Description

A steel coil shearing device Technical Field

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

[0002] Steel plates, especially thin plates, are commonly used raw materials in people's production and daily life. They can be processed into products of various shapes through bending, stamping and other methods. They are widely used as shells, shelves and other structures.

[0003] Since thin steel sheets are usually stored in steel coils after manufacturing, and their total length and width are relatively long, the steel coils need to be cut before processing. That is, the steel coils are cut into steel products with narrower width and / or shorter length according to the required length and width. The industry usually uses steel coil cutting equipment to carry out the cutting operation. Currently, existing steel coil shearing equipment on the market, such as the thin coil steel shearing device disclosed in patent CN211248523U, has a pressure roller slidably connected to the inner wall of a support frame. A fixed frame is fixedly connected to the top of the support frame, and a hydraulic cylinder is fixedly connected inside the fixed frame. A telescopic rod is fixedly connected to the output end of the hydraulic cylinder, passing through the support frame and the pressure roller. One side of the pressure roller has a shearing assembly, which includes a rotating shaft that rotates on the inner wall of the support frame. Both ends of the rotating shaft are screwed to limit plates. Between the two limit plates are four annular blades and several sleeves. The annular blades and sleeves are engaged and fixed to the outer wall of the rotating shaft. The hydraulic cylinder is connected to an external hydraulic oil station for transmission. In addition, a take-up roller is also provided on the fixed frame. During the shearing process, the steel strip is first wound around the take-up roller. Then, according to the production requirements for the width of the steel strip, the number of sleeves between two adjacent annular blades is adjusted, thereby changing the spacing between the annular blades to adjust the width of the sheared steel strip. Finally, limit plates are provided to confine the sleeves and annular blades on the rotating shaft. Furthermore, the hydraulic cylinder operates, driving a telescopic rod fixed to its output end, which in turn causes a pressure roller fixed to it to move linearly. The pressure roller presses down on thinner steel, preventing the steel from swaying during shearing and improving the quality of the shearing. After the pressure roller presses down on the steel strip, the rotating shaft drives the annular blade to cut the steel strip. Finally, the winding roller rotates to wind up the sheared steel strip. Although the above device can cut steel plates, it can only cut in the width direction (longitudinal). Cutting in the length direction (transverse) requires another device. This results in transverse cutting occurring before or after longitudinal cutting. When transverse cutting occurs before longitudinal cutting, each transverse cut requires winding before transferring to the same device for longitudinal cutting, leading to high repetition, low efficiency, and high cost. When transverse cutting occurs after longitudinal cutting, the actual length of the longitudinally cut steel strip is greater than the required transverse cutting length, resulting in material waste and further increasing costs. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, this invention aims to provide a steel coil shearing device with a 180° adjustable flip-shear assembly mounted on the frame. The flip-shear assembly includes both a rolling shear section and a transverse shear section. The rolling shear section achieves longitudinal shearing, while the transverse shear section achieves transverse shearing. This ensures that the longitudinal and transverse shearing are located in the same vertical plane, thereby guaranteeing that the longitudinal and transverse cuts are in the same position. This avoids the problems of high repetition, low efficiency, and high cost caused by different transverse and longitudinal cut positions.

[0005] The specific technical solution is as follows:

[0006] A steel coil shearing device includes a frame and a pressure roller, the pressure roller being rotatably mounted on the frame, and further includes:

[0007] The overturning and shearing assembly includes an overturning frame, a rolling shearing section, and a transverse shearing section. Along the conveying direction of the steel coil, pressure rollers are provided at the front and rear of the overturning and shearing assembly. Both ends of the overturning frame are rotatably mounted on lifting frames, and both lifting frames are mounted on the machine frame. At the same time, the transverse shearing section is provided at the upper part of the overturning frame, the rolling shearing section is rotatably mounted at the lower part of the overturning frame, and the two sides of the middle part of the overturning frame are rotatably mounted on the corresponding lifting frames.

[0008] In the aforementioned steel coil shearing equipment, vertical frames are provided on both sides of the frame. Each vertical frame has a vertical groove, with the two sides of the groove penetrating the inner and outer walls of the vertical frame, respectively. The two vertical frames correspond one-to-one with two lifting frames, and the lifting frames are slidably installed in the corresponding grooves.

[0009] In the aforementioned steel coil shearing equipment, each upright includes an outer frame and an inner frame, and the chute includes an outer slide rail and an inner slide rail. The height of the outer frame is higher than the height of the inner frame. The outer slide rail is set on the outer frame, and the inner slide rail is set on the inner frame. The inner slide rail is connected to the outer slide rail, and the upper end of the inner slide rail penetrates the top surface of the inner frame.

