Description

Technical Field

[0001] This invention belongs to the field of punching device technology, specifically relating to an electronic detection mechanism for punching dies and a punching die. Background Technology

[0002] In the automotive manufacturing industry, door frame exterior water-cutting products are critical sealing and decorative components, and their punching accuracy directly affects the overall vehicle assembly quality and appearance consistency. To ensure the accuracy of punching dimensions and effectively prevent assembly defects such as missed processes, the industry commonly integrates electronic error-proofing detection mechanisms into the molds. These mechanisms typically monitor in real time whether the workpiece is in place and whether the punching position is accurate, and feed the signal back to the control system, thereby achieving automated error prevention.

[0003] However, in existing technologies, such electronic inspection devices mostly employ fixed wiring, directly connecting the inspection wires to the support components (structural components used for positioning or limiting workpieces) mounted on the mold frame. Since the support components need a rigid connection to the mold frame to ensure positioning accuracy, and the electronic inspection circuitry must be laid out along with the support components, the entire inspection system lacks modularity and detachability. This problem is particularly pronounced when applied to 25-ton small punch presses: due to the limited internal space of the punch press, operators cannot directly adjust the support components inside the press; each time adjustments are made or product models are changed, the entire mold set must be pulled out of the punch press using a trolley, and the position of the support components and the wiring connections must be checked in the external working area. This process is not only cumbersome and time-consuming, significantly increasing the difficulty of debugging and labor costs, but also severely slows down the production cycle and reduces the overall equipment efficiency (OEE).

[0004] Furthermore, traditional wiring methods are prone to wire wear, poor contact, and even breakage during frequent mold assembly and disassembly, further affecting the reliability and lifespan of the testing system. Therefore, there is an urgent need for an electronic testing mechanism that is compact, easy to install and disassemble quickly, and capable of automatic power on / off, to solve the problems of inconvenient debugging and low production efficiency caused by space limitations and fixed wiring in existing technologies. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an electronic inspection mechanism for punching dies and a punching die, in view of the current state of the prior art.

[0006] The technical solution adopted by this invention to solve the above-mentioned technical problem is as follows: An electronic inspection mechanism for a punching die is proposed, wherein the punching die includes a support base and a punching station detachably connected to the support base, and the electronic inspection mechanism includes:

[0007] A socket assembly, which is disposed on the support base and includes a first conductive block electrically connected to an external power source;

[0008] A detection unit is disposed on the punching station. The detection unit includes a detection element and a second conductive block electrically connected to the detection element. The detection element is used to detect the workpiece to be processed on the punching station.

[0009] The second conductive block is configured such that when the punching station is fixed on the support, it contacts the first conductive block to conduct power to the detection component; when the punching station is separated from the support, the second conductive block separates from the first conductive block, causing the detection unit to detach from the socket assembly along with the punching station.

[0010] In the above-mentioned electronic inspection mechanism for punching dies, the first conductive block is movably disposed on the socket assembly, and the socket assembly further includes an elastic member that abuts against the first conductive block;

[0011] The first conductive block has a natural state and a compressed state;

[0012] When the detection unit is separated from the socket assembly, the elastic element pushes the first conductive block to reset to the natural state, so that the first conductive block is located on the movement path of the second conductive block;

[0013] When the punching station is installed on the support base and moves the detection unit toward the socket assembly, the second conductive block contacts and pushes the first conductive block to overcome the resistance of the elastic element and enter the compressed state. At this time, the elastic element stores energy and generates a rebound force that causes the first conductive block and the second conductive block to press against each other.

[0014] In the aforementioned electronic inspection mechanism for a punching die, the moving direction of the first conductive block is perpendicular to the installation direction of the punching station and the support base.

[0015] In the aforementioned electronic inspection mechanism for punching dies, the power supply component further includes:

[0016] A first support platform, with one end of the elastic element connected to the first support platform and the other end connected to the first conductive block;

[0017] Mounting blocks are provided on both sides of the first support platform along the moving direction of the first conductive block, and a guide groove is formed between the two mounting blocks. The first conductive block is movably disposed in the guide groove.

