Abstract

The invention relates to a pipe expander for a condenser. The pipe expander comprises a rack, wherein a fixed rod is mounted on the rack; the upper end of the fixed rod is connected with a mounting plate; a cover plate and a guide plate which are arranged on the fixed rod in a sleeved manner through a guide sleeve are arranged below the mounting plate; a drive mechanism for driving the cover plate to move up and down is arranged on the mounting plate; a plurality of pipe expanding long rods are connected on the lower end surface of the cover plate; a plurality of pressure sleeves are fixedly arranged on the lower end surface of the guide plate; a limiting rod positioned below the guide plate is further arranged on the rack; the pipe expanding long rods are connected with the cover plate through a fixing device; guide holes adaptive to the pipe expanding long rods are formed in the guide plate; a clamping device used for fixing the condenser is arranged on the rack; and the clamping device is positioned below the guide plate. The pipe expander has the characteristics of being simple in structure, suitable for a small condenser, high in precision, high in production efficiency and the like.

Description

technical field

[0001] The invention relates to the technical field of condenser manufacturing equipment, in particular to a tube expander for a condenser. Background technique

[0002] The tube expander is a machine used to expand the diameter of many heat exchanger tubes placed in the heat sink, so that they can be tightly combined with the heat sink to avoid loosening and increase the thermal conductivity of the heat exchanger. Existing tube expanders are used for large condensing tubes, but there is no corresponding equipment for some small condensing tubes. If the previous tube expanders are used to expand small condensing tubes, it will be overkill. , which has the effect of getting twice the result with half the effort, which not only increases the cost, but also reduces the production efficiency; even if there is a tube expander for small condensing tubes, there are still low production efficiency, low degree of automation, troublesome debugging, and workload Large,...
