A bar forging cutting device with cleaning function

Abstract

This invention discloses a bar forging cutting device with cleaning function, including a machine body. Through the coordinated use of a limiting mechanism, a transfer mechanism, a closing mechanism, a clamping mechanism, an auxiliary mechanism, and a cutting mechanism, this invention enables the cutting of bar forgings of different lengths and outer diameters according to requirements. It also automates the process by classifying and conveying the two sets of forgings separated after cutting. Furthermore, it allows for the centralized collection and cleaning of debris generated during cutting. When cutting forgings shorter than the "dead zone," the invention fixes the rear end of the forging, while the front end abuts against two sets of fitting auxiliary plates. The top of the forging is first cut to form a "notch," and then a pressure plate enters the "notch" and engages with the outer walls of the two sets of fitting auxiliary plates, preventing the cut forging from falling off. It can also be transferred by two sets of clamping components, making the process convenient and quick.

Description

Technical Field

[0001] This invention relates to the field of cutting technology, specifically to a cutting device for bar forgings with a cleaning function. Background Technology

[0002] Bar forgings, as a very common and important type of product in the field of metal pressure processing, are rod-shaped parts with specific shapes and sizes made by plastically deforming metal billets under pressure through forging processes.

[0003] Bar forgings typically require cutting during processing. In existing technologies, to prevent debris from splashing into the external environment, the operation is usually carried out in a sealed chamber. However, even with this method, debris still splashes around inside the sealed chamber, making it inconvenient for workers to clean and collect it. Furthermore, bar forgings need to be clamped during cutting, and the contact area between the clamping device and the forging is a "dead zone." If a forging shorter than this "dead zone" needs to be cut, only one end of the forging can be fixed, causing the cut piece to fall directly into the sealed chamber, making it difficult for workers to retrieve and failing to meet their needs.

[0018] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] Example 1 Please refer to Figures 1-14 As shown, a bar forging cutting device with cleaning function includes a body 1. A feeding conveyor 101 is provided on the top left side of the body 1. The feeding conveyor 101 is used to transport the bar forging to be cut. A limiting mechanism 2 to prevent the bar forging from deviating is also installed on the feeding conveyor 101. A support plate 102 is welded to the back of the feeding conveyor 101. A blower 103 is fixedly installed at the bottom end of the support plate 102. A transfer mechanism 3 is provided on the right side of the feeding conveyor 101. A closing mechanism 4 is installed on the top front side of the body 1. A clamping mechanism 5 is installed on both the closing mechanism 4 and the support plate 102. An auxiliary mechanism 6 is provided on the front clamping mechanism 5. A cutting mechanism 7 is also installed on the closing mechanism 4.

[0020] Example 2 Please refer to Figure 2 As shown, the limiting mechanism 2 includes two sets of fixed blocks 201 fixedly installed on the front and rear sides of the top of the feeding conveyor 101. A first threaded rod 202 is rotatably installed between the two sets of fixed blocks 201. The threads at both ends of the first threaded rod 202 have opposite directions, and both ends of the outer wall of the first threaded rod 202 are threadedly connected to limiting plates 205. Both sets of limiting plates 205 are slidably connected to the first fixed rod 203. The two ends of the first fixed rod 203 are respectively welded to the inner walls of the two sets of fixed blocks 201. The outer end of the first threaded rod 202 is fixedly connected to the output end of the first servo motor 204, and the first servo motor 204 is disposed on the outer wall of one set of fixed blocks 201.

[0021] Those skilled in the art will understand that by driving the first threaded rod 202 to rotate through the output end of the first servo motor 204, the two sets of limiting plates 205 move closer or further apart, thereby changing the distance between the two sets of limiting plates 205. This distance is adapted to the length of the conveyed bar forging, thus achieving the limiting and conveying of the bar forging without positional deviation.

