Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a stamping die for high-end handbrake parts. Background Technology

[0002] A motorcycle handbrake lever is a braking device installed on the handlebars of a motorcycle. It is mainly used to control the braking of the wheels. This hand-operated braking device allows the rider to operate it using their hands.

[0003] Some higher-end handbrake handles are usually produced using stamping dies.

[0004] Chinese patent application CN202122292464.2 discloses a stamping equipment for producing iron parts for handbrake switch brackets. It states that the equipment includes: a stamping mechanism for stamping iron parts, a rotating mechanism for driving the iron parts to rotate, and a ejector mechanism for ejecting the stamped iron parts from a placement slot. The rotating mechanism is mounted on the stamping mechanism, and the ejector mechanism is fixed to the rotating mechanism. This invention, by setting a rotating mechanism, allows the motor to drive a turntable to rotate after each stamping cycle. The rotating turntable moves the next iron part to be stamped under the pressure plate, enabling the next stamping operation. This effectively shortens the stamping interval and improves stamping efficiency.

[0005] Based on a search of the aforementioned patents, we found that existing stamping dies for handbrake handles still have the following defects:

[0006] After the product stamping is completed, although the ejector mechanism pushes the product out of the placement slot, the product is still located on top of the lifting plate. It still requires manual removal of the product from the top of the lifting plate, which is inconvenient and inefficient. Therefore, to address the issue of how to better remove the stamped product, we specifically designed a stamping die for high-end handbrake components. Utility Model Content

[0026] 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.

[0027] Please see Figure 1-6 A stamping die for high-end handbrake components includes a fixed platform 1, a support plate 2 fixed to one side of the top of the fixed platform 1, a stamping cylinder 3 mounted on the top of the support plate 2, an upper die 4 mounted at the bottom of the power output shaft of the stamping cylinder 3, a die head at the bottom of the upper die 4, and the die head can enter the mold cavity of lower die 1 7 and lower die 2 701; a square through slot 5 is provided on the top of the fixed platform 1 to facilitate the rotation of an adjusting block 6, the adjusting block 6 is movably connected in the square through slot 5, and drive shafts 601 are fixed on both the front and rear sides of the adjusting block 6. Both drive shafts 601 are rotatably connected inside the fixed platform 1, and a driven gear 602 is fixed on one of the drive shafts 601. A servo motor 11 is installed on one side of the fixed platform 1. A drive gear 1102 is fixed on the power shaft 1101 of the servo motor 11. The drive gear 1102 meshes with the driven gear 602 and is placed in the cavity opened inside the fixed platform 1. When the drive gear 1102 rotates, it can drive the driven gear 602 that meshes with it to rotate. The top and bottom of the adjusting block 6 are respectively equipped with a lower mold 1 7 and a lower mold 2 701. Both the lower mold 1 7 and the lower mold 2 701 are adapted to the upper mold 4. The lower mold 1 7 is provided with an ejector plate 1201 driven by an ejector cylinder 12. The lower mold 2 701 is provided with an ejector plate 2 1301 driven by an ejector cylinder 2 13.

[0028] Please see Figure 3 In this embodiment, the adjusting block 6 has two cavities inside, and ejector cylinder 12 and ejector cylinder 13 are respectively installed in the two cavities. The top of the power output shaft of ejector cylinder 12 moves through the lower mold 7 and is fixed with ejector plate 1201. Ejector plate 1201 is closed in the closed groove opened in the mold cavity of the lower mold 7. The bottom of the power output shaft of ejector cylinder 13 moves through the lower mold 701 and is fixed with ejector plate 1301. Ejector plate 1301 is closed in the closed groove opened in the mold cavity of the lower mold 701.

[0029] Specifically, when the lower mold 7 and the upper mold 4 are used for stamping, the ejector cylinder 13 in the lower mold 701 can be activated, and the ejector plate 1301 can be used to unload the material. Conversely, when the lower mold 701 and the upper mold 4 are used for stamping, the ejector cylinder 12 in the lower mold 7 can be activated, and the ejector plate 1201 can be used to unload the material. The two actions can be performed simultaneously without affecting each other.

