Abstract
The invention discloses a forcible tube expander, which comprises a stander. A plurality of expanding arbors which can slide on the stander are arranged on the stander; and a push mechanism used for pushing the expanding arbors to slide is arranged at the tails of the expanding arbors. The invention has the main point of the technical scheme that a clamping device which can clamp two ends of a tube of a heat exchanger to prevent the longitudinal shrinkage of the tube is arranged on the stander. The invention aims to overcome the following defects: in the prior art, the metal tubes of the heat exchanger can be longitudinally shrunk while being radially expanded, moreover, the shrunk size of each metal tube differs, as a result, the metal tubes of the heat exchanger are uneven, and the heat exchanger is shortened. The forcible tube expander can forcibly expand the heat exchanger but cannot shrink the heat exchanger, and can keep the size of the heat exchanger consistent.
Description
[technical field]
The present invention relates to a kind of electric tube expander.
[background technology]
Electric tube expander is the key equipment of a vitals in the heat exchanger air conditioner, and its principle is: utilize an expander roll, at the bloated ball of its end face setting greater than the copper pipe diameter.Under the effect of external force, the ball that expands swells copper pipe toward the copper pipe extruding, makes it closely to contact with fin, avoids producing loosening.At present, the electric tube expander on the market is when expanding the copper pipe of heat exchanger, and copper pipe all is to be in a kind of free state, when expand tube because the ball that expands greater than copper pipe, after copper pipe swells, will dwindle 3 ~ 4% naturally.Therefore, the heat exchanger of being produced under the production model in this often will slattern 3 ~ 4% raw material; And the employing high-power hydraulic system is wasted a large amount of electric power resources.
Along with improving constantly of civilization of human society degree, the epoch of economic develop rapidly and automated manufacturing arrive.Yet energy crisis is also more and more fiery thereupon, and especially raw material and electric waterpower resourses are in short supply day by day, and this will seriously affect the development of human being's production and even life.Following 10 years, China's sustainable development will face a series of severe challenge, should handle the problem of field long-term accumulation such as population, resource, environment well, solve the new problem that occurs in evolution again.How better the scientific and technical effect of performance provides stronger support and assurance for promoting China's sustainable development.In order to adapt to the needs that modernization science and technology is produced, further investigate and add great development and have the automaticity height, production efficiency production equipments high, energy-conserving and environment-protective are imperative.
[summary of the invention]
It is inconsistent to have the present invention seeks to overcome the size of understanding vertically contraction and every metal tube contraction when the metal tube of heat exchanger radially swells in the prior art, will cause the deficiency that metal tube is uneven and heat exchanger shortens of heat exchanger, provide a kind of heat exchanger pressure is swollen can not shrink the Forcible tube expander that keeps the heat exchanger size unanimity.
