Embodiment Construction
[0016] The present invention will be further described below in conjunction with accompanying drawing and embodiment:
[0017] figure 1 It is a structural schematic diagram of the nozzle closing tooling of the present invention, please refer to figure 1 , a nozzle closing tool, which includes: a pipeline 1, the pipeline 1 is provided with internal threads, and two head blocks 2 are threadedly installed at both ends of the pipeline 1, and the head blocks 2 include: two close-fitting Huff block 3, a conical surface 4 connected to a tube hole 5 is opened in the part where the two Huff blocks 3 are close to each other, and the transition tube that needs to be sealed is placed in the pipeline 1, and the transition tube is placed between the two head blocks 2 During this period, the temperature measuring element passes through the tube hole 5; the two head blocks 2 are screwed tightly, and the tapered surface 4 squeezes the transition tube, so that the transition tube and the tempe...

The invention discloses a pipe orifice necking tool used in the necking process before laser welding of long temperature measuring elements and transition pipes, and belongs to the technical field of pipe orifice necking. The pipe orifice necking tool comprises a pipeline, wherein an inner thread is arranged inside the pipeline, and two end enclosure blocks are installed at the two ends inside the pipeline in a threaded mode. Each end enclosure block comprises two closely-attached Hough blocks, and a conical surface is communicated with one pipe hole formed in the closely attached part of the two Hough blocks. The pipe orifice necking tool solves the problem that the prior art lacks a necking tool which is used by the long temperature measuring elements conveniently and is good in sealing effect. The rapid necking tool can effectively enable the interval shaft hole fit to be tight shaft hole fit, the necking is even, the necked part can well meet the laser welding requirement, and the pipe orifice necking tool can also be used for mechanically riveting the transition pipes and does not damage the temperature measuring elements.
Description
technical field [0001] The invention relates to a nozzle closing technology, in particular to a nozzle closing tooling used in the process of closing a long temperature measuring element and a transition tube before laser welding. Background technique [0002] Quick closing tooling has a wide range of applications in the industry. Due to the requirements of different industrial conditions, there is often a transition tube connected by laser welding in the middle of the tens of meters long temperature measuring element to meet the requirements of the working conditions. When the length of the temperature measuring element is longer, the straightness of the temperature measuring element decreases significantly. In order for the transition tube to quickly pass through the middle of the longer temperature measuring element, the hole diameter of the transition tube can only be enlarged, while the laser welding of the transition tube and the temperature measuring element must be c...
