Embodiment 1

[0037] In a typical implementation of the present invention, please refer to Figure 4 , this embodiment discloses an extrusion die for realizing a two-way extrusion forming process, including a punch 8 and a die 7, and the punch 8 and the die 7 are matched;

[0038] The die 7 has an opening as a discharge port, the opening is provided with a working belt, and the shape of the opening is consistent with the cross-sectional shape of the outer surface of the hollow profile product.

[0039] The punch 8 has two inlets and one outlet, and the two inlets are respectively located on the first side and the second side of the punch 8, and the first side and the second side of the punch 8 are the sides of the punch 8. On two opposite sides, the outlet is located on the third side, the third side is located between the first side and the second side, the axes of the two inlets are on the same straight line, and are perpendicular to the axis of the outlet.

[0040] It can be understood ...

Embodiment 2

[0045] In a typical embodiment of the present invention, such as figure 1 As shown, this embodiment discloses an extrusion device for realizing a two-way extrusion forming process, including a center beam 1 of an extrusion machine, an extrusion cylinder beam 2, an extrusion cylinder beam 3, a connecting rod 4, a first extrusion cylinder 5. The second extrusion barrel 6 and the hydraulic push-pull rod 9 also include the bidirectional extrusion die disclosed in Embodiment 1. in such as figure 1 In the structure shown, the central beam 1 of the extruder is located at the center, and there is an extrusion cylinder beam and an extrusion cylinder on its left and right sides, and the central beam 1 of the extruder and the extrusion cylinders on its left and right sides The crossbeam is connected by connecting rod 4.

[0046] That is, the two sides of the central beam 1 of the extruder are respectively connected to the beam 2 of the first extrusion cylinder 5 and the beam 3 of the s...

Embodiment 3

[0059] In a typical implementation of the present invention, embodiment 3 provides an extrusion method for realizing a bidirectional extrusion forming process, using the extrusion device disclosed in embodiment 2 for realizing a bidirectional extrusion forming process, Include the following steps:

[0060] Before the two-way extrusion, the die 7 and the punch 8 are connected together through the connecting and positioning parts on them, and they are moved from the die entrance of the center beam 1 of the extrusion machine along the chute 3-005 through the hydraulic push-pull rod 9 Push. The hydraulic push-pull rod 9 exerts a certain pressure on the extrusion die so that the die 7 and the punch 8 are locked to each other;

[0061] Put the two extrusion bars into the first extrusion cylinder 5 and the second extrusion cylinder 6 respectively through the feeding mechanism, and then make the first extrusion cylinder 5 beam 2 and the second extrusion cylinder 5 through a certain h...

Abstract

The invention discloses an extrusion die, a device and a method for realizing a bidirectional extrusion forming process, and relates to the field of dies. The device comprises an extruder central cross beam, a first extrusion cylinder, a second extrusion cylinder, a push-pull rod and the extrusion die for realizing the bidirectional extrusion forming process, the push-pull rod is fixedly connectedwith a male die, a first extrusion cylinder inlet and a second extrusion cylinder inlet are formed in the first side face and the second side face of the extrusion machine center cross beam respectively, after the extrusion die for achieving the bidirectional extrusion forming technology enters a die inlet and a die outlet, a first extrusion cylinder penetrates through an extrusion cylinder inletof the first extrusion cylinder and makes contact with the first side face of the male die, and the second extrusion cylinder penetrates through an extrusion cylinder inlet of the second extrusion cylinder and makes contact with the second side face of the male die. According to the extrusion die, the device and the method for realizing the bidirectional extrusion forming process, the problems ofdie disassembly and assembly, feeding, bidirectional extrusion action, pressing residue shearing and the like in the current bidirectional extrusion process can be solved.

Description

technical field [0001] The invention relates to the field of molds, in particular to an extrusion mold, a device and a method for realizing a bidirectional extrusion forming process. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The bidirectional extrusion process refers to a new type of extrusion forming process in which pressure is applied to the material from two directions, so that a velocity gradient is generated inside the material to drive the overall bending of the material, thereby obtaining an extruded product bent along the length direction. Metal and non-metal profiles that are curved along their length and have variable curvature can be manufactured using this process. The main advantages of using the bidirectional extrusion process to manufacture curved profiles include: (1) It can reduce or even eliminate the common problems of be...