[0018] In the aforementioned electronic inspection mechanism for punching dies, the mounting block is made of conductive metal material, and the mounting block is provided with mounting holes for connecting wires;

[0019] The socket assembly further includes an insulating seat disposed between the first support platform and the support base, the insulating seat covering at least a portion of the surface of the first support platform to achieve electrical insulation between the socket assembly and the support base.

[0020] In the above-mentioned electronic inspection mechanism for punching dies, the first support platform is provided with a mounting part, and the insulating base is provided with a first connecting part that is embedded in the mounting part;

[0021] The mounting part is provided with a first insulating pad at the end away from the support base, and the first insulating pad is provided with a stepped hole;

[0022] The bolts pass through the stepped hole and the first connecting part in sequence and are threaded to the support base to achieve an insulated connection between the first support platform and the support base.

[0023] In the above-mentioned electronic inspection mechanism for punching dies, the inspection unit includes a second support platform, which is detachably connected to the punching station. The inspection piece is installed on the second support platform to provide support for the inspection piece.

[0024] In the above-mentioned electronic inspection mechanism for punching dies, the second conductive block includes a conductive part bent to form an angle and a second connecting part;

[0025] The first end of the conductive part is in movable contact with the first conductive block, and the second end of the conductive part is electrically connected to the detection element;

[0026] The second connecting part is fixed to the second support platform, and a second insulating pad is provided between the two.

[0027] In the above-mentioned electronic inspection mechanism for punching dies, the second support platform is provided with a waist-shaped hole, and a bolt passes through the waist-shaped hole and is connected to the punching station. The waist-shaped hole is used to adjust the installation position of the inspection unit on the punching station.

[0028] In addition to solving the above-mentioned technical problems, the present invention also proposes a punching die, including the above-mentioned electronic inspection mechanism for punching dies.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] (1) By setting the socket assembly on the support base and the detection unit on the detachable punching station, and by using the contact electrical connection between the first conductive block and the second conductive block, the power supply of the detection unit is automatically connected and disconnected. The design avoids the problems of cable tangling, wear and inconvenience of connection caused by traditional fixed wiring, and significantly improves the convenience of mold replacement and backing component debugging. It is especially suitable for small punching machine environments with limited space.

[0031] (2) By incorporating a movable first conductive block and an elastic element in the socket assembly, the structure possesses self-adjusting capabilities. During installation at the punching station, the second conductive block compresses the elastic element, ensuring reliable clamping contact between the two conductive blocks. After disassembly, the elastic element automatically resets the first conductive block, ensuring it is in the correct mating position for the next installation. This design not only significantly improves the stability and contact reliability of the electrical connection but also effectively compensates for assembly tolerances, avoiding poor contact caused by minor misalignments. Furthermore, it enhances the self-alignment performance of the mechanism and further simplifies mold debugging and maintenance operations.

[0032] (3) The moving direction of the first conductive block is set to be perpendicular to the installation direction of the punching station and the support base, so that the conductive block can float elastically in the vertical direction. This layout makes full use of the space in the height direction of the mold, avoids occupying valuable horizontal installation space in the narrow punch press, is more suitable for the compact mold cavity structure of the 25-ton punch press, and is conducive to the optimization of the overall layout.

Detailed Implementation

[0040] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0041] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0042] like Figures 1 to 6 As shown, the present invention provides an electronic inspection mechanism 300 for a punching die. The punching die includes a support base 100 and a punching station 200 detachably connected to the support base 100, and the electronic inspection mechanism 300 includes a socket assembly 310 disposed on the support base 100 and an inspection unit 320 disposed on the punching station 200.

[0043] Specifically, the socket assembly 310 is fixed on the support base 100, and its interior is provided with a first conductive block 311 that is electrically connected to an external power source.

[0044] The detection unit 320 is installed on the punching station 200 and includes a detection element 321 (such as a proximity switch, photoelectric sensor or micro switch, etc.) for sensing the presence, position or state of the workpiece, and a second conductive block 322 electrically connected to the detection element 321.

