Description

Technical Field

[0002] Open-type fixed-table presses are a common type of metal processing equipment, widely used in various pressing, punching, bending and other processing operations.

[0003] Presses play an important role in modern manufacturing industries. When the press slide reaches the bottom stop, the blank can be extruded and shaped by the mold fixed to the bottom of the slide. The extruded product will stick to the mold. Especially during hot stamping, the blank is more easily shaped after being heated, and the product will stick to the mold.

[0004] After the blank is formed, an ejector device is needed to eject the material from the mold. Generally, this is done by a slider driving an ejector bar. The slider directly drives the ejector device, which has a simple structure and requires no additional power. When ejecting material, the ejector beam is stopped by the ejector bar, which pushes the mold ejector pin out of the slider to achieve product demolding. Common ejector bars are columns of fixed length. When producing different products, different lengths of ejector bars need to be replaced due to different mold opening strokes, which increases production costs. Different molds also require different lengths of ejector bars to be replaced during assembly, which is time-consuming and affects production efficiency.
