7.5kw Rebar Processing Machine Upset Cold Forging Machine

Description of Rebar Upset Cold Forging Machine

The steel bar upsetting machine uses the principle of hydraulic cold heading to plastically deform the end of the steel bar, increasing the diameter by 4~6mm, and then processing the thread. The actual cross-sectional area after processing the thread is larger than the original steel bar cross-sectional area, and the tensile strength of the joint is improved.

Technical Parameter

Preparation before processing
1. Connect the power cord and ground wire as required, and turn on the power. The power supply is a three-phase 380V 50Hz AC power supply. To ensure personal safety, please use an automatic switch with a leakage protection function.
2. In the coolant tank, add enough soluble coolant (oil-based coolant is strictly prohibited).
Empty test run
1. Turn on the power. Check whether the cooling water pump works normally.
2. Operate the button to check whether the electrical control system works normally.
Adjustment before processing.
1. According to the diameter of the steel bar to be processed, replace the thread rolling wheel suitable for the processing diameter.
2. While replacing the thread rolling wheel, replace the washer that is suitable for the pitch of the thread rolling wheel to ensure the correctness of the thread pitch.

3. After the thread rolling wheel is adapted to the processing diameter, insert the tool setting rod suitable for the steel bar into the center of the rolling head, adjust the thread rolling wheel to make it in contact with the tool setting rod, pull out the tool setting rod, tighten the screw, and compress the ring gear, making it impossible to move.
4. For the equipment with a fixed positioning disc, according to the diameter of the steel bar to be processed, replace the positioning disc that is suitable for the processing diameter (the processing diameter is printed on the positioning disc). For the equipment with an adjustable positioning plate, adjust the corresponding scale according to the scale of the positioning plate. When the rib stripping knife is worn out, it needs to be fine-tuned.
5. According to the specifications of the steel bars to be processed, adjust the position of the rib stripping stroke block to ensure that the rib stripping length reaches the required value.
6. According to the specifications of the steel bars to be processed, adjust the position of the travel switch pressure block to ensure that the effective length of the rolling thread reaches the required value.
