A small catheter tip machine

Abstract

The invention provides a small guide pipe sharp head machine. An equipment body comprises a machine shell. The machine shell is internally provided with a main shaft. The end, stretching into the machine shell, of the main shaft drives a forming assembly to rotate, and the end, exposed out of the machine shell, of the main shaft is provided with a drive wheel. The forming assembly comprises a retainer, a forming die and a plurality of collision blocks. The retainer is arranged around the inner wall of the machine shell, and a plurality of roll pins are arranged along the retainer in the circumference direction. The forming die is composed of a plurality of sections of die bodies, and forming cavities are formed in the sides, towards a feeding port, of the forming die through the die bodies. The collision blocks are arranged in limiting through grooves of the main shaft in a sliding manner in the radial direction. The small guide pipe sharp head machine is simple in structure, reasonable in design and good in universality. In the small guide pipe sharp head machining process, running is stable and reliable, self-adaptation to the guide pipe end structure can be achieved, the machining efficiency is improved, and the defect that in the prior art, a small guide pipe is prone to being clamped in a die is overcome.

Description

technical field [0001] The invention belongs to the technical field of advanced small catheter processing equipment, and in particular relates to a small catheter tip machine. Background technique [0002] With the widespread use of tunnels, the amount of advanced small catheters is increasing, and the advanced small catheters need to be drilled and tapered. In the existing tip grinding equipment for advanced small catheters, induction heating is often required. After heating, manual grinding or cutting on a machine tool is very low in processing efficiency. At the same time, if cutting is used, there will be a lot of broken Chips, the tool is easy to wear when heated, after the tool is worn, it is difficult to guarantee the processing quality, and it is difficult to guarantee the quality of the finished product. As a result, in the prior art, the tapering process takes a long time, and it is easy to cause the tip and the tube body to be out of center, resulting in an unsat...

Problems solved by technology

In the existing tip grinding equipment for advanced small catheters, induction heating is often required. After heating, manual grinding or cutting on a machine tool is very low in processing efficiency. At the same time, if cutting is used, there will be a lot of broken Chips, the tool is easy to wear when heated, after the tool is worn, it is difficult to guarantee the processing quality, and it is difficult to guarantee the quality of the finished product

This leads to the fact that in the prior art, the tapering process takes a long time, and it is easy to cause the tip and the tube body to be out of center, resulting in unsatisfactory processing effect.

This requires the design of equipment specially used for the processing of small catheter tips. Although there are devices on the market that use perforations in the processing disc to process small catheter tips, the perforation of the processing disc is a fixed structure. After the small catheter is inserted, it is easy to get stuck, there is a great hidden danger of production accidents, and the processing quality cannot be reliably guaranteed
