Welding equipment for radial cold-state connection of multiple strands of wire bodies and control method

Abstract

The invention relates to the technical field of ultrasonic welding, in particular to welding equipment for radial cold-state connection of multiple strands of wire bodies. The limiting block is movably arranged in the vertical direction; the first extrusion block is connected with the first horizontal power to provide horizontal extrusion force for the first area of the wire body; the second extrusion block is connected with the second horizontal power and is used for closing or opening the top of a groove body defined by the ultrasonic welding head, the limiting block and the first extrusion block through horizontal movement; and vertical power is further included, and the second extrusion block is extruded downwards. Through the arrangement of the first extrusion block and the second extrusion block, the multiple strands of wire bodies can be extruded multiple times in the extrusion process, the multiple extrusion mode can enable the wire bodies to obtain the time for rearrangement, and in the extrusion process, gaps between the wire bodies tend to be uniform and compact through position adjustment, so that the wire bodies are more uniform and compact. The invention further discloses a control method of the welding equipment.

Description

technical field [0001] The invention relates to the technical field of ultrasonic welding, in particular to a welding device and a control method for radial cold-state connection of multi-strand wire bodies. Background technique [0002] Ultrasonic welding is to transfer high-frequency vibration energy to the joint position of the workpiece to be welded. In this area, the vibration energy makes the surfaces of the workpiece to be welded rub against each other to form intermolecular interlacing and fusion, so as to achieve fast, energy-saving, non-spark and close Cold worked welds. [0003] At present, the above-mentioned welding method can achieve a stable connection for the two structures to be connected, but for the connection of multi-strand wire bodies, welding defects are extremely prone to occur due to the large gap area between each wire body and the different gap forms , thus seriously affecting the connection strength of multi-strand wires; at present, the above pr...

[0003] At present, the above-mentioned welding method can achieve a stable connection for the two structures to be connected, but for the connection of multi-strand wire bodies, welding defects are extremely prone to occur due to the large gap area between each wire body and the different gap forms , thus seriously affecting the connection strength of multi-strand wires; at present, the above problems can be alleviated to a certain extent by applying pressure to the wires, but due to the inhomogeneity of the gaps between the strands, it is difficult to pass a single The uniform arrangement of each strand body is achieved by repeated extrusion, so that the connection defects between each strand body are still difficult to overcome
