Description

Technical Field

[0001] This invention belongs to the field of transformer manufacturing technology, and specifically provides a segmented cutting machine for transformer insulation materials. Background Technology

[0002] Transformers are core equipment in power systems, and the reliability of their insulation system is directly related to the service life of the transformer. In the transformer manufacturing process, insulation materials need to be precisely cut and processed into sheets that meet the size requirements for use in the key insulation parts of the transformer.

[0003] Currently, the cutting and processing of transformer insulation materials mainly involves the following types of processes: Mechanical die-cutting or punching processes, which use molds to cut insulating paperboard, have the following drawbacks: the cutting tool is in direct contact with the material, which easily produces burrs on the cut edges, thus reducing the reliability of insulation performance; the cutting tool wears out quickly during continuous cutting, which can easily cause dimensional deviations and make it impossible to guarantee the consistency and stability of mass production; frequent replacement and resharpening of cutting tools increases production costs and equipment downtime, ultimately reducing production efficiency. Laser cutting technology can solve the problem of burrs on the cutting edge, but it has the disadvantage of high equipment purchase cost, and the smoke generated during the cutting process requires additional purification equipment, resulting in high overall production cost and process complexity. The online automatic cutting process for the insulation paper between the layers of transformer high-voltage line sheaths is an online cutting process that is only suitable for the end cutting process of coil winding and cannot be adapted to the segmented cutting requirements of offline insulation paperboard.

[0004] In addition to the defects in the process itself, existing cutting equipment also generally suffers from insufficient paper feeding and guiding accuracy, which makes the paper tape easy to deviate or run off course during the paper tape conveying process, ultimately resulting in inaccurate cutting position. Furthermore, the paper tape conveying may stop at the moment of cutting, and subsequent continuous conveying may cause paper tape to accumulate, which in turn has an adverse effect on cutting accuracy and production stability. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a segmented cutting machine for transformer insulation materials, including a machine body, a coil assembly shaft, a pinching guide mechanism, a lifting platform, a precision guide mechanism, and a shearing mechanism. The coil assembly shaft is rotatably mounted on the side wall of the machine body and is driven by a motor. The coil assembly shaft is used to assemble paper tape bundles. The pinching guide mechanism and the lifting platform are both mounted on the side wall of the machine body by linear motors. The precision guide mechanism is mounted on the machine body by a first lifting arm. The fixed end of the shearing mechanism is mounted on the lifting platform, and the movable end of the shearing mechanism is mounted on the machine body by a second lifting arm. The coil assembly shaft is the feeding end, the shearing mechanism is the discharging end, and the kneading guide mechanism and the precision guide mechanism are distributed sequentially from the feeding end to the discharging end on the paper tape conveying track.

[0006] Furthermore, the precision guiding mechanism includes a first assembly frame, a drive assembly, a guide plate, a vertical limiting plate, and a rotation amplitude limiting groove. The first assembly frame is mounted on the movable end of the first lifting arm via an electric push rod. The first assembly frame is an inverted L-shaped corner frame. The drive assembly is fixedly mounted on the side wall of the first assembly frame. The guide plate is mounted on the output end of the drive assembly. The side wall of the guide plate extends upward to form a vertical limiting plate. The feed end and discharge end of the guide plate are respectively chamfered. The guide plate is provided with an inlet guide wheel at the inlet end; An arc-shaped rotation amplitude limiting groove is provided on the contact surface between the first assembly frame and the guide plate. A limiting pin is provided on the side wall of the guide plate, and the limiting pin is inserted into the rotation amplitude limiting groove. The rotation amplitude limiting groove is coaxial with the output shaft of the drive assembly.

[0007] Furthermore, the shearing mechanism includes a hydraulic lifting seat, a first flexible positioning column, a cutting blade, a second flexible positioning column, a rigid positioning column, and a cutting groove. The hydraulic lifting seat is fixedly installed on the movable end of the second lifting arm. The first flexible positioning column, the cutting blade, and the second flexible positioning column are all vertically installed on the lower end face of the hydraulic lifting seat, and the first and second flexible positioning columns are symmetrically arranged on both sides of the cutting blade. The two rigid positioning columns and the cutting groove are fixedly installed on the lifting platform, and the two rigid positioning columns are respectively located on both sides of the cutting groove. The positions of the two rigid positioning columns correspond to the positions of the first and second flexible positioning columns, and the positions of the cutting groove and the cutting blade correspond to each other.

