Abstract

The invention discloses a semi-automatic balloon tube pre-forming machine and a method. The semi-automatic balloon tube pre-forming machine comprises a bottom plate, a movable mechanism, a heating mechanism and a stretching mechanism. The movable mechanism, the heating mechanism and the stretching mechanism are arranged on the bottom plate; the movable mechanism is arranged in the middle of the bottom plate; the movable mechanism comprises a rear support frame and a front support frame; the heating mechanism comprises a heating block; the heating block is fixedly arranged at the lower end of the front side of the front support frame; a worktable is arranged under the heating block; the stretching mechanism comprises a clamping device and a stretching motor. The method for applying the semi-automatic balloon tube pre-forming machine includes a plurality of steps of energizing, resetting, self-running, turnover operation and the like. The semi-automatic balloon tube pre-forming machine and the method have the advantages that a plurality of balloon tubes can be synchronously operated, in other words, the multiple balloon tubes can be simultaneously formed by means of one-step processing, and accordingly the production efficiency can be obviously improved; the semi-automatic balloon tube pre-forming machine can be operated in a semi-automatic manner, accordingly, the hand labor intensity can be effectively relieved, and the labor cost can be saved; the positioning precision can be controlled by PLC (programmable logic controllers), and accordingly the quality of products can beaccurately controlled.

Description

Technical field

[0001] The invention relates to a preforming machine and method, in particular to a semi-automatic balloon tube preforming machine and method. Background technique

[0002] The balloon is a common medical device used to support the lesions in the vascular stenosis. The balloon is sent to the stenosis site through a guide wire, and the balloon is compressed to expand the stenosis, thereby making the blood vessel unobstructed. The balloon forming machine can blow a variety of different specifications of balloons, but before the balloon is blown, the balloon tube needs to be pre-treated, which technicians call "pre-forming". The use of the preforming process in the balloon production process is extremely important. The traditional pre-forming method is to manually hold the balloon tube with one hand, and hold the needle-nose pliers in the other hand to manually stretch one end of the balloon tube, and then heat the stretched part of a single balloon tube through it ...
