Description

Technical Field

[0001] The invention belongs to the technical field of nut production and processing, and in particular is a high-efficiency drawing device for high-strength nut wires. Background Art

[0002] Nut wire is the raw material for manufacturing nuts, usually wire rods or bars, mostly made of carbon steel, alloy steel or stainless steel. The diameter and mechanical properties of the wire must meet the design requirements of the nuts. In the nut manufacturing industry, the drawing process of high-strength nut wire is a key process link. The drawing process plastically deforms the metal wire through a die to reduce its diameter and increase its length, while improving the mechanical properties and surface quality of the wire. During the nut processing, the metal wire needs to be processed into a specific shape and size through a drawing process to meet the requirements of nut manufacturing. The drawing device usually includes wire release, drawing, and wire take-up. The core is to plastically deform the wire through a die to reduce its diameter, increase its length, and improve its mechanical properties.

[0003] For example, the utility model with publication number CN217044423U discloses a segmented forming device for nut wire, including a static blade, a dynamic blade, a transmission mechanism, a cutting motor, a machine table, a drawing head, a support plate, a conveyor, a flip motor and a controller, wherein the dynamic blade and the static blade are arranged in parallel one above and one below, and a plurality of dynamic sheet body incisions and static sheet body incisions are respectively provided on the same side, the cutting motor is installed on the machine table and drives the dynamic blade to move back and forth above the static blade through the transmission mechanism so that each dynamic sheet body incision and the static sheet body incision are staggered or overlapped, and a plurality of the drawing heads are respectively installed on the support plate, and the support plate is driven to flip by the flip motor, and the flip motor is driven by the conveyor to move up and down, and the drawing head includes a cylinder, an elastic clamping mechanism and a main electromagnet, and the elastic clamping mechanism includes a convex column, a torsion spring, a clamping finger and an auxiliary electromagnet, which can realize the synchronous slitting and self-release of multiple steel wires, and the cutting frequency is higher than that of a pneumatic cylinder or a hydraulic cylinder.

[0004] The existing nut pulling devices generally have the problem of wire surface damage during use. During the drawing process, severe friction is generated between the wire and the inner wall of the mold. Especially in the drawing of high-hardness wires, the friction is more significant, which can easily cause surface scratches. At the same time, the existing devices do not reasonably limit the position of the mold and the wire. During the drawing process, people need to manually control the direction of the wire. If the wire is not centered when entering the mold, it will cause excessive force on one side, aggravating surface wear.

[0005] Therefore, a high-strength nut wire efficient drawing device is proposed to solve the problems raised by the background technology. Summary of the invention

[0017] Preferably, an electric cylinder is fixedly provided at the bottom of the installation box, and the bottom of the electric cylinder is fixedly connected to the base plate.

[0018] Preferably, the lubrication mechanism includes a lubrication roller, a connecting frame fixedly arranged at both ends symmetrically at the center of the lubrication roller, an adjusting motor fixedly installed on the connecting frame for driving the lubrication roller to rotate, an adjusting component arranged on the top of the lubrication roller for adjusting the output of the lubricating oil, a movable plate fixedly arranged at both ends symmetrically of the connecting frame and two horizontal plates fixedly arranged on the movable plate, the lubrication roller is located on the top of the wire, a connecting rod is fixedly arranged on one side of the movable plate, the connecting rod is fixedly connected to the driving block, and the movable plate slides along the rectangular groove.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention facilitates the guiding effect on the wire and the mold by setting the cooperation of structures such as guide rollers, alignment rollers and drive components. The wire is placed along the mold for pulling. In order to prevent the wire from sagging and deflecting due to gravity, an alignment mechanism is used for guidance. The cooperation of guide rollers and alignment rollers ensures that the wire is aligned with the drawing hole of the mold. The drive component can quickly adjust the spacing between the guide rollers and the alignment rollers according to the length of the wire. The guide rollers and the alignment rollers are unfolded during pulling and stored after use. This solves the problem that in the existing drawing device, severe friction between the wire and the mold is easily generated during the drawing process due to insufficient lubrication and inaccurate guiding, causing damage to the surface of the wire.

[0022] The present invention facilitates the adjustment of the spacing between the rollers by setting the coordination of structures such as a fixed plate, a driving plate and a screw rod, so as to facilitate storage and unfolding. The spacing between the guide roller and the alignment roller is adjusted by the driving component. The driving motor drives the screw rod to rotate, so that the driving block moves up, and the driving plate rises accordingly. The driving groove on the driving plate pushes the limit columns away from each other, thereby expanding the spacing between the guide roller and the alignment roller, and making the measuring plate on the alignment roller close to the positioning ring. At the same time, the electric cylinder adjusts the height of the mounting box and the roller to make the measuring plate flush with the aperture of the positioning ring, supporting the wire and ensuring that the wire remains horizontal during drawing. The control motor drives the guide roller to rotate and push the wire to avoid bending and excessive friction with the mold to prevent damage.

