Description

TECHNICAL FIELD

[0001] The utility model relates to aluminium alloy section production technical field, concretely is a kind of punching device for aluminium alloy section production. BACKGROUND

[0002] Aluminium alloy section refers to the aluminium alloy material with specific cross-sectional shape made by extrusion, rolling and other processes. This material is widely used in construction, automobile, aerospace, electronic equipment and other fields due to its lightweight, high strength, corrosion resistance and other characteristics.

[0003] In order to fix and connect other components (such as bolts, nuts, etc.), or to allow wires or pipes to pass through, aluminium alloy sections are often punched according to actual needs when leaving the factory. Some design specifications or standards may require a specific number of holes to ensure compliance with specific installation or performance requirements. For example, when three equally spaced holes need to be punched in an aluminium alloy section, workers will choose a punching device equipped with three drilling machines. This allows three holes to be punched simultaneously, significantly improving production efficiency compared to a punching device with only one drilling machine. However, the spacing between the three drilling machines on the existing punching device is not adjustable. When larger spaced holes are needed, the punching device needs to be re-customized to meet the punching needs, which is inconvenient for workers and increases production costs to some extent. Therefore, we propose a punching device for aluminium alloy section production. SUMMARY

[0024] Working principle: first, place the aluminum alloy profile to be punched between the upper end of the bottom plate 1 and the front end of the clamping plate 9, then connect the two electric push rods 7 with the external power supply, the telescopic shafts of the electric push rods 7 will move backward together and drive the clamping plate 8 to move backward, thereby clamping and fixing the aluminum alloy profile between the bottom plate 1, the clamping plate 8 and the clamping plate 9, then connect the drilling machine 12 and the two drilling machines 6 with the external power supply in turn, then the drill bits of the drilling machine 12 and the two drilling machines 6 can rotate at high speed (this is a known prior art and will not be described in detail), finally, connect the electric push rod 1 on the L-shaped support frame 2 with the external power supply, then the telescopic shaft of the electric push rod 1 will move downward and drive the rectangular shell 4 to move downward, the rectangular shell 4 can drive the drilling machine 12 and the two drilling machines 6 to move downward, thereby completing the punching of the aluminum alloy profile, and similarly, the same operation can be performed on the other aluminum alloy profiles in the batch.
