Description

Technical Field

[0001] This application relates to the technical field of punching sheet production equipment, and in particular to a production equipment for ultra-thin punching sheets of motor iron cores. Background Art

[0002] The motor stator core is the heart of the motor. Miniaturization, high efficiency, high power density, and high frequency and high speed are the future development trends of motors, which puts higher requirements on the electromagnetic performance of the stator core. High-performance motors require the iron loss of the motor to be as small as possible (to reduce motor heating), so it is hoped that the iron core sheets are as thin as possible (which can effectively reduce the eddy current loss of the iron core sheets) or new core materials are used. The iron core sheets are usually made of silicon steel sheets (transformer steel sheets) or ultra-thin iron-based sheets, hereinafter collectively referred to as sheet materials.

[0003] For sheet materials with a thickness greater than 0.2 mm, high-speed punching can be easily achieved, while the processing of sheet materials with a thickness less than 0.2 mm, especially ultra-thin iron-based sheet materials (0.01 - 0.15 mm), has become a major problem in realizing industrial production. In addition to being "thin", ultra-thin sheet materials also have the characteristics of being "hard" and "brittle". The ultra-thin iron-based punching sheets are too thin, resulting in high requirements for the processing accuracy of the molds. And if direct stamping is used, there will be problems such as large burrs, tearing, non-breaking, and bending, thus making batch stamping impossible.

[0004] Therefore, ultra-thin sheet processing usually adopts wire cutting for processing, and the wire cutting processing efficiency is low, so there is room for improvement. Summary of the Invention

[0023] The following is a further detailed description of this application in conjunction with the attached Figures 1 - 5 drawings.

[0024] A production device for ultra-thin punching sheets of motor iron cores, referring to Figure 1 the figure shown, includes a sheet loading section 1, a sheet gluing section 2 and a punching machine tool 3; The sheet loading section 1 is used for winding sheets. The sheets are made of silicon steel sheets (transformer steel sheets) or ultra-thin iron-based sheets. Hereinafter, the ultra-thin iron-based sheets are referred to as sheets. The thickness of the sheets is less than 0.2 mm, preferably 0.01 - 0.15 mm. In this embodiment, sheets with a thickness of 0.1 mm are used as an example to produce ultra-thin punching sheets.

[0025] At least two sheet loading sections 1 are provided. In this embodiment, three sheet loading sections 1 are provided. The multiple sheet loading sections 1 are arranged vertically. The multiple sheet loading sections 1 stack and convey multiple sheets into the punching machine tool 3 in a vertical stacking manner, that is, one sheet loading section 1 conveys one sheet, and the three sheets will be conveyed into the punching machine tool 3 in a top-middle-bottom stacking manner for punching processing.

[0026] The sheet loading section 1 includes a sheet loading roller 11, two sheet traction rollers 12 and at least two sheet guiding rollers 13. The sheet loading roller 11 is used for winding sheets. A driving motor is connected to the sheet loading roller 11, and the sheet loading roller 11 can actively wind and release the sheets. The roller surfaces of the two sheet traction rollers 12 face each other to form a sheet traction gap. The sheet passes through the sheet traction gap. A driving motor is connected to the sheet traction roller 12, and the sheet traction roller 12 can provide active traction force to traction the sheet towards the punching machine tool 3. The sheet traction roller 12 and the sheet guiding roller 13 can be made of rubber material. When the sheet traction roller 12 and the sheet guiding roller 13 contact the sheet, they can avoid damaging the sheet.

[0027] In this embodiment, two sheet guiding rollers 13 are provided. The sheet guiding rollers 13 are arranged on both sides of the sheet traction roller 12 to guide the sheet. The sheet guiding rollers 13 can be arranged to guide on the upper surface of the sheet or on the lower surface of the sheet. The setting orientation of the sheet guiding rollers 13 is determined according to the position where the sheet needs to be guided actually.

[0028] Referring Figure 1 and Figure 2 As shown, the sheet gluing part 2 is arranged between the sheet loading part 1 and the punching machine tool 3. The sheet gluing part 2 is used to coat glue on the contact surfaces of adjacent sheets. After three sheets are coated with glue, they will be stacked together. The thickness of each sheet is 0.1 mm. After three sheets are stacked, the thickness of the stacked sheets is 0.3 mm. After the sheets are coated with glue, they are fed into the punching machine tool 3 from the feeding port.

