Description

Technical Field

[0001] This invention relates to the field of metal sheet cutting technology, and in particular to a fixed-length cutting device for thick nickel sheets. Background Technology

[0002] In the fixed-length cutting of thick nickel plates, traditional cutting devices usually require an additional independent conveying mechanism to feed the plates. This conveying mechanism and the cutting unit are controlled independently, which not only leads to a complex overall structure and a large footprint, but also easily causes the two to be out of sync, resulting in cumulative deviations in the feeding length and ultimately affecting the accuracy of fixed-length cutting. At the same time, thick nickel plates are prone to generating metal shavings during the cutting process. These shavings will scatter and adhere to the cutting table (14) surface, making daily cleaning very inconvenient. Long-term accumulation of shavings can easily scratch the surface of the nickel plate and interfere with the positioning and support during subsequent cutting, further reducing the cutting quality and processing accuracy. Therefore, existing cutting devices have problems such as poor coordination between conveying and cutting, difficulty in cleaning shavings, and impact on accuracy. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a nickel thick plate fixed-length cutting device. By designing the conveying mechanism and the cutting device to work in tandem, the nickel thick plate can be automatically conveyed forward to a specified length after each cutting, preparing it for the next cutting. This eliminates the need for an additional independent conveying control system, ensuring the coordination and accuracy of continuous fixed-length cutting, improving production efficiency, and effectively solving the problems mentioned in the background art.

[0004] The technical solution adopted by the present invention to solve the above problems is as follows: A nickel plate cutting device for fixed length includes a base plate, a support platform and an operating platform at the upper end of the base plate, a cutting platform at the upper end of the support platform, a drive plate that can move up and down at the upper end of the support platform, a cutting blade at the lower end of the drive plate, and a pressure plate at the lower end of the drive plate. A nickel plate is placed on the upper end of the operating platform, and conveying mechanisms are provided on both sides of the operating platform. Each conveying mechanism includes a one-way clamp. When the drive plate moves downward, the pressure plate can first squeeze the nickel plate to fix it, and then the cutting blade can cut the nickel plate. When the drive plate continues to move downward, it can cause the cutting platform to flip downward. When the drive plate moves upward, the one-way clamp can push the nickel plate forward.

[0005] The support platform has side plates on both sides of its upper end, and a top plate is installed on the upper end of the two side plates. A hydraulic rod is provided on the lower surface of the top plate, and a drive plate is fixed to the telescopic end of the hydraulic rod. The drive plate is slidably connected to the two side plates.

[0006] The inner wall of the drive plate is slidably connected with multiple short guide rods, and the pressure plate is fixedly connected to the lower end of the multiple short guide rods. The outer surface of each short guide rod is also fitted with a first spring that cooperates with the pressure plate. The cutting blade is fixedly connected to the lower end of the drive plate.

[0007] Both sides of the upper end of the support platform are slidably connected to long sliding plates, and the inner ends of the two long sliding plates are hinged to short connecting rods. One end of the cutting table is hinged to the support platform, and the other end of the cutting table is hinged to the two short connecting rods. A collection box is placed inside the support platform.

[0008] Both ends of the drive plate are slidably connected to long boxes, and the inner walls of the long boxes are slidably connected to long pins. The inner walls of the long boxes are also provided with second springs that cooperate with the long pins. The long slide plates are provided with long keyways that cooperate with the long pins.

[0009] Each of the inner end faces of the side plates is provided with a track groove that cooperates with the long pin. Each track groove includes a first inclined groove, a wave groove, a second inclined groove, a long vertical groove and an extension groove. The inner wall of the long vertical groove is provided with a first wedge block that cooperates with the long pin, and the inner wall of the first inclined groove is provided with a second wedge block that cooperates with the long pin.

[0010] Each of the unidirectional clamps includes a movable L-shaped support, which is slidably connected to the inner wall of the operating table. The lower end of each L-shaped support is provided with a thickened seat, and the upper end of each L-shaped support is hinged with a wedge-shaped rod.

[0011] Both sides of the operating table are equipped with rotatable discs, and the inner walls of the discs are equipped with rotatable threaded rods. The outer surfaces of the threaded rods are threaded with square sliders. One side of each disc is also equipped with a long connecting rod, one end of which is hinged to the square slider, and the other end of which is hinged to an L-shaped support.

