Description

Technical Field

[0001] This utility model belongs to the field of sheet metal stamping technology, and relates to a quick-change stamping head for a sheet metal stamping forming device. Background Technology

[0002] In sheet metal stamping production, rapid changeover of stamping heads is crucial for improving production efficiency and flexibility. However, existing technologies have several drawbacks in achieving rapid stamping head changeover. Traditional stamping head changeover processes are typically time-consuming and require specialized technicians, leading to excessively long die-changing times on the production line and reducing overall production efficiency. The complexity of the changeover process increases equipment wear and failure rates, consequently affecting production stability and product quality. These drawbacks stem from limitations in the design and manufacturing technology of traditional stamping equipment, as well as insufficient automation and standardization of the stamping head changeover process. To address these shortcomings, conventional methods include adopting modularly designed stamping heads and introducing automated changeover systems. Modular design simplifies the changeover process, while automated systems reduce manual operation and increase changeover speed. However, these methods also have drawbacks. While modular design simplifies the changeover process, it may increase the initial investment cost of the equipment and places higher demands on the compatibility and versatility of the stamping heads. Automated changeover systems, while improving efficiency, also require significant capital investment and demand higher technical skills from maintenance and operation personnel. Furthermore, automated systems may lack flexibility when faced with non-standard or special-specification stamping heads, making it difficult to adapt to rapidly changing market demands. Therefore, there is an urgent need for a quick-change stamping head for sheet metal stamping forming devices to solve the above problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a quick-change stamping head for a sheet metal stamping forming device, so as to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a quick-change stamping head for a sheet metal stamping forming device, comprising: a stamping electric cylinder and a support base, wherein the lower end of the stamping electric cylinder is provided with a set of cylinder heads for releasing the stamping pressure, and the lower ends of the left and right sides of the stamping electric cylinder are respectively provided with a set of support frames for supporting their lower ends, and the inner side of the lower ends of the two sets of support frames is provided with a set of head-changing components for quick replacement of the stamping head;

[0005] The head-changing component includes a motor and a stamping head. The head-changing component is embedded inside two sets of support frames. A protective shell is provided on the outside of the motor to protect several sets of stamping heads. The protective shell is fixed to the outside of the motor by bolts. The motor is located behind the connecting column. A set of rotating seats is provided at the lower end of the motor to drive the rotating disk to rotate. A set of rotating disks is provided on the outside of the rotating seats to drive several sets of stamping heads to rotate. The rotating disks have a semi-circular structure. Several sets of clamping seats are distributed on the outside of the rotating disks to hold the stamping heads.

[0006] In a preferred embodiment, several sets of clamps and rotating seats are fixedly connected by bolts. Each set of clamps has an inner groove for placing and quickly replacing stamping heads, and each inner groove contains a set of stamping heads to be replaced. In actual use, the operator first confirms that the equipment is powered off and checks whether the fixing bolts of the support frame and the stamping cylinder are tight. Before starting, the rotating disc needs to be manually rotated to ensure that the spare stamping head in the inner groove of the clamp is installed in place and is not loose. During formal operation, the motor drives the rotating seat through the control panel, so that the current working stamping head on the outer side of the semi-circular structure of the rotating disc is precisely aligned with the center position of the stamping cavity. When it is necessary to replace the stamping head, the system pauses the operation of the stamping cylinder, and the motor automatically drives the rotating disc to rotate 180 degrees, switching the preset spare stamping head to the working position. The clamp achieves quick positioning and locking through the mechanical limit of the inner groove. After the replacement is completed, the side pressure seat and the guide seat work together to ensure the stability of the stamping pressure transmission, and the cylinder head releases uniform pressure with the cooperation of the lower connecting column, thereby quickly completing the replacement of the stamping head.

[0007] In a preferred embodiment, the lower end of the cylinder head is provided with a set of lower connecting columns for transmitting the impact force, and a set of side limiting pressure seats are provided on the left and right sides of the lower connecting columns for cooperating with the lower connecting columns to lift in the opposite direction.

