Description

Technical Field

[0001] This application relates to the field of molds, and in particular to a stamping mold structure for a right armrest bracket of a left rear seat. Background Technology

[0002] In today's booming automotive industry, the importance of automotive interior component manufacturing is increasingly prominent. Automotive interior components not only affect the aesthetics and comfort of a car but also directly impact the driving and riding experience for consumers. Among these, automotive seat components, as a key part of the interior, receive significant attention regarding their manufacturing processes and quality standards. The quality of seat components determines not only the overall performance and lifespan of the seat but also is closely linked to passenger safety and comfort. Stamping dies, as the core tool in the production process of automotive seat components, directly determine the quality of the product and the speed of production. Efficient and precise stamping dies ensure the dimensional accuracy and surface quality of seat components, meeting the stringent requirements of automotive manufacturing and thus enhancing the overall market competitiveness of automotive products.

[0003] A related technology includes a stamping die, comprising a lower die base extending along a first direction, with a forming punch at the top for placing a product; an upper die base disposed parallel to the lower die base along the first direction, with a forming die at the bottom adapted to the forming punch; an adjustment mechanism including a first positioning component, a second positioning component, a third positioning component, and a fourth positioning component; the first positioning component and the second positioning component are disposed on both sides of the forming punch along the first direction for adjusting the position of the forming punch in the first direction; the third positioning component and the fourth positioning component are disposed on both sides of the forming punch along a second direction for adjusting the position of the forming punch in the second direction, and when the upper die base moves relative to the lower die base along a third direction, the forming punch and the forming die correspond along the first direction to press and fit together to stamp the product, wherein the first direction, the second direction, and the third direction are perpendicular to each other.

[0004] Existing stamping dies suffer from a significant and pressing problem in practical applications: poor noise control. During the stamping process, the upper and lower punches collide directly. Specifically, in conventional dies, all punches act on the material strip simultaneously during stamping, resulting in a massive impact force from this simultaneous, one-time deformation collision. The instantaneous release of this impact force leads to extremely high noise levels and very loud sounds. Prolonged exposure to this high-noise working environment not only severely damages the acoustics of the workplace, affecting operators' mood and communication efficiency, but may also cause irreversible hearing damage, leading to hearing loss, tinnitus, and other health problems, posing a significant threat to the physical and mental health of operators. Summary of the Invention

[0005] In order to effectively reduce the noise generated during the stamping process of the stamping die, improve the acoustic environment of the workplace, avoid physical and mental health problems such as hearing loss, emotional impact and reduced communication efficiency caused by long-term exposure to high noise environment, and improve the work experience and safety of operators, this application provides a stamping die structure for the right armrest bracket of the left rear seat.

[0006] The technical solution for the stamping die structure of the right armrest bracket of the left rear seat provided in this application is as follows:

[0007] A stamping die structure for a right-side armrest support of a left rear seat includes an upper die and a lower die. Between the upper and lower dies are sequentially arranged a first punching mechanism, a second punching mechanism, an initial bending mechanism, a bending and punching mechanism, a two-sided bending mechanism, a drilling mechanism, and a cutting mechanism. The first punching mechanism is used to punch a central isolation hole and a first end isolation hole on the strip material. The second punching mechanism is used to cut a first interval isolation hole on the strip material. The initial bending mechanism is used to perform a preliminary bending of the workpiece. The bending and punching mechanism is used to punch holes while bending the workpiece. The two-sided bending mechanism is used to bend both sides of the workpiece. The drilling mechanism is used to drill holes in the top and side walls of the workpiece. The cutting mechanism is used to cut the stamped workpiece from the strip material.

[0008] By adopting the above technical solution, the first punching mechanism first punches out the middle isolation hole and the first end isolation hole on the strip. The second punching mechanism then cuts out the first interval isolation hole. The initial bending mechanism initially bends the workpiece. The bending and punching mechanism punches holes while bending. The two-sided bending mechanism bends the workpiece on both sides. The drilling mechanism drills holes on the top and side walls of the workpiece. Finally, the cutting mechanism cuts the workpiece off the strip. This series of mechanisms processes the strip step by step and in an orderly manner, avoiding the simultaneous deformation and hard collision of the punch, effectively reducing the impact force during the stamping process, thereby significantly reducing the noise level, improving the acoustic environment of the workplace, and preventing operators from suffering hearing damage, emotional distress, and reduced communication efficiency due to long-term exposure to high noise environments. This enhances the operator's work experience and safety.

[0009] Optionally, the first punching mechanism includes an intermediate punch block and a first end punch block, both of which are fixed to the lower surface of the upper die. The intermediate punch block and the first end punch block protrude from the upper die at different heights, and the bottom ends of the intermediate punch block and the first end punch block are provided with grooves of different shapes.

[0010] By adopting the above technical solution, the first punching mechanism is equipped with a middle punch and a first end punch, both of which are fixed to the lower surface of the upper die. By utilizing the different heights of the middle punch and the first end punch protruding from the upper die, they can contact the strip at different times during stamping, avoiding violent hard collisions caused by simultaneous action, and reducing impact force and noise. At the same time, different shaped grooves are opened at the bottom of the two, which can accurately punch out the middle isolation hole and the first end isolation hole on the strip according to actual needs, meeting the requirements of different hole shapes and processing sequences in the stamping of the right armrest bracket of the left rear seat, improving the accuracy of punching and the quality and efficiency of die stamping operations.

[0011] Optionally, the second punching mechanism includes a first connecting punch block, which is fixed to the lower surface of the upper die and protrudes from the lower surface of the upper die, for cutting a first interval isolation hole on the strip; the first connecting punch block slides in conjunction with a corresponding first connecting punch hole on the lower die, and the shape of the first connecting punch hole is adapted to the shape of the first connecting punch block to ensure the smooth progress of the punching process; the lower die is also provided with a connecting discharge hole communicating with the first connecting punch hole, for discharging the punched waste material.

