Description

Technical Field

[0001] The present invention relates to the technical field of vehicle accessory production, and specifically to a stamping system and a stamping method. Background Art

[0002] As is well known, in the production process of automotive door frame trim products, the production process of the trim products includes: rolling, bending, punching, stamping features, and assembly. In the punching process, a large number of holes need to be opened on an automotive door frame trim product, and the requirements for holes at different positions are different.

[0003] In the current prior art, when processing the trim, single-step processing is adopted, resulting in low production efficiency, a prolonged production cycle, and the cumulative superposition of tolerances in equipment tooling and operation debugging, which cannot guarantee the accuracy of processing. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: The present invention discloses a stamping system and a stamping method to solve the problems of low production efficiency and low accuracy existing in the current stamping of automotive trims.

[0005] To solve the above technical problem, the present invention discloses a stamping system, which includes: A machine table, on which a first mounting plate and a second mounting plate are oppositely arranged. The first mounting plate and the second mounting plate respectively form an angle with the horizontal plane, and a punching mechanism is provided on the first mounting plate and / or the second mounting plate; The punching mechanism includes a body, a punching component, a driving component, and a supporting component. The supporting component is correspondingly arranged with the punching component, and a punching inductor is arranged in the supporting component; wherein, the punching component is slidably connected with the body, the driving component is arranged on the body, and the output end of the driving component is drivingly connected with the punching component. The driving component is used to drive the punching component into the supporting component and detect the relative position of the punching component in the supporting component through the punching inductor.

[0006] In the above technical solution of the present invention, aiming at the problems of low production efficiency and low accuracy existing in the current stamping of automotive trims. The present invention discloses a new stamping system, which optimizes the design of its own structure. It can use the punching inductor arranged in the supporting component to detect whether the punching component punches in place during stamping, reduce the risk of missed punching, and ensure the accuracy of the punching position, so as to provide higher processing accuracy and repeatability, and it is applicable to applications requiring high-precision hole positions.

[0007] In addition, the punching mechanism in the stamping system of the present invention has a relatively simple structure, and its stamping process is stable. It can improve production efficiency while ensuring sufficient durability, being able to withstand long-term use without failure, thereby reducing the later maintenance cost. It has good promotion prospects and application value.

[0008] Furthermore, in the stamping system described in the present invention, the stamping assembly includes a first pressing block, a punching needle, and a second pressing block. The first pressing block and the second pressing block are slidably arranged on the body. One end of the first pressing block is connected to the output end of the driving assembly, and the other end of the first pressing block is connected to the second pressing block through a stamping spring. Wherein, one end of the punching needle is fixedly connected to the first pressing block, and the other end of the punching needle penetrates through the second pressing block.

[0009] In the above technical solution of the present invention, in order to ensure a more stable stamping effect and improve the durability of the punching mechanism during the actual stamping process, in the present invention, a stamping spring is specifically arranged between the first pressing block and the second pressing block, so that the other end of the first pressing block away from the driving assembly is connected to the second pressing block through the stamping spring to avoid rigid contact when the second pressing block contacts the trim to be stamped.

[0010] Correspondingly, in the present invention, one end of the punching needle is fixed on the first pressing block and the other end penetrates through the second pressing block to improve the durability of the punching needle and avoid deformation of the punching needle after multiple stampings, which may affect the accuracy of subsequent stampings.

[0011] Furthermore, in the stamping system described in the present invention, a pressing block is arranged on the side of the second pressing block away from the first pressing block.

[0012] In the above technical solution of the present invention, in the stamping system, when the driving assembly drives the stamping assembly to approach the supporting assembly, the pressing block on the second pressing block can correspondingly press against the product to be stamped to avoid damage to the product to be stamped by the second pressing block during stamping.

[0013] Furthermore, in the stamping system described in the present invention, a punching hole is arranged on the supporting assembly, and the punching hole is arranged corresponding to the punching needle.

