Guardrail plate end corner angle blunting device

Abstract

The invention is suitable for the technical field of guardrail plate edge and corner grinding equipment, and provides a guardrail plate end edge and corner grinding device which comprises a grinding mechanism and a driving motor, the grinding mechanism comprises a base, a platform arranged at the top of the base, a steel wire roller rotationally connected to the top of the platform and the driving motor for driving the steel wire roller to rotate, and the steel wire roller is rotationally connected to the top of the platform; the driving motor is fixedly connected to the top of the platform. The clamping tool used for clamping the workpiece comprises a first frame and a second frame, a rotating shaft is arranged at the front end of the first frame, the rotating shaft is rotationally connected to a main frame body, a stress rod is arranged at the other end of the first frame, and a space cam for driving the stress rod to reciprocate up and down is arranged on the main frame body. According to the device, the steel wire roller structure is additionally arranged, edge and corner parts of the guardrail plate are blunted, meanwhile, an automatic rotating and clamping tool is additionally arranged, when the guardrail plate is blunted, rotating and edge changing are automatically conducted, automatic blunt grinding of the edge and corner parts of the guardrail plate is achieved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of equipment for blunting edges and corners of guardrail boards, in particular to a device for blunting edges and corners of guardrail board ends. Background technique [0002] The highway guardrail produced by spraying anti-corrosion process will rust if the substrate is exposed. The rusted parts will slowly spread with the intrusion of rainwater, resulting in anti-corrosion failure. In addition to bumping, the reason for the exposure of the substrate is the residual burrs and sharp corners formed during the production process on the two edges and both ends of the guardrail substrate. The sharp burrs and corners are difficult to compare by spraying. good coverage. Among them, the small edge burrs can be removed by shot blasting, but the larger burrs and sharp edges are difficult to completely remove by shot blasting, and the edges and corners formed by cutting the two ends of the guardrail are very sharp, ...
