Description

Technical Field

[0001] The utility model relates to the technical field of metal wire processing, in particular to a stabilizing device for steel wire drawing. Background Art

[0002] Wire drawing is a metalworking process that reduces the diameter of a wire and increases its length to achieve the desired size and performance requirements by passing it through a series of drawing dies. During the drawing process, the wire is compressed and stretched as it passes through the die holes, resulting in a reduction in size.

[0003] The drawing process is widely used in the production of metal wires of various specifications. Compared with softer metal wires such as copper wire and aluminum wire, steel wire has a higher hardness, so stability control during the drawing process is particularly important. If the stability is insufficient, it will directly affect the drawing efficiency of the steel wire. It is easy to cause local defects such as scratches and pits on the surface of the steel wire under conditions of high drawing speeds. In severe cases, wire breakage may even occur, seriously affecting product quality and production efficiency. Based on the above reasons, in order to improve the drawing quality of the steel wire, the steel wire needs to be smoothly and accurately introduced into the drawing die at a higher drawing speed and kept centered, so as to ensure the stability of the steel wire during the drawing process.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0022] See also Figure 1 A preferred embodiment of a stabilizing device for steel wire drawing is disclosed. In this embodiment, the stabilizing device comprises a combined structure, which is used to guide, control tension, and enhance stability of a steel wire (1) to be drawn, ultimately guiding it into a wire drawing die for drawing. The device is integrally installed at the front end of the drawing line, ensuring that the steel wire (1) reaches optimal condition before entering the drawing die.

[0023] In this embodiment, the stabilizing device includes a fixed frame 7 serving as a base structure. The stabilizing device is assembled to the equipment frame via the fixed frame 7 and ensures the stability and accuracy of the structural components on the fixed frame 7. A guide seat 2, a clamping sleeve 8, and a die seat 12 are sequentially arranged on the fixed frame 7 along the feed direction of the steel wire 1. The clamping sleeve 8 and die seat 12 are fixed in position, while the guide seat 2 can be moved by a guide rail 6 provided on the fixed frame 7 to adjust the spacing between the guide seat 2 and the clamping sleeve 8, thereby adapting to steel wires 1 of different lengths, diameters, pulling forces, and pulling speeds.

[0024] The lower portion of the guide seat 2 is mounted on a turntable 4 via a vertical rod 3, and is secured to a guide seat 5 via the turntable 4. The turntable 4 allows the guide seat 2 to rotate freely within a plane, allowing for adjustment according to the wire feed direction. The guide seat 2 is provided with an arc-shaped guide groove, the opening width of which is slightly larger than the diameter of the wire 1. This ensures that the wire 1 remains stably within the guide groove during the guiding process, while allowing for a certain amount of fine-tuning space within the guide groove to accommodate slight deviations of the wire 1 during the drawing process.

[0025] A guide slide that matches the guide rail 6 is formed at the lower part of the guide seat 5 to achieve smooth movement of the guide seat 2 on the guide rail 6. An adjustment seat is also provided on the turntable 4 of the guide seat 2. The adjustment seat can be used to preset the angular orientation of the guide seat 2. At the same time, a torsion spring with adjustable poundage is also configured in the turntable 4. The torsion spring applies a certain rotational force to the guide seat 2 to ensure that the guide seat 2 corrects the deflection angle during the feeding process of the steel wire 1, thereby adapting to the feeding requirements of steel wires with different offset angles, reducing the vibration of the steel wire 1 during the feeding process, and ensuring stability during the guiding process.

[0026] The steel wire 1 first passes through the guide seat 2, and the guide groove on the guide seat 2 provides preliminary guidance to the steel wire to ensure that the direction thereof is correct before it enters the clamping sleeve 8.

[0027] The clamping sleeve 8 is located between the guide seat 2 and the die seat 12. The inner wall of its cylindrical channel is smooth, and the inner diameter continuously decreases along the feeding direction of the steel wire 1, forming a gradually shrinking cylindrical channel. The cylindrical channel is used to guide the steel wire 1 when it passes through; the inner wall of the cylindrical channel is finely polished to ensure a smooth surface and reduce friction of the steel wire 1 when it passes through. The clamping sleeve 8 is provided with two arc-shaped outer baffles 9 on the outlet side of the cylindrical channel. The two arc-shaped outer baffles 9 are arranged opposite to each other up and down, and the inner side thereof has a channel matching the wire diameter of the steel wire 1. The inner wall of the channel part is also finely polished to ensure a smooth surface; the outer sides of the two arc-shaped outer baffles 9 are conical cylindrical surfaces, and a clamping nut 10 is mounted thereon. The clamping force of the steel wire 1 can be adjusted by rotating the clamping nut 10, thereby accurately controlling the wire tension of the steel wire 1; specifically, by loosening the clamping nut 10 to the right, the channel size between the two arc-shaped outer baffles 9 can be enlarged, thereby reducing or even eliminating the resistance of the steel wire 1 when passing through, and when the clamping nut 10 is tightened to the left, the two arc-shaped outer baffles 9 can be clamped, thereby enlarging the channel size between the two arc-shaped outer baffles 9 and increasing the resistance of the steel wire 1 when passing through, thereby achieving tension control. This design not only ensures the stability of the steel wire 1 during the drawing process, but also can adapt to steel wires 1 of different diameters and materials.