[0010] In the aforementioned steel coil shearing equipment, the lifting frame is slidably disposed in the outer slide rail of the corresponding upright, and the end of the tilting frame is slidably disposed in the inner slide rail of the corresponding upright. After the lifting frame rises to a predetermined height, the tilting frame disengages from the inner slide rail.

[0011] In the aforementioned steel coil shearing equipment, the lifting frame includes a lifting slider and a lifting driver. The lifting slider is slidably disposed in an outer slide rail, and the lifting driver is mounted on the outer frame, with the drive shaft of the lifting driver being poweredly connected to the lifting slider.

[0012] In the aforementioned steel coil shearing equipment, a tilting drive is installed on the lifting slider, and an extended rotating shaft is provided at the end of the tilting frame. The rotating shaft is rotatably installed on the lifting slider and is poweredly connected to the tilting drive.

[0013] The steel coil shearing equipment described above includes a horizontal shearing section comprising a horizontal cutter and a connecting section. Both ends of the horizontal cutter are provided with connecting sections, which are respectively installed on the two ends of the upper part of the tilting frame, and the blade of the horizontal cutter is arranged facing outward from the tilting frame.

[0014] In the aforementioned steel coil shearing equipment, the connecting part includes connecting blocks and threaded fasteners. The connecting blocks are installed at both ends of the horizontal cutter, and the two connecting blocks are respectively connected to the two ends of the upper part of the flipping frame through threaded fasteners.

[0015] The steel coil shearing equipment described above includes a rolling shearing unit comprising a roller, a roller cutter, and a sleeve. The two ends of the roller are rotatably mounted on the two ends of the lower part of the tilting frame. The roller cutter and the sleeve are both sleeved outside the roller and are both circumferentially limited by the roller.

[0016] In the aforementioned steel coil shearing equipment, an adjustment structure is provided between one end of the roller and the tilting frame. The adjustment structure includes a telescopic rod and a locking pin. The telescopic rod is telescopically installed on the tilting frame and arranged radially along the roller. A locking pin is provided between the telescopic rod and the tilting frame. One end of the telescopic rod is rotatably connected to the corresponding end of the roller.

[0017] In the aforementioned steel coil shearing equipment, the pressure rollers include an upper pressure roller and a lower pressure roller, which are arranged in parallel and distributed vertically in upper and lower layers, and the steel coil passes between the upper pressure roller and the lower pressure roller.

[0018] In the aforementioned steel coil shearing equipment, telescopic actuators are installed between both ends of the upper pressure roller and the frame, and the telescopic actuators move in the vertical direction.

[0019] The positive effects of the above technical solution are:

[0020] The aforementioned steel coil shearing equipment, by setting a rotatable flip-shearing assembly on the frame, with both ends of the flip frame of the flip-shearing assembly rotatably mounted on a lifting frame, and the lifting frame slidingly mounted on the frame in the vertical direction, and simultaneously installing a rolling shearing section and a transverse shearing section on the lower and upper parts of the flip frame respectively, allows for longitudinal shearing of the steel plate using the rolling shearing section, while transverse shearing is performed by flipping the transverse shearing section to the shearing position using the flip frame. This ensures that the rolling shearing section and the transverse shearing section are located in the same vertical plane, guaranteeing that the longitudinal and transverse cuts of the steel coil are at the same position. This avoids the problems of high repetition, low efficiency, and serious waste caused by different transverse and longitudinal cut positions, thus meeting the needs of large-scale production and manufacturing.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following embodiments are described in detail with reference to Figures 1 and 2. However, the following content is not intended to limit this utility model.

[0025] Figure 1 is a structural diagram of an embodiment of the steel coil shearing device of the present invention; Figure 2 is a schematic diagram of the installation between the lifting frame, the tilting frame and the machine frame in a preferred embodiment of the present invention. As shown in Figures 1 and 2, the steel coil shearing device provided in this embodiment includes: a machine frame 1, a pressure roller 2 and a tilting shearing assembly 3. In this case, the pressure roller 2 is rotatably mounted on the machine frame 1, and the pressure roller 2 is poweredly connected to the feeding driver to convey the steel coil to be sheared.

