Description

Technical Field

[0001] This invention relates to the field of metal processing technology, and in particular to a high-precision longitudinal and transverse shearing device for transformer silicon steel sheets. Background Technology

[0002] The high-precision longitudinal and transverse shearing device for transformer silicon steel sheets refers to a composite CNC machining production equipment that integrates longitudinal slitting and transverse shaping shearing functions. It is designed specifically for processing silicon steel sheets for transformer cores. Its core feature is to automatically process silicon steel coils into sheet-like units that meet the core design requirements and can be directly stacked with micron-level size and shape control precision.

[0003] In existing equipment, most methods involve independent manual adjustment of a single tool holder or simultaneous coarse adjustment of multiple tool holders followed by fine adjustment of a single tool. When batch processing workpieces of different specifications, frequent adjustments to the spacing between the tool holders are necessary. Manual adjustment relies on operator experience, resulting in low efficiency and an inability to guarantee perfectly consistent tool holder spacing, which can easily lead to dimensional deviations. While simultaneous coarse adjustment can improve efficiency, it lacks a fine-tuning mechanism that progressively adjusts to a tool holder reference, failing to accurately compensate for precision losses caused by equipment assembly errors and tool holder wear. Furthermore, the lack of real-time distance verification means that the accuracy of the tool holder spacing after adjustment is difficult to guarantee. Additionally, the tool holders and tool shafts often use a sliding connection with a mechanical locking structure, making it impossible to quantify and monitor the locking force. Insufficient locking can lead to tool holder displacement during shearing, while excessive locking can cause abnormal sliding friction resistance, further affecting adjustment accuracy and shearing stability. In addition, a large amount of metal dust is generated during the cutting process of metal blades. Some of the dust is at a high temperature and carries sparks. The dust cleaning devices of existing equipment are mostly fixed-position exhaust structures, which cannot follow the movement of the blade holder to achieve close-range and accurate capture. The dust is easily diffused into the equipment and the working environment, which not only pollutes the environment but also endangers the health of operators.

[0004] Therefore, this application provides a high-precision longitudinal and transverse shearing device for transformer silicon steel sheets to meet the requirements. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a high-precision longitudinal and transverse shearing device for transformer silicon steel sheets, so as to solve the problems of existing devices that are difficult to quickly adjust the distance between the blade holders, cannot detect the locking force between the blade holder and the blade shaft after adjustment, and cannot accurately extract the dust generated during blade cutting according to the specific position of the blade holder.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A high-precision longitudinal and transverse shearing device for transformer silicon steel sheets includes: a longitudinal and transverse shearing equipment body; a lower cutter shaft is installed at the bottom of one side of the longitudinal and transverse shearing equipment body; a plurality of lower cutter seats are installed on the outer wall of the lower cutter shaft; mounting seats are symmetrically arranged at the top of one side of the longitudinal and transverse shearing equipment body; an upper cutter shaft is installed between two mounting seats; an upper cutter seat is installed on the outside of the upper cutter shaft; and a transverse shearing mechanism is installed at the top of the other side of the longitudinal and transverse shearing equipment body; a coarse adjustment component is arranged on the outer side of the top of the upper cutter shaft, which is used to coarsely adjust the distance between the upper cutter seats; a plurality of fine adjustment components are alternately arranged inside the coarse adjustment component, which is used to finely adjust the distance between the upper cutter seats; and a cleaning component is arranged inside the plurality of fine adjustment components, which is used to clean the dust generated during cutting in real time.

[0007] Optionally, the coarse adjustment assembly includes two connecting rods, which are disposed on both sides above the upper cutter shaft. One end of the two connecting rods is fixed to each other, and the fixed ends of the two connecting rods are fixedly connected to two first hydraulic rods. The other ends of the two first hydraulic rods are fixedly connected to a mounting base on one side.

[0008] Optionally, the coarse adjustment assembly further includes a plurality of connecting sleeves, which are alternately fixed to the outer walls of the two connecting rods. Each connecting sleeve is fitted with a spring on its outer wall, and the top end of each spring is fixedly connected to the top outer wall of the connecting sleeve.

