Abstract
A kind of heat exchanger inlet and outlet pipe and the fixed riveting device of water chamber, including formed punch, conduit and riveter, specific structure and connection relationship are as follows: the hole of conduit is provided with formed punch that can be up and down along conduit axis direction, conduit by pin with can be connect along the riveter that pin axle center is freely rotated.It is fixed using the riveting that the utility model is able to solve closed loop water chamber and inlet/outlet pipe, ensures product appearance and quality after inlet/outlet pipe and closed loop water chamber are fixed, and easy to operate, equipment input cost is low.
Description
Technical field
The utility model relates to a kind of riveting device being mechanically fixed, especially a kind of heat exchanger inlet and outlet pipe and water chamber are solid
Determine riveting device.
Background technique
The heat exchanger inlet and outlet pipe fixed form of closed loop water chamber structure mainly uses outside argon arc welding spot welding inlet/outlet pipe at present
Root is connected and fixed with water chamber, and feature is easy to operate, the disadvantage is that solder joint is exposed to product surface, influences product appearance and matter
Amount, or friction welding (FW), laser welding process are used, advantage is that product appearance quality is good, but equipment input cost is high.
Summary of the invention
The purpose of the utility model is to provide a kind of heat exchanger inlet and outlet pipes and the fixed riveting device of water chamber, can apply
The riveting of closed loop water chamber and inlet/outlet pipe, solving closed loop water chamber and inlet/outlet pipe can not ask using conventional riveting technique is fixed
Topic.
The technical scheme adopted by the utility model is a kind of heat exchanger inlet and outlet pipe and the fixed riveting device of water chamber, packet
Include formed punch, conduit and riveter, specific structure and connection relationship are as follows: the hole of conduit is provided with can be living up and down along conduit axis direction
Dynamic formed punch, conduit by pin with can be connect along the riveter that pin axle center is freely rotated.
The punch end face is cone.
The riveter is equipped with the inclined-plane in the same direction with formed punch circular conical surface angle.
After inlet/outlet pipe and closed loop water chamber assemble, conduit is inserted in inlet/outlet pipe, formed punch moves down, formed punch circular cone
The outside riveting inlet/outlet pipe inner wall of riveter and closed loop water chamber cooperate section position behind face and riveter contact of incline plane, and inlet/outlet pipe close-fitting is solid
After being scheduled on closed loop water chamber, formed punch exits reset, and conduit can be exited out of inlet/outlet pipe at this time, completes inlet/outlet pipe and closed loop water
The riveting of room is fixed.
The protrusion effect of the utility model is:
Closed loop water chamber and inlet/outlet pipe are able to solve using the fixed bad order of spot-welding technology or friction welding (FW), Laser Welding
The expensive problem of process equipment investment is connect, used in the riveting of closed loop water chamber and inlet/outlet pipe, has easy to operate, frock cost is low
The advantages of.
Detailed description of the invention
Fig. 1 is the structural profile illustration of heat exchanger inlet and outlet pipe described in the utility model and the fixed riveting device of water chamber.
Fig. 2 is the riveting working section principle of heat exchanger inlet and outlet pipe described in the utility model and the fixed riveting device of water chamber
Figure.
Fig. 3 is heat exchanger inlet and outlet pipe described in the utility model and the fixed riveting device inlet/outlet pipe of water chamber and closed loop water chamber
Diagrammatic cross-section after riveting is fixed.
In the figure, it is marked as formed punch 1, conduit 2, riveter 3, closed loop water chamber 4, inlet/outlet pipe 5.
Specific embodiment
The utility model will be further described with reference to the accompanying drawings and examples.
Comparative diagram 1 to Fig. 3, heat exchanger inlet and outlet pipe described in the utility model and water chamber fixes riveting device, including formed punch
1, conduit 2 and riveter 3.Specific structure and connection relationship are as follows: formed punch 1 is mounted in 2 hole of conduit, and formed punch 1 can be along the axis of conduit 2
Direction is up and down, and conduit 2 is connect with riveter 3 using pin feature, and riveter 3 can be freely rotated along pin axle center.
1 end face of formed punch is cone.
The riveter 3 is equipped with the inclined-plane in the same direction with 1 circular conical surface angle of formed punch.
The working principle of heat exchanger inlet and outlet pipe described in the utility model and the fixed riveting device of water chamber:
After inlet/outlet pipe 5 and closed loop water chamber 4 assemble, conduit 2 is inserted in inlet/outlet pipe 5, formed punch 1 moves down, punching
Outside 5 inner wall of riveting inlet/outlet pipe of riveter 3 and closed loop water chamber 4 cooperate section position after first 1 circular conical surface and 3 contact of incline plane of riveter, into
After 5 close-fitting of outlet is fixed on closed loop water chamber 4, formed punch 1 exits reset, and conduit 2 can be exited out of inlet/outlet pipe 5 at this time, complete
It is fixed at inlet/outlet pipe 5 and the riveting of closed loop water chamber 4.
