Description

Technical Field

[0001] This invention relates to the field of wet friction plate production and processing technology, and in particular to a paper-based manual punching and assembly equipment. Background Technology

[0002] Paper-based assembly is a core preliminary process in the production of wet friction pads, which determines the final bonding strength and friction performance of the product. Its processing accuracy directly affects the service life and braking stability of the friction pads, playing a crucial role in the production of wet clutches and brakes in the automotive and construction machinery industries. This process requires precisely punching and bonding the annular paper base to the surface of the metal substrate according to the preset equal division positions. Punching deviations at each station will lead to problems such as edge lifting and hollowing during the subsequent bonding process, resulting in the scrapping of the entire batch of products. With the growth of personalized demands in the downstream equipment manufacturing industry, the production of wet friction pads is gradually showing the characteristics of flexible production with multiple specifications and small batches, which puts forward higher requirements for the positioning accuracy, changeover efficiency and ease of operation of paper-based punching and assembly equipment.

[0003] Currently, paper-based punching and assembly equipment on the market is mainly divided into two categories: simple manual punching tools and fully automatic CNC punching equipment. Simple manual punching tools consist of a punching cutter without a positioning structure and a fixed worktable. They rely entirely on the worker's experience to manually press and punch the base paper, and then manually position and assemble the punched paper base onto the surface of the friction plate substrate by visual observation. Fully automatic CNC punching equipment, on the other hand, uses a CNC system to control the robotic arm and punching head to complete the entire process of automatic feeding, punching, positioning, and assembly of the paper base. It is equipped with a complete automated loading and unloading mechanism. In addition, there are some manual punching equipment with basic positioning structures, but their structural design has not been specifically optimized for the processing characteristics of the annular paper base of wet friction plates.

[0004] These existing equipment suffer from systemic compatibility defects in the production scenarios of wet friction plates with multiple specifications and small batches. Simple manual tools lack professional positioning benchmarks, resulting in insufficient punching accuracy. Poor adhesion between paper base and substrate, uneven punching force easily causes paper base damage, and workers are prone to muscle strain and low production efficiency due to prolonged improper operating postures. Although fully automatic equipment has higher accuracy and efficiency, its purchase and maintenance costs are high, and changeover and debugging are time-consuming. The equipment utilization rate is extremely low during small-batch production. Manual equipment with basic positioning lacks a dedicated rotary equal-division positioning structure, and there are no standardized procedures for mold replacement and parameter calibration. At the same time, it does not meet the dust prevention and tooling storage requirements of the production site, and the safety protection measures are inadequate. Ultimately, this leads to high overall production costs, low product qualification rates, and difficulty in maintaining a stable production rhythm in the paper base assembly process. Summary of the Invention

[0005] The purpose of this invention is to provide a paper-based manual punching and assembly device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a paper-based manual punching and assembly equipment, including a frame support assembly, a quick mold adjustment assembly fixedly installed on the top of the frame support assembly, a manually triggered rotary positioning assembly provided on the top of the quick mold adjustment assembly, and a manual crank punching assembly fixedly installed on the outer side of the top of the frame support assembly, the manual crank punching assembly being positioned above the top of the rotary positioning assembly.

[0007] The manual crank punching assembly includes a top frame, which is fixedly installed on the top of the frame support assembly. The top frame is located outside the quick die adjustment assembly. A top plate is fixedly installed on the top of the top frame, and a mounting top frame is fixedly installed on the top of the top plate. A crank punching module is movably installed on the inner side of the mounting top frame, and the punching end of the crank punching module is positioned above the manually triggered rotary positioning assembly.

[0009] Furthermore, trays are fixedly installed in a linear arrangement at equal intervals within the frame body, and an inspection door is provided on the outside of the electrical enclosure.

[0010] Furthermore, caster frames are installed at the four corners of the bottom of the frame body, and swivel casters are rotatably connected to the inner side of the caster frames.

[0011] Furthermore, the crank punching module includes a mounting top seat, which is fixedly installed on the upper front side of the mounting top frame.

