Description

Technical Field

[0001] The present invention relates to the technical field of ductile iron casting cutting, and specifically to an automatic cutting device for ductile iron castings. Background Art

[0002] Ductile iron is a high-strength cast iron material. Ductile iron castings refer to various components or finished products made of ductile iron materials. Due to their excellent physical and mechanical properties, such castings are widely used in many fields. In real life, there are ductile iron fasteners as shown in Figure 10 The ductile iron fastener is formed by hinging a main body part and a movable part, and the main body part is provided with a hinge hole and a positioning hole.

[0003] During the production process of the above ductile iron fasteners, it is often necessary to remove burrs and protrusions on the inner side of the ductile iron fasteners by filing, and ensure the dimensional accuracy of the ductile iron fasteners. The actual filing method for ductile iron fasteners mainly positions a single ductile iron fastener with a positioning device, and then uses an electric file to file the inner side of the ductile iron fastener so that the size of the inner side of the ductile iron fastener meets the requirements.

[0004] Although the above filing method can effectively file a single ductile iron fastener, since the shape of the inner side of the ductile iron fastener is relatively complex, and the control of the moving path of the electric file in the above filing method is mainly controlled by a computer, the moving path of the electric file under this control method cannot ensure effective filing of the inner side of the ductile iron fastener. At the same time, due to the presence of protrusions on the inner side of the ductile iron fastener, the above simple path setting cannot ensure comprehensive filing and filing effect on the inner side of the ductile iron fastener; in addition, since the positioning device can only position a single ductile iron fastener, the electric file can only file a single ductile iron fastener, and only the movement of the electric file is used for processing, resulting in low filing efficiency and poor filing effect.

Detailed implementation manners

[0030] The embodiments of the present invention will be described in detail below. The following described embodiments are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention. For those not specified in the embodiments regarding specific techniques or conditions, they shall be carried out according to the techniques or conditions described in the literature in this field or according to the product specifications.

[0031] Refer to Figures 1 - 2 , an automatic cutting device for ductile iron, including a bottom support plate 1. The top of the bottom support plate 1 is connected with a positioning platform 2 through a plurality of vertical columns 11. A cylinder 12 is installed on the top of the bottom support plate 1. A through groove is arranged in the middle of the positioning platform 2. A filing power part 3 is arranged at the pushing end of the cylinder 12, and a coordination part 4 for cooperating with the filing power part 3 is arranged at the top fixed end. A positioning part 5 is installed on the top of the positioning platform 2 and below the coordination part 4.

[0032] In the present invention, the inner wall of the ductile iron fastener after casting is comprehensively filed by the filing power part 3 cooperating with the coordination part 4, so that the inner side size of the ductile iron fastener meets the requirements. At the same time, the positioning part 5 is used to position a plurality of ductile iron fasteners at the same time, so as to ensure the filing effect of the filing power part 3 cooperating with the coordination part 4 for the ductile iron fastener. And by adopting the method of filing a plurality of ductile iron fasteners at the same time, the inner side sizes of a plurality of ductile iron fasteners can be regular and unified, and the filing efficiency can be improved.

[0033] Specifically, first, a plurality of ductile iron fasteners are positioned through the positioning part 5, and after the positioning is completed, the states of all the ductile iron fasteners are the same. Then, control the cylinder 12 to drive the filing power part 3 to reciprocate up and down, and comprehensively and effectively file along the inner side of the ductile iron fastener through the cooperation of the filing power part 3 and the coordination part 4, so that the inner side size of the ductile iron fastener after casting meets the requirements.