[0012] By adopting the above technical solution, the first connecting punch block in the second punching mechanism is fixed to the lower surface of the upper die and protrudes, so that it can accurately act on the strip to cut out the first interval isolation hole during punching. The first connecting punch block and the first connecting punch hole of the appropriate shape on the lower die slide and cooperate, which not only ensures the stable movement of the punch block during the punching process and makes the punching action accurate, but also effectively disperses the impact force during punching and reduces the wear of the die. At the same time, the lower die has a connecting blanking hole connected to the first connecting punch hole, which can smoothly discharge the punched waste in time, avoid the accumulation of waste affecting the punching quality and normal operation of the die, improve the efficiency and stability of the entire stamping process, and ensure the stamping quality of the right armrest bracket of the left rear seat.

[0013] Optionally, the initial bending mechanism includes a first upper bending seat and a first lower bending seat. The first upper bending seat is fixed on a first upper mounting seat, and the first lower bending seat is fixed on a lower mounting seat. The first lower bending seat is located directly below the first upper bending seat. The lower surface of the first upper bending seat is curved. A first upper bending protrusion is fixedly provided on the first upper bending seat. A first upper bending groove is provided on the first upper bending seat. The upper surface of the first lower bending seat is a curved surface structure adapted to the first upper bending seat. A first lower bending groove adapted to the first upper bending protrusion is provided on the first lower bending seat. The first lower bending protrusion is adapted to the first upper bending groove.

[0014] By adopting the above technical solution, in the initial bending mechanism, the first upper bending seat is fixed to the first upper mounting seat, and the first lower bending seat is fixed to the lower mounting seat, with the two facing each other. During stamping, they can precisely cooperate to perform bending operations on the workpiece. The lower surface of the first upper bending seat is curved and has a first upper bending protrusion and a first upper bending groove. The upper surface of the first lower bending seat is an adaptable curved surface and has a corresponding first lower bending groove and a first lower bending protrusion. This mutually adaptable curved surface and protrusion / groove structure allows the workpiece to gradually and uniformly deform according to the preset shape during the bending process. This not only achieves a relatively accurate initial bending of the workpiece to meet the processing shape requirements of the right armrest bracket of the left rear seat, but also disperses the bending force, reduces local stress concentration, reduces the risk of damage to the workpiece and mold during bending, and improves the service life of the mold and the bending quality of the workpiece.

[0015] Optionally, the bending and punching mechanism includes a second upper bending seat, a second lower bending seat, a second end punch, and an end upper punch. The second upper bending seat is fixed to a second upper mounting seat, and the second lower bending seat is fixed to a lower template. The lower surface of the second upper bending seat and the upper surface of the second lower bending seat are both curved surfaces to achieve further bending of the workpiece. The second end punch is fixed to the second upper bending seat and slides into a second end punch on the second lower bending seat to further cut the first interval isolation hole into a second interval isolation hole. The end upper punch is fixed to the second upper mounting seat and cooperates with the end punch on the second lower bending seat to process the second end isolation hole on the strip.

[0016] By adopting the above technical solution, the bending and punching mechanism achieves multi-functional collaborative operation in the stamping process. The second upper bending seat and the second lower bending seat are respectively fixed to the second upper mounting seat and the lower template. Their opposing curved surface structures can apply uniform and compliant pressure to the workpiece when the mold is closed, achieving further precise bending of the workpiece and ensuring that the workpiece shape meets the processing standards of the right armrest bracket of the left rear seat. At the same time, the second end punch is fixed to the second upper bending seat and slides in cooperation with the second end punch on the second lower bending seat. During the bending process, it can simultaneously cut the first interval isolation hole and further process it into the second interval isolation hole, improving processing efficiency. The end upper punch cooperates with the end punch on the second lower bending seat to accurately process the second end isolation hole on the strip, meeting the diverse hole position requirements of the product. This integration of bending and punching processes reduces the number of molds used and the number of stamping times, lowers production costs, and improves the overall processing accuracy and stability.

[0017] Optionally, the two-sided bending mechanism includes a third upper bending seat and a third lower bending seat. The third upper bending seat includes a first positioning block and two upper bending blocks. The first positioning block and the two upper bending blocks are all fixed on the upper template. The first positioning block is located between the two upper bending blocks. The two sides of the first positioning block abut against the inner sidewalls of the two upper bending blocks respectively. A positioning protrusion is fixedly provided on the upper part of the first positioning block. A bending groove is formed between the first positioning block and the two upper bending blocks. The third lower bending seat includes a first fixing block and a bending protrusion fixedly connected. The first fixing block is fixed on the lower template. A first positioning groove adapted to the positioning protrusion is provided on the upper part of the bending protrusion to realize the bending of the two sides of the workpiece.

[0018] By adopting the above technical solution, during stamping, the first positioning block of the third upper bending seat, with its positioning protrusion precisely engaging with the first positioning groove on the bending protrusion of the third lower bending seat, can quickly and accurately position the workpiece, ensuring precise bending. The bending grooves formed by the two upper bending blocks and the first positioning block provide suitable space and guidance for bending on both sides of the workpiece. During mold closing, the first positioning block and the upper bending blocks apply downward pressure together, cooperating with the third lower bending seat, causing the two sides of the workpiece to deform uniformly according to the preset shape, achieving precise bending. This not only improves the accuracy and quality of bending on both sides of the workpiece but also reduces the scrap rate.

[0019] Optionally, the drilling mechanism includes a positioning component and a top drilling component. The positioning component includes a second positioning block fixed on a second upper mounting base. The second positioning block is provided with a second positioning groove and a plurality of positioning protrusions for positioning the workpiece when it is conveyed to the position of the positioning component. The top drilling component includes a first mounting block and a second mounting block fixed on a second upper mounting base, and a plurality of vertical punches mounted thereon for simultaneously drilling a plurality of first through holes on the top of the workpiece.