[0026] Specifically, the flip-shear assembly 3 is mounted on the frame 1. Pressure rollers 2 are installed at both the front and rear of the flip-shear assembly 3 along the conveying direction of the steel coil. This ensures that the steel coil has corresponding pressure rollers 2 providing driving force for conveying before and after shearing, guaranteeing automatic feeding of the sheared steel coil without manual loading or unloading. Furthermore, when longitudinally cutting the steel coil, the pressure rollers 2 pull the steel coil relative to the flip-shear assembly 3, achieving continuous longitudinal shearing. This eliminates the need for any additional drives on the flip-shear assembly 3 besides the lifting and flipping drives, resulting in a more rational structural design. The flip-shear assembly 3 also includes a flipping frame 31, a rolling shearing section 32, and a transverse shearing section 33. During installation, both ends of the flipping frame 31 are rotatably mounted on the lifting frame 4, maintaining the balance of the flipping frame 31. Meanwhile, both lifting frames 4 are installed on the frame 1, enabling the two ends of the tilting frame 31 to be mounted on the frame 1 via the lifting frames 4. This allows the tilting frame 31 to be height-adjusted on the frame 1, providing conditions for the subsequent tilting of the tilting frame 31 and the application of shearing force. Simultaneously, a transverse shearing section 33 is provided on the upper part of the tilting frame 31, while a rolling shearing section 32 is rotatably installed on the lower part of the tilting frame 31. This allows the positions of the transverse shearing section 33 and the rolling shearing section 32 to be interchanged after the tilting frame 31 is tilted 180°. This ensures that both longitudinal and transverse shearing of the steel coil can be achieved through the tilting shearing assembly 3, ensuring that the longitudinal and transverse shearing parts of the steel coil are located in the same vertical plane, maintaining their positional consistency. This avoids the problems of high repetition, low efficiency, and material waste caused by the different positions of transverse and longitudinal shearing on the steel coil, saving costs and meeting the needs of large-scale production. In addition, the two sides of the middle part of the tilting frame 31 are respectively rotated and installed on the corresponding lifting frame 4, so that the tilting frame 31 can move up and down with the lifting frame 4, and can also rotate on the lifting frame 4 to realize the switching of the position of the horizontal shearing part 33 and the rolling shearing part 32.

[0027] More specifically, vertically arranged uprights 11 are provided on both sides of the frame 1. Preferably, the uprights 11 and the frame 1 are integral structures, which improves the stability of the uprights 11. At the same time, each upright 11 is provided with a vertically arranged sliding groove 12, and the two sides of the sliding groove 12 penetrate the inner and outer walls of the upright 11, respectively, providing conditions for the subsequent connection and installation of the tilting frame 31 located inside the upright 11 and the tilting drive located outside the upright 11 on the lifting frame 4. In addition, the two uprights 11 correspond one-to-one with the two lifting frames 4, and the lifting frames 4 are slidably disposed in the corresponding sliding grooves 12. That is, the sliding grooves 12 on the two uprights 11 provide guidance for the lifting frames 4 at both ends of the tilting frame 31, maintaining the stability of the tilting frame 31 when it is raised and lowered.

[0028] More specifically, each upright frame 11 includes an outer frame 111 and an inner frame 112. The slide chute 12 includes an outer slide rail 121 and an inner slide rail 122. The height of the outer frame 111 is higher than the height of the inner frame 112, providing a condition for the tilting frame 31 to disengage from the slide rail and tilt while the lifting frame 4 is still sliding within the slide rail on the upright frame 11. Furthermore, the outer slide rail 121 is located on the outer frame 111, and the inner slide rail 122 is located on the inner frame 112, with the inner slide rail 122 communicating with the outer slide rail 121, providing a condition for the tilting frame 31 to connect with the lifting frame 4. Furthermore, the upper end of the inner slide rail 122 extends through the top surface of the inner frame 112, facilitating the subsequent removal of the tilting frame 31 from the inner slide rail 122. This facilitates the tilting of the tilting frame 31 and avoids the upright frame 11 affecting its tilting. Additionally, during shearing, the tilting frame 31 re-enters the inner slide rail 122, maintaining its stability during shearing. This makes the structural design more rational. It is worth noting that a limiting step is provided between the inner slide rail 122 and the outer slide rail 121. The width of the outer slide rail 121 is greater than the width of the inner slide rail 122, thus confining the lifting frame 4 within the outer slide rail 121 and maintaining its stability during movement.

[0029] More specifically, the lifting frame 4 is slidably disposed within the outer slide rail 121 of the corresponding upright 11, so that the outer slide rail 121 can guide the lifting frame 4 to rise and fall, maintaining the stability of the lifting frame 4 during sliding. At the same time, the end of the tilting frame 31 is slidably disposed within the inner slide rail 122 of the corresponding upright 11, so that the inner slide rail 122 can guide the lifting movement of the tilting frame 31. After the lifting frame 4 rises to a predetermined height, the tilting frame 31 disengages from the inner slide rail 122. In addition, the lifting frame 4 is always maintained in the outer slide rail 121, which ensures that the lifting frame 4 can only rise and fall during the entire movement, and the tilting frame 31 can only rise and fall when moving within the inner slide rail 122, and can tilt after disengaging from the inner slide rail 122. This satisfies the usage requirements of changing the position of the rolling shearing part 32 and the horizontal shearing part 33 after tilting, and also ensures the stable use requirements of the inner slide rail 122 during shearing. The structural design is more reasonable.

