Extrusion Management
Characteristics of extrusion management program
-
Parameters for constant velocity extrusion and isothermal extrusion can be registered, changed and searched by extrusion die unit.
-
Parameters for constant velocity extrusion and isothermal extrusion can be set in the machine.
-
You can create an extrusion schedule for each extrusion die.
-
You can also get extrusion schedules from the system's database.
-
The emissivity of the radiation thermometer can be adjusted automatically.
- Even if the extrusion speed is [m / min] of the product speed, it can be used as it is (conversion to ram speed by extrusion ratio).
-
Simulation of billet length schedule is available in 5 modes.
In extrusion management, machine parameters can be calculated for each screen and parameters can be set on machines connected to the network.
From time to time, new features are being developed.
Note>
If the machine parameter is an analog setting, you need to change it to a digital setting such as a touch panel.

Example of extrusion management program
2-1
Convert product speed to ram speed
- Program screen on the computer board.
-
In extrusion management, set extrusion speed [m / min] is converted to ram speed by extrusion ratio and constant velocity extrusion is performed. Used for companies that control extrusion speed by product speed, not ram speed.

Automate setting of ram speed
- No need to enter ram speed on the keyboard. Use mouse for ram speed input.
-
There is no need to execute the Set to Machine button. The mouse input is input to the machine as it is.

Get extrusion die schedule from factory system
-
When you execute the [Acquire Schedule] button, the [All Schedules] will display the schedule for 3 days. [Schedule] displays 10 days of the first day.
Processed extrusion dies are not displayed.
The end of extrusion die processing in the extrusion control (EM) is regarded as processed by executing the "Set in machine" button.
-
When the [Set to Machine] button is executed, the extrusion parameters of the screen are set to the machine.
-
When the [Register Database] button is executed, extrusion parameters are registered in the database.
-
When [Manual] is selected in [Control method], the worker's volume value (preset value) is output as torque (flow rate).

Extrusion management of isothermal extrusion
-
When the [Set to Machine] button is executed, the extrusion parameters of the screen are set to the machine.
-
The extrusion parameter is registered in the database by executing the [Register database] button.
Set the temperature at [Outlet temperature Low] and [Outlet temperature High].
-
When [Auto setting billet temperature] is turned on, the billet temperature is adjusted automatically. The initial value is [Set billet temperature]. The calculated billet temperature is displayed in the green Autoset Billet Temperature.
Automatic setting billet temperature is used when the rise of temperature is slow with automatic rise coefficient only.
-
[Error extrusion speed] is the tolerance of [Setting extrusion speed].
-
Error Billet Temperature is the tolerance for Set Billet Temperature.

Billet length schedule simulation
Explanation of simulation
The billet length schedule is simulated so that the extrusion billet length is constant, taking into consideration the long billet length.
Calculate billet length schedule for the order quantity.
- The maximum billet length is 565 [mm], but the first billet length is 400 [mm], so 1-1 is 400 [mm].
- The second long billet is 10 pieces for 565 [mm], 1 piece for 463 [mm], and 1 piece for 373 [mm]. It is 6500 [mm] in all.
I will use up a long billet.
- The third long billet is four 565 mm, one 361 mm, and one 373 mm. This is the end because we have scheduled billets of the order quantity.
Fig. 2-5 When calculating the billet length, set the remainder of the long billet length to 0 and use up the long billet.