[0020] By adopting the above technical solution, during the stamping process, when the workpiece is conveyed to the drilling mechanism, the positioning component plays its role. The second positioning block, fixed on the second upper mounting base, can quickly and accurately position the workpiece with its second positioning groove and multiple positioning protrusions, ensuring that the workpiece is in the correct position and providing a precise reference for subsequent drilling processes. Subsequently, the top drilling component begins to work. The first and second mounting blocks, fixed on the second upper mounting base, provide stable support for multiple vertical punches. Multiple vertical punches can simultaneously drill multiple first through holes on the top of the workpiece, realizing multi-hole processing with one positioning. This not only improves drilling efficiency and accuracy and ensures the relative positional accuracy between holes, but also reduces the accumulation of errors caused by multiple positioning, improving the overall processing quality of the right armrest bracket of the left rear seat.

[0021] Optionally, the drilling mechanism further includes a sidewall drilling assembly, which includes a transverse drilling component and a lifting guide component. The transverse drilling component includes a transverse block and a horizontal punch. The transverse block slides with a second upper mounting base, and one end of the horizontal punch is fixedly connected to the sidewall of the transverse block. The lifting guide component includes a second fixing block fixed on the upper template, two third mounting blocks, and two driving components. The driving component includes a connecting block and a driving block. The driving block is located in a driving groove opened at both ends of the transverse block, and the driving block slides with the driving groove, thereby machining a second through hole in the sidewall of the workpiece.

[0022] By adopting the above technical solution, when the drilling mechanism is working, the side wall drilling component begins to function after the positioning component completes the precise positioning of the workpiece. The second fixed block and the third mounting block in the lifting guide provide stable support for the driving component. The driving block in the driving component slides in the driving grooves at both ends of the transverse block, which can drive the transverse block to move laterally along the sliding engagement direction with the second upper mounting seat. At the same time, the horizontal punch fixed to the side wall of the transverse block moves synchronously with the transverse block. During the transverse movement, the horizontal punch can accurately act on the side wall of the workpiece, thereby machining the second through hole in the side wall of the workpiece. This allows the side wall drilling operation to be coordinated with the top drilling process in an orderly manner, realizing multi-directional drilling of different parts of the workpiece in one positioning, improving drilling efficiency and processing accuracy, reducing errors caused by multiple clamping and positioning, ensuring the accuracy and consistency of the hole positions on the right armrest bracket of the left rear seat, and improving the overall quality of the product.

[0023] Optionally, the cutting mechanism includes a clamping assembly and a cutter. The clamping assembly includes a lower clamping block fixed to the lower die and an upper clamping block fixed to the upper die (2). A positioning post is fixedly provided on the upper clamping block, and a sliding hole is provided on the lower clamping block. The upper clamping block and the lower clamping block cooperate to clamp the workpiece. The positioning post passes through a first through hole on the workpiece and a sliding hole on the lower clamping block. The positioning post is used to position the workpiece. The cutter is fixed to a second upper mounting base. An edge material discharge hole is provided on the lower die plate for sliding cooperation. The cutter slides with the edge material discharge hole to cut the stamped workpiece off the strip.

[0024] By adopting the above technical solution, during the cutting operation, the lower clamping block is fixed to the lower template, and the upper clamping block is fixed to the second upper mounting base. Together, they form a stable clamping mechanism for the workpiece. The positioning pin and positioning hole clamp the workpiece, ensuring that it does not shift during cutting and guaranteeing cutting accuracy. The positioning pin passes through the first through hole on the workpiece and the sliding hole of the lower clamping block, further enhancing the precise positioning of the workpiece and preventing it from moving horizontally. It also guides the workpiece to move within a reasonable range, ensuring the accuracy of the cutting position. During the cutting operation, the cutter fixed to the second upper mounting base moves downward with the upper mounting base, sliding and engaging with the scrap discharge hole on the lower template. This cleanly and precisely cuts the stamped workpiece from the strip, while the scrap material is smoothly discharged through the scrap discharge hole, preventing scrap accumulation from affecting subsequent processing and improving production efficiency and product quality.

[0025] Optionally, the stamping die structure further includes a scrap conveying system, which includes a first belt assembly, a second belt assembly, and a third belt assembly. The first belt assembly is disposed on the bottom plate of the lower die, located directly below the scrap discharge holes generated by the first and second punching mechanisms, and is used to convey scrap along the width direction of the die. The second belt assembly is disposed on a support base, located directly below the scrap discharge holes generated by the bending and punching mechanism, and is used to convey scrap along the width direction of the die. The third belt assembly is disposed on the bottom plate, located directly below the edge scrap discharge holes generated by the cutting mechanism, and is used to convey edge scrap along the width direction of the die.

[0026] By adopting the above technical solution, during the operation of the stamping die, the first punching mechanism, the second punching mechanism, the bending and punching mechanism, and the cutting mechanism generate waste and edge material when completing their respective processing steps. At this time, the waste conveying system plays a crucial role. The first belt assembly is located on the lower die base plate and directly below the waste discharge holes of the first and second punching mechanisms, enabling it to promptly collect and convey the waste generated from these two locations along the width of the die. The second belt assembly is placed on the support base, precisely corresponding to the waste discharge hole of the bending and punching mechanism, effectively conveying the waste generated by this mechanism. The third belt assembly is located on the base plate corresponding to the edge material discharge hole of the cutting mechanism, responsible for conveying the edge material waste generated by cutting along the width of the die. This zoned and targeted waste conveying system achieves the orderly collection and conveying of waste generated from different processes, avoiding waste accumulation within the die, preventing waste from interfering with the normal operation and processing accuracy of the die, ensuring the continuous, stable, and efficient operation of the stamping die, and improving production efficiency and product quality.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By setting up multiple mechanisms that perform different processing steps in sequence, such as the first punching mechanism, the second punching mechanism, and the initial bending mechanism, the punch acts on the material strip at different times, avoiding the one-time, simultaneous deformation and hard collision of the punch. This significantly reduces the impact force during the stamping process, thereby effectively reducing the noise level, improving the acoustic environment of the workplace, and preventing operators from experiencing hearing damage, emotional distress, and reduced communication efficiency due to long-term exposure to high noise environments. This enhances the operator's work experience and safety.

