Background

The necking machine has the function of reducing the diameter of a pipe fitting object with a certain diameter to be smaller than the original diameter, so that subsequent operations can be carried out, for example, after one end of a steel pipe with the same diameter is reduced, the reduced end can be inserted into other steel pipes which are not reduced in a matched manner, and thus series connection can be realized; or when the heat sink (finished product is also called VC sheet) of the mobile phone is processed, the copper tube as the original part of the heat sink needs to be reduced, and welding is more convenient after the reduction.

Moreover, in the production process of the mobile phone radiating fin, one step is to put a section of copper mesh into the copper pipe, so that after the radiating fin is formed, the copper mesh can play a certain supporting role, and the radiating fin is prevented from being completely attached.

The structure of the existing market, which is common to release the wire or rope outwards (similar to the shape of the copper mesh), mainly comprises a supporting roller, which is used for winding the wire or rope on the supporting roller, then the front pulls the wire or rope, and the rear supporting roller rotates to release the wire or rope. However, because the copper mesh is used periodically, if the structure is used, the copper mesh is easily over-tight sometimes and over-loose sometimes (specifically, if the supporting roller releases more wires or ropes under the action of inertia after one period is finished, the over-loose condition will occur when the next period starts, and after the released excessive part is used, the supporting roller needs to be driven to rotate suddenly subsequently, and the over-tight condition will occur at this moment), and the releasing effect is poor.
