Definitions
- the present invention relates to a method for drive control a drawing machine or device and a device for pulling metallic extrudates.
- Drawing machines or devices for drawing extrudates have several drawing disks over which the continuous material, for example the wire in at least one, preferred several loops and is reduced its cross section through arranged between the drawing disks Drawing stones is pulled through.
- the drives of the pulling disks are non-slip Wire drawing machines brakes provided to turn back of the drawing disks after switching off the drawing machine to prevent.
- the present invention is therefore based on the object a method for slip-free drive control a Wet drawing machine without additional devices, such as dancers etc. with which all settings from the machine with their own regulation and the optimal operating condition can be adjusted.
- the method especially for pulling wires and Profiles made of copper, copper alloys and other special materials, which are usually pulled wet are suitable whereby an improvement in the quality of the end product is achieved shall be.
- the present invention is based on the object a device for pulling strand material of all Art, in particular also of copper, copper alloys and to create other special materials, which in slip-free Operation operated at a particularly high speed can be and which has a simple structure whereby neither touch devices, dancers or force transducers brakes are still needed.
- the total torques on the drawing disks are dependent on a number of parameters, such as. B. Forming degree, friction between wire and drawing die, drawing agent properties, drawing die polishing and mechanical and hydraulic power loss dependent.
- the total torques thus consist of the useful torques and the friction torques.
- the speeds adjust the drawing disks always the process or drawing operation on. Every change on the drawing dies is like this corrected that the disk rotation speed always is identical to the wire speed.
- the regulation of the method according to the invention is based on essential also that actual values of the torques with Reference values are compared. These reference values will be advantageously when starting the machine, which in Slip operation takes place, determined and stored. This can already after the first turns of the drawing disks take place, which is detected over the entire device Torque model to each other is saved as a machine model becomes. This machine model then serves as a reference value for slip-free operation. This ensures that the machine model remains unchanged, for what if necessary, a separate control loop is provided.
- the frictional torque of each drawing disc is dependent on of speed and automatically detected. This investigation the frictional torque occurs once in an operation without Wire and that from the motor at different speed levels between minimum and maximum speed recorded moment is recorded and saved. A So-called “friction torque characteristic" is by interpolation between the individual measured values automatically from the drive calculated so that a value for the friction torque for each speed is present.
- the present invention has a number of significant advantages compared to the prior art.
- the device can be local Changes to a specific pulling disc that speed can be corrected and cross-system changes, that do not require speed control, differentiate.
- the device or the method recognizes e.g. B. any change in deformation force due to changes in the size or quality of the incoming Wire.
- the device learns to Then independently pull the changed measurement data and submit of the new material.
- the flexibility can be increased significantly because by the control according to the invention, for example Skip drawing stages through simple self-regulating Adjusting the correct speed ratio of the successive Draw stages are carried out. This also leads to a significantly higher availability of the device, because in Repairs to a drawing stage do not affect the entire machine must be stopped.
- the smooth operation according to the inventive method is achieved in an excellent manner in that the predetermined Value of slip in stationary operation of the Drawing machine is negative. This means that the corresponding In any case, the pulling disc does not move faster turns as the wire running around them, causing wear is significantly reduced.
- the method according to the invention is outstandingly suitable Way of operating a wet drawing machine, being due the intended control different operating states from operation with slip to non-slip Operation are possible.
- Electric motors are advantageously used as drives, and everybody starts when starting the device Drive fully energized. This happens for example in chronological order from the first to the last drawing disc, after which the device starts up.
- the energization process takes place in a very short time, so that ensures is that the last pull washer first begins to turn and the preceding ones accordingly the scheme according to the invention also begin to rotate.
- the energization of the motors is advantageous controlled in such a way that the material or extrudate when stopped the machine is relaxed. With that, no brakes or other clamping devices required.
- the invention is based provided that the predetermined slip value at least for all drawing disks, the speed of which depends on the comparison value is regulated, is the same.
- the negative slip value at least -0.1%. With this Value ensures that between the pulling washer and Wire no slip occurs and stable regulation of the slip-free operation is made possible.
- the first drive in the pulling direction is particularly advantageous exempt from the regulation. This in turn leads to a stabilization of the operation because of possible fluctuations e.g. B. due to a changed diameter or changed Strength of the inlet material is therefore not taken into account stay.
- the moment the first drive changes the second drive is also determined with regard to the load balancing scheme, as is done by the Torque difference processing takes place, switched off. The change continues, due to a different Break-in resistance from the first drive to the second and via the slave drives, the control pulls the Conclusion that the changes are material, and the Speeds therefore do not need to be corrected. In order to However, it is also ensured that material changes when Welding without influencing the control of the pulling device are.
- the method according to the invention achieves that the device is self-learning, whereby a Self-optimization takes place within predetermined limits and thus an adaptation to each new inlet material takes place.
- the first torque comparison value is formed from the difference between two torques of adjacent drawing disks.
- the device according to the invention is first described below described for drawing extrudate and then the Operation of the device or the inventive Procedure described.

- Control module 33 shown for the control between the last pulling disk 7 and the pulling disk 17 are provided is.
- the torque of the puller disk 17, designated Md17, is supplied to an adder 37 via the data line 35.
- the engine torque is transmitted via a data line 39 Md7 of the drawing disk 7 is also fed to the adder 37 and in this adder 37 from the value of Md17 deducted.
- the resultant first torque difference value .DELTA.M 1 is fed to a second adder 43 according to 41 (since it is a digital drive that only works by means of software, physical data lines no longer exist from this point).
- a stored reference value ⁇ M L present in a memory 45 is compared with the value ⁇ M 1 in the adder 43. This results in a second torque difference value ⁇ M 2 .
- This is passed on appropriately filtered via a dead-range element 47 and, according to 49, meets a further addition element 51.
- the value ⁇ M 2 is compared with at least one further value, and then passed on via 53 as the drive setpoint AS.
- the drive setpoint AS is then given to a master frequency LF via further elements, which will be described later, and passed on to the drive A7 of the drawing disk 7.

Due to the curve SFK in Block 61 is started at after all drawing disks have been started a large slip, for example of the order of magnitude started from 50%, but according to the curve SFK quickly is shut down.
- the detected torque difference values ⁇ M 1 are stored in the memory 45 as reference values ⁇ M L.
- the dead zone element 47 which contains a threshold function. Only when the second torque difference value ⁇ M 2 exceeds or falls below a predetermined positive or negative threshold value is the value passed on via 49.
- the integration element 65 also serves to stabilize the control loop and is only switched when switch 59 activated to connect to block 55.
- control device will continue both the actual data extension between two neighboring ones Drawing disks 7, as well as the exact final diameter of the continuous material or wire of the drawing machine.
- This is particularly advantageous Disadvantage avoided that a larger diameter is made is because the last drawing die has a corresponding wear was subject.
- This exact determination of the final diameter the drawn wire can thus be substantial Saving costs, as only the ordered preset is regularly ordered Diameter is paid and for larger diameters and same length of wire on the spool of excess material at the expense of the wire puller.
- FIG. 4 shows a preferred alternative embodiment the control device shown.
- the main difference of the control device module 34 shown there is in the upper area of Fig. 4.
- the rest are same parts or components with the same reference numbers Mistake.
