Description

Technical Field

[0001] The invention relates to the technical field of steel wire straightening, and in particular to a steel wire straightening device. Background Art

[0002] Steel wire plays an indispensable role in modern industry and daily life due to its wide application and importance. With the advancement of technology, the requirements for the quality of steel wire processing are becoming increasingly stringent. During the drawing process of steel wire, due to the influence of various factors such as lubrication effect, wire diameter, three-point straight line, etc., the linearity of the drawn steel wire will change, which often cannot meet the high standards of subsequent applications. Therefore, before the steel wire is put into use, it must be straightened to ensure its straightness and torsion.

[0003] There are many types of wire straightening devices on the market, and they use different structural designs to achieve the straightening function. For large-diameter thick steel wires, multiple sets of straightening wheels are traditionally used to straighten through slow extrusion, but this method is slow and inefficient. For small-diameter thin steel wires, multiple sets of clamps are usually used to clamp the wires in the straightening direction, and the high speed of the main shaft and clamps is used to achieve rapid rotation straightening. Although this method improves efficiency, there are wear problems, especially for steel wires with coated surfaces. This method is not suitable.

[0004] In order to meet the needs of straightening steel wires of different diameters and processing methods, it is particularly urgent to design a new type of steel wire straightening device. This device needs to be able to straighten the steel wire quickly and efficiently, and at the same time be applicable to a wider range of steel wire diameters. During use, it should also minimize the damage to the steel wire caused by friction to protect the steel wire surface, extend its service life, and improve processing quality.

[0008] In a possible implementation, a large bearing is installed in the inner hole of the turntable to ensure stable rotation of the turntable along the center.

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Figure 1 A schematic structural diagram of a steel wire straightening device provided by an exemplary embodiment of the present invention is shown. Figure 2 A schematic diagram of the structure behind the hidden baffle of a wire straightening device provided by an exemplary embodiment of the present invention is shown. Figure 3A schematic diagram of the internal structure of a steel wire straightening device provided by an exemplary embodiment of the present invention is shown, the steel wire straightening device comprises a base 3 and a shell 1 mounted on the base 3, the steel wire straightening device further comprises: a straightening mechanism 5, a baffle 17, and a gear rack mechanism 2, the straightening mechanism 5 is arranged in the shell 1, and is used to straighten the steel wire 15 to be straightened; the two baffles 17 are symmetrically distributed on both sides of the shell 1, and the straightening mechanism 5 can be movably hung between the two baffles 17; the gear rack mechanism 2 is transmission-connected with the straightening mechanism 5, and is used to drive the straightening mechanism 5 to rotate; wherein, the inlet end 18 of the steel wire 15 to be straightened is introduced into the straightening mechanism 5 from the side of one of the baffles 17, and the outlet end 19 of the steel wire 15 to be straightened is led out from the side of the other baffle 17, so as to form the straightening wire 16.

[0028] In the embodiment of the present application, the shell 1 is connected to the baffles 17 on both sides by bolts to form a closed shell to accommodate and protect the internal straightening mechanism 5.

[0029] Figure 3 FIG. 1 is a schematic diagram showing the internal structure of a steel wire straightening device provided by an exemplary embodiment of the present invention. Figure 4 The figure shows a front view of the internal structure of a steel wire straightening device provided by an exemplary embodiment of the present invention. Figure 5 An exploded schematic diagram of the internal structure of a wire straightening device provided by an exemplary embodiment of the present invention is shown, and the straightening mechanism 5 includes: a turntable 7 and a moving block 9, wherein the two turntables 7 are symmetrically distributed on the inner side of the shell 1 near the two baffles 17; a plurality of moving blocks 9 are distributed circumferentially along the central axis of the turntable 7; wherein each moving block 9 has a first pin shaft hole 22 at both ends of a side away from the wire 15 to be straightened, the first end of the first pin shaft 10 is inserted into the first pin shaft hole 22, and the second end of the first pin shaft 10 is rotatably connected to the second pin shaft hole 23 on the baffle 17 through a bearing 8; the moving block 9 has a third pin shaft hole 24 at both ends of a side close to the wire 15 to be straightened, the first end of the second pin shaft 21 is inserted into the third pin shaft hole 24, and the second end of the second pin shaft 21 is movably inserted into the limit long waist hole 25 on the turntable 7.

[0030] In the embodiment of the present application, the movement amplitude of the motion block 9 is adjustable, and the length of the limit long waist hole 25 determines the movement range of the motion block 9, thereby determining the opening diameter between multiple motion blocks 9, which can straighten steel wires of different diameters and has a wide range of applications. Multiple motion blocks 9 can move inward synchronously to shrink (reverse movement to expand the opening), apply uniform circumferential force to the steel wire, and straighten it through one-time loading, reduce the fatigue of the steel wire, shorten the straightening time, and improve work efficiency.

