Description

Technical Field

[0001] The utility model relates to the technical field of gold wire die structures, and particularly relates to a gold wire bonding die. Background Art

[0002] Gold wire is the general term for various metal wire materials. A wire drawing die usually refers to various dies for drawing metal wires, and there are also wire drawing dies for drawing optical fibers. There is a hole with a certain shape in the center of all wire drawing dies, such as circular, square, octagonal or other special shapes. When the metal is drawn through the die hole, its size becomes smaller and even its shape changes. When drawing soft metals (such as gold and silver), a steel die is sufficient, and there can be multiple holes with different hole diameters on the steel die. Existing wire drawing dies generally consist of an inner die and an outer die. In order to ensure the reliability of the connection between the inner die and the outer die, the connection structure is relatively complex, resulting in a high die opening cost. At the same time, it is difficult to ensure the installation accuracy between the inner die and the outer die. In view of the above problems, this application provides a solution. Content of the Utility Model

[0003] The purpose of the utility model is to provide a gold wire bonding die.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions:

[0005] A gold wire bonding die includes an outer die and an inner die. An installation groove for installing the inner die is provided on the outer die. A die hole is provided in the middle of the inner die. The wire outlet of the outer die is arranged at the other end opposite to the installation groove. A plurality of slots are provided on the side wall of the installation groove. A plurality of chutes are provided at one end of the inner die close to the entrance of the installation groove. The number and position of the chutes and the slots are correspondingly arranged. The inner die is installed in the installation groove of the outer die. One end of a key block is inserted into the slot along the chute, and the other end of the key block is located in the chute, fixing the inner die in the installation groove of the outer die.

[0006] Furthermore, a deformation groove is provided at one end of the key block inserted into the chute, and a raised block is provided at one end of the key block located in the chute. The deformation groove can ensure being clamped into the slot and prevent the key block from falling off from the deformation groove.

[0007] Furthermore, a chamfer is provided at the entrance position of the slot, which is convenient for the key block to be inserted into the slot.

[0008] In summary, the utility model has the following beneficial effects: The utility model quickly installs and fixes the inner die and the outer die through the assembly of the key block and the slot with a special structure. The installation structure is simple and reliable. At the same time, when disassembling, the key block can be pulled out through the raised block on the key block, which is convenient for replacing the inner die. Description of the Drawings
