friction top inwall all take the form of inclined plane, and friction top is socketed on the clamping sleeve by the inclined-plane.
Advantage and the good effect that the utlity model has are:
1, mandrel easy installation and removal only needs screw with the clamping sleeve end face unclamp and gets final product, and is time saving and energy saving.
2, cooling water can reduce mold temperature and loss in the mandrel internal flow, prolongs die life.
3, only need to change mandrel after the mandrel wear and get final product, miscellaneous part can continue to use, and die cost reduces by 50%.

The specific embodiment
Shown in Fig. 1～2,
The technical solution of the utility model is:
The ring core axle is rolled in a kind of inner-cooled combination, comprises Connection Block 1, mandrel 2, mandrel holder 3, clamping sleeve 4 and friction top 5, and the right-hand member of described Connection Block 1 is installed on the machine tool; The outer wall right side of described mandrel 2 is provided with annular protrusion; The inwall right side of described mandrel holder 3 is provided with annular concave platform, and is socketed on the mandrel 2 by annular concave platform, and in mandrel 2 is placed on the annular groove in Connection Block 1 inwall left side; The outer wall of described mandrel holder 3 is provided with stepped ring-shaped platform; The inwall left side of described clamping sleeve 4 is provided with annular protrusion, and is socketed on the mandrel holder 3 by annular protrusion; Described friction top 5 is socketed on the clamping sleeve 4, and by the bolted on friction top 5 end faces on the outer wall of Connection Block 1.
Described Connection Block 1 manufactures according to the different model lathe, and make inside hollowly is convenient to passing through of cooling water, and Connection Block 1 adopts non-mould steel to make.
Described mandrel 2 inside have cooling water to pass through, and mandrel 2 and mandrel holder 3 all adopt high performance hot-work die steel to make.
Described clamping sleeve 4 outer walls and friction top 5 inwalls all take the form of inclined plane, and friction top 5 is socketed on the clamping sleeve 4 by the inclined-plane.
It is as follows that the utility model is applied in the blue or green specific operation process of forging on the D51-250 Ring Rolling Machine of producing in Qingdao:
In rolling over the expansion operation, can lower the temperature to parts by the cooling water of Connection Block 1 and mandrel 2 internal flows.
More only need unclamp the bolt on friction top 5 end faces during mold exchange, unload clamping sleeve 4 and friction top 5, change mandrel 2 and get final product.
The utility model provides a kind of simple in structure, easy installation and removal, die cost a kind of inner-cooled combination low, high life to roll over the ring core axle, especially is fit to vertical Ring Rolling Machine mould.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limit practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
