Description

Technical Field

[0001] This invention relates to the field of silicon steel sheet cutting technology, specifically to a transformer silicon steel sheet fixed-length cutting device with adaptive clamping. Background Technology

[0002] The transformer core is made of stacked silicon steel sheets. The cutting quality of the silicon steel sheets directly affects the practical performance of the transformer. If the clamping force is insufficient during cutting, the thin sheet will bend and deform upwards when the blade cuts in (similar to how paper curls when cutting thin paper with scissors), causing the actual cutting position to deviate and the dimensions to be out of tolerance. If the clamping force is too large (for thin sheets), the pressure plate itself will press permanent indentations (marks) on the surface of the sheet, damaging the surface insulation layer.

[0003] Existing devices mostly use a fixed clamping structure, which makes it difficult to adaptively adjust the clamping force according to changes in the thickness of silicon steel sheets and fluctuations in incoming materials, resulting in unstable clamping effect. Secondly, existing devices mostly achieve fixed length measurement through the displacement of mechanical blocks, which is cumbersome to adjust and seriously affects cutting efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an adaptive clamping transformer silicon steel sheet fixed-length cutting device to solve the problems of existing technologies that cannot adaptively adjust the clamping force according to the thickness of the silicon steel sheet and the cumbersome fixed-length measurement.

[0006] The cutting device is connected to a main controller to receive electrical signals and issue control commands. When it is necessary to cut silicon steel sheets, the silicon steel sheets are first pulled through the space between the clamping rod and the bottom rod, and then the silicon steel sheets are transported by the conveying component. During the transport, the length-fixing component detects the length of the silicon steel sheets that have passed through the cutting component in real time. When the specified cutting length is reached, the length-fixing component sends an electrical signal to control the clamping component to clamp, and then the cutting is carried out. During clamping, the base rod is fixed, and the clamping slider moves along the clamping slide rail towards the base rod. When the contact sensor contacts the silicon steel sheet, it sends an electrical signal to stop the clamping slide rail. The thickness of the silicon steel sheet is determined based on the downward movement distance of the clamping slider, and the clamping component is controlled to apply the corresponding clamping force. Different clamping forces can be adaptively adjusted according to different silicon steel sheet thicknesses, which can avoid indentations, curling at the cut, and secondary burrs caused by unsuitable clamping force, thus effectively improving the cutting quality.

Multiple contact rollers are evenly installed on the support seats.

[0008] As a preferred technical solution, an electromagnetic block is located below the length measuring block, and the electromagnetic block is L-shaped.

[0009] As a preferred technical solution, the unloading component includes an unloading slide rail, an unloading slide rail slider, an unloading rod, a return spring, an unloading auxiliary slider, a wedge block, and a slot; Two feeding slide rails are symmetrically installed on the cutting table.

A vertical screw is rotatably mounted on the vertical screw seat and threadedly engaged with a support seat. A horizontal screw is rotatably mounted on the horizontal screw seat. A driving bevel gear is provided at the end of the vertical screw, and a driven bevel gear is mounted at the end of the horizontal screw. The driving bevel gear and the driven bevel gear mesh. A smooth rod is mounted on the horizontal screw seat, and a screw slider is slidably mounted on the smooth rod. The screw slider engages with the horizontal screw. A reset block is slidably mounted on the support seat, and a connecting rod is mounted on the reset block. The connecting rod is slidably connected to the reset block.

[0011] As a preferred technical solution, the cutting table is provided with auxiliary components, which include auxiliary slide rails, auxiliary slide rail sliders, misalignment rods, and electric suction cups; An auxiliary slide rail is installed on the cutting table, an auxiliary slide rail slider is provided on the auxiliary slide rail, an offset rod is provided on the auxiliary slide rail slider, and an electric suction cup is installed at the end of the offset rod.

[0012] As a preferred technical solution, the auxiliary component further includes a detection slider slidably mounted on the auxiliary slide rail, the detection slider being connected to the auxiliary slide rail slider via a detection spring, the misalignment rod being mounted on the detection slider, and a pressure sensor being mounted on one end of the detection spring.

[0013] As a preferred technical solution, the extrusion component is an inflatable airbag, and the inflatable airbag is externally connected to an inflation component and a pressure sensor.

[0014] As a preferred technical solution, the extruded component is made of an elastic material.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The clamping force can be adaptively adjusted according to the different thicknesses of silicon steel sheets, which can avoid indentation, curling and secondary burrs caused by unsuitable clamping force, thus effectively improving the cutting quality.

[0016] 2. The distance sensor will detect the distance between the length measuring block and the distance sensor in real time, and indirectly measure the length of the silicon steel sheet that is about to be cut. When the length reaches the specified distance, the distance sensor will send an electrical signal to start the pressing and cutting operation, which can improve the cutting accuracy and further ensure the cutting quality.

