Description

Technical Field

[0001] The invention relates to the technical field of production and processing of fireproof cables, and in particular to a drawing device and method for production and processing of fireproof cables. Background Art

[0002] Fireproof cable refers to a cable that can slow down the spread of flames in the event of a fire, and even maintain normal operation for a certain period of time to ensure power transmission and signal transmission. Its function is to buy time for personnel evacuation, fire rescue and the operation of key equipment when a fire occurs, reduce the losses caused by the fire, and ensure the safety of life and property. The outer layer of the fireproof cable is usually wrapped with a layer of fireproof materials, such as silicates, phosphates, silicones, etc. These materials have good thermal stability, insulation and fire resistance, which can isolate the flame and prevent it from directly contacting the cable core wire. A fireproof layer is added between the conductor and the insulation layer. The materials in the fireproof layer, such as mica, have excellent fire resistance and heat resistance, and can maintain the normal operation of the cable at high temperatures, improving the reliability and safety of the cable. Fireproof cables usually use copper or aluminum. Copper has good electrical conductivity, thermal conductivity and mechanical strength, low resistance, and aluminum is light in weight and relatively low in cost. In the process of making cables, it is often necessary to draw the cables. The metal blank is pulled to pass through the die hole to obtain a plastic forming method of a product with the same size and shape as the die hole. Drawing is called drawing.

[0003] When the wire is drawn, due to the presence of dust or adhesive substances on the outside of the cable, impurities will make the friction between the metal wire and the mold complicated and intense. If the impurity particles are large or there are many of them, they may accumulate at the entrance or certain parts inside the mold, preventing the metal wire from passing through the mold smoothly, causing mold blockage, making the drawing process unable to proceed normally, and may also damage the mold structure and affect its accuracy.

[0018] 1. A drawing device and method for producing and processing fire-proof cables is provided with a guiding mechanism. When drawing the wire, the wire is first passed through the guiding groove so that the side of the wire abuts against the inner side of the guiding groove. At the same time, the side of the wire passing through the guiding groove abuts against the contact mechanism.

[0020] 3. The drawing equipment and method for producing and processing fire-proof cables are provided with a cleaning kit. When the wire continuously passes through the contact plate, the side of the wire is fully contacted and squeezed with the two sponge blocks on the cleaning shell, so that the sponge blocks can fully clean the side of the wire. At the same time, by opening the extraction mechanism, the extraction mechanism continuously sends the detergent in the storage box into the cleaning shell through the connecting pipe and flows out through the circular hole. When the wire is in contact with the sponge block for cleaning, the sponge block can mix the detergent and the wire for full contact and wiping, thereby fully cleaning the side of the wire, thereby removing impurities on the surface of the metal wire, such as dust, sand, metal debris, etc., and avoiding these impurities from rubbing against the inner wall of the mold during the drawing process, thereby effectively reducing the wear of the mold, extending the service life of the mold, and reducing the replacement frequency and cost of the mold.

When the sponge block mixed with the detergent is fully squeezed and contacted with the wire, the detergent absorbed in the sponge block will be squeezed out. By arranging a collecting box at the bottom of the contact plate and setting an inner hook arc surface at the bottom of the contact plate, when the sponge block squeezes and cleans the wire, excess detergent flowing out can flow into the collecting box through the through hole, thereby recovering the detergent flowing out and avoiding waste when cleaning the wire.

[0046] See also Fig.10 , the present invention provides a technical solution:

[0047] A drawing method for producing and processing a fireproof cable comprises the following steps:

[0048] S1: Place the metal wire on the feeding component 2, slowly lead the wire through the feeding component 2, and pass one end of the wire through the inlet connection component 7, the drawing component 5 and other equipment components in sequence, so that the wire is on the correct drawing path;

[0049] S2: Starting the drawing component 5 to draw the wire. During the drawing process, the cooling component 4 will continue to cool the drawing component 5 and the wire.

[0050] S3: After the drawn metal wire reaches the specified length and diameter, the receiving component 3 reels it and winds the drawn wire evenly and neatly on the reel.

[0051] Specific workflow:

[0052] Place the metal wire on the feeding component 2, slowly lead out the wire through the feeding component 2, and pass one end of the wire through the wire connection component 7, the drawing component 5 and other equipment components in sequence, so that the wire is in the correct drawing path to avoid damage to the wire during the threading process, and start the drawing component 5 to draw the wire. During the drawing process, the cooling component 4 will continue to cool the drawing component 5 and the wire. After the drawn metal wire reaches the specified length and diameter, it will be reeled by the receiving component 3. The receiving component 3 drives the take-up wheel to rotate through the motor, and the drawn wire is evenly and neatly wound on the take-up wheel to ensure that the wire is arranged tightly and neatly on the take-up wheel to avoid the phenomenon of random winding and stacking.

