Abstract
Description
technical field
[0001] The invention relates to the field of welding technology, in particular to a steel-plastic composite pipe skeleton positioning device and method without secondary processing. Background technique
[0002] The existing positioning technology for the steel skeleton embedded in the mold cavity in the steel-plastic composite pipe fittings, although there is a positioning method for whether there is exposed metal or not, after the product is produced using the existing skeleton positioning method, it needs to be aligned. The cavity left by the positioning block on the product is subjected to secondary sealing processing. This positioning method will not only increase the production cost of the pipe fittings, but also because of the existence of secondary processing, in the plugging position of the pipe fittings, it is easy to cause a certain leakage risk to the operation of the pipeline due to the quality of the plugging.

Embodiment Construction
[0029] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0030] Such as Figure 1-8 As shown, the present invention provides a steel-plastic composite pipe skeleton positioning device that does not require secondary processing, including a mold 1, a skeleton body 2, and a plastic positioning nail 3; the mold 1 is detachably divided into upper and lower parts, and the mold 1. There is a mold cavity suitable for placing the skeleton body 2 inside; a placement groove 11 is arranged around the mold cavity of the mold 1; a support nut 21 is fixedly arranged on the surface of the skeleton body 2; the plastic positioning nail 3 is fixed on the support nut 21; When the skeleton body 2 is placed in the mold cavity, the plastic positioning nail 3 is inserted into the placement groove 11 to realize the positioning of the skeleton body 2, and the skeleton body 2 is l...
