Forming equipment for hairpin pipes and operation method thereof

Abstract

The invention discloses forming equipment for hairpin pipes. The forming equipment comprises a control cabinet, a machine table, a feeding mechanism, a cutting mechanism, a bending mechanism and a twisting mechanism, wherein the feeding mechanism, the cutting mechanism, the bending mechanism and the twisting mechanism are sequentially arranged on the machining table in the machining advancing direction of pipes. According to the technical scheme, the forming equipment for the hairpin pipes has the technical effects that the center distance between every two adjacent pipes is reduced to 15 mm from 85 mm, and the structure is more compact; the work power is lower, and the rated power is low; the number of spare and accessory parts of the equipment is reduced by about one third, the cost is lower, and maintenance is easier; the automation degree is higher, and the labor intensity is lowered; when the hairpin pipes of different lengths are produced, just the feeding stroke of the feeding mechanism needs to be changed, there is no need to replace accessories, the intelligence degree is higher, and therefore the production efficiency can be improved. The invention further discloses an operation method for the forming equipment for the hairpin pipes.

Description

technical field [0001] The invention relates to pipe fitting processing equipment, in particular to hairpin tube forming equipment and an operating method thereof. Background technique [0002] The hairpin tube is a long U-shaped tube, generally made of copper or aluminum tubes, and is the main accessory of the heat exchange tube. In actual use, it is generally connected with a short U-shaped joint to form a U-shaped tube radiator, which is widely used in the field of heat exchange. [0003] At present, hairpin tubes, especially those used in air conditioner heat exchangers, generally use figure 1 The pipe bending machine shown in the above generally adopts the method of "cutting" - "bending", which has a low degree of automation, a high rate of defective products, and there are many spare parts on the machine, which occupies a large area. A in the figure shows the length adjustment area of ​​the pipe fittings. Basically, every time a hairpin tube of a length specification...

Problems solved by technology

[0003] At present, the hairpin tube, especially the hairpin tube used in the air conditioner heat exchanger, generally adopts figure 1 The pipe bending machine shown in the above generally adopts the method of "cutting" - "bending", which has a low degree of automation, a high rate of defective products, and there are many spare parts on the machine, which occupies a large area.

A in the figure shows the length adjustment area of ​​the pipe fittings. Basically, every time a hairpin tube of a length specification is processed, it is necessary to stop the machine and manually adjust the length of the length adjustment area, which is extremely inconvenient to operate.
