Abstract
The invention discloses the parts on a kind of bicycle, particularly a kind of bicycle club, club body including integral type cold-heading molding, one side end of described club body is provided with bulb part, its end side is provided with upset portion, and the end face of this side end is provided with the buried via hole axially carrying out extending along this club body.Which solving the technical problem of " on the premise of ensureing bicycle club high intensity, reduce its weight ", it is high that it has possessed structural strength, the light-weighted advantage of product.
Description
Technical field
The present invention relates to the parts on a kind of bicycle, particularly a kind of bicycle club, and above-mentioned bike polo
The cold-heading molding technique of bar.
Background technology
Bicycle club is with the high-intensity exercise part rotated by crank shaft.Select 6061 aluminium alloys, original be
Solid.Therefore, the weight of bicycle club is relatively large, and production cost is of a relatively high.
Summary of the invention
The invention aims to solve above-mentioned the deficiencies in the prior art and provide a kind of and ensure that high intensity product is light
The bicycle club quantified.
To achieve these goals, a kind of bicycle club designed by the present invention, including the ball of integral type cold-heading molding
Bar body, a side end of described club body is provided with bulb part, and its end side is provided with upset portion, and this side
The end face of end is provided with the buried via hole axially carrying out extending along this club body.
Above-mentioned a kind of bicycle club, its club body uses integral type cold-heading molding, it is ensured that the high intensity of club body；
Meanwhile, above-mentioned club body axially offers buried via hole along club body, thus time at utmost, makes product lightweight, with
Time reduce use material cost.
Additionally providing the cold-heading molding technique of a kind of above-mentioned bicycle club in the present invention, it comprises the following steps that
A, by wire rod biscuit uncoiling and alignment, and shear material by circle and obtain the blank of Len req, deliver to disclose material work step, disclose material
Blank part in the hole that circle is cut is disclosed circle and is cut end face by bar, and clamp also delivers to following step b；
Gained blank in b, shaping step a, and a side end of blank is pre-upset, clamp also delivers to following step c；
C, gained blank in step b being carried out further jumping-up, and hole is drawn in upsetting on the end face of this side end, clamp is also delivered to down
State step d；
D, by gained blank backward extrusion hole in step c, clamp also delivers to following step e；
E, gained blank backward extrusion in step d being added deep hole, clamp also delivers to following step f；
F, by the end side of gained blank in step e by Huff die pre-upsetting bulb, clamp also delivers to following step g；
G, by gained blank in step f by Huff die further upsetting bulb.
Mentioned in above-mentioned cut material, shaping and backward extrusion, be all the cold pier molding skill of routine for it is each independent
Art.Therefore applicant is described in detail above-mentioned each technology word more.
A kind of bicycle club that the present invention obtains and cold-heading molding technique thereof, the bulb part innovation on its club body
Property ground use twice upsetting bulb of Huff die to shape, and be that upsetting bulb shapes again under the situation that first cold-heading becomes hollow pipe, cold-heading
Forming technology both ensure that the high intensity of product, is greatly saved again the cost of raw material.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of bicycle club provided by the present invention；
Fig. 2 be a kind of bicycle club provided by the present invention cold-heading molding process chart.
In figure: club body 1, bulb part 2, upset portion 3, buried via hole 4.
Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings.

Rice；Hole depth is 37 meters, a diameter of 22.5 millimeters；
E, gained blank backward extrusion in step d being added deep hole, clamp also delivers to following step f；The length of blank after the processing of this step e
Degree is 225.4 millimeters, a diameter of 19 millimeters；A length of 117.6 millimeters of blank remainder, a diameter of 27.82 millimeters；Bury
Hole 4 is 152 meters deeply, a diameter of 22.4 millimeters；
F, by the end side of gained blank in step e by Huff die pre-upsetting bulb, clamp also delivers to following step g；
G, by gained blank in step f by Huff die further upsetting bulb.