[0023] The present invention facilitates lubrication of the surface of the drawn wire by arranging the cooperation of structures such as a lubrication roller and an adjustment component. The surface of the wire is lubricated by a lubrication mechanism. When the driving block drives the guide roller and the alignment roller to unfold, the lubrication roller synchronously moves up to the top of the wire. The adjustment component cooperates with the lubrication roller to evenly coat the lubricating oil on the surface of the wire. The adjustment motor drives the lubrication roller to rotate, and through contact with the ball, the ball is driven to roll in the adjustment port, and the lubricating oil in the storage box is discharged. The lubricating oil falls along the curvature of the lubrication roller and contacts the wire to achieve effective lubrication. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figures 1 to 10 As shown, the present invention provides a high-strength nut wire efficient drawing device, comprising a base plate 1, a die 2 fixedly arranged on the top of the base plate 1, a wire 5 passing through the inside of the die 2, and further comprising:

[0037] An alignment mechanism 3, which is located on the top of the bottom plate 1 and away from the mold 2, and is used to guide the drawn wire 5;

[0038] A lubricating mechanism 4, which is located on the top of the alignment mechanism 3 and is used to lubricate the surface of the wire 5;

[0039] Among them, the alignment mechanism 3 includes a plurality of guide rollers 31, an alignment roller 32 arranged on the side of the guide roller 31 close to the mold 2, a weighing plate 321 fixedly arranged on the outer wall of the alignment roller 32, a positioning ring 33 fixedly arranged on the side of the mold 2 close to the alignment roller 32, a rotating block 34 fixedly arranged on one end of the guide roller 31 and the alignment roller 32 respectively, a control motor 35 fixedly arranged on the end of the guide roller 31 away from the rotating block 34, and a driving component 36 arranged on the side of the guide roller 31 close to the rotating block 34 for adjusting the distance between the guide roller 31 and the alignment roller 32.

[0040] The above scheme is adopted: when in use, the wire 5 to be drawn is placed along the mold 2, and the wire 5 is drawn through the mold 2. In order to avoid the wire 5 being too long during the drawing process and being easily deflected downward by gravity during drawing, the wire 5 can be guided by utilizing the alignment mechanism 3, and the wire 5 can be aligned with the drawing hole on the mold 2 by utilizing the cooperation of multiple guide rollers 31 and alignment rollers 32. At the same time, the driving component 36 can be used to quickly adjust the spacing between the multiple guide rollers 31 and the alignment rollers 32 according to the length of the wire 5 to be drawn. When pulling is required, it can be unfolded, and it can be stored after use.

[0041] like Figure 3 to Figure 4 As shown, the driving assembly 36 includes a fixed plate 361, a driving plate 362 slidably arranged on the fixed plate 361, a circular block 363 clamped on the driving plate 362 and rotatably connected to the rotating block 34, a driving block 364 fixedly arranged on the side of the driving plate 362 away from the circular block 363, a screw 365 screwed on the driving block 364 and rotatably connected to the fixed plate 361, and a driving motor 366 fixedly arranged on the top of the screw 365, and the driving motor 366 is fixedly connected to the top of the fixed plate 361;

[0042] The fixing plate 361 is in a U shape, a vertical groove 3611 is formed on the top of the fixing plate 361, a through groove 3612 is formed on the side of the fixing plate 361 away from the annular clamping block 363, and the through groove 3612 is slidably connected to the driving block 364;

[0043] A plurality of driving grooves 3621 are provided on the surface of the driving plate 362, and the driving grooves 3621 are arranged in an umbrella shape. The interior of the driving grooves 3621 is clamped with a limiting column 3631, and the limiting column 3631 is fixedly connected to the circular block 363. An installation box 37 is provided at the bottom of the guide roller 31 and the alignment roller 32. The fixed plate 361 is fixedly connected to the installation box 37. Rectangular grooves are provided on the symmetrical sides of the installation box 37. A movable groove 371 is provided on the side of the installation box 37 away from the fixed plate 361. The guide roller 31 and the alignment roller 32 are slidably clamped in the inside of the guide roller 31 on the side away from the rotating block 34. The control motor 35 slides along the side wall of the installation box 37. An insertion rack 372 is fixedly provided on the side of the installation box 37 away from the mold. An electric cylinder 6 is fixedly provided at the bottom of the installation box 37, and the bottom of the electric cylinder 6 is fixedly connected to the bottom plate 1.

