Description

Technical Field

[0001] The utility model relates to the technical field of safety protection equipment for bending machines, and specifically refers to a safety protection device for a building steel structure bending machine. Background Technique

[0002] In the field of building steel structure processing, as one of the key equipment, bending machines are widely used in the forming processing of various steel structure parts. However, with the increasing diversification of the size, shape and processing requirements of steel structure parts, traditional bending machines face many challenges during operation, especially in terms of safety protection, where there are obvious deficiencies.

[0035] Working principle: First, place the bottom plate 1 in the working area and use the positioning holes on the bottom plate for precise positioning and fixation to ensure the stability of the entire device. The auxiliary box 3 is fixed on the bottom plate 1 through the base 2. The arc-shaped plate 1 4 on it is connected to the clamping member 21 through the resilient band 20 and the rotating shaft 19 to form a certain elastic support structure to adapt to steel structures of different shapes and sizes. When the steel structure is placed below the clamping plate 6, start the first rotating motor 7. The first rotating motor 7 drives the two screws 8 to rotate. Since the screw 8 is threadedly connected to the clamping plate 9 and the rear end of the clamping plate 9 slides in the chute through the limiting block 10, the rotation of the screw 8 will cause the clamping plates 9 to move towards each other, thereby driving the arc-shaped plate 2 11 to closely fit the surface of the steel structure to achieve stable clamping. The rubber pad 12 is provided to increase the friction and prevent the steel structure from sliding during the bending process. Before the bending starts, by controlling the operation of the second rotating motor 22, the gear rod 23 connected to its output end meshes with the tapered tooth disc 24 to drive the screw to rotate. Since the screw is connected to the gear ring 25 and the lead screw 27, the lead screw 27 moves in the groove under the support of the roller ring 26 to meet the requirements of different bending angles. The cylinder 13 on the support block 5 drives the telescopic rod 15 and the arc-shaped plate 3 16 to move forward. The rolling of the first roller 14, the second roller 17 and the third roller 18 provides stable support and guidance for the steel structure during the bending process, reducing friction and resistance. After the steel structure is stably clamped and the position is adjusted, the bending operation is performed on the steel structure. At this time, the fastening assembly ensures that the steel structure will not move, and the auxiliary box and the support block system provide the necessary support and guidance to ensure the safety and precision of the bending process. After the bending is completed, operate the first rotating motor 7 and the second rotating motor 22 in reverse to release the steel structure and adjust it back to the initial position. Then, by operating components such as the cylinder 13, the support block system is restored to the standby state to prepare for the next operation.