[0012] Each of the inner ends of the disc is coaxially fixed with a spur gear, and each of the two end faces of the operating table is slidably connected with a spur rack, which meshes with the corresponding spur gear.

[0013] Guide plates are fixedly connected to one end face of the spur rack, and short pins are fixedly connected to both end faces of the drive plate. The guide plates are provided with upper inclined grooves and lower vertical grooves that cooperate with the short pins.

[0014] Compared with the prior art, the present invention has the following advantages: In use, place the nickel plate on the operating table and push it to the cutting table position. Activating the hydraulic rod will drive the drive plate downwards. Initially, the pressure plate contacts the nickel plate before the cutting blade, and is flexibly pressed and fixed by the first spring. The cutting blade then completes a fixed-length cut. During this process, the short pins on both sides push the rack backwards along the upper inclined groove of the guide plate. Through the transmission of the spur gear, rack, and long connecting rod, the one-way clamp returns to its original position. When the short pins enter the lower vertical groove, they return to their original position. After cutting, the drive plate moves upwards, and the short pins first travel upwards in the lower vertical groove. After the pressure plate leaves the plate surface, the short pins enter the upper inclined groove, driving the one-way clamp to push the nickel plate forward a fixed distance, achieving automatic fixed-length feeding. Simultaneously, guided by the trajectory groove and wedge block, the long pins enter the first inclined groove and wave groove from the extension groove, causing the cutting table to tilt downwards. The cutting debris is poured into a collection box, and the table surface is thoroughly cleaned by reciprocating vibration. Finally, it is reset to a horizontal position via a second inclined groove. The entire device achieves high-level linkage between clamping, cutting, automatic feeding, and table surface cleaning through a single hydraulic drive, eliminating the need for an additional independent conveying control system. This effectively ensures the coordination and feeding accuracy of continuous fixed-length cutting, significantly improving production efficiency. The table surface flipping and vibration cleaning performed simultaneously after each cutting can remove debris in time, eliminating positioning errors and potential scratches on the board surface caused by debris padding or adhesion. Long-term operation can maintain stable cutting accuracy and product surface quality, greatly reducing the burden of manual cleaning. In addition, the position of the square slider can be adjusted by rotating the threaded rod, flexibly changing the feeding stroke of the unidirectional clamp, easily adapting to different fixed-length requirements, making it convenient to use and highly versatile.

Detailed Implementation

[0028] like Figures 1-12 As shown, the present invention provides a nickel plate fixed-length cutting device, including a base plate 1. The base plate 1 is provided with a support platform 3 and an operating platform 2 at its upper end. The support platform 3 is provided with a cutting platform 14 at its upper end. The support platform 3 is also provided with a drive plate 9 that can move up and down at its upper end. The drive plate 9 is provided with a cutting blade 37 at its lower end and a pressure plate 13 at its lower end. A nickel plate is placed on the upper end of the operating platform 2. Both sides of the operating platform 2 are provided with conveying mechanisms. Each conveying mechanism includes a one-way clamp. When the drive plate 9 moves downward, the pressure plate can first squeeze the nickel plate to fix it, and then the cutting blade 37 can cut the nickel plate. When the drive plate 9 continues to move downward, the cutting platform 14 can be flipped downward. When the drive plate 9 moves upward, the one-way clamp can push the nickel plate forward.

