Description

Technical Field

[0001] This utility model relates to the field of silicon steel sheet processing technology, specifically to a track-type silicon steel sheet longitudinal shearing device with a displacement function. Background Technology

[0002] Silicon steel sheets, as an important soft magnetic alloy, are an indispensable key material in the power, electronics, and military industries, and are widely used in the manufacture of transformer, motor, and generator cores. Their processing quality directly affects electromagnetic conversion efficiency and equipment performance. In the processing of silicon steel sheets, longitudinal shearing is a crucial step, its purpose being to cut wide coils into one or more narrow strips according to product requirements.

[0003] Currently, the silicon steel sheet slitting equipment commonly used in the industry can be mainly classified into the following categories according to the method of adjusting the shearing width:

[0004] 1. Fixed Shearing Unit: This is the most traditional and common configuration. The core of this type of equipment—the shearing head—is rigidly fixed to the frame. Its shearing width is set during the initial installation and commissioning, suitable for continuous production of large batches of single-specification products. However, its inherent rigidity reveals its drawbacks when facing the demands of modern production with multiple varieties and small batches. When the shearing width needs to be changed, operators must perform an extremely cumbersome process: first, the entire line must be shut down; then, special tools must be used to disassemble the heavy cutter shaft, manually adjust the distance between the upper and lower cutter discs, or directly replace the cutter shaft assembly with one of a different specification; subsequently, precise cutter alignment and adjustment must be performed to ensure the meshing accuracy of the upper and lower cutter discs. This process is not only labor-intensive and requires high technical skills from operators, but also results in downtime of several hours or even longer, severely restricting the overall efficiency of the production line and increasing production cycles and costs.

[0005] 2. Adjustable Single-Head Cutter Head Equipment: To overcome the shortcomings of fixed units, a shearing head with an adjustable cutter head position has emerged. This type of equipment uses a slide rail, lead screw, or hydraulic locking mechanism on the cutter shaft to allow a single cutter head to move axially. Theoretically, this provides a degree of flexibility. However, in practical applications, the adjustment process still cannot be completed online and requires stopping the machine. Furthermore, ensuring the parallelism and relative positional accuracy between all cutter heads during adjustment is complex and prone to human error. More importantly, each adjustment essentially only changes the number and width combination of slits; the cutter head itself, as a whole, cannot achieve a fundamental switch between working modes such as "single cutting" and "multiple cuts," thus limiting its flexibility.

[0006] 3. Multi-head tandem shearing equipment: In some high-end applications, there is a solution where multiple shearing heads of different specifications are arranged in series on a single production line. Function switching is achieved by guiding the strip through different heads. While this solution reduces blade change time, it leads to a significant increase in equipment length, a large footprint, and high initial investment costs. Furthermore, the strip's repeated passage through different tension rollers and guide systems increases the risk of surface scratches and poses a significant challenge to precise tension control.

[0007] In summary, existing silicon steel sheet slitting equipment presents a difficult contradiction between the flexibility of switching shearing width, production efficiency, and ease of operation. Fixed equipment is highly efficient but inflexible; adjustable equipment is time-consuming and labor-intensive to adjust, and its flexibility improvement is limited; multi-head series equipment is costly and complex to control. With the increasing demand for "flexible manufacturing" in the industrial sector, the market urgently needs a new type of slitting device that can achieve rapid, precise, and automated switching between multiple preset shearing widths without sacrificing production efficiency. This utility model has emerged in response to this technological background. Utility Model Content

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide a track-type silicon steel sheet longitudinal shearing device with a switching function. It can quickly switch between two different shearing widths by rapidly switching the positions of two carriages, effectively improving production efficiency.

