Abstract
The utility model discloses a tool and die for extrusion of seamless aluminum pipe, relating to the mechanical tool and die used for aluminum section extruders. The tool and die for the extrusion of a seamless aluminum pipe is aimed at the existing extrusion of the seamless aluminum pipes which adopts mechanical structures provided with punching systems which have the deficiencies of high equipment investment cost, big tool and die consumption, serious eccentricity, low rate of finished products of products, etc. to provide a tool and die which has a simple structure and can effectively ensure the concentric extrusion of the seamless aluminum pipes. The upper end of an extrusion die 5 is embedded in the inner hole of the lower end of an extrusion cylinder 2, the lower end of an extrusion shaft 1 assembled with the extrusion cylinder 2 is provided with a circular extrusion cushion 3, the upper end of the extrusion cushion 3 is provided with a circular concave groove, and the upper part of a T-shaped extrusion needle is arranged in the circular concave groove.
Description
One, technical field
The utility model relates to mechanic's mould of aluminium section bar ectrusion press, especially a kind of tool and mould of seamless aluminium tubing extruding.
Two, background technology
Aluminum current section bar extruder can only be used for extruded aluminium section, bar, wire rod, but can not push seamless aluminium tubing.Weak points such as push seamless aluminium tubing and now adopt tape punching system mechanics structure, exist equipment investment expense height, tool and mould consumption is big, and is eccentric serious, and the finished product rate is low.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, can effectively guarantee the tool and mould of concentric seamless aluminium tubing extruding.
The technical scheme that the purpose of this utility model adopted is, include extrusion axis and recipient, the upper end of its extrusion die embeds the lower end endoporus of recipient, with the extrusion axis lower end of recipient assembling rounded dummy block is arranged, the upper end of dummy block has the interior device of round concave shape groove that T-shaped extruding pin top is arranged.
When using the utility model, be installed in earlier on the aluminium type extruder, extrusion axis moves down the promotion dummy block and moves downward, and dummy block promotes to push pin again and moves down to the extrusion die nib.
The utlity model has simple and compact for structurely, easy to install, effectively guarantee that the axle center of extruding pin is concentric with the axle center of extrusion die, characteristics such as yield rate height.
Four, description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is that the utility model is adding sectional structure schematic diagram in man-hour.
Among the figure: the excellent 5-extrusion die of the 1-extrusion axis 2-recipient 3-hollow casting of dummy block 4-6-extruding pin 7-seamless aluminium tubing
Five, the specific embodiment
As shown in drawings, the upper end of extrusion die 5 embeds the lower end endoporus of recipient 2, and there is rounded dummy block 3 extrusion axis 1 lower end of assembling with recipient 2, and the upper end of dummy block has the interior device of round concave shape groove that T-shaped extruding pin 6 tops are arranged.The axle 1 that is squeezed promotes the hollow casting rod 4 of dummy block 3 promotions and moves downward, and hollow casting rod 4 is extruded formation seamless aluminium tubing 7 by the gap between extrusion die 5 and the extruding pin 6.
Claims (1)
1, a kind of tool and mould of seamless aluminium tubing extruding, include extrusion axis (1) and recipient (2), it is characterized in that the upper end of extrusion die (5) embeds the lower end endoporus of recipient (2), with extrusion axis (1) lower end of recipient (2) assembling rounded dummy block (3) is arranged, the upper end of dummy block (3) has the interior device of round concave shape groove that T-shaped extruding pin (6) top is arranged.
