A shear press for scrap including a machine body defining a compaction channel to contain the scrap and guide it in a sliding manner along a predetermined advance direction a compaction unit and blades. The compaction unit includes two mutually opposed jaws articulated to the machine bod according to axes of rotation parallel to each other and orthogonal to the advance direction of the scrap, and actuating members to rotate the jaws around the respective axes of rotation, in opposite directions, between an open configuration and a closed configuration. Each aw includes an operating surface to laterally de-limit the compaction channel when the jaw is in open configuration. The extreme point of a first rectilinear stretch with respect to the axis of rotation of the jaw is aligned to the latter along a direction of alignment which forms, with the first rectilinear stretch, an angle having its vertex facing the inner part of the compaction channel.

The device is a self-powered shearing press, press or shears, namely a shearing press, press or shears provided with its own mechanism for movement.

Herein described is a machine (10) for processing scrap (R) comprising: a container body (15) which defines a volume for receiving the scrap (R) and which comprises an opening (30) for the inlet of the scrap (R), provided in the container body (15), for access to the reception volume (20), a press (45) suitable to press the scrap (R) and at least partially housed in the reception volume (20), and a shear (70) for cutting the scrap (R) at least partially housed in the reception volume (20). In particular, the inlet mouth (125) is obtained in an upper portion of the container body (15), the press (45) is positioned at a lower height with respect to the inlet opening (30) and the shear (70) is positioned at a lower height with respect to the press (45).

A shear press (100) for scrap is described, comprising a machine body (105) defining a compaction channel (125) adapted to contain the scrap and guide it in a sliding manner along a predetermined advance direction (A), compaction means (155) coupled to the machine body (105) and adapted to compact the scrap in the compaction channel (125), and cutting means (180) coupled to the machine body (105) and positioned at one end of the compaction channel (125) to separate the compacted scrap into portions, wherein the machine body (105) comprises at least two mutually separable blocks, of which a first block (105A) to which the compaction means (155) and the cutting means (180) are coupled, and a second block (105B) defining a portion of the compaction channel (125) adapted to serve as a loading hopper for the scrap to be treated.

A shear press (100) for scrap comprising a machine body (105) defining a compaction channel (125) adapted to contain the scrap and guide it in a sliding manner along a predetermined advance direction (A), compaction means (155) and cutting means (180); wherein the compaction means (155) comprise: two mutually opposed jaws (170) articulated to the machine body (105) according to axes of rotation (B) parallel to each other and orthogonal to the advance direction (A) of the scrap, and actuating members (175) adapted to rotate said jaws (170) around the respective axes of rotation (B), in opposite directions, between an open configuration and a closed configuration, thereby reducing the space between the two jaws (170); wherein each jaw (170) comprises an operating surface (400) adapted to laterally de-limit the compaction channel (125) when the jaw (170) is in open configuration; wherein the cross section of said operating surface (400), carried out with respect to a section plane orthogonal to the axis of rotation (B), comprises an end (405) proximal to the axis of rotation (B), an end (410) distal from the axis of rotation (B) and at least one first rectilinear stretch (415) that is parallel to the advance direction (A) of the scrap when the jaw (170) is in the closed configuration, and wherein the extreme point (420) of said first rectilinear stretch (415) with respect to the axis of rotation (B) of the jaw (170) does not coincide with the distal end (410) of the cross section of the operating surface (400) but is aligned to the latter along a direction of alignment (C) which forms, with said first rectilinear stretch (415), an angle () having its vertex facing the inner part of the compaction channel (125).

A shredder includes a feed screw that pushes the items to be shredded and compacted towards an opening in the shredder via a restrictor that includes a pipe portion leading to the opening in the shredder, the shredder includes a drive motor driving a miller screw which shreds the items to be shredded into acquired size against a cutter plate fastened to a cutter housing to form shredded items, and forces the shredded items into a press chamber.

Provided is a detection system for use in scrap metal shears, which contains a guillotine for cutting scrap metal materials that applies pressure from above on scrap metal materials by a pressing piston and fixed bottom blades that cut scrap metal materials between the guillotine which acts in downward direction and the fixed bottom blades. The system has at least one sensor which is positioned on the scrap metal shear in such a way that it faces sensor reference points designated on the guillotine to follow the cutting axis, detect axial misalignment during the cutting operation and send a signal; and a PLC system which monitors the scrap metal shear and processes the signal received from the sensor to stop the scrap metal shear or warn the operator.

A device for removing a set of springs from a mattress box spring including a mattress box spring support, a pushing block support frame secured to the mattress box spring support, a pushing block supported by the pushing block support frame adjacent to the mattress box spring support, a cylinder for extending the pushing block over a mattress box spring positioned on the mattress box spring support belt, wherein the cylinder is operable to extend the pushing block transversely over the mattress box spring to separate springs attached to a frame of the mattress box spring from the frame, and wherein a plurality of forks extend in front of the pushing block transversely to the mattress box spring support for helping to prevent the springs from folding underneath a bottom of the pushing block when the pushing block is extended over the mattress box spring to separate the springs from the frame.