[0009] To achieve the aforementioned technical objective, the technical solution adopted by this utility model is as follows:

[0010] A track-type silicon steel sheet slitting device with a repositioning function includes an unwinding machine, a slitting device, and a winding machine arranged sequentially. The front end of the silicon steel sheet is wound on the unwinding machine, and the rear end is wound on the winding machine. The unwinding machine is used to unwind the silicon steel sheet, and the winding machine is used to wind up the sheared silicon steel sheet. The slitting device is used to slit the silicon steel sheet longitudinally. The slitting device includes a first carriage, a second carriage, and a track. A first shearing head is installed on the first carriage, and a second shearing head is installed on the second carriage. The first and second shearing heads have different shearing widths. The first and second carriages are mounted on the track and can move left and right along the track. By moving the first and second carriages, the first or second carriage can be selectively positioned between the unwinding machine and the winding machine to slit the silicon steel sheet longitudinally.

[0011] Furthermore, the first and second trolleys have the same structure, both including a trolley body, wheels, and a trolley drive motor. The trolley drive motor is mounted on the trolley body, and the wheels are mounted on the bottom of the trolley body and placed on the track. The trolley drive motor is connected to the wheels for transmission, so that the wheels can drive the trolley body to move along the track. The first shearing head and the second shearing head are respectively mounted on the trolley body of the first and second trolleys.

[0012] Furthermore, the first shearing head includes a left mounting bracket, a right mounting bracket, a shearing motor, an upper shearing roller, a lower shearing roller, and a cutter. The left and right mounting brackets are respectively installed on the left and right sides of the vehicle body. The upper and lower shearing rollers are arranged laterally, with their left ends rotatably mounted on the left mounting bracket and their right ends rotatably mounted on the right mounting bracket. The upper shearing roller is located above the lower shearing roller. The shearing motor is connected to both the upper and lower shearing rollers and can drive them to rotate in opposite directions. The cutter is ring-shaped, with two cutters installed on each of the upper and lower shearing rollers. The cutters on the upper and lower shearing rollers are aligned vertically and can cooperate to cut the silicon steel sheet located between them. The distance between the two cutters on the same shearing roller is the shearing width of the shearing head.

[0013] Furthermore, both ends of the upper and lower shearing rollers are rotatably connected to the corresponding mounting brackets via roller rods. Synchronous gears are installed on the roller rods of both the upper and lower shearing rollers. The synchronous gears of the upper and lower shearing rollers mesh with each other, thereby enabling the upper and lower shearing rollers to rotate in opposite directions. The drive shaft of the shearing motor is fixedly connected to the roller rod at one end of the upper or lower shearing roller.

[0014] Furthermore, both the upper and lower shearing rollers have several equally spaced circumferential mounting grooves on their circumferential surfaces, and the cutter is installed in the circumferential mounting grooves.

[0015] Furthermore, the cutter includes a first cutter unit and a second cutter unit. Both the first cutter unit and the second cutter unit are semi-circular and are assembled together to form a ring structure. Both the first cutter unit and the second cutter unit include a cutter holder and a cutter head. The cutter holder can be fixed in the circumferential mounting groove, and the cutter head is fixed on the outside of the cutter holder.

[0016] Furthermore, the tool holder is provided with threaded holes, and mating holes are provided on both sides of the circumferential mounting groove. The bolt passes through both the threaded holes and the mating holes to fix the tool holder in the circumferential mounting groove.

[0017] Furthermore, the structure of the second shearing head is the same as that of the first shearing head, but the shearing width of the blades installed on the two are different.

[0018] Furthermore, the winding machine includes a winding motor and a winding shaft. The winding motor is connected to the winding shaft in a drive connection, and the winding motor can drive the winding shaft to rotate, thereby moving the silicon steel sheet from the unwinding machine to the winding machine.

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

[0020] 1. This utility model achieves rapid switching between two product specifications by setting two independent trolley-type cutter heads with different shearing widths and moving them on a track for repositioning. It eliminates the need for cumbersome cutter adjustments and changes on a single cutter head, significantly reducing production line downtime and substantially improving production efficiency.

[0021] 2. The trolley is driven by a motor, ensuring smooth and accurate movement; the shearing head adopts an upper and lower roller structure, providing high shearing force and excellent results; the cutter is designed to be detachable, facilitating installation, replacement, and maintenance.

