Description

Hub lugs and cage arms have additional holes for repositioning the forming rails.

In addition, the tailstock consists of a base mounted on the frame, a carriage carrying a rotating body and a drive nut, and a threaded roller with a feed handle that interacts with the carriage nut, while the base is pivotally mounted on the frame.

At the same time, the driving and driving gears of the cutting mechanism are made conical.

FIG. Figure 1 shows a machine for making reinforcement cages in plan; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 - clamp for reinforcing wire, side view; in fig. 6 - section G-Y in FIG. five.

The machine consists of a guide frame il, on which the rotational drive and feed 2 is mounted, which kinematically connects the shaft 4 of the booster 5 and the screw 6 of the feed mechanism through chain transmission 3. The conductor is made of molding rails 7 of box-shaped section provided with races 8. From the drive side of the rake, they are pivotally connected to the hub 9 fixedly mounted on the shaft 4, in the races 10 of which two holes are made. On the opposite side, on the splines of the shaft 4, a movable casing 11 is mounted. LUTTERS 12 cages are hingedly connected to the forming rails 7 by means of pivoting levers 13, in which three holes are made.

In the annular groove of the yoke 11 there is a split holder 14 attached to the flywheel 15 fitted with a nut 16. The jig rests on the one hand on the sub-node 17, and on the other on the tailstock 18, the cone of which contacts the tapered bore of the shaft 4.. consists of a carriage body 19, in which a sub cone node 20 of a cone and a nut 21 of a feeding device 22, made of a threaded roller 23 with a handle 24 rigidly mounted on it, are placed. The carriage body 19 is provided with four rollers 25 that can be moved in the veller guides 26 of the base 27. On the base 27, there is a bracket 28 for the feeding device 22.

A hinge 29 is mounted on the bed 1 of the machine, connecting it with the base 27 of the tailstock 18, the fixed stop 30 and the folding stopper 31.

The screw 6 of the feed mechanism communicates with the nut 32 mounted on the dressing mechanism 33, in the casing of which the right rollers 34 are mounted for free rotation around the axis, the upper pair of rollers being mounted on the hinged levers 35 with the possibility of adjustment with screws 36. 33 is mounted on wheels 37 moving in rails 1 and provided with cylindrical guides 38 for a handle 39 for feeding the cutting mechanism 40. The latter is connected to the handle 39 by means of a conical gear edachi 41 schestern knowledge which is rigidly mounted on a threaded spindle 42, one end of which is rotatably mounted in the housing straightening mechanism 33 and the second (threaded) is reacted with a nut 43

trolley 44 mechanism 40 cutting.

On the trolley 44, an engine 45 is mounted, connected by means of a V-belt transfer 46 to a cutting disk 47. On one of the rails 7 of the conductor 5, a clip 48 for reinforcing wire, consisting of a pivotally mounted spring-loaded clamp 49 with a notch and a wedge with a thread 50, is in contact with prilsim 49. The wedge 50 has the ability to move by means of a screw 51 mounted on an U-shaped rack 52 fixedly mounted on the forming rail 7 of the jig 5. The control panel has, in the extreme positions of the mechanism for editing the assemblies These limit switches 53 and 54, the latter being set depending on the desired length of the helix.

The machine works as follows.

In the initial position, the dressing mechanism 33 and the cutting mechanism 40 connected to it by the roller 42 are located in the extreme left position — the limit switch 53 is clamped. A wire from the coil holder (not shown) is passed between the rollers 34 of the dressing mechanism and the upper right rollers are adjusted using screws 36. The end of the wire is set under clamp 49,

The screw 50 moves the wedge 50, while the wire is firmly pressed against the rail 7 of the conductor 5. The limit switch 54 is set to the position corresponding to the required length

spirals.

The actuator 2 is turned on, at the same time the jig 5 with the wire fixed on it begins to rotate and the straightening mechanisms 33 and the cutting 40 move horizontally, i.e. the spiral is being manufactured. From switch 54, drive 2 stops, and the last turn of the helix is tied up with annealed wire to the preceding turns and

the cutting engine motor 45 is turned on. By rotating the handle 39 through the bevel gear pair 41 and the threaded roller 42, the carriage 44 of the cutting mechanism is fed to the side of the dressing mechanism 33; with the drive

47 cuts the reinforcing wire. Then, by turning the handwheel 15, the right ends of the rails 7 of the conductor 5 are brought to the axis by rotating the handle 24 of the feeding device 22, the cone is pulled out of the hole of the shaft 4 .. A wedge 50 is withdrawn with a screw 51, and a compression spring between the rail 7 and the clamp 49 retracts from the reinforcing wire. The stopper 31 leans back and the tailstock 18 rotates relative to the hinge 29 through an angle of 90 °. The finished helix is removed from the conductor 5. After that, by rotating the mechanism 15, the yoke And moves against the stop into the collar of the shaft 4, while the rails 7 of the conductor 5 are set in a horizontal position. The tailstock 18 is rotated to the fixed stop 30, the hinged stopper 31 is installed, and through the feeding device 22, the housing .19 of the tailstock is fed to the side of the conductor up to the stop of the cone with the shaft hole 4. The drive 2 is reversed until the end switch 53 and the handle 40 are actuated is retracted from the straightening mechanism 33. The cycle is repeated. Reinstallation of the rails 7 of the conductor 5 into the additional openings of the ears Yu and the levers 13 allows the manufacture of spirals with different cross-sectional sizes. Claim 1.
