Abstract

The invention discloses an extruding forming device used for aluminum alloy profile. The extruding forming device used for the aluminum alloy profile comprises a workbench, an eject-out mechanism, a forming mechanism, a mold machine base and a discharging mechanism; the middle portion of the workbench is provided with a through groove in the longitudinal direction; the upper surface of the workbench is provided with slide rails along the two sides of the through groove; the forming mechanism is arranged above the slide rails; a rotatable lifting base used for bearing the forming mechanism is arranged below the bottom center of the forming mechanism; the eject-out mechanism is arranged at one end of the workbench, and comprises an extruding oil cylinder and a hydraulic ejecting shaft arranged at the front end of the extruding oil cylinder and facing the forming mechanism; the other end of the workbench is provided with the mold machine base; the mold machine base comprises a base arranged above the workbench; stand columns are arranged on the two sides of the base, and a pressure bearing top plate is arranged between the stand columns and above the base; and the discharging mechanism is arranged at the other end of the mold machine base. The extruding forming device used for the aluminum alloy profile can achieve that backward and forward extruding manners can be freely switchedin forming and machining operation of the aluminum alloy profile, and the functions of fast mold plate disassembling and assembling, self-adaption cleaning of an extruding barrel, efficient and stable lubricating oil feeding, and temperature control are achieved.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy processing, in particular to an extrusion molding device for aluminum alloy profiles. Background technique [0002] Aluminum extrusion molding is to apply strong pressure to the metal billet placed in the mold cavity (or extrusion barrel), forcing the metal billet to produce directional plastic deformation and extrude from the die hole of the extrusion die to obtain the required section Plastic processing method of parts or semi-finished products with shape, size and certain mechanical properties. [0003] Conventional aluminum profile extrusion methods are divided into forward extrusion and reverse extrusion. The difference between the two mainly lies in whether the extrusion cylinder moves during the extrusion process; the process characteristics of aluminum extrusion include: During the process, the extruded metal can obtain a more intense and uniform three-dimensional compressive stres...

Problems solved by technology

[0004] Similarly, the aluminum extrusion process also has many disadvantages: first, due to the flexibility of the aluminum extrusion process, it is necessary to quickly switch between different extrusion methods for different extrusion processing requirements, and the existing forward extrusion processing equipment, Only a small part can be switched to the reverse extrusion processing method, but this is only a temporary replacement, which cannot be processed for a long time and the processing quality has also declined; It also takes a lot of time to assemble and replace parts, which obviously affects the processing and production efficiency; secondly, the replacement and disassembly efficiency of the forming template, which is indispensable in the process of aluminum extrusion processing, is also a key link that affects the processing efficiency; considering the life The problem is that the formwork cannot be used for a long time, and for different processing and forming requirements, it is also necessary to quickly debug and replace the formwork; secondly, the defects of bubbles and peeling of extruded aluminum profiles often occur because the extrusion cylinder or the extrusion pad is too large. Dirty, the debris and waste slag in it are not cleaned out in time, and the barrel is not cleaned up when the alloy is replaced; when the temperature in the extrusion barrel and the temperature of the extrusion ingot are too high, bubbles and peeling on the surface of the profile may also occur