[0008] Furthermore, the height difference between the lower end faces of the first flexible positioning post and the second flexible positioning post is h.

[0009] Furthermore, a compensation pin is fitted between the rigid positioning post and the cutting groove.

[0010] Furthermore, the compensation pin includes a U-shaped clamp, a positioning seat, a trapezoidal wedge, and a double-layer screw. A trapezoidal wedge groove is provided in the gap in the middle of the U-shaped clamp. The trapezoidal wedge is inserted into the wedge groove. The positioning seat is fastened to the bottom of the U-shaped clamp. The double-layer screw passes through the positioning seat from bottom to top and is screwed to the U-shaped clamp. The end of the double-layer screw passes through the bottom of the U-shaped clamp and extends into the wedge groove. The top of the double-layer screw abuts against the bottom surface of the trapezoidal wedge.

[0011] Furthermore, a segmented cutting machine for transformer insulation materials also includes a pause compensation mechanism, on which multiple guide rollers are rotatably mounted, and a linear compensation component is mounted inside the pause compensation mechanism, with a tension roller mounted on the sliding part of the linear compensation component.

[0012] Furthermore, the linear compensation assembly includes a base, a connecting frame, a lead screw, a linear bearing, a sliding groove, a sliding frame, and a shaft frame. The lead screw and linear bearing are arranged parallel to each other inside the pause compensation mechanism. The base is fastened to the movable end of the lead screw and linear bearing. The sliding groove is fixedly connected to the base through the connecting frame. The sliding frame is slidably assembled in the sliding groove, and a pneumatic spring is assembled at the bottom of the sliding frame. The two ends of the pneumatic spring are fixedly connected to the two end faces of the sliding groove, respectively. The sliding frame can slide along the sliding groove and, under the restriction of the pneumatic spring, can slowly return to its original position after displacement. The shaft frame is fixedly installed on the sliding frame, and the tension roller is rotatably installed on the shaft frame.

[0013] Furthermore, the linear compensation assembly is internally equipped with a positioning sensor, which is located on the same mounting surface as the end of the lead screw and linear bearing. The base is equipped with a baffle plate, the position of which matches the positioning sensor. Both the lead screw and the linear bearing are equipped with encoder motors at their movable ends. The screw sleeve of the lead screw can rotate under the control of the corresponding encoder motor, driving the movable end of the lead screw to move along the screw thread. The movable end of the linear bearing has a built-in clamping mechanism, which achieves locking positioning under the control of the corresponding encoder motor. A pressure sensor is installed on the tensioning roller.

[0014] Furthermore, a bridging plate positioning groove is provided at the discharge end of the guide plate, and a bridging plate is assembled on the fixed end of the shearing mechanism, with the bridging plate extending and overlapping at the bridging plate positioning groove.

[0015] The beneficial effects of using this invention are: This invention uses a precision guiding mechanism to accurately guide the paper tape. The precision guiding mechanism has three degrees of freedom and can dynamically adjust the position and angle of the guide plate according to the actual conveying path of the paper tape. This effectively prevents the paper tape from deviating or running off course during the conveying process, ensuring that the paper tape enters the cutting mechanism in the correct posture, thereby improving the accuracy and consistency of the cutting position.

[0016] The shearing mechanism employs a design where a first flexible positioning post and a second flexible positioning post cooperate with a rigid positioning post. During the shearing action, the first flexible positioning post first contacts the paper tape and engages with the rigid positioning post below to lock one end of the paper tape. Subsequently, the second flexible positioning post contacts the paper tape and locks the other end of the paper tape. Finally, the cutting blade completes the cutting operation. This timing control method of positioning before cutting ensures that the paper tape is reliably fixed at the moment of cutting, avoiding cutting deviations caused by paper tape displacement. At the same time, the elastic design of the flexible positioning post can buffer the cutting impact force, protect the edges of the paper tape from damage, and ensure a smooth, burr-free cut edge.

