Description

Technical Field

[0001] This utility model relates to the field of metal wire processing equipment technology, and in particular to an oiling device for metal wires. Background Technology

[0002] Metal wire oiling involves applying a layer of oil to the surface of the metal wire to prevent damage caused by contact and friction between the wires during winding, thus effectively protecting the wire. Existing wire drawing and oiling mechanisms use spray components to continuously apply oil to the metal wire. Although this method can effectively oil the metal wire, it requires continuous spraying of drawing oil, resulting in a large consumption of oil.

[0003] A search revealed a Chinese utility model patent with authorization announcement number CN218251217U, which discloses a wire oiling mechanism for a metal wire drawing machine. In this solution, piston heads are evenly installed on the rotating wheels. When the metal wire passes between two rotating wheels, one of the piston heads is squeezed, and an appropriate amount of drawing oil will flow out of the oil outlet hole of the rotating wheel at that point to oil the metal wire, thus avoiding excessive use of drawing oil.

[0004] However, this solution has the following drawbacks: each time it is used, the oil needs to enter the inside of the rotor to fill the hollow cavity before being sprayed out from the oil outlet on the surface of the rotor. Therefore, a lot of oil will accumulate inside the rotor. When the device is not in use, the oil will remain inside the rotor for a long time. Under the action of gravity, this oil will gradually seep out from the gap between the oil outlet at the bottom of the rotor and the piston head. The oil drips onto the vicinity of the device, causing oil waste and easily polluting the site. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a metal wire oiling device to solve the technical problem that excessive oil accumulates inside the rotating wheel during the use of existing metal wire oiling devices, and the oil easily seeps out from the surface of the rotating wheel after standing.

[0006] To achieve the above objectives, this utility model provides an oiling device for metal wires, comprising:

[0007] support;

[0008] At least two hollow guide wheels are rotatably connected to the bracket, and the circumference of the guide wheels is provided with a recessed groove that matches the cross-sectional shape of the metal wire.

[0009] The flow collector housing is provided in the guide wheel;

[0010] An oil delivery pipe with one end extending into the guide wheel and connected to the collector housing;

[0011] The rotation axis of the guide wheel is arranged in a ring with several sleeves in the guide wheel. One end of the sleeve is connected to the flow collection shell, and the other end of the sleeve passes through the surface of the recessed groove and is provided with an oil injection hole.

[0012] A firing structure is provided in the sleeve to control the opening and closing of the oil injection hole, so that when the metal wire squeezes the firing structure, it causes the oil injection hole of the sleeve to open, thereby releasing the oil used to coat the metal wire.

[0013] As a preferred embodiment of this invention, the oiling device further includes:

[0014] A rotating shaft is located at one end of the guide wheel;

[0015] A slider rotatably connected to the rotating shaft, the slider slidingly engaging with a groove formed in the bracket;

[0016] A drive mechanism for controlling the adjacent sliders to move away from or towards each other.

[0017] As a preferred embodiment of this utility model, the driving mechanism includes:

[0018] A lead screw with one end passing through the slide groove and rotatably connected to the bracket, the lead screw being adapted to a lead screw groove formed on the surface of the slider;

[0019] A motor is fixedly connected to the bracket, and the output shaft of the motor is connected to a lead screw.

[0020] As a preferred embodiment of this utility model, a limiting plate is provided at one end of the rotating shaft, the rotating shaft is rotatably engaged with a rotating groove formed in the slider, the limiting plate is rotatably engaged with a groove formed in the slider, and an end cap is sleeved on the outside of the rotating shaft. The end cap is used to limit the limiting plate in the groove to prevent the rotating shaft from moving along its axial direction.

[0021] As a preferred embodiment of this utility model, the firing structure includes:

[0022] A contact that fits with the oil injection hole with a clearance;

[0023] A sealing plate is fixedly connected to the contact at one end. The sealing plate is slidably disposed in the sleeve and divides the sleeve into two chambers. A through hole for connecting the two chambers is opened at the outer extension of the sealing plate.

[0024] A retaining ring is provided in the sleeve;

[0025] An elastic element is provided between the fixing ring and the sealing plate. The elastic element is used to keep the sealing plate in contact with the inner end face of the sleeve to block the through hole.

[0026] As a preferred embodiment of this invention, the elastic element is a spring.

[0027] As a preferred embodiment of this utility model, the manifold is connected to one end of a plurality of oil inlet pipes, and the other end of the oil inlet pipes is connected to a quick connector located at one end of the sleeve.

[0028] As a preferred embodiment of this utility model, a flexible oiling ring is provided in the recessed groove of the guide wheel, and the flexible oiling ring is in contact with the oil injection hole.

[0029] As a preferred embodiment of this invention, the contact penetrates the flexible oil-coated ring.

