Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a feeding device for a tempering furnace for spring processing. Background Art

[0002] The tempering furnace is used for tempering general metal parts in air, as well as quenching, annealing and aging heat treatment of light alloy parts such as aluminum alloy die-castings, pistons, and aluminum plates. The outer shell is welded by steel plates and steel sections, and the trolley is welded by steel sections and steel plates. The trolley reduces heat radiation and convection losses through soft contact with the furnace lining and sand sealing mechanism, effectively ensuring the sealing of the furnace body.

[0003] Prior art, such as Chinese Patent Publication No. CN211495579U, discloses a loading device for a spring processing tempering furnace, comprising a mounting plate with two first vertical plates fixedly mounted on the top of the mounting plate, and a drive motor fixedly mounted on the back of the front first vertical plates. This loading device for a spring processing tempering furnace, by providing a drive motor, a buzzer alarm, and a controller, places springs to be fed into the tempering furnace on a conveyor belt. The drive motor drives the conveyor belt to feed the springs into a material storage box. When the weight of the springs in the material storage box reaches a preset value of the controller, the controller stops the drive motor, and a loading push rod raises the material storage box to the height of the tempering furnace. When the weight of the springs in the material storage box exceeds the preset value of the controller, the controller activates the buzzer alarm.

[0004] The above device has the following deficiencies:

[0005] 1. The above-mentioned device uniformly transports the springs to be processed to the material storage box via a conveyor track. The springs in the material storage box will be entangled, which hinders the effective release of residual stress during the tempering process, which may have an adverse effect on the fatigue and creep properties of the springs.

[0006] 2. The above device ignores the strong pressing treatment after the tempering process. The springs after tempering need to be manually transferred for strong pressing treatment. This method requires high labor costs and is relatively inefficient, increasing production costs. Utility Model Content
