Description

Technical Field

[0001] The present invention relates to the technical field of plate cutting, in particular to a plate cutting device for transformer production and a use method thereof. Background Art

[0002] Transformers are a crucial piece of electrical equipment in power systems, primarily used to change the voltage level of alternating current. Transformers operate on the principle of electromagnetic induction, allowing them to increase (step-up transformers) or decrease (step-down transformers) the voltage without changing the frequency to accommodate varying power demands. During transformer production, stamping and cutting of the transformer housing are necessary.

[0003] However, when the existing cutting device cuts the plate, the plate is easily affected by the cutting force generated by the punching cutting, resulting in positional deviation, which leads to reduced cutting accuracy and even cutting position deviation, affecting the cutting quality. In addition, after the existing cutting device performs punching cutting, its cutter is prone to adherence to debris. After a long period of use, too much debris accumulates on the cutter, affecting the cutting dimensional accuracy and the sharpness of the cutter, and shortening the service life of the cutter.

[0051] See also Figures 5-8 The positioning assembly includes: a transmission gear 6, a moving block 7, an adjustment block 8 and a positioning block 802; a transmission gear 6 is provided inside the positioning box 5, a moving block 7 is provided inside the positioning box 5, an adjustment slot 702 is provided at the bottom of the moving block 7, an adjustment block 8 is provided inside the adjustment slot 702, a positioning block 802 is provided at the bottom of the adjustment block 8, a slot 502 is provided at the top of the positioning box 5, a slide slot 501 is provided inside the positioning box 5, a second transmission slot 504 is provided on one side of the positioning box 5, and one side of the transmission gear 6 protrudes from the positioning box 5 through the second transmission slot 504. On the outer surface of the box 5, a moving groove 503 is provided at the bottom of the positioning box 5, a transmission plate 704 is connected to one side of the moving block 7, and the transmission plate 704 is provided with teeth that mesh with the transmission gear 6, the transmission plate 704 corresponds to the position of the slot 502, and a gear plate 4011 that meshes with the transmission gear 6 is connected to one side of the lifting plate 401, an inclined surface is provided at the bottom end of the positioning block 802, a compression groove 803 is provided at the top of the positioning block 802, a compression spring 804 is connected inside the compression groove 803, and the top of the compression spring 804 is connected to the bottom of the adjustment block 8.

[0052] Among them, a fixing groove 703 is opened on the top of the moving block 7, a fixing rod 801 is connected to the top of the adjusting block 8, and a thread is provided on the outside of the fixing rod 801 and is engaged with a fixing nut, a slider 701 is connected to one side of the moving block 7, and the cross-sectional profile of the slider 701 cooperates with the cross-sectional profile of the slide groove 501, and the adjusting block 8 and the slider 701 are both T-shaped structures.

[0053] When cutting the plate, the position of the positioning block 802 can be adjusted according to the length of the plate to be cut. At this time, the fixing nut on the fixed rod 801 is removed to release the limitation of the fixed rod 801 and the adjusting block 8, and then the fixed rod 801 and the adjusting block 8 can be moved to change the position of the positioning block 802. After moving to the corresponding position, the fixing nut is re-screwed onto the fixed rod 801 to fix the fixed rod 801 in the current position, and the adjustment of the position of the positioning block 802 is completed.

[0054] By setting the sliding block 701 and the sliding groove 501, the moving direction of the moving block 7 can be limited. By setting the adjusting groove 702 and the adjusting block 8, the moving direction and distance of the positioning block 802 can be limited.

[0055] Then the lifting plate 401 moves down to drive the gear plate 4011 to move. The gear plate 4011 drives the transmission plate 704 to move through the transmission gear 6, so that the lifting plate 401 moves down, the moving block 7 drives the positioning block 802 to move up, and the positioning block 802 no longer blocks the transmission path of the plate, so as to send the plate out of the equipment box after cutting. Through the setting of the slot 502, the transmission plate 704 can provide a moving space.

[0056] Then the cutting is completed, the lifting plate 401 drives the cutter 402 and the pressing block 406 to move up, at this time the moving block 7 is driven to move down through the gear plate 4011, the transmission gear 6 and the transmission plate 704, and at the same time the moving block 7 moves down, the cut plate is transported through the electric roller 102, so that when the positioning block 802 has not moved to the lowest point, the plate has been sent below the positioning block 802, and the positioning block 802 abuts against the upper surface of the plate. Then the moving block 7 continues to move down, and at this time the adjusting block 8 continues to move down and presses the compression spring 804 through the setting of the compression slot 803 and the compression spring 804, and the positioning block 802 always abuts against the plate, on the one hand to avoid the positioning block 802 blocking the cut plate from being sent out, and on the other hand to avoid the movement interference between the adjusting block 8, the transmission plate 704 and the positioning block 802. After the plate is sent out, the positioning block 802 moves down under the action of the compression spring 804 to block the transportation path of the next plate, and plays a role in positioning the next plate.