[0030] The beneficial effects of this utility model are as follows: This utility model sets up a collecting shell inside the guide wheel. The collecting shell has good sealing performance and can replace the hollow cavity inside the guide wheel to store oil. At the same time, a sleeve is set inside the guide wheel, and an oil spray hole is opened at one end of the sleeve, which can replace the oil outlet hole on the surface of the guide wheel for oil spraying. In use, after connecting the oil supply pipe to the oil supply end of the oil supply equipment, the drawing oil enters the collecting shell through the oil supply pipe. The collecting shell sends the drawing oil into each sleeve, forming a stable oil supply pipeline, preventing the oil from accumulating too much inside the guide wheel and avoiding the oil from seeping out from the surface of the guide wheel after standing.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0038] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0039] like Figure 1 and Figure 3 As shown, an oiling device for metal wire includes: a support 1; at least two hollow guide wheels 7 rotatably connected to the support 1, each guide wheel 7 having a recessed groove on its circumference adapted to the cross-sectional shape of the metal wire; a collecting shell 13 disposed in the guide wheel 7; an oil supply pipe 12 extending into the guide wheel 7 and communicating with the collecting shell 13; a plurality of sleeves 15 arranged in a ring about the rotation axis of the guide wheel 7, each sleeve 15 having one end communicating with the collecting shell 13 and the other end penetrating the surface of the recessed groove and having an oil spray hole 17; and a firing structure disposed in the sleeve 15 for controlling the opening and closing of the oil spray hole 17, so that when the metal wire presses against the firing structure, it causes the oil spray hole 17 of the sleeve 15 to open, thereby releasing the oil used to coat the metal wire.

[0040] The above technical solution can prevent excessive oil accumulation inside the guide wheel 7, thus avoiding continuous oil seepage from the grooves on the surface of the guide wheel 7 when the device is not in use. In use, the oil supply pipe 12 is first connected to the oil supply end of the oil supply equipment, which includes an oil tank, an oil supply conduit, and a pump. The pump delivers the drawing oil from the oil tank to the oil supply pipe 12 via the oil supply conduit. The drawing oil then enters the manifold 13 through the oil supply pipe 12, and is then delivered to each sleeve 15 through the manifold 13. Since the oil injection holes 17 of the sleeves 15 are normally closed by the firing mechanism, the oil will not flow out. The manifold 13 has good sealing performance and can replace the hollow cavity inside the guide wheel 7 to store the oil. Meanwhile, a sleeve 15 is set inside the guide wheel 7, and an oil spray hole 17 is opened at one end of the sleeve 15. This can replace the oil outlet hole on the surface of the guide wheel 7 for oil spraying. The combination of the collector shell 13 and the sleeve 15 can effectively prevent the oil from seeping out from the surface of the guide wheel 7 after standing. The metal wire to be coated is passed through the recessed grooves of the two guide wheels 7. As the metal wire is fed, it will drive the guide wheel 7 to rotate. The metal wire squeezes the firing structure, causing the firing structure to open the oil spray hole 17 of the sleeve 15. The drawing oil is sprayed outward through the oil spray hole 17 under pressure, thereby releasing an appropriate amount of oil for coating the metal wire. When the metal wire is separated from the firing structure, the firing structure closes the oil spray hole 17 again to avoid excessive use of drawing oil.

[0041] like Figure 2 As shown, in this embodiment, the oiling device further includes: a rotating shaft 8 disposed at one end of the guide wheel 7; a slider 3 rotatably connected to the rotating shaft 8, an oil supply pipe 12 rotatably disposed inside the rotating shaft 8, and the slider 3 slidingly engaging with a groove 2 opened in the bracket 1; a drive mechanism for controlling adjacent sliders 3 to move away from or closer to each other; specifically, the drive mechanism includes: a lead screw 5 with one end passing through the groove 2 and rotatably connected to the bracket 1, the lead screw 5 being adapted to a lead screw groove 6 opened on the surface of the slider 3; and a motor 4 fixedly connected to the bracket 1, the output shaft of the motor 4 being connected to the lead screw 5;

[0042] The above technical solution allows for adjustment of the spacing between guide wheels 7 according to different specifications of metal wire. In use, the motor 4 is started to drive the lead screw 5 to rotate. Since the lead screw 5 is a bidirectional lead screw, it can simultaneously drive the two sliders 3 to move closer or further apart. When the two sliders 3 move further apart, the spacing between the guide wheels 7 connected to the sliders 3 increases, which is suitable for spraying metal wires with larger radii. Conversely, when the spacing between the guide wheels 7 decreases, it is suitable for spraying metal wires with smaller radii. Since the oil delivery pipe 12 is rotatably located inside the rotating shaft 8, it can prevent the oil delivery pipe 12 from rotating synchronously when the guide wheels 7 rotate, thus preventing the oil delivery pipe 12 from driving the oil delivery conduit and pump to rotate synchronously.

