Description

Technical Field

[0001] This utility model belongs to the field of shearing machine technology, specifically a shearing machine structure for shearing silicon steel sheets for transformers. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, the secondary coil, and the iron core (magnetic core). Transformer silicon steel sheets are thin sheets of electrical silicon steel, which are made by hot and cold rolling and are the main material for manufacturing transformer iron cores.

[0003] Shearing silicon steel sheets is a key process in transformer core manufacturing. A common equipment is a shearing machine, suitable for cutting whole silicon steel sheets into larger plates. The operation is relatively simple and direct; the silicon steel sheet is cut to a set width or length through the relative movement of the upper and lower blades. Chinese patent application number 202421607854.1 discloses a shearing machine with an automatic plate-fixing mechanism, including a shearing machine body. The shearing machine body has a positioning mechanism inside and a shearing mechanism on its top. A scale is fixedly connected to the top of the shearing machine body. A mounting shell is fixedly connected to the right side of the shearing machine body, and a third electric push rod is fixedly connected inside the mounting shell. A push plate is fixedly connected to the left side of the third electric push rod. During use, a first electric telescopic rod can move the positioning plate without rotating the threaded rod, causing the plate to fall through the feeding channel onto the surface of the conveyor belt. The plate is then conveyed away by the conveyor belt, and the positioning plate is reset by the first electric telescopic rod, facilitating continuous shearing and greatly improving processing efficiency.

[0004] However, the above-mentioned shearing machine has the following problems in actual use: during the shearing process of silicon steel sheet, some debris will adhere to the blade edge. The accumulation of this debris will increase the burrs on the edge of the silicon steel sheet and cause greater wear to the blade.

[0005] Therefore, a shearing machine structure for shearing silicon steel sheets for transformers is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a shearing machine structure for shearing silicon steel sheets for transformers, which has the advantages of cleaning debris from the shearing blade to avoid producing more burrs on the sheet and causing more severe wear on the shearing blade.

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.

[0033] like Figures 1 to 6 As shown, this utility model provides a shearing machine structure for shearing silicon steel sheets for transformers, including a workbench 1, a fixed frame 2 fixed at the top left end of the workbench 1, a hydraulic cylinder 3 installed on the fixed frame 2, a shearing blade 4 connected to the piston rod of the hydraulic cylinder 3, and a displacement component 5 and a cleaning component 6 respectively installed on the fixed frame 2 at positions corresponding to the shearing blade 4.

[0034] The displacement component 5 includes a drive motor 501. The output end of the drive motor 501 is connected to a lead screw 502. A positioning slide rod 503 is provided on one side of the lead screw 502. A moving block 504 is connected between the lead screw 502 and the positioning slide rod 503. The lead screw 502 is threadedly connected to the moving block 504. The positioning slide rod 503 passes through the moving block 504. An L-shaped support rod 505 is fixedly connected to the moving block 504. When the shearing blade 4 stops at a position corresponding to the cleaning component 6, the wiping cotton strip 602, the high-pressure nozzle 603, and the air inlet 604 are driven to move along the blade of the shearing blade 4, so as to cooperate with the cleaning component 6 to clean the shearing blade 4.

[0035] The cleaning component 6 includes a U-shaped frame 601 fixedly connected to an L-shaped support rod 505. The U-shaped frame 601 is sequentially equipped with a wiping cotton strip 602, a high-pressure nozzle 603, and an air inlet 604. The high-pressure nozzle 603 is connected to a U-shaped tube 605, which is connected to an exhaust hose 606. One end of the exhaust hose 606 is connected to an air pump 607. The inlet of the air pump 607 is connected to a chip collection box 608 via a pipe. The chip collection box 608 is connected to an air inlet hose 609, and the end of the air inlet hose 609 is connected to the air inlet 604. The high-pressure nozzle 603 sprays high-pressure airflow to blow away debris adhering to the blade of the shearing blade 4, which is then sucked away through the air inlet 604 to prevent debris from flying around. After the airflow cleans the blade, the wiping cotton strip 602 is used for wiping to ensure cleaning effectiveness.

[0036] Specifically, support legs 7 are fixedly connected to the four corners of the bottom of the workbench 1, and cross braces are fixedly connected between adjacent support legs 7.

[0037] Furthermore, an electric telescopic rod 8 is installed at the top right end of the workbench 1. The movable rod of the electric telescopic rod 8 is connected to a pusher plate 9, which is used to push the silicon steel sheet to move in order to cut the silicon steel sheet.

[0038] Furthermore, the worktable 1 is equipped with positioning components 10 that are set in front and behind respectively;

[0039] The positioning component 10 includes an L-shaped bracket 1001 that is fixedly connected to the workbench 1. The L-shaped bracket 1001 is provided with an adjusting bolt 1002. The bottom end of the adjusting bolt 1002 is connected to a mounting bracket 1003 via a bearing. A roller 1004 is mounted on the mounting bracket 1003. The roller 1004 presses on the silicon steel sheet to limit the silicon steel sheet and does not affect the movement of the silicon steel sheet toward the shearing blade 4.

[0040] It is worth noting that a fixing ear 1005 is fixed on one side of the mounting bracket 1003, and a positioning rod 1006 is fixedly connected to the top of the fixing ear 1005. The top of the positioning rod 1006 passes through the L-shaped bracket 1001 and is used to limit the rotation of the roller 1004.

[0041] It is worth noting that a guide frame 11 is fixedly connected to the position on the workbench 1 corresponding to the shearing blade 4, which guides the cut silicon steel sheet away.

[0042] It is worth mentioning that the chip collection box 608 includes a box body 6081, and a filter screen 6082 is installed inside the box body 6081 to trap the sucked-in chips.

[0043] Hydraulic cylinder 3, drive motor 501, and air pump 607 are existing technologies and will not be described in detail. In addition, this utility model also includes power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail.

[0044] Working principle and process: The silicon steel sheet is placed on the workbench 1. The adjusting bolt 1002 of the positioning component 10 is rotated, and the mounting bracket 1003 and roller 1004 move down and press on the silicon steel sheet to limit its movement. The electric telescopic rod 8 is activated, and its extension causes the pusher plate 9 to push the silicon steel sheet towards the shearing blade 4. The hydraulic cylinder 3 is activated, and its extension allows the shearing blade 4 to cut the silicon steel sheet. When the shearing blade 4 stops at the position corresponding to the cleaning component 6, the air pump 607 of the cleaning component 6 is activated. The airflow passes through the exhaust hose 606 and U-shaped pipe 605 and is then sprayed out by the high-pressure nozzle 603. The drive motor of the displacement component 5 is activated. 501, then the lead screw 502 rotates, and under the action of the thread and positioning slide rod 503, the moving block 504 drives the L-shaped support rod 505 and the U-shaped frame 601 to move, thereby moving the wiping cotton swab 602, the high-pressure nozzle 603, and the air inlet 604 along the blade of the shearing blade 4. The high-pressure nozzle 603 sprays air to remove the debris adhering to the blade of the shearing blade 4. Then the air carrying the debris is introduced into the chip collection box 608 through the air inlet 604 and the air inlet hose 609. The debris can be intercepted by the filter screen 6082. The wiping cotton swab 602 can further wipe the blade of the shearing blade 4, and lubricating oil can be injected into the wiping cotton swab 602 to maintain the shearing blade 4.