[0029] like Figures 1-5As shown, the base plate 1 supports the entire device. The operating table 2 and support table 3 are both fixed to the upper end of the base plate 1 via support legs. Through the cutting table 14, when the cutting blade 37 moves downward, it can cut the nickel plate in cooperation with the cutting table 14. Through the cooperation of the pressure plate 13, conveying mechanism (i.e., one-way clamp), and other components, when the drive plate 9 moves downward, the corresponding pressure plate and cutting blade 37 move downward simultaneously. The pressure plate can press and fix the nickel plate, i.e., press the nickel plate onto the upper surface of the cutting table 14, and then the cutting blade 37 can cut the nickel plate. After the nickel plate is cut, when the drive plate 9 continues to move downward, it can drive the cutting table 14 to flip downward. When the cutting table 14 flips downward, the impurities remaining on the upper end of the cutting table 14 can be poured into a designated position. When the drive plate 9 moves upward to reset, it can simultaneously drive the pressure plate and cutting blade 37 to move downward. The cutter 37 moves upward to reset and simultaneously drives the unidirectional clamp to move forward. As the unidirectional clamp moves forward, it moves the nickel plate forward, thus performing a fixed-length cut on the nickel plate. By designing the conveying mechanism and the cutting device to work in tandem, the nickel plate can be automatically conveyed forward to the specified length after each cut, preparing for the next cut. This eliminates the need for an independent conveying control system, effectively ensuring the coordination and accuracy of continuous fixed-length cutting and improving production efficiency. At the same time, the device can simultaneously clean the cutting table 14 after each cut, promptly removing the debris generated during cutting and preventing debris from adhering and accumulating on the table surface. This keeps the cutting table 14 clean, eliminating positioning errors and potential damage to the plate surface caused by debris. Long-term operation can maintain stable cutting accuracy and product surface quality, and significantly reduces the burden of manual cleaning.

[0030] The support platform 3 has side plates 6 on both sides of its upper end, and a top plate 7 is installed on the upper end of the two side plates 6. A hydraulic rod 8 is provided on the lower surface of the top plate 7. A drive plate 9 is fixed to the telescopic end of the hydraulic rod 8 and is slidably connected to the two side plates 6.

[0031] like Figure 3 As shown, the side plates 6 are all fixed to the upper surface of the support platform 3, and the top plate 7 is fixed to the upper end of the side plates 6 by the support column; the drive plate 9 can slide up and down on the outer end face of the side plate 6, that is, the limit drive plate 9 can only move up and down. When the hydraulic rod 8 works, it can drive the drive plate 9 to move up and down. The hydraulic rod 8 is existing technology and will not be described in detail.

[0032] Multiple short guide rods 10 are slidably connected to the inner wall of the drive plate 9. The pressure plate 13 is fixedly connected to the lower end of the multiple short guide rods 10. The outer surface of each short guide rod 10 is also fitted with a first spring 11 that cooperates with the pressure plate 13. The cutting blade 37 is fixedly connected to the lower end of the drive plate 9.

[0033] like Figures 3-4As shown, the short guide rod 10 can slide up and down on the inner wall of the drive plate 9. The upper end of the short guide rod 10 is fixed with an anti-detachment pad 12 to prevent the short guide rod 10 from detaching from the drive plate 9. Under the limitation of the short guide rod 10, the pressure plate 13 can only move up and down at the lower end of the drive plate 9. The first spring 11 always exerts a downward driving force on the pressure plate 13, even when the pressure plate 13 is in the lowest position under normal conditions. When the drive plate 9 moves downward, it can drive the pressure plate 13, the cutting blade 37, the short guide rod 10 and other components to move downward synchronously. When the pressure plate 13 moves downward and contacts the nickel plate, it can press and fix the nickel plate. When the drive plate 9 continues to move downward, it can compress the first spring 11 and drive the cutting blade 37 to move downward, thereby cutting the nickel plate.

[0034] Both sides of the upper end of the support platform 3 are slidably connected to long sliding plates 36, and the inner ends of the two long sliding plates are hinged to short connecting rods 41. One end of the cutting table 14 is hinged to the support platform 3, and the other end of the cutting table 14 is hinged to the two short connecting rods 41. A collection box 4 is placed inside the support platform 3.

[0035] like Figure 3 and Figure 5 As shown, the long slide plate 36 can slide back and forth on the upper surface of the support platform 3. Both sides of the upper surface of the support platform 3 are fixed with arched seats. The cutting table 14 is rotatably connected to the arched seats through a hinge shaft. Even if the cutting table 14 can flip up and down, when the long slide plate 36 moves back and forth, it can drive the lower end of the short connecting rod 41 to move back and forth. The upper end of the short connecting rod 41 will drive the cutting table 14 to flip up and down. When the cutting table 14 flips down, it can pour the debris on the upper end of the cutting table 14 into the collection box 4.