A lifting plate is fixedly installed through the top plate and the top frame at the bottom of the sliding rod. A punching die is installed at the bottom of the lifting plate by screws. A crank handle is rotatably connected to the upper side of one side of the mounting top seat. The inner side of the crank handle is connected to one side of the hinged rocker arm by a coupling. A manual handle is fixedly installed at the outer end of the crank handle. Pulling the manual handle rotates the crank handle, which in turn rotates the hinged rocker arm. The rotation of the hinged rocker arm pushes the sliding rod to move the lifting plate down, thus enabling the punching die to perform processing.

[0012] Furthermore, both ends of the lifting plate are fixedly connected to sliding support sleeves, and the inner side of the sliding support sleeve is slidably connected to a support guide shaft. The top of the support guide shaft is connected to the bottom of the top plate, and the bottom of the support guide shaft is connected to the top of the frame.

[0013] Furthermore, a control box is fixedly installed on the upper side of one side of the top frame. A PLC controller is provided inside the control box, and a display screen and control buttons are provided on the front of the PLC controller.

[0014] Furthermore, the rapid mold adjustment assembly includes a mounting base, which is installed on the top center of the machine frame body by screws. A guide rail is fixedly installed on the top of the mounting base. A lead screw is rotatably connected to the inner side of the guide rail. A slide is threadedly connected to the outer surface of the lead screw. The slide is movable on the top of the guide rail. The outer end of the lead screw passes through the guide rail.

[0015] Furthermore, an adjusting handle is fixedly installed at the outer end of the lead screw through the guide rail, and an accordion cover is provided on the outer side of the guide rail for dust protection.

[0016] Furthermore, the manually triggered rotary positioning assembly includes a gearbox, which is fixedly installed on the top of the slide. A drive motor is fixedly installed on the outside of the gearbox, and a transmission gear set is provided inside the gearbox. The output end of the drive motor is connected to the input end of the transmission gear set. A bearing plate is rotatably connected to the top of the gearbox, and a clamp positioning steel plate is detachably installed on the top of the bearing plate by screws.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] In this invention, by coordinating a manual crank punching assembly, a manually triggered rotary positioning assembly, and a rapid die adjustment assembly, the manual rotational force can be converted into a vertical punching force during use. This ensures uniform punching force, reduces paper base breakage, and simultaneously rotates the support plate at a preset angle, adjusting the center position of the die and support plate to improve the positional accuracy of paper base punching. This prevents misalignment between the paper base and the friction plate substrate, eliminating the need for subsequent manual correction processes, reducing additional production steps and labor input, and improving the processing efficiency and product qualification rate of a single batch. The rapid die adjustment assembly and basic electrical auxiliary components allow for quick replacement of the die and positioning steel plate, shortening the total time for changeover and debugging. Production count information is automatically saved, eliminating the need for manual statistics. Combined with the tooling storage space inside the frame and the dustproof structure on the outside of the guide rails, tooling loss and misuse are reduced, preventing paper base debris from entering the gaps between moving parts and reducing the frequency of daily equipment maintenance. The equipment has no complex automated mechanisms, which greatly reduces procurement and subsequent maintenance costs. Workers can control the punching process in real time and adjust their operations in a timely manner to avoid batch product scrapping. At the same time, it reduces the labor intensity of manual operation, improves the controllability of production rhythm, and meets the processing requirements of wet friction sheet paper base assembly process.

[0028] Example

[0029] Please see Figures 1 to 8In this embodiment of the invention, a paper-based manual punching and assembly device includes a frame support assembly 1, a quick mold adjustment assembly 2 is fixedly installed on the top of the frame support assembly 1, a manually triggered rotary positioning assembly 3 is provided on the top of the quick mold adjustment assembly 2, and a manual crank punching assembly 4 is fixedly installed on the outer side of the top of the frame support assembly 1. The manual crank punching assembly 4 is located above the top of the rotary positioning assembly.