[0008] In a preferred embodiment, the side limiting pressure seat includes a spring, a connecting frame, and an air damping column. The front cross-section of the connecting frame is a Y-shaped structure. The two sets of the connecting frames are located on the outer sides of the left and right ends of the lower connecting column, and are mutually engaged and abutted by a set of springs and air damping columns.

[0009] In a preferred embodiment, the two sets of connecting frames are bolted to the support frame on the outside. The lower end of the lower connecting column is provided with a set of support plates for supporting the lower end of the spring and the air damping column. The lower end of the support plate is provided with a set of guide seats for guiding the replacement stamping head.

[0010] In a preferred embodiment, the guide seat has a hollow structure inside, and the center of the top-view cross-section inside the guide seat is on the same axis as the center of the top-view cross-section of the lower connecting column. The lower connecting column and the cylinder head are an integral structure, and both are movable structures.

[0011] In a preferred embodiment, the rotary table is located in the middle between the support plate and the guide seat. The lower end of the guide seat is provided with a set of stamping chambers for stamping the workpiece, and the lower ends of the two sets of support frames are provided with a set of support seats for supporting them. After the equipment is started, the stamping electric cylinder drives the cylinder head to press down, and the pressure is transmitted to the support plate through the integrated lower connecting column. At this time, the springs of the Y-shaped frames on both sides are compressed synchronously, and the air damping column provides dynamic buffering, forming a reverse balance of the stamping pressure. When the stamping head contacts the workpiece, the guide seat ensures that the stamping head accurately enters the stamping chamber in the vertical direction. When changing the stamping head, the rotary table rotates and switches between the support plate and the guide seat. The hollow structure of the guide seat provides vertical guidance for the stamping head. After stamping is completed, the spring of the side pressure limiting seat resets and pushes the lower connecting column back to its position. The air damping column suppresses the rebound vibration, thereby further improving the stamping head replacement effect.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: by activating the motor drive rotating seat through the control panel, the current working stamping head on the outer side of the semi-circular structure of the rotating disk is precisely aligned with the center position of the stamping cavity. When it is necessary to replace the stamping head, the system pauses the operation of the electric cylinder for stamping, and the motor automatically drives the rotating disk to rotate 180 degrees to switch the preset spare stamping head to the working position. The clamping seat achieves rapid positioning and locking through the mechanical limit of the inner groove. After the replacement is completed, the side pressure limiting seat and the guide seat work together to ensure the stability of the stamping force transmission, and the cylinder head releases uniform pressure with the cooperation of the lower connecting column, thereby quickly completing the replacement of the stamping head.

[0013] When changing the stamping head, the rotary table rotates between the support plate and the guide seat. The hollow structure of the guide seat provides vertical guidance for the stamping head. After stamping is completed, the spring of the side pressure seat pushes the connecting column back to its original position, and the air damping column suppresses the rebound vibration, thereby further improving the stamping head replacement effect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 As the first embodiment of this utility model:

[0023] A quick-change stamping head for a sheet metal stamping forming device includes: a stamping cylinder 100, a head-changing component 160, and a support base 180. The lower end of the stamping cylinder 100 is provided with a set of cylinder heads 120 for releasing the stamping force. The lower ends of the left and right sides of the stamping cylinder 100 are respectively provided with a set of support frames 110 for supporting their lower ends. The inner side of the lower end of the two sets of support frames 110 is provided with a set of head-changing components 160 for quick-change of the stamping head.

[0024] The head-changing component 160 includes a motor 16a and a stamping head 16f. The head-changing component 160 is embedded inside two sets of support frames 110. A set of protective shells 16b is provided on the outside of the motor 16a to protect several sets of stamping heads 16f. The protective shells 16b are fixed to the outside of the motor 16a by bolts. The motor 16a is located on the rear side of the connecting column. A set of rotating seats 16c is provided at the lower end of the motor 16a to drive the rotating disk 16d to rotate. A set of rotating disks 16d is provided on the outside of the rotating seat 16c to drive several sets of stamping heads 16f to rotate. The rotating disks 16d are semi-circular structures. Several sets of clamping seats 16e are distributed on the outside of the rotating disks 16d to clamp the stamping heads 16f.

