Internally-tangent type highly-efficient cutting device for glass tube

Abstract

The invention discloses an internally-tangent type highly-efficient cutting device for a glass tube. The internally-tangent type highly-efficient cutting device has a structure which comprises a device body, a liftable glass placement platform, glass tube clamp assemblies, a glass tube and a cutting unit, wherein the liftable glass placement platform is arranged on the device body; and a glass tube clamp assembly mechanically connected with the machine body is respectively arranged at two sides of the liftable glass placement platform. Compared with the prior art, the internally-tangent type highly-efficient cutting device provided by the invention has the following beneficial effects: a disc extends into the glass tube, and three cutting wheels synchronously extend outwards and rotate, sothe device can adapt to glass tubes with different calibers; the cutting wheels move from the inner wall of the glass tube to the outer wall of the glass tube for cutting the glass tube, so the device can prevent pressure on the glass tube from generation due to cutting from outside to inside, avoids problems like cracking of the glass tube, can guarantee the quality of the glass tube, can avoidpowder scraps from splashing outwards, and can collect the powder scraps generated in the cutting process and prevent the powder scraps from splashing on the basis of a triboelectrification principle.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to an in-cut high-efficiency cutting device for glass tubes. Background technique [0002] Glass tube is a kind of glass with sodium oxide, boron oxide and silicon dioxide as the basic components. It has excellent mechanical properties, thermal stability, water resistance, alkali resistance, acid resistance and other properties, and is widely used in chemical industry, Aerospace, military, family, hospital and other fields. [0003] The glass tube needs to be cut during processing. The existing cutting machine cuts the glass tube from the outer wall of the glass tube to the inner wall of the glass tube. Since the glass tube is a hollow structure, the cutting piece cuts from the outside to the inside. , has a certain pressure on the glass tube, and the hollow part of the glass tube has no support points, which may easily lead to problems such as cracks on both sides of the ...
