Problems solved by technology

However, there are the following disadvantages in use: 1) The potentiometer for detecting the rotation angle has a high failure rate; 2) When producing wires with different specifications, it is necessary to change the counterweight or cylinder air pressure, which is not conducive to operation and management; 3) The relationship between the rotation angle and the tension There is no linear relationship, accidental results are prone to occur in control, and the reliability of operation is not high enough
The main reasons why the conical take-up reel is not used in the wire drawing machine are: 1. The users after the wire drawing and take-up are generally the next process in the wire production factory, and are not as influential as the external users of the enameled wire; 2. The existing tapered cable technology has a high cost, and the application in the wire drawing machine will excessively increase the cost of the wire drawing machine

Example Embodiment

[0068] Example one, such as Figure 5 , Image 6 Shown, with figure 1 with figure 2 The single frequency conversion wire drawing machine of the prior art shown, and image 3 with Figure 4 Compared with the structure of the double frequency conversion wire drawing machine shown in the prior art, the present invention eliminates the speed measuring device of the fixed speed wheel 11. The traditional single frequency conversion wire drawing machine needs to measure the speed of the fixed speed wheel 11 in order to obtain the slip, and the double frequency conversion wire drawing machine needs to measure the speed of the fixed speed wheel 11 to obtain the production line speed. The present invention does not need to use slip for control, and the speed measurement of the wire dividing guide wheel 1 can obtain the linear speed more accurately, so there is no need to measure the speed of the fixed speed wheel 11. Even if you want to display slip as a reference, you can use the output...

Example Embodiment

[0075] Example two, such as Picture 9 As shown, the difference between the second embodiment and the first embodiment is that the intermediate guide wheel 12 is a fixed guide wheel that is fixedly installed. Because the buffer guide wheel of the first embodiment changes suddenly in tension, the PLC control does not respond in time When it comes, it can play a buffering role, but if the control software is well designed or the PLC response is fast enough, a fixed guide wheel can be used instead of the buffer guide wheel, and the elastic swing rod device 19 can be eliminated, which can simplify the structure.

Example Embodiment

[0076] Example three, such as Picture 10 As shown, the third embodiment is different from the first embodiment in that the line dividing guide wheel 1 is located below the fixed speed wheel 11, and the intermediate guide wheel 12 is a fixed guide wheel that is fixedly installed. This structure can omit the orienting guide wheel 10. The disadvantage is that the angle of the line from the dividing guide wheel 1 to the intermediate guide wheel 12 is not fixed, and the relationship between the induction value of the dividing guide wheel tension sensor 32 and the tension of the wire is not fixed. Strict, but the impact is not great. In addition, the direction of the self-weight of the wire dividing guide wheel 1 is different from the direction of tension, which may cause inaccurate measurement, but this problem can also be solved by calibration. This structure can be used as the simplest and basic structure of the numerical control wire drawing machine of the present invention.

Abstract

The invention relates to the technical field of digitally-controlled wire drawing machines, in particular to a digitally-controlled wire drawing machine and a control method thereof. The digitally-controlled wire drawing machine comprises a middle guide wheel, a steering guide wheel, a tension sensor for a branched guide wheel and a take-up reel speed-measuring device. A capstan, the branched guide wheel and the middle guide wheel are positioned on a first routing plane; the steering guide wheel and a winding guide wheel are positioned on a second routing plane; and the first routing plane is perpendicular to the second routing plane. The reciprocating linear movement of the winding guide wheel is left-to-right movement on the second routing plane, and the winding guide wheel is positioned at the lower left of the steering guide wheel. A rotating shaft of a take-up reel is parallel to the second routing plane. In addition, in the aspect of the control of the take-up tension, the tension detection structure and the control method are changed, so that the digitally-controlled wire drawing machine is more stable, reliable and easier to operate and maintain. A ceramic wave eyelet is removed, so that the wire is not scratched.

Description

Technical field: [0001] The invention relates to the technical field of numerically controlled wire drawing machines, in particular to a numerically controlled wire drawing machine and a control method thereof. Background technique: [0002] Wire drawing machine is the basic equipment of the wire processing industry and is widely used in wire and cable related industries. The existing wire drawing machines can be divided into two categories: single frequency conversion wire drawing machines and double frequency conversion wire drawing machines. [0003] For the structure of single frequency conversion wire drawing machine see figure 1 and figure 2 As shown, the single frequency conversion wire drawing machine includes a wire dividing guide wheel 1, a fixed speed wheel 11, a buffer guide wheel, an elastic swing bar device 19, a cable rod 13, a pigtail ring 14, a cable guide wheel 15, a cable device 17 and Take-up reel 16 etc.; Its take-up tension control method is: detect...
