Description

Technical Field

[0001] The invention relates to a vehicle door connecting piece processing equipment, in particular to a vehicle door connecting piece continuous extrusion die. Background Art

[0002] The door connector generally includes an L-shaped connecting plate 111, and the two long sides and one end of the connecting plate 1 are provided with a panel 112. The connecting plate 111 near the end panel 112 has a hole 113, such as Figure 1 As shown. When processing workshop connectors, it is necessary to process the holes.
