Description

Technical Field

[0001] The utility model relates to a punching die for a hole guard ring for automobiles, belonging to the technical field of punching dies. Background Art

[0002] Grommets, in a broad sense, are a kind of supporting parts for wiring equipment, also known as wire protection sleeves or wire protection rings. As a small supporting part, although small, the wire protection coil plays an important role. There are thousands of types used in production and life. From the appearance, the wire protection coils can be roughly divided into round wire protection coils, round wire protection coils with molds, oval wire protection coils and special-shaped wire protection coils. From the appearance, the wire protection coils can be roughly divided into round wire protection coils, round wire protection coils with molds, oval wire protection coils and special-shaped wire protection coils. Strictly speaking, round wire protection coils with molds can be divided into two categories, intermediate molds and perforated wires. Generally, the round coils on the market refer to double-sided coils, which are the ones without mold holes in the middle. However, in order to meet the use needs in production, higher requirements are placed on coils, namely coils with molds. The advantage of this type of coil is that the mold in the middle can be opened according to the wire size required by the customer, so that there will be no extra gaps at the wire outlet, which is relatively better for dust and water sealing. The oval coil is a relatively large coil, mainly used in the cabinet industry. Due to the diversity of cabinet product models, the oval coil combines the actual needs of the cabinet to form multiple holes side by side to meet the cabinet installation requirements.