[0044] The above scheme is adopted: the humidity between the multiple guide rollers 31 and the alignment rollers 32 is adjusted by the driving assembly 36, and the screw 365 is driven to rotate by the driving motor 366, thereby driving the surface driving block 364 to move upward, and driving the driving plate 362 to move upward synchronously. Since the surface of the driving plate 362 is provided with multiple driving grooves 3621, the limiting columns 3631 engaged with the surface will be driven to move away from each other along the trend of the driving grooves 3621 during the upward movement of the driving plate 362, thereby driving the multiple guide rollers 31 and the alignment rollers 32 to move away from each other, thereby expanding the space between them. The spacing makes the measuring plate 321 on the alignment roller 32 close to the positioning ring 33, and at the same time, the electric cylinder 6 is used to adjust the height of the entire installation box 37 and the alignment roller 32 and the guide roller 31, so that the measuring plate 321 on the alignment roller 32 is flush with the aperture on the positioning ring 33, thereby supporting the wire 5, so that during the drawing process, the wire 5 can be kept in the same horizontal plane. At this time, the control motor 35 is used to drive the guide roller 31 to rotate, so as to achieve the effect of pushing the wire 5, and avoid bending, which causes greater friction between the wire 5 and the mold 2 and causes damage.

[0045] like Fig.10 As shown, the lubrication mechanism 4 includes a lubrication roller 41, a connecting frame 42 fixedly arranged at both ends of the center of the lubrication roller 41, an adjustment motor 411 fixedly installed on the connecting frame 42 for driving the lubrication roller 41 to rotate, an adjustment component 43 arranged on the top of the lubrication roller 41 for adjusting the amount of lubricating oil output, a moving plate 45 fixedly arranged at both sides of the connecting frame 42, and two cross plates 44 fixedly arranged on the moving plate 45. The lubrication roller 41 is located at the top of the wire 5. A connecting rod 46 is fixedly arranged on one side of the moving plate 45. The connecting rod 46 is fixedly connected to the driving block 364, and the moving plate 45 slides along the rectangular groove;

[0046] The adjustment assembly 43 includes a storage box 431 disposed on the top of the lubrication roller 41 and fixedly connected to the transverse plate 44 , a plurality of linearly arranged adjustment ports 432 fixedly disposed at the bottom of the storage box 431 , and a ball 433 rollingly disposed inside the adjustment port 432 .

[0047] The above scheme is adopted: lubrication of the surface of the wire 5 is achieved by utilizing the lubrication mechanism 4 to avoid damage to the wire 5 caused by friction during the drawing process. When the driving block 364 is used to drive the guide roller 31 and the alignment roller 32 to unfold, the lubrication roller 41 will be driven to move upward to the top of the wire 5 at the same time. At this time, the adjustment component 43 and the lubrication roller 41 are used in coordination to achieve the effect of continuously pouring lubricating oil onto the wire 5. The lubrication roller 41 is driven to rotate by the adjustment motor 411. Since the lubrication roller 41 is in contact with the ball 433, the ball 433 will be driven to roll in the adjustment port 432 during the rotation of the lubrication roller 41, and the lubricating oil in the storage box 431 will be continuously poured out, and fall through the arc of the lubrication roller 41, and also contact with the wire 5, so as to achieve the lubrication effect and avoid the problem of lubricating oil waste caused by direct spraying.

[0048] The working principle and use process of the present invention are as follows: when using the device, first start the driving motor 366 to drive the screw 365 to rotate, thereby pushing the driving block 364 to move, and the driving block 364 drives the driving plate 362 to slide upward along the vertical groove 3611, so that the limiting column 3631 and the circular block 363 are separated from each other. During this process, the central axes of the guide roller 31 and the alignment roller 32 slide along the moving groove 371, thereby adjusting the distance between the two. Subsequently, the guide roller 31 is lifted to rotate it, driving the circular block 363 and the rotating block 34 to rotate synchronously, completing the transmission of the wire 5, placing the wire 5 on the insertion rack 372, feeding it through the guide roller 31, and cooperating with the mold 2 to complete the drawing operation. During the drawing process, the ball 433 rolls in contact with the lubrication roller 41, and the lubricating liquid in the storage box 431 is evenly discharged and coated on the surface of the lubrication roller 41 and the wire 5, ensuring a reasonable lubrication effect while avoiding waste of lubricating liquid.
