Abstract

The utility model discloses a metal extrusion die. The metal extrusion die is composed of a pressing plate, a piece discharging device, a piece discharging plate, a base plate, a terrace die, a concave die, a combined concave die ring, a combined concave die outer ring, a crescent plate, an ejector, a cushion block and a base plate. The module adopts a universal die frame, a changing terrace die and a combined concave die part; different extrusion pieces can be extruded, and meanwhile, different metalware can be subjected to direct extrusion, reverse extrusion and combined extrusion, the propagation of pressure is good, the movement is reliable, the metal extrusion die is safe and environment-friendly, the structure of the die is simple, and the metal extrusion die is suitable for high speed punching formation of metal stamping pieces.

Description

A kind of metal extrusion die tool

Technical field

The present invention relates to cold punching die, is a kind of metal extrusion die tool.

Background technology

Cold extrusion die must adapt to cold-extruding metal deformation characteristics and powerful cold-extruded pressure to the mould requirement, and the shape of working portion of die, size and surface should be conducive to plastic deformation of metal, are conducive to reduce extruding force; Mould should have enough strength and stiffness, and good guider is arranged; The mold materials and the Technology for Heating Processing that are fit to the cold extrusion requirement should be selected for use, consumable accessory dismounting, replacing, easy for installation and versatility should be noted on the structure.The version of cold extrusion die is more, by mode forward extrusion mould, indirect-extrusion mould, Compound Extrusion mould and other extrusion die are arranged, by versatility, special-purpose cold extruding die and general cold extruding die are arranged, by adjusting, having and can debug extrusion die and general cold extruding die.Though above-mentioned cold-extruded mould adapts to cold-extruding metal deformation characteristics and powerful cold-extruded pressure to the mould requirement.But the shape of working portion of die, size are unfavorable for metal plastic deformation, are unfavorable for reducing extruding force, and mould does not possess enough strength and stiffness, simultaneously in dismounting, replacing, extremely inconvenient when installing.In order to overcome the deficiency of above-mentioned mold mechanism, I am according to line design and manufacturing experience for many years, and the spy provides following a kind of mold mechanism to solve this difficult problem.

Summary of the invention

The present invention provides a kind of metal extrusion die tool, and it is achieved in that this mould adopts universal die set, changes punch, combined die part, can push different extrusions, also can carry out forward extrusion, Compound Extrusion.The punch-die axiality can be adjusted, and namely adjusts the position of die by screw and crescent plate, to guarantee the axiality of punch-die.Die displacement in the time of simultaneously can preventing from pushing.Die is pre-seat power combined die structure, and is big with extrusion pressure.For the ferrous metal extruding, its extrusion may bind round on punch, therefore is provided with shedder, and it is in order to reduce punch length, to gain in strength and hardness and abrasion resistance that the inloading part plate is made bending.Because Extrusion Force in Ferrous Metal Extrusion is big, so punch upper end and ejector lower end are designed to tapering, with the expansion bearing area, and the thickening backing plate.A kind of metal extrusion die tool has solved shape, the size of working portion of die, is unfavorable for metal plastic deformation, is unfavorable for reducing the problem of extruding force.Solved mould and do not possessed enough strength and stiffness, simultaneously the problem of inconvenience when dismounting, replacing, installation.A kind of metal extrusion die tool is characterized in that: pressing plate (1) is communicated with combination groove outer ring (8) and crescent plate (9), inloading part device (2) is installed in the step-shaped hole of inloading part plate (3), punch (5) is with after inloading part device (2) glade plane space cooperates, compress with backing plate (4) and be communicated with at the big end of punch (5) then, die (6) is installed in the combined die outer ring (7), backing-out punch (10) and cushion block (11) glade plane space are communicated with die (6) after cooperating again, the big end of backing-out punch (10) compresses with backing plate (12) and is fastening, is communicated with the liftout attachment of forcing press then.

Description of drawings

The present invention is further described below in conjunction with accompanying drawing:

Sectional side elevation when Fig. 1 is the extruding of a kind of metal extrusion die tool matched moulds.

Fig. 2 is the vertical view of a kind of metal extrusion die tool ranking.

Numeral number is represented respectively among the figure:

1---pressing plate 2---inloading part device 3---inloading part plate

4---backing plate 5---punch 6---dies

7---combined die circle 8---combined die outer ring 9---crescent plates

10---backing-out punch 11---cushion block 12---backing plates

The specific embodiment:

Be a kind of metal extrusion die tool shown in the figure, mould extruding ferrous metal hollow object mould, mould adopts universal die set, changes punch, and the combined die part can the different extrusions of backward extrusion, can also carry out forward extrusion, Compound Extrusion.The punch-die axiality can be adjusted, by the position of screw and crescent plate (9) adjustment die (6), to guarantee the axiality of punch-die.Simultaneously can rely on crescent plate (9) and pressing plate (1) to compress the location, in case extrusion process die (6) displacement.Die (6) is prestressing combination die structure simultaneously, and it is big to bear extrusion pressure.For the ferrous metal backward extrusion, its extrusion may bind round on punch, therefore is provided with shedder, and it is in order to reduce punch length that inloading part plate (3) is made bending.Big because of Extrusion Force in Ferrous Metal Extrusion simultaneously, so punch upper end and ejector (10) lower end are designed to tapering, to enlarge bearing area.

Claims (1)

1. a metal extrusion die tool is characterized in that: pressing plate (1) is communicated with combination groove outer ring (8) and crescent plate (9), inloading part device (2) is installed in the step-shaped hole of inloading part plate (3), punch (5) is with after inloading part device (2) glade plane space cooperates, compress with backing plate (4) and be communicated with at the big end of punch (5) then, die (6) is installed in the combined die outer ring (7), backing-out punch (10) and cushion block (11) glade plane space are communicated with die (6) after cooperating again, the big end of backing-out punch (10) compresses with backing plate (12) and is fastening, is communicated with the liftout attachment of forcing press then.
