The first die 300 and the second die 400 present grooves that cannot be retracted directly after the rim is flared or expanded. The existing expanding machine needs a person to take down the rim after finishing the flaring or expanding of the rim, and the rim is large in mass, so that manual material taking is slow and extremely inconvenient, and potential safety hazards exist when a human body stretches into the expanding machine. As shown in fig. 8 and 9, the horizontal type expander further comprises an ejecting mechanism 700, wherein the ejecting mechanism 700 is connected to the frame 100, is positioned below the first mold 300 and the second mold 400, and can move upwards to support the processed rim.

After the first die 300 and the second die 400 finish flaring or expanding the rim, the liftout mechanism 700 moves upwards to jack up the rim, and the first die 300 and the second die 400 retract directly. The material ejecting mechanism 700 replaces manual material taking, the working efficiency is high, the physical consumption of operators is reduced, and potential safety hazards are eliminated.

As shown in fig. 8 and 9, the ejector mechanism 700 includes an ejector driving member 710, a height adjusting assembly 730, and a holder 720; the ejection driving piece 710 is mounted on the frame 100 and can move up and down; the height adjusting assembly 730 is mounted on the material ejecting driving member 710 and can extend and retract along the up-down direction; the material supporting seat 720 is connected to the height adjusting assembly 730 for supporting the processed rim.

The height adjusting assembly 730 can adjust the distance between the cradle 720 and the first and second molds 300 and 400. When the types or specifications of the first mold 300 and the second mold 400 are changed, the jacking mechanism 700 is adapted to the changed first mold 300 and second mold 400 by operating the height adjusting assembly 730, so that interference with the jacking mechanism 700 when the first mold 300 and the second mold 400 move towards each other is avoided, and the jacking seat 720 can jack up the rim after the driving piece moves upwards.

The ejector driver 710 powers the up and down movement of the holder 720, and fig. 8 and 9 show that the ejector driver 710 is a double-guide-rod cylinder. Of course, the material ejecting driving member 710 may also be a hydraulic cylinder, a linear motor, or the like.

The height adjustment assembly 730 is specifically constructed as follows. As shown in fig. 8 and 9, the height adjustment assembly 730 includes a first connection plate 731, a second connection plate 732, an ejection screw 733, and an ejection nut 734; the first connecting plate 731 is mounted on the ejection driving member 710; the lower end of the ejection screw 733 penetrates through the first connecting plate 731, two ejection nuts 734 are arranged on the ejection screw 733, and the two ejection nuts 734 are respectively abutted against two sides of the first connecting plate 731; the second connection plate 732 is connected to an upper end of the ejector screw 733, and the holder 720 is connected to the second connection plate 732.

When the height adjusting assembly 730 needs to be adjusted, the two jacking nuts 734 are rotated to make the two jacking nuts 734 away from the side surface of the first connecting plate 731, the distance between the second connecting plate 732 and the first connecting plate 731 is adjusted until the tray reaches a proper height, and the two jacking nuts 734 are rotated again to make the two jacking nuts 734 respectively abut against the two sides of the first connecting plate 731.

As shown in fig. 8, the holding tray includes two holding plates 721, and the two holding plates 721 are connected at an angle. When the material holding plate jacks up the rim, the rim is located between the two material holding plates 721, and the rim is prevented from rolling off the material holding plate.

Specifically, as shown in fig. 3, a mounting plate 131 is provided on the bed plate 130, and in the moving direction of the first mold 300 and the second mold 400, the mounting plate 131 is located between the first mold 300 and the second mold 400; as shown in fig. 8 and 9, the ejector mechanism 700 further includes a connecting assembly 740, the connecting assembly 740 includes a rib 741 and a connecting plate 742, the connecting plate 742 is disposed on the ejector driving member 710 and perpendicular to the movement direction of the ejector driving member 710, and the rib 741 is disposed between the ejector driving member 710 and the connecting plate 742 for enhancing the connection strength between the ejector driving member 710 and the connecting plate 742. The connection plate 742 is connected to the mounting plate 131 to mount the ejector mechanism 700 to the rack 100.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