[0030] The manual crank punching assembly 4 includes a top frame 41, which is fixedly mounted on the top of the frame support assembly 1. The top frame 41 is located outside the quick die adjustment assembly 2. A top plate 42 is fixedly mounted on the top of the top frame 41, and a mounting top frame 43 is fixedly mounted on the top of the top plate 42. A crank punching module 44 is movably mounted on the inner side of the mounting top frame 43. The punching end of the crank punching module 44 is positioned above the manually triggered rotary positioning assembly 3. By setting the frame support assembly 1, the quick die adjustment assembly 2, the manually triggered rotary positioning assembly 3, and the manual crank punching assembly 4 to work together, the frame support assembly 1 can be used to support the overall structure during use. Provides stable load bearing. The quick mold adjustment component 2 can work with the manually triggered rotary positioning component 3 to complete position matching. The manual crank punching component 4 forms a stable support structure with the top frame 41, top plate 42 and mounting top frame 43. The crank punching module 44 can complete the movement inside the mounting top frame 43, and then perform punching operation on the material on the manually triggered rotary positioning component 3. Through the layered layout and linkage of each component, the punching action is kept stable, reducing structural shaking during the punching process, allowing the force of manual operation to be smoothly transmitted to the punching end, reducing physical consumption during operation, simplifying the overall operation process, and improving the continuity of punching operation.

[0031] Please see Figures 1-4 and Figure 6 The frame support assembly 1 includes a frame body 11, a top frame 41 fixedly installed on the top of the frame body 11, and a quick mold adjustment assembly 2 fixedly installed on the top of the frame body 11. An electrical enclosure 12 is provided on the rear side of the frame body 11. By setting the frame body 11 to provide a fixed carrier for the top frame 41 and the quick mold adjustment assembly 2, the frame body 11 can maintain the stability of the overall structure during use. The electrical enclosure 12 is located on the rear side of the frame body 11, which can centrally store electrical components, making the overall layout of the equipment more regular. Through the unified support of the top frame 41 and the quick mold adjustment assembly 2 by the frame body 11, the relative positions of each component are kept stable during punching operations, avoiding structural displacement. The layout of the electrical enclosure 12 can reduce the interference of external debris on electrical components, keep the equipment operating status consistent, reduce the complexity of daily maintenance, and improve the convenience of overall operation.

[0032] Please see Figures 1-4 and Figure 6The frame body 11 has trays 13 fixedly installed in a linear arrangement at equal intervals inside. The electrical enclosure 12 has an inspection door 14 on the outside. By setting the trays 13 in a linear arrangement inside the frame body 11, tooling and molds can be stored in categories, which can reduce the chaos caused by random placement of tools during use. By setting the inspection door 14 on the outside of the electrical enclosure 12, the internal electrical components can be directly opened for inspection and maintenance, which simplifies the equipment maintenance process. The equal-interval arrangement of the trays 13 can improve space utilization. The setting of the inspection door 14 can shorten the time for troubleshooting and handling, making the use and maintenance of the equipment on the production site more convenient.

[0033] Please see Figures 1-4 and Figure 6 Caster frames 15 are installed at the four corners of the bottom of the frame body 11. Casters 16 are rotatably connected to the inner side of the caster frames 15. By setting caster frames 15 and casters 16 at the four corners of the bottom of the frame body 11, the overall position of the equipment can be flexibly moved according to the needs of the production site during use. The caster frames 15 can drive the casters 16 to complete the turning action, thereby adapting to different production layouts and work areas. Through the cooperation of caster frames 15 and casters 16, the manpower consumption when moving the equipment is reduced, making the transfer and placement of the equipment on the production site more flexible and improving the convenience of on-site use and layout.

[0034] Please see Figures 2-8The crank punching module 44 includes a mounting top seat 441, which is fixedly mounted on the upper front side of the mounting top frame 43. A hinged rocker arm 442 is rotatably connected to the top of the mounting top seat 441. A sliding rod 443 is hinged to the bottom of the hinged rocker arm 442, and slides inside the mounting top seat 441. A lifting plate 444 is fixedly mounted on the bottom of the sliding rod 443, passing through the top plate 42 and the top frame 41. A punching die 445 is mounted on the bottom of the lifting plate 444 by screws. A crank handle 446 is rotatably connected to the upper side of one side of the mounting top seat 441. The inner side of the crank handle 446 is connected to one side of the hinged rocker arm 442 via a coupling. A manual handle 447 is fixedly mounted on the outer end of the crank handle 446. The mounting top seat 441 is configured to lift the hinged rocker arm 442 and the crank handle 446. The system provides support for installation, allowing the hand handle 447 to rotate the crank handle 446 during use. The crank handle 446, via a coupling, drives the hinge-connected rocker arm 442 to rotate within the mounting top seat 441. As the hinge-connected rocker arm 442 rotates, it pushes the sliding rod 443 downward within the mounting top seat 441. The sliding rod 443 drives the lifting plate 444 to move downward simultaneously. The lifting plate 444 then drives the bottom punching die 445 downward to complete the punching action. Through the transmission cooperation between the hinge-connected rocker arm 442, the sliding rod 443, and the lifting plate 444, the force of manual rotation is converted into a vertically downward punching force, reducing the force required for manual operation. The punching die 445 is directly installed at the bottom of the lifting plate 444 with screws, allowing for quick disassembly and replacement. This simplifies the punching operation process and reduces the time spent on punching preparation.