[0034] Refer to Figure 3 and Figure 5 , the positioning part 5 includes limiting rods 51 fixed on the front and rear sides of the through groove. A clamping component 52 for positioning the ductile iron parts is jointly connected to the two limiting rods 51; the clamping component 52 includes a vertical moving plate 521 slidably connected to the two limiting rods 51. Vertical springs are connected between the vertical moving plate 521 and the positioning platform 2 and corresponding to each limiting rod 51. An avoidance opening is arranged in the middle of the vertical moving plate 521 at the position of the through groove. A fastening structure is arranged at the front end of the top of the vertical moving plate 521; locking structures are symmetrically arranged at the front and rear positions of the top of the positioning platform 2 and corresponding to the vertical moving plate 521, and pressing structures are arranged on the top of the positioning platform 2 corresponding to the limiting rods 51.

[0035] The positioning part 5 is used to synchronously position multiple ductile iron fasteners, so that the filing power part 3 can cooperate with the coordination part 4 to file multiple ductile iron fasteners simultaneously. At the same time, the following pressing structure cooperates with the fastening structure to further fix the position of the ductile iron fasteners positioned by the limiting rod 51, so as to ensure the stability of the ductile iron fasteners during the filing process, ensure the filing effect. At the same time, through the locking structure cooperating with the vertical moving plate 521, when the filing power part 3 cooperates with the coordination part 4 to file all the ductile iron fasteners, the ductile iron fasteners can move downward briefly as the filing power part 3 moves downward, and when the filing power part 3 moves upward again, more relative displacement can be generated between the ductile iron fasteners and the filing power part 3, thereby increasing the filing effect of the filing power part 3 on the ductile iron fasteners.

[0036] Refer to Figures 3 - 5 , the fastening structure includes a mounting rod 522 fixed to the top of the vertical moving plate 521. A circular plate 523 is fixed to the top end of the mounting rod 522. A rotating sleeve 524 is rotatably mounted on the side of the mounting rod 522. A pressing plate 525 is fixed to the right rear side of the rotating sleeve 524. A positioning hole is provided at the top of the pressing plate 525. Two positioning seats 526 are fixed to the side of the circular plate 523. A coordination hole is provided on the positioning seat 526. A positioning pin is connected between the positioning hole and the corresponding coordination hole; the pressing structure includes a square column 538 fixed to the top of the positioning platform 2. A square plate is fixed to the top of the square column 538. A pressing plate 539 is sleeved on the square column 538. An avoidance hole is provided in the pressing plate 539 corresponding to the position of the limiting rod 51. A driven plate 540 is fixed to one end of the pressing plate 539 away from the avoidance hole. A rotating cooperation plate 541 is fixed to the side of the square column 538 away from the corresponding limiting rod 51. An adjusting screw 542 is rotatably mounted on the top of the rotating cooperation plate 541. The adjusting screw 542 is in threaded connection with the driven plate 540.

[0037] The fastening structure can cooperate with the pressing structure to fasten and stabilize the ductile iron fasteners, so as to ensure that the ductile iron fasteners are stably connected to the fastening structure and the vertical moving plate 521, and further enable the ductile iron fasteners to be stable in the locked state of the locking structure, and facilitate the filing power part 3 to cooperate with the coordination part 4 to effectively file the ductile iron fasteners. At the same time, the fastening structure can make the movable part inside the ductile iron fasteners stable, thereby ensuring the accuracy and effect of filing.

[0038] Specifically, first, a plurality of ductile iron fasteners are successively sleeved on two limiting rods 51. The hinge holes of the ductile iron fasteners are sleeved on the rear limiting rod 51, and the other positioning holes of the ductile iron fasteners are sleeved on the front limiting rod 51. At this time, the claw of the ductile iron fastener presses against the main body of the ductile iron fastener. Subsequently, by rotating the adjusting stud 542, the pressing plate 539 is moved downward until the pressing plate 539 presses against the top of the uppermost ductile iron fastener. After all the ductile iron fasteners are pressed tightly, the pressing plate 525 and the rotating sleeve 524 are controlled to rotate together until the pressing plate 525 presses against the claw of the ductile iron fastener and makes the claw of the ductile iron fastener firmly press on the main body of the ductile iron fastener. Then, the position of the pressing plate 525 is fixed through the positioning pin passing through the coordination hole and the positioning hole of the positioning seat 526, thereby completing the positioning of the ductile iron fastener.

