Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0020] Such as image 3 , Shown in 4, the combination knife seat of the round billet derusting and peeling of the steel mill of the present invention comprises a knife rest body 1, a small knife seat 2, and a wedge fine-tuning mechanism.
[0021] The small knife seat 2 is installed on the front end of the knife rest body 1 and fixed with the small knife seat locking screw 3 to form a detachable connection mode. Coating cutter 10 is housed on the 2 heads of small knife holder. In this way, when the small knife seat 2 which is easily worn by chips wears to a certain extent, only the small knife seat 2 needs to be replaced without replacing the knife holder, which reduces the production cost.
[0022] An inclined wedge fine-tuning mechanism is provided between the small knife seat 2 and the tool rest body 1, wherein the inclined wedge 5 is placed between...

The invention relates to a combined tool holder for the rust removal and peeling of round billets manufactured by steel mills. The combined tool holder comprises a tool rest body and a small tool holder, wherein the small tool holder is arranged at the front end of the tool rest body, the small tool holder is fixed at the tool rest body by using lock screws for the small tool holder so as to form a detachable connection between the small tool holder and the tool rest body. A tapered-wedge fine-adjusting mechanism is arranged between the small tool holder and the tool rest body, a tapered wedge is arranged between the rear end face of the small tool holder and the step end face of the tool rest body, the middle part of the tapered wedge is connected with a tapered-wedge adjusting bolt, the front end of the tapered-wedge adjusting bolt is fixedly connected with the tapered wedge by a positioning platform and a fine pitch thread arranged on the tapered-wedge adjusting bolt, the rear end of the tapered-wedge adjusting bolt is in threaded connection with the tool rest body and fixedly locked by a locknut, and a tapered-wedge guide sliding key is arranged between the rear end face of the tapered wedge and the step end face of the tool rest body. The combined tool holder provided by the invention has the advantages that because the position of a tool is finely adjusted by using the tapered wedge so as to compensate the wear or manufacturing error of the tool, thereby ensuring the machining accuracy of the tool; and because the tool holder provided by the invention is a combined tool holder, when the combined tool holder suffers from excessive wear, only the small tool holder is required to be replaced, thereby saving the production cost; and the combined tool holder is simple in structure, easy to process and manufacture, and convenient to install and maintain.
Description
technical field [0001] The invention relates to a combined knife seat for mechanical cutting, in particular to a combined knife seat for derusting and peeling round steel billets in steel mills. Background technique [0002] Cutter discs are widely used in peeling machines for round steel billets in iron and steel enterprises. During production, the cutting tool rotates with the cutter head at high speed, and the axis of the round billet is fed in a straight line, thereby peeling off the rust layer of the round billet. [0003] At present, round steel billet derusting and peeling machines in iron and steel enterprises adopt a general integral knife seat structure, and the knife seats are evenly distributed on the derusting cutter head, such as figure 1 , as shown in 2, when the diameter of the production round billet changes, the position of the tool seat must be reset. According to the research on the production site, when adjusting, it is necessary to remove the cutter h...
