[0001] The present application relates to the field of medical catheter processing technology, and particularly relates to a medical catheter processing and forming device. BACKGROUND

[0002] In the medical field, medical catheters are widely used. Different types of medical catheters have different functions. For example, a trumpet-shaped port formed by flaring processing and a sharp-end-shaped port formed by necking processing each has its own unique application advantages, which makes the forming and processing technology of the end of the medical catheter particularly important.

[0003] In the past, in the processing of the end of a medical catheter, in order to realize flaring or necking processing, two different forming devices are generally used. For flaring processing, a specific flaring die is generally used to gradually expand the end of the catheter into a trumpet-shaped port by mechanical extrusion. For necking processing, a necking die is used to make the end of the catheter shrink into a sharp-end-shaped port by applying pressure. These two processing methods rely on different dies and equipment, and the equipment needs to be replaced and adjusted according to different processing requirements.

[0004] Because different forming devices are needed to complete flaring and necking processing respectively, when switching between the two processing methods in actual production, the corresponding equipment must be replaced, the operation process is complicated, and not only the time cost of processing is increased, but also the production efficiency is reduced.

[0071] In the embodiment, the second driving member 24 comprises two air outlet seats 25 and a guide rail 26, the two air outlet seats 25 are both fixed to the mounting seat 21, and the two air outlet seats 25 are separately arranged on the two sides of the first clamping block 22 and the second clamping block 23. Taking the air outlet seat 25 on the side of the first clamping block 22 away from the second clamping block 23 as an example for description: the inside of the air outlet seat 25 is provided with an air cavity 251, one end of the air cavity 251 penetrates through the upper wall of the air outlet seat 25, and the other end penetrates through the surface of the air outlet seat 25 close to the first clamping block 22, that is, the air cavity 251 is in an “L” shape.