[0039] Refer to Figures 5 - 7 , the locking structure includes an upper extension column 527 fixed to the top of the positioning platform 2. The upper extension column 527 is slidably penetrated by a locking column 528 and a pushed column 529 up and down respectively. An L-shaped connecting plate 530 is fixed to the top of the upper extension column 527. An elastic telescopic rod is connected between the vertical section of the L-shaped connecting plate 530 and the locking column 528. A synchronous column 531 is connected between the locking column 528 and the pushed column 529. An unlocking structure is jointly arranged between the middle part of the pushed column 529 and the longitudinal plate 411; the unlocking structure includes a longitudinal groove 532 opened in the middle part of the pushed column 529. A longitudinal moving rod 533 is slidably connected in the longitudinal groove 532. Two round holes 534 are arranged on the longitudinal moving rod 533. A yielding hole is opened on the pushed column 529. A fixing pin is connected between the yielding hole and the corresponding round hole 534. An avoidance groove is opened on the side of the pushed column 529 away from the corresponding limiting rod 51. An extension rod 535 is fixed on the side of the longitudinal moving rod 533 and at the position of the avoidance groove; an L-shaped lower extension rod 536 is fixed on the coordination part 4 at the position corresponding to the extension rod 535. A pushing block 537 is fixed on the side of the vertical section of the L-shaped lower extension rod 536 and close to the extension rod 535. A through groove is arranged on the positioning platform 2 at the positions corresponding to the pushing block 537 and the L-shaped lower extension rod 536.

[0040] The locking structure is used to limit the moving state of the vertical moving plate 521, so that the whole composed of the vertical moving plate 521 and all the ductile iron fasteners is stabilized due to the pressing of the pressing plate 539, thereby ensuring that the filing power part 3 and the coordination part 4 can effectively file the ductile iron fasteners. At the same time, when the unlocking structure unlocks the locking structure, when the filing power part 3 and the coordination part 4 file the inner side of the ductile iron fastener again, more relative displacements will be generated with the ductile iron fastener, so that the filing effect of the filing power part 3 and the coordination part 4 is better, thereby coping with the situation of more protrusions and burrs on the inner side of the ductile iron fastener after casting.

[0041] Specifically, when the pressing plate 539 is pressed to the top of the uppermost ductile iron fastener, all the ductile iron fasteners will press downward on the vertical moving plate 521, so that the vertical moving plate 521 abuts against the tops of the two locking columns 528, making the whole composed of the vertical moving plate 521 and all the ductile iron fasteners in a stable state.

[0042] When there are many burrs and protrusions on the inner side of the ductile iron fastener, first remove the fixing pin and push the longitudinal moving rod 533 towards the limiting rod 51. Then, fix the relative positions between the longitudinal moving rod 533 and the pushed column 529 again through the fixing pin. When the filing power part 3 and the coordination part 4 move downward synchronously and file the inner side of the ductile iron fastener, the pushing block 537 and the L-shaped downward extension rod 536 will first contact the extension rod 535 and push the extension rod 535 away from the limiting rod 51, so that the locking column 528 is separated from the vertical moving plate 521. Due to the frictional force on the inner side of the ductile iron fastener, the filing power part 3 and the coordination part 4 drive the ductile iron fastener, the vertical moving plate 521 and the fastening structure to move downward a certain distance together. During this process, the vertical moving plate 521 will compress the vertical spring downward, so that the vertical spring continuously has an upward pushing elastic force on the vertical moving plate 521. Then, after the ductile iron fastener, the vertical moving plate 521 and the fastening structure move downward to a certain distance, the elastic force of the vertical spring will overcome the frictional force between the filing power part 3 and the coordination part 4 and the inner side of the ductile iron fastener and drive the ductile iron fastener, the vertical moving plate 521 and the fastening structure to move upward as a whole, so that the ductile iron fastener and the filing power part 3 and the coordination part 4 generate more relative displacements, thereby increasing the filing effect of the filing power part 3 and the coordination part 4 on the inner side of the ductile iron fastener.

