Description

Technical Field

[0001] This invention relates to the field of sheet metal shearing technology, specifically a multi-functional shearing machine for processing aerospace parts. Background Technology

[0002] In existing shearing machines, the core shearing components are usually composed of upper and lower blades. By applying huge shearing forces, the material is plastically deformed and eventually separated. During high-intensity continuous operation, the blade edges are prone to failure such as chipping and cracking. In addition to the matching of strength and toughness of the blade material itself, a key factor that is often overlooked is the iron filings and debris generated during the processing.

[0003] During the shearing process, due to intense friction and compression, metal chips (iron filings) easily adhere to the cutting edge of the tool or the shearing table. These deposits not only accelerate tool wear like "abrasives," but more seriously, when hard iron filings are trapped between the tool and the sheet metal, they can instantly generate a large local stress concentration, causing microscopic or even macroscopic cracks on the tool edge, severely affecting the shearing quality and shortening the service life of expensive tools.

[0004] Furthermore, existing shearing machine cleaning systems are typically quite simple, relying mostly on external air blowing devices or simple scrapers, which are insufficient to effectively remove fine iron filings adhering to the blade surface. Even more challenging is the fact that the shearing table, as the supporting base for the lower blade, directly affects the precision of the shearing gap due to its surface finish. If protruding debris or iron filings remain on the shearing table, they will not only damage the blade edge during the downward shearing of the upper blade but may also damage the shearing table surface, creating a vicious cycle. This is especially problematic in the aerospace parts processing field, where the requirements for the flatness and burr-free edges of sheet metal are extremely high. The shortcomings of traditional equipment in cleaning and maintenance make it difficult to meet the demands of high-precision, high-cleanliness processing. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention proposes the following technical solutions:

[0006] A multi-functional shearing machine for processing aerospace parts includes a steel plate, a bed, and a top cover. The bed and the top cover are fixedly connected, and a shearing table is fixedly installed between the bed and the top cover. Multiple hydraulic cylinders are fixedly installed on the top cover, and a tool holder is fixedly installed on the moving end of each hydraulic cylinder. A shearing tool is installed on the tool holder. The shearing tool and the shearing table are tools for cutting steel plates. A fixing seat is fixed to one side of the tool holder by bolts, and the shearing tool is engaged with the fixing seat. The shearing tool is fixedly installed on the tool holder through the fixing seat.

[0007] Furthermore, a clamping device is fixedly installed on the top cover, and a main cleaner is provided on the clamping device. The main cleaner is located on one side of the shearing blade to clean the cutting edge of the shearing blade.

[0008] Furthermore, the bed is equipped with a feeder for clamping the part cut and separated from the steel plate. A secondary cleaner is provided on one side of the feeder, which moves along with the part separated from the steel plate when the feeder is in motion. The secondary cleaner is used to clean the cutting edge on one side of the shearing table.

[0009] Furthermore, the main cleaner includes a cleaning box and a sealed cylinder. The sealed cylinder is fixedly installed on the outer wall of the cleaning box. A main scraper is rotatably installed on the side of the cleaning box near the shearing blade. The main scraper is positioned on the cleaning box to scrape away debris from the surface of the shearing blade. The main scraper is made of copper alloy. A cutting torsion spring is provided between the main scraper and the cleaning box to control the adhesion force between the main scraper and the surface of the shearing blade.

[0010] Furthermore, a cleaning cylinder is provided on the side of the cleaning box near the shearing blade. The outer surface of the cleaning cylinder is covered with oil-absorbing felt. After the oil-absorbing felt adheres to the shearing blade, it forms a protective oil film on the blade surface. This not only protects the subsequent cutting effect of the shearing blade but also directly absorbs and removes fine particles from the cleaning cylinder. The cleaning cylinder is used in... Figure 6 The cleaning cylinder rotates counterclockwise, and during the rotation, the debris scraped off from the main scraper will also be adhered to the cleaning cylinder. It should be noted that when using the cleaning cylinder, it is only necessary to ensure that the cleaning cylinder is in contact with the surface of the shearing blade. This is to avoid the cleaning cylinder adhering too much oil to the surface of the shearing blade, so as to avoid excessive oil dripping.

[0011] Furthermore, the cleaning chamber is provided with a recovery chamber, an installation chamber, and a liquid storage chamber. The installation chamber is located between the recovery chamber and the liquid storage chamber. A recovery channel is provided at the entrance of the recovery chamber. The recovery channel is located below the cleaning cylinder to collect the liquid and debris dripping from the cleaning cylinder. The liquid entering the recovery channel will collect at the bottom of the recovery chamber, and the iron filings and debris at the bottom of the recovery channel can be carried by the liquid and deposited at the bottom of the recovery chamber.

