Description

Technical Field

[0001] The utility model relates to the technical field of steel wire mesh skeleton composite pipe processing equipment, in particular to a steel wire mesh skeleton composite pipe port flanging forming device. Background Art

[0002] When producing steel mesh skeleton composite pipes, it is necessary to perform flanging on the steel mesh skeleton composite pipes to facilitate the connection of subsequent pipelines. The traditional flanging process uses hot mold cold plastic. When the hot mold is pressed into the plastic pipe, due to the poor thermal conductivity of the plastic, the flanging part is heated and a temporary temperature stratification occurs. The temperature of the flanging part close to the flanging mold is higher, which is called the high temperature zone, and the temperature of the part close to the flanging flange sealing surface is relatively lower, which is called the low temperature zone. The plastic deformation in the high temperature zone is larger; the plastic deformation in the low temperature zone is smaller. After the hot flanging die is extruded, the plastic is in close contact with the flange sealing surface; when cooling, the plastic shrinks as the temperature decreases. The plastic in the high temperature zone shrinks and deforms more, and the plastic in the low temperature zone shrinks and deforms less. The plastic in the flanging part will separate from the flange sealing surface, forming a trumpet-shaped warp.

[0003] In response to the above-mentioned technical problems, a utility model patent with announcement number CN205631364U discloses a plastic-steel composite pipe flanging device, including a frame, a flanging flange, a flanging die and a flanging die driving device. A heating wire is provided on the side of the flanging flange facing away from the flanging die. The heating wire is spirally shaped and evenly coiled on the flanging flange. The flanging flange is heated, and the flanging die driving device is used to push the flanging die to the flanging flange, thereby achieving flanging. However, when this technical solution is actually applied, since the flanging die and the flanging flange are directly formed in a one-time flanging manner, after the flanging is completed, the shape, size, and flatness of the pipe flanging will fluctuate from the standard shape and size, and the product qualification rate is unstable.
