[0002] Police shields are essential protective equipment for law enforcement agencies, and the quality of their stamping process directly affects the structural strength and safety of the equipment. In the manufacturing process of police equipment, the stamping process plays a crucial role in efficiently processing metal sheets into ergonomically curved surfaces, ensuring the product possesses sufficient impact resistance and lightweight characteristics. Due to the complex curved structure of the shield and the high dimensional accuracy requirements, the stamping equipment must have precise mold positioning capabilities and stable forming quality.

[0003] Traditional shield stamping equipment generally suffers from low leveling efficiency and limited positioning accuracy.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0022] As attached Figures 1 to 9 The device shown is a stamping and forming device for a handheld police shield. The frame 1 adopts a frame-type welded structure with reinforcing ribs inside. The surface of the frame 1 is rust-proofed. The support component 101 includes four legs 1011, which are symmetrically distributed and directly connected to the bottom of the frame 1 by bolts. The legs 1011 have reinforcing ribs inside. The leveling screw 1012 adopts a trapezoidal thread structure and has a rotating handle at the bottom.

The punch 202 adopts a modular design, and the working surface of the punch 202 is polished. The connector 203 adopts a quick-change chuck structure. The connector 203 has a positioning pin inside. When the servo electric cylinder receives a control command, the electric push rod drives the connector 203 to move linearly. The connector 203 precisely drives the punch 202 to complete the stamping action through the positioning pin. The leveling base plate 301 of the mold leveling mechanism 3 is made of high-strength alloy steel. The plate, the leveling base plate 301 has a mounting boss on the back, the adjustment unit 302 includes three linear actuators 303, the linear actuators 303 are distributed in a 120-degree circumferential direction, the linear actuators 303 are servo electric push rods, the hinge structure 304 adopts a ball joint connection, the position detector 305 adopts an absolute encoder.

[0025] The tilt detector 9 uses a dual-axis tilt sensor, and the pressure detector 10 uses a thin-film pressure sensor array. When the equipment is working, the tilt detector 9 monitors the tilt angle of the frame 1 in real time, and the pressure detector 10 detects the force distribution of the mold. The data is transmitted to the control unit 6 in real time to form a closed-loop control. Example 2

[0026] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 9 As shown below, see details: Furthermore, the linear actuator 303 is equipped with ball joint structures at both ends, which are connected to the frame 1 and the leveling base plate 301 respectively. The ball joint structure includes a ball socket and a ball head assembly, enabling the linear actuator 303 to adaptively adjust the angle during extension and retraction. The position detector 305 adopts an absolute encoder, which is directly connected to the lead screw of the linear actuator 303 through a coupling. It detects the rotation angle of the lead screw in real time and converts it into a linear displacement signal. The housing of the linear actuator 303 is equipped with heat dissipation fins, and the surface of the movable rod is treated with chrome plating and equipped with a dustproof scraper. When the control unit 6 issues an adjustment command, the motor of the linear actuator 303 drives the lead screw to rotate, pushing the movable rod to make linear motion. The ball joint structure drives the leveling base plate 301 to adjust its position and posture. At the same time, the absolute encoder monitors the lead screw rotation angle in real time and feeds back the position signal to the control unit 6 to form a closed-loop control to ensure leveling accuracy. The ball head of the ball joint structure is equipped with a grease nipple and a sealing ring to ensure flexible rotation and dust and water resistance. The mounting base of the linear actuator 303 is equipped with shock-absorbing pads to reduce vibration transmission during movement.

[0027] Furthermore, the hinge structure 304 adopts a ball joint connection. The ball joint is connected to the end of the linear actuator 303 and the frame 1 or leveling base plate 301 respectively. The ball joint assembly includes a ball seat and a ball head part, enabling the linear actuator 303 to achieve multi-angle adaptive adjustment during extension and retraction. The ball head of the ball joint assembly is provided with a lubrication oil injection hole and a rotary sealing ring. The end of the linear actuator 303 is provided with a mounting flange, which is connected to the ball joint assembly by high-strength bolts. The outer shell of the ball joint assembly is made of wear-resistant alloy steel, and the inner spherical surface is made of copper-based self-lubricating material.

