Description

TECHNICAL FIELD

[0001] The application relates to the production and processing technology field of sealing strips, in particular to a servo cutting automatic punching device for the upper end of a sealing strip top strip. BACKGROUND

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

[0003] Early sealing strip cutting usually requires fixing the sealing strip at multiple positions, manually operating a blade to cut the surface of the sealing strip, and then removing the excess waste. This cutting method is not only complex, but also difficult to ensure that the size of the sealing strip after cutting is the same due to manual intervention, which affects the sealing of the automobile.

[0004] Some automatic cutting devices have appeared on the market, such as Chinese patent application "Automobile sealing strip cutting device", application number: CN202222448703.3; which discloses a support assembly, a cutting assembly, a clamping assembly and a sliding assembly. The support assembly includes a base, the base is provided with a vertical plate, and the top of the two vertical plates is provided with a top plate; the cutting assembly includes a mounting plate, the mounting plate is provided with a cutter seat, and the cutter seat is provided with a cutting blade; the clamping assembly includes a support plate, the support plate is provided with a support block, the support block is provided with a cylinder fixing plate, the cylinder fixing plate is provided with a waste clamping cylinder and a finished product clamping cylinder, the waste clamping cylinder and the finished product clamping cylinder are arranged on the two sides of the cutting blade, and the extension end of the waste clamping cylinder and the extension end of the finished product clamping cylinder are in abutment with the product; the sliding assembly includes a linear module, and the linear module is arranged on the base and connected with the support plate. The automobile sealing strip cutting can be automatically completed, and the accuracy of the cutting size can be ensured, the size of the sealing strip after cutting can be ensured, and the sealing property of the sealing strip can be improved.

[0005] However, the existing sealing strip cutting technology has some deficiencies, especially in terms of accuracy and automation. The sealing strip top strip structure involved in the application is as follows: Figure 1As shown, the sealing strip has a large overall length and a soft structure, and the sealing strip is easy to deform under stress, and therefore, when the sealing strip 40 is processed to cut a long and narrow notch 41, the processing blade needs to be cut along the length direction of the sealing strip, and it is difficult to ensure the accuracy of the product. In view of the technical problems existing in the cutting process of the sealing strip, a high-precision automatic punching device is developed, which can effectively improve the production efficiency and quality of the sealing strip, and meet the high standard requirements of modern automobile industry on the sealing strip. Content of the utility model

[0006] The technical problem to be solved by the present application is to provide a sealing strip top strip upper end servo cutting automatic punching device, which improves the processing accuracy and production efficiency of the sealing strip, reduces manual operation and reduces human errors by optimizing the design of the cutting device.

[0007] The technical scheme adopted by the present application is: a sealing strip top strip upper end servo cutting automatic punching device, comprising a rack, wherein the rack is provided with a sliding rail and a mounting seat for mounting a sealing strip, a cutting device is mounted on the sliding rail, the cutting device comprises a profiling assembly and a cutting knife group,

[0008] The profiling assembly comprises a profiling seat and at least one profiling block mounted on the profiling seat, and the end face of the profiling block is in contact with the surface of the sealing strip,

[0009] The cutting knife group comprises a double-stroke cylinder and a knife seat, and a cutting blade and a cutting-off blade are respectively mounted on the knife seat, the double-stroke cylinder is connected with the cutting blade and the cutting-off blade, and the double-stroke cylinder drives the cutting blade or the cutting-off blade to move downward for cutting or to rise for knife retraction,

[0010] The knife seat is mounted on the profiling seat, and the cutting device moves along the sliding rail to cut the sealing strip on the mounting seat.

[0011] Compared with the prior art, the present application has the following advantages: first, by combining the sliding rail and the cutting device, the automatic cutting of the sealing strip is realized, and the need for manual operation is reduced. This not only improves the production efficiency, but also reduces the possibility of human error. Second, by providing the double-stroke cylinder and the knife seat, the movement stroke of the cutting blade and the cutting-off blade is accurately controllable, which can ensure the consistency of the length and angle of each cutting, thereby improving the processing accuracy of the sealing strip. Third, the design of the profiling assembly enables the present application to be in contact with the outer surface of the sealing strip during cutting, thereby limiting the deformation of the sealing strip during cutting and ensuring the accuracy of cutting, further improving the processing accuracy of the sealing strip. The introduction of the automatic punching device makes the entire processing process of the sealing strip more smooth, and more processing tasks can be completed in a shorter time, thereby improving the overall production efficiency.

