Split type uncoiling brake disc

Abstract

The invention relates to a split type uncoiling brake disc comprising a brake disc body and a transition shaft sleeve. The transition shaft sleeve is of a step type structure and comprises a first sleeve cylinder, a second sleeve cylinder and a third sleeve cylinder, wherein the outer diameters of the first sleeve cylinder, the second sleeve cylinder and the third sleeve cylinder are decreased in sequence. The second sleeve cylinder is sleeved with the brake disc body. The split type uncoiling brake disc further comprises two pieces of abrasion resistant layers. Each abrasion resistant layer comprises a plurality of abrasion resistant pieces. A protruding block is arranged on each abrasion resistant piece. A plurality of sliding grooves corresponding to the protruding blocks are formed in the brake disc body. The brake disc body and the transition shaft sleeve are of a split type structure, so that replacement and maintenance are better facilitated, manufacturing is easy, and the using cost is low; the abrasion resistant layers are mounted to strengthen the abrasion resistance of the brake disc body, so that the brake disc body is not liable to be abraded; the abrasion resistant layers are composed of the multiple abrasion pieces, and each abrasion resistant piece and the brake disc body are matched independently, when abrasion or fracture occurs, the abrasion resistant pieces can be replaced specifically, operation is convenient and rapid, and the replacement cost is low; and meanwhile the sliding grooves further can take a certain effect on heat dissipation.

Description

technical field [0001] The invention relates to an unwinding brake system, in particular to a split type unwinding brake disc. Background technique [0002] Coiled hot-rolled materials must be pickled to remove the oxide scale on the surface of the material before cold-rolling to correct the accuracy. This process requires the uncoiler to uncoil and level the entire coil and then soak it in the acid tank. The production needs to slow down. When running or stopping welding traction, it must be realized by means of a braking device. Such an uncoiling braking system came into being. The general uncoiling braking system adopts integral castings as the brake disc, and after machining and assembling, the brake disc is clamped by the left and right brake shoes to complete the deceleration or shutdown of the uncoiling machine. Uncoiling brake discs in technology such as figure 1 As shown, the brake disc 01 and the transition bushing 02 are integrally formed. If they are damaged du...

Such an uncoiling braking system came into being. The general uncoiling braking system adopts integral castings as the brake disc, and after machining and assembling, the brake disc is clamped by the left and right brake shoes to complete the deceleration or shutdown of the uncoiling machine. Uncoiling brake discs in technology such as figure 1 As shown, the brake disc 01 and the transition bushing 02 are integrally formed. If it is damaged during use, it needs to be replaced as a whole. The replacement cost is high and the use is cumbersome.
