It is not suitable for frequent use in ordinary teaching scenarios, and students lack sufficient practical operation opportunities. To solve this problem, a large number of auxiliary devices for stamping teaching or training have appeared on the market.

[0003] After searching by the inventor, the following public schemes for auxiliary teaching aids for stamping teaching are found:

[0004] 1) Publication No. CN111785121A discloses a 1+X stamping module training and teaching device for industrial robots. In this patent application, it includes a base, a support frame, an eight-position waterproof junction box, an electromagnetic air valve, a stamping mechanism, and a clamping and discharging mechanism. A support frame is provided above the base, the clamping and discharging mechanism is provided on the base, the stamping mechanism is installed on the top of the support frame, an eight-position waterproof junction box is installed at the bottom end of the top surface of the support frame, a handle is provided at the side end of the top surface of the support frame, and an electromagnetic air valve is provided at the rear end of the top surface of the support frame.

The present invention has the characteristics of reasonable layout and simple structure, and can be promoted and applied to the automated training and teaching of industrial robot.

[0005] 2) Publication No. CN109326197A discloses a micro desktop stamping teaching device. In this patent application, the device comprises a base, movable wheels are provided below the base, a working panel is provided above the base, a micro punch is provided on one side of the working panel, a micro drawing machine is provided on the other side of the working panel, and a display for displaying the working status of the micro punch and micro drawing machine is provided on the working panel. The present invention facilitates the movement and transportation of the entire micro desktop stamping teaching device by providing movable wheels; and by providing a micro punch and micro drawing machine, it solves the problem that the workbench structure has a single function and cannot fully meet the personalized needs of stamping course experiments, thereby realizing a variety of teaching demonstration processes for the micro desktop stamping teaching device.

[0006] 3) Publication No. CN113751564A discloses a visual teaching demonstration device for stamping. In this patent application, a die base for fixing the die is fixedly connected to the middle of the top surface of the lower die base, a guide column is fixedly connected to the top surface of the lower die base, a support plate is fixedly connected to the top of the guide column, an upper die base is provided between the support plate and the die base, a threaded support sleeve is fixedly provided in the middle of the support plate, the threaded support sleeve passes through the support plate up and down, a matching screw is passed through the threaded support sleeve, the bottom of the screw extends downward into the top surface of the upper die base and is rotatably connected, a torque wrench is also fixedly connected to the top of the screw, a punch is provided at the bottom of the upper die base, a stripper plate is fixedly connected to the top of the die base, a through hole matching the punch is passed through the stripper plate, and the punch, die, die base and the die tightening block that fixes the die to the die base are all transparent. From the above structure, it can be seen that the visual teaching demonstration device for stamping of the present invention realizes the influence of different stamping forces and different sized matching molds on the stamping workpiece.

[0007] 4) Publication No. CN111360153A discloses a multi-station stamping device for teaching. In this patent application, it includes a turntable and a mold. The turntable is provided with at least two grooves, and the grooves are evenly distributed on its upper surface around the turntable. The grooves are provided with openings on the upper surface and side of the turntable; a guide structure is provided between the mold and the grooves in the horizontal direction. Due to the adoption of the above technical solution, compared with the existing technology, the present invention can realize the rapid replacement of the mold (integrated), which is convenient to operate and saves time, so that teachers can demonstrate different stamping processes to students as much as possible within the limited teaching time. In addition, when the turntable rotates to the station that needs to be demonstrated, the hammer can synchronously rise to its stamping height, combining the two operations into one, making the operation more convenient. On the other hand, by setting a reset mechanism, the bracket position can be quickly reset (dropped to the lowest point) to start the next stamping operation.

