With the continuous upgrading and diversification of household appliances, the requirements for the performance and quality of small transformers are gradually increasing. As one of the core components of small transformers, the quality and dimensional accuracy of the core will directly affect the performance and efficiency of the transformer. However, in the production process of transformer cores, it is necessary to use shearing equipment to cut the original core plate to form a specific size to ensure product consistency. However, when some shearing equipment is used, it is very difficult to collect the cut products.

[0003] After retrieval, Chinese Patent Publication No.: CN221158737U discloses a transformer core shearing equipment, which includes a fixed bottom plate, a conveying mechanism, a shearing mechanism, a tool changing mechanism and a transmission mechanism.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Referring to Figure 1 - Figure 3 , an embodiment provided by the present invention: An iron core shearing device for producing small household appliance transformers, including a processing table 1. The processing table 1 is a prior art, and the iron core to be sheared can be placed on it for processing, and those skilled in the art can implement it. Since it is a prior art, it will not be described in detail in this case. A support frame 2 is fixedly connected to the upper surface of the processing table 1. The support frame 2 can ensure the stability of the shearing device. Inside the top of the support frame 2, there is a shearing plate 3. The shearing plate 3 is a prior art, which is composed of a driving member, a blade mounting seat and a blade, and those skilled in the art can implement it. Since it is a prior art, it will not be described in detail in this case. The inner wall of the bottom end of the support frame 2 is fixedly connected with a shearing table 7. The shearing table 7 is L-shaped to ensure that the cut product can fall smoothly. A positioning component is arranged on the upper surface of the right end of the processing table 1. A chute 6 is opened on the upper surface of the processing table 1 adjacent to the left side of the support frame 2. A guiding component is arranged on the upper surface of the processing table 1 adjacent to the left side of the support frame 2. The positioning component includes a slide rail 45. The slide rail 45 ensures the stability of the movement of the slider 46. The slider 46 is slidably connected to the inner wall of the slide rail 45. A clamping block 44 is fixedly connected to the upper surface of the slider 46. When the shearing plate 3 descends, it will drive multiple groups of clamping blocks 44 to move forward and backward respectively through the cooperation between the round rod 41, the slide plate 42 and the rectangular shell 43, ensuring that the product can smoothly fall between multiple groups of clamping blocks 44. When the shearing plate 3 ascends, multiple groups of clamping blocks 44 will move in the reverse direction to position and clamp the product, ensuring that the product can be placed neatly, improving the practicability. The lower surface of the left end of the clamping block 44 is slidably connected to the upper surface of the right end of the shearing table 7.

[0032] Referring to Figure 1 - Figure 2 、 Figure 4 , the guiding component includes a moving plate 56 that can make the guiding plate 54 move stably. The moving plate 56 is slidably connected to the inner wall of the chute 6. A guiding plate 54 is fixedly connected to the upper surface of the moving plate 56. The left end of the rear surface of the guiding plate 54 is set as an inclined surface. The set inclined surface ensures that the iron core can smoothly enter between multiple groups of guiding plates 54. The lower surface of the guiding plate 54 slides on the upper surface of the processing table 1 adjacent to the left side of the support frame 2. A roller 55 is rotatably connected to the inner wall of the guiding plate 54. The roller 55 can ensure the smooth movement of the iron core.

[0033] Reference Figure 1 、 Figure 3 Moreover, the positioning assembly further includes a round rod 41 fixedly connected to the right surface of the shear plate 3. A slide plate 42 is slidably connected to the outer wall of the right end of the round rod 41. By adjusting the connection distance between the slide plate 42 and the rectangular shell 43, the clamping block 44 can be controlled to clamp and position products of different sizes. The outer wall of the slide plate 42 is slidably connected to a rectangular shell 43. The left surface of the bottom end of the rectangular shell 43 is rotatably connected to the right surface of the top end of the clamping block 44. Multiple groups of grooves are formed in the right surface of the slide plate 42. The multiple groups of grooves are the limiting points of the slide plate 42 at different positions. A limiting rod 47 is slidably connected through the right surface of the top end of the rectangular shell 43. The left surface of the limiting rod 47 contacts the inner wall of the groove. A spring 48 is sleeved on the outer wall of the limiting rod 47. The spring 48 always pulls the limiting rod 47 to move leftward through its own elasticity to ensure the stability of its limitation. One end of the spring 48 is fixedly connected to the right surface of the rectangular shell 43, and the other end of the spring 48 is fixedly connected to the left surface of the limiting rod 47.

[0034] Reference Figure 2 、 Figure 4 Furthermore, a bidirectional threaded rod 51 is threadedly connected through the front surface of the guide plate 54. The bidirectional threaded rod 51 is a prior art, which is a rod-shaped structure with two sets of threads with different helix directions on its outer wall. When it rotates, the structures threadedly connected to its outer wall will move linearly, and at the same time, it does not have the self-locking characteristic. As long as the guide plate 54 moves, it will drive the bidirectional threaded rod 51 to move. The bidirectional threaded rod 51 is rotatably connected through the top end of the front surface of the processing table 1, and the bidirectional threaded rod 51 is rotatably connected through the front surface of a cylindrical shell 52. The guiding assembly further includes the cylindrical shell 52 fixedly connected to the front surface of the top end of the processing table 1. A scroll spring 53 is sleeved on the outer wall of the bidirectional threaded rod 51. The scroll spring 53 has certain characteristics to ensure that multiple groups of guide plates 54 can provide a stable guiding effect on the iron core. One end of the scroll spring 53 is fixedly connected to the outer wall of the bidirectional threaded rod 51, and the other end of the scroll spring 53 is fixedly connected to the inner wall of the cylindrical shell 52.

[0035] Working principle: When in use, when starting the shear plate 3 to cut the product, the vertically moving shear plate 3 will drive the round rod 41 to move. At this time, the inner wall of the top end of the sliding plate 42 will slide circumferentially on the outer wall of the round rod 41. At the same time, the sliding plate 42 will drive the rectangular shell 43 to move. A rotation will occur between the left surface of the bottom end of the rectangular shell 43 and the right surface of the clamping block 44, and at the same time, the clamping block 44 will be driven to move left or right. In this way, it can be ensured that when the shear plate 3 descends, multiple groups of clamping blocks 44 will be driven to move forward and backward respectively through the cooperation among the round rod 41, the sliding plate 42 and the rectangular shell 43, ensuring that the product can smoothly fall between multiple groups of clamping blocks 44. When the shear plate 3 rises, multiple groups of clamping blocks 44 will move in the reverse direction to position and clamp the product, ensuring that the product can be placed neatly.

[0036] The connection distance between the sliding plate 42 and the rectangular shell 43 can be adjusted to control multiple groups of clamping blocks 44 to clamp products of different sizes. Only need to pull the limit rod 47 away from the inner wall of the groove, and the limit rod 47 will stretch the spring 48. In this way, the connection distance between the sliding plate 42 and the rectangular shell 43 can be adjusted, and the position of the clamping block 44 will also move accordingly. After the adjustment is completed, release the limit rod 47, and the spring 48 will drive the limit rod 47 to move in the reverse direction and insert into the inner wall of the groove through its own elasticity.

[0037] Through some components on the processing table 1, before the product is sent below the shear plate 3, the product will contact the guide plate 54 and move along its inclined surface. The guide plate 54 will drive its rotation through the non-self-locking thread of the bidirectional threaded rod 51. The bidirectional threaded rod 51 will drive the scroll spring piece 53 to twist and deform. In this way, with the cooperation of multiple groups of guide plates 54, the iron core can be positioned and guided, improving the practicability.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