[0036] Both ends of the drive plate 9 are slidably connected to long boxes 15, and long pins 17 are slidably connected to the inner walls of the long boxes 15. The inner walls of the long boxes 15 are also provided with second springs 16 that cooperate with the long pins 17. Long keyways that cooperate with the long pins 17 are opened on the long slide plates 36.

[0037] like Figures 4-6 As shown, the long pin 17 can slide left and right on the inner wall of the long box 15. The second spring 16 always has an outward driving force on the long pin 17. Even if the long pin 17 is in the extended state under normal conditions, the long box 15 can slide back and forth on the inner wall of the drive plate 9. When the drive plate 9 moves up and down, it can drive the long box 15, the long pin 17 and so on to move up and down synchronously. That is, the corresponding long pin 17 can slide up and down along the inner wall of the long keyway. When the long box 15 and the long pin 17 move back and forth, under the contact engagement between the long keyway and the long pin 17, the long slide plate 36 can be driven to move back and forth, that is, the cutting table 14 can be driven to flip up and down.

[0038] The inner end face of the side plate 6 is provided with a track groove that cooperates with the long pin 17. The track groove includes a first inclined groove 20, a wave groove 18, a second inclined groove 19, a long vertical groove 21 and an extension groove 22. The inner wall of the long vertical groove 21 is provided with a first wedge block 23 that cooperates with the long pin 17, and the inner wall of the first inclined groove 20 is provided with a second wedge block 24 that cooperates with the long pin 17.

[0039] like Figures 6-8As shown, both the first wedge block 23 and the second wedge block 24 have inclined surfaces and straight surfaces. When the drive plate 9, the long box 15, and the long pin 17 move downwards synchronously, the long box 15 can move vertically downwards under the engagement of the long pin 17 and the long vertical groove 21, meaning that the corresponding long slide plate 36 will not move back and forth. When the drive plate 9 continues to move downwards, the pressure plate 13 can press and fix the nickel plate, and the cutting blade 37 can cut the nickel plate. At the same time, the long pin 17 can meet the first wedge block 23, and the first wedge block 23... Under the inclined contact engagement, the long pin 17 can move inward to compress the second spring 16. When the long pin 17 moves downward to disengage from the first wedge block 23, it can then pop outward under the force of the second spring 16. At this time, the long pin 17 enters the inner wall of the extension groove 22. After the nickel plate is cut, when the drive plate 9 moves upward to reset, that is, when the corresponding long pin 17, cutting blade 37, pressure plate 13, etc., move upward to reset, the pressure plate 13 can move upward and no longer squeeze the nickel plate. When moving upwards, under the direct blocking action of the first wedge block 23, the long pin 17 can slide from the inner wall of the extension groove 22 into the inner wall of the first inclined groove 20. That is, through the setting of the first wedge block 23, the long pin 17 can change its trajectory when sliding upwards and enter the inner wall of the first inclined groove 20, without entering the inner wall of the long vertical groove 21. When the drive plate 9, the long pin 17, etc. continue to move upwards, the long pin 17 can move backwards under the engagement of the first inclined groove 20. When the long pin 17 moves backwards, it can drive the long slide plate 3. 6. Move backward and the cutting table 14 flips downward. When the cutting table 14 flips downward, the debris stored on the upper part of the cutting table 14 can be poured into the collection box 4. When the long pin 17 continues to move upward and enters the inside of the wave groove 18, the long pin 17 can oscillate back and forth. At this time, the corresponding long slide plate 36 can oscillate back and forth. That is, the corresponding cutting table 14 can flip downward to the bottom and then oscillate up and down. Thus, under the action of inertia, the debris can be thoroughly cleaned and the upper surface of the cutting table 14 can be kept clean and tidy.When the long pin 17 moves upward and enters the second inclined groove 19, it can move forward to reset, meaning the corresponding long slide plate 36 moves forward to reset, and the cutting table 14 can flip upward to reset. When the long pin 17 moves upward and meets the inclined surface of the second wedge block 24, it can move inward again to compress the second spring 16. When the long pin 17 moves upward and enters the inner wall of the long vertical groove 21, it can disengage from the second wedge block 24, meaning it can move outward under the elastic force of the second spring 16, meaning the corresponding long slide plate 36 moves forward to reset. The top position and the cutting table 14 are flipped upwards to a horizontal state, so that the upper surface of the cutting table 14 can be cleaned in time after cutting. The second wedge block 24 allows the long pin 17 to slide unidirectionally from the inner wall of the second inclined groove 19 into the inner wall of the long vertical groove 21 when it moves upwards. When the long pin 17 slides downwards from the inner wall of the long vertical groove 21 again, the straight surface of the second wedge block 24 prevents the long pin 17 from entering the second inclined groove 19; instead, the long pin 17 slides downwards along the inner wall of the long vertical groove 21. This allows the long pin 17 to move repeatedly along the track groove, realizing the coordinated work of each part.

