Description

Technical Field

[0001] This application relates to the field of automotive sealing strip processing technology, and in particular to a dual-station automatic punching and cutting device for automotive sealing strips. Background Technology

[0002] Automotive sealing strips, as a key component of the vehicle body sealing system, are widely used in doors, windows, sunroofs, and other parts. Their ends often require complex punching at multiple angles and positions (such as beveling and dovetail cutting) to meet requirements for sealing performance, aesthetics, and installation compatibility. Traditional sealing strip punching processes mainly rely on single-station punching equipment, processing the sealing strip sequentially using a single die. However, with the advancement of automotive lightweighting and modular design trends, the structural complexity of sealing strips has significantly increased, exposing the following technical bottlenecks in single-station equipment:

[0003] First, the process efficiency is low: complex end punching requires multiple independent punching actions to be completed in sequence (such as oblique cuts and irregular cuts at different angles). Single-station equipment requires repeated mold replacements or adjustments to positioning devices, which leads to a longer production cycle and makes it difficult to meet the needs of large-scale production.

[0004] Secondly, the accuracy and consistency are poor: repeated clamping can easily introduce cumulative positioning errors. Especially for flexible sealing strip materials, frequent manual intervention in the process can easily lead to the cutting shape and position tolerances exceeding the limit, affecting the assembly quality.

[0005] Third, the equipment has functional limitations: the single-station structure makes it difficult to integrate multiple die-cutting operations. When facing multi-position and multi-dimensional punching tasks, it is often necessary to configure auxiliary equipment or manually handle post-processing, which increases the complexity and cost of the production line.

[0006] To address the aforementioned issues, there is an urgent need to develop a dual-station automatic punching device specifically designed for automotive sealing strips. Through collaborative station design, this device can meet the automotive industry's demand for efficient, precise, and automated processing of sealing strips. Utility Model Content

[0007] In order to overcome the problems existing in the prior art, this application provides a dual-station automatic punching device for automotive sealing strips.

[0008] The dual-station automatic punching and cutting equipment for automotive sealing strips provided in this application adopts the following technical solution:

[0009] A dual-station automatic punching device for automotive sealing strips includes a frame and punching sections, clamping sections, and material handling sections mounted on the frame. The frame includes a frame body and slide rails distributed along its length within the frame body. The frame body has protective netting on its sides and a lighting lamp installed at the top center. Two sets of punching sections are provided, each moving along one of the slide rails. A clamping section is installed at the center of each slide rail. Each punching section includes a first punching mechanism and a second punching mechanism on either side of the clamping station. Both mechanisms have several punching positions, which are coordinated by servo motors to perform multi-position asynchronous or synchronous punching. Both the first and second punching mechanisms are detachably mounted on sliding seats, which are slidably mounted on the slide rails. The clamping section is used to clamp the automotive sealing strip to be punched. The seal moves between two sets of punching sections driven by a servo motor, including a fixed base and a clamping body. The fixed base is fixed to the frame, and the clamping body slides along the length of the fixed base. The clamping body is driven by a moving cylinder at the bottom of the fixed base. The material handling section is located on the back of the clamping mechanism near the frame, including a gripper and a lifting mechanism that drives the gripper to rise and fall. The gripper includes a gripper frame and a gripper body located at the bottom of the gripper. The gripper body corresponds to the automotive sealing strip held on the clamping body. The gripper body includes a gripper cylinder and an upper gripper and a lower gripper installed at the output end of the gripper cylinder. The lifting mechanism includes a lifting motion module and a lifting motor that drives the gripper body to rise and fall on the lifting motion module. The lead screw at the output end of the lifting motor drives the lead sleeve on the gripper body to control the rise and fall of the gripper body.

[0010] By adopting the above technical solution, the moving cylinder of the clamping part drives the clamping body to slide along the fixed base, clamping and transporting the automotive sealing strip to be punched to a set of punching parts on the outside of the frame. The first and second punching mechanisms located on the slide rail move to the corresponding positions along the slide rail under the drive of the sliding seat. Several sets of punching cutters on them perform punching operations on the sealing strip. After the punching of this set of workstations is completed, the clamping body in the clamping part moves the automotive sealing strip to a set of punching parts on the inside of the frame under the action of the moving cylinder. The first and second punching mechanisms, located on the slide rails on both sides, move to their corresponding positions along the slide rails under the drive of the sliding seat. Several sets of punching cutters on them perform punching operations on the sealing strip. After the automotive sealing strip is punched, the lifting motor of the material picking part drives the claw to descend along the lifting motion module. The gripper cylinder at the bottom of the claw frame drives the upper and lower grippers to close, clamping the punched sealing strip. Then, the lifting motor lifts it out. The whole process realizes the automation and efficient dual-station operation of automotive sealing strip punching.

