Multifunctional intelligent high-speed water tank wire drawing machine
1 Wire drawing machine composition
The multi-functional intelligent high-speed water tank wire drawing machine is a high-speed, high-efficiency and environmentally friendly intelligent production equipment designed and developed according to the needs of different wire production processes. Sexual molding. The whole machine breaks through the traditional wire drawing machine design concept and adopts multi-functional intelligent control to meet the needs of different users. The machine usually consists of three parts: pay-off machine, wire drawing machine and wire take-up machine
1.1 Pay-off machine
The design of the pay-off mechanism has various structural forms due to the different production processes of the wire manufacturers in various places. The design of the tension line accumulating mechanism is to ensure the constant tension pay-off, and at the same time consider the phenomenon of empty coil breakage during high-speed drawing. The amount should be determined according to the line speed of wire rod production.
1.2 Drawing machine
In domestic steel cord production plants, the average compression rate of wire drawing equipment is usually 14.5%, 13.4% or 13%, and the compression rate of steel wire products is 5%~10%, corresponding to 21-pass, 23-pass and 25-pass wire drawing machines. , the distribution of common intermediate drums
Usually the main body of the wire drawing machine is divided into two methods: double active drawing and one-sided passive drawing. In actual use, the two drawing methods have their own advantages and disadvantages: for double active drawing, the cooling of the die and the tower wheel adopts the immersion type. , the cooling effect is better, the threading adjustment of the whole machine is convenient, and the motor power can be fully utilized. However, since the wire needs to be drawn between the unequal diameter tower wheels, the straightness of the steel wire is poor; for unilateral passive drawing, the whole The machine adopts a fully enclosed structure, the equipment is environmentally friendly, and the noise is low. The wire is drawn by the equal-diameter pulley, the straightness of the steel wire is good, and the circle diameter is easy to control. However, because the mold and the pulley are sprayed, The cooling effect is poor, the sliding amount of the steel wire and the tower wheel is relatively large, and the power loss of the motor is relatively large. For passive drawing tower wheel, the tower wheel usually adopts an integral structure, and the whole piece needs to be replaced after a single piece is worn out, while the double active drawing tower wheel usually adopts a split type, which is convenient for maintenance and replacement. For different steel cord production processes, different drawing equipment should be selected.
1.3 I-wheel take-up machine
According to the different process needs of steel cord manufacturers, various I-shaped wheel take-up machines can be provided. The whole machine can be integrated or the wire drawing machine and the tension mechanism are connected in parallel; Top type, pneumatic double top type, etc; There are two ways of distance and equal angle. When using equal angle arrangement, it is driven by an independent servo motor, and different row distances can be set arbitrarily, and at the same time, it is synchronized with the linear speed of the main machine of the wire drawing machine. By changing accessories, a variety of spools can be used to take up wire on one wire take-up machine.