[0008] However, the above-mentioned prior art has the following technical defects when applied:

[0009] Single-function limitations: Some existing devices have relatively simple functions. For example, the miniature desktop stamping teaching device with publication number CN109326197A, while equipped with a miniature punch press and a miniature drawing machine, can only perform simple stamping and drawing demonstrations. It lacks real-time monitoring and analysis of multiple parameters during the stamping process, making it difficult for students to fully and deeply understand the principles and influencing factors of the stamping process. For example, most devices can only collect a limited number of stamping parameters, such as punching force and punching stroke. They lack effective means to collect other important parameters of the stamping process, such as vibration, strain, and friction. This makes it impossible to provide students with comprehensive data support, which is not conducive to their comprehensive understanding of the stamping process.

[0010] Inadequate safety measures: Some devices lack comprehensive safety considerations. Real stamping equipment is inherently dangerous, and while some teaching aids are smaller in size, they can still pose safety risks such as material splashing and equipment malfunctions during operation. The lack of effective safety measures, such as protective shields, poses a threat to students' personal safety.

[0011] Limited material selection: Most existing devices can only be used with specific types or specifications of materials, making them unable to meet the diverse material requirements of stamping experiments. For example, some devices' molds and stamping parameters are designed for specific materials. When materials of different materials or thicknesses are used, they may not function properly or achieve the desired teaching results. Summary of the Invention

[0012] The purpose of the present invention is to provide a mechanical auxiliary teaching aid for simulating stamping processing. Through the clever combination of simulated feeding mechanism and stamping mechanism, a highly simulated stamping process simulation is achieved, which greatly improves the authenticity and effectiveness of teaching.

[0013] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a mechanical auxiliary teaching aid for simulating stamping processing, comprising a frame, a simulated feeding mechanism and a stamping mechanism, wherein: the frame is a platform structure with an opening on the front side and visual windows on the four sides of the outside, rollers are arranged at the four corners of the bottom side of the frame, a step plate is arranged on the inside of the frame, a warning light is installed on the top side of the frame, and a visual control host is installed on the side of the opening on the front side of the frame; the simulated feeding mechanism and the stamping mechanism are arranged along the height direction of the step plate on the inside of the frame according to the conveying processing direction, the simulated feeding mechanism is provided with at least two groups, the simulated feeding mechanism includes a material library and a feeding manipulator, and the material library has a bulk A heat dissipation base box, a first motor, a guide rod bracket, a push plate, a gasket material, a side guide rail and a first lead screw, wherein the heat dissipation base box is fixed to the step plate by screws, the first motor is installed in the heat dissipation base box, and three guide rod brackets are installed on the heat dissipation base box, the guide rod brackets are L-shaped guide rods and are distributed in a ring shape on the heat dissipation base box; the stamping mechanism includes a pedestal, a stamping electric cylinder, an upper template, a lower template, a damping guide column and a multi-parameter sensor acquisition module, the stamping electric cylinder is installed on the top side of the pedestal, and the shaft end of the stamping electric cylinder is connected to the upper template; the upper template is mounted on the damping guide column and cooperates with the lower template, and the upper template moves with the stamping electric cylinder and approaches and moves away from the lower template.

[0014] Preferably, the push plate is mounted on the three guide rod brackets through a waist-shaped hole, a number of gasket materials are stacked on the push plate, and a connecting frame is provided on the lower side of the push plate; the side guide rail is fixed to one side of the end face of the heat dissipation base box, and a vertical first lead screw is provided on the inner side of the side guide rail, and the upper and lower ends of the first lead screw are respectively connected to the upper end of the side guide rail and the first motor shaft end.

[0015] Preferably, a movable seat is slidably mounted on the side guide rails. The movable seat is mounted on the first lead screw and its side end is fixedly connected to the connecting frame. When the first lead screw rotates, the push plate moves along the side guide rails and ejects the gasket material upward. The push plate can carry a certain amount of gasket material and eject the material layer by layer through stable movement, providing a continuous material supply to the simulated feeding mechanism, ensuring the continuity of the stamping process during teaching or practice, improving teaching efficiency and the smoothness of practical operation.

