Description

Technical Field

[0001] The present application relates to the technical field of automobile sealing strip processing, and in particular to an automatic punching device for cutting the upper end of a sealing strip top strip. Background Art

[0002] In modern automobile manufacturing, the quality of automobile sealing strips directly affects the sealing, comfort and safety of the vehicle. Sealing strips are usually used to fill the gaps between the components of the vehicle body to prevent the intrusion of water, dust and noise. During the production and processing of sealing strips, a long sealing strip is usually formed, and then it is roughly cut according to the required length of the sealing strip to obtain a predetermined length of sealing strip. Then, according to the actual production and processing requirements, the surface of the sealing strip is precision processed, such as punching or cutting.

[0003] In the early days, the cutting of sealing strips usually required the sealing strips to be fixed at multiple positions, and the blades had to be manually operated to cut the surface of the sealing strips, and then the excess waste had to be removed. This cutting method was not only complicated, but also the manual cutting made it difficult to ensure that the size of the sealing strips was the same after cutting, which affected the sealing performance of the car.

[0004] Some automated cutting equipment has also appeared on the market, such as the Chinese patent application "A Cutting Device for Automobile Sealing Strips", application number: CN202222448703.3; the supporting assembly, cutting assembly, clamping assembly and sliding assembly are disclosed, the supporting assembly includes a base, a vertical plate is arranged on the base, and a top plate is arranged on the top of the two vertical plates; the cutting assembly includes a mounting plate, a knife seat is arranged on the mounting plate, and a cutting blade is arranged on the knife seat; the clamping assembly includes a supporting plate, a supporting block is arranged on the supporting plate, a cylinder fixing plate is arranged on the supporting block, a waste clamping cylinder and a finished product clamping cylinder are arranged on the cylinder fixing plate, the waste clamping cylinder and the finished product clamping cylinder are arranged on both sides of the cutting blade, and the telescopic end of the waste clamping cylinder and the telescopic end of the finished product clamping cylinder abut against the product; the sliding assembly includes a linear module, the linear module is arranged on the base, and the linear module is connected to the supporting plate. The utility model can automatically complete the cutting of automobile sealing strips, and can ensure the accuracy of the cutting size, ensure the size of the sealing strip after cutting, and improve the sealing performance of the sealing strip.

[0005] However, the existing sealing strip cutting technology has some shortcomings, especially in terms of accuracy and automation. The sealing strip top strip structure involved in this application, such as Figure 1As shown in the figure, the sealing strip has a large overall length and a soft structure. The sealing strip is easy to deform when subjected to force. For this reason, when processing and cutting a narrow notch in the sealing strip, the processing blade needs to be cut along the length direction of the sealing strip. The sealing strip is soft and easy to deform, and it is difficult to ensure the cutting accuracy, resulting in low product precision. In view of the technical problems existing in the sealing strip cutting process, a high-precision automatic punching equipment is developed to effectively improve the production efficiency and quality of the sealing strip and meet the high standards of the modern automotive industry for sealing strips. Summary of the invention

[0006] The technical problem to be solved by the present application is to provide an automatic punching device for cutting the upper end of the top strip of the sealing strip. By optimizing the mounting seat structure and accurately controlling the cutting process, the processing accuracy and quality of the sealing strip are effectively improved to meet the high standards of the modern automobile industry.

[0007] The technical solution adopted in the present application is: an automatic punching device for cutting the upper end of the top strip of the sealing strip, comprising a frame, a slide rail and a mounting seat for mounting the sealing strip are arranged on the frame, the mounting seat and the slide rail are arranged parallel to each other, and a cutting device is installed on the slide rail. The mounting seat is a strip-shaped structural member that adapts to the sealing strip. The sealing strip to be processed is assembled to the top of the mounting seat. The mounting seat is provided with a narrow and long slot along its length direction. The slot runs through the top and bottom surfaces of the mounting seat. A support plate is installed at the slot. The length of the support plate is adapted to the length of the sealing strip. A sawtooth group is provided on the top surface of the support plate. The sawtooth group acts on the surface of the sealing strip located on the mounting seat. The sawtooth group limits the movement of the sealing strip. The cutting device moves along the slide rail to cut the sealing strip on the mounting seat.

[0008] Compared with the prior art, the advantage of the present application is that the device realizes automatic cutting of the sealing strip, reduces the need for manual operation, reduces the possibility of human error, and improves production efficiency.