[0043] Refer to Figures 2 - 3 , the coordination part 4 includes a telescopic rod 41 fixed to the top fixed end. The telescopic end of the telescopic rod 41 is equipped with a longitudinal plate 411. A coordination slide rail 412 is fixed to the bottom of the longitudinal plate 411. A driven component 42 is connected to the coordination slide rail 412 through a coordination slider. A file 413 is connected between the driven component 42 and the filing power part 3; the driven component 42 includes a U-shaped frame 421 fixed to the bottom of the coordination slider. A round rod 422 is connected between the two vertical sections of the U-shaped frame 421. A horizontal sliding sleeve 423 is slidably connected to the round rod 422. A rotating rod 424 is rotatably installed at the bottom of the horizontal sliding sleeve 423. The bottom of the rotating rod 424 is connected to the top of the file 413.

[0044] The coordination part 4 is used to cooperate with the filing power part 3 to make the file 413 continuously file the inner side of the ductile iron fastener. By adopting a double-ended and stable way for the file 413, it can be closer to the grasping way in the actual use process of the file 413. Furthermore, it can not only ensure the stability of the file 413, but also ensure the filing effect of the file 413 on the inner side of the ductile iron fastener.

[0045] Refer to Figure 2 、 Figure 8 and Figure 9 , the filing power part 3 includes a mounting plate 31 fixed to the pushing end of the air cylinder 12. A longitudinal slide rail 311 is mounted on the top of the mounting plate 31. A U-shaped limiting plate 312 is connected to the longitudinal slide rail 311 through a longitudinal slider. A horizontal rod 313 is fixed between the two vertical sections of the U-shaped limiting plate 312. Connecting components 32 are symmetrically arranged on the left and right of the horizontal rod 313. A track component 33 for guiding the connecting components 32 is arranged between the mounting plate 31 and the horizontal rod 313. A front extension plate 314 is fixed to the front end of the mounting plate 31. A motor 315 is mounted on the top of the front extension plate 314 through a motor box. A threaded rod 316 is mounted on the output end of the motor 315. The threaded rod 316 is rotatably mounted at the rear end of the longitudinal slide rail 311 and is threadedly connected to the longitudinal slider.

[0046] The connecting component 32 includes a positioning slider 321 slidably connected to the horizontal rod 313. A compression spring is connected between the positioning slider 321 and the corresponding vertical end of the U-shaped limiting plate 312. A connecting rod 322 is rotatably mounted on the top of the positioning slider 321. A rotating ring 323 for cooperating with the track component 33 is rotatably mounted on the side of the connecting rod 322. The top of the connecting rod 322 is connected to the bottom of the file 413.

[0047] The filing power part 3 can not only cooperate with the coordination part 4 to drive stable reciprocating up and down motion for filing, but also drive the two files 413 to continuously file along a specified path and fit different positions of the inner side of the ductile iron fastener with the cooperation of the track component 33 and the threaded rod 316. At the same time, the connection methods of the connecting component 32 and the driven component 42 with the file 413 are both rotatably mounted. Furthermore, the file 413 can be kept in contact with the inner side of the ductile iron fastener by the correction of the track component 33, so that the rough surface of the file 413 is always in contact with the inner side of the ductile iron fastener, thus ensuring the filing effect of the file 413 on the inner side of the ductile iron fastener.

[0048] Specifically, after all the ductile iron fasteners are positioned, control the cylinder 12 to drive the mounting plate 31 to reciprocate up and down, so that the file 413 reciprocates up and down under the stable action of the double ends of the rotating rod 424 and the connecting rod 322 and continuously files the inner side of the ductile iron fastener. Subsequently, control the motor 315 to drive the threaded rod 316 to rotate, so that the connecting component 32, the file 413 and the driven component 42 move from front to back together. During this process, the rotating ring 323 is continuously pushed by the track component 33, and drives the file 413 to continuously press against the inner side of the ductile iron fastener and file the inner side of the ductile iron fastener.

