Embodiment Construction
[0014] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.
[0015] The anti-loosening mechanism of the flying shears blade includes bolts, nuts 3 and washers 2 connecting the blade 9 and the knife arm 10. The bolts are anti-loosening bolts 4, and the anti-loosening bolts include bolt heads 6, threaded sections 7 and the bolts connecting the two. Polished rod section 8, said polished rod section 8 is provided with two symmetrical anti-loosening planes along the axial direction, and knife arm 10 is provided with an installation long groove that can be inserted into the polished rod section. The size and shape are the same, and the installation slots on the two anti-loosening planes 5 and the knife arm 10 have a tolerance fit. The bolt head 6 is a 30-degree conical surface and cooperates with the 30-degree conical hole displacement type cone on the blade 9 . The bolt cannot be rotated during work, and the pro...

The invention belongs to the technical field of flying shear components of coil bar production lines, in particular to a loosening prevention mechanism of a flying shear blade. The problems that the traditional flying shear blade is easy to loosen in the use process to result in the short service life of the blade and influence the work ratio of the coil bar production line can be solved. The loosening prevention mechanism of the flying shear blade comprises a bolt for connecting a blade and a knife arm, a nut and a gasket, wherein the loosening prevention bolt comprises a bolt head, a thread section and a polish rod section connected with the bolt head and the thread section; the polish rod section is provided with two symmetrical loosening planes along the axial direction; the knife arm is provided with an installation long groove, into which the polish rod section can be inserted; the sizes and the shapes of the longitudinal section of the installation long groove are identical to those of the longitudinal section of the polish rod section; and a conical surface with the bolt head of 30 degrees is matched with a displacement-type cone of a 30-degree conical bore on the blade. The loosening prevention mechanism of the flying shear blade has the beneficial effects that the loosening problem of the flying shear blade during the work can be completely solved, the service life of the blade is prolonged, the work ratio of the production line is improved, and the cost for each ton of steels is reduced.
Description
technical field [0001] The invention belongs to the technical field of parts of flying shears in a wire and bar production line, and in particular relates to an anti-loosening mechanism for flying shears blades. Background technique [0002] Flying shears are all configured on the existing wire and bar production line, and the function of the flying shears is to cut off the head and tail of the rolled piece that affects smooth rolling or to carry out accidental breaking when an accident occurs. Therefore, flying shears play a very critical role in the production line. And one of the main working parts of the flying shear is the cutting edge. Whether the cutting edge is installed correctly, whether the anti-loosening design is reasonable, and whether the disassembly is convenient all directly affect the life of the knife, product quality and production rate. The most critical of these is the anti-loosening of the cutting edge. [0003] Such as figure 1 As shown, the cu...