[0009] During the sealing strip cutting process, since the cutting device needs to move along the sealing strip, it is necessary to make space for the movement of the cutting device at the position where the processing is required, that is, it is impossible to set a pressed structure at the position where the sealing strip needs to be processed, which causes the sealing strip to move easily when it is under force, and then causes processing deviation. In view of this, a mounting seat structure is designed. The setting of the mounting seat enables the sealing strip to be installed stably and reliably, and effectively limits the movement of the sealing strip during the cutting process, reduces deformation, and ensures the accuracy of cutting. The present application designs a narrow and long notch and cooperates with the installation support plate. A sawtooth group is provided on the top surface of the support plate. The sawtooth group acts on the surface of the sealing strip located on the mounting seat, which can effectively limit the movement of the sealing strip. On this basis, through the combination of the slide rail and the cutting device, the movement stroke during the cutting process can be accurately controlled to ensure that the length and angle of each cutting are consistent, thereby improving the processing accuracy. Through precise cutting technology, the present application can effectively improve the quality of the sealing strip and meet the high standards of the modern automotive industry for sealing strips.

[0010] In some embodiments of the present application, a lifting device is installed under the support plate, and the lifting device drives the support plate to move up and down. The upward movement of the support plate drives the sealing strip to move upward synchronously and detach from the mounting seat.

[0011] The design of the lifting device makes the disassembly process of the sealing strip more convenient. The sealing strip can be easily removed from the mounting seat, reducing the complexity of manual operation. At the same time, it effectively avoids deformation or damage to the sealing strip during the disassembly process, ensuring the integrity and accuracy of the sealing strip during processing and use.

[0012] In some embodiments of the present application, the sawtooth group includes a left-pointing sawtooth segment and a right-pointing sawtooth segment, the left-pointing sawtooth segment is provided with sharp teeth inclined to the left, and the right-pointing sawtooth segment is provided with sharp teeth inclined to the right.

[0013] By setting the sharp teeth inclined to the left to act on the inner bottom surface of the sealing strip, the movement of the sealing strip to the right can be effectively restricted. Similarly, the sharp teeth inclined to the right can effectively restrict the movement of the sealing strip to the left. The left and right movement of the sealing strip during the cutting process is effectively restricted, ensuring that the sealing strip remains stable during processing and reducing the cutting deviation caused by movement.

[0014] It should be noted that in the actual application of the sealing strip, the outer surface of the sealing strip is exposed, so the integrity of the outer surface of the sealing strip needs to be ensured, and damage is a quality issue. However, the inner bottom surface of the sealing strip, that is, the surface where the sealing strip contacts the support plate, is the assembly surface and can be fixed according to processing requirements.

[0015] In some embodiments of the present application, the cutting device is located on one side of the head end of the support plate, and the head end of the support plate is provided with at least one group of saw teeth, recorded as saw tooth group one; the tail end of the support plate is provided with a group of saw teeth, recorded as saw tooth group two, and the saw tooth group two is arranged close to the notch of the sealing strip.

[0016] The design of the sawtooth group enables the sealing strip to be effectively fixed during the cutting process, preventing it from moving during the processing, ensuring the stability and accuracy of the cutting. By setting the sawtooth group at different positions, the limiting capacity of the sawtooth group can be effectively utilized to ensure the quality of the sealing strip during cutting.

[0017] In some embodiments of the present application, a rotating downward-pressing cylinder is provided on the frame, and the rotating downward-pressing cylinder is connected to a pressure block through a cross bar. The pressure block and the cross bar are connected by a spring assembly. The rotating downward-pressing cylinder drives the pressure block to move downward to act on the surface of the sealing strip on the second sawtooth group, and the bottom surface of the pressure block is adapted to the top surface structure of the sealing strip.

[0018] In the present application, the sealing strip is installed by means of an elastically connected pressing block. Compared with hard pressing, the present application can avoid scratching and crushing the surface of the sealing strip, ensuring that the surface shape of the sealing strip is intact. In addition, the position of the pressing block designed in the present application avoids the notch that needs to be cut in the sealing strip, but is close to the notch, which can achieve a good pressing effect without affecting the cutting process of the sealing strip.

[0019] The pressing block rotates and presses down to apply pressure to the sealing strip, ensuring the stability of the sealing strip during the cutting process, reducing deformation caused by the cutting force, thereby improving the cutting accuracy and ensuring the smooth progress of the cutting process. The design of the spring component provides elastic buffering, which can absorb part of the impact force, reduce damage to the surface of the sealing strip, and protect the integrity of the sealing strip.

