Description

Technical Field

[0001] This utility model relates to the technical field of transformer core lamination production equipment, specifically a special production equipment for 1200 UHV transformer core laminations. Background Technology

[0002] Silicon steel is a ferrosilicon alloy containing approximately 3% to 5% silicon, with the remainder primarily composed of iron. It is an essential soft magnetic alloy indispensable for the power, electronics, and military industries, and is also the most produced functional metallic material, mainly used as the core of various motors, generators, and transformers.

[0003] The laminations in a transformer core are a crucial component, typically hexagonal in shape. Their primary function is to enhance permeability and reduce hysteresis losses, thereby improving transformer efficiency. The shape and structure of the laminations have a significant impact on transformer performance.

[0004] The shape of the central column lamination is typically a hexagon with three pairs of parallel opposite sides. In a fully skewed transformer core without a base plate, the shape of the central column lamination is also a hexagon with three pairs of parallel opposite sides. Furthermore, the silicon steel sheet structure of the central column lamination is usually composed of several silicon steel sheets stacked layer by layer, while the silicon steel sheets of the side columns are designed as equilateral trapezoidal structures, and the V-angle of the silicon steel sheet of the central column is equal to 90 degrees.

[0005] The processing of transformer core laminations typically utilizes cross-cutting lines and CNC cross-cutting lines (core lamination machines). However, traditional silicon steel sheet cross-cutting lines and traditional core lamination machines have the following drawbacks when completing production:

[0006] 1. The longitudinal length of the feeding channel of the silicon steel sheet cross-cutting line is generally 7-8 meters. However, the feeding device is set at the starting point of the feeding channel, resulting in a long feeding distance. This causes several meters of waste material to be produced per roll of silicon steel sheet, which is a waste of materials.

[0007] 2. Completing the cutting of a single sheet requires four actions. Furthermore, there must be some overlap between these actions; otherwise, incomplete overlap can occur, resulting in scrapped products.

[0008] 3. Traditional core sheet forming machines currently on the market are only available in widths of 400mm and require three actions to complete the production of small sheets. Therefore, there is an urgent need for a special production equipment for 1200mm UHV transformer core core sheet sheets to solve the above-mentioned technical problems. Utility Model Content

[0009] The purpose of this utility model is to provide a special production equipment for the core laminations of 1200 UHV transformers, so as to solve the problems mentioned in the background art.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A special production equipment for 1200 UHV transformer core column laminations includes a feeding rack with a column installed at the bottom. One end of the feeding rack is connected to a feeding mechanism via a guiding device. A first track is provided at the left end of the feeding mechanism, and a V-shaped shear 1 is provided at the left end of the first track. A second V-shaped shear 2 is connected to the left end of the first V-shaped shear 1 via a second track. The number of second tracks is set to two, and the two second tracks are arranged symmetrically about the V-shaped shear 2.

[0012] As a preferred embodiment of this utility model, the feeding rack consists of two rotatable uncoilers, each driven by a separate electric motor.

[0013] As a preferred technical solution of this utility model, the unwinding speed of each single-head uncoiler adopts synchronous stepless speed regulation, which is adjusted synchronously with the feeding.

[0014] As a preferred embodiment of this utility model, the material guiding device is inclined.

[0015] As a preferred embodiment of this utility model, the feeding rack is located to the side and rear of the guiding device.

[0016] As a preferred embodiment of this utility model, the V-shaped scissors one and the V-shaped scissors two are arranged symmetrically about the second track.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention can produce more than 400 to 1200 central column sheet types. Production can be completed in only two actions instead of three or more. The overall longitudinal and rearward layout of the equipment is compact, which shortens the feeding distance from the feeding device to the second punching and shearing section. This effectively reduces the length of waste material left in each roll of silicon steel sheet and improves the utilization rate of materials. Attached Figure Description

[0023] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. In the embodiments of the present utility model, the different types of cross-sectional lines are not labeled according to national standards, nor do they specify material requirements for the components; they are used to distinguish the cross-sectional views of the components in the drawings.

[0024] Please see Figure 1-2 A special production equipment for 1200 UHV transformer core column laminations includes a feeding rack 1, with a column 7 installed at the bottom of the feeding rack 1. One end of the feeding rack 1 is connected to a feeding mechanism 2 via a guiding device 8. A first track 3 is provided at the left end of the feeding mechanism 2. A V-shaped shear 4 is provided at the left end of the first track 3. A second track 6 is connected to the left end of the V-shaped shear 4 via a second track 5. The number of second tracks 5 is set to two, and the two second tracks 5 are arranged symmetrically about the V-shaped shear 6.

[0025] Among them, the feeding rack 1 consists of two rotatable uncoilers, each driven by a separate electric motor.

[0026] The unwinding speed of each single-head uncoiler adopts synchronous stepless speed regulation, which is adjusted synchronously with the feeding.

[0027] Among them, the material guiding device 8 is set at an angle.

[0028] The feeding rack 1 is located to the side and rear of the guiding device 8.

[0029] Among them, V-shaped shear 1 4 and V-shaped shear 2 6 are arranged symmetrically about the second track 5. Two undulating machines that can rotate are installed on a column 7 and are driven by two motors respectively. When one end is working, the other end can be loaded with material at any time. When materials of different sizes need to be punched or pre-stacked on the production line, the two undulating machines can each be loaded with strips of different widths so that after one end cuts the first-level sheet shape, the other end can be quickly and timely switched to cut the second level.

[0030] The working principle and usage process of this utility model are as follows: First, the silicon steel coil on the feeding rack 1 enters the feeding mechanism 2 through the guiding device 8, and then enters the V-shaped shear 4 along the first track 3 for the first punching and shearing action. After punching and shearing, the silicon steel material is assistedly fed out of the V-shaped shear 6 by the lifting device, and the length of the feed is controlled by the high-precision servo system of the feeding mechanism 2. When the length requirement is reached, the V-shaped shear 6 performs the second punching and shearing operation. Then, it is sent to the receiving unit through the conveying mechanism for classification, collection and stacking, thereby completing the production task of one sheet type. Thus, it can achieve the production of more than 40 sheets. The production of medium-column sheet type from 0 to 1200 is achieved by only two actions instead of three, and the overall longitudinal and longitudinal layout of the equipment is compact, which shortens the feeding distance from the feeding device to the second punching and shearing section. This effectively reduces the length of waste material left in each roll of silicon steel sheet and improves the material utilization rate. The conveying mechanism is a transition device driven by an AC 1.5KW motor to transport the iron chip from the punching and shearing section to the receiving mechanism. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
