Description

Technical Field

[0001] This invention relates to the field of transformer insulation board processing technology, specifically to a shearing device and shearing method for processing transformer insulation boards. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components consist of a primary coil, a secondary coil, and an iron core. The materials used in transformer installation include core material, insulation material, and impregnating material. Among these, the insulation board plays a crucial role. First, it provides critical electrical insulation, effectively isolating the high and low voltage windings and the windings from the iron core, preventing short circuits and discharge accidents, and ensuring equipment safety. Second, it forms oil channels and other structures, ensuring smooth circulation of transformer oil and facilitating heat dissipation. Simultaneously, the insulation board acts as a support, bearing the mechanical and electromagnetic forces of the coils, ensuring the stability of the windings under conditions such as short circuits.

[0003] During the processing of insulation boards, shearing equipment is needed to cut them into uniformly sized sheet materials to facilitate subsequent assembly and stacking, meeting the high-precision process requirements of transformer manufacturing. Currently, after being cut into individual sheets, the complete sheet material often falls directly into the discharge box placed at the discharge port. However, there is a significant height difference between the discharge box and the discharge port, and the falling sheet material generates considerable impact, easily damaging the material and affecting subsequent assembly and use. Summary of the Invention

[0004] The purpose of this invention is to provide a shearing device and shearing method for processing transformer insulation boards. The processing integrates cutting, dust removal, and unloading, and has the advantages of high efficiency and continuity, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a shearing device for processing transformer insulation boards, comprising a conveyor table and a U-shaped plate connected to one end of the conveyor table. The conveyor table is connected to a driving mechanism for driving the board forward. The driving mechanism includes a motor, two rotating wheels, a transmission belt, and a cross plate. The two rotating wheels are connected by the transmission belt. The motor drives the rotating wheels to rotate. The cross plate is connected to the transmission belt. A support plate is connected to the bottom of the conveyor table. The support plate is connected to a pushing mechanism for moving the board. The U-shaped plate is connected to a shearing mechanism for shearing the board and a dust collection hood for dust collection. The shearing mechanism includes a hydraulic cylinder and a shearing blade. The hydraulic cylinder drives the shearing blade to rise and fall. A transmission mechanism is connected between the shearing blade and the dust collection hood for driving them to move closer or further apart.

[0006] Preferably, the drive mechanism further includes a connecting frame, multiple positioning bolts, and multiple L-shaped baffles. The connecting frame is used to guide the two rotating wheels, the multiple L-shaped baffles are connected to the front end of the horizontal plate, and the positioning bolts are threaded to the L-shaped baffles.

[0007] Preferably, the connecting frame and the motor are connected to the bottom of the conveyor table, two rotating wheels are rotatably connected to the connecting frame, and the power output end of the motor is connected to the rotating wheels.

[0008] Preferably, the conveyor table is provided with a rectangular hole and guide rails connected to both sides, and the horizontal plate is slidably connected to the rectangular hole and the two guide rails.

[0009] Preferably, the pushing mechanism includes a rotating disk, an elongated plate, multiple chutes, a push plate, a transmission chain, two sprockets, two guide frames, a rotating shaft, a first conical tooth, and a second conical tooth. The guide frames guide the rotating shaft, and the two guide frames are respectively connected to the bottom of the conveyor table and the bottom of the support plate. The rotating disk is connected to the sprocket located above it via a shaft, and the two sprockets are connected to each other via a transmission chain. The two ends of the rotating shaft are respectively connected to the sprocket and the first conical tooth. The first conical tooth is used for the second conical tooth and the rotating disk to rotate synchronously. The two ends of the elongated plate are respectively connected to the rotating disk and the push plate shaft, and the chutes guide the push plate.

[0010] Preferably, the first conical tooth and the second conical tooth are meshed together, the second conical tooth is axially connected to the rotating disk, and the shaft is rotatably connected to the support plate.

[0011] Preferably, the push plate is slidably connected to a plurality of sliding grooves, which are disposed on the top of the support plate.