[0020] In some embodiments of the present application, the cutting device includes a profiling component and a cutting knife group, the profiling component includes a profiling seat, and at least one profiling block installed on the profiling seat, the end face of the profiling block is in contact with the surface of the sealing strip, the cutting knife group includes a double-stroke cylinder and a knife seat, and the knife seat is respectively equipped with a cutting blade and a cutting blade, the double-stroke cylinder is connected to the cutting blade and the cutting blade, and the double-stroke cylinder drives the cutting blade or the cutting blade to move down for cutting or rise up for retracting the blade when it works, and the knife seat is installed on the profiling seat, and the cutting device moves along the slide rail to cut the sealing strip on the mounting seat.

[0021] Specifically, there is a distance between the cutting blade and the scoring blade. Compared with the scoring blade, the cutting blade is closer to the sealing strip. The scoring blade moves down to the cutting position. At this time, the scoring device moves a predetermined length along the slide rail. The scoring blade scores the lip of the sealing strip during the movement. When the scoring process is completed, the scoring blade rises and retracts. The scoring device retreats along the slide rail so that the cutting blade moves to the cutting position. The cutting blade moves down to cut the lip of the sealing strip that has been scored. After the cutting process is completed, the cutting blade rises and retracts. The scoring device moves to the initial position along the slide rail.

[0022] By arranging a double-stroke cylinder and a knife seat, the movement stroke of the slicing blade and the cutting blade can be precisely controlled, which can ensure that the length and angle of each cut are consistent, thereby improving the processing accuracy of the sealing strip.

[0023] The design of the profiling component enables the present application to contact and connect with the outer surface of the sealing strip when cutting the sealing strip, thereby limiting the deformation of the sealing strip during cutting, ensuring the accuracy of cutting, and further improving the processing accuracy of the sealing strip. The introduction of automatic punching equipment makes the entire processing process of the sealing strip smoother, and can complete more processing tasks in a shorter time, thereby improving the overall production efficiency.

[0024] In some embodiments of the present application, a top profiling block, an inner profiling block and an outer block are respectively installed on the profiling seat, the bottom surface structure of the top profiling block is adapted to the top surface structure of the sealing strip, and the end of the inner profiling block is adapted to the structure of the sealing strip on the side close to the slide rail; when the profiling assembly moves to the location of the sealing strip, the top profiling block acts on the top surface of the sealing strip and contacts and connects with the top surface of the sealing strip, and the end of the inner profiling block is embedded in one side of the sealing strip and contacts with one side of the sealing strip.

[0025] The top profiling block and the inner profiling block are adapted to the top surface and the side structure of the sealing strip, which can ensure perfect fit with the sealing strip during the cutting process, reduce the error during cutting, and improve the cutting accuracy.

[0026] Through the design of the top profiling block and the inner profiling block, the deformation of the sealing strip during the cutting process can be limited, the accuracy of the cutting is ensured, and the product quality is improved.

[0027] In some embodiments of the present application, a locking hole is provided on the contour seat, and a scale mark is provided on the outer periphery of the locking hole; a waist-shaped hole is correspondingly provided on the outer block, and a locking piece passes through the waist-shaped hole and is fixedly connected to the locking hole; a plurality of rollers are installed under the outer block through a rotating shaft; when the contour assembly moves to the location of the sealing strip, the outer peripheral surface of the roller is attached to the other side of the sealing strip away from the slide rail; when the contour assembly moves, the roller rotates around the rotating shaft under the action of the friction force exerted by the sealing strip.

[0028] The position of the outer block can be adjusted by the waist hole and the locking piece, thereby adjusting the friction between the roller and the sealing strip. The design of the roller can effectively fit the outer side of the sealing strip, provide additional support, enhance the stability of the sealing strip during the cutting process, and reduce its displacement during the processing. The rotation of the roller can reduce the friction resistance between the surface of the sealing strip, making the contouring component move more smoothly, reducing damage to the surface of the sealing strip and protecting the integrity of the sealing strip. By applying uniform pressure on the outside of the sealing strip, the roller can ensure that the position of the sealing strip remains unchanged during the cutting process, thereby improving the accuracy and consistency of the cutting.

[0029] In some embodiments of the present application, there is a predetermined spacing between the top profiling block and the inner profiling block for the lip edge of the sealing strip to be cut to extend into.