[0030] Please see Figure 1 , Figure 5 and Figure 6 In this embodiment, electric telescopic rods 10 are installed on both the left and right sides of the fixed platform 1. The power output shaft of the electric telescopic rod 10 moves through the fixed platform 1 and is fixed with a limit block 14. Limit grooves 603 are opened on both the left and right sides of the adjusting block 6 at positions corresponding to the limit blocks 14. The limit blocks 14 are adapted to the limit grooves 603. An auxiliary plate 1401 is fixed on the top and bottom of one side of each limit block 14. The side of the auxiliary plate 1401 away from the limit block 14 moves through the fixed platform 1.

[0031] Specifically, after the electric telescopic rod 10 is started, it can drive the limiting block 14 to engage or disengage from the limiting groove 603, thereby fixing or releasing the limiting of the adjusting block 6, so as to facilitate the driving of the servo motor 11 and drive the adjusting block 6 to rotate. At the same time, an auxiliary plate 1401 is set on the limiting block 14. The auxiliary plate 1401 moves with the limiting block 14, which can help stabilize the limiting block 14 and also provide a certain support effect to ensure the stability of the adjusting block 6.

[0032] Please see Figure 1 and Figure 3 In this embodiment, the left and right sides of the adjusting block 6 are respectively away from the left and right sides of the inner wall of the square through groove 5, and the front and rear sides of the adjusting block 6 are respectively slidably attached to the front and rear sides of the inner wall of the square through groove 5.

[0033] Specifically, the left and right sides of the adjusting block 6 are far away from the square through groove 5, which facilitates the rotation of the adjusting block 6 and avoids affecting the rotation of the adjusting block 6. At the same time, the front and rear sides of the adjusting block 6 slide and fit against the front and rear sides of the inner wall of the square through groove 5, which can ensure the stability of the front and rear sides of the square through groove 5.

[0034] Please see Figure 1 In this embodiment, a support frame 8 is fixed to the bottom of the fixed platform 1, and a storage basket 9 is slidably connected to the top of the support frame 8. The storage basket 9 is located at the bottom of the adjusting block 6, and a handle is fixed to one side of the storage basket 9.

[0035] Specifically, a support frame 8 is installed at the bottom of the fixed platform 1 to support the platform 1. A sliding, retractable storage basket 9 is installed on the support frame 8 to facilitate the collection of fallen handbrake parts for subsequent unified processing, such as polishing, to achieve the desired finish. Figure 7 The handbrake lever shown is used on a high-end motorcycle.

[0036] When using:

[0037] Place the handbrake part blank into the cavity of the lower mold 7, start the stamping cylinder 3, the power output shaft of the stamping cylinder 3 drives the upper mold 4 to move down, and complete the stamping of the blank in the lower mold 7. After the stamping is completed, the upper mold 4 moves up away from the lower mold 7 by the drive of the stamping cylinder 3.

[0038] Start the two electric telescopic rods 10. The power output shaft of the electric telescopic rod 10 retracts, thereby driving the limit block 14 out of the limit groove 603. Then start the servo motor 11. The power shaft 1101 of the servo motor 11 drives the drive gear 1102 to rotate. The drive gear 1102 drives the driven gear 602 to rotate. The driven gear 602 rotates and drives the transmission shaft 601 to rotate. The rotation of the transmission shaft 601 drives the adjusting block 6 to flip. This causes the lower mold 1 7 to bring the handbrake part that has been stamped to the bottom of the adjusting block 6, and the lower mold 2 701 to the top of the adjusting block 6. Then start the electric telescopic rod 10 again. The power output shaft of the electric telescopic rod 10 extends and pushes the limit block 14 back into the limit groove 603, thereby stabilizing the adjusting block 6 again.

[0039] At the same time, the handbrake part blank can be put into the lower mold 2 701, and the stamping cylinder 3 can be started to complete the stamping. The handbrake part that has been stamped in the lower mold 1 7 can be pushed by the ejection cylinder 12. The power output shaft of the ejection cylinder 12 pushes the ejection plate 1201 to push the handbrake part that has been stamped in the lower mold 1 7, thereby pushing the handbrake part out of the mold cavity of the lower mold 1 7 and falling into the storage basket 9 under the influence of gravity.

[0040] After the handbrake part blank in the second mold 701 is stamped, the adjustment block 6 can be flipped by the servo motor 11, so that the second mold 701 is located at the bottom of the adjustment block 6 and the material is unloaded by the ejector cylinder 13. The first mold 7 is located at the top of the adjustment block 6 to unload and stamp the material.

[0041] In summary, using this stamping die allows for simultaneous stamping and material handling without interference, effectively improving product stamping efficiency.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
