Necking machine

The necking machine adopts CNC fine milling, with high flatness, no concave and convex surface, and controlled by CNC system. Hydraulic power transmission, all cylinders use 120 × double cylinders, and the pressure can reach 16 tons, and the necking can be formed in 2 seconds. The frequency converter adopts Shanghai national standard Licheng motor, with high stability. The die lock and die pressing die of plated Le 12 are made of die alloy steel, which should not be cracked or deformed during the pipe head travel. We can also customize machines and abrasives according to customer requirements, and complete your requirements on time and quality

the necking machine can easily solve the manual welding method of various types of pipes. The necking machine does not need welding, and the direct butt joint after necking also reduces the use of pipes. The positioning device is added to solve the problem of different length of steel pipes and iron pipes. The efficiency is improved, and the production effect is 3000-5000 pieces per day. The structure is simple, the use is convenient, and the appearance is reasonable, so it does not occupy land. The die used for head shrinking is die alloy steel. The die can be replaced and customized according to the common pipe type of customers