[0030] More specifically, the lifting frame 4 includes a lifting slider 41 and a lifting driver. The lifting slider 41 is slidably placed in the outer slide rail 121. At the same time, the lifting driver is installed on the outer frame 111, and the drive shaft of the lifting driver is connected to the lifting slider 41. When the lifting driver is activated, it can drive the lifting slider 41 to move up and down in the outer slide rail 121 through its own drive shaft, thereby driving the tilting frame 31 to move up and down, so that the tilting frame 31 can enter and exit the inner slide rail 122 to meet the needs of tilting and shearing.

[0031] More specifically, a tilting drive is also installed on the lifting slider 41, so that the tilting drive can follow the lifting slider 41 to move up and down. In addition, an extended rotating shaft is provided at the end of the tilting frame 31, and the rotating shaft is rotatably mounted on the lifting slider 41 and powered by the tilting drive. Preferably, a gear reduction mechanism is provided between the tilting drive and the corresponding rotating shaft, which can provide greater torque to make the tilting frame 31 tilt smoothly, and the structural design is more reasonable.

[0032] More specifically, the horizontal shearing section 33 located on the upper part of the flipping frame 31 includes a horizontal cutter 331 and a connecting part 332. At this time, connecting parts 332 are provided at both ends of the horizontal cutter 331. When the horizontal cutter 331 is installed on the flipping frame 31, the two connecting parts 332 are respectively installed on both ends of the upper part of the flipping frame 31. Simultaneously, the blade of the horizontal cutter 331 is positioned facing outwards from the flipping frame 31, thus achieving the installation of the horizontal cutter 331 on the flipping frame 31. This also provides a condition for maintaining the blade of the horizontal cutter 331 aligned with the steel coil to be sheared after the flipping frame 31 is flipped.

[0033] More specifically, the connecting part 332 for mounting the horizontal cutter 331 onto the tilting frame 31 includes connecting blocks and threaded fasteners. During installation, the connecting blocks are first installed at both ends of the horizontal cutter 331. Preferably, the horizontal cutter 331 and the connecting blocks at both ends are welded together, resulting in higher structural strength. In addition, the two connecting blocks are respectively connected to the two ends of the upper part of the tilting frame 31 using threaded fasteners, that is, the connecting blocks are directly fixed to the tilting frame 31 using threaded fasteners including screws, making disassembly and assembly more convenient and facilitating the maintenance, repair, and replacement of the horizontal cutter 331.

[0034] More specifically, the rolling shearing section 32 located at the lower part of the tilting frame 31 includes a roller 321, a roller cutter 322, and a sleeve 323. At this time, both ends of the roller 321 are rotatably mounted to the lower ends of the tilting frame 31, thus achieving the installation of the roller 321 on the tilting frame 31. Simultaneously, the roller cutter 322 and the sleeve 323 are both fitted over the roller 321 and circumferentially limited by it, thus mounting the roller cutter 322 and the sleeve 323 onto the tilting frame 31 via the roller 321. It is worth noting that the width during longitudinal shearing can be adjusted by setting different numbers of roller cutters 322 and adjusting the spacing between adjacent roller cutters 322. Furthermore, the distance between adjacent roller cutters 322 can be adjusted by selecting an appropriate number and length of sleeves 323 to fill and limit the gap, thereby achieving adjustment of the distance between adjacent roller cutters 322, resulting in a more rational structural design. Preferably, the outer wall of the roller 321 is provided with a protrusion along its axial direction, and the inner walls of the cutter 322 and the sleeve 323 are provided with grooves corresponding to the protrusion, so that when the cutter 322 and the sleeve 323 are sleeved on the outside of the roller 321, circumferential positioning can be achieved through the protrusion and the groove, ensuring the relative stability of the cutter 322 and the sleeve 323 installed on the roller 321.

