Description

Cold rolling mill with right angle saddle Technical Field The application relates to the technical field of cold rolling mills, in particular to a cold rolling mill with a right-angle saddle. Background The cold rolling mill is a core device for precisely rolling metal plates and strips, and is widely applied in the modern industry. With the improvement of the product quality requirements and the pressure of cost reduction and efficiency enhancement of downstream industries, cold rolling mills are developing towards high precision, high efficiency, modularization and easy maintenance. The roller bearing is used as a key bearing part of a cold rolling mill roller system, and the installation mode and the fixing stability of the roller bearing directly influence the rolling precision and the equipment operation rate. At present, bearing saddles in a roller box of a cold rolling mill are directly fixed on a base in a bolt connection or key connection mode, but the nature of the bearing saddles is single-point or single-sided constraint no matter the bearing saddles are in bolt connection or key connection. When bearing complex rolling force (including radial force, axial impact and overturning moment), the saddle is easy to micro-motion, twist or shake, and rigid support required by long-term stable operation of the bearing is difficult to ensure, so that the precision of rolled pieces is influenced, and the saddle is to be improved. Disclosure of Invention In order to solve the technical problems, the application provides a cold rolling mill with a right-angle saddle. The application provides a cold rolling mill with a right-angle saddle, which adopts the following technical scheme: the cold rolling mill with the right-angle saddle comprises an equipment assembly, an upper roller box and a lower roller box, wherein the upper roller box and the lower roller box are arranged on the equipment assembly, the equipment assembly is provided with a mounting groove, and the upper roller box and the lower roller box are both arranged in the mounting groove; The base is provided with a plugging groove, the mounting parts are in plugging fit along the extending direction of the plugging groove, two ends of the outer wall of the mounting part are connected with the outer wall of the rotating connecting part and are inwards recessed to form a bayonet, and the inner wall of the plugging groove is provided with two clamping parts which are matched with the bayonet. By adopting the technical scheme, the mounting part of the saddle is inserted into the two clamping parts in the inserting groove along the extending direction of the inserting groove to be mutually matched with the bayonets at the two ends of the saddle, so that two-point locking is formed, the mounting part can be stably mounted in the inserting groove, and the trends of shaking, twisting and the like of the saddle in the inserting groove are reduced. The assembly of bearing can be accomplished through the mode of pull, and this mounting means is comparatively convenient, has improved installation effectiveness, is convenient for follow-up dismantlement maintenance to bearing and relative part simultaneously. Optionally, two adjacent surfaces of the saddle are set as limiting surfaces, the joint of one end, away from each other, of the two limiting surfaces and the outer wall of the rotary connecting part forms a bayonet, and the two limiting surfaces are used for being matched with the inner wall of the inserting groove.
