Quenching inductor for conical pit of brake disc and matched application size determining method

Abstract

The invention discloses a quenching inductor for a conical pit of a brake disc and a matched application size determining method. The quenching inductor comprises a heating coil of the quenching inductor, a left square pipe, a right square pipe, a left round pipe and a right round pipe; the heating coil, the left square pipe, the right square pipe, the left round pipe and the right round pipe are hollow pipes; the water inlet end of the left square pipe is vertically welded with the water outlet end of the left round pipe, and the water outlet end of the left square pipe is horizontally welded with a water inlet pipe orifice of the heating coil; the water outlet end of the right square pipe is vertically welded with the water inlet end of the right round pipe, and the water inlet end of the right square pipe is horizontally welded with the water outlet pipe orifice of the heating coil; and one end of each of the left square pipe and the right square pipe communicates with the inside of the heating coil, and the other ends of the left square pipe and the right square pipe communicate with the insides of the left round pipe and the right round pipe respectively. The effective induction area is increased, and the problem that it is difficult to increase the induction heating efficiency is solved; the heating coil of the inductor is effectively coincided with the conical pit, and a gap is retained; and the heating efficiency and the depth of a hardened zone are guaranteed, and no fusing and ignition phenomena can be caused. The quenching inductor is reasonable in structure and reliable in application; and a matched application method is simple and feasible as well as easy to implement.

Description

technical field [0001] The invention belongs to the technical field of induction heat treatment, and relates to a quenching inductor used for a cone socket of a brake pressure plate and a method for determining matching dimensions. Background technique [0002] As we all know, the braking performance of tractors is an important factor that determines the safety of production operations. With the rapid development of agricultural machinery, the trend of large-scale and intelligent tractors at home and abroad has become increasingly prominent. The maximum speed of large and medium-sized tractors has exceeded 30 km / h. Therefore, it is particularly important to ensure that the braking performance of the tractor is in a safe technical state. [0003] The factor that directly determines the tractor's braking performance is the friction force between the brake pressure plate and the friction plate during braking, and the friction force depends on the friction coefficient between th...

Problems solved by technology

[0022] In order to solve the above problems, the object of the present invention is to provide a quenching inductor for the brake pressure plate cone socket and a method for determining the matching size, that is, by using a round copper tube to make a profiling induction heating ring, it solves the current problem. The "one"-shaped inductor used has poor profiling and unsatisfactory heating effects; by adopting the matching size determination method, not only the quenching inductor is easy to manufacture and easy to match, but also the quality of induction hardening can be more effectively improved control