[0057] Please refer to Figure 3 and Figure 5 In the device box 2, two hydraulic rods 4 are installed, the bottom of the hydraulic rod 4 is connected with the lifting plate 401, two fixed blocks 403 are connected at the bottom of the lifting plate 401, a movable slot 404 is formed at the bottom of the fixed block 403, two movable springs 405 are connected inside the movable slot 404, a pressing block 406 is connected at the bottom of the movable spring 405, and a pressing plate 407 is connected at the bottom of the pressing block 406.

[0058] When shearing the plate, the hydraulic rod 4 drives the lifting plate 401 to move downward, and at the same time stops the rotation of the electric roller 102, so that the cutter 402 at the bottom of the lifting plate 401 shears the plate. At the same time, the lifting plate 401 drives the fixed block 403 to move downward, and then drives the pressing block 406 and the pressing plate 407 to move downward, so that they contact the plate before the cutter 402, and as the lifting plate 401 moves downward, the pressing plate 407 and the pressing block 406 move the spring 405 under the action of the reaction force, so that the movable spring 405 generates elastic force and acts on the pressing block 406, and is transmitted to the pressing plate 407 through the pressing block 406, pressing and fixing the plate to avoid position displacement of the plate during the cutting process, which affects the cutting accuracy.

[0059] See also Figure 3 and Figure 10 , wherein, a collecting chamber 301 is provided inside the vacuum box 3, a waste box 302 is provided inside the collecting chamber 301, and the waste box 302 is made of a high-mesh filter screen; an air pump 303 is installed inside the vacuum box 3, and the suction end of the air pump 303 is communicated with the collecting chamber 301; a cutting groove 3011 is provided on the top of the vacuum box 3, and the cutting groove 3011 corresponds to the position of the cutter 402; and two opposite sides of the cutting groove 3011 are provided. An ejection groove 304 is formed on the inner wall, and an ejection plate 305 is provided inside the ejection groove 304. An ejection hole 306 is formed inside the ejection plate 305. An ejection rod 307 is passed through the ejection hole 306. One end of the ejection rod 307 is connected to an ejection block 308, and an inclined surface is provided at the end of the ejection block 308. An ejection spring 309 is connected between the ejection block 308 and the ejection plate 305, and the ejection spring 309 is located outside the ejection rod 307.

[0060] During cutting, the cutter 402 cuts into the cutting groove 3011 and squeezes the ejector block 308 open. At this time, the air inside the collection chamber 301 is extracted by the air pump 303, causing the air pressure inside the collection chamber 301 to drop, generating suction, and the dust and debris generated by the cutting are sucked into the collection chamber 301 by the suction force generated by the air pump 303 along with the air flow, and the dust, debris and impurities in the air are filtered and isolated through the waste box 302. When the ejector block 308 is squeezed open by the cutter 402, the ejector block 308 squeezes the ejector spring 309, causing the ejector spring 309 to generate elastic force and act on the ejector block 308, so that the ejector block 308 is close to the side of the cutter 402. When the cutter 402 moves up, the debris and impurities attached to the surface of the cutter 402 are scraped off by the ejector block 308, thereby ensuring the sharpness of the cutting of the cutter 402.

[0061] See also Figure 3 and Figure 4In the figure, a first transmission groove 101 is provided on the top of the workbench 1, and a plurality of evenly distributed electric rollers 102 are provided inside the first transmission groove 101. Two fixed plates 103 are connected to the top of the workbench 1, and threaded holes 104 are provided on the fixed plates 103. A threaded rod 105 is meshed and connected inside the threaded hole 104. One end of the threaded rod 105 is connected to a handwheel, and the other end of the threaded rod 105 is connected to a limit plate 106 through a bearing, and the limit plate 106 is located above the electric roller 102.

[0062] Before cutting the plate, in order to ensure that the plate can be correctly transported to the cutter 402, the position of the plate transported on the electric roller 102 can be limited by adjusting the relative distance between the two limit plates 106, and the state of the plate during transportation can be corrected. At this time, the threaded rod 105 can be driven to rotate by the handwheel, so that the threaded rod 105 drives the limit plate 106 to move under the action of the threaded hole 104, thereby completing the adjustment of the position of the limit plate 106.

