Description

Technical Field

[0001] The utility model relates to the technical field of shaft center drawing, in particular to a shaft center drawing device. Background Art

[0002] The structure of the magnetic roller component used in printers and copiers is composed of a three-pronged or multi-pronged tube body and shaft cores at both ends. The shaft core is usually made of stainless steel, and the three-pronged or multi-pronged tube body is usually made of aluminum alloy. The magnetic roller component usually uses hydraulic equipment to press the shaft core into the end of the aluminum alloy tube body so that it is fastened to the two ends of the aluminum alloy tube, which plays a supporting role when the magnetic roller component rotates in the printer copier. Defective products produced during the production process are usually returned to the factory for recycling. Before recycling, the stainless steel part of the magnetic roller component and the aluminum alloy three-pronged or multi-pronged tube body need to be sorted and recycled. During sorting and recycling, the pressed stainless steel shaft core needs to be pulled out of the three-pronged or multi-pronged tube body for material sorting.

[0003] The defects of the existing technology are as follows: manual tapping of the shaft core causes it to deform and fall off. It is labor-intensive, time-consuming and inefficient. Manual tapping of the shaft core end can easily break the shaft core into two sections, and stainless steel materials can easily break in the three-pronged or multi-pronged tube body. Different materials are mixed during recycling, resulting in changes in the content of metal elements in the recycled aluminum, affecting the quality and performance of the material products.