[0017] 3. After cutting, the material feeding auxiliary slider moves down while driving the support seat to slide to both sides. At this time, the silicon steel sheet slides down, realizing autonomous downward movement and feeding. This improves processing efficiency while reducing the free fall distance of the silicon steel sheet, reducing damage. Secondly, it can simplify the feeding operation and improve efficiency.

[0018] 4. When the screw slider moves, it will push the measuring block to move closer to the cutting part through the connecting rod and the reset block. This ensures that the measuring block can contact the end of the silicon steel sheet before reaching the cutting length when the silicon steel sheet is fed in the next time, thus ensuring the accuracy of fixed-length cutting and further guaranteeing the cutting quality.

[0019] 5. The auxiliary component allows the cutting end to move out of the bottom rod, and then the electric suction cup is reset to carry out the unloading process. This ensures that the silicon steel sheet is removed from the cutting station, achieving unobstructed unloading while avoiding scratches on the extruded parts by the end of the silicon steel sheet, further ensuring the cutting quality.

[0020] 6. When assisting in pushing silicon steel sheets, different faults can be detected, making it easier for workers to carry out repairs, shortening repair and inspection time, and improving production efficiency. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example: Figures 1-7 As shown, the present invention provides a technical solution for an adaptive clamping transformer silicon steel sheet fixed-length cutting device. The adaptive clamping transformer silicon steel sheet fixed-length cutting device includes a cutting table 1, a conveying component 2 and a cutting guide rail 3 installed on the cutting table 1, a cutting slide 4 slidably arranged on the cutting guide rail 3, a cutting component 5 installed on the cutting slide 4, a clamping component 6 and a fixed-length component 7 arranged on the cutting table 1, and the fixed-length component 7 includes a feeding component 8; The clamping component 6 includes a clamping slide rail 601, a clamping slider 602, a bottom rod 603, a clamping rod 604, a contact sensor 605, and a pressing component 606; A clamping slide rail 601 is installed on the cutting table 1. A clamping slider 602 is provided on the clamping slide rail 601. A clamping rod 604 is installed on the clamping slider 602. A bottom rod 603 is installed on the cutting table 1. A contact sensor 605 and a pressing component 606 are installed on the side of the clamping rod 604 facing the bottom rod 603.

[0025] The cutting device is connected to a main controller to receive electrical signals and issue control commands. When it is necessary to cut silicon steel sheets, the silicon steel sheets are first pulled through the space between the clamping rod 604 and the bottom rod 603, and then the silicon steel sheets are transported through the conveying component 2. During the transport, the length-fixing component 7 detects the length of the silicon steel sheets that have passed through the cutting component 5 in real time. When the specified cutting length is reached, the length-fixing component 7 sends an electrical signal to control the clamping component 6 to clamp, and then the cutting is carried out. During clamping, the base rod 603 is fixed, and the clamping slider 602 moves along the clamping slide rail 601 towards the base rod 603. When the contact sensor 605 contacts the silicon steel sheet, it will send an electrical signal to control the clamping slide rail 601 to stop running. The thickness of the silicon steel sheet is determined based on the downward movement distance of the clamping slider 602, and the clamping component 6 is controlled to apply the corresponding clamping force. Different clamping forces can be adaptively adjusted according to different silicon steel sheet thicknesses, which can avoid indentation, curling at the cut, and secondary burrs caused by unsuitable clamping force, thus effectively improving the cutting quality.

[0026] The length-fixing component 7 includes a support base 701, a length-fixing chute 702, a length measuring block 703, a distance sensor 704, and a contact roller 705; Two support seats 701 are symmetrically arranged on the cutting table 1. A fixed length groove 702 is opened on the support seat 701. A length measuring block 703 is slidably installed in the fixed length groove 702. A distance sensor 704 is installed on the side of the support seat 701 away from the cutting part 5. Multiple contact rollers 705 are evenly installed on the support seat 701.

[0027] The support base 701 is integrally formed with a C-shaped groove 707 with an opening facing the cutting part 5. During the conveying process, the silicon steel sheet is located in the C-shaped groove 707. As the silicon steel sheet is conveyed, the end of the silicon steel sheet will push the measuring block 703 to slide synchronously along the fixed length slide 702. The distance sensor 704 will detect the distance between the measuring block 703 and the distance sensor 704 in real time, and indirectly measure the length of the silicon steel sheet that is about to be cut. When the length reaches the specified distance, the distance sensor 704 will send an electrical signal to start the pressing and cutting operation, which can improve the cutting accuracy and further ensure the cutting quality. Rotating the contact roller 705 can reduce the frictional resistance and scratch risk during silicon steel sheet conveying, thereby improving product quality.

