摘要:
Bel einer Bohrstation zum Anbringen von Bohrungen unterschiedlicher Größe in einer Platte aus beliebigem Material, die aus Bohrspindel, Bohrer und Bohrtisch besteht, sind Transportbänder (3a,b) vorgesehen, mittels derer die zu bearbeitende Platte (2) zu- und wegführbar ist. Der Bohrtisch besteht aus einem mehrteiligen rahmenförmigen Plattenaufnehmer, (4) der die Platte nur am Rand festhält. Bohrspindel (5a, b) und/oder Plattenaufnehmer (4) sind derart gesteuert bewegbar, daß die Bohrung an jeder gewünschten Stelle der Platte, auch von unten, anbringbar ist. Diese Bohrstation ist mit weiteren, identischen Bohrstationen zu Fertigungslinien verkettbar.
摘要:
The invention refers to a drilling machine for glass panes, which comprises a series of tool-bearing spindles (3) set side by side and mounted on horizontal carriages (1 and 2) located one in the upper part for upper drilling and one inverted, in the lower part, for lower drilling (Figure 1).
摘要:
A machine for working on sheets, particularly a machine for drilling holes in glass sheets, comprising, on a frame (1) for supporting a sheet (2) to be worked, an upper working head (5) and a lower working head (6). A sheet locking assembly constituted by an upper pressing surface (7) and a lower pressing surface (10,11) is provided, the lower pressing surface (10,11) being disengaged from the lower working head (6).
摘要:
An apparatus for drilling plates of glass, marble and similar stony materials comprises a drilling device (DF) having two opposite heads (T, T') for carrying out respective coaxial incisions making up a hole onto two opposite surfaces of a plate under working (L). Each head (T, T') comprises at least a first and a second drilling assembly (G1, G2), the latter being movable on its respective head (T, T') in a perpendicular direction with respect to the drilling axis (A2), so as to take several alternative positions. The variation of the position of the second assembly (G2) with respect to the first assembly (G1) enables to vary the distance between the two holes or their angular position, and to make simultaneously two holes onto the plate (L), even quite close to one another, without moving the whole drilling device.
摘要:
@ A machine is disclosed for drilling sheet-like materials, in particular for drilling holes at preset locations on glass, crystal glass, and the like plate blanks, which includes a feed-in station (1) and a drilling station (2). The feed-in station (1) is provided with a means of sliding a plate blank (3) to be drilled, forward, which has a plurality of rollers (5), at least some of which are driving rollers, the rollers being effective to impart a forward movement to the plate blank (3) and provided with a means of combining this forward movement with an approaching movement of the plate blank (3) toward an abutment member connected to the frame of the feed-in station (1).
摘要:
A spindle assembly for machining a cast workpiece includes a fixture that provides rotational movement to the workpiece around a fixture axis. A first spindle provides rotational movement to a cutting tool around a first spindle axis and a second spindle provides rotational movement to a second cutting tool around a second spindle axis. The first spindle axis and the second spindle axis are transverse to the fixture axis. The fixture is disposed between the first spindle and the second spindle. The pivotal movement of the fixture provides access to opposite sides of the workpiece to the first spindle and the second spindle enabling the cutting tools to simultaneously cut opposing sides of the workpiece. The first cutting tool and the second cutting tool are replaceable by a third cutting tool and a fourth cutting tool to cut an alternative or different aperture into the workpiece.
摘要:
A glass plate hole forming device (1) comprises a recess forming means (8) that, in a recess forming area (2), forms a recess (5) in the upper surface (4) of a glass plate (3) and that forms a recess (6) in the lower surface (7) of the glass plate (3) that communicates with the recess (5), a chamfering means (10) that, in a chamfering area (9) adjacent the recess forming area (2), applies fine chamfering to the edges (12, 13) of the openings in recesses (5, 6) formed in the glass plate (3) by the recess forming means (8), and a transfer means (11) that successively transfers glass plates (3) to be formed with recesses (5, 6) to the recess forming area (2) and that successively transfers the glass plates (3) formed with the recesses (5, 6) to a chamfering section (9).
摘要:
An apparatus (1) for drilling a hole in a glass plate includes recess forming means (8) for forming in a recess forming section (2) a recess (5) in an upper surface (4)of a glass plate (3) and forming therein a recess (6) communicating with the recess (5) in a lower surface (7) of the glass plate (3); chamfering means (10) for light-chamfering, in a chamfering section (9) adjacent to the recess forming section (2), edges (12, 13) of opening of each of the recesses (5, 6) in the glass plate (3) where the recesses (5, 6) have been formed by the recess forming means (8); and transporting means (11) for consecutively transporting to the recess forming section (2) the glass plates (3) in which the recesses (5, 6) are to be formed and for consecutively transporting to the chamfering section (9) the glass plates (3) in which the recesses (5, 6) have been formed.
