no. 1 approach

[0046] Figure 1-8 A first embodiment of the extruder of the present invention (a rod-slide extruder) is shown diagrammatically. figure 1 It is a side view showing the schematic structure of the extrusion machine of 1st Embodiment. figure 2is viewed from above figure 1 top view of the device. image 3 yes figure 1 A partial enlargement of the . Figure 4 From figure 1 A cross-sectional view viewed along line A-A. Figure 5 From figure 1 The side view of the BB line observation. Figure 6 is a rear view viewed from the rear.

[0047] The extruder of the present invention is provided with an electric extrusion drive device that converts rotary motion into linear motion. The extrusion machine of the present invention pushes the extrusion rod by the extrusion force generated by the electric extrusion driving device, pressurizes the billet usually at about 400-500°C, and extrudes a product of a predetermined shape through a die.

[0048] First refer to figure 1 and 2 ,...

no. 2 approach

[0078] use Figures 9 to 11 A second embodiment will be described. In the second embodiment, a case will be described in which there are four press drive devices 52 .

[0079] In addition to the two extrusion drive devices of the electric extrusion machine, two additional extrusion drive devices (four in total) were arranged and connected in series by two. The fixed pressing plate 2 and the fixed pressing plate 21 are composed of Figure 11 Four connecting rods 58 are shown connected. exist Figure 11 Among them, there are four connecting rods 58, but the number can be more.

[0080] In addition, pressing one end of the moving member 15 ( Figure 9 The left side) is the crosshead 7, the other end ( Figure 9 The right side) is fixed to the moving pulley 48 of extrusion driving device 53. The moving pulley 41 of the pressing driving device 52 is connected to the middle of the pressing moving member 15 . In addition, in the extrusion machine of this embodiment, the extru...

Abstract

An electric extrusion press in which an extrusion stem (13) is pressed with an extrusion force produced by an electric drive apparatus, thereby applying pressure to a billet (8) and extrusion-molding a predetermined article through a die (20), wherein the electric drive apparatus comprises one or a plurality of wire drums (31) rotatably provided, and a main motor (36) for electric extrusion rotates the wire drums to wind up wires (32) so as to apply a thrusting force in the extrusion direction to a moving pulley (41) and drive a crosshead (7) and the extrusion stem forward via an extrusion movement part (15).

Description

technical field [0001] The present invention relates to an extruding machine, in particular to an extruding device for extruding metal materials such as aluminum or its alloy through a die, and to an electric extruding machine in which the driving of the extruding force is electric. Background technique [0002] Extrusion machines are used to extrude and form metal products such as aluminum frames. In a conventional extruder, a billet as a material is charged into a fixed extrusion cylinder. It is extruded using a squeeze rod driven by a plunger cylinder (hydraulic cylinder). The billet is formed into a predetermined cross-sectional shape by passing the billet through a die attached to the outlet of the extrusion cylinder. The billet loaded in such a forming machine is supplied from a billet feeder. The billet loader grabs the billets sent one by one from the billet carrier arranged on the side of the molding machine, and transfers them to the billet charging port of the ...
