DE202006007587U1 - Set of blades for metal sheet cutting device, comprising curved front areas for use on grid or wire mesh - Google Patents

Abstract

The special set of blades (2,4) can be attached to an electrically or pneumatically operated and manually guided standard device with a cutting table (1) used for the cutting of metal sheets. Each of the blades (2,4) is longer than the blades used on a plain sheet and has curved front areas (3) in order not to get caught when cutting through a wire mesh or a thin metal grid. The blades (2,4) are joined to the device with screws (6) in a particular way for avoiding a lateral motion and can be adjusted if required.

Description

Of the in the protection claim specified invention is based on the problem that with electric or pneumatic hand cutting machines, which for separating thin ones Metal sheet panels are used, grid mats not, or only unsatisfactory can be cut. This application option is not met by most devices. It this concerns wire mesh, metal or plastic covered wire mesh, or plastic mesh. The commercially available devices have only one short, scissor-like opening the two cutting blades. Mostly a horizontal, fixed arranged blade, in a so-called cutting table attached to the device, and one moved vertically with a plunger Cutting. Here, sheet metal from 1 mm to about 2.5 mm thickness scissor-like separated. For metal sheets, this short guide is sufficient. When disconnecting of mesh or wire mesh, the mesh or grid holes get caught in the leadership or cutting table mechanics.

Become these cutting blades now in rounded, bent and elongated Formed, the supplied on wheels or mats raw material, with the hand-guided Machine without impose or block, use to separate the mesh braid. By using a complementary Cutting blade retrofit kit, consisting from cutting table with fixed knife and the cutting blade for the Pestle, as well the fasteners, is considerably elongated by the scissors-like opening, the use of the above-mentioned devices for cutting wire mesh, Perforated sheets, wire mesh, wire mesh or plastic mesh allows. The separation of sheet metal sheets is also to a certain thickness possible.

The Invention is based on the consideration with a suitable extension kit, commercially available handsets for cutting sheet metal sheet, so to retrofit that especially wire materials but also perforated sheets and sheet metal sheets etc. can be cut.

Claims (1)

Cutting blade retrofit kit for use on electric hand cutting machines, which are for cutting metal or plastic boards on the market. Consisting of a cutting table ( 1 ) for feeding the cuttings and receiving the lower knife, the lower knife ( 2 ) with run-on slope ( 3 ) and an upper knife mounted on the machine tappet ( 4 ). The components are characterized in that the upper and lower cutting knives, a larger and thus a longer scissor opening ( 5 ) as in the knife sets for cutting metal sheets. Characterized in that at the lower knife ( 2 ) a run-on slope ( 3 ) is provided so that, for example, a wire mesh web without inhibiting effect or hooking the machine in operation via the cutting table ( 1 ) can be supplied. Against twisting or pivoting and thus blocking the cutting blades, suitable means for fixing the blades are used in addition to the screwing. It can do this in addition to a screw fastening ( 6 ) a transverse to the cutting direction guide groove ( 7 ), or alternatively the leadership by cylinder dowel pins ( 8th ). A readjustment of the cutting air with adjustment screw ( 9 ) is taken into account. The plunger is secured and guided against radial torsion, so that the cutting blades always remain in parallel and do not twist, and thus can meet. This is achieved by using a correspondingly shaped washer ( 10 ), which on a milled surface ( 12 ) is performed on the round plunger guaranteed. For exact fixing of the washer, this is eg with the machine body by means of heavy-duty pins ( 11 ) connected.