[0014] Furthermore, in the stamping system described in the present invention, a trimming mechanism is also arranged on the first mounting plate and / or the second mounting plate, and the trimming structure is arranged in parallel with the punching mechanism.

[0015] Furthermore, in the stamping system described in the present invention, the first mounting plate, the second mounting plate and the upper surface of the machine table enclose a triangle.

[0016] In the above technical solution of the present invention, punching mechanisms can be provided on both the first mounting plate and the second mounting plate. The first mounting plate and the second mounting plate are arranged opposite to each other, and punching mechanisms can be provided on both the first mounting plate and the second mounting plate to treat the stamping products as the first processing station and the second processing station respectively for stamping, so as to realize double-station stamping and effectively improve production efficiency.

[0017] Correspondingly, in some preferred embodiments, the first mounting plate, the second mounting plate and the upper surface of the machine table can be controlled to enclose a triangle. The top edges of the first mounting plate and the second mounting plate can be connected to each other to utilize the stability of the triangle to enhance the mounting stability of the first mounting plate and the second mounting plate and ensure the stability and reliability of the punching mechanisms on the first and second mounting plates during stamping work.

[0018] Furthermore, in the stamping system of the present invention, an electric control mechanism and a hydraulic mechanism are further included. The driving component of the punching mechanism is a hydraulic cylinder. The electric control mechanism is electrically connected to the hydraulic mechanism, and the hydraulic mechanism is connected to the driving component through an oil pipe.

[0019] In the above technical solution of the present invention, in order to improve the durability of the stamping system and reduce subsequent maintenance costs, the driving component can be specifically selected as a hydraulic cylinder, and the hydraulic mechanism can be specifically connected to the driving component through an oil pipe to control the work of the driving component in the form of hydraulic drive by the hydraulic mechanism. Among them, in actual application, the oil pipe connecting the hydraulic mechanism and the driving mechanism can be specifically selected as an oil pipe with a quick connector to facilitate quick replacement according to specific application requirements during use.

[0020] Of course, in some other embodiments, according to the requirements of the actual application scenario, the driving component can also be specifically selected as a driving motor, and the driving motor can also drive the stamping component to approach or away from the supporting component.

[0021] Furthermore, in the stamping system of the present invention, a pressing mechanism is further provided on the first mounting plate and / or the second mounting plate, and the pressing mechanism is at least provided on one side of the first mounting plate and / or the second mounting plate.

[0022] Correspondingly, the present invention also discloses a stamping method, which can be implemented based on the above stamping system of the present invention, and specifically includes the steps: S1: Place the product to be stamped between the stamping component and the supporting component of the punching mechanism; S2: Start the driving component of the punching mechanism to drive the stamping component into the supporting component through the output end of the driving component and punch the product to be stamped; S3: When the stamping inductor detects that the stamping assembly is at a preset position within the support assembly, the output end of the driving assembly resets and drives the stamping assembly away from the support assembly.

[0023] In the above technical solution of the present invention, to avoid missed stamping or incomplete stamping, only when the stamping inductor detects that the stamping assembly is at a preset position within the support assembly, that is, when it is determined that the stamping assembly has penetrated the above-mentioned stamping product, will the output end of the driving assembly be controlled to reset and drive the stamping assembly away from the support assembly to complete the reset.

[0024] Of course, in some preferred embodiments, to obtain a better stamping effect, after the stamping inductor detects that the stamping assembly is at a preset position within the support assembly, the output end of the above-mentioned driving assembly can be controlled to reset only after maintaining pressure for a preset period of time.

[0025] Furthermore, in the stamping method of the present invention, the product to be stamped is placed between the stamping assemblies and the support assemblies of multiple punching mechanisms, and the driving assemblies of multiple punching mechanisms are sequentially activated along the extension direction of the product to be stamped.

[0026] In the above technical solution of the present invention, to improve production efficiency, multiple punching mechanisms can be specifically used to punch the same product to be stamped. That is, on the first mounting plate or the second mounting plate, multiple punching mechanisms can be provided for punching, so as to punch multiple holes after the product to be stamped is positioned.

