Problems solved by technology

The vertical metal extrusion machine has the following problems: 1. It cannot complete the perforation, and needs to be equipped with additional perforation equipment, and the integration is insufficient; 2. It can only complete the forward extrusion process; 3. This form of extrusion machine requires very high requirements. Deep pits, or the foundation of the extruder is raised very high, and the civil engineering is large; 4. The anti-eccentric load capacity is weak, and the guiding accuracy is insufficient when extruding special-shaped parts

Embodiment 1

[0044] Embodiment 1: Forward extrusion process of metal pipe fittings

[0045] As one of the preferred solutions of the present invention, refer to Figure 10 . A feasible mold assembly method is as follows: the extrusion mold base 61, the extrusion mold sleeve 62 and the extrusion cylinder 63 are sequentially fixed at the bottom of the upper backing plate 28, and the relative position between the extrusion cylinder and the extrusion mold sleeve is passed through the clamping cylinder Or the bolt remains unchanged; the extrusion shaft 64 is mounted on the mobile workbench 3, the extrusion pad 65 is mounted on the extrusion shaft 64 through the locking bolt, and the mandrel 66 is inserted in the center of the extrusion shaft 64 and the extrusion pad 65 , and set with the concentric center of the squeeze pad 65.

[0046] In the billet loading process, the mobile worktable 3 is moved out, and the billet that has completed the piercing process is placed on the mandrel 66. The pi...

Embodiment 2

[0047] Embodiment 2: Back-extrusion process of metal bar.

[0048] As one of the preferred solutions of the present invention, refer to Figure 11 . A feasible mold assembly method is as follows: the back extrusion die base 67 is fixed on the upper backing plate 28 by bolts, the back extrusion shaft 68 is fixed on the back extrusion die base 67 by bolts; the extrusion cylinder 63 is fixed by bolts or Other feasible connection modes are installed on the mobile workbench 3 .

[0049] In the billet loading process, the mobile table 3 is moved out, and the billet is placed in the extrusion cylinder 63 . When the extrusion process starts, the bearing frame 2 moves down, driving the extrusion shaft mold base 67 and the counter-extrusion shaft 68 to go down, and the billet is extruded from the gap between the extrusion cylinder 63 and the counter-extrusion shaft 68 . The carrying frame 2 goes up, the anti-extrusion shaft withdraws, and the inner wall of the extrusion cylinder 63 c...

Embodiment 3

[0050] Embodiment 3: metal blank making perforation combined extrusion process

[0051] As one of the preferred solutions of the present invention, refer to Figure 12 . A feasible mold assembly method is as follows: the upsetting rod 69, the piercing needle 610, the extrusion pad 65 and the mandrel 66 are respectively loaded on the three stations of the mobile workbench. The extrusion barrel 63 is mounted on the extrusion die base 61 . The extrusion die sleeve 62 is pull-out type and is located between the extrusion cylinder and the extrusion die holder. The extrusion die sleeve can be adjusted according to the technological requirements, and the extrusion die sleeve can be moved by conventional techniques.

[0052] First, put the billet on the upsetting rod, which is at the working station (that is, the mobile worktable station under the bearing frame), and the bearing frame moves down, driving the extrusion cylinder to go down, at this time, the extrusion die sleeve It i...

Abstract

The invention discloses a multifunctional vertical metal extruding machine and belongs to the field of pressure machining forming equipment for metals. The machine comprises a main cylinder, a bearing rack, a moving workbench, a supporting seat and a guiding unit; the bearing rack comprises four vertical stand column beams arranged symmetrically as well as an upper semi-circular beam and a lower semi-circular beam which are located at two ends of each vertical stand column beam; a taking port is further formed in the upper semi-circular beam; the main cylinder is close to lower parts of the four vertical stand column beams and comprises a main cylinder block and a main cylinder plunger located inside the main cylinder block; the main cylinder block is fixed on the ground through the supporting seat located around the vertical stand column beams; the bearing rack is driven the main cylinder plunger to move vertically; guidance is realized through the guiding unit; and the moving workbench is located at the top of the supporting seat and moves horizontally on the supporting seat. Operation conditions of the vertical extruding machine are improved with the discharging method adopted by the extruding machine, the construction cost is reduced, and multiple technologies can be completed on one machine.

Description

technical field [0001] The invention belongs to the field of metal pressure processing and forming equipment, and in particular relates to a multifunctional vertical metal extrusion machine. Background technique [0002] Metal extrusion processing belongs to the category of pressure processing. It adopts the method of applying external force to make the metal subjected to three-dimensional compressive stress produce plastic deformation and be extruded from the set hole or gap. The metal extruder is the equipment that completes the extrusion process. According to the position of the working axis, it can be divided into a vertical extruder and a horizontal extruder. Due to the effect of gravity, the horizontal extrusion machine has the problems of uneven wear of the plunger to the seal and uneven wear of the moving beam to the guide rail. In addition, the gravity on the billet in the radial direction will cause easy wear of the equipment and easy eccentricity of the product. ...
