Description

Technical Field

[0001] This application belongs to the field of cold-rolled coil transfer technology, specifically relating to a tooling for assisting in the shipment of cold-rolled coils. Background Technology

[0002] Silicon steel, also known as electrical steel, contains 1.0-4.5% silicon and less than 0.08% carbon. With the continuous development of the electrical steel market in China, the production of silicon steel has increased rather than decreased. The thickness of finished silicon steel sheets is typically between 0.23mm and 0.35mm, with products trending towards extremely thin specifications. The production of silicon steel involves various processes, from hot rolling to normalizing, and then rolling into thin strip steel, i.e., cold-rolled silicon steel coils. These coils are generally not packaged and are transported directly from the cold rolling workshop to the annealing process for the next step.

[0003] Winters in the north are windy and the wind is strong. When the factory buildings form a narrow tube effect, the wind force will be amplified. This will cause great trouble for the transportation of cold-rolled silicon steel coils. Strong winds can easily lift or even overturn the tail of the cold-rolled coils, tearing the silicon steel. It also poses a huge safety hazard to the operators during transportation. Summary of the Invention

[0004] To address the technical problem that the strip of cold-rolled coils is often overturned and torn by strong winds during transport from the cold rolling workshop to the unloading workshop, posing a safety hazard to operators, this application provides a tooling for assisting in the shipment of cold-rolled coils.

[0005] This application provides a tooling for assisting in the shipping of cold-curled cigarettes, comprising: Telescopic mechanism; The magnetic assemblies are provided in multiples, and the multiple magnetic assemblies are distributed at intervals along the axial direction of the cold-hardened roll. The multiple magnetic assemblies are all installed on the telescopic mechanism. The magnetic assemblies include magnetic elements for magnetically attracting the tail of the cold-hardened roll. A slide rail extends along the axial direction of the cold-hardened roll, and the telescopic mechanism slides in cooperation with the slide rail; Two drive handles are provided, which are sequentially distributed along the axial direction of the cold-hardened roll. The drive handles are used to drive the telescopic mechanism to extend or retract along the axial direction of the cold-hardened roll, thereby adjusting the spacing between at least two magnetic assemblies.

[0006] In some embodiments, the telescopic mechanism is a four-bar telescopic frame, and the slide rail extends along the axial direction of the cold-hardened roll; The hinge shafts at the two opposite corners of the parallelogram in the four-bar telescopic frame are slidably engaged with the slide rail, and the upper ends are connected to the two drive handles one by one.

[0007] In some embodiments, the slide rail has a receiving cavity and an upper opening and a lower opening communicating with the receiving cavity. The receiving cavity, the upper opening and the lower opening all extend along the axial direction of the cold-hardened roll. The upper end of the hinge shaft passes through the lower opening, the receiving cavity and the upper opening and extends out of the slide rail.

[0008] In some embodiments, the diameter of the shaft segment of the hinge shaft located within the receiving cavity is greater than the width of the lower opening.

[0009] In some embodiments, the hinge shaft is connected to a slider, the slider gap being located within the receiving cavity along an axial direction perpendicular to the cold-hardened roll, and the size of the slider being larger than the size of the lower opening.

[0010] In some embodiments, the hinge shaft is rotatably connected to two corresponding links in the four-bar telescopic frame, and the hinge shaft is fixedly connected to the slider.

[0011] In some embodiments, the hinge shaft is rotatably connected to one of the two corresponding links in the four-bar telescopic frame and fixedly connected to the other link, and the hinge shaft is rotatably connected to the slider.

[0012] In some embodiments, the magnetic traction assembly includes two magnetic traction elements arranged at an axial distance perpendicular to the cold-rolled coil.

[0013] In some embodiments, the magnetic traction assembly is provided in three parts, namely a first magnetic traction assembly, a second magnetic traction assembly, and a third magnetic traction assembly arranged sequentially along the axial direction of the cold-hardened roll; the two drive handles are located on both sides of the second magnetic traction assembly along the axial direction of the cold-hardened roll.

[0014] In some embodiments, the drive handle includes a connecting rod and an inverted U-shaped handle, the inverted U-shaped handle being connected to the connecting rod; The upper end of the hinge shaft is connected to the corresponding connecting rod, and the connecting rod is perpendicular to the slide rail.

