[0018] Embodiment 1

[0019] See also Figure 1-Figure 3The utility model provides a technical solution: an automatic unloading device for metal processing, which includes: a bracket 1, the inner end of the bracket 1 is connected to a rotating shaft 3, the middle outer ring of the rotating shaft 3 is fixedly connected to a plurality of blocking frames 4, and the end of the blocking frame 4 is an elastic rubber bracket; a unloading plate 2, the two side ends of the unloading plate 2 are symmetrically fixedly connected to guide grooves 8, and a telescopic rod 6 is inserted in the guide groove 8. The upper end of the telescopic rod 6 is fixedly connected to a pull rope 9, and the pull rope 9 is fixedly connected to a segmented falling device; the two sides of the front end of the unloading plate 2 are connected to lever baffles 5, the outer end of the lever baffle 5 is connected to a propulsion rod 7, and the end of the propulsion rod 7 is connected to the telescopic rod 6.

[0020] The blanking plate 2 is used to place metal workpieces so that the workpieces fall along the blanking plate 2 under the action of gravity. At the same time, when the metal workpieces fall to the bottom end of the blanking plate 2, the lever baffle 5 can be pushed to allow the segmented falling device to push and release the subsequent metal workpieces, so that they can be unloaded after the previous metal workpiece is separated from the blanking plate 2; the guide groove 8 enables the telescopic rod 6 to achieve linear movement along the guide groove 8.

[0021] Embodiment 2

[0022] On the basis of embodiment one, the segmented falling device includes a limit groove 12, in which a plug-in rod 11 is sleeved, and a retraction plate 14 is fixedly connected to the lower end face of the plug-in rod 11, and a retraction spring 13 is fixedly connected to the upper end face of the retraction plate 14. The retraction spring 13 is always in an elongated state, and the upper end face of the retraction spring 13 is fixedly connected to the lower end face of the limit groove 12.

[0023] When the metal workpiece is falling, the connecting rod 11 is inserted into the connecting groove 10 under the action of the tension spring 13, so as to realize the clamping of the rotating shaft 3, so that the blocking frame 4 blocks the subsequent metal workpiece.