[0022] Example 3 Please refer to Figure 3 and Figure 4 As shown, the transfer mechanism 3 includes a first drive motor 301, a rotating frame 303, and a first stepper motor 307. The first drive motor 301 is fixedly installed on the top of the machine body 1. The rotating frame 303 is rotatably connected to the top of the machine body 1. A first driven wheel 304 is fixedly installed on the bottom of the outer wall of the rotating frame 303. A first drive wheel 302 is fixedly connected to the output end of the first drive motor 301. The first drive wheel 302 is connected to the first driven wheel 304 via a belt. The first stepper motor 307 is fixedly connected to the top of the rotating frame 303. The output end of the first stepper motor 307 extends into the rotating frame 303 and is fixedly connected to a first lead screw 305. A lifting plate 308 is threaded onto the outer wall of the first lead screw 305. The lifting plate 308 is slidably connected to a first guide rod 306. The first guide rod 306 is welded into the rotating frame 303.

[0023] Please refer to Figure 5 As shown, the transfer mechanism 3 also includes a second threaded rod 310, a second fixed rod 311, and a clamping member 313. The top of the lifting plate 308 is fixedly connected to a mounting frame 309. The second threaded rod 310 is rotatably connected inside the mounting frame 309. The second fixed rod 311 is fixedly installed inside the mounting frame 309. A second servo motor 312 that drives the second threaded rod 310 to rotate is installed on the outer wall of the mounting frame 309. Two sets of clamping members 313 are provided and are respectively threaded to both ends of the outer wall of the second threaded rod 310. The threads at both ends of the second threaded rod 310 are in opposite directions. The clamping member 313 is slidably connected to the second fixed rod 311. Two sets of feeding conveyors 104 are also provided on the top right side of the machine body 1.

[0024] Those skilled in the art will understand that the output of the second servo motor 312 drives the second threaded rod 310 to rotate, causing the two sets of clamping members 313 to move closer or further apart; the output of the first stepper motor 307 drives the first lead screw 305 to rotate, causing the lifting plate 308 to reciprocate up and down along the outer wall of the first guide rod 306, thereby driving the two sets of clamping members 313 to reciprocate up and down; and by driving the output of the first drive motor 301 to rotate, the first drive wheel 302 rotates, and under the action of the belt, the first driven wheel 304 and the rotating frame 303 rotate as a whole, thereby changing the orientation of the two sets of clamping members 313.

[0025] Example 4 Please refer to Figure 6 and Figure 7 As shown, the enclosing mechanism 4 includes a first housing 401 fixedly installed on the front side of the top of the machine body 1. The first housing 401 is located above the feeding conveyor 101. A first sliding frame 402, a second sliding frame 403, and a third sliding frame 404 are slidably connected inside the first housing 401. A first front arm 405 and a second front arm 406 are rotatably connected to the top of the first housing 401. The first front arm 405 and the second front arm 406 are rotatably connected to the front ends of the first telescopic member 409, respectively. The rear ends of the first telescopic member 409 are rotatably connected to the first rear arm 407 and the second rear arm 408, respectively. 07 and the second rear arm 408 are rotatably connected to the top of the third sliding frame 404. The first telescopic member 409 is also rotatably connected to the first sliding frame 402 and the second sliding frame 403. A multi-stage electric telescopic rod 410 is fixedly installed on the outer wall of the first housing 401. The output end of the multi-stage electric telescopic rod 410 is fixedly connected to the third sliding frame 404. A chip outlet is also provided through the bottom front side of the first housing 401. A cover plate 411 is provided on the outside of the chip outlet. The top of the cover plate 411 is fixedly installed on the output end of the first electric push rod 412. The first electric push rod 412 is fixedly installed on the front side of the first housing 401.

[0026] Those skilled in the art will understand that by controlling the output end of the multi-stage electric telescopic rod 410 to extend, the first telescopic member 409 is in an extended state, which drives the first sliding frame 402, the second sliding frame 403, and the third sliding frame 404 to move backward synchronously, and makes the rear side of the third sliding frame 404 fit against the front side of the support plate 102. A sealing structure is provided at the fitting point to prevent the debris generated by subsequent cutting from splashing into the external environment, thus protecting the environment. Conversely, by controlling the output end of the multi-stage electric telescopic rod 410 to retract, the first sliding frame 402, the second sliding frame 403, and the third sliding frame 404 move forward synchronously and reset.

