Rolling Mill Discharge Machine

The trolley of the tapping machine first automatically aligns with a certain group of slideways, and then, under the command of the PLC, the L-shaped hook lifts the slab in the heating furnace and places it stably on the roller table in front of the furnace, completing a cycle of tapping .

The operating table panel consists of three parts, namely the cart operating table, the elevator operating table and the trolley operating table.

(1) The Discharge Machine cart console. The manual and automatic operation functions of the cart can be completed on the cart console.

① Manual operation process. First, select the manual position for the “manual/automatic” switch when the normal light of the cart, the home position light of the trolley, and the home position light of the elevator are all on, and the “left travel/0/right travel” selection switch is in the “0″ position. Then select high speed or low speed as required, and finally turn the switch of “left/0/right” from “0″ to left or right, and the cart can move left or right.

②Automatic operation process. The automatic operation must first establish the zero point, and the establishment of the zero point can be established once after the cart controller is powered on. First, make sure that the cart is on the right side of lane 2. If it is not on the right side, you must manually drive to the right side of lane 2, and then drive from right to left to make the cart pass lane 2. After the proximity switch of lane 2 is activated, the lights of lane 2 are turned off. Lights up, since the zero point is established. After that, when the normal light of the cart, the home position light of the trolley and the home position light of the elevator are all on, select the “manual/automatic” switch to the “automatic” position, and finally turn the “left/middle/right” selector switch to the corresponding position. the left, middle or right position, the cart can automatically travel to the corresponding 3rd, 2nd or 1st lane and then stop automatically. Of course, when switching from manual to automatic, the current position of the “left/middle/right” selector switch is invalid. You must reselect the “left/middle/right” switch before the cart can move.
During the automatic operation of the cart, if you want to stop the automatic operation, you can turn the “manual/automatic” switch from automatic to manual.

(2) Metal Wire Drawing Machine elevator console. Includes three indicator lights and two selector switches. The indicator lights indicate the normal, fault and home position of the lift respectively. The “low speed/high speed” selector switch is used to select high and low speed when the lift is manual. The “Up/0/Down” selector switch is used to select the manual up, stop and down of the lift, respectively.

① Manual operation process. The two selector switches of the lift console are only valid in the manual state. First, turn the “manual/automatic” selector switch on the trolley console to the “manual” position, then select the “low speed” or “high speed” of the elevator as required, and finally select the “up” or “down” of the elevator as required. Turn the selector switch to “0″ when the lifting action is not required.

②Automatic operation process. The automatic operation of the elevator is automatically connected with the trolley, which is used to complete the automatic rising and falling of the L-shaped hook during the automatic tapping process.

(3) The trolley console. Includes two buttons, five indicator lights, and three selector switches. The two buttons are the “emergency stop” button and the “automatic tapping” button. The “emergency stop” button is used to cut off the power supply in an emergency to stop the trolley from running. Therefore, after the “emergency stop” button is restored, it needs to be powered on again before it can run. The indicator lights respectively indicate the normal, faulty and front position, original position and rear position of the trolley. The “manual/automatic” selector switch is used to select the manual and automatic of the trolley and the manual and automatic of the lift, the “low speed/high speed” selector switch is used to select the manual high speed and low speed of the trolley, and the “forward/0/reverse” selector switch is used to Select manual forward, stop and reverse of the trolley.

① Manual operation process. First, when the normal light of the trolley is on and the “forward/0/reverse” selector switch is in the “0″ position, turn the “manual/automatic” switch to the manual position, then select high speed or low speed as required, and finally set the “forward” The switch of /0/reverse” is turned from 0 to forward or backward, and the trolley can move forward or backward.

②Automatic operation process. For automatic operation, the origin must be established first. The trolley controller can establish the origin once every time it is powered on. The origin can be established by manually moving the trolley backward and triggering the in-situ proximity switch. At this time, the trolley’s in-position lamp is lit. Then, when the cart is aimed at lane 3, lane 2 or lane 1, and the furnace door is confirmed to be open, and the trolley normal light, trolley home position light, lift normal light and lift home position light are all on, set the ” Turn the “Manual/Auto” switch to the “Auto” position, and finally press the “Auto Tapping” button to perform automatic tapping. The action process of automatic tapping is that the trolley advances to the front position, the hoist lifts up to lift the slab, the trolley retreats to the original position, and the elevator descends so that the upper surface of the L-shaped hook is 50mm below the roller table, delay for a few seconds, and then the elevator Rise to the original position, complete a cycle, and end the automatic tapping.

In the process of automatic tapping, if you want to stop the automatic running state, you must turn the “manual/automatic” switch from “automatic” to “manual”. At this time, the unfinished trolley and elevator movements during the automatic tapping process can be stopped. Note that before turning the “manual/automatic” switch from “automatic” to “manual”, make sure that the “forward/0/reverse” switch of the trolley and the “up/0/downward” switch of the elevator must be in the “0″ position. During this process, it should be noted that in case of emergency, pressing “Emergency Stop” can only stop the operation of the trolley, but not the operation of the elevator.

Before tapping, the hydraulic system needs to work normally. First, start the hydraulic station and check whether the oil temperature, liquid level and system pressure of the hydraulic station are within the normal range. After the hydraulic system works normally for 5 minutes, the high-level tapping machine can be used.
