A kind of carcass drum flexible sleeve opening method

Abstract

The invention relates to a method for opening a hole for a flexible sleeve of a carcass drum, which is implemented by a device for opening a hole for a flexible sleeve of a carcass drum. The device includes a main shaft, a support plate, a drive assembly and an expansion connection assembly. In order that the center of the circle is arranged around the main shaft in a circular shape, any two supporting plates opposite to each other with the main shaft as the center are provided with a number of positioning holes along the axis of the main shaft, and the expansion connecting assembly is connected between the supporting plate and the main shaft. During this time, the expansion connection assembly can drive the support plate to expand relative to the main shaft under the action of the drive assembly. The hole-opening method based on the device is to expand the flexible sleeve to the extent that it fits with the carcass drum before punching, and then perform the hole-opening operation, which can avoid the dislocation deformation of the suction cup hole after the flexible sleeve is sleeved on the drum body. At the same time, a positioning hole is opened on the support plate, which can facilitate the subsequent hole opening operation and improve the operation efficiency.

Description

technical field [0001] The invention belongs to the technical field of flexible sleeve opening, in particular to a method for opening a flexible sleeve of a carcass drum. Background technique [0002] At present, there is a large demand for carcass drums with flexible sleeves in the market. Before the flexible sleeves are installed on the drum body, a suction cup hole needs to be made in advance to facilitate the later installation of the suction cup device. However, the diameter of the flexible sleeve will change before and after installation. The position of the suction cup holes on the flexible sleeve may be shifted, and the size and shape may also be changed, so that the suction cup device cannot be mounted on the drum body. SUMMARY OF THE INVENTION [0003] The present invention solves its technical problem by adopting the following technical solutions to realize: [0004] A carcass drum flexible sleeve opening method is implemented by a carcass drum flexible sleeve ...
