Description

Technical Field

[0001] This utility model relates to the field of CNC stamping machine tools, and in particular to a CNC stamping machine tool worktable with a quick mold changing structure. Background Technology

[0002] CNC punching machine is short for numerical control punching machine. It is an automated machine tool equipped with a program control system. It uses a special CNC system to precisely control the operation of the machine tool, so that it can punch sheet metal according to a pre-programmed processing program.

[0003] When CNC stamping machines are in operation, a worktable is needed to support and install stamping dies. However, traditional CNC stamping machine worktables require manual disassembly and installation of dies during die changes, which is complex and tedious. For example, multiple tools are needed to loosen and tighten the die fixing bolts. This process often takes several hours or even longer, thus reducing the die change speed of the stamping dies above the worktable. To address this issue, we propose a CNC stamping machine worktable with a quick die change structure. Utility Model Content

[0004] The purpose of this invention is to provide a CNC punching machine worktable with a quick mold changing structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A CNC stamping machine worktable with a quick-change mold structure includes a worktable plate. A stamping mold is placed on the upper surface of the worktable plate. Two support members are provided below the worktable plate. Two fixing grooves are formed on the upper surface of the worktable plate. Two fixing blocks are fixedly connected to the bottom surface of the stamping mold. The bottom ends of the two fixing blocks extend into the interior of the two fixing grooves. Transmission grooves are formed on the inner walls of the two fixing grooves. Sliding clamps are slidably connected to the inner walls of the two transmission grooves. Moving plates are connected to the opposite sides of the two sliding clamps. Two servo motors are mounted on the outer surface of the worktable plate. Transmission screws are installed at the output ends of the two servo motors. The worktable plate has a top ejector hole, and two top plates are provided inside the top ejector hole.

[0007] In a further embodiment, both of the support members include a support base fixedly installed on the bottom surface of the workbench. Each of the two support bases has a lifting groove on one side that is close to each other. The inner walls of the two lifting grooves are slidably connected to lifting blocks. The two lifting blocks are connected to a lifting plate on one side that is close to each other.

[0008] In a further embodiment, the bottom surfaces of both top plates are connected to the upper surface of the lifting plate, and electric cylinders are installed on the inner bottom walls of both lifting slots. The extension and retraction ends of the two electric cylinders are respectively connected to the bottom surfaces of the two lifting blocks.

[0009] In a further embodiment, two positioning seats are fixedly connected to the upper surface of the worktable, and two positioning blocks are connected to the outer surface of the stamping die. The ends of the two positioning blocks that are far apart from each other extend into the interior of the two positioning seats.

[0010] In a further embodiment, threaded plates are connected to the opposite sides of the two movable plates, the outer surfaces of the two transmission screws are threaded to the inner walls of the two threaded plates, and locking grooves are provided on the opposite sides of the two fixed blocks.

[0011] In a further embodiment, the inner walls of both transmission grooves are inlaid with bearing rings, and the inner rings of the two bearing rings are respectively connected to the outer surfaces of the two transmission screws.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, through the setting of positioning blocks and positioning seats, and in conjunction with fixing blocks and fixing slots, enables the initial positioning of the stamping die during installation, facilitating subsequent automatic locking and fixing. By using a servo motor to drive the rotation of the transmission screw, and in conjunction with the linkage of the threaded plate, moving plate, and sliding clamping block, the fixing and loosening operations of the stamping die can be completed quickly. This solves the problem of complex operations in traditional die-changing methods, which require workers to use multiple tools for tedious disassembly and installation. Workers only need to start the servo motor and electric cylinder to complete the die replacement, eliminating the need for extensive manual operations and reducing the labor intensity of workers. Furthermore, the electric cylinder pushes the lifting block, lifting plate, and top plate to lift the stamping die, facilitating its removal. Attached Figure Description

