Specific embodiment:
The present invention will be further explained below with reference to the attached drawings:
As shown in Fig. 1 to Figure 18, the composite pad includes steel skeleton and ceramic matrix two parts composition.
The steel skeleton avoids strip liner from occurring when bearing load disconnected for the arrying main body as composite pad
It splits.Steel skeleton selects heat resisting steel material, after being cut into a strip using sheet metal, stamps out to side and carrys out a series of ramuscules
Pawl, to strengthen the bonding strength with ceramic matrix.
The ceramic matrix it is fully wrapped around live steel skeleton, oxidation when avoiding its firing, and the shape master as composite pad
Body forms the pad profile that front has micro groove.Common kaolin of raw material selection general pad of ceramic matrix etc. is viscous
Local soil type point, is pressed into blank in mold together with steel skeleton, then forms by a firing in heating furnace.
The manufacturing process of the composite pad is summarized as follows: the first step, by cutting and Sheet Metal Forming Technology, by heat resisting steel material
Sheet metal be processed into steel skeleton；Using clay compositions such as the common kaolin of general pad as the ceramic raw material of liner base,
Dispensing in advance and mix it is rear spare.Second step adds a small amount of ceramic raw material, such as Fig. 3, then with flat for the first time in die for blank
Raw material powder is pressed into a thin layer by pressure head, as the bottom surface of ceramic matrix, such as Fig. 4.Steel skeleton is placed on blank by third step
It is then secondary to add more ceramic raw material, such as Fig. 6 such as Fig. 5 on the ceramic matrix bottom surface pressed in mold.4th step, benefit
Raw material powder is pressed into an entirety together with steel skeleton, forms the inside steel by the convex pressure head that arc dimpling is had with front
The composite pad blank of package ceramic matrix, such as Fig. 7 outside skeleton.5th step, in normal reheating furnace, according to common welding lining
The burning process of pad forms by a firing composite pad blank.
The installs fixture includes: 2 annular magnets, 2 magnet pad supports, 2 washers, 1 handle brackets, 1 elasticity
Tabletting, 1 liner deck, 4 screws, installs fixture utilize magnetic absorption principle, and composite pad is fixed on steel plate to be welded.
For the annular magnet for being adsorbed on steel plate to be welded, annular magnet selects high temperature resistant strong magnets material, among annular magnet
Hole is fixed for penetrating magnet pad support.The magnet pad support is for stationary annular magnet and avoids annular magnet and steel plate to be welded
Directly collide with.Magnet pad support is that a disk of thin wall is welded with a small column, and small column top threading is used for
It is connect with handle brackets threaded hole.
Handle of the handle brackets as manual placement and fixture for separating curves saddle type by stock, adds after the overstriking of both ends
Work threaded hole, for being connect with magnet pad support external screw thread.The elastic pressuring plate has certain elasticity, for applying to intermediate liner
Add and is centainly adjacent to pressure.Elastic pressuring plate is cut by sheet metal, and intermediate 4 apertures are connected in one by screw and liner deck
It rises, both ends large hole connects together for penetrating magnet pad support with handle brackets both ends.The liner deck is wide greater than liner
The cuboid of degree, lower part fluting are processed minor thread hole, are connect by screw with elastic pressuring plate for blocking liner, top.
After each component assembling of mounting fixture, the height cooperation with composite pad will guarantee: when fixed composite pad, bullet
Property tabletting among be slightly above both ends, thus apply certain elastic pressure to composite pad, be allowed to be adjacent to steel plate to be welded.
The mounting fixture is in use, first put several groups of composite pads along divided edge of steel plate position to be welded cloth well；It again will peace
The liner deck of tool of being loaded is stuck in the ends of two groups of composite pads, is allowed to fix and be adjacent on steel plate to be welded；Then it is welded
Connect operation；Postwelding separates mounting fixture, and used composite pad is also just split away off.
