An ingenious solution processing grinding wheel internal surface of tubes or hollow parts offered innovators N. Epifanov, A. Chuprikov, Y. Shabalin.
Yes, how would it work, no matter how perithecial — it does not decrease! To maintain a times a predetermined diameter with high accuracy allows her to design feature.
Very often for finishing wood products use burning. Even if this operation is performed by a special device — cautery, it is very time consuming, especially when applied to a variety of complex patterns. I want to offer successfully tried mechanized method of burning intricate patterns and various applications. It is much more productive than the traditional method and besides, it was pretty spectacular.
Not only the shipbuilders there is a need for one-time, single steel casting of certain parts. In these cases, existing technology has to pre-make a wooden model to receive the outdoor imprint in the mold and core boxes for the formation of internal cavities of the casting. The complexity of manufacturing of model kits three to five times higher than the complexity of manufacturing of the castings.
The working head of the machine, snake obviouses his bracket around the pipe, produces a hissing blue tongue of flame. Licking the metal, as if it bites into him and now burns through, slowly slitting thick wall pipe.
When repairing machinery, especially agricultural, are quite common and at the same time melomakarouna operations cutting of sheet iron, and the manufacture of cardboard strips with holes. Often these works are performed with hand tools that does not provide neither the productivity nor quality.
Where will be introduced the trailer (see Fig.), developed plant facilities carpool trust Kuzbasstrans of Glavkuzbasstroy, will not require workers to dump taken on it lumber. A whole load of neat package “move out” on the ground because of the properties of the tipper trailer. This means that won’t affect the quality of the material brought will reduce the downtime of the car for unloading.
How soft and manageable fire “snakes” rolled in the hands of the rollers, they are so stubborn and hard to handle in the cold when cutting them on the measuring of the workpiece. Cutting methods — sawing with diamond discs, gas or plasma cutting or not give a smooth, does not require additional processing of the edge of the workpiece, or entail a significant waste of metal.
One of the major examination quality, which is a metal or alloy before you can become a responsible part of modern technology, the test of a test sample in tension. However, to determine what load it is able to withstand, you need to mount it in the testing machine. Existing methods or time-consuming, or complex. Innovators V. Kropotin and O. Ermolaev presented at the exhibition of IR-77 is a simple device and yet a very efficient clip (see Fig.), firmly gripping and holding the “pencil” test material.
Not only fitter or installer, but any technician knows to connect the two parts with the bolt, insert it through the hole, then throw the washer and finally screw and tighten the nut. As you can see, thus there is a double work: there is not only the Assembly of parts but also the Assembly of the bolt.
