A steel wire processing pretreatment device

Abstract

This utility model discloses a steel wire pretreatment device, which includes a fixed frame, a rotating drum rotatably connected to the side wall of the fixed frame, two connecting plates on one side wall of the rotating drum, and a mounting frame on the other side of the connecting plates. Two grinding components are slidably connected to the inner side wall of the mounting frame, and an adjustment component is provided inside the mounting frame. In this steel wire pretreatment device, the steel wire to be ground is placed between adjacent grinding rollers. By turning on the first motor, the worm gear is driven to rotate, thereby causing the two worm wheels to rotate simultaneously, driving the two rotating shafts to rotate simultaneously, which in turn causes the grinding rollers to rotate and grind the steel wire. By turning on the second motor, the gear is driven to rotate, thereby causing the gear ring to rotate, which in turn causes the rotating drum to rotate, which in turn causes the connecting plate to drive the mounting frame to rotate. This allows multiple grinding rollers to rotate around the center of the steel wire simultaneously, which facilitates more thorough grinding of the steel wire surface and effectively improves the pretreatment efficiency. Furthermore, the adjustment component can easily accommodate steel wires of different sizes, improving the grinding effect.

Description

Technical Field

[0001] This utility model relates to the field of steel wire processing technology, specifically to a steel wire processing pretreatment device. Background Technology

[0002] Steel wire is one of the four major types of steel products: plates, tubes, profiles, and wires. It is a reprocessed product made from hot-rolled wire rods through cold drawing. During steel wire processing, it is necessary to remove iron oxide scale, which refers to removing the iron oxide scale from the surface of the wire rod or intermediate wire blank. The purpose is to prevent the iron oxide scale from damaging the die and the surface of the steel wire during drawing, to prepare good surface conditions for subsequent coating or plating treatments, and to reduce friction and drawing force during drawing.

[0003] The prior art patent document with publication number CN214642286U provides a pre-treatment device for processing steel wire for automotive springs, including a worktable. Several support columns are fixedly connected to the bottom end of the worktable. A wire feeding mechanism is respectively arranged on the left and right sides of the upper end of the worktable. Two sets of grinding mechanisms are arranged between the left and right wire feeding mechanisms. When using the wire feeding mechanism, the steel wire is passed between the first wire feeding wheel and the second wire feeding wheel. The first motor is started, and the first motor drives the first wire feeding wheel to rotate. The steel wire is automatically fed and discharged under the friction between the first wire feeding wheel and the second wire feeding wheel. The steel wire is passed between the front and rear limiting members. Under the action of the telescopic rod and the spring, the grinding sandpaper is tightly attached to the outer surface of the steel wire. The wire feeding mechanism drives the steel wire to feed, and the grinding sandpaper grinds the steel wire to make its outer surface smooth, which is convenient for subsequent processing.

[0004] Although the device has many beneficial effects, it still has the following problems: During the use of the device, it can only grind the two sides of the steel wire, which is not enough and affects the pre-treatment efficiency of the steel wire; secondly, the size of the limiting part is fixed during the use of the device, which is not convenient to adapt to steel wires of different sizes, affecting the grinding effect. It needs to be improved. In view of this, we propose a steel wire processing pre-treatment device. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the issues raised above, such as the inadequate grinding of only the two sides of the steel wire, which affects the efficiency of steel wire pretreatment, and the fixed size of the limiting component which makes it difficult to adapt to steel wires of different sizes and affects the grinding effect, this utility model is proposed.

[0008] Therefore, the purpose of this utility model is to provide a steel wire processing pretreatment device that facilitates more thorough grinding of the steel wire surface, improves the steel wire pretreatment efficiency, facilitates adjustment of the grinding roller position, adapts to steel wires of different sizes, and improves the grinding effect.

[0009] 2. Technical Solution:

[0010] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0011] A wire pretreatment device includes a fixed frame with a rotating drum rotatably connected to its side wall. Two connecting plates are located on one side wall of the rotating drum, and a mounting frame is located on the other end of each connecting plate. Two grinding components are slidably connected to the inner side wall of the mounting frame. Each grinding component includes a mounting base, with rotating shafts rotatably connected to both sides of the inner side wall of the mounting base. Grinding rollers are located on the outer circumference of each of the two rotating shafts. A protective cover is located on the side wall of the mounting base, and a first motor is located on the side wall of the protective cover. A worm gear is located at the output end of the first motor, and worm wheels fitted onto one end of the outer circumference of the rotating shaft are engaged at both ends of the outer circumference of the worm gear. A second motor is located on the side wall of the fixed frame, and a gear is located at the output end of the second motor. The gear engages with a gear ring fitted onto the other end of the outer circumference of the rotating drum. An adjustment component is located inside the mounting frame. The first and second motors are electrically connected to an external power source. The protective cover prevents dust generated during wire grinding from entering between the worm gear and worm wheel, avoiding blockage and affecting the meshing of the worm gear and worm wheel.

