[0024] At present, some medical instruments need to install lead pipes inside to isolate external signals. In order to ensure the integrity of signal shielding, the lead pipe needs to fit the instrument shell completely, which requires flanging of the lead pipe and some windows of the instrument. However, the thickness of the lead pipe and the window position are inconsistent, and the window specifications are small, so the conventional window lead plate stretching and flanging process cannot be achieved. In addition, the small specifications of the tube body and the narrow space are not suitable for manual pressure application.

[0025] In order to solve the above problems, the present embodiment discloses a flanging tool for a narrow window 301 of a lead pipe 302, comprising a base 100, a flanging assembly 200, a pressure rod 103 and a support platform 104, wherein the base 100 and the support platform 104 are spaced apart; the base 100 is provided with a positioning groove 101 for placing the product, one end of the pressure rod 103 is used to abut against the base 100, the flanging assembly 200 is installed at the other end of the pressure rod 103 and is opposite to the positioning groove 101, and the positioning groove 101 is provided with a groove 102 adapted to the shape of the flanging assembly 200.

[0026] Specifically, a flanging tool for a narrow window 301 of a lead pipe 302 in this embodiment is provided with a base 100, a flanging assembly 200, a pressure rod 103 and a support platform 104. When in use, the device to be processed and the lead pipe 302 are placed on the base 100, and the positioning groove 101 on the base 100 cooperates with the window 301 of the device; then external force is applied to the pressure rod 103, and under the action of the support platform 104, the flanging assembly 200 is squeezed into the position of the lead pipe 302 corresponding to the window 301 through the lever principle, and finally the flanging assembly 200 is pressed into the groove 102 to complete the flanging, so as to meet the processing requirements of the small window 301 of the lead pipe 302 of the medical instrument 300.

[0027] In addition, the height of the support platform 104 is greater than the height of the base 100 , which can improve the utilization rate of the lever principle and increase the downward pressure of the pressure rod 103 .

[0028] Specifically, the flange assembly 200 includes a bottom 201 and a pressure head 202 connected in sequence from top to bottom, an arc-shaped pressure surface 206 is provided between the bottom 201 and the pressure head 202, and the upper end surface of the bottom plate is connected to the other end of the pressure rod 103. In this embodiment, the bottom 201 is responsible for connecting with the pressure rod 103; since the position of the lead pipe 302 and the window 301 will be opened in advance, the pressure head 202 is responsible for opening the small opening of the lead pipe 302, and then the arc-shaped pressure surface 206 is used to flange the lead pipe 302 along the side wall of the window 301.

[0029] Furthermore, the lower end of the pressing head 202 is provided with a first inclined surface 203; the lower end of the pressing head 202 is also connected to a cylindrical expansion piece 204, and the lower end of the expansion piece 204 is provided with a second inclined surface 205. By providing the first inclined surface 203, the expansion piece 204 and the second inclined surface 205, the efficiency of flanging can be effectively improved.

[0030] Specifically, the bottom 201 , the pressing head 202 and the expanding piece 204 of the present embodiment are integrally formed, which can improve the service life of the flanging assembly 200 .

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
