Description

Technical Field

[0001] This utility model relates to the field of head mold technology, and in particular to a head pressing mold with a quick positioning fixture. Background Technology

[0002] End caps are components used to seal the ends of containers and isolate them from the internal and external media. They are also known as end caps and are important components of pressure vessels. The quality of end caps directly affects the safety of pressure vessels.

[0003] For example, patent number CN202162277U discloses a stamping die for forming end caps. The working surface of the punch matches the concave surface of the end cap, and the working surface of the die matches the convex surface of the end cap. During the production process, the punch and die work together to stamp out the required end cap. According to the different shapes required for the end caps, the shapes of the punch and die can be changed to manufacture different types of end caps. In addition, a stripping spring is set in the middle of the die to push out the end cap after stamping, which makes it easy to remove the end cap.

[0004] However, although existing head forming stamping dies can achieve head stamping through the cooperation of punch and die and complete the ejection using the ejection spring, in practical applications, workpiece clamping relies on manual positioning and lacks a fast and accurate adaptive clamping mechanism, resulting in low clamping efficiency and poor repeatability. Especially when changing workpieces of different sizes, the fixtures need to be readjusted or replaced. Moreover, the ejection mechanism has a single function, relying only on the passive ejection of the spring and cannot be linked with the clamping / releasing action, which easily leads to problems such as untimely ejection, jamming, or ejection deviation, affecting the part removal efficiency and product surface quality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a head pressing and forming mold with a quick positioning fixture. This solves the problem that while existing head forming stamping dies can achieve head stamping through the cooperation of a punch and die and use an ejection spring for ejection, in practical applications, workpiece clamping relies on manual positioning and lacks a fast and precise adaptive clamping mechanism. This results in low clamping efficiency and poor repeatability, especially when changing workpieces of different sizes, requiring readjustment or replacement of the fixture. Furthermore, the ejection mechanism has a single function, relying solely on the passive ejection of the spring and unable to be linked with the clamping / releasing action, easily leading to problems such as untimely ejection, jamming, or misalignment, affecting part removal efficiency and product surface quality.

[0006] The technical solution of this utility model is as follows: a head pressing and forming mold with a quick positioning fixture, including a device base, a lower mold fixedly connected to the top of the device base, displacement seats movably connected to both sides of the top surface of the lower mold, a guide plate provided below the displacement seats on the inner wall of the device base, the bottom end of the displacement seats extending to the inner side of the guide plate, an adjustment component provided at the intersection of the two displacement seats at the bottom end of the guide plate, the adjustment component being used to adjust the distance between the two displacement seats, an ejection component provided at the top of the guide plate, the ejection component being used to eject the workpiece; the adjustment component includes a servo motor, the output end of the servo motor being fixedly connected to a transmission gear, the two displacement seats being symmetrical about the transmission gear in opposite directions, the transmission gear... The two ends of the ejector are equipped with racks on the outer side of the displacement seats. The transmission gear meshes with the rack. When the servo motor drives the transmission gear to rotate, the transmission gear, in conjunction with the rack, drives the two displacement seats to move on the outer side of the lower mold. The ejector assembly includes an ejector seat. The two ends of the ejector seat are equipped with guide frames on the top surface of the guide plate. A connecting spring is fixedly connected to the inner wall of the guide frame. The ejector seat is movably connected to the guide frame through the connecting spring. The two ends of the ejector seat are equipped with contact blocks A on the outer side of the guide frame. One end of contact block A is in contact with the displacement seat. When the two displacement seats move outward, the ejector seat moves upward on the inner side of the guide frame. When the two displacement seats move inward, the ejector seat moves downward on the inner side of the guide frame.

[0007] Preferably, a support frame is fixedly connected above the lower mold at the top of the device base, and a stamping assembly is provided on the inner side of the support frame. The stamping assembly includes a cylinder, a rod is fixedly connected to the output end of the cylinder, and an upper mold is fixedly connected to the bottom end of the rod. When the stamping assembly is started, the workpiece can be stamped by the cylinder, the rod and the upper mold.

