Description

Technical Field

[0001] The present invention relates to the technical field of transformer production, and specifically to a steel sheet stacking and welding tooling for a transformer. Background Technique

[0002] The steel sheets of a transformer usually refer to the iron core part of the transformer. It is composed of multiple stacked thin steel sheets. The function of the steel sheets is to increase the magnetic conductivity of the magnetic flux, reduce magnetic losses (such as eddy current losses), and improve the efficiency of the transformer. The arrangement of these steel sheets is generally to stack them into a magnetic core and complete the conduction of the magnetic field and the conversion of energy by wrapping the windings.

[0003] The steel sheets are usually stacked in a certain order, maintaining a certain gap between each other. Through such a design, the generation of eddy currents can be effectively restricted. The stacking method of the steel sheets is usually staggered, and sometimes oblique slices are used to further reduce eddy current losses. The stacking method of the steel sheets is generally fixed by pressing or spot welding. To ensure the stability and mechanical strength of the iron core, the steel sheets are sometimes connected together by spot welding.

[0004] In the prior art, during the process of stacking the steel sheets, the stacking operation is usually carried out on a set of workbenches. Two staff members need to sit face to face and use positioning blocks. The positioning blocks are placed according to the assembly requirements, and then the stacking of the steel sheets begins. After the steel sheets are stacked, the staff welds the steel sheets. During the welding process, especially when using resistance welding or spot welding, harmful gases or welding fumes may be generated, increasing the workload of the staff, and the harmful gases or welding fumes will have an impact on the health of the staff.

[0058] Please refer to Figure 3 - Figure 10, a second air box 22 is installed inside the device main body 1, and a fan is installed on the outer wall of one end of the output shaft 21 extending into the second air box 22. Two air outlet pipes 23 are installed at the air outlet of the second air box 22, and an air outlet pipe is installed at the air inlet of the second air box 22. Multiple air outlet plates 24 are installed inside the device main body 1, and the multiple air outlet plates 24 are respectively connected to the multiple air outlet pipes 23.

Two contraction cylinders 26 are movably installed inside the device main body 1, and a synchronous belt is connected between the two contraction cylinders 26 and the two transmission cylinders 25 respectively. Telescopic columns 27 are movably installed inside the two contraction cylinders 26, and the inner walls of the two contraction cylinders 26 are respectively threadedly connected to the outer walls of the two telescopic columns 27. Limiting seats 28 are installed at the upper ends of the two telescopic columns 27, and limiting grooves 29 are opened in the two limiting seats 28. Multiple mounting rods 33 are installed inside the device main body 1, and tooth plates 34 are installed at the upper ends of the multiple mounting rods 33. The multiple tooth plates 34 are respectively movably connected to the inner walls of the multiple limiting grooves 29. The two limiting columns 6 move into the two transmission cylinders 25, and the outer walls of the two limiting columns 6 are respectively threadedly connected to the inner walls of the two transmission cylinders 25. Therefore, the two transmission cylinders 25 rotate. The two transmission cylinders 25 and the two contraction cylinders 26 are respectively connected by a synchronous belt. The two contraction cylinders 26 rotate. The inner walls of the two contraction cylinders 26 are respectively threadedly connected to the outer walls of the two telescopic columns 27. Therefore, the two telescopic columns 27 move downward, driving the two limiting seats 28 to move downward.

[0060] Please refer to Figure 3 - Figure 13, multiple sets of pressing plates 30 are movably installed inside both groups of limit seats 28, multiple sets of second limit shafts 31 are movably installed inside both groups of limit seats 28, and the outer walls of the multiple sets of second limit shafts 31 are respectively threadedly connected to the inner walls of the multiple sets of pressing plates 30. One end of each of the multiple sets of second limit shafts 31 is installed with a limit gear 32, and the multiple sets of limit gears 32 are respectively meshed and connected to the multiple sets of toothed plates 34. The two groups of limit seats 28 move downward, thereby driving the multiple sets of pressing plates 30, the multiple sets of second limit shafts 31, and the multiple sets of limit gears 32 to move downward. And the multiple sets of limit gears 32 are respectively meshed and connected to the multiple sets of toothed plates 34, so the multiple sets of limit gears 32 rotate, thereby driving the multiple sets of second limit shafts 31 to rotate. The outer walls of the multiple sets of second limit shafts 31 are respectively threadedly connected to the inner walls of the multiple sets of pressing plates 30, so one ends of the multiple sets of pressing plates 30 respectively move out of the inner walls of the two groups of limit seats 28, such that while the two groups of limit seats 28 move downward, the multiple sets of pressing plates 30 respectively press and fix the multiple sets of steel sheets.

