L-shaped adjustment bracket 33 and material paving plate 34; the first L-shaped mounting plate 2 and the second L-shaped mounting plate 28 are installed on the top of the frame 1, and the two ends of the co...

Embodiment 2

[0049] The difference from Example 1 is that the rolling raw materials of this embodiment are metal powder and wire mesh plate, and the process of making metal powder and wire mesh plate into metal porous material is as follows: first, place the wire mesh plate on Below the hopper 9, lay the metal powder thickness to adjust the baffle plate 10 to a suitable height, add metal powder into the hopper 9, control the speed of the gear reduction motor 12 by adjusting the main frequency converter 6, turn on the switch 11, and start the rolling device. The metal mesh plate is rolled by the roll 47 to drive the metal powder to be continuously pulled out from the hopper 9, and the metal powder particles are evenly laid on the surface of the wire mesh plate. After the wire mesh plate and the metal powder composite plate enter the rolling area, they are rolled under the action of two rolls 47 . This embodiment can realize the rolling of metal powder particles of any size and metal mesh pl...

Embodiment 3

[0051] The difference from Embodiment 1 is that the integrated device of porous metal strip and powder composite rolling and sintering in this embodiment also includes a gas atomization spraying mechanism. see Figure 7 As shown, the aerosolized spraying mechanism includes a water tank 17, a pressure regulating valve 18, a quick-plug connector 35, an air pipe 36, a clamp 37, a nozzle 38, a safety relief valve 39 and a lateral mounting plate 40; the lateral mounting The plate 40 is fixed on the first mounting frame 14 and the second mounting frame 44 of the rolling device, the water tank 17 is fixed below the horizontal mounting plate 40 through a clamp 37, and a safety relief valve 39 is installed on the right end of the water tank 17 , to prevent excessive pressure in the water tank, the nozzle 38 is installed below the water tank 17, and is facing the upper surface of the material spreading plate 34 of the powder laying mechanism, and the quick-plug connector is installed ab...

Abstract

The invention discloses a metal porous strip and powder composite rolling and sintering integrated process and device. Powder laying, rolling, sintering and finished product roll collection are integrated, the characteristics that the technological process is short, raw materials are easy to obtain, the machining cost is low, and the production efficiency is high are achieved, and automatic and large-scale batch production is easy to achieve. According to the device, a gear reducer motor is adopted as a power source, the structure is compact, equipment can achieve light weight conveniently, the transmission efficiency is high, energy consumption is low, and maintenance is convenient. Meanwhile, a profile shifted gear is adopted for transmission, compared with chain wheel transmission, the structure of a transmission system is more compact, the rolling gap can be adjusted conveniently, and series products of different thicknesses can be rolled. Composite rolling of metal powder of different meshes and metal wire mesh strips of different meshes is achieved, the hole diameter and the hole gap of a metal porous material are controlled, and the multi-micropore metal porous material with different hole diameters, porosity, permeability, heat conductivity and structural strength is manufactured.

Description

technical field [0001] The invention relates to the technical field of manufacturing porous metal materials, in particular to an integrated process and device for composite rolling and sintering of porous metal strips and powder. Background technique [0002] Metal porous material is a functional and structural material with certain pore size and pores, good permeability, high temperature resistance, high stability, easy processing, and regeneration. Therefore, it is widely used in filtration, noise reduction, catalysis, heat exchange and other occasions. There are four types of common metal porous materials: foam metal materials, powder sintered porous materials, metal fiber felts and composite wire mesh materials. Foam metal materials have large porosity and low strength. When powder sintered porous materials are made into larger parts, cracks are easy to occur. Metal fiber mats are affected by the random distribution of fibers, and uneven pore sizes cause uneven air perm...
