Main types of equipment<\/h2>\n

NC sawing and threading production line is a device that can automatically complete the actions of fixed length cutting, conveying and threading of reinforcement through the setting of NC program. In the construction industry, the connection of reinforcement is a very important part. The connection methods of reinforcement mainly include lap joint, welding, mechanical connection and so on. The threaded connection in mechanical connection is very commonly used in component connection, so a large number of rebar with thread at the end need to be used. Most construction sites also need to use a large number of rebar with thread at the end. The common processing method is to cut a large number of straight bars in fixed length, and then manually put the rebar one by one into the threading machine for threading. The efficiency of such a processing process is very low, and the amount of labor of workers is very large. If the steel bar requiring threading has a large diameter and long length, it even needs two people to lift the steel bar. It is precisely because of this market demand that the equipment manufacturer has developed a NC sawing and threading production line. CNC sawing and threading production line is a combination of sawing production line of mature products in the past and automatic threading production line. At present, the main machines of the sawing production line are processed by band sawing machine, so there is no difference in processing capacity. Even 10 50 reinforcement bars can be sawed at the same time, but the sawing time is long and the wear of the saw blade is fast. Sawing and threading production lines can be classified into one type, because the difference of each equipment is only the mechanism used in the realization of function.<\/p>\n

Technical parameters and functional features<\/h2>\n

Table 2-6 shows the technical parameters of a NC sawing threading production line. It can be seen from the table that the cutting capacity of NC steel bar sawing production line can also be cut \u03c6 50, and if calculated according to the maximum width of 600mm, 11 bars can be sawn at a time \u03c6 50 reinforcement. However, when cutting large-diameter reinforcement, the cutting feed of the sawing machine should also be reduced. It takes about 1 minute to cut, so the advantage is not great in terms of work efficiency. The production speed of the automatic threading production line is about once every 40s. If the threading at both ends is about 80s, a reinforcement can be completed. It can be seen that the output of NC steel bar sawing production line is much larger than that of automatic threading production line. If you want to make efficient production and maximize the use of sawing production lines, you need to increase the number of automatic threading production lines.<\/p>\n

The NC sawing and threading production line has the following characteristics:<\/h3>\n

(1) Cut by sawing, and the end face is flat.<\/strong><\/p>\n

Because the CNC sawing threading production line uses a sawing machine to cut the reinforcement, and the feed speed of the saw blade is slow, it can form a relatively flat end face, which is conducive to the subsequent processing and butt joint of the reinforcement. Manufacturers with higher requirements can be equipped with automatic grinding production lines.<\/p>\n

 <\/p>\n

(2) High cutting capacity and strong adaptability.<\/strong><\/p>\n

CNC steel bar sawing production line can process \u03c6 12 ~ 50 straight bars, and can be sawn in batches.<\/p>\n

 <\/p>\n

(3) The lifting baffle is positioned and cut accurately.<\/strong><\/p>\n

The CNC steel bar sawing production line adopts lifting baffle and longitudinal pressing plate to lock the steel bar position, the cutting size is accurate, and the length tolerance of the steel bar after cutting is generally \u00b1 LMM. The rear of the ship has also been realized automatically<\/p>\n

 <\/p>\n

(4) Automatic threading is fast and efficient, reducing labor intensity.<\/strong><\/p>\n

The CNC sawing and threading production line automatically processes the whole process of reinforcement from raw materials to finished products, which greatly reduces the labor intensity of workers, and the positioning of reinforcement threading is more accurate and efficient.<\/p>\n

 <\/p>\n

(5) Flexible configuration and diversity of choices.<\/strong><\/p>\n

CNC sawing and threading production line can be flexibly matched, and can be configured with single line automatic threading production line, double line automatic threading production line, automatic grinding production line, etc., which can be suitable for large and small-scale production.<\/p>\n

The discharge machine of the NC steel bar sawing production line is turned over to the standby rack of the automatic threading production line at one time, which has high production efficiency. In addition, for some manufacturers with high requirements for the use of reinforcement, they can also add a grinding production line after the threading process to further grind the end face of the reinforcement after threading to meet the use requirements. Compared with traditional manual threading, this set of production equipment has high degree of automation, fast production speed, high thread processing quality and low labor intensity of operators. The working process of the whole production line is to lift a certain amount of reinforcement and place it horizontally on the conveyor roller of the feeder of the NC reinforcement sawing production line. According to the setting of the sequence, the CNC steel bar sawing production line will automatically complete the actions of conveying, positioning, pressing, sawing and turnover to obtain the fixed length straight bar steel bar to be threaded.<\/p>\n
