DETAILED DESCRIPTION

[0011] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings.

[0012] like Figure 1 The illustrated automatic riveting device for copper tubes features a guide rail 2 and a cylinder support 15 fixed to a base plate 1. A guide platform 3 engages with the guide rail 2 and can slide along it. A displacement cylinder 14 is fixed to the cylinder support 15, with its piston rod connected to the guide platform 3. Extension and contraction of the displacement cylinder 14 drives the guide platform 3 to slide along the guide rail 2. A fixing block 4 and a center seat 5 are fixed to the guide platform 3 and are used to secure the copper tube 6 and main valve body 7 to be riveted. A top plate 10 is secured to the base plate 1 via four support columns 8. A pressure cylinder 11 is fixed to the top plate 10, with its piston rod extending and contracting through a hole in the center of the top plate 10 and connected to a riveting head 9. This extension and contraction of the pressure cylinder 11 drives the riveting head 9 to provide pressure for riveting the copper tube 6. A controller 13, via a cylinder solenoid valve 12, controls the extension and contraction of the pressure cylinder 11 and displacement cylinder 14 when both power and air are supplied.

[0013] Combine Figure 1-4 The working principle of the automatic riveting device for copper tubes provided by the utility model is as follows: first, insert the copper tube 6 into the center seat 5; then put the main valve body 7 on it, paying attention to inserting the copper tube 6 into the corresponding hole of the main valve body 7 and making one end of the main valve body 7 lean against the fixed block 4; next, press the start button on the controller 13, at this time the device is started, and the action steps are: the piston rod of the displacement cylinder 14 retracts to drive the guide table 3 to align the riveting head 9 with the riveting part, the piston rod of the pressure cylinder 11 extends to drive the riveting head 9 to apply pressure to the riveting part to expand and deform one end of the copper tube 6 to complete the riveting, the piston rod of the pressure cylinder 11 retracts, the piston rod of the displacement cylinder 14 extends, and the device is reset; finally, take out the main valve body 7, at this time the copper tube 6 has been riveted to the main valve body 7.

[0014] The utility model is simple to operate and has high riveting efficiency. It has been used in production practice, with a significant improvement in product yield and good implementation effect.

[0015] In summary, in industrial applications, the automatic riveting device for copper tubes provided by the present invention can replace riveting heads and center seats of various specifications to meet the riveting requirements of metal tubes of different materials and diameters in product holes.
