Description

Technical Field

[0001] The invention relates to the technical field of demagnetization machines, in particular to a mold demagnetization machine and a demagnetization method thereof. Background Art

[0002] When punching C or Cr steel, there is a friction and extrusion process of metal materials in the process of blanking, bending, drawing, etc. The metal first undergoes elastic deformation and then plastic deformation. During the friction and extrusion, the friction surface will generate heat, which will cause the surface molecules to recombine and arrange. Under the influence of the geomagnetic field, a weak magnetic field will be generated on the mold surface, and a demagnetizer is needed to demagnetize the mold.

[0003] In the existing process of demagnetizing the mold, the mold to be demagnetized is usually placed on the top of a conveyor belt, and the conveyor belt transports the demagnetized mold to the bottom of the demagnetizer, so that the demagnetizer at the top can demagnetize the mold. Since the mold has magnetism on its surface before demagnetization, the mold may absorb some metal impurities during transportation. After demagnetization, fine impurities will still adhere to the surface of the mold, and the existing demagnetizer is not provided with a relevant cleaning mechanism to clean the metal impurities.

[0004] At the same time, when the mold is demagnetized by the conveyor belt, the demagnetizer at the top demagnetizes the mold. Since the bottom end of the mold is in contact with the conveyor belt, the lower surface of the mold may not be completely demagnetized, thereby failing to completely demagnetize the mold. In view of the above problems, the present invention discloses a mold demagnetization machine and a demagnetization method thereof. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention discloses a mold demagnetization machine and a demagnetization method thereof to solve the problems raised in the above background technology.

[0011] Preferably, a guide cylinder is fixedly connected to an inner wall of one side of the top frame, the telescopic rod slides inside the guide cylinder, multiple groups of branch pipes are arranged between the dust hood and the inner wall of one side of the top frame, a connecting pipe is arranged on one side of the top frame, and multiple groups of branch pipes are connected to the connecting pipe.

[0012] Preferably, a dust suction pipe is provided between the connecting pipe and the top end of the vacuum cleaner, and a dust outlet pipe is provided between the bottom end of the vacuum cleaner and the waste box.

[0013] Preferably, a mold demagnetization method comprises:

[0014] First, place the large mold that needs to be demagnetized directly above the driving plate. Then, use the sensor to sense the position of the mold to check whether the mold body is directly above the driving plate.

[0015] Secondly, the upper surface of the mold body is demagnetized by the demagnetizer at the top. After the upper surface is demagnetized, the driving plate is driven by the cylinder to move up to the same level as the fixed block;

After cleaning the scraps on one side, the mold body can be turned over by starting the second motors on both sides, and then the control box starts the first motor again, so that the driving block drives the cleaning brush at the top to slide back and forth on the surface of the mold body to clean the scraps adhering to the other side of the mold body.

[0020] The invention can suck out the metal waste chips that have fallen on the top of the carrier plate through the dust suction mechanism, so as to keep the inside of the top frame clean. By starting the vacuum cleaner through the control box, multiple groups of dust hoods will suck the waste chips that have fallen on the top of the carrier plate into the inside of the connecting pipes through multiple groups of branch pipes, and finally enter the inside of the waste box through the dust outlet pipe for collection, thereby facilitating the cleaning of the cleaned waste chips and enabling the waste box to collect the waste chips in a centralized manner.

Embodiment 1

A cleaning mechanism 4 is arranged inside the top frame 3. The surface of the mold body 302 after demagnetization will carry some metal debris. The waste debris adhering to the surface of the mold body 302 can be scraped and cleaned by the arranged cleaning mechanism 4. The cleaning mechanism 4 includes a cleaning brush 401 for cleaning the waste debris on the surface of the mold body 302. The cleaning brush 401 slides on the surface of the mold body 302. Fixing mechanisms 5 are arranged on both sides of the mold body 302. The fixing mechanism 5 can fix the mold body 302, so as to facilitate the flipping of the fixed mold body 302, and demagnetize the other side of the mold body 302 and clean the waste debris. The fixing mechanism 5 includes a fixing block 501 for clamping the mold body 302. The fixing block 501 is used to clamp the two sides of the mold body 302. The fixed block 501 is equipped with a fixed suction cup 502 for fixing the mold body 302. The fixed suction cup 502 can fix the mold body 302, so as to avoid the situation that the two sets of fixed blocks 501 are not strong enough to clamp the mold and cause it to fall. It should be noted that the fixed block 501 is set in an L shape, and the fixed suction cup 502 is installed on the inner wall of the top of the fixed block 501 to adsorb the surface of the mold. A movable groove 7 is provided inside the carrier plate 2, and a driving plate 505 for pushing the mold body 302 is provided inside the movable groove 7. A dust suction mechanism 6 is provided on one side of the top frame 3. The dust suction mechanism 6 includes a dust collecting cover 601 arranged on one side of the inner wall of the top frame 3.