[0029] 2. In the first punching mechanism, the middle punch and the first end punch have different heights and different bottom groove shapes, which can accurately punch out holes of different shapes; the initial bending mechanism and the two side bending mechanisms, through mutually adapted curved surfaces and protrusion and groove structures, enable the workpiece to gradually and uniformly deform according to the preset shape, so as to achieve precise bending; in the drilling mechanism, the positioning component and the top and side wall drilling components cooperate to realize multi-directional drilling of different parts of the workpiece in one positioning, ensuring the relative position accuracy between each hole position;

[0030] 3. The bending and punching mechanism integrates the bending and punching processes into one, reducing the number of molds used and the number of punching operations, thus lowering production costs; the waste conveying system is divided into zones and is specifically equipped with first belt assemblies, second belt assemblies, and third belt assemblies to promptly receive and convey waste and edge materials generated from different processes, preventing waste accumulation from affecting the normal operation of the molds and processing accuracy.

[0044] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0045] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. Unless otherwise defined, the technical or scientific terms used in this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

[0046] For ease of understanding, in this embodiment, the length direction of the mold structure is defined as the first direction and the width direction of the mold structure is defined as the second direction. Based on this, the stamping mold structure of the right armrest bracket of the left rear seat will be explained.

[0047] This application discloses a stamping die structure for the right armrest bracket of the left rear seat. (Refer to...) Figure 1 The stamping die structure for the right armrest support of the left rear seat includes an upper die 2 and a lower die 3. Between the upper die 2 and the lower die 3, along the length of the die structure, are arranged a first punching mechanism 4, a second punching mechanism 5, an initial bending mechanism 6, a bending and punching mechanism 7, two side bending mechanisms 8, a drilling mechanism 9, and a cutting mechanism 10.

[0048] The upper die 2 includes a top plate 21 and an upper template 22, with the upper template 22 fixed to the lower surface of the top plate 21. The lower die 3 includes a base plate 31, a support base 32, and a lower template 33, with the support base 32 fixed to the upper surface of the base plate 31 and the lower template 33 fixed to the upper surface of the support base 32. In the vertical direction, the upper template 22 and the lower template 33 are aligned to ensure precise cooperation between the upper and lower dies 3 during the stamping process and improve stamping accuracy.

[0049] Reference Figure 1 , Figure 2 and Figure 3 The lower surface of the upper template 22 is sequentially fixed with a first upper mounting base 23 and a second upper mounting base 24 along the length of the mold structure. The end of the first upper mounting base 23 abuts against the end of the second upper mounting base 24, ensuring the stability of the mold structure and the continuity of the stamping process. The upper surface of the lower template 33 is sequentially fixed with a lower mounting base 34 along the length of the mold structure.

[0050] Reference Figure 2 and Figure 3Specifically, the first punching mechanism 4 includes an intermediate punch 41 and a first end punch 42, both fixed to a mounting base. Both protrude from the lower surface of the first upper mounting base 23, with different protrusion heights. The bottom ends of the intermediate punch 41 and the first end punch 42 are provided with grooves of different shapes. In terms of arrangement, the intermediate punch 41 and the first end punch 42 are spaced apart along the second direction, ensuring that during the punching process, they do not simultaneously collide with the material strip. Instead, they contact the material strip sequentially, avoiding the simultaneous, massive impact force generated by all punches. This effectively reduces noise generated during the punching process, improves the acoustic environment of the workplace, protects the operator's work mood and communication efficiency, and prevents irreversible damage to the operator's hearing caused by high noise, thus protecting the operator's physical and mental health.

[0051] Reference Figure 2 and Figure 3 From the perspective of shape adaptation, the shape of the first end punch 42 matches the shape of the first end isolation hole 12, while the shape of the middle punch 41 matches the shape of the middle isolation hole 11. The lower mounting base 34 has a through middle punch 341 and a first end punch 342, with the middle punch 341 precisely located below the middle punch 41, allowing the middle punch 41 to slide and engage with the middle punch 341. The first end punch 342 is also located directly below the first end punch 42, allowing for sliding engagement with the first end punch 342.

[0052] Reference Figure 3 , Figure 4 and Figure 5 When the first punching mechanism 4 starts working, under the driving action of the punch press, the first upper mounting seat 23 drives the middle punch block 41 and the first end punch block 42 to move downward together. During the pressing process, the middle punch block 41 passes through the material strip 1 and, with the cooperation of the middle punch hole 341 of the lower mounting seat 34, punches out the middle isolation hole 11 on the material strip 1; the first end punch block 42 passes through the material strip 1 and, with the cooperation of the first end punch hole 342 of the lower mounting seat 34, punches out the first end isolation hole 12 on the material strip 1.

