There are two main ways to connect steel wire ropes: mechanical crimping method and heat treatment knotting method. The mechanical crimping method uses special crimping tools to connect the steel wires of two steel wire ropes through pressure and deformation. The heat treatment knotting method uses high temperature to tie the two steel wire ropes together to form a whole.

1. Mechanical crimping method:

Mechanical crimping method is a commonly used method for steel wire rope docking, commonly used in engineering such as connection, repair, and reinforcement of steel wire ropes. It has the characteristics of simple operation, low cost, and good results. Here are the operational steps:

(1) Preparation: Understand the types and methods of steel wire rope docking, select corresponding crimping molds and equipment based on the model and crimping tools of the docking steel wire rope, and ensure the accuracy of the crimping machine and the cleanliness and dust-free surrounding environment.

(2) Cutting steel wire rope: Cut the original steel wire rope according to the required length to ensure that both ends of the cut steel wire rope are flat and free of burrs.

(3) Preparation of crimping molds: Confirm the required crimping molds for the crimping machine, generally including the pressure head, oil seal, spring, pressure head shaft, etc. The number and specifications vary depending on the diameter and category of the steel wire rope.

(4) Adjusting the mechanical parameters of crimping: Adjust the parameters according to the needs of wire rope docking and predetermined parameters to avoid unstable or abnormal wire rope docking.

(5) Placing steel wire ropes: Place the two connected steel wire ropes in a predetermined specific direction on the crimping mold and clamp them tightly.

(6) Start docking: Start the crimping machine, adjust the pressure and speed according to the prompts of the crimping machine. The crimping machine will rotate the two steel wire ropes into a whole through deformation and pressure, and the deformation of the steel wire will replace the need for welding or knotting.

(7) Post processing: After completing the crimping of the wire rope, it is important to inspect and clean the surface of the wire rope. For defects such as rust spots and scratches on the surface, they should be treated to avoid affecting subsequent use.

2. Heat treatment knotting method

The heat treatment knotting method involves mixing the steel wires of two or more steel wire ropes together and knotting them into a whole under high temperature conditions. The specific operation steps are as follows:

(1) Cutting steel wire ropes: Cut two or more steel wire ropes according to the required length, and ensure that the end face of the cut steel wire is flat and free of burrs.

(2) Preheating: Insert the cut steel wire rope into an oven or furnace for preheating and heating. The heat treatment temperature should be selected according to the type, thickness, and material of the steel wire rope, and the appropriate temperature and time should be around 600 degrees Celsius for treatment.

(3) Knotting after heat treatment: After preheating and heating, a portion of the surface of the steel wire will melt. Two or more steel wire ropes will be mixed together in the heat treated state, and then pinched together with pliers to form a whole.

(4) Cooling of steel wire rope: Take out the treated steel wire rope and place it in a relatively stable temperature place for static use. After cooling, use a grinding wheel for surface processing and cleaning.

Overall, mechanical crimping method and heat treatment knotting method are both common methods for connecting steel wire ropes. Depending on the specific application field, the root
