Through the description of the specific embodiments, a more in-depth and specific understanding can be gained of the technical means and effects adopted by this utility model to achieve the intended purpose. However, the accompanying drawings are only provided for reference and illustration and are not intended to limit the technical solution of this utility model.

[0024] Example 1

[0025] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a cold straightening device for a bright surface of an alloy wire rod provided in an embodiment of this utility model.

[0026] The utility model provides a kind of alloy wire rod bright surface cold straightening device, comprising: the discharge rack 100, straightening module 200, track straightening power module 300 and online cutting module 400 are sequentially arranged;Wherein, the discharge rack 100 is provided with pay-off wheel, for alloy wire rod coil pay-off;Straightening module 200 is provided with several groups of straightening press wheel, for alloy wire rod is straightened for the first time by several groups of straightening press wheel;Track straightening power module 300 is provided with at least two groups of track drive unit 310, and the spacing adjustable compression groove is arranged between two groups of track drive unit 310, and alloy wire rod is straightened for the second time by compression groove after first straightening;Online cutting module 400 is used to cut alloy wire rod after second straightening.

[0027] Illustratively, the discharge rack 100 is a non-free type pay-off rack, and the base position thereof is provided with a magnetic powder brake 110. The pay-off speed of the alloy wire rod is controlled by the magnetic powder brake 110, and a braking force is provided.

[0028] Specifically, the magnetic powder brake 110 uses magnetic powder as a medium. In the case of power supply, a magnetic powder chain is formed to transmit torque. In the braking process, the magnetic field generated by the coil fills the internal gap with high-permeability powder, so that an opposite force opposite to the movement direction of the alloy wire rod is generated in the pay-off process, thereby rapidly stopping the pay-off wheel to achieve braking. The magnetic powder brake 110 can prevent the generation of curves, broken lines or irregular knots in the process of excessive free pay-off, thereby avoiding production accidents caused by poor discharge.

[0029] It can be understood that the magnetic powder brake 110 is widely used in the tension control and braking of pay-off and winding in the processing industry. Therefore, the related structure and principle thereof can be referred to the related prior art, and the specific structure thereof is not limited in the embodiment.

[0030] As shown in Figure 2 and Figure 3 , the structure of the first straightening unit provided by the utility model embodiment is shown in Figure 2 , and the structure of the straightening press wheel provided by the utility model embodiment is shown in Figure 3 .

[0031] In an optional embodiment, the straightening module 200 comprises a first straightening unit 210. The first straightening unit 210 comprises several groups of straightening press wheels, and the several groups of straightening press wheels are distributed in two rows, and the straightening press wheels in the two rows are arranged in staggered positions.

[0032] In an optional embodiment, the straightening module 200 further comprises a second straightening unit 220. The second straightening unit 220 comprises several groups of straightening press wheels, and the several groups of straightening press wheels are distributed in two rows, and the straightening press wheels in the two rows are arranged in staggered positions.

[0033] For example, the straightening pressure rollers in the first straightening unit 210 are divided into two columns, the upper column is provided with four straightening pressure rollers, and the lower column is provided with four straightening pressure rollers in staggered arrangement; the straightening pressure rollers in the second straightening unit 220 are divided into two rows, the left row is provided with four straightening pressure rollers, and the right row is provided with four straightening pressure rollers in staggered arrangement.

[0034] Further, the first straightening unit 210 and the second straightening unit 220 are arranged perpendicularly to each other.

[0035] Specifically, the axis directions of the straightening pressure rollers in the first straightening unit 210 are all arranged along the horizontal direction, that is, the straightening pressure rollers in the first straightening unit 210 apply longitudinal pressure to the alloy wire rod; the axis directions of the straightening pressure rollers in the second straightening unit 220 are all arranged along the vertical direction, that is, the straightening pressure rollers in the second straightening unit 220 apply transverse pressure to the alloy wire rod.

[0036] In an optional embodiment, each straightening pressure roller in the first straightening unit 210 and the second straightening unit 220 is connected with a screw rod adjusting unit; the screw rod adjusting unit is used to adjust the position of each straightening pressure roller individually.