[0063] Working principle:

[0064] Before cutting the plate, in order to ensure that the plate can be correctly transported to the cutter 402, the relative distance between the two limit plates 106 can be adjusted to limit the position of the plate transported on the electric roller 102, and the state of the plate during transportation can be corrected. At this time, the threaded rod 105 can be driven to rotate by the hand wheel, so that the threaded rod 105 drives the limit plate 106 to move under the action of the threaded hole 104, and the position of the limit plate 106 is adjusted. When cutting the plate, the position of the positioning block 802 can be adjusted accordingly according to the length of the plate to be cut. At this time, it can be seen that the fixing rod 801 The fixing nut is removed to release the restriction on the fixing rod 801 and the adjusting block 8. Then the fixing rod 801 and the adjusting block 8 can be moved to change the position of the positioning block 802. After moving to the corresponding position, the fixing nut is screwed onto the fixing rod 801 again, so that the fixing nut fixes the fixing rod 801 at the current position, completing the adjustment of the position of the positioning block 802. Then, through the setting of the slider 701 and the slide groove 501, the moving direction of the moving block 7 can be limited, and through the setting of the adjusting groove 702 and the adjusting block 8, the moving direction and distance of the positioning block 802 can be limited.

[0065] Then the plate is placed on the motor roller 102, sent into the equipment box 2 through the motor roller 102 until it contacts the positioning block 802, then the lifting plate 401 is driven to move down by the hydraulic rod 4, at the same time the rotation of the motor roller 102 is stopped, so that the cutter 402 at the bottom of the lifting plate 401 performs shearing operation on the plate, at the same time, the lifting plate 401 drives the fixed block 403 to move down, and then drives the pressing block 406 and the pressing plate 407 to move down, so that they contact the plate first, and with the downward movement of the lifting plate 401, the movable spring 405 is driven by the pressing plate 407 and the pressing block 406 under the action of the reaction force, so that the movable spring 405 generates elastic force and acts on the pressing block 406, and then transmits to the pressing plate 407 through the pressing block 406, so as to press and fix the plate, avoid the position deviation of the plate during cutting, affect the cutting precision, then the lifting plate 401 drives the gear plate 4011 to move, the gear plate 4011 drives the transmission plate 704 to move through the transmission gear 6, so that the moving block 7 drives the positioning block 802 to move up during the downward movement of the lifting plate 401, so that the positioning block 802 no longer blocks the transmission path of the plate, so as to send the plate out of the equipment box after cutting, and through the setting of the slot 502, the transmission plate 704 can provide movement space.

[0066] Then after cutting, the lifting plate 401 drives the cutter 402 and the pressing block 406 to move up, at this time the moving block 7 is driven to move down through the gear plate 4011, the transmission gear 6 and the transmission plate 704, and at the same time the moving block 7 moves down through the motor roller 102 to perform conveying operation on the cut plate, so that when the positioning block 802 has not moved to the lowest point, the plate has been sent below the positioning block 802, so that the positioning block 802 abuts against the upper surface of the plate, then the moving block 7 continues to move down, at this time the adjusting block 8 continues to move down and extrudes the compression spring 804 through the setting of the compression slot 803 and the compression spring 804, and the positioning block 802 always abuts above the plate, on the one hand to avoid the positioning block 802 to block the conveying path of the cut plate, on the other hand to avoid the movement interference between the adjusting block 8, the transmission plate 704 and the positioning block 802, after the plate is sent out, the positioning block 802 moves downward under the action of the elastic force of the compression spring 804, so as to block the conveying path of the next plate, and play a role in positioning the next plate.

[0067] At the same time, during cutting, the cutter 402 cuts into the cutting groove 3011 and squeezes the ejector block 308 open. At this time, the air inside the collection chamber 301 is extracted by the air pump 303, causing the air pressure inside the collection chamber 301 to drop, generating suction, and the dust and debris generated by the cutting are sucked into the collection chamber 301 by the suction force generated by the air pump 303 along with the air flow, and the dust, debris and impurities in the air are filtered and isolated through the waste box 302. When the ejector block 308 is squeezed open by the cutter 402, the ejector block 308 squeezes the ejector spring 309, causing the ejector spring 309 to generate elastic force and act on the ejector block 308, so that the ejector block 308 is close to the side of the cutter 402, and when the cutter 402 moves up, the debris and impurities attached to the surface of the cutter 402 are scraped off by the ejector block 308, thereby ensuring the sharpness of the cutting of the cutter 402.
