Description

Technical Field

[0001] The invention relates to the technical field of steel wire rope production equipment, in particular to a rotary powder box for steel wire production. Background Art

[0002] In the process of producing steel wire ropes, thicker steel wires need to be drawn into thinner steel wires, and then twisted and roped. In the drawing process, in order to ensure the drawing quality, wire drawing powder needs to be applied on the surface of the steel wire before drawing. The traditional operation method is to make the steel wire pass through a box storing wire drawing powder, so that the surface of the steel wire is covered with wire drawing powder. Due to the small particle size of the wire drawing powder and the long-term static storage in the storage box, the problem of compaction will occur, resulting in uneven contamination on the surface of the steel wire, resulting in insufficient lubrication when the steel wire passes through the wire drawing die, scratching the surface of the steel wire, and affecting the tensile performance of the steel wire. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a rotating powder box for steel wire production. By rotating the powder storage mechanism, the internal powder is continuously tumbled to avoid powder compaction, and the powder has two movement modes relative to the steel wire: axial pulling and rotation. This ensures that the surface of the steel wire is evenly contaminated and the drawing quality is guaranteed, which can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a rotating powder box for steel wire production, comprising a powder box and a water box which are independent of each other and fixedly installed, a core fixing mechanism being horizontally rotatably installed inside the water box, the core fixing mechanism comprising a first rotating body which is hollow inside and open at both ends, a wire drawing die being coaxially fixedly installed inside the first rotating body, a powder storage mechanism being horizontally rotatably installed inside the powder box, the powder storage mechanism comprising a second rotating body which is hollow inside and open at both ends, the second rotating body being partially coaxially nested and installed inside the first rotating body, the first rotating body and the second rotating body being able to rotate relative to each other, a powder inlet being arranged on the circumferential wall of the second rotating body outside the first rotating body, the powder inlet being connected to the hollow area inside the second rotating body.

[0005] As a preferred technical solution of the present invention, the first rotating body is hollow inside and is a stepped through hole, and a top sleeve is installed through a thread at one end of the stepped through hole away from the second rotating body, and the wire drawing die is sealed and extruded and installed between the step of the stepped through hole and the top sleeve, and a water inlet is arranged at a position corresponding to the side wall of the first rotating body and the wire drawing die, and the water inlet is connected to the cavity between the wire drawing die and the inner wall of the stepped through hole;

[0006] The outer diameter of the wire drawing die is between the major diameter and the minor diameter of the stepped through hole. Through the extrusion of the mounting and pressing sleeve, the wire drawing die is fixed to the first rotating body and can rotate synchronously. Moreover, both ends of the wire drawing die are in a sealed state, so that the inner diameter surface and the outer diameter surface of the wire drawing die are respectively in two independently sealed areas, preventing the cooling water used for cooling outside the wire drawing die from entering the inner diameter position and wetting the wire drawing powder. Additionally, by loosening the mounting and pressing sleeve, the wire drawing die can be quickly replaced.

[0007] As a preferred technical solution of the present invention, a first sprocket is coaxially and fixedly installed outside the first rotating body, and a second sprocket is coaxially and fixedly installed outside the second rotating body. The first sprocket and the second sprocket are respectively connected to an external power mechanism through chains, and the rotation speeds of the first sprocket and the second sprocket are different.

[0008] By connecting the first sprocket and the second sprocket to the external power mechanism simultaneously, due to different transmission ratios, the rotation speeds of the first sprocket and the second sprocket are different, that is, the rotation speeds of the first rotating body and the second rotating body are different, so that the two rotate relatively, and the contact positions of their insertion ends can scrape against each other, avoiding the accumulation and caking of internal powder.

[0009] As a preferred technical solution of the present invention, the powder feeding mechanism includes a fixed sleeve fixedly installed with a powder box. The second rotating body is coaxially and rotatably sleeved inside the fixed sleeve, and a funnel corresponding to the position of the powder inlet is arranged on the upper part of the fixed sleeve.

[0010] By adding powder inside the funnel, when the powder inlet rotates upwards, the powder enters the second rotating body through the powder inlet and contacts and coats the steel wire.

