[0002] At present, the general process of scrap metal recycling is to first briquette the scrap metal and then melt the briquetted metal to achieve the purpose of resource reuse. This recycling method is also applicable to scrap iron barrels.

[0003] The existing Chinese utility model patent with reference announcement number: CN215360041U discloses a hydraulic equipment for metal recovery, including a recovery box and a feed port, a first cylinder is provided on one side of the first air compressor, a feed port is provided on one side of the first cylinder, a water tank is provided on one side of the recovery box, a water pump is provided on the water tank, a water pipe is provided on the water pump, a second cylinder is provided on one side of the second air compressor, a filter plate is provided inside the recovery box, an extrusion disk is provided on the filter plate, a pressing block is provided on one side of the first cylinder, an extrusion gear is provided in the feed port, a drying device is provided on one side of the feed port, a control switch is provided on one side of the outer frame, a mounting motor is provided on one side of the power cord, and an impeller is provided on one side of the mounting motor. By providing structures such as the feed port, the extrusion gear, and the nozzle, the device is more practical, which not only makes the briquetting efficiency higher, but also keeps the inside of the recovery box clean.

[0004] Since the oil drum is a tubular structure with closed ends, and an opening is provided at the upper end for injecting fuel into the interior, the existing hydraulic equipment for metal recovery generally performs vertical extrusion during extrusion to squeeze the oil drum into a pancake shape. During the extrusion, the overall volume of the oil drum decreases, the internal air pressure increases, and the top opening is in contact with the pressure structure, so the internal air cannot be discharged quickly, which may cause the wall of the oil drum to burst under the influence of the air pressure. At the same time, the existing extrusion equipment has an unlimited position structure, and the oil drum may be displaced due to the influence of the metal toughness when the extrusion is completed, resulting in part of the oil drum being located outside the upper pressure structure, affecting the extrusion effect.

[0016] 1. The utility model provides a movable plate, a rectangular opening structure is provided in the center of the bottom plate, and the connecting column is symmetrically installed under the bottom plate front and back and left and right with the center of the support plate as the reference. The connecting column vertically penetrates the top of the support plate from bottom to top and is fixedly connected to the bottom end of the movable plate. A sliding connection is formed between the connecting column and the support plate. When the rodless cylinder drives the pressing block to move downward, the puncture tube contacts the top of the oil drum and applies a downward force to the oil drum.

Before the oil barrel is flattened, the puncture tube will penetrate the top of the oil barrel until the top of the oil barrel contacts the bottom surface of the lower pressing block. This method can limit the position of the top of the oil barrel while connecting the inner cavity of the oil barrel with the outside world. In the process of extrusion, the air inside the oil barrel can be discharged through the puncture tube and the exhaust hole, so as to avoid the situation where the oil barrel wall bursts due to the influence of air pressure.