[0009] Optionally, the coarse adjustment component further includes a plurality of first serrated protective sleeves, which are respectively fixedly connected to the bottom end of the connecting sleeve. The bottom end of each spring is fixedly connected to the top outer wall of the first serrated protective sleeve, and a first electromagnet is embedded in the bottom end of each first serrated protective sleeve.

[0010] Optionally, the coarse adjustment component further includes a plurality of second serrated protective sleeves, which are respectively disposed at the bottom end of the first serrated protective sleeve. The number of the second serrated protective sleeves is the same as that of the first serrated protective sleeve, and they correspond one-to-one. Each second serrated protective sleeve has a second electromagnet embedded in its top end.

[0011] Optionally, the fine-tuning component includes a second hydraulic rod, which is fixedly connected to the bottom end of the second serrated protective sleeve. Slip rings are slidably connected to the outer walls of both ends of the upper tool holder. U-shaped rods are symmetrically fixed between the two slip rings, and one side of the U-shaped rod is fixedly connected to the output end of the second hydraulic rod.

[0012] Optionally, the fine-tuning component also includes a laser rangefinder, which is installed on the top outer wall of one side slip ring. Hydraulic locking sleeves are installed on the inner walls of both ends of the upper tool holder, and piezoelectric sensors are embedded in the inner walls of both hydraulic locking sleeves.

[0013] Optionally, the cleaning assembly includes a plurality of cleaning nozzles, each of which is fixed to the top of a U-shaped rod. The number of cleaning nozzles and the number of U-shaped rods are the same and correspond one-to-one.

[0014] Optionally, the cleaning assembly further includes several hoses, each hose being connected to the inside of the cleaning nozzle. Each hose has a connecting rigid tube at its top end, and the two ends of the connecting rigid tubes are fixed to each other. Corrugated tubes are connected between the connecting rigid tubes, and every two connecting rigid tubes are fixedly connected to a slip ring via a rod.

[0015] Optionally, the cleaning assembly further includes a collection box, which is installed on the top side of one side of the slitting and transverse shearing equipment body. A collection frame is slidably connected inside the collection box, and a cyclone separator is installed on the top of the collection box. The connecting rigid pipe on one side is connected to the cyclone separator through a pipe. The top of the cyclone separator is connected to the collection frame through a pipe. A vacuum pump is connected to the collection frame through a pipe.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, the graded adjustment structure combining coarse and fine adjustment components effectively compensates for the shortcomings of existing equipment, such as low efficiency of manual adjustment and lack of fine adjustment mechanism in synchronous coarse adjustment. In the coarse adjustment stage, the first hydraulic rod drives the connecting rod, which, combined with the electromagnet attraction, forms a rigid connection body, which can drive all upper tool holders to move synchronously to the target range, greatly reducing the time lost during manual adjustment. In the fine adjustment stage, the adjacent calibrated upper tool holders are used as a reference, and the second hydraulic rod realizes progressive fine adjustment of each upper tool holder. With the help of a laser rangefinder to verify the spacing in real time, the precision loss caused by equipment assembly errors and upper tool holder wear is accurately compensated, ensuring that the spacing of each upper tool holder is completely consistent, reducing the deviation of processing dimensions, and meeting the requirements of high-precision shearing. At the same time, by utilizing the telescopic characteristics of the connecting sleeve, the buffering effect of the spring, and the split structure of the electromagnet attraction, the reset purpose can be quickly achieved while meeting the adjustment requirements of the spacing of multiple specifications of tool holders, reducing the error caused by manual intervention and improving the practicality and operability of the equipment.

