[0025] The compression device for non-ferrous metals according to the present invention is

[0026] In a compression device for compressing non-ferrous metals,

[0027] A main body (2) composed of a rectangular base plate (22), side walls (24) formed on both sides of the base plate (22), a front wall (26) formed in front of the base plate (22), and a rear wall (27) formed at the rear, wherein an opening (240) is formed in one side wall (24) and a space for accommodating non-ferrous metal is provided inside;

[0028] A cover (3) hinged to the upper side wall of one side of the main body (2) and operated to open and close at the upper opening of the main body (2);

[0029] A door (28) coupled to an opening (240) of the main body (2) and opening and closing the opening (240), and a door driving unit (4) for opening and closing the door (28);

[0030] A first compression unit (5) comprising a first hydraulic drive unit (51) mounted on the outer surface of the rear wall (27) of the main body (2), a first cylinder rod (52) coupled to the first hydraulic drive unit (51) and pulled out or pulled in, and a first pressure plate (53) formed at the end of the first cylinder rod (52) to press a non-ferrous metal contained in the space toward the front wall;

[0031] A second hydraulic drive unit (61) mounted on the outer surface of the other side wall (24) of the main body (2), a second cylinder rod (62) coupled to the second hydraulic drive unit (61) and pulled out or pulled in, and a second pressure plate (63) formed at the end of the second cylinder rod (62) to press a non-ferrous metal contained in the space toward the door (28); and

[0032] It is configured to include a hydraulic supply unit (7) connected to the first hydraulic drive unit (51), the second hydraulic drive unit (61), and the door drive unit (4) to supply hydraulic pressure.

[0033] The main body (2) is made of metal and has a rectangular structure having a bottom plate (22) with a predetermined thickness, a side wall (24), a front wall (26), and a rear wall (27).

[0034] The first hydraulic drive unit (51) and the second hydraulic drive unit (61) may be hydraulic cylinders.

[0035] The door drive unit (4) is composed of a cylinder rod connected to one side of the door (28) which is connected to the opening to be opened and closed by a slide, and a cylinder unit to which the cylinder rod is connected, so that the opening and closing operation of the door (28) can be performed by the withdrawal or retraction operation of the cylinder rod.

[0036] Meanwhile, it may include a guiding means (8) formed on the bottom plate (22) of the main body (2) to guide the first pressure plate (53) or the second pressure plate (63) to move in one direction or the other direction.

[0037] The above guidance means (8) is

[0038] A first rail groove (81) formed in a straight direction on the bottom plate (22), and a first guide projection (82) formed on the lower part of the first pressure plate (53) and coupled to the first rail groove (81),

[0039] It is configured to include a second rail groove (83) formed in a straight direction on the bottom plate (22) and intersecting with the first rail groove (81), and a second guide projection (84) formed on the lower part of the second pressure plate (63) and coupled to the second rail groove (83).

[0040] The bottom plate (22) is a metal plate of a predetermined thickness, and a first rail groove (81) and a second rail groove (83) are formed on its upper surface so as to intersect at a right angle with a predetermined length.

[0041] Therefore, the first pressure plate (53) is driven forward along the first rail groove (81), thereby allowing the first compression operation on the object (non-ferrous metal) to be performed.

[0042] Afterwards, the second pressure plate (63) is driven forward along the second rail groove (83), thereby allowing a second compression operation on the object to be performed.

[0043] The object compressed by secondary compression can be discharged to the outside through the side wall opening (240) of the main body (2).

