SU766703A1 - Expanding drum for tape - Google Patents

Description

one

The invention relates to the processing of metals by pressure and can be used in the processing of rolls of tape with a large range of internal diameters.5

A tape drum is known that contains a shaft mounted with the possibility of axial movement, a pyramid placed at the end of the shaft, and segment 10 spacers p. In contact with the edges of the pyramid. ,

The disadvantage of this drum is the limited opening range and, consequently, the limited range of rolls processed on it.

Also known is the expansion drum for the tape containing the mounted one. with the possibility of axial movement 20 of the shaft, made of a spiramid at the end, segmented spacers 2 mounted on the pyramid.

The disadvantage of this Zaban ba is also the limited range 25 of its opening. And, consequently, the limited range of rolls processed on it.

The purpose of the invention is the expansion of technological capabilities due to

increasing the range of rolls to be machined in internal diameter.

This goal is achieved by the fact that it is equipped with annular plates installed on the segment spacers, placed on annular plates with guides in contact with ring plates on surfaces located at equal angles to the two adjacent faces of the pyramid, and elastic elements connected to, ring pads.

In FIG. 1 shows the proposed drum, a longitudinal section; Figure 2 is the same, front view; in fig. 3 - section-, cut A-A in FIG. one; in fig. 4 — node I in FIG. 2; in fig. 5 is a section BB in FIG. four; in fig. 6 is a view B on the lock in FIG. four; in fig. 7 - node II in FIG. 5, the lock in the working position.

Claims (2)

The expansion drum, mainly for unwinding the tape from the roll 1, contains a shaft 2 mounted with the possibility of axial movement, one end of which is made in the form of pyramids 3 coaxial with it, and the other is equipped with a spline 4 and is mounted in a hollow shaft 5, which is mounted on bearings 6 in housing 7. At the edges of the pyramids, with keys 8, segment spacers 9 are secured, which with their shoulders enter the annular groove of the detachable collar 10, which is fixed against rotation and axial movement relative to the hollow shaft. Ring pads 11 are installed on the spacer spacers. Each two ring pads located adjacently are connected by direction 12 and 12 elastic elements 13, for example, springs that are mounted with the help of pipes 14 and nuts 15. In one guides 16 are fixedly fixed from the ring linings, and in another possibility of interacting with the guides there are fasteners 16 fixed by the strips 17. At the same time, on the surfaces of the guide and ring linings in contact with each other us in planes perpendicular to the shaft axis at equal angles with respect to two of the nearest thereto of the pyramid faces (FIG. 2). The expansion drum works as follows. Moving the shaft to the right squeezes the drum, while the annular lining is constantly pressed against the segment spacers with springs. Using the loading and unloading teleloaders (it is conventionally not shown in the drawings), the reel slides onto the drum and moves the shaft to the left to fix it. the drum is unclamped, the locking mechanism is rotated 90 ° and secured with straps. During subsequent compression of the drum, the guides rest against the retainers prevent further movement of the ring linings, while the segment spacers occupy a smaller diameter. Using the aforementioned carriage, the ring lining kit is removed from the drum, which is ready to work in a smaller diameter range. The proposed belt expansion drum allows the technological capabilities of the marking devices to be expanded. Claim tape contains a shaft mounted for axial movement, made with a pyramid at the end, mounted on the pyramid segment spacers, characterized in that, in order to expand technological capabilities by increasing the range of rolls to be machined according to the inner diameter, segmented spacers with annular overlays placed on annular overlays with guides in contact with annular overlays on surfaces nym at equal angles k m two adjacent faces of the pyramid, and the elastic members, binding ring laths.
