Description

Round steel conveying and feeding device
Technical Field
The invention belongs to the technical field of supporting facilities of a steel ball processing machine, and particularly relates to a round steel conveying and feeding device.
Background
The method is that a medium frequency heating furnace (usually called as an intermediate frequency furnace for short, the same is used below) is used for heating round steel to about 1100 ℃, and then a ball forming machine (conventionally called as a ball rolling machine) is used for processing the heated round steel into steel balls, quenching and tempering the steel balls. Specifically, round steel is conveyed into the intermediate frequency furnace one by a round steel conveying mechanism on a round steel conveying rack, and then the round steel is discharged from the intermediate frequency furnace and enters the ball rolling machine. According to the professional common knowledge, round steel gradually enters the intermediate frequency furnace, gradually exits the intermediate frequency furnace and enters the ball rolling machine, that is, the whole lengthy round steel does not enter the ball rolling machine to be rolled into a steel ball after all round steel exits the intermediate frequency furnace, but heating and ball rolling are consistent. For example, the middle part of the round steel is still heated in the intermediate frequency furnace, one end of the round steel is heated and gradually enters the ball rolling machine, and the other end of the round steel is not heated in the intermediate frequency furnace, so that the round steel is fed in and discharged out while being heated and is rolled. The length of the round steel is generally 6m, and the straightness of the round steel is within 5 per thousand according to the national standard requirement. However, for round steel with a small diameter, the bending is obvious due to the large length-diameter ratio difference, and particularly, part of the round steel is easy to bend to different degrees in the transportation and hoisting process in the logistics link. The round steel with bending flaws is more obvious after being heated, so that the round steel cannot smoothly enter a ball rolling machine or a similar ball rolling machine from a round steel inlet of the ball rolling machine because the round steel is skewed with a certain probability when entering the ball rolling machine, so that on one hand, the intermediate frequency furnace does not consume heating energy, and on the other hand, the ball rolling machine is in an idling state or in an idle running state, and the production efficiency of steel balls is influenced. The current solutions are: after the condition is found, manual intervention is carried out by a person on duty to handle an iron bar or a similar tool, such as poking or poking the end of the round steel, so that the end of the round steel enters from the round steel inlet of the ball rolling machine. Although the end part, namely the head part, of the round steel can enter the inlet of the ball rolling machine, namely the round steel inlet, the production pause is objectively generated, the pause can influence the temperature of the round steel and finally influence the ball forming quality of the ball rolling machine, and the temperature of the round steel is too low, so that the ball rolling machine equipment such as a ball rolling roller and the like can be damaged. In addition, manual intervention objectively increases the working strength of operators and has potential safety hazard when the round steel at high temperature is manually intervened. Therefore, how to make the round steel conveyor can force the round steel to accurately introduce the problem of the round steel entry of the ball rolling machine for a long time to puzzle in the industry on the premise of not losing the conventional round steel conveying function to the heating furnace, and the technical scheme to be introduced below is produced under the background.
