Threadrolling machine with device for unloading workpieces
A rolling machine comprises parallel guides delimiting a workpiece conveying channel extending from a plurality of per se known rolling tools to a machined workpiece unloading arrangement, wherein, upstream of the workpiece unloading arrangement, one of the channel delimiting guides is operatively coupled to a structural element swingably supported by a pivot pin, the structural element being integral with the piston rod of a cylinder-piston unit slidably driving the structural element together with the channel delimiting guide, thereby providing a side unloading opening for the workpiece.
1. A rolling machine, comprising:
a machining station for machining workpieces;
a pair of parallel, elongated, feed guides extending to the machining station and bounding a feed channel along which the workpieces are conveyed to the machining station;
a pivotable unloading station mounted on the rolling machine downstream of the machining station for pivoting movement between a working position and an adjusting position, the unloading station having a pair of parallel, elongated, unloading guides bounding an unloading channel along which the machined workpieces are conveyed away from the machining station;
a drive on the unloading station, and operative in the working position, for moving a movable member between a blocking position in which the movable member blocks the unloading channel and diverts defective ones of the machined workpieces away from the unloading station along one path for collection of the defective workpieces, and an unblocking position in which the movable member unblocks the unloading channel and permits passage of non-defective ones of the machined workpieces away from the unloading station along another path for collection of the non-defective workpieces;
a first manual control on the unloading station, and operative in the adjusting position, for moving the unloading guides towards and away from each other in a direction transverse to the elongation of the unloading guides to adjust a width distance between the unloading guides; and
a second manual control on the unloading station, and operative in the adjusting position, for moving the unloading guides in elevation relative to the feed guides.
2. The rolling machine according to claim 1 , wherein the movable member is pivotably mounted at the unloading station, and wherein the drive is a piston and cylinder unit operable for pivoting the movable member between the blocking and the unblocking positions.
3. The rolling machine according to claim 1 , wherein the unloading station has a side opening through which the defective workpieces are diverted in the blocking position.
4. The rolling machine according to claim 1 , and a manual lock on the unloading station for locking the unloading station in the working position.
5. The rolling machine according to claim 1 , wherein the unloading station extends along a vertical plane in the adjusting position.