[0011] As a preferred technical solution of the present invention, one end of the second rotating body inserted into the first rotating body is a conical structure. The end of the conical structure contacts the end of the wire drawing die, and protrusions are arranged on the contact surface between the conical structure and the wire drawing die.

[0012] After long-term operation, due to the axial feed of the steel wire, driving the wire drawing powder to move axially forward, it will accumulate at the entrance of the wire drawing die and cause caking over time. By the rotation of the protrusions at the end of the second rotating body, the wire drawing powder will not cake here, avoiding the blockage of the wire drawing die.

[0013] As a preferred technical solution of the present invention, the part of the second rotating body inserted into the first rotating body is a conical structure. A spiral guide groove is arranged on the circumferential outer wall of the conical structure, and a spiral scraping head is coaxially and fixedly arranged at the end of the conical structure. The inside of the powder box is divided into an independent powder adding bin and a powder discharging bin along the rotation axis of the second rotating body. The powder inlet is communicated with the powder adding bin, the opening of the first rotating body close to the powder box is communicated with the powder discharging bin, and a powder cleaning port is arranged at the lower end of the powder discharging bin.

[0014] By setting the spiral scraping head and the spiral guide groove, the caked wire drawing powder can be scraped off and discharged from the end opening of the first rotating body through the spiral guide groove, avoiding the long-term accumulation of the soiled wire drawing powder at the entrance of the wire drawing die.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The rotating powder box for steel wire production of the present invention adopts a rotating powder storage mechanism, making the wire drawing powder in the drawing process in a continuous flipping state, effectively avoiding the caking problem of the wire drawing powder after long-term static placement. Moreover, the wire drawing powder has an additional movement mode of axial flipping relative to the steel wire, increasing the contact probability between the wire drawing powder and the surface of the steel wire, thereby ensuring the uniform coating of the wire drawing powder on the surface of the steel wire, ensuring the lubricity when the steel wire passes through the inner hole of the wire drawing die, thus avoiding scratches on the surface of the steel wire and ensuring the drawing quality.

DETAILED DESCRIPTION OF THE INVENTION

[0024] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1:

[0026] Please refer to Figures 1-5 , the present invention provides a technical solution: a rotary powder box for steel wire production, including a powder box 1 and a water box 2 that are independently and fixedly installed. A die core fixing mechanism 3 is horizontally rotatably installed inside the water box 2. The die core fixing mechanism 3 includes a first rotating body 301 that is hollow inside and open at both ends. A wire drawing die is coaxially and fixedly installed inside the first rotating body 301. A powder storage mechanism 4 is horizontally rotatably installed inside the powder box 1. The powder storage mechanism 4 includes a second rotating body 401 that is hollow inside and open at both ends. A part of the second rotating body 401 is coaxially nested inside the first rotating body 301. The first rotating body 301 and the second rotating body 401 can rotate relative to each other. A powder inlet 403 is provided on the circumferential wall of the second rotating body 401 outside the first rotating body 301. The powder inlet 403 is communicated with the hollow area inside the second rotating body 401.

[0027] The inside of the first rotating body 301 is a stepped through hole. One end of the stepped through hole far from the second rotating body 401 is installed with a mounting top sleeve 302 by thread. The wire drawing die is hermetically squeezed and installed between the step of the stepped through hole and the mounting top sleeve. A water inlet 303 is provided at the position corresponding to the wire drawing die on the side wall of the first rotating body 301. The water inlet 303 is communicated with the cavity between the wire drawing die and the inner wall of the stepped through hole.

[0028] The outer diameter of the wire drawing die is between the large diameter and the small diameter of the stepped through hole. Through the extrusion of the mounting top sleeve 302, the wire drawing die is fixed to the first rotating body 301 and can rotate synchronously. And both ends of the wire drawing die are in a sealed state respectively, so that the inner diameter surface and the outer diameter surface of the wire drawing die are respectively in two independent sealed areas, so that the cooling water for cooling outside the wire drawing die will not enter the inner diameter position and will not wet the wire drawing powder. And by loosening the mounting top sleeve 302, the wire drawing die can be quickly replaced.

