Description

Technical Field

[0001] This invention belongs to the field of cathode wire processing technology, specifically a cathode wire stamping and forming device for electrostatic precipitators. Background Technology

[0002] Electrostatic precipitators are key equipment in industrial flue gas purification systems. One of their core components is the cathode wire, whose main function is to generate corona discharge, charging dust particles and capturing them under the influence of an electric field. The geometry, dimensional accuracy, and surface quality of the cathode wire directly affect the dust removal efficiency and operational stability of the electrostatic precipitator. Therefore, it must undergo a strict stamping and forming process during manufacturing to ensure that the wire meets the specified shape, strength, and consistency.

[0003] Existing equipment for processing cathode wires in electrostatic precipitators typically uses ordinary stamping presses or simple molds for forming. These devices generally only have a single stamping power mechanism and a fixed mold. During operation, the wire must be placed manually, positioned manually, and the stamping triggered manually. This not only results in low production efficiency but also easily leads to problems such as positioning deviations and inconsistent forming dimensions in mass production. Furthermore, since cathode wire materials are mostly thin steel wires or special alloy wires with low rigidity and high springback, the forming force of traditional stamping equipment is difficult to control precisely, easily causing scratches, deformation, or even breakage of the wire surface, affecting the finished product qualification rate. Summary of the Invention

[0012] Preferably, the conveying component includes a first stabilizing frame fixedly installed on one side of the base near the middle position. Several conveying rollers are arranged on opposite sides of the inner cavity of the first stabilizing frame, with adjacent two conveying rollers arranged vertically. A movable shaft is movably inserted through the front side of each conveying roller, and both ends of the movable shaft pass through the inner cavity sidewall of the first stabilizing frame through bearings. Rotary gears are fixedly sleeved on the outer periphery of two movable shafts on one side near the front end, and the rotating gears are meshed with each other. A first load-bearing plate is fixedly installed on the front side of the first stabilizing frame near one side, and a servo motor is fixedly installed on the top of the first load-bearing plate. The power output shaft of the servo motor is fixedly connected to the adjacent movable shaft. Second synchronous pulleys are fixedly installed at the rear ends of several movable shafts, and adjacent two second synchronous pulleys are connected by a second synchronous belt drive.

[0013] Preferably, the auxiliary moving component includes two mounting plates installed on the top of the placement plate on the other side. The mounting plates are rotatably connected to a fixed shaft on opposite sides. A pressing roller is fixedly sleeved on the outer periphery of the fixed shaft, and a ratchet is fixedly sleeved near the rear end of the outer periphery of the fixed shaft.

[0014] Preferably, the outer circumference of the pressing roller is provided with a plurality of grooves at equal intervals, and a rubber block is fixedly installed in the inner cavity of each groove. A squeezing block is fixedly installed at the end of each rubber block, and the squeezing block moves through the inner cavity of the groove.

[0015] Preferably, the winding component includes a second stabilizing frame fixedly installed on the other side of the base.

[0016] The beneficial effects of this invention are as follows: 1. By incorporating stamping components, the lower and upper dies can close during the rotation of the eccentric wheel, thus completing the stamping process of the cathode wire raw material. The T-shaped plate threaded to the outer circumference of the threaded rod can be removed by rotating the threaded rod, facilitating the replacement of the new die. This design can meet the stamping requirements of cathode wires of different specifications, effectively expanding the application range of the device.

[0017] 2. By setting up support components, the top plate can move upward, thereby lifting the waste material from the stamping of the cathode wire. When the upper die 17 stamps downward, the top plate can effectively support the stamping position of the cathode wire, preventing the stamping edge from being bent, thus improving the stamping quality. In addition, when the top plate moves upward, it can also flatten the cathode wire, preventing the stamped cathode wire from twisting, ensuring that it remains flat, and reducing damage to the cathode wire raw material.