[0012] In some embodiments of the present application, the profiling seat is respectively provided with a top profiling block, an inner profiling block and an outer block, 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 near one side of the slide rail; when the profiling assembly moves to the position of the sealing strip, the top profiling block is in contact with the top surface of the sealing strip, and the end of the inner profiling block is embedded in one side surface of the sealing strip.

[0013] The top profiling block, the inner profiling block and the top surface and one side surface structure of the sealing strip are adapted to each other, which can ensure perfect fitting with the sealing strip during cutting, reduce errors during cutting and improve cutting accuracy.

[0014] Through the design of the top profiling block and the inner profiling block, the deformation of the sealing strip during cutting can be limited, the accuracy of cutting can be ensured, and the product quality can be improved.

[0015] In some embodiments of the present application, a plurality of rollers are installed below the outer block through a rotating shaft; when the profiling assembly moves to the position of the sealing strip, the outer circumferential surface of the roller is attached to the other side surface of the sealing strip away from the slide rail; when the profiling assembly moves, the roller rotates around the rotating shaft under the action of the friction force applied by the sealing strip.

[0016] The design of the roller can effectively attach to the outer side surface of the sealing strip, provide additional support, enhance the stability of the sealing strip during cutting, and reduce its displacement during processing. The rotation of the roller can reduce the frictional resistance between the roller and the surface of the sealing strip, so that the profiling assembly moves more smoothly, reduces damage to the surface of the sealing strip, and protects the integrity of the sealing strip. By applying uniform pressure to the outer side of the sealing strip, the roller can ensure that the position of the sealing strip does not change during cutting, thereby improving the accuracy and consistency of cutting.

[0017] In some embodiments of the present application, a predetermined gap exists between the top profiling block and the inner profiling block for the lip of the sealing strip to be cut to extend into.

[0018] The design of the predetermined gap allows the lip of the sealing strip to extend accurately, ensuring accurate alignment during cutting and improving cutting accuracy. By setting the gap, interference of other parts of the sealing strip with the lip to be cut can be avoided, ensuring smooth cutting and avoiding cutting to other positions of the sealing strip. The extension design of the lip can increase the stability of the sealing strip during cutting, reduce deformation or displacement caused by cutting, and ensure the accuracy of cutting.

[0019] In some embodiments of the present application, the profiling seat is provided with a mounting groove, the cutter seat bottom is embedded into the mounting groove and connected with the profiling seat, the side face of the top profiling block close to the cutter seat is referred to as the first side face of the top profiling block, the first side face is an inclined face and parallel to the cutting face of the sealing strip lip, and one side face of the cutting blade and one side face of the scribing blade are arranged in abutment with the first side face of the top profiling block.

[0020] The cutter seat bottom is embedded into the mounting groove, providing stable connection and ensuring the relative position of the cutter and the profiling seat, so that displacement does not occur during cutting, thereby improving the cutting precision. The cutting blade and the scribing blade are in abutment with the first side face of the top profiling block, ensuring the stability of the blade during cutting and further improving the cutting precision and consistency. The inclined face design can ensure the precision of the sealing strip lip cutting face angle.

[0021] In some embodiments of the present application, the top face of the inner profiling block is provided with a waste groove, the waste groove penetrates through one end face of the inner profiling block, one side inner wall face of the waste groove is referred to as the first side face of the waste groove, and the first side face of the waste groove is located in the same plane as the first side face of the top profiling block; the sealing strip lip extending between the top profiling block and the inner profiling block is scribed and separated from the waste material by the scribing blade, and the waste material is cut off by the cutting blade and then falls into the waste groove and is discharged.

[0022] That is, when the cutting blade or the scribing blade moves up and down (switches between cutting or work-off state), it is always in abutment with the first side face of the top profiling block and / or the first side face of the waste groove, which can effectively ensure the stability and reliability of the movement of the cutting blade and the scribing blade, thereby improving the scribing precision. The waste groove effectively avoids the influence of waste material generated during cutting on the sealing strip, and effectively isolates the two.

[0023] In some embodiments of the present application, the end face of the top profiling block close to the sealing strip and the end face of the inner profiling block close to the sealing strip are provided as rounded tips.

[0024] The above structure allows the top profiling block and the inner profiling block to be smoothly inserted into each gap of the outer surface of the sealing strip, ensuring sufficient abutment with the outer surface of the sealing strip.

[0025] In some embodiments of the present application, the profiling seat is further provided with an insert at the end close to the sealing strip, one end of the insert constitutes an outer profiling block, the outer profiling block is adapted to the structure of the side of the sealing strip away from the slide rail; when the profiling assembly moves to the sealing strip, the lower bottom face of the insert acts on the top face of the sealing strip, and the outer profiling block is embedded into the other side face of the sealing strip to expand the structure of the other side face of the sealing strip, and the outer profiling block is located in front of the roller.

