A capillary tube head-shrinking machine sequentially comprises a driving device, a transmission device and a head-shrinking device from left to right, wherein the head-shrinking device sequentially comprises a shell, a rolling shaft and a head-shrinking mold from outside to inside; a cylindrical through hole is formed in the center of the head-shrinking mold; the diameter of the right side surface of the through hole is the same with that of a pipe; the diameter of the through hole is gradually reduced towards the left until the diameter of the through hole is the same with the standard size of the pipe in head-shrinking operation; capillary tube head-shrinking operation is performed on the right side surface of the head-shrinking mold; a plurality of positioning holes are formed in the right side surface of the head-shrinking mold; and a head-shrinking operation hole is positioned in the center of the right side surface of the head-shrinking mold. The capillary tube head-shrinking machine is a small head-shrinking machine; the head-shrinking machine is simplified into a driving portion, a transmission portion and a head-shrinking portion; by using the head-shrinking portion, the rolling shaft drives the head-shrinking mold to rotate at high speed, so that a head-shrinking procedure is finished; a rotating shaft is driven by the motor; the power of the head-shrinking machine is reduced to 0.75kW; the energy consumption is quite low; and the work efficiency is improved.
Description
technical field [0001] The invention relates to the field of precision metal tube processing, in particular to a capillary shrinking machine. Background technique [0002] Tube necking is a forming process that reduces the diameter of the end of the tube blank. The tube blank enters the deformation zone under the action of axial force, and produces tangential shrinkage plastic deformation in the deformation zone, then enters the stable zone, and finally forms a reduced end diameter. At present, most of the common head shrinking machines in China are too large in size, noisy and overpowering. Contents of the invention [0003] The invention aims to provide a capillary shrinking machine. [0004] In order to achieve the above-mentioned technical purpose, the present invention adopts the following technical scheme, a capillary shrinking machine, which is a driving device, a transmission device and a shrinking device from left to right, and is characterized in that the trans...
