Elbow machine push elbow making process

• Elbow machine push elbow making process

The production and manufacturing process of elbow machine, elbow is a kind of pipe fitting for pipe turning, there are 90 degree elbow, 45 degree elbow and so on, can be manufactured according to the engineering needs, different materials and different pressure elbow production and manufacturing process is different, so far,Elbow manufacturers commonly used seamless elbow production and manufacturing process are hot push elbow (medium frequency induction heating elbow machine), push elbow, butt-welding elbow these several production and manufacturing methods.Hot push elbow is a seamless elbow manufacturing process, the use of elbow pushing machine, core die and heating device, the use of the blank set on the mold in the elbow pushing machine to push forward, in the pipe running heating expansion and bending forming process.The deformation characteristic of hot push elbow is to determine the diameter of pipe billet according to the constant volume of metal material before and after deformation. When using the pipe, the diameter of the pipe is smaller than that of the elbow. In the heating deformation of the elbow, the compensation is made to the expansion diameter

While thinning other parts, the elbow with uniform wall thickness is obtained. This is the manufacturing process of push-making elbow.Push machine push out of the elbow, beautiful appearance, uniform wall thickness can be continuous production and manufacturing, mass production can elbow push system, so the general carbon steel elbow, alloy steel elbow push system adopted by the main technology of manufacture is machine drive system elbow manufacture, and also the application in some of the specifications of the stainless steel elbow forming (thermoforming bend machine advantage).

Comprises a base frame, the middle of the base frame is provided with a bracket, which is characterized in that the bracket is provided with an elbow mold;The back of the elbow mould is provided with a hydraulic device, the middle is provided with a push frame, the front end is provided with an electric heating device, the push frame is installed on the elbow mould;The push frame is provided with a control box, the control box is electrically connected with a hydraulic device and an electric heating device.Further, the hydraulic device comprises a hydraulic pump and a hydraulic cylinder.The electric heating device comprises an intermediate frequency heater and an electric heater;The electric heater is a heating coil.The utility model comprises an elbow mold, a hydraulic cylinder and a push frame are arranged on the guide rod of the elbow mold, and a heating coil and a mold part are arranged in the front part of the guide rod.The utility model saves a great deal of manpower and time, and the utility model can process the elbow of large diameter by using the blank of small diameter, and the type of elbow is increased.

An elbow machine relates to a device for pushing and making an elbow.It is mainly designed to solve the problem of large wall thickness difference of pressing elbow.It includes frame, intermediate frequency heater, hydraulic system, with fixed bed fixed to the frame of the back-end, fixed with a hole at the center of the machine, the oil cylinder is fixed on the fixed table, no bar and rod of oil cylinder cavity respectively through the pipe connected to the hydraulic system, have a haircut and the oil cylinder cylinder rod fixed contact, have a haircut central hole, intermediate frequency heater with heating coil wire connection,Wedge key hole is at the back of the core rod from the middle of the heating circle and have a haircut in the hole and the center of the fixed bed hole through the wedge key to wear in the key hole wedge core rod, activity semicircle card board is composed of upper and lower two semicircle card board, card board activity half of upper and lower two semicircle card board are installed on the surface before have a haircut at the same time set on the mandrel and with core rod gaps.The advantage is that the produced elbow wall thickness is uniform