[0016] Preferably, the feeding robot is used to absorb and transfer the gasket material in the material warehouse. The feeding robot includes a horizontal guide rail, a horizontal slide, a first electric cylinder, a vertical guide rail, a vertical slide, a second motor, a second screw, a horizontal arm, a first suction cup unit, a second suction cup unit, a transfer table and an electric splint. The back side of the horizontal guide rail is fixed to the heat dissipation base box through a bracket, and the second screw is rotatably installed on the inner side of the horizontal guide rail. The second screw is driven by the second motor, and the front side of the horizontal guide rail is slidably connected to the horizontal slide.

[0017] Preferably, a vertical guide rail is provided on the front side of the transverse slide, an electric cylinder is provided on the transverse slide, the vertical slide is slidably connected to the vertical guide rail and its end is connected to the shaft end of the first electric cylinder; a horizontal arm is installed at the bottom end of the vertical slide, and the left and right side ends of the horizontal arm are respectively installed with the first suction cup unit and the second suction cup unit.

[0018] Preferably, the first suction cup unit and the second suction cup unit are electrically controlled suction cups based on magnetic adsorption or negative pressure adsorption.

[0019] When handling metal gaskets, the magnetically-attached first or second suction cup units offer significant advantages. Magnetic attraction provides stable holding power, ensuring the metal material remains in place despite vibration or shaking during material handling by the feeding robot.

[0020] For non-metallic gasket materials like plastics and composites, the negative pressure suction cups are ideal for the first or second suction cups. By generating negative pressure, the cups adhere tightly to the surface, creating a good seal and effectively adsorbing the non-metallic material.

[0021] Preferably, the transfer table is installed on one side of the material warehouse and close to the stamping mechanism through a bracket, and an electric clamping plate is provided on the transfer table.

[0022] Preferably, the multi-parameter sensor acquisition module includes a pressure sensor, a displacement sensor, and a strain sensor. The multi-parameter sensor acquisition module also includes a vibration sensor, a friction sensor, and an acceleration sensor.

[0023] Pressure sensors, located at the end of the electric cylinder shaft, accurately and in real time collect pressure data during the stamping process. This data directly reflects changes in the stamping force and is crucial for studying the pressure required to stamp materials of varying thicknesses.

[0024] Displacement sensor: Installed on the damping guide column, it accurately measures the displacement of the upper platen during the stamping process. It provides real-time feedback on the upper platen's movement distance and speed, helping students understand the impact of stamping stroke and speed on material forming results.

[0025] Strain sensors, embedded in the contact surface between the upper and lower mold plates, directly measure material strain during the stamping process. Strain data reflects the degree of material deformation under stress and is crucial for studying material deformation patterns and forming properties. For example, using data collected by strain sensors, students can observe the strain distribution of different materials during stamping, analyze the local and overall deformation characteristics of the materials, and provide a basis for optimizing mold design and stamping processes.

[0026] Friction sensor: Placed between the upper and lower mold plates, it measures the friction between the two mold plates in real time during the stamping process. By collecting friction data, students can study the effects of different lubrication conditions and material combinations on friction, and take appropriate measures to reduce friction, improve stamping quality, and improve die life.

[0027] Vibration sensors, installed on the pedestal, monitor vibrations during the stamping process in real time. Vibration data can reflect the operational stability of the equipment and the dynamic characteristics of the mechanical structure. Excessive vibration can lead to problems such as reduced part quality and mold damage.

[0028] Accelerometer: Integrated into the upper platen, it measures changes in its acceleration during the stamping process. Accelerometer data reflects the dynamic response of the upper platen and is crucial for studying impact and vibration during the stamping process. For example, by analyzing acceleration data, students can understand the acceleration changes of the upper platen at the moment of contact with the material, assess the impact force during the stamping process, and provide a reference for optimizing stamping processes and equipment design.