[0017] The wedge-shaped self-locking structure of the compensation pin, combined with the wedge groove of the trapezoidal wedge block and the U-shaped clamping plate, and the precise adjustment of the double-layer screws, can fully fill the gap between the rigid positioning column and the cutting groove, ensuring the stable and reliable relative position of the rigid positioning column and the cutting groove. This effectively eliminates the accumulation of gaps caused by vibration or wear during long-term use, extends the equipment maintenance cycle, and ensures the stability of cutting accuracy during long-term operation.

[0018] The problem of paper tape stagnation during cutting is solved by a pause compensation mechanism: When the shearing mechanism performs the cutting action, the pressure sensor detects a decrease in paper tape tension. The encoder motor controls the clamping mechanism to unlock, and the lead screw drives the tension roller to step forward, synchronously dragging the paper tape back a short distance. This compensates for the end-of-line paper tape conveying stagnation caused by the cutting action, preventing paper tape from accumulating or wrinkling in the cutting area. This compensation mechanism responds quickly and the compensation distance is precisely controllable, ensuring the smoothness of paper tape conveying and the consistency of the cutting rhythm during continuous production.

[0019] The overall structure is compact, and the functional modules are rationally laid out. From the coil assembly shaft to the shearing mechanism, a complete automated paper feeding-guiding-cutting production line is formed. With the help of the kneading guide mechanism, the lifting platform and other multi-degree-of-freedom adjustment mechanisms, it can adapt to transformer insulation paper tapes of different widths, thicknesses and materials. It has good versatility and flexibility and is suitable for the needs of large-scale, high-precision segmented cutting production of transformer insulation materials. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] Reference Figure 1 and Figure 2 A segmented cutting machine for transformer insulation materials includes a main body 1, a coil assembly shaft 2, a pinching guide mechanism 3, a lifting platform 4, a precision guide mechanism 6, and a shearing mechanism 8. The main body 1 has built-in necessary components such as a motor, an electrical control module, a hydraulic control module, and an interactive module. The coil assembly shaft 2 is rotatably mounted on the side wall of the main body 1 and is driven by a motor. The coil assembly shaft 2 is used to assemble paper tape bundles. The pinching guide mechanism 3 and the lifting platform 4 are both mounted on the side wall of the main body 1 by linear motors. The precision guide mechanism 6 is mounted on the main body 1 by a first lifting arm 5. The fixed end of the shearing mechanism 8 is mounted on the lifting platform 4, and the movable end of the shearing mechanism 8 is mounted on the main body 1 by a second lifting arm 7. The coil assembly shaft 2 is the feeding end, the shearing mechanism 8 is the discharging end, and the kneading guide mechanism 3 and the precision guide mechanism 6 are distributed sequentially from the feeding end to the discharging end on the paper tape conveying track. The kneading guide mechanism 3 and the lifting platform 4 have vertical degrees of freedom, while the precision guide mechanism 6 has three-dimensional degrees of freedom.

[0023] Reference Figure 3 The precision guiding mechanism 6 includes a first assembly frame 601, a drive assembly 602, a guide plate 603, a vertical limiting plate 604, and a rotation amplitude limiting groove 607. The first assembly frame 601 is mounted on the movable end of the first lifting arm 5 via an electric push rod. The first assembly frame 601 is an inverted L-shaped corner frame. The drive assembly 602 is fixedly mounted on the side wall of the first assembly frame 601. The guide plate 603 is mounted on the output end of the drive assembly 602. The side wall of the guide plate 603 extends upward to form the vertical limiting plate 604. The feed end and discharge end of the guide plate 603 are respectively chamfered. An infeed guide wheel 605 is provided at the feed end of the guide plate 603; An arc-shaped rotation amplitude limiting groove 607 is provided on the contact surface between the first assembly frame 601 and the guide plate 603. A limiting pin is provided on the side wall of the guide plate 603, and the limiting pin is inserted into the rotation amplitude limiting groove 607. The rotation amplitude limiting groove 607 is coaxial with the output shaft of the drive assembly 602.