[0029] The punching machine tool 3 is used to punch a plurality of stacked sheets. The punching machine tool 3 adopts a punching machine tool 3 for 0.3 mm non-oriented silicon steel sheet. The matching die precision and the punching clearance between the upper die 31 and the lower die 32 are set according to needs. The upper die 31 is driven to lift by the punch driving mechanism 33. The punch driving mechanism 33 is a known structure and will not be introduced in detail in this embodiment.

[0030] The lower die 32 is provided with a lower die pressing mechanism for fixing the sheet in place. Before the upper die 31 presses on the lower die 32, the lower die pressing mechanism first presses on the sheet, and then the punch driving mechanism 33 closes the upper die 31 on the lower die 32, so as to facilitate the closing of the upper die 31 and the lower die 32 to punch the sheet and avoid the sheet from shifting.

[0031] After the upper die 31 and the lower die 32 are closed and punched, ultra-thin punched sheets will be cut out. The ultra-thin punched sheets will be recycled in the punching machine tool 3, and the remaining sheets after stacking and punching will be sent out from the discharging port of the punching machine tool 3.

[0032] At the discharging port of the punching machine tool 3, two sheet separating rollers 4 and several sheet collecting parts 5 are provided. The two sheet separating rollers 4 are used to separate the stacked and punched sheets. The two sheet separating rollers 4 are arranged up and down, and the two sheet separating rollers 4 are staggered in the front and back positions.

[0033] There are three sheet material receiving parts 5, and the sheet material receiving parts 5 are at different positions in the up and down height direction. The stacked sheets are separated by the sheet separation rollers 4 into three sheets, and each sheet material receiving part 5 is used to wind up one sheet after punching. The sheet material receiving part 5 includes two first sheet material receiving rollers 51, two second sheet material receiving rollers 52 and a sheet coiling roller 53. The roller surfaces of the two first sheet material receiving rollers 51 are arranged oppositely, and the sheet passes between the roller surfaces of the two first sheet material receiving rollers 51. A driving motor is connected to the first sheet material receiving roller 51, and the first sheet material receiving roller 51 can provide active traction force.

[0034] The two second sheet material receiving rollers 52 are arranged on both sides of the two first sheet material receiving rollers 51. The second sheet material receiving rollers 52 can be arranged to guide on the upper surface of the sheet or on the lower surface of the sheet. The setting orientation of the second sheet material receiving rollers 52 is determined according to the position where the sheet needs to be guided actually.

[0035] The sheet coiling roller 53 is used to wind up the sheet after punching. A driving motor is connected to the sheet coiling roller 53, and the sheet coiling roller 53 can provide the traction force for winding the sheet.

[0036] Thus, by using one sheet material receiving part 5 to traction one sheet, and then assisting the two sheet separation rollers 4 to wind up the single sheets of different layers, the purpose of separating the stacked sheets is achieved.

[0037] It should be noted that in this embodiment, the sheet loading part 1 provides the releasing force of the sheet, that is, provides the feeding force to send the sheet to one side of the punching machine tool 3. The sheet material receiving part 5 provides the traction force of the sheet, that is, the pulling force to pull the sheet out of the punching machine tool 3, so as to form a sheet feeding and traction system.

[0038] The sheet gluing part 2 can apply glue to adjacent sheets. The following is a detailed description of the sheet gluing part 2.

[0039] Refer to Figure 3 and Figure 4 As shown, the sheet gluing part 2 includes two sheet gluing rollers 21 and two sheet pressing rollers 22. Each sheet gluing roller 21 is respectively arranged between adjacent two sheets to apply glue on the sheet contact surface. The roller surfaces of the two sheet pressing rollers 22 are in contact with each other, and the two sheet pressing rollers 22 are used to press the glued sheets.

[0040] Both ends of the sheet gluing roller 21 and the sheet pressing roller 22 are rotatably installed. In one embodiment, a driving motor is connected to the sheet gluing roller 21 and the sheet pressing roller 22. By the driving motor, the rotational driving force of the sheet gluing roller 21 and the sheet pressing roller 22 is provided. The rotation of the sheet gluing roller 21 can more conveniently apply glue to the sheet, and the rotation of the sheet pressing roller 22 can provide a certain traction force to the sheet.