[0030] The predetermined spacing design allows the lip of the sealing strip to be inserted accurately, ensuring accurate alignment during the cutting process and improving the cutting accuracy. By setting the spacing, it is possible to avoid interference from other parts of the sealing strip with the lip to be cut, ensuring a smooth cutting process and preventing accidental cutting of other parts of the sealing strip. The lip insertion design can increase the stability of the sealing strip during the cutting process, reduce deformation or displacement caused by cutting, and ensure cutting accuracy.

[0031] In some embodiments of the present application, a mounting groove is provided on the profiling seat, the mounting groove is located in the middle part of the profiling seat, the bottom of the knife seat is embedded in the mounting groove and connected to the profiling seat, a side of the top profiling block close to the knife seat is recorded as the first side of the top profiling block, the first side is an inclined surface and a cutting surface parallel to the lip of the sealing strip, and a side of the cutting blade and a side of the slicing blade are arranged to fit the first side of the top profiling block.

[0032] The bottom of the knife seat is embedded in the mounting groove, providing a stable connection to ensure that the relative position of the knife and the profiling seat will not shift during the cutting process, thereby improving the cutting accuracy. The cutting blade and the scriber blade fit the first side of the top profiling block to ensure the stability of the blade during the cutting process, further improving the cutting accuracy and consistency. The design of the inclined surface can ensure the accurate cutting angle of the sealing strip lip.

[0033] In the present application, the knife seat is located in the middle of the entire profiling seat, that is, there are profiling blocks in front and behind the cutting knife group to fill and act on the sealing strip, so that the sealing strip at the cutting point is fully filled to the extent of reducing deformation. Cutting in this state can effectively improve the processing accuracy of the sealing strip.

[0034] In some embodiments of the present application, a waste groove is provided on the top surface of the inner profiling block, the waste groove passes through one end surface of the inner profiling block, an inner wall surface on one side of the waste groove is recorded as a first side surface of the waste groove, and the first side surface of the waste groove and the first side surface of the top profiling block are located in the same plane; the lip of the sealing strip extending between the top profiling block and the inner profiling block is cut by a cutting blade to separate the sealing strip and the waste, and the waste is cut by a cutting blade, and the waste falls into the waste groove and is then discharged.

[0035] That is to say, when the cutting blade or the scribing blade moves up and down (switching between cutting or finishing states), it is always in contact with the first side surface of the top contour block and / or the first side surface of the waste trough, which can effectively ensure the stability and reliability of the movement of the cutting blade and the scribing blade, thereby improving the scribing accuracy.

[0036] The waste chute setting effectively avoids the waste generated by cutting from affecting the sealing strip, and isolates the two well.

[0037] In some embodiments of the present application, one end surface of the top profiling block close to the sealing strip and one end surface of the inner profiling block close to the sealing strip are configured as rounded tips.

[0038] The above structure allows the top profiling block and the inner profiling block to be smoothly inserted into the gaps on the outer surface of the sealing strip, ensuring full fit with the outer surface of the sealing strip. The rounded tip design can effectively avoid scratches and damage to the surface of the sealing strip, protecting the integrity of the sealing strip.

[0039] In some embodiments of the present application, an insert is further provided at one end of the contour seat close to the sealing strip, and one end of the insert constitutes an outer contour block, which is adapted to the structure of the sealing strip on the side away from the slide rail; when the contour assembly moves to the location of the sealing strip, the lower bottom surface of the insert acts on the top surface of the sealing strip, and the outer contour block is embedded in the other side of the sealing strip to regularly expand the structure of the other side of the sealing strip, and the outer contour block is located directly in front of the roller.

[0040] That is, the outer profiling block is used to regularly expand the structure of the other side of the sealing strip, and then the roller is inserted. This prevents the roller structure from being too large to be smoothly inserted into the side of the sealing strip. Specifically, the outer profiling block is configured with a rounded tip at one end surface close to the sealing strip. The rounded tip design can effectively avoid scratches and damage to the surface of the sealing strip and protect the integrity of the sealing strip.

[0041] In some embodiments of the present application, a pressure roller assembly is further provided at one end of the insert close to the sealing strip. The pressure roller assembly is located above the sealing strip. The pressure roller assembly includes two pressure rollers. The pressure rollers rotate around the central axis when subjected to force.

[0042] The present application adds a pressure roller assembly. After the cutting device is started, the pressure roller assembly is the first component to contact the sealing strip. The pressure roller assembly can further act on the sealing strip. If the sealing strip is partially warped, the pressure roller assembly will apply force downward to the warped portion to ensure that the sealing strip has been fully installed and cooperate with the subsequent cutting process.

