The steel bar straight thread rolling machine is a steel bar processing machinery widely used in the construction industry in recent years. It quickly rolls the end of the steel bar in one go to produce cold hardening at the head of the corrugated wire machine, thereby improving its strength and making the steel bar wire end the same as the base material. It consists of a frame, clamping mechanism, feed trailer, reducer and rolling head, cooling system, and electrical system.

Characteristics of steel bar straight thread rolling machine:

1. It can be rolled and threaded with high precision after the steel bars are stripped, and the consistency of diameter size is also very good;

2. It has a compact structure, simple operation, and significantly faster thread processing speed than other equipment;

3. We refer to its rib stripping device as the "foolproof type", which means it is easy to learn and understand, and the stability of rib stripping size is very good;

4. Only one steel bar clamping is needed to complete the thread processing, and the processing efficiency of the thread head is also very high;

5. It has strong automation, can automatically expand and retract the blade, and the noise generated by the equipment is also very small;

6. Its joint quality is stable and reliable, and the joint strength is higher than that of ordinary base materials;

7. It processes a wide range of steel bars and occupies less equipment.

8. This is also the most important point: the service life of the rolling wheel is long, and the use of additional costs for joints is also minimal;

Usage of steel bar straight thread rolling machine

（1） Preparation before processing

1. Connect the power cord and grounding wire as required, and connect the power supply. The power supply is a three-phase 380V 50Hz AC power supply. To ensure personal safety, please use an automatic switch with leakage protection function.

2. Add sufficient soluble coolant to the coolant tank (it is strictly prohibited to add oil-based coolant)

（2） Empty car test run

1. Connect the power supply. Check if the cooling water pump is working properly.

2. Operate the button and check if the electrical control system is working properly.

（3） Adjustment before processing

1. According to the diameter of the processed steel bars, replace the rolling wheel that is suitable for the processing diameter.

The relationship between the rolling wheel and the diameter of processed steel bars is shown in Table 1:

The outer diameter of the rolling wheel is 78.2, 69.4, and 59, and the diameter of the processed steel bar is 16-22, 25-32, 36-40. The pitch is 2.5, 3.0, and 3.5. 2. When replacing the rolling wheel, the washer that is suitable for the pitch of the rolling wheel should be replaced to ensure the correctness of the pitch. The relationship between the pitch and the thickness of the washer is shown in Table 2:

Pitch 2.5 3.0 3.5 washer 5.17 6.00 6.83 5.00 6.00 7.00 4.83 6.00 7.17 thickness 6.85 6.00 5.17 7.00 6.00 5.00 7.17 6.00 4.83

3. After the rolling wheel is adapted to the processing diameter, insert the tool holder that is adapted to the steel bar into the center of the rolling head, adjust the rolling wheel to make contact with the tool holder, pull out the tool holder, tighten the screws, and press the gear ring tightly to prevent it from moving.

4. For equipment with fixed positioning disks, according to the diameter of the processed steel bars, replace the positioning disks that are suitable for the processing diameter (the processing diameter is printed on the positioning disks). For devices with adjustable positioning disks, adjust them to the corresponding scale according to the positioning disk scale. When the rib stripping knife wears out, it also needs to be fine tuned.

5. Adjust the position of the rib stripping stroke block according to the specifications of the processed steel bars to ensure that the rib stripping length meets the required value.

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。

The steel bar straight thread rolling machine uses cutting and rolling to form threads in one go to achieve the purpose of reinforcing the steel bar end and thread processing. It solves the problem of pre-treatment of the steel bar end before processing, as well as the problem of multiple rolling required by similar equipment. This reduces the number of process processing and multiple steel bar handling on site, and improves the efficiency of on-site production and processing; The rolling machine uses one rolling head to achieve rolling processing of various specifications of steel bars, solving the problem of requiring one rolling head for each specification of steel bar end thread processing for similar equipment. The rolling machine adopts an internal cooling liquid to solve the problem of chip discharge during rolling processing. It has high automation intensity and automatic feed stop, reset and stop. The steel bar rib stripping straight thread rolling machine is a specialized equipment for processing steel bar straight thread heads. It uses a rib stripping knife to round the end of the steel bar, and then uses three hollow rolling wheels to roll the straight thread of the steel bar, thereby achieving the quality requirements for forming steel bar straight threads. Make the ribbed steel bar straight thread connection joint meet the A-level connection standard requirements of JGJI07-2003 "General Technical Specification for Mechanical Connections of Steel Bars".
