[0031] Please see Figures 1-5 One embodiment provided by this utility model:
[0032] A quick-change device for bending machine dies includes:
[0033] The frame 1 has a bending mechanism 2 installed at the top inside the frame 1 and a support platform 3 installed at the bottom inside the frame 1. A limit slide 6 is provided on the top of the support platform 3. A slider 7 is slidably installed on the limit slide 6. A bending mold 4 is fixedly installed on the top of the slider 7. An operation port 5 corresponding to the position of the limit slide 6 is provided on one side of the frame 1. An installation cavity 21 is provided inside the support platform 3 in front of the limit slide 6. A movable plate 13 is slidably installed inside the installation cavity 21.
[0034] A number of fixing holes 20 are provided on the rear side of the inner wall of the mounting cavity 21, and the fixing holes 20 are connected to the interior of the limiting slide 6. The back of the movable plate 13 is fixedly installed with positioning rods 12 corresponding to the position and number of fixing holes 20, and the positioning rods 12 are slidably inserted into the fixing holes 20 at the corresponding positions.
[0035] The front of the slider 7 is provided with positioning grooves 11 corresponding to the position and number of fixing holes 20, and the positioning grooves 11 are engaged with the positioning rods 12 at the corresponding positions. Several springs 15 are fixedly installed between the front of the movable plate 13 and the front side of the inner wall of the mounting cavity 21. An operating mechanism is provided on the front of the movable plate 13.
[0036] The front of the support platform 3 has a groove 9 corresponding to the position of the mounting cavity 21. The lower side of the rear side of the inner wall of the groove 9 has a mounting groove 18, and an electric telescopic rod 19 is fixedly installed inside the mounting groove 18.
[0037] In one embodiment, the operating mechanism includes two connecting rods 14. The rear ends of the two connecting rods 14 are fixedly connected to the front of the movable plate 13. The front ends of the connecting rods 14 penetrate the support platform 3 and extend into the interior of the groove 9. An operating plate 10 is fixedly installed on the front end of the connecting rods 14. A second handle 17 is fixedly installed on the front of the operating plate 10.
[0038] In one preferred embodiment, the operation plate 10 extends downward to the front of the front port of the mounting slot 18, so that the push block 16 can contact the operation plate 10 and push it to move.
[0039] In one embodiment, the slider 7 is T-shaped and is adapted to the limiting slide 6. The T-shaped structure can enhance the stability of the slider 7 when sliding in the limiting slide 6, prevent it from falling out of the slide, ensure the accuracy and reliability of the installation of the bending die 4, keep the bending die 4 in good condition during use, and ensure the normal and stable operation of the equipment.
[0040] In one preferred embodiment, a first handle 8 is fixedly installed at one end of the slider 7 to facilitate operation of the slider 7.
[0041] In one embodiment, an anti-slip layer is provided on the outer surface of the second handle 17, which can increase the friction between the hand and the handle, prevent slippage during operation, and allow the operator to pull the second handle 17 more stably and safely to smoothly complete the bending die 4 replacement operation.
[0042] In one preferred embodiment, a push block 16 is fixedly installed at the drive end of the electric telescopic rod 19, which can effectively transmit the driving force of the telescopic rod to other components, so that the operating plate 10 can move smoothly and the position of the positioning rod 12 can be adjusted.
[0043] The working principle of this utility model is as follows: All electrical components mentioned are electrically connected to the main controller and power supply. The main controller can be a computer or other conventionally known control device. Existing publicly available power connection technologies are not detailed here. Parts not mentioned in this device are the same as or can be implemented using existing technologies. When the bending die 4 needs to be replaced, the operator can directly operate the second handle 17 located inside the groove 9, pulling the second handle 17 outwards. This operation causes the operating plate 10 to move synchronously. The displacement of the operating plate 10 pulls the movable plate 13 forward within the mounting cavity 21 via the connecting rod 14. During the movement of the movable plate 13, it exerts a squeezing effect on the spring 15. As the movable plate 13 continues to move, the positioning rod 12 disengages from the positioning groove 11 on the slider 7. After the slider 7 loses the locking and limiting contact between the positioning rod 12 and the positioning groove 11, the operator can directly pull the slider 7 from the limiting slide 6 via the first handle 8 on the side of the device. The movement of slider 7 synchronously drives the bending die 4 to move, allowing slider 7 and bending die 4 to be removed together from the side of the equipment. When changing to a different specification of bending die 4, first slide slider 7 at the bottom of bending die 4 directly into the limiting slide rail 6. After slider 7 is inserted into place, release the limiting force on the second handle 17. At this time, the elastic restoring force of spring 15 drives positioning rod 12 through movable plate 13 to engage with positioning groove 11 on slider 7, firmly locking slider 7 inside the limiting slide rail 6, thus ensuring the stability of bending die 4 at the top of slider 7 during use. This equipment abandons the traditional bolt fixing method for disassembling and assembling bending die 4, adopting a sliding insertion and locking method for installation. The entire disassembly and assembly process requires no auxiliary tools and can be completed by hand by the operator, effectively reducing the difficulty of changing bending die 4, improving replacement efficiency, reducing equipment downtime, and thus improving production efficiency.
[0044] In use, when disassembling the bending die 4, in addition to manually operating the second handle 17 to adjust the position of the positioning rod 12, the electric telescopic rod 19 can be controlled to push the push block 16, thereby moving the operating plate 10 outward, thus adjusting the position of the positioning rod 12. Compared to direct manual operation, this mechanically driven method of changing the position of the positioning rod 12 has significant advantages, effectively saving time and manpower. This design provides diversified operation methods for disassembling and assembling the bending die 4. Even if the mechanical drive structure fails, the manual operation method can still ensure the normal progress of disassembly and installation, greatly improving the practicality of the equipment.
[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
