[0016] In order to make the purpose, content and advantages of the utility model clearer, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments.

[0017] This embodiment provides a bending die for hot bending of a handle, and its structure is as follows: Figure 1a to 1c As shown in Figure 2, it mainly includes a left handle 1, a left side plate 2, a mold body 3, a central axis 4, a roller 5, a screw 6, a right handle 7 and a right side plate 8. Two shaped holes with different depths are processed on the left and right sides of the mold body 3. The right handle 7, the right side plate 8, the right half of the mold body 3, the central axis 4, the roller 5 and the screw 6 constitute the right module; the left handle 1, the left side plate 2, the left half of the mold body 3, the central axis 4, the roller 5 and the screw 6 constitute the left module.

[0018] The right module is used to realize the L-shaped bending process. After a central shaft 4 passes through a roller 5, the end thread of the central shaft 4 is screwed into the threaded hole of the right handle 7. The rotating axis of the right handle 7 is respectively inserted into the corresponding holes of the mold body 3 and the right side plate 8. The right side plate 8 is fixed to the mold body 3 with screws 6. The bending mold groove of the right module is an L-shaped structure.

[0019] The left module is used to realize the S-shaped bending process. After another central shaft 4 passes through another roller 5, the end thread of the central shaft 4 is screwed into the threaded hole of the left handle 1, and the rotating axis of the left handle 1 is respectively inserted into the corresponding holes of the mold body 3 and the left side plate 2. The left side plate 2 is fixed to the mold body 3 with screws 6. The bending mold groove of the left module is an S-shaped structure.

[0020] The process of hot bending the handle using the above mold is as follows:

[0021] Use a clamp to put the heated handle into the right shaping hole of the mold body 3, pull the right handle 7 downward until the right handle limit block contacts the upper surface of the mold body 3, and the roller 5 in the right module moves with the right handle 7. Under the action of the roller 5, the handle is gradually bent along the R18 arc-shaped cavity. After forming, it stays for 1 to 2 seconds to make the R18 arc-shaped cavity of the right handle 7 fully contact with the handle blank to ensure that the forming meets the requirements, pull up the right handle 7, take out the handle, and complete the L-shaped bending process. Figure 3 shown.

[0022] Subsequently, the handle is transferred to the left shaping hole of the mold body 3 using a clamp, and the left handle 1 is pulled downward until the left handle limit block contacts the upper surface of the mold body 3. The roller 5 in the left module moves with the left handle 1. Under the action of the roller 5, the handle is gradually bent along the R18 arc-shaped mold cavity. After forming, it stays for 1 to 2 seconds. After the formed structure is stable, the left handle 1 is pulled up and the handle is taken out to complete the S-shaped bending process. Figure 4 shown.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
