The Manufacturing Process and Functional Composition of the Elbow Making Machine

The elbow making machine has active chemical properties, low thermal conductivity and large heat capacity at high temperature. When welding stainless steel elbows, oxidation and air pollution are prone to occur in the welds in the pipe, which seriously affects the welding quality. Therefore, when welding stainless steel elbows, it is necessary to use protective gas in the pipeline to solve the problem of high temperature oxidation of the internal weld.

1. Application of manufacturing process regulations of elbow making machine

This process is suitable for the manufacture of hot push formed carbon steel butt welded long and short radius elbows.

2. Precautions for the process of elbow making machine from blanking to finished product

Adjust the center height of the mandrel and keep it consistent with the center of the pusher. Adjust the front and rear travel limits of the pusher. Adjust the working pressure and propulsion speed of the pusher.

Check whether the hydraulic, electrical and cooling systems work normally and whether the movements are sensitive. When lubricating, apply a thin and uniform layer of graphite powder to the inner wall of the pipe.

Start the water pump, the intermediate frequency power supply, adjust the intermediate frequency power, and match the propulsion speed. The front card of the propulsion machine slowly advances the tube blank on the mandrel rod. The tube blank is heated by the induction coil. Under the action of thrust, the tube begins to expand at high temperature. Diameter, bend, take off the mandrel, complete the bending process.

3. The composition of the elbow making machine

The elbow making machine is mainly composed of alloy core head, intermediate frequency coil bracket, intermediate frequency coil, outlet bracket, push plate door, hydraulic opening cylinder, push plate, rear gate, hydraulic lifting cylinder, main cylinder, cylinder rear bracket, feeding core rod, large It is composed of chassis, cylinder bracket, motor, axial piston pump, integrated block ( hydraulic control valve installed on it ), etc.

elbow making machine host, hydraulic pump station, console, motor control cabinet, intermediate frequency power supply, compensation capacitor, water cable, intermediate frequency coil adjustment frame, reactor. elbow making machine is the main equipment for producing elbow fittings.

The elbow making machine wears custom-made molds to produce and process custom-made elbow fittings. The design of stiffeners at the head of the elbow and the body of the bed is annealed to eliminate internal stress. The overall rigidity is light enough to prevent deformation. When assembling the drive spindle, it is directly inserted from the upper part of the machine head, which is accurate in installation and convenient in maintenance.

The elbow spindle and the transmission sprocket are integrally forged, integrally machined, and integrally hobbed, with uniform force, double-cylinder drive, and quick reset. During the return process, there is a throttling buffer close to the starting point, which greatly improves the reset accuracy and work efficiency. The elbow making machine has automatic feeding, oil cylinder, mandrel, core head and so on.

The elbow fittings produced by the elbow making machine are mainly used for elbow installation in pipeline installation. When the drive spindle of the elbow making machine is assembled, it is directly inserted from the chuck, which is accurate in installation and convenient in maintenance. When pushing the elbow making machine, the pipe fittings of long radius elbow and short radius elbow can be selected, which can be corrected after pushing and bending.

The elbow making machine adopts analog control and low current mode. In order to control the high voltage at work, operate safely, prolong the service life of the heating coil, and improve the thermal energy of the heating coil.

4. The functions of the elbow making machine are mainly divided into

The main function of the elbow making machine is to wear the anchors that need to produce elbow fittings, and produce and process elbow fittings of various materials, such as carbon steel, alloy steel, stainless steel, etc. In the production process, the main function of the elbow making machine is to use the hydraulic cylinder as the propulsion element, with powerful power, infinitely variable speed, simple operation, and high yield of elbow pipe fittings.

The elbow making machine is equipped with a matching hydraulic pump station, adopts a large-volume oil tank, and adjusts the propulsion speed by adjusting the flow rate of the control valve. The hydraulic system adopts integrated oil circuit and electromagnetic overflow technology, which greatly reduces the heat generation of the hydraulic system. Reduce energy consumption and optimize the entire work environment.
