[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1

[0028] As Figures 1 - 4 shown;

[0029] A strand drawing device, including a frame 1.

[0030] In this embodiment: It is found that the publication (announcement) number: CN210387017 discloses a wire drawing pretreatment device for strand production. In this technology, it is disclosed that "a wire drawing pretreatment device for strand production, including a cleaning table board, a sleeve fixedly connected to the cleaning table board, a fine scraping die, a lubricating powder injection pipe, and a sizing die are arranged in the sleeve from left to right in sequence, and a wire is slidably connected in the sleeve" and other technical contents, and it is disclosed that this wire drawing pretreatment device for strand production can drive the rotation of the central rotating rod and the brush wheel cylinder through a driving motor, so that the brush wheel cylinder cleans the metal debris and sundries adhered to the wire, reducing the influence on the wire surface during the wire drawing process of the wire adhered with sundries and other technical effects.

[0031] When the existing strand stops drawing, the strand will rebound, which easily causes the strand to become loose and then get entangled, and it is easy for the strand to get entangled and twisted together when it is drawn again, and it cannot be pressed when the strand stops drawing. Considering the actual use, this problem is obviously a real and relatively difficult problem to solve. In view of this, in order to solve this technical problem, a pressing component 2 and a lubricating component 3 are added to this application document.

[0032] According to the above content, in order to be able to press the strand and avoid the strand from loosening during drawing, it further includes a pressing component 2 installed on one side surface of the frame 1; the pressing component 2 includes a winding drum 201 rotatably connected in the frame 1, a fixed frame 202 installed on one side surface of the frame 1, and a U-shaped positioning frame 203 arranged below the frame 1. A hydraulic rod 204 is installed on one side surface of the fixed frame 202, a U-shaped pressing frame 205 is installed at the extending end of the hydraulic rod 204, a V-shaped guiding frame 207 is slidably connected in the pressing frame 205, a rotating rod 209 is installed on the bottom surface of the guiding frame 207, the rotating rod 209 is rotatably connected to the fixed frame 202, and two limiting wheels 210 are rotatably connected to the adjacent side surfaces of the two rotating rods 209 and below the fixed frame 202.

[0033] In this embodiment: When the strand is being drawn, the winding drum 201 pulls the strand. In order to prevent the strand from rebounding and bending during pulling, the hydraulic rod 204 on the fixed frame 202 pushes the pressing frame 205, so that the pressing frame 205 pushes the guiding frame 207, thereby driving the rotating rod 209 to rotate below the fixed frame 202 by the guiding frame 207, so that the two limiting wheels 210 on the rotating rod 209 and the fixed frame 202 press the strand, avoiding the strand from loosening and rebounding and becoming loose.

[0034] In an alternative embodiment: A torsion spring 211 is sleeved on the outer surface of the rotating shaft of the rotating rod 209. One end of the torsion spring 211 is connected to the fixed frame 202, and the other end of the torsion spring 211 is installed on the outer surface of the rotating rod 209.

[0035] In this embodiment: The torsion spring 211 always maintains an upward force, enabling the torsion spring 211 to control the angle between the rotating rod 209 and one of the limiting wheels 210, and pressing the steel strand.

[0036] In an alternative embodiment: Two rollers 206 are rotatably connected inside the pressing frame 205, and the rollers 206 are rotatably connected to the outer surface of the guiding frame 207.

[0037] In this embodiment: The two rollers 206 can reduce the wear between the pressing frame 205 and the guiding frame 207, and improve the sliding effect at the same time.

[0038] In an alternative embodiment: A top wheel 208 is rotatably connected inside the positioning frame 203, and the top wheel 208 is rotatably connected to the limiting wheel 210.

[0039] In this embodiment: The top wheel 208 can be in contact with the limiting wheel 210 below the fixed frame 202, enabling the top wheel 208 and the limiting wheel 210 to form an enclosing effect, and preventing the steel strand from coming off.

[0040] According to the above, in order to lubricate the steel strand, cool the steel strand, and avoid the flying of debris generated during the drawing of the steel strand, a lubrication assembly 3 is further included, which is arranged on one side surface of the frame body 1. The lubrication assembly 3 includes an oil tank 301 installed on one side surface of the frame body 1, a second hydraulic rod 302 installed on the inner top surface of the oil tank 301, and a positioning wheel 303 arranged inside the oil tank 301. Two brackets 304 are rotatably connected inside the oil tank 301, and both of the two brackets 304 are rotatably connected to the positioning wheel 303. The extending end of the second hydraulic rod 302 is installed with a push rod 305 having an I-shaped structure, and the push rod 305 is slidably connected in the chutes opened on the surfaces of the two brackets 304.

[0041] In this implementation scheme: The second hydraulic rod 302 in the oil tank 301 drives the push rod 305 to push the bracket 304, enabling the two brackets 304 to drive the positioning wheel 303 to press down, and adjusting the angle of the positioning wheel 303 at the same time, so that the positioning wheel 303 pulls the steel strand into the lubricating oil below the oil tank 301 to lubricate the steel strand, and avoiding problems such as overheating and debris flying out during the pulling process.

[0042] In an alternative embodiment: A roller 306 is rotatably connected in a U-shaped groove opened on one side surface of the oil tank 301.

[0043] In this embodiment, the roller 306 can avoid wear caused by contact with the steel strand and prevent damage to the fuel tank 301 at the same time.

[0044] The working principle and usage process of the present utility model are as follows: When the steel strand is being drawn, the take-up reel 201 pulls the steel strand. To prevent the steel strand from rebounding and bending during the pulling process, the limit wheel 210 on the fixing frame 202 can always be in contact with the steel strand to avoid deviation of the steel strand. The hydraulic rod 204 on the fixing frame 202 pushes the lower pressing frame 205, causing the lower pressing frame 205 to drive the roller 206 to push the guiding frame 207. As a result, the guiding frame 207 drives the rotating rod 209 to rotate below the fixing frame 202 and twist the torsion spring 211, so that the rotating rod 209 and the two limit wheels 210 on the fixing frame 202 press the steel strand to avoid loosening and rebounding of the steel strand. The hydraulic rod 302 in the fuel tank 301 drives the push rod 305 to push the support 304, causing the two supports 304 to drive the positioning wheel 303 to press down, and at the same time adjusting the angle of the positioning wheel 303, so that the positioning wheel 303 pulls the steel strand into the lubricating oil below the fuel tank 301 to lubricate the steel strand and avoid problems such as overheating and flying debris during the pulling process.

[0045] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