[0017] In the above solution, a hydraulic locking sleeve, in conjunction with an embedded piezoelectric sensor, precisely monitors the locking degree between the upper blade holder and the upper blade shaft. This prevents the upper blade holder from shifting during shearing due to insufficient locking, or from causing abnormal sliding friction resistance due to excessive locking. Simultaneously, it monitors the radial force transmitted from the blade shaft to the upper blade holder in real time during shearing, and monitors the sliding friction resistance between the upper blade holder and the blade shaft during adjustment, providing timely feedback on the blade's working status and movement smoothness. This further improves adjustment accuracy and the stability of the shearing operation, reduces errors, and enhances the precision of the equipment. In this solution, the cleaning nozzle, fixed to a U-shaped rod, moves synchronously with the upper blade holder, enabling close-range, precise collection of dust from each blade holder's cutting area. This reduces dust diffusion at the source. The combination of rigid and corrugated pipes adapts to positional changes during blade holder movement. Combined with the efficient separation of a cyclone separator and the filtration and storage of the collection frame, it can quickly handle high-temperature metal dust and sparks generated during cutting. This prevents dust from contaminating internal components and affecting their lifespan, while also preventing dust spread, greatly improving the working environment and further reducing the health hazards of dust to operators.

[0020] As shown in the figure, specific structures and devices are labeled in the figure to clearly illustrate the structure of the embodiments of the present invention. However, this is only for illustrative purposes and is not intended to limit the present invention to the specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0021] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0022] like Figures 1 to 8As shown, an embodiment of the present invention provides a high-precision longitudinal and transverse shearing device for transformer silicon steel sheets, comprising: a longitudinal and transverse shearing equipment body 1, a lower cutter shaft 5 installed at the bottom of one side of the longitudinal and transverse shearing equipment body 1, a plurality of lower cutter seats 6 installed on the outer wall of the lower cutter shaft 5, mounting seats 2 symmetrically arranged at the top of one side of the longitudinal and transverse shearing equipment body 1, an upper cutter shaft 3 installed between two mounting seats 2, and an upper cutter seat 4 installed on the outside of the upper cutter shaft 3, since the lower cutter seat 6 requires fewer adjustments and can be adjusted according to traditional methods, a transmission roller is installed between the longitudinal shearing mechanism 10 composed of the upper cutter seat 4 and the lower cutter seat 6 for conveying materials. A horizontal shearing mechanism 10 is installed on the top of the other side of the shearing equipment body 1. The horizontal shearing mechanism 10 consists of horizontal shears and a cylinder. The output end of the cylinder is fixedly connected to the end of the horizontal shears. The horizontal shears are driven to move downward through the output end of the cylinder to cut the material. A coarse adjustment component 7 is provided on the outer side of the top of the upper blade shaft 3. The coarse adjustment component 7 is used to coarsely adjust the distance between the upper blade holders 4. Several fine adjustment components 8 are alternately arranged inside the coarse adjustment component 7. The fine adjustment components 8 are used to finely adjust the distance between the upper blade holders 4. A cleaning component 9 is provided on the inner side of the several fine adjustment components 8. The cleaning component 9 is used to clean the dust generated during cutting in a timely manner.

[0023] like Figures 1 to 7As shown, the coarse adjustment assembly 7 includes two connecting rods 701, which are positioned on both sides above the upper cutter shaft 3. One end of each connecting rod 701 is fixed to the other, and the fixed ends of the two connecting rods 701 are fixedly connected to two first hydraulic rods 708. The other ends of the two first hydraulic rods 708 are fixedly connected to a mounting base 2 on one side. The coarse adjustment assembly 7 also includes several connecting sleeves 702, which are alternately fixed to the outer walls of the two connecting rods 701. The connecting sleeves 702 are telescopic sleeves used to provide rigid support when the springs 703 are compressed or stretched. Each connecting sleeve 702 has a spring 703 fitted on its outer wall, and the top end of each spring 703 is fixedly connected to the top outer wall of the connecting sleeve 702. The coarse adjustment assembly 7 also includes several first serrated protective sleeves 704, which are respectively fixedly connected to the connecting sleeves 702. At the bottom end, the bottom end of each spring 703 is fixedly connected to the outer wall of the top end of the first serrated protective sleeve 704. The bottom end of each first serrated protective sleeve 704 is embedded with a first electromagnet 705. The coarse adjustment component 7 also includes several second serrated protective sleeves 706. Several second serrated protective sleeves 706 are respectively set at the bottom end of the first serrated protective sleeve 704. The contact surfaces of the first serrated protective sleeve 704 and the second serrated protective sleeve 706 are serrated. After the first electromagnet 705 and the second electromagnet 707 are attracted together, the serrated surfaces of the first serrated protective sleeve 704 and the second serrated protective sleeve 706 mesh together, thereby increasing the friction and increasing the rigidity of the connection. The number of second serrated protective sleeves 706 is the same as that of the first serrated protective sleeve 704, and they correspond one-to-one. The top end of each second serrated protective sleeve 706 is embedded with a second electromagnet 707.

