Description

The disadvantages of the conventional technological solution are low (the yield due to insufficient pressure intensification, the value of which (less than 1 kg / cm) is chosen on the basis of the integrity of the material, and the material in the matrix is reached and the mass of temperature and temperature and temperature and temperature and temperature and temperature and temperature and temperature and temperature and temperature and temperature and temperature and temperature will be attained; However, this pressure is effective only at the sintering temperature. However, with more than 1 and 3 TeMineipaTyipax effects, more pressure is observed, which in an important yciipio cTBe does not provide The aim of the invention is to increase P1rc1iz1v101d1ntelivosti. The goal is achieved due to the fact that, in the device, the ST1Be irGim is made of a fernite metal in 1c, and the core of the core has been applied to the pattern, the object is already in use. , lyrichem lr, izhim is equipped with an okoy and is installed with the possibility of lOiceBOTO in the center: mesh, e1n; and, while the coil is made of two sections and connected to one of the sections with the current tree. Such an implementation of the device permits one to impregnate the Spaking process with ineipe pressure, the magnitude of which is, maximally at low temperatures. Gradually decreases to, I m1 H1 The maximum value of trn is apecann temperature. This is especially important with high-speed heating methods (e.g., high-frequency currents), when the duration of effective stress, and pressure is sharply reduced. In the drawing shows a device for applying ground fytiy lz metal-metal powders In T0 | The device contains a source and a heat a /, a support that has been released in the form of a non-metallic matrix 2, which interacts with a layer of powder deposited on the face surface of the part, and is mounted on the housing 3 of the device. Inside the casing 5 placed reel, made up of two sections 4 m 5 serdechnnkom 6 of ferromagnetic (the material. Oerdechvik 6 integrated with the workpiece porredstvOM 7 serves clamp. The device operates sleduYuSchShM oi6pazom. The item coated with its r1abochuyu poiBOpxHiOicTb layer of powder is installed in ssevom hole 1se1rd.blazer 6 and fixes sk0 | battle 7. Then 1core11K is placed inside the 4 coils section | And electroad-pin and non-metallic matrix 2 so that noBeipxHiOCTb parts work With its working surface applied and the surface of the powder layer apera the forming part of the matrix. After the segmentation 4 and 5; the coil of the Elekirom Pnita transmits current. The electric energy, converted into matte, pulls the core, prepressing the powder layer to the forming part of the matrix 2. Then turn on the source of heating /, in the zone of action IKOTOporo are located (the barrel surface of the part, the layer of the parachute and (the upper part of the core 6. Simultaneously the interrupter is turned on (not shown)), which disconnects the section 4 of the cathode in turn with a certain frequency. Periodic disconnection of ONE of the Katush | KI sections at 1 WTO.LYABLE ONLY KEY. Another section allows changing the output of the coil and the elec- tro; mapnita. As a result, the magnitude of the force due to a stepwise change as a result of the sarchetnika is reduced first and a. then it reaches its current value in each box of iC oscillations decaying and | mplitud0 and, conversely, (P; p, and cooling the core, the magnitude of the force and the amplitude of its oscillations increases. With a sintering temperature reached 1000T1 | Disable 1 on preheat. In order to prevent a decrease in the density of the coating, resulting from the effect of an elastic aftereffect, the layer is kept under a progressively increasing, pulsating pressure during the cooling process, 17 | and prerivatel disconnected, the item is removed and subjected to subsequent neobhodimo1sti ter1M10Obra; Botko Pradlo:. zhan1ns1e device allows to receive the following preimzschestva: increase pro) voditelno1st coating process, that exhibit a reduction in the duration vyderlski lie temperature spykani 30-60%; to increase the hardness and DURABILITY of coatings by 16–20%, since the heating of 1 | | sotslotnye coatings is carried out at a low temperature, which contributes to maintaining the high quality structure of the powder; prevent (displacing the material of the coating on non-working surfaces of the part, and consequently, reduce the material consumption and the volume of the subsequent mechanical treatment; safety of the material | the value of the pressure applied depending on the temperature | and the strength properties of the coating during sintering. Formula 1 A device for applying metal powders to end surfaces of parts, including iKopnyc, a heating source, a support and a clamp, characterized in that, in order to increase the productivity and process prizhlm made of ferromagnetic 1M Container material to form cores of the electromagnets, katuschka

KOTxDiporo is installed in the housing of the coaciale irizhimu, and the clip is clamped with a bracket and installed with the possibility of an axial movement.