[0045] The specific type of inspection component 321 can be flexibly selected according to the material, structural characteristics and automation level of the automotive door frame outer water-cutting product to meet different error prevention and inspection needs.

[0046] The key is that the second conductive block 322 is designed such that when the punching station 200 is installed and fixed to the support base 100, it drives the second conductive block 322 to make contact with the first conductive block 311, thereby automatically turning on the power to the test piece 321.

[0047] When the punching station 200 is removed from the support base 100, the second conductive block 322 separates from the first conductive block 311, the power supply is automatically disconnected, and the entire detection unit 320 is detached from the socket assembly 310 along with the punching station 200.

[0048] This "plug-and-play, disconnect-and-go" electrical connection method eliminates the need for traditional fixed wiring structures, effectively avoiding problems such as cable tangling, wear and tear, and difficulty in plugging and unplugging.

[0049] The core idea of ​​this design is to fix the socket assembly 310 on the support base 100, and integrate the detection unit 320 into the detachable punching station 200, and realize the power supply switching through the elastic connection between the first conductive block 311 and the second conductive block 322.

[0050] Because it uses a contact-type electrical connection, there is no need to plug or unplug additional wires or interfaces. The power can be automatically switched on and off during the loading and unloading process at the punching station 200, which greatly improves the ease of operation. Especially in small punch presses with limited space, such as 25-ton presses, this structure significantly reduces the difficulty of debugging the backing components and the mold change time, thereby improving the production cycle and equipment utilization rate.

[0051] In addition, the detachable connection between the punching station 200 and the support base 100 can be achieved through a mechanical limiting structure.

[0052] For example, at least one receiving groove with an opening is provided on the support 100, and one or more locking blocks are threadedly connected thereto.

[0053] During installation, the punching station 200 is embedded in the receiving groove, and its freedom of movement is restricted by tightening the locking block; during disassembly, simply loosen the locking block and pull out the punching station 200 in the opposite direction of the installation direction 500.

[0054] This connection method has a simple structure and reliable positioning. It works in conjunction with the electronic testing mechanism 300, further enhancing the modularity and maintenance efficiency of the entire mold system.

[0055] It is worth mentioning that the first conductive block 311 and the second conductive block 322 are designed with full consideration of the reliability and durability of electrical contact in terms of structure and materials, so as to ensure stable power conduction in the lap state. Both are usually made of metal materials with high conductivity, wear resistance and oxidation resistance, such as copper alloys (such as phosphor bronze, brass) or stainless steel with silver / gold plating, which not only ensures low contact resistance, but also has good elasticity and fatigue resistance.

[0056] The electrical connection between the second conductive block 322 and the detection element 321 adopts a direct, low-impedance physical contact method to ensure stable signal or power transmission.

[0057] In terms of specific structure, the second conductive block 322 is integrally bent from a metal material with excellent conductivity (such as phosphor bronze or brass), and one end of it extends to form a terminal for electrical connection detection element 321.

[0058] The terminal can achieve a reliable electrical connection with the detection element 321 in any of the following ways: First, the lead wire of the detection element 321 is fixed to the reserved connection point of the second conductive block 322 by crimping or welding; Second, a threaded hole or insertion slot is provided on the second conductive block 322, and the electrode pin of the detection element 321 is directly inserted and locked with screws or elastically clamped.

[0059] Regardless of the form used, the connection points are located inside or in the protected area of ​​the second support platform 323 to avoid external interference or oil erosion during the stamping process.

[0060] To ensure that the first conductive block 311 and the second conductive block 322 can be tightly abutted when the punching station 200 is fixed on the support base 100, and to avoid poor contact, in a preferred embodiment, the first conductive block 311 is movably disposed on the socket assembly 310, and an elastic element 312 is provided between the first conductive block 311 and the socket assembly 310 for applying a pre-tightening force.

[0061] The first conductive block 311 has a natural state and a compressed state:

[0062] When the detection unit 320 is separated from the socket assembly 310, the elastic element 312 pushes the first conductive block 311 back to its natural state, so that it is located on the movement path of the second conductive block 322;

[0063] When the punching station 200 is installed on the support base 100 and drives the detection unit 320 to move toward the socket assembly 310, the second conductive block 322 contacts and pushes the first conductive block 311, overcoming the resistance of the elastic member 312 and entering the pressure state.