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

[0030] 1. The present invention realizes a highly simulated stamping process simulation through the ingenious combination of the simulated feeding mechanism and the stamping mechanism. The simulated feeding mechanism accurately and orderly transports the material to the stamping position, and the stamping mechanism accurately completes the stamping action according to the preset parameters. The two work closely together to completely restore the feeding and stamping collaborative process in actual production. In this highly simulated environment, students can personally experience the entire process from material supply to product molding, and become familiar with the operating points and interrelationships of each link, which greatly improves the authenticity and effectiveness of teaching.

[0031] 2. The present invention expands the depth and breadth of teaching through the combination of different materials and materials of different thicknesses in the material library. The simulated material sheets of different materials (such as metals, plastics, and composite materials) allow students to intuitively compare the deformation laws and forming effects of various materials during the stamping process, broadening their understanding of stamping material selection. The provision of materials of different thicknesses enables students to conduct in-depth research on the impact of material thickness on stamping process parameters (such as punching pressure, die gap, etc.), as well as problems that may arise during stamping of materials of different thicknesses (such as wrinkling, cracking, etc.). This diversified material design meets the teaching needs of students of different majors and levels, and cultivates students' practical ability and innovative thinking.

[0032] 3. The frame provided by the present invention is a platform structure with an opening on the front and visual windows on all four sides. Students can observe the stamping process from multiple angles, clearly see the deformation of the material, the movement of the mold, and the working status of each component, which enhances the intuitiveness of teaching. In addition, through the combination of the multi-parameter sensor acquisition module and the visual control host, the real-time acquisition and intuitive presentation of the stamping process data are realized. The multi-parameter sensor acquisition module can accurately obtain multi-dimensional data such as stamping force, displacement, strain, vibration, friction, acceleration, etc., and these data are clearly displayed in the form of charts, curves, etc. through the visual control host. Students can observe data changes in real time, deeply understand the dynamic characteristics of the stamping process, closely combine abstract theoretical knowledge with specific operating procedures, and deepen their understanding of the impact of stamping principles and process parameters.

[0055] Example 2 discloses a mechanical auxiliary teaching aid for simulating stamping processing. It achieves multiple goals such as enriching teaching content, improving teaching effects and cultivating students' comprehensive abilities by combining different materials and materials of different thicknesses in the material library 2 and combining multiple sets of simulated feeding mechanisms and the precise operation of the feeding robot 3.

[0056] The material library 2 of Example 2 is equipped with simulated material sheets of different materials such as metal, plastic, and composite materials. During the stamping teaching process, students can intuitively observe the deformation laws of different materials during the stamping process. For example, metal materials usually have higher strength and toughness, and deform relatively uniformly during stamping, but may rebound; while plastic materials have better ductility and are prone to large plastic deformation during stamping, but may cause problems such as tearing. By comparing the molding effects of different materials, students can deeply understand the characteristics of various materials and broaden their understanding of the selection of stamping materials. In addition, material library 2 also provides materials of different thicknesses. Students can change the thickness of the material and conduct in-depth research on its impact on stamping process parameters (such as stamping pressure, die gap, etc.). For example, as the thickness of the material increases, the required stamping pressure will also increase accordingly; at the same time, in order to ensure the quality of stamping, the die gap also needs to be appropriately adjusted. In addition, students can also observe the problems that may arise in stamping of materials of different thicknesses, such as thin materials are prone to wrinkling, while thick materials are more likely to break.

[0057] For example, when conducting a metal and plastic stamping experiment, students can clearly see that metal stamping parts have smooth surfaces and high dimensional accuracy, but may require greater stamping pressure; whereas plastic stamping parts may have some burrs but require relatively less pressure. This intuitive comparison helps students understand the application scenarios of different materials in stamping.

