Description
Technical field
The invention belongs to the explosive processing field of metal material, in particular to the installation of a kind of compound plate and base base explosive welding
Structure and its method, the explosive processing suitable for different metal material.
Background technique
Explosive welding (also referred to as " Explosion composite ") is the method for carrying out inter metallic bond as energy using explosive charge, it is utilized
The detonation of explosive makes the metal surface placed up and down that high speed inclined impact occur, and the plastic deformation of metal is generated on faying face,
To which they be welded to form varied explosive welding material.Under the premise of meeting specified conditions, compound plate and substrate
Or base base could effectively weld together, this specified conditions mainly include explosive kind, detonation mode, fire point position,
Plate spacing, explosive payload etc., when usually realization effectively being welded between used explosive kind, detonation mode, fire point position, plate
Summation away from parameters such as, explosive payloads is referred to as " window " of explosive welding.Same metal can not only be welded on one by explosive welding
It rises, the unweldable dissimilar metals of traditional welding method can also be welded together, formed such as steel --- aluminium, steel ---
Copper, copper --- aluminium, steel --- lead, steel --- composite materials such as titanium.Since bimetallic, polymetallic composite material are removed with Dan Jin
Outside the fundamental characteristics for belonging to material, functionally also there are other unrivaled characteristics of monometallic material, therefore, Explosion composite
Material has been widely used in many fields such as chemical industry, petroleum, water conservancy, printing and dyeing, electronics, has and closes wealthy market application prospect.Just
Stainless steel --- for straight carbon steel composite material, being used as market and hotel balustrade, not only intensity is high, and beautiful beautiful；With
Making the steel sash railing of residential building, not only intensity is high and corrosion-resistant；As urban road lamp stand, not only intensity height, beauty are floated
It is bright and cheap；Not only intensity is high, corrosion-resistant and at low cost for reaction kettle as chemical industry.
The method of metal material explosive welding mainly has parallel method and two kinds of preset angle configuration.Currently, domestic explosive clad plate master
To be that plate --- plate is compound, compound plate thickness in 10mm or less, substrate thickness in 50mm hereinafter, the difficulty of explosive welding relatively
Small, production efficiency is relatively low.Since slab and blank welding construction store doses are larger, production technology is complex, once it is quick-fried
Fried welding will unsuccessfully will cause very huge economic loss, and therefore, the country there is no producer to carry out the industrialization that slab and blank weld
Work, research in this regard are also few.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of multiple for the deficiency of existing explosion welding technique
The mounting structure and its method of plate and base base explosive welding avoid compression stress wave from being reflected into tensile stress wave at the scope of freedom and go out
Phenomena such as now peeling off and be broken can reduce or eliminate the boundary effect of explosive welding, improve the quality of explosive welding, moreover it is possible to reduce
Supplies consumption in blast process.
The technical solution that the present invention solves the above technical problem is:
A kind of mounting structure of compound plate and base base explosive welding, including the base base above cheating that explodes is arranged in, is arranged in parallel
The explosive frame of compound plate and the interior filling explosive being bonded with it being arranged in above compound plate above base base, the detonation of explosive frame
End is equipped with igniting primer；One piece is welded along the outwardly extending front guide of compound plate length direction, described multiple in the initiation ends of compound plate
The end of plate welds one piece along the outwardly extending back guide of compound plate length direction, respectively welds in the two sides of the compound plate width direction
One piece along the outwardly extending wing plate of compound plate width direction；In base base one end corresponding with compound plate end and base base width direction
Two sides are each provided with the blank being bonded with base base, and the blank of the fitting avoids compression stress wave from being reflected into stretching at the scope of freedom answering
There is phenomena such as peeling off and being broken in Reeb, issuable boundary effect when reducing or eliminating explosive welding.
A kind of method of compound plate and base base explosive welding will be handled in outdoor or underground explosion place by polishing
Compound plate to be welded and base base installed by the above mounting structure, explosive appropriate is loaded in explosive frame, by igniting primer
It is placed in one end of explosive frame, compound plate and base base realize explosive welding after detonation, form explosive composite material.
The technical solution that the present invention further limits is:
The mounting structure of compound plate above-mentioned and base base explosive welding, the length and width of base base are L and B, and the length and width of compound plate are L
+ δ and B+ δ, δ are 4~10mm, and the length of front guide is m, and m is 300~600mm, and the length of back guide is n, n is 100~
300mm。
The mounting structure of aforementioned compound plate and base base explosive welding, wherein front guide is equal with the width of compound plate with back guide.
The mounting structure of aforementioned compound plate and base base explosive welding, wherein explosion hole is sand pit.
The beneficial effects of the present invention are: the risk that (1) the avoidable large-area sheet base explosive welding of the present invention fails, to subtract
The consumption of various types of materials during few explosive welding.(2) the present invention welds one piece of front guide, end welding in the initiation ends of compound plate
One block of wing plate is respectively welded in one piece of back guide, two sides, places some discarded bases against the end of base base and side when in-site installation
Material can reduce or eliminate the boundary effect of explosive welding, improve the quality of explosive welding, and technological operation is simple.(3) this hair is used
The large area compound plate and base explosive composite material of bright formation, can be obtained the composite material of different-thickness requirement after rolling.(4) originally
Invention carries out explosive welding work using plate and base, can increase substantially production efficiency and reduce production cost.
