The steel bar upsetting machine uses the principle of hydraulic cold heading to cause plastic deformation of the steel bar end, increasing the diameter by 4-6mm, and then processing the thread. Make the actual cross-sectional area of the processed thread larger than the original cross-sectional area of the steel bar, and improve the tensile strength of the joint.

This type of threaded joint, after upsetting, has been tested by tensile testing and is completely broken in the base material, making it suitable for projects with higher requirements. After being upsetting by the upsetting machine, the strength of the base material of the steel bar is much higher than before, making it suitable for some projects with strict process requirements.

Product Usage:

Used for upsetting the steel bar head, after upsetting, the strength and tensile strength of the steel bar base material are improved, and then rolling and connecting are carried out. Improved the safety of the project.

The device is easy to operate and can be operated by one person. After the steel bars are placed, the foot pedal switch under the tower will automatically operate, saving labor and reducing worker fatigue. It can be used for continuous processing and production.

If the customer does not provide a definite type and specification of the sleeve, the customer should correctly explain their type, specification, and requirements, and sign the contract under the condition of mutual understanding between the supply and demand parties。

　1、The customer communicated the product type, specifications, and dimensions to our salesperson。

　2、Received customer specifications and dimensions, provided sleeve quotation (price list) for the customer。

　3、Specific agreement: delivery time, special requirements, and other matters。

　4、After placing the order and making payment, our company will arrange shipment as soon as possible。

Working characteristics of upsetting machine:

1. High strength: The net cross-sectional area of the steel bar after cutting the thread in the upsetting section is still greater than the original cross-sectional area of the steel bar, that is, the thread does not weaken the section, thus ensuring that the joint strength is greater than the strength of the steel bar base material

2. Stable performance: The strength of the joint is not affected by the tightening torque, and loose or insufficient threading of 2-3 threads will not significantly affect the strength of the joint, eliminating the influence of manual factors and force measuring tools on the joint performance.

3. Fast connection speed: Use a connecting sleeve to connect the steel bars and tighten them. Due to the large thread pitch and fewer threads to be screwed in, there is no need to use a torque wrench, which speeds up the connection speed.

4. High production efficiency: On site upsetting and cutting of each wire head only takes 30-50 seconds, and each set of equipment can process 400-600 wire heads per shift.

Safety operating procedures for steel bar upsetting machine

1. Staff must undergo technical training and pass the skill assessment before they can operate on duty

2. Before formal processing, the equipment should be debugged and run for 2-3 minutes without load, and can only be processed after normal operation.

3. The cutting of steel bars should be straight and free from bending.

4. Before processing steel bars, the machine should return to its initial position before processing to ensure consistent processing work.

5. Processing steel bars should not have transverse cracks, and any equipment malfunctions should be promptly resolved.

6. Add clean No. 46 hydraulic oil when refueling.

7. Staff should comply with the safety protection regulations for engineering personnel.