[0012] Preferably, the transmission mechanism includes two upper toothed plates, two transmission teeth, two lower toothed plates, two guide blocks, two guide frames, and two guide holes. The ends of the upper toothed plates are connected to the shearing blades and are slidably connected to the U-shaped plate. The transmission teeth are rotatably connected to the U-shaped plate and are respectively meshed with the upper toothed plates and the lower toothed plates. The guide frames are connected to the front end of the U-shaped plate, the guide holes are provided in the guide frames, and the guide blocks are slidably connected to the guide holes. The top of the lower toothed plates is connected to the guide blocks, and the bottom of the lower toothed plates is connected to the dust collection hood.

[0013] Preferably, the top of the dust hood has evenly distributed dust suction holes, and the bottom of the dust hood is connected to a dust suction pipe. The dust suction pipe is connected to a valve, and the lower toothed plate is connected to a pressing plate. The pressing plate is used to control the opening and closing of the valve.

[0014] A shearing method for a shearing device used in processing transformer insulation boards includes the following steps:

[0015] Step 1: The hydraulic cylinder drives the shearing blade to descend, which in turn drives the two upper toothed plates to descend synchronously. In conjunction with the use of two transmission teeth, the two lower toothed plates move upward synchronously. The lower toothed plates drive the dust collection hood to move upward. At the same time, the pressing plate separates from the valve, putting the dust collection pipe into the conducting state, that is, the dust collection hood starts to suck air. When the dust collection hood is in contact with the surface of the conveyor table, the shearing blade has completed the cutting operation of the sheet. The sheet falls to the top of the dust collection hood. The negative pressure inside the dust collection hood can fix the sheet and at the same time absorb the cutting debris to avoid polluting the surrounding environment.

[0016] Step 2: The hydraulic cylinder then drives the shearing blade to move upward. Through the coordinated use of the upper toothed plate, transmission tooth, and lower toothed plate, the dust hood moves downward to the initial position, simultaneously driving the sheet material down. The pressing plate presses against the valve, at which point the valve closes, stopping the dust hood from pumping air and loosening the sheet material.

[0017] Step 3: The drive mechanism moves the small end of the sheet material on the conveyor table forward to prepare for subsequent cutting. At the same time, through the combined use of two sprockets, a transmission chain, a rotating shaft, and conical teeth one and two, the rotating disk rotates one revolution. In conjunction with the use of the elongated plate, the push plate can be driven to move back and forth. The push plate hits the sheet material on the top of the dust collection hood, moving the sheet material to the discharge plate to achieve safe unloading and ensure the integrity of the sheet material.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention is equipped with a driving mechanism, a pushing mechanism, a dust collection hood, and a transmission mechanism. The hydraulic cylinder drives the shearing blade to descend, and the shearing blade synchronously drives the two upper toothed plates to descend. With the use of two transmission teeth, the two lower toothed plates and the dust collection hood move upward, so that the dust collection hood fits against the end of the conveyor table. Then the shearing blade cuts the sheet material, and the sheet material falls to the top of the dust collection hood. At this time, the valve is in the open state. The dust collection hood can not only achieve the adsorption and fixation of the sheet material, but also achieve the purpose of dust collection, reducing pollution to the surrounding environment. Furthermore, the hydraulic cylinder drives the shearing blade upward, causing the dust hood and sheet material to descend to their initial positions. Then, the drive mechanism moves the sheet material on the conveyor table forward at its small end to prepare for subsequent cutting. Through the coordinated use of two sprockets, a transmission chain, a rotating shaft, and conical teeth one and two, the rotating disk rotates one revolution. In conjunction with the use of the elongated plate, the push plate can be driven to move back and forth. The push plate impacts the sheet material on top of the dust hood, moving the sheet material onto the discharge plate to achieve safe unloading and ensure the integrity of the sheet material. The entire process integrates cutting, dust removal, and unloading into one efficient and continuous process. Attached Figure Description

[0027] 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.

