Description

Technical Field

[0001] The invention relates to a tube shrinking device, in particular to an automatic positioning tube shrinking device, belonging to the technical field of tube processing. Background Art

[0002] Metal pipe, also known as iron pipe, is made of pipe material and is used to connect pipes. During the processing, one end of the metal pipe is reduced to facilitate the connection of the metal pipe to another metal pipe in the pipeline. The catheter can be inserted tightly and positioned with good sealing. It is now widely used. Sometimes, in order to improve the use effect and service life, iron alloys are often used to support the pipeline, and then the pipe is reduced. When reducing the pipe, a reduction device is needed to press and shrink the end of the metal pipe.

[0003] As disclosed in the publication number CN212917327U, a tube shrinking device for high-precision seamless tubes relates to the technical field of steel tube production equipment. The existing steel tube shrinking equipment has a complex structure and occupies a large area. Operators need to use a large force when using it to ensure the processing size of the tube fittings, which easily leads to poor shrinking accuracy and unstable product production quality. The device includes a frame, a clamping device, a tube shrinking device, and a supporting assembly arranged on the frame, wherein: the clamping device is fixedly arranged at the center of the frame, the tube shrinking device includes two groups, the two groups of tube shrinking devices are symmetrically arranged on both sides of the clamping device, and the supporting assembly is arranged between the tube shrinking device and the clamping device for supporting the tube fittings to be processed; a slide is provided on the frame, a fixed seat is provided at the bottom of the tube shrinking device, and a slide groove cooperating with the slide is provided on the fixed seat; scale lines are provided on the side walls of the frame along the length direction of the tube fittings to be processed. The technical solution has high tube shrinking accuracy, stable product quality, and high production efficiency.

[0004] Another example is the publication number CN102581155A, which discloses a tube shrinking device comprising: a frame, several material dragging racks, and a first clamping head, a second clamping head, a third clamping head, a first tube shrinking mechanism, and a second tube shrinking mechanism mounted on the frame. The first clamping head, the second clamping head, and the third clamping head each comprise a pair of clamping dies and a clamping oil cylinder for driving the pair of clamping dies to clamp the tube fitting. The first tube shrinking mechanism and the second tube shrinking mechanism each comprise a tube shrinking die and a driving oil cylinder for driving the tube shrinking die to move. A first positioning device is provided on one side of the first clamping head, a second positioning device is provided on one side of the second clamping head, and a third positioning device is provided on one side of the third clamping head. The tube shrinking device of the present invention has a simple structure and can directly connect and fix three metal tube fittings without welding, thereby improving production efficiency.

[0005] However, during use, the positioning effect is poor. When shrinking the tube, it is easy for the metal tube to be unable to be inserted into the interior of the tube shrinking die head for tube shrinking processing. When loading and unloading, workers are required to place the metal tube in the corresponding position, which is cumbersome. In addition, the metal tube is generally heavy, and repeated picking operations are labor-intensive and inconvenient to use. When manually picking up, not only is there a risk of clamping operation, but it also greatly affects the processing efficiency, making it inconvenient to use. Summary of the Invention