[0040] Each of the unidirectional clamps includes a movable L-shaped support 33, which is slidably connected to the inner wall of the operating table 2. The lower end of each L-shaped support 33 is provided with a thickened seat 34, and the upper end of each L-shaped support 33 is hinged with a wedge-shaped rod 35.

[0041] like Figures 9-12 As shown, the L-shaped support 33 can slide back and forth on the inner wall of the operating table 2. When the one-way clamp moves from front to back, it will not clamp or fix the nickel plate. When the one-way clamp moves from back to front, it can clamp the nickel plate and push it forward to the designated position. The installation and shape of the wedge-shaped rod 35 and the thickened seat 34 are as follows: Figure 12 As shown, when the wedge 35 is not under force, it can be vertically downward. When a nickel plate is placed on the operating table 2, the wedge 35 can tilt to one side and its bottom contacts the upper surface of the nickel plate, and the thickened seat 34 can contact the lower surface of the nickel plate. At this time, when the L-shaped support 33 moves from front to back, the bottom of the wedge 35 can slide with the nickel plate, that is, it will not clamp or drive the nickel plate. When the L-shaped support moves from back to front, the bottom of the wedge 35 contacts the upper surface of the nickel plate. The wedge 35 flips downward and is blocked by the nickel plate, which can clamp and fix the nickel plate, that is, drive the nickel plate to move forward synchronously to the designated position, thereby realizing fixed-length cutting.

[0042] Both sides of the operating table 2 are provided with rotatable discs 26. The inner wall of each disc 26 is provided with a rotatable threaded rod 29. The outer surface of each threaded rod 29 is threaded with a square slider 31. Each disc 26 is also provided with a long connecting rod 32 on one side. One end of each long connecting rod 32 is hinged to the square slider 31, and the other end of each long connecting rod 32 is hinged to the L-shaped support 33.

[0043] like Figures 10-11 As shown, a rotating shaft is fixedly connected to the inner wall of the center of the disc 26, and a bearing seat is rotatably connected to the outer surface of the rotating shaft. The bottom end of the bearing seat is fixedly connected to both sides of the upper surface of the operating table 2, limiting the disc 26 to rotate only. The threaded rod 29 is rotatably connected to the inner wall of the disc 26, and the square slider 31 can slide inward or outward on the inner wall of the disc 26. A first handle 30 is fixedly connected to one side of the outer surface of the threaded rod 29. When the first handle 30 rotates, it can drive the square slider 31 to move inward or outward through the threaded connection with the square slider 31. The square slider 31 can be moved outward to adjust its initial position. It also has a self-locking function due to the threaded connection between the threaded rod 29 and the square slider 31. That is, the position of the square slider 31 is fixed when the threaded rod 29 is not rotating. When the disc 26 rotates back and forth, the unidirectional clamp can be driven to move back and forth through the hinge between the square slider 31 and the long connecting rod 32. When the square slider 31 moves inward or outward, the size of the reciprocating stroke of the unidirectional clamp can be changed, and it can be adjusted adaptively according to the cutting requirements.

[0044] Each inner end of the disc 26 is coaxially fixed with a spur gear 38, and each side end of the operating table 2 is slidably connected with a rack 39, which meshes with the corresponding spur gear 38.