[0027] Example 5 Please refer to Figure 8 and Figure 9 As shown, the clamping mechanism 5 includes a second drive wheel 503. The interior of the first housing 401 and the interior of the support plate 102 are rotatably connected to a second electric push rod 501. The output end of the second electric push rod 501 is fixedly connected to a fixing ring 505. The outer side of the first housing 401 and the outer side of the support plate 102 are also equipped with a second drive motor 502. The second drive wheel 503 is fixedly connected to the output end of the second drive motor 502. The outer wall of the second electric push rod 501 is fixedly connected to a second driven wheel 504. The second drive wheel 503 is also connected to the second driven wheel 504 via a belt.

[0028] Please refer to Figure 10 As shown, the clamping mechanism 5 also includes a clamping plate 509. A set of geared discs 506, a set of first gears 507, and several sets of second gears 508 are rotatably connected inside the fixed ring 505. The outer teeth of the geared discs 506 mesh with the first gears 507, and the inner teeth of the geared discs 506 mesh with several sets of second gears 508. Several sets of clamping plates 509 are provided, all of which are slidably connected inside the fixed ring 505. The clamping plates 509 are respectively connected with teeth that mesh with several sets of second gears 508. A motor is provided on the outer side of the fixed ring 505, and the middle part of the first gear 507 is fixedly connected to the output end of the motor.

[0029] Those skilled in the art will understand that the output of the electric motor drives the first gear 507 to rotate, causing the gear disk 506 to rotate, which in turn drives all the second gears 508 to rotate synchronously. This causes all the clamping plates 509 to move synchronously toward or away from the center of the fixed ring 505. When all the clamping plates 509 move synchronously toward the center of the fixed ring 505, the bar forging is clamped and fixed. Conversely, the bar forging is released from clamping when all the clamping plates 509 move toward the center of the fixed ring 505. Furthermore, the output of the second drive motor 502 drives the second drive wheel 503 to rotate. Under the action of the belt, the second driven wheel 504 and the second electric push rod 501 rotate as a whole, which drives the fixed ring 505 to rotate, thereby driving the bar forging in the clamped state to rotate.

[0030] Example 6 Please refer to Figure 11As shown, the auxiliary mechanism 6 includes a fixed frame 601 fixedly connected to the outer wall of the front fixed ring 505. A third threaded rod 602 is rotatably connected inside the fixed frame 601. A third fixed rod 603 is also fixedly installed inside the fixed frame 601. Two sets of auxiliary plates 605 are slidably connected to the third fixed rod 603. The two sets of auxiliary plates 605 are respectively threaded to both ends of the outer wall of the third threaded rod 602. The threads at both ends of the third threaded rod 602 have opposite directions. A third servo motor 604 that drives the third threaded rod 602 to rotate is installed on the outer wall of the fixed frame 601. A third electric push rod 606 is also installed on the outer wall of the front fixed ring 505. The output end of the third electric push rod 606 is fixedly connected to the mounting plate. A fourth electric push rod 607 is provided at the bottom of the mounting plate. A pressure plate 608 is fixedly installed at the output end of the fourth electric push rod 607.

[0031] Those skilled in the art will understand that the output of the third servo motor 604 drives the third threaded rod 602 to rotate, causing the two sets of auxiliary plates 605 to move closer or further apart. When the two sets of auxiliary plates 605 move closer together to a fitted state, the central opening of the fixing ring 505 can be blocked. Furthermore, by controlling the extension or retraction of the output of the third electric push rod 606, the pressure plate 608 can be moved to the rear or forward. In addition, by controlling the extension or retraction of the output of the fourth electric push rod 607, the pressure plate 608 can be moved upward or downward.

[0032] Example 7 Please refer to Figure 12 and Figure 13 As shown, the cutting mechanism 7 includes a first sleeve 701 fixedly installed inside the first housing 401. A second sleeve 702, a third sleeve 703, and a fourth sleeve 704 are slidably connected inside the first sleeve 701. A mounting block 711 is fixedly connected to the outer end of the fourth sleeve 704. A fifth electric push rod 712 is fixedly installed at the bottom end of the mounting block 711. A fixed seat is fixedly connected to the output end of the fifth electric push rod 712. A cutting blade 713 is rotatably connected inside the fixed seat.