[0011] Preferably, the first punching mechanism includes a punching body and a guide punching seat, and the second punching mechanism includes a punching body and two sets of guide punching seats, wherein the automotive sealing strip passes through the guide punching seat and the punching body, and each of them is provided with at least one set of punching positions, the punching position including a punching cylinder and a cutter located at the output end of the punching cylinder.

[0012] Preferably, the first and second punching mechanisms are equipped with at least one set of alcohol spraying mechanisms, each including a mounting bracket and an alcohol nozzle, wherein the alcohol nozzle is connected to an external alcohol supply mechanism via a pipeline.

[0013] Preferably, a waste collection pipe is also installed at the bottom of the guide punching seat and the punching body. The top opening of the waste collection pipe is located below the punching position, and a waste collection box can be placed below the bottom opening. The top opening of the waste collection pipe is larger than the bottom opening.

[0014] Preferably, the feeding ends of the punching body and the guide punching seat are provided with trumpet-shaped openings, and the cutters in the punching position are all slidably installed in the limiting seat.

[0015] Preferably, the first punching mechanism on the punching part near the material receiving part is also equipped with an automotive sealing strip adjustment mechanism, including an adjustment base and an adjustment block. The adjustment base is fixedly installed on the frame, and the adjustment block is driven by an adjustment cylinder on its top, and the two form a space to accommodate the automotive sealing strip.

[0016] By adopting the above technical solution, the clamping part feeds the sealing strip into the first and second punching mechanisms. The automotive sealing strip passes through the punching position of the guide punching seat and the punching body. The flared openings at the feeding ends of the punching body and the guide punching seat facilitate the introduction of the automotive sealing strip. The punching cylinder drives the cutter to slide along the limiting seat to complete the punching action. The first punching mechanism includes one guide punching seat, and the second punching mechanism is equipped with two, ensuring stable positioning and precise punching of the sealing strip. The alcohol spraying mechanism sprays alcohol onto the punching position before punching through nozzles on the mounting bracket. The alcohol is supplied by an external supply mechanism, which serves as a lubricant and cleaner, improving the punching quality. The waste generated during punching falls into the collection box below through the waste collection pipe (the design with a large opening at the top and a small opening at the bottom facilitates waste collection) at the bottom of the guide punching seat and the punching body. Because the automotive sealing strips on a set of punching sections near the outer side of the frame can be manually guided, while the first punching mechanism near the material handling station is on the side away from the operator, manual adjustment is inconvenient. Therefore, the position and tightness of the automotive sealing strips can be adjusted by adjusting the cylinder to drive the adjusting block, and with the cooperation of the adjusting base, the punching accuracy and finished product quality can be guaranteed.

[0017] Preferably, a slider adapted to the slide rail is fixedly installed at the bottom of the sliding seat. The top surface of the sliding seat includes limiting blocks on both sides and a locking block on one side. The inner side of the limiting block abuts against the inner side of the punching part. The locking block has a downward inclined surface on the side facing the punching part. A locking rotating rod is provided on the side of the sliding seat away from the locking block. The base of the punching part has inclined surfaces and locking grooves corresponding to the limiting block and the locking rotating rod, respectively.

[0018] By adopting the above technical solution, the sliding seat is installed by adapting to the frame slide rail via a slider at the bottom, realizing the sliding function along the slide rail. The sliding seat can move on the slide rail via an external drive device, which can be a cylinder. When installing the punching part, align its base with the sliding seat, and use the inner side of the limiting block to tightly abut against the inner side of the punching part for initial positioning; at the same time, the downward inclined surface on the snap-fit ​​block fits against the corresponding inclined surface of the punching part base, facilitating quick docking between the two. After the punching part is in place, rotate the locking rotating rod on the sliding seat to make it snap into the locking groove of the punching part base, and then lock and fix the locking rotating rod to form a stable locking structure, thereby reliably fixing the punching part to the sliding seat; when disassembling, contact the locking rotating rod in the locked state, rotate the locking rotating rod in the opposite direction to release the lock, and the punching part can be easily removed, realizing quick disassembly and assembly and stable fixation of the punching part on the sliding seat.

