Description

Technical Field

[0001] This utility model relates to the technical field of metal cutting equipment, specifically to a cutting device with an easily replaceable blade. Background Technology

[0002] A bicycle, also known as a pedal bike or bicycle, can be categorized into steering system, drive system, and braking system based on the working characteristics of each component. Many bicycle parts require punching and cutting, such as disc brakes, freewheels, front fenders, and rear fenders.

[0003] Patent (CN222220866U) discloses a blanking die and blanking device. The blanking die includes a lower die assembly and an upper die assembly. During use, the base material is placed on the female die of the lower die assembly. The upper die assembly moves downward as a whole under the drive of the lifting mechanism. Since the lower end face of the male die is lower than the lower end face of the punch and the upper die plate, the lower end face of the male die first presses down on the base material on the female die. As the lifting mechanism continues to apply pressure, the fixing plate continues to move downward against the elastic force of the elastic reset member, driving the punch and the upper die plate to continue to descend. The punch is inserted into the blanking hole on the female die, cutting the portion of the base material corresponding to the blanking hole to form a hole. The upper die plate is fitted onto the outside of the female die, cutting off the material from the outer edge of the female die, ultimately forming a product with a certain shape and size and a hole. Using this blanking die and blanking device, a product with a certain shape and size and a hole can be obtained in one blanking operation. The operation is simple and the production efficiency is high.

[0004] The blanking die and blanking device in the above patent can only blank products of the same size and shape. If you want to blank products of other sizes and shapes, you need to replace the blanking cutter head of the upper die and the female die in the lower die. However, replacing the blanking cutter head and female die in the above blanking die requires completely disassembling the blanking die, which is quite cumbersome. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a cutting device with an easily replaceable cutter head, including a support frame 1. A cylinder 2 is vertically mounted at the top center of the support frame 1. A connecting block 3 is mounted on the output shaft of the cylinder 2. A punching cutter head 4 and a base 5 are mounted below the connecting block 3 on the support frame 1. The top of the punching cutter head 4 has a first mounting groove 401 that matches the connecting block 3. The top center of the base 5 has a second mounting groove 501 that matches the female mold 6 below the punching cutter head 4. The bottom of the punching cutter head 4 has a male mold that matches the female mold 6. Several first insertion mechanisms 7 are provided inside the punching cutter head 4 outside the first mounting groove 401. Several second insertion mechanisms 8 are provided inside the base 5 outside the second mounting groove 501. The first insertion mechanism 7 and the second insertion mechanism 8 have the same structure. The first insertion mechanism 7 includes a rotatably configured ball screw 9. A screw nut 10 is movably fitted on the outer wall of the ball screw 9. A support ring 11 is provided on the outer wall of the screw nut 10. Several insertion rods 12 are provided on the outer wall of the support ring 11 outside the ball screw 9. The insertion rods 12 are parallel to the ball screw 9. The outer wall of the connecting block 3 and the outer wall of the female mold 6 are provided with slots that match the insertion rods 12. The first insertion mechanism 7 also includes a rotatably configured worm gear 14. A worm wheel 15 that meshes with the worm gear 14 is fitted on one end of the outer wall of the ball screw 9. A handwheel 16 is provided on one end of the worm gear 14. The handwheel 16 extends to the outside of the punching head 4 and the base 5.

[0024] In one embodiment, a guide block 13 is provided at the top of the outer wall of the support ring 11. Both the punching head 4 and the base 5 have movable cavities that match the support ring 11. The ball screw 9 is rotatably disposed inside the movable cavity. The inner wall of the movable cavity has a guide groove that matches the guide block 13. The inner walls of the first mounting groove 401 and the second mounting groove 501 both have through holes that match the insert rod 12. The through holes extend into the movable cavity. During the rotation adjustment of the ball screw 9, the screw nut 10 can move along... The ball screw 9 reciprocates horizontally within the movable cavity, causing the support ring 11 to reciprocate horizontally within the movable cavity. The support ring 11 drives the insertion rod 12 to reciprocate horizontally. The insertion rod 12 passes through the through hole from the movable cavity and enters the first mounting groove 401 and the second mounting groove 501, ensuring that the insertion rod 12 can be fixed and released from the insertion of the connecting block 3 and the female mold 6. This enables quick assembly and disassembly of the connecting block 3 and the punching head 4, as well as quick assembly and disassembly of the female mold 6 and the base 5.