[0012] In a preferred embodiment of the wire processing pretreatment device of this utility model, the adjusting assembly includes two lead screws, one of which has a handle at its top. Both ends of the outer circumference of the two lead screws are threaded with sliders, the sidewalls of which are fixedly connected to the sidewalls of the mounting base. The bottom of the outer circumference of each of the two lead screws is provided with a first bevel gear, and each of the two first bevel gears meshes with a second bevel gear. The outer circumference of the two second bevel gears is provided with a rotating rod that is rotatably connected to the sidewall of the inner cavity of the mounting frame. Controlling the rotation of one lead screw causes the other lead screw to rotate simultaneously, improving operational efficiency.

[0013] In a preferred embodiment of the wire processing pretreatment device of this utility model, the top middle of the two side walls of the mounting base is concave, and the length of the second motor is less than the length of the connecting plate.

[0014] In a preferred embodiment of the wire processing pretreatment device of this utility model, the worm gear is rotatably connected to the inner wall of the protective cover, and the heights of two adjacent grinding rollers are matched. The rotatable connection between the worm gear and the inner wall of the protective cover prevents instability of the worm gear from causing it to tilt and disengage from the worm wheel.

[0015] In a preferred embodiment of the wire processing pretreatment device of this utility model, the outer wall of the rotating handle is provided with multiple striped protrusions, and the thread directions at both ends of the outer wall of the lead screw are opposite.

[0016] In a preferred embodiment of the wire processing pretreatment device of this utility model, grooves are provided on both sides of the inner cavity of the mounting frame, and the size and position of the slider match the size and position of the grooves.

[0017] In a preferred embodiment of the wire processing pretreatment device of this utility model, the bottom of the fixing frame is provided with a base, and the cross-sectional dimension of the base is larger than that of the fixing frame.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This steel wire pretreatment device places the steel wire to be ground between adjacent grinding rollers. By turning on the first motor, the worm gear rotates, causing two worm wheels to rotate simultaneously, which in turn drives two rotating shafts to rotate simultaneously. This causes the grinding rollers to rotate and grind the oxide layer on the surface of the steel wire. By turning on the second motor, the gear rotates, causing the gear ring to rotate, which in turn drives the rotating drum to rotate. This, in turn, causes the connecting plate to drive the mounting frame to rotate, making it easier for multiple grinding rollers to rotate around the center of the steel wire at the same time. This allows for more thorough grinding of the steel wire surface and effectively improves the pretreatment efficiency.

[0021] This type of wire pretreatment device rotates by turning a lever, which in turn drives a first bevel gear to rotate a second bevel gear. This, in turn, drives a rotating rod to rotate another second bevel gear. This allows both lead screws to rotate simultaneously, facilitating control and preventing jamming due to asynchronous operation. The rotation of the lead screws causes both sliders to move inward simultaneously, which in turn moves the two mounting seats inward. This allows the grinding roller to come into contact with the wire to be ground, making it suitable for different sizes of wire and improving the grinding effect. Attached Figure Description

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] This utility model is described in detail with reference to the schematic diagrams.

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of a steel wire processing pretreatment device, including:

[0035] Please see Figures 1-5 This embodiment of a steel wire processing pretreatment device includes a fixed frame 1. A rotating drum 2 is rotatably connected to the side wall of the fixed frame 1. Two connecting plates 3 are welded to one side wall of the rotating drum 2, and a mounting frame 4 is fixed to the other end of the connecting plates 3. Two grinding components 5 are slidably connected to the inner side wall of the mounting frame 4. The grinding components 5 include a mounting base 501. Rotating shafts 502 are rotatably connected to both sides of the inner side wall of the mounting base 501. Grinding rollers 503 are fixed to the outer circumference of both rotating shafts 502. A protective cover 504 is fixed to the side wall of the mounting base 501. A first motor 505 is fixed to the side wall of the protective cover 504. A worm gear 506 is fixed to the output end of the first motor 505. Worm wheels 507, sleeved on one end of the outer circumference of the rotating shaft 502, are meshed at both ends of the outer circumference of the worm gear 506. A second motor 508 is fixed to the side wall of the fixed frame 1. The second motor 508 outputs... The device has a gear 509 at one end, which meshes with a toothed ring 510 fitted on the other end of the outer circumference of the rotating drum 2. An adjustment component 6 is fixed inside the mounting frame 4. The first motor 505 and the second motor 508 are electrically connected to an external power source. The steel wire to be ground is placed between adjacent grinding rollers 503. By turning on the first motor 505, the worm gear 506 is rotated, which causes the two worm wheels 507 to rotate simultaneously, driving the two rotating shafts 502 to rotate simultaneously. This causes the grinding rollers 503 to rotate and grind the oxide layer on the surface of the steel wire. By turning on the second motor 508, the gear 509 is rotated, which causes the toothed ring 510 to rotate, driving the rotating drum 2 to rotate. This causes the connecting plate 3 to drive the mounting frame 4 to rotate, making it easier for multiple grinding rollers 503 to rotate around the center of the steel wire at the same time, which facilitates more thorough grinding of the steel wire surface and effectively improves the pretreatment efficiency.

