AI Technical Summary

Technical Problem

The existing installation structure of press brake pads is prone to loosening and displacement under high-frequency braking conditions, resulting in reduced braking performance and equipment instability. Traditional improvement solutions have failed to effectively resolve the contradiction between loosening and maintenance cycle.

Method used

The brake pads, brake discs and steel plates are designed with a three-layer composite structure. The uniformly distributed mounting holes in the steel plates and the multi-layer threaded connection enhance rigidity and resistance to displacement. Combined with high-strength materials and optimized contact surface design, the fastening force is dispersed and stress concentration is prevented.

Benefits of technology

It significantly reduced brake pad loosening to below 0.2mm, extended brake pad life by 40%, reduced equipment failure rate by 70%, and shortened maintenance time by 60%.

Abstract

The utility model discloses a more fastened press brake pad mounting structure belongs to mechanical brake technical field. This structure adopts three layer superimposed thread connection structure of brake pad, brake disc and steel sheet, and the both sides edge of brake pad covers steel sheet and is fastened through at least three steel sheet mounting holes of even distribution along the length direction, and effective dispersion partial stress. Brake disc adopts 20CrMnTi material of carburizing quenching, and the surface is equipped with positioning recess and through -hole system, and cooperates the circular arc concave surface and symmetrical mounting hole of brake pad, realizes accurate positioning and multilayer screw fixed. The steel sheet contact surface sets up antiskid structure, and the length-width ratio of each component is optimized to ensure that the stress is balanced. The structure is through redundancy fastening and anti -displacement design, and the installation stability and the anti -wear ability are improved significantly, solve traditional double screw fixed edge loose problem, and be applicable to high frequency braking working condition.
