The total stroke of the two-step pipe expanding machine is 10-14.5 meters, and the loading and unloading structure of the pipe expanding machine is to accept the roller to mobilize the steel pipe to complete the loading and unloading.
The intermediate frequency power supply of the two-step tube expanding machine is installed in the front end of the equipment, the intermediate frequency coil is placed on the intermediate frequency coil mediation rack, the tube expanding core head mold is good, the original tube is put in, the water pump and the intermediate frequency power supply are turned on, and the intermediate frequency power is adjusted, so that the tube expanding core head mold and the tube can be heated. Start the pipe machine again, you can officially expand the pipe. The SCR, IF coil, compensation resonant capacitor, reactor and other components of the intermediate frequency power supply of the tube expanding machine need water cooling. The electrical control department of the pipe expanding machine is installed in the electric control box, and the travel switch is installed at both ends of the equipment travel. A kind of hydraulic pipe equipment of hot push two-step pipe expanding machine, which is used for seamless steel pipe expanding to meet the scarcity of large diameter steel pipes in the market. The push of the pipe expanding machine accepts the hydraulic cylinder drive, and can accept two cylinders or four cylinders according to the difference in pushing force. Generally accept two-step propulsion, saving cylinder stroke.
The two-step pipe expanding machine accepts the medium frequency power supply to feel the heating, the wire deception is outside the steel pipe, the steel pipe is coated with lead powder before pushing, and is transported into the hydraulic pushing machine through the loading rack, and after expanding, it is output through the unloading rack. It is the main equipment for hot expanding steel pipe, mainly designed for the domestic large diameter steel pipe production can not meet the market demand and the incomplete specifications of various steel pipes, comply with the production needs of small batch and various varieties of steel pipe, can meet the different materials of steel pipe expanding and various non-standard steel pipe expanding needs, is the main production process of large diameter steel pipe. It has been widely used in the equipment manufacturing industry of military industry, power station construction, aerospace industry and Marine industry, and has made great respect for the user's steel pipe industry and energy construction.
The equipment is used in the thermal expanding production of seamless steel pipe, straight seam welded pipe, coiled pipe and other steel pipes. Expandable steel pipe varieties are: all kinds of carbon steel, alloy steel, stainless steel and so on.
The pipe expanding machine is composed of several departments: the pipe expanding machine has the following parts: the hydraulic pipe expanding machine host, the automatic material structure, the hydraulic pump station, the pipeline device, the console, the motor control cabinet, the intermediate frequency power supply, the compensation capacitor, the water cable, the intermediate frequency coil regulating frame, the reactor. The pipe expanding machine expands the pipe diameter Φ1520mm and the wall thickness 120mm.
The pipe expanding machine can provide a series of pipe materials according to the customer. When the customer orders the expansion machine, we can order the different types of expansion machine and different production sizes and materials according to the customer. According to the model provided by the customer, we will produce the expansion machine to meet the customer's requirements within the time signed with the customer. The pipe expanding machine has the advantages of simple operation, high production efficiency and low cost. Operation process of pipe expanding machine: send the washed pipe to the rotary roll device on the center line of the diameter expansion machine. A rotating roller device, combined with the camera system, rotates the weld to 12 o 'clock to ensure that the weld enters the upper sector slot of the diameter expansion tool during the subsequent diameter expansion process. The lifting cone roller table lifts the pipe to the center line of the diameter tube expander and is controlled by a displacement sensor in the lifting hydraulic cylinder. The clamp car moves forward, controlled by a metal detector, detects that the end of the tube is stuck, and sends a signal to start the clamp car feed roller, the position is controlled by the encoder. During the driving process, a metal detector at the end of the diameter expansion tube head detects the front end of the tube to measure the position of the tube. In the pipe expansion production process, the pipe length and diameter expansion machine automatically controls the medium frequency power supply, heating the steel pipe to the required temperature, keeping constant, preventing the steel pipe and mold from being scrapped due to the temperature of the steel pipe is too high, and preventing the pull rod or mold from increasing the thrust of the thermal expansion machine due to the temperature is too low. The joint head automatically calculates the number of diameter expansion steps. The clamp mouth of the pipe can be rotated to avoid damaging the pipe wall. Compensate the diameter deviation of pipe, optimize the straightening effect of diameter pipe expanding machine.
The characteristics of pipe expanding machine; Mainly according to the customer to provide at the request of engineers, for customers to produce drawings. After the customer is satisfied, our company completes the processing system according to the customer's requirements, and passes the customer's inspection and transportation to the designated place. Each unit is equipped with two temperature measurement points to automatically control the temperature. According to the requirements of each customer, the pipe expanding machine equipment is designed for the domestic seamless steel pipe production can not meet the market demand, can be used to expand seamless steel pipe and coil pipe at will. The expansion tube diameter ranges from 60 to 1200mm. The pipe expanding machine has the advantages of heating steel pipe, saving energy, simplifying operation procedure and reducing labor cost, and can realize the normal production of multiple pipe expanding units.
Pipe expanding machine is a kind of equipment commonly used for hot expanding steel pipe, which is designed for the production specification of large-diameter seamless steel pipe is not enough to meet the market demand in the sea surface. The main power source of the pipe expanding machine is the two-cylinder or four-cylinder parallel equal-speed pushing machine. Pump station valve stands accept integrated form. According to the outer diameter and length of the desired extended steel pipe, set the power of the intermediate frequency heating power supply, the thrust and stroke of the cylinder. In the process of tube expansion, the system controls the medium frequency power supply to heat the steel pipe to the required temperature and keep it constant, which helps to stop the quality drop of the steel pipe and the scrap of the mold caused by excessive combustion of the steel pipe (high temperature), stop the break of the tie rod or mold caused by low temperature, and stop the unstable factors in the operation process. Compared with the artificially heated steel pipe, it is energy-saving and hygienic, simplifies the operation procedure, and reduces the labor cost.
Expanding machine manufacturers according to the requirements of customers to meet the approved equipment, usually in the company to order the expansion machine users have brought benefits. Aoguang pipe fittings equipment to receive your consultation!