[0035] Please see Figures 6-8 Both ends of the lifting plate 444 are fixedly connected to sliding support sleeves 448. The inner side of the sliding support sleeves 448 is slidably connected to a support guide shaft 449. The top of the support guide shaft 449 is connected to the bottom of the top plate 42, and the bottom of the support guide shaft 449 is connected to the top of the frame. By setting sliding support sleeves 448 and support guide shafts 449 at both ends of the lifting plate 444 to cooperate with each other, the sliding support sleeves 448 can slide along the support guide shaft 449 in a directional manner during use. The support guide shaft 449 forms a fixed support with the frame through the top plate 42, thereby constraining the movement direction of the lifting plate 444 and preventing the lifting plate 444 from shifting laterally during the punching process. The cooperation between the sliding support sleeves 448 and the support guide shaft 449 can disperse the force generated during punching, maintain the movement state of the lifting plate 444 and the punching die 445, reduce the deviation of the punching action, and ensure that the manually applied force can be stably transmitted, reducing the operational difficulty in the punching process.

[0036] Please see Figures 6-8A control box 45 is fixedly installed on the upper side of one side of the top frame 41. A PLC controller 46 is located inside the control box 45. The front of the PLC controller 46 has a display screen and control buttons. By setting the control box 45 on the upper side of one side of the top frame 41, the PLC controller inside the control box 45 can receive and process operation signals during use. The display screen and control buttons can be used to complete parameter input and command sending. Action commands are transmitted to the PLC controller through the control buttons. The PLC controller controls the corresponding components to perform actions according to the input parameters. The display screen can provide real-time feedback on the equipment's operating status and parameter information, allowing manual operation to intuitively view and adjust the equipment's operating parameters, simplifying the parameter setting process, reducing operational errors, and improving the convenience of equipment control.

[0037] Please see Figures 1-6 The rapid die adjustment assembly 2 includes a mounting base 21, which is screwed to the top center of the frame body 11. A guide rail 22 is fixedly mounted on the top of the mounting base 21. A lead screw 23 is rotatably connected to the inner side of the guide rail 22, and a slide 24 is threadedly connected to the outer surface of the lead screw 23. The slide 24 moves on the top of the guide rail 22, and the outer end of the lead screw 23 passes through the guide rail 22. By setting the mounting base 21, a fixed foundation is provided for the guide rail 22 and the lead screw 23, so that when in use, rotating the lead screw 23 can drive the slide 24 to move directionally along the guide rail 22. When the slide 24 moves, it can drive the upper part to move synchronously, thereby adjusting the corresponding punching position. Through the threaded transmission cooperation between the lead screw 23 and the slide 24, the position adjustment process is kept uniform and controllable. The screw-fixed mounting base 21 can maintain the connection strength of the overall structure. The guide rail 22 provides sliding constraints for the slide 24 to prevent the slide 24 from swaying when moving, making the position adjustment process easier to control and reducing the adjustment time and operation steps.

[0038] Please see Figures 1-6 An adjusting handle 25 is fixedly installed at the outer end of the lead screw 23 through the guide rail 22. A bellows cover is provided on the outer side of the guide rail 22 for dust protection. By setting the adjusting handle 25 at the outer end of the lead screw 23, rotating the adjusting handle 25 can directly drive the lead screw 23 to rotate, thereby driving the slide 24 to complete the position adjustment. The bellows cover on the outer side of the guide rail 22 can cover the outside of the guide rail 22 and the lead screw 23, preventing debris and dust from the production site from entering the interior of the guide rail 22, and avoiding foreign objects from affecting the normal transmission of the lead screw 23 and the slide 24. The setting of the adjusting handle 25 makes the position adjustment operation easier to apply force. The setting of the bellows cover can reduce the wear and jamming of internal components, extend the service life of the transmission structure, and reduce the frequency of daily cleaning and maintenance of the equipment.

