A hot-push elbow machine is a device commonly used in pipeline engineering to bend pipes into the desired shape. It has the characteristics of high efficiency and accuracy, and can meet the needs of various complex pipeline systems. The push process of the hot push elbow machine will be introduced in detail below.
Step 1, determine the design requirements and material selection. Before the hot push elbow machine is pushed, it is necessary to clarify the design requirements such as the required bending Angle, bending radius, and bending type. At the same time, according to the engineering requirements and material characteristics, the appropriate pipe is selected for pushing.
Step two, prepare for work. Preparation of the tube is required before rolling. First, the bending position and Angle of the pipe are determined by measuring and marking according to the design requirements. Then, the pipe is cleaned and oxides are removed to ensure that its surface is smooth and clean.
Three steps, heat the tube. The push principle of the hot push elbow machine is to make the pipe soft by heating it, so that it can be bent. When heating, it is necessary to select the appropriate heating method and temperature control according to the characteristics and thickness of the pipe material. The commonly used heating methods include flame heating, resistance heating and induction heating.
Four steps, bend the tube. When the pipe reaches the appropriate heating temperature, it can be bent using a hot push elbow machine. The hot push elbow machine usually consists of two main parts: the bending frame and the bending die. First, the tube is placed into the bending rack and the rack is adjusted to the desired bending radius. The tube is then bent to the desired Angle using a suitable bending die. During the bending process, it is necessary to ensure that the pipe is evenly heated and stressed to avoid excessive deformation or fracture.
Five steps, cooling and curing. Once the bending of the tube is complete, it needs to be cooled and cured to maintain the desired shape and strength. Usually, it can be cooled by water cooling or natural cooling. During the cooling process, attention should be paid to controlling the cooling speed and temperature to avoid deformation or stress concentration of the pipe.
Six steps, check and trim. After the cooling of the pipe is completed, it needs to be inspected and trimmed to ensure that it meets the design requirements and quality standards. Usually, measuring tools (such as calipers, Angle gauges, etc.) can be used to check the bending Angle and bending radius of the pipe. If there is a problem or does not meet the requirements, it can be repaired or re-pushed.
In summary, the push process of the hot push elbow machine includes determining the design requirements and material selection, preparation, heating the pipe, bending the pipe, cooling and curing, inspection and dressing steps. Each step requires careful operation and control to ensure that the bend is pushed to meet the requirements. This is a process that requires skill and experience, and requires skilled operators to operate it.
