The invention provides a middle drum assembly of an assembly drum, the assembly drum and a middle drum block replacement method of the middle drum assembly. The middle drum assembly comprises: a drum shoulder; the middle drum block is provided with a mounting groove and a fixing hole; the first fastening piece is movably arranged in the drum shoulder in a penetrating mode and can move in the axial direction of the forming drum, the first fastening piece is provided with a step face, when the middle drum block is in butt joint with the drum shoulder in the radial direction of the forming drum, the installation groove is aligned with the first fastening piece, and the middle drum block extrudes the step face and enables a part of the first fastening piece to stretch into the installation groove; one part of the second fastening piece is arranged in the drum shoulder in a penetrating manner, after one part of the first fastening piece extends into the mounting groove, the fixing hole is aligned with the second fastening piece, the middle drum block is close to the drum shoulder in the axial direction of the forming drum, and the part, exposed out of the drum shoulder, of the second fastening piece extends into the fixing hole. The problem that time and labor are wasted when tooth-shaped blocks of a drum shoulder part are replaced in the prior art is solved.
Description
technical field [0001] The invention relates to the technical field of tire processing, in particular, to a middle drum assembly of a forming drum, a forming drum and a method for replacing a middle drum block of the middle drum assembly. Background technique [0002] The length of the toothed block of the shoulder part of the forming drum needs to be replaced with different sizes of toothed blocks according to different tire specifications. When it is necessary to remove the connecting screws, it takes a lot of time and affects the efficiency. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to provide a middle drum assembly of a forming drum, and a method for replacing the middle drum block of the forming drum and the middle drum assembly, so as to solve the problem of time-consuming and laborious replacement of the toothed block of the drum shoulder part in the prior art. [0004] In order to achieve the above object, according to one aspe...
