[0009] A clamping tool is used to clamp the upper module and the lower module.

[0010] Preferably, the tool further includes:

[0011] A striking tool is used to strike the ear piece so that the ear piece fits tightly against the protrusion of the upper module.

[0012] Preferably, the lower part of the upper module has a profile that fits with the gear ring part, and six protrusions for bending the six lugs of the gear ring part;

[0013] The upper module also has a hole at its bottom center, which slides with the shaft of the lower module to serve a positioning function.

[0014] Preferably, the lower module has a step in the middle, which positions the gear ring part;

[0015] The lower module has a shaft on its step, which slides with a hole in the upper module to serve a positioning function.

[0016] Preferably, the side of the lower module has a certain bevel angle, which is beneficial for manually hammering the lugs of the gear ring part during manual operation.

[0029] Please see Figures 1-9This application provides a manual bending tool for small parts, which places the gear ring parts in a designated position during the production process of the gear ring parts. The bending tool includes an upper module 1 that is attached to the upper surface of the gear ring parts and a lower module 2 that is attached to the lower surface of the gear ring parts. The upper module and the lower module are positioned by a shaft through a central hole. The gear ring parts 3 are positioned by a step on the lower module.

[0030] The upper module is a metal block that requires heat treatment to achieve a certain degree of hardness. The lower part of the upper module has a profile that fits with the gear ring parts and six protrusions for bending the six lugs of the gear ring parts. The upper module has a hole at the bottom center, which slides with the shaft of the lower module to serve a positioning function.

[0031] The lower module is a metal block that requires heat treatment to achieve a certain level of hardness. It has a step in the middle that positions the gear ring parts. Above the step is a shaft that slides into a hole in the upper module, also serving a positioning function. The lower module has a slight bevel on its side; this bevel facilitates manual hammering of the lugs during operation.

[0032] The manual bending tool provided in this application is easy to position and simple to operate, and can solve the bending problem of small gear ring parts. This application positions the gear ring parts, flanging the shape to complete the bending of the parts, which not only improves work efficiency, but also ensures the processing quality of the parts.

[0033] In other embodiments of this application, a method for using a manual bending tool for small parts provided in this application will be described in further detail.

[0034] Step 1: Place the lower module on the operating table or platform, align the center hole of the part to be processed with the positioning step in the middle of the lower module and insert it;

[0035] Step 2: Align the hole at the bottom of the upper module with the shaft at the top of the lower module, and rotate them simultaneously so that the protrusion of the upper module aligns with the lug of the gear ring part. Press the upper and lower modules together to tighten and compact the part. If necessary, use a clamping tool to hold it in place.

[0036] Step 3: Flip the compressed upper and lower modules over. Using the optimal force, angle, and method for manual operation, tap the six lugs on the gear ring part to ensure they are tightly fitted to the six protrusions on the upper module. The worker must use a wooden mallet or rubber / plastic rod during this process to better protect the part's surface and ensure the quality of the part's molding.

[0037] Step 4: After confirming that the part is completely aligned with the six protrusions on the upper module and there is no springback after a long period of time, rotate the upper module to rotate the six protrusions on the upper module to an angle that is completely offset from the lugs of the part before removing the upper module. Otherwise, forcibly removing the upper module will damage or destroy the part.
