Problems solved by technology

But how to firmly combine the copper tube and magnesium alloy is the key to making this kind of radiator. Since the hot water or steam in the tube has a certain pressure, especially for heating in high-rise buildings, once the combination of magnesium alloy and copper is unreliable , it is prone to explosive phenomena and cause damage to the radiator and accidents

Embodiment Construction

[0011] The present invention will be further described by making a magnesium alloy copper die-cast composite column airfoil convection radiator with a specification of 500 mm.

[0012] A magnesium alloy copper die-casting compound column airfoil convection radiator die-casting process has the following process steps:

[0013] a. Make inserts; ①Saw long copper pipe sections with a diameter of Φ16mm and a wall thickness of 1mm, each section is 500mm long, and bend both ends of the copper pipe section to the same side; ②On the same side of the pipe wall of the pipe joint Drill two Φ16m copper pipe connection holes, the copper pipe connection holes communicate with the inner hole of the pipe joint; ③ insert the two ends of the bent copper pipe into the copper pipe connection holes of the pipe joint, and connect them Welded connections, made into inserts;

[0014] b. Die-casting; ①The insert fixing device of the mold is the clamps set at intervals on the static mold corresponding ...

Abstract

The invention relates to the technical field of die-casting technology, in particular to a die-casting process for a magnesium alloy copper die-casting compound column airfoil convective radiator, which has the following process steps: a. making inserts; b. die-casting; c. demolding. The magnesium alloy copper die-casting composite column airfoil convection radiator prepared by the present invention has a magnesium alloy body, which is light in weight, good in strength, good in decoration and low in cost; the built-in water channel insert is made of copper material, and its corrosion resistance is good. Long service life; magnesium alloy is formed in a die-casting mold in a high-temperature liquid state, with high material density and no welding processing points on the surface, which is durable; the built-in water channel insert and the body are die-casted at one time, and the insert has high strength. Magnesium alloy and copper The combination is reliable.

Description

Technical field [0001] The invention relates to the technical field of die-casting technology, in particular to a die-casting technology for a magnesium alloy copper die-casting composite column airfoil convective radiator. Background technique [0002] In most areas of northern my country, a heating system consisting of radiators, boiler bodies, piping systems, and high-temperature hot water heat medium (or steam) is generally used to solve people's heating problems and fight against severe cold. As the radiator of the terminal device of the heating system, there are traditionally cast iron radiators and steel radiators. Cast iron radiators are notoriously bulky and poor in appearance, so steel radiators have been used instead of cast iron radiators. However, the steel radiator has poor resistance to oxygen corrosion. Since the urban heating system in our country is mainly based on centralized heating, many heating system designs use atmospheric boilers for direct heating...