[0037] It should be noted that the first straightening unit 210 and the second straightening unit 220 can be arranged in the same structure, but the number of straightening pressure rollers in the first straightening unit 210 and the second straightening unit 220 can be different, and only the first straightening unit 210 is taken as an example below.

[0038] For example, the axis directions of the straightening pressure rollers 211 in the first straightening unit 210 are all arranged along the horizontal direction as two columns, and four straightening pressure rollers 211 are arranged in each column; each straightening pressure roller 211 is arranged in a chute, and each straightening pressure roller 211 is connected with a screw rod adjusting unit 212, which can move the position of each straightening pressure roller 211 along the direction of the chute, so as to make the straightening pressure roller 211 close to or away from the alloy wire rod, thereby changing the bending force applied to the alloy wire rod. For example, when the straightening pressure roller 211 is close to the alloy wire rod, the corresponding bending force applied to the alloy wire rod increases, thereby achieving control over the straightening process.

[0039] It should be noted that the surface of the straightening pressure roller 211 is smooth, the alloy wire rod is straightened by bending deformation, and the surface quality of the alloy wire rod will not be affected during the bending process, which is conducive to realizing the bright surface cold straightening of the alloy wire rod.

[0040] Further, the first straightening unit 210 and the second straightening unit 220 can be further connected with a digital display unit, through which the position of each straightening pressure roller 211 can be displayed, for example, the greater the distance of the downward adjustment of the straightening pressure roller 211 displayed on the digital display unit, the greater the bending force applied to the alloy wire rod, so that the straightening process can be accurately controlled.

[0041] The working principle of the straightening module 200 will be described below by taking the first straightening unit 210 horizontally arranged and the second straightening unit 220 vertically arranged as an example: the first straightening unit 210 and the second straightening unit 220 are both provided with a plurality of groups of straightening pressure rollers arranged in a staggered manner, and the position of each straightening pressure roller can be finely adjusted according to the hardness and diameter of the alloy wire rod. The alloy wire rod produces repeated snake-shaped deformation in the first straightening unit 210, changes to the vertical direction in the second straightening unit 220, and again produces repeated snake-shaped deformation, thereby eliminating the original bending stress of the alloy wire rod and strengthening the straightness of the alloy wire rod. Moreover, since the straightening pressure rollers are in contact with the alloy wire rod through smooth surfaces, the alloy wire rod surface is not damaged, has no scratches, and has no oval deformation, and the consistency of the straightened product is better.

[0042] As shown in Figure 4 , the structure schematic diagram of the track straightening power module is provided. Figure 4

[0043] Similarly, since the structures of the two groups of track driving units 310 are the same, only one of the two groups of track driving units 310 will be taken as an example for description below.

[0044] In the embodiment, the structures of the two groups of track driving units 310 are the same, and each includes a track 311, a driving pulley 312, and a compression roller 313; wherein the two driving pulleys 312 are symmetrically arranged on the two sides of the length direction of the track 311; and a plurality of compression rollers 313 are arranged between the two driving pulleys 312; the compression roller 313 is used for compressing the track 311.

[0045] In an optional embodiment, the tracks 311 of the two groups of track driving units 310 are arranged side by side and compressed against each other, and a compression groove is formed between the two tracks 311, and the width of the compression groove matches the diameter of the alloy wire rod.

[0046] For example, the distance between the two tracks 311 can be adjusted individually; and since the length of the straight wire and the requirements of the pay-off speed and the total length are different, the length of the track 311 can also be adaptively set. In addition, the track 311 with a compression groove of different width can also be replaced, or the width of the compression groove can be changed by secondary processing. ​

[0047] Exemplarily, the driving pulley 312 can be a gear, and the inner side of the corresponding track 311 is also provided with a rack layer engaged with the gear, and the driving force is provided through the engagement of the gear and the rack.

[0048] Further, the driving pulley 312 is connected with a driving mechanism (not shown in the figure), which can include a servo motor and a speed reducer, and the servo motor is used to drive the track rotation of the two groups of track driving units 310, and drive the pay-off rack 100 to pay off wire through the tracks 311 of the two groups of track driving units 310.