[0028] Below the length measuring block 703 is the electromagnetic block 706, which is L-shaped.

[0029] When the end of the silicon steel sheet comes into contact with the electromagnetic block 706, the two will be attracted together, which avoids the detection deviation caused by the premature slippage of the length measuring block 703 due to inertia caused by the fluctuation of the silicon steel sheet due to the conveying speed, thus ensuring the detection accuracy and further improving the fixed-length cutting accuracy. The distance between the lowest end of the electromagnetic block 706 and the highest end of the contact roller 705 is less than the minimum thickness of the processable silicon steel sheet, ensuring that the measuring block 703 is always located on the side of the silicon steel sheet away from the conveyor 2.

[0030] The unloading component 8 includes an unloading slide rail 801, an unloading slide rail slider 802, an unloading rod 803, a return spring 804, an unloading auxiliary slider 805, a wedge block 806, and a slot 807; Two feeding slide rails 801 are symmetrically installed on the cutting table 1. A feeding slide rail slider 802 is slidably mounted on the feeding slide rail 801. A feeding rod 803 is slidably mounted on the feeding slide rail slider 802. A feeding auxiliary slider 805 is slidably mounted on the feeding rod 803. A support base 701 is mounted on the feeding auxiliary slider 805. One side of the feeding auxiliary slider 805 is connected to the feeding rod 803 through a return spring 804. A wedge block 806 is installed on the cutting table 1. A slot 807 is opened on the wedge block 806. The slot 807 and the feeding rod 803 are located on the same vertical plane.

[0031] After cutting, the unloading slide block 802 moves downward along the unloading slide block 801. When the unloading auxiliary slide block 805 contacts the inclined surface of the wedge block 806, the inclined surface exerts a lateral thrust on the unloading auxiliary slide block 805, causing the unloading auxiliary slide block 805 to drive the support seat 701 to slide to both sides. At this time, the silicon steel sheet slides down, realizing autonomous downward movement and unloading. This improves processing efficiency while reducing the free fall distance of the silicon steel sheet, reducing damage. Secondly, it can simplify the unloading operation and improve efficiency.

[0032] The unloading component 8 also includes a vertical screw seat 808, a vertical screw 809, a horizontal screw seat 810, a horizontal screw 811, a drive bevel gear 812, a driven bevel gear 813, a smooth rod 814, a screw slider 815, a reset block 816, and a connecting rod 817. A vertical screw seat 808 and a horizontal screw seat 810 are installed on the cutting table 1. A vertical screw 809 is rotatably installed on the vertical screw seat 808 and is threadedly engaged with the support seat 701. A horizontal screw 811 is rotatably installed on the horizontal screw seat 810. A driving bevel gear 812 is provided at the end of the vertical screw 809, and a driven bevel gear 813 is installed at the end of the horizontal screw 811. The driving bevel gear 812 and the driven bevel gear 813 mesh. A smooth rod 814 is installed on the horizontal screw seat 810, and a screw slider 815 is slidably installed on the smooth rod 814. The screw slider 815 engages with the horizontal screw 811. A reset block 816 is slidably installed on the support seat 701, and a connecting rod 817 is installed on the reset block 816. The connecting rod 817 is slidably connected to the reset block 816.

[0033] After the material feeding is completed, the material feeding slide block 802 drives the support seat 701 to move upward and reset. At this time, the support seat 701 drives the vertical screw 809 to rotate. The vertical screw 809 drives the horizontal screw 811 to rotate through the threaded engagement of the driving bevel gear 812 and the driven bevel gear 813. The horizontal screw 811 is a reciprocating screw. The rotation of the horizontal screw 811 drives the screw slider 815 to move away from the vertical screw 809 first, and then move closer to the vertical screw 809. When the screw slider 815 moves, it will push the measuring block 703 to move closer to the cutting part 5 through the connecting rod 817 and the reset block 816. This ensures that the measuring block 703 can contact the end of the silicon steel sheet before reaching the cutting length when the silicon steel sheet is fed in the next time, ensuring the accuracy of fixed-length cutting and further ensuring the cutting quality. The drive bevel gear 812 is rotatably mounted on the cutting table 1, and the drive bevel gear 812 and the vertical screw 809 are unidirectionally driven. That is, the vertical screw 809 can drive the drive bevel gear 812 to rotate only when the support base 701 moves upward. The unidirectional drive can be achieved by a ratchet mechanism or the like.

[0034] The cutting table 1 is equipped with an auxiliary component 9, which includes an auxiliary slide rail 901, an auxiliary slide rail slider 902, a misalignment rod 903, and an electric suction cup 904. An auxiliary slide rail 901 is installed on the cutting table 1. An auxiliary slide rail slider 902 is provided on the auxiliary slide rail 901. An offset rod 903 is provided on the auxiliary slide rail slider 902. An electric suction cup 904 is installed at the end of the offset rod 903.