[0027] Among them, considering that when the product to be stamped is an automotive trim strip, the automotive trim strip has a certain flexibility. To further improve the accuracy of punching the product to be stamped, the driving assemblies of multiple punching mechanisms can be sequentially activated separately along the extension direction of the product to be stamped for punching, so as to avoid the hole position deviation caused by punching multiple holes at one time. For example: along the extension direction of the product to be stamped, the first group of punching mechanisms, the second group of punching mechanisms and the third group of punching mechanisms are sequentially arranged. Each group of punching mechanisms can be provided with an appropriate number of punching mechanisms. After all the punching mechanisms in the first group of punching mechanisms complete the driving punching, the control makes all the punching mechanisms in the second group of punching mechanisms complete the driving punching, and finally the third group of punching mechanisms are driven for the final driving punching to ensure the punching accuracy to the greatest extent.

[0028] The beneficial effects of the present invention are as follows: The stamping system of the present invention can conveniently and effectively punch holes in automotive trim strips. Compared with existing traditional stamping methods, the stamping system has optimized the design of its own structure. It can use the stamping sensors provided in the support component to detect whether the stamping component is in place during stamping, reduce the risk of missed punching, and ensure the accuracy of the punching position. It can provide higher processing accuracy and repeatability, and is suitable for applications that require high-precision hole positions. At the same time, the punching mechanism adopted by the stamping system of the present invention has a relatively simple structure, and its stamping process is stable. It can improve production efficiency while ensuring sufficient durability to withstand long-term use without failure, reducing the later maintenance cost.

[0029] Correspondingly, the above stamping method of the present invention can be implemented based on the above stamping system of the present invention, and it also has the above advantages and beneficial effects. Brief Description of the Drawings

Detailed implementation manners

[0044] To describe in detail the technical content, achieved objectives and effects of the present invention, the following is described in conjunction with the embodiments and with reference to the drawings.

[0045] It is found through research that in the current prior art, the production cycle of products produced by existing stamping equipment is long. They all adopt single-step processing, and the processed hole positions are prone to fluctuations during production, and it is impossible to detect in real time whether they are in place, seriously affecting the product yield and production efficiency.

[0046] Based on this, please refer to Figures 1 to 13, the present invention discloses a new stamping system for the punching process of automotive trim strips. Among them, in this embodiment, the stamping system specifically includes a machine table 7, an electric control mechanism 8, a hydraulic mechanism 9, and a first mounting plate 5 and a second mounting plate 6 provided on the machine table 7. Moreover, the above-mentioned first mounting plate 5 and second mounting plate 6 respectively form an angle with the horizontal plane, and the first mounting plate 5, the second mounting plate 6 and the upper surface of the machine table 7 enclose a triangle, so as to be provided with a plurality of punching mechanisms on the above-mentioned first mounting plate 5 and second mounting plate 6 at the same time, and use these punching mechanisms to punch the product 2 to be stamped.

[0047] In the stamping system of the present invention, the product 2 to be stamped can be specifically selected as products such as a stamping vehicle exterior integrated door frame trim strip, upper and lower window decorative strips, front and rear triangular window trim strips, etc.

[0048] See Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment, the punching mechanism designed by the present invention can specifically include: a body 1, a punching assembly 11, a driving assembly 13 and a supporting assembly 12. Among them, the punching assembly 11 and the supporting assembly 12 are correspondingly arranged on the body 1, and the two can be specifically fixed on the above-mentioned body 1 through a double-slider linear slide rail, and a punching inductor 122 is arranged in the supporting assembly 12; in actual application, the punching assembly 11 is slidably connected to the body 1, the above-mentioned driving assembly 13 is arranged on the body 1, the punching assembly 11 is drivingly connected to the output end of the driving assembly 13, and the above-mentioned driving assembly 13 can be used to drive the punching assembly 11 into the supporting assembly 12, and detect the relative position of the punching assembly 11 in the supporting assembly 12 through the above-mentioned punching inductor 122.

