Abstract
The utility model relates to a burring cutter bar which comprises a cutter bar. A blade assembly part is arranged on the upper end portion of the cutter bar through a bolt, the lower portion of the cutter bar is sleeved in a cylinder, the lower end portion of the cutter bar is contacted with a piston, an upper gland is arranged on the cutter bar on the upper end portion of the cylinder, the piston and a piston rod connected with the piston are arranged in the cylinder, a spring is sleeved on the upper portion of the piston rod, and a lower gland is arranged on the lower portion of the piston rod. Heating is not needed, burring is directly carried out on billet steel under a hot state, energy sources are saved, producing efficiency is improved, and the burring cutter bar has the advantages of being simple in structure, long in service life, safe and reliable in operation and high in producing efficiency, is a tool for burring the surface of a bland steel plate, and is suitable for being used by steel plants.
Description
Technical field
The utility model belongs to steel plate and handles the specific purpose tool technical field, relates to a kind of each steel mill that is suitable for and is used for removing the burr of blank surface of steel plate and the deburring knife bar of oxide skin.
Background technology
At present, existing burring knife lever apparatus is to be formed by knife bar, cutter head, knife bar cover, stationary gland and spring assembly, in use, relies on the interior spring of knife bar and knife bar cover with the high effect of playing deburring and oxide skin to the blank surface of steel plate of cutter head bullet.But after said apparatus used a period of time, knife bar did not get up with regard to bullet, has seriously influenced the production of applying unit.Its reason is: the burr in the deburring process and oxide skin have fallen into and have caused knife bar stuck with the knife bar cover in the knife bar cover, and the coefficient of elasticity of the interior spring of knife bar and knife bar cover is limited in addition.It is unclean, irregular the product deburring often to occur, thereby causes the appearance of substandard product, and above problem has seriously influenced normally carrying out of producing.
The utility model content
In order to overcome the above-mentioned shortcoming of prior art, the utility model provide a kind of have simple and reasonable, handling safety is reliable, production efficiency is high, the deburring knife bar of long service life advantage.
The technical method that its technical problem that solves the utility model adopts is: a kind of deburring knife bar, comprise knife bar, the blade assembly parts are equipped with by bolt in upper end at knife bar, the bottom of knife bar is sleeved in the cylinder body, the bottom of knife bar contacts with piston, and the knife bar in the cylinder body upper end is provided with upper press cover, the piston rod that piston is housed in the cylinder body and links with piston, top at piston rod is set with spring, in the bottom of piston rod lower cover is housed.
Upper end at knife bar is provided with dust cover.
Piston seal is equipped with in contact position between piston and the cylinder body.
This special envelope and the O circle that seals is equipped with in the contact position of lower cover and cylinder body.
Bottom at piston rod is provided with spacing ring, and spacing ring is fixed on the piston rod by split pin.
The beneficial effects of the utility model are: no longer heating, steel billet is directly deburring under hot state, not only saved the energy, and improved production efficiency, have simple and reasonable, long service life, reliable, the advantage of high production efficiency of handling safety, be a kind of burr of blank surface of steel plate and specific purpose tool of oxide skin removed, be suitable for each steel mill and use.
