Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold steel production technology, specifically to a feeding mechanism for a vacuum tempering furnace for mold steel. Background Technology
[0002] The feeding mechanism of the vacuum tempering furnace for mold steel is a specially designed system used to feed mold steel and other workpieces into the vacuum tempering furnace for heat treatment. In use, the operator first pushes the feeding device by the handle, so that the feeding rack moves along the slide rail towards the entrance of the vacuum tempering furnace. When the feeding rack reaches the entrance of the vacuum tempering furnace, the operator places the mold steel and other workpieces on the feeding rack. Then, through the control system of the vacuum tempering furnace, the feeding rack and the workpiece are fed into the furnace together for heat treatment.
[0003] For example, Chinese patent CN221499641U, entitled "A Feeding Device for Mold Steel Plate Production," includes a base plate, which further comprises: support columns, symmetrically arranged in pairs and fixedly installed on the top surface of the base plate; a conveying frame, fixedly installed on the top of the support columns; a cover, fixedly installed on the rear side of the conveying frame; a feeding mechanism, disposed on the conveying frame, used to convey the mold steel plate; a rotating mechanism, disposed on the top surface of the base plate; and a positioning and guiding mechanism, connected to the rotating mechanism.
[0004] While the existing technology can feed mold steel into the tempering furnace, in practical use, the feeding effect of mold steel is not good enough. Usually, there is a certain gap between the feeding rack and the tempering furnace when the mold steel is put into the tempering furnace, which requires the assistance of operators to participate in the feeding of the tempering furnace, thereby reducing the feeding effect of mold steel. On the other hand, it is difficult to limit the mold steel. Usually, a drive mechanism is used to push the mold steel into the tempering furnace on the roller, which causes the mold steel to easily shift its position on the roller, thus affecting the feeding efficiency. Therefore, it does not meet the current requirements. To address this, we propose a feeding mechanism for a vacuum tempering furnace for mold steel. Utility Model Content

At this time, the mold steel is placed on one side of the feeding rack, and then the third hydraulic telescopic device is opened. The telescopic end of the third hydraulic telescopic device extends and drives the rubber pad to move, so that the rubber pad pushes the mold steel to slide between the upper limit wheels of the guide plate until the mold steel is sent into the tempering furnace, thereby improving the accuracy of mold steel feeding.