[0018] 3. By incorporating an auxiliary moving component, the ratchet and pawl's one-way engagement characteristic ensures smooth material passage. During raw material transport, the pawl slides on the back of the ratchet teeth, preventing counter-clockwise rotation and ensuring unimpeded passage. If the raw material initially tends to slide backward due to unforeseen circumstances, the pawl, under the elastic restoring force of the torsion spring, firmly engages with the ratchet teeth, preventing counter-clockwise rotation and effectively preventing backward sliding of the raw material, thus ensuring its positional stability along the transport path.

[0019] 4. By setting up a take-up mechanism, the length of the cathode wire wound in one revolution of the take-up roller is not consistent during the continuous winding process, while the amount of cathode wire fed is constant. Through the friction wheel drive, it is ensured that the cathode wire always maintains appropriate tension during the winding process, and the cathode wire is prevented from shrinking back.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 12 As shown, an electrostatic precipitator cathode wire stamping forming device includes a base 1; a PLC controller 2 is fixedly installed on the front side of the base 1 near one side; a support member is provided at the middle position of the top of the base 1; placement plates 3 are fixedly installed on the top of the base 1 near both sides (both placement plates 3 are provided with irregular grooves adapted to the cathode wire); a pressing member is provided on the top of one placement plate 3; a conveying member is provided on one side of the base 1; a winding member is provided on the other side of the base 1; an auxiliary moving member is provided on the top of the other placement plate 3; and a stamping member is provided on the top of all the placement plates 3. like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, the stamped part includes a fixed frame 4 that is fixedly mounted on the top of two placement plates 3. A first T-shaped rod 5 is movably inserted through the top of the fixed frame 4 near its perimeter. A connecting block is fixedly installed at the bottom of each first T-shaped rod 5, and a fixed plate 7 is installed on the top of each connecting block. A return spring 6 is movably sleeved on the outer periphery of each first T-shaped rod 5 near its top end. Both ends of the return spring 6 are fixedly connected to the first T-shaped rod 5 and the fixed frame 4, respectively. A first drive motor 8 is fixedly installed at the middle of the top of the fixed frame 4. A stabilizing plate is fixedly installed at the bottom of the fixed frame 4, and a transmission rod 11 is movably inserted through the rear side of the stabilizing plate via a bearing. An eccentric wheel is fixedly installed at the front end of the transmission rod 11. 12. The transmission rod 11 and the power output shaft of the first drive motor 8 are both fixedly mounted with the first synchronous pulley 10, and the first synchronous pulley 10 are connected by the first synchronous belt 9. The front side of the fixed plate 7 is provided with a T-shaped groove 13, and the inner cavity of the T-shaped groove 13 is fixedly mounted with a support plate 14. The front side of the support plate 14 is movably connected with a threaded rod 15 (the opposite end of the threaded rod 15 is provided with a hexagonal countersunk groove). The outer periphery of the threaded rod 15 is threaded with a T-shaped plate 16 near the front and rear ends. The bottom of the T-shaped plate 16 is fixedly mounted with an upper mold 17, and the top middle position of the base 1 is fixedly mounted with a lower mold 18 (the lower mold 18 is provided with a special-shaped groove adapted to the cathode wire).