[0053] Reference Figure 3 and Figure 4The upper surface of the lower die 33 has a through-hole 331 (central blanking hole) and a first end blanking hole 332. The central blanking hole 331 is directly below the central punch 341 and aligned with it. The first end blanking hole 332 is directly below the first end punch 342 and aligned with it. Furthermore, a first belt assembly 35 is provided on the base plate 31 of the lower die 3. Both the central blanking hole 331 and the first end blanking hole 332 are located directly above the first belt assembly 35, facilitating the transport of waste material. The punched waste material falls through the central blanking hole 331 and the first end blanking hole 332 respectively. Because the central blanking hole 331 is aligned with the central punch 341, the waste material can fall smoothly, avoiding blockage within the die. The falling waste material directly falls onto the first belt assembly 35 located directly below. The first belt assembly 35 transports the waste material generated by the first punching mechanism 4 along a second direction, thus completing the entire punching and waste material handling process.

[0054] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 The second punching mechanism 5 includes a connecting punch block 51, which is fixedly mounted on the lower surface of the first upper mounting base 23 and protrudes from the lower surface of the first upper mounting base 23. Its function is to cut the first interval isolation hole 13 on the material strip 1. The surface of the lower mounting base 34 is correspondingly provided with a through first connecting punch hole 343. The shape of the first connecting punch hole 343 is adapted to the shape of the connecting punch block 51, and the two can slide together to ensure the smooth progress of the punching process. The upper surface of the lower template 33 is also provided with a through connecting drop hole 333, which is precisely located directly below the first connecting punch hole 343 and is interconnected with the first connecting punch hole 343, providing a drop channel for the punched waste material.

[0055] Reference Figure 2 , Figure 3 and Figure 4 When the second punching mechanism 5 starts working, the first upper mounting base 23 drives the connecting punch block 51 to move downward under the action of the driving device. Since the connecting punch block 51 slides and engages with the first connecting punch hole 343 on the lower mounting base 34, and the shape of the first connecting punch hole 343 is adapted to the connecting punch block 51, the connecting punch block 51 will pass through the material strip 1 and cut a first interval isolation hole 13 on the material strip 1. The first interval isolation hole 13 is located between the first end isolation hole 12 and the middle isolation hole 11, and one end is connected to the first end isolation hole 12 and the other end is connected to the middle isolation hole 11.

[0056] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5The upper surface of the base plate 31 is provided with a first belt assembly 35, which is located directly below the connecting discharge hole 333, for conveying the waste generated by the second punching mechanism 5 along the second direction. Meanwhile, a first discharge track 36 is fixedly installed on the support base 32. The first discharge track 36 is inclined, with its top end located directly below the connecting discharge hole 333 and its bottom end located directly above the first belt assembly 35, facilitating the smooth sliding of waste. Waste generated during the punching process falls through the connecting discharge hole 333 on the lower template 33. Because the top of the first feeding track 36 is located directly below the connecting discharge hole 333, the waste material will first fall into the first feeding track 36. Since the first feeding track 36 is inclined, the waste material will slide down its inclined surface to the bottom. The bottom of the first feeding track 36 is located directly above the first belt assembly 35, so the waste material will eventually fall onto the first belt assembly 35. This ensures that the waste material generated by the second punching mechanism 5 can be transported away by the first belt assembly 35, avoiding the accumulation of waste material that affects the normal operation of the mechanism, and ensuring the efficient and stable operation of the entire punching process.

[0057] Reference Figure 2 The initial bending mechanism 6 includes a first upper bending seat 61 and a first lower bending seat 62. The first upper bending seat 61 is fixed to the lower surface of the first upper mounting seat 23, and the first lower bending seat 62 is fixed to the upper surface of the lower mounting seat 34, with the first lower bending seat 62 located directly below the first upper bending seat 61. This layout ensures the accuracy of the bending process. The lower surface of the first upper bending seat 61 is curved, and a first upper bending protrusion 611 is integrally formed on the lower surface of the first upper bending seat 61. A first upper bending groove 612 is also formed on the lower surface of the first upper bending seat 61. The first upper bending protrusion 611 and the first upper bending groove 612 are also curved structures, with one end of the first upper bending protrusion 611 located within the first upper bending groove 612.

[0058] Reference Figure 3 Correspondingly, the upper surface of the first lower bending seat 62 is also a curved structure. A first lower bending groove 621 is formed on the upper surface of the first lower bending seat 62, the shape of which matches the shape of the first upper bending protrusion 611. A first lower bending protrusion 622 is also integrally formed on the upper surface of the first lower bending seat 62, the shape of which matches the shape of the first upper bending groove 612. This allows the bending process to form complex curved shapes, meeting the bending requirements of the parts. This facilitates the stamping of the basic shape of the workpiece.

[0059] Reference Figure 2 and Figure 3When the initial bending mechanism 6 starts working, the first upper mounting seat 23 drives the first upper bending seat 61 to move downwards, gradually approaching the first lower bending seat 62. As the first upper bending seat 61 descends, the first upper bending protrusion 611 on its lower surface inserts into the first lower bending groove 621 on the upper surface of the first lower bending seat 62, while the first lower bending protrusion 622 on the upper surface of the first lower bending seat 62 enters into the first upper bending groove 612 on the lower surface of the first upper bending seat 61. During this process, since both the upper and lower surfaces are curved structures and the protrusion and groove are compatible, the workpiece placed between the first upper bending seat 61 and the first lower bending seat 62 is squeezed and shaped under pressure. The engagement of the first upper bending protrusion 611 and the first lower bending groove 621, as well as the engagement of the first lower bending protrusion 622 and the first upper bending groove 612, allows the workpiece to be bent according to a preset shape, forming a complex curved surface shape. This satisfies the bending requirements of the parts and facilitates the stamping of the workpiece's basic shape. The entire bending process relies on the precise engagement of the upper and lower seats and the unique curved surface structure to ensure the quality and accuracy of the bending.

