SU96009A1 - Automatic cutting machine for cutting metal, in particular, ferronickel tubing - Google Patents

Description

At present, cutting of metal, in particular ferronickel-iron tubes (with a diameter up to Zlsh and a length of 5 to about 25 lx), intended for glass bushing insulators, is carried out on lathes. This method of cutting is not very productive.

The proposed automatic cutting machine has a significantly higher productivity. This is achieved due to the fact that in order to break off the preheater in the machine (but the tube cut by the knife blade on the rotating head carrying the disk knives, at some distance from the cutting plane, are located on two parallel planes located on both sides of the head axis adjustable stop C of the radially movable push-up rusk. In order to carry out periodic radial movement, the crumbler during rotation of the head QH is mounted on a rotating carriage under the influence of the At the head of the rocker kinematically associated by sliding clutch with the drive cam mechanism of the machine.

FIG. 1 shows the described auto gatic machine; in fig. 2-head CTHHKia.

On housing 6, all components of the automaton are mounted. It can be cast or welded. The spindle 4 is the axis on which the head and the distribution drum rotate. In the spindle there is a hole in which the pusher 16 is placed and in it a guide tube 18. At the front end of the spindle there is a thread for the stop nut 38 of the front clip. Three jaws 39 with a tapered clamping hub 4 are placed inside the front spindle of the spindle.

In the middle part of the spindle, on the outer diameter, there is a cone, which when installed enters the old hole and is tightened with nuts 15. The machine head (Fig. 2) rotates on two ball bearings and is intended for notching and breaking off. It consists of a body 2 and a flange 1, with which the cams 50 and 56 are fixed, the stops 53 and 54, the levers 55 and 38. The roller cam 50 rotates in the cone of the flange /, and the movement starts from the cone in the sleeve 3 through lever 58.

The cam 50 of the roller moves during the tube feeding due to centrifugal force. Cutting roller 51 is fixed by spring 52. K-blade 56 lomat rotates on a cylindrical pin and receives movement from the tapered bushing 3 through lever 55. The cam moves away under the action of centrifugal force. When translating the automat to another length of the tube, under the laminate of the mattress, sanding strips are inserted that correspond to the length of the cut tube so that the breaker abuts the tube 2-3 millimeters from the free end.

The seats on the cams 50 and 56, B, which abut the adjustment knobs of the levers 55 and 55, are reinforced with carbide plates. The levers 55 and 58 have screws for adjusting the depth of the embedding of the roller to the steepness of the tube. Roller stop 54 is fixed on the holoske with the help of two; zine: o; 3: the working part of the cam is reinforced with a plating plate; solid; and processed on an electric spark machine (hole processing); roller window is cut by abrasive). When niranchki nstiranni of solid production is carried out adjusting emphasis vpit 57). The stop 53 of the plate is fixed by one screw and consists of holodgles and the stop, soyediyiyy counter. studs. The stop is reinforced with a hard metal plate and treated with abrasive. When transferring the machine to another length of tube to be cut, replace the stop block and set the stop so that the cut comes along the stop plane. For each size of the tube to be cut, make a separate block. When the carbide plate is worn, adjustment is made with a screw.

The distribution drum 9 is rotated on two ballpoint knobs. On the central surface there are four jaws to fall and clamp the tube. On the left end there is a cam, for feeding the bushing 3 with the coupling 8 and the lever 37. A drive pulley 11 is fastened to the tube supply cam on the side.

The clamp is used to fasten the tube during the opening and consists of three clamping cams 39, a tapered sleeve 41, a stop nut 38 and a push rod 16. The clamp receives force from the spring 31 through the push rod 16 and the lever 17- Release comes from the distribution drum 9 through the slide 43 and lever 17.

The tube feeding mechanism provides after-flow with an accuracy of ± OD mm (accuracy of billet production at normal ± 0.2 MM). The feed mechanism consists of a carriage 20, on which there is a clamping bar, and on after | Dyuu presses the pressure roller 22, receiving a clamping force from the spring of the lever 13, sitting laa of the same axis with the lever 14. Dilution, it comes from the distribution drum 9 which raises the lever 13.

8 the carriage is a replaceable insert, having a longitudinal groove, whose diameter is equal to half the diameter of the tube; the same groove is on the pressure plate. Such a clamp design ensures that the tube is clamped and prevents its deformation.

When the machine is turned to another tube diameter, it is necessary to change the carriage liner and clamp bar, then adjust the position of the lever roller / 5 with respect to the cam of the distribution drum 9 with screw 21. Adjusting the wear of the liner and pressing the plate should be done with screw 1 /.

The carriage receives movement from the p-distribution 1: telny drum through the wings 36 and the feed lever 30. Return the carriage to the stubborn adjusting 26 nroizolite prummm: -U. The length of the tube being cut is set by adjusting the absorbed 26. The supply of the tube takes place at that moment when the front and rear clamps are unclasped and the clamp 1 is clamped. Rear clamp 23 sec. LL clamp the pipes: and at the time when the carriage moves backwards and does not allow the carriage to push the tube back.

The rear clip 23 consists of a body into which a replaceable insert and a nrlimimilanca are inserted. The clamping force of the lever 14 is obtained from the spring and, through the pusher, presses the clamping bar. Decompressing occurs with the help and lifting of the yo: aha 4 from the distribution drum on.

When converting the machine to another diameter of pipes, the liner and clamping plate are measured. To remove the tubes that are scattered during the section, a folding cylindrical 1 is placed on the head (G (cover, rojXu, which is 0.3 mm not up to the screw head); below there is an opening for the workpieces to go to the box. machine. Lubrication of the machine can be local and from the reservoir, the possible removal of lubrication points.
