Abstract
The utility model provides a copper bar tooling used for spot welding of a stainless steel vehicle roof, comprising an alloy copper plate, a substrate material, an arc-shaped vertical plate, a pin seat, a central pin, a positioning block, a clamp and a clamp seat. The copper bar tooling is characterized in that the alloy copper plate and the substrate material are compounded into an integrated composite copper plate. In the utility model, the alloy copper plate is compounded with the substrate material into a whole, the screw connection is replaced and the copper cap covered above the screw is canceled simultaneously, therefore, the sinking problem of the copper cap is avoided, the service life of the tooling is prolonged and the cost of the tooling is reduced. When the copper bar with the same specification and dimension is produced, compared with the prior art, the manufacturing cost can be reduced by more than 20%, the service life of the copper bar can be prolonged by more than 5 times simultaneously, the effect on the product quality due to the sinking of the copper cap is solved, and the product quality is improved.
Description
Technical field
The utility model relates to a kind of stainless steel roof and makes frock, especially relates to a kind of spot welding copper bar frock.
Background technology
In the modern mechanical manufacturing field, the roof steel construction of passenger vehicle is designed to arc, and for guaranteeing the roof arc, the alloy copper coin with 15mm thickness when making the roof spot welding copper bar passes through a large amount of skivings, machinery bends and forms required arc in the production process; Adopt the alloy copper coin to be connected tightening technology with base material by screw, the copper cap reaches the sufacing requirement by skiving on the screw upper cover.In this process technology, the equipment spot-wedling electrode carries out spot welding, pressurization to copper cap position for a long time, causes copper cap depression to be sunk, and has a strong impact on the roof point quality, shortens frock service life, causes the waste of a large amount of alloy copper coins, production time, manpower.
The utility model content
The purpose of this utility model provides a kind of new stainless steel roof spot welding copper bar frock, reduces alloy copper coin skiving thickness in process greatly, saves time, manpower and financial resources.The spot welding depression problem of having avoided screw to connect simultaneously bringing, thus effectively guarantee point quality and prolonged copper bar frock service life.
For achieving the above object, the utility model provides a kind of stainless steel roof spot welding copper bar frock, comprise alloy copper coin, base material, arc riser, key seat, centrepin, locating piece, clamp and clamp seat, it is characterized in that: alloy copper coin and the base material compound copper coin of formula that is combined into one.
The utility model alloy copper coin and base material are combined into one, and have replaced the screw connection, have cancelled the copper cap of adding a cover on screw simultaneously, thereby have avoided copper cap depression sinking problem, prolonged frock service life, reduced the frock cost.The copper bar of producing the same size size can reduce manufacturing cost more than 20% than prior art, prolongs copper bar service life simultaneously more than 5 times, has solved because of the influence of copper cap depression to product quality, improves the quality of products.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
With reference to accompanying drawing, the utility model comprises that securing member, alloy copper coin are bell metal sheet material, adopt Cr0 by alloy copper coin and base material be combined into one compound copper coin 1, arc riser 2, key seat 3, centrepin 4, locating piece 5, clamp and the clamp seat 6,7th of formula
5Cu, Cr content be greater than 0.5%, and after Technology for Heating Processing, its performance will satisfy the requirement of making electrode material, and hardness is greater than HB110, and conductance is greater than 60%, long 2800+300mm * wide 500+60mm * high 8mm; Base material adopts common Q 235 steel plates.The thickness of steel plate is 2～3 times of bell metal sheet metal thickness, by explosion welding method bell metal sheet material and two kinds of foreign materials of steel plate are welded into one, guarantee explosive welding (EW) faying face 〉=95%, can adopt lossless detection method to test, adopt heavy orthopedic equipment to carry out orthopedic to composite plate, with machining process composite plate is cut into bar shaped, and adopt mechanical means that composite plate is carried out preformed, after the preformed to composite board periphery machining, the bell metal plate surface carries out polishing, surface roughness is not more than Ra3.2, and must not there be any processing tool marks on the surface through polishing.