[0028] Please see Figures 1 to 7This invention provides a shearing device for processing transformer insulation boards, including a conveyor table 1 and a U-shaped plate 7 connected to one end of the conveyor table 1. The conveyor table 1 is connected to a driving mechanism for driving the board forward. The driving mechanism includes a motor 28, two rotating wheels 27, a transmission belt 26, and a horizontal plate 2. The two rotating wheels 27 are connected by the transmission belt 26. The motor 28 drives the rotating wheels 27 to rotate. The horizontal plate 2 is connected to the transmission belt 26. A support plate 18 is connected to the bottom of the conveyor table 1. The support plate 18 is connected to a pushing mechanism for moving the board. The U-shaped plate 7 is connected to a shearing mechanism for shearing the board and a dust collection hood 10 for dust collection. The shearing mechanism includes a hydraulic cylinder 8 and a shearing blade 9. The hydraulic cylinder 8 drives the shearing blade 9 to rise and fall. A transmission mechanism is connected between the shearing blade 9 and the dust collection hood 10 for driving them to move closer or further apart.

[0029] The U-shaped plate 7 is connected to a guide plate, and the shearing blade 9 passes through the guide plate. The two are slidably connected, which improves the stability of the shearing blade 9 in raising and lowering, and can accurately shear the plate, thus improving the shearing accuracy.

[0030] The plate on the conveyor table 1 is moved forward a certain distance by a drive mechanism, so that one end of the plate protrudes from the end face of the conveyor table 1, and the end face is... Figure 1 In section a, the protruding part of the sheet material is the shearing section. Hydraulic cylinder 8 drives the shearing blade 9 to descend, simultaneously causing the two upper toothed plates 12 to descend as well. The upper toothed plates 12 drive the transmission gear 13 to rotate, which in turn drives the lower toothed plate 14 to move upward, thus raising the dust collection hood 10. When the dust collection hood 10 is in contact with section a, the shearing blade 9 has completed shearing the sheet material, and the sheet material falls to the top of the dust collection hood 10. Furthermore, because the pressing plate 24 is separated from the valve 19, the valve 19 is in the open state, allowing the suction pipe 25 to suction the dust collection hood 10. This not only adsorbs and fixes the sheet material for easy unloading, but also adsorbs the debris generated during shearing, preventing pollution of the surrounding environment.

[0031] Furthermore, the hydraulic cylinder 8 drives the shearing blade 9 to move upward to the initial position. Through the coordinated use of the upper toothed plate 12, the transmission gear 13, and the lower toothed plate 14, the dust suction hood 10 is lowered to the initial position, simultaneously driving the sheet material downward and effectively reducing the material discharge height. At the same time, the pressing plate 24 presses against the valve 19, and the valve 19 is in the closed state, that is, the dust suction pipe 25 is blocked, so that the air pressure inside and outside the dust suction hood 10 is balanced, thereby loosening the top sheet material and facilitating subsequent unloading.

[0032] The drive mechanism also includes a connecting frame, multiple positioning bolts 3, and multiple L-shaped baffles 4. The connecting frame is used to guide the two rotating wheels 27, the multiple L-shaped baffles 4 are connected to the front end of the horizontal plate 2, and the positioning bolts 3 are threaded to the L-shaped baffles 4.

[0033] The sheet material is placed on top of the conveyor table 1, with its end face abutting against the inside of the L-shaped baffle 4, thus initially limiting the sheet material's position. Then, the positioning bolts 3 are tightened, pressing their bottoms against the sheet material, thereby improving the stability of the sheet material's forward movement and facilitating subsequent shearing operations.

[0034] The connecting frame and motor 28 are connected to the bottom of the conveyor table 1. Two rotating wheels 27 are rotatably connected to the connecting frame. The power output end of the motor 28 is connected to the rotating wheels 27.

[0035] The conveyor table 1 is provided with a rectangular hole 5 and guide rails 6 connected to both sides. The horizontal plate 2 is slidably connected to the rectangular hole 5 and the two guide rails 6, which improves the stability of the reciprocating movement of the horizontal plate 2 and plays a good guiding role.