The bottom end of the dust collector 603 is provided with a waste chip box 607 for collecting waste chips.

[0033] Working principle: When in use, the mold to be demagnetized is placed directly above the driving plate 505, and the position of the mold is sensed by the sensor 506 inside the driving plate 505, and then the upper surface of the mold is demagnetized by the demagnetizer 301 at the top. After staying for a few seconds, the control box 101 controls the cylinder 507 to drive the driving plate 505 to move up, so that the driving plate 505 drives the top mold to move up to the same horizontal plane as the fixed block 501, and by starting the cylinders 507 on both sides, the two groups of fixed blocks 501 are brought close to each other to clamp the two sides of the mold body 302, and at the same time, the fixed suction cup 502 can adsorb and fix the mold body 302, and by starting the second motors 504 on both sides, the fixed mold body 302 can be driven to flip, so that the other side of the mold body 302 is flipped to the bottom end of the demagnetizer 301, and the other side of the mold body 302 can be demagnetized. Embodiment 2

[0036] A second motor 504 is installed on both sides of the top frame 3, and the output end of the second motor 504 is connected to the hydraulic cylinder 503. The output end of the second motor 504 can drive the hydraulic cylinder 503 and the fixing mechanism 5 of the output end of the hydraulic cylinder 503 to rotate together, so as to facilitate the flipping of the fixed mold body 302. The output ends of the hydraulic cylinder 503 are connected to the fixed block 501, and the fixed suction cups 502 are arranged on the top wall inside the fixed block 501.

[0037] A support frame 405 is fixedly connected to one side of the top frame 3, a screw rod 402 is arranged inside the support frame 405, a first motor 407 for driving the screw rod 402 to rotate is arranged on one side of the top frame 3, a driving block 403 is slidably arranged on the outer surface of the screw rod 402, and a slide groove 406 is opened on the top of the support frame 405.

[0038] The top of the driving block 403 is fixedly connected to a slider 404, which slides inside the slide groove 406. The top of the slider 404 is fixedly connected to one end of the cleaning brush 401, and the outer surface of the other end of the cleaning brush 401 is fixedly connected to a telescopic rod 409. When the cleaning brush 401 slides on the mold surface, the telescopic rod 409 set at the other end of the cleaning brush 401 can be driven to slide inside the guide cylinder 408. The setting of the telescopic rod 409 and the guide cylinder 408 can support the other end of the cleaning brush 401 and limit the moving trajectory of the cleaning brush 401, so that the cleaning brush 401 remains on the same horizontal plane.

[0039] A guide cylinder 408 is fixedly connected to the inner wall of one side of the top frame 3, and the telescopic rod 409 slides inside the guide cylinder 408.

A connecting pipe 604 is arranged on one side of the top frame 3, and the multiple sets of branch pipes 602 are connected to the connecting pipe 604.

[0040] Working principle: After demagnetization, the first motor 407 is started to drive the screw rod 402 to rotate, so that the screw rod 402 drives the driving block 403 to slide on the outer surface of the screw rod 402, so that the driving block 403 can drive the cleaning brush 401 at the top to slide back and forth on the lower surface of the mold body 302 to clean the debris adhered to the surface of the mold body 302. After cleaning the debris on one side, the mold body 302 can be turned over by starting the second motor 504 on both sides, and then the control box 101 starts the first motor 407 again, so that the driving block 403 drives the cleaning brush 401 at the top to slide back and forth on the surface of the mold body 302 to clean the waste debris adhered to the other side of the mold body 302.

[0043] First, the large mold to be demagnetized is placed directly above the driving plate 505. At this time, the position of the mold is sensed by the sensor 506 to check whether the mold body 302 is directly above the driving plate 505.

[0044] Secondly, the upper surface of the mold body 302 is demagnetized by the demagnetizer 301 at the top. After the upper surface is demagnetized, the driving plate 505 is driven by the cylinder 507 to move up to the same level as the fixed block 501.

[0045] Finally, the control box 101 controls the fixing mechanism 5 to clamp and fix the mold body 302, and drives the mold body 302 to rotate through the output end of the second motor 504, so that the other surface of the mold body 302 rotates to the bottom of the demagnetizer 301, so that the other surface of the mold body 302 can be demagnetized;

[0046] Working principle: After the waste chips adhering to the surface of the mold are cleaned by the cleaning mechanism 4, the waste chips will fall on the top of the carrier plate 2. The vacuum cleaner 603 is started by the control box 101, and the multiple sets of dust hoods 601 will suck the waste chips that fall on the top of the carrier plate 2 into the interior of the connecting pipe 604 through the multiple sets of branch pipes 602, and finally enter the interior of the waste box 607 through the dust outlet pipe 606 for collection, thereby facilitating the cleaning of the cleaned waste chips and enabling the waste box 607 to collect the waste chips in a centralized manner.
