It is generally accepted that a drill is the main tool DIY, hobbyists tinkering something with their hands for home, for family, as well as the main means of mechanization of labor-intensive processes in the creation of makeshift equipment. It is not surprising, because thanks to various auxiliary or additional devices drill can replace even some machinery. For example, a drilling machine, which can produce very simple equipment, published in the Hungarian magazine “Earmaster”.
Exhibitions amazingly beautiful decorative pieces of KAPA compete even with the amber jewelry—seafood and resinous prehistoric forests. Cap (in other words—influx) is a growth on the trunks of trees that represent an anomalous development of the wood. Once in the hands of a master, he is transformed into a work of art decorative art: original planters and flower vases, unusual dishes and bowls, pencil holders, ashtrays. All of these items look as if created by nature itself, and people only found these treasures in the woods, spying them in intricate swellings on the trunks (by the way, is detrimental to the tree).
The so-called unusual mechanism established at the Irkutsk industrial College for tightening heavily loaded threaded connections of large diameter. Anyone who has had to screw up the nut of the bolt, under the head of which is placed a rubber washer must necessarily have resorted to little tricks: when it’s getting on bad, just click on the head — it will dig into the rubber, the bolt will move forward and rotate the key will be much easier. Paradoxically, this principle was put to the Irkutsk innovators in the basis of the work of this mechanism. When tightened heavily loaded threaded connections of large diameter Jack allows you to stretch the bolt or stud within the elastic deformation that provides the subsequent free rotation of the nut.
Remember how in one of the Russian folk tales bear arc bent? Took two legs of the barrel at both ends and through the knee. For while it attempts, as we know, was not successful, note that to perform this operation, in modern technical language, it took him three working “element”: one rounding (knee) and two power (paws). The most modern devices for bending tubes and bars contain the same three elements. Usually they are mounted on a special table. There is a metal loop, which is inserted into one end of the pipe, a stationary roller — on it is bent, and the movable roller with the lever.
When machining on milling machines it is frequently necessary to install the item at a certain angle. An original device for this purpose was shown in NTTM-78 military innovators. This unique milling angle for the inclined fastening of machine parts. It consists of a base, a graduated sector and the movable hinge strap.
The denser the stack will be the builders of the concrete, the stronger will be the monolith. That is why in industrial and housing construction in the manufacture of precast concrete structures there is a need “compacted” cement mixture. At the Yaroslavl plant “Red lighthouse” for such purposes, developed an Electromechanical vibrator. In contrast to existing devices is not superficial, and deep submersible instrument: it can affect the entire thickness of the layer of concrete, compacting it well.
The method of circular broaching increasingly used for cutting the teeth of bevel gears, such as differential drive axle of the vehicle. The essence of the method of machining the workpiece cutting tool of a large diameter with radially arranged cutters. This technology is one of the most productive methods of manufacturing straight bevel.
The practical necessity of placing a furnace and a fireplace in a small area of the room led to the creation of a single “hybrid” structure of kamiloiki with a common Foundation and chimney. The specific location of its components contributes to the expansion of functionality and increase the heat output of such heating and cooking stoves (stove or fireplace), improving the environment of the room.
Among purchase toys that can move (ride, swim, run, fly, crawl), it is not easy to find such models that can be safely run in the apartment without fear that they’ll break, dropping to the floor, hurt themselves or broken in a collision with the wall or ceiling.
It’s like a magic trick: the metal part is placed on small size book, like a table and instantly welded to it — has no force can not budge it. How it works magnetic plate is designed for reliable and quick fastening of the workpiece during grinding, milling, and in conducting measuring and marking operations. Unlike other existing methods part clamping in a Vice or by using universal prefabricated devices — this device allows mounting auxiliary tool holders parts of even complex configurations.