[0043] In some embodiments of the present application, the contact surfaces of the top profiling block, the inner profiling block and the sealing strip, and the contact surfaces of the insert and the sealing strip are all provided with anti-wear coatings, and the anti-wear coatings are made of Teflon material.

[0044] The anti-wear coating made of Teflon can effectively prevent the top profiling block and the inner profiling block from causing scratches on the surface of the sealing strip when they come into contact with the sealing strip.

[0045] In some embodiments of the present application, a control device is further included, and a sensor for sensing whether a sealing strip is installed on the mounting seat is provided at one end of the mounting seat close to the cutting device, and the sensor is electrically connected to the control device.

[0046] In the present application, various power devices are electrically connected to the control device respectively. The power devices include lifting devices, rotary downward pressure cylinders, double-stroke cylinders, etc.

[0047] The above-mentioned implementation modes can be combined arbitrarily based on the common knowledge in the art. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0051] The present application is described in detail below in conjunction with the accompanying drawings.

[0052] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0053] Automatic punching equipment for cutting the upper end of the sealing strip top strip, embodiment 1 Figure 1 to Figure 2 As shown: it includes a frame 1, on which a slide rail 2 and a mounting seat 3 for mounting a sealing strip 40 are arranged, the mounting seat 3 and the slide rail 2 are arranged parallel to each other, and a cutting device 4 is installed on the slide rail 2. Through the combination of the slide rail 2 and the cutting device 4, the movement stroke during the cutting process can be accurately controlled to ensure that the length and angle of each cutting are consistent, thereby improving the processing accuracy.

[0054] The mounting seat 3 is a strip-shaped structural member adapted to the sealing strip 40. The sealing strip 40 to be processed is assembled to the top of the mounting seat 3. The setting of the mounting seat 3 enables the sealing strip 40 to be stably and reliably installed, and effectively limits the movement of the sealing strip 40 during the cutting process, reduces deformation, and ensures the accuracy of cutting. The mounting seat 3 is provided with a narrow and long notch along its length direction, and the notch runs through the top and bottom surfaces of the mounting seat 3. A support plate 5 is installed at the notch. The length of the support plate 5 is adapted to the length of the sealing strip 40. A sawtooth group 6 is arranged on the top surface of the support plate 5. The sawtooth group 6 acts on the surface of the sealing strip 40 located on the mounting seat 3, and the sawtooth group 6 limits the movement of the sealing strip 40; the cutting device 4 moves along the slide rail 2 to cut the sealing strip 40 on the mounting seat 3. The narrow and long notch is matched with the mounting support plate 5. The top surface of the support plate 5 is provided with a sawtooth group 6. The sawtooth group 6 acts on the surface of the sealing strip 40 located on the mounting seat 3, and can effectively limit the movement of the sealing strip 40.

[0055] The device realizes automatic cutting of the sealing strip 40, reduces the need for manual operation, reduces the possibility of human error, and improves production efficiency. The present application can effectively improve the quality of the sealing strip 40 through precise cutting technology, and meet the high standard requirements of the modern automobile industry for the sealing strip 40.

[0056] Embodiment 2, as Figures 1 to 4 As shown, a lifting device 7 is installed under the support plate 5. The lifting device 7 drives the support plate 5 to move up and down. The support plate 5 moves upward to drive the sealing strip 40 to move upward synchronously and escape from the mounting seat 3. The design of the lifting device 7 makes the disassembly process of the sealing strip 40 more convenient, and the sealing strip 40 can be easily escaped from the mounting seat 3, reducing the complexity of manual operation, and effectively avoiding deformation or damage to the sealing strip 40 during the disassembly process, ensuring the integrity and accuracy of the sealing strip 40 during processing and use.

[0057] The sawtooth group 6 includes a left-facing sawtooth segment 8 and a right-facing sawtooth segment 9. The left-facing sawtooth segment 8 is provided with sharp teeth arranged obliquely to the left, and the right-facing sawtooth segment 9 is provided with sharp teeth arranged obliquely to the right. By providing the sharp teeth arranged obliquely to the left to act on the inner bottom surface of the sealing strip 40, the movement of the sealing strip 40 to the right can be effectively restricted. Similarly, the sharp teeth arranged obliquely to the right can effectively restrict the movement of the sealing strip 40 to the left. The left and right movement of the sealing strip 40 during the cutting process is effectively restricted, ensuring that the sealing strip 40 remains stable during processing and reducing the cutting deviation caused by movement.