[0019] Preferably, the clamping body includes two sets of clamping plates symmetrically distributed, the clamping plates are rotatably connected to the mounting plate on their outer side, and a sealing strip placement plate is provided on the outer side of the mounting plate. The clamping plates rotate under the drive of the clamping cylinder at the bottom center of the clamping body to clamp the sealing strip on the sealing strip placement plate.

[0020] Preferably, the drive block installed on the output end of the clamping cylinder cooperates with the groove below the clamping plate for transmission. The two ends of the drive block are rotatably connected to the inner wall of the groove of the clamping plate through a rotating plate. The drive block is provided with limiting plates on both sides for limiting the drive block. The through hole on the drive block corresponds to the strip-shaped through hole on the limiting plate.

[0021] By adopting the above technical solution, when it is necessary to clamp the automotive sealing strip, the clamping cylinder at the center of the bottom of the clamping body is activated. The drive block at the output end of the clamping cylinder moves under the action of power. The rotating plates at both ends of the drive block are rotatably connected to the inner wall of the groove below the clamping plate. This connection method allows the movement of the drive block to drive the clamping plate to rotate. During the movement of the drive block, the strip-shaped perforations on the limit plates on both sides cooperate with the connecting rods set in the through holes on the drive block to limit the range and direction of movement of the drive block and ensure stable transmission of the drive block. The two symmetrically distributed clamping plates rotate synchronously under the drive of the drive block, gradually approaching the sealing strip on the sealing strip placement plate and completing the clamping. When it is necessary to release the sealing strip, the clamping cylinder is driven in the opposite direction, and the drive block drives the clamping plate to rotate in the opposite direction, thereby releasing the sealing strip, realizing reliable clamping and releasing operations for the automotive sealing strip.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application sets two sets of punching parts in the device, both of which can move on the slide rail. With the clamping part located in the center of the slide rail, dual-station collaborative operation can be realized. Compared with traditional single-station equipment, which requires repeated mold changes or adjustment of positioning devices to complete multiple independent actions of complex end punching, this device can perform processing operations such as oblique cutting at different angles and irregular cutting at the same time without frequent mold switching, which greatly shortens the production cycle and meets the high-efficiency requirements of large-scale production of automotive sealing strips.

[0024] 2. The clamping part of this application, through a fixed base and a clamping body that can slide along its length, and driven by a moving cylinder, can accurately clamp the automotive sealing strip to be punched and stably move between two sets of punching parts driven by a servo motor. At the same time, the grippers and lifting mechanism of the material picking part cooperate precisely, reducing manual intervention and avoiding the cumulative positioning error introduced by repeated clamping. Especially for flexible sealing strip materials, it effectively controls the cutting form and position tolerance and ensures high precision and consistency of assembly quality.

[0025] 3. The first and second punching mechanisms in this application are provided with different numbers of guide punching seats and punching positions, which can integrate multiple die-cutting machines to work together, meet multi-position and multi-dimensional punching tasks, and eliminate the need for additional auxiliary equipment or manual post-processing, simplifying the complexity of the production line. At the same time, the punching parts can be detachably installed on the sliding seat, which makes it convenient to replace or adjust the punching mechanism according to different sealing strip punching requirements, enhance the versatility of the equipment, and reduce the cost of equipment use and maintenance.

[0026] 4. The alcohol spraying mechanism installed on the first and second punching mechanisms in this application allows alcohol to be sprayed through the alcohol nozzle during the punching process, which serves to lubricate and cool the material, reduce friction between the cutter and the sealing strip, lower the punching temperature, prevent the sealing strip material from deforming due to high temperature, and improve the punching quality and cut smoothness. The waste collection pipe installed at the bottom of the guide punching seat and the punching body has a large opening at the top and a small opening at the bottom, which facilitates the collection of waste generated during punching, keeps the working environment clean, and avoids waste accumulation affecting equipment operation. The trumpet-shaped opening at the feed end of the punching body and the guide punching seat facilitates the smooth introduction of the automotive sealing strip into the punching position, and the cutter is correspondingly slidably installed in the limit seat to ensure the stability and accuracy of the punching action.