[0036] It is worth noting that, in order to accommodate steel wires of different sizes, the adjusting assembly 6 specifically includes two lead screws 601. A handle 602 is fixedly mounted on the top of one lead screw 601. Slider blocks 603 are threaded to both ends of the outer circumference of both lead screws 601. The sidewalls of the sliders 603 are fixedly connected to the sidewalls of the mounting base 501. First bevel gears 604 are fixedly mounted on the bottom of the outer circumference of both lead screws 601. Both first bevel gears 604 mesh with second bevel gears 605. The outer circumferences of the two second bevel gears 605 are rotatably connected to the inner cavity sidewalls of the mounting bracket 4. The rotating rod 606 drives the lead screw 601 to rotate by turning the handle 602, which in turn drives the first bevel gear 604 to rotate the second bevel gear 605. This, in turn, drives the rotating rod 606 to rotate the other second bevel gear 605. This allows the two lead screws 601 to rotate simultaneously, making it easier to control and preventing jamming caused by the two lead screws 601 being out of sync. The rotation of the lead screw 601 causes the two sliders 603 to move inward simultaneously, which in turn moves the two mounting seats 501 inward. This allows the grinding roller 503 to fit into contact with the steel wire to be ground, making it easy to adapt to steel wires of different sizes and improving the grinding effect.

[0037] Next, in order to prevent the rotation of the mounting bracket 4 from being obstructed, specifically, the top middle of the side walls of the mounting base 501 is concave, and the length of the second motor 508 is less than the length of the connecting plate 3. The concave top middle of the side walls of the mounting base 501 avoids obstructing the placement of the steel wire, and the second motor 508, which is shorter than the length of the connecting plate 3, avoids obstructing the rotation of the mounting bracket 4.

[0038] Meanwhile, to facilitate the grinding of steel wire, specifically, the worm 506 is rotatably connected to the inner wall of the protective cover 504, and the heights of two adjacent grinding rollers 503 are matched. The two adjacent grinding rollers 503 with matched heights are easy to adapt to the steel wire to be processed and pre-treated, and fit more tightly for easier grinding.

[0039] Furthermore, to facilitate use by staff, specifically, multiple striped protrusions are fixedly provided on the outer circumference of the rotary handle 602, and the threads at both ends of the outer circumference of the lead screw 601 are in opposite directions. The striped protrusions facilitate increasing friction to make it easier for staff to turn the rotary handle 602. The threads at both ends of the lead screw 601 are set in opposite directions to facilitate controlling the two sliders 603 to move inward or outward simultaneously when the lead screw 601 rotates.

[0040] It is worth noting that, in order to facilitate limiting the movement of the slider 603, grooves are provided on both sides of the inner cavity of the mounting bracket 4. The size and position of the slider 603 match the size and position of the grooves. The grooves that match the size and position of the slider 603 facilitate limiting the movement of the slider 603 and prevent the slider 603 from rotating with the lead screw 601.

[0041] Finally, to improve stability, specifically, a base 7 is fixed to the bottom of the fixing frame 1. The cross-sectional dimension of the base 7 is larger than that of the fixing frame 1. The base 7, which is larger than the cross-sectional dimension of the fixing frame 1, makes it easier to install the fixing frame 1 more stably.

[0042] In addition, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.

[0043] The device or equipment models mentioned in this article may be as follows:

[0044] First motor 505: Y90S-2;

[0045] Second motor 508: Z90S-2;

[0046] Combination Figures 1-5 The specific usage process of the steel wire processing pretreatment device of this embodiment is as follows:

[0047] 1: When this device is needed for wire pretreatment, place the wire to be ground between adjacent grinding rollers 503, start the first motor 505 to make the worm 506 rotate and drive the two worm wheels 507 to rotate simultaneously, thereby causing the two rotating shafts 502 to rotate simultaneously and drive the grinding rollers 503 to rotate to grind the wire. Start the second motor 508 to make the gear 509 rotate and drive the gear ring 510 to rotate, thereby causing the rotating drum 2 to rotate and drive the mounting bracket 4 at the other end of the connecting plate 3 to rotate, and then make the grinding rollers 503 rotate around the center of the wire to fully grind the surface of the wire.

[0048] 2: Turning the lever 602 causes the lead screw 601 to rotate, which in turn drives the first bevel gear 604 to rotate. This causes the second bevel gear 605 to drive the rotating rod 606 to rotate, which in turn drives the other second bevel gear 605 to rotate, causing both lead screws 601 to rotate simultaneously. The rotation of the lead screws 601 causes the two sliders 603 to move inward simultaneously, which in turn drives the two mounting seats 501 to move inward, so that the grinding roller 503 is in contact with the steel wire to be ground.

[0049] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
