Description

Technical Field

[0001] The invention relates to the technical field of extrusion molding, and in particular to an extrusion molding device for aluminum alloy door and window profiles. Background Art

[0002] Aluminum alloy door and window profile extrusion forming technology is an advanced metal processing technology, which is widely used in the construction industry, especially in the manufacture of high-end doors and windows. This technology uses high pressure to extrude aluminum alloy billets into aluminum profiles with the required cross-sectional shape through an extruder. The specific processing process is to first cut the raw material into aluminum bars of the required length through a cutting mechanism, and then push the aluminum bars to the feeding mechanism. The feeding mechanism drives the aluminum bars to move to the extrusion device position, and then the extruder drives the extrusion column to move down coaxially with the aluminum bar, and then the extruder moves through the extrusion column to push the aluminum bar to the forming mechanism, and the corresponding shape of the mold in the forming mechanism forms the aluminum bar pushed in.

[0003] However, the following problems currently exist in the process of conveying and moving extrusion of aluminum bars: when the cut aluminum bars are moved to the extruder position, the rolling range is limited only by the limit plate without an additional fixing mechanism, which makes the aluminum bars easy to roll during movement, causing damage to the surface of the aluminum bars, thereby affecting the quality of profile processing; secondly, in the process of pushing the aluminum bars into the forming mechanism, there is no additional device to guide the aluminum bars, which makes it difficult for the aluminum bars to be pushed into the forming mechanism, affecting the smoothness of the aluminum profile processing and easily causing damage to the aluminum bars and equipment.

The fixed plate 430 will first contact the driving plate 71 through the pushing plate 72 to push the driving plate 71 to move away from the No. 2 compression spring 333. The driving plate 71 will drive the corresponding No. 2 connecting plate 332 to move upward through the shaft seat and the connecting rod 70, and the No. 2 connecting plate 332 will drive the insertion rod 331 to penetrate the corresponding circular hole and the through hole 330 to further improve the stability of the support plate 31 and the corresponding slide plate 320.

[0048] Then the fixing plate 430 contacts with the receiving plate 10 to limit the further movement of the fixing plate 430. After that, as the seat body 40 moves, the compression spring 431 will be compressed to continue to move, and the extrusion column 42 will contact with the aluminum rod to push the aluminum rod into the forming mechanism 2 for forming processing. After the processing is completed, the solenoid valve on the external No. 2 conveying pipe controls the No. 2 hydraulic cylinder 441 to pull the seat body 40 away from the forming mechanism 2, and the push plate 435 moves forward away from the stop plate 436. The connecting plate 323 moves toward the corresponding support seat 326 under the action of the No. 1 compression spring 322, and drives the The corresponding clamping block 324 moves to reset, and then the lifting plate 434 moves away from the column 63.