[0024] like Figures 3 to 8As shown, the fine-tuning component 8 includes a second hydraulic rod 801, which is fixedly connected to the bottom end of the second serrated protective sleeve 706. Slip rings 803 are slidably connected to the outer walls of both ends of the upper tool holder 4. The slip rings 803 are slidably connected to the upper tool holder 4, ensuring relative stability when the upper tool holder 4 rotates, thus preventing interference with its rotation. A U-shaped rod 802 is symmetrically fixed between the two slip rings 803. One side of the U-shaped rod 802 is fixedly connected to the output end of the second hydraulic rod 801. The fine-tuning component 8 also includes a laser rangefinder 804, which is mounted on the top outer wall of one slip ring 803. A laser rangefinder 804 is used to measure the distance between each upper blade holder 4, which facilitates calibration. Hydraulic locking sleeves 805 are installed on the inner walls of both ends of the upper blade holder 4. Piezoelectric sensors 806 are embedded in the inner walls of both hydraulic locking sleeves 805. The piezoelectric sensors 806 are used to measure the pressure between the hydraulic locking sleeves 805 and the upper blade shaft 3 to ensure that the hydraulic locking sleeves 805 are properly locked. At the same time, the piezoelectric sensors 806 detect the radial force transmitted to the upper blade holder 4 by the blade shaft during the shearing process to monitor the state of the blade during cutting. During fine adjustment, the frictional resistance of the upper blade holder 4 during sliding is monitored to ensure smooth movement.

[0025] like Figures 2 to 6As shown, the cleaning assembly 9 includes several cleaning nozzles 901, each fixed to the top of a U-shaped rod 802. The cleaning nozzles 901 are tilted, with their openings facing the cutting position of the upper blade holder 4, facilitating timely removal of cutting dust. Since the cleaning nozzles 901 are fixed to the U-shaped rod 802, they move the same distance when the upper blade holder 4 moves, ensuring accurate dust removal from each blade's cutting action. The number of cleaning nozzles 901 and U-shaped rods 802 is identical and corresponds one-to-one. The cleaning assembly 9 also includes several flexible hoses 902, each connected to the interior of a cleaning nozzle 901. Each flexible hose 902 has a connecting rigid tube 903 at its top, with the two ends of the connecting rigid tubes 903 fixed together. The multiple connecting rigid tubes 903 are connected to each other. All are connected to a corrugated pipe 904, which is used to stretch or compress the cleaning nozzle 901 when it moves to ensure smooth movement of the cleaning nozzle 901. Each pair of connecting rigid pipes 903 is fixedly connected to a slip ring 803 by a rod. The cleaning assembly 9 also includes a collection box 906, which is installed on the top side of one side of the longitudinal and transverse shearing equipment body 1. A collection frame 907 is slidably connected inside the collection box 906. A cyclone separator 905 is installed on the top of the collection box 906. The rigid pipe 903 on one side is connected to the cyclone separator 905 through a pipe. The top of the cyclone separator 905 is connected to the collection frame 907 through a pipe. A metal dust filter is installed on the inner wall of the collection frame 907 to filter metal dust and protect the vacuum pump 908. The collection frame 907 is connected to the vacuum pump 908 through a pipe.

[0026] The working principle of the technical solution provided by this invention is as follows: During operation, when the material is conveyed between the upper cutter holder 4 and the lower cutter holder 6, the upper cutter shaft 3 is driven, which in turn drives the upper cutter holder 4 to rotate. Simultaneously, the lower cutter shaft 5 is driven, which in turn drives the lower cutter holder 6 to rotate, thereby causing the blades to rotate and thus achieving longitudinal cutting of the material. After longitudinal cutting, the material is conveyed to the bottom of the cross-cutting mechanism 10 via the conveyor roller, and then the cross-cutting mechanism 10 is driven to perform transverse cutting of the material.