[0060] Reference Figure 2 and Figure 3 The bending and punching mechanism 7 includes a second upper bending seat 71 and a second lower bending seat 72. The second upper bending seat 71 is fixed to the lower surface of the second upper mounting seat 24, and the second lower bending seat 72 is fixed to the upper surface of the lower template 33. The lower surface of the second upper bending seat 71 and the upper surface of the second lower bending seat 72 are both curved surfaces, which can enable further bending of the workpiece.

[0061] Reference Figure 2 , Figure 3 and Figure 4 Meanwhile, a second end punch 73 is fixedly provided on the lower surface of the second upper bending seat 71, and a through second end punch 77 is provided on the second lower bending seat 72. The second end punch 77 is located directly below the second end punch 73. The shape of the second end punch 77 is adapted to the shape of the second end punch 73. The second end punch 73 and the second end punch 77 slide and cooperate, thereby facilitating the further cutting of the first interval isolation hole 13 into the second interval isolation hole 14.

[0062] Continue to refer to Figure 2 , Figure 3 and Figure 4 The bending and punching mechanism 7 also includes an upper end punch 75 and a lower end punch 76. The upper end punch 75 is fixed to the lower surface of the second upper mounting base 24, and the lower end punch 76 is fixed to the upper surface of the lower template 33. The lower end punch 76 has a through end punch 77. The shape of the end punch 77 is adapted to the shape of the upper end punch 75, thereby realizing the processing of the second end isolation hole 15 on the strip.

[0063] Reference Figure 2 , Figure 3 and Figure 5 Meanwhile, the upper surface of the lower template 33 is provided with a through second end discharge hole 334 and an isolation discharge hole 335. The second end discharge hole 334 is located directly below the second end punch 77 and is interconnected with the end punch 77; the isolation discharge hole 335 is located directly below the end punch 77 and is interconnected with the end punch 77. A second belt assembly 37 is also provided on the support base 32. The second belt assembly 37 conveys waste material along a second direction. Both the second end discharge hole 334 and the isolation discharge hole 335 are located directly above the second belt assembly 37.

[0064] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 The bending and punching mechanism 7, through the precise cooperation of the second upper bending seat 71 and the second lower bending seat 72, achieves both complex bending and punching of the workpiece. The second upper bending seat 71 is fixed to the lower surface of the second upper mounting base 24, and its lower surface is curved to adapt to the shape requirements of the workpiece after bending. The second lower bending seat 72 is fixed to the upper surface of the lower template 33, corresponding to the second upper bending seat 71, and is also curved, ensuring a tight fit with the workpiece during mold closing and achieving a precise bending effect. This not only improves the bending accuracy but also ensures that the workpiece is subjected to uniform stress during the bending process, reducing the risk of cracking or deformation caused by stress concentration.

[0065] Continue to refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 Secondly, the bending and punching mechanism 7 integrates punching functionality while bending, further improving production efficiency. Specifically, a second end punch 73 is fixedly mounted on the lower surface of the second upper bending seat 71, which slides and engages with the second end punch 77 on the second lower bending seat 72. This allows the first interval isolation hole 13 to be further cut into the second interval isolation hole 14 while the workpiece is being bent. This avoids the secondary processing steps required in traditional processes, such as bending before punching or punching before bending, significantly shortening the production cycle and reducing production costs.

[0066] Continue to refer to Figure 2 , Figure 3 , Figure 4 and Figure 5Furthermore, the bending and punching mechanism 7 also achieves precise punching at another position on the workpiece through the setting of the upper end punch 75 and the lower end punch 76. The upper end punch 75 is fixed to the lower surface of the second upper mounting base 24 and cooperates with the end punch 77 opened on the lower end punch 76 to ensure accurate penetration of the workpiece during the punching process, thereby realizing the processing of the second end isolation hole 15 on the strip.

[0067] Continue to refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 The punches and holes in the bending and punching mechanism 7 employ irregular shapes and varying heights, ensuring that during the stamping process, the punches do not simultaneously collide with the strip material. Instead, they contact the strip sequentially, avoiding the massive, simultaneous impact force generated by all punches working at once. This significantly reduces noise generated during the stamping process, improves the acoustic environment of the workplace, protects the operator's work mood and communication efficiency, and also prevents irreversible hearing damage caused by high noise levels.

[0068] Reference Figure 2 and Figure 3 The bending mechanism 8 includes a third upper bending seat 81 and a third lower bending seat 82. The third upper bending seat 81 includes a first positioning block 811 and two upper bending blocks 812. The first positioning block 811 and the two upper bending blocks 812 are fixed to the lower surface of the upper template 22. The first positioning block 811 is located between the two upper bending blocks 812, and its two sides abut against the inner sidewalls of the two upper bending blocks 812, ensuring the stability and positioning accuracy of the workpiece during bending. The height of the first positioning block 811 protruding from the upper template 22 is less than the height of the two upper bending blocks 812. The lower surface of the first positioning block 811 is integrally formed with a positioning protrusion 813. A bending groove is formed between the first positioning block 811 and the two upper bending blocks 812, and the lower surfaces of the first positioning block 811 and the two upper bending blocks 812 are curved surfaces.

[0069] Reference Figure 3 The third lower bending seat 82 includes an integrally formed first fixing block 821 and a bending protrusion 822. The first fixing block 821 is fixed to the upper surface of the lower template 33 by bolts. The upper surface of the bending protrusion 822 is provided with a first positioning groove 823, and the shape of the bending protrusion 822 is adapted to the shape of the bending groove. The two bending mechanisms 8 on both sides can be bent on both sides of the workpiece. In this embodiment, there are multiple two bending mechanisms 8 on both sides, which are arranged sequentially along the length of the mold structure, thereby realizing multiple bending of the two sides of the workpiece, so that the two sides of the workpiece can form complex bending shapes to meet the diverse needs of accessories.

