Abstract
The utility model relates to a special pipe for a piston pin, which is used for processing a high-speed diesel piston. The utility model comprises a through hole 1 of which the outer wall diameter is between 35 mm and 37 mm; the thickness of the pipe wall 2 is between 6.5 mm and 7.5 mm. The utility model does not need a press tool, and the processed piston pin has the advantages of compact structure, long service life, simple processing technology, labor saving, material saving, etc.
Description
The utility model is a kind of wrist pin dedicated pipe, especially for the dedicated pipe of processing high speed internal combustion engine pin.
At present, owing to do not have a kind of dedicated pipe that aims at the production wrist pin, thereby can only adopt the round steel cold punching to be pressed into base, be processed into wrist pin again through cutting, roughly grind, finish grinding.Thereby bring following problem, at first, course of working is loaded down with trivial details, the expense of taking a lot of work material; Secondly, stamping die in use weares and teares very big, make the specification of blank error occur, increased certain difficulty for the processing in road, back, be difficult to guarantee the quality of product of wrist pin, unless in the pin base process of stamping die punching press wrist pin, constantly check the stamping die wear condition, could guarantee the just size of blank; Once more, because blank is one time punching molded,, be difficult to guarantee the working life of wrist pin so its structure is tight less.
Task of the present utility model is that a kind of wrist pin dedicated pipe will be provided, it need not press tool and can be directly used in processing structure closely, the wrist pin of long service life, and processing technology is simple, labor and material saving.
Task of the present utility model is finished like this, a kind of wrist pin dedicated pipe that includes through hole 1, and its outer diameter is 35mm～37mm.
Below in conjunction with accompanying drawing the utility model is further described below.
Accompanying drawing is the utility model structural drawing.
The utility model adopts the round steel perforation, through pickling, phosphatization, saponification process, again through cold-drawn, namely Obtaining outer diameter is the hard-packed Special pipe for piston pin of 36mm, to supply with manufacturer's processing Piston pin is used.
The thickness of the tube wall 2 of the utility model Special pipe for piston pin is 6.5mm～7.5mm.
The utility model is supplied with and is produced piston pin manufacturer making piston pin, need not diel, adds The piston pin that the worker goes out has simple, the labor and material saving of close structure, long service life and processing technology.
Embodiment 1:
The perforation of employing round steel, through pickling, phosphatization, saponification process, again through cold-drawn, promptly obtaining outer diameter is 35mm, wall thickness is the wrist pin dedicated pipe of 6.5mm.
Embodiment 2:
The perforation of employing round steel, through pickling, phosphatization, saponification process, again through cold-drawn, promptly obtaining outer diameter is 36.5m, wall thickness is the wrist pin dedicated pipe of 7mm.
Embodiment 3:
The perforation of employing round steel, through pickling, phosphatization, saponification process, again through cold-drawn, promptly obtaining outer diameter is 37mm, wall thickness is the wrist pin dedicated pipe of 7.5mm.
Claims (2)
1, a kind of wrist pin dedicated pipe that includes through hole (1) is characterized in that its outer diameter is 35mm～37mm.
2, wrist pin dedicated pipe according to claim 1, the thickness that it is characterized in that tube wall (2) is 6.5mm～7.5mm.