[0015] The tooling provided according to the embodiments of this application includes a telescopic mechanism, magnetic assemblies, a slide rail, and a drive handle. Multiple magnetic assemblies are provided, spaced apart along the axial direction of the cold-rolled coil. Each magnetic assembly is mounted on the telescopic mechanism and includes a magnetic element for magnetically attracting the tail of the cold-rolled coil. The slide rail extends along the axial direction of the cold-rolled coil, and the telescopic mechanism slides in cooperation with the slide rail. Two drive handles are provided, sequentially distributed along the axial direction of the cold-rolled coil. The drive handles are used to drive the telescopic mechanism, causing it to extend and retract along the axial direction of the cold-rolled coil, thereby adjusting the spacing between at least two magnetic assemblies.

[0016] The telescopic mechanism can extend and retract along the axial direction of the cold-rolled coil under the action of the drive handle. This allows for adjustable spacing between at least two magnetic assemblies installed on the telescopic mechanism, accommodating cold-rolled coils of different widths. After the cold-rolled coil comes off the production line, the operator operates the handle to attach the magnetic assemblies of the fixture to the tail of the strip. Due to magnetic force, the tail of the strip is magnetically attracted to the inner ring of the strip, achieving temporary fixation. It can then be transported to the unloading workshop by a transfer trolley. Even in strong winds, it remains intact, protecting the operators. Because the fixture has multiple magnetic assemblies, it can magnetically attract the tail of the strip at multiple points. Furthermore, the magnetic area of ​​each magnetic assembly can be set smaller, satisfying both the function of magnetically fixing the tail of the strip and facilitating its removal.

Detailed Implementation

[0023] To enable those skilled in the art to better understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0024] According to the first aspect of this application, a tooling for assisting in the shipment of cold-rolled coils is provided. This tooling can fix the tail of cold-rolled coils of different widths, ensuring that they are not blown over or torn by the wind during transfer from the cold rolling workshop to the unloading rack, thus protecting the safety of the operators.

[0025] This application is described below with reference to the accompanying drawings and specific embodiments: Please see Figures 1 to 4 The tooling for assisting in the shipment of cold-rolled rigid rolls provided in this application embodiment includes a telescopic mechanism 10, magnetic assemblies 20, a slide rail 30, and a drive handle 40. Multiple magnetic assemblies 20 are provided, spaced apart along the axial direction of the cold-rolled rigid roll 50. Each magnetic assembly 20 is mounted on the telescopic mechanism 10 and includes a magnetic element 21 for magnetically attracting the tail 51 of the cold-rolled rigid roll 50. The slide rail 30 extends along the axial direction of the cold-rolled rigid roll 50, and the telescopic mechanism 10 slides in cooperation with the slide rail 30. Two drive handles 40 are provided, sequentially distributed along the axial direction of the cold-rolled rigid roll 50. The drive handles 40 are used to drive the telescopic mechanism 10, causing it to extend and retract along the axial direction of the cold-rolled rigid roll 50, thereby adjusting the spacing between at least two magnetic assemblies 20.

[0026] The telescopic mechanism 10 can extend and retract along the axial direction of the cold-hardened roll 50 under the action of the drive handle 40, so that the spacing between at least two magnetic assemblies 20 installed on the telescopic mechanism 10 is adjustable, thereby accommodating cold-hardened rolls 50 of different widths.

[0027] After the cold-rolled coil 50 comes off the production line, the operator should refer to the operating handle. Figure 5 The magnetic component 20 of the tooling is attracted to the tail 51 of the strip. Due to the magnetic force, the tail 51 will be magnetically attracted to the inner ring of the strip, thus temporarily fixing the tail 51. It can be transported to the unloading workshop by the transfer trolley. It can remain intact even in strong winds, thus protecting the workers.

[0028] Since the tooling is equipped with multiple magnetic components 20, it can magnetically attract the tail 51 at multiple points, and the magnetic area of ​​each magnetic component 21 can be set to be smaller, which can not only satisfy the function of magnetically fixing the tail 51, but also make it easy to pick up.

[0029] In some embodiments, the telescopic mechanism 10 is a four-bar telescopic frame 10a, with the slide rail 30 extending axially along the cold-hardened roll 50; the middle of the hinge shafts at the two opposite corners of the parallelogram in the four-bar telescopic frame 10a are slidably engaged with the slide rail 30, and the upper end is connected to two drive handles 40 one by one.

