Description

Whole sensor that tempers of mountain bike rear axle

Technical Field

The utility model relates to a tempering inductor, concretely relates to whole tempering inductor of mountain bike rear axle.

Background

At present, mountain bicycles gradually develop towards specialization and high-end, so that higher requirements are put on parts on the bicycles. The rear middle axle as the main transmission and bearing axle of mountain bike has higher hardness, strength, wear resistance and longer service life, so it needs to be carburized and quenched. The thread parts at two ends are required to bear certain impact strength and toughness, and the common practice is to coat impermeable coating on the thread parts at two ends, so that the efficiency is low, the process is unstable, and the environment can be polluted. And after the whole carburization, induction tempering is used for the threaded parts at the two ends, so that the hardness of the threaded surface is reduced, and the hardness of the core part is ensured, thereby obtaining better toughness and strength.

The heating body of the existing tempering inductor is in a pipe shape, and when the rear center shaft is heated, the diameters of two ends of the rear center shaft are different, so that the integral tempering of the rear center shaft is not uniform, and the production efficiency is reduced.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Referring to fig. 1 and 2, the utility model provides a whole tempering inductor of mountain bike rear axle, it includes base 100 and heating member 200, and base 100 is connected fixedly with the lathe, and the export of base 100 is through the access connection of first wire 300 and heating member 200 that converges, and the export of heating member 200 is through the access connection of second wire and base 100 that converges.

The cooling water can enter the first bus bar 300 through the base 100, enter the heating body 200 through the first bus bar 300, and then enter the base 100 through the second bus bar, so as to complete the cooling of the whole inductor.

In addition, a high frequency current may enter the first bus bar 300 through the base 100, and the first bus bar 300 may transmit the high frequency current to the heating body 200, and the heating body 200 may heat the rear axle 400 of the mountain bike after being heated.

The heating body 200 specifically comprises a first lead 210 and a second lead 220, the first lead 210 is connected with the second lead 220 in series, the diameter of the first lead 210 is smaller than that of the second lead 220, the first lead 210 is connected with the small-diameter part (head) of the rear axle 400 of the mountain bike in a matching way, the second lead 220 is connected with the large-diameter part (tail) of the rear axle 400 of the mountain bike in a matching way, so that two parts with different diameters on the heating part of the rear axle 400 of the mountain bike are respectively heated through the first lead 210 and the second lead 220, the heating uniformity can be ensured, the tempering quality is improved, and the production efficiency is improved.

First wire 210 includes first copper pipe, and first copper pipe forms three diameters the same through the coiling, and concentric first ring 211, and second wire 220 includes the second copper pipe, the second copper pipe forms two diameters the same through the coiling, and concentric second ring 221, and these three first ring 211 and two second rings 221 establish ties in proper order, and the diameter of second ring 221 is greater than first ring 211, and the second ring 221 that is located terminal converges with the second and is connected, and the second ring that is located the top is connected with the first ring 211 that is located terminal, and the first ring 211 that is located the top is connected with first wire 300 that converges, like this, can guarantee that the position that two diameters are different on mountain bike rear axle 400 carries out the even heating, greatly reduced manufacturing cost again.

In order to improve the heating efficiency, the first copper pipe and the second copper pipe are both specifically copper pipes.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
