Description
Technical Field
The utility model relates to a pipeline pressure equipment field, concretely relates to with location angle bar of making electric smelting pipeline pressure equipment instrument.
Background
The industrial steel skeleton-polyethylene composite pipeline and pipe fitting are made up by using continuously-wound welded netted steel skeleton, high-density polyethylene and synchronously extruding and one-step-formed double-face anticorrosive pressure pipeline, and using welded steel cylinders with different shapes as reinforcing skeleton and polyethylene and injection-moulding them, and include electric smelting sleeve (direct), elbow with various angles, tee joint and reducing pipe fitting. The conveying medium of the industrial steel skeleton plastic composite pipe mainly takes various chemical liquid, brine and solid-liquid mixture taking water as a carrier, other liquid corrosive media are conveyed to meet the corrosion resistance of polyethylene plastic, and the tolerance range of a pipeline to the media can be provided by manufacturers.
The domestic frameless PE/pp pipeline is similar to the industrial electric melting pipeline, but the installation mode of the domestic PE pipeline is greatly different from that of the industrial electric melting pipeline: in the PE pipeline installation mode in life, the heating tools are used for respectively heating and melting the matching surfaces of the pipeline and the matched pipe fitting, and then the pipeline and the matched pipe fitting are quickly inserted together by heating to form welding, but in the welding mode, the welding seam is inserted together under the condition of continuously reducing the temperature, so that even if the two matching surfaces with softened welding seams are in an interference fit state, a lot of materials are still laterally extruded to one end instead of being moved greatly to be left on the matching surfaces, and the situation that great pressure is generated at the matching positions during cold insertion cannot be formed. The pressure generated by the material inserted in the welding seam in the thermal state is very small, the welding seam is cooled and solidified under low pressure, the effect of the pressure on eliminating defects is very limited, the quality of the welding seam is naturally poor, especially when the coaxiality error of the two matching parts is large during the insertion, the two matching parts move relatively in the radial direction during the solidification process, the welding quality is seriously influenced, the leakage-proof effect is naturally not good, and the method only has the advantage of simple press-mounting process.
Meanwhile, when industrial media are conveyed, the requirement of the industrial media on a pipeline is that the rated pressure of the industrial media is 16 kilograms per square centimeter without leakage, the industrial media is greatly different from the rated pressure of 4 kilograms of domestic tap water, in general, many industrial pipes are large-sized pipes, the flow area of a valve is larger than that of a domestic tap water pipe in many cases, and under the condition of the large flow area, the valve is used for throttling or opening the media, the operation frequency is greatly higher than that of a domestic water pipe, the density of the conveyed media can be far higher than that of water, so that the inertia of the media is larger, the water hammer phenomenon is easily generated repeatedly, namely the possibility of generating the water hammer phenomenon is higher than that of the tap water pipe, and the water hammer phenomenon can generate fluid pressure with remarkable destructive force, so that the welding seam of the pipe and the pipe for conveying the media can bear large pressure, the molding conditions of the plastic during welding of the welding seam are much inferior to those during injection molding.
Therefore, in order to ensure the welding quality, the stability of the press-fitting tool is particularly important, especially for the press-fitting tool of the bent pipe, but the existing press-fitting tool cannot be matched with the actual bent pipe in the manufacturing process, so that the press-fitting tool always cannot be matched with the actual bent pipe in use.
Disclosure of Invention
According to the problem that the background art provided, the utility model provides a solve with the location angle bar of making electric smelting pipeline pressure equipment instrument, it is right next the utility model discloses do further to explain.
The utility model provides a be used for making location angle bar of electric smelting pipeline pressure equipment instrument, includes T type base, is provided with the board location round platform that is used for the machine tool to add the location in man-hour on the T type base, is provided with the bent end location round platform in kind that is used for the elbow hole location in kind of elbow in kind on the board location round platform, and bent end location round platform in kind is loose interference fit with the elbow hole in kind.
Has the advantages that: compared with the prior art, use location angle bar after, processing elbow fitting has had the standard based on the elbow in kind occasionally for the pressure equipment instrument that produces can perfectly match elbow fitting when the pressure equipment, and then has ensured pressure equipment precision and quality.

FIG. 1: the structure of the utility model is shown schematically;
in the figure: the device comprises a material object elbow 300, a T-shaped base 301, a machine table positioning circular table 302, a material object elbow end positioning circular table 303, a gasket 305 and an alignment ring surface 307.
Detailed Description
A specific embodiment of the present invention will be described in detail with reference to fig. 1.
The utility model provides a be used for making location angle bar of electric smelting pipeline pressure equipment instrument, includes T type base 301, is provided with the board location round platform 302 that is used for the machine tool to add the location in man-hour on the T type base 301, is provided with the bent end location round platform 303 of the bent end of the object that is used for the elbow hole location of the object 300 on the board location round platform 302, and bent end location round platform 303 of the object is loose interference fit with the elbow hole of the object.
When the tool is used, the bent pipe fitting 300 is inserted into the positioning angle iron, the gasket 305 is arranged below the bent pipe fitting 300 in a cushioning mode, the bent pipe fitting is leveled on a workbench of a boring machine by adjusting the thickness of the leveling gasket 305, the shaft of the boring rod is aligned to be coaxial with the alignment ring surface 307 of the material object elbow, the positioning precision during machining is further guaranteed, and the press-fitting tool is machined and manufactured according to the standard.
