Problems solved by technology

Because the bent sample tube is completely manual operation, the bending size and precision of the actual catheter sample obtained according to this sample tube are difficult to meet the numerical control bending conditions, and workers need to manually bend the actual catheter sample, which will greatly reduce the subsequent batch of catheters Production efficiency and manufacturing precision

Embodiment Construction

[0015] Because large-scale machinery requires many tubes, it is impossible to manufacture corresponding sample tube bending molds according to the shape of each tube, so the tube bending parameters should follow the set numerical control bending conditions. Generally, the numerical control bending conditions are set as follows: the center line of the actual tube is bent The radius R is an integral multiple of 0.5 times the actual outer diameter of the catheter D, and the minimum is 2D, for example, 2.5D, 3D, etc.

[0016] A kind of catheter real sample preparation method, such as Figure 4 As shown, the specific method is as follows:

[0017] 1) According to the assembly space and the size of the actual catheter sample 1, according to the numerical control bending conditions, select the sample tube bending mold 3 of the corresponding size; take the actual catheter sample 1 with an outer diameter of φ30mm as an example, select the bending radius as 3D, and use a φ6mm sample tub...

Abstract

The invention discloses a method for taking and manufacturing guide tube real samples. The method particularly includes 1), selecting a sample tube bending mold with a proper side according to the size of assembly space, the size of a guide tube real sample and numerical-control bending conditions; 2), forming a sample tube on the sample tube bending mold and enabling the geometric appearance of the sample tube to meet assembly requirements; 3), measuring the sample tube by a numerical-control measuring machine to acquire bent data of a center line of the sample tube; 4), inputting the bent data of the center line of the sample tube into a tube bending machine to carry out numerical-control production of the guide tube real sample. The method has the advantages that the production of the guide tube real sample enters the digital era by the aid of the method, the guide tube real sample taking and manufacturing speed is obviously increased, the guide tube real sample taking and manufacturing accuracy is obviously improved, and the follow-up guide tube production efficiency and the follow-up guide tube manufacturing precision are further guaranteed.

Description

technical field [0001] The invention relates to a method for taking a real sample of a catheter at the assembly site and realizing numerically controlled bending, in particular to a method for accurately controlling the shape and direction of the real sample of the catheter by using a sample tube bending mold so that it meets the conditions of numerically controlled bending method. Background technique [0002] Many complex machines, such as airplanes and aero-engines, etc., when assembling ducts, due to assembly position restrictions, tolerance accumulation and other reasons, the shape of many ducts needs to be determined on-site according to the surrounding assembly status. [0003] Taking the aircraft duct as an example, the traditional sampling process of the aircraft duct is as follows: figure 1 As shown, workers often use small-sized aluminum tubes such as φ6mm as the sample tube to obtain the shape direction of the required actual catheter sample, because the shape o...