[0008] Preferably, the upper mold has guide seats at both ends located on the inner wall of the support frame, and the two ends of the upper mold extend to the inner side of the guide seats. When the cylinder drives the upper mold to move, the upper mold moves inside the guide seats.

[0011] Preferably, the inner wall of the displacement seat is provided with a contact block B, one end of which extends to the outside of the contact block A. The intersection of the contact block B and the contact block A is a slope, and one end of the slope is provided with evenly distributed inclined blocks. The contact block B and the contact block A are engaged with the inclined blocks through the slope.

[0012] Preferably, the top of the displacement seat is provided with a connecting seat, and the top surface of the connecting seat is provided with a screw hole. When the workpiece is placed on the top surface of the lower mold, the workpiece can be fixed to the connecting seat by bolts.

[0013] The beneficial effects of this utility model are: This head pressing mold with quick positioning fixture uses a servo motor to drive the transmission gear and rack, enabling the two displacement seats to move inward synchronously and automatically adapt to workpieces of different sizes. With the connecting seat, the workpiece can be quickly and firmly fixed with bolts, significantly improving clamping efficiency and positioning accuracy. The inclined surface and inclined block interlocking structure between contact block A and contact block B automatically trigger the ejection action when the displacement seat moves outward, making it easy to smoothly eject the formed head from the lower mold.

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.

[0017] Please see Figures 1-4 This utility model provides an embodiment: a head pressing mold with a quick positioning fixture, including a device base 1, a lower mold 2 fixedly connected to the top of the device base 1, displacement seats 15 movably connected to both sides of the top surface of the lower mold 2, a guide plate 8 provided below the displacement seats 15 on the inner wall of the device base 1, the bottom end of the displacement seats 15 extending to the inner side of the guide plate 8, an adjustment component provided at the intersection of the two displacement seats 15 at the bottom end of the guide plate 8, the adjustment component being used to adjust the distance between the two displacement seats 15, and a top... The ejection assembly is used to eject the workpiece; the adjustment assembly includes a servo motor 9, which is a self-locking motor (CN213817474U, a self-locking motor with a simple damping mechanism structure, easy assembly, and low manufacturing cost; no noise is generated at the damping mechanism when the motor is running normally, and it is silent when the self-locking function is exerted; the self-locking force of the damping plate on the motor shaft can be adjusted by the holding mechanism bar, thus improving the performance). The output end of the servo motor 9 is fixedly connected to a transmission gear 20, and two displacement seats 15 are... The transmission gear 20 is symmetrical in opposite directions around the center. Racks 19 are located at both ends of the transmission gear 20 on the outer sides of the displacement seats 15. The transmission gear 20 and racks 19 mesh with each other. When the servo motor 9 drives the transmission gear 20 to rotate, the transmission gear 20, in conjunction with the racks 19, drives the two displacement seats 15 to move on the outer side of the lower mold 2. The ejection assembly includes an ejector seat 10. Guide frames 11 are located at both ends of the ejector seat 10 on the top surface of the guide plate 8. Connecting springs 16 are fixedly connected to the inner walls of the guide frames 11. The ejector seat 10 is connected to the guide plate 8 via the connecting springs 16. The frame 11 is a movable connection, and the connecting spring 16 is a compression spring with a calibrated elastic coefficient to ensure that the ejector seat 10 can automatically return to its initial position without external force, thus ensuring the consistency of each pressing cycle. The two ends of the ejector seat 10 are provided with contact blocks A12 on the outside of the guide frame 11. One end of the contact block A12 is in contact with the displacement seat 15. When the two displacement seats 15 move outward, the ejector seat 10 moves upward inside the guide frame 11. When the two displacement seats 15 move inward, the ejector seat 10 moves downward inside the guide frame 11.

