Description

Technical Field

[0001] The present invention relates to the technical field of iron core manufacturing equipment, and particularly relates to a sizing tooling for sizing amorphous iron cores and an iron core sizing system. Background Art

[0002] In recent years, with the development of electronic technology towards high frequency, miniaturization, and high precision, higher and higher requirements have been put forward for the structure and performance of the iron cores of magnetic components, and it is necessary to precisely control the performance and structural dimensions of the iron cores during the manufacturing process. For C-shaped iron cores, their forming process includes two steps: annealing pre-forming and dip painting curing precision forming, and appropriate tooling and molds are required for auxiliary forming.

[0003] In the application of existing conventional technologies, manual assembly of jigs is mostly used, and further manual pressing of C-shaped iron cores is realized, resulting in technical defects such as low production capacity, difficult size control, and poor appearance consistency during production. Moreover, this application method has high requirements for personnel skills and a large human resource cost. Summary of the Invention

[0004] The purpose of the present invention is to provide a sizing tooling for sizing amorphous iron cores and an iron core sizing system to overcome the deficiencies of the prior art.

[0005] The sizing tooling for sizing amorphous iron cores includes a sizing jig and a positioning block. The sizing jig includes an outer frame, and an inner cavity for placing an iron core workpiece is formed in the outer frame. In the inner cavity, a pressing plate is cooperatively arranged at a position on one side of the outer frame, and an adjustment spacing is formed between the position of the pressing plate and the position of the outer frame with which it cooperates. When the positioning block is inserted into the adjustment spacing, both ends of the positioning block respectively abut against the pressing plate and the outer frame to apply a positioning force towards the center of the inner cavity to the pressing plate.

[0006] Further, the outer frame is enclosed by connecting the long clamping plates, short clamping plates, long connecting rods, and short connecting rods end to end. The pressing plate includes a long pressing plate and a short pressing plate. The long pressing plate is arranged on one side of the position of the long connecting rod, and the short pressing plate is arranged on one side of the position of the short connecting rod.

[0007] Further, the long pressing plate includes a long plate body arranged parallel to the long clamping plate, and a long positioning member for cooperating with the long connecting rod is connected to the side of the long plate body facing the long connecting rod.

[0008] Further, the long positioning member is in a U shape, and includes an upper extension section extending on the upper side of the long connecting rod, a lower extension section extending on the lower side of the long connecting rod, and a connecting section arranged between the long plate body and the long connecting rod. A long plate groove for inserting the long connecting rod is formed between the upper extension section, the lower extension section, and the connecting section.

[0009] Furthermore, at least two of the long positioning members are provided. On the side of the long plate body facing the long connecting rod, several adjustment spaces are formed between two adjacent long positioning members and the long connecting rod and / or between the long positioning member, the long connecting rod and the short clamping plate and / or between the long positioning member, the long connecting rod and the short connecting rod.

[0010] The present invention further includes an iron core shaping system, which includes a workbench surface. A tooling station for placing the shaping tooling as described above is provided on the workbench surface. A pressing device is provided beside the tooling station. The pressing device drives the pressing plate to move towards the center of the inner cavity, so that the iron core workpiece placed in the inner cavity forms a clamped state, and an adjustment space for accessing the positioning block is formed between the pressing plate and the position of the outer frame cooperating with it.

[0011] Furthermore, the pressing device includes a pressing drive cylinder. The drive end of the pressing drive cylinder is connected with a pressing member cooperating with the pressing plate. The pressing drive cylinder drives the pressing member to make a reciprocating driving movement towards the position of the pressing plate.

[0012] Furthermore, a flattening device is further included. The flattening device includes a flattening drive cylinder arranged above the tooling station. The drive end of the flattening drive cylinder is connected with a flattening plate parallel to the workbench surface. The flattening drive cylinder drives the flattening plate to make a reciprocating driving movement towards the tooling station.

[0013] The beneficial effects of the present invention are as follows:

[0014] Through the combined application of the iron core shaping system and the shaping tooling, while ensuring the accurate shaping dimensions and appearance consistency of the C-shaped iron core, the automatic pressing and assembling application can be effectively realized, thereby effectively improving production capacity and reducing human resource costs.

