Embodiment Construction

[0066] Referring to the attached table of drawings, the reference numeral (100) generally indicates the improved pneumatic cutting device with vibrating blades for a leather cutting machine of the present invention.

[0067] The improved pneumatic cutting device (100) comprises some of the same features as those of the aforementioned and said patent applications belonging to the same applicant, especially with regard to the usual general features present in pneumatic cutting devices.

[0068] Therefore, in the following description, the same references will be used to indicate the parts of the improved pneumatic cutting device (100) of the present invention, which parts correspond to the parts of the cutting device of the above-mentioned patent application.

[0069] Thus, the improved pneumatic cutting device (100) comprises a body (C), a cutting blade (L) for cutting a leather piece stretched on a working plane (leather piece and working plane not shown).

[0070] In this reg...

Abstract

An improved pneumatic cutting device (100) comprises an oscillating chamber (1); an oscillating piston (10) having a head (13), predisposed in the oscillating chamber (1), and a rod (14) connected to a cutting blade (L); a pneumatic activating system (P) communicating with the oscillating chamber (1) so as to pneumatically activate the oscillating piston (10) to oscillate in the oscillating chamber (1) and thus cause the cutting blade (L) to oscillate vertically. A first lower cylindrical cavity (162) is present under the oscillating chamber (1), and a second upper cylindrical cavity (161) is present over the oscillating chamber (1), and the rod (14) comprises a first lower rod part (22), in the first lower cylindrical cavity (162), and a second upper rod part (21), in the second upper cylindrical cavity (161). The pneumatic activating system (P) comprises: a main annular switching chamber (30) and an annular discharge chamber (40), realized in a portion of the walls of the second upper cylindrical cavity (161). The second upper rod part (21) cooperates with the pneumatic activating system (P) for the switching of the oscillation stroke of the oscillating piston (10).

Description

technical field [0001] The present invention relates to the technical field of cutting machines for cutting sheet materials, such as leather, leather pieces, hides, synthetic leather, etc. [0002] More specifically, the present invention relates to a cutting device having an improved aerodynamic vibrating blade to be mounted on the cutting machine. Background technique [0003] As is well known, a cutting machine comprises: a working plane in which materials to be cut, such as leather sheets, synthetic leather, etc., are arranged; a frame mounted above the working plane; blade. [0004] Also included is movement means carried by the frame and movable relative thereto for moving the cutting means according to three Cartesian coordinate axes above the work plane. [0005] In this way, the cutting blade can be positioned above the leather sheet, lowered to score the epidermis, and moved according to a given cutting path in order to cut the epidermis according to preset and / o...
