Description

Technical Field

[0001] The present invention relates to the field of copper strip trimming, and particularly to a compact transformer copper strip cutting and trimming device. Background Art

[0002] The transformer copper strip cutting and trimming device is a key equipment in the transformer production and manufacturing process. Its core function is to finely trim the cut transformer copper strip, effectively removing the burrs generated during the cutting process to ensure that the quality of the copper strip edge meets high-standard requirements.

[0003] The publication number is CN220145479U, which discloses a device for rounding the edges of a transformer copper strip. It includes a trimming workbench. In the middle of the top of the trimming workbench, a placement table is fixedly connected. The top of the placement table is lapped with a copper strip body. There are grinding and trimming mechanisms on both sides of the copper strip body. The number of the grinding and trimming mechanisms is two. As a key raw material, the quality of the copper strip cutting and trimming directly affects the performance and quality of the transformer. With the rapid development of the power industry and the continuous improvement of the accuracy requirements for transformers, high-precision copper strip processing has become an inevitable trend. The existing transformer copper strip cutting and trimming devices are usually equipped with grinding wheels to remove the burrs on the edge of the copper strip after cutting and perform fine trimming to meet the process requirements such as tightly winding coils. However, in the actual use process, when the grinding wheel processes the copper strip, due to the material characteristics of the copper strip itself and the inherent characteristics of the grinding process, problems arise. The copper strip is mostly made of various copper alloys, with a certain hardness and toughness. During the high-speed grinding process, a large amount of the ground copper chips will adhere to the outside of the grinding wheel. These chips will change the flatness and roughness of the surface of the grinding wheel. The originally evenly distributed abrasive grains cannot fully play the grinding role due to being covered by the chips, making the subsequent contact with the copper strip edge uneven. For example, when there is a large amount of chip accumulation in a certain area of the grinding wheel, the pressure on the copper strip edge in this area will decrease, resulting in incomplete trimming, burrs remaining on the copper strip edge, seriously affecting the insulation performance of the transformer winding, and possibly causing safety hazards such as short circuits.

[0004] To solve the above problems, a compact transformer copper strip cutting and trimming device is proposed. Summary of the Invention

The central axis of the rack 8105 is perpendicular to the upper surface of the base 1, and the height of the rack 8105 is greater than the height of the gear 8104, so that the gear 8104 will rotate when moving horizontally.

[0022] The reciprocating assembly 82 includes a sleeve 8201 fixedly connected to the inner upper surface of the second push rod 8102. A first rotating rod 8202 is fixedly connected to the upper surface of the gear 8104. A second groove 8203 is arranged inside the first rotating rod 8202. A second rotating rod 8204 is arranged inside the second groove 8203. A rotating disk 8205 is fixedly connected to the upper end of the second rotating rod 8204.

Moreover, the outer appearance structure of the second rotating rod 8204 is a cuboid, and the central axis of the second rotating rod 8204 is perpendicular to the upper surface of the gear 8104, so that the second rotating rod 8204 will not rotate or shake when moving up and down inside the second groove 8203.

[0023] On the inner side of the base 1, there is a third groove 10. The elastic mechanism 9 includes a sliding plate 901 that is horizontally slidably connected to the lower part inside the third groove 10. On the inner side of the sliding plate 901, there is a fourth groove 902. Inside the fourth groove 902, a spring 903 is fixedly connected. The upper end of the spring 903 is fixedly connected to a third push rod 904. The third push rod 904 is fixedly connected to the second push rod 8102. Above the inner side of the third groove 10, there is a second guide groove 905 communicated. Below the second guide groove 905, there is a third guide groove 906. The middle of the second guide groove 905 and the third guide groove 906 is communicated through a fourth guide groove 907. Inside the fourth guide groove 907, there is a third guide rod 908 fixedly connected to the third push rod 904. The widths of the second guide groove 905, the third guide groove 906, and the fourth guide groove 907 are all greater than the width of the third guide rod 908. And the outer appearance structures of the second guide groove 905 and the third guide groove 906 are both horizontal straight lines, so that the third guide rod 908 can move up and down inside the second guide groove 905, the third guide groove 906, and the fourth guide groove 907. In the natural state of the spring 903, the height of the third guide rod 908 is the same as the height of the lower surface of the second guide groove 905. The second guide groove 905 and the third guide groove 906 are communicated with a fifth guide groove 910 at one end close to the cylinder 4. Below the inner side of the second guide groove 905 at one end close to the cylinder 4, a baffle 909 is fixedly connected. The upper surface of the baffle 909 is an inclined surface. The fourth guide grooves 907 are equidistantly distributed between the second guide groove 905 and the third guide groove 906. And the outer appearance structure of the fourth guide groove 907 is an inclined straight line, so that the third guide rod 908 can move up and down along the track of the fourth guide groove 907. The distance between the second guide groove 905 and the third guide groove 906 is less than the height of the rack 8105, and the distance between the second guide groove 905 and the third guide groove 906 is greater than the height of the high-temperature resistant nylon brush 8208, so that the gear 8104 will not move out of the control range of the rack 8105.

