Abstract
A processing technology for a hollow external thread positioning bolt includes using a powder metallurgy technology and a core pulling mould to achieve injection moulding, appearance cleaning, descaling, fine drilling a screw shaft hole, finish machining a bolt cap and a semi-circle slip shaft groove, turning an external screw thread on a bolt, turning an adjusting shaft on the lower portion of the bolt, overall soaking to remove oil, derust and dry, and overall performing a blueing process. According to the processing technology for the hollow external thread positioning bolt, the manufacture quality and product requirements of parts can be guaranteed.
Description
Technical field
The present invention relates to be used on a kind of bottle opener hollow external screw thread pilot pin processing technology supporting with helical axis and that be located.
Background technology
Being used for parts supporting with helical axis and that be located on the bottle opener is not universal component; But profiled piece; So the manufacturing of parts all is unicity, particularity; This has just determined the manufacturing of parts that its special manufacturing process all must be arranged, otherwise is the function that can not guarantee the quality requirement and the product of product.
Summary of the invention
In order to solve the problem of above-mentioned proposition, the present invention provides a kind of hollow external screw thread pilot pin processing technology, and this hollow external screw thread pilot pin processing technology can guarantee the workmanship and the product requirement of parts.
The objective of the invention is to realize like this; Hollow external screw thread pilot pin processing technology adopts PM technique, utilizes the mold injects moulding of loosing core-outward appearance cleaning, scale removal-smart auger shell is revolved axis hole-fine finishining bolt cap, semicircle slide-bar groove-go out regulating shaft-integral body immersion oil removing, derust, dry-the integral body processing of turning blue at the bolt car of external screw thread-in the bolt bottom of getting on the bus out.
Characteristics of the present invention are that abnormally-structured, also usefulness processing mold is auxiliary to need particular process.
Description of drawings
Fig. 1 is the external view of hollow external screw thread pilot pin;
Fig. 2 is the cutaway view of hollow external screw thread pilot pin;
Fig. 3 is the vertical view of hollow external screw thread pilot pin.
Among the figure: 1, bolt cap; 2, semicircle slide-bar groove; 3, external screw thread; 4, bolt; 5, spiral axis hole; 6, regulating shaft.
The specific embodiment
Below in conjunction with accompanying drawing invention is described further.
In view, be example: adopt PM technique, utilize the mold injects moulding of loosing core-outward appearance cleaning, scale removal-smart auger shell is revolved axis hole 5-fine finishining bolt cap 1, semicircle slide-bar groove 2-goes out regulating shaft 6-at bolt 4 bottom cars and wholely soaks oil removing, derusts, dries-the integral body processing of turning blue at the bolt 4 external screw thread 3-that gets on the bus out with hollow external screw thread positioning cap.