[0058] It should be noted that in the actual application of the sealing strip 40, the outer surface of the sealing strip 40 is exposed, so the integrity of the outer surface of the sealing strip 40 needs to be ensured, and damage is a quality issue. However, the inner bottom surface of the sealing strip 40, that is, the surface where the sealing strip 40 contacts the support plate 5, is an assembly surface and can be fixed according to processing requirements.

[0059] The cutting device 4 is located at one side of the head end of the support plate 5. The head end of the support plate 5 is provided with at least one set of sawtooth groups 6, which are recorded as sawtooth group 6 one; the tail end of the support plate 5 is provided with a set of sawtooth groups 6, which are recorded as sawtooth group 6 two, and the sawtooth group 6 two is arranged close to the notch 41 of the sealing strip 40. The design of the sawtooth group 6 enables the sealing strip 40 to be effectively fixed during the cutting process to prevent it from moving during the processing process, thereby ensuring the stability and accuracy of the cutting. By arranging the sawtooth groups 6 at different positions, the limiting capacity of the sawtooth group 6 can be effectively utilized to ensure the quality of the sealing strip 40 during cutting.

[0060] The frame 1 is provided with a rotating downward pressing cylinder 10, which is connected to a pressure block 11 via a cross bar. The pressure block 11 is connected to the cross bar via a spring assembly 12. The rotating downward pressing cylinder 10 drives the pressure block 11 to move downward and press on the surface of the sealing strip 40 on the second sawtooth group 6. The bottom surface of the pressure block 11 is adapted to the top surface structure of the sealing strip 40. In the present application, the installation of the sealing strip 40 is achieved by means of an elastically connected pressure block 11. Compared with hard pressing, the present application can avoid scratches and crushing on the surface of the sealing strip 40, and ensure that the surface shape of the sealing strip 40 is intact. In the present application, the position of the pressure block 11 is designed to avoid the notch 41 that needs to be cut on the sealing strip 40, but is close to the notch 41. It can have a good pressing effect without affecting the cutting process of the sealing strip 40.

[0061] The pressing block 11 rotates and presses down to apply pressure to the sealing strip 40, ensuring the stability of the sealing strip 40 during the cutting process, reducing deformation caused by the cutting force, thereby improving the cutting accuracy and ensuring the smooth progress of the cutting process. The design of the spring assembly 12 provides elastic buffering, which can absorb part of the impact force, reduce damage to the surface of the sealing strip 40, and protect the integrity of the sealing strip 40.

[0062] The rest of the content of the second embodiment is the same as that of the first embodiment.

[0063] Embodiment three, as Figures 1 to 9As shown, the slicing device 4 includes a profiling component 13 and a slicing knife group 14, the profiling component 13 includes a profiling seat 29, and at least one profiling block installed on the profiling seat 29, the end face of the profiling block is in contact with the surface of the sealing strip 40, the slicing knife group 14 includes a double-stroke cylinder 15 and a knife seat 16, and the knife seat 16 is respectively installed with a slicing blade 17 and a cutting blade 18, the double-stroke cylinder 15 is connected with the slicing blade 17 and the cutting blade 18, and the double-stroke cylinder 15 drives the slicing blade 17 or the cutting blade 18 to move down for cutting or rise up for collection, and the knife seat 16 is installed on the profiling seat 29, and the slicing device 4 moves along the slide rail 2 to cut the sealing strip 40 on the mounting seat 3.

[0064] Specifically, there is a gap between the cutting blade 18 and the dicing blade 17. Compared with the dicing blade 17, the cutting blade 18 is closer to the sealing strip 40. The dicing blade 17 moves down to the cutting position. At this time, the dicing device 4 moves a predetermined length along the slide rail 2. The dicing blade 17 dices the lip of the sealing strip 40 during the movement. When the dicing process is completed, the dicing blade 17 rises and retracts, and the dicing device 4 retreats along the slide rail 2 so that the cutting blade 18 moves to the cutting position, and the cutting blade 18 moves downward to cut the lip of the sealing strip 40 that has been diced. After the cutting process is completed, the cutting blade 18 rises and retracts, and the dicing device 4 moves along the slide rail 2 to the initial position.

[0065] By providing the double-stroke cylinder 15 and the knife seat 16 , the movement strokes of the slicing blade 17 and the cutting blade 18 are precisely controllable, ensuring that the length and angle of each cut are consistent, thereby improving the processing accuracy of the sealing strip 40 .

