Description

Technical Field

[0001] The present application relates to the technical field of pipe fitting processing, and in particular, to a steel-plastic pipe fitting processing device and a processing method for steel-plastic pipe fittings. Background Art

[0002] Steel-plastic pipe fittings, also known as steel-plastic composite pipe fittings, refer to pipe parts formed by punching and rolling a steel plate into a tubular reinforcing skeleton and then injection-molding and compounding it with plastic. In the production process of steel-plastic pipe fittings, first, the reinforcing skeleton with plastic positioning nails installed at specified positions is placed at the specified axial position on the inner side wall of the mold cavity, and then the mold is closed and injection-molded with molten plastic, so that the reinforcing skeleton is fixed at the specified position in the plastic matrix, and steel-plastic pipe fittings are produced. When using plastic positioning nails to position the skeleton, due to the low strength of the plastic positioning nails, at an injection pressure exceeding 10 MPa, the position of the skeleton is not accurately positioned. If the deviation is serious, short-circuit faults are very likely to occur during electrofusion welding, and the pipe fittings fail; if it cannot be ensured that the plastic positioning nails are completely melted and completely fused with the molten plastic during the injection molding and cooling process, moisture and other media will penetrate to the surface of the steel plate during immersion cooling and use, resulting in yellow water seeping out from the surface of the pipe fittings during electrofusion welding, and the steel plate will corrode during application. After a long time, the pipe fittings fail, causing pipeline leakage.

[0003] For a mold with a reinforcing skeleton installation limiting device in the cavity, it can directly place the reinforcing skeleton at the specified position and accurately position it without using plastic positioning nails, and steel-plastic pipe fittings with limiting holes can be produced by adopting the injection molding process of molten plastic; then, it is necessary to manually use special equipment to extrude molten plastic to fill each hole one by one, and then put it into a water tank for cooling and shaping and then turn it on a lathe.

[0004] The operation of manually using special equipment to extrude molten plastic to fill each hole one by one takes a long time, has a high labor intensity, and the quality is difficult to guarantee, resulting in low efficiency and a high defective rate. Summary of the Invention

[0061] The implementation principle of the processing method of the steel-plastic pipe fitting in the embodiment of the present application is as follows:

[0062] First, a perforated pipe fitting 91 is injection molded through a mold.

[0063] Then, the perforated pipe fitting 91 is sleeved on the rotating block 51, and then the pressing block 53 presses against the side wall of the perforated pipe fitting 91. Then, the fixed sleeve 21 and the rotating sleeve 22 are sleeved on the perforated pipe fitting 91, and the axis of the fixed sleeve 21 coincides with the axis of the perforated pipe fitting 91. Adjust the positions of the four baffle plates so that the four baffle plates form a first baffle ring and a second baffle ring. Then, rotate the rotating block 51 and the rotating sleeve 22.
