The invention discloses an iron alloy-based composite hard alloy roller and a production method thereof. The iron alloy-based composite hard alloy roller is formed by pressing metal powder forming a hard alloy outer ring and metal powder forming an iron alloy inner ring through vacuum pressing and sintering, wherein the hard alloy outer ring consists of 69 to 71 percent of WC, 16 to 18 percent ofCo, 12 to 14 percent of Ni and 0.3 percent of mixed rare-earth powder; and the iron alloy inner ring consists of 20 to 25 percent of TiC, 0.3 percent of Ni, 2.5 to 3.5 percent of Cr, 8.1 to 9.1 percent of W, 0.4 percent of C, 2 to 3 percent of Mo and the balance of Fe. The iron alloy-based composite hard alloy roller has the characteristics of reasonable formula, synchronous vacuum pressing and sintering, energy conservation, solution of iron-based alloy oxidation problem, integrated fusion of diffusion interfaces, safe and reliable combination, high abrasive resistance, good surface quality,high forming precision and good heat cracking resistance and corrosion resistance.

The invention discloses an unburned brick manufacturing device. The unburned brick manufacturing device comprises a strong stirring machine, a forming and extruding machine and a roller machine, wherein the strong stirring machine is used for stirring, extruding and mixing aged raw materials; the forming and extruding machine is used for manufacturing the aged raw materials into unburned bricks after the aged raw materials are processed by the strong stirring machine; the roller machine is used for extruding and crushing the aged raw materials, and the aged raw materials can enter into the strong stirring machine again after the aged raw materials are extruded and crushed by the roller machine. According to the unburned brick manufacturing device disclosed by the invention, the roller machine, such as a strong roller machine, is added in front of the strong stirring machine, the lumpiness of stones can be controlled under 5 mm after the aged raw materials mixed with stones are extruded and crushed when the aged raw materials mixed with the stones pass through a crushing gap of the roller machine, and thus the normal operating of a latter process can be ensured; the aged raw materials are then extruded and mixed again by the strong stirring machine, thus the plasticity coefficient of the aged raw materials can be increased, not only can the unburned brick manufacturing device be protected, but also scrapped unburned bricks can be greatly reduced, and the output in one shift can be increased by 10-12%.

The invention relates to a preparation method of emulsion type pressure-sensitive adhesive. The manufacturing process of the pressure-sensitive adhesive emulsion of the present invention is by adding a cooling kettle. After the emulsion is kept warm in the reactor, the emulsion is directly placed in the cooling kettle to cool down, so that it is not necessary to carry out a long cooling process in the reactor. When the emulsion is cooled in the cooling kettle, the next pot of emulsion can be made in the reactor at the same time, which greatly shortens the process time and improves the shift output; at the same time, the cooling time and effect are greatly improved compared with the original one. In the process of putting the emulsion in the reaction kettle into the cooling kettle, the emulsion will dissipate a lot of heat when it comes into contact with the relatively low room temperature around, so the process of pouring the emulsion from the reaction kettle into the cooling kettle can reduce the temperature a lot, thus The later cooldown has been shortened.

The invention discloses a camshaft toothed wheel hub for an automobile engine and a powder metallurgy preparation method thereof. The method is carried out according to the following steps: step S101, batching; step S102, pressing and forming; step S103, blank sintering; step S104, finishing and processing; step S105, steam treatment; step S106, testing and packaging. The method of the present invention is connected in an orderly manner, with fewer procedures and a material utilization rate of more than 95%. The camshaft toothed wheel hub obtained by the method has less machining volume, high shift output and good consistency. It satisfies various performance requirements of the product. At the same time, the manufacturing cost of the product is reduced by 50%.