[0058] Example 2, through this diverse material design and precise feeding mechanism, can meet the teaching needs of students from different majors and levels. For junior students, simple stamping experiments can help them understand the basic stamping characteristics of materials of different materials and thicknesses. For senior students, more in-depth research projects can be carried out, such as optimizing stamping process parameters and solving problems that arise during the stamping process.

[0059] In combination with the above-mentioned embodiment 1 and embodiment 2, the present invention further provides steps for using the above-mentioned auxiliary teaching aid, including:

[0060] 1) Place the teaching aids in a stable and spacious teaching or practice area, and ensure that the bottom rollers of the rack 1 are locked to prevent the teaching aids from moving during teaching.

[0061] 2) According to teaching needs, prepare simulated material sheets of different materials such as metal, plastic, and composite materials, as well as materials of the same material of different thicknesses, and stack the prepared materials on the push plate 204 of the material library 2. According to the structure of the material library 2 in Example 2, the push plate 204 is mounted on the three guide rod brackets 203 through the waist-shaped holes, and ensure that the connecting frame on the lower side of the push plate 204 is fixedly connected to the movable seat on the side guide rail 206.

[0062] 3) Open the visual control host 103 and initialize the device according to the prompts on the operation interface. During the initialization process, check whether each sensor is working properly and whether the motors of the stamping cylinder 402 and the feeding robot 3 are in standby mode.

[0063] 4) Select the teaching demonstration mode on the visual control host 103. In the teaching demonstration mode, the visual control host 103 controls the first motor 202 in the material library 2 to start, and the first motor 202 drives the first screw 201 to rotate. The movable seat moves along the side guide rail 206, pushing the push plate 204 to eject the gasket material 205 upward. When the material is ejected to the appropriate position, the feeding robot 3 starts to work, that is, the second motor 306 drives the second screw 307 to rotate, driving the transverse slide 302 to move forward on the transverse guide rail 301. At the same time, the first electric cylinder 303 drives the vertical slide 305 to move on the vertical guide rail 304, so that the second suction cup unit 310 on the cross arm 308 reaches above the material, and the first suction cup unit 309 extends to the inner position of the stamping mechanism 4 (no load); the second suction cup unit 310 reaches above the material, and the first suction cup unit 309 extends to the inner position of the stamping mechanism 4 (no load); The disc unit 310 absorbs and grabs the material and transfers it to the transfer table 311, and the electric clamping plate 312 on the transfer table 311 performs preliminary positioning of the material; then the transverse slide 302 is controlled to move backward, so that the first suction cup unit 309 is directly above the transfer table 311, and the second suction cup unit 310 is directly above the material library 2, and the first suction cup unit 309 and the second suction cup unit 310 respectively move downward with the vertical slide 305 to pick up the material; after the material is picked up, the transverse slide 302 is controlled to move forward. At this time, the first suction cup unit 309 extends to the inner position of the stamping mechanism 4, and the second suction cup unit 310 is directly above the transfer table 311. The first suction cup unit 309 and the second suction cup unit 310 are controlled to move downward and release the material. By repeating this step, cyclic feeding is achieved.

[0064] 5) The stamping cylinder 402 starts, driving the upper template 404 to move downward along the damping guide post 403, approaching the lower template 405. The upper template 404 and the lower template 405 cooperate to stamp the material. During the stamping process, the multi-parameter sensor acquisition module begins to operate. The pressure sensor collects pressure data from the shaft end of the stamping cylinder 402, the displacement sensor collects displacement data from the damping guide post 403, the strain sensor collects strain data from the contact surface between the upper template 404 and the lower template 405, the vibration sensor collects vibration data from the base 401, the friction sensor collects friction data between the upper template 404 and the lower template 405, and the acceleration sensor collects acceleration data from the upper template 404. This data is transmitted in real time to the visual control host 103 for teachers and students to observe and analyze.

[0065] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Any changes, modifications, replacements and variations of the above embodiments by ordinary technicians in this field within the scope of the present invention should be included in the scope of protection of the present invention.