[0024] Above the copper strip and the bearing plate 2, start the cylinder 4 to drive the air rod 5, the motor 6, and the grinding wheel 7 to move to one side of the bearing plate 2, so that the grinding wheel 7 is close to the copper strip. Start the motor 6 to drive the grinding wheel 7 to perform deburring by grinding. After the grinding is completed, a lot of debris adheres to the outside of the grinding wheel 7, which will affect the subsequent grinding effect and needs to be cleaned. The specific operation is as follows: The starting cylinder 4 drives the air rod 5, the motor 6, and the grinding wheel 7 to move in the direction of the cylinder 4, driving the first push rod 8101 and the second push rod 8102 to move in the direction of the cylinder 4, so that the third push rod 904 is driven by the second push rod 8102 to move in the direction of the cylinder 4. At this time, the third guide rod 908 is located inside the fourth guide groove 907, and the outer structure of the third guide groove 906 is an inclined straight line shape, causing the second push rod 8102 to move in the direction of the cylinder 4, so that the third push rod 904 drives the third guide rod 908 to move upward along the track of the fourth guide groove 907, driving the third push rod 904, the second push rod 8102, and the gear 8104 to move upward. Because the distance between the second guide groove 905 and the third guide groove 906 is smaller than the height of the rack 8105, and when the spring 903 is in the natural state, the height of the third guide rod 908 is the same as the lower surface height of the second guide groove 905, enabling the third guide rod 908 to move into the inner side of the second guide groove 905. At this time, after the gear 8104, the second push rod 8102, the rotating disk 8205, and the high-temperature resistant nylon brush 8208 move upward, the spring 903 is in the natural state, and the high-temperature resistant nylon brush 8208 contacts the outer side of the grinding wheel 7. The cylinder 4 continues to drive the air rod 5 to move in the direction of the cylinder 4. Because the connection mode between the second push rod 8102 and the gear 8104 is a rotating connection, the gear 8104 moves in the direction of the cylinder 4. Since the gear 8104 meshes with the rack 8105, the gear 8104 rotates to drive the first rotating rod 8202 and the second rotating rod 8204 to move, causing the rotating disk 8205 and the first guide rod 8207 to rotate. Because the outer structure of the first guide groove 8206 is "V"-shaped, and there are multiple "V"-shaped first guide grooves 8206, and the first guide grooves 8206 communicate with each other, the first guide rod 8207 is pushed by the first guide groove 8206 to move up and down reciprocally, driving the rotating disk 8205 and the high-temperature resistant nylon brush 8208 to rotate and move up and down, cleaning the grinding wheel 7 in multiple directions, making the subsequent grinding and deburring effect better. At this time, the suction fan 11 is started to suck away the debris cleaned up.

[0025] When the air cylinder 4 drives the air rod 5 to move the third guide rod 908 to the baffle 909, the third guide rod 908 then moves upward along the upper surface bevel of the baffle 909 and reaches the side of the baffle 909 close to the air cylinder 4. Since the height of the third guide rod 908 is the same as the lower surface height of the second guide groove 905 in the natural state of the spring 903, when it is necessary to clean the copper plate again, the air cylinder 4 is started to drive the air rod 5 to drive the corresponding first push rod 8101, second push rod 8102, third push rod 904 and third guide rod 908 to move towards the side of the bearing plate 2. Since the third guide rod 908 is blocked by the baffle 909 and cannot move into the inner side of the second guide groove 905, the third guide rod 908 moves along the trajectory passing through the fifth guide groove 910 to the inner side of the third guide groove 906, causing the rotating disk 8205, high-temperature resistant nylon brush 8208, etc. to move downward as a whole. Since the widths of the second guide groove 905, third guide groove 906 and fourth guide groove 907 are all greater than the width of the third guide rod 908, and the fourth guide grooves 907 are evenly distributed between the second guide groove 905 and the third guide groove 906, when the grinding wheel 7 contacts the outer side of the copper plate, the third guide rod 908 is inside the third guide groove 906, or the elastic potential energy of the spring 903 pushes the third guide rod 908 upward to move into the inner side of the fourth guide groove 907 to prepare for the next cleaning. When the third guide rod 908 is inside the third guide groove 906, when the third guide rod 908 moves towards the side of the air cylinder 4, the position of the third guide rod 908 coincides with that of the third guide groove 906, and the elastic potential energy of the spring 903 pushes the third guide rod 908 upward to move into the inner side of the fourth guide groove 907 for the next cleaning, and timely cleaning can still be provided when adapting to copper plates of different widths.

[0026] When the air cylinder 4 drives the air rod 5 to drive the motor 6 and the grinding wheel 7 to approach the copper plate, at this time the gear 8104 and the rack 8105 are still in contact, enabling the first rotating rod 8202, second rotating rod 8204, rotating disk 8205 and high-temperature resistant nylon brush 8208 to still rotate and move up and down. At this time, the high-temperature resistant nylon brush 8208 has separated from the outer side of the grinding wheel 7, so that the impurities inside the high-temperature resistant nylon brush 8208 can be thrown out under the action of inertia, making the cleaning effect better next time.

[0027] Since the distance between the second guide groove 905 and the third guide groove 906 is greater than the height of the high-temperature resistant nylon brush 8208, when the third guide rod 908 is inside the third guide groove 906, the horizontal height of the high-temperature resistant nylon brush 8208 is lower than the horizontal height of the rack 8105. At this time, the impurities inside the high-temperature resistant nylon brush 8208 can be thrown out under the action of inertia and will be blocked by the rack 8105, reducing the diffusion direction of the impurities, reducing the distribution of the impurities and reducing the harm of the thrown-out impurities to the personnel.

[0028] Since the upper surface of the rotating disk 8205 is fixedly connected with a plurality of high-temperature resistant nylon brushes 8208, when the high-temperature resistant nylon brushes 8208 rotate and move up and down to clean the grinding wheel 7, the plurality of high-temperature resistant nylon brushes 8208 clean simultaneously, improving the cleaning effect.

[0029] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
