AI Technical Summary

Technical Problem

Existing aluminum alloy profile extrusion dies are time-consuming and easily damaged during loading and unloading of blanks, and the fixing method of ordinary dies is not adjustable.

Method used

By setting a sliding pair, a design is adopted for an aluminum alloy profile extrusion die, including an installation component and a fixing component. The position of the linkage plate is adjusted by the slide rail, so that the clamping block clamps both sides of the linkage plate under the action of the compression spring. The cylinder drives the stamping block to press down to form the target profile outline. After stamping is completed, the clamping block releases the linkage plate, and the tension spring pulls the installation block to reset, which facilitates the removal of the finished product and preparation for the next cycle.

Benefits of technology

It improves the processing efficiency of molds, reduces reset time and manual calibration time, ensures accurate alignment of profile processing positions, and avoids secondary adjustments caused by offset.

Abstract

The utility model relates to the technical field of extrusion dies, and discloses an extrusion die for processing aluminum alloy sections, which is characterized in that a fixed part and a fastening part are fixedly arranged on the inner walls of the two sides of the top of a bottom plate respectively, the fastening part is positioned on the outer side of the fixed part, movable frames are mounted at the top ends of the fastening part, and clamping blocks are arranged at the ends, close to each other, of the two movable frames; a sliding groove is formed in the upper surface of the movable frame, the fixing piece is connected to the inner wall of the sliding groove in a sliding mode, the fixing piece is sleeved with a pressure spring, and the pressure spring is located between the movable frame and the bottom plate. Through the arrangement of the clamping blocks and the compression springs, the position of the linkage plate is adjusted through the sliding rails, so that the clamping blocks clamp the two sides of the linkage plate under the action of the compression springs, primary blank fixing is completed, the clamping blocks loosen the linkage plate under the elastic restoring force of the compression springs, meanwhile, the tension springs pull the mounting blocks to reset to the initial position along the sliding rails, and finished products can be taken out conveniently and prepared for the next cycle; and the machining efficiency of the die is improved.