[0025] Specifically, during the cathode wire stamping operation, the cathode wire raw material to be processed is first accurately placed on the top of the lower mold 18. Then, the first drive motor 8 is started, and its power output shaft drives the first synchronous wheel 10 fixed thereto to rotate. Through the transmission of the first synchronous belt 9, another first synchronous wheel 10 rotates accordingly, thereby driving the transmission rod 11 to rotate. This enables the eccentric wheel 12 fixed at the front end of the transmission rod 11 to rotate and continuously press down on the fixed plate 7. Under the downward pressure of the eccentric wheel 12, the fixed plate 7 moves downward along the first T-shaped rod 5. At this time, the return spring 6 on the outer periphery of the first T-shaped rod 5 is compressed and stores elastic potential energy. The downward movement of the fixed plate 7 synchronously drives the upper mold 17 at the bottom to move closer to the lower mold 18. When the lower mold 18 and the upper mold 17 close, the stamping process of the cathode wire raw material is completed. After stamping, the first drive motor 8 continues to run, and the eccentric wheel 12 rotates to a position where it no longer applies pressure to the fixed plate 7. The return spring 6 releases its elastic potential energy, pushing the connecting block and the fixed plate 7 upward to reset, thereby successfully separating the upper mold 17 from the lower mold 18. If it is necessary to stamp cathode wires of different specifications and sizes, the two upper molds can be adjusted by rotating the threaded rod 15 clockwise through the hexagonal countersunk groove. The distance between the molds 17 is such that the threads on the outer periphery of the threaded rod 15 have opposite directions of rotation near the front and rear ends. When the threaded rod 15 is rotated, the two T-shaped plates 16 will move in opposite directions along the front side of the support plate 14 within the T-shaped groove 13 until the T-shaped plates 16 move out of the T-shaped groove 13. When a new mold needs to be replaced, the two T-shaped plates 16 are removed and then placed on the outer periphery of the threaded rod 15. The hexagonal recess is driven by rotating counterclockwise, and a new mold can be installed on the outer periphery of the threaded rod 15. This allows for the stamping of cathode wires of different specifications, thus improving the application range of the device.

[0026] like Figure 7 As shown, the outer periphery of the threaded rod 15 is provided with external threads in opposite directions, and the initial positions of the external threads are the same. The T-shaped plates 16 are all provided with internal threads that are compatible with the threaded rod 15, and the initial positions of the internal threads are the same.

[0027] Specifically, left-handed and right-handed external threads are machined on the outer circumferential surfaces of both ends of the threaded rod 15. The starting points of these two threads are located on the same plane in the axial direction of the threaded rod 15, ensuring that when the threaded rod 15 starts to rotate, the two T-shaped plates 16 can simultaneously connect with the outer circumferential threads of the threaded rod 15 and move in opposite directions in equal amounts. This makes the spacing adjustment process between the two upper dies 17 more precise and synchronized, avoiding die misalignment or adjustment errors caused by asynchronous initial thread positions. This ensures that the stamping position of the cathode wire raw material is always accurate when changing or adjusting the die, further improving the stamping precision and product consistency.

[0028] like Figure 9 and Figure 10As shown, the support includes a mold groove 19 opened on the top of the lower mold 18 near the front and rear sides. The inner cavity of the mold groove 19 is slidably connected to a top plate 20. Several recesses are opened on the inner cavity of the mold groove 19 and the opposite side of the adjacent top plate 20. A connecting spring 21 is provided between two adjacent recesses.

[0029] Specifically, the upper die 17 moves downward to press the top plate 20, causing the top plate 20 to move downward against the elastic force of the connecting spring 21. The connecting spring 21 is compressed and stores elastic potential energy. When the stamping is completed and the upper die 17 returns to its original position, the compressed connecting spring 21 begins to release its elastic potential energy, enabling the top plate 20 to move upward and lift the waste material of the stamped cathode wire. When the upper die 17 stamps downward, the top plate 20 can effectively support the stamping position of the cathode wire, preventing the stamping edge from being bent, thereby improving the stamping quality. In addition, when the top plate 20 moves upward, it can flatten the cathode wire, preventing the stamped cathode wire from twisting and the teeth formed after stamping from colliding with the side wall of the die groove 19, causing bending deformation and reducing damage to the cathode wire raw material.

[0030] like Figure 10 As shown, L-shaped grooves 22 are provided on the top of both top plates 20.

[0031] Specifically, when the top plate 20 needs to be replaced, the L-shaped groove 22 provides the user with a space to easily pick up the top plate 20, making it easy to replace when the top plate 20 is worn or damaged, effectively improving maintenance efficiency.

[0032] like Figure 9 As shown, electromagnets 23 are fixedly installed on opposite sides of the two placement plates 3, and electromagnets 23 are connected to the PLC controller 2 via electrical signals.

