Description

Technical Field

[0001] The utility model relates to the technical field of scroll spring production equipment, in particular to a scroll spring curling machine. Background Art

[0002] A spiral spring, also known as a spring, is a spring with one end fixed and the other end acting on a torque. This spring is made of a thin and elongated material of equal cross-section, forming a flat spiral line. Under the action of torque, the spring material produces bending elastic deformation, causing the spring to twist in the plane. The size of the deformation angle is proportional to the applied torque.

[0003] During the production process of the spiral spring, a curling machine is required to shape it. After the spiral spring is curled and formed, the existing curling machine cannot quickly remove the formed spiral spring. At the same time, the formed spiral spring still has a high temperature, which is not convenient for collection. Utility Model Content

[0029] Embodiment 1

[0030] Combined with Figure 1-3 A curling block 3 is rotatably connected to the vertical plate 2, and a plug-in slot 4 is provided on the side of the curling block 3. A feeding mechanism is provided on the right side of the curling block on the front of the vertical plate 2, and the feeding mechanism adopts a horizontally arranged conveying roller 15. A driving component is provided on the back of the vertical plate 2, and the driving component drives the curling block 3 to rotate. The driving component includes a motor 7 and a synchronous wheel 8. The curling block 3 is rotatably connected to the vertical plate 2 through a connecting shaft, and the rear end of the connecting shaft is exposed from the vertical plate 2. A motor 7 is provided on the rear side of the vertical plate 2, and a synchronous wheel 8 is provided on the output end of the motor 7 and the rear end of the connecting shaft, and the synchronous wheels 8 are connected by a synchronous belt.

[0031] When in use, the horizontally arranged conveying roller 15 transports the material of the spiral spring, and one end thereof is inserted into the connecting groove 4. At this time, the motor 7 rotates, and the curling block 3 is driven to rotate through the synchronous wheel 8 and the synchronous belt, so that the raw material is curled into a spiral spring.

[0032] Combined with Figure 3 A push ring 5 is provided on the outer side of the curling block 3, and a push mechanism is provided on the vertical plate 2, and the push mechanism drives the push ring 5 to move in a direction perpendicular to the vertical plate 2;

[0033] The ejection mechanism includes an electromagnet 11, a transmission rod 12 and a transmission plate 13. The transmission rod 12 is slidably connected to the vertical plate 2. The transmission plate 13 is provided at the rear side of the vertical plate 2. The front end of the transmission rod 12 is connected to the push ring 5, and the rear end is connected to the transmission plate 13. A spring 14 is provided between the transmission plate 13 and the vertical plate 2.

[0034] Two sets of transmission rods 12 and springs 14 are provided between the push ring 5 and the transmission plate 13;

[0035] The spring 14 is sleeved on the outside of the transmission rod 12 .

[0036] After the spiral spring is formed, the electromagnet 11 is energized to generate magnetic force, which adsorbs the transmission plate 13. The transmission plate 13 squeezes the spring 14 to move toward the vertical plate 2, and drives the push ring 5 to move forward through the transmission rod 12, pushing the spiral spring out of the curling block 3. After the power is turned off, the magnetic force disappears, and the push ring 5 returns to its initial position under the action of the spring 14. The two sets of transmission rods 12 and springs 14 ensure the transmission effect, and the spring 14 is sleeved on the outside of the transmission rod 12 to ensure the expansion and contraction direction of the spring 14.
