[0032] When in use, the rod-shaped metal accessories are placed in the lower mold 201, and then the motor 7 and the heating tube 10 are started. The motor 7 drives the fan blades 8 to rotate to draw air into the protective shell 6, and the heating tube 10 heats and blows out the air to heat and soften the rod-shaped metal accessories, thereby improving the plasticity of the rod-shaped metal accessories for bending. After softening for a period of time, the cylinder 4 is started, and the cylinder 4 drives the upper mold 5 to move downward to press the rod-shaped metal accessories into the lower mold 201, thereby achieving bending.

[0033] Example 2: Based on Example 1, please refer to Figure 4A second mounting frame 11 is provided on the upper rear side of the support seat 2 by bolt connection, and four conveying rods 12 symmetrically distributed in pairs are rotatably connected to the second mounting frame 11, and a conveying belt 1201 is wound around two adjacent conveying rods 12 on the left and right. The conveying belt 1201 is driven by the conveying rod 12 to move and the rod-shaped metal accessories can be conveyed. A pulley 13 is connected to the conveying rod 12 on the lower right side and the output shaft of the motor 7, and a flat belt 14 is wound around the two pulleys 13. When the motor 7 is operating, the conveying rod 12 on the lower right side is rotated by the pulley 13 and the flat belt 14.

[0034] See also Figure 5 and Figure 6 A cutter 15 is provided at the lower end of the movable rod of the cylinder 4. The cutter 15 is driven downward by the cylinder 4 to cut the rod-shaped metal accessories. A support rod 16 is fixedly connected to the front side of the upper part of the support seat 2 by welding. A support plate 17 is rotatably connected to the support rod 16. When the cutter 15 cuts downward, the support plate 17 needs to cooperate with the support plate 17 to resist the rod-shaped metal accessories. A torsion spring 18 is sleeved at the front end of the support rod 16 to reset the support plate 17. The two ends of the torsion spring 18 are respectively connected to the support rod 16 and the support plate 17. Through the cooperation of the support plate 17 and the torsion spring 18, the support plate 17 can be rotated for buffering when the cutter 15 contacts the support plate 17. A protective sleeve 25 is sleeved on the support rod 16, and the protective sleeve 25 is used to protect the torsion spring 18.

[0035] See also Figure 7 and Figure 8 A push rod 19 is provided at the lower end of the movable rod of the cylinder 4. The push rod 19 is driven upward by the cylinder 4 to enable the push rod 19 to push out the rod-shaped metal accessories on the lower mold 201. A guide plate 20 is fixedly connected to the upper rear side of the support seat 2 by welding. A push rod 21 is slidably provided on the guide plate 20. The front part of the push rod 21 passes through the support seat 2. The push rod 21 moves forward to push out the rod-shaped metal accessories on the lower mold 201. Two elastic members 22 are connected between the push rod 21 and the guide plate 20. The two elastic members 22 are respectively sleeved on the left and right parts of the push rod 21.

The collection box 23 is used to collect the rod-shaped metal accessories pushed out by the push rod 21.

[0036] In actual use, the rod-shaped metal parts are placed between the two conveyor belts 1201, and then the motor 7 is started. While the motor 7 is running, the conveyor rod 12 is driven to rotate through the pulley 13 and the flat belt 14, so that the conveyor belt 1201 transports the rod-shaped metal parts to the left to the lower mold 201, realizing automatic loading. At the same time, the softening and loading operations can be carried out simultaneously, saving time and facilitating the subsequent rapid bending operation. When the rod-shaped metal parts are softened and the cylinder 4 is started for the bending operation, the cylinder 4 simultaneously drives the upper mold 5, the cutter 15 and the ejector rod 19 to move downward, and the cutter 15 first contacts the rod-shaped metal parts, so that the excess part of the rod-shaped metal parts is cut off, and no other equipment is needed. The upper mold 5 is cut off, and when the upper mold 5 moves down, the upper mold 5 contacts the push rod 21, and the push rod 21 moves backward, and the elastic member 22 is compressed accordingly, making room for the upper mold 5 to move. After the upper mold 5 moves down to bend the rod-shaped metal accessories, the cylinder 4 drives the upper mold 5, the cutter 15 and the push rod 19 to move up. At this time, the push rod 19 moves up to lift the rod-shaped metal accessories on the lower mold 201, and then the upper mold 5 is disengaged from the push rod 21. Under the restoring elastic force of the elastic member 22, the push rod 21 resets forward to push the lifted rod-shaped metal accessories out of the lower mold 201, thereby realizing automatic material return, which helps to improve work efficiency, and the pushed rod-shaped metal accessories are collected in a centralized manner through the collection box 23.

Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