[0033] Specifically, after the stamping process is completed, the generated waste is attracted by the magnetic force generated by the energized electromagnet 23. The direction of the electromagnet 23 in the waste bin moves and is attracted by the electromagnet 23. After the electromagnet 23 is de-energized, the waste falls naturally under the action of gravity and falls into the collection groove that is pre-placed in front of the base 1, which facilitates the collection of waste. There is no need to stop the machine to process the waste, and the cathode wire can be continuously stamped.

[0034] like Figure 2 As shown, the pressing component includes a pressing plate 24 located on the top of a side placement plate 3. A second T-shaped rod 25 is movably inserted through the top of the pressing plate 24 near its periphery, and the bottom end of the second T-shaped rod 25 is fixedly connected to the adjacent placement plate 3. A pressing spring 26 is movably sleeved on the outer periphery of the second T-shaped rod 25, and the two ends of the pressing spring 26 are fixedly connected to the end of the second T-shaped rod 25 and the pressing plate 24, respectively.

[0035] Specifically, when the stamping die stamps the cathode wire raw material, the pressing plate 24 continuously applies pressure to the cathode wire under the elastic force of the pressing spring 26, effectively preventing the cathode wire from being lifted when the upper die 17 moves upward, thus avoiding deformation of the cathode wire due to stress. At the same time, if the cathode wire moves upward and impacts the pressing plate 24, the cathode wire is less likely to warp under the elastic force of the pressing spring 26, thereby ensuring the accuracy of the stamping position and the dimensional accuracy of the formed cathode wire.

[0036] like Figure 1 and Figure 5 As shown, the conveying component includes a first stabilizing frame 27 fixedly installed on one side of the base 1 near the middle position. Several conveying rollers 32 are arranged on opposite sides of the inner cavity of the first stabilizing frame 27, and two adjacent conveying rollers 32 are arranged vertically. The front side of each conveying roller 32 is movably connected to a movable shaft 30, and both ends of the movable shaft 30 pass through the inner cavity sidewall of the first stabilizing frame 27 through bearings. Rotary gears 31 are fixedly sleeved on the outer periphery of two movable shafts 30 on one side near the front end, and the rotating gears 31 are meshed with each other. A first load-bearing plate 28 is fixedly installed on the front side of the first stabilizing frame 27 near one side, and a servo motor 29 is fixedly installed on the top of the first load-bearing plate 28. The power output shaft end of the servo motor 29 is fixedly connected to the adjacent movable shaft 30. The rear ends of several movable shafts 30 are fixedly installed with second synchronous pulleys 33, and two adjacent second synchronous pulleys 33 are connected by a second synchronous belt 34.

[0037] Specifically, when the servo motor 29 starts, its power output shaft drives the movable shaft 30 fixedly connected to it to rotate. The rotating gear 31 at the front end of the movable shaft 30 rotates accordingly. Since the two rotating gears 31 mesh with each other, they drive the other movable shaft 30 to rotate in the opposite direction, realizing the reverse rotation of the two conveying rollers 32 set up vertically. At the same time, the second synchronous pulleys 33 at the rear end of all the movable shafts 30 form a synchronous transmission through the second synchronous belt 34, ensuring that all conveying rollers 32 on the same side can maintain a consistent speed and direction of rotation. This allows the cathode wire raw material to be processed to be stably and continuously clamped between the upper and lower conveying rollers 32 and conveyed at a uniform speed towards the forming mechanism. This conveying method can effectively avoid slippage, deviation or jamming of the raw material during the conveying process, ensuring accurate feeding of the subsequent stamping and forming process.

[0038] like Figure 2 , Figure 4 and Figure 12As shown, the auxiliary moving parts include two mounting plates 35 installed on the top of the placement plate 3 on the other side. The mounting plates 35 are rotatably connected to a fixed shaft 37 on opposite sides. A pressing roller 36 is fixedly sleeved on the outer periphery of the fixed shaft 37. A ratchet 38 is fixedly sleeved near the rear end of the outer periphery of the fixed shaft 37. A pawl 39 is engaged at the top of the ratchet 38. A support rod 40 is fixedly installed on the rear side of the pawl 39. The rear end of the support rod 40 is rotatably connected to the mounting plate 35. A torsion spring 41 is movably sleeved at the middle position of the outer periphery of the support rod 40. One end of the torsion spring 41 is fixedly connected to the support rod 40. A stabilizing rod 42 is fixedly installed on the other end of the torsion spring 41. The rear side of the stabilizing rod 42 is fixedly connected to the mounting plate 35.