The ball head stroke of the ball joint assembly is provided with a limiting structure to limit the deflection angle within a safe range. The connection between the ball joint assembly and the linear actuator 303 is also provided with a shock-absorbing pad to reduce vibration transmission during movement and ensure the stability and reliability of the hinge structure 304 during operation.

[0028] Furthermore, the spherical plain bearing 309 is made of stainless steel. The outer ring of the spherical plain bearing 309 is connected to the second connecting member 307 with an interference fit, and the inner ring of the spherical plain bearing 309 is connected to the first connecting member 306 with a clearance fit. The locking washer assembly 310 includes multiple alternately stacked flat washers and spring washers. The disc springs 311 are installed in a multi-piece mating combination. When the linear actuator 303 performs telescopic movement, the inner ring of the spherical plain bearing 309 can swing angularly relative to the outer ring, providing multi-degree-of-freedom compensation. The disc spring assembly 311 is pre-compressed. When operating under these conditions, the bearing undergoes elastic deformation to absorb vibration energy under impact loads. The locking washer assembly 310 maintains the fixed position of the constraint member 308 through preload, preventing loosening under vibration. The inner bore of the spherical bearing 309 is equipped with an oil reservoir filled with high-temperature resistant grease to ensure smooth rotation performance under heavy load conditions. The disc spring 311 assembly has hardened washers at both ends to prevent stress concentration from damaging the contact surface. The outermost nut in the locking washer assembly 310 adopts a self-locking nut structure to ensure reliable anti-loosening during long-term use.

[0029] Furthermore, the illuminator 502 adopts a ring-shaped LED light group structure, with the ring-shaped LED light group evenly distributed around the lens of the image acquisition unit 501. The ring-shaped LED light group is equipped with a dimmable controller, and a diffuser is provided on the outside of the ring-shaped LED light group. The diffuser is made of frosted polycarbonate material, and the positioning mark 503 is made of a highly reflective material. The positioning mark 503 is located at the edge of the upper surface of the leveling substrate 301, and the pattern of the positioning mark 503 consists of concentric circles and cross lines. The positioning mark 503 is surrounded by an anti-corrosion coating. When the image acquisition unit 501 is working, the ring-shaped LED light group provides uniform shadowless illumination, and the light passes through the diffuser. After being softened, the light is shone onto the surface of the positioning mark 503. The high reflectivity of the positioning mark 503 reflects the light back to the image acquisition unit 501. The image acquisition unit 501 captures a clear image of the positioning mark 503 and transmits it to the control unit 6. The control unit 6 calculates the precise position and orientation of the stamping die 4 by recognizing the pattern features of the positioning mark 503. The ring LED light group automatically adjusts its brightness according to the ambient light intensity to ensure the best image acquisition effect under different working conditions. The concentric circle pattern of the positioning mark 503 is used for position positioning, and the crosshair pattern is used for angle positioning, together realizing the six-degree-of-freedom pose recognition of the stamping die 4.

[0030] Furthermore, the clamp 701 consists of symmetrically arranged clamping arms. The power source 702 employs a cylinder structure or a drive motor, fixed to the side of the frame 1 via a mounting bracket. The transmission assembly 703 includes a linkage mechanism, with one end connected to the cylinder structure or drive motor and the other end connected to the clamping arms. When the power source 702 operates, it pushes the linkage mechanism to perform linear motion, thereby causing the clamp 701 to perform linear motion. A drive shaft is provided between the linkage mechanism and the clamp 701. The power source 702 can control the drive shaft to rotate via the linkage mechanism. The rotated drive shaft drives the clamp 701 to rotate synchronously, thus realizing the opening and closing action of the clamping arms. When the power source 702 drives the clamp 701 to move up and down via the linkage mechanism, the drive shaft drives the clamp 701 to rotate, thereby driving the clamping surface of the clamp 701 to be parallel to the upper surface of the mold for clamping the mold. The working surface of the clamping arms is provided with anti-slip texture and adopts a replaceable design for easy disassembly and subsequent maintenance.

