Abstract
The utility model discloses a wire cutting machine idler pulley, which comprises an idler pulley body. The wire cutting machine idler pulley is characterized in that the curved surface of the idler pulley body is provided with a silk thread slot along the circumference direction; the curved surface of the idler pulley body is sheathed with a protecting jacket; the protecting jacket is provided with a gap which corresponds to and is communicated with the silk thread slot; two ends of the protecting jacket outwards extend to form V-shaped wings used for retaining water; two ends of the wing are higher than the middle position of the protecting jacket; the wing is wider than an idler pulley installation reservation slot on a thread stand. According to the wire cutting machine idler pulley disclosed by the utility model, stream downwards flows along a V-shaped groove formed by the wings by the V-shaped wings, spray generated when water collides with the wings is blocked out of the idler pulley installation reservation slot without flowing into a bearing on a center shaft, so that the bearing is not affected, and the service life of the bearing is prolonged.
Description
Technical field
The utility model relates to a kind of improvement invention of guide wheel, particularly be a kind of wire cutting machine guide pulley.
Background technology
The molybdenum filament of wire cutting machine is through guide wheel transmission, existing wire cutting machine guide pulley is in order to reduce the inertia of guide wheel in the time running up, guide wheel blade is done very thinly, only there is 1-2mm, silk thread groove on guide wheel only has 0.5mm, just very large because molybdenum filament being placed on to difficulty in silk thread groove, accidentally molybdenum filament will slide on central shaft, so not only can cut bad workpiece, guide wheel and bearing, but also can cause molybdenum filament card disconnected, in the cutting on line course of work, molybdenum filament has slight jitter, and the problem that also there will be molybdenum filament to run out of silk thread groove occurs; And saponification liquor can be taken in bearing by molybdenum filament in cutting work, thereby affect service life of bearing.
Summary of the invention
In view of the technical problem that background technology exists, the technical problems to be solved in the utility model is to provide one and is convenient to molybdenum filament placement, turns round stable and avoid saponification liquor to flow in bearing, the wire cutting machine guide pulley that extends the service life of bearing.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme to realize: this kind of wire cutting machine guide pulley, include guide wheel body, the curved surface that it is characterized in that described guide wheel body is along the circumferential direction provided with silk thread groove, and be arranged with protective jacket on the curved surface of described guide wheel body, described protective jacket is provided with gap corresponding with silk thread groove and that communicate, the two ends of described protective jacket stretch out and form " V " type assistant that dash is used, the two ends of this assistant are higher than the centre position of protective jacket, and the width of assistant is greater than the width of coil holder upper block installation preformed groove.
The inwall of coil holder upper block installing hole is pressed close at the two ends of described assistant.
Described protective jacket adopts the little material of density to make.
Described protective jacket is plastic sheath.
The utility model is provided with protective jacket on the curved surface of guide wheel body, described protective jacket is provided with gap corresponding with silk thread groove and that communicate, and the two ends of this protective jacket stretch out into " V " type assistant, widened like this thickness of guide wheel blade by protective jacket, thereby facilitate workman that molybdenum filament is placed on to the silk thread groove on guide wheel body, protective jacket adopts the little material of density to make, lightweight, can not increase the inertia of guide wheel in the time running up, particularly plastics, not only easy to process, and production cost is low; The width of described " V " type assistant is greater than the width of coil holder upper block installation preformed groove, so not only can make current along assistant form V-type groove toward dirty, and the spray producing when the collision of water and assistant has also been blocked in guide wheel and has installed outside preformed groove, can not flow in the bearing on central shaft, thereby can not have influence on bearing; And the two ends of assistant are while pressing close to the inwall of coil holder upper block installing hole, assistant is equivalent to guide wheel that preformed groove and bearing isolation are installed, and so further avoids saponification liquor to contact with bearing, thereby makes bearing protected.
Brief description of the drawings
Further describe operation principle of the present utility model and details thereof below in conjunction with accompanying drawing.
Fig. 1 is bilateral guide wheel of the present utility model.
Fig. 2 is monolateral guide wheel of the present utility model.
Fig. 3 is that the utility model is arranged on the structural representation on coil holder.
Detailed description of the invention
With reference to accompanying drawing, this kind of wire cutting machine guide pulley, include guide wheel body 1, the curved surface 2 of described guide wheel body is along the circumferential direction provided with silk thread groove 3, and be arranged with protective jacket 5 on the curved surface 2 of described guide wheel body, described protective jacket 5 is provided with gap corresponding with silk thread groove 3 and that communicate, the two ends of described protective jacket 5 stretch out and form " V " type assistant 6 that dash is used, the two ends of this assistant 6 are higher than the centre position of protective jacket, protective jacket 5 just has the groove 4 of V-type, and the width of assistant 6 is greater than the width of coil holder 11 upper blocks installation preformed grooves 10, the inwall 9 of coil holder upper block installing hole 8 is pressed close at the two ends of described assistant 6, gap between the inwall 9 of assistant 6 and guide wheel installing hole is less, it is just less that the spray that saponification liquor collision assistant 6 produces enters the intrinsic possibility of guide wheel, being equivalent to V-type assistant 6 installs preformed groove 10 by guide wheel and isolates, saponification liquor is only entered in this V-type groove 4, like this saponification liquor along groove 4 toward dirty, and the spray that saponification liquor sweeps away to produce is also isolated in outside V-type groove 4, current just can not got bearing 7 wet like this, thereby avoid bearing 7 impaired, efficiently solve the molybdenum filament existing in background technology and easily depart from silk thread groove defective work piece, the problem of guide wheel and bearing and saponification liquor flow to and in bearing, cause the impaired problem of bearing, and protective jacket 5 has been widened the thickness of guide wheel blade, be more convenient for placing molybdenum filament, wire cutting machine is in the time of work, molybdenum filament can not depart from guide wheel protective jacket and guide wheel body yet, ensure machine steady running, protective jacket 5 adopts the material that density is little to make in addition, such as plastics, aluminium etc., lightweight, can not increase the inertia of guide wheel in the time running up, the present embodiment is adopted made of plastic, not only easy to process, and production cost is low, in addition, the utility model is not only applicable to bilateral guide wheel, and is applicable to monolateral guide wheel.
