Abstract
The invention provides a manufacturing method for a pipe connector, and belongs to the technical field of manufacturing of metal pipe fittings. The pipe connector manufactured by using an existing welding and manufacturing method is high in cost, low in production efficiency and low in firmness. According to the method, an inner hole of an outer thread connector is machined to two sections with different diameters and the two sections correspond to a thread section and a hexagonal surface section on the outer surface of the outer thread connector respectively; the diameter of the inner hole corresponding to the hexagonal surface section is slightly small and the inner holes of the two sections are connected by an inclined plane; at least two grooves along the direction of the central line of the hole are formed in the wall of the inner hole corresponding to the outer thread connector and are formed along the peripheral direction of the inner hole; a metal pipe penetrates into the inner hole of the outer thread connector to form an assembly; the assembly is arranged on a lower die of a punching machine and the shape of a die cavity of the lower die is adapted to the outer shape of the outer thread connector; and the metal pipe is stamped into an inner cavity at the end of the metal pipe by an upper die, so that the wall of the metal pipe is tightly combined with the wall of the inner hole of the outer thread connector and is embedded into the grooves in the wall of the inner hole. By adopting the manufacturing method, the environmental protection property is improved, the cost is saved, the manufacturing is simple and rapid and binding force of the pipe connector is high.
Description
Technical field
The invention belongs to metal tube manufacturing technology, especially relevant with a kind of pipe joint manufacture method.
Background technology
The pipeline of automobile water circulation is connected by multistage, these pipelines generally form pipe joint by metal tube and the male connection being arranged on pipe end, male connection outer surface is divided into two sections, one section arranges screw thread, and one section arranges hex surface, and metal tube and male connection adopt welding, need to expend wlding and electric energy, cost is high, and pipe joint firmness is not high again, and production efficiency is low.
Summary of the invention
The object of the invention is intended to solve the existing welding manufacture method of employing and manufactures the problem that pipe joint cost is high, production efficiency is low, pipe joint firmness is not high, provides a kind of pipe joint manufacture method manufacturing simple and fast.
For this reason, the present invention is by the following technical solutions: a kind of pipe joint manufacture method, it is characterized in that, male connection endoporus is processed into two sections that diameter does not wait, the thread segment of the corresponding male connection outer surface of difference and hex surface section, the diameter of bore of corresponding hex surface section is smaller, connect with inclined-plane between two sections of endoporus, offer on the inner hole wall of corresponding thread segment more at least twice along the groove in centerline hole direction, this multiple tracks groove is along the distribution of endoporus circumference, metal tube penetrates male connection endoporus and forms assembly, this assembly is placed on punching machine lower mold, counterdie mold cavity shapes adapts to male connection outer shape, with stamping press-in pipe end inner chamber, metal tube is extruded reaming, metal pipe-wall and male connection inner hole wall are combined closely, and the groove embedded on inner hole wall.
Use the present invention can reach following beneficial effect: the present invention adopts the cold stirrup technology of riveting to replace method for welding, and expend without the need to solder, improve the feature of environmental protection, saved cost, manufacture simple and direct, pipe joint adhesion is high, and firmness is high.
Detailed description of the invention
Manufacture method of the present invention be male connection endoporus is processed into diameter not wait two sections, the thread segment of the corresponding male connection outer surface of difference and hex surface section, the diameter of bore of corresponding hex surface section is smaller, connect with inclined-plane between two sections of endoporus, offer on the inner hole wall of corresponding thread segment more at least twice along the groove in centerline hole direction, this multiple tracks groove is along the distribution of endoporus circumference, metal tube penetrates male connection endoporus and forms assembly, this assembly is placed on punching machine lower mold, counterdie mold cavity shapes adapts to male connection outer shape, with stamping press-in pipe end inner chamber, metal tube is extruded reaming, metal pipe-wall and male connection inner hole wall are combined closely, and the groove embedded on inner hole wall.
