Abstract

The invention discloses a steel-plastic composite pipe framework positioning device and method without secondary machining. The steel-plastic composite pipe framework positioning device comprises a mold, a framework body and plastic positioning nails; the mold is detachably divided into an upper part and a lower part, and a mold cavity matched with the containing framework body is formed in the mold; placing grooves are formed in the periphery of the mold cavity; support nuts are fixedly arranged on the surface of the framework body; and the plastic positioning nails are fixed on the support nuts. When the framework body is placed in the mold cavity, the plastic positioning nails are inserted into the placing grooves to realize positioning of the framework body, and the framework body is jacked up through the support nuts, so that the framework body is suspended relative to the mold, and the uniform distance between the framework body and the mold cavity wall of the mold is ensured. Bymeans of the device, a steel framework can be effectively positioned, meanwhile, when the steel-plastic composite pipe is completed, only redundant plastic positioning nails need to be cut off, secondary plugging machining is not needed, and it is guaranteed that the risk of leakage of the pipe due to plugging quality is avoided.

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. Contents of the invention [000...
