Embodiment

[0051] combine Figure 4 As shown, the process flow of the precision thermal processing method of the electromagnetic brake and clutch flange-type yoke in this embodiment includes blanking, upsetting, upsetting and extruding preforming, punching inner holes, precision extrusion molding and shaping. Glitches and other steps.

[0052] Specifically, the steps of the precision thermal processing method of the electromagnetic brake and clutch flange-type yoke in this embodiment are as follows:

[0053] Step S01, round billet heating: After the brake and clutch yoke soft magnet round billets are accurately cut, the forging temperature of the soft magnet round billets is controlled within the hot forging temperature range by intermediate frequency induction heating, and the hot forging temperature is 1100-1200 ℃; It is worth noting that the material of the round billet can be any kind of soft magnetic metal material, and low carbon steel round billet can also be used for blanking. ...

Abstract

The invention discloses a flange type magnet yoke precision hot working method for an electromagnetic brake clutch and a die, and belongs to the technical field of metal material plastic working. Theprecision hot working method comprises the following steps of S01, heating a round billet; S02, pre-forming a combined process, wherein, the first step is an upsetting process, the second step is a pre-upsetting forming process, and the third step is a punching process; S03, carrying out the closed precision extrusion forming; and S04, shaping and deburring. According to the process, forging is used for replacing casting, the magnetic conductivity of the electromagnetic brake and the clutch magnet yoke is improved, and the use requirement is better met; and the size of a forge piece is close to that of a finished product, and the material utilization reaches 98% or above. The related die comprises an upper extrusion female die, a lower extrusion female die and an extrusion male die, the space formed by the butt joint and closing of the upper extrusion female die and the lower extrusion female die is a cavity, a single-ring-shaped boss is arranged at the lower end of the extrusion maledie, and the size of the cavity is equal to the sum of the size of a magnet yoke blank and the size of the portion, stretching into the cavity, of the extrusion male die.

Description

technical field [0001] The invention belongs to the technical field of plastic processing of metal materials, and more specifically relates to a precision thermal processing method and mold of a flange-type magnetic yoke for an electromagnetic brake clutch. Background technique [0002] Flange-type yokes for electromagnetic brakes and clutches are the most important basic structural parts and core components of brakes and clutches. The structure of the product is a disc-shaped part. Specifically, its geometric feature is that there is a through hole in the middle and a The boss formed by the annular groove, the boss and the bottom flange are integrated to form a disc hub part with flange steps, and the outer ring size of the flange is larger than the outer diameter of the boss, which belongs to the disc-type axisymmetric structural part. The yoke is used as the basic part (housing) of the brake and the clutch, and is connected to other parts through the flange, and the magne...