[0061] Please refer to Figure 1 - Figure 3 , multiple sets of support columns 35 are installed inside the device main body 1, and the outer walls of the multiple sets of support columns 35 are respectively movably connected to the inner wall of the base 4, and the outer wall of the base 4 is movably connected to the inner wall of the device main body 1. Multiple sets of reserved holes 36 are opened at the upper end of the device main body 1. The base 4 drives the steel sheet to move downward, and the multiple sets of support columns 35 and the inner wall of the device main body 1 cooperate to limit the steel sheet, avoiding the steel sheet from shifting on the upper end of the base 4. After the multiple sets of air outlet plates 24 discharge the air flow, the air flow is discharged from the inside of the device main body 1 through the multiple sets of reserved holes 36.

[0062] The working principle of the present invention is as follows: When the staff uses this device to perform the stacking and welding tooling operation on the steel sheets of the transformer, the staff places the steel sheets on the upper end of the base 4 one by one. At the same time, the hydraulic pump 2 is started, driving the hydraulic column 3 to slowly move downward, driving the base 4 to slowly move downward. The base 4 drives the steel sheet to move downward, and the multiple sets of support columns 35 and the inner wall of the device main body 1 cooperate to limit the steel sheet, avoiding the steel sheet from shifting on the upper end of the base 4;

[0063] When the base 4 moves downward, it drives the two groups of limit plates 5 and the two groups of limit columns 6 to move downward. The inner wall bumps of the two groups of limit plates 5 are respectively movably connected to the inner wall of the thread grooves on the outer walls of the two groups of first limit shafts 7. Therefore, the two groups of first limit shafts 7 rotate. The setting of the one-way bearing at the bottom end of one of the first limit shafts 7 causes the bottom end of one of the first limit shafts 7 not to rotate. And the two groups of first limit shafts 7 are respectively connected to the two groups of transmission shafts 8 through synchronous belts. The two groups of transmission shafts 8 rotate, and the two groups of transmission shafts 8 are respectively connected to two of the linkage shafts 9 through synchronous belts. Therefore, two of the linkage shafts 9 rotate. The multiple groups of linkage shafts 9 are respectively connected to each other through synchronous belts. Therefore, the multiple groups of linkage shafts 9 rotate synchronously. The outer walls of the multiple groups of linkage shafts 9 are respectively threadedly connected to the inner walls of the multiple groups of mounting seats 10. Therefore, the multiple groups of mounting seats 10 move upward, thereby driving the multiple groups of welding heads 11 to move upward;

[0064] When the multiple groups of linkage shafts 9 rotate, two of the linkage shafts 9 are both connected to the movable shaft 12 through synchronous belts, driving one end of the movable shaft 12 to rotate. Due to the setting of the one-way bearing, the other end of the movable shaft 12 does not rotate;

[0065] The base 4 continues to move downward. The staff stops placing the steel sheets. Then the two groups of limit columns 6 move into the two groups of transmission cylinders 25. The outer walls of the two groups of limit columns 6 are respectively threadedly connected to the inner walls of the two groups of transmission cylinders 25. Therefore, the two groups of transmission cylinders 25 rotate. The two groups of transmission cylinders 25 are respectively connected to the two groups of shrinkage cylinders 26 through synchronous belts. The two groups of shrinkage cylinders 26 rotate. The inner walls of the two groups of shrinkage cylinders 26 are respectively threadedly connected to the outer walls of the two groups of telescopic columns 27. Therefore, the two groups of telescopic columns 27 move downward;