[0049] That is to say, in the actual use process, the product to be stamped can be correspondingly placed between the punching assembly 11 and the supporting assembly 12 of the punching mechanism, so as to provide support for the product 2 to be stamped by the supporting assembly 12 when the punching assembly 11 performs punching. Among them, by adjusting the position and structure of the punching assembly 11, the product 2 to be stamped in the same batch can be stably punched, and the punching efficiency can be guaranteed.

[0050] And, see Figure 1 As shown, in the stamping system of the present invention, the driving assembly 13 of the punching mechanism can be specifically selected as a hydraulic cylinder, the hydraulic mechanism 9 can be specifically selected as a hydraulic station, and the electric control mechanism 8 can be specifically selected as an electrical cabinet; among them, the above-mentioned electrical cabinet is controlled to be electrically connected to the hydraulic station, and the hydraulic station is connected to the driving assemblies 13 of all the punching mechanisms on the first mounting plate 5 and / or the second mounting plate 6 through oil pipes, so as to control the driving assembly 13 of the punching mechanism to work or reset by using the hydraulic driving form through the operation of the electric control hydraulic station, and its cost is low and the stability is strong.

[0051] Of course, in some other embodiments, according to the requirements of the actual application scenario, the above-mentioned driving component 13 can also specifically select a driving motor, which can also drive the above-mentioned stamping component 11 to approach or move away from the supporting component 12.

[0052] It can be seen that in the stamping system designed by the present invention, the stamping system has optimized the design of its own structure. It can use the stamping inductor 122 arranged in the supporting component 12 to detect whether the stamping component 11 is in place during stamping, reduce the risk of missed punching, and ensure the accuracy of the punching position, so as to provide higher processing accuracy and repeatability. At the same time, the punching mechanism in the stamping system of the present invention has a relatively simple structure, and its stamping process is stable. It can improve production efficiency while ensuring sufficient durability, being able to withstand long-term use without failure, and reducing the later maintenance cost.

[0053] Correspondingly, as Figure 4 、 Figure 5 shown, in this embodiment, the stamping component 11 of the punching mechanism designed by the present invention can specifically include: a first pressing block 111, a punching needle 113 and a second pressing block 112; the above-mentioned first pressing block 111 and the second pressing block 112 are sequentially distributed along the first direction and are slidably connected to the main body 1; the above-mentioned first pressing block 111 is arranged at the output end of the driving component 13, and a stamping spring 114 is arranged between the first pressing block 111 and the second pressing block 112; the punching end 1132 of the punching needle 113 penetrates the second pressing block 112 along the first direction, and the fixed end 1131 of the punching needle 113 is connected to the first pressing block 111.

[0054] In this embodiment, the punching needle 113 in the stamping component 11 has a fixed end 1131 and a punching end 1132. The fixed end 1131 is detachably connected to the first pressing block 111, which is convenient for replacing punching needles 113 of different specifications according to needs. The punching end 1132 of the punching needle 113 passes through the second pressing block 112, that is, the second pressing block 112 is sleeved on the punching needle 113 and is slidably connected to the main body 1. The stamping spring 114 between the second pressing block 112 and the first pressing block 111 enables the second pressing block 112 to slide together with the first pressing block 111, and after the second pressing block 112 abuts against the product 2 to be stamped placed on the supporting component 12, the first pressing block 111 can continue to slide, thereby pushing the punching needle 113 to continue to move, punching the product 2 to be stamped, and then the punching needle 113 enters the supporting component 12. Based on such a setting, it can be ensured that during actual punching, the above-mentioned second pressing block 112 can abut against the product 2 to be stamped to limit the position of the product 2 to be stamped, and enable the punching needle 113 to continue to act driven by the first pressing block 111, thereby completing the punching action.

[0055] Preferably, when the stamping spring 114 is not compressed, the stamping end 1132 of the punch pin 113 is received within the second pressure block 112 or flush with the lower surface of the second pressure block 112. Such an arrangement can protect the punch pin 113 and prevent the stamping end 1132 of the punch pin 113 from colliding with external objects.