[0027] 5. The slider at the bottom of the sliding seat in this application is adapted to the slide rail, which facilitates the movement and positioning of the punching part. The limiting block, snap-fit ​​block, and locking rotating rod on its top surface cooperate with the corresponding structure on the base of the punching part to realize the quick installation and disassembly of the punching part, which facilitates equipment debugging and maintenance. The two sets of clamping plates of the clamping body rotate under the drive of the clamping cylinder to clamp the sealing strip. With the help of the drive block, rotating plate, limiting plate and other structures, the sealing strip is firmly and stably clamped. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0039] This application discloses a dual-station automatic punching and cutting device for automotive sealing strips.

[0040] Reference Figures 1-9A dual-station automatic punching device for automotive sealing strips includes a frame 1 and punching sections 2, clamping sections 3, and a material handling section 4 mounted on the frame 1. The frame 1 includes a frame body and slide rails 11 distributed along its length within the frame body. A protective net 12 is provided on the side of the frame body, and a lighting lamp 13 is installed at the top center. The punching sections 2 are provided in two sets and move on the slide rails 11 respectively. A clamping section 3 is installed at the center of the slide rails 11. The punching sections 2 include a first punching mechanism 21 and a second punching mechanism 22 on both sides of the clamping station. Both mechanisms have several sets of punching positions 213. The punching positions 213 cooperate with servo motors to complete multi-position asynchronous or synchronous punching. Both the first punching mechanism 21 and the second punching mechanism 22 can be detachably mounted on a sliding seat 23, which is slidably mounted on the slide rails 11. The clamping section 3 is used to clamp the automotive sealing strip to be punched and move it between the two sets of punching sections 2. The clamping mechanism includes a fixed base 31 and a clamping body 32. The fixed base 31 is fixed on the frame 1, and the clamping body 32 slides along the length of the fixed base 31. The clamping body 32 is driven by a moving cylinder 33 at the bottom of the fixed base 31. The material handling part 4 is located on the back of the clamping mechanism near the frame 1 and includes a gripper 41 and a lifting mechanism 42 for driving the gripper 41 to rise and fall. The gripper 41 includes a gripper frame 411 and a gripper body 412 located at the bottom of the gripper. The gripper body 412 corresponds to the automotive sealing strip held on the clamping body 32. The gripper body 412 includes a gripper cylinder and an upper gripper 4122 and a lower gripper 4123 installed at the output end of the gripper cylinder. The lifting mechanism 42 includes a lifting motion module 421 and a lifting motor 422 for driving the gripper body 412 to rise and fall on the lifting motion module 421. The lead screw at the output end of the lifting motor 422 drives the lead sleeve on the gripper body 412 to control the rise and fall of the gripper body 412.The moving cylinder 33 of clamping part 3 drives the clamping body 32 to slide along the fixed base 31, clamping and transporting the automotive sealing strip to be punched to a set of punching parts 2 on the outside of the frame 1. The first punching mechanism 21 and the second punching mechanism 22 located on the slide rail 11 move to the corresponding positions under the drive of the sliding seat 23. Several sets of punching blades 2132 on them perform punching operations on the sealing strip. After the punching of this set of workstations is completed, the clamping body 32 in clamping part 3 moves the automotive sealing strip to a set of punching parts 2 on the inside of the frame 1 under the action of the moving cylinder 33, which is also located on both sides of the slide rail. Driven by the sliding seat 23, the first punching mechanism 21 and the second punching mechanism 22 on the slide rail 11 move to the corresponding positions along the slide rail 11. Several sets of punching blades 2132 on them perform punching operations on the sealing strip. After the automotive sealing strip is punched, the lifting motor 422 of the material taking part 4 drives the claw body 412 to descend along the lifting motion module 421. The cylinder of the gripper 41 at the bottom of the claw frame 411 drives the upper gripper 4122 and the lower gripper 4123 to close, clamping the punched sealing strip. Then, the lifting motor 422 lifts it out. The whole process realizes the automation and efficient dual-station operation of automotive sealing strip punching.