[0012] Furthermore, an oil pump is installed in the recovery chamber of the cleaning box. The liquid inlet of the oil pump is located at the bottom of the recovery chamber, and the liquid outlet of the oil pump is provided with a liquid outlet pipe. The outlet of the liquid outlet pipe is located in the storage chamber. The oil pump is used to drive the liquid in the recovery chamber to be transported to the storage chamber. In a specific configuration, multiple filters are also provided at the liquid inlet of the oil pump to prevent iron filings or debris from entering the oil pump.

[0013] Furthermore, the liquid storage chamber of the cleaning tank is used to temporarily store oil. The oil in the liquid storage chamber overflows from the liquid storage chamber after reaching a predetermined height. A liquid outlet channel is provided on the side of the liquid storage chamber near the cleaning cylinder. The liquid outlet channel is used to guide the oil into the cleaning cylinder. A middle rod is fixedly installed on the moving end of the sealed cylinder. A sealing plug is fixedly installed on one end of the middle rod. The sealing plug is slidably installed in the cleaning tank to control the opening and closing of the liquid outlet channel. When the oil is blocked from entering the cleaning cylinder from the liquid storage chamber, the sealing plug blocks the liquid outlet channel to prevent the oil from flowing.

[0014] Furthermore, the mounting chamber is equipped with a compression motor, and the output shaft of the cleaning box is fixedly mounted with a compression screw. A compression block is also slidably mounted in the mounting chamber. The compression block is slidably mounted in the cleaning box and is connected to the compression screw by a thread. The compression block is used to compress a portion of the cleaning cylinder. After the compression block is driven to move by the compression screw, it can compress a portion of the cleaning cylinder located in the recycling channel, thereby removing the impurities carried on the surface of the oil-absorbing felt on the surface of the cleaning cylinder. The compression screw controls the compression force of the cleaning cylinder by controlling the moving distance of the compression block. The compression force of the compression block can also be used to control the oil on the surface of the cleaning cylinder.

[0015] Furthermore, the auxiliary cleaner includes a lifting plate and a storage box. The lifting plate is fixedly installed between the feeders and is fixedly connected to the storage box. The storage box is rotatably equipped with an auxiliary scraper, which is inclined on the storage box. The auxiliary scraper is made of copper alloy and contacts the surface of the shearing table. When the auxiliary scraper moves with the feeder, it does not clean the surface of the shearing table. However, when the auxiliary scraper returns to its initial position, it is driven by a presser to move back to the initial position. In this case, the auxiliary scraper cleans the iron filings and debris on the surface of the shearing table. The iron filings and debris cleaned and scraped off by the auxiliary scraper fall into the storage box by gravity.

[0016] Furthermore, pressing devices are provided on both sides of the cutter holder. During the cutting process, the pressing devices drive the feeder to move downward. The pressing device includes a pressing seat, an adjusting screw, and a pressing plate. Pressing seats are provided at both ends of the cutter holder. A pressing plate is slidably installed on the pressing seat. An adjusting screw is rotatably installed on the pressing plate. The adjusting screw is threadedly connected to the pressing seat. The pressing plate contacts the feeder at a predetermined time earlier than the shearing cutter contacts the steel plate, so that the feeder moves with the auxiliary cleaner and avoids direct collision between the auxiliary cleaner and the shearing cutter.

[0017] Furthermore, the feeder includes a sliding seat and an auxiliary frame. The sliding seat is slidably mounted on the bed and can contact the pressing plate on the presser. A sliding seat spring is provided between the sliding seat and the bed to allow the pressed sliding seat to return to its initial position. A slide frame is fixedly mounted on one side of the sliding seat, and multiple discharge rollers are mounted on the slide frame. An auxiliary frame is slidably mounted on the slide frame, and a telescopic spring is provided between the auxiliary frame and the slide frame.

[0018] Furthermore, the clamping device includes a positioning cylinder and a positioning slide. One end of the positioning cylinder is fixedly installed on the top cover, and the moving end of the positioning cylinder is fixedly connected to the positioning slide. A positioning seat is slidably installed on the positioning slide, and a positioning spring is provided between the positioning seat and the positioning slide.