[0043] like Figure 2As shown, in this embodiment, a limiting plate 10 is provided at one end of the rotating shaft 8. The rotating shaft 8 is rotatably engaged with the rotating groove 9 opened in the slider 3. The limiting plate 10 is rotatably engaged with the groove opened in the slider 3. An end cap 11 is sleeved on the outside of the rotating shaft 8. The end cap 11 is used to limit the limiting plate 10 in the groove to prevent the rotating shaft 8 from moving along its axial direction.

[0044] The above technical solution allows the rotating shaft 8 to be detachably placed in the rotating groove 9 of the slider 3. When it is necessary to remove the rotating shaft 8, the end cover 11 is removed from the groove of the slider 3, and the end cover 11 releases the lock on the limiting plate 10, so that the rotating shaft 8 can be removed from the rotating groove 9 of the slider 3.

[0045] like Figure 4 As shown, in this embodiment, the firing structure includes: a contact 18 that is clearance-fitted with the oil injection hole 17; a sealing plate 19 fixedly connected to the contact 18 at one end, the sealing plate 19 being slidably disposed in the sleeve 15 and dividing the sleeve 15 into two chambers, and a through hole 20 for connecting the two chambers being provided on the outer extension of the sealing plate 19; a fixing ring 21 disposed in the sleeve 15; and an elastic member 22 disposed between the fixing ring 21 and the sealing plate 19, the elastic member 22 being used to keep the sealing plate 19 in contact with the inner end face of the sleeve 15 to block the through hole 20; preferably, the elastic member 22 is a spring;

[0046] The above technical solution enables the spraying of drawing oil after the metal wire squeezes the sleeve 15. In use, when the metal wire squeezes the contact 18, the contact 18 will drive the sealing plate 19 to retract into the sleeve 15, thereby making the through hole 20 on the surface of the sealing plate 19 open. The drawing oil is sprayed onto the surface of the metal wire through the through hole 20 and the oil spray hole 17 in sequence, thus achieving the coating of the metal wire. When the metal wire is separated from the contact 18, under the elastic action of the elastic element 22, the sealing plate 19 is reset and abuts against the inner end face of the sleeve 15 to block the through hole 20, thereby preventing the continued spraying of drawing oil.

[0047] like Figure 3 As shown, in this embodiment, the manifold 13 is connected to one end of a plurality of oil inlet pipes 14, and the other end of the oil inlet pipes 14 is connected to a quick connector 16 located at one end of the sleeve 15.

[0048] The above technical solution can connect the manifold 13 and the sleeve 15. When in use, after the drawing oil enters the manifold 13, it is sent into the sleeve 15 through the oil inlet pipe 14 on the surface of the manifold 13, thus preparing for the spraying of metal wire.

[0049] like Figure 2 and Figure 3 As shown, in this embodiment, a flexible oiling ring 23 is provided in the recessed groove of the guide wheel 7, and the flexible oiling ring 23 contacts the oil injection hole 17; the contact 18 passes through the flexible oiling ring 23.

[0050] The above technical solution can spray the metal wire more evenly. When the drawing oil is sprayed out from the oil spray hole 17, the drawing oil will first wet the flexible oiling ring 23, so that the flexible oiling ring 23 is filled with oil. Then, the flexible oiling ring 23 wraps the metal wire and applies oil to the metal wire. The flexible oiling ring 23 can be made of sponge.

[0051] Working principle: When in use, first adjust the spacing between the guide wheels 7 according to the different specifications of metal wires, place the metal wire between the guide wheels 7, start the motor 4 to drive the lead screw 5 to rotate, the lead screw 5 cooperates with the lead screw groove 6 on the surface of the slider 3, thereby driving the two sliders 3 to move closer together to squeeze the metal wire, connect the oil supply pipe 12 to the oil supply end of the oil supply equipment, and the wire drawing oil enters the collection shell 13 through the oil supply pipe 12. The collection shell 13 then sends the wire drawing oil into each sleeve 15.

[0052] Under normal conditions, the oil injection hole 17 of the sleeve 15 is closed by the sealing plate 19, so the oil will not flow out. The manifold 13 has good sealing performance and can replace the hollow cavity inside the guide wheel 7 to store oil. At the same time, the sleeve 15 is set inside the guide wheel 7, and the oil injection hole 17 is opened at one end of the sleeve 15, which can replace the oil outlet hole on the surface of the guide wheel 7 for oil injection. The manifold 13 and the sleeve 15 are combined to effectively prevent the oil from seeping out from the surface of the guide wheel 7 after standing. As the metal wire is fed in... The guide wheel 7 will rotate. When the metal wire squeezes the contact 18, the contact 18 will cause the sealing plate 19 to retract into the sleeve 15, thereby making the through hole 20 on the surface of the sealing plate 19 open. The wire drawing oil will be sprayed onto the surface of the metal wire through the through hole 20 and the oil spray hole 17 in sequence, thus achieving the coating of the metal wire. When the metal wire is separated from the contact 18, under the elastic action of the elastic element 22, the sealing plate 19 will reset and abut against the inner end face of the sleeve 15 to block the through hole 20, thereby preventing the continued spraying of wire drawing oil.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
