[0001] This utility model relates to the technical field of amorphous iron core shaping equipment, specifically an amorphous iron core shaping machine. Background Technology

[0002] In the production process of amorphous iron cores, amorphous steel strips are first wound to form iron cores of the required size. Then, the iron cores are placed in a shaping equipment and subjected to pressure and heat to solidify, thereby forming the required shape. Current shaping equipment does not have a stop structure. When the upper mold approaches the lower mold, excessive movement inevitably occurs, affecting the shaping shape of the iron core. Utility Model Content

[0003] The purpose of this invention is to provide an amorphous iron core shaping machine, which solves the problem that the upper mold moves excessively when it approaches the lower mold due to the lack of a stop structure in the existing shaping equipment, thus affecting the shaping shape of the iron core.

[0004] To solve the above problems, the present invention provides the following technical solution:

[0005] An amorphous iron core shaping machine, comprising:

[0006] Upper mold;

[0007] The lower mold is positioned parallel to and below the upper mold;

[0008] The molding device includes an upper pressure plate connected to the upper mold, a lower pressure plate connected to the lower mold, and a molding drive mechanism for driving the upper pressure plate closer to or further away from the lower pressure plate;

[0009] The heating device includes a first heating mechanism connected to the upper mold and a second heating mechanism connected to the lower mold;

[0010] The stopping device includes a first stopping module, which is disposed between the upper pressure plate and the lower pressure plate to limit the minimum distance between the upper pressure plate and the lower pressure plate.

[0011] As described above, the amorphous iron core shaping machine further includes a second stop module, which is disposed between the upper mold and the lower mold to limit the minimum distance between the upper mold and the lower mold.

[0012] In the amorphous iron core shaping machine described above, the height of the first stop module is equal to the sum of the height of the upper mold, the height of the lower mold, and the height of the second stop module.

[0013] As described above, in an amorphous iron core shaping machine, the first stop module is inserted into the lower pressure plate; the second stop module is inserted into the lower mold.

[0014] As described above, in an amorphous iron core shaping machine, the molding device further includes a connecting plate disposed below the lower pressure plate and at least two connecting columns connecting the connecting plate and the upper pressure plate. The molding drive mechanism is connected to the connecting plate and the lower pressure plate respectively, so as to drive the connecting plate to move the upper pressure plate closer to or away from the lower pressure plate.

[0015] As described above, in an amorphous iron core shaping machine, the lower pressure plate is provided with a connecting channel, the connecting post passes through the connecting channel, and one end of the connecting post is connected to the upper pressure plate, and the other end is connected to the connecting plate.

[0016] As described above, in an amorphous iron core shaping machine, the heating device further includes a temperature sensing mechanism, which is disposed on the upper mold and / or the lower mold.

[0017] As described above, in an amorphous iron core shaping machine, the first heating mechanism includes a plurality of first heating tubes arranged in parallel at intervals on the upper mold, and the second heating mechanism includes a plurality of second heating tubes arranged in parallel at intervals on the lower mold.

[0019] As described above, in an amorphous iron core shaping machine, the lower mold has limiting modules at both ends, and the limiting modules have several limiting grooves that are spaced apart and correspond one-to-one with the ends of the inner mold columns of the iron core.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1. The present invention provides an amorphous iron core shaping machine. In the iron core shaping production process, the iron core is first placed between the upper mold and the lower mold. Then, the upper pressure plate is driven by the pressure mold driving mechanism to move the upper mold closer to the lower mold to apply pressure for iron core shaping. When it moves to the limited position, the upper mold cannot continue to move under the limiting action of the first stop module. Thus, the stop device 5 effectively avoids the situation where the iron core shaping shape is affected due to excessive movement of the upper mold.

[0022] 2. The amorphous iron core shaping machine provided by this utility model has several iron core inner mold columns for connecting multiple iron cores in series. Before shaping, the iron cores are quickly connected in series on one iron core inner mold column. Then, the iron core inner mold columns connected in series are placed between the upper mold and the lower mold. There is no need to worry about the steel strip on the outer periphery of the iron core scratching the shaping mold, which greatly shortens the loading and unloading time, realizes the rapid batch shaping of iron cores, and effectively improves production efficiency.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1 to 3This embodiment provides an amorphous iron core shaping machine, including an upper mold 1, a lower mold 2, a pressing device 3, a heating device 4, and a stopping device 5. The lower mold 2 is arranged parallel to the lower part of the upper mold 1. The pressing device 3 includes an upper pressing plate 31 connected to the upper mold 1, a lower pressing plate 32 connected to the lower mold 2, and a pressing driving mechanism 33 for driving the upper pressing plate 31 closer to or further away from the lower pressing plate 32. The heating device 4 includes a first heating mechanism 41 connected to the upper mold 1 and a second heating mechanism 42 connected to the lower mold 2. The stopping device 5 includes a first stopping module 51, which is disposed between the upper pressing plate 31 and the lower pressing plate 32 to limit the minimum distance between the upper pressing plate 31 and the lower pressing plate 32.

[0031] During the iron core shaping process, the iron core is first placed between the upper mold 1 and the lower mold 2. Then, the upper pressure plate 31 is driven by the pressure mold driving mechanism 33 to move the upper mold 1 closer to the lower mold 2 to apply pressure for iron core shaping. When it moves to the limited position, the upper mold 1 cannot continue to move under the limiting action of the first stop module 51. Thus, the stop device 5 effectively avoids the situation where the iron core shaping shape is affected due to excessive movement of the upper mold 1.