[0045] like Figures 10-11 As shown, a rotating shaft is fixed to the inner wall of the center of the spur gear 38 and the disk 26, that is, when the spur gear 38 rotates, it can drive the disk 26 to rotate; the rack 39 can slide back and forth on both ends of the operating table 2. When the rack 39 moves forward or backward, it can drive the spur gear 38 and the disk 26 to rotate back and forth through meshing with the spur gear 38, that is, the corresponding one-way clamp moves back and forth.

[0046] Guide plates are fixedly connected to one side of the straight rack 39, and short pins 25 are fixedly connected to both sides of the drive plate 9. The guide plates are provided with upper inclined grooves 28 and lower vertical grooves 40 that cooperate with the short pins 25.

[0047] like Figure 10As shown, the guide plate, when moving back and forth, drives the rack 39 to move back and forth, i.e., the corresponding disc 26 reciprocates in both directions and the one-way clamp moves back and forth. When the drive plate 9 and the short pin 25 move downwards, the engagement of the short pin 25 with the upper inclined groove 28 drives the rack 39 to move backwards, i.e., the corresponding one-way clamp moves backwards. When the drive plate 9, the short pin 25, etc., continue to move downwards, causing the short pin 25 to enter the inner wall of the lower vertical groove 40, the short pin 25 no longer drives the guide plate to move backwards, i.e., the corresponding one-way clamp moves backwards to the designated position. At this time, when the drive plate 9 continues to move downwards... The pressure plate 13 can press and fix the nickel plate, and the cutting blade 37 can cut the nickel plate. After the cutting is completed, when the drive plate 9, short pin 25 and other components move from bottom to top to reset, the short pin 25 moves upward on the inner wall of the lower vertical groove 40. That is, it will not immediately drive the one-way clamp to move forward to reset. When the drive plate 9, short pin 25 and other components move upward to make the short pin 25 enter the inner wall of the upper inclined groove 28, the drive plate 9 moves upward to make the pressure plate 13 disengage from the nickel plate. That is, it no longer presses and fixes the nickel plate. The corresponding one-way clamp can push the nickel plate forward to the designated position. Thus, after cutting, the nickel plate is pushed forward in a progressive manner for fixed-length cutting.

[0048] In use, the nickel plate is placed on the operating table 2 and pushed to the cutting table 14. Activating the hydraulic rod 8 drives the drive plate 9 downwards. Initially, the pressure plate 13 contacts the nickel plate before the cutting blade 37, and is flexibly pressed and fixed by the first spring 11. Then, the cutting blade 37 completes a fixed-length cut. During this process, the short pins 25 on both sides push the rack 39 backwards along the upper inclined groove 28 of the guide plate. Through the transmission of the spur gear 38, rack 39, and long connecting rod 32, the one-way clamp returns to its original position. When the short pins 25 enter the lower vertical groove 40, they return to their original position. After cutting, the drive plate 9 moves upwards, and the short pins 25 first travel upwards within the lower vertical groove 40. After the pressure plate 13 leaves the plate, the short pins 25 enter the upper inclined groove 28, driving the one-way clamp to push the nickel plate forward a fixed distance, achieving automatic fixed-length feeding. Simultaneously, the long pin 17, guided by the track groove and wedge block, enters the first... The inclined groove 20 and the wave groove 18 drive the cutting table 14 to first flip downwards to pour the cutting debris into the collection box 4, and then thoroughly clean the table surface through reciprocating oscillation. Finally, it returns to the horizontal position through the second inclined groove 19. The entire device achieves a high degree of linkage between clamping, cutting, automatic feeding and table surface cleaning through a single hydraulic drive. There is no need to configure an additional independent conveying control system, which effectively ensures the coordination and feeding accuracy of continuous fixed-length cutting and significantly improves production efficiency. The table surface flipping and oscillating cleaning performed synchronously after each cutting can remove debris in time and eliminate the positioning error and potential scratches on the board surface caused by debris padding or adhesion. It can maintain stable cutting accuracy and product surface quality even after long-term operation, greatly reducing the burden of manual cleaning. In addition, the position of the square slider 31 can be adjusted by rotating the threaded rod 29, which can flexibly change the feeding stroke of the one-way clamp and easily adapt to different fixed-length requirements. It is convenient to use and highly versatile.
