Abstract
The utility model relates to a dummy bar head of an aluminium alloy flat cast ingot, which is used for the casting of the aluminium alloy flat cast ingot. The dummy bar head is of a tray type single-casting. The utility model is characterized in that upper surface that the dummy bar head contacts with the bottom of the flat cast ingot is of a structure with a lug boss at the middle part and a protruding edge at the periphery. Since the dummy bar head of the utility model is adopted, the phenomena of facet bending generated in the casting process of the aluminium alloy flat cast ingot is effectively reduced, and the probability for happening the facet bending of the flat cast ingot is reduced from 3.88 percent to 0.77 percent. The probability for happening the facet bending of the flat cast ingot is greatly reduced, thereby the rate of finished products of the flat cast ingot is also greatly improved from 93.99 percent to 98.26 percent.
Description
Technical field
The utility model relates to a kind of aluminium alloy flat ingot casting dummy bar head, is used for the casting of aluminium alloy flat ingot casting.
Background technology
In recent years, along with the extensive use of aluminium sheet strip and foil section product, market increases sharply to the demand of aluminium alloy flat ingot casting, and the enterprise that produces the aluminium alloy flat ingot casting is also more and more.At present, in actual production process, use traditional flat dummy bar head to carry out aluminium alloy casting mostly, water the aluminium alloy flat ingot casting regular meeting that casts out because of the crooked waste product that becomes of facet occurring.Produce and processing enterprise at the aluminium alloy flat ingot casting, the bending of flat ingot casting facet is a general and common phenomena, it also is an extremely nerve-racking agricultural technology problem of having a headache, not only influence is cast and the yield rate of the operation of rolling, but also causes unnecessary loss due to spoiled work, increase working strength of workers.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists at above-mentioned prior art, provides a kind of and can effectively solve the facet buckling phenomenon that produces in the aluminium alloy flat ingot casting casting process, improves the aluminium alloy flat ingot casting dummy bar head of the yield rate of flat ingot casting.
The purpose of this utility model is achieved through the following technical solutions.
A kind of aluminium alloy flat ingot casting dummy bar head, its dummy bar head is the pellet type single-casting; It is characterized in that it is that the centre has boss, periphery has the convex edge structure with the upper surface that flat ingot casting bottom contacts.
A kind of aluminium alloy flat ingot casting dummy bar head of the present utility model, the upper surface that it is characterized in that its flat ingot casting bottom contact has boss, periphery to have the depression groove depth bottom that forms between the convex edge is 5-10m for middle.
The utility model adopts cast steel material, and the cast steel molten iron is cast out overall profile by the wooden model founding, carries out the machined final molding.Because the size on the surface of aluminium alloy flat ingot casting dummy bar head and the flatness of lower surface are had required precision, so in machining process, elder generation is upper surface fixedly, lower surface is rough milled, upset afterwards, following surface is thick benchmark milling upper surface, and last is that smart benchmark is finally processed lower surface with the upper surface that mills.There is required distance on upper surface bossing and each limit, add man-hour, and the lower surface that fixedly mills requires to rough mill out basic size according to drawing and gets final product.
The utility model is compared with the flat ingot casting dummy bar head of tradition, it still is rectangle generally with the upper surface that aluminium liquid contacts, but not flat, but be designed to be made at the bottom of low middle high " projection " shape in both sides, increased the contact area of flat ingot casting bottom and dummy bar head in the casting process, strengthened stability, effectively preventing the bending in casting process, cause of flat ingot casting owing to tilting.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of aluminium alloy flat ingot casting dummy bar head, its dummy bar head is pellet type single-casting 1; The upper surface that contacts with flat ingot casting bottom is that the centre has boss 5, periphery has convex edge 3 structures.The upper surface of its flat ingot casting bottom contact has boss, periphery to have the recessed groove 4 dark bottoms that form between the convex edge is that 5-10mm is slightly variant because of the specification difference of flat ingot casting for the centre).2 is lifting eye among the figure.
Adopt dummy bar head of the present utility model, reduced the facet buckling phenomenon that produces in the aluminium alloy flat ingot casting casting process effectively, the crooked odds of flat ingot casting facet has dropped to 0.77% by 3.83%.
Because the crooked odds of flat ingot casting facet reduces greatly, the yield rate of flat ingot casting also greatly improves, and the yield rate of flat ingot casting has brought up to 98.26% by 93.99%.
Claims (2)
1. aluminium alloy flat ingot casting dummy bar head, its dummy bar head is the pellet type single-casting; It is characterized in that it is that the centre has boss, periphery has the convex edge structure with the upper surface that flat ingot casting bottom contacts.
2. a kind of aluminium alloy flat ingot casting dummy bar head according to claim 1, the upper surface that it is characterized in that its flat ingot casting bottom contact has boss, periphery to have the depression groove depth bottom that forms between the convex edge is 5-10mm for middle.