[0025] In one embodiment, the handwheel 16 of the first insertion mechanism 7 extends above the punching head 4, facilitating rotational adjustment of the handwheel 16 from the top of the punching head 4. This effectively prevents damage to the handwheel 16 when the punching head 4 applies downward punching treatment to the product. The handwheel 16 of the second insertion mechanism 8 extends below the base 5, and the base 5 has several support legs at its bottom. These support legs provide support at the bottom of the base 5, effectively suspending the base 5. This ensures that the handwheel 16 can be rotated and adjusted normally, while also ensuring that the waste material from the punching process on the die 6 falls directly from the die 6 to the base 5, facilitating cleaning and effectively preventing waste material from accumulating inside the base 5 below the die 6.

[0026] In one embodiment, the support frame 1 includes a top plate 101, with a plurality of support rods 102 vertically arranged at the bottom of the top plate 101, the cylinder 2 vertically arranged at the top of the top plate 101, and the connecting block 3 arranged below the top plate 101. The support rods 102 provide overhead support for the top plate 101, ensuring the safety and stability of the cylinder 2 and the connecting block 3.

[0027] The working principle of this utility model:

[0028] Refer to the instruction manual appendix Figures 1-5This utility model comprises a support frame 1, a cylinder 2, a connecting block 3, a punching head 4, a base 5, a female mold 6, a first insertion mechanism 7, and a second insertion mechanism 8. The support frame 1 provides overhead support for the cylinder 2. The connecting block 3 connects and supports the punching head 4 at the output end of the cylinder 2. The base 5 connects and supports the female mold 6 below the punching head 4. The female mold 6 is used to place and support the product to be punched. The male mold at the bottom of the punching head 4 cooperates with the female mold 6 to perform punching processing on the product to be punched. The first mounting slot 401 provides space for the connecting block 3 and the punching head 4 to be installed and connected. The second mounting slot 501 provides a space for the installation of the female mold 6 on the top of the base 5. An elastic lifting component can be provided inside the second mounting slot 501. The elastic lifting component passes through the female mold 6 to provide elastic support for the product. The product after punching can be ejected from the female mold 6, which is convenient for removing the punched product. Alternatively, the elastic lifting component can be omitted, and the operator can manually remove the product or use a robot to remove the product after the punching process is completed.

[0029] The first insertion mechanism 7 is used for quick assembly and disassembly of the punching head 4 and the connecting block 3, facilitating the replacement of the punching head 4. The second insertion mechanism 8 is used for quick assembly and disassembly of the female mold 6 and the base 5, facilitating the replacement of the female mold 6 to match the punching head 4. During use, the first insertion mechanism 7 and the second insertion mechanism 8 can be adjusted by rotating the ball screw 9, causing the screw nut 10 to move horizontally along the ball screw 9. The screw nut 10 can drive multiple insertion rods 12 to move horizontally via the support ring 11. By adjusting the rotation direction of the ball screw 9, the horizontal reciprocating adjustment of the screw nut 10 can be achieved, thereby achieving the horizontal adjustment of the insertion rods 12. The horizontal reciprocating adjustment of the insertion rod 12 allows it to be inserted and withdrawn from the slot. When the insertion rod 12 is inserted into the slot, it can limit and fix the connection between the connecting block 3 and the punching head 4, as well as the connection between the female mold 6 and the base 5. When the insertion rod 12 is withdrawn from the slot, it can release the limiting and locking state of the connecting block 3 and the punching head 4, as well as the limiting and locking state of the female mold 6 and the base 5. This facilitates the replacement of the punching head 4 and the matching replacement of the female mold 6. The female mold 6 and the male mold can be selected according to the product shape to be processed, facilitating the punching processing of products of different shapes and sizes.

[0030] The worm gear 14 can be rotated by turning the handwheel 16. The worm gear 14 drives the worm wheel 15 to rotate, which in turn drives the ball screw 9 to rotate. By adjusting the rotation direction of the handwheel 16, the rotation direction of the ball screw 9 can be adjusted, thereby adjusting the movement direction of the insertion rod 12. The operation is convenient and quick. Moreover, the worm gear transmission method allows for self-locking after the worm gear is rotated and adjusted, which can effectively ensure the safety and stability of the insertion limit locking.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