Detailed Embodiments

[0019] In order to make the technical solution, purpose and advantages of the present invention clearer and more understandable, the present invention will be further explained below in conjunction with the accompanying drawings and embodiments.

[0022] The long pressing plate 26 includes a long plate body 261 arranged parallel to the long clamping plate 21. A long positioning member 262 for cooperating with the long connecting rod 23 is connected to the side of the long plate body 261 facing the long connecting rod 23.

[0023] Two long positioning members 262 are arranged. On the side of the long plate body 261 facing the long connecting rod 23, a plurality of adjustment spaces are formed between two adjacent long positioning members 262 and the long connecting rod 23, between the long positioning member 262 and the long connecting rod 23 and the short clamping plate 22, and between the long positioning member 262 and the long connecting rod 23 and the short connecting rod 24.

[0024] The tooling station 11 is provided with a first positioning assembly on the side of the long clamping plate 21, and a first pressing device is provided on the side of the long connecting rod 23, the first pressing device includes a first pressing driving cylinder 41 provided on one side of the long connecting rod 23, the driving end of the first pressing driving cylinder 41 is connected to a first pressing member 42 matched with the long pressing plate 26, the first pressing driving cylinder 41 drives the first pressing member 42 to make a reciprocating driving motion toward the position of the long pressing plate 26, so that the first pressing member 42 can be driven to be pressed onto the long pressing plate 26 to drive the long pressing plate 26 to move toward the center of the inner cavity 25; when the first pressing device drives the long pressing plate 26 to move toward the center of the inner cavity 25, the first positioning assembly abuts against the long clamping plate 21, so that the iron core workpiece placed in the inner cavity 25 is subjected to force at both ends along the X-axis direction to form a clamping state in the X-axis direction; so that the adjustment distance between the position of the long pressing plate 26 and the long connecting rod 23 matched with it can be used to access the positioning block 3.

[0025] When the positioning block 3 is connected to the adjustment spacing, the two ends of the positioning block 3 respectively form a conflict with the long pressure plate 26 and the long connecting rod 23 to apply a first positioning force toward the center of the inner cavity 25 to the long pressure plate 26 to maintain the clamping state of the core workpiece in the X-axis direction.

[0026] Similarly, the tooling is provided with a second positioning assembly on the side of the short clamping plate 22, and the short pressure plate 27 adopts the same structure as the long pressure plate 26, and is combined with a corresponding second pressing device so that the iron core workpiece placed in the inner cavity 25 is subjected to forces at both ends along the Y-axis direction to form a clamping state in the Y-axis direction; so that the adjustment distance between the position of the short pressure plate 27 and the short connecting rod 24 it cooperates with can be used to connect the positioning block 3.

[0027] When the positioning block 3 is connected to adjust the spacing, the two ends of the positioning block 3 respectively form a conflict with the short pressure plate 27 and the short connecting rod 24 to apply a second positioning force toward the center of the inner cavity 25 to the short pressure plate 27 to maintain the clamping state of the iron core workpiece in the Y-axis direction.

[0028] Under the joint action of the first positioning force and the second positioning force, the horizontal clamping state of the core workpiece can be effectively maintained, and the clamping and positioning of the core workpiece by the shaping tooling is completed.

[0029] As a preferred embodiment, the iron core shaping system of the present invention further includes a flattening device. The flattening device includes a flattening driving cylinder 51 disposed above the tooling station 11. The driving end of the flattening driving cylinder 51 is connected to a flattening plate 52 parallel to the workbench surface 1. The flattening driving cylinder 51 drives the flattening plate 52 to make a reciprocating driving motion in the vertical direction towards the tooling station 11, so as to perform a flattening process on the iron core workpiece in the positioning fixture located on the tooling station 11 in the Z-axis direction before the final clamping state is formed, so that the positions of the iron core workpieces in the positioning fixture are on the same horizontal plane in the Z-axis direction, forming a flat state; to meet the application requirements of the shaping and pressing of the iron core workpiece.

[0030] The above are only the preferred embodiments of the present invention. For those skilled in the art of this technology, without departing from the implementation principle of the present invention, the embodiments can still be modified, and the corresponding modification schemes should also be regarded as the protection scope of the present invention.