[0024] Reference Figure 4 and Figure 5 The shearing mechanism 8 includes a hydraulic lifting seat 801, a first flexible positioning column 802, a cutting blade 803, a second flexible positioning column 804, a rigid positioning column 805, and a cutting groove 806. The hydraulic lifting seat 801 is fixedly installed on the movable end of the second lifting arm 7. The first flexible positioning column 802, the cutting blade 803, and the second flexible positioning column 804 are all vertically installed on the lower end face of the hydraulic lifting seat 801, and the first flexible positioning column 802 and the second flexible positioning column 804 are symmetrically arranged on both sides of the cutting blade 803. The two rigid positioning columns 805 and the cutting groove 806 are fixedly installed on the lifting platform 4, and the two rigid positioning columns 805 are respectively located on both sides of the cutting groove 806. The positions of the two rigid positioning columns 805 correspond to the positions of the first flexible positioning column 802 and the second flexible positioning column 804, and the positions of the cutting groove 806 and the cutting blade 803 correspond to each other. Reference Figure 10 Preferably, the height difference between the lower end faces of the first flexible positioning post 802 and the second flexible positioning post 804 is h; When performing the cutting action, the first flexible positioning post 802 first contacts the paper tape and cooperates with the lower rigid positioning post 805 to lock one end of the paper tape. Then, the second flexible positioning post 804 contacts the paper tape and cooperates with the lower rigid positioning post 805 to lock the other end of the paper tape. Finally, the cutting blade 803 contacts the paper tape to complete the paper tape cutting operation.

[0025] In addition, during the process of the cutting blade 803 fully cutting into the cutting groove 806, the blade will rub against the side wall of the cutting groove 806, which will have a sharpening effect.

[0026] The flexible positioning column consists of a rectangular positioning seat, a U-shaped movable side, an elastic connector, and a guide column. When the U-shaped movable side receives pressure greater than the bearing threshold of the elastic connector, the U-shaped movable side compresses the elastic connector and slides along the guide column.

[0027] A compensating pin 807 is assembled between the rigid positioning post 805 and the cutting groove 806.

[0028] Reference Figure 6 The compensation pin 807 includes a U-shaped clamp 8071, a positioning seat 8072, a trapezoidal wedge 8073, and a double-layer screw 8074. A trapezoidal wedge groove is provided in the gap in the middle of the U-shaped clamp 8071. The trapezoidal wedge 8073 is inserted into the wedge groove. The positioning seat 8072 is fastened to the bottom of the U-shaped clamp 8071. The double-layer screw 8074 passes through the positioning seat 8072 from bottom to top and is screwed into the U-shaped clamp 8071. The end of the double-layer screw 8074 passes through the bottom of the U-shaped clamp 8071 and extends into the wedge groove. The top of the double-layer screw 8074 abuts against the bottom surface of the trapezoidal wedge 8073. The specific structure of the double-layer screw 8074 includes an outer screw and an inner screw. The outer screw is an internal hexagonal screw with a cavity coaxially arranged inside, and an internal thread is provided on the inner wall of the cavity. The inner screw is screwed into the internal thread, and the top of the inner screw extends to the outside of the outer screw. When the outer screw is screwed into the limit position, by continuing to screw the inner screw, a further thrust can be applied to the trapezoidal wedge 8073. The trapezoidal wedge 8073 moves upward and presses against the inclined inner wall of the wedge groove, driving the two plates of the U-shaped clamp 8071 to open in opposite directions. The two plates apply thrust to the rigid positioning post 805 and the cutting groove 806 respectively, fully filling the gap between the rigid positioning post 805 and the cutting groove 806, ensuring the stability of the two rigid positioning posts 805 and the cutting groove 806.

[0029] Reference Figures 7-9 A segmented cutting machine for transformer insulation materials also includes a pause compensation mechanism 9, on which multiple guide rollers 901 are rotatably mounted, and a linear compensation component 902 is mounted inside the pause compensation mechanism 9. A tension roller 903 is mounted on the sliding part of the linear compensation component 902. The tension roller 903 can move linearly and adaptively, dragging the paper tape that passes through it to achieve a tensioning effect. It is used to synchronously drag the paper tape back a small section when performing the shearing action to compensate for the paper tape retention caused by the end of the paper tape feeding stopping at the moment of the shearing action.

