Description
Technical field
The present invention relates to a kind of weld jig for exhaust system muffler clam shell type end cone, belong to welding tool setup
Technical field.
Background technology
Nowadays in automobile industry, the hot junction catalyst encapsulation both ends end cone form of passenger car is mainly whole including punched
Body formula end cone, cylinder spun type end cone and clam shell type welding end cone, and because chassis structure becomes increasingly complex, punched end
In the case that cone can not meet end cone angle, clam shell type welding end cone is more widely applied in actual design production, together
When propose to homogeneity of product after welding and the requirements at the higher level of qualification rate.
Clam shell type welding tooling mainly uses the following two kinds scheme at present：First, it is fixed upper and lower clam shell holotype monoblock type to be wrapped up
Position, major control clam shell profile and both ends port, have upper lower impressions to press, and alignment pin is inserted at clam shell port.This scheme
Defect：First, upper and lower clam shell holotype positioning, high is required to clam shell accessory size, upper and lower mould is produced and processed require it is high, it is necessary to
A large amount of process times, follow-up pincers worker grinding requires high, time-consuming longer, while requires stability and product piece mould to product long period
The abrasion of tool has higher requirements, more difficult reparation after welding tooling abrasion, and cost is very big；Workpiece is not in place when piece installing operates and play
More apparent, percent defective is higher, and resilience and the transport of punching press clam shell deform, and can influence production stability.
2nd, this scheme compares the first scheme, removes the positioning of clam shell holotype, only carries out locating clip to clam shell both ends straightway
Tightly, driven using locking pliers with type compact heap, vertical depression, it is steady to ensure that port size clamps with clam shell for alignment pin in clam shell port
It is fixed.The defects of this scheme：First, piece installing needs operator to see whether in place, clam shell misalignment to be easily caused, among housing
Do not control, welding clam shell both ends weld seam is longer, and heat is larger, makes housing distortion serious, and sensor is by housing such as on clam shell
Deformation effect, position deviation is larger, can not ensure overall relative size, follow-up welding is had a great influence, scrappage is higher.