[0039] Specifically, when the cathode wire raw material is conveyed forward by the conveyor roller 32 and passes under the pressing roller 36, the raw material will contact the outer periphery of the pressing roller 36. As the raw material continues to move forward, the pressing roller 36 can rotate. Due to the one-way engagement characteristic of the ratchet 38 and the pawl 39, the pawl 39 slides on the back of the teeth of the ratchet 38, which will not hinder the counterclockwise rotation of the ratchet 38, ensuring that the raw material can pass smoothly. When the cathode wire is stamped, if the cathode wire tends to move backward, the pawl 39 will be tightly engaged in the tooth groove of the ratchet 38 under the elastic restoring force of the torsion spring 41, preventing the ratchet 38 from rotating counterclockwise. In turn, the pressing roller 36 is restricted to reverse through the fixed shaft 37, effectively preventing the raw material from sliding backward and ensuring the positional stability of the raw material on the conveying path. This, combined with the conveying action of the conveyor roller 32, provides a reliable material position guarantee for the precise stamping in the early stage.

[0040] like Figure 12 As shown, a number of grooves 43 are equidistantly provided on the outer periphery of the pressure roller 36. A rubber block 44 is fixedly installed in the inner cavity of each groove 43. An extrusion block 45 is fixedly installed at the end of each rubber block 44, and the extrusion block 45 moves through the inner cavity of the groove 43.

[0041] Specifically, when the raw material comes into contact with the outer periphery of the pressing roller 36, the extrusion block 45 will first come into contact with the surface of the raw material. Due to the good elasticity of the rubber block 44, the rubber block 44 will undergo compression deformation, causing the extrusion block 45 to shrink into the groove 43, thereby closely conforming to the surface contour of the raw material. The extrusion block 45 that is not in contact with the raw material will extend out and get stuck between the teeth formed after stamping, so as to avoid relative sliding between the raw material and the pressing roller 36 during normal conveying, effectively preventing the raw material from sliding backward and ensuring the positional stability of the raw material on the conveying path.

[0042] like Figure 8 and Figure 11As shown, the winding component includes a second stabilizing frame 46 fixedly installed on the other side of the base 1. A winding roller 52 is provided on the opposite side of the inner cavity of the second stabilizing frame 46. A movable rod 51 is provided through the front side of the winding roller 52, and the front end of the movable rod 51 is rotatably connected to the front side of the inner cavity of the second stabilizing frame 46. The rear end of the movable rod 51 is movably passed through the rear side of the inner cavity of the second stabilizing frame 46 through a bearing and a second friction wheel 50 is fixedly installed thereon. A second load-bearing plate 47 is fixedly installed on the rear side of the second stabilizing frame 46 near the other side. A second drive motor 48 is fixedly installed on the top of the second load-bearing plate 47, and a first friction wheel 49 is fixedly installed on the end of the power output shaft of the second drive motor 48. The top of the first friction wheel 49 is in close contact with the second friction wheel 50.

[0043] Specifically, when the second drive motor 48 starts, its power output shaft drives the first friction wheel 49 to rotate. Since the first friction wheel 49 and the second friction wheel 50 are in close contact, under the action of friction, the first friction wheel 49 drives the second friction wheel 50 to rotate synchronously, which in turn drives the take-up roller 52 to rotate in the inner cavity of the second stabilizer 46 through the movable rod 51. The cathode wire raw material, which has been stamped and processed by the forming mechanism, is fixed at one end to the outer circumference of the take-up roller 52. As the take-up roller 52 continues to rotate, the raw material will be wound around the take-up roller 52 in an orderly manner, realizing the automatic take-up function of the processed material. During the continuous take-up process, the length of the cathode wire taken up by the take-up roller 52 in one rotation is not consistent, while the amount of cathode wire conveyed is constant. Through the friction wheel transmission, it is ensured that the cathode wire always maintains an appropriate tension during the take-up process, avoiding the phenomenon of cathode wire shrinkage.

