Description
Technical field
The present invention relates to a kind of composite material and its manufacture craft, manufacturing device, especially a kind of super high speed elevator safety
Clamp wedge surface ceramic composite coating and its manufacture craft, manufacturing device.
Background technique
Elevator emergency brake process is a violent friction process, and braking time is short, and frictional force is big, for ultrahigh speed electricity
Ladder, in the case where the elevator brake time is constant, frictional force can be bigger, the temperature that moment generates can even reach 1000 DEG C with
On, this proposes high requirement for the high-temperature wearable damage performance of safety tongs voussoir, conventional security clamp voussoir mainly by carbon steel,
The materials such as cast iron, steel alloy manufacture, and in high speed braking process, are enough with high temperature caused by guide rail severe friction by it
Softening, so that safety tongs be made to fail, elevator speed is out of control, will lead to serious casualties and equipment is lost.
The hardness of ceramic material is high, fusing point is high, is coated onto piece surface using laser melting and coating technique, can significantly improve
The high temperature abrasion resistance of part will also have good punching however, super high speed elevator safety tongs voussoir not only requires high temperature wear resistant
Toughness is hit, this is because the movement of super high speed elevator safety tongs will cause guide rail deformation, to cause safety tongs voussoir and guide rail hair
Raw to hit, since ceramic material fusing point is high, mutual wellability is poor, and directlying adopt ceramic powders is laser cladding of material,
Cladding layer is easy to produce the defects of micro-crack, stomata, will significantly reduce the impact flexibility of coating, and coating is easy cracking, is crushed, leads
Cause brake fade.
Summary of the invention
The shortcomings that the invention solves the above-mentioned prior arts provides one kind on super high speed elevator safety tongs voussoir rubbing surface

The working principle of the safe voussoir surface ceramic composite coating manufacturing device of super high speed elevator in the present invention: first peace
Full pincers 9 are placed on the inclined support surface 2-3a of supporting block 2-3, safety tongs 9 are pushed, until safety tongs 9 leans against at the block 2-4 that keeps to the side
Until, it then, turns handle bolt 2-7 and safety tongs 9 is pressed at right snap-gauge 2-6 (as shown in Figure 5), then, starting is super
Sonic transducer 6 simultaneously makes plate 2-2 generate high-frequency vibration, so that safety tongs voussoir 9-1 generates high-frequency vibration, then,
The mixed-powder material of input FeV powder, graphite powder, Ni powder, ceramic particle composition, mixed-powder material pass through in feed end 3-1b
Discharging gap a falling on the top of safety tongs voussoir 9-1 at the uniform velocity on a small quantity, falls to the mixing on the top surface safety tongs voussoir 9-1
Dusty material is vibrated by ultrasonic transducer 6 and is uniformly spread out, and at the same time, utilizes high temperature caused by industrial laser 3-2
Laser beam carries out scorification to mixed-powder material and makes safety tongs voussoir 9-1 that molten also occur, to make mixed-powder material
It is completely fused together with the surface safety tongs voussoir 9-1 by laser melting and coating technique, at the same time, utilizes six shaft mechanical arms 4
It is constantly mobile to drive mixed-powder material discharging machining mechanism 3, so that the entire surface safety tongs voussoir 9-1 is processed,
From first of mixed-powder Material reinforcement coating to second mixed-powder Material reinforcement coating again to strengthening layer, finally, each strong
Change layer heap product, and then is combined into ceramic composite coating 9-2 (i.e. increasing material layer), this mode, high-efficient, precision height, firmness height,
It is worthy of popularization.
Although the present invention has been illustrated and described with reference to preferred embodiments, this profession ordinary skill
Personnel are it is to be appreciated that within the scope of the claims, can make various variation in form and details.