[0049] It should be noted that the file 413 will be worn after long-term use, which will affect the filing effect and filing efficiency of the file 413. The file 413 needs to be replaced. In order to facilitate the replacement of the file 413, the file 413 is connected to the connecting rod 322 and the rotating rod 424 by a detachable connection method.

[0050] Refer to Figures 8 - 9 , the track component 33 includes a vertical plate 331 fixed to the rear end of the top of the mounting plate 31. The top of the vertical plate 331 is fixed with a front extension rod 332. The front end of the bottom of the front extension rod 332 is provided with a middle position sleeve 333. The left and right sides of the middle position sleeve 333 are both slidably connected with an embedded rod 334. The left end of the left embedded rod 334 is fixed with a left track plate 335. The right end of the right embedded rod 334 is fixed with a right track plate 336. The width of the left track plate 335 is greater than the width of the right track plate 336. The top of the left track plate 335 and the right track plate 336 are respectively fixed with a left upper extension plate 337 and a right upper extension plate 338. A horizontal spring is symmetrically connected front and back between the left upper extension plate 337 and the right upper extension plate 338. A pushing structure for pushing the embedded rod 334 is connected between the horizontal rod 313 and the middle position sleeve 333; the pushing structure includes a horizontal groove provided at the middle position of the bottom of the middle position sleeve 333. A fixing plate 339 is fixed at the top of the horizontal rod 313 corresponding to the horizontal groove. A plurality of trapezoidal blocks 340 are longitudinally and uniformly fixed to the top of the fixing plate 339. The relative ends of the two embedded rods 334 are both provided with a pushed slope pushed by the trapezoidal blocks 340.

[0051] The track component 33 is used to limit the movement track of the file 413, so that the file 413 can always fit against the inner side of the ductile iron fastener. At the same time, the upper left extension plate 337 and the upper right extension plate 338 can press against the non-rough surface of the file 413, so that the rough surface of the file 413 can continuously press against the inner side of the ductile iron fastener, thereby ensuring the filing effect of the file 413 on the inner side of the ductile iron fastener. At the same time, in the way of the pushing structure cooperating with the pushed slope on the embedded rod 334, it can not only increase the filing effect of the file 413 on the inner side of the ductile iron fastener, but also enable the file 413 to file more effectively the burrs and protrusions on the inner side of the ductile iron fastener, thus ensuring that the size of the ductile iron fastener after filing meets the requirements.

[0052] Specifically, when the motor 315 drives the threaded rod 316 to rotate, the U-shaped limit plate 312 and the connecting rod 322 will move from front to back. During this process, the two rotating rings 323 are respectively pushed by the left track plate 335 and the right track plate 336 to move to the left and right sides, and cooperate with the horizontal sliding sleeve 423 to drive the file 413 to move to the left and right sides and fit against the inner side of the ductile iron fastener, so as to file the inner side of the ductile iron fastener. At the same time, all the trapezoidal blocks 340 will successively push the two embedded rods 334 through the pushed slope, so that the embedded rods 334 drive the left track plate 335 and the right track plate 336 to move away from the fixed plate 339, and then push the file 413 by pushing the rotating ring 323, so that the file 413 can completely file and remove the excess ductile iron, burrs and protrusions on the inner side of the ductile iron fastener, thus ensuring that the size of the ductile iron fastener after filing meets the requirements.