[0019] Furthermore, multiple conveying rollers are arranged between the bed frames. The conveying rollers are driven by an external motor to move the steel plate within the device. A drive frame is fixedly installed on the top cover, and a feeding roller is slidably installed on the drive frame. The feeding roller is used to cooperate with the conveying rollers to drive the steel plate to move. A feeding roller is arranged between the feeding roller and the drive frame. During use, the steel plate is moved by the feeding roller and the conveying roller.

[0020] The beneficial effects of this invention compared to the prior art are:

[0021] (1) This device sets a main cleaner on one side of the shearing blade, so that the main cleaner can clean the iron filings and debris that may be attached to the cutting surface of the shearing blade, so as to prevent debris from adhering to the cutting edge or cutting surface of the shearing blade when cutting steel plates in the future, which would cause the shearing blade to chip and thus improve the service life of the shearing blade.

[0022] (2) This device sets up an auxiliary cleaner on one side of the shearing table, so that the auxiliary cleaner can process the shearing table at the same time, thereby avoiding the smoothness of the shearing table when it comes into contact with the shearing blade, and avoiding the damage to the shearing blade by the attachment or protrusion on the shearing table.

[0023] (3) This device sets up a cleaning cylinder in the main cleaner and sets up an oil-absorbing felt on the surface of the cleaning cylinder. The oil-absorbing felt can apply oil to the shearing blade while the cleaning cylinder can collect iron filings on the shearing blade and also collect iron filings scraped off by the main scraper.

[0036] A clamping device is fixedly installed on the top cover 102. A main cleaner 40 is provided on the clamping device. The main cleaner 40 is located on one side of the shearing blade 106 and is used to clean the cutting edge of the shearing blade 106. A feeder is provided on the bed 101. The feeder is used to clamp the part cut and separated from the steel plate 10. A secondary cleaner 50 is provided on one side of the feeder. When the feeder carries the part separated from the steel plate 10, it will move along with the secondary cleaner 50. The secondary cleaner 50 is used to clean the cutting edge on one side of the shearing table 111.

[0037] In this embodiment, an upper-cutting shearing machine is used as an example. In specific implementations, it can also be set in a lower-cutting shearing machine and a double-cutting shearing machine. When it is set in a lower-cutting shearing machine and a double-cutting shearing machine, a main cleaner 40 is set on one side of the cutting edge of the moving shearing blade. The main cleaner 40 is used to clean the adhering material on the cutting edge surface of the shearing blade.

[0038] Example 2:

[0039] This embodiment further elaborates on the structure of the tool holder 104 based on Embodiment 1, specifically as follows: Figures 2 to 4As shown, the cutter holder 104 is provided with pressers on both sides.

The cutter holder 104 is provided with press bases 107 at both ends. The press plate 109 is slidably mounted on the press base 107. The adjusting screw 108 is rotatably mounted on the press plate 109. The adjusting screw 108 is threadedly connected to the press base 107. The press plate 109 contacts the feeder at a predetermined time before the shearing cutter 106 contacts the steel plate 10, so that the feeder moves with the auxiliary cleaner 50 and avoids direct collision between the auxiliary cleaner 50 and the shearing cutter 106.

[0040] Example 3:

[0041] This embodiment further elaborates on the feeder based on Embodiment 1, specifically as follows: Figures 2 to 5 As shown, the feeder includes a sliding seat 201 and an auxiliary frame 207. The sliding seat 201 is slidably mounted on the bed 101 and can contact the pressing plate 109 on the presser. A sliding seat spring 202 is provided between the sliding seat 201 and the bed 101. The sliding seat spring 202 is used to return the pressed sliding seat 201 to its initial position. A slide frame 203 is fixedly mounted on one side of the sliding seat 201. Multiple discharge rollers 205 are mounted on the slide frame 203. The discharge rollers 205 are driven to rotate by an external motor. The rotation of the discharge rollers 205 drives the steel plate 10 to move in the feeder, and the part cut from the steel plate 10 is also discharged by the discharge rollers 205. 5. Drive and deliver the device. An auxiliary frame 207 is slidably mounted on the slide 203. A telescopic spring 204 is provided between the auxiliary frame 207 and the slide 203. The telescopic spring 204 is used to control the distance between the slide 203 and the auxiliary frame 207. An auxiliary roller 206 is provided on the auxiliary frame 207. The auxiliary roller 206 is used to cooperate with the discharge roller 205 to clamp and drive the part cut from the steel plate 10. During use, the distance between the auxiliary roller 206 and the discharge roller 205 can be automatically adapted according to the thickness of the steel plate 10. The main function of the feeder is to stabilize the side of the steel plate 10 that is being cut, and at the same time, it can also transport the part cut from the steel plate 10 to outside the device.