[0053] When drawing the wire, the motor drives the traction wheel 52 to rotate. The pulling force generated by the traction wheel 52 causes the metal wire to pass through the drawing die 53. Under the action of the die, the diameter of the wire gradually decreases to achieve the purpose of drawing. In this process, the drawing speed and the pulling tension must be strictly controlled according to the characteristics of the metal material and the drawing process requirements. If the metal wire needs to be drawn to a smaller diameter or higher precision, multiple drawing can be performed, that is, the wire passes through multiple drawing dies 53 with different apertures in turn, and each time it passes through a die for a certain degree of drawing, and gradually reaches the required size and performance requirements;

[0054] Before drawing the wire, the wire wound on the feeding component 2 is first passed through the guide mechanism 74. When drawing the wire, the motor 73 is turned on, and the output end of the motor 73 drives the screw rod 72 to rotate inside the workbench 1, so that the screw rod 72 drives the guide mechanism 74 to reciprocate inside the workbench 1, so that the wire on the feeding component 2 can be fed evenly and quickly.

[0055] When drawing the wire, firstly pass the wire through the guide groove 743 so that the side of the wire abuts against the inner side of the guide groove 743, and at the same time, the side of the wire passing through the guide groove 743 abuts against the contact mechanism 744, so that when the wire is feeding, the contact mechanism 744 can clean the side of the wire, thereby avoiding impurities remaining on the side of the wire when drawing the wire. The impurities will make the friction between the metal wire and the mold complicated and severe. If the impurity particles are large or there are many of them, they may accumulate at the entrance or certain parts inside the mold, preventing the metal wire from passing through the mold smoothly, causing the mold to be blocked, making the drawing process unable to proceed normally, and may also damage the mold structure and affect its accuracy.

[0056] By providing a material storage box 745 on the side of the guide plate 742, a cleaning agent is added to the material storage box 745, and by providing an extraction mechanism 747 in the connecting pipe 746, the cleaning agent in the material storage box 745 is sent to the contact mechanism 744, so that when the wire passes through the contact mechanism 744, the contact mechanism 744 can clean the side of the wire, thereby removing oil stains, rust and the like on the surface of the wire, making the surface of the wire smoother and flatter, and obtaining a better surface quality after drawing, avoiding scratches, pits and other defects on the surface, and improving the appearance quality of the wire;

[0057] When the wire is loaded and pulled, one end of the wire is passed through the groove 7444 so that the side of the wire is against the side of the rotating rod 7445, so that the side of the wire is against the cleaning kit 7448, and the wire passing through the cleaning kit 7448 continues to pass through the yield groove 7442, and at the same time, the side of the wire is against the side of the rotating plate 7443. The position of the wire is limited by setting the rotating plate 7443 and the rotating rod 7445, so that the cleaning kit 7448 can fully contact and clean the side of the wire;

[0058] When the wire continuously passes through the contact plate 7441, the side of the wire is fully contacted and squeezed with the two sponge blocks 74483 on the cleaning shell 74482, so that the sponge blocks 74483 can fully clean the side of the wire. At the same time, by opening the extraction mechanism 747, the extraction mechanism 747 continuously delivers the detergent in the storage box 745 into the cleaning shell 74482 through the connecting pipe 746, and flows out through the circular hole 74484, so that when the wire is in contact with the sponge block 74483 for cleaning, the sponge block 74483 can mix the detergent and the wire for full contact and wiping, thereby fully cleaning the side of the wire, thereby removing impurities on the surface of the metal wire, such as dust, sand, metal debris, etc., and avoiding these impurities from rubbing against the inner wall of the mold during the drawing process, thereby effectively reducing the wear of the mold, extending the service life of the mold, and reducing the replacement frequency and cost of the mold;

[0059] When the sponge block 74483 mixes the cleaning agent and the wire for sufficient extrusion contact, the cleaning agent absorbed in the sponge block 74483 will be squeezed out. By providing a collection box 7446 at the bottom of the contact plate 7441 and providing an inner hook arc surface at the bottom of the contact plate 7441, when the sponge block 74483 squeezes and cleans the wire, the excess cleaning agent that flows out can flow into the collection box 7446 through the through hole 7447, thereby recovering the cleaning agent that flows out, avoiding waste when cleaning the wire.

[0060] During the drawing process, the water pump mechanism 62 is turned on, so that the water pump mechanism 62 drives the coolant in the recovery box 61 to enter the spray mechanism 43, so that the mold and the wire are continuously cooled through the spray mechanism 43 to prevent the material properties from changing or the mold from being damaged due to frictional heat. At the same time, a filter plate 63 is provided on the top of the workbench 1, and the coolant sprayed by the spray mechanism 43 when cooling the drawing working wire can enter the recovery box 61 through the filter plate 63, so that the coolant can be recovered for easy recycling.