[0030] The four-bar telescopic frame 10a may include four links. For clarity, please refer to [link to documentation]. Figure 3The four links are named first link 11, second link 12, third link 13, and fourth link 14. The middle parts of the first link 11 and the second link 12 are hinged by the first hinge shaft 15, and the middle parts of the third link 13 and the fourth link 14 are hinged by the second hinge shaft 16. The end of the first link 11 is hinged to the end of the third link 13, and the end of the second link 12 is hinged to the end of the fourth link 14. Thus, the four-bar telescopic frame 10a forms a parallelogram-shaped structure. The middle part of the first hinge shaft 15 engages with the slide rail 30, and the middle part of the second hinge shaft 16 engages with the slide rail 30. The upper ends of the first hinge shaft 15 and the second hinge shaft 16 are respectively connected to the two drive handles 40. In this way, by moving the two drive handles 40 closer or further apart, the four-bar telescopic component can be shortened or shortened, allowing any two adjacent magnetic components 20 to move closer or further apart to accommodate cold-rolled coils 50 of different widths.

[0031] In other embodiments, the telescopic mechanism 10 may further include a first telescopic tube and a second telescopic tube. The first telescopic tube is fitted over the second telescopic tube with a gap. The second telescopic tube is at least partially exposed outside the first telescopic tube. A portion of the magnetic attraction component 20 is installed on the first telescopic tube, and the remaining magnetic attraction components 20 are installed on the portion of the second telescopic tube exposed outside the first telescopic tube. The first telescopic tube is slidably engaged with the slide rail 30 via a first bracket, and the second telescopic tube is slidably engaged with the slide rail 30 via a second bracket. Two drive handles 40 are respectively connected to the first bracket and the second bracket, which can also realize the spacing adjustment of at least two magnetic attraction components 20, thereby adapting to cold-rolled rolls 50 of different widths.

[0032] In some embodiments, please refer to Figure 4 The slide rail 30 is provided with a receiving cavity 32 and an upper opening 33 and a lower opening 31 connected to the receiving cavity 32. The receiving cavity 32, the upper opening 33 and the lower opening 31 all extend along the axial direction of the cold-hardened roll 50. The middle part of the first hinge shaft 15 passes through the lower opening 31, the receiving cavity 32 and the upper opening 33, and the upper end extends out of the slide rail 30. The middle part of the second hinge shaft 16 passes through the lower opening 31, the receiving cavity 32 and the upper opening 33, and the upper end extends out of the slide rail 30.

[0033] The slide rail 30 is restricted to moving only along the axial direction of the cold-hardened roll 50 by the upper opening 33, the receiving cavity 32 and the lower opening 31, thereby improving the stability of the telescopic mechanism 10 during the telescopic process.

[0034] In other embodiments, two slide rails 30 are provided, and the two slide rails 30 are distributed at intervals along an axial direction perpendicular to the cold-hardened roll 50. The interval between the two slide rails 30 forms a space to accommodate the first hinge shaft 15 and the second hinge shaft 16. The first hinge shaft 15 and the second hinge shaft 16 are both stepped shafts. The large shaft end face of the stepped shaft slides and engages with the top surface of the two slide rails 30, which can also improve the stability of the telescopic mechanism 10 during the telescopic process.

[0035] In some embodiments, please refer to Figure 2 as well as Figure 4 The first hinge shaft 15 is connected to the first slider 17. The gap of the first slider 17 is located within the receiving cavity 32. Along the axial direction perpendicular to the cold-hardened roll 50, the size of the first slider 17 is larger than the size of the lower opening 31. Similarly, the second hinge shaft 16 is connected to the second slider 18. The gap of the second slider 18 is located within the receiving cavity 32. Along the axial direction perpendicular to the cold-hardened roll 50, the size of the second slider 18 is larger than the size of the lower opening 31. This can prevent the slide rail 30 from disengaging from the first hinge shaft 15 and from disengaging from the second hinge shaft 16, thereby improving the stability of the tooling.

