Of all the plumbing tools in the “conservative” design remained still, probably only a hammer. However, the innovators of the production Association Zhdanovtyazhmash found the opportunity to improve it. They created multi-purpose bench hammer. It can rightly be called a harvester — informed so many unusual functions, it can now make thanks to the extra built-in details.UNIVERSAL STRAP
Rationalization proposal Lyubertsy student of secondary school № 42 of Konstantin Shishkin. If you need to turn on a lathe a few identical parts rather complicated configuration, it makes sense to use a universal strap-holder which can be mounted a set of cutters. It is made very simply is a steel bar with a groove Read more…
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”.
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 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.
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.
Small lathe for wood can actually be very simple. The overall layout and main components are known is a base with rails, front and rear headstock; the first is integral with the frame, the second movable in the guide; on the front of the headstock spindle is mounted with the actuator on the rear — support center. In fact, the feature of the machine, its simplicity and the possibility of manufacturing craftsman are determined by the design of main components.
Try to cut multiple identical workpieces on a lathe. How many times have to use a caliper! But if you make for his Studio, universal focus, the workpiece will turn out one in one — and without the frequent use of any measuring tool. Arranged focus just. In the tool post of the lathe near the cutter secured using a steel strap with a screw hole, in which is wrapped a screw. He will serve as a measuring stop is enough to set it to the desired size and fix it with the locknut. Now, to cut the workpiece of a given size, the rod from the holder just forward of the machine until it stops at the bolt head.
Vocational school graduates, finishing school, to protect diploma. They are often self-development: engineering and manufacturing of complex parts, assemblies, or fixtures. Cartridge-machine — theme of the graduation project of the former student of vocational school № 40, now training master M. Arkhangelsk.
Usually a heavy box, container or pallet with a load attaching to a lifting mechanism using four ropes-slings; lumber, pipe of large diameter it is possible to raise two. If you overwhelm sling loop-the loop, the normal load will rise and it one. Well, if you want to move, say, heavy sheet metal?
