Description

Technical Field

[0001] The utility model relates to the field of transformer iron core production, in particular to a die pressing device for transformer iron core production. Background Art

[0002] The transformer core is the main magnetic circuit part of the transformer. It is usually made of hot-rolled or cold-rolled silicon steel sheets with high silicon content and coated with insulating paint. The core and the coil wound on it form a complete electromagnetic induction system. During the production process of the transformer core, the core raw material is placed on the die pressing device and the die is pressed from top to bottom by the pressure head on the device.

[0003] For example, the patent document with the announcement number CN219591255U discloses a die pressing device for transformer core production, which drives the movable sleeve to descend by pressing down the connecting rod. The descent of the movable sleeve pushes the two connecting seats closer to each other through the support rod to realize the positioning of the core material. However, the initial position of the connecting seat of the device cannot be adjusted, and only the core material of fixed width can be positioned. At the same time, since the core material is relatively soft, the edge of the core material is easily bent during positioning. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] like Figure 1 - Figure 4 As shown, a die pressing device for transformer core production comprises an equipment platform 1, a pressing platform 3 is fixedly connected to the middle part of the upper surface of the equipment platform 1, a hexagonal sliding column 2 is arranged on the rear side of the pressing platform 3, both ends of the hexagonal sliding column 2 are fixedly connected to the upper surface of the equipment platform 1, symmetrically distributed positioning mechanisms are arranged on both sides of the pressing platform 3, a spacing adjustment mechanism is arranged on the upper side of the pressing platform 3, and a die pressing mechanism is arranged in the middle of the spacing adjustment mechanism. The positioning mechanism comprises an outer sliding block 41, an outer sliding sleeve 44 is fixedly connected to the rear side of the outer sliding block 41, the outer sliding sleeve 44 is slidably connected to the hexagonal sliding column 2, a positioning block 42 is arranged on the side of the outer sliding block 41 close to the pressing platform 3, a positioning sleeve 45 is fixedly connected to the rear side of the positioning block 42, the positioning sleeve 45 is slidably connected to the hexagonal sliding column 2, a buffer spring 43 is arranged on the outside of the hexagonal sliding column 2, and both ends of the buffer spring 43 are respectively fixedly connected to the outer sliding sleeve 44 and the positioning sleeve 45, a positioning connecting rod 46 is hinged on the top of the outer sliding block 41, and a symmetrically distributed anti-curling component is arranged on the side of the positioning block 42 close to the pressing platform 3.

[0025] Under the downward pressure of the die pressing mechanism, the positioning connecting rod 46 causes the outer sliding blocks 41 to slide close to each other. The hexagonal sliding column 2 is used to slidably connect the outer sliding sleeve 44 and the positioning sliding sleeve 45. The positioning sliding sleeve 45 is used to connect the outer sliding block 41. The positioning sliding sleeve 45 is used to maintain the horizontal sliding limit of the positioning block 42. The positioning connecting rod 46 pushes the outer sliding blocks 41 to approach each other. A buffer spring 43 with elastic function is used between the outer sliding block 41 and the positioning block 42. When the positioning block 42 clamps the iron core, the outer sliding blocks 41 can continue to approach each other under the action of the connecting rod.

[0026] The anti-curling assembly includes a pressing plate 47 , the pressing plate 47 is hinged to a positioning block 42 , an electric telescopic rod 48 is hinged to the upper surface of the pressing plate 47 , and the top end of the electric telescopic rod 48 is hinged to the positioning block 42 .

[0027] The electric telescopic rod 48 is used to control the pressing plate 47 to press the iron core. Since the iron core is thin and soft, the pressing plate 47 prevents the iron core from curling when the positioning block 42 positions the iron core.

[0028] The spacing adjustment mechanism includes two threaded sleeves 51 , which are hinged at the top of the positioning link 46 , and are threadedly connected to a bidirectional threaded rod 52 . A transverse sliding column 53 is provided on the lower side of the bidirectional threaded rod 52 , and the transverse sliding column 53 is slidably connected to the threaded sleeves 51 .

[0029] The threaded connection between the threaded sleeve 51 and the bidirectional threaded rod 52 allows the bidirectional threaded rod 52 to move towards or away from each other at equal intervals when the threaded sleeve 51 rotates. The cross slide column 53 is used to slide and connect the threaded sleeve 51, maintain the sliding direction of the threaded sleeve 51, and prevent the threaded sleeve 51 from rotating excessively. The spacing between the two threaded sleeves 51 is adjusted by rotating the bidirectional threaded rod 52, and then the spacing between the two outer sliders 41 and the two positioning blocks 42 is adjusted, so that the positioning mechanism can adapt to iron cores of various widths.

[0030] The spacing adjustment mechanism further includes a threaded motor 54 , the output shaft of the threaded motor 54 is fixedly connected to one end of the bidirectional threaded rod 52 , and the bottom of the threaded motor 54 is fixedly connected to the transverse sliding column 53 .

[0031] The threaded motor 54 provides rotational power to drive the bidirectional threaded rod 52 to rotate.

[0032] The die pressing mechanism includes a lifting block 62, which is rotatably connected to the middle part of the bidirectional threaded rod 52, and the bottom end of the lifting block 62 is fixedly connected to the middle part of the horizontal sliding column 53. The bottom of the lifting block 62 is fixedly connected to the die 63, the top of the lifting block 62 is fixedly connected to the hydraulic cylinder 61, and the top end of the hydraulic cylinder 61 is fixedly connected to the horizontal plate 66.

[0033] The lifting block 62 is used to connect the hydraulic cylinder 61 and the die 63 . The die 63 is used to produce the iron core by die pressing. The cross plate 66 is used to install the hydraulic cylinder 61 .

[0034] The die pressing mechanism further includes two vertical plates 65 , the bottom ends of the vertical plates 65 are fixedly connected to the two ends of the upper surface of the equipment platform 1 , and the two ends of the horizontal sliding column 53 are fixedly connected with vertical sliders 64 , which are slidably connected to the vertical plates 65 .

[0035] The vertical plate 65 is used to connect the equipment platform 1 and the horizontal plate 66, and the vertical slider 64 is used to slide and connect the vertical plate 65 to maintain the stability of lifting.

[0036] Working principle:

[0037] The rotation power provided by the threaded motor 54 drives the rotation of the bidirectional threaded rod 52, and the rotation of the bidirectional threaded rod 52 drives the spacing adjustment of the threaded sleeve 51. The spacing adjustment of the threaded sleeve 51 controls the spacing of the initial position of the outer slider 41 to achieve the positioning of the core materials of different widths. The buffer spring 43 is used as a buffer between the positioning block 42 and the outer slider 41. When the positioning block 42 is against the core material, the outer slider 41 can continue to approach, making the clamping tighter. The hydraulic cylinder 61 controls the lifting and lowering of the lifting block 62 through its own telescopic movement. The lifting and lowering of the lifting block 62 drives the lifting and lowering of the bidirectional threaded rod 52 and the lifting and lowering of the die 63. The bidirectional threaded rod 52 makes the outer sliders 41 close to each other through the positioning connecting rod 46, and the die 63 is used for die molding.

[0038] When the positioning block 42 pushes against the core material, the electric telescopic rod 48 is started to press the pressing plate 47 downward to hold the core material, so as to prevent the edge of the core material from curling due to the clamping of the positioning block 42 .

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model.
