Steel Bar Cold Pressing Needle Extrusion Parameters

Rebar crimp contact extrusion is a commonly used metal processing method used to strengthen the connection and fixation of rebars. This article will introduce the key parameters of rebar crimp contact pin extrusion and the impact of these parameters on processing quality and efficiency.

1. Pressure parameters
The pressure of rebar contact socket crimp extrusion is an important parameter, which directly affects the strength of the processed rebar connection. Excessive pressure will cause the rebar to deform or break, and too little pressure will not achieve the ideal connection effect. Therefore, when performing crimp contact female extrusion, it is necessary to determine the appropriate pressure according to the diameter and material strength of the rebar.

2. Temperature parameters
Temperature also has an important influence on rebar crimp contact male extrusion. Generally, crimp socket contact extrusion is carried out at room temperature, but in special cases, the rebar needs to be preheated or cooled. Preheating can improve the plasticity of the rebar, while cooling can increase the strength of the connection. Different rebar materials and specifications require targeted determination of appropriate temperature parameters.

3. Sleeve size parameters
The sleeve size is another important parameter of female crimp contact extrusion. The size of the sleeve needs to match the diameter of the steel bar to ensure that the sleeve can completely wrap the steel bar and the connection is firm. The length of the sleeve also needs to be selected according to actual needs. Generally, the length of the sleeve should be greater than or equal to twice the diameter of the steel bar.

4. Sleeve material parameters
The commonly used sleeve materials in male crimp contact extrusion are aluminum alloy and steel. Aluminum alloy sleeves are light in weight, easy to carry and operate, but have relatively low strength and are suitable for general occasions. Steel sleeves are high in strength and are suitable for occasions that require higher connection strength. Choosing a suitable sleeve material requires comprehensive consideration of processing requirements and use environment.
