Embodiment

[0026] Embodiment: a manufacturing method of a micro-diameter aluminum tube, the manufacturing method is based on a circular insertion knife 1, a pressing mechanism 2, a push rod 3 and a micro-diameter aluminum tube 4;

[0027] The circular slot 1 is provided with several first wire slots 10 and several second wire slots 11 in parallel along its axial direction, and the first wire slots 10 extend from one end surface of the round slot 1 to the circular The middle part of the insertion knife 1 forms several first elastic blades 12, and the second wire passage groove 9 extends from the other end face of the circular insertion knife 1 to the middle part of the circular insertion knife 1 to form several second elastic blades 13. The slot 10 and the second wire slot 11 partially overlap along the circumferential direction. The first wire slot 10 is composed of a first front slot 101, a first rear slot 102 and a first bending slot 103. The first rear slot The wire slot 102 is locate...

Abstract

The invention discloses a manufacturing method for micro-aperture aluminum pipes. The manufacturing method is implemented on the basis of a round slotting tool, a compression mechanism, an ejection rod and a micro-aperture aluminum pipe. The round slotting tool is provided with first line through grooves and second line through grooves, each line through groove is formed by a first front line groove, a first rear line groove and a first bent line groove, the first rear line grooves are disposed on line extension sides of the first front line grooves, the first bending lines are connected with the corresponding first front line grooves, lateral blades are arranged on both sides of the first bent line grooves and second bent line grooves, the compression mechanism comprises a cylinder, a piston and a tapered cover, and the cylinder is hermetically and fixedly connected with the tapered cover. The manufacturing method includes: clamping the round slotting tool by a chuck of the compression mechanism; placing the round slotting tool in a through hole of an outer aluminum pipe sleeve after the round slotting tool is deformed in the first step; placing the ejection rod into the through hole of the outer aluminum pipe sleeve, and pushing the ejection rod to drive the deformed round slotting tool to move. The manufacturing method has the advantages that all protrusive points on the whole inner wall of the outer aluminum pipe sleeve can be removed at one time, bounce of a middle portion of the round slotting tool is greatly increased, overmuch scrapping is effectively prevented, and consistency in production performance is guaranteed.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a manufacturing method for micro-diameter aluminum tubes. Background technique [0002] In the prior art, the blade of the ordinary scalpel is wide and causes great damage to normal tissues, so it is not suitable for minimally invasive surgery. Minimally invasive surgery is welcomed by patients because of less trauma, less pain and faster recovery. However, due to the limitations of equipment and conditions, surgery has high requirements for doctors. [0003] After long-term processing, it is found that the defect rate of the outer aluminum tube sleeve of the micro-diameter aluminum tube has remained high, and most of the processed parts cannot meet the precision requirements. The main reason is that the extrusion material is poorly fed, and small bumps of 0.05MM~0.1MM often appear on the inner wall of the aluminum agent material. However, this phenomenon cannot be improved in ...