[0064] At this time, the elastic element 312 is compressed and stores energy, and generates a rebound force that causes the first conductive block 311 and the second conductive block 322 to come into close contact, thereby ensuring a stable and reliable electrical connection.

[0065] Preferably, the elastic element 312 is a spring; the contact end of the second conductive block 322 is provided with a chamfer or guide chamfer, which facilitates the smooth transition of the first conductive block 311 from the natural state to the compressed state during the installation process at the punching station 200, thereby reducing assembly resistance and improving docking accuracy.

[0066] By providing a movable first conductive block 311 and an elastic element 312 in the socket assembly 310, the structure is made capable of adaptive adjustment.

[0067] During the installation process at the punching station 200, the second conductive block 322 pushes the first conductive block 311 to compress the elastic element 312, achieving reliable pressing contact between the first conductive block 311 and the second conductive block 322; after disassembly, the elastic element 312 automatically resets the first conductive block 311, ensuring that it is in the correct docking position during the next installation.

[0068] This design not only significantly improves the stability and reliability of electrical connections, but also effectively compensates for assembly tolerances, avoids poor contact caused by minor misalignments, enhances the self-alignment performance of the mechanism, and further simplifies mold debugging and maintenance operations.

[0069] In another preferred embodiment, the movement direction 400 of the first conductive block 311 is perpendicular to the installation direction 500 of the punching station 200 and the support 100.

[0070] Reference Figure 2 The installation direction 500 is parallel to the horizontal direction, while the movement direction 400 of the first conductive block 311 is parallel to the vertical direction, and the two are perpendicular to each other. This arrangement allows the first conductive block 311 to float elastically in the vertical direction.

[0071] This layout makes full use of the space in the height direction of the mold, avoiding the occupation of valuable horizontal installation area inside the small punch press. It is especially suitable for the compact mold cavity structure of a 25-ton small punch press, which is conducive to the compactness of the overall structure and the optimization of the layout.

[0072] Furthermore, the plug-in components also include:

[0073] The first support platform 313, one end of the elastic member 312 is connected to the first support platform 313, and the other end is connected to the first conductive block 311;

[0074] Mounting blocks 314 are provided on both sides of the first support platform 313 along the moving direction 400 of the first conductive block 311. A guide groove 315 is formed between the two mounting blocks 314, and the first conductive block 311 is movably disposed in the guide groove 315.

[0075] The first support platform 313 serves as the main support structure of the socket assembly 310. Its connection with one end of the elastic member 312 can be achieved by setting holes on the first support platform 313 that match the size of the elastic member 312.

[0076] Mounting block 314 not only provides movement support and guidance for the first conductive block 311, but also ensures that the first conductive block 311 will not tilt or get stuck when subjected to force. The mounting block 314 and the first support platform 313 can be fixed by welding, threaded connection or tight fit.

[0077] In this design, a stable guiding and supporting structure is provided for the first conductive block 311 by setting a first support platform 313, an elastic element 312, and mounting blocks 314 with guide grooves 315 on both sides.

[0078] The guide groove 315 precisely defines the movement trajectory of the first conductive block 311, preventing it from deviating or getting stuck during operation, thereby ensuring the repeatability of each insertion action and the reliability of electrical contact.

[0079] This design not only extends the service life of the electronic inspection mechanism 300 but also enhances its operational stability, making the entire system more reliable and durable. Such structural optimization is crucial for ensuring the long-term stable operation of the electronic inspection system in high-frequency stamping equipment.

[0080] Mounting block 314 is made of conductive metal material and has mounting holes 314a for connecting wires.

[0081] The socket assembly 310 also includes an insulating seat 316 disposed between the first support platform 313 and the support base 100, the insulating seat 316 covering at least a portion of the surface of the first support platform 313 for achieving electrical insulation between the socket assembly 310 and the support base 100.