[0026] That is, the structure of the other side of the sealing strip is regularized by the outside profiling block, and then the roller is embedded.

[0027] In some embodiments of the present application, the insert is further provided with a pressure roller assembly near one end of the sealing strip, the pressure roller assembly is located above the sealing strip, and the pressure roller assembly comprises two pressure rollers which rotate around a central axis under force.

[0028] The present application adds a pressure roller assembly, which is the first component to contact the sealing strip after the cutting device is started. The pressure roller assembly can further act on the sealing strip. If the sealing strip is locally warped, the pressure roller assembly will apply force to the warped part to ensure that the sealing strip has been fully installed and cooperates with subsequent cutting processing.

[0029] In some embodiments of the present application, an anti-wear coating is provided on the contact surface of the top profiling block, the inner side profiling block, and the contact surface of the insert contacting the sealing strip, and the anti-wear coating is made of Teflon material.

[0041] The present application will now be described in detail with reference to the accompanying drawings.

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0043] Automatic punching and serpentine cutting equipment for the upper end of the sealing strip top, as shown in Example 1. Figures 1 to 2 As shown: It includes a frame 1, on which a slide rail 2 and a mounting base 3 for mounting a sealing strip 40 are provided. A slicing device 4 is mounted on the slide rail 2. The slicing device 4 includes a contouring component 13 and a slicing blade assembly 14. The contouring component 13 includes a contouring seat 29 and at least one contouring block mounted on the contouring seat 29. The end face of the contouring block contacts the surface of the sealing strip 40. The design of the contouring component 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 precision of the sealing strip 40.

[0044] The slicing blade assembly 14 includes a double-stroke cylinder 15 and a blade holder 16. The blade holder 16 is equipped with a slicing blade 17 and a cutting blade 18. The double-stroke cylinder 15 is connected to the slicing blade 17 and the cutting blade 18. When the double-stroke cylinder 15 is working, it drives the slicing blade 17 or the cutting blade 18 to move down to cut or to rise back to retract the blade. By setting the double-stroke cylinder 15 and the blade holder 16, the movement stroke of the slicing blade 17 and the cutting blade 18 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 40.

[0045] The cutter holder 16 is mounted on the contour base 29, and the slicing device 4 moves along the slide rail 2 to cut the sealing strip 40 on the mounting base 3. The combination of the slide rail 2 and the slicing device 4 enables automatic slicing of the sealing strip 40, reducing the need for manual operation. This not only improves production efficiency but also reduces the possibility of human error. The introduction of the semi-automatic punching equipment makes the entire processing of the sealing strip 40 smoother, enabling more processing tasks to be completed in a shorter time, thereby improving overall production efficiency.

[0046] Example 2, as Figures 2 to 7 As shown, the contouring base 29 is equipped with a top contouring block 19, an inner contouring block 20, and an outer contouring block 21. The bottom structure of the top contouring block 19 is adapted to the top structure of the sealing strip 40, and the end of the inner contouring block 20 is adapted to the structure of the sealing strip 40 near the slide rail 2. When the contouring assembly 13 moves to the location of the sealing strip 40, the top contouring block 19 acts on the top surface of the sealing strip 40 and contacts the top surface of the sealing strip 40, and the end of the inner contouring block 20 is embedded in one side of the sealing strip 40 and contacts one side of the sealing strip 40.

[0047] The top contour block 19 and the inner contour block 20 are adapted to the top surface and one side surface of the sealing strip 40, ensuring a perfect fit with the sealing strip 40 during cutting, reducing cutting errors and improving cutting accuracy. The design of the top contour block 19 and the inner contour block 20 limits the deformation of the sealing strip 40 during cutting, ensuring cutting accuracy and improving product quality.

[0048] Several rollers 24 are mounted below the outer block 21 via a rotating shaft; when the contouring component 13 moves to the location of the sealing strip 40, the outer circumferential surface of the rollers 24 is in contact with the other side of the sealing strip 40 away from the slide rail 2; when the contouring component 13 moves, the rollers 24 rotate around the rotating shaft under the action of the friction force applied by the sealing strip 40.

[0049] The roller 24 is designed to effectively conform to the outer surface of the sealing strip 40, providing additional support, enhancing the stability of the sealing strip 40 during cutting, and reducing its displacement during processing. The rotation of the roller 24 reduces frictional resistance between itself and the surface of the sealing strip 40, allowing the contouring assembly 13 to move more smoothly, reducing damage to the surface of the sealing strip 40, and protecting its integrity. By applying uniform pressure to the outer side of the sealing strip 40, the roller 24 ensures that the position of the sealing strip 40 remains unchanged during cutting, thereby improving cutting accuracy and consistency.

