Description

Self-adaptive guide mechanism for steel plate side edge grinding and brushing

Technical Field

The utility model relates to a processing technology field is handled in rust cleaning deoxidization skin on steel sheet surface, in particular to a self-adaptation guiding mechanism for steel sheet side scrubbing.

Background

At present, steel rust removal is basically performed by manufacturers in an acid pickling mode, but the acid pickling rust removal mode can generate sewage with high pollution degree, cause serious pollution to the environment and do not meet the long-term requirement of environmental protection; at present, the descaling of steel is realized by adopting a descaling roller, namely a physical grinding and brushing mode such as a brush roller, and the descaling roller can adopt the following patent numbers: 201720567999.7, the rust removing roller rubs the rust of steel through abrasive wires, for example, the steel surface and the steel plate side can be rubbed through the abrasive wires of the scale breaking roller, for the steel plate side rubbing, it is necessary to ensure that the center line of the steel plate always keeps the same position when the steel plate travels, the steel plate side rubbing is controlled by a coiler at the tail end of the steel plate receiving, and pushing mechanisms are arranged on both sides of the coiler, so that the steel plate can be rolled on the receiving roller smoothly without deflection; however, the walking resistance of the steel plate can be increased in the mode, the steel plate walks slowly and can still generate deviation sometimes, and the deviation of left and right displacement generated in the process of grinding and brushing the side edge of the steel plate is corrected at the tail end, so that a vacuum belt can be generated in the process of grinding and brushing the side edge of the steel plate, for example, the steel plate deviates from a central line in the process of grinding and brushing, one side of the steel plate is excessively close to a nearby scale breaking roller, the other side of the steel plate is far away from the nearby scale breaking roller, namely, a place which cannot be ground and brushed exists, the product qualification rate is influenced, and the rust removing efficiency and yield of the steel are reduced.

The patent numbers are: the prior application of CN201921587945.2 discloses a steel plate clamping and translating control device, the application of which enables a guide wheel to play a role in guiding and clamping the side edge of a steel plate, and the guide wheel follows the walking of the steel plate, so that no friction force is generated, the steel plate can always keep moving forward horizontally, no left-right deflection is generated, and the brushing effect is ensured; the device is established on the basis that the width of the steel plate is the same at each position in the translation conveying process, but in practical application, the steel plate has errors due to processing, places with different widths can appear, or edges and corners or protrusions appear at certain positions of the side edge of the steel plate, but in the device, the position of the guide wheel is preset, and the position adjustment of the guide wheel is controlled by the screw rod and nut mechanism, so that the device cannot be self-adaptively adjusted in the processing process, when the protrusions or the edges and corners are touched, the guide wheel can be impacted, and then the brush roller which runs at a high speed can be impacted, and danger is caused.