[0066] The design of the profiling component 13 enables the present application to contact and connect with the outer surface of the sealing strip 40 when cutting the sealing strip 40, thereby limiting the deformation of the sealing strip 40 during cutting, ensuring the accuracy of cutting, and further improving the processing accuracy of the sealing strip 40. The introduction of the automatic punching equipment makes the entire processing process of the sealing strip 40 smoother, and can complete more processing tasks in a shorter time, thereby improving the overall production efficiency.

[0067] The profiling seat 29 is respectively provided with a top profiling block 19, an inner profiling block 20 and an outer block 21. The bottom surface structure of the top profiling block 19 is adapted to the top surface structure of the sealing strip 40, and the end of the inner profiling block 20 is adapted to the structure of the sealing strip 40 near the side of the slide rail 2. When the profiling assembly 13 moves to the location of the sealing strip 40, the top profiling block 19 acts on the top surface of the sealing strip 40 to contact and connect with the top surface of the sealing strip 40, and the end of the inner profiling block 20 is embedded in one side of the sealing strip 40 to contact with one side of the sealing strip 40. The top profiling block 19 and the inner profiling block 20 are adapted to the top surface and one side structure of the sealing strip 40, which can ensure perfect fit with the sealing strip 40 during the cutting process, reduce the error during cutting, and improve the cutting accuracy. Through the design of the top profiling block 19 and the inner profiling block 20, the deformation of the sealing strip 40 during the cutting process can be limited, the accuracy of cutting can be ensured, and the product quality can be improved.

[0068] The profiling seat 29 is provided with a locking hole 22, and a scale mark is set on the outer periphery of the locking hole 22. The outer block 21 is correspondingly provided with a waist-shaped hole 31, and the locking piece 23 passes through the waist-shaped hole and is fixedly connected to the locking hole 22; a plurality of rollers 24 are installed under the outer block 21 through a rotating shaft; when the profiling component 13 moves to the location of the sealing strip 40, the outer peripheral surface of the roller 24 is attached to the other side of the sealing strip 40 away from the slide rail 2; when the profiling component 13 moves, the roller 24 rotates around the rotating shaft under the action of the friction force applied by the sealing strip 40.

[0069] The position of the outer block 21 can be adjusted by the cooperation of the waist-shaped hole and the locking member 23, thereby adjusting the friction between the roller 24 and the sealing strip 40. The design of the roller 24 can effectively fit the outer side of the sealing strip 40, provide additional support, enhance the stability of the sealing strip 40 during the cutting process, and reduce its displacement during the processing process. The rotation of the roller 24 can reduce the friction resistance between the surface of the sealing strip 40, so that the contour component 13 moves more smoothly, reduces damage to the surface of the sealing strip 40, and protects the integrity of the sealing strip 40. By applying uniform pressure on the outer side of the sealing strip 40, the roller 24 can ensure that the position of the sealing strip 40 remains unchanged during the cutting process, thereby improving the accuracy and consistency of the cutting.

[0070] There is a predetermined spacing between the top profiling block 19 and the inner profiling block 20 for the lip of the sealing strip 40 to be cut to extend into. The predetermined spacing design allows the lip of the sealing strip 40 to extend into accurately, ensuring accurate alignment during the cutting process and improving the cutting accuracy. By setting the spacing, it is possible to avoid interference from other parts of the sealing strip 40 with the lip to be cut, ensuring a smooth cutting process and preventing other positions of the sealing strip 40 from being cut by mistake. The lip extension design can increase the stability of the sealing strip 40 during the cutting process, reduce deformation or displacement caused by cutting, and ensure the accuracy of cutting.

[0071] The profiling seat 29 is provided with a mounting groove, which is located in the middle of the profiling seat 29. The bottom of the knife seat 16 is embedded in the mounting groove and connected to the profiling seat 29. The side of the top profiling block 19 close to the knife seat 16 is recorded as the first side of the top profiling block 19. The first side is an inclined surface and parallel to the cutting surface of the lip of the sealing strip 40. One side of the cutting blade 18 and one side of the dicing blade 17 are arranged in contact with the first side of the top profiling block 19. The bottom of the knife seat 16 is embedded in the mounting groove, which provides a stable connection, ensures that the relative position of the tool and the profiling seat 29 will not be displaced during the cutting process, thereby improving the cutting accuracy. The cutting blade 18 and the dicing blade 17 are in contact with the first side of the top profiling block 19, ensuring the stability of the blades during the cutting process, and further improving the cutting accuracy and consistency. The design of the inclined surface can ensure that the cutting angle of the lip of the sealing strip 40 is accurate.

