Problems solved by technology

This kind of products used to be directly drawn from the copper tube, and then bent. Because the pipeline itself is long and the diameter of the copper tube is large, the copper tube with a large diameter is very hard and very hard when the air conditioner is assembled and the whole machine is installed later. Difficult to assemble. At the same time, copper pipes are prone to wrinkling and dead bends. At present, the existing pipeline parts have a single processing form and a variety of process combinations. Multiple solder joints and external parts are required, which not only increases the cost but also buryes hidden dangers. , has a great influence on the performance of the air conditioner

Embodiment 1

[0018] Embodiment 1: under the premise of prior art, at first copper tube is processed into bellows (4), as figure 1 As shown, the corrugated wheel and other auxiliary equipment are combined, and the processing length is automatically controlled by the travel switch. Finally, qualified corrugated pipe products can be produced. The position of the pulling table is determined, and then the bending is carried out through the mold (3). Pull out the platform (2) at the positioning point. The platform (2) is drilled by positioning a hole of φ3.2, turning the hole with an inner diameter of φ6.5 and a platform height of 2.5mm, and then adjusting the hole to an inner diameter of φ6.5 and a platform height of 2.5 mm. 2mm holes. Repeat the bending 140 degrees again, position the pulling platform (2), and bend 130 degrees for the third time, and position the pulling platform (2). Then the product is annealed, and the thread bending is treated emphatically to ensure the bending range and ...

Embodiment 2

[0019] Embodiment 2: First, the copper pipe is processed into a corrugated pipe (4), which is combined by a corrugated wheel and other auxiliary equipment, and the processing length is automatically controlled by a travel switch. Finally, qualified corrugated pipe products can be produced, and then the dial is determined. Determine the position of the pulling platform, and then bend (3) through a special mold, and pull the platform (2) at the positioning point. The pulling platform (2) is to punch a hole of φ4.0 through positioning, and the inner diameter of the turning is φ7.0 , a hole with a platform height of 3mm, and then the calibration hole is a hole with an inner diameter of φ7.0 and a platform height of 2.5mm. Repeat the bending 150 degrees again, position the pulling platform (2), and bend 140 degrees for the third time, and position the pulling platform (2). Then the product is annealed, and the thread bending is treated emphatically to ensure the bending range and b...

Abstract

The invention provides a novel corrugated gas collecting pipeline member, wherein a section of copper pipe is machined into a corrugated pipe, and the copper pipe can be freely bent back and forth during air-conditioner assembly and complete set installation, and therefore the problems of corrugation and dead turn during installation are solved. Meanwhile, a drawing station, a sealing cap, bending, the corrugated pipe, welding and the like are combined together through accurate calculation, smart design and exquisite technologies, therefore the practicability of the product is increased; in addition, no new equipment is increased under the conventional production conditions, therefore product diversification and high return with small investment are realized.

Description

technical field [0001] The invention belongs to a production method of a corrugated air-collecting pipe piece for air conditioners. Background technique [0002] The main function of the gas collecting pipe in the air conditioner is to collect all the gas in the evaporator into the gas collecting pipe, and connect it to the external unit through the gas collecting pipe, so as to play a circular role. This type of product used to be directly drawn from the copper tube and then bent. Because the pipeline itself is long and the diameter of the copper tube is large, the copper tube with a large diameter is very hard and very hard when the air conditioner is assembled and the whole machine is installed later. Difficult to assemble. At the same time, copper pipes are prone to wrinkling and dead bends. At present, the existing pipeline parts have a single processing form and a variety of process combinations. Multiple solder joints and external parts are required, which not only in...