[0053] The working steps of the present invention are as follows: First step, first, a plurality of ductile iron fasteners are successively sleeved on the two limit rods 51. The hinge holes of the ductile iron fasteners are sleeved on the rear limit rod 51, and the other positioning holes of the ductile iron fasteners are sleeved on the front limit rod 51. At this time, the claws of the ductile iron fasteners press against the ductile iron fastener body. Subsequently, by rotating the adjusting stud 542, the pressing plate 539 moves downward until the pressing plate 539 presses against the top of the uppermost ductile iron fastener. After all the ductile iron fasteners are pressed tightly, control the pressing plate 525 and the rotating sleeve 524 to rotate together until the pressing plate 525 presses against the claws of the ductile iron fastener and makes the claws of the ductile iron fastener firmly press on the ductile iron fastener body. Then, fix the position of the pressing plate 525 through the coordination hole and positioning hole of the positioning seat 526 by the positioning pin, thus completing the positioning of the ductile iron fastener.

[0054] In the second step, after all the ductile iron fasteners are positioned, control the air cylinder 12 to drive the mounting plate 31 to reciprocate up and down, so that the file 413 reciprocates up and down under the stable action of the double ends of the rotating rod 424 and the connecting rod 322 and continuously files the inner side of the ductile iron fastener. Subsequently, control the motor 315 to drive the threaded rod 316 to rotate, so that the connecting component 32, the file 413 and the driven component 42 move from front to back together. During this process, the rotating ring 323 is continuously pushed by the track component 33, and drives the file 413 to continuously press against the inner side of the ductile iron fastener and file the inner side of the ductile iron fastener.

[0055] In the third step, after the motor 315 drives the threaded rod 316 to rotate, the U-shaped limit plate 312 and the connecting rod 322 will move from front to back. During this process, the two rotating rings 323 are respectively pushed by the left track plate 335 and the right track plate 336 to move to the left and right sides, and cooperate with the horizontal sliding sleeve 423 to drive the file 413 to move to the left and right sides and fit against the inner side of the ductile iron fastener, so as to file the inner side of the ductile iron fastener. At the same time, all the trapezoidal blocks 340 will sequentially push the two embedded rods 334 through the pushed slopes, so that the embedded rods 334 drive the left track plate 335 and the right track plate 336 to move away from the fixed plate 339, and then push the file 413 by pushing the rotating ring 323, so that the file 413 can completely file and remove the excess ductile iron, burrs and protrusions on the inner side of the ductile iron fastener, so as to ensure that the size of the ductile iron fastener after filing meets the requirements.

[0056] In the fourth step, when there are many burrs and protrusions on the inner side of the ductile iron fastener, first remove the fixing pin, and push the longitudinal moving rod 533 towards the limiting rod 51, and then fix the relative positions between the longitudinal moving rod 533 and the pushed column 529 again through the fixing pin.

[0057] Step 5: After the positions of the longitudinal moving rod 533 and the pushed column 529 are fixed, when the filing power unit 3 and the coordination unit 4 move downward synchronously and file the inner side of the ductile iron fastener, the pushing block 537 and the L-shaped downward extension rod 536 will first contact the extension rod 535 and push the extension rod 535 in the direction away from the limiting rod 51, so that the locking column 528 is separated from the vertical moving plate 521, and the filing power unit 3 and the coordination unit 4 drive the ductile iron fastener, the vertical moving plate 521 and the fastening structure to move downward by a certain distance due to the frictional force of the inner side of the ductile iron fastener. During this process, the vertical moving plate 521 compresses the vertical spring downward, so that the vertical spring continuously has an upward pushing elastic force on the vertical moving plate 521. Then, after the ductile iron fastener, the vertical moving plate 521 and the fastening structure move downward by a certain distance, the elastic force of the vertical spring will overcome the frictional force between the filing power unit 3 and the coordination unit 4 and the inner side of the ductile iron fastener and drive the ductile iron fastener, the vertical moving plate 521 and the fastening structure to move upward as a whole, so that the ductile iron fastener and the filing power unit 3 and the coordination unit 4 generate more relative displacements, thereby increasing the filing effect of the filing power unit 3 and the coordination unit 4 on the inner side of the ductile iron fastener.

Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention, and still be covered by the protection scope of the present invention.