[0028] A wire drawing die assembly portion is formed on the die base 12. In this embodiment, the wire drawing die assembly portion is a combination of a plug-in structure and a threaded fastening structure. The matching wire drawing die 11 is inserted into the insertion position reserved on the die base 12 on one side, and after being inserted into place, the position of the wire drawing die 11 on the die base 12 is fixed by screwing in the fastening screws 13 to tighten the position.

[0029] The steel wire 1 passes through the clamping sleeve 8 and enters the steel wire drawing die 11. At this time, the steel wire 1 has been well guided and has tension controlled, so it can maintain high straightness and stability during the drawing process. The design of the drawing hole inside the steel wire drawing die 11 refers to the existing steel wire drawing die in the prior art, and those skilled in the art can select and apply it according to specific needs. The drawing hole diameter of the steel wire drawing die 11 is smaller than the original diameter of the steel wire 1. Through the drawing action of the die, the diameter of the steel wire 1 is reduced and the length is increased. During the drawing process, the tension applied to the steel wire 1 is precisely controlled by the clamping sleeve 8, ensuring the smooth progress of the drawing process, thereby further improving the efficiency and quality of the drawing of the steel wire 1, and can also effectively reduce the damage and defects on the surface of the steel wire 1 during the drawing process.

[0030] In another embodiment, the tightness of the clamping nut 10 on the clamping sleeve 8 is adjusted by a threaded screw structure driven by a motor. At the same time, a tension sensor is provided on the clamping sleeve, and the tension sensor is communicatively connected to the controller; it is used to monitor the tension state of the steel wire 1 in real time through the tension sensor. The controller automatically adjusts the threaded screw driven by the motor according to the data provided by the tension sensor through a preset control algorithm, thereby achieving precise control of the clamping nut 10, thereby maintaining the stability of the tension of the steel wire 1 during the drawing process, preventing the steel wire 1 from experiencing tension fluctuations during the drawing process, and thus causing surface defects or breakage; this automatic adjustment mechanism not only improves the convenience of operation, but also greatly improves the accuracy and efficiency of the steel wire drawing process.

[0031] A pulling force detection device is typically installed at the rear end of the wire drawing die 11. This device monitors the force changes during the drawing process in real time and, through communication with a controller, allows for real-time adjustment and control of the pulling force. If an abnormal pulling force is detected, the controller automatically adjusts the motor speed or the clamping force of the clamping sleeve 8 to ensure a smooth drawing process.

[0032] In addition, to further improve the efficiency and quality of wire drawing, this embodiment can also be equipped with an automatic lubrication system. This system can spray an appropriate amount of lubricant onto the surface of the cavity structure of the guide seat 2 and the clamping sleeve 8 through a nozzle before the steel wire 1 enters the guide seat 2 and the clamping sleeve 8. The use of lubricant can significantly reduce the friction between the steel wire 1 and the clamping sleeve 8 and the wire drawing die 11, reducing wear and extending the service life of the clamping sleeve 8 and the wire drawing die 11. It also further improves the surface quality of the steel wire 1 and the stability and efficiency of the wire drawing.

[0033] In this embodiment, preferably, the distance between the die base 12 and the clamping sleeve 8 is not greater than 30 mm, and the distance between the clamping sleeve 8 and the guide seat 2 is 1.5 to 2 times the distance between the clamping sleeve and the die base, so as to ensure the stability of the steel wire 1 when passing through the clamping sleeve 8 and the wire drawing die 11.

[0034] As an optional solution, in another embodiment, an auxiliary guide structure can be provided between the guide seat 2 and the clamping sleeve 8. The guide structure is composed of two guide wheels 6 arranged opposite to each other, and the surfaces of the guide wheels 6 have guide grooves adapted to the steel wire 1. The provision of the guide structure can ensure that the steel wire 1 reduces the additional stress and potential damage caused by excessive bending of the steel wire when entering and leaving the guide wheel assembly. Such a design can ensure that the steel wire 1 has achieved a certain degree of stability and centering before entering the clamping sleeve 8, thereby maintaining a better tension state during the process of being straightened by the clamping sleeve 8 and drawn by the wire drawing die 11, reducing additional stress damage caused by inaccurate positioning of the steel wire 1.

[0035] The groove of the guide wheel 6 is designed to match the diameter of the steel wire 1 to ensure that the steel wire 1 can be accurately guided when passing. In addition, the material selection of the guide wheel 6 is preferably a wear-resistant material with a low friction coefficient, such as polyurethane or ceramic, to reduce the wear of the steel wire 1 during the guiding process.

[0036] As an optional solution, in another embodiment, the fixing frame 7 is further provided with a cleaning device before the guide seat 2 for cleaning the surface of the steel wire 1 entering the stabilizing device. The cleaning device is one or a combination of a blowing device, a cleaning brush, and a cleaning wheel to ensure that the surface of the steel wire is free of dirt and impurities before entering the guide seat, thereby reducing friction and wear during the drawing process.

[0037] In summary, this utility model achieves high efficiency and quality in the wire drawing process through precise guidance, tension control, drawing force detection, and automatic lubrication. Compared with traditional drawing technologies, this utility model not only improves the straightness and stability of the wire and reduces surface defects, but also significantly increases production efficiency and reduces production costs, showing promising application prospects and market value.