[0030] Specifically, the linear compensation assembly 902 includes a base 9021, a connecting frame 9022, a lead screw 9023, a linear bearing 9024, a sliding groove 9025, a sliding frame 9026, and a shaft frame 9028. The lead screw 9023 and the linear bearing 9024 are arranged in parallel inside the pause compensation mechanism 9. The base 9021 is fastened to the movable ends of the lead screw 9023 and the linear bearing 9024. The sliding groove 9025 is fixedly connected to the base 9021 through the connecting frame 9022. The sliding frame 9026 is slidably assembled in the sliding groove 9025, and a pneumatic spring 9027 is assembled at the bottom of the sliding frame 9026. The two ends of the pneumatic spring 9027 are fixedly connected to the two end faces of the sliding groove 9025 respectively. The sliding frame 9026 can slide along the sliding groove 9025, and under the restriction of the pneumatic spring 9027, it can slowly return to its original position after displacement. The shaft frame 9028 is fixedly installed on the sliding frame 9026, and the tension roller 903 is rotatably installed on the shaft frame 9028.

[0031] The linear compensation assembly 902 is equipped with a position sensor 904. The position sensor 904 is located on the same mounting surface as the end of the lead screw 9023 and the linear bearing 9024. The base 9021 is equipped with a baffle plate, and the position of the baffle plate matches that of the position sensor 904. Both the lead screw 9023 and the linear bearing 9024 are equipped with encoder motors 9029 at their moving ends. The screw sleeve of the lead screw 9023 can rotate under the control of the corresponding encoder motor 9029, driving the moving end of the lead screw 9023 to move along the screw. The moving end of the linear bearing 9024 has a built-in clamping mechanism, which achieves locking positioning under the control of the corresponding encoder motor 9029. A pressure sensor is installed on the tension roller 903; When the pressure drops, it means that the shearing mechanism 8 is performing a shearing action. The command is inserted, and at this moment, the encoder motor 9029 is controlled to release the locking state of the clamping mechanism. The lead screw 9023 drives the tension roller 903 to step. The stepping distance is set according to the paper belt conveying speed and the execution time of the shearing action, and usually does not exceed 1.5 mm. Taking a 300 mm lead screw as an example, the distance formed by the lead screw 9023 in a single operation can achieve 200 compensations. When the positioning sensor 904 reports that the tension roller 903 has reached its limit position, the encoder motor 9029 drives the lead screw 9023 to reverse, thereby resetting the tension roller 903.

[0032] A bridging plate positioning groove 606 is provided at the discharge end of the guide plate 603, and a bridging plate 10 is assembled on the fixed end of the shearing mechanism 8. The bridging plate 10 extends and overlaps at the bridging plate positioning groove 606.

[0033] Reference Figure 11The surface of the lifting platform 4 is provided with an assembly groove 401. The bottom of the rigid positioning column 805 and the cutting groove 806 are bolted with I-beam clamps 808, and the assembly groove 401 is reinforced by the I-beam clamps 808 to achieve the fixing effect of the rigid positioning column 805 and the cutting groove 806. Similarly, the positioning seat 8072 and the U-shaped clamp 8071 are adjusted and fixed by double-layer screws 8074.

[0034] In addition, this equipment also supports the bonding of composite paper tapes, see reference. Figure 9 The three coil assembly shafts 2 can be selectively configured with paper tapes of different functions (such as a combination of tensile paper tape, double-sided adhesive paper tape and aramid paper tape). The three types of paper tapes converge at the pinching guide mechanism 3, and after being pressed and bonded by the pinching guide mechanism 3, they are output to the subsequent process for cutting. Users can also enable this part of the function separately according to their needs (that is, the coil assembly shafts 2 and the pinching guide mechanism 3 and other functional structures are all powered by separate control).

[0035] The above content is only a preferred embodiment of the present invention. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the concept of the present invention. As long as these changes do not depart from the concept of the present invention, they all fall within the protection scope of the present invention.
