Description

Honeycomb aluminum plate hot press capable of automatically cutting

Technical Field

The utility model relates to the technical field of aluminum processing, in particular to a hot press for a honeycomb aluminum plate, which can be automatically cut.

Background

The honeycomb aluminium plate is a new type building material, and is composed of two layers of aluminium plates and honeycomb core plates adhered between the two layers of aluminium plates. Because the honeycomb aluminum plate has the advantages of light weight, high strength, fire resistance, water resistance, sound insulation, moisture resistance and the like, the honeycomb aluminum plate is widely applied to the fields of construction, traffic, aviation, ships and the like.

In the manufacture of honeycomb aluminum panels, the manufacturing difficulty of honeycomb core panels is greatest. The honeycomb core plate is a hexagonal net structure similar to a honeycomb formed by bonding corrugated aluminum foil strips, and the honeycomb core plate is paved on a platform and can bear large force in the vertical direction but cannot bear force in the horizontal direction, so that the honeycomb core plate is easy to deform in the horizontal direction. In view of this, when two-layer aluminum plate carries out the hot pressing bonding with the honeycomb core, the area of honeycomb core is generally greater than the area of upper and lower aluminum plate, and the limit portion of honeycomb core is to surpass the limit portion of upper and lower aluminum plate, can guarantee like this that the honeycomb core can not have the vacancy support in the middle of upper and lower aluminum plate. However, this has a problem in that a large number of honeycomb cores are cut after the hot pressing. Because the honeycomb core plate is formed by bonding aluminum foil strips, common cutting equipment (such as a disc cutter or a plate shearing machine) can enable the honeycomb core plate to be subjected to plastic deformation due to stress, so that the appearance of a section is affected, and a large number of burrs and spines can be formed.

The specific meaning of the above terms in the present utility model can be understood by those skilled in the art according to the specific circumstances.

A hot press for automatically cutting honeycomb aluminum plates, as shown in FIG. 1, comprises an upper press plate 1 and a lower press plate 2, and the structure and function thereof are specifically described below.

Referring to fig. 2, a lower platen 2 is fixed to a frame (not shown), and an upper platen 1 is movable up and down by a hydraulic cylinder (not shown). A circle of lower cutting teeth 4 are arranged and welded on the periphery of the lower pressing plate 2, a circle of upper cutting teeth 3 are arranged and welded on the periphery of the upper pressing plate 1, and the upper cutting teeth 3 and the lower cutting teeth 4 are arranged in a staggered manner. In this embodiment, the lower cutting teeth 4 are trapezoidal teeth with a wide upper part and a narrow lower part, the upper cutting teeth 3 are trapezoidal teeth with a wide upper part and a wide lower part, and cutting edges are arranged on the periphery of the trapezoidal teeth.

The honeycomb aluminum plate 7 consists of two layers of aluminum plates 7.1 and a honeycomb core plate 7.2 adhered between the two layers of aluminum plates 7.1, wherein the honeycomb core plate 7.2 is provided with a hexagonal net structure similar to a honeycomb formed by adhering corrugated aluminum foil strips, and the tooth tip width of the upper cutting teeth 3 and the lower cutting teeth 4 is smaller than the honeycomb hole width on the honeycomb core plate 7.2.

Referring to fig. 3-4, during hot pressing, the honeycomb core plate 7.2 is first placed on the lower platen 2 and then the upper platen 1 is driven to move downwards. At this time, the upper cutter teeth 3 are inserted into the honeycomb holes from above, and the lower cutter teeth 4 are inserted into the adjacent honeycomb holes from below. When the upper pressing plate 1 completely presses the honeycomb aluminum plate 7 on the lower pressing plate 2, the upper cutting teeth 3 and the lower cutting teeth 4 shear the wall of the honeycomb holes. Obviously, the up-and-down shearing mode can prevent the honeycomb core plate 7.2 from being obliquely deformed due to unidirectional force, so that a smooth incision can be obtained, and burrs and spikes can not be left.

With continued reference to fig. 2. In order to prevent over positioning, the technical scheme is further improved, an upper elastic pad 5 is arranged on the lower plate surface of the upper pressing plate 1, and a lower elastic pad 6 is arranged on the upper plate surface of the lower pressing plate 2. The upper elastic pad 5 and the lower elastic pad 6 have elasticity, and the upper elastic pad 5 and the lower elastic pad 6 are respectively pressed on the upper and lower plate surfaces of the honeycomb aluminum plate 7 when hot-pressed. This design ensures that the shearing of the honeycomb core plate 7.2 by the upper and lower cutting teeth 3, 4 is not hindered while the honeycomb aluminum plate 7 is pressed.

In this embodiment, the upper and lower elastic pads are heat-resistant rubber pads.