[0027] Furthermore, when it is necessary to increase the size of the material to be cut, the hydraulic locking sleeve 805 is unlocked, causing the upper cutter holder 4 to slide. All the first electromagnets 705 and second electromagnets 707 are energized, causing the first electromagnet 705 to move downwards under the attraction. The first electromagnet 705 drives the first serrated protective sleeve 704 downwards, which in turn drives the connecting sleeve 702 downwards. Simultaneously, the spring 703 is stretched, thus achieving the attraction and fixation of the first electromagnet 705 and the second electromagnet 707. At the same time, the serrated surfaces of the first serrated protective sleeve 704 and the second serrated protective sleeve 706 fit together, forming a rigid connection. Then, the first hydraulic rod 708 is activated, driving the connecting rod 701 to move through its output end. The connecting rod 701 then moves all the rigid connections containing the connecting sleeves 702 synchronously to the approximate target position range, thereby moving the upper cutter holder 4 to the approximate target position range. After completing the synchronous adjustment, the upper cutter holder... Using the mounting base 2 at the end of the first upper tool holder 4 as a reference surface, the first upper tool holder 4 is calibrated. At this time, the distance to the current position is measured by the laser rangefinder 804 at the position of the first upper tool holder 4. The distance that the first upper tool holder 4 needs to be adjusted is calculated by the difference between the measured distance and the target position. The second hydraulic rod 801 at the position of the first upper tool holder 4 is activated. The output end of the second hydraulic rod 801 drives the U-shaped rod 802 to move, and then the U-shaped rod 802 drives the slip ring 803 to move. The upper tool holder 4 is moved to the target position. Then, using the first adjusted upper tool holder 4 as a reference, the second upper tool holder 4 is adjusted, and so on, until all upper tool holder 4 are adjusted. After all the upper tool holder 4 are adjusted, the upper tool holder 4 is locked by the hydraulic locking sleeve 805, so that the upper tool holder 4 and the upper tool shaft 3 are fixed together again. At the same time, the locking force of the hydraulic locking sleeve 805 is measured by the piezoelectric sensor 806 to ensure the stability of the upper tool holder 4 and the upper tool shaft 3.

[0028] Furthermore, after the distance adjustment is completed, the material is transferred between the upper cutter holder 4 and the lower cutter holder 6, and then the material is cut by the blades on the upper cutter holder 4 and the lower cutter holder 6. At this time, the vacuum pump 908 is started, so that the cleaning nozzle 901 generates suction and sucks up the dust generated during the cutting of each cutter holder. The dust enters the hose 902 through the cleaning nozzle 901, and then the dust is guided into the combined pipe formed by the connecting rigid pipe 903 and the corrugated pipe 904 through the hose 902. Then the dust is guided into the cyclone separator 905 through the combined pipe. The cyclone separator 905 separates the dust, so that the large dust particles fall into the collection frame 907 through the lower opening of the cyclone separator 905. At the same time, the gas containing small particles is separated and output to the collection frame 907 through the pipe for secondary separation, thereby realizing the collection of dust.

[0029] Furthermore, when all upper tool holders 4 need to be reset, the hydraulic locking sleeve 805 is unlocked, causing the upper tool holders 4 to be in a sliding state. The second hydraulic rod 801 is activated, causing each second hydraulic rod 801 to drive the upper tool holder 4 at its output end to reset one by one. Then, the first hydraulic rod 708 is activated, and the connecting rod 701 is reset through its output end. Then, the connecting rod 701 drives the rigid connecting body where the connecting sleeve 702 is located to reset. Thus, the rigid connecting body where the connecting sleeve 702 is located drives all upper tool holders 4 to move to their original positions. At this time, the first electromagnet 705 and the second electromagnet 707 are de-energized. The first electromagnet 705 moves upward under the action of the spring 703 and separates from the second electromagnet 707. Then, the hydraulic locking sleeve 805 is used to lock the upper tool holders 4 and the upper tool shaft 3, thereby completing the reset of the entire upper tool holder 4.