[0044] During operation, the cathode wire stamping and forming device of the electrostatic precipitator first continuously feeds the cathode wire raw material to be processed into the processing area through the conveyor on one side of the base 1: the servo motor 29 starts, driving the connected movable shaft 30 to rotate. The rotating gear 31 on the shaft meshes with the gear on another movable shaft 30, so that the upper and lower conveyor rollers 32 rotate synchronously in opposite directions. Under the linkage of the second synchronous wheel 33 and the second synchronous belt 34, the rotation speed of all conveyor rollers 32 on the same side is kept consistent, thereby stably clamping the cathode wire and conveying it forward at a uniform speed. During the conveying process, the pressing roller 36 of the auxiliary moving part contacts the raw material. The rubber block 44 and the extrusion block 45 in the outer groove 43 can fit against the surface of the wire to prevent slippage. When the wire moves forward, the pressing roller 36 rotates accordingly. The ratchet 38 and the pawl 39 achieve one-way limit under the action of the torsion spring 41 to prevent the wire from accidentally retreating and ensure accurate positioning. During the cathode wire stamping process, the cathode wire raw material to be processed is first accurately placed on the top of the lower mold 18. Then, the first drive motor 8 is started, and its power output shaft drives the first synchronous wheel 10 fixed thereto to rotate. Through the transmission of the first synchronous belt 9, another first synchronous wheel 10 rotates accordingly, thereby driving the transmission rod 11 to rotate. This enables the eccentric wheel 12 fixed at the front end of the transmission rod 11 to rotate and continuously press down on the fixed plate 7. Under the downward pressure of the eccentric wheel 12, the fixed plate 7 moves downward along the first T-shaped rod 5. At this time, the return spring 6 on the outer periphery of the first T-shaped rod 5 is compressed and stores elastic potential energy. The downward movement of the fixed plate 7 synchronously drives the upper mold 17 at the bottom to move closer to the lower mold 18. When the lower mold 18 and the upper mold 17 close, the stamping process of the cathode wire raw material is completed. After stamping, the first drive motor 8 continues to run, and the eccentric wheel 12 rotates to a position where it no longer applies pressure to the fixed plate 7. The return spring 6 releases its elastic potential energy, pushing the connecting block and the fixed plate 7 upward to reset, thereby successfully separating the upper mold 17 from the lower mold 18. If it is necessary to stamp cathode wires of different specifications and sizes, the two upper molds can be adjusted by rotating the threaded rod 15 clockwise through the hexagonal countersunk groove. The distance between the molds 17 is such that the threads on the outer periphery of the threaded rod 15 near the front and rear ends turn in opposite directions. When the threaded rod 15 is rotated, the two T-shaped plates 16 will move in opposite directions along the front side of the support plate 14 within the T-shaped groove 13 until the T-shaped plates 16 move out of the T-shaped groove 13. When a new mold needs to be replaced, the two T-shaped plates 16 are removed and then placed on the outer periphery of the threaded rod 15. The hexagonal recess is rotated counterclockwise to drive the new mold to be installed on the outer periphery of the threaded rod 15, thereby enabling the stamping of cathode wires of different specifications and improving the application range of the device. During the downward movement of the stamping waste, the electromagnet 23 is attracted to the waste material. When the waste material moves to the outside of the magnetic zone with the wire, the electromagnet 23 is de-energized, and the waste material falls into the collection device by gravity, realizing continuous waste discharge without stopping the machine. The stamped cathode wire continues to move forward to the winding part: the second drive motor 48 drives the first friction wheel 49 to rotate, and drives the second friction wheel 50 and the winding roller 52 to rotate through friction, so as to wind the finished cathode wire in an orderly manner. The friction wheel drive can adapt to the change of winding length, maintain the tension of the wire, and prevent shrinkage.