[0033] Please refer to Figure 14As shown, an installation groove is provided on the inner wall of the first sleeve 701. A second stepper motor 705 is provided on the inner wall of the installation groove. The output end of the second stepper motor 705 is fixedly connected to the second lead screw 706. A lifting frame 708 is threadedly connected to the second lead screw 706. A second telescopic member 709 is rotatably connected inside the lifting frame 708. A second guide rod 707 is also fixedly connected inside the installation groove. The lifting frame 708 and the second guide rod 707 are slidably connected. One end of the second telescopic member 709 is rotatably connected to the inner wall of the first sleeve 701. The other end of the second telescopic member 709 is rotatably connected to the inner wall of the fourth sleeve 704. A sliding rod 710 is provided on the second telescopic member 709. The interiors of the second sleeve 702, the third sleeve 703, and the fourth sleeve 704 are all provided with sliding grooves that are adapted to the sliding rod 710. The sliding rod 710 is slidably connected to the sliding groove.

[0034] Those skilled in the art will understand that by rotating the second lead screw 706 through the output end of the second stepper motor 705, the lifting frame 708 moves backward along the outer wall of the second guide rod 707, and the second telescopic member 709 is in an extended state, causing the second sleeve 702, the third sleeve 703, and the fourth sleeve 704 to move backward synchronously. Conversely, if the output end of the second stepper motor 705 rotates in the opposite direction, the second sleeve 702, the third sleeve 703, and the fourth sleeve 704 will move forward synchronously. In summary, the cutting blade 713 achieves reciprocating motion. In addition, by controlling the output end of the fifth electric push rod 712 to extend or retract, the cutting blade 713 can be driven to move downward or upward.

