Elastic seal for slide surface of press having endless belt

专利摘要:
In a device forming a pressure cushion in a double belt press, the device including a pressure plate mounted in one support structure of the press, and a sealing member seated in a groove in the pressure plate to bear against the associated steel belt such that the sealing member, the steel belt and the surface of the plate surrounded by the groove together delimit a chamber arranged to contain a pressure medium to form the pressure cushion, the sealing member includes an elastically yieldable component extending around the entire path of the groove and arranged to be in sliding contact with the associated belt, and two wall components of rigid material each disposed along a respective lateral surface of the elastically yieldable component which extends transverse to the surface of the support plate and each located along at least one groove portion extending generally in the direction of belt advance, the pressure plate includes supporting elements defining at least part of the groove portions extending generally in the direction of belt advance and provided with a series of teeth projecting from the side thereof defining such part of the groove portions and spaced apart along the groove portions, and the sealing member has a toothed configuration along the sides thereof facing the supporting elements and formed to mesh with the teeth of the supporting elements for transmitting friction forces imposed on the sealing member by the associated belt to the pressure plate.

专利说明:

in fig. 6 is a sectional view BB in FIG. five; Fig.7 - section GGD of Figs. four.
The elastic seal contains a closed seal 1 installed in the slot 2 of each press unit 3 mounted above one of the branches of the endless belts 4 mounted on the drums 5 and installed with a clearance to pass the workpiece 6.
Seal 1 consists of three elements — an outer metal shell 7 with teeth 8, an inner metal shell 9 with teeth Yu, and an elastic cord 11 placed between the shells 7 and 9. In the hollows
the teeth 8 and 10 are the protrusions of the teeth 12 of the mounting bars 13 and 14.
The compactor is pressed against the endless band 4 by fastening strips using springs 15 and 16 respectively.
Elastic seal works as follows.
The preform 6 is pressed between the branches of the endless belt 4, which is subjected to pressure in the pressing unit 3. At the same time, the working medium is held in the pressing unit by the compactor 1, and the teeth made on it reduce the friction surface and fix the compactor from deformation when the workpiece is moved, 6.
The economic effect of implementing the present invention is achieved by increasing the reliability and durability of the seal.