[0036] The driving mechanism includes a rotating disk 20, an elongated plate 21, multiple chutes 22, a push plate 23, a transmission chain 29, two sprockets 30, two guide frames 31, a rotating shaft 32, a first conical tooth 33, and a second conical tooth 34. The guide frame 31 guides the rotating shaft 32. The two guide frames 31 are respectively connected to the bottom of the conveyor table 1 and the bottom of the support plate 18. The rotating wheel 27 is connected to the sprocket 30 located above it via a shaft. The two sprockets 30 are connected by a chain drive 29. The two ends of the rotating shaft 32 are respectively connected to the sprocket 30 and the first conical tooth 33. The first conical tooth 33 is used for the second conical tooth 34 and the rotating disk 20 to rotate synchronously. The two ends of the elongated plate 21 are respectively connected to the rotating disk 20 and the push plate 23 shaft. The chutes 22 guide the push plate 23.

[0037] When the sheet material on the dust hood 10 needs to be unloaded, the motor 28 drives the rotating wheel 27 closer to the inside to rotate. The two rotating wheels 27 rotate via a transmission belt 26, which moves the horizontal plate 2 forward by a certain displacement, causing its end to protrude (a) in preparation for shearing. Simultaneously, the rotating wheel 27 drives the corresponding sprocket 30 to rotate. The sprocket 30, through the transmission chain 29, drives the lower sprocket 30 to rotate, achieving synchronous rotation of the rotating shaft 32 and the first conical tooth 33. The first conical tooth 33 drives the second conical tooth 34 and the rotating disk 20 to rotate. The rotation direction of the rotating disk 20 is... Figure 4 The middle arrow points to the direction, and in conjunction with the use of the elongated plate 21, the push plate 23 moves back and forth quickly. The push plate 23 pushes the sheet material towards the discharge plate 11, allowing it to slide smoothly down from the discharge plate 11. This avoids the impact force caused by the sheet material falling directly from a height, ensuring the integrity of the sheet material and achieving a good unloading purpose.

[0038] Figure 4 The push plate 23 is in the initial position. After the rotary table 20 rotates one revolution, the push plate 23 moves forward, then backward, and then moves forward again to the initial position. One revolution of the rotary table 20 corresponds to the displacement of the plate material at the top of the conveyor table 1, which is the size of the plate material shearing.

[0039] The first conical tooth 33 and the second conical tooth 34 mesh with each other, resulting in high transmission efficiency and ensuring a constant instantaneous transmission ratio. The second conical tooth 34 is axially connected to the rotating disk 20, and this shaft is rotatably connected to the support plate 18, making the rotating disk 20 rotate stably.

[0040] The push plate 23 is slidably connected to multiple slide grooves 22. The slide grooves 22 are set on the top of the support plate 18. The slide grooves 22 guide the push plate 23 and improve the stability of the push plate 23's reciprocating movement.

[0041] The transmission mechanism includes two upper toothed plates 12, two transmission teeth 13, two lower toothed plates 14, two guide blocks 15, two guide frames 16, and two guide holes 17. The end of the upper toothed plate 12 is connected to the shearing blade 9, and the upper toothed plate 12 is slidably connected to the U-shaped plate 7 to improve the stability of the reciprocating movement of the upper toothed plate 12. The transmission teeth 13 are rotatably connected to the U-shaped plate 7 and are meshed with the upper toothed plates 12 and the lower toothed plates 14 respectively. The guide frames 16 are connected to the front end of the U-shaped plate 7, and the guide holes 17 are set in the guide frames 16. The guide blocks 15 are slidably connected to the guide holes 17. The top of the lower toothed plate 14 is connected to the guide blocks 15, and the bottom of the lower toothed plate 14 is connected to the dust collection hood 10.

[0042] The guide block 15 guides the lower toothed plate 14, ensuring stable reciprocating movement of the lower toothed plate 14 and guaranteeing effective transmission between the lower toothed plate 14, the upper toothed plate 12, and the transmission gear 13, thus preventing transmission jamming. When the dust hood 10 descends to its initial position, the guide block 15 is connected to the bottom of the guide hole 17, meaning the two guide frames 16 can firmly support the dust hood 10. When the cutting device is not in use, the hydraulic cylinder 8 is in a stopped state, and the weight of the dust hood 10 itself prevents the shearing blade 9 from sliding down.

