Abstract
The utility model relates to a boss dummy block, which comprises a boss, a front lining and a rear lining. The boss is a cylindrical protrusion added to the end face of the front lining. Arrangement accords to the dummy blocks of different specifications, and thereby the boss dummy block is simple in structure. The thickness of discard is reduced effectively, and yield of extrusion production is increased.
Description
One, technical field: the utility model relates to a kind of extruding cake, is specifically related to the employed a kind of boss extruding cake of a kind of production extrudate.
Two, background technology: lining and backsight two parts constituted before the existing extruding cake of producing aluminium alloy extrusions mainly contained, because the travel switch of extruder has a minimum control limit, thereby fixed the thinnest standard of pressing surplus thickness, the rate that manufactures a finished product does not just have breakthrough progress.
Three, summary of the invention: it is surplus that the purpose of this utility model just provides a kind of minimizing extruding pressure, improves the extruding cake of yield rate.
A kind of boss extruding of the utility model cake mainly is made of boss, preceding lining and backsight three parts.Described boss is that the end face that serves as a contrast before the extruding cake has increased a columned projection section, and its diameter is less than preceding lining diameter 10mm, thickness 3mm.
Described projection section can be set the size of its area and thickness according to the extruding cake of different size.
The utility model compared with prior art has following characteristics: 1. because projection section has been arranged, improved extruding effectively and manufactured a finished product rate 2. because projection section has been arranged, can change at any time after the damage, reduced economic cost effectively.
Four, description of drawings:
Fig. 1 is a vertical section structure schematic diagram of the present utility model;
Fig. 2 is an enforcement extrusion structure schematic diagram of the present utility model;
Five, the specific embodiment:
Embodiment 1: referring to Fig. 1, Fig. 2, the utility model is made of boss 1, preceding lining 2 and backsight 3 three parts.Pressure ram 4 promotes boss extruding cake and advances, the negative area of the thimble of pressure ram and extruding cake backsight 3 coincide, boss 1 directly contacts with the aluminium bar of high temperature with preceding lining 2, after extrusion process finishes, pressure ram 4 is retracted into the start-up point automatically, boss extruding cake and press the surplus tail end that sticks to mould 5, scissors 6 times generals who has surrendered press under the cotangent, boss 1 can with press surplus the separation.
The utility model has just increased columned projection section at traditional extruding cake front end, makes simple.
