Description

Technical Field

[0001] The utility model relates to a preheating device, in particular to a preheating device for processing a gear forging blank, belonging to the technical field of forging blank processing. Background Art

[0002] Forging is a processing method that uses a forging machine to apply pressure to a metal blank to cause it to undergo plastic deformation in order to obtain a forging blank with certain mechanical properties, a certain shape and size. Before forging, the blank needs to be preheated to increase the temperature of the blank and increase the fluidity of metal molecules, making it easier to process. The blanks for forged gears are mostly cylindrical.

Through the arrangement of an L-shaped loading plate, a heating cylinder, a controller, an electric heating coil, a second electric cylinder, a connecting rod, a baffle, a heating cylinder and a first electric cylinder, it can not only be used to preheat objects, but also when taking and placing materials, it is done on the outside of the heating box, which is not only convenient to take and place, but also the high temperature in the box is blocked during taking and placing, and will not overflow and scald the user.

[0004] The forging billet needs to be heated evenly during the preheating process. However, in the technical solution of the above-mentioned comparative document, it is impossible to ensure that the billet is in the center position of the heating tube, which will cause uneven heating of the outer surface of the billet. The forging billet is only turned over and replaced by the staff. This method not only consumes a lot of manpower, but also the staff is prone to errors when observing the preheating status of the billet with the naked eye, which affects the forging effect of the billet. In addition, the heating range of the device is limited by the length of the heating tube. Utility Model Content
