Aluminum alloy anti-crushing extrusion connection equipment and connection method

Abstract

The invention provides aluminum alloy anti-crushing extrusion connection equipment. The aluminum alloy anti-crushing extrusion connection equipment comprises hydraulic presses (2), a controller (3), ahydraulic moving rail (4), a rolling tool (5) and sensors (6), wherein the controller (3) is used for processing a signal of the connection equipment and controlling equipment parts to complete designated functions; the hydraulic presses (2) are used for completing the designated extrusion quantity, input by the controller (3), of an aluminum alloy material (1); the hydraulic moving rail (4) is used for completing transverse moving of the machining rolling tool (5) according to stress and the stress change rates which are received by the controller (3) at different times in the machining process; the rolling tool (5) is used for machining the aluminum alloy material; and the sensors (6) determine acting force borne by the machined material and the change rate of the force by detecting thestress on the rolling tool (5) and the stress change rate. In the process that the equipment achieves extrusion connection, it is sufficiently considered that crushing failure may occur, the spillageof the material in the extrusion process is decreased, and accordingly cost consumption is reduced.

Description

technical field [0001] The invention relates to the field of connecting aluminum alloy materials, in particular to a connecting device used for aluminum alloy materials. Background technique [0002] With the continuous improvement of people's awareness of environmental protection, the continuous improvement of product reliability requirements, and the country's increasing emphasis on environmental pollution issues, the use of aluminum alloy materials in vehicles and related manufacturing fields to reduce vehicle weight and enhance vehicle performance has become a major issue in reducing energy consumption. , energy saving and emission reduction, and important measures to improve safety and reliability. At present, although aluminum alloy materials have begun to be used in many manufacturing industries, due to the influence of the connection cost and connection efficiency of aluminum alloy materials, it is still difficult to widely promote the use of aluminum alloy materials...

AI Technical Summary

Problems solved by technology

[0003] Although the conventional connection technology used for aluminum alloy materials can satisfy the connection between aluminum alloy materials, the connection cost and the versatility of the connection technology have always been unavoidable problems in the connection of aluminum alloy materials.

At present, most aluminum alloy materials are connected by CMT welding, electromagnetic pulse welding and friction stir welding to complete the connection and sealing between aluminum alloy materials. Although the above processes can realize the connection process between aluminum alloy materials, there are still the following problems: 1. At present, most of the joining processes of aluminum alloy materials can meet the welding requirements, but there are disadvantages such as low processing efficiency and high processing costs.

2. At present, some aluminum alloy connection processes have high requirements on the operator in order to ensure the reliability and sealing of the connection, and harmful substances will be produced during the welding process, so it is not only difficult to improve the efficiency but also does not meet the environmental protection requirements.

3. Some of the welding processes used above have different restrictions on the structural form of the parts and the type of welding, which makes it difficult to achieve generalization and popularization of the application range
