Description

Technical Field

[0001] The present invention belongs to the technical field of transformer iron core stamping, and more specifically, particularly relates to a transformer laminated iron core manufacturing device and a manufacturing method thereof. Background Art

[0002] The transformer core is the main magnetic circuit part of the transformer. The core and the coil wound on it form a complete electromagnetic induction system. The power transmitted by the transformer depends on the material and cross-sectional area of ​​the core. Stamping equipment is required in the production of the transformer core.

[0003] The transformer core stamping equipment currently in use has the following problems: 1. When the metal sheet to be stamped is not accurately placed in the stamping position, the stamping head will move downward, causing the stamped transformer core to not meet production requirements and resulting in a waste of metal sheet raw materials; 2. The workers' hands cannot be fully moved to a safe area before stamping, causing accidental injuries to the workers' hands during stamping; 3. It cannot automatically remind workers to clean up the stamping waste. When there is too much stamping waste, it increases the difficulty of cleaning for the workers.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. In the present invention, when the metal sheet to be manufactured is accurately placed in the groove at the top of the support base, the metal sheet presses the four metal movable blocks, so that the four metal movable blocks are automatically connected under the action of the metal sheet. At this time, the staff can start the electric cylinder through the control button, and the electric cylinder drives the iron core manufacturing head to move downward automatically, and then automatically resets after the stamping is completed; when the metal sheet to be manufactured is not accurately placed in the groove at the top of the support base, the metal sheet cannot contact the four metal movable blocks. At this time, the staff cannot start the electric cylinder through the control button, which ensures that the stamped metal sheet meets the production accuracy;

[0025] In addition, when the staff presses the control button, one hand of the staff needs to pull the U-shaped handle and the other hand presses the control button, ensuring that both hands of the staff are in a safe area when pressing the control button, avoiding accidental injury to the staff's hands. When the staff releases the U-shaped handle, the rectangular baffle automatically resets under the action of two reset springs four, making it convenient for next use.

[0026] 2. The present invention collects the metal waste after stamping, which is convenient for the staff to centrally process the stamping waste. The arrangement of the four positioning balls plays an elastic positioning role on the collection frame, making the collection frame more stable after installation. When the staff pulls the two cleaning handles, the four supporting springs are compressed, so that the four positioning balls are automatically stored in the four dovetail connecting plates, which facilitates the installation and disassembly of the collection frame.

[0027] In addition, when the push switch is in the pressed state, the alarm works, which is convenient for reminding the staff to clean up the stamping waste and facilitating the staff to appropriately adjust the installation position of the push switch according to their own situation. When the push switch is installed on the highest hollow mounting tube, the collected weight of the stamping waste is the lightest. When the push switch is installed on the lowest hollow mounting tube, the collected weight of the stamping waste is the heaviest. While ensuring that the weight can be borne by itself, the number of times the stamping waste is cleaned is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the staff cannot start the electric cylinder 204 through the control button 402, which ensures that the stamped metal sheet meets the production accuracy and avoids the waste of metal sheet raw materials;

[0054] Because the control button 402 is fixedly installed inside the shell 401, and the rectangular baffle 403 is slidably installed on the shell 401, when the staff presses the control button 402, one hand of the staff needs to pull the U-shaped handle 404, and the other hand of the staff presses the control button 402, which ensures that when pressing the control button 402, both hands of the staff are in a safe area, avoiding accidental injury to the hands of the staff.

[0056] In addition, the voltage in the four wires is less than 36V, and the current in the four wires is less than 10mA.

[0057] In the present disclosure, Figures 4 to 7 As shown, the collecting unit 3 includes: a collecting frame 301, a rectangular mounting plate 302 and a cleaning handle 303; the collecting frame 301 is slidably mounted on the four dovetail connecting plates 102, and the left and right sides of the collecting frame 301 are in contact with the four positioning balls 103, and the bottom of the collecting frame 301 is flush with the bottom of the supporting base 101; the rectangular mounting plate 302 is welded to the inside of the collecting frame 301; there are two cleaning handles 303, and the two cleaning handles 303 are welded to the left and right sides of the collecting frame 301; the collecting unit 3 also includes: a circular guide rod 304, a waste support plate 305 and a limiting snap ring 306; there are two circular guide rods 304, and the two circular guide rods 304 are welded to the top of the rectangular mounting plate 302; the waste support plate 305 is slidably mounted on the outside of the two circular guide rods 304; there are two limiting snap rings 306, and the two limiting snap rings 306 are welded to the top of the two circular guide rods 304;

[0058] The collecting unit 3 further includes: a supporting spring 307, a hollow mounting tube 308 and an adjusting connector 309; there are two supporting springs 307, and the two supporting springs 307 are installed outside the two circular guide rods 2 304, and the two supporting springs 307 are located between the rectangular mounting plate 302 and the waste supporting plate 305; there are five hollow mounting tubes 308, and the five hollow mounting tubes 308 are welded on the top of the rectangular mounting plate 302, and the five hollow mounting tubes 308 have different heights; the adjusting connector 309 is inserted into the middle hollow mounting tube 308, The outer wall of the adjusting connector 309 is provided with a circle of anti-slip grooves 3091; the collecting unit 3 further comprises: a battery 310, an alarm 311 and a push switch 312; the battery 310 is fixedly mounted on the top of the rectangular mounting plate 302; the alarm 311 is fixedly mounted on the top of the rectangular mounting plate 302, and the battery 310 is electrically connected to the alarm 311; the push switch 312 is fixedly mounted inside the adjusting connector 309, and the push switch 312 is electrically connected to the battery 310 and the alarm 311, and the alarm 311 works when the push switch 312 is in a pressed state;
