Description

Technical Field

[0001] The utility model relates to the technical field of trimming devices, and more specifically, it relates to a trimming device for automotive aluminum alloy brackets. Background Art

[0002] The application of aluminum alloy brackets in the automotive field is one of the important directions for automotive lightweighting. Due to its light weight, high strength, easy processing, and good corrosion resistance, aluminum alloy is increasingly widely used in automobiles. Aluminum alloy brackets are mainly applied to key parts such as engines, chassis systems, wheels, transmission systems, thermal management systems, and body structural parts in automobiles. Especially for aluminum alloy subframes, as important structural parts connecting suspension devices and the body, using aluminum alloy materials can significantly reduce the weight of automobiles and improve energy efficiency.

[0003] Currently, for aluminum alloy bracket trimming devices on the market, the aluminum alloy brackets are usually stably placed on the workbench and fixed by a clamping mechanism to ensure stability during the processing. These devices generally adopt hydraulic or electric drive methods to control the blade to accurately cut off the burrs on the edge of the aluminum alloy bracket. The metal debris and burrs generated during the cutting process will be effectively collected and processed by the collection system equipped with the trimming device, thereby keeping the working environment clean and improving production efficiency.

[0004] When cutting aluminum alloy brackets, since the trimming devices on the market cannot meet the cutting requirements of this aluminum alloy bracket, burrs will appear during the cutting of the aluminum alloy bracket. And due to the special shape of the aluminum alloy, it is difficult for the tool head to withdraw after cutting, which causes damage to the cut workpiece. For the waste generated during the cutting process, the general collection efficiency is relatively low and it is difficult to meet the requirements of rapid processing. Summary of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a trimming device for automotive aluminum alloy brackets.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A trimming device for an automotive aluminum alloy bracket, including a fixed die unit, above which a trimming unit is provided. The fixed die unit includes a fixed die support seat, on both sides of which are respectively fixedly connected with material receiving grooves. Above the fixed die support seat is installed a fixed die seat. At the positions of the two sides of the I-shaped part of the fixed die seat are installed limiting rods, and at the four corner positions of the fixed die seat are provided guiding pins; the trimming unit includes a trimming bracket, the shape of which is arranged in a double-layer rectangle. In the middle of the rectangle of the trimming bracket are provided two rectangular plates. At the four corner positions of the trimming bracket are evenly provided connecting columns.