[0041] The sheet gluing roller 21 includes a gluing roller body 211 and rotating shaft sleeves 212 provided at both ends of the gluing roller body 211. The rotating shaft sleeves 212 are coaxially fixed to the ends of the gluing roller body 211. An installation cavity 213 is provided inside the gluing roller body 211. The gluing roller body 211 is provided with a plurality of glue outlet hole groups along its axial direction. Each glue outlet hole group includes a plurality of glue outlet holes 214 arranged along the circumferential direction of the gluing roller body 211.

[0042] Wherein, a plurality of glue outlet annular grooves 215 are provided on the inner wall of the installation cavity 213. The positions of the glue outlet annular grooves 215 correspond one by one to the glue outlet hole groups. The glue outlet annular grooves 215 are used to communicate with each glue outlet hole 214 in the glue outlet hole group. A glue outlet mechanism communicating with each glue outlet annular groove 215 is provided inside the glue outlet roller body in the installation cavity 213.

[0043] The glue outlet mechanism includes an installation bracket 216, a glue guiding pipe 217 and a plurality of glue outlet brackets 218. The installation bracket 216 extends into the installation cavity 213 from the rotating shaft sleeve 212. A plurality of glue outlet brackets 218 are located in the installation cavity 213 and fixed on the installation bracket 216. The glue outlet brackets 218 form a rotatable fit with the glue outlet annular grooves 215. The glue guiding pipe 217 is arranged along the installation bracket 216. Glue guiding branch pipes 219 are provided at the positions of each glue outlet bracket 218 on the glue guiding pipe 217. The glue guiding branch pipes 219 communicate with the glue outlet annular grooves 215.

[0044] Specifically, the glue outlet bracket 218 includes an inner bracket 2181 and an outer annular bracket 2182 connected to the inner bracket 2181. The outer annular bracket 2182 is arranged in a ring shape. The inner bracket 2181 is fixed on the installation bracket 216. The outer annular bracket 2182 is embedded in the glue outlet annular groove 215. A sealing fit is formed between the outer annular bracket 2182 and the glue outlet annular groove 215. That is, sealing annular grooves 2183 are provided on the inner walls on both sides of the glue outlet annular groove 215. Sealing annular rings 2184 embedded in the sealing annular grooves 2183 are provided on the outer walls on both sides of the outer annular bracket 2182.

[0045] A glue guiding port 220 is provided on the outer annular bracket 2182. One end of the glue guiding port 220 is communicated with the glue outlet annular groove 215. The glue guiding branch pipe 219 is connected to the other end of the glue guiding port 220. It is worth noting that the glue outlet holes 214 are arranged with large and small ends. The large end of the glue outlet hole 214 is communicated with the glue outlet annular groove 215, and the small end of the glue outlet hole 214 is communicated with the outer roller surface of the gluing roller body 211.

[0046] Thus, glue can be injected from the glue guiding port 220, and the glue overflows from the glue outlet through the glue guiding tube 217 and the glue guiding branch tube 219. With the traction of the sheet, the glue will be coated on the surface of the sheet. By arranging the sheet gluing roller 21 between two adjacent sheets, the glue can be respectively coated on the contact surfaces of the two adjacent sheets. After the sheet is coated with glue, it will enter between the two sheet pressing rollers 22, and the three sheets will be pressed together by the sheet pressing rollers 22 to form an overlapped sheet.

[0047] Among them, the glue can be glue with a relatively thin coating and suitable for metal adhesion, such as instant glue, etc. The specific type of glue can be set according to actual needs, and no specific limitation is made in this embodiment.

[0048] To make the overlapping degree of the three sheets higher, in this embodiment, referring to Figure 5 as shown, guiding baffles 6 are arranged on both sides of the sheet between the sheet gluing roller 21 and the sheet pressing roller 22. The guiding baffle 6 includes a horizontal plate 61 and a vertical plate 62, and the horizontal plate 61 and the vertical plate 62 are spliced into a T-shaped setting. The horizontal plate 61 extends along the sheet gluing roller 21 towards the sheet pressing roller 22. With the conveying of the sheet, through the setting of the guiding baffle 6, the guiding baffle 6 can slightly correct the left and right positions of the sheet, so that the edges of the three sheets enter between the two sheet pressing rollers 22 in the same plane, thereby improving the overlapping degree of the three sheets.

[0049] In this application, multiple ultra-thin iron-based sheets are glued and overlapped together and then sent into the punching machine 3 for punching. After being overlapped, the thickness of the sheets can be increased, so that the direct punching requirements of the punching machine 3 can be met, thereby effectively improving the production efficiency of punching the sheets into ultra-thin punched sheets.

[0050] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
