Description

In the proposed machine for mass production of wooden reels, the cylindrical cylindrical billet coming from the magazine enters the recesses of the rotating drum and, kept from its own rotation by an endless chain with jagged links, is drilled by pulling on the drill, under the action of a buccal ring, and the drill is also as well as the workpiece, placed in a rotating drum. Subsequently, the billet with a drilled axial bore is machined with mills, giving it the desired shape, after which the coil is ready and the reel is dropped into a special chute.

In FIG. 1 shows a front view of the machine with a partial cut; FIG. 2-side view of the machine; FIG. 3-section of CHPS1 gutter; FIG. 4-5 is a side view of the cutting tools.

The proposed machine consists of two similarly working parts, symmetrically located relative to the plane / - /.

On the main shaft b (Fig. 1) of the machine on a conical thickening of his collar mounted 7, composed of two halves. Around the wheel 7 are spindles 9 with double gear gears 9 Spindles 9 carry drills // and

(129)

rotate on ball bearings 72, mounted in the corresponding recesses of the main drum / 5, which is loosely mounted on the shaft 6 and consists of two halves bolted together. The recesses with bearings are covered with J4 caps to prevent oil on the coil being processed and to prevent the mechanism from clogging with wood dust. Grooved rims / 5 are screwed to the drum 75 so that the axis of each groove coincides with the axis of the drill 77. Against each drill, along the common axis on the opposite side of the drum, channels J6 are drilled into which spiral springs 76, pushers 77 and balls 75 are inserted. 20 does not allow pushers and balls under the action of springs to jump out of channel 76 and, tightly against the cam ring 27, do not let the dust drop to the pushers.

The main shaft 6 of the stanchions are rotated in bearings 39 located in the housing 38. The housing 38 is provided with cam rings 27 mounted on it and rests on the semicircular sockets of the bed 40 (Fig. 2), on which it is fastened with bolts 4J. Four rods 42 are mounted vertically on the frame 40, on two of which the supports 43, are fastened. 44, carrying pulleys 45, 46, serving to regulate the tension of the chain 47

with serrated links, enveloping pulleys 45, 46.46. On the other two rods 42 there is a wedge-shaped support 49 and a chute 49 which guide the finished coils, as well as the stationary wedge-shaped fist 48. At the top, the rods 42 are attached with their ends to one common plate on which the magazine is located 5 /.

The mechanism that rotates the drum / 5 takes the initial movement from the shaft through gear 23 fixed on it (Fig. 1, 2) and through a gear drive carried out by gear 24, roller 25 and another small gear 26 fixed on it, connected with a large gear 27 (Fig. 2) rotating together with a small gear 28 engaged with a ring gear 28 on the inner surface of the drum 13 and transmitting to the latter a desired number of revolutions.

In the lower part, the machine is equipped with guides along which the slide, like a slide rail, slides 32 with corresponding tides, in which the axes 33 rotate with the mills 5 fixed at the ends and the axes 35 carry the milling cutters 34. The milling cutters 34 (Fig. 1.2) besides translational motion along the guides and rotation around its axis, they can have a swinging movement around axis 36. Axis 36 receives rotation from the electric motor and, through the 37-ЗТ transmission, transmits rotation to the router 34, and through transmission 37-37 transmits the rotation of the axis 33, bearing milling cutters 34.

The milling cutters 34 grind the workpiece; The milling cutters 34, by their purpose, give the coil the required profile accuracy and the required cleanliness of the finish.

FIG. Figure 5 shows a modified workpiece treatment unit consisting of fixedly hardened cutters 40, past which rotating workpieces pass in a continuous stream. The cutters 40 are set appropriately to achieve a processing sequence and gradually grind the workpieces, the chips being removed by a stream of air blown by a fan between the cutters.,

In another modified device shown in FIG. 4, for roughing the blanks, the initial rough machining is done by milling cutters 29, and the final finishing is carried out by a series of knives, respectively delineated and placed in the path of the blanks.

The work of the machine is as follows. Through the pulley 50 (Fig. 1.2), the main shaft 6 receives a clockwise rotation (Fig. 2) from the electric motor or transmission shaft and, through the wheel 7, transmits the rotation of the pinch m 9. At the same time, through the jaw 23 and the gear train 24, 26, 27 , 28, 28 also receives a rotation clockwise of the drum 13. At high speeds of rotation of the spindles 9, their bearings and gears to them are transmitted from the wheel 7 to require continuous lubrication. The latter is achieved in that oil and gears 9 of spindles 9 are poured in the cavity of the drum 13, touching it, transfer oil to the wheel 7 and bearings. When the drum 13 rotates the billet 15, a continuous flow from the magazine 5 / enters the grooves of the rim 15 of the drum 13, and the billet 15 is pressed by the endless chain 47 so that the teeth of the chain 47 penetrate into each billet (Fig. 3) and keep it from rotating when drilled into holes along with the serrated portions of drills 77. Drilling occurs during the entire time that the workpiece together with the drum moves from magazine 57 to pulley 45 (Fig. 2), since in this gap the workpieces are pushed by the cam 21, balls 18 and pushers 77 for rotating the drills P. 7 away from the wheel. After drilling, the workpieces are machined with milling cutters 29, 34, 5 / (figs 2, 4) or knives 40 (fig. 5), while simultaneously the end parts of the coils are machined with a knife 30 (fig. 4) with a curved, specially contoured blade.

Upon further advancement by the drum 13 (Fig. 1, 2) of the finished coils after their complete decoration, they are affected by a wedge-shaped stop 48, which removes the coils from parts 1G of drills 77. Next, the coils are affected

wedge-shaped stop 49, which dumps them into the chute 49, which retracts the finished

coil in the receiver of finished products.

The subject matter of the invention.