[0056] In addition, referring to Figure 5 As shown, in this embodiment, in the stamping assembly 11, a movable pin 116 is provided between the second pressure block 112 and the first pressure block 111. The movable pin 116 is used to ensure that the positions of the second pressure block 112 and the first pressure block 111 in the first direction do not shift, ensuring the accuracy of punching.

[0057] Correspondingly, to obtain a better implementation effect, in this embodiment, a pressure material block 117 is further provided on the side of the second pressure block 112 away from the first pressure block 111 (refer to Figure 6 ). Among them, the shape of the pressure material block 117 can be adjusted according to the shape and specifications of the product 2 to be stamped, so as to ensure the fixing effect on the product 2 to be stamped and save costs. Moreover, the punching mechanism can be adapted to products 2 to be stamped with different specifications.

[0058] Further referring to Figures 6 to 9 As shown, in this embodiment, a stamping hole 121 is specifically provided on the support assembly 12. The stamping hole 121 is specifically a punch sleeve, and the stamping hole 121 is arranged corresponding to the punch pin 113. Among them, the stamping hole 121 is opened on the support assembly 12, and the center of the stamping hole 121 is on the central axis of the punch pin 113. After the punch pin 113 is displaced, the stamping end 1132 can enter the stamping hole 121, ensuring the punching effect while protecting the stamping end 1132 of the punch pin 113 and extending the service life of the punch pin 113.

[0059] Of course, in this embodiment, a stamping inductor 122 can also be specifically arranged in the stamping hole 121 to determine whether the punch pin 113 is operating normally by detecting the distance that the stamping end 1132 extends into or detecting whether the stamping end 1132 reaches a set position, so as to determine whether the punching action is proceeding normally. Specifically, the stamping inductor 122 can adopt a photoelectric sensor or an ultrasonic sensor, etc. Those skilled in the art can select a suitable stamping inductor 122 according to actual needs.

[0060] In addition, to improve the durability of the above punching mechanism, in this embodiment, a guide post 115 is provided on the side of the second pressure block 112 away from the first pressure block 111. The support assembly 12 includes a guide hole, and the guide hole is arranged corresponding to the guide post 115. The cooperation of the guide post 115 and the guide hole can ensure that the second pressure block 112 can be aligned with the support assembly 12 during punching, ensuring the accuracy of punching.

[0061] In addition, to ensure the effective positioning of the product 2 to be punched on the above-mentioned support component 12, the user can position it according to the punching requirements when placing the product 2 to be punched. Specifically, a positioning pin can be used for positioning, and a positioning detection device, such as a proximity switch, can also be provided on the support component 12 to effectively determine whether the position of the product 2 to be punched is correct and eliminate the errors generated by the staff during production and placement.

[0062] It should be noted that in principle, no further debugging is required after the positioning of the product 2 to be punched is completed. However, the product 2 to be punched will deform after punching. Therefore, in some specific factual situations, it is necessary to adjust the height support of the product 2 to be punched. For example, a profiling support block can be set to support the product 2 to be punched, and its height can be adjusted by gaskets in the vertical height direction. The minimum gasket thickness is 0.1 mm, and the gasket thickness specifications can be specifically controlled as 0.1 mm, 0.2 mm, 0.5 mm, 1 mm or 2 mm.

[0063] Of course, when actually adjusting the position of the punched product 2, the positions of the product 2 to be punched in the horizontal length direction, horizontal width direction and vertical height direction can all be adjusted by gaskets. The user can reasonably adjust the positioning position of the product 2 to be punched according to specific usage requirements.