[0036] In other embodiments, the diameter of the shaft segment of the first hinge shaft 15 located in the receiving cavity 32 is greater than the width of the lower opening 31, and the diameter of the shaft segment of the second hinge shaft 16 located in the receiving cavity 32 is greater than the width of the lower opening 31. This can prevent the slide rail 30 from disengaging from the first hinge shaft 15 and from disengaging from the second hinge shaft 16, thereby improving the stability of the tooling.

[0037] In some embodiments, the first hinge shaft 15 is rotatably connected to both the first connecting rod 11 and the second connecting rod 12, and the first hinge shaft 15 is fixedly connected to the first slider 17; similarly, the second hinge shaft 16 is rotatably connected to both the third connecting rod 13 and the fourth connecting rod 14, and the second hinge shaft 16 is fixedly connected to the second slider 18, thereby realizing the extension and retraction of the telescopic mechanism 10 under the guidance of the slide rail 30.

[0038] In other embodiments, the first hinge shaft 15 is rotatably connected to one of the first connecting rod 11 and the second connecting rod 12, and is fixedly connected to the other connecting rod. The first hinge shaft 15 is rotatably connected to the first slider 17. Similarly, the second hinge shaft 16 is rotatably connected to one of the third connecting rod 13 and the fourth connecting rod 14, and is fixedly connected to the other connecting rod. The second hinge shaft 16 is rotatably connected to the second slider 18, thereby realizing the extension and retraction of the telescopic mechanism 10 under the guidance of the slide rail 30.

[0039] In some embodiments, please refer to Figure 1The magnetic traction assembly 20 may include two magnetic suction elements 21, which are arranged at intervals along an axial direction perpendicular to the cold-rolled coil 50. There are three magnetic traction assemblies 20: a first magnetic traction assembly 20a, a second magnetic traction assembly 20b, and a third magnetic traction assembly 20c, arranged sequentially along the axial direction of the cold-rolled coil 50. The two magnetic suction elements 21 of the first magnetic traction assembly 20a are respectively installed on the ends of the first connecting rod 11 and the second connecting rod 12 away from the third connecting rod 13. The two magnetic suction elements 21 of the second magnetic traction assembly 20b are respectively installed on the ends of the first connecting rod 11 and the second connecting rod 12 near the third connecting rod 13. The two magnetic suction elements 21 of the third magnetic traction assembly 20c are respectively installed on the ends of the third connecting rod 13 and the fourth connecting rod 14 away from the first connecting rod 11, forming a two-row, three-column matrix for fixing the strip steel, resulting in good fixing effect. In some other embodiments, the magnetic traction assembly 20 may also have only one magnetic suction element 21, which can also achieve the fixing of the strip tail 51.

[0040] In other embodiments, the magnetic assemblies 20 may be configured as four, six, or eight, and the magnetic assemblies 21 may be installed not only at the end of the connecting rod but also in the middle of the connecting rod.

[0041] The magnetic attractor 21 can be a permanent magnet or an electromagnetic component. If the magnetic attractor 21 is an electromagnetic component, a power supply is also required.

[0042] In some embodiments, the two drive handles 40 are located on both sides of the second magnetic assembly 20b along the axial direction of the cold-hardened roll 50, which can improve the stability of the telescopic mechanism 10 during the telescopic process.

[0043] In some embodiments, please refer to Figure 4 The drive handle 40 includes a connecting rod 41 and an inverted U-shaped handle 42, which is connected to the connecting rod 41. The upper end of the first hinge shaft 15 is connected to the corresponding connecting rod 41, and the upper end of the second hinge shaft 16 is connected to the corresponding connecting rod 41. The connecting rod 41 is perpendicular to the slide rail 30, which not only realizes the connection between the drive handle 40 and the first hinge shaft 15 and the second hinge shaft 16, but also makes it easy for the operator to grip.

[0044] To address the problem of strong winds and the funnel effect causing the tail of cold-rolled silicon steel coils to be lifted during shipment, this application provides a tooling solution for assisting in the shipment of cold-rolled silicon steel coils. This tooling fits snugly against the tail of the coil, preventing it from being affected by strong winds, thus achieving safe and efficient shipment. It enables safe on-site transportation of cold-rolled silicon steel coils, eliminating the impact of weather and climate on shipment. This invention has a simple structure, is easy to manufacture, uses widely available materials, has low cost, is safe and convenient to use, and can be reused indefinitely, making it widely applicable.