[0043] The vacuum duct 25 includes a fixed duct and a corrugated duct. One end of the corrugated duct is connected to the bottom of the vacuum hood 10, and the other end is connected to the fixed duct. One end of the fixed duct is connected to a valve 19, which is fixed to a bracket at the bottom of the conveyor table 1. The end of the valve 19 is connected to a vacuum unit, which is existing technology. When the vacuum hood 10 is raised or lowered, the corrugated duct extends or retracts.

[0044] The top of the dust hood 10 has evenly distributed dust suction holes, and the bottom of the dust hood 10 is connected to a dust suction pipe 25. The dust suction pipe 25 is connected to a valve 19, and the lower toothed plate 14 is connected to a pressing plate 24. The pressing plate 24 is used to control the opening and closing of the valve 19.

[0045] Valve 19 is a spring-return valve, comprising a valve body, a valve core (or diaphragm), a return spring, and an operating button. In its natural state, the preload of the spring pushes the valve core to a specific position, keeping the valve in a fixed state of normally open or normally closed. When an external force (such as pressing the button) is applied to overcome the spring force, the valve core moves, switching the flow path state. Once the external force disappears, the potential energy stored in the spring immediately pushes the valve core back to its initial position, achieving automatic reset.

[0046] When the dust cover 10 is in the initial position, the pressing plate 24 presses the button on the valve 19, at which time the valve 19 is in the closed state; conversely, when the pressing plate 24 is separated from the valve 19, the valve 19 is in the open state.

[0047] A shearing method for a shearing device used in processing transformer insulation boards includes the following steps:

[0048] Step 1: The hydraulic cylinder 8 drives the shearing blade 9 to descend. The shearing blade 9 drives the two upper toothed plates 12 to descend synchronously. With the use of the two transmission teeth 13, the two lower toothed plates 14 move upward synchronously. The lower toothed plates 14 drive the dust collection hood 10 to move upward. At the same time, the pressing plate 24 separates from the valve 19, so that the dust collection pipe 25 is in the conducting state, that is, the dust collection hood 10 performs the suction action. When the dust collection hood 10 is in contact with the surface of the conveyor table 1, the shearing blade 9 has completed the cutting operation of the sheet. The sheet falls to the top of the dust collection hood 10. The negative pressure inside the dust collection hood 10 can not only fix the sheet, but also absorb the cutting debris to avoid polluting the surrounding environment.

[0049] Step 2: The hydraulic cylinder 8 then drives the shearing blade 9 to move upward. Through the cooperation of the upper toothed plate 12, the transmission tooth 13, and the lower toothed plate 14, the dust suction hood 10 moves downward to the initial position, simultaneously driving the sheet material to descend. The pressing plate 24 presses against the valve 19, at which point the valve 19 closes, causing the dust suction hood 10 to stop its suction action, thus loosening the sheet material.

[0050] Step 3: The drive mechanism drives the small end of the plate located on the conveyor table 1 to move forward, preparing for subsequent cutting. At the same time, through the coordinated use of two sprockets 30, transmission chain 29, rotating shaft 32, conical tooth 1 33, and conical tooth 2 34, the rotating disk 20 rotates one revolution. In conjunction with the use of the elongated plate 21, the push plate 23 can be driven to move back and forth. The push plate 23 impacts the sheet-like plate on the top of the dust collection hood 10, moving the plate onto the discharge plate 11 to achieve safe unloading and ensure the integrity of the plate.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

The pressing plate (24) presses against the valve (19), at which point the valve (19) closes, causing the dust hood (10) to stop its suction action, thus loosening the sheet material. Step 3: The drive mechanism drives the small end of the plate located on the conveyor table (1) to move forward to prepare for subsequent cutting. At the same time, through the combined use of two sprockets (30), transmission chain (29), rotating shaft (32), conical tooth one (33), and conical tooth two (34), the rotating disk (20) rotates one revolution. With the use of the elongated plate (21), the push plate (23) can be driven to move back and forth. The push plate (23) hits the sheet-like plate on the top of the dust hood (10) and moves the plate to the discharge plate (11) to achieve safe unloading and ensure the integrity of the plate.