[0029] A first sprocket 304 is coaxially and fixedly installed outside the first rotating body 301, and a second sprocket 402 is coaxially and fixedly installed outside the second rotating body 401. The first sprocket 304 and the second sprocket 402 are respectively connected to an external power mechanism through chains, and the rotational speeds of the first sprocket 304 and the second sprocket 402 are different;

[0030] The first sprocket 304 and the second sprocket 402 are connected to the external power mechanism at the same time. The different transmission ratios make the rotation speeds of the first sprocket 304 and the second sprocket 402 different. Even if the rotation speeds of the first rotating body 301 and the second rotating body 401 are different, that is, they rotate relative to each other, the contact positions of the insertion ends of the two can scrape against each other to avoid internal powder accumulation and compaction.

[0031] The powder filling mechanism 5 comprises a fixed sleeve 502 fixedly mounted on the powder box 1, the second rotating body 401 is coaxially rotatably sleeved inside the fixed sleeve 502, and a funnel 501 corresponding to the position of the powder inlet 403 is arranged on the upper part of the fixed sleeve 502;

[0032] By filling the funnel 501 with powder, when the powder inlet 403 rotates to face upward, the powder enters the second rotating body 401 through the powder inlet 403 and contacts and smears the steel wire.

[0033] One end of the second rotating body 401 inserted into the first rotating body 301 is a conical structure, the end of the conical structure contacts the end of the wire drawing die, and a protrusion 404 is provided on the contact surface between the conical structure and the wire drawing die;

[0034] After long-term operation, the axial feeding of the steel wire drives the drawing powder to move axially forward and accumulate at the entrance of the drawing die, causing compaction over a long period of time. The protrusion 404 at the end of the second rotating body 401 rotates so that the drawing powder will not compact here, thus avoiding blockage of the drawing die.

[0035] When in use: the steel wire is guided by the guide mechanism, that is, passes through the common tangent position of the fixed wheel and the movable wheel, enters the second rotating body 401, then passes through the wire drawing die into the first rotating body 301, and passes out from the top sleeve 302;

[0036] During operation, power input is provided by an external power source to drive the first rotating body 301 and the second rotating body 401 to rotate at different speeds. The wire drawing powder keeps tumbling inside the second rotating body 401. When the steel wire passes through it, it contacts and smears the wire drawing powder, and then passes through the wire drawing die to change its diameter. The wire drawing die rotates with the first rotating body 301, and cooling water enters the inner hollow area of ​​the first rotating body 301 from the water inlet 303 to surround the wire drawing die, thereby achieving water cooling. Since the wire drawing die is squeezed by the top sleeve 302, the two ends of the wire drawing die are sealed to prevent cooling water from entering the inside of the wire drawing die and to prevent the wire drawing powder from getting wet.

[0037] Moreover, both sides of the first rotating body 301 and the water box 2 are installed in a rotating seal, and the cooling water inside the water box 2 will not leak. The cooling water inside the water box 2 can be circulated through an external water circulation device, thereby ensuring a constant cooling water temperature and slowing down the temperature rise of the wire drawing die.

[0038] Pour the wire drawing powder into the inside of the funnel 501. When the powder inlet 403 rotates upward and coincides with the funnel 501, the wire drawing powder enters the cavity of the second rotating body 401 under the action of gravity, completing the pouring of the wire drawing powder.

[0039] Embodiment 2:

[0040] Please refer to Figures 6-7 , the present invention provides a technical solution: a rotating powder box for wire production, including a powder box 1 and a water box 2 that are independently and fixedly installed. A die core fixing mechanism 3 is horizontally rotatably installed inside the water box 2. The die core fixing mechanism 3 includes a first rotating body 301 that is hollow inside and has openings at both ends. A wire drawing die is coaxially and fixedly installed inside the first rotating body 301. A powder storage mechanism 4 is horizontally rotatably installed inside the powder box 1. The powder storage mechanism 4 includes a second rotating body 401 that is hollow inside and has openings at both ends. A part of the second rotating body 401 is coaxially nested inside the first rotating body 301. The first rotating body 301 and the second rotating body 401 can rotate relative to each other. A powder inlet 403 is provided on the circumferential wall of the second rotating body 401 outside the first rotating body 301. The powder inlet 403 communicates with the hollow area inside the second rotating body 401.

