SU65256A1 - Milling machine for processing liners, for example, for special packing - Google Patents

Description

This appliance is designed for milling po-null-rounds. It is capacious. In the packaged bags of the special nasa tea (“packing”).

The production grooves in the inserts at the present time are based on two methods: on conventional single-slotted milling machines and on drilling machines. Both methods cannot be considered as crushing, as they do not provide sufficient productivity and processing quality.

In order to eliminate these drawbacks, it is proposed to process the inserts by milling on the proposed machine. A distinctive feature of this rate is the change of the rocker carrying the cutting tool for machining the workpiece on one arm. and on the second shoulder there is a mechanism d, l for controlling: supplying products to an endless chain. This mechanic is a ratchet, which is a moderator for the lead chain. From the box there is a spring with a clamp with a clamp to clamp the thread during the treatment.

In FIG. 1, 2 and 3 depict the proposed machine in three projections, FIG. 4 and - and - the persistent mechanism for preparations and fig. 6 "7 - Feed hopper.

The yoke /, rotatable on axis 2, carries — on one shoulder — the shaft 3 with the cutting head 4, but my water from the electric motor 3 with the aid of a belt transmission 6.

In the upper position, the cutting head 4 extends a certain amount above the level of the table 7, and this value is adjusted as due to the diameter of the head 4, which is sculpted. removable, and through the special screw stop 8.

Shaft 9 with cam W interacts with lever} J and tension 12, which is pivotally connected with the beam. A camshaft .9 receives rotation from a separate electric motor J3, connected via a stepped belt drive 14 to a gearbox 15, consisting of a CERIFIED pair Ifif / and spur gear 166. When the shaft 9 rotates, the cam 10 pumps the lever // a. consequently, there is also a / with a cutting head 4. At the same time, thanks to the spring and not 17, the rocker arm / is always pressed to a hard stop 5, which ensures the necessary precision of processing. The slits 18 in the yoke / and the lever 11 are provided for adjusting the swing amplitude of the yoke /, and the screw 19 for adjusting its initial position.

The mechanism for feeding inserts consists in a safe “20” chain with stops 2: / thrown over two rounds: 22, of which one is 226 {FIG. 2) at each swing of the left hand end of the rocker arm / it turns downwards by a certain angle noi hour hand, thanks to the connection “0” and 24, the lever 25 with the friction dog 26 and the friction disk 57, connected to the shaft 28 by means of an adjustable friction clutch 23, the second half of which is wedged on the same shaft i S S, which is on the boot 226. Coupling 23 is inserted so that the stroke of the friction disc 27 is U; always 1 is greater than the pitch between the recesses of the on-ear, which provides the following: to hard stop. T ha 24 Connected to lever 25 by means of an elongated notch 29 (FIG. 1), which is done so that the turning of the disk 57 lags somewhat behind the beginning of the swing of the box;: hkla -1. The screw 30 serves for fixing the horizontal position of the reverse (idle) movement of the lever 25, and the slot 31 for adjusting the angle of rotation of the disk 27, and consequently, the turret 226.

For: inserts clamps are applied: D1we of rulers 32 ic with flat springs 55, hingedly hanging on a common "34 n symmetrically-pressed on the liner; a in the head, and on the size of inserts. In order to facilitate the movement of the insert for milling the subsequent excavation, the rulers 52 can move away from the inlet, breathing 35, THAT is achieved by means of the arc bus 59 fixed in the sump of the yoke,

with the roller 40 of the shank 41, made at the same time with a vertical ruler 32. When lowering the left end of the rocker arm / woman 39 squeezes the roller 40, whereby the ruler 32 consumption and spring 33 release the liner 35.

The ynopia inserts mechanism (Figs. 4 and 5) represents a frame 2 swinging about the axis, carrying a number of mobile ynopOiB 43 projectiles that can be fully recessed (43a) under the control of the Tripod 55 or a stop (stop 456) for (The position of the 55 ino insert is fixed to its end face. 42 initially deviates from the insert 55, and then returns again, again.

The feed hopper (Fig. 6 and 7) consists of a carriage 47 with rear stops. 48, moved with the help of the load 49 in the direction of the chain 20, the limited ruler 50 and the bracket 5 /.

The receiving bunker (Figs. 1, 2, 3) provides bottom-pressing arcuate-shaped wrinkles 52, onto which treated inserts fall by their own weight.

The box-type frame 55 provides for the fastening of all machine components and equipment, which is equipped with doors 54 for access to the described mechanisms, the belt and the knife head.

The start and stop of the machine is performed with) noLMonj, H button 55 (Fig. 1).

The machine works as follows.

The material to be processed is put in bundles into the feed hopper, for which the key 47 is removed by the handle 55 ((Figs. 1, 3) from the chain 20 and then released. The swaying roll is weak / at each empty passage (lowering the end 10 down) produces the following | operations: 1) deviation ramky 42 s

stops 43, thanks to the tire 44, after which the stop 43c, holding 1 to this insert 35, moves away from the torda, “the insert can be moved; 2) noiBopOT pressure lines 32 with spring 55, thanks to the tire 39, due to which the liners 35 are released from the action of the clamp and can be removed; 3) turning the fries: a zio diac 27 and a shaft 28 with a half of the friction clutch 23, thanks to the 24, the lever 25 and the pawl 26, as a result of which the inserts fastened by the abutment 21 of the chain 20 will be shifted for subsequent milling; with this, the shift will occur all the way into the next spring pin 43, since by this time the frame 42, the swing of which is controlled by the tire 44, will return to its original position.

During the reverse course to the rymy / (lifting the left end), the following operations will occur: 1) the clamping ruler 32 in connection with the bend 39 returns to its original position and clamped - the inserts 35, thanks to the spring 36; 2) frame 42 will perform one swing, while, OD fa ko, the position of the stops does not: change, nor will anything happen to the inserts, since they are in the pressed state; 3) the lever 25 with the dog 26 turns idle to its original position and the control unit; rets into the screw 30; 4) the cutting head 4 will begin to slide and a recess will be formed in the insert 55, which will

occur until the yoke pack / does not abut the restrictive stop 8, after which there will be a REP.