[0025] Several sets of clamps 16e and rotating seats 16c are fixedly connected by bolts. Each set of clamps 16e has an inner groove for quick replacement of stamping heads 16f, and each inner groove contains a set of stamping heads to be replaced. In actual use, the operator first confirms that the equipment is powered off and checks whether the fixing bolts of the support frame 110 and the stamping cylinder 100 are tight. Before starting, the rotating disc 16d needs to be manually rotated to ensure that the spare stamping head 16f in the inner groove of the clamp 16e is installed in place and is not loose. During formal operation, the motor 16a is activated through the control panel to drive the rotating seat 16c. This ensures that the currently working stamping head 16f on the outer side of the semi-circular structure of the rotary table 16d is precisely aligned with the center position of the stamping cavity 170. When the stamping head needs to be replaced, the system pauses the operation of the stamping cylinder 100, and the motor 16a automatically drives the rotary table 16d to rotate 180 degrees, switching the preset spare stamping head 16f to the working position. The clamp 16e achieves rapid positioning and locking through the mechanical limit of the inner groove. After the replacement is completed, the side pressure limiting seat 140 and the guide seat 150 work together to ensure the stability of the stamping force transmission, and the cylinder head 120 releases uniform pressure with the cooperation of the lower connecting column 130, thereby quickly completing the replacement of the stamping head.

[0026] Please see Figures 1-4 As a second embodiment of the present invention: based on the description in the above embodiments, the lower end of the cylinder head 120 is provided with a set of lower connecting columns 130 for transmitting the impact force, and a set of side pressure limiting seats 140 are provided on the left and right sides of the lower connecting columns 130 for cooperating with the lower connecting columns 130 to lift in the opposite direction.

[0027] The side-limiting pressure seat 140 includes a spring, a connecting frame, and an air damping column. The front cross-section of the connecting frame is a Y-shaped structure. The two sets of connecting frames are located on the left and right sides of the lower connecting column 130, respectively, and are mutually engaged and abutted by a set of springs and air damping columns.

[0028] The two sets of connecting frames are bolted to the support frame 110 on the outside. The lower end of the lower connecting column 130 is provided with a support plate for supporting the lower end of the spring and the air damping column. The lower end of the support plate is provided with a guide seat 150 for guiding the replacement stamping head 16f.

[0029] The guide seat 150 has a hollow structure inside, and the center of the top view cross-section of the guide seat 150 is on the same axis as the center of the top view cross-section of the lower connecting column 130. The lower connecting column 130 and the cylinder head 120 are an integral structure, and both are movable structures.

[0030] The rotary table 16d is located in the middle between the support plate and the guide seat 150. The lower end of the guide seat 150 is provided with a set of stamping chambers 170 for stamping the workpiece. The lower ends of the two sets of support frames 110 are provided with a set of support seats 180 for supporting them. After the equipment is started, the stamping electric cylinder 100 drives the cylinder head 120 to press down, and the pressure is transmitted to the support plate through the integrated lower connecting column 130. At this time, the springs of the Y-shaped frames on both sides are compressed synchronously, and the air damping column provides dynamic buffering, forming a reverse balance of the stamping pressure. When the stamping head contacts the workpiece, the guide seat 150 ensures that the stamping head 16f enters the stamping chamber 170 accurately in the vertical direction. When changing the stamping head, the rotary table 16d rotates and switches between the support plate and the guide seat 150. The hollow structure of the guide seat 150 provides vertical guidance for the stamping head 16f. After the stamping is completed, the spring of the side pressure seat 140 returns to its original position and pushes the lower connecting column 130 back to its original position. The air damping column suppresses the rebound vibration, thereby further improving the stamping head replacement effect.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