[0022] Example 1

[0023] Please see Figures 1-4In this utility model, the CNC stamping machine worktable with a quick mold-changing structure includes a worktable plate 1. A stamping die 2 is placed on the upper surface of the worktable plate 1. Two support members 5 are provided below the worktable plate 1. Two fixing grooves 12 are formed on the upper surface of the worktable plate 1. Two fixing blocks 13 are fixedly connected to the bottom surface of the stamping die 2. The bottom ends of the two fixing blocks 13 extend into the interior of the two fixing grooves 12. Transmission grooves 11 are formed on the inner walls of the two fixing grooves 12. Sliding clamps 15 are slidably connected to the inner walls of the two transmission grooves 11. Moving plates 10 are connected to the opposite sides of the two sliding clamps 15. Two servo motors 7 are installed on the outer surface of the worktable plate 1. Transmission screws 8 are installed at the output ends of the two servo motors 7. Threaded plates 9 are connected to the opposite sides of the two moving plates 10. The two fixing blocks 13 are threaded to the inner walls of the two threaded plates 9 respectively. Locking grooves 14 are opened on the opposite sides of the two fixing blocks 13. The worktable 1 has a top hole 6. The top hole 6 has two top plates 18. The worktable 1 provides a platform for the installation and support of the stamping die 2 and other components. The stamping die 2 is a key component for performing stamping operations. It is used in conjunction with a CNC stamping machine to stamp and form the workpiece. When the stamping die 2 is installed, the fixing block 13 is inserted into the fixing groove 12 through the cooperation of the fixing groove 12 and the fixing block 13, which plays the role of initial positioning and fixing the die. When changing the die, the top plate 18 can rise in the top hole 6 through the top hole 6, which can lift the stamping die 2 from the worktable 1 for easy removal of the die. The electrical components of this application need to be connected to an external control system to perform operation control.

[0024] Example 2

[0025] Please see Figures 1-4 In this utility model, both support members 5 include a support base 501 fixedly installed on the bottom surface of the worktable 1. Each of the two support bases 501 has a lifting groove 504 on one side close to each other. Lifting blocks 503 are slidably connected to the inner walls of both lifting grooves 504. Lifting plates 17 are connected to the side surfaces of the two lifting blocks 503 close to each other. The bottom surfaces of both top plates 18 are connected to the upper surface of the lifting plate 17. Electric cylinders 502 are installed on the inner bottom walls of both lifting grooves 504. The telescopic ends of the two electric cylinders 502 are respectively connected to the bottom surfaces of the two lifting blocks 503. The support base 501 is the main body of the support member 5. The lifting blocks 503 can slide within the lifting grooves 504 under the push of the electric cylinders 502. Furthermore, when the lifting blocks 503 rise or fall under the push of the electric cylinders 502, the lifting plate 17 can drive the top plate 18 to move synchronously, thereby realizing the lifting of the top plate 18 and completing the lifting operation of the stamping die 2.

[0026] In a further embodiment, two positioning seats 3 are fixedly connected to the upper surface of the worktable plate 1, and two positioning blocks 4 are connected to the outer surface of the stamping die 2. The ends of the two positioning blocks 4 that are far apart from each other extend into the interior of the two positioning seats 3. The inner walls of the two transmission grooves 11 are inlaid with bearing rings 16. The inner rings of the two bearing rings 16 are respectively connected to the outer surfaces of the two transmission screws 8. Through the cooperation of the positioning seats 3 and the positioning blocks 4, when the stamping die 2 is installed, the positioning blocks 4 are inserted into the positioning seats 3, which improves the accuracy and stability of the installation of the stamping die 2. By using the setting of the bearing rings 16, the transmission screws 8 can be supported, reducing the friction when the transmission screws 8 rotate, and ensuring the smoothness of the rotation of the transmission screws 8.

[0027] The working principle of this utility model is as follows: When the stamping die 2 is changing, the servo motor 7 is started to reverse, which enables the transmission screw 8 to rotate in the opposite direction and cooperate with the threaded plate 9. This will drive the threaded plate 9, the moving plate 10 and the sliding clamping block 15 to move away from the fixed block 13, and cause the sliding clamping block 15 to exit from the locking groove 14, releasing the fixation of the stamping die 2. Then, the electric cylinder 502 in the two support members 5 is started to work. The telescopic end of the electric cylinder 502 pushes the lifting block 503 to slide upward in the lifting groove 504, and causes the lifting plate 17 to push the top plate 18 to rise. The top plate 18 lifts the stamping die 2 from the top of the worktable 1, making it convenient for the operator to take out the stamping die 2.

[0028] Next, place another stamping die 2 on the upper surface of the workbench 1, align the two fixing blocks 13 on the bottom of the stamping die 2 with the two fixing slots 12 on the workbench 1, and insert the fixing blocks 13 into the fixing slots 12. Then, start the two servo motors 7 to drive the two transmission screws 8 to rotate in the positive direction, which enables the threaded plate 9 to drive the moving plate 10 to move. The moving plate 10 pushes the sliding clamp 15 to slide in the transmission slot 11 until the sliding clamp 15 is inserted into the locking slot 14 on the side of the fixing block 13, thereby completing the quick replacement of the stamping die 2.
