A feeding mechanism for a vacuum melting furnace

Abstract

The present application relates to the technical field of vacuum melting furnaces, and discloses a feeding mechanism of a vacuum melting furnace, including a melting furnace, a support shaft, a support plate, an electric push rod, a bending plate, a support tube, a cylinder, a support seat and a hub motor. When in use, the support plate can rotate relative to the support shaft under the drive of an external force, and finally multiple hub motors can move to the rod placement position or above the melting furnace charging port. By controlling the electric push rod to work, multiple hub motors can be moved to the rod placement position or the melting furnace charging port. By controlling the operation of multiple cylinders, multiple hub motors can be brought closer or separated from each other to grab or release the rods. When the rods are grabbed and moved to the melting furnace charging port, the operation of multiple hub motors can be controlled to drive the rods to move to the inside of the vacuum melting furnace. The use of rolling friction instead of sliding friction can reduce the friction between the rods and related components, thereby reducing wear and damage.

Description

Technical Field

[0001] The present application relates to the technical field of vacuum melting furnaces, for example, to a feeding mechanism of a vacuum melting furnace. Background Art

[0002] The related technology (Announcement No.: CN218210726U) discloses a feeding mechanism for a vacuum induction melting furnace, including a vacuum induction melting furnace body, a rotating bracket, a handle, a sliding rod, a mounting frame, a feeding assembly, a hydraulic pump, a supporting frame, an arc plate, an angle hydraulic rod, a notch, a hydraulic push rod, a feeding port, a fixing screw, a reinforcement frame, a round hole, a screw, a transmission gear, a limit frame, a fan gear and a transmission motor.

[0003] In the process of implementing the above embodiments, it is found that there are at least the following problems in the related art:

[0004] The feeding mechanism of the vacuum induction melting furnace, after placing the round bar into the notch of the arc plate, controls the hydraulic pump to drive the arc plate to close inward to clamp the round bar. Then controls the hydraulic push rod to push the material to move down slowly, so as to feed the material into the vacuum melting furnace.

The electric push rod is installed on the support plate along the height direction of the melting furnace, and is used to realize the linear motion function. The moving end of the electric push rod faces the melting furnace so that the driven related parts move to the location of the melting furnace. The bending plate is installed on the moving end of the electric push rod and performs linear motion under the drive of the electric push rod. The support tube is connected to the bending plate and performs linear motion under the drive of the bending plate. The cylinder is evenly installed on the support tube along the radial direction of the melting furnace, and is used to provide driving force.