[0070] Reference Figure 2 and Figure 3 When the bending mechanisms 8 on both sides start working, the upper template 22 drives the third upper bending seat 81 to move downward under the action of the driving device. During the descent of the third upper bending seat 81, the first positioning block 811 first approaches the workpiece, and the positioning protrusion 813 on its lower surface will insert into the corresponding positioning hole of the workpiece or fit against the surface of the workpiece. At the same time, the two upper bending blocks 812 will also approach the workpiece from both sides. Due to the cooperation between the first positioning block 811 and the upper bending block 812 and the action of the positioning protrusion 813, the workpiece is accurately positioned between the third upper bending seat 81 and the third lower bending seat 82.

[0071] Continue to refer to Figure 2 and Figure 3 As the third upper bending seat 81 continues to move downwards, the lower curved surfaces of the first positioning block 811 and the two upper bending blocks 812 gradually come into contact with the bending protrusion 822 of the third lower bending seat 82. Since the shape of the bending protrusion 822 matches the bending groove, under pressure, the workpiece will bend and deform along the curved surface shape of the upper and third lower bending seats 82. Multiple side bending mechanisms 8 are arranged sequentially, and the workpiece undergoes a bending operation each time it passes through each mechanism. Through multiple such bending processes, complex bending shapes can be formed on both sides of the workpiece, thereby meeting the diverse needs of different accessories.

[0072] Reference Figure 2 and Figure 3 The drilling mechanism 9 includes a second positioning block 91, a top drilling assembly 92, and a side wall drilling assembly 93. The second positioning block 91 is fixed to the upper surface of the second upper mounting base 24. A second positioning groove 911 is provided on the upper surface of the second positioning block 91. At the same time, a plurality of positioning protrusions 912 are also fixedly provided on the upper surface of the second positioning block 91. When the workpiece is conveyed to the position of the positioning assembly, the second positioning groove 911 and the plurality of positioning protrusions 912 simultaneously abut against the lower surface of the workpiece, thereby positioning the workpiece and ensuring the stability and positioning accuracy of the workpiece during the drilling process.

[0073] The top drilling assembly 92 includes a first mounting block 921, a second mounting block 922, a vertical punch 923, and a clamping block 924. Both the first mounting block 921 and the second mounting block 922 are fixed to the lower surface of the second upper mounting base 24. There are four vertical punches 923 and four clamping blocks 924. The four vertical punches 923 are arranged at intervals along a second direction, and their diameters can be the same or different. This allows the drilling process to simultaneously process multiple holes with different diameters, improving production efficiency. Three of the vertical punches 923 are fixed to the lower surface of the first mounting block 921, and the other vertical punch 923 is fixed to the lower surface of the second mounting block 922. The tips of all four vertical punches 923 pass through the second upper mounting base 24.

[0074] Reference Figure 7 and Figure 8 In this embodiment, there are four clamping blocks 924, each of which is fixed to the lower surface of the second upper mounting base 24 by bolts. Specifically, each vertical punch 923 has an anti-detachment block 925 integrally formed at its end. Three clamping blocks 924 are fixedly disposed on the lower surface of the first mounting block 921, and one clamping block 924 is fixedly disposed on the lower surface of the second mounting block 922. The number of clamping blocks 924 corresponds one-to-one with the number of vertical punches 923. Each clamping block 924 has interconnected anti-detachment holes 926 and through holes 927. The anti-detachment holes 926 and through holes 927 are interconnected. The anti-detachment blocks 925 of the four vertical punches 923 are respectively located in the corresponding anti-detachment holes 926, and the vertical punches 923 pass through the through holes 927, thereby achieving stable installation and positioning of the vertical punches 923. During the lifting and lowering process of the upper mold 2, the top drilling mechanism 9 simultaneously drills multiple first through holes 16 on the top of the workpiece.

[0075] Reference Figure 4 , Figure 6 , Figure 7 and Figure 8 When the top drilling assembly 92 starts working, the upper die 2 moves up and down under the action of the drive device. During the descent of the upper die 2, the top drilling assembly 92, fixed to the lower surface of the second upper mounting base 24, also moves downwards. As the assembly gradually approaches the workpiece, the four vertical punches 923 simultaneously contact the top surface of the workpiece. Due to the precise positioning and stable installation of the vertical punches 923, they can accurately drill holes in the workpiece along the vertical direction under pressure. Because the four vertical punches 923 can work simultaneously, multiple first through holes 16 can be drilled simultaneously on the top of the workpiece. Moreover, since the diameters of the vertical punches 923 can be different, the diameter of the drilled holes can also be flexibly varied according to requirements.

[0076] Reference Figure 9 The sidewall drilling assembly 93 includes a transverse drilling component 931 and a lifting guide component 932. The transverse drilling component 931 includes a transverse block 9311 and a horizontal punch 9312. The transverse block 9311 slides in engagement with the second upper mounting base 24. The horizontal punch 9312 extends along a first direction, and one end of the horizontal punch 9312 is fixedly connected to the sidewall of the transverse block 9311. The lifting guide component 932 includes a second fixing block 9321, two third mounting blocks 9322, and two driving components 9323. The second fixing block 9321 is fixed to the lower surface of the upper mold plate 2, and both third mounting blocks 9322 are fixed to the lower surface of the upper mold plate 2. The two driving components 9323 are respectively fixed to the sidewalls of the two third mounting blocks 9322 that are opposite to each other.

[0077] Reference Figure 9 and Figure 10 Specifically, each driving component 9323 includes an integrally formed connecting block 93231 and a driving block 93232. The connecting block 93231 is fixed to the side wall of the third mounting block 9322. Inclined driving grooves 9313 are provided at both ends of the transverse block 9311. The top of the driving groove 9313 is open, and the bottom of the driving groove 9313 is closed. The driving block 93232 is located within the driving groove 9313, and the driving block 93232 slides into the driving groove 9313, thereby machining a second through hole 17 on the side wall of the workpiece.