[0041] The inside of the first rotating body 301 is a stepped through hole. One end of the stepped through hole away from the second rotating body 401 is installed with a mounting sleeve 302 through threads. The wire drawing die is hermetically squeezed and installed between the step of the stepped through hole and the mounting sleeve. A water inlet 303 is provided at the corresponding position of the side wall of the first rotating body 301 and the wire drawing die. The water inlet 303 communicates with the cavity between the wire drawing die and the inner wall of the stepped through hole.

[0042] The outer diameter of the wire drawing die is between the large diameter and the small diameter of the stepped through hole. Through the extrusion of the mounting sleeve 302, the wire drawing die is fixed to the first rotating body 301 and can rotate synchronously. And both ends of the wire drawing die are in a sealed state respectively, so that the inner diameter surface and the outer diameter surface of the wire drawing die are in two independent sealed areas respectively. The cooling water for cooling outside the wire drawing die will not enter the inner diameter position and will not wet the wire drawing powder. And by loosening the mounting sleeve 302, the wire drawing die can be quickly replaced.

[0043] A first sprocket 304 is coaxially and fixedly installed outside the first rotating body 301, and a second sprocket 402 is coaxially and fixedly installed outside the second rotating body 401. The first sprocket 304 and the second sprocket 402 are respectively connected to an external power mechanism through chains, and the rotation speeds of the first sprocket 304 and the second sprocket 402 are different;

[0044] Connect the first sprocket 304 and the second sprocket 402 to an external power mechanism simultaneously. By having different transmission ratios, the rotational speeds of the first sprocket 304 and the second sprocket 402 are made different, that is, the rotational speeds of the first rotating body 301 and the second rotating body 401 are different, which means relative rotation occurs between the two, so that the contact positions of their insertion ends can scrape against each other, avoiding the internal powder from accumulating and caking.

[0045] The part of the second rotating body 401 inserted into the first rotating body 301 has a conical structure. A spiral guide groove 406 is provided on the circumferential outer wall of the conical structure, and a spiral scraping head 405 is coaxially and fixedly provided at the end of the conical structure. Inside the powder cartridge 1, it is divided into an independent powder adding chamber 101 and a powder discharging chamber 102 along the rotation axis of the second rotating body 401. The powder inlet 403 is communicated with the powder adding chamber 101, the opening of the first rotating body 301 close to the powder cartridge 1 is communicated with the powder discharging chamber 102, and a powder cleaning port is provided at the lower end of the powder discharging chamber 102.

[0046] By providing the spiral scraping head 405 and the spiral guide groove 406, the caked wire drawing powder can be scraped off and discharged from the end opening of the first rotating body 301 through the spiral guide groove 406, avoiding the long-term accumulation of the soiled wire drawing powder at the entrance of the wire drawing die.

[0047] Compared with the first embodiment, in the second embodiment, by adding the spiral guide groove 406, the soiled wire drawing powder accumulated at the front end entrance of the wire drawing die can be discharged after being scraped off, so as to realize the continuous replacement of new powder and ensure the actual effect of the wire drawing powder.

[0048] The present invention adopts a rotating powder storage mechanism 4, making the wire drawing powder in the drawing process in a continuous flipping state, effectively avoiding the caking problem of the wire drawing powder after long-term static state. Moreover, compared with the steel wire, the wire drawing powder has an additional movement mode of axial flipping, increasing the contact probability between the wire drawing powder and the surface of the steel wire, thus ensuring the uniform coating of the wire drawing powder on the surface of the steel wire, ensuring the lubricity when the steel wire passes through the inner hole of the wire drawing die, avoiding scratches on the surface of the steel wire, and ensuring the drawing quality.

[0049] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
