Description

Scraper knife structure Technical Field The utility model relates to a shovel blade, in particular to a shovel blade structure, and belongs to the technical field of shovel blades. Background The automatic metal slice shovel is mainly used for forming fins for processing copper and aluminum metal materials, and is widely applied to industries such as aviation, aerospace, high-speed rail, photovoltaic, electronic computers, air conditioners, bath heaters and the like. And the structure of the shovel blade and the shovel blade seat is a core component thereof. When the fin forming processing of copper and aluminum metal materials is carried out, the position and the angle of the shovel blade are very important to be adjusted, and the fixing method of the shovel blade and the shovel blade seat is simple and easy to loosen. Disclosure of utility model The utility model aims at solving the defects of simple fixing method and easy loosening in the prior art of the structure of the shovel blade and the shovel blade seat, and provides the shovel blade structure which can achieve the purposes of simple installation, stable structure, difficult loosening, durability and stable shoveling and cutting of the shovel blade and the shovel blade seat. In order to achieve the aim, the technical scheme adopted by the utility model is that the scraper knife structure comprises a scraper knife seat and a scraper knife main body, wherein the scraper knife seat is polygonal column-shaped and vertically arranged and comprises an upper end face, a lower end face and a plurality of side vertical faces; The scraper knife main body further comprises a back knife, a scraper knife and a plurality of fixing bolts, wherein the back knife comprises an A surface, a B surface and a front end, the thickness of the back knife is h, the A surface is an inner side surface fixedly attached to the scraper knife, the B surface is an outer side surface assembled and attached to a scraper knife seat, and the A surface and the B surface of the back knife are parallel to each other; Because the A surface and the B surface of the back knife are parallel to each other, the installation direction of the shovel knife is adjusted through the installation direction of the shovel knife seat, and the shovel knife seat rotates clockwise or anticlockwise to adjust the included angle between the shovel knife and the processed strip profile; A clamping groove is formed in one side face of the scraper knife seat, the face B of the back knife is clamped in the clamping groove and is in tight fit connection, a plurality of screw through holes A are uniformly formed in the middle of the scraper knife in the vertical direction, a plurality of screw through holes B are formed in the position, corresponding to the scraper knife screw through holes A, of the back knife, a plurality of blind holes are formed in the clamping groove, corresponding to the back knife screw through holes B, and the scraper knife, the back knife and the scraper knife seat are fixedly screwed in the blind holes in a screwed mode through the screw through holes A and the screw through holes B through fixing bolts.
