Description

Technical Field

[0001] The invention relates to the technical field of metal processing, in particular to a drawing device for changing the diameter of a metal wire. Background Art

[0002] Depending on the usage scenario, metal wires of different diameters are required. Therefore, the metal wire needs to pass through a drawing device to reduce the diameter of the metal wire before use. The diameters of different metal wires are changed using a drawing device, and lubricating oil needs to be sprayed on the surface of the metal wire during the drawing process.

[0003] In the authorization announcement number CN 116727472 B, the name is a metal wire drawing device and its working method, which proposes that the oiling seal component can evenly apply lubricating oil to the outer wall of the metal wire, reducing the friction between the metal wire and the variable diameter die, and making the metal wire more evenly stressed when passing through the variable diameter die. When the tail end of the metal wire abuts against the oiling seal component, the first sealing ring and the second sealing ring can seal the outer wall of the metal wire with lubricating oil, preventing impurities from entering the variable diameter die.

[0004] The above patent uses a sealing component to limit the metal wire so that it can come into contact with the lubricating oil. However, there is still a situation where the surface glossiness of the metal wire is high, making it difficult for the lubricating oil to adhere to it. At the same time, when the metal wire passes through a hole with a small diameter, it is squeezed with the hole, making it difficult for the lubricating oil to adhere. Based on this, a new drawing equipment is proposed. Summary of the invention

[0039] The metal layer 1 32 is fixed on the bottom plate 31, and the bottom plate 31 is installed on the substrate 1. The metal layer 1 32 and the metal layer 2 33 are fixedly arranged to fit each other, which is convenient for installation and disassembly and can be cleaned.

Half of the through holes 34 are located on the metal layer 1 32, and the other half are located on the metal layer 2 33.

The two groups of sheet layers 42 are respectively located at the front and rear ends of the rotating drum 41, and the multiple sheet layers 42 are fixed to the rotating drum 41, and the multiple sheet layers 42 are distributed along the circumference of the rotating drum 41.

The upper end of the second metal layer 33 is fixed with a driving source 36, which is a servo motor. The output end of the driving source 36 is sleeved with the transmission belt 37, and the cleaning component 4 is driven to rotate through the transmission belt 37;

[0047] An oblique opening 306 is provided in the metal layer 1 32 , and the upper end of the oblique opening 306 is connected to the mounting hole 304 for the debris to fall off. The oblique opening 306 is used for receiving debris. When the cleaning component 4 moves, debris will be generated and will be received by the oblique opening 306 .

[0048] The metal layer 2 33 and the metal layer 1 32 are provided with a mounting opening 301, a receiving cavity opening 302 and a round opening 303;

[0049] The installation opening 301 and the receiving cavity opening 302 are both partially opened on the metal layer 1 32, and the other part extends upward from the metal layer 2 33. The installation opening 301 is connected with the receiving cavity opening 302. Half of the round opening 303 is located on the metal layer 2 33, and the other half is located on the metal layer 1 32. The round opening 303 is connected with the receiving cavity opening 302, and the through hole 34 passes through the installation opening 301, the receiving cavity opening 302 and the round opening 303.

[0050] The driving member 35 is installed in the installation opening 301 from top to bottom, and a sealing ring 5 is clamped in the circular opening 303. The sealing ring 5 is squeezed with the circular opening 303, and the metal wire passes through the sealing ring 5. The inner circle of the sealing ring 5 is squeezed with the metal wire to achieve a sealing effect. The sealing ring 5 is used to block the lubricating oil, and the containing cavity 302 is used to contain the lubricating oil. One side of the containing cavity 302 is blocked by the sealing ring 5, and the other side is blocked by the driving member 35. When the metal wire moves, it is equivalent to that both sides are blocked, and the lubricating oil is deposited in the containing cavity 302, which can reduce the temperature and can also be squeezed with the metal wire for lubrication.

[0051] A deformation opening 352 for the metal wire to pass through is formed on the outer side of the driving member 35. The deformation opening 352 is used for the metal wire to pass through and be squeezed to change the diameter of the metal wire.

[0052] An external opening 351 is provided on one side of the driving member 35 close to the containing cavity opening 302. The external opening 351 is coaxial with the deformation opening 352. A foam layer 353 is clamped in the external opening 351. A circumferentially arranged cutoff ring 354 is provided inside the foam layer 353. A tightening spring 355 is embedded in the cutoff ring 354. The tightening spring 355 is used to squeeze the foam layer 353 so that the foam layer 353 squeezes the metal wire. The foam layer 353 can absorb the lubricating oil, and in the process of squeezing the metal wire, the lubricating oil is applied to the metal wire so that the lubricating oil adheres to the metal wire, which can play a certain role in the pulling of the metal wire.

[0053] The outer wall of the foam layer 353 is rough, and the foam layer 353 can absorb lubricating oil. The outer side of the cut-off ring 354 of the foam layer 353 is connected to the outside. The rough foam layer 353 can be limited in the external opening 351, so that the foam layer 353 is limited. At the same time, the fastening spring 355 can be taken out in the cut-off ring 354. Wear is generated during the squeezing of the foam layer 353 and the metal wire, so the foam layer 353 can be replaced and the fastening spring 355 can be reused.

[0054] When in use, the metal wire in the winding drum 2 is passed through the pulling member 3, so that the metal wire in the winding drum 2 is pulled, and then the metal wire first passes through the cleaning component 4, and the cleaning component 4 The driving source 36 on the top is a servo motor. Under the operation of the servo motor, the rotating drum 41 is driven to rotate, and the sheet layers 42 on both sides of the rotating drum 41 are driven to rotate. Under the action of the return spring 44 and the slide plate 45, the slide plate 45 is squeezed with the outer wall of the metal wire, and the friction and squeezing effect is generated during the rotation of the slide plate 45, so as to scrape marks on the surface of the metal wire and clean the impurities on the surface of the metal wire. The lubricating oil can be stuck in the generated marks, and when squeezed by the deformation opening 352, the lubricating oil can move with the metal wire to achieve the lubrication effect. The scratches generated by the cleaning component 4 have a small friction effect during the pulling effect, and the lubricating oil provided in the scratches can enter the deformation opening 352 and move along the deformation opening 352 to achieve the lubrication effect. The diameter of the scratched metal wire changes after passing through the deformation opening 352, which still generates a relatively large friction effect. The effect of the lubricating oil can make it run more smoothly, and slight scratches are relatively difficult to affect the operation.

[0055] Secondly, when the metal wire moves through the sealing ring 5 and the deformation opening 352, the lubricating oil inside the cavity opening 302 will be blocked, and one side is the deformation opening 352. The heat generated by the extrusion of the metal wire and the deformation opening 352 can be transferred to the lubricating oil, achieving a cooling effect, avoiding deformation of the deformation opening 352 due to high temperature, and improving the accuracy of the metal wire diameter.

[0056] The foam layer 353 is provided to squeeze the metal wire, so that the metal wire moves to the front of the deformation opening 352 and is squeezed by the foam layer 353 to achieve a wiping effect. The lubricating oil absorbed by the foam layer 353 is smeared on the metal wire, so that the lubricating oil adheres to the surface of the metal wire, making the pulling process of the metal wire smoother and avoiding jamming.

[0057] The metal layer 1 32 and the metal layer 2 33 are provided to facilitate cleaning of the inside of the through hole 34 and disassembly, and the various components are easy to assemble and separate, and are better cleaned.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