[0078] Reference Figure 9 and Figure 10 When the sidewall drilling assembly 93 starts working, the upper mold plate 2 moves up and down under the action of the drive device. Since the second fixing block 9321 and the third mounting block 9322 are both fixed to the lower surface of the upper mold plate 2, they move together with the upper mold plate 2. During the descent of the upper mold plate 2, the drive component 9323 fixed to the sidewall of the third mounting block 9322 also descends. The drive block 93232 on the drive component 9323 enters the inclined drive groove 9313 at both ends of the transverse block 9311. As the drive component 9323 continues to descend, the drive block 93232 slides in the drive groove 9313. Since the drive groove 9313 is inclined, the sliding motion of the drive block 93232 will generate a horizontal component force on the transverse block 9311, thereby pushing the transverse block 9311 to move horizontally on the second upper mounting seat 24. When the transverse block 9311 moves, the horizontal punch 9312 fixed to its sidewall will also move accordingly. When the horizontal punch 9312 contacts the side wall of the workpiece, under continuous pressure, it will machine a second through hole 17 into the side wall. Through the lifting and lowering motion of the upper die 2, combined with the special cooperation structure between the drive component 9323 and the transverse block 9311, the horizontal movement of the horizontal punch 9312 and the drilling operation are achieved, thus completing the task of machining the second through hole 17 into the side wall of the workpiece. The entire process relies on the precise cooperation and motion conversion between the various components to ensure the accuracy and stability of the drilling.

[0079] Reference Figure 2 , Figure 3 and Figure 5The cutting mechanism 10 includes a clamping assembly 101 and a cutter 102. The clamping assembly 101 includes a lower clamping block 1011, an upper clamping block 1012, and a positioning post 1013. The lower clamping block 1011 is fixed to the upper surface of the lower template 33. A sliding hole 1014 extending vertically is provided on the upper surface of the lower clamping block 1011, and the axis of the sliding hole 1014 coincides with the axis of the positioning post 1013. The positioning post 1013 can slide and engage within the sliding hole 1014. The upper clamping block 1012 is fixed to the lower surface of the second upper mounting base 24. The cutter 102 is also fixed to the lower surface of the second upper mounting base 24 and is located on one side of the upper clamping block 1012. A scrap material discharge hole 336 is provided on the upper surface of the lower template 33 corresponding to the position of the cutter 102, and the cutter 102 slides and engages with the scrap material discharge hole 336. In addition, a second inclined feeding track 337 is fixedly provided at the end of the lower template 33, and the top of the second feeding track 337 is located below the cutting mechanism 10. A third belt assembly 38 is also provided on the upper surface of the base plate 31, and the third belt assembly 38 is located directly below the edge material drop hole 336, for conveying the edge material waste generated by the second punching mechanism 5 along the second direction.

[0080] Continue to refer to Figure 2 , Figure 3 and Figure 5 When the upper die 2 begins to descend, it causes the upper clamping block 1012, the positioning pin 1013, and the cutter 102 to move downwards together. The upper clamping block 1012 and the lower clamping block 1011 cooperate to clamp the workpiece placed between them, preventing the workpiece from moving arbitrarily during processing. At the same time, the positioning pin 1013 passes through one of the first through holes 16 on the workpiece and the sliding hole 1014 on the lower clamping block 1011 in sequence, thereby accurately determining the position of the workpiece. The positioning function of the positioning pin 1013, combined with the clamping function of the upper and lower clamping blocks 1011, achieves a firm positioning of the workpiece, providing a stable foundation for subsequent cutting operations.

[0081] Continue to refer to Figure 2 , Figure 3 and Figure 5 After the workpiece is successfully positioned and clamped, the cutter 102 continues to descend with the upper mold 2 until it cuts into the edge material discharge hole 336 on the upper surface of the lower mold 33. As the cutter 102 cuts in, the edge material scrap cut off from the workpiece falls through the edge material discharge hole 336, while the cut workpiece slides down through the inclined second discharge track 337, completing the discharge process.

[0082] It is worth noting that in this embodiment, the ends of the intermediate punch 41, the first end punch 42, the first connecting punch 51, the first upper bending seat 61, the first lower bending seat 62, the second upper bending seat 71, the second lower bending seat 72, the third upper bending seat 81, and the third lower bending seat 82 are all curved, with front-to-back height differences, etc., so that the punches can generate a front-to-back time difference during the stamping process. The beneficial effect is that it effectively avoids the excessive noise generated by all punches impacting the strip 1 at the same time, reduces noise pollution during die stamping operations, improves the working environment, and also reduces the damage to the die and strip 1 that may be caused by excessive instantaneous impact force to a certain extent, which helps to improve the service life of the die and the quality stability of the stamped products.

[0083] The implementation principle of the above embodiment is as follows: After the metal coil is flattened, it is conveyed from one end of the mold to the other end under power drive. Each part of the mold punches the coil in sequence, and finally completely punches it into the shape of the part. During the stamping process, the first punching mechanism 4 and the second punching mechanism 5 realize the punching of holes, the initial bending mechanism 6, the bending and punching mechanism 7, and the two side bending mechanisms 8 realize the bending of the workpiece, the drilling mechanism realizes the drilling of the top and side walls of the workpiece, and finally the cutting mechanism cuts the stamped workpiece off the coil. The layout of the entire continuous lower die is reasonable, and the cooperation between the mechanisms is close, ensuring the efficiency and accuracy of the stamping process. At the same time, the first belt assembly 35, the second belt assembly, and the third belt assembly realize the timely transportation and handling of waste materials, avoiding the impact of waste material accumulation on the mold. In addition, the use of special-shaped punches and front-to-back height difference structures in the mold reduces noise and further improves the user comfort and service life of the mold.

[0084] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application.