[0022] 3. By setting multiple circumferential mounting grooves on the shearing roller, the position of the cutter can be flexibly adjusted, making the shearing width of each carriage also adjustable, thus enhancing the overall adaptability of the equipment. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the application is described and illustrated below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. All other embodiments obtained by those skilled in the art based on the embodiments provided in this application without inventive effort are within the scope of protection of this application.

[0029] Obviously, the accompanying drawings described below are merely some examples or embodiments of this application. Those skilled in the art can apply this application to other similar scenarios based on these drawings without any inventive effort. Furthermore, it is understood that although the efforts made in this development process may be complex and lengthy, for those skilled in the art related to the content disclosed in this application, any changes to design, manufacturing, or production based on the technical content disclosed in this application are merely conventional technical means and should not be construed as insufficient disclosure of the content of this application.

[0030] like Figure 1 As shown, the track-type silicon steel sheet slitting device with a repositioning function of this utility model mainly consists of three parts: an unwinding machine 1, a slitting device 2, and a winding machine 3. The silicon steel sheet 7 is unwound from the unwinding machine 1, longitudinally slit by the slitting device 2, and finally wound up by the winding machine 3.

[0031] The core of the slitting device 2 consists of a first trolley 4 and a second trolley 5 mounted on the same track 21. The first trolley 4 is equipped with a first shearing head 41, and the second trolley 5 is equipped with a second shearing head 51. The shearing widths of the two shearing heads are preset to be different. Figure 2 As shown, the first carriage 4 is in the working position (between the unwinder 1 and the rewinder 3) and is cutting the silicon steel sheet 7; while the second carriage 5 is in the standby position next to it. When it is necessary to change the cutting width, simply start the carriage drive motor 44 to drive the first carriage 4 out of the working position and at the same time drive the second carriage 5 into the working position. The whole process is quick and simple.

[0032] like Figure 2 As shown, the first trolley 4 and the second trolley 5 have symmetrical and identical structures. They both include a trolley body 42, wheels 43, and a trolley drive motor 44. The wheels 43 travel on the track 21 and are driven by the trolley drive motor 44. The shearing blade is fixedly mounted on the trolley body 42.

[0033] Combination Figure 2 , Figure 3 and Figure 4Taking the first shearing head 41 as an example, its structure is described in detail. It includes left and right mounting brackets fixed to the vehicle body 42. The upper shearing roller 41d and the lower shearing roller 41e are supported and rotatably spanned between the left and right mounting brackets by roller rods. The ends of the roller rods of the upper shearing roller 41d and the lower shearing roller 41e are equipped with meshing synchronous gears 41f to ensure that the two rollers rotate in opposite directions. The shearing motor 41c drives the entire shearing system by driving one of the roller rods.

[0034] Two annular cutters 6 are mounted on the upper shearing roller 41d, and two corresponding annular cutters 6 are mounted on the lower shearing roller 41e. Figure 4 As shown, the upper and lower cutters 6 are aligned with each other to form a shearing pair for shearing the silicon steel sheet 7 passing through. The axial distance L between the two cutters 6 on the same shearing roller determines the shearing width of the cutter head. The structure of the second shearing cutter head 51 is exactly the same, but the spacing L' between the cutters 6 mounted on it is different from L, thus achieving different shearing widths.

[0035] For the installation method of cutter 6, please refer to Figure 3 and Figure 4 The cutter 6 is composed of a first cutter unit 61 and a second cutter unit 62, and is fixed to the circumferential mounting groove 41g of the shearing roller by bolts. This split structure facilitates disassembly and replacement. The cutter head 64 is fixed on the cutter holder 63 and is the part that directly performs the shearing.

[0036] The winding machine 3 serves as a power source, and its winding motor drives the winding shaft to rotate, thereby pulling the silicon steel sheet 7 to move continuously from the unwinding machine 1 to the winding machine 3.

[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
