Description

Technical Field

[0001] The utility model relates to the technical field of wire pay-off drums, in particular to a brake wire pay-off drum for a rolling welding machine. Background Art

[0002] The steel cage is made by winding and welding the ring bars on the longitudinal bars according to a certain pitch. During the production process, the pay-off drum and the roll welding machine need to be coordinated to complete the work. During the production process, the pay-off drum needs to be braked according to the on-site production situation.

[0003] When braking the pay-off reel, it is usually necessary to use the cooperation of brake disc and brake pad to brake the pay-off reel. The brake disc and brake pad mainly use friction to brake the pay-off reel. The fast-rotating pay-off reel still has a certain inertia and will produce a certain rotation when braking. At the same time, the brake disc and brake pad will show greater wear after long-term friction. When the wear is severe, the braking effect of the pay-off reel will be poor.

[0004] Therefore, we propose a brake pay-off disc for a seam welding machine. Utility Model Content

When the turntable 3 is successfully braked, the broken movable gear 11 can be replaced to ensure subsequent normal use.

[0026] The working principle of the utility model is as follows: when the turntable 3 needs to be braked, the two brake pads 7 are controlled to press against the surface of the brake disc 5 to utilize the friction force to brake the turntable 3. Before the turntable 3 is braked, the movable cylinder 15 and the movable pressure block 16 are controlled to extend to one side of the brake disc 5 until they are in contact with the deceleration plate 9. When the movable pressure block 16 is in contact with the deceleration plate 9, the deceleration plate 9 is in close contact with the movable pressure block 16 under the action of the spring 18, the opening rod 19 and the movable block 21 to increase the friction between the deceleration plate 9 and the movable pressure block 16.