[0042] Example 4:

[0043] This embodiment further elaborates on the presser based on Embodiment 1, specifically as follows: Figures 2 to 5As shown, the clamping device includes a positioning cylinder 301 and a positioning slide 302. One end of the positioning cylinder 301 is fixedly installed on the top cover 102. The moving end of the positioning cylinder 301 is fixedly connected to the positioning slide 302. A positioning seat 304 is slidably installed on the positioning slide 302. A positioning spring 303 is provided between the positioning seat 304 and the positioning slide 302. The positioning seat 304 is used to press the steel plate 10 onto the shearing table 111 before shearing the steel plate 10. The movement of the positioning seat 304 is controlled by the positioning cylinder 301.

[0044] Example 5:

[0045] This embodiment further elaborates on the main cleaner 40 based on Embodiment 1, specifically as follows: Figure 2 and Figures 5 to 7 As shown, the main cleaner 40 includes a cleaning box 401 and a sealed cylinder 402. The sealed cylinder 402 is fixedly installed on the outer wall of the cleaning box 401. A main scraper 404 is rotatably mounted on the side of the cleaning box 401 near the shearing blade 106. The main scraper 404 is inclined at 30 to 45 degrees on the cleaning box 401. The side of the main scraper 404 away from the cleaning box 401 has a sharp-angled cutting edge that contacts the shearing blade 106. The inclined main scraper 404 is used to scrape away debris from the surface of the shearing blade 106. The main scraper 404 is made of copper alloy. A cutting torsion spring is provided between the main scraper 404 and the cleaning box 401. The cutting torsion spring is used to control the adhesion force between the main scraper 404 and the surface of the cutting blade 106. A cleaning cylinder 406 is also provided on the side of the cleaning box 401 near the cutting blade 106. The outer surface of the cleaning cylinder 406 is provided with oil-absorbing felt. After the oil-absorbing felt is attached to the cutting blade 106, it can form a protective oil film on the surface of the cutting blade 106. This not only protects the subsequent cutting effect of the cutting blade 106, but also directly absorbs and removes fine particles on the cleaning cylinder 406. The cleaning cylinder 406 is used in... Figure 6 The cleaning cylinder 406 rotates counterclockwise, and during the rotation of the cleaning cylinder 406, the debris scraped off from the main scraper 404 will also be adhered to the cleaning cylinder 406. It should be noted that when using the cleaning cylinder 406, it is only necessary to ensure that the cleaning cylinder 406 is in contact with the surface of the shearing blade 106. This is to avoid the cleaning cylinder 406 adhering too much oil to the surface of the shearing blade 106, so as to avoid excessive oil dripping.

[0046] During use, the auxiliary cleaner 50 moves together with the presser, so that the auxiliary cleaner 50 can move with the change of the thickness of the steel plate 10, thereby avoiding unclean parts on the surface of the shearing blade 106. During the cleaning process, when the main scraper 404 cleans the cutting edge of the shearing blade 106, because the hardness of the main scraper 404 is much lower than that of the shearing blade 106, it further avoids chipping.

[0047] Example 6:

[0048] This embodiment further elaborates on the internal structure of the cleaning box 401 based on Embodiment 1, specifically as follows: Figures 5 to 7 As shown, the cleaning box 401 is provided with a recycling chamber, an installation chamber, and a liquid storage chamber. The installation chamber is located between the recycling chamber and the liquid storage chamber. A recycling channel 4012 is provided at the entrance of the recycling chamber. The recycling channel 4012 is located below the cleaning cylinder 406 to collect the liquid and debris dripping from the cleaning cylinder 406. The liquid entering the recycling channel 4012 will collect at the bottom of the recycling chamber, and the iron filings and debris at the bottom of the recycling channel 4012 can be carried by the liquid and deposited at the bottom of the recycling chamber.

[0049] The cleaning box 401 is equipped with an oil pump 410 in its recovery chamber. The liquid inlet of the oil pump 410 is located at the bottom of the recovery chamber, and the liquid outlet of the oil pump 410 is equipped with an outlet pipe 411. The outlet of the outlet pipe 411 is located in the storage chamber. The oil pump 410 is used to drive the liquid in the recovery chamber to be transported to the storage chamber. In a specific configuration, multiple filters are also provided at the liquid inlet of the oil pump 410 to prevent iron filings or debris from entering the oil pump 410.