[0082] Specifically, the mounting block 314 is preferably made of a metal material with good electrical conductivity and high mechanical strength, such as brass, phosphor bronze or stainless steel, which can serve as both a structural support and a conductive path.

[0083] Mounting block 314 is provided with mounting hole 314a for connecting external power supply wires. Mounting hole 314a is usually a through hole or countersunk hole with internal thread.

[0084] External wires can be crimped or twisted and then secured in the mounting hole 314a with screws, thereby achieving a low contact resistance and high reliability electrical connection.

[0085] This integrated design eliminates the need for additional terminals, simplifies the wiring structure, and utilizes the conductivity of the metal mounting block 314 itself to stably conduct current to the elastic element 312 and the first conductive block 311, providing a continuous and reliable power supply for the detection unit 320.

[0086] By using a mounting block 314 made of conductive metal material as a wire connection terminal and adding an insulating seat 316 between the first support platform 313 and the support base 100, not only is it ensured that external power can be reliably introduced into the socket assembly 310 through the mounting block 314, but it also effectively achieves electrical isolation between the socket assembly 310 and the metal mold frame (i.e., the support base 100), avoiding safety hazards caused by grounding short circuits or leakage, and significantly improving the safety and electromagnetic compatibility of the entire electronic testing mechanism 300.

[0087] In order to achieve an insulating connection between the second support platform 323 and the support base 100, in this solution, a mounting part 313a is provided on the first support platform 313, and a first connecting part 316a is provided on the insulating base 316 to be embedded in the mounting part 313a.

[0088] A first insulating pad 317 is provided at the end of the mounting part 313a away from the support base 100. The first insulating pad 317 has a stepped hole. The bolt passes through the stepped hole and the first connecting part 316a in sequence, and is finally threaded to the support base 100, thereby achieving an insulating connection between the first support platform 313 and the support base 100.

[0089] Both the insulating base 316 and the first insulating pad 317 are made of engineering plastics or composite insulating materials (such as PBT, PEEK or bakelite) with high insulation, pressure resistance and oil resistance to adapt to the harsh working conditions such as high frequency vibration, oil mist and temperature change in the stamping environment.

[0090] Specifically, the insulating base 316 is located between the first support platform 313 and the support base 100, covering at least part of the outer surface of the first support platform 313, forming an effective electrical isolation barrier to prevent the socket assembly 310 from conducting with the grounded mold frame (i.e., the support base 100) through the metal support structure, thereby avoiding the risk of short circuit or leakage.

[0091] The first insulating pad 317 is located at the end of the first support platform 313 away from the support base 100. The stepped hole on it not only facilitates the insertion of the bolt head but also further enhances the insulation effect, ensuring that the entire socket assembly 310 maintains reliable electrical insulation performance while being mechanically fixed. The two work together to ensure the stability of the structural connection and achieve multi-level electrical isolation, significantly improving the safety and long-term operational reliability of the electronic testing mechanism 300 in stamping production.

[0092] By providing an mounting part 313a on the first support platform 313, and cooperating with the first connecting part 316a on the insulating seat 316 and the stepped hole structure on the first insulating pad 317, an insulating fastening connection between the support platform and the support seat 100 is achieved using bolts.

[0093] This connection method is compact and robust, while further enhancing insulation performance through the first insulating pad 317, ensuring stable electrical isolation even in high-frequency vibration stamping environments, thereby improving the overall reliability of the system. This not only simplifies installation but also improves system stability and durability, making it particularly suitable for small stamping press environments with limited space.

[0094] In order to support and position the detection unit 320, the detection unit 320 includes a second support platform 323, which is detachably connected to the punching station 200. The detection piece 321 is installed on the second support platform 323 to provide a stable installation foundation and positioning reference for the detection piece 321.

[0095] The inspection unit 321 is mounted on a separate second support platform 323, and the second support platform 323 is detachably connected to the punching station 200, thus realizing a modular design for the inspection unit 320. This structure facilitates the individual maintenance, replacement, or calibration of the inspection unit 321 without disassembling the entire punching station 200, thereby significantly reducing maintenance costs and equipment downtime, and improving the flexibility and changeover efficiency of the production line.