[0064] At the same time, in actual application, the punching mechanism can also adjust the stroke of the output end of its own drive component 13 according to the punching requirements of different products 2 to be punched, so as to control the stroke adjustment amount of the output end in the first direction to be ±15 mm; in actual application, the stroke of the drive component 13 can be adjusted by using a nut in cooperation with a setscrew. To ensure the stability of the size and hole diameter of the product 2 to be punched after punching, the gap between the product 2 to be punched and the punching mechanism during punching also needs to be reduced. Specifically, the gap can be ensured to be less than 0.1 mm, and the minimum cylinder diameter of the drive component 13, which is a hydraulic cylinder, can be specifically controlled to be 32 mm, and its cylinder diameter can be specifically selected from 32 mm to 100 mm; and, the hydraulic cylinder is also equipped with a magnetic switch for in-place detection.

[0065] Correspondingly, in this embodiment, in order to improve production efficiency, multiple punching mechanisms can be specifically used to punch the same product 2 to be punched. That is, on the first mounting plate 5 or the second mounting plate 6, multiple punching mechanisms can be provided for punching. After the product 2 to be punched is positioned, multiple holes are punched. Specifically, it includes the steps: S1: Place the product 2 to be punched between the punching component 11 and the support component 12 of the punching mechanism; S2: Activate the electric control mechanism 8, so that the electric control mechanism 8 controls the start of the above-mentioned hydraulic mechanism 9 through an electric signal. The hydraulic mechanism 9 supplies liquid to the driving component 13 of the punching mechanism and activates the driving component 13, so as to drive the stamping component 11 into the support component 12 through the output end of the driving component 13 and punch the product 2 to be stamped. S3: When the stamping sensor 122 detects that the stamping component 11 is at a preset position in the support component 12, after maintaining pressure for a preset period of time, the output end of the driving component 13 of the punching mechanism resets and drives the stamping component 11 away from the support component 12, facilitating the user to take out the product 2 to be stamped.

[0066] Among them, considering that when the product 2 to be stamped is an automotive trim strip, the automotive trim strip has a certain flexibility. To further improve the punching accuracy of the product 2 to be stamped, the driving components 13 of multiple punching mechanisms can be sequentially activated along the extension direction of the product 2 to be stamped for punching, avoiding the hole position deviation caused by punching multiple holes at one time.

[0067] For example: along the extension direction of the product 2 to be stamped, a first group of punching mechanisms, a second group of punching mechanisms, and a third group of punching mechanisms are sequentially arranged. Each group of punching mechanisms can be provided with an appropriate number of punching mechanisms. After all the punching mechanisms in the first group of punching mechanisms complete the driving punching, control all the punching mechanisms in the second group of punching mechanisms to complete the driving punching, and finally drive the third group of punching mechanisms for the final driving punching to ensure the punching accuracy to the greatest extent.

[0068] It should be noted that as Figure 10 shown, in this embodiment, a trimming mechanism 3 can also be installed on the first mounting plate 5 and the second mounting plate 6. The trimming mechanism 3 is arranged in parallel with the punching mechanism. The trimming mechanism 3 cuts the product 2 to be stamped, enabling the punching tooling to have the capabilities of punching and cutting as a whole, enhancing the overall applicable range of the device, further saving production time, and improving production efficiency.

[0069] Specifically, as Figure 12 and Figure 13As shown in the figure, the trimming mechanism 3 as a whole adopts the same structure as the stamping mechanism. The difference is that the punching pin 113 is replaced with a trimming blade 313 as required, and the size of the structure is increased to make the structure adapt to the action requirements of trimming. The trimming mechanism 3 includes a trimming body 31, a first trimming pressing block 311, a trimming blade 313, a second trimming pressing block 312, a trimming support 32 and a trimming driving member 33. The first trimming pressing block 311 and the second trimming pressing block 312 are sequentially distributed along the first direction and are slidably connected to the trimming body 31 through a double-slider linear slide rail; the first trimming pressing block 311 is arranged at the output end of the trimming driving member 33, and a buffer spring is provided between the first trimming pressing block 311 and the second trimming pressing block 312; the trimming end of the trimming blade 313 penetrates through the second trimming pressing block 312 along the first direction, and the fixed end of the trimming blade 313 is connected to the first trimming pressing block 311. A trimming hole 321 is provided on the trimming support 32, the trimming hole 321 is arranged corresponding to the trimming blade 313, and a trimming inductor is arranged in the trimming hole 321. Those skilled in the art can adjust the shapes of the components of the trimming mechanism 3 according to actual needs to make the trimming mechanism 3 adapt to the trimming requirements of products of different specifications, and no specific limitation is made.