[0050] The predetermined gap between the top profiling block 19 and the inner profiling block 20 is designed to allow the lip of the seal strip 40 to extend into it. The design of the predetermined gap allows the lip of the seal strip 40 to extend accurately, ensuring accurate alignment during cutting and improving cutting accuracy. By setting the gap, interference of other parts of the seal strip 40 with the lip to be cut can be avoided, ensuring smooth cutting and avoiding cutting into other parts of the seal strip 40. The design of the lip extension can increase the stability of the seal strip 40 during cutting, reduce deformation or displacement caused by cutting, and ensure cutting accuracy.

[0051] The profiling seat 29 is provided with a mounting groove, and the bottom of the tool seat 16 is embedded in the mounting groove and connected with the profiling seat 29. The side of the top profiling block 19 close to the tool seat 16 is referred to as the first side of the top profiling block 19, which is an inclined surface parallel to the cutting surface of the lip of the seal strip 40. One side of the cutting blade 18 and one side of the scoring blade 17 are arranged in close contact with the first side of the top profiling block 19. The bottom of the tool seat 16 is embedded in the mounting groove, providing stable connection and ensuring the relative position of the tool and the profiling seat 29, so that displacement does not occur during cutting, thereby improving cutting accuracy. The cutting blade 18 and the scoring blade 17 are in close contact with the first side of the top profiling block 19, ensuring the stability of the blades during cutting and further improving cutting accuracy and consistency. The design of the inclined surface ensures the accuracy of the angle of the cutting surface of the lip of the seal strip 40.

[0052] The top surface of the inner profiling block 20 is provided with a waste groove 25, and the waste groove 25 penetrates one end surface of the inner profiling block 20. One side inner wall surface of the waste groove 25 is referred to as the first side of the waste groove 25, and the first side of the waste groove 25 is located in the same plane as the first side of the top profiling block 19. The lip of the seal strip 40 extending between the top profiling block 19 and the inner profiling block 20 is cut and separated by the scoring blade 17, and the waste is cut off by the cutting blade 18, and then falls into the waste groove 25 and is discharged. That is, when the cutting blade 18 or the scoring blade 17 moves up and down (switches between cutting and non-cutting states), it is always in close contact with the first side of the top profiling block 19 and / or the first side of the waste groove 25, which can effectively ensure the stability and reliability of the movement of the cutting blade 18 and the scoring blade 17, thereby improving the cutting accuracy. The design of the waste groove 25 effectively avoids the influence of the waste generated during cutting on the seal strip 40, and effectively isolates the two.

[0053] The end surface of the top profiling block 19 close to the seal strip 40 and the end surface of the inner profiling block 20 close to the seal strip 40 are designed as 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 seal strip 40, ensuring full contact with the outer surface of the seal strip 40.

[0054] The profiling seat 29 is further provided with an insert 30 near one end of the sealing strip 40, one end of the insert 30 constituting an outer profiling block, which is adapted to the structure of the other side of the sealing strip 40 away from the slide rail 2; when the profiling assembly 13 moves to the position 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 into the other side surface of the sealing strip 40 to expand the structure of the other side surface of the sealing strip 40, and the outer profiling block is located in front of the roller 24. That is, the structure of the other side surface of the sealing strip 40 is expanded by the outer profiling block, and then the roller 24 is embedded.

[0055] The insert 30 is further provided with a compression roller assembly 26 near one end of the sealing strip 40, and the compression roller assembly 26 is located above the sealing strip 40, and the compression roller assembly 26 includes two compression rollers, which rotate around the central axis under stress. The compression roller assembly 26 is the first component to contact the sealing strip 40 after the cutting device 4 is started, and the compression roller assembly 26 can further act on the sealing strip 40. If the sealing strip 40 is locally warped, the compression roller assembly 26 will press the warped part to ensure that the sealing strip 40 has been fully installed and cooperates with subsequent cutting processing.

[0056] The top profiling block 19, the inner profiling block 20, the contact surface of the sealing strip 40, and the contact surface of the insert 40 are all provided with an anti-wear coating made of Teflon material. The anti-wear coating made of Teflon can effectively prevent the top profiling block 19 and the inner profiling block 20 from causing scratches on the surface of the sealing strip 40 when they contact the sealing strip 40.

[0057] The other contents of the second embodiment are the same as those of the first embodiment.
