Description

Technical Field

[0001] The utility model belongs to the technical field of production of asbestos-free gaskets, in particular to a positioning mechanism used for production of asbestos-free sealing gaskets. Background Art

[0002] Asbestos-free gaskets are sealing products of various shapes made of asbestos-free sealing materials (such as aramid fiber, high-temperature resistant synthetic mineral fiber, oil-resistant rubber, etc.) by rolling or stamping and shearing with various tools according to various specific working conditions.

[0003] For example, the patent with patent number CN217317720U discloses a rapid positioning mechanism for the production of asbestos-free gaskets, which is provided with a fixed plate, a slide groove, a slider, a first pressure roller, a cross plate, a second pressure roller, a movable plate, a spring, a fixed shaft, a lifting plate, a side plate and a cylinder. When the cylinder drives the lifting plate to move downward, the lifting plate drives the movable plate to move, and the movable plate will move downward along the slide groove, and at the same time drive the first pressure roller and the second pressure roller to move downward. After the first pressure roller and the second pressure roller are moved down and positioned, they will also slide to both sides along the slide groove, so as to facilitate the pressing of the gasket and smoothing and wrinkle prevention on both sides at the same time. The scheme has a simple structure and a novel design, is convenient for quickly pressing and positioning the gasket, and is also smoothed and wrinkle-proofed at the same time to avoid wrinkling and indentation of the gasket after positioning, which is beneficial to the positioning quality of the gasket.

[0004] In the current prior art, after the asbestos-free gasket is positioned and fixed, a punching machine is required to punch and shear the asbestos-free gasket according to the design shape of the drawing. The above patent uses two first pressing rollers and a second pressing roller to position and fix the asbestos-free gasket, but there is also a problem that the first pressing roller and the second pressing roller occupy a large area of ​​the asbestos-free gasket, making it impossible for the punching machine to punch and shear the area where the first pressing roller and the second pressing roller are positioned and fixed, resulting in a large amount of waste of asbestos-free gaskets.

[0005] Therefore, in view of the above problems, a positioning mechanism for producing asbestos-free sealing gaskets is proposed. Utility Model Content