[0041] Reference Figures 1-9The first punching mechanism 21 includes a punching body 211 and a guide punching seat 212. The second punching mechanism 22 includes a punching body 211 and two sets of guide punching seats 212. The automotive sealing strip passes through the guide punching seat 212 and the punching body 211, and each has at least one set of punching positions 213. The punching position 213 includes a punching cylinder 2131 and a cutter 2132 located at the output end of the punching cylinder 2131. The first punching mechanism 21 and the second punching mechanism 22 are equipped with at least one set of alcohol spraying mechanisms 24. The alcohol spraying mechanism 24 includes a mounting bracket 241 and an alcohol nozzle 242, wherein the alcohol nozzle 242 is connected to an external alcohol supply mechanism through a pipe. A waste collection pipe 25 is also installed at the bottom of the guide punching seat 212 and the punching body 211. The top opening of the waste collection pipe 25 is located below the punching position 213, and a waste collection box can be placed below the bottom opening. The top opening of the waste collection pipe 25 is larger than the bottom opening. The feeding end of the punching body 211 and the guide punching seat 212 has a trumpet-shaped opening, and the cutters 2132 in the punching position 213 are slidably installed in the limiting seat 2133. An automotive sealing strip adjustment mechanism 27 is also installed on the first punching mechanism 21 on the punching part 2 near the material taking part, including an adjustment base 271 and an adjustment pressure block 272. The adjustment base 271 is fixedly installed on the frame 1, and the adjustment pressure block 272 is driven by the adjustment cylinder 273 on its top, and a space for accommodating the automotive sealing strip is formed between the two. The clamping part 3 feeds the sealing strip into the first punching mechanism 21 and the second punching mechanism 22. The automotive sealing strip passes through the guide punching seat 212 and the punching position 213 of the punching body 211. The flared openings at the feed ends of the punching body 211 and the guide punching seat 212 facilitate the introduction of the automotive sealing strip. The punching cylinder 2131 drives the cutter 2132 to slide along the limiting seat 2133 to complete the punching action. The first punching mechanism 21 includes one guide punching seat 212, and the second punching mechanism 22 is equipped with two, ensuring stable positioning and precise punching of the sealing strip. The alcohol spraying mechanism 24 sprays alcohol onto the punching position 213 before punching through the nozzle on the mounting bracket 241. The alcohol is supplied by an external supply mechanism, which serves to lubricate and clean, improving the punching quality. The waste generated during punching falls into the collection box below through the waste collection pipe 25 (with a large opening at the top and a small opening at the bottom) at the bottom of the guide punching seat 212 and the punching body 211. Because the automotive sealing strips on a set of punching parts 2 near the outer side of the frame 1 can be manually guided, and the first punching mechanism 21 near the material handling station is far from the operator, manual adjustment is inconvenient. Therefore, the adjusting cylinder 273 drives the adjusting block 272, and with the cooperation of the adjusting base 27126, the position and tightness of the automotive sealing strips are adjusted to ensure punching accuracy and finished product quality.

[0042] Reference Figures 1-9The bottom of the sliding seat 23 is fixedly equipped with a slider 231 adapted to the slide rail 11. The top surface of the sliding seat 23 includes limiting blocks 232 on both sides and a locking block 233 on one side. The inner side of the limiting block 232 abuts against the inner side of the punching part 2. The locking block 233 has a downward inclined surface 261 on the side facing the punching part 2. The side of the sliding seat 23 away from the locking block 233 is provided with a locking rotating rod 234. The base 26 of the punching part 2 is provided with the inclined surface 261 and locking groove 262 corresponding to the limiting block 232 and the locking rotating rod 234, respectively. The sliding seat 23 is adapted to the slide rail 11 of the frame 1 through the slider 231 at the bottom, realizing the sliding function along the slide rail 11. The sliding seat 23 can move on the slide rail 11 by an external drive device, which can be a cylinder. When installing the punching part 2, align its base 26 with the sliding seat 23, and use the inner side of the limiting block 232 to tightly abut against the inner side of the punching part 2 for initial positioning; at the same time, the downward inclined surface 261 on the snap-fit ​​block 233 fits against the corresponding inclined surface 261 of the base 26 of the punching part 2, facilitating quick docking between the two. After the punching part 2 is in place, rotate the locking rotating rod 234 on the sliding seat 23 to make it snap into the locking groove 262 of the base 26 of the punching part 2, and then lock and fix the locking rotating rod 234 to form a stable locking structure, thereby reliably fixing the punching part 2 on the sliding seat 23; when disassembling, contact the locked and fixed state of the locking rotating rod 234, rotate the locking rotating rod 234 in the opposite direction to release the lock, and the punching part 2 can be easily removed, realizing quick disassembly and assembly and stable fixation of the punching part 2 on the sliding seat 23.