[0070] In addition, as Figure 11 shown, in this embodiment, a pressing assembly 4 is further provided on the above-mentioned first mounting plate 5 and second mounting plate 6. When the product 2 to be stamped is placed on the body 1, the pressing assembly 4 is used to pre-press the product 2 to be stamped, ensuring that the product 2 to be stamped does not displace before the punching action, thereby ensuring the product yield and reducing the possibility of refraction of the product 2 to be stamped. Specifically, an extended support seat 14 is further provided on the trimming mechanism 3 at the end. Before performing the punching and cutting action, the two ends of the product 2 to be stamped are respectively arranged on the corresponding extended support seats 14, and the two ends of the product 2 to be stamped are pre-pressed by the pressing assembly 4, and then the punching and cutting action is performed. Optionally, the pressing assembly 4 can adopt structures such as a clamp or a jaw, as long as it can fix the product 2 to be stamped, and no specific limitation is made.

[0071] As Figures 1 to 13As shown in the figure, the specific working principle of the punching system provided by the present invention is as follows: The operator places the product 2 to be punched on the support assembly 12 and uses the pressing assembly 4 to fix the product 2 to be punched. After the fixing is completed, the punching operation starts. The driving assembly 13 pushes the first pressing block 111 to slide, and the second pressing block 112 slides together with the first pressing block 111 under the action of the punching spring 114. After the second pressing block 112 abuts against the product 2 to be punched placed on the support assembly 12, the second pressing block 112 presses the product 2 to be punched. Then the first pressing block 111 continues to slide, pushing the punching needle 113 to continue to move, and the punching end 1132 punches the product 2 to be punched. The punching end 1132 enters the punching hole 121, and the punching sensor 122 detects that the punching end 1132 reaches the set position, indicating that the punching operation is completed. After the punching is completed, the driving assembly 13 drives the first pressing block 111 to return to its original position, so that the punching assembly 11 as a whole returns to its original position. Then the operator opens the pressing assembly 4 and takes out the punched product. If the punching sensor 122 detects that the punching end 1132 does not reach the set position, the punching sensor 122 gives an alarm to remind the operator to check, reducing the defective rate.

[0072] In summary, the punching system and punching method of the present invention have the following advantages: The punching system of the present invention can punch the automotive trim strip conveniently and effectively. Compared with the existing traditional punching means, the punching system has optimized the design of its own structure. It can use the punching sensor 122 provided in the support assembly 12 to detect whether the punching assembly 11 punches in place during punching, reducing the risk of missed punching and ensuring the accuracy of the punching position, so as to provide higher processing accuracy and repeatability.

[0073] At the same time, the punching mechanism adopted by the punching system of the present invention has a relatively simple structure, and its punching process is stable. It can improve the production efficiency while ensuring its own sufficient durability to withstand long-term use without failure, thereby reducing the replacement and maintenance costs.

[0074] In addition, the first mounting plate 5 and the second mounting plate 6 are provided in the punching system of the present invention. Punching mechanisms can be provided on both of these mounting plates to punch multiple products 2 to be punched in the form of double-station processing, improving its production efficiency, reducing the punching cycle time, and increasing the output.

[0075] At the same time, the punching system of the present invention can use multiple punching mechanisms to punch the same product 2 to be punched. It has a high degree of automation and strong adaptability. It can be applied to trim strips of different specifications and shapes to meet the needs of different products. It has good production benefits, good promotion prospects and application value. And in actual application, other products can also be switched for production to save equipment costs.

[0076] The above are only embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in the related technical fields, shall be similarly included in the patent protection scope of the present invention.
