A cleaning device for extrusion molding of aluminum alloy

Abstract

The invention discloses a cleaning device for aluminum alloy extrusion forming. The cleaning device comprises a workbench, an ejecting mechanism, a forming mechanism, a mold base, a discharging mechanism and an extruding barrel cleaning mechanism, wherein a through groove is longitudinally formed in the middle of the workbench, and sliding rails are arranged on the upper surface of the workbench along both sides of the through groove; the forming mechanism is arranged above the sliding rails, and a lifting base which is used for bearing the forming mechanism and can rotate is arranged below the center of the bottom of the forming mechanism; the ejecting mechanism is arranged on one end of the workbench and comprises an extruding oil cylinder and a hydraulic ejecting shaft which is arrangedon the front end of the extruding oil cylinder and faces towards the forming mechanism; the mold base is arranged on the other end of the workbench; the discharging mechanism is arranged on the otherend of the mold base; and the extruding barrel cleaning mechanism is arranged on one side of the forming mechanism. The cleaning device has an adaptive extruding barrel cleaning function, and a freeswitching mode of backward and forward extrusion during operation of aluminum alloy profile forming can be realized.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy extrusion processing, in particular to a cleaning device for aluminum alloy extrusion molding. 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 compress...

AI Technical Summary

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
