Key points of cold extrusion process for steel sleeve:

1. During construction, it is necessary to correctly master the three parameters of extrusion technology:

2. Insert the steel bars into the sleeve, aligning the end face of the sleeve with the marked line indicating the insertion position of the steel bars.

3. Mark the indentation position of the steel sleeve, align the position of the positive pressure mold, and make the direction of the mold movement perpendicular to the plane where the two longitudinal ribs of the steel bar are located, ensuring that the maximum pressure joint surface can be on the transverse ribs of the steel bar.

4. The crimping method involves pre crimping half of the steel bar joints and then lifting them to the work site to complete the other half of the steel bar joints. This can reduce the difficulty of high-altitude operations and accelerate construction speed.

Preparation work for the new process of cold extrusion connection for steel bar connection:

1. Conduct training for operators, who must pass the examination before being allowed to work. Those without an operating certificate are not allowed to carry out construction.

2. Determine the crimping force and number of crimping times through calculation and testing based on the diameter and material of the steel bars connected by crimping, as well as the selected connecting sleeve.

3. After the steel bar connecting sleeve is transported to the construction site, 5% of the processed steel sleeve should be selected for inspection and acceptance. Those who fail the inspection are not allowed to enter the site.

4. Choose suitable construction equipment and check whether the equipment is operating normally.

① Crimp sequence: Crimp from the middle to both ends one by one;

② Compression force: The size of the compression force should be tightly fastened between the steel sleeve and the steel reinforcement, and can be executed according to relevant regulations;

③ The number of crimping passes: It directly affects the quality of the joint and the construction speed, and can also be executed according to relevant regulations.

Precautions for cold extrusion of steel sleeve:

1. The axis connecting the steel bars should be kept in a straight line with the axis of the steel bar sleeve to prevent eccentricity and bending.

2. The connection quality must be implemented in accordance with the relevant regulations of the specifications.

3. For steel bar compression connection, the minimum center to center spacing of the steel bars is required to be 90mm.