[0032] Furthermore, the stopping device 5 also includes a second stopping module 52, which is disposed between the upper mold 1 and the lower mold 2 to limit the minimum distance between the upper mold 1 and the lower mold 2. While the first stopping module 51 restricts the upper pressure plate 31 from driving the upper mold 1 to continue moving downward, the second stopping module 52 directly restricts the upper mold 1 from continuing to move downward, providing a double stopping effect for better performance.

[0033] Of course, the first stop module 51 can be connected to the upper pressure plate 31 or the lower pressure plate 32. Preferably, in this embodiment, the first stop module 51 is connected to the lower pressure plate 32. Similarly, the second stop module 52 can be connected to the upper mold 1 or the lower mold 2. Preferably, in this embodiment, the second stop module 52 is connected to the lower mold 2.

[0034] Preferably, the height of the first stop module 51 is equal to the sum of the height of the upper mold 1, the height of the lower mold 2, and the height of the second stop module 52. When the upper pressure plate 31 contacts the first stop module 51, the upper mold 1 just contacts the second stop module 52.

[0035] Furthermore, the first stop module 51 is inserted into the lower pressure plate 32; the second stop module 52 is inserted into the lower mold 2. The insertion-fit structure is simple and facilitates the replacement of the first stop module 51 and the second stop module 52 of different heights to suit the shaping of iron cores with different size requirements.

[0036] Furthermore, the molding device 3 also includes a connecting plate 34 disposed below the lower pressure plate 32, and at least two connecting posts 35 connecting the connecting plate 34 and the upper pressure plate 31. The molding drive mechanism 33 is connected to the connecting plate 34 and the lower pressure plate 32 respectively, so as to drive the connecting plate 34 to move the upper pressure plate 31 closer to or away from the lower pressure plate 32. When core shaping is required, the molding drive mechanism 33 drives the connecting plate 34 to move downward relative to the lower pressure plate 32, thereby moving the upper pressure plate 31 closer to the lower pressure plate 32. When core shaping is completed, the molding drive mechanism 33 drives the connecting plate 34 to move upward relative to the lower pressure plate 32, thereby moving the upper pressure plate 31 away from the lower pressure plate 32.

[0037] Preferably, in this embodiment, the die-driving mechanism 33 is a servo electric cylinder, a modular product that integrates a servo motor with a lead screw or synchronous belt transmission mechanism to achieve high-precision, programmable linear motion. Using a servo electric cylinder allows for more precise movement of the upper pressure plate 31 and the upper die 1, helping to avoid excessive movement.

[0038] Furthermore, the lower pressure plate 32 is provided with a connecting channel 321, through which the connecting post 35 passes, with one end of the connecting post 35 connected to the upper pressure plate 31 and the other end connected to the connecting plate 34. The cooperation between the connecting post 35 and the connecting channel 321 further limits the direction of movement of the upper pressure plate 31 and the connecting plate 34 relative to the lower pressure plate 32, making the movement of the upper pressure plate 31 closer to or further away from the lower pressure plate 32 more stable.

[0039] Furthermore, the heating device 4 also includes a temperature sensing mechanism 43, which is disposed on the upper mold 1 and / or the lower mold 2. Specifically, the temperature sensing mechanism 43 may include multiple temperature sensors, which are arranged at intervals on the upper mold 1 and / or the lower mold 2. The temperature sensing mechanism 43 is electrically connected to the heating device 4. The temperature sensing mechanism 43 detects the temperature and feeds it back to the control system. The control system controls the heating device 4 according to the temperature signal to ensure that the heating temperature meets the shaping requirements.

[0040] Furthermore, the first heating mechanism 41 includes a plurality of first heating tubes arranged in parallel at intervals on the upper mold 1, and the second heating mechanism 42 includes a plurality of second heating tubes arranged in parallel at intervals on the lower mold 2. This facilitates more uniform heating in all areas between the upper mold 1 and the lower mold 2. Preferably, in this embodiment, both the first and second heating tubes are silicon carbide heating tubes. Silicon carbide heating tubes have the characteristics of high temperature resistance, oxidation resistance, corrosion resistance, rapid heating, long service life, small high-temperature deformation, and convenient installation and maintenance, and also have good chemical stability.

[0041] Furthermore, existing forming equipment generally has multiple forming modules. Before forming, the iron core needs to be carefully placed into a separate forming module, ensuring a one-to-one correspondence between the iron core and the forming module. Since the steel strip in the iron core, formed by winding steel strip, is relatively thin, it is easy to scratch the edge of the forming module during placement. Therefore, care must be taken to prevent scratches during the process of placing the iron cores into the forming modules one by one, resulting in a long loading and unloading time. This embodiment of an amorphous iron core forming machine also includes several iron core inner mold pillars 6 for connecting multiple iron cores in series. These inner mold pillars 6 are parallel to the lower mold 2 and are spaced apart between the upper mold 1 and the lower mold 2. Before forming, the iron cores are quickly connected in series on one inner mold pillar 6, and then the multiple inner mold pillars 6 connected in series are placed between the upper mold 1 and the lower mold 2. There is no need to worry about the steel strip on the outer periphery of the iron core scratching the forming mold, greatly shortening the loading and unloading time, enabling rapid batch forming of iron cores, and effectively improving production efficiency.

[0042] Furthermore, the lower mold 2 is provided with limiting modules 21 at both ends. The limiting modules 21 are provided with several spaced limiting grooves 211 that correspond one-to-one with the ends of the inner mold pillars 6 of the iron core. During loading, the ends of the multiple inner mold pillars 6 of the iron core are respectively placed into the corresponding limiting grooves 211 on both sides, which facilitates the positioning of the inner mold pillars 6 of the iron core and improves production efficiency.

[0043] It should be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information. In addition, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0044] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
