Description

Round steel conveying and feeding device
Technical Field
The invention belongs to the technical field of supporting facilities of steel ball processing machines, and particularly relates to a round steel conveying and feeding device.
Background
The round steel is heated to about 1100 ℃ by an intermediate frequency heating furnace (generally called an intermediate frequency furnace for short), and then the heated round steel is processed into steel balls by a ball forming machine, namely a steel ball forming machine (commonly called a ball rolling machine), and quenching and tempering the steel balls are the processing modes commonly used at present. Specifically, round steel is fed into the intermediate frequency furnace in a root-by-root mode by a round steel conveying mechanism positioned on a round steel conveying rack, and is discharged from the intermediate frequency furnace to enter a ball rolling machine. According to the common general knowledge, round steel gradually enters an intermediate frequency furnace one by one and gradually goes out of the intermediate frequency furnace one by one to enter a ball rolling machine, namely, instead of the whole long round steel completely goes out of the intermediate frequency furnace and then enters the ball rolling machine to roll into steel balls, the round steel is heated and communicated with the ball rolling machine. For example, the middle part of round steel is still heated in the intermediate frequency furnace, one end is heated and gradually enters the ball rolling machine, and the other end is not yet entered in the intermediate frequency furnace, so that ball rolling is realized while entering and exiting and heating. The length of the round steel is generally 6m, and the flatness is within 5 per mill according to the national standard requirement. However, for small diameter round steel, the bending is obvious due to the great length-diameter ratio, and particularly, part of round steel is easy to bend to different degrees in the process of transportation and lifting in a logistics link. Round steel with bending flaws becomes more obvious after being heated, so that the round steel cannot smoothly enter the ball rolling machine or similar ball forming machine from a round steel inlet of the ball rolling machine due to certain probability (probability) deflection when entering the ball rolling machine, thereby not consuming heating energy for an intermediate frequency furnace on one hand, and enabling the ball rolling machine to be in an idle state or a idle state on the other hand, and influencing the production efficiency of the steel balls. The current solutions are: after the situation is found, a manual intervention is performed by a personnel handling a bar or similar tool, such as poking or poking the end of the round bar, so that the end of the round bar enters from the round bar inlet of the ball mill. Although the aforementioned manual intervention method enables the end, i.e. the head, of the round steel to enter the entry of the rolling mill, i.e. the round steel entry, production pauses have been objectively generated, which can affect the temperature of the round steel and ultimately the quality of the ball formed by the rolling mill, and too low a temperature of the round steel can also cause damage to rolling mill equipment such as the ball rolls and the like. In addition, the manual intervention objectively increases the working strength of the personnel on duty and has potential safety hazard in manual intervention on the round steel at high temperature. Therefore, the problem of how to make the round steel conveying device capable of forcing round steel to be accurately introduced into the round steel inlet of the ball rolling machine on the premise of not losing the conventional function of conveying round steel to the heating furnace has long been plagued in the industry, and the technical scheme to be described below is generated on the background.