[0096] To achieve an insulated connection between the second conductive block 322 and the second support platform 323, the second conductive block 322 includes an angled structure formed by bending a conductive material, comprising a conductive portion 322a and a second connecting portion 322b.

[0097] The first end of the conductive part 322a is in active contact with the first conductive block 311, and the second end of the conductive part 322a is electrically connected to the detection element 321.

[0098] The second connecting part 322b is fixed to the second support platform 323, and a second insulating pad 324 is provided between the two.

[0099] The bending structure allows one end of the second conductive block 322 to reliably contact the first conductive block 311 in the socket assembly 310, and the other end to be stably connected to the detection element 321. The middle part is mechanically fixed to the second support platform 323 through the second connecting part 322b, and electrical isolation is achieved by means of the second insulating pad 324.

[0100] This design not only creates a low-impedance, continuous electrical conduction path, but also effectively prevents short circuits between the conductive part 322a and the metal support structure (such as the second support platform 323). Simultaneously, the bending structure itself has a certain degree of elasticity, which can compensate for positional tolerances during assembly, improving the contact stability and repeatability with the first conductive block 311.

[0101] The second insulating pad 324 uses the same high-insulation engineering material (such as PBT, PEEK or bakelite) as the first insulating pad 317, and has oil resistance, pressure resistance and vibration resistance properties, which will not be described in detail here.

[0102] In order to facilitate the adjustment of the installation position of the detection unit 320 on the punching station 200, in this solution, the second support platform 323 is provided with a waist-shaped hole 323a, and the bolt passes through the waist-shaped hole 323a and is connected to the punching station 200, thereby realizing the position adjustment of the detection unit 320.

[0103] By setting a waist-shaped hole 323a on the second support platform 323, the installation position of the detection unit 320 on the punching station 200 can be flexibly adjusted within a certain range.

[0104] This design significantly enhances the adaptability of the inspection piece 321 to different product models or punching positions: there is no need to re-machine the mounting hole 314a; adjustment can be completed simply by loosening the bolt, moving it to the required position, and then tightening it again. This not only simplifies changeover operations but also greatly shortens debugging time, effectively improving production efficiency and production line flexibility.

[0105] This solution also proposes a punching die, which includes the aforementioned electronic inspection mechanism 300.

[0106] The disassembly and assembly process of the electronic testing mechanism 300 is as follows: When the punching station 200 is installed on the support base 100, the testing unit 320 on it moves accordingly, so that the second conductive block 322 contacts and pushes the first conductive block 311 elastically supported in the socket assembly 310, overcomes the resistance of the elastic element 312 and enters the pressure state. The two are tightly abutted to achieve electrical connection, thereby automatically energizing the testing component 321.

[0107] When the punching station 200 is disassembled, the second conductive block 322 separates from the first conductive block 311, the elastic element 312 drives the first conductive block 311 to reset to its natural state, the power supply is automatically disconnected, and the detection unit 320 is detached from the punching station 200 as a whole, completing a safe and reliable "plug and play" electrical connection and disconnection process.

[0108] In summary, this solution provides a compact, safe, reliable, and easy-to-maintain electronic inspection mechanism 300 for punching dies, which is particularly suitable for stamping applications with high precision and error-proofing requirements, such as the outer water cutting of automotive door frames.

[0109] By setting a socket assembly 310 and a detection unit 320 between the support base 100 and the detachable punching station 200 respectively, and using an elastic floating conductive block to achieve contact-type automatic power on and off, it not only effectively solves the problems of traditional fixed wiring being difficult to debug in a narrow punching space, and cables being easily worn or loose, but also significantly improves the efficiency of mold replacement and backrest assembly adjustment.

[0110] Meanwhile, modular design, adjustable detection positions, and multiple insulation protection measures further enhance the system's adaptability, operational stability, and electrical safety. This technical solution truly achieves intelligent electrical connections that are "ready to use immediately and disconnectable immediately," significantly reducing debugging costs, shortening changeover time, and ensuring production cycle time. It has outstanding practical value and broad prospects for widespread application.

[0111] It should be noted that in this invention, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
