The utility model content
The utility model technical matters to be solved is to provide the tep reel axle tube that a kind of surface finish is good, streamline is good, next step difficulty of processing is low blank.
The technical scheme of the utility model is following: a kind of tep reel axle tube blank; Comprise the axle tube body; Said axle tube body is made up of enlarged diameter section (A), reduced diameter section (B) and subpanel (1); Be enlarged diameter section (A) between said subpanel (1) and the reduced diameter section (B); Adopt straight transitions to connect between said enlarged diameter section (A) and the reduced diameter section (B), be provided with blind hole along axial line in the said axle tube body, this blind hole is by first section, second section, the 3rd section, the 4th section (a, b, c, d) four sections formations; Adopt arc transition between said subpanel (1) and the enlarged diameter section (A), this arc transition section forms cone; The length of said subpanel (1) is 17% of whole axle tube body length; The length of said enlarged diameter section (A) is 19% of whole axle tube body length, the length of said reduced diameter section (B) be really the axle tube body length 47%, extrusion forming of said blind hole; Wherein first section (a) is near the opening of subpanel (1); Adopt arc transition between this first section (a) and second section (b), be provided with a step (e) between said second section (b) and the 3rd section (c), (e) is tapered for this step; Said the 4th section (d) is conical section; This conical section base seal, and the 4th section (d) near reduced diameter section (B), and the bottom surface of said the 4th section (d) is near the outer face of the 3rd section (c); Said first section (a), second section (b), the 3rd section (c) and the 4th section (d) internal diameter are descending to successively decrease successively; Wherein the length of first section (a) is 2.4% of whole blind hole length; The length of second section (b) is 15% of whole blind hole length; The length of the 3rd section (c) is that the length of 45.5%, the four section (d) of whole blind hole length is 14% of whole blind hole length.
Adopt technique scheme, adopt arc transition between enlarged diameter section and the subpanel, surface finish is good; Process flowing line is good, and is close with the finished product structure, thereby makes next step difficulty of processing reduce; Saving in material, blind hole adopts an extrusion forming, and working accuracy is high; Streamline is good, and organizational structure is fine and close, has reduced the difficulty of next step processing.
In technique scheme: the external diameter of said enlarged diameter section (A) is 125mm, and the external diameter of said reduced diameter section (B) is 101mm.
, in technique scheme: the internal diameter of first section (a) of said blind hole is 136mm, and the internal diameter of said second section (b) is 71mm, and the internal diameter of said the 3rd section (c) is 59mm, and the internal diameter of said the 4th section (d) is decremented to 40mm by 59mm.
Beneficial effect: the utility model is reasonable in design, simple in structure, enforcement is easy, save raw MAT'L, and surface finish is good, and streamline is good, and next step difficulty of processing reduces.