[0035] To clearly describe the working principle of this invention, we will use... Figure 1 This is explained from a directional perspective, which refers to the "up, down, left, right, front, and back" as mentioned below, specifically as follows: S1. The distance between the two sets of limiting plates 205 is adjusted according to the length of the bar forging to be cut. The output end of the first servo motor 204 drives the first threaded rod 202 to rotate, so that the two sets of limiting plates 205 move closer or further away from each other, thereby changing the distance between the two sets of limiting plates 205. This makes the distance match the length of the bar forging being conveyed, so that the feeding conveyor 101 can limit the conveying of the bar forging without positional deviation. S2. When the bar forging reaches the right end of the feeding conveyor 101, the output end of the first stepper motor 307 drives the first lead screw 305 to rotate, causing the lifting plate 308 to move upward along the outer wall of the first guide rod 306, which in turn drives the two sets of clamping parts 313 to move upward and be located on the left and right sides of the bar forging respectively. Then, the output end of the second servo motor 312 drives the second threaded rod 310 to rotate, causing the two sets of clamping parts 313 to move closer to each other, thereby clamping and fixing the bar forging. Next, the output end of the first stepper motor 307 is driven to rotate, causing the two sets of clamping parts 313 to drive the clamped bar forging to continue to move upward, so that the center of the bar forging and the center of the front and rear fixed rings 505 are at the same height. S3. The output ends of the second electric push rods 501 on both sides are synchronously extended, so that the fixing rings 505 on the front and rear sides move closer to each other, so that the two ends of the bar forging are located inside the fixing rings 505 on the front and rear sides respectively. Then, the output ends of the motors on the outer side of the two sets of fixing rings 505 are synchronously driven to rotate synchronously, so that all the clamping plates 509 on the front and rear sides move synchronously toward the center of their respective fixing rings 505, thereby clamping and fixing the two ends of the bar forging. At this time, the two sets of clamping parts 313 release the fixing of the bar forging and reset. S4. Next, the output end of the multi-stage electric telescopic rod 410 is extended, and the first telescopic member 409 is in the extended state, which drives the first sliding frame 402, the second sliding frame 403 and the third sliding frame 404 to move backward synchronously, so that the rear side of the third sliding frame 404 fits against the front side of the support plate 102. A sealing structure is provided at the fitting point, so that the bar forging is in a closed environment composed of the first box 401, the first sliding frame 402, the second sliding frame 403, the third sliding frame 404 and the support plate 102, which prevents the debris generated by subsequent cutting from splashing into the external environment and protects the environment. S5. According to the cutting requirements of the bar forging, control the output end of the second stepper motor 705 to rotate, so that the cutting blade 713 reciprocates back and forth, driving the cutting blade 713 to the cutting position. Then, control the output end of the fifth electric push rod 712 to extend, so that the cutting blade 713 moves downward and simultaneously drives the cutting blade 713 to rotate, so as to cut at this position of the bar forging. If the diameter of the bar forging is too large during cutting, the cutting blade 713 cannot cut through the position. Then, first reset the cutting blade 713, and then drive the second drive wheel 503 to rotate through the output end of the second drive motor 502, so as to rotate the bar forging in the clamping state by 180 degrees. Continue to repeat the operation of the cutting blade 713 moving downward and rotating, so as to continue to cut the uncut part at this position, causing the bar forging to break at this position. Throughout the entire cutting process, inert gas is introduced into the sealed environment consisting of the first box 401, the first sliding frame 402, the second sliding frame 403, the third sliding frame 404, and the support plate 102 to protect the cutting area and prevent the material from oxidation, nitriding, or other chemical reactions. This also optimizes the cutting quality and efficiency. In addition, the bottom of the third sliding frame 404, the second sliding frame 403, the first sliding frame 402, and the first box 401 descends in a "stepped" manner from back to front. Therefore, a waste collection box is placed on the outside of the first box 401 at a position corresponding to the chip outlet. By opening the chip outlet and then starting the blower 103, the chips generated during cutting are blown into the waste collection box for collection, thus meeting the needs of the workers. S6. Then, by driving the output end of the second stepper motor 705 to rotate in the opposite direction, the second sleeve 702, the third sleeve 703, and the fourth sleeve 704 move forward synchronously to their reset positions. The output ends of the second electric push rods 501 on both sides retract synchronously, causing the two sets of disconnected bar forgings to move away from each other. Afterward, the two sets of clamping members 313 move again to a height position that matches the two sets of bar forgings, driving the output end of one set of second electric push rods 501 to extend, causing one set of disconnected bar forgings to be positioned between the two sets of clamping members 313. During the process, two sets of clamping members 313 clamp the forging, and under the action of the output end of the first drive motor 301, the two sets of clamping members 313 are directed toward one of the unloading conveyors 104, and the bar forging is placed on the unloading conveyor 104 for transport to the next process. The above steps are repeated to transfer the other broken bar forging to another set of unloading conveyors 104 for transport, thereby realizing automated feeding, processing and unloading, and classifying and transporting the cut bar forgings to meet the needs of the staff. S7. It is worth noting that if it is necessary to cut a forging shorter than the "dead zone" length, the outer diameter of the bar forging is analyzed first. If the outer diameter of the bar forging is smaller than the inner diameter of the opening in the middle of the fixing ring 505, the output end of the third servo motor 604 drives the third threaded rod 602 to rotate, so that the two sets of auxiliary plates 605 move closer to each other until they are in contact, thus blocking the opening in the middle of the fixing ring 505. Next, all the clamping plates 509 inside the rear fixing ring 505 clamp and fix the rear end of the bar forging. Then, the first sliding frame 402, the second sliding frame 403 and the third sliding frame 404 move backward synchronously, so that the rear side of the third sliding frame 404 is in contact with the front side of the support plate 102. The output end of the second electric push rod 501 on the front side is extended, driving the front fixing ring 505 to move backward. The movement causes the two sets of attached auxiliary plates 605 to move backward and contact the front end of the bar forging. The cutting steps are then repeated. Since the cutting blade 713 has a certain thickness, which is greater than that of the pressure plate 608, a portion of the top of the bar forging is first cut off to form a "notch". Then, the output end of the second drive motor 502 on the rear side is driven to rotate, causing the bar forging to flip so that the "notch" faces downward. Then, with the cooperation of the output ends of the third electric push rod 606 and the fourth electric push rod 607, the pressure plate 608 enters into the "notch" and cooperates with the outer wall of the two sets of attached auxiliary plates 605 to fix the front end of the bar forging. The cutting operation is then repeated to cut off the front end of the bar forging. The front end of the bar forging is also in a fixed state and will not fall off, thus meeting the needs of the workers.