[0049] In addition, a blocking layer can also be provided on both sides of the rack layer, such as a blocking layer made of rubber material covering part of the inner side surface of the track 311, and the rack layer is set to be equal to the height of the blocking layer, so that the inner side of the track 311 maintains the same height, and also prevents the interference between the compression roller 313 and the rack layer.

[0050] Exemplarily, the compression roller 313 can be connected to a driving compression mechanism, and the driving compression mechanism is used to adjust the compression force of the compression roller 313 on the track 311, such as a cylinder or a screw adjusting mechanism. In addition, a plurality of compression rollers 313 can be set as a group, and a plurality of compression rollers 313 in a group are adjusted by one driving compression mechanism, and the remaining groups are also respectively connected with driving compression mechanisms.

[0051] The working principle of the track straightening power module 300 of the embodiment is that the track straightening power module 300 is driven by a servo motor as the power source of the entire device, the tracks 311 of the two groups of track driving units 310 are arranged side by side and are tightly compacted with each other, the middle part of the track 311 is provided with a compression groove, and the width of the compression groove is adjustable. The alloy wire rod is straightened twice in the compression length range of the track 311, and the compression groove formed between the two groups of tracks 311 also prevents the alloy wire rod from deviating, and improves the stability of the alloy wire rod straightening.

[0052] In an optional embodiment, a plurality of guide wheels can also be provided on the wire paying-off path to maintain the tension on the alloy wire rod and prevent the alloy wire rod from deviating. At the same time, in order to avoid affecting the surface quality of the alloy wire rod, a flexible buffer material can be provided on the surface of the guide wheel.

[0053] In an optional embodiment, the online cutting module 400 can be provided with a length sensor for measuring the length of the passing alloy wire rod in real time; at the same time, the online cutting module 400 is electrically connected to an external controller, and the external controller collects the measurement data of the length sensor in real time and controls the online cutting module 400 to cut according to the measurement data. Specifically, the preset length of the alloy wire rod is set through the external controller, and when the passing alloy wire rod reaches the preset length, the cutting knife of the online cutting module 400 is controlled by the external controller to automatically cut the alloy wire rod to obtain the alloy wire rod meeting the length requirement. In addition, the unwinding speed of the alloy wire rod can also be controlled, and the length control of the alloy wire rod can also be realized through timing cutting after the unwinding speed is determined.

[0054] It can be understood that the specific structure of the online cutting module 400 can be realized by referring to the related prior art, and therefore will not be described in detail.

[0055] In an optional embodiment, a straight wire collecting platform 500 is further arranged behind the online cutting module 400 for collecting the alloy wire rod after cutting. The height of the straight wire collecting platform 500 is set to be the height of the cutting outlet of the online cutting module 400, so that high-speed and accurate online cutting can be realized under the condition of uninterrupted production, and the straight wire rod meeting the length requirement can be collected.

[0056] The working principle of the alloy wire rod bright surface cold straightening device of the embodiment is that the coil (bright surface non-oxidation) of the alloy wire rod to be straightened is placed on the unwinding wheel of the material unwinding frame 100, one end of the alloy wire rod is sequentially threaded through the straightening module 200, the track straightening power module 300 and the online cutting module 400, repeated serpentine deformation is generated in the plurality of straightening pressure wheels in the first straightening unit 210, the direction is changed to vertical in the second straightening unit 220, and repeated serpentine deformation is generated again in the plurality of straightening pressure wheels in the second straightening unit 220, to complete the first straightening process.

[0057] Since the material unwinding frame 100 is passive unwinding, the track straightening power module 300 also functions to drive the unwinding for providing running power to the entire device; the tracks of the two groups of track driving units 310 are arranged side by side and tightly compacted with each other, and only the middle part is relatively provided with a compacting groove, the diameter of the compacting groove matches the diameter of the alloy wire rod, and at the same time, the compacting groove also functions to prevent the alloy wire rod from deviating, thereby improving the stability of the straightening of the alloy wire rod. The alloy wire rod after the first straightening is straightened for the second time in the compacting groove, and then is subjected to online cutting without stopping in the online cutting module 400 to obtain the straight wire rod meeting the length requirement, and finally is collected on the straight wire collecting platform 500 to complete the cold straightening of the alloy wire rod bright surface.