[0031] In the embodiment of the present application, the structural setting of the straightening mechanism 5 allows multiple motion blocks 9 to move along a predetermined path as the turntable 7 rotates, thereby applying precisely controlled pressure and guiding force to the steel wire 15 to be straightened, ensuring that the steel wire can be effectively straightened when passing through the straightening mechanism, while reducing bending and twisting, and ultimately achieving a high-quality straightening effect. This design not only improves the straightening accuracy, but also enhances the stability and durability of the system. In one example, the number of motion blocks 9 is nine.

[0032] It is worth mentioning that a large bearing 20 is also installed in the inner hole of the turntable 7 to ensure stable rotation of the turntable 7 along the center.

[0033] For further information, see Figures 1 to 5 The rack and pinion mechanism 2 includes: a large gear 14 fixedly connected to one of the turntables 7, a rack 13 meshing with the large gear 14, a small gear 12 meshing with an end of the rack 13 away from the large gear 14, and a driving motor 11 drivingly connected to the small gear 12.

[0034] In the embodiment of the present application, the design of the gear rack mechanism 2 is intended to achieve stable and controllable rotation of the turntable 7 through precise mechanical transmission. When the drive motor 11 is started, it drives the rack 13 to move linearly through the pinion 12, thereby rotating the large gear 14 meshing with the rack 13, and finally realizing the rotation of the turntable 7. It can be understood that, please refer to Figure 6 The rack and pinion mechanism 2 is fixed by an auxiliary bracket 27, and the driving motor 11 is mounted on the auxiliary bracket 27. The auxiliary bracket 27 has a guide groove 28 for the rack 13 to slide.

[0035] It should be noted that, as can be seen in the figure, the baffle 17, the rotating disk 7, and the large gear 14 all have a central hole for the steel wire to pass through. Among them, the central hole of the baffle 17 is larger than the outer diameter of the large gear 14, and does not affect the movement of the large gear 14.

[0036] Figure 7 A schematic diagram showing the structure of lubrication-related components of a wire straightening device provided by an exemplary embodiment of the present invention is shown. Figure 8 A schematic cross-sectional view of the shell of a wire straightening device provided by an exemplary embodiment of the present invention is shown, and the wire straightening device also includes: a hydraulic pump 4 whose two ends are connected to the top and bottom of the shell 1 through oil pipes respectively, a plurality of oil holes 26 are evenly distributed on the inner top of the shell 1 along the axial direction of the steel wire 15 to be straightened, and a filter plate 6 for filtering lubricating oil is provided on the inner bottom of the shell 1.

[0037] In the embodiment of the present application, the design of the lubrication-related components is intended to ensure that the components around the steel wire 15 to be straightened are fully lubricated and cooled during the straightening process, while keeping the lubricating oil clean. The hydraulic pump 4 is connected to the top and bottom of the housing 1 through an oil pipe, and can circulate the lubricating oil to a number of oil holes 26 evenly distributed on the top of the inner side of the housing, so that the lubricating oil is evenly sprayed on the steel wire and its related working parts, reducing friction, lowering temperature and improving work efficiency. At the same time, the filter plate 6 arranged at the bottom of the inner side of the housing 1 is responsible for filtering the refluxed lubricating oil, removing impurities to maintain its cleanliness, ensuring the long-term stable operation of the system and extending the service life of the mechanical parts. This setting is crucial to ensuring the accuracy and stability of the straightening process.

[0038] Next, the working principle of a steel wire straightening device involved in an embodiment of the present invention is described.

[0039] Before straightening, first drive the hydraulic pump 4 to lubricate the entire device for a certain period of time, then start the drive motor 11 to drive the entire rack and pinion mechanism 2 to move, so that the inner central opening diameter of the straightening mechanism 5 becomes larger to accommodate the steel wire 15 to be straightened, and then turn off the drive motor 11; Put the steel wire 15 to be straightened into the straightening mechanism 5, start the driving motor 11 again to run in the reverse direction, so that the inner central opening diameter of the straightening mechanism 5 becomes smaller, and the multiple motion blocks 9 shrink inward synchronously to provide uniform circumferential force to avoid twisting of the steel wire during straightening; After the inner central opening diameter of the straightening mechanism 5 reaches the diameter of the steel wire, the plurality of moving blocks 9 remain in this state for a period of time to avoid rebound of the steel wire after straightening, thereby completing the straightening of the steel wire.

[0040] In summary, a shell is installed on a base, a straightening mechanism for straightening the steel wire to be straightened is arranged in the shell, two baffles are symmetrically distributed on both sides of the shell, and the straightening mechanism can be movably hung between the two baffles; a gear rack mechanism is transmission-connected with the straightening mechanism to drive the straightening mechanism to rotate; wherein, the inlet end of the steel wire to be straightened is introduced into the straightening mechanism from one of the baffle sides, and the outlet end of the steel wire to be straightened is led out from the other baffle side to form a straightened steel wire. In this case, the straightening requirements of steel wires of different diameters and processing methods can be met, the steel wire can be straightened quickly and efficiently, and the damage to the steel wire caused by friction can be minimized to protect the surface of the steel wire and improve the straightening quality.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments disclosed in the present invention can be understood according to specific circumstances.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