[0044] The above cover (3)

[0045] A plate (32) that closes the upper opening of the main body (2);

[0046] A hinge portion (34) comprising a hinge ring (342) formed at one end of the plate (32), a hinge bracket (344) formed on the outer side of the upper opening of the main body (2) and overlapping with the hinge ring (342), and a hinge shaft (346) fitted and coupled to the hinge ring (342) and the hinge bracket (344);

[0047] The cover driving unit (36) comprises: a mounting bracket (361) mounted on the outer side of the main body (2); a fixed bracket (362) installed on the upper side of the mounting bracket (361); a cover opening / closing cylinder unit (363) hinged to the fixed bracket (362) and formed horizontally on the upper side of the mounting bracket (361); and a cylinder rod (366) coupled to the cover opening / closing cylinder unit (363) to be pulled out or pulled in, and connected to a cylinder ring (364) formed on the upper surface of the cover (3) and an axle pin (365).

[0048] When the cover drive unit (36) is turned on, hydraulic pressure is supplied to the cover opening / closing cylinder unit (363), causing the cylinder rod (366) to advance, and the plate (32) connected to the cylinder rod (366) rotates downward to cover and seal the upper opening of the main body (2).

[0049] Meanwhile, the plate (32) of the above cover (3) is joined to the upper opening of the main body (2) and then includes a locking part (9) that is operated to lock or unlock.

[0050] Referring to FIG. 6, the locking part (9) is

[0051] Housing (92) formed on the upper surface of the plate (32) of the cover (3);

[0052] A locking drive unit (94) having a cylinder unit (941) mounted on the outside of the housing (92) and a cylinder rod (942) coupled to the cylinder unit (941);

[0053] A locking member (96) that is rotatably driven by being coupled to the end of the housing (92) by an axle pin (365), has a hook (962) formed at one end, and the other end is hinge-coupled to the cylinder rod (942) of the locking drive source (94);

[0054] It is configured to include a hook groove (97) formed on the outer surface of the side wall (24) of the main body (2) to which the hook (962) is hooked and fixed.

[0055] Accordingly, when the locking drive source (94) is turned on, the cylinder rod (942) is pulled out so that the locking member (96) rotates in one direction, and the hook (962) moves downward and is coupled to the locking groove (97) of the main body (2), thereby enabling a locking state.

[0056] Conversely, when the locking drive source (94) is turned on, the cylinder rod (942) is retracted, the locking member (96) is rotated in the other direction, and the hook (962) is moved upward and separated from the locking groove (97) of the main body (2), so that the locking state can be released.

[0057] Meanwhile, the hinge portion (34) connected to one end of the cover (3) and the outer side of the upper opening of the main body (2) includes a hinge ring (342) formed at one end of the plate (32) of the cover (3), a hinge bracket (344) formed on the outer side of the upper opening of the main body (2) and overlapping with the hinge ring (342), and a hinge shaft (346) fitted and coupled to the hinge ring (342) and the hinge bracket (344).

[0058] At this time, since the plate (32) is a heavy metal plate, a shock absorbing part (1) is formed to absorb the shock that occurs when it is closed.

[0059] The shock absorbing part (1) elastically supports the rotation of the hinge ring (342) of the cover (3) to absorb the closing shock of the cover (3).

[0060] Referring to FIG. 7, the shock absorbing part (1) is

[0061] A rail groove (121) formed with a predetermined length on the upper part of the main body (2), and a guide projection (12) formed on the lower part of the outer surface of the hinge ring (342) and coupled to the rail groove (121), and

[0062] It is configured to include a hydraulic absorption unit (14) comprising a buffer (141) mounted on one side of the interior of the rail groove (121), and a cylinder rod (142) coupled to the buffer (141) to be withdrawn or retracted and supported at one end of the guide projection (12).

[0063] Therefore, when the cover (3) is closed, the guide projection (12) formed on the lower outer surface of the hinge ring (342) is temporarily moved along the rail groove (121) due to play caused by the load, and the cylinder rod (366) of the hydraulic absorber (14) temporarily stops the movement of the guide projection (12) and absorbs the shock, thereby absorbing the shock of the cover (3) closing and preventing damage.

[0064] Although described in relation to preferred embodiments, those skilled in the art will readily recognize that various modifications and variations are possible without departing from the essence and scope of the invention, and it is obvious that all such changes and modifications fall within the scope of the appended claims.
