Axial micro adjusting method for side clearance of meshed cutter head of side crusher

Abstract

The invention discloses an axial micro adjusting method for the side clearance of a meshed cutter head of a side crusher. The side crusher comprises a first driving shaft, a second driving shaft, the meshed cutter head, a machine frame, a first synchronizing gear, a second synchronizing gear, a supporting bearing, a positioning bearing and a fixing nut, wherein the meshed cutter head comprises an upper cutter head, a side pad, an upper blade, a lower pad, an upper pressing plate, a bolt, a lower cutter head, a lower blade and a lower pressing plate; and a set of axial adjusting device is connected to the tail end of the first driving shaft and comprises a shaft hub, a pressing plate, a shaft hub sleeve, a guide screw rod, a frame body, a worm, a hand wheel, a worm gear case, a worm sleeve, a connecting plate and a fixing sleeve. The axial displacement amount of the first driving shaft is determined by a rotating range allowed by the hand wheel, and the final side clearance theta between the blade of the upper blade and the blade of the lower blade is given in the rotating range and is less than or equal to the allowed axial clearance, so that axial micro adjustment on the side clearance of the meshed cutter head of a side crusher is realized. The side crusher has the characteristics of simple structure and convenience in mounting.

Description

[0001] technical field [0002] The invention belongs to the technical field of machinery, in particular to an axial micro-adjustment method for the side clearance of an engaged cutterhead of an edge cutter used for edge trimming of non-ferrous metal plates and strips. [0003] Background technique [0004] Non-ferrous metal plates and strips are prone to edge cracking during processing. In order to prevent the expansion of the cracking edge phenomenon, it is necessary to cut off the cracked edge parts on both sides of the plate and strip to ensure the yield of the plate and strip. [0005] The meshing cutter head is one of the trimming tools configured on the drum edge crusher. figure 1 is a schematic diagram of the end face projection of the engaging cutterhead. [0006] combine figure 1 , the meshing cutter head mainly includes an upper cutter head 1, a side gasket 2, an upper blade 3, a lower gasket 4, an upper pressure plate 5, a bolt 6, a lower cutter head 7, a lowe...