[0039] Please see Figures 1-6The manually triggered rotary positioning assembly 3 includes a gearbox 31, which is fixedly mounted on the top of the slide 24. A drive motor 32 is fixedly mounted on the outside of the gearbox 31. A transmission gear set is provided inside the gearbox 31. The output end of the drive motor 32 is connected to the input end of the transmission gear set. A support plate 33 is rotatably connected to the top of the gearbox 31. A clamping positioning steel plate 34 is detachably mounted on the top of the support plate 33 by screws. By setting the gearbox 31 to provide a closed installation space for the transmission gear set, the drive motor 32 can drive the transmission gear set to rotate during use. The rotation of the wheel set can drive the top support plate 33 to rotate synchronously. The clamp positioning steel plate 34, which is installed on the top of the support plate 33 by screws, can rotate together with the support plate 33, thereby completing the material station switching. The gearbox 31 moves synchronously with the slide 24 and can cooperate with the quick mold adjustment assembly 2 to complete the overall position adjustment. The clamp positioning steel plate 34 adopts a screw-removable installation method, which can be quickly disassembled and replaced. The drive motor 32 cooperates with the transmission gear set to drive the support plate 33 to rotate at a set angle, so that the station switching process remains stable, reduces the operation steps of manually adjusting the station, and improves the efficiency of station switching.

[0040] The working principle of this invention is as follows: Select a matching punching die 445 and a fixture positioning steel plate 34 according to the specifications of the wet friction pad to be processed. Install the punching die 445 to the bottom of the lifting plate 444 with screws, and install the fixture positioning steel plate 34 to the top of the bearing plate 33 with screws. Rotate the adjusting handle 25 to drive the lead screw 23 to rotate. The lead screw 23 drives the slide 24 to move along the guide rail 22. The slide 24 drives the upper gearbox 31 and the bearing plate 33 to move as a whole. Adjust the center position of the punching die 445 and the bearing plate 33 so that the center of the punching die 445 coincides with the center of the bearing plate 33. The bellows cover on the outside of the guide rail 22 covers the surface of the guide rail 22 and the lead screw 23, preventing paper debris from entering the gap between the guide rail 22 and the lead screw 23, reducing wear and jamming of moving parts. Turn on the power to the equipment, and set the number of equal divisions of the bearing plate 33 on the display screen using the control buttons. Control the PLC inside the chassis 45. The controller receives and stores the parameter, pulls the manual handle 447 to rotate the crank handle 446, the crank handle 446 drives the hinge-connected rocker arm 442 to rotate through the coupling, the hinge-connected rocker arm 442 pushes the sliding rod 443 to slide downward along the inside of the mounting top seat 441, the sliding rod 443 drives the lifting plate 444 to move down, so that the bottom of the punching die 445 is in contact with the surface of the fixture positioning steel plate 34, locking the corresponding limit structure, and completing the calibration of the punching depth. The sliding support sleeves 448 at both ends of the lifting plate 444 slide along the support guide shaft 449, the support guide shaft 449 restricts the movement direction of the lifting plate 444, and prevents the lifting plate 444 from deviating in the horizontal direction.

[0041] The base paper is placed on the surface of the fixture positioning steel plate 34, aligned with the positioning reference, and the friction plate substrate is attached. After confirming the positioning, the manual handle 447 is pulled to complete one punching action. The transmission structure of the hinge connecting the rocker arm 442 and the sliding rod 443 converts the manual rotation force into vertical punching force, realizing the punching and separation of the base paper. After punching, a rotation command is sent through the control button. The PLC controller controls the drive motor 32 to start. The drive motor 32 drives the bearing plate 33 to rotate at a preset angle through the transmission gear set in the gearbox 31, realizing the switching of the work position. After the rotation is completed, the punching action is repeated. The above punching and rotation steps are repeated. According to the production requirements, the fixture positioning steel plate 34 is flipped and aligned to continue to complete multi-station punching until the circular punching and assembly of the base paper is completed.