[0035] After the cutting is completed, the electric suction cup 904 adsorbs the silicon steel sheet below the cut sheet. Then, the auxiliary slide rail slider 902 moves the silicon steel sheet a specified distance away from the cut part 5, so that the cut end moves out of the bottom rod 603. Then, the electric suction cup 904 is reset and the unloading process is carried out. This can ensure that the silicon steel sheet is removed from the cutting station, realize unobstructed unloading, and avoid the end of the silicon steel sheet scratching the extrusion part 606, further ensuring the cutting quality.

[0036] The auxiliary component 9 also includes a detection slider 905 slidably mounted on the auxiliary slide rail 901. The detection slider 905 is connected to the auxiliary slide rail slider 902 through a detection spring 906. The misalignment rod 903 is mounted on the detection slider 905. A pressure sensor 907 is mounted on one end of the detection spring 906.

[0037] When the silicon steel sheet is pushed with assistance, the auxiliary slide rail slider 902 pushes the misalignment rod 903 through the detection spring 906. Under normal circumstances, the pressure sensor 907 displays a specified reading. When the reading of the pressure sensor 907 is greater than the specified reading, it indicates incomplete cutting or adhesion. The pressure sensor 907 sends an incomplete cutting electrical signal. When the reading of the pressure sensor 907 is less than the specified reading, it indicates that the electric suction cup 904 has failed to adsorb, and the electric suction cup 904 slips from the silicon steel sheet. The second sensor sends a failure electrical signal, which facilitates workers to carry out maintenance, shortens maintenance and inspection time, and improves production efficiency.

[0038] The extrusion component 606 is an inflatable airbag, which is externally connected to an inflatable component and a pressure sensor.

[0039] When the airbag is used for compression, after the contact sensor 605 contacts the silicon steel sheet, the contact sensor 605 sends an electrical signal, the compression rod 604 stops moving, and the inflation component supplies air to the airbag. The thickness of the silicon steel sheet is determined according to the different downward movement distance of the compression rod 604, and different amounts of gas are supplied to the airbag so that the pressure of the airbag on the silicon steel sheet is adapted to its thickness. The airbag and the silicon steel sheet are in flexible contact to avoid scratches caused by impurities or particles, or to avoid affecting the accuracy of the compression force, thus further ensuring the appropriate compression force.

[0040] The second embodiment differs from the first embodiment in that the extrusion part 606 is made of an elastic material.

[0041] The elastic material has a certain compression length corresponding to a certain pressure. When the contact sensor 605 contacts the silicon steel sheet, the clamping rod 604 continues to move downward according to the elastic coefficient of the elastic material, so that the elastic material applies a specified clamping force to the silicon steel sheet. The structure is simple and has a low failure rate.

[0042] Working principle of the invention: When silicon steel sheets need to be cut, the silicon steel sheets are conveyed forward by the conveyor 2. At this time, the end of the silicon steel sheet will push the length measuring block 703 to move synchronously. The distance sensor 704 detects the length of the silicon steel sheet to be cut in real time. When the specified length is reached, the distance sensor 704 sends an electrical signal to control the clamping slide rail 601 to stop running. The thickness of the silicon steel sheet is judged according to the downward movement distance of the clamping slider 602, and the clamping component 6 is controlled to apply the corresponding clamping force. Different clamping forces can be adaptively adjusted according to different silicon steel sheet thicknesses. This can avoid the silicon steel sheet from being indented, curling at the cut, and secondary burrs caused by unsuitable clamping force, effectively improving the cutting quality. After clamping, the cutting component 5 starts to cut the silicon steel sheet.

[0043] After the cutting is completed, the auxiliary component 9 uses the electric suction cup 904 to adsorb the bottom of the cut silicon steel sheet and move the cut silicon steel sheet forward a certain distance. This ensures that the silicon steel sheet is removed from the cutting station, achieving unobstructed material unloading while avoiding scratching the extrusion part 606 at the end of the silicon steel sheet, further ensuring the cutting quality.

[0044] When the material is unloaded, the support base 701 moves down and contacts the wedge block 806. Due to the lateral thrust of the wedge block 806, the silicon steel sheet falls off, thus completing the automatic unloading.

[0045] After the material is unloaded, the support base 701 moves upward. At this time, the upward movement of the support base 701 will drive the reset block 816 to push the length measuring block 703 to reset, so as to facilitate the length setting operation before the next cutting.

[0046] The unloading component 8 achieves self-unloading by moving downwards, reducing the height from which the silicon steel sheet falls freely during unloading and reducing the impact force of falling. At the same time, the reset after moving downwards drives the length measuring block 703 to reset, improving detection accuracy and further ensuring cutting quality.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