[0050] The liquid storage chamber of the cleaning tank 401 is used to temporarily store oil. The oil in the liquid storage chamber overflows from the liquid storage chamber after reaching a predetermined height. A liquid outlet channel 4011 is provided on the side of the liquid storage chamber near the cleaning cylinder 406. The liquid outlet channel 4011 is used to guide the oil into the cleaning cylinder 406. An intermediate rod 403 is fixedly installed on the moving end of the sealing cylinder 402. A sealing plug 405 is fixedly installed on one end of the intermediate rod 403. The sealing plug 405 is slidably installed in the cleaning tank 401 to control the opening and closing of the liquid outlet channel 4011. When the oil is blocked from entering the cleaning cylinder 406 from the liquid storage chamber, the sealing plug 405 blocks the liquid outlet channel 4011 to prevent the oil from flowing.

[0051] The installation chamber is equipped with a compression motor 409, which is fixedly installed on the inner wall of the cleaning box 401. A compression screw 408 is fixedly installed on the output shaft of the cleaning box 401. A compression block 407 is also slidably installed in the installation chamber. The compression block 407 is slidably installed in the cleaning box 401. The compression block 407 is used to compress a part of the cleaning cylinder 406. After being driven to move by the compression screw 408, the compression block 407 can compress a part of the cleaning cylinder 406 located in the recycling channel 4012, thereby removing the impurities carried on the surface of the oil-absorbing felt on the surface of the cleaning cylinder 406. The compression screw 408 controls the compression force of the cleaning cylinder 406 by controlling the moving distance of the compression block 407. The compression force of the compression block 407 can also be used to control the oil on the surface of the cleaning cylinder 406.

[0052] Example 7:

[0053] This embodiment further elaborates on the auxiliary cleaner 50 based on Embodiment 1, as follows: Figures 5 to 7 As shown, the auxiliary cleaner 50 includes a lifting plate 501 and a storage box 502. The lifting plate 501 is fixedly installed between the feeders and is fixedly connected to the storage box 502. The storage box 502 is rotatably mounted with an auxiliary scraper 503. The auxiliary scraper 503 is inclined on the storage box 502 and is made of copper alloy. The auxiliary scraper 503 contacts the surface of the shearing table 111. When the auxiliary scraper 503 moves with the feeder, it does not clean the surface of the shearing table 111. When the auxiliary scraper 503 returns to its initial position, it will be driven by a presser to move back to its initial position. In this case, the auxiliary scraper 503 will clean the iron filings and debris on the surface of the shearing table 111. The iron filings and debris cleaned and scraped off by the auxiliary scraper 503 will fall into the storage box 502 by gravity.

[0054] Working principle:

[0055] In operation, the steel plate 10 is conveyed to the area below the shearing blade 106 via the conveying roller 110 and the feeding roller 114. After passing the shearing blade 106, one end of the steel plate 10 is clamped by the feeder. Once the steel plate 10 has passed the shearing blade 106 a predetermined distance, the drive to the steel plate 10 is stopped. Furthermore, by using a hydraulically driven positioning cylinder 301 in the clamping device, the clamping device, in conjunction with the shearing table 111, locks the position of the steel plate 10. At this point, the device is... Figure 1 and Figure 2In the state shown, the shearing cutter 106 can be driven to cut the steel plate 10. The shearing cutter 106 is moved by the hydraulic cylinder 103. During the movement of the shearing cutter 106, the presser first contacts the shearing cutter 106 with the steel plate 10 and then with the feeder. The presser contacts the feeder to allow the feeder and the auxiliary cleaner 50 to move, preventing the auxiliary scraper 503 in the auxiliary cleaner 50 from interfering with the cutting action of the shearing cutter 106. After the feeder moves, if it is located on one side inside the feeder, the extension spring 204 can be stretched by compression to avoid being affected. Meanwhile, the shearing cutter... After the cutting blade 106 completes the cutting, it returns to its initial position. During this process, the auxiliary cleaner 50 cleans one side of the cutting blade 106 and the surface of the shearing table 111. The portion cut from the steel plate 10 is then transported outside the device by the feeder. This simultaneous scraping cleaning by the main cleaner 40 and the auxiliary cleaner 50 ensures that the cutting blade 106 will not chip due to foreign matter adhering to it during the cutting operation on the shearing table 111, thereby improving the durability of the cutting blade 106.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