[0018] Please see Figures 1-2In this embodiment, a support frame 4 is fixedly connected above the lower mold 2 at the top of the device base 1. A stamping assembly is provided on the inner side of the support frame 4. The stamping assembly includes a cylinder 5. A pneumatic rod 6 is fixedly connected to the output end of the cylinder 5. An upper mold 7 is fixedly connected to the bottom end of the pneumatic rod 6. When the stamping assembly is started, the workpiece can be stamped by the cylinder 5 in conjunction with the pneumatic rod 6 and the upper mold 7. Guide seats are provided at both ends of the upper mold 7 on the inner wall of the support frame 4. The two ends of the upper mold 7 extend to the inner side of the guide seats. When the cylinder 5 moves the upper mold 7, the upper mold 7 is displaced inside the guide seats. A control panel 3 is fixedly connected to one side of the front end face of the device base 1. The control panel 3 is electrically connected to the adjustment assembly and the stamping assembly. When the device is started, the adjustment assembly and the stamping assembly can be controlled by the control panel 3 respectively.

[0019] Please see Figures 3-4 In this embodiment, the inner wall of the lower mold 2 is provided with a through hole 17, and the top of the ejector seat 10 is provided with an ejector rod 14. The ejector rod 14 and the through hole 17 are identical in shape and number, and the ejector rod 14 and the through hole 17 correspond one-to-one. When the ejector seat 10 moves upward, the ejector rod 14 at the top of the ejector seat 10 is inserted into the inner side of the through hole 17. The top of the ejector rod 14 is provided with a buffer rubber pad or polyurethane pad to avoid scratching or deformation of the surface of the molded head during the ejection process. The displacement seat 15... The inner wall is provided with a contact block B13, one end of which extends to the outside of the contact block A12. The intersection of the contact block B13 and the contact block A12 is a slope, and one end of the slope is provided with evenly distributed inclined blocks. The contact block B13 and the contact block A12 are engaged with the inclined blocks through the slope. The top of the displacement seat 15 is provided with a connecting seat 18, and the top surface of the connecting seat 18 is provided with a screw hole. When the workpiece is placed on the top surface of the lower mold 2, the workpiece can be fixed to the connecting seat 18 by bolts.

[0020] During operation, the power is turned on and the device is started. The adjustment component is activated via the control panel 3, and the control system drives the servo motor 9 to rotate the transmission gear 20. Since the transmission gear 20 meshes with the racks 19 on both sides, and the two displacement seats 15 are arranged symmetrically in opposite directions around the gear, the two displacement seats 15 move inward synchronously. The connecting seat 18 at the top of the displacement seat 15 is adapted to the size of the workpiece, making it easy to fix the connecting seat 18 to the workpiece with bolts. Then, the stamping component is activated via the control panel 3. The cylinder 5 in the stamping component, in conjunction with the air rod 6, causes the upper die 7 to stamp the workpiece. After stamping is completed, the cylinder 5 retracts, and the upper die 7 resets. Upon reaching the initial height, the workpiece is then released from the fixing of the connecting seat 18. The control system drives the servo motor 9 to reverse again, causing the transmission gear 20 to drive the two displacement seats 15 to move outward synchronously. As the displacement seat 15 moves outward, the contact block B13 on its inner side pushes the contact block A12 to slide outward and downward (because the two are inclined surface mating inclined block locking structures), thereby releasing the downward pressure on the ejector seat 10. Under the elastic force of the connecting spring 16, the ejector seat 10 moves upward along the guide frame 11, and the ejector rod 14 at the top of the ejector seat 10 rises accordingly, passing through the through hole 17 of the lower mold 2, and smoothly lifting the formed end cap from the surface of the lower mold 2, making it easy for the workers to remove the end cap. Compared to the reference document CN202162277U, the head forming stamping die uses a punch whose working surface matches the concave surface of the head, and a die whose working surface matches the convex surface of the head. During the production process, the punch and die work together to stamp out the required head. Depending on the different shapes of the head required, the shapes of the punch and die can be changed to manufacture different types of heads. In addition, a stripping spring is set in the middle of the die to eject the head after stamping, making it easy to remove the head. This application uses a servo motor to drive a transmission gear and rack to achieve synchronous inward movement of two displacement seats, automatically adapting to workpieces of different sizes. With the help of the connecting seat, the workpiece can be quickly and firmly fixed with bolts, significantly improving clamping efficiency and positioning accuracy. Furthermore, by utilizing the inclined surface and inclined block engagement structure between contact block A and contact block B, the ejection action is automatically triggered when the displacement seat moves outward, making it easy to smoothly eject the forming head from the lower mold.

[0021] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