[0066] When the two groups of telescopic columns 27 move downward, they drive the two groups of limit seats 28 to move downward, thereby driving the multiple groups of pressing plates 30, the multiple groups of second limit shafts 31 and the multiple groups of limit gears 32 to move downward. And the multiple groups of limit gears 32 are respectively meshed with the multiple groups of toothed plates 34. Therefore, the multiple groups of limit gears 32 rotate, thereby driving the multiple groups of second limit shafts 31 to rotate. The outer walls of the multiple groups of second limit shafts 31 are respectively threadedly connected to the inner walls of the multiple groups of pressing plates 30. Therefore, one ends of the multiple groups of pressing plates 30 respectively move out of the inner walls of the two groups of limit seats 28. While the two groups of limit seats 28 move downward, the multiple groups of pressing plates 30 respectively press and fix the multiple groups of steel sheets, and the hydraulic pump 2 is closed;

[0067] After multiple groups of steel plates are pressed and fixed, the motor inside the first air box 15 starts, driving the input shaft 14 to rotate. One end of the input shaft 14 extends to one end of the outer wall of the first air box 15 and is connected to the input end of the first speed change gear box 13, thereby conducting kinetic energy into the first speed change gear box 13. The first speed change gear box 13 reduces the rotational speed. One end of the movable shaft 12 is connected to the output end of the first speed change gear box 13, thereby driving the movable shaft 12 to rotate, and then driving two of the linkage shafts 9 to rotate, causing multiple groups of linkage shafts 9 to rotate synchronously, thereby driving one end of the two transmission shafts 8 to rotate. Due to the setting of the one-way bearings at the central ends of the two transmission shafts 8, the other ends of the two transmission shafts 8 do not rotate;

[0068] When multiple groups of linkage shafts 9 rotate, they drive multiple mounting seats 10 to move downward. At the same time, the welding devices inside the multiple mounting seats 10 start, and the pressed steel sheets are welded through multiple welding heads 11, reducing the workload of the staff. Harmful gases are generated during welding;

[0069] When the input shaft 14 rotates, it drives the fan on the outer wall of the input shaft 14 to rotate, causing an air flow to be generated inside the first air box 15. Two suction pipes 16 are installed at the air inlet end of the first air box 15, and the two suction pipes 16 are respectively connected to multiple suction heads 17. The multiple suction heads 17 absorb the harmful gases generated during welding. The air outlet end of the first air box 15 is connected to the air inlet end of the air purification device 19 through an outlet pipe 18. The harmful gases enter the inside of the air purification device 19 through the outlet pipe 18, and the air purification device 19 discharges the treated harmful gases, avoiding the impact of harmful gases on the health of the staff;

[0070] After the pressed steel sheets are welded, the hydraulic pump 2 starts, driving the hydraulic column 3 to move upward, thereby driving the base 4 and the steel sheets to move upward, and then driving the two limit plates 5 to move upward, causing the two first limit shafts 7 to rotate, thereby driving one end of the two transmission shafts 8 to rotate. Due to the setting of the one-way bearings at the central ends of the two transmission shafts 8, the other ends of the two transmission shafts 8 do not rotate. One end of one of the first limit shafts 7 is connected to the input end of the second speed change gear box 20, conducting kinetic energy into the second speed change gear box 20. The second speed change gear box 20 increases the rotational speed. An output shaft 21 is installed at the output end of the second speed change gear box 20, causing the output shaft 21 to rotate;

[0071] When the output shaft 21 rotates, a fan is installed on the outer wall of one end of the output shaft 21 extending into the interior of the second bellows 22, driving the fan to rotate, so that an air flow is generated inside the second bellows 22. The air flow enters from the intake pipe at the intake end of the second bellows 22, and then the air flow is discharged from the two outlet pipes 23 at the outlet end of the second bellows 22. The two outlet pipes 23 are respectively connected to multiple air outlet plates 24, and the air flow is discharged from the multiple air outlet plates 24. At the same time, the welded end of the steel sheet moves upward, and the air flow assists in cooling the welded end of the steel sheet, accelerating the cooling of the welded end of the steel sheet and improving the efficiency of the steel sheet welding tooling.
