专利汇可以提供Method and apparatus for shaping the ends of glass tube专利检索，专利查询，专利分析的服务。并且Glass tubes are transferred while being rotated by means of roller groups arranged in a plurality of rows. Intermediate between the ends of the transfer path, on both sides of the roller groups and in intermediate positions corresponding to the portions to be treated of the glass tube close to both ends thereof, there are correspondingly provided burners, a shaping rail for squeeze shaping the tube cooling pipes, a cutter burner and thin circular cutting plate for cutting the tube at the middle of the shaped portion and burners for smoothing the cut surfaces and for successively cooling those surfaces with gentle flames.，下面是Method and apparatus for shaping the ends of glass tube专利的具体信息内容。
1. A method for producing a shaped glass tube having squeezeshaped ends, which method comprises in combination: a. providing a tube blank somewhat longer than the required length of the shaped tube to be formed, b. rotating said blank about its axis and simultaneously bodily moving said rotating blank in a direction transverse to said axis, c. simultaneously softening areas of the so moving rotating blank lying adjacent to but spaced from the ends of the so moving rotating blank by heating said areas, said areas being spaced from each other by a distance corresponding to the length of the shaped glass tube to be formed, d. simultaneously applying squeezing pressure in the heated areas of the so moving rotating blank to reduce the tube diameter in said areas, e. simultaneously cutting through said moving rotating blank in said reduced diameter areas to separate the blank into a so moving rotating central tube portion of said required length and two freed end portions, f. removing said freed end portions, and g. simultaneously flaming the cut ends of said moving rotating central portion to effect mouth-burning thereof.
2. A method as claimed in claim 1, wherein in step (d) the reduced diameter areas produced in the so moving rotating tube are hardened by cooling, as a prelude to step (e).
3. A method as claimed in claim 2, wherein the moving rotating tube blank during steps (b), (c) and (d) is supported in four regions, two of which lie between and proximate to but spaced from the areas referred to in steps (c) and (d) and the other two of which lie outside of and proximate to but spaced from said areas, and wherein during steps (e), (f) and (g) the moving rotating central tube portion is supported at two regions proximate to but spaced from its cut ends.
4. Apparatus for continuously producing shaped glass tubes having squeeze-shaped ends from tube-blanks somewhat longer than the required length of the shaped tubes to be formed, said apparatus comprising: a. means for receiving and supporting said blanks in a parallel array in a horizontal plane and for simultaneously rotating the blanks about their longitudinal axes and bodily moving the same continuously along said plane in a downstream direction transverse to said axes, to a point of delivery thereof, b. heating means arranged along the paths traversed by the ends of the moving rotating blanks, and positioned for simultaneously softening areas of said moving rotating blanks spaced from the opposite ends thereof and separated by a distance corresponding to the length of the shaped glass tubes to be formed, c. squeezing means arranged along said paths downstream of said heating means for simultaneously applying squeezing pressure in the heated areas of the moving rotating blanks to reduce the tube diameters in said areas, d. cutting means arranged along said paths downstream of said squeezing means for simultaneously cutting through the moving rotating blanks in the two reduced diameter areAs thereof for separating each of the moving rotating blanks, one after the other, into a moving rotating central tube portion of said required length and two freed end portions, the apparatus along said paths at the downstream end of said cutting means providing for the removal of the freed end portions cut off thereby, and e. means for simultaneously mouth-burning the two cut ends of the so moving rotating central tube portions, comprising flaming means arranged along said paths downstream of said cutting means.
5. Apparatus as claimed in claim 4, further comprising: f. cooling means arranged along said paths between said squeezing means and said cutting means for hardening the reduced diameter areas of the rotating blanks moving to said cutting means.
6. Apparatus as claimed in claim 5, wherein the means (a) comprises conveying means arranged at each side of each of said paths in positions to support said blanks at both sides of each of said areas during the movement thereof downstream past said cutting means.
7. Apparatus as claimed in claim 6, wherein said conveying means are of the travelling roller type for concurrently moving and rotating said tubes, and wherein the conveying means arranged between said paths have a traverse which extends to said point of delivery, while the conveying means arranged outside said paths extend therealong only upstream of said cutting means.
