Problems solved by technology

[0003] At present, there is no relevant test method for the bending life of the core head of the spherical core rod. As a result, the service life of the spherical core rod accessories of various manufacturers is uneven during use. Frequent replacement of the core head requires re-adjustment, which seriously affects production. Efficiency and U-tube bending quality, so it is necessary to establish a bending life simulation test device and method for the core head of the spherical core rod

Embodiment Construction

[0033] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0034] see figure 1 , the invention provides a detection device for a spherical core rod, comprising an air source, a support 1, a cylinder 2 and a punch 3; the air source is connected to the cylinder 2; the spherical core rod 4 is installed on the support 1; the punch 3 Fixed on the cylinder 2; the punch 3 moves under the drive of the cylinder 2 and impacts the spherical core rod 4. When the number of impacts reaches the preset number, the punch 3 stops moving.

[0035] This embodiment provides a detection device for a spherical core rod, which mainly uses a cylinder to drive a punch to impact the core head of the spherical core rod to simulate the actual use state of the spherical core rod. ...

Abstract

The invention provides a detection device and method of a spherical core rod. The detection device comprises an air source, a support, an air cylinder and a puncher pin. The air source is connected with the air cylinder. The spherical core rod is arranged on the support. The puncher pin is fixed to the air cylinder. The puncher pin is driven by the air cylinder to move and impact the spherical core rod, and when the impact frequency reaches preset frequency, the puncher pin stops moving. The detection device of the spherical core rod is simple in structure and convenient to use, the service life and flexibility of the spherical core rod can be detected, the performance of the spherical core rod can be evaluated accurately, and the detection quality can be improved. Meanwhile, the quality of a U-type pipe is improved, the quality problem caused by the spherical core rod can be reduced, the time spent in machine changing, machine debugging and other procedures due to the quality of the spherical core rod is shortened, and work efficiency is improved.

Description

technical field [0001] The invention relates to the detection field, in particular to a detection device and method for detecting an air-conditioning fitting-spherical core rod. Background technique [0002] A large number of bent U-shaped tubes are used in the manufacture of air conditioners, and the bending quality of the U-shaped tubes is not only related to the tube bending machine, but also has a lot to do with its bending accessories - the spherical core rod. As a consumable part, the spherical core rod has a very important bending life and flexibility. [0003] At present, there is no relevant test method for the bending life of the core head of the spherical core rod. As a result, the service life of the spherical core rod accessories of various manufacturers is uneven during use. Frequent replacement of the core head requires re-adjustment, which seriously affects production. Efficiency and U-tube bending quality, so it is necessary to establish a bending life simu...
