Description

Technical Field

[0001] The utility model belongs to the field of burr removal of casting blanks, in particular to an anti-collision type sawtooth scraper seat. Background Art

[0002] In continuous casting production, the continuous casting billet needs to be cut into fixed lengths by a flame cutting machine. During gas cutting, iron oxide burrs (commonly known as burrs) will be generated. These burrs must be removed by a deburring machine, otherwise it will affect the rolling quality, roller life, and heating furnace life. There are many forms of deburring machines, one of which is a serrated scraper deburring machine, such as: Patent application number: 200820015149.7, which discloses a serrated slab deburring machine.

[0003] In the prior art, a plurality of sets of sawtooth scraper seats are installed on the deburring machine. Figure 1 , Figure 2 , the serrated scraper seats are all installed on the crossbeam of the deburring machine, see Figure 3 The serrated scraper is connected to the scraper seat with bolts. The scraper seat is seated in the mounting hole on the upper part of the crossbeam of the deburring machine through the compression spring seat. The convex block of the convex scraper seat fastening sleeve cooperates with the groove at the tail end of the scraper seat. The upper end surface of the convex scraper seat fastening sleeve cooperates with the end surface of the fastening hole at the lower end of the crossbeam, thereby locking the scraper seat. At the same time, the compression spring is compressed to generate a preload. During the deburring process, the compression spring is further compressed to generate a deburring force. At this time, the fastening sleeve of the lug-type scraper seat is separated from the end face of the fastening hole at the lower end of the beam, and the lug of the fastening sleeve of the lug-type scraper seat will be separated from the groove, causing the serrated scraper to collide with the ingot and be damaged. In addition, after the serrated scraper completes the burr removal and separates from the ingot, the rebound of the compression spring will cause the fastening sleeve of the lug-type scraper seat to collide with the end face of the fastening hole at the lower end of the beam, causing the lug to break and be damaged, and the serrated scraper to collide with the ingot and be damaged. Thirdly, when installing or replacing the scraper seat, a special tool is required to compress the compression spring in order to complete the installation of the fastening sleeve of the lug-type scraper seat, which is time-consuming and labor-intensive.