[0035] More specifically, an adjustment structure 311 is provided between one end of the roller 321 and the tilting frame 31. The adjustment structure 311 facilitates the subsequent assembly and disassembly of the hob 322 and the sleeve 323 on the roller 321. At this time, the adjustment structure 311 includes a telescopic rod and a locking pin. During installation, the telescopic rod is telescopically mounted on the tilting frame 31 and arranged radially along the roller 321. This allows the telescopic rod to adjust the distance between its end and the roller 321 by its own telescopic movement on the tilting frame 31. When the distance is large, it facilitates the assembly and disassembly of the hob 322 and the sleeve 323. When the distance is reduced to zero, the telescopic rod and the roller 321 are connected, thus supporting the roller 321. In addition, a locking pin is provided between the telescopic rod and the tilting frame 31, and one end of the telescopic rod is rotatably connected to the corresponding end of the roller 321. This locking pin temporarily fixes the telescopic rod after adjustment on the tilting frame 31, maintaining the stability of the telescopic rod during use and providing stable support for the roller 321 to ensure longitudinal shearing accuracy. Preferably, the tilting frame 31 has a telescopic hole along the radial direction of the roller 321, and one end of the telescopic rod is inserted into the telescopic hole. Furthermore, the telescopic rod has two insertion holes along its axial direction. The tilting frame 31 has a mating hole that connects to the telescopic hole and selectively engages with the two insertion holes. The locking pin is inserted into the mating hole and then into one of the insertion holes. Additionally, the end of the telescopic rod rotatably connected to the roller 321 is provided with an open clamp. The tightness of the clamp allows the roller 321 to be installed on and detached from the telescopic rod. That is, when it is necessary to adjust the cutter 322 and the sleeve 323, the clamp can be loosened first, allowing the roller 321 and the telescopic rod to be connected. Disengage, then unlock the locking pin, and retract the telescopic rod toward the telescopic hole, thereby fully exposing the end of the roller 321 and leaving a sufficiently large gap between it and the flipping frame 31. This facilitates the assembly and disassembly of the roller cutter 322 and the sleeve 323 on the roller 321, and provides convenience for subsequent adjustments to the number and position of the roller cutter 322 and the sleeve 323 on the roller 321. After adjustment, simply pull out the telescopic rod in the reverse direction and lock it with the locking pin, then connect the roller 321 to the telescopic rod with the clamp, thus connecting this end of the roller 321 to the flipping frame 31, improving the stability of the rolling shearing part 32, and meeting different shearing requirements.

[0036] More specifically, the pressure rollers 2 on the frame 1, positioned in front of and behind the flip-shear assembly 3, each include an upper pressure roller 21 and a lower pressure roller 22. During assembly, the upper pressure rollers 21 and lower pressure rollers 22 are arranged parallel to each other and distributed vertically in upper and lower layers. When pressing the steel coil, the steel coil passes between the upper pressure rollers 21 and lower pressure rollers 22. The rotation of the upper pressure rollers 21 and / or the lower pressure rollers 22 drives the steel coil to move, thus satisfying automatic loading and unloading operations. Simultaneously, during longitudinal shearing of the steel coil, they serve as the driving structure for pulling the steel coil relative to the roller cutter 322, resulting in a more rational structural design. It is worth noting that at least one of the upper pressure rollers 21 and lower pressure rollers 22 in the same group is connected to a motor, which drives the corresponding upper pressure roller 21 and / or lower pressure roller 22 to rotate, providing driving force.

[0037] More specifically, telescopic actuators are also provided at both ends of the upper pressure roller 21 and between the frame 1. When the telescopic actuators are moved in the vertical direction, the drive shaft of the telescopic actuators is connected to the end of the upper pressure roller 21. That is, the distance between the upper pressure roller 21 and the corresponding lower pressure roller 22 can be adjusted by the telescopic actuators, so as to adapt to the conveying of steel coils of different thicknesses. At the same time, it also provides convenience for adjusting the magnitude of the clamping force of the steel coil.

[0038] The steel coil shearing equipment provided in this embodiment includes a frame 1, a pressure roller 2, and a flipping shearing assembly 3. A lifting frame 4 is provided on the frame 1, and a flipping frame 31 of the flipping shearing assembly 3 is rotatably mounted on the lifting frame 4. At the same time, the pressure roller 2 is positioned in front of and behind the flipping shearing assembly 3. A rolling shearing section 32 and a transverse shearing section 33 are respectively provided on the upper and lower parts of the flipping frame 31. This allows the positions of the rolling shearing section 32 and the transverse shearing section 33 to be interchanged by flipping the flipping frame 31. As a result, the rolling shearing section 32 and the transverse shearing section 33 are located in the same vertical plane, ensuring that the longitudinal and transverse cutting points of the steel coil are in the same position on the steel coil. This effectively avoids the problems of high repetition, low efficiency, and serious waste caused by different transverse and longitudinal cutting positions, and meets the needs of large-scale production and manufacturing.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
