Detailed Description

The following description of a preferred embodiment of the present invention will be made in conjunction with the accompanying drawings. However, the scope of the present invention is not limited to the following embodiments, and all simple equivalent changes and modifications made by the claims and the contents of the specification are still included in the scope of the present invention.

Referring to fig. 1-4, in order to provide the utility model with an X-ray bulb tube filament shaping device, the device comprises a rack 1, a horizontal working table 2 is arranged on the rack, a base 3 is arranged on the working table, a bell jar 4 which can be sealed with the base is arranged on the base, and the bell jar is fixed on a lifting bracket 5; the rack is provided with a lifting device 6, an electrical device 7 and a control operation panel 8, and the lifting device can drive the lifting support to move up and down; the base is provided with a positioning clamp 9 for fixing a cathode part of a filament to be shaped and a plurality of pairs of binding posts 15, the plurality of pairs of binding posts are respectively communicated with the electric device to realize multi-station operation, and the control operation panel controls the actions of the electric device and the lifting device; the rack is also provided with an air inlet 10 which is communicated into the bell jar through an air inlet pipeline 11, the bell jar is also internally provided with an air outlet pipeline 12, and an air outlet 13 of the air outlet pipeline is positioned outside the bell jar; and a protective gas delivery device communicated to the gas inlet.

Wherein, a sealing ring 14 used for being connected with the base in a sealing way is fixed at the bottom of the bell jar, and the lifting device is a hydraulic lifting device.

The X-ray bulb tube filament shaping device is mainly used for filament shaping, and the using process is as follows:

firstly, starting a hydraulic lifting device to drive a bell jar to rise, fixing a cathode part provided with a pending filament on a positioning fixture, and electrically connecting two ends of the filament to binding posts of a pair of bases respectively; then the lifting device drives the bell cover to descend, and the bell cover sealing cover is arranged on the base.

Then, the protective gas delivery device is activated to exhaust the air in the bell jar to prevent the filament from being oxidized when it is shaped.

Then, the electrical device is controlled by the control operation panel to shape the filament by the current (refer to fig. 3-4, which are schematic diagrams before and after the filament is shaped). The design is accomplished, exhausts through the gas vent and discharges protective gas, drives the bell jar through elevating gear once more and rises, takes off the part after the design, changes the filament part that next batch needs the design, so realizes processing in batches.

When the device is shaped to the filament, the filament is internally provided with a large current, so that the filament is deformed at high temperature to release stress generated during assembly, and the deformation can be corrected subsequently to restore the natural form, so that the filament is assembled into the bulb tube.

In the subsequent bulb operation, because the filament stress is released, the filament deformation amount is not obvious, and therefore, the focus of the bulb cannot be bent, and the image quality is not deteriorated. The Chinese national standard, IEC standard, CT whole factory and hospital have very strict requirements on the focus shape and image quality of the bulb tube. Therefore, the application of the filament shaping technology in the manufacturing process can greatly reduce the bulb tube scrap loss caused by the focus deformation, improve the product yield and save the manufacturing cost.

In addition, the device uses protective gas to discharge the air in the bell jar, and the protective gas can avoid the oxidation of the filament in the shaping process, and is also favorable for the cooling of the filament and the improvement of the production efficiency.

Therefore, the device is simple in structure, does not need a high-vacuum system, saves more energy, and enables the components to be cooled more quickly in a heat convection mode, so that the production efficiency is improved; the shape of the bulb lamp filament is shaped by the system and then is corrected, so that the shape and the size of the working focus of the bulb can be completely ensured to meet the requirement of accurate diagnosis; product scrapping caused by the shape and the size of the focus is avoided, the yield is improved, and the manufacturing cost is reduced.