[0042] After the base paper is punched and assembled, the friction pad substrate with the base paper attached is removed from the surface of the clamping positioning steel plate 34 and transferred to the subsequent bonding process. Paper base debris is cleaned from the punching die 445, the bearing plate 33, and the equipment surface to avoid debris residue affecting the positioning accuracy of subsequent processing. When processing wet friction pads of different specifications, the equipment status is switched by controlling the buttons. The PLC controller automatically saves the current steel plate input and detection count information, eliminating the need for manual counting. The punching die 445 at the bottom of the lifting plate 444 and the clamping positioning steel plate 34 at the top of the bearing plate 33 are disassembled and replaced with punching dies 445 and clamping positioning steel plates 34 of the corresponding specifications. The die center calibration and parameter setting steps are repeated. After the changeover is completed, production can continue. After the production operation is completed, the equipment power is turned off, and paper base debris and dust are cleaned from the entire working surface of the equipment. Tools and spare dies are placed in the placement tray 13 inside the frame body 11 to achieve centralized tooling. The machine frame 11 has caster brackets 15 at the bottom that can drive casters 16 to enable the equipment to move freely and adjust its position on the production site, adapting to different production line layout requirements. The electrical housing 12 at the rear of the machine frame 11 houses all the basic electrical components of the equipment. The maintenance door 14 on the outside of the electrical housing 12 can be opened for daily inspection and fault repair of the internal electrical components. The top frame 41 provides support for the manual crank punching assembly 4. The top plate 42 is fixedly installed with the top frame 43 and the support guide shaft 449. The mounting bracket 441 of the crank punching module 44 is fixed by the top frame 43.

[0043] This technical solution addresses the systemic compatibility issues of existing equipment in small-batch production of wet friction plates through a fully manual core operation combined with basic electrical auxiliary structural design. The manually triggered rotary positioning component 3, via a drive motor 32 and transmission gear set, drives the bearing plate 33 to achieve equal rotation at a preset angle. Combined with the screw 23 and slide 24 structure of the rapid die adjustment component 2, it enables stepless rapid adjustment of the die center position, ensuring the concentricity of the punching die 445 and the bearing plate 33, improving the positional accuracy of paper base punching, and preventing adhesion deviations between the paper base and the friction plate substrate, eliminating the need for subsequent manual correction. The manual crank punching component 4, through a hinged transmission structure connecting the rocker arm 442 and sliding rod 443, converts manual rotational force into a stable vertical punching force, ensuring uniform punching force and reducing paper base damage. The screw 23 and slide 24 of the rapid die adjustment component 2, along with the single-set screw detachable installation method of the punching die 445 and the clamping positioning steel plate 34, shortens the total time for die replacement and calibration. The PLC... The controller automatically saves production count information, further improving the equipment's changeover efficiency. The placement tray 13 inside the frame body 11 provides dedicated tooling storage space, preventing tools and molds from being randomly placed and reducing tooling loss and misuse. The accordion cover on the outside of the guide rail 22 continuously prevents paper debris from entering the gaps between moving parts, reducing the frequency of daily maintenance and extending the service life of moving parts. The equipment as a whole lacks complex automatic feeding, robotic arms, and loading / unloading mechanisms, significantly reducing equipment procurement and subsequent maintenance costs. It is suitable for the cost control requirements of small-batch production. The manual operation mode allows workers to control the punching process in real time and adjust operating actions promptly, avoiding the problems associated with automated equipment. To prevent batch product scrapping due to misoperation, the cooperation between the support guide shaft 449 and the sliding support sleeve 448 restricts the movement trajectory of the lifting plate 444, ensuring the consistency of the punching action and further improving the uniformity of punching dimensions. The setting of the caster frame 15 and the universal wheels 16 allows the equipment to be flexibly adjusted according to production needs without the need for a fixed installation foundation, adapting to different production site layouts. The crank transmission structure reduces the force required for manual operation, and the height of the equipment operating surface meets the needs of conventional production operations, reducing the labor intensity of workers operating for a long time. The setting of the electrical enclosure 12 and the maintenance door 14 facilitates the daily maintenance and fault diagnosis of the equipment's electrical system, increasing the equipment's operating time.