[0043] Reference Figures 1-9The clamping body 32 includes two symmetrically distributed clamping plates 321. The clamping plates 321 are rotatably connected to the mounting plate 322 on their outer side. A sealing strip placement plate 323 is provided on the outer side of the mounting plate 322. The clamping plates 321 rotate under the drive of the clamping cylinder 324 at the bottom center of the clamping body 32 to clamp the sealing strip on the sealing strip placement plate 323. The driving block 3241 installed on the output end of the clamping cylinder 324 cooperates with the groove 3211 below the clamping plate 321 for transmission. The two ends of the driving block 3241 are rotatably connected to the inner wall of the groove 3211 of the clamping plate 321 through rotating plates. Limiting plates 325 are provided on both sides of the driving block 3241 for limiting the position of the driving block 3241. The through hole 3242 on the driving block 3241 corresponds to the strip-shaped through hole 3251 on the limiting plate 325. When it is necessary to clamp the car sealing strip, the clamping cylinder 324 at the bottom center of the clamping body 32 is activated. The drive block 3241 at the output end of the clamping cylinder 324 moves under the action of power. The rotating plates at both ends of the drive block 3241 are rotatably connected to the inner wall of the groove 3211 below the clamping plate 321. This connection method allows the movement of the drive block 3241 to drive the clamping plate 321 to rotate. During the movement of the drive block 3241, the strip-shaped through holes 3251 on the limit plates 325 on both sides are connected to the connecting rods in the through holes 3242 on the drive block 3241 to limit the range and direction of movement of the drive block 3241 and ensure stable transmission of the drive block 3241. Two symmetrically distributed clamping plates 321 rotate synchronously under the drive of the drive block 3241, gradually approaching the sealing strip on the sealing strip placement plate 323 and completing the clamping; when it is necessary to release the sealing strip, the clamping cylinder 324 is driven in the opposite direction, and the drive block 3241 drives the clamping plates 321 to rotate in the opposite direction, thereby releasing the sealing strip and realizing reliable clamping and releasing operations of the automotive sealing strip.

[0044] Working principle: The car sealing strip is placed on the sealing strip placement plate 323 of the clamping body 32. The clamping cylinder 324 drives the clamping plate 321 to rotate and firmly clamp it. Then, driven by the moving cylinder 33 at the bottom of the fixed base 31, the clamping body 32 slides along the length direction of the fixed base 31 and transports the sealing strip between the two sets of punching parts 2. First, the automotive sealing strip to be punched is clamped and transported to a set of punching positions 2 on the outside of the frame 1. The first punching mechanism 21 and the second punching mechanism 22 located on the slide rail 11 move to the corresponding positions along the slide rail 11 under the drive of the sliding seat 23. Several sets of punching blades 2132 on them perform punching operations on the sealing strip. After the punching of this set of workstations is completed, the clamping body 32 in the clamping part 3 moves the automotive sealing strip to a set of punching positions 2 on the inside of the frame 1 under the action of the moving cylinder 33. Similarly, the first punching mechanism 21 and the second punching mechanism 22 located on the slide rail 11 on both sides move to the corresponding positions along the slide rail 11 under the drive of the sliding seat 23. Several sets of punching blades 2132 on them perform punching operations on the sealing strip. The punching cylinders 2131 on the first punching mechanism 21 and the second punching mechanism 22 drive the cutter 2132 to punch the sealing strip at multiple angles and positions. During the punching process, the alcohol spraying mechanism 24 sprays alcohol through the alcohol nozzle 242 to lubricate and cool the strip. The waste generated by punching falls into the waste collection box through the guide punching seat 212 and the waste collection pipe 25 at the bottom of the punching body 211. If the first punching mechanism 21 on the station near the material taking part detects that the position or condition of the sealing strip is not good, the adjusting cylinder 273 drives the adjusting pressure block 272 to adjust it. After punching is completed, the lifting motor 422 of the material taking part 4 drives the gripper 41 to descend. The gripper 41 cylinder drives the upper gripper 4122 and the lower gripper 4123 to clamp the processed sealing strip. Then the lifting motor 422 drives the gripper 41 to rise and take away the sealing strip. Throughout the process, the two sets of punching parts 2 move on the slide rail 11 via the sliding seat 23 to achieve dual-station collaborative operation. The detachable structure between the sliding seat 23 and the punching part 2 makes it easy to replace or adjust the punching mechanism according to different processing requirements.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