[0072] In the present application, the knife seat 16 is located in the middle of the entire profiling seat 29, that is, there are profiling blocks in front and behind the cutting knife group 14 to fill and act on the sealing strip 40, so that the sealing strip 40 at the cutting point is fully filled to the extent of reducing deformation. Cutting in this state can effectively improve the processing accuracy of the sealing strip 40.

[0073] The top surface of the inner profiling block 20 is provided with a waste groove 25, which passes through one end surface of the inner profiling block 20, and the inner wall surface of one side of the waste groove 25 is recorded as the first side surface of the waste groove 25, and the first side surface of the waste groove 25 and the first side surface of the top profiling block 19 are located in the same plane; the lip edge of the sealing strip 40 extending between the top profiling block 19 and the inner profiling block 20 is cut by the cutting blade 17 to separate the sealing strip 40 and the waste, and the waste is cut by the cutting blade 18, and the waste falls into the waste groove 25 and is then led out. That is to say, when the cutting blade 18 or the cutting blade 17 moves up and down (switching the cutting or finishing state), it is always attached to the first side surface of the top profiling block 19 and / or the first side surface of the waste groove 25, which can effectively ensure the stability and reliability of the movement of the cutting blade 18 and the cutting blade 17, thereby improving the cutting accuracy. The waste groove 25 is set to effectively avoid the waste generated by cutting from affecting the sealing strip 40, and the two are well isolated.

[0074] The end surface of the top profiling block 19 close to the sealing strip 40 and the end surface of the inner profiling block 20 close to the sealing strip 40 are set to be rounded tips. The above structure allows the top profiling block 19 and the inner profiling block 20 to be smoothly inserted into the gaps on the outer surface of the sealing strip 40, ensuring full fit with the outer surface of the sealing strip 40. The rounded tip design can effectively avoid scratches and damages on the surface of the sealing strip 40, protecting the integrity of the sealing strip 40.

[0075] The profiling seat 29 is also provided with an insert 30 at one end close to the sealing strip 40, and one end of the insert 30 constitutes an outer profiling block, which is adapted to the structure of the sealing strip 40 away from the side of the slide rail 2; when the profiling assembly 13 moves to the location of the sealing strip 40, the lower bottom surface of the insert 30 acts on the top surface of the sealing strip 40, and the outer profiling block is embedded in the other side of the sealing strip 40 to regularly open the structure of the other side of the sealing strip 40, and the outer profiling block is located directly in front of the roller 24. That is, after the structure of the other side of the sealing strip 40 is regularly opened by the outer profiling block, the roller 24 is embedded. It is prevented that the roller 24 structure is too large to be smoothly embedded in the side of the sealing strip 40. Specifically, the end surface of the outer profiling block close to the sealing strip 40 is set to a rounded tip. The rounded tip design can effectively avoid scratches and damages on the surface of the sealing strip 40 and protect the integrity of the sealing strip 40.

[0076] The insert 30 is also provided with a pressure roller assembly 26 at one end close to the sealing strip 40. The pressure roller assembly 26 is located above the sealing strip 40. The pressure roller assembly 26 includes two pressure rollers, which rotate around the central axis when subjected to force. The present application adds a pressure roller assembly 26. After the cutting device 4 is started, the pressure roller assembly 26 is the first component to contact the sealing strip 40. The pressure roller assembly 26 can further act on the sealing strip 40. If the sealing strip 40 is partially warped, the pressure roller assembly 26 will apply force to the warped part to ensure that the sealing strip 40 has been fully installed to cooperate with the subsequent cutting process.

[0077] The contact surfaces of the top profiling block 19, the inner profiling block 20 and the sealing strip 40, and the contact surfaces of the insert 30 and the sealing strip 40 are all provided with anti-wear coatings, and the anti-wear coatings are made of Teflon material. The anti-wear coatings made of Teflon can effectively prevent the top profiling block 19 and the inner profiling block 20 from scratching the surface of the sealing strip 40 when they are in contact with the sealing strip 40.

[0078] The present application also includes a control device 27. A sensor 28 for sensing whether a sealing strip 40 is installed on the mounting seat 3 is provided at one end of the mounting seat 3 close to the cutting device 4. The sensor 28 is electrically connected to the control device 27. In the present application, various power devices are electrically connected to the control device 27. The power device includes a lifting device 7, a rotary pressing cylinder 10, a double-stroke cylinder 15, etc.

The description of the above embodiments is only used to help understand the present application and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