[0031] Furthermore, the driver 201 adopts a servo motor drive method. The servo motor is mounted on the upper part of the frame 1 via a flange. The output shaft of the servo motor is connected to the ball screw mechanism via a coupling. The nut seat of the ball screw mechanism is rigidly connected to the connector 203. The connector 203 adopts a quick-change structure design. The lower part of the connector 203 is provided with a standardized punch 202 mounting interface. The punch 202 is made of high-strength alloy steel. The working surface of the punch 202 is quenched and polished. The side of the punch 202 is provided with a tool setting reference surface. When the servo motor works, it drives the ball screw mechanism. The mechanism converts rotary motion into linear motion, which drives the punch 202 to make precise up-and-down reciprocating motion through connector 203. Connector 203 is equipped with pressure and displacement sensors to monitor pressure and position data in real time during the stamping process. Linear guide pairs are provided on both sides of the ball screw mechanism to ensure the accuracy of the punch 202's movement trajectory. The connection interface between connector 203 and punch 202 is equipped with positioning pins and anti-rotation keys to ensure the repeatability of the punch 202's installation position. A high-precision encoder is installed at the rear of the servo motor to form a fully closed-loop control system, ensuring the precise controllability of the stamping process.

[0032] Furthermore, the handheld unit 8 adopts an ergonomic design, with its surface covered by an anti-slip rubber layer. The display unit 801 uses a high-brightness LCD touch screen, which is embedded in the front of the handheld unit 8. The operating unit 802 includes an emergency stop button, a mode selection knob, and a group of function buttons. The emergency stop button is located on the upper right side of the handheld unit 8, the mode selection knob is located on the left side of the handheld unit 8, and the group of function buttons is arranged below the LCD touch screen. When the operator holds the handheld unit 8, the thumb can naturally operate the emergency stop button and the mode selection knob, while the index and middle fingers can operate the group of function buttons. The LCD touch screen displays the stamping parameters and equipment status in real time. The operator inputs commands through the touch screen or physical buttons. After receiving the commands, the control unit 6 coordinates the actions of each actuator. The emergency stop button adopts a red mushroom head design and has a self-locking function. The mode selection knob has a clear sense of position. The function buttons adopt a waterproof and oil-proof design to ensure reliable operation in industrial environments. All operating signals are transmitted to the control unit 6 through a waterproof connector.

[0033] Furthermore, the tilt detector 9 adopts a dual-axis digital tilt sensor. The tilt detector 9 is fixed to the top center of the frame 1 by a mounting base.

The pressure detector 10 adopts an array-distributed pressure sensor group. The pressure sensor group is evenly distributed on the working area surface of the leveling base plate 301. The surface of the pressure sensor group is covered with a wear-resistant protective film. The signal line of the pressure sensor group is connected to the control unit 6 through a waterproof connector. When the equipment is working, the tilt detector 9 detects the tilt angle of the frame 1 relative to the horizontal plane in real time. The pressure detector 10 monitors the pressure distribution status of the stamping die 4 on the leveling base plate 301. The control unit 6 simultaneously receives tilt angle data and pressure data, processes them through an algorithm to generate a leveling command, and drives the adjustment unit 302 to perform adaptive leveling. The tilt detector 9 has a built-in temperature compensation circuit to ensure measurement accuracy under different ambient temperatures. The pressure sensor group adopts a bridge measurement circuit, which can detect the uniformity of pressure distribution in real time. When an abnormal pressure is detected, the control unit 6 automatically adjusts the leveling parameters to ensure that the die is subjected to uniform force during the stamping process.

The lower surface of the anti-slip pad 1013 has a cross-grid anti-slip pattern. When performing a leveling operation, the leveling screw 1012 is rotated to adjust the support leg. 012 drives the support leg 1011 to make vertical height adjustment. The trapezoidal thread of the leveling screw 1012 provides a self-locking function to prevent accidental loosening. The reinforcing ribs inside the support leg 1011 improve structural rigidity. The elastic deformation of the anti-slip pad 1013 compensates for unevenness of the ground while providing sufficient friction. Multiple support legs 1011 achieve precise leveling of the frame 1 through coordinated adjustment. The top of the leveling screw 1012 is equipped with a hexagonal operating head for easy adjustment with tools. The side of the support leg 1011 is also equipped with a level indicator for intuitive display of the leveling status.
